Recycling Composite Materials

Recycling Composite Materials Composite materials, known for their durability, high strength, excellent quality, low maintenance, and low weight, are widely being used in automotive, construction, transport, aerospace and renewable energy industries. Their use in  numerous  engineering applications is a result of the edge composites provides over traditional materials. Recycling and disposal of composite materials is an issue that is being increasingly addressed, as it should with any widely used material. Previously, there were very limited commercial recycling operations for mainstream composite materials due to technological and economic constraints but RD activities are on the rise. Recycling Fiberglass Fiberglass is a versatile material that provides  tangible  potential over conventional materials such as wood, aluminum, and steel. Fiberglass is produced by using less energy and is used in products which result in fewer carbon emissions. Fiberglass offers advantages of being light weight yet has high mechanical strength, impact resistant, is chemical, fire and corrosion resistant, and a good thermal and electrical insulator. Even though fiberglass is extremely useful for the reasons previously listed, an end of life solution is needed. Current FRP composites with thermoset resins do not biodegrade. For many applications where fiberglass is used, this is a good thing. However, in landfills, this is not.   Research has lead to methods such as grinding, incineration, and pyrolysis being used for recycling fiberglass. The recycled fiberglass finds its way in various industries and can be used in various end products. For instance, recycled fibers have been effective in reducing shrinkage in concrete thereby increasing its durability. This concrete can be used best in freezing temperate zones for concrete floors, pavements, sidewalks, and curbs. Other uses for recycled fiberglass include being used as a filler in resin, which can increase  mechanical  properties in certain applications. Recycled fiberglass has also found its use together with other products such as recycled tire products, plastic wood products, asphalt, roofing tar and cast polymer  countertops. Recycling Carbon Fiber Carbon fiber composite materials are ten times stronger than steel and eight times that of aluminum, along with being much lighter than both materials. Carbon fiber composites have found their way into the manufacturing of aircraft and spacecraft parts, automobile springs, golf club shafts, racing car bodies, fishing rods, and more. With the current annual worldwide carbon fiber consumption being at 30,000 tons, most waste goes to the landfill. Research has been conducted to extract the high-value carbon fiber from end-of-life components and from manufacturing scrap, with the goal to use them for creating other carbon fiber composites. Recycled carbon fibers are used in bulk molding compounds for smaller, nonload-bearing components, as a sheet-molding compound and as recycled materials in load-bearing shell structures. The recycled carbon fiber is also finding uses in phone cases, laptop shells and even water bottle cages for bicycles. Future of Recycling Composite Materials Composite materials are preferred for many engineering applications because of its durability and superior strength. Proper waste disposal and recycling at the end of the useful life of composite materials is necessary.  Many current and future waste management and environmental legislation will mandate engineering materials to be properly recovered and recycled, from products such as automobiles, wind turbines, and aircraft that have lived their useful life. Although many technologies have been developed such as mechanical recycling, thermal recycling, and chemical recycling; they are on the brink of being fully commercialized. Extensive research and development are being done to develop better recyclable composites and recycling technologies for composite materials. This will contribute to the sustainable development of composites industry.

The IOM Future of Nursing report related to the nursing workforce Essay

The IOM Future of Nursing report related to the nursing workforce - Essay Example Importance of the IOM â€Å"Future of Nursing† Report Nurses practice in various settings such as schools, retail health clinics, battlefields, public health centers, long-term care facilities, homes, and hospitals. They have differing levels of competencies and education in the entire nursing sector. The committee put into consideration nurses at all levels including their settings, education levels, and roles in an attempt to envision the profession’s future (Institute of Medicine of the National Academies, 2011). The Future of Nursing report is very important since it addresses some of issues facing nurses such as differing education and competency levels. Several barriers obstruct the nurses from responding effectively to the rapidly transforming health settings as well as the evolving health care system. The barriers have to be overcome to make sure that nurses are in a good position to advance health and lead change. Apart from seeking to remove these barriers, the report recommends the improvement of the nursing education system. This is because patients’ needs are becoming more sophisticated and thus, the nurses have to attain requisite competencies in order to deliver care that is of high quality (Institute of Medicine of the National Academies, 2011). ... Some of the main issues raised by the report are that nurses should practice to the greatest extent considering their training and eductaion; and that the education system that is in place to train nurses should be improved so as to encourage higher training and education of nurses for better servieces(Institute of Medicine of the National Academies, 2011). In this respect, the report recommends that varous boards, government bodies, accrediting societies and healthcare organizations should support nurses during their residency once they have successfully completed the prerequisite courses or when they are taking new areas related to clinical pratice. In addition, the report recommends that the proportion of nurses holding a baccalaureate degree should be inreased from 50% to 80% and the number of nurses with a doctorate dregree doubled by 2020 (Institute of Medicine of the National Academies, 2011). In order to achieve this goal, academic nurse leaders should join forces and partner with other organizations to establish a workforce that is responsive to the diverse healthcare needs of the population. Furthermore, the report notes that nurses should participate fully in redisigning the country’s health care. Yet again, the report notes that better information collection and infrustructure is valuable if effective policies have to be made and the workforce properly planned. The Intent of the Future of Nursing: Campaign for Action The Future of Nursing: Campaign for Action represents an exceptional initiative to tackle the elevated demands for care by using all the talents, experience, skills, and knowledge of nurses. The main aim of the Campaign for Action is to manage the implementation of the IOM landmark report recommendations. The campaign

Teamwork. Organization Structure and Design, and Organisation Culture Essay

Teamwork. Organization Structure and Design, and Organisation Culture - Essay Example 3). Employees have a lot of impact on the tendency of an organization to be innovative and competitive (Bakker and Schaufeli, 2009, p. 147) which imparts need for the leaders to keep the employees motivated. Different organizations have different strategies of developing teamwork and also have different organization structures and designs, and organizational cultures. Factors that control these elements include but are not limited to the nature and scope of business, and the socioeconomic and political conditions prevalent in the areas where the business is established. There is no hard and fast rule which can be applied to all organizations. While there are numerous theories of teamwork, organization structure and design, and organizational culture, yet they have to be customized to suit the individualistic needs of different organizations. This paper draws a comparison and contrast between the teamwork, organization structure and design, and organizational culture of two organizati ons; Biogenia and Sleepeasy. Comparison of approaches to teamwork and teamworking Teamwork is the work accomplished by interdependent employees in a group to achieve a goal of mutual concern (Parker and Wall, 1998). Teamwork encourages employees to collaborate with one another (Salas and Gelfand, 2012) and allows employees to be more included in the decision-making process (Mat and Razak, n.d., p. 218). Teamwork is essential to the success of both non-profit and profit-oriented organizations (Rapur and Rapur, n.d.). â€Å"As â€Å"no man is an island,† the positive effects of productive teamwork can energize an entire organization, just as the negative effects of a lack of teamwork can cripple an organization† (Slechta, n.d.). Biogenia places a lot of emphasis on the development of teamwork among the employees. This is achieved by interchanging their roles which is an essential component of teamwork (Griffin, Patterson, and West, 2001, p. 537; Tannenbaum et al, 1996). This has a two-way effect on the employees that increases their tendency to be better team members. Firstly, every employee gets an opportunity to work in a different position for some time during which, the employee gains exposure to the job responsibilities associated with that position so that whenever required, other employees can be invited to do certain tasks that are different from the tasks they normally do in their respective positions. This provides Biogenia to incorporate multi-tasking in its employees which in the long run is in the best interest of Biogenia as well as its employees as they would be equipped with diverse experiences. â€Å"Moving to multi-skilled teams will alter the range and style of working† (Acas, n.d.). Secondly, when an employee gets to work in some other position for some time, it enables that employee to gain an insight into the potential issues and challenges encountered by the employee who regularly serves in that position. This not only increases the employees’ knowledge of the challenges faced by all departments of the organization, but also increases their tendency to cooperate with employees from other departments in the hour of need as they know that the cause is genuine as they personally had had an opportunity to experience the issues while they served in other departments for some time. â€Å"To perform the task better, individuals depend on knowledge from other units or departments†

Statistical analysis of data Statistics Project Example | Topics and Well Written Essays - 500 words

Statistical analysis of data - Statistics Project Example In this dataset we can find out the average emission of the pollutants over the years for different activities and can report which activity has the most notorious impact on the environment. As we have analysed Constructions and construction works for civil engineering has the highest average emission of greenhouse gases, heavy metals and acid rain precursors compared to others while specialised construction works has the highest average emission of other pollutants. For the year 2009 and for other years also we can find out which construction activity has created the maximum and minimum pollution and thus which is sustainable and which is not. Since 2005 to 2009 we can see that a specialised construction service has created the maximum pollution and thus is less sustainable while the Buildings and building construction works has created the minimum pollution over the years and thus is more sustainable than others. From 2000 to 2004 activity of constructions and construction works fo r civil engineering has created the maximum pollution. Time series forecasting of overall emission for three activities can be given for the next 5 or 10 years using minitab or other statistical tools like R or SAS. In excel we can do moving average and trend analysis like linear trend, quadratic trend etc for the data. In the given data, it has been noticed that the data for year 2000 and 2001 is exactly same across all categories. Data on other manufacturing sectors and industries like automobile industry, chemical industry, fertilizer industry etc and their emissions of pollutants like greenhouse gases can also be collected for time period say 2000 to 2013 so as to compare it with the construction activity emissions of the same. Time series analysis can be done in tools like minitab to forecast each sector emission of greenhouse gases for next five years. Time series forecast like moving average, blended moving average, trend analysis can be done in excel

Analyze George Orwell's, Shooting An Elephant through the eyes of the Essay

Analyze George Orwell's, Shooting An Elephant through the eyes of the author of the Moral Instinct Steven Pinker - Essay Example This has never been put across more effectively as in the George Orwell’s essay, shooting the elephant. The author is forced by the general expectation to do what he does not believe in. He takes us through his ordeal so that we can understand the reasoning we often undergo in order to make decisions that seem conflicting in our lives. It’s not just the content of our moral judgments that is often questionable, but the way we arrive at them. We like to think that when we have a conviction, there are good reasons that drove us to adopt it (Steve 1).Orwell goes to a great length to try to justify decisions he made in this essay. A great lesson can be learned from his work. The author hated being a police officer. This was because he was secretly against imperialism which he was a part of. He was against the oppression of the Burmese people. He says he hated the job bitterly than he could clearly put across in the essay. He lives a miserable life, since he hates his empire and cannot voice his concerns. The people he seems to care about are against him and they make his life impossible. This is a tough way to live. He hated the conditions of prisoners huddled together and the sight of the oppressed. What keeps him on the job? Orwell tries to draw an emotion from us. He tries to make us fit his shoes so we can see how tough it was for him to quit his job. He was uneducated and young and could not seek employment elsewhere. He would have chosen to quit this job which did not stand his moral grounds rather than stay in unhappy employment. This builds on the fact that people seek justifications for actions they do in order to feel accepted. This is not the only incident that the author is faced with such a situation. He is called upon to kill an elephant which had gone rogue. He describes the pressure he felt. â€Å"And suddenly I realized that I should have to shoot the elephant after all. The people expected it of me and I had got to do it; I could fe el their two thousand wills pressing me forward, irresistibly.† (Orwell 1). What made the matter worse was that the elephant was a tame one. He considered shooting a working an elephant a very serious offence comparable only to destroying a piece of machinery a decision which should have been avoided at all costs. With these strong convictions the reader is almost led to believe that Orwell was not going to kill the elephant. However despite being so against the action of taking the creatures life he goes ahead and does it. In trying to justify his action he claims that he would have looked like a fool. He did in order just to save face. This according to the reader is not a good enough reason but to him it is a reassurance that what he did was right. The oppressor is often viewed to be above the oppressed. Orwell in this situation proclaims that this is not always the case. He realizes that tyranny only jeopardizes the freedom of the oppressor. The tyrant is viewed by the opp ressed as being heartless and has to live up to these expectations. The tyrant is not allowed to show any signs of affection or weakness despite them being a part of human nature. One has to spend his life trying to impress the natives and so in every crisis he has got to do what the natives expect. The general expectation was that the white man was not supposed to be afraid of anything. Thoughts of what the people would think in case something went wrong during the
