Towards industrial advanced front-junction n-type silicon solar cells Research Paper

Towards industrial advanced front-junction n-type silicon solar cells - Research Paper Example The justification of the project presented here is the need to develop better sources of energy (Yimao Wan et al. 1). The paper presents an analysis of the current trends in the field of engineering the solar cells. It takes a keen perspective on the development of the n-type front-junction monocyrstalline solar cells. It looks at the area variation and optimal output and the resistivity consideration that will yield potentially high output from the configuration. Moreover, production of solar cells undergoes a process better known as passivation. The cells are passivated using atmospheric pressure chemical vapor deposited (APCVD) Al2O3 together with the Plasma enhanced chemical Vapor Deposited (PECVD) SiNx. The expectation level of a potential 21.6% efficiency of output from the developed cells is put into consideration (Yimao Wan et al. 1). The ultimate point of developing a solar cell is to achieve a conversion of solar energy into electric power. The paper determines ways into which a voltage level of up to 664nV will be achieved since that will be an excellent combination of output from a cell that needs commercialization. Efficiency is also a matter that is dependent on the effective area size, and the paper projects a 2 * 2cm2 to be an excellent fit for such an application. In respect to coming up with an optimal approach to electric production from solar cells, the right combination are analyzed in an experiment and a discussion is presented in the paper. The resistivity variations used in the experimentation is a range from three to 10 Ohm.cm (Yimao Wan et al. 2). Larger area covered by a single cell has been analyzed to the extent of a 12.5 * 12.5 cm2. Dimensions are a critical aspect of design. It will determine the amount of light falling on the plate and hence the total output voltage. Research is going on to determine the best cell arrangement that optimally increases that the reception of light rays

Ethical Dimensions Of Medicine Research Paper Example | Topics and Well Written Essays - 1000 words

Ethical Dimensions Of Medicine - Research Paper Example There are different philosophical theories that can be used to describe or interpret the dfferent views concerning controversial subjects in medical ethics. David Hume lived in the 18th century and was a Scottish philosopher. Philosophical Theories on Issues in Medical Ethics Hume believed that reason, by itself cannot be presumed to be a motive of the will, but instead is subject to human passions(Mason and Laurie, 2010). He was of the opinion that in normal circumstances, moral distinctions are not the direct result of reason but of moral sentiments such as the emotions of blame or praise. Hume supported the view that there are intrinsic human sentiments such as the expression of vice or virtue; and also simulated actions like the human demonstration of justice. ones like the While some virtues and vices are natural, others, including justice, are artificial. According to Hume’s view, God formed the universe through different cycles; and He enabled man to be able to carry on his creative work. Moreover, He also gave free will to man. People, therefore, have the power to enact things that may not be a part of God’s will. The subject of medical ethics falls under this interpretation of what is right or wrong. The right to euthanasia, for instance, can be said to be an example of man’s ‘artificial’ justice which is not God-given but is the warped result man’s misuse of the free will that was extended to him by God. Immanuel Kant's theory, on the other hand, states that what guides the actions of man is 'rationality' (Mason and Laurie, 2010). According to Kant, human beings have the responsibility to perform what can be said to be 'reasonable' and not inconsistent. Kant stated that it was impractical to extend this responsibility in handling knowledge to the metaphysical arena. Kant stated that any moral obligation has to be applicable to all individuals in any circumstances and at any time. This means that any type of mor ality has to give evidence of a sound moral path in all circumstances and has to be useable to all people. From this view, a doctor’s care for his or her patient is basically a duty that has virtue. Immanuel Kant stated that, â€Å"only those actions which are performed for the sake of duty have moral worth† (Mason and Laurie, 2010). This definition alludes to a difference between inclination and duty. Kant’s views indicate a distinction between inclination and duty. If an individual has inclinations that support his or her duty, they have attained a higher moral development (Mason and Laurie, 2010). This means that Kant was of the view that it is a sacred duty to preserve life. However, if misfortune and hopelessness due to illness or manic depression life have removed all zest for life, the decision to euthanize has moral worth. Conversely, moral duty can be descriptive of preserving life in spite of adverse circumstances, not because of sentimental reasons, b ut because of a sense of duty. From the Kantian theory, one can surmise that the ‘rightness’ or ‘wrongness’ of controversial subjects in medical ethics such as euthanasia is dependent on the morality of the agent. For instance, if the motive of the child of a terminally ill patient who wishes to end his or her life is in line with his or her sense of duty to assist the patient, the child’s assisting of the patient to kill him oe herself becomes a moral act due to the fact that the child ignored his or her

Trends toward Western-style China and India Essay

Trends toward Western-style China and India - Essay Example marketers of today should understand that, to attract the large youth dominated markets, they must then provide the goods and services that are interesting to the youth and hence these goods and services must focus on music, fashion, technology and other factors that are influencing to the youth. Both companies from India and China emphasize on the importance of value differentiation in developing their competitive advantage strategies. The consumers in these emerging markets prefer value and are willing to consume more of the goods, which they believe are of quality, safe and have utility. In addition, these consumers are shifting upscale and ready to pay more for goods with integrity, reliability and desirable features that are made from high quality material and components (White, 2012). Therefore, it is evident that the old paradigm when consumers preferred price to all other factors is fading in these markets and consumers are shifting gears in their preference and tastes. Thus, this shift seems to be a new critical factor for marketers in in these emerging markets and a wake call to companies to produce new and better products meeting the consumers’ demands, taste and preferences, which ultimately would lead to customer brand loyalty. However, companies in the United States emphasize on the importance of a standardized marketing strategy, which involves marketing consumer goods in a uniform and consistent way across all the marketing mix. These companies view this strategy as the most influential and effective approach to developing competitive strategies. For instance, some companies in the United States standardize all aspects of their goods while others on the other hand standardize a few elements of their goods. However, whichever way or approach the companies use, they are able to make cost savings and ensure consistency of their goods globally (White, 2012). The consumption style of the West involves increased sensitivity to the different economic

The Importance of Entrepreneurship and Enterprise in the UK Case Study

The Importance of Entrepreneurship and Enterprise in the UK - Case Study Example As such, effective planning, control, organization, and coordination within a typical travel agency must be evident fro the efficiency and effectiveness of the services offered. The past studies and researchers on business management and entrepreneurship has extensively criticized the pure approach to formal strategic planning. Mintzberg (1978) argued that "contemporary prescription and normative techniques to business analysis and planning seem unable to address the complex reality of strategy formation". This was supported by Peters and Waterman (1982) when they concluded that formal strategic planning leads to "paralysis induced by analysis". Hills (1994) similarly found out that formal strategic planning was useful in the evaluation of opportunities, setting priorities, and implementation but not at the creative stage of identifying opportunities. In this regard, it appears that a good business strategy makes it a point to integrate and harmonize the goals, policies and actions of the organization into a tactical coherence in order to ensure and guarantee the success in the industry. The integration of the conservative and traditional management practices was observed in the ever-increasing complexity of the business environment. The technological advancements that characterizes the information era at present paved the way to the efficient conceptualization of more creative and effective business frameworks which when utilized by business companies will open more possibilities and better position in the competitive atmosphere in the industry. Hence, identifying the use of the control and the creative aspects in operating a business should be distinguished by a well-rounded entrepreneur. These will serve as the key to achieving the economic goals set by the by the entrepreneur for the overall success of the business since pure approach to operating a business venture will not exhaust the full potential of a particular business establishment. This paper aims to define what a "best entrepreneur" is, the qualities and characteristics of a good entrepreneur will be presented. The study chose two best entrepreneurs from United Kingdom, and they are Anita Riddick, the founder of The Body Shop and Joe Ashburner of Noonoo Designs. Entrepreneurship Entrepreneurship is valuable to the enterprise and also necessitates creativity as this aspect involves a constant search for new ways to compete in the market place. As all firms are always on the constant renewal mode, creative ideas must always be within reach. Indeed, the enterprise needs individuals who can couple a firm's capability and adapt to the rapid changes of the marketplace. This is not a role shouldered by the management alone, but must be shared with the participants as well, especially those working closely closest to the customers. Value-added entrepreneurial capability includes the ability and willingness to remain alert to the opportunities to the firm and to participate in the development of a solution. So as to make the most of each individual's contribution and productivity, it is probably more effective if each will be given an area of expertise. In this way, an individual can develop a capability in that arena, which will not only apply to individuals but also to their organizations. Network leadership must also enlist coalition attitudes so as to rekindle a sense of community. For an organization, this is a sense of belonging even if it is for a short period of time.

Nietzche watts lao-tzu Essay Example | Topics and Well Written Essays - 1750 words

Nietzche watts lao-tzu - Essay Example Plato viewed the role of education differently as compared with other philosopher who contributed on what education can give that distinguishes it distinctly from other experiences that can be acquired. Plato had a strong belief that education was peculiar in that it was able to prepare learners adequately for future life. This proposal by Plato has faced several rebellions by other philosophers such as Dewey and Rousseau who are considered the modern philosophers on education. Even though the modern philosophers have been opposed to the contribution of Plato, his arguments are still considered to be in context in the 21st century. Plato asserted that education has several concepts engraved in it that is essential in making an individual cope with the future given that the future is uncertain. Plato considered concepts such as reason, goodness, virtue, dialectics, ideas, sense of perception, metaphysics, motivation, art as considered to be a medium of instruction, and truth to be the guiding principles that one acquire through education and are of significant help in the future (Watts, 67). The fact that education according to Plato helps in preparing one for the future, Plato in this understanding came up with a philosophical statement that relates education, society and the individuals. In this case, Plato proposed that whereas the society is comprise of classes, the individuals in the society are comprises of faculties that are hinged on the kind of training they acquire through education. According to Plato, education is able to impact one or more of the above-mentioned concepts on the societal individuals and this reaches a critical level that they make the person fall in three of the following classes; rulers or the guardians, the warriors, and the workers and artisans (Watts, 77). He then related these classes to the three faculties that he proposed are in the society; the ruling class corresponded to the intellect faculty, the warriors occupy the facult y of feeling while the workers and the artisan are all camped in the faculty of desires and appetites. Nietzsche perspectives on Education Nietzsche on the other hand was a philosopher from German and was proficient in poetry, philology, composing, and analyzing culture through critique. Nietzsche in this regard wrote several materials that related to morality, contemporary culture, philosophy, religion and science. He also contributed on education and this is where we draw his perspectives on what his views were in relation to the achievement of education to an individual. Nietzsche just like Plato had a different view considering what education can achieve and in his opinion, he proposed the following. Nietzsche put it forth that education can achieve to make it possible to know the basic and original material of ones being. He said that through education one is able to realize the potentials that otherwise will remain completely unnoticed, through his literature on education Niet zsche asserted that without education, one is unable to know their worth and can be mistaken not to be worthy. He continued and said that education is a liberator in this context; it liberates one from ignorance, the ability to avoid vagueness, and irrationality. Through education explained Nietzsche, one is able to avoid equivocation of issues and will

Comparing hardy extract and the times article Essay Example for Free

Comparing hardy extract and the times article Essay In Far from the Madding Crowd, the author put great emphasis into using nature to describe the effects of the storm. The cleaving of the tree shows the storms power and ferocity. The author also uses the actions of the neighbouring wild life to show their reaction towards the storm. They are fearful of the storm, galloping about in the wildest maddest confusion. Their chaos is shown as they fling their heels and tails high into the air, their heads to earth. In The Times extract, most of the focus is on the uses of the visual and auditory senses to heighten the experience of the rollercoaster ride. It is easy to imagine the writers experience though the ways that she portrays every detail of the rollercoaster, from trundling away off the rollercoaster, to the hurtling through space, to the drawing back towards the platform. She describes the Tchika, tchika, thicka of the carriages clinking against each other as she approaches the zenith. You can relate to the way she feels as she trundles off, like an egg in a carton. When she reaches the pinnacle, she describes the merry-go-rounds no bigger than musical boxes, its coaster tracks like Meccano toys. The Times article also puts emphasis into the uses of the narrator and of the man behind her. The story is in first person narrative format. The narrator tells the story exactly how she sees it through her own eyes. She tells of every vision, sound, emotion and feeling. The narrator adds life to the experience, telling us her thoughts and fears, Oh my God! Had I got as high as that? The other character in this piece is the man sitting behind her on the rollercoaster. He dissolves all her confidence in an instance when he tells her, Thats the sc-a-a-a-riest seat. He adds depth to the ambience of the experience. In Far from the Madding Crowd, Hardy uses the contrast of light and dark to make the scene seem eerie. The light is described as intertwined undulating snakes of green embedded into the surrounding darkness. Another form of light is from the candle shining in Bathshebas bedroom. Also a blue light appeared in the zenith. The use of chiaroscuro is present here in presenting the dark form. The extract starts with light, but ends with black. In Far from the Madding Crowd, the use of language and sentence structure has depth and profundity to it. The dance of death is the surreal supernatural description of the storm, with skeleton shaped with blue fire for bones. The dead, flat blow reminds us the danger of the storm. The mailed army is a vision of a war against the elements. There are semantic clusters, like in death and battle. The writer uses superlatives to convey and craft his ideas, such as most extra,wildest maddest, and unparalleled. Hardy uses very dramatic vocabulary. He often uses personification, metaphors and similes. His sentence structure is strong, heaven opened then indeed. He has a strong use of discourse markers. In The Times article, the author uses vivid language that best describes her visions and feelings at the time. And then the horizon vanished. The story goes form a rather enjoyable and pleasant feeling to sudden chaos. The anxiety and fear of the writer, which was mildly present, totally changes once she begins to descend. The writer fears that she will faint, as she feels the safety bar will not hold her. There is a contrast between the use of language in the beginning and near the end. The sentence structure is normal, with roughly same amount of words in each sentence. She often uses personification, metaphors and similes to convey her experience. She has a strong use of discourse markers. The structure of Far from the Madding crowd is linear, ands follows on form beginning to middle to end in a very straightforward fashion. The structure of The Times piece is similar to that of Far from the Madding Crowd in the way that it has a linear structure, but the main difference is that there are four segments. The first segment is before the rollercoaster, and then before and leading up to the pinnacle, then the free fall and leading to the end, then actually ending and getting off the rollercoaster.

Separation of Amino Acids by Paper Chromatography

Separation of Amino Acids by Paper Chromatography Zarafath Jameel Table of Contents (Jump to) Introduction Applications of chromatography Types of Chromatography Paper chromatography Objectives Materials Methodology Results and Calculations The chromatogram The Rf calculated results Discussion Conclusion References Introduction Chromatography, Color written work. Chroma is a Greek roots prefix for color and graphy is a Greek roots postfix for composing. It is utilized to break down, recognize, clean measure the mixes. Chromatography is the physical division of a mixture into its individual parts The segments to be differentiated are disseminated between two stages, a stationary and versatile stage. A mixture which contains the solutes is divided into unadulterated parts by disregarding it the stationary stage (an insoluble material) to which the substances stick to fluctuating degrees. The portable stage, dissolvable is convey the solutes over the stationary stage. Partition focused around the distinctive communications of the mixes with the two stages. Substances that adhere firmly to the stationary stage move gradually, while those that stay approximately or dont stick at all move quickly. Chromatography might be a systematic strategy, in which the examiner takes in the number and nature of the parts in a little measure of a mixture, yet does not really confine them. A typical expository strategy is silica-gel dainty layer chromatography. Alternately it could be a preparative technique, in which the agent utilizes a vast amount of the mixture to get useable measures of every part. A typical preparative technique including the same stages is silica-gel segment chromatography. All chromatographic frameworks needs: A stationary stage (a robust, or a fluid upheld on a strong). a versatile stage (a fluid or a gas) sample particles (mixture for detachment) Applications of chromatography In any synthetic or bio-transforming industry, the need to partitioned and decontaminate an item from a complex mixture is a fundamental and imperative venture in the creation line. This partition of mixtures is helpful to us in different ways. As, Pharmaceutical industry utilizes chromatography to confine penicillin and different anti-toxins. Proteins can even be divided into amino acids. Chromatography is additionally utilized within wrongdoing scene examination for DNA and RNA sequencing. In numerous investigative studies to recognize obscure natural and inorganic mixes. Government research facilities used to weigh colors in nourishment and vegetables contained little measures of pesticides and herbicides. Types of Chromatography There are numerous types of chromatography, yet all structures take a shot at the same rule: Partition Chromatography which incorporates a fluid film covered in a dormant suitable backing. Adsorption Chromatography which incorporates finely separated robust working as an adsorbing surface they are partitioned finely to build their surface region. Ion Trade Chromatography (which is reversible step) which incorporates ionic gatherings (ionic means holding distinctive charges) which are joined to an inactive material; this technique is utilized within purging water for instance the opposition will be between the example (water considered portable stage additionally) the stationary stage specifically. gel Chromatography (additionally called sub-atomic sieving/Gel filtration/Gel penetration/Sub-atomic prohibition) which relies on upon a suspension of a polymer having a suitable pore size (like agar) is a vital strategy for a few examination sorts, for example, differentiating hormones, chemicals organic liquids; AGAR itself is a polymer with pores, so little particles will enter into the pores may leave just in the event that it discovered a bigger pore to enter in it Paper chromatography Paper chromatography is a logical strategy for differentiating and distinguishing both colored (e.g. colors) and boring (e.g. amino acids) mixtures. In paper chromatography, the stationary stage is an extremely uniform spongy paper. Cellulose (non polar) as paper sheets makes a perfect help medium where water is adsorbed to the cellulose filaments and structures the stationary hydrophilic stage. Cellulose is a polymer of the basic sugar, glucose. The key point about cellulose is that the polymer chains have -Goodness gatherings standing out all around them. The cellulose filaments draw in water vapor from the environment and in addition any water that was available when the paper was made. You can along these lines consider paper being cellulose strands with a meager layer of water particles bound to the surface. Non-polar particles in the mixture that you are attempting to particular will have little fascination for the water atoms joined to the cellulose, thus will invest a large portion of their time disintegrated in the moving dissolvable. Atoms like this will hence travel far up the paper conveyed by the dissolvable. They will have moderately high Rf values. Then again, polar particles will have a high fascination for the water atoms and significantly less for the non-polar dissolvable. They will consequently have a tendency to break down in the slim layer of water around the cellulose strands a great deal more than in the moving dissolvable. Objectives Identify the amino acids in unknown mixer, and calculate the Rf of each amino acids by paper chromatography. Materials Chromatography tank and lid Chromatography paper Capillary tubes Amino acid samples ( Arg, Trp, Tyr, Phe and unknown mixture of AA) Beaker BAW solvent – Butan-1-ol, acetic acid, and sterile water Ninhydrin Spray can Hair drier Latex gloves Methodology 10 Ãâ€" 20 centimeters chromatography paper was arranged by drawing a line 2 cm above from the bottom of the paper and little five imprints were made at comparable space interims alongside the line drawn. With particular slender tubes, arginine, phenylalanine, tyrosine, tryptophan and obscure amino corrosive mixture were tipped and were spotted on an imprint as they were named on the chromatograph paper, by touching the hairlike tubes on the chromatography paper and left them to dry and re-connected the examples a few times as the technique. After that chromatography paper was kept before the hair dryer to dry. When the BAW dissolvable of 100 ml was made by including Butan-1-ol, acidic corrosive, and sterile water in the 80:10:10 degrees. Fitting sum (around 1 cm) of BAW dissolvable was set into the chromatography tank. The chromatography paper was collapsed by the two side edges fit as a fiddle of barrel by stapling those edges close by without reaching each. After that the round and hollow chromatography paper was plunged equally into the BAW dissolvable and made to stand. Chromatography tank was shut by the cover and was left for 60 minutes. After that chromatography tank was revived and chromatography paper was expelled from the tank. The dissolvable line of the paper was checked right away and the chromatography paper was dried via hair drier. Following 05 minutes of drying, the entire paper was showered with ninhydrin by utilizing spread can. The spread paper was dried again utilizing hair drier. At last the separation went by specimen spots was stamped and separations were measured Results and Calculations The chromatogram Figure 01: The chromatogram The Rf calculated results Table 1. The results of Rf Sample Distance from star to Centre of spot (cm) Distance from start to solvent front Results / Rf Arginine 0.3 7.9 0.04 Tyrosine 1.9 7.9 0.24 Tryptophan 1.3 7.9 0.16 Phenylalanine 2 7.9 0.25 Unknown sample 0.3 7.9 0.04 1.1 7.9 0.13 Discussion In this analysis, pencil was utilized to draw the lines as opposed to pen in light of the fact that pen ink additionally moved by versatile stage and it may cause perusing mistake while taking the separation went by part from application point. At the point when setting the chromatography paper into chromatography tank the paper ought not to touch the divider of the tank, in the event that it does the paper will get polluted. The chromatogram is permitted to dry and is then showered with an answer of ninhydrin. Ninhydrin responds with amino acids to give colored mixes, primarily profound pink or purple shade. This chromatography system is likewise used to know the extremity of amino acids. In the event that an amino corrosive makes a high Rf worth means, that amino corrosive has less extremity; less extremity amino acids can without much of a stretch move towards the portable stage and shaped high Rf. High extremity amino acids dependably make less Rf esteem, it needs time to move towards the versatile stage. Wear gloves when taking care of Chromatography paper to abstain from touching the surface of the paper to be utilized for amino-corrosive chromatography in light of the fact that the skin contains amino acids the Chromatography paper as to abstain from saving amino acids from the fingers. On the off chance that it store aggravate the spots create. Regularly BAW dissolvable is use in Chromatography tank. It is a mixture segment of Butan-1-ol: Acetic corrosive: Water in a certain degree (60:15:25). Yet In this reasonable BAW mixture part of Butan-1-ol: Acetic corrosive: Water in a certain proportion (80:10:10) on the grounds that dissolvable of the BAW contain high measure of Butan-1-ol. It is cant break up in water. In this handy, utilized homogenous of the BAW result thusly change the degree of the contain parts. At the point when putting the chromatography paper into chromatography tank the paper was deliberately set ought not to touch the divider of the tank on the grounds that in the event that it touches the divider of the tank the paper will get defiled and the dissolvable ascend through the divider of the tank. The different amino acids are imperceptible. The acids might be envisioned by splashing the paper with a compound called ninhydrin. The chromatogram was permitted to dry then result of ninhydrin was spread on the chromatogram. Perception is Purple shade in light of the fact that ninhydrin responded with amino acids to give shaded mixes, essentially profound pink or violet color. Conclusion The Rf value of unknown mixture from this experiment was 0.04 and 0.13and it suggested the possibility to presence of two different amino acids such as arginine and tryptophan by having same Rf values (0.04 and 0.13). By the chromatography technique, identified the different amino acids in unknown mixers. References Ahuja, S.
