Overweight Risk Essay

In the United States, increasing use of sugar in foods has led to an increase in obesity levels. Many manufactured foods have sugars that have been added. These include jams, jellies, yogurt, peanut butter, soups, candy, bars, soft drinks and many other snacks. The National Health and Nutrition examination survey indicated that the United States population has decreased its intake of fat but increased its intake of sugary and energy giving foods, while the incidence of obesity has increased (US Department of Health and Human Services, 2006). The implication here is that there is a greater likelihood of developing obesity with the consumption of sugar than with the consumption of fat. The sugar, when consumed by humans is stored as glycogen. When this glycogen becomes excessive it is converted to fats which when in excess results in the high fat deposits common in obesity. Artificial sweeteners have various advantages over sugar and these make them the preferred choice for individuals who want to avoid the health risks of natural sugar. To begin with, sugar substitutes do not have the problem of lactic acid production, consequently tooth decay is not a health hazard associated with sweeteners. The sweeteners do not undergo the fermentation process like natural sugars. The difficulty of regulating blood glucose levels is easier to manage using artificial sweeteners. Artificial sweeteners allow the individual with diabetes to enjoy a great variety of foods while maintaining close control of their sugar intake. Further, some of the artificial sweeteners even though they have a small amount of energy calories, are slowly metabolized. This means that the levels of blood sugar have some degree of stability over time and so the danger of frequent build up of glucose is overcome. Reactive hypoglycemia is common when foods with high glycemic indices are eaten. Reactive hypoglycemia is a condition where excessive insulin is produced when glucose has been rapidly absorbed into the bloodstream. This results in levels of glucose in the blood falling between the required amount for brain function (WHO Technical Report, 2006). Artificial sweeteners general have low glycemic indices making them a better alternative. Despite the advantages associated with artificial sweeteners, those are certain side effects that have led to controversy concerning their use. Some of the claimed side effects include headaches, behavior changes, seizures, cancer and respiratory difficulty as well as dermatological problems. The safety of artificial sweeteners use is a great bone of contention because many studies have findings that differ greatly, with some studies concluding that sweeteners are ‘safe at any dose’ while others conclude that sweeteners are ‘safe in all conditions’ (Pizzorno et al, 2005). Generally, most people are of the view that when sweeteners are used in moderation, the risk of adverse effects is minimal. The more important issue of risk-benefit ratio is however, still unclear. Several studies show that weight-loss is not an effect which can be directly associated with artificial sweeteners . On the contrary, people using artificial sweeteners may increase weight. This is because the knowledge that one is reducing calories intake by using artificial sweetener may cause them to ‘compensate ‘ and thus eat foods that have high energy values resulting in weight gain rather than weight loss (De Noon, 2005). Sucralose is an artificial sweeteners about 600 times sweeter than sugar. It is produced when sucrose has three of its hydroxyl groups removed and replaced with three chlorine atoms. It is commonly found in chewing gum, baked goods, frozen desserts and is usually absorbed only minimally by body and leaves the body without any changes occurring to it (Renwick et al, 2000). Sucralose has been approved by the FDA and much of the controversy associated with it has more to do with marketing than with safety. Its marketing slogan makes it appear as though it really is a sugar where in actuality it is a raffinose, a carbohydrate made up of three different sugar molecules. Saccharin was created from derivatives of toluene. Its sweetness was discovered as is the case with several other sweeteners. The substance is also made form phthalic anhydride. It is about 300 to 500 times sweeter than sucrose and is commonly used in toothpaste, dietary beverages and foods. It however has a bitter aftertaste which is minimized through blending it with sweeteners (Pizzorno et al, 2005). Reports from a study that associated saccharin with causation of cancer of the bladder led to controversy surrounding the use of saccharin. Some countries like Canada banned the product while the USA was considering an FDA ban. Further research however, revealed that it could not be dangerous to human beings, causing the threat of an FDA ban to be lifted (Pizzorno et al, 2005) Aspartame, a white, odorless, crystalline powder whose derivatives are aspartic acid and phenylanine is about 200 times sweeter than sugar. It can be utilized as a table sweetener or it can be used in frozen desserts, changing gum, gelatins and beverages. It however has the shortcoming of reacting with other flavors of food resulting in a taste that is slightly different from sugar. Aspartame undergoes metabolism to form the amino acids aspartic acid and phenylalanine. It has considerably low energy values. Safety tasting of the sweetener however resulted in findings that showed that aspartame caused brain tumors in rats. The sweetener was however, FDA approved following deliberation and results o a study done in Japan (Whitmore, 1996). There has been debate on the value of extrinsic sugar to the health of an individual. Extrinsic sugar enhances the taste of food but as it does so it also increases the amount of calories resulting in negative effects to the health of an individual. The nutritional advice by the United Nations following a report compiled by two of its agencies (Food and Agriculture organization, FAO, and World Health Organization (WHO) ) is that free sugars should account for only as much as 10% of the total intake in a diet that is considered to healthy. The free sugars in this case include simple sugars (monosaccharides and disaccharides) that manufacturers add to foods, as well as those added by consumers themselves and cooks. It also includes sugars that occur naturally like fruit juices, syrups and honey (WHO technical report, 2007). The report goes on to recommend a range of between 55% and 75% of carbohydrates for total energy intake (WHO technical report, 2007). The food industry generally favors artificial sweeteners or natural sugar sweeteners. This is because of the high profit margin realized with the use of artificial sweeteners as they are more cost effective than both corn syrup and sugar. The sweeteners however should be used by consumers with great caution to ensure that the sweeteners do not end up becoming more of a health hazard than a means of achieving good health.

Level 5 Diploma in Leadership for Health and Social Essay

   Review the range of groups and individuals whose communication needs must be addressed in own job role. In my role as Team Leader with Deputising Responsibilities, I have a wide variety of people and organizations with whom I must communicate. On a day to day basis I must meet the communication needs of the service users, with whom I would ordinarily use a relaxed and informal tone and, in some cases, short words and phrases to simplify my language. At the moment, all of our service users are fully verbal in their communications so no Makaton is required. When dealing with management, CQC, other agencies, professionals and parents or family, I would use a more sophisticated level of language but often find myself simplifying things here as well as there is a very wide range of understanding within this group. In all aspects of language (verbal, written, body, and facial) and with all interactions I need to be very conscious of matters of confidentiality and insure that I do not give out information that is not specifically sanctioned for dissemination to the particular audience in ques tion. Explain how to support effective communication within own job role. In my role it is important to develop and maintain good interpersonal relationships with everyone that I deal with; this provides a substrate for all levels of communication. One of the ways that I support others to maintain effective communication at my workplace is by providing easy access to, and easy to use, template documents for staff to use when they have information that needs to be passed on. I listen to staff needs in this area and this has helped to keep the system simple and accessible. Maintaining a feeling of unity between the shifts also helps to promote good communication from one day to the next. When dealing with staff, I try to use language  that makes them feel supported and part of a team. In some cases, it is necessary to simplify language for those staff that have English as a second language. It is also important to support these members of staff when asking them to prepare written reports or documents as extra help may be needed. In order to ensure good com munication I may ask a service user to tell me what they understood of the things that I have told them or an issue that has been discussed. For some service users I would write down the main points or answers to questions in order to provide a concrete response to an issue that has been a cause of worry, or if they are having difficulty remembering, as a visual reminder. When writing reports for management or other agencies, I try to be succinct and accurate enough to communicate the issues without going in to extraneous detail to unnecessarily lengthen documents. Analyse the barriers and challenges to communication within own job role. Within my own job role, there are many issues that prove to be obstacles to clear communication. Time pressures often mean that one issue arises before the previous one has been successfully concluded and documented. The service users often want staff support for the full number of hours that they are allocated and have no understanding that this time must include paperwork such as writing records of conversation or case file documents that are essential for other staff to be able to work effectively with them. The demands of confidentiality can also provide obstacles where some information may help one party to understand the issues being experienced by another party, but it is not appropriate or acceptable to share that information. The number of sources of information can also be a barrier to all of the information being shared between staff i.e., notice board, log book, communications book, staff folders, emails, diaries, records of conversation/observation, handover book, etc. W hen starting a shift, some staff may find it difficult to access the relevant information before their service user wants their support to commence. Evaluate the effectiveness of existing communication systems and practices. As a service that has been open just over a year, we are still refining the methods and systems of communication within the service for internal staff communications. There are several sources of information (as detailed above) where various types of information are held. The day-to-day information is passed from one team to another via the Team to Team Daily Handover book which is the first place to look when commencing a shift. This document then directs the team coming on shift to any other important documents relating to the events of the previous shift and this is working well at the moment. The information specific to each service user is kept in a Case File folder, the format of which has changed several times over the last year and this has lead to a considerable amount of work for team leaders and keyworkers, but this should lead to an effective and much more user friendly format in the future. We have also created one page summaries for each service user so that new staff o r agency workers can quickly familiarise themselves with the individual that they are about to support. The main obstacle to effective communications, both within the service and externally, is time pressure and the frequency of multiple issues arising concurrently. This makes it difficult for staff to record information fully and accurately and is an area where it is very important that the staff are supported to be able to complete this work. Lack of IT skills also impairs the effectiveness of document filing so staff need frequent reminders of how to title documents so that they are easy to trace from the digital repository. Complex computer systems also leave us with connectivity issue that mean staff and management cannot always access the required server for filing or retrieval so temporary folders are used until connectivity has been restored. This can cause problems if the issue is not resolved before the next shift arrive but can be passed on via the Team to Team book. Our IT systems are being overhauled at the moment. Compare the effectiveness of different communication systems for partnership working When working in partnership with the many external organisations that share the common goal of finding the best support and outcomes for our service users we have several ways of sharing information. Our primary method is  usually email, and this is preferred as it is a clear and traceable system that allows us to track what has been sent to whom, when it was sent, and if a response has been received. We do log phone calls and make written records of the conversation, but these are less concrete as they are only recorded by one side of the conversation and could be disputed. Minuted meetings are a very useful method as this enables professionals to come together and have input that can be acknowledged or disputed in real time and decisions can be agreed upon without the delay of waiting for written responses. This takes time and organisation to schedule at a mutually convenient time for all required parties and is not always practical for those residing at considerable distance fro m the planned meeting. Explain legal and ethical tensions between maintaining confidentiality and sharing information. The Human Rights Act, article 8 states that â€Å"Everyone has the right to respect for his private and family life, his home and his correspondence†. The Data Protection Act 1998 governs how we collect, store, share and dispose of information. The sharing of information is an essential part of providing high quality, person centred care and for running an effective service. As a service that holds a considerable amount of data on our residents it is important that we have procedures in place to protect the confidentiality of that information. It is a legal requirement and our moral duty to not share any of this data with individuals, companies or funding authorities that are not directly concerned with the individual in question. Even within our own organisation, we will remove identifiers (names, initials, dates of birth etc) from some documents before we share them with other dep artments and codes are often used to identify service users within documents in order to protect their privacy. There are times, however, when we also have a duty to disclose information about an individual if we know or suspect that a situation could arise where harm is caused to another person or group. In any such case we must decide â€Å"†¦whether the release of information to protect the interests of a third party exceptionally prevails both over the duty of confidence owed to the service user and the public interest in a confidential health and social care service† ( http://www.dhsspsni.gov.uk/confidentiality-code-of-practice0109.pdf ) This  could include, but is not limited to, the reporting of abuse to protect others from the abuser, or informing the DVLA that a service user is now taking medication that renders them unfit to drive if the service user is refusing to do so themselves. In all cases, an attempt should first be made to gain consent from the indivi dual concerned using communication appropriate to their needs. Analyse the essential features of information sharing agreements within and between organisations An information sharing agreement (ISA) is a set of rules for all involved parties to adhere to when sending, receiving, processing, storing and disposing of data. It should be structured to benefit the service users and they should be confident that their information is being handled in a secure and responsible way. It should be a clear document written in plain language that is easy to understand. The ISA should state why the information is to be shared, the organisations that are involved, the types of information to be shared and how this complies with the Data Protection Act (1998) and the Freedom of Information Act (2000). There should be clear guidance on the amount of information to be shared to guard against irrelevant or excessive information being included. Template documents for requesting and sharing information should be included as this will support the standardisation of data set to ensure information is being recorded consistently across the organisations involved.

Strategic management is the process meant to draft, implement and evaluate functional decisions that enables an organisation to achieve its long term goals. Ackermann & Eden (1998) states that strategic management involves the mission, vision, objectives as well as policies designed to achieve these set objectives. This model has got various theories and model. These include; Porters five forces. These forces determine the competitive intensity and attractiveness of the market. To begin with we look at the threat of new competitors. In a market situation especially a profitable one, may result to high output that attracts investors and therefore decrease the market share. To deal with this problem, a manager needs to set up objectives and strategies that will maintain their customers. These strategies may include customer loyalty. Another force is the rivalry between existing firms. This is where firms operating on the same level compete for market share and profitability (Ackermann & Eden 1998). Managers set up strategies based on price, quality and innovation of brand names. Competition can mostly be avoided through technological progress. Bargaining power of buyers is also categorised in the porter’s five forces of strategic management. It can be defined as the ability of the buyers to make the firm run under pressure. It also involves the bargaining power of suppliers and the threats of substitutes that affect a market situation. In reference to the above models, I think the perceived strengths would be insisting on customers’ royalty. This is because the customer will always be right. If this objective is enhanced then there will be increase in market share as well as firm’s output. The weakness of practicing this model is that most firms would not afford raw materials such as capital to influence

After she had run away from her second foster home at thirteen years of age, she had ensured that till sixteen years she would remain at the orphanage and study. Thereafter, she would move to a new place and pursue higher study while working. She had left Dakota when she was sixteen. She is a very determined young lady who is not only smart but also very intelligent and focused. She does part time cleaning job at the IT firm and works late night shift at the local bar as waitress. As jobs are scarce, she believes that any work would do so far as it is able to pay her college fee. Her black belt in Judo has helped her to ward off the attention of street Romeos and drunkards while working later night shifts or attending night classes of management. She shares her accommodation with two other girls who have now become her best friends and family. While this may not give her the requisite privacy, it nevertheless has helped her to survive in new place Her short term goal is to get management degree and later do apprenticeship in some established company. She has already talked to her supervisor at the IT firm who has assured her that once she gets the management degree, she would be considered. The firm employs young talents and gives them huge opportunities for growth. She had also made friends with many people at the firm who also help her in gaining computer skills.

Will hourly hourly rounds decrease patient falls Research Paper

Will hourly hourly rounds decrease patient falls - Research Paper Example The sample size, instruments and the data collection methods used in all the researches is different and variable. Conceptual framework: first the patient falls in a hospital is tested then the hourly rounds system is incorporated and then again the patients falls after implementing the system is checked and its effect on the patient as well as the nurses is concluded. Research Reports: A study conducted at Crestwood Medical Centre in Huntsville in Alabama reports a high decrease in patient falls after the hourly round system was adopted by the nurses. Hourly rounds instituted in October 2007 were designed to reduce the number of patient falls. â€Å"The initiative, which was designed to reduce common problems associated with hospital stays, has resulted in a 58 percent decline in accidental patient falls and a 39 percent decline in bedsores† (Krischke, 2011, para. 2). When a nurse makes a round, then she makes it a point to check with the patients whether they need help for going to the washroom, or whether they need to change position etc. Nurses also enquire about the patients’ pain and to put in place their possessions like emergency bells or calling bells, water etc which have to be kept near the bed. This will help in avoiding unassisted moves, which may entail falls and obviate the necessity for unnecessary moves. A study conducted in the surgery and the oncology departments of San Francisco General Hospital between the months of June to August 2009 reveals that there were 50% decrease in patient falls in the hospital after implementing hourly rounds system by nurses. Hourly rounds are also necessary in intensive care units (ICU) and these will provide the patients and their relatives immense satisfaction about the patient care being provided by a hospital. Besides, there is ample evidence to suggest that the practice of hourly rounds by nurses is an effective â€Å"intervention that can be implemented to reduce the number of patient falls† (RN &

Innovation. Innovative techniques of a manufacturing company Assignment

Innovation. Innovative techniques of a manufacturing company - Assignment Example It is not possible to apply the innovative techniques of a manufacturing company, in a service sector. This is because the two business models operate in different spheres, and the main different is depicted in the nature of the products they produce. The service sector deals with intangible goods, while the manufacturing sector deals with tangible goods. An example of a service is the delivery of mails, by Fed Ex Company (Chang, 2011). It is important for the service industry to create a culture of innovation while conducting their activities. This is because the service sector is a major employer, and greatly contributes to the development of an economy. However there are challenges that can prevent entrepreneurs in a service sector from innovating. This is because there aren’t any clear guidelines on how to innovate for a service sector (Chang, 2011). However, an entrepreneur can overcome this challenge by appreciating the service in which an entrepreneur provides to the co mmunity. This will create a proper mindset that will advocate for the improvement of the service to carter for the various needs of its customers. It is essential to separate the physiology, structure and the context within which the business operation focuses on. By doing this, the organization will broaden its scope of innovating, and therefore overcome the challenges that the service sector faces in developing an innovation (Omachonu et al, 2010). An example depicting an organization that appreciates its scope of operation and created ideas for its relevance in the market is easy jet. The main objective of the company is to make it easier for customers to access services. As a result of this objective, the company developed various products such as, Easy Cruise, Easy Pizza, and EasyCinema. This was possible because of the right mindset emanating from the management because of appreciating the context of their business operations. Another method of overcoming the challenges is to create a research and development department within the organization. The department should be responsible for carrying out a market research on the requirements of a customer, and on how to satisfy their needs (Dodgson et al, 2010) . The department should be responsible for analyzing the feedbacks of the sales representatives of the company, and the various customers that the organization serves. The department should also look at the strategies of the organizations competitors, and analyze their innovative tendencies. Basing on the results of their analysis, the department should advice the management of an organization on whether to copy the style of their competitors’ mode of operation, or to develop their own strategies. On this note, the R and D department is an important element of overcoming challenges that emanate from innovating in a service industry. Another method of overcoming the challenges that emanate for innovating in a service sector is to focus on the core elements of the company (Chang, 2011), this is as opposed on innovating in the supplemental elements of the company, such as friendly customer care services, effective problem solving mechanisms, after sales services, such as an extra service to the customer without any charge. These supplementary services can be copied by their rival companies. On this note, to maintain an edge over their rivals, the organization should focus on improving its core business objective. An example is the innovative ideas of CNN in making its services accessible on a 24hr basis. Google initiated measures of improving the speed of its search engine network, and Fed Ex initiated measures of speedily delivering packages to their clients by working for 24hrs a day. However, it is not only important to focus on the core element or objective of the business, it is important to focus on other supplemental elements of the business organization while creating a product that will be attractive in the market. In as much as supplementary ser

References EXECUTIVE SUMMARY Toyota has experienced brand reputation problems in the European market, making it critical to enter new markets to offset revenue losses in this part of the world. Recurring recalls have damaged the brand and a new market opportunity, Brazil, could produce revenue growth until the brand is able to re-establish its quality reputation in Europe. Brazil has a strong GDP and consumerist culture with ample incomes due to improvements in the economy and job infrastructure in the country. Furthermore, the collectivist characteristics of consumers will make it easier for Toyota to build lifestyle marketing strategies to gain the loyalty and interest of diverse, niche consumers. Competitive threats are only moderate if Toyota invests in direct investment of new and modern production facilities in the country which would outperform major competitors who are forced to work with outdated equipment and limited t echnology availability (i.e. automation). Through brand management and heavy emphasis on promotion, Toyota can successfully compete and sustain advantages in a dynamic and saturated Brazilian market. Through a joint venture with a domestic automaker, shared resources and knowledge will assist in building brand preference with a new set of niche market consumers sharing unique and disparate lifestyle characteristics. Toyota: Becoming a truly global player in the automotive industry 1.0 Introduction Toyota Motor Corporation, a Japanese multi-national, is currently the largest automotive company in the world by ratio of production output, comparative revenues and market capitalisation (OICA 2013). In 2013, Toyota sustained revenues of 22.06 trillion yen (Toyota 2013). The company produced,

Health poster - Essay Example As a result, more and more children find themselves confined to indoor play which does not give them the ability to exercise as much as they should. Even when playing outdoors is an option, many children choose to remain indoors, lured by the greater technology of video games which strongly encourage sedentary behaviour while engaging the mind (Graves et al, 2007). These problems are increased as fast food restaurants tempt children to poor food choices by adding toys and games into meals targeted for children. Recognising that childhood obesity has trebled over the last decade (Centre for Disease Control and Prevention, 2010), some cities such as San Francisco have made it illegal for fast food restaurants to add toys to unhealthy food options. The aim of the present research is to help reduce the rate of childhood obesity in the primary schools. This will be accomplished by directly addressing the changing interests of children today as well as by changing children’s self-efficacy by introducing them to the tools they need to change their lives. Targeted to overweight children in the final two years of primary school, the objective of this six-month intervention program is to reduce the overall weight of the children involved by increasing their physical activity and giving them better information about diet and nutrition. There is clear evidence that there is a growing problem of obesity among children in the developed world (Centres for Disease Control and Prevention, 2008). National Health Services (2010) has tracked growing trends of obesity in both boys and girls and a tendency for children to become more engaged with sedentary activities to the degree to which they are obese – i.e., more obesity equates with greater time spent engaged in sedentary activity. Epstein et al (2008) points out that one of the

PC Case Essay Example for Free

PC Case Essay According to Carter, â€Å"a Pc case is the basis of the computer system within which all the other parts reside. The choice of a case size determines what other components of a machine may fit inside of it. It is the visible portion of a machine system†. Some modern computer cases come with a power supply pre-installed inside them, but most of them do not. It is therefore necessary for one to get a power supply which will work with the rest of the components and which has sufficient power. There are different types of cases which include small towers, tall towers, horizontal desktops, slim desktops, and also the lunch box size and shape made popular by the Shuttle and Mini-ITX case builders. (Carter, 2002:14) Computers Pc cases are available in many form factors or rather different magnitudes. The size and form of a case in a computer is generally dogged by the motherboard’s form factor that is intended to accommodate, since this is the most central and largest component of many computers. As a result, form factors in individual’s computer typically spell out only the inner proportions and case layout. Form factors for blade servers and rack-mounted incorporate defined peripheral dimensions as well bearing in mind that these computer Pc cases must themselves fit in particular inclusions. The conservative viewpoint says that a case carries out several functions. First, it holds on to a range of form factors so as to house the different components that make up a PC. (Ashton B, 2002:33) These factors are PSU, the motherboard, PCI cards, drives and fans. It also provides noise shielding. It allows air to flow through the case in order to cool the components within it. It gives a Pc its attractive appearance. The silent viewpoint is mostly in emphasis. Form factor adherence is implicit for all cases. However, EMI looks and shielding are derivative to the main properties of airflow vents that are exceedingly unobstructed, tortuous paths which facilitate noise escape to the case, airflow paths that are well-directed within the case and low sound transmission, sturdy construction and low resonance. To help personalize Pc cases on the computer market today, majority of the computer Pc case manufacturers present with various accessories. These accessories take account of items which include a case cover that has a window that has been built-in to specialized fans and lights. Bearing in mind that the time for the standard beige box are no longer in use, users now have several factors to consider when picking out their case which include color, design and lights and windows as well. (Cheek, J, 1995:19) Design The material of the Pc and the eminence of the workmanship normally make a big difference in a Pc case. At their base most cases are made with aluminum while others are made with steel. Other materials which incorporate plastics and acrylics as well are also used to complement the design and appearance of the Pc case. These materials not only impact on the ways that heat is held in or circulated out of the system but also impact on heaviness or portability of the Pc case. It is however of great significance that individual checks how the Pc case is put together. Finished edges or rather beveled normally minimize the possibilities of cuts while working inside the Pc case. To prevent doors breakage, hinges should be sturdy enough. Power Supplies In modern days, majority of the computer cases are put on the market independently from the power supply. Nevertheless, a number of these computer cases do come with a power supply already included. In cases where computers comes with power supply already inaugurated in the case, it is importance that users authenticate that the power supply wattage meets the requirements of the mechanism that will be fixed inside. In addition, it is importance for users of the computer to check and ensure that it has the correct connectors and enough cables essential for all of the inner components. Layout The adornment of the computer Pc case and its design can unswervingly impact on its usage. The position of the fans and ports on the computer normally improves access or rather increases the style of the Pc case. For instance, when a case has been placed on the floor, it would be considered better for the extra USB, audio and Fire Wire ports to be positioned on the top of the case than when positioned on the front. On the other hand, it would be better for the ports to be on the front should the case be on the top of a desk or inside a cabinet. Drives in the rear a door panel can lessen noise and this gives the Pc case a look that is more uniform. However, although the drive behind the door panel reduces the noise and gives the computer Pc case a more uniform look, it makes it impossible to access the drives behind the door panel. Conclusion Excess heat has a negative impact on the performance of the internal components in the desktop. Due to this heat effect, cooling is considered a very important factor to bring into attention. An assortment of vents ducts and fans that are built into a Pc case either aids or deters the flow of the heat from the internal to the peripheral parts of the case. A computer Pc case with a large quantity of the flow of air can also lead to a large amount of dust buildup inside of the case. However, the amount of dust in the computer Pc case can be reduced by acquisition of Filters and screens that are designed to help minimize dust in the Pc case. (Hill, P. , 1995:29) In order for one to have silent computing, unrestricted airflow vents should be used. A major approach is the use of quiet fans which work at reduced speed to eliminate the noise produced by fans. Since the volume and the pressure of airflow is significantly lower than that of a standard PC, any hitch at the vents creates a quite a large negative effect in temperatures. Well-directed Airflow Path in the Case is best accomplished by reducing the number of superfluous holes in the Pc case. Randomly placed holes on the sides of cheap cases, for example, tend to disrupt the ideal flow of air, which is generally seen as from front bottom to the back top. (Moir A,1991: 23)

The Story of an Hour Essay Example for Free

The Story of an Hour Essay The Story of an Hour† by Kate Chopin, interprets the liberation of subjugation and a despondent marriage. The nineteenth century setting is that of a man’s world.   The general plot of â€Å"Story of an Hour† symbolic of anticipation of possibilities for women abiding the tyrannical impact of a male- controlled society. For Louise Mallard she had a fitful response when she learned that her husband has been supposedly killed in a train mishap. She confines herself in her room and sits in front of the window in isolation. She begins to muse about life without her husband. Commencing with distress, Louise slowly converts to joy. â€Å"Free! Body and soul free!† (Chopin, n.d.). Louise knew that the normal response was to grieve the death of her husband, but deep within her new found liberation procures. Decisively she imagines living for herself and achieving things she had yearned to accomplish. Louise does not see this as adversity but as an opportunity, another endeavor at life. Compelling belief of freedom ends in dismay when Brently Mallard arrives at the door, alive and well. â€Å"Someone was opening the front door with a latchkey.† (Chopin, n.d.) Profound freedom was merely reverie. Ironically her disarray of emotions ultimately led to her death. Louise dying of simple â€Å"heart disease† reveals that her emotional agony was internal. The theme in â€Å"The Story of an Hour† is the role of men and women in the 19th century. Life was male dominated, with women being prisoners of their husbands. In the story Louise Mallard is jubilant that she would no longer  have to stoop to the desires of her husband. There is one primary conflict in â€Å"The Story of an Hour†. The conflict is internal and one of freedom versus the imprisonment of the marriage. Mrs. Mallard, hears of the believed death of her husband, she is impaired with a heart condition, and the news could possibly kill her. Further reading explains, she is merely an animal in a glorified pen. The death of her husband would offer freedom and understanding that she has been trapped in a marriage in which her husband dominated her, which has created a conflict within her. Therefore, the desired freedom being an internal conflict. In conclusion, â€Å"The Story of an Hour† is of the nineteenth century formation of male oppression and the thoughts of freedom resulting in death.

Communication Skills in Health Assessment

Communication Skills in Health Assessment An Evaluation of the communication skills demonstrated in the assessment of a service user This essay will evaluate an admission assessment observed a specific assessment observed which was done by mentor. Communication skills that she used will be analysed. Furthermore appropriate literature will be used to understand if the communication skills that were used were the most effective as well as that of both verbal and non-verbal communication skills. All names have been changed for patient confidentiality in accordance with the NMC guidelines (NMC, 2008).The patient will be referred to as Mrs. Smith. Mrs. Smith is an 80yrs old lady widower living alone in a bungalow. She was admitted to the ward from AE. She depends on his son who lives a few miles away and visits him twice weekly. Mrs. Smith was diagnosed of COPD 10 years ago and Ischaemic heart disease 4 years ago. He smokes 40 cigarettes a day. Currently, he is on Salbutamol 200mcg/dose dry powder inhaler 1 puff as required, Spiriva 18mcg inhalation powder capsules once a day, Nicorandil 20mg tablets one twice a day, Simvastatin 40mg tablets once daily and Glyceryl Trinitrate 400mcg/dose pump sublingual spray as required. Over the past few years, he has been admitted to hospital three times owing to exacerbation of COPD and has had a bad chest infection yearly for the past few years. Mrs. Smith has not been well for two days and has been coughing and wheezing with increased Phlegm and a temperature. She lost quite remarkable weight in the past few months because she has not been eating and drinking well. Mrs. Smith could hardly finish a sentence without gasping for breath and appeared anxious when the General Practitioner referred him to hospital. The assessment was done by mentor included the EWS’s. Assessment is the first stage in the nursing process. Kozier, et al (2012) stated that assessment is a systematic collection of data with a view to identifying the patient’s actual and potential health problems. A complete and holistic assessment should take into consideration the individual’s psychological, social, spiritual and cultural needs (Matthews, 2010). Collected data can be subjective or objective (Hoffman, Aitken and Duffield, 2009). Full assessment should be systematic, patient oriented, evidence based and holistic; and nurses should seek informed consent from a patient before initiating assessment, any treatment or care (NMC, 2008). Consent was sought from Mrs. Smith to conduct an assessment on her. There are three types of assessments namely; mini, comprehensive and targeted. Targeted assessment was used in assessing Mrs. Smith. Vital signs were recorded to establish the baseline observations which help in early recognition of patient deterioration allowing early intervention before the patient’s condition worsens (Adam, Odell and Welch, 2010). Mrs. Smith’s respiratory rate was recorded as 21 breaths/minute, implying dysponea whereas normal respiratory rate ranges between 12 and 18 bpm (Dougherty and Lister, 2011). His pulse was 102 beats/minute confirming tachycardia against a normal pulse range of 60 to 100 beats/minute (Hastings, 2009). Nurses should count the pulse and respiratory rates for a full minute each, giving ample time to observe any abnormalities in pulse rate, rhythm and volume (Smith, et al, 2008). With normal blood pressure ranging from 110/60 and 140/90mmHg (Bishop, 2009), Mr Smith’s blood pressure, measured using both an electronic device and a manual cuff was recorded as mild hypertension at 160/90mmHg. Temperature was checked using an electric tympanic thermometer and Mrs. Smith had moderate pyrexia with a core temperature of 38.9 degrees Celsius indicating possible pathogen invasion (Smith and Field, 2011). A normal core body temperature ranges between 36 to 37.5 degrees Celsius (Smith and Robert, 2011). Arterial blood gases (ABG) test analysis was conducted and pulse oximetry was used to record oxygen saturation which read 87% suggesting hypoxemia. Both Felton (2012) indicated that ABGs analysis produces more accurate oxygen saturation than pulse oximetry. My mentor failed to introduce herself first before she touched the patient, which is important when conducting with patients during the time she did the observations. (Henderson ,2004) stated that nurses have to show impression by recognizing yourself as well as your role delivers patients with the sensitivity that you are honest and that they are being appreciated. Mrs. Smith was given a verbal informative account of giving him oxygen therapy and the reason for doing this by my mentor. Verbal language is one of the vital ways in which we communicate and is more helpful way in both gathering and updating patients of their disorder (Berry, 2007). Communication can be verbal and non- verbal.Peate (2005) states that non- verbal communication reinforces a verbally communicated message. Non-judgemental interactions are focused on therapeutic communication, helps settle emotional conflicts and supports heart to heart talks allowing a patient to feel safe and free to share their true feelings, fears, values, hopes and ideas. There are two ways to send a message and it has to be understood and the feedback to be given (Apker, 2001).A patients has to describe the level of his pain (Steveson, 2004). Nurse must make sure that the patients understands what has been said to them and that it is important (Grover, 2005).Close and open questions normally have the ability to determine a huge amount of accurate information. Mentor who administered oxygen therapy to Mrs. Smith did verbally tell Mrs. Smith what she was going to do since this process has not been done earlier to ensure that Mrs. Smith had understood the process which was going to be done. My mentor was aware of Mrs. Smith’s disorder but she failed to make sure that she agreed the procedure. Unfortunately if one does not practice listening skills correctly and related skills without the patient fully considerate can disturb the beneficial connection and often form an obstacle to message (Andrews Smith, 2001). Environmental obstructions such as a busy ward or a strained nurse can every so often decrease the level of kindness and impact real message (Endacott Cooper, 2009). On the other hand nurses must remain sympathetic all the times towards service user’s regardless of pressure altitudes and amount of work (Von Dietze Orb, 2000).My mentor’s procedure did not act in accordance with the NMC guidelines in respects to gaining consent as she failed to notify the patient of the procedure then Mrs. Smith would not recognised what she was agreeing too. Agreement is complex and it can carries a grade of risk for both service user and healthcare staff. In this state Mrs. Smith was incapable to give consent and the oxygen that acquired was in his best interest. Though, regardless of the service user’s understanding the agreement of consent must still be tried (Green, 1999). Timby, (2005) recommends that a service user’s right to self-government must be supported and ap preciated regardless of gender, race, religion, culture and disability. On the other hand well experienced communication procedures are incompetent if the significant idea of the interactive links goes misunderstood (Arnold Boggs, 2007). Charlton etal (2008) debate that there are two unlike statement styles, biomedical and biopsychosocial. The biomedical style focusses on specific evidence relating to the service user’s disorders that is evidence focused. The biopsychosocial style is a patient centred approach which is directed by determining patients’ requires to offer the most existing message method. My mentor if possible should have designed an action plan to regulate the lively method of collaborating with Mrs. Smith in order to carry out the oxygen procedure. For example every patient is not the same their requirements must be measured prior to carrying out any invasive methods. A patient centred method is said to have a more confident impression on patient results. On the other hand there is slightly study that debates personal skills in compared to a massive amount of rich study that argues simple communication skills regardless of proof suggesting that patient focused on care is the most actual manner (Jones, 2007) Patients with breathing problems have difficulties in speaking especially when they are out of breath. The will have problems in communicating sometimes have barriers when trying to speak or trying to explain themselves. This indicate to a failure in communication and sometimes it can cause their health requirements not be met (Turnbull Chapman, 2010). Kacperek, (1997) describes non-verbal communication as the word used to use to describe all methods of communication not organised by language. Argyle, (1988) advocates that the non-verbal element of communication is five times more prominent than the spoken aspect. When Mrs. Smith was given oxygen, my mentor did not the use of non-verbal communication. Research have time and again revealed that language has no real incidence when interactive with patients (Foley, 2010). Non-verbal achievement such facial expressions,posture,touch eye contact and body language, display many feelings need to have verbalise (Foley, 2010). The Solar acronym is also an aid to recognise and think of the performances that should be applied in order to accomplish real communication (Burnard, 1992). This tool includes of position of seat, leaning near the patient, eye contact and relaxation. If the method of non-verbal communication been there Mrs. Smith might have not been nervous and she should had felt more comfortable (Mason, 2010). Dougherty Lister, (2008) is in contract with this model as he argued that remaining eye contact, take down position to the patient’s level and gently touching the service user hand whilst talking to them it helps them not to be scared. However touch is seen to be a real system of nonverbal communication which be able to put a service user at relax if they are worried or frustrated. It is insignificant to note that this method is not suitable for all patients as not all patients will feel relaxed with understanding can give this as attacking of individual’s space (Heidt, 1981). Communicating with people with COPD appears to problems for health care givers (Thornton, 1999). However, the NMC, (2015) competency standard in still that all nurses are to provide best excellence sympathetic care near moral and cultural issues as well as ill health. Jormfeldt, (2010) has presented that a great level of nursing teachings in both academically and practical settings can definitely impact attitudes of nurse’s views near patients. On the other hand, reflection is appreciated as an important factor of managing in these situations as it gives a method where undergraduate nurses can challenge, relate and analysis their assessment systems and hold the method of alteration to a helpful approach concerning patients with illnesses. Dodd Brunker, (1999) debate that by creating combined partnerships with both carers and authorities who are involved in the patients care can support you to evaluate the patient’s communication skills and their chosen ways of communication. Additionally, in agreement with the NMC (2015) rules it is important that all nurses must treat all patients with respect and self-esteem and not differentiate in any way regardless of their age, gender, race and or disability. To develop the circumstances the nurse who administered the oxygen to Mrs. Smith might have communicated with the patient’s family. Since she came to hospital accompanied by her son, this might have given my mentor a good image concerning Mrs. Smith’s about what she enjoys mostly and what she does not like. This might have given her with the greatest means of method of how to carry out all the process. Family members could have been asked to be there with my mentor which might have allow Mrs. Smith to relax. Nurses should every time put patient’s individual requirements first and recognise what is good for the patient morally rather than that of a qualified staff views only (Mencap, 2007). In conclusion, this essay has revealed the communication skills that were observed throughout the oxygen therapies procedure. It is clear that communication is important in nursing care and that assessments of patients are vital in providing the patient centred care. Though, communication is certainly a value powerful for the real caring. Performance and communication of caring and capability at this time have a main effect on the ability of patients and relations to adjust the update, reflect choices, and adjust to anything deceptions forward. Absence of responsiveness in regards to the best method of communicating with patients can position a great risk to patients as several individuals employed within the healthcare area may not have a perfect understanding of ill patients except they are specialised. Extra preparation may be required to make sure that all wellbeing care workers are capable to offer kindly care to patients with disorders. Patients with illnesses have the right to be cured the similar methods as others, regardless of the severity of their illness as all service user would be allowed to a trained staff and genuine service throughout their understanding surrounded by the healthcare atmosphere.

The Author To Her Book :: essays research papers

Writing poetry can be a deeply personal (and sometimes painful) process. If talent and luck prevails, the poet will actually produce a something that reflects the inner workings that first motivated their pen to meet paper. Through struggle and sweat a poem is born, and for better or for worse the creator is responsible for the subsequent journey that it will take throughout it’s poetic life. In it’s infancy, it might seem a miracle of creation, but like most parents the writer will work at maturing the verse and rhyme so that it can defend itself when it eventually leaves home. The world that it will one day enter is a cold and critical one, and few will understand the true meaning and depth of the poem’s soul like it’s parent does. Anne Bradstreet beautifully demonstrates the intimate relationship that exists between an artist and her work in the poem The Author to Her Book. In the poem she directly addresses the book that was published without her consent, referring to it as her child, kidnapped and exploited in a world of criticism. By exposing the her work to the world, she feels that her own inadequacies are revealed as well, thus creating an internal struggle between pride and shame. This paper will take a detailed look at the poem line by line, and draw out the deeper meanings that Bradstreet injected in regard to the book The Tenth Muse Lately Sprung Up in America, her illegitimate brainchild. In the first line Bradstreet refers to the book as an â€Å"ill formed offspring of [her] feeble brain.† This not only expresses her opinion of the work, but also that of her own abilities as a poet. She seems to feel no confidence, and says so upfront, as if to apologize to anyone who might have encountered her work. Although its flaws embarrass and shame her, she understands that her book is the offspring of her own "feeble brain", and the lamentable errors it displays are therefore her own. In lines two through four she shows that her ‘child’, once safely kept close to her side, suddenly â€Å"snatched† away by friends â€Å"less wise than true,† and then â€Å"exposed to public view† before it had a chance to mature in her care. It’s in Bradstreet’s strong descriptive language that she is able to express her feelings of betrayal. Though she doesn’t outright say it, she obviously felt deceived, and suffered the same exposure that the book had.

Hedge Fund Policy Essay -- Economics Wealth Papers

Hedge Fund Policy What makes a hedge fund such a unique investment? And why is it so controversial? Many feel the risks of a hedge fund strongly outweigh its benefits. And with some funds, it does. But when a hedge fund strives, it has impeccable potential. It is arguable that the regulation on hedge funds, or lack there of, is what allows for so many to falter. However, despite various suggestions for policy changes, a few lemons still remain. Would changes in policy and regulation of a Hedge Fund allow it to be a more attractive investment opportunity? Although some alterations could make the hedge fund a safer investment, some risks are completely unavoidable. Ultimately, these changes may not only create more problems, but also take away from the uniqueness of this remarkable form of investment. A hedge fund is typically a private partnership invested primarily in publicly traded securities or futures. They are limited to 99 investors and require large minimum investments, which can range from $25,000 to several million dollars. Sixty five percent of the investors must have a net worth of at least $1 million. A general partner, who uses sophisticated strategies to make bets on the fund?s direction, and generally receives 20% of the profits, leads the fund. Hedge fund strategies fall into four open categories: absolute return, long/short equity, event driven, and global asset allocation. Absolute driven strategies are known as "market-neutral" funds, which seek to moderate the effects of overall market forces. Long/Short hedge funds, which represent about half of the assets in the hedge fund industry, seek to profit from underpricings by buying long, and overpricing through short selling. Event driven hedge funds ... ... able to grow and have the leverage it had, if it had not been lent the money," said Bert Ely. Though many may argue that hedge funds do more harm than good, they are still extremely popular investments and have proven to be very successful. Many have benefited with the current hedge fund policy and see no need for regulatory changes. Various proposed changes may not, in fact, be entirely beneficial. Once implemented, the suggested solutions could create more problems for the hedge fund world. And such changes would alter the characteristics that attract so many to such incredible investment opportunities. In the end, a better hedge fund policy is neither plausible nor desirable.

The Plight of our Planet Essay -- Energy Sustainability

The young boy looks back from the loading ramp of the giant metal alloy ship, his breath billowing clouds of steam in the bitter air made cold by the now almost completely diminished ozone. He stares in disbelief at the endless pile of automobiles parked haphazardly to and fro like a child’s worn jenga blocks fallen from a poorly made tower in the vehicles owner’s frantic rush to get their families to the evacuation ships in time. How did it come to this ¬Ã‚ ¬? The forlorn boy wonders. When did it all go wrong in mankind’s endless quest to be bigger, faster, and more powerful than all the rest? As the nearly city-sized ship reaches the smoky horizon bound for humanity’s new home named Kepler-22b, he gazes one last time at the vast oceans, blazing a filthy orange fire as far as the eye could see from the final disaster that had sealed humanity’s fate on earth. If only they had stopped drilling in the oceans—the boy thinks. And as the distanc e grows and the bright fires fade, he tearfully waves goodbye to the now dying planet his race had called home for a millennia and slowly turns to go find his parents. Who is this distraught boy’s parents? Is it you? Or perhaps it is your children’s children that are living through this arguably inevitable reality. While the scenario presented is sensationally far-fetched, it is entirely possible. Perhaps not a mass exodus to a new found planet capable of sustaining life, and even if we were lucky enough to find such a planet it would likely not be accessible, nor needed in this generation’s lifetime. But the simple truth remains that earths sustainability is quickly diminishing due to a plethora of causes. Some of which are our societies numerous recent technological advances in the last century,... ... leaders of tomorrow. References Carbone, N. (2011, December 5).

Curriculum For Excellence Impact On Teacher Professionalism Education Essay

The being of a relationship between course of study policy and instructor professionalism would look to be an established premise. This is apparent in claims that course of study reform is frequently regarded as a menace to teacher professionalism ( Al-Hinei 2003 ; Apple 2009 ; Locke et Al. 2005 ) . Most notably, it is frequently claimed that the degree of prescription in the English National Curriculum, with the associated demand to run into the prescribed results, reflects a decrease of instructor liberty in favor of answerability ( Walsh 2006 ) . It would look, at this degree so, possible to reason that a decrease in cardinal prescription equates to an addition in teacher liberty which in bend equates to an sweetening of instructor professionalism. To an extent this would look to be an purpose of recent course of study reform in Scotland in the signifier of the Curriculum for Excellence ( CfE ) . The first page of the first ‘Building the Curriculum ‘ papers that claims that ‘teachers will hold greater range and infinite for professional determinations about what and how they should learn ‘ ( Scots Executive 2006:1 ) . However, such a straightforward relationship between course of study policy and instructor professionalism would, pulling on Evans ( 2008 ) , be an over-simplification. Evans suggests that professionalism can non be understood entirely, through analyzing instructors ‘ ‘remit and duties ‘ ( p.23 ) , and instead we must see instructors themselves understand their professional duties. To an extent this would look to be recognised in Scotland ‘s course of study reform, in for illustration claims that the reform requires a ‘culture alteration ‘ ( Scots Government 2009a:5 ) and the accent on the demand for professional development ( Scots Executive 2006:2 ) . This suggests acknowledgment that a alteration of instructors ‘ remit and duties entirely will non impact upon professionalism. In visible radiation of the perceived association between CfE and teacher professionalism – both as stand foring being and necessitating a alteration – it becomes pertinent to see the nature of the professional opinions that greater teacher liberty over the content of the course of study entails, and hence the construct of professionalism it would look to connote. This requires a consideration of the peculiar issues that are associated with the choice of course of study content, and an scrutiny of different constructs of instructor professionalism. Course of study First hence, we must see what is meant by â€Å" course of study † . As a term it would look to be notoriously difficult to specify, with a battalion of potentially conflicting definitions ( Dillon 2009 ) . By and large it can be suggested that ‘curriculum ‘ does non mention to a list, or patterned advance, of points to be taught. The course of study addresses non merely what is taught, but why and how instruction and larning takes topographic point. As such, curricula reflect and advance beliefs about the purposes and nature of instruction ( Flinders & A ; Thornton 2009:8 ) . They reflect different epistemic and pedagogical beliefs – beliefs about the nature of cognition and acquisition and learning – in, for illustration, their administration of ‘knowledge ‘ ( Carr 1988 ) , for illustration those that emphasise the separation of cognition into topics and those that favour integrating of capable countries. However it should possibly be no ted that Carr ( 1988 ) argues that the epistemic and pedagogical bases of much course of study policy is non wholly coherent. It should besides be noted that the current treatment is centred around the construct of ‘explicit ‘ course of study ( REF-moore? ) , – course of study as a statement of the planned or expected acquisition within a school context. Other constructs regard course of study to embrace all the experiences which impact upon a scholar ‘s development ( REF-Dillon? ) . However, notwithstanding the scope of attacks to understanding and making course of study, course of study design needfully entails a choice of what is to be taught. Different course of study theoretical accounts may differ in both when and by whom this procedure of choice takes topographic point. In a to a great extent normative, centralised, curriculum much of the choice is being made by policy shapers. At the other extreme, in a strongly child-centred course of study, choice is mostly made by the kid based upon their involvements. ( BACK THIS UP ) . If we consider the CfE itself, it is apparent that it can non be considered to be puting the determination of what to learn entirely in the custodies of instructors. Priestley ( 2010:23 ) suggests that it reflects a tendency in course of study development in general, in which there is an effort to pull on both ‘top-down and bottom-up attacks to curriculum be aftering ‘ . A procedure of choice has already occurred at the nat ional degree in footings of the signifiers of cognition and accomplishments that are to be developed. Even within this ‘clear model of national outlooks ‘ ( Scots Executive 2006:1 ) , instructors do non hold exclusive duty for course of study content choice. In the pledge, ‘all kids and immature people should see personalisation and pick†¦ ‘ ( Scots Government 2008:17 ) , there is an outlook that students will, to a certain extent, besides be doing determinations about course of study content. Further, there is a strong accent upon collegiality, with instructors working together on course of study development ( Scots Government 2009 ) . However it clearly does take to put more duty for pick in the custodies of the instructor, and in making so is potentially impacting the nature of instructor professionalism. Professionalism In order to analyze this claim more closely it is necessary to see the significance of ‘professionalism ‘ itself. As with ‘curriculum ‘ , it would look that ‘professionalism ‘ is a hard term to specify with many different positions as to what it truly means ( Al-Hinei 2003:41 ; Evans 2008 ) . By and large nevertheless, the term ‘profession ‘ may be regarded as bespeaking a distinguishable ‘class or class of business ‘ consisting of occupations such as physician or attorney, and sometimes teacher ( Carr 2000:22 ) , to which a certain position may be attached. This should be regarded as distinct from the mundane usage of ‘professional ‘ as distinguished from ‘amateur ‘ which focuses on whether or non an person is paid ( REF-Carr? ) . The intent of sing some businesss as ‘professions ‘ differs harmonizing to different positions. Some respect it as a socially constructed construct, proposing it is a agency of continuing power and position with a certain group of people ( Locke et al. 2005:558 ) . Carr ( ? ? : ? ? ) suggests it refers to those businesss that are required to keep civil society ( wellness, justness and instruction ) . Others suggest that there are certain specifying features which mark out an business as carry throughing the standard for ‘profession ‘ ( Locke et al 2005:558 ; Christie 2003:845 ) . Whilst this diverseness of positions exists, there does look to be a general sense that those businesss that are classed as professions involve a degree of liberty to do determinations, a distinguishable cognition base or expertness, and some signifier of attention or service to society ( Carr 2000 ; Christie 2003 ; Goodson 2003 ; Locke et Al. 2005 ) . Professionalism itself may be possibly regarded as the manner in which we describe a profession in footings of its features in relation to these constructs ( Goodson 2003:126 ) . In kernel professionalism is concerned with sing the degree of liberty afforded to persons by an business and the nature of the professional cognition or expertness involved. In this manner, the averment referred to earlier, that the English National Curriculum is considered as a procedure of de-professionalisation, may be regarded as a belief that the degree of prescription involved is cut downing teacher liberty and altering the nature of the expertness required to make the occupation. As such, the distinguishable features of learning are more narrowly defined. Carr ( 2000:15 ) refers to such a decreased liberty and cognition base as ‘restricted professionalism ‘ . It is suggested that instruction is alone amongst the professions in footings of its balance between liberty and answerability ( Carr? ? ) . As Locke et Al ( 2005: 564 ) point out, there is a ‘tension ‘ between professional liberty and answerability. This alone answerability is related to the relationship between instruction and society. Education, or instead schooling, is basically concerned with ‘the sort of society we want to be ‘ ( White 2004:2 ) and is frequently related to the economic wellness of a state ( REF†¦ . ) . This is apparent in the claim that the ‘Curriculum for Excellence can play a important function ‘ in accomplishing the Scots Governments purpose ‘to make Scotland smarter, safer and stronger, wealthier and fairer, greener and healthier ‘ ( Scots Government 2008:3 ) . It is from this impression of schooling as helping, and potentially formative, society as a whole that it is suggested that schools and instructors are accountable in ways that other professions are non ( Carr 2000:44 ) . It is further suggested that instructors are besides more accountable to parents and must accept the legitimacy of the positions of ‘non-professionals ‘ in a manner that attorneies or physicians do non ( Carr 2003:64 ) . It may be as a consequence of this answerability to the province and parents that the dominant construct of instructor professionalism, in policy at least, has become that of the ‘competent instructor ‘ with a focal point on meeting prescribed criterions. ( Goodson 2003:127 ; Menter et al 2010:21 ) . Sing teacher professionalism in footings of criterions is argued to potentially take to a state of affairs in which the professional cognition base of instruction is strictly related to practical accomplishments, such as effectual communicating and the ability to pull off behavior ( Goodson 2003:130 ) . It is besides argued that such a position of instructor professionalism can take to ‘unreflective application of regulations ‘ ( Hegarty 2000:456 ) , instead than size uping and oppugning policy and course of study. It would look sensible to tie in a normative course of study with such a construct of instructor professionalism, as so Menter et Al. ( 2010:22 ) do. This would nevertheless, seem an deficient history of instructor professionalism to run into the demands of a course of study which gives teacher greater liberty of what to learn. Therefore, through concentrating on the particular issues which arise in relation to curriculum content choice, attending will be paid to theoretical accounts of professionalism which could possibly be regarded as more appropriate. Two thoughts will be addressed in relation to content choice. The first: the deductions of sing content choice as a pedagogical accomplishment ( REF†¦ ? ? ) with instructors pulling on, for illustration, cognition of kid development. The 2nd considers the deductions of sing course of study as a ‘selection of civilization ‘ ( Giroux 1980:228 ) , indicating to content choice as holding ethical deductions. Curriculum Content Selection Sing content choice as a pedagogical accomplishment would possibly reflect White ‘s ( 2004a:20 ) averment that instructors ‘ ‘expertise ‘ prevarications in ‘deciding what specific purposes and what student experiences best suit the peculiar kids ‘ . In this instance, instructors professional cognition may be regarded as wider than that of practical accomplishments, instead it involves pulling on pedagogical, capable specific cognition and cognition of kid development, to choose and order the content that makes up the course of study ( REF ) . The instructor is using their professional cognition in order to do professional opinions as to the content which will travel an person to the following phase of development. Clearly this points to the demand for some signifier of course of study purposes. As White ( 2004:6 ) points out, we can non sanely make up one's mind what to learn without mention to an purpose, an indicant as to what the following phase of development really is. Using such an apprehension to the CfE, we can see that the overall curricular purposes are set out in footings of the ‘four capacities ‘ – statements as to the type of individual the course of study seeks to develop ( Learning and Teaching Scotland 2010 ) . At a more elaborate degree, the ‘experiences and results†¦ describe the outlooks for larning and patterned advance for each of the eight course of study countries ‘ ( Learning and Teaching Scotland 2010 ) . The instructor, so, would look to hold autonomy in taking what they teach in order to accomplish the expected acquisition. The demand to do professional opinions of this nature would look to indicate to a construct of a more enhanced professionalism than a more normative course of study, and may indicate to such theoretical accounts as the ‘reflective instructor ‘ ( Moore 2004:4 ) . Such a theoretical account of professionalism is regarded as comprehending learning as affecting more than practical accomplishments. Rather the instructor reflects upon their schoolroom pattern, measuring their instruction, possibly pulling on their theoretical apprehension with a position to bettering and developing their instruction ( Moore 2004 ) . It could besides associate to the construct of ‘the asking instructor ‘ ( Menter et al. 2010:23 ) , in which instructors are regarded as research workers, pulling on observations in the schoolroom to inform their professional determinations in their planning. It is suggested that such a construct of the instructor is ‘very apposite in the context o f the Curriculum for Excellence ‘ ( Menter et al. 2010:23 ) , which seeks to give instructors greater liberty in course of study development. These theoretical accounts would surely look to widen the construct of instructor professionalism beyond that of the sensed technicism of the ‘competent ‘ instructor. As such they may supply suited theoretical accounts for instructors who are involved in the choice of course of study content, puting an accent on instructors ‘ pedagogical expertness. However, if we turn to the 2nd construct, an apprehension of course of study content as a ‘selection of civilization ‘ ( Giroux 1980:228 ) , understanding instructor professionalism in footings of pedagogical expertness may get down to look inadequate. Culture, in its broadest sense, may be regarded ‘as a whole manner of life ‘ , embracing all facets of society including the cognition, accomplishments and activities, such as athletics and ‘recreation ‘ , of that society ( Entwistle 1977:111 ) . However, if we regard instruction as being, in some manner, involved with ‘betterment ‘ ( Entwistle 1977:111 ) , schooling can non be concerned with all those things that make up a civilization. Rather, Entwistle ( 1977:111 ) , suggests that in schooling we select those facets of civilization which are regarded to be contributing to the ‘improvement of the person or group ‘ . This once more points to a consideration of the purposes of instruction: it is merely through an consciousness of what is regarded as ‘betterment ‘ , and hence, what we are taking to accomplish through instruction, that choice of content can sanely be carried out ( White 2004:6 ) . Related to this, cultural choice clearly besides implies a procedure of rating, separating between those things which we regard as ‘desirable or unwanted ‘ facets of civilization ( Entwistle 1977:110 ) . Therefore concerns about the choice of civilization which makes up the content of a course of study can possibly be regarded as originating both in relation to the purposes of the course of study and in the ratings of the comparative desirableness, or worth, of different cultural elements. Concerns that rise in relation to the purposes of the course of study are possibly best exemplified by the unfavorable judgments of a course of study whose purpose is, for illustration to increase employability accomplishments. Those who regard cognition acquisition as holding value in its ain right would see an instrumental attack to content choice as an poverty of instruction, restricting entree to many signifiers of civilization which may non hold direct instrumental value ( pulling on Carr et Al. 2006:17 ) . In this manner so, we can see that the choice of content is in some manner impacted upon by our beliefs about the intent of instruction, and as such sing choice of content as proficient accomplishment may be deficient. However, it is possibly in relation to the rating as to the comparative worth of facets of civilization that the most complex issues originate. It is in sing the relationship between cognition and power that cultural choice becomes debatable. This becomes apparent when we draw on Bourdieu ‘s ( 1986:106 ) construct of ‘cultural capital ‘ . Bourdieu ( 1986:106 ) suggests that different signifiers of ‘culture ‘ are invested with value which can be drawn on for pecuniary addition, or an addition in societal position. If we consider this in footings of ‘knowledge ‘ as a signifier of civilization, so acquisition of certain signifiers of cognition by an person can be utilised in bring forthing income and increasing societal position. For illustration, geting specific biological and medical cognition can enable one to derive both the income and position conferred upon a physician. However, it is non merely the acquisition of the cognition per Se. whi ch is valuable, but instead gaining institutional acknowledgment – in the signifier of an academic making – of possessing a peculiar signifier of civilization ( Bourdieu 1986:110 ) . In this sense, certain signifiers of cognition, certain signifiers of civilization, have greater value by virtuousness of being ‘institutionalised ‘ in the signifier of a making ( Bourdieu 1986:109 ) . This would propose hence, that schools are involved in both the transportation of signifiers of civilization which enable an person to derive economic capital or societal position, but besides in some manner specify what signifiers of civilization are of value. Such an averment is supported by Giroux ‘s ( 1980:228 ) statement that the civilization that is selected to organize the course of study becomes ‘legitimised ‘ by the really fact of its inclusion in the course of study. This construct can farther be seen in claims that the ‘traditional ‘ academic course of study is an elitist choice of civilization, giving value to signifiers of cognition associated with the in-between category ( REF! ) . It is the comparative value that become associated with different signifiers of cognition and different accomplishments that signifiers portion of what is termed ‘hidden course of study ‘ ( Ref ) . This is a mention to the values and thoughts that a school may non explicitly plan to learn, but which however are transmitted to students ( REF ) . It is suggested hence that the exclusion of an facet of civilization from the course of study communicates to pupils a belief about the comparative worth of this facet of civilization ( REF..exemplify? ) Moore ( 2004 ) provides an interesting illustration of this claim of elitism in cultural choice. Moore focuses on portraitures in movie of instructors who are regarded as ‘saviours and non-conformists ‘ ( Moore 2004:58 ) , such as ‘Ms Johnson ‘ in the movie Dangerous Minds. He argues that whilst the attack they take to instruction may be extraordinary, the content of that instruction is non. Moore ( 2004 ) contends that the cultural choice made by these instructors, of what he regards to be representative of in-between category values, ‘may be read as lending to and corroborating societal and cultural prejudices ‘ ( p.58 ) It is in this sense that Young ( 2006:734 ) argues that ‘social involvements are ever involved in course of study design ‘ , those with the power to choose what is included in the course of study have, to an extent, the power to legalize certain signifiers of cognition and certain patterns. It is suggested that through this procedure of advancing and legalizing in-between category civilization ( here we have the impression that a society consists of many ‘cultures ‘ ( ref ) ) , schools are implicated in intrenching inequalities of societal category ( REF ) . Such a claim requires closer consideration in order to understand the agencies by which cultural choice may be regarded to be implicated in affairs of societal justness. One manner in which it is suggested that this is the instance is that persons from a in-between category background have greater entree and exposure to the signifiers of cognition that are regarded as valuable by schools ( Reay 2006 ) . In this manner, Reay ( 2006 ) suggests, kids from in-between category backgrounds are at an advantage, able to pull on the cultural capital they already possess in order to execute good at schools, deriving institutionalized acknowledgment through academic makings, and therefore addition position in society. This would look to foreground a tenseness for those involved in choosing the content of a course of study. On the one manus, it is suggested that if schools do non supply the ‘high position cultural capital that academic and economic success requires ‘ so kids from working category backgrounds are potentially deprived of the ability to raise their societal position ( Anyon 2006:44 ) . However in making so, they are possibly complicit in reproducing prejudice as to what is regarded as legitimate and valuable cognition. It should be pointed out that this debatable history of cognition and cultural choice does non propose that ‘knowledge ‘ is incorrect or should non organize the footing of a course of study ( Young 2006 ) . Rather it suggests the demand to see the exact nature of the content we are taking to include, and significantly exclude, from the course of study. It suggests the demand for contemplation on our grounds for content choice, necessitating an consciousness of our ain prejudices we bring to the procedure ( Chan 2009: ? ? ) . From these observations, in which the choice of course of study content is regarded as holding societal deductions and is implicated in the transmittal of values, an apprehension of instructor professionalism which emphasises practical accomplishments or even pedagogical cognition possibly begins to look inadequate. Therefore the balance of this essay will see the impression that instruction is inherently ethical in its nature, and that teacher professionalism should therefore Centre upon the moral features of the profession ( Goodson 2003 ; Campbell 2003 ; Carr 2006 ) Carr ( 2006:172 ) argues that whilst all businesss are in some manner concerned with ethical issues, these by and large play a ‘regulative ‘ function – they indicate criterions for good pattern. However he suggests that this is non the instance with instruction, instead he suggests that ethical considerations are ‘constitutive ‘ of learning. This is possibly more clear in Campbell ‘s ( 2007:604 ) averment that: ‘It is far more ambitious to extricate the moralss of learning from the really procedure, pattern and content of teachingaˆÂ ¦ ‘ ( CHECK CONTEXT ) It would look that what is meant by this is that the determinations and actions taken by a instructor have ‘moral ‘ significance ( pulling on Campbell 2003:1 ) . By its really nature instruction is involved in organizing kids ‘s values and apprehension of the universe and as such is involved in conveying construct as to what is ‘right ‘ and ‘wrong ‘ ( REF ) . Further, as discussed earlier the determinations made potentially impact upon an persons accomplishment in schooling and therefore perchance impact their future chances. Following from this construct that issues of moralss are inbuilt into instruction, Campbell ( 2008:605 ) argues that ‘ethical codifications ‘ are deficient to turn to the issues faced by instructors. Rather she suggests that instructors requires an understanding by instructors of the complex moral issues they must turn to ( Campbell 2008:605 ) . It would look that within the Scots context there is acknowledgment of this. The ‘Standards for Initial Teacher Education ‘ in Scotland, which ‘specify what is required of a pupil instructor ‘ ( Christie 2003:847 ) , includes mention to ‘professional values and personal committedness ‘ ( Christie 2003:848 ) . There is a danger, Carr ( ? ? ? ) suggests, in bordering values as a competency or criterion, in that it would look to propose that the other facets of learning are ‘value-neutral ‘ . In this manner, the ethical nature of learning possibly can non be reduced to a competence or criterion. Rather Carr ( 2006:178 ) suggests that it is about instructors ‘taking moral issues and inquiries earnestly ‘ . It should be noted that this does non propose that instructors do non presently take moral and ethical considerations earnestly, Campbell ( 2003:2 ) argues that many instructors are cognizant of the moral deductions of their actions. However, Locke et Al. ( 2005:570 ) do suggest that when instructors are capable to high degrees of answerability it can take instructors ‘doing things right ‘ instead than ‘doing the right thing ‘ . Potentially, hence, the CfE ‘s focal point on greater liberty could supply greater flexibleness for instructors to do the determinations they regard to be ethically sound. At the same clip, by increasing instructors ‘ range for taking what to learn the ethical nature of learning possibly comes even more to the bow. It would look so, that in taking to give instructors greater liberty over the content of the course of study, the CfE both can be viewed as potentially heightening instructors ‘ professionalism as understood in footings of degrees of liberty. However, it besides seems to necessitate a consideration of the professional cognition base on which professionalism is based. The importance of pedagogical expertness and development is clearly of import and highlighted as so ( e.g. Scots Government 2009:4 ) . Yet, sing the complexness, and potentially value loaded nature of the cultural choice involved in choosing course of study content it would look of import to underscore the ethical nature of instructor professionalism. In kernel so, the greater liberty afforded to instructors to choose the content of the course of study by the CfE would surely look, as Menter et Al ( 2010:23 ) suggest, to indicate to a theoretical account of teacher professionalism in which instructors both reflect upon and develop their pattern. However in visible radiation of the basically ethical issues involved in content choice, it would look just to propose that instructors ‘ contemplations and determinations should pull non merely on theoretical and practical cognition, but must besides see the ethical grounds for taking to include, or non to include content in their instruction.

Latest Invention take Light Bulbs that Makes Use of Salmon desoxyribonucleic acid Researchers from the University of Connecticut recently unveiled their latest invention, which is a long-lasting LED light bulb that makes use of pink-orangedesoxyribonucleic acid. Scientists added twain different fluorescent colors to the desoxyribonucleic acid molecules, the sullys world spaced from each different(a) at a distance ranging from 2 to 10 nanometers.

Published in the journal temperament Communications, the study finds that short-wavelength UV exposure of the sponge-like polymer membranes in the presence of atomic number 8 allows the formation of ozone within the polymer matrix.The ozone induces oxidation of the polymer and chops longer polymer chains into much shorter segments, increasing the density of its summon. By controlling this densification, resulting in lesser cavities on the membrane muster, scientists throw a stylus found they atomic number 18 able to create a greatly enhanced sieve for molecular-level separation as these micro-cavities improve the talent of the membrane to selectively separate, to a signifi hatfult degree, molecules with unhomogeneous sizes , stay highly permeable for small molecules musical composition effectively blocking larger ones.The research from the University of Cambridges Cavendish Laboratory partly mirrors nature, as our planets ozone layer is created from oxygen hit by ultraviolet light irradiated from the sun.

The molecule, which the researchers call cyanostar, was developed in the lab of Amar flood, associate professor in the Department of Chemistry in the College of humanities and experiences. It is described in an article in the journal Nature Chemistry, scheduled for publication in August and available online. doctorial student Semin Lee is the lead origin of the article, A pentagonal cyanostar macrocycle with cyanostilbene CH donors binds anions and forms dialkylphosphate (3)rotaxanes.

Scientists from Julich and Berlin have developed a material for converting total heat and oxygen to water utilize a tenth of the typical core of platinum that was previously required.With the aid of state-of-the-art negatron microscopy, the researchers discovered that the function of the nanometre-scale throttle particles is decisively determined by their nonrepresentational shape and atomic structure. This discovery opens up new paths for further improving gass for energy agitateover and storage. The results have been promulgated in the current step up of the respected journal Nature Materials (DOI 10. 1038/nmat3668). Hydrogen- powered fuel cells be regarded as a clean alternative to conventional combustion engines, as, aside from electric energy, the provided substance produced during operation is water.At present, the slaying of heat content fuel cells is being hindered by the high material costs of platinum. biggish quantities of the expensive noble alloy argon still required for the electrodes in the fuel cells at which the chemical conversion processes take place. Without the catalytic effect of the platinum, it is not currently possible to achieve the necessary conversion range. As catalysis takes place at the surface of the platinum only, material can be saved and, simultaneously, the efficiency of the elec trodes ameliorate by victimization platinum nanoparticles, frankincense increasing the ratio of platinum surface to material required.Although the tiny particles argon more or less ten thousand times smaller than the diameter of a human hair, the surface argona of a kilogram of such particles is equivalent to that of several football palm. lifelessness more platinum can be saved by mixing it with other, less valuable metals, such as plate or copper. Scientists from Forschungszentrum Julich and Technische Universitat Berlin have succeeded in growing efficient metallic gas pedal particles for converting hydrogen and oxygen to water using only a tenth of the typical essence of platinum that was previously required.Researchers from Ulsan National set up of Science and Technology (UNIST), S. Korea, developed a smart, simple method to synthesize hierarchically nanoporous frame diddles of nanocrystalline metal oxides such as magnesium oxide and ceria by the thermal conversio n of well- knowing metal-organic frameworks (MOFs). The novel material developed by the UNIST research squad has exceptionally high carbonic acid gas adsorption capacity which could pave the air to save the Earth from CO2 pollution. Nanoporous materials represent of organic or inorganic frameworks with a regular, porous structure.Because of their uniform pore sizes they have the property of letting only certain(a) substances pass through, while blocking others. Nanoporous metal oxide materials argon ubiquitous in materials science because of their numerous potential applications in various areas, including adsorption, catalysis, energy conversion and storage, opto negatronics, and drug delivery. fleck synthetic strategies for the preparation of siliceous nanoporous materials are well-established, non-siliceous metal oxide-based nanoporous materials still present challenges.A description of the new research was produce (Web) on May 7 in the Journal of the American Chemical Soci ety.

Ionic fluent formulation improves herbicide Scientists in Poland and the US have re hypothesize the herbicide dicamba to reduce its environmental impact. The use of chemicals in agriculture is widespread, however, there are increasing concerns about their other environmental effects.Dicamba, used to control panopticleaf weeds in grain fields and grasslands, is known to enter the environment via water runoff and evaporation following its application. In an attempt to reduce its volatility, a group led by Robin Rogers, from the University of Alabama, and Juliusz Pernak, from Poznan University of Technology, has hypothecate dicamba as an noggin liquid. Ionic liquids are liquid salts, consisting of a cation and an anion. Deprotonated dicamba assumed the situation of anion a nd the team tested different cations to perk which conclave was near effective.The team formulated 28 new dicamba ionic liquids using hydrophobic cations that had surfactant or antimicrobial activities. We have always thought of ionic liquids as dual-acting that is, one can harmonize an diligent ingredient in some(prenominal) ions into a single salt, exaplins Rogers. By forming a hydrophobic ionic liquid, the water solubility of the herbicide was reduced. The new ionic liquids showed swallow volatility, increased thermal stability and improved efficacy in field tests over the parent dicamba.Not only are the ionic liquid forms desirable because of the potential for lower environmental impact, they actually work better, leading to lower application rates of the chemicals, Rogers adds. Bill Johnson from Purdue University, Indiana, US, an expert in the increment of weed management systems, comments that if a less volatile form of the herbicide can still provide the same level o f weed control, the concerns about off-site motility will be greatly reduced. He also says that this approach could be taken with other weak acid herbicides, such as 2,4-D (2,4-dichlorophenoxyacetic acid).The next step for Rogers and co-workers is to check into other cations with the dicamba anion to create a herbicide with other useful properties. Sustainable iron catalyst for clean hydrogenation 27 June 2013Emma Eley An world(prenominal) team of chemists has reported a clean and green way to perform one of the most important industrial reactions for pharmaceutic and petrochemical discount. Platinum group metals are currently the catalysts of choice for hydrogenations due to their high activity. However, they are also expensive, toxic and very rare.Now, in a joint be after between McGill University, Canada, and the RIKEN Institute, Japan, a polymer supported iron catalyst has demonstrated excellent performance as a hydrogenation catalyst in the most environmentally-friendly of reaction mediums water. Iron is superabundant and farther less toxic than the precious metal catalysts currently used, but its use in industry is limited by it rusting in the presence of oxygen and water. When rusted, iron nanoparticles stop acting as hydrogenation catalysts, explains project leader Audrey Moores from McGill University.The system we report solves this terminal point and makes iron active in water. Amphiphilic polymers, developed by Yasuhiro Uozumi at the RIKEN Institute, are used to protect the iron catalyst from being de pioneerd by water while still allowing reactants to reach the catalysts active site. After overcoming some synthetic difficulties involving the use of toxic iron pentacarbonyl, the team showed that their big-shouldered catalyst was tolerant to water and could be viewed as a realistic adversary to the platinum series metals. The authors demonstrate that the catalyst can be used in a flow system with little leaching, allowing for continuou s hydrogenation at the multi-gram scale, says Jianliang Xiao, a catalysis expert at the University of Liverpool, UK. As it stands now, the catalytic activity is still low that said, the study presents an excellent example of green chemistry in practice total atom-economic reducing in flow with an inexpensive and harmless iron catalyst.Future work from the team will focus on maturation and understanding the protective power of the polymer. We are also interested in maturation this catalyst for other industrially relevant reactions, says Moores. Titanium takes on HaberBosch process The deductive reasoning of ammonia under milder condition, using less energy and fewer resources, has moved a step closer. Scientists in Japan have created a trinuclear te polyhydride complex that can cleave the di newton bond and form newtonhydrogen bonds at ambient temperature and pressure without additional reducing agents or proton sources. 1 Nitrogen is the most abundant gas in our atmosphere, e ssential to life, and largely inert.Some microbes generate bioavailable nitrogen by reducing nitrogen to ammonia. Industrially, ammonia is produced via the HaberBosch process, which is so energy intensive that it consumes 1% of the energy generated globally. The process combines nitrogen and hydrogen over activated iron surfaces to generate ammonia for use as a fertiliser or as a chemical feedstock. This titanium complex could be part of the answer to producing cheaper fertiliser Science/AAAS The intrinsic inertness of nitrogen has made it contest to discover metal complexes that can two bind and activate it.By observational and computational studies, we determined that the dinitrogen reduction by a trinuclear titanium hydride complex proceeds sequentially through scission of a nitrogen molecule bonded to three titanium atoms in an end-on-side-on fashion, followed by NH bond formation, says study author Zhaomin Hou, of the RIKEN Center for Sustainable Resource Science, Japan. T he hydride ligands serve as the source of two electron and proton. Cleaving the NN bond and forming NH bonds instantaneously from a hydride complex has been seen only rarely, with some f the most prestigious work coming from Michael Fryzuk at the University of British Columbia, Canada, who has championed the hydride route to dinitrogen complexes. 2 The active sites of both major N2 reduction catalysts nitrogenases and the HaberBosch process have hydride species as their resting states, but in neither case is the detailed tool of hydrogen loss and nitrogen cleavage known, says Patrick Holland of the University of Rochester, US.The authors, he adds, conclusively determined the structures of many of the intermediates along the pathway, giving insight into possible structures and pathways of intermediates on the catalysts. Fryzuk, who wrote an accompanying perspective,3 says the melodic theme adds important aboriginal knowledge about potential childlike reactions such as cleav ing NN triple bonds and forming NH bonds, which are relevant to the HaberBosch process.He predicts it will change the way people think about N2 activation so that in the afterlife perhaps a soluble, suitably designed multi-metallic hydride complex will be able to both activate and functionalise molecular nitrogen productively to form ammonia or some other higher-value nitrogen containing material. However, there still challenges to over get it on to make this process practically useful, Hou says. But if booming the low temperature, low pressure synthesis of ammonia in smaller reactors is on the cards.Latest Invention Worlds First Battery Powered by Paper Sony has recently announced it managed to come up with a battery powered by newsprint. However, the whole process is more complex than simply using a standard root. The batteries developed by the Nipponese tech giant make use of enzymes in order to break down the glucose found in the cellulose of the base (which by the way is made of wood build fibers). It would be interesting to note that Sony was able to demonstrate its bio-battery. The demo took place at the Eco-Products exhibition in Tokyo.During the presentation the paper was placed into a mix of water and enzymes. After a couple of transactions the liquid started generating enough power to activate a small fan. After enzymes bust down the paper, they were left with sugar that was produced from cellulose. therefore they were able to process the sugar to produce hydrogen ions and electrons. The latter then went through an outer circuit to produce power. immix with oxygen in the air, the hydrogen ions were then able to create H2O. This is the same mechanism with which termites eat wood to get energy.Bio batteries are environmentally friendly and have great potential as they use no metals or harmful chemicals, explained Chisato Kitsukawa, a PR manager at Sony. Scientists use electron ink to write on graphene paper Nanoscale writing offers a reliab le way to record information at exceedingly high densities, making it a vivid tool for patterning nanostructures for a variety of electronic applications. In a recent study, scientists have demonstrated a simple barely effective way to write and remove on the nanoscale by using an electron bare to selectively break the carbon atoms in single-layer graphene.The researchers, Wei Zhang and Luise Theil Kuhn at the Technical University of Denmark in Roskilde, Denmark and Qiang Zhang and Meng-Qiang Zhao at Tsinghua University in Beijing, China, have published their study on using electron ink to write on graphene paper in a recent issue of Nanotechnology. The ability to record information has been directly correlated with the process of human refinement since ancient times, Wei Zhang told Phys. org. Paper and ink are the two essential factors to record history.Currently, information communication has proceeded onto an unprecedented scale. Nanoscale writing, which is essentially the habit of matter on the nanoscale, has already been wide explored. The current methods can be classified into two groups lithography (top down), which imprints a pre-made pattern on a substrate, but has restricted solving and self-assembly (bottom up), which manipulates atoms or molecules individually, but faces challenges with controllability.Herein, the researchers proposed a combination method based on both types of methods to overcome the difficulties of each, which they demonstrated on the thinnest paper in the world graphene. The rise of graphene calls for broad attention, Qiang Zhang said. One distinct characteristic is its flatness, which provides the perfective tense opportunity to be regarded as the thinnest paper. In order to directly write on this ultimate thin paper, the suitable ink must be found. At the small scale, typically nanoscale, the ink candidate ust pucker the qualification as both high-resolution writing and visualization function. Therefore, high-energ y electrons in a transmission electron microscope (TEM) are the best choice. The electron beam can be manipulated as ink for direct writing, but is by itself invisible. When an electron beam (green) writes on graphene paper, some of the carbon atoms in the graphene are kicked off, and external carbon atoms are deposited onto the hiatus bonds to form an irregular structure that appears as ink. Credit Wei Zhang, et al. 2013 IOP Publishing Ltd.As the researchers explain, the carbon atoms in graphene are untoughened to a variety of irradiation effects. Here, a 300 keV electron beam was used to break local carbon-carbon bonds in single-layer graphene. When the bonds break, carbon atoms are kicked off, resulting in dangling bonds that are free to attract new carbon species from the vacuum and on the graphene surface. These new amorphous carbon species become absorbed onto the dangling bonds to stabilize the edge, forming only along the scan direction of the electron beam.
