Relevance of Philosophy Essay Example

Relevance of Philosophy Essay In this essay the challenge is to shown the relevance of philosophy to 21st century manufacturing. As philosophy is not a new concept there is a wide and defervesce range of ideas (on everything that existed and does not yet exist). The people who study philosophy and deal with such matters must have at one stage put forward some thoughts on manufacturing and even engineering in general. Philosophy comes from the Greek for love of wisdom, giving us two important starting points: love (or passion) and wisdom (knowledge, understanding). Philosophy sometimes seems to be pursued without passion as if it were a technical subject like mathematics. Philosophy must come from some passion for the ultimate goal to be achieved: a reliable, accurate understanding ourselves and our world. Many think philosophy an idle, academic pursuit, never amounting to anything of practical value. The works of ancient Greek philosophers, ask the same questions which philosophers ask today. Doesnt this mean that philosophy never gets anywhere and never accomplishes anything? Philosophy is relevant as it makes us think about where we have come from, where we are at present and where we are going to in the future. The study of philosophy is usually conducted in one of two different ways: the systematic/ topical method and the historical/ biographical method. Both of these have their strengths and weaknesses and it is often easier to avoid focusing on one to the exclusions of the other, at least whenever possible. There are many different areas of philosophy which have relevance to manufacturing and will have relevance in the future.

Some areas of study in philosophy are logic, ethics and epistemology (knowledge, ways of knowing) to name but a few important that are relevant to manufacturing. In this essay I hope to discover the link and the importance of philosophy in relation to manufacturing in the 21st century. Main body The main areas in which manufacturing are influenced by philosophy is ethics, logic and epistemology. Logic  is the study of  reasoning. Logic is used in most intellectual activities, but is studied primarily in the disciplines of philosophy,  mathematics engineering, and  computer science. Logic examines general forms which  arguments  may take which forms are valid, and which are fallacies. It is a type of  critical thinking. The field of ethics (or moral philosophy) involves systematizing, defending, and recommending concepts of right and wrong behaviour. Philosophers today usually divide ethical theories into three general subject areas: met ethics, normative ethics, and applied ethics Knowledge is about how things work and why they work and that’s what engineering and the sciences set out to do. Manufacturing is a by product of knowledge. These areas can be viewed from many philosophical points. And the different areas which have relevance to manufacturing can be put into three main branches and several sub branches. These main three are Epistemology, Logic and Ethics and some sub branches of the three main relevant branches to manufacturing, economic, technological mathematic, social and rational argument. The relevance of philosophy to manufacturing goes back long before the industrial revolution and even further back then the roman’s but to the first philosopher Pythagoras. These topics will be discussed in more detail later. Ethics or moral philosophy This is the branch of philosophy which seeks to address questions about morality that is, about concepts such as good and bad, right and wrong, justice and virtue. Anyone who has read Aristotle’s Ethics and has read modern moral philosophy must realise the great contrasts between them. The concepts which are prominent among the moderns seem to be lacking, far in the background, in Aristotle. Most noticeably, the term ‘moral’ itself, which we have by direct inheritance from Aristotle, just doesn’t seem to fit in its modern sense into an account of Aristotelian ethics. Aristotle distinguishes virtues as moral and intellectual. This area of philosophy is a broad area of study and is very relevant to everybody in normal day life. We take for granted the morals we live by and the morals of others, this too can be true for ethical practices that take place in manufacturing. Ethics are used by every company and business as bases for running their organisation such as fair trade, quality of product and quality of working environment. Some examples of ethics that show how important it is to consumers that companies have morals include: Fair Trade In the case of fair trade ethics has changed the way trade is done and the way people are treated in the process. In the past number of years important social changes have occurred with ethics an example of simple ethic in fair trade would be the production of coffee beans. Companies in recent years have begun to buy fairly bought produce where the producers benefit. As most of the producers are poor farmers. But because of the moral changes that have taken place in the past twenty years things have improved before the change in attitude the companies bought the product at low prices for big plantation owners and the poor suffered because of it. Quality of Product The role of ethics in quality of product we can take a very recent example and it is very much manufacturing example that of Toyota with the stricken of the accelerator pedal. The company is calling back thousands of cars for repair; this will cost a lot of money. And why its being done well the company has a moral obligation to produce a product fit for use. The ethics behind leaving defective products in us by consumers it could cause many incidences and maybe fatalities. The ethics that Toyota will abide by. Will cost the company a lot of money but may save the company on the long run. Companies who didn’t solve their problems. i. e. the car company Lancia who had a rust problem, which crippled the company in the end. And Toyota could fall a similar fate and begun bankrupt if not carful. It can be said that it is not ethics that is making Toyota recall all these cars but money. That unfortunately that is a pessimistic view and one would hope that Toyota is doing it for the right reasons over the value of reputation and money. Quality of Working Environment Quality of working environment is the final scenario. There have been many changes in the way people work and the place in which they work in as most working environment can be very dangerous places. Since the start of the industrial revolution high fatalities have occured due to machines with little or no safety aspects, have been recorded and it was due to companies disregarding safety of workers to make high profits. It may not be as big an issue today in the western world but to poorer more undeveloped countries where workers are still being neglected-ethics will play a role to improve he working environment and show manufacturing in a better light, now and in the future. Ethics is the bases of why good judgment is made so as to maintain and improve society. In a manufacturing sense morals can be a corner stone in changing work practices in industry. It can be a tool for progress in the future. The moral obligation to all is to be just and right, the phrase â€Å"Do no harm† can be an important to manufacturing and life in ge neral. Thomas Hobbes had stresses the importance of peace and security. With ethics in mind he said; there is no place for industry, because the fruit thereof is uncertain: and consequently no culture of the earth; no navigation, nor use of the commodities that may be imported by sea; no commodious building; no instruments of moving and removing such things as require much force; no knowledge of the face of the earth; no account of time; no arts; no letters; no society† And then follows the description of life under such conditions made so by repeated quotation that I refrain from quoting it still again. Where morals prevail peace can be seen. Peace and security, however, including secure property rights and the attendant opportunities to create and accumulate wealth, permit â€Å"commodious living†, which is Hobbes’s term for economic development. In the three examples it can be seen where ethics has played a part in changing the mind set of people and companies in the past few decades. It may not be ethics which was the catalyst for these changes but it is the way things are changing for the better. Hobbes had a point even if it was a bit extreme; there is room for good if people give it a chance and do the right thing. Logic Logic is the study of reasoning. And reasoning typically focuses on what makes reasoning efficient or inefficient, appropriate or inappropriate. Logic is the corner stone of science and mathematics which in turn play a vital role in engineering. It is one of the oldest areas of philosophy going back to Aristotle. Along with Aristotle some key figures in the study of logic were Bertrand Russell, Charles Sanders Peirce and Immanuel Kant. These men made many points on the area of logic As like ethics, logic is a wide area of study. This is important to us in our every day existence. Logic is what we use to solve from our most basic problems to the kind of problems that change the world socially, economically, technologically and mathematically to name but a few ways. Logic can be broken down into two parts inductive reasoning and deductive reasoning. Inductive reasoning is where a set of facts are given and from those facts a conclusion can be got from it an example of this in is a jigsaw puzzle all the parts are there but the pieces must be put together to see the full picture. On the other hand deductive reasoning is quiet different while inductive reasoning all the pieces are to be seen at once deductive reasoning gets it answer on a logical sequence of events, example of deductive reasoning is where a problem is set out but there is only one piece of information to work on and from that another piece of information is discovered until a logical sequence is established and an answer is reached like a detective solves a crime. Logic is the tool to solve any problem or argument which may arise by using the types of reasoning. And with this in mind logic will play a part in the future of manufacturing because without the use of logic the problems of the future won’t be solved and manufacturing will not progress. Epistemology Philosophy is largely based on known knowledge and epistemology is a study of knowledge. Descartes defines knowledge in terms of doubt. While distinguishing rigorous knowledge and lesser grades of conviction, Descartes writes: â€Å"I distinguish the two as follows: there is conviction when there remains some reason which might lead us to doubt, but knowledge is conviction based on a reason so strong that it can never be shaken by any stronger reason. † [Stanford, 2010] According to Bertrand Russell in regards to Epistemology, he says â€Å"we could be familiar with objects in two ways: knowledge by acquaintance and knowledge by description. He also thought that we could only be acquainted with our own sense data and that everything else we had to know through reasoning. It set out to answer â€Å"what distinguishes true (adequate)  knowledge  from false (inadequate) knowledge? This question translates into issues of scientific methodology: how can one develop theories or models that are better than competing theories. There is many areas which knowledge can be broken down into these main areas are Ratio nalism, Scepticism Rational Knowledge Rationalism Mathematics and geometry are examples of abstract truths which are known with certainty, even though the physical illustrations of these truths may vary. An early example was the Greek philosopher Plato who stated that ideas have an existence independent of human minds. These independently-existing ideas are the only reality in the universe since they are absolute and unchanging. Valid knowledge comes then when the mind grasps these ideas. Another famous philosopher was the Frenchman Rene Descartes who went through a period of scepticism in his life and then came to the conclusion that only ideas which were clear and distinct to the mind represented valid knowledge â€Å"Objections to Rationalism: . There is no agreement among philosophers or cultures about so-called self-evident ideas. Supposedly self-evident ideas have often been rejected at later times in history. 2. Self-evident ideas provide no knowledge about the world. Though sense experience may not be certain, it provides us with information which is as reliable as we need. The fact that a belief is not absolutely certain should not disqualify it for knowledge. Why not say t hat something is  known  as long as there is no good reason to doubt it? Of course, that might mean that occasionally we would have to admit that what we thought we knew was something that we really didnt know. So what? † [tamu, 2010] Scepticism This is the view that questions whether valid or reliable knowledge is ever attainable by a human being. Some sceptics stated that nothing can be known. Other sceptics stated that they did not know whether knowledge was possible; they suspended judgment on the issue. Some of the common examples used by sceptics are the illusions and deceptions of our senses. Others point to the complexity of any experience and ask how you can know what is the essence or real nature of the things you are experiencing. Empiricism This is the view that valid knowledge comes only through the five senses. Aristotle held the view that whatever was in the mind was first in the senses. Rene Descartes  (1596-1650) He claims, unless we know first whether our belief itself is justified. To determine whether our beliefs are justified, we have to be able to trace them back to a statement, belief, or proposition that cannot be doubted. Such a proposition could provide the firm foundation on which all subsequent beliefs could be grounded; it would guarantee that all subsequent claims based on it would be true. In order to identify an ultimate principle of truth on which all other knowledge can be based, Descartes develops a method that suspends our confidence in what we have been taught, what our senses tell us, what we think is obviousin short, in regard to everything we know. In order to determine whether there is anything we can know with certainty, he says that we first have to doubt everything we know. Such a radical doubt might not seem reasonable, and Descartes certainly does not mean that we  really  should doubt everything. What he suggests is that, in order to see if there is some belief that cannot be doubted, we should temporarily pretend that everything we know is questionable. Since sense experience is sometimes deceiving, it is obvious to Descartes that  a posteriori  claims (e. g. , that this milk tastes sour or that suit is dark blue) cannot be the basis for claims of knowledge. We do not know that what we experience through our senses is true; at least, we are not certain of it. So the best thing to do is to doubt our senses. Likewise, we cannot be sure that we really have bodies or that our experience of the world in general can be trusted; after all, we might be dreaming the whole thing. Next, we cannot even be sure that mathematical propositions such as 2+3=5 or that triangles always have three sides are true because some evil power might be deceiving us to think such things, when it is possible that even propositions that seem evident to us as true might themselves be really false. But even if an evil genie deceives us about all other beliefs, there is one belief that we cannot be mistaken about, and that is that we are thinking. Even to doubt this is to affirm it. Thinking proves that we exist (at least as minds or thinking things, regardless of whether we have bodies). The body is not an essential part of the self because we can doubt its existence in a way that we cannot doubt the existence of the mind. We have a great inclination to believe that there are physical objects that are external to the mind. But since only those objects known in terms of mathematical propertiesnot those imagined by use of the sensescan be known clearly and distinctly, the only knowledge we can have of such objects is in terms of mathematical, quantifiable physics. The only real knowledge we can have, then, is of things understood as functions of laws of physics. The objects we  see  are not the objects we  know, because what we know is intelligible only in terms of the clarity and precision of the formulae of physics. Information provided by the senses cannot therefore be the basis of knowledge. [tamu, 2010] Kant Immanuel Kant (1724-1804) was a German philosopher who attempted to combine rationalism and empiricism. It is called the form and matter epistemology. A statue can have a form such as Abraham Lincoln and a matter such as marble; you need both a form and a matter to have a statue. So in knowledge you need a form, which are categories of the mind,  and matter which are the data of sensatio ns. You need both of these to have knowledge. It is similar to wearing rose-colored glasses. You have visual sensations and they are coloured by the glasses. Of course with the mind you cannot take of your glasses. Knowledge is an incredibility powerful tool which has created great nations and pushed the boundaries of science and technology to new areas. The quotation from Sir Francis Bacon (1561-1626) said that â€Å"knowledge is power† and that has always been the case since the dawn of civilisation, knowledge has been a part of every major advancement. Knowledge has a big part to play in manufacturing, it is an integral part of all advancement without the constant need for knowledge through research and other means it would be impossible to make major achievement. The different areas which have been discussed can be seen as different way we can go about solving difficult situation and problems. Manufacturing will need to conform to these different methods of thinking in the future. Conclusion Philosophy can be shown to have many areas some of which have been covered throughout this essay. The areas which have been covered are relevant to manufacturing in ways that show philosophy as a key component to running a lucrative and sustainable operating line. Philosophy has a lot of points to make; its relevance to manufacturing can be used as a tool for advancement in the future in areas such as Ethics * Companies treatment of small producers * Quality of products produced for consumers * The working environment Ethics has a role to play in changing these for the better and will have a maintaining a standard in future productions, especially in third world countries where companies have taken advantage of their workers yet do not pay a moral price. Logic The study of reasoning logic can be found at the core of engineering and manufacturing in general. It is a corner stone in which there are couple of ways of resolving a problem. The two main types are * Inductive * Deductive These two methods of solving apply to certain manufacturing dilemmas depending on the individual situation. A logical sequence of steps to gain the solution in which a process i. e. a production line is established by taking the correct logical sequence for the line to work effectively. Logic has a vital role in the way manufacturing process are carried out, without which there would be ciaos, void of efficiency, continuity and general order. Epistemology Epistemology is the study of knowledge and the ways of knowing. It schools of thought from which theories have sprung can be divided in the categories. * Rationalism The view of using absolute truth which is known with certainty is rationalism. Breaking knowledge down into its simplified core elements to revel the truth. * Scepticism This is seen where a theory is put forward and is then questioned. Many theorists maintain that some knowledge can never been known in its entirety or factually. It is questioning until a hypothesis or theory is validated to their satisfaction. * Empiricism Using the five senses to gain knowledge, most natural form of collection of information as we do it every day unknowingly. In the future the ideas and views of philosophy will have a significant part to play in manufacturing and engineering in general. As it has had an important role to play in the past. Manufacturing can be broken down into many different areas and this is due to philosophy and the thinking required by the different schools of thought in the related areas. As all area have a knock on effect on each other, i. e. logic can change the methodology significantly. We now realise the importance of philosophy in every day manufacturing although it might not appear obvious but under the surface of manufacturing processes is detrimental to efficient, cost effective, and ethic practices in the work place.

[tamu, 2010] Kant Immanuel Kant (1724-1804) was a German philosopher who attempted to combine rationalism and empiricism. It is called the form and matter epistemology. A statue can have a form such as Abraham Lincoln and a matter such as marble; you need both a form and a matter to have a statue. So in knowledge you need a form, which are categories of the mind,  and matter which are the data of sensatio ns. You need both of these to have knowledge. It is similar to wearing rose-colored glasses. You have visual sensations and they are coloured by the glasses. Of course with the mind you cannot take of your glasses. Knowledge is an incredibility powerful tool which has created great nations and pushed the boundaries of science and technology to new areas. The quotation from Sir Francis Bacon (1561-1626) said that â€Å"knowledge is power† and that has always been the case since the dawn of civilisation, knowledge has been a part of every major advancement. Knowledge has a big part to play in manufacturing, it is an integral part of all advancement without the constant need for knowledge through research and other means it would be impossible to make major achievement. The different areas which have been discussed can be seen as different way we can go about solving difficult situation and problems. Manufacturing will need to conform to these different methods of thinking in the future. Conclusion Philosophy can be shown to have many areas some of which have been covered throughout this essay. The areas which have been covered are relevant to manufacturing in ways that show philosophy as a key component to running a lucrative and sustainable operating line. Philosophy has a lot of points to make; its relevance to manufacturing can be used as a tool for advancement in the future in areas such as Ethics * Companies treatment of small producers * Quality of products produced for consumers * The working environment Ethics has a role to play in changing these for the better and will have a maintaining a standard in future productions, especially in third world countries where companies have taken advantage of their workers yet do not pay a moral price. Logic The study of reasoning logic can be found at the core of engineering and manufacturing in general. It is a corner stone in which there are couple of ways of resolving a problem. The two main types are * Inductive * Deductive These two methods of solving apply to certain manufacturing dilemmas depending on the individual situation. A logical sequence of steps to gain the solution in which a process i. e. a production line is established by taking the correct logical sequence for the line to work effectively. Logic has a vital role in the way manufacturing process are carried out, without which there would be ciaos, void of efficiency, continuity and general order. Epistemology Epistemology is the study of knowledge and the ways of knowing. It schools of thought from which theories have sprung can be divided in the categories. * Rationalism The view of using absolute truth which is known with certainty is rationalism. Breaking knowledge down into its simplified core elements to revel the truth. * Scepticism This is seen where a theory is put forward and is then questioned. Many theorists maintain that some knowledge can never been known in its entirety or factually. It is questioning until a hypothesis or theory is validated to their satisfaction. * Empiricism Using the five senses to gain knowledge, most natural form of collection of information as we do it every day unknowingly. In the future the ideas and views of philosophy will have a significant part to play in manufacturing and engineering in general. As it has had an important role to play in the past. Manufacturing can be broken down into many different areas and this is due to philosophy and the thinking required by the different schools of thought in the related areas. As all area have a knock on effect on each other, i. e. logic can change the methodology significantly. We now realise the importance of philosophy in every day manufacturing although it might not appear obvious but under the surface of manufacturing processes is detrimental to efficient, cost effective, and ethic practices in the work place.

The Bet

The Bet "The Bet" By Anton Chekhov The debate among about life imprisonment virus's capital punishment has been fought long and hard. This argument takes place here in this story where two men are having a lively discussion about which is more humane, life imprisonment or capital punishment. The one who chooses life imprisonment is the lawyer. The banker is against this and chooses death. The banker is so sure that no one would lose their life to imprisonment rather then end it all quickly. The banker, so confident, makes the bet with the lawyer staking two million rubles that he couldn't sacrifice his freedom for his belief and stay confined by himself for fifteen years.The banker being so confident thinks no one would lose fifteen years of his or her life for so much money. In the beginning the banker disagrees with the people who say that the death penalty is out of date.Prisoners per 100,000 population

Arguments for anti-feminism Essay Example | Topics and Well Written Essays - 1000 words

Arguments for anti-feminism - Essay Example Are women deprived of rights in society as pointed out in lieu of the feminist view or are women appropriately designated with responsibilities fit for their nature compared to the status of men? It is evident that feminism is a concept motivated by the quest for social justice of individuals who believe that women are disadvantaged in society. I consider feminism as both an intellectual commitment and a political movement that seeks equality for women and the end of sexism in all forms. As James characterizes it, â€Å"feminism is grounded on the belief that women are deprived of certain rights and oppressed by comparison with men, and that their oppression is in some way illegitimate or unjustified†, (276). Crow adds that, â€Å"injustices to women are referred to as the imposition of weak roles to women from roles at home and at work to the bigger part of societal functions†, (1). I will prove in this discussion that the feminist claim, that is, women are denied equal rights by being secondary to men is unsound. As Okin makes the point, â€Å"subordination of women in the context of a family is nothing but a role which could be fulfilled as a role in the family†, (68). I can clearly see that housekeeping functions are allocated to women because a family is a relationship built from the cooperation of the partners. Male partners should handle the financial burden since they are more productive and their biological structure provides for the competitive work advantage. With the role of income generation left to the responsibility of men, housekeeping in general should just be naturally assigned to women. In addition, it could easily be argued that men should be given the responsibility to have better compensation â€Å"because of their role in the labor market† (Bergmann 112). Men deserve to get the top spot in the market of jobs and be remunerate d better relative to women due to their abilities. It is the goal of feminism as well to eliminate the culture in

Modernism Visual Comical Strips Research Paper Example | Topics and Well Written Essays - 750 words

Modernism Visual Comical Strips - Research Paper Example The essay "Modernism Visual Comical Strips" discovers modernism and visual comical strips. The modernism arts focused on freedom and individuality as evidence from Pablo Picasso’s art works. Modernism art, therefore, saw the emergence of some new media especially photography thus it emerged during the eras of history of photography and this explains why history records the photographers of 19th century. Modernism also marked the beginning of the new art forms like animation, assemblage, cinematography and even the avant-garde art, including the earliest conceptual art forms and the same style was used on comic strips as the same themes are portrayed in the modernism cartoons and other visual comedy. Style and setting of modernism comical strips used backgrounds that showed how the society evolved to become civilized. In most modernism comedies, the artists used black and white backgrounds to show an evolving society unlike the postmodernist artists that have used technology to affect the backgrounds to the desired colors. On the other hand, most of the modernism comedies centered on war and how servants served their masters. Moreover, modernism visual comedy shows the activities of social organization, architecture, and economic situations in the modernist era that become outdated as industrial revolution took over the world. Post modernism art came about after the emergence of modernism arts and as such, contradicted the aspects of the modernism art. Post modernism in visual art includes general aspects.

Bio-based Polymers and Their Future Trends: Article Review

Bio-based Polymers and Their Future Trends: Article Review The selected article, Current progress on bio-based polymers and their future trends[1], provides insight into the present tendencies, technological advancements, and the prospective utilisation of bio-based polymers obtained with renewable means. A wide domain of bio-based polymers are analysed in this article specifically focusing on its production, its characteristics and its potential in commercialisation. The review also measures the subsequent challenges whilst introducing these polymers for appliance. Consequently, the analysis of the review article pertains generally to specialists such as scientists possessing a background knowledge of bio-based polymers, to entrepreneurs who intend to commercialise these bio-based polymers due to their increase in allure as a renewable and environmentally friendly product and perhaps to enthusiasts. Part of this reasoning is due to the extensive use of chemical jargon and its passive and scientific articulation. Subsequently, the review art icle was difficult to comprehend as a scientifically sound reader. The discipline ideally suited for the review article is a combination of organic chemistry, polymer chemistry. Organic chemistry and polymer chemistry are both a chemistry subdiscipline where the former deals with the study of organic materials[2], matter formed with carbon atoms, and where the latter deals with the study of synthetic polymers[3]. The article examines the bio-based polymers, hence falling into the categories of organic chemistry and polymer chemistry. Additional disciplines can be related to this article but may seem ambiguous such as materials science which briefly covers the study of polymers[4] and industrial engineering[5] which examines the cost effectiveness of the production of these bio-based polymers. Therefore, article should be categorised as a discipline of organic chemistry as it focuses on bio-based polymers. The association concerning the discipline of organic chemistry and the review article from the journal Progress in Biomaterials relates thoroughly within. As stated in the description[6], this journal examines the preparation and characteristics of biomaterials in vitro and in vivo and assesses its compatibility in areas such as tissue engineering, drug delivery and implants and regenerative medicine. The editorial board regarding this journal is of an international standard where people from universities universally gather in order to publish and review this journal. Hence this journal is open accessed and peer reviewed published under the SpringerOpen brand and also approved by the Ministry of Science, Research and Technology, obtaining a high credible standard[7]. The journal, published by one of the many leading academic services[8], is therefore associated with the discipline of organic and polymer chemistry. The purpose of the review is to assess a variety of bio-based polymers of their production, characteristics, their effective future applications in our society and its difficulties. The review article investigates and assesses as much as ten bio-based polymers, each with diverse scrutinies, and therefore cellulose[9] will be briefly discussed as an example of what is reported as it is also associated with the primary article[10] that will be compared from the review articled. In this review article, cellulose, reported to be one of the largest bio-based polymer produced[11], is attained through the two methods: sulfite and pre-hydrolysis kraft pulping and has a ninety seven percent purity rate[12]. Cellulose is a rigid polymer and is highly tensile relative to other bio-based polymers. This causes processing problems and therefore is plasticised, mixing itself with other polymers, to soften itself for ease of use[13]. Subsequently, there are three main branches of which cellulosoic p olymers are classified under after chemical modification for applications: cellulose esters, cellulose ethers and regenerated cellulose. Each of these have difference uses: cellulose esters are mainly utilised for film and fiber, cellulose ethers are used in food and personal care and regenerated cellulose are used for disposables, textiles and fabrics[14]. The main drawback to the production of this renewable source is the low yields compared to its high expense.[15] The immense amount of professional research expressed into this review article accounts for the 159 references. Many of these references are primary articles which are peer reviewed whilst there are also some that are also review articles. Most of these references are linked to reputable academic services such as Oxford Academic and Science Direct. The sources of the review article are generally recent as most of them are from the 21st Century. The selected primary article, Cellulose Extraction from Palm Kernel Cake Using Liquid Phase Oxidation[16], is an experimental report that investigates the production of cellulose via its extraction from palm kernel cake with the method of liquid phase oxidation. Specifically this primary article highlights the optimization of this process where the yield of cellulose would increase as a variable changed such as the ration of hydrogen peroxide and the hot water treatment. As a result a theoretical optimal point was discovered. The investigations of this primary article is significant to the review article as it contributes through the production of cellulose, one of the many bio-based polymers discussed in the review article. This helps the audience to understand how cellulose is produced, providing insight on its benefits and drawbacks. While both articles relate to cellulose, the nature and purpose can be distinguishable. The primary article contains experimental data and methods which aimed to optimise the yield of cellulose whereas the review article aimed to provide information to an audience, gathering its data from a variety of sources.

Global Problems Such As Climate Change Greenhouse Effect Engineering Essay

Nowadays people are faced with many planetary jobs, such as clime alteration, nursery consequence, acid rains, air and H2O pollution, etc. One of the major jobs is air pollution. Air contain waste gases from cars, such as oxides of sulfur, N, C monoxide, which combine in air with H2O or other atoms, organizing unsafe compounds, destructing ozone bed and precipitating with acerb rains. Many solutions are proposed presents, such as utilizing environmentally friendly fuels, change the auto or engine design. One of possible solutions is auto mass decrease. For illustration, â€Å" each 100 g of decrease of auto mass consequences in salvaging 0.3 liters of fuel per 100 kilometer, which equals to 0.6 – 0.7 kilogram of CO2 † ( Steeluniversity.org ) But how can the mass decrease be implemented? Harmonizing to the equation, mass depends on the volume and the denseness of the stuff: As it is seen from the equation auto mass can be reduced by taking the stuff with lower denseness or by cut downing the volume of auto parts. In footings of the first solution steel remains to be the most suited stuff because of it ‘s mechanical belongingss. Steel has satisfied formability, articulation ability and output strength. Customers are happy with steel. Almost all autos are made from steels and the industry has all agencies and conditions for it. However, unstained steel is rather expensive and coating must be used. There are besides some alternate stuffs with lower denseness – Ti ( I?=4.52 ) , aluminum ( I?=2.71 ) , glass ( I?=2.55-3.55 ) , Mg ( 1.71 ) , composite ( 1.55-1.93 ) , polymer ( 0.9-1.7 ) , cloths ( 0.8-0.9 ) , white pine ( 0.51 ) . ( Istochnic ) . But they can non be used by several grounds: Cost – auto doors made of Ti, Mg, aluminum can be really expensive, so that clients will non accept these autos. Lower mechanical belongingss. Cars may non go through clang trials Poor formability Joining troubles -it can be hard to fall in such auto outer door panel with the body-in-white. Extremist alterations of the whole fabrication procedure may be required The alteration of the stuff may ensue in the alteration of assembly fixtures, organizing dies, etc. Further probes are necessary Some of these stuffs are already used in luxury autos, such as Lotus. ( Istochnik ) . But for household autos it seems to be impropriate. Hence, steel is chosen for the auto door outer panel. To cut down auto mass another parametric quantity can be changed – V ( volume of the constituent – in our instance the volume of door ) . We can non extinguish this constituent due to safety demands. We can non change the surface of the door, because it can do the alterations of the whole building. That is why the merely possible thing we can make is to understate the thickness of the door which seems to be the best option. However, we should utilize another type of steel to follow with all safety and design standards. Purposes to cut down the auto outer door panel mass at least by 25 % take the thickness of the door carry out trials on formability, articulation ability, corrosion opposition, dent and oil-canning trials take the steel and coating method Calculate weight and cost nest eggs When planing auto door the most important belongingss should be considered are: Joinability – the ability of steel to fall in, depend on the chemical science and strength ( Istochnik I change ) Formability – ability to accept the desirable signifier deue to fictile distortion. With the addition of strength formability decreases ( Change and Istochnik ) Corrosion opposition – bar of the destructive onslaught by the environment ( alteration and Istochnik ) Dent opposition – the ability of the stuff to defy local distortions. Small defects can be caused by rocks ( Change and Istochnik ) Furthermore trials are needed to be carried out in order to look into the belongingss of chosen stuff. Dent and Oil-canning trials Dent trial and Oil-canning trials are required to find the thickness and the output strength of auto door panel. The minimal values of this parametric quantities following with this demands should be found. Difference between as-received output and the concluding output strength.

Date from the dent and oil-canning trials for each thickness Figure 1. Yield Strength against curvature for each thickness What parameters does the dent trial depend on? What parameters does the warp trial depend on? Which strength is needed for each thickness? Corrosion opposition The life-time warrant for auto door panel is 12 old ages. Several factors contribute to the corrosion opposition, including the stuff chosen. Stainless steel has first-class opposition to corrosion, but it will be really expensive to bring forth auto from this stuff. Uncoated steel will non last for 12 old ages harmonizing to rust procedure. So, the coated steel is the most cost effectual manner of bettering corrosion opposition of an uncoated merchandise. There are several types of coatings, viz. : pigment coating, Sn coating, Zn coating, Cr coating and polymer coating. Paint, Sn, polymer, Cr can give aesthetic consequence but one time scratched it will non protect steel from the corrosion because they act merely like a barrier. Serious environmental concerns and high cost can be deal with in the instance of polymers and Cr. Furthermore, extra coating may be needed to give the appropriate coating and surface required by clients and marketing co-workers. That is why Zn seems to be the best coating stuff. Even if scratched it will give the steel. It gives an first-class protection due to sacrificial mechanism. However, extra bed is needed to obtained coloring material that consumers need. Industry criterion corrosion trial is carried out in order to find the thickness of Zn coating and technique for using Zn coating. First Zn coated sheet 150Ãâ€"100 nanometer is treated with Zn phosphate, premier with catodic electrocoat, spray with white based coat and finish with clear coat. Scribe the painted steel – one diagonal abrasion through the coatings to the steel. The sheets are subjected to the 80 rhythms. – one per twenty-four hours. This corresponds to 3.4 old ages of exposure to existent conditions. Measurement showed how many millimeter of pigment next to the Scribe was removed. Due to the experiments day of the month the most effectual type of surfacing are HD galvanised and HD galvannealed. Cold rolled steels showed the worst corrosion opposition.Coating typeCoating weight, g*m2Average scribe weirdo, millimeterElectrogalvanized steel30 2.7Electrogalvanized steel+Zn rich primer40 2.8Hot dip galvanized steel45 2.6Electrogalvanized steel60 2.1Electrogalvanize steel70 1.6Hot dip galvanized steel67 1.7Hot dip galvanized steel107 1.4 The size of the auto door is 700Ãâ€"1000 millimeter. So, the country of the door is: S= 700*1000=700 000 mm2 It is known that the average loss of pigment is 0.01 % after 12 old ages. The country of paint loss can be calculated as: Spain loss=700 000*0.01/100=70 mm2 If this happen due to one abrasion, it may be possible to cipher the mean scribe weirdo after these 12 old ages. However, it is assumed that horizontal Scribe is non governed by the length of the abrasion. Scribe creep12 years=70/10=7 millimeter Similarly, Scribe creep1 year= 7 / 12 = 0.583 millimeter Scribe creep3.4 twelvemonth = 0.583 * 3.4 = 1.9822 a†°? 2 millimeter Using the above secret plan it is possible to happen the thinnest coating matching to 2mm scribe weirdo. The thinnest coating is 60 g. per mm2 or 8.4 A µm. The surface coating and the cost depend on the type of surfacing. The average cost for 60 g/mm2 coating is the undermentioned: 1.27 for galvanneal steel ; 1.3 for dip galvanized and 1.33 for electrogalvanized. Similarly the surface finish index is 1, 0.95 and 0.9, severally. Hot dip galvanized coating was chosen for this instance, because this coating showed itself better during corrosion trial and it has the mean values of the cost and surface finish index. Formability During formability trial a steel foliage is analyzing at particular imperativeness. This trial demonstrates the location of major strains in auto door panel. The angle parts of the panel a most likely to tear during forming. To prove these corners Forming Limit Diagram is applied. It is seen from the trial that the location of the secret plan on the Diagram depends on several factors, such as strength, type of the coat and oil for lubrication. To put the points to the safe country the undermentioned parametric quantities were chosen: Thickness t = 0.6 millimeter As-received yield-strength 290 Mpa Coating – hot dip galvinised Lubricant – Oil 2 The as-received strength alters the work indurating advocate which affects stretching of the steel sheet. In our instance the minimal work indurating advocate was found to be 0.2. We besides do n't take into history the R value since deep drawing is non utilize for auto door panel. Joinability There several types of fall ining techniques, such as adhesive bonding, concentrating and welding. Adhesive bonding is non normally used for auto door because it is technically complicated and economically unbeneficial. Riveting is used for some parts of autos but this method is impracticable for doors, since it would impact the visual aspect of the vehicle. In this instance welding seems to be the most appropriative. Steels are easy welded together, what is widely used in industry. Among the great sum of welding techniques ( electron beam welding, optical maser welding, seam welding, metal inert gas welding, opposition topographic point welding, discharge welding, clash welding ) opposition topographic point welding is the best pick for auto door outer panel. This technique is accessible and easy. the thickness of the steel sheet and the type of surfacing can impact fall ining procedure. That is why joinability trials should be carried out to look into if steel sheets with chosen coatings can be welded together. During the trial the following values were determined: Thickness, T millimeter 0.6 As-formed output strength, MPa 210 Load, kN 1.9 Welding current, kA 8.0 Welding clip, rhythms 8 Hold clip, rhythms 10 Coating Hot-dip galvanized Electrode life 2000 dyer's rockets 1 rhythm = 0.02 s What is the minimal and maximal current that produces acceptable dyer's rockets? Which is the minimal and maximal electrode force? What is the minimal and maximal dyer's rocket rate? Determine this inquiries when there is no coating Steel choice Now we have to take the steel class. Harmonizing to our consequences, we were proposed 6 types of steel: The BH220 Bake Hard steel was chosen.

How temperature will effect the speed in which the enzyme Catalase will react with Hydrogen Peroxide Essays

How temperature will effect the speed in which the enzyme Catalase will react with Hydrogen Peroxide Essays How temperature will effect the speed in which the enzyme Catalase will react with Hydrogen Peroxide Paper How temperature will effect the speed in which the enzyme Catalase will react with Hydrogen Peroxide Paper Individual enzymes are named by adding ase to the name of the substrate with which they react. The enzyme that controls urea decomposition is called urease; those that control protein hydrolyses are known as proteinases. Some enzymes, such as the proteinases trypsin and pepsin, retain the names used before this nomenclature was adopted. * They are all proteins * They are specific in their action, one enzyme speeding up one reaction only. * They work within only a narrow range of acidity or alkalinity. * Heat alters enzymes so they work at different rates. At certain high temperatures enzymes denature. * They can be used over and over again. * They all require water before being able to function. * Living cells are the only producers of enzymes. * The enzyme molecule is only temporarily changed during its action and can be used repeatedly. Large quantities of enzymes are not necessary. * They work within a narrow range of temperature. Enzymes are typical catalysts: they are capable of increasing the rate of reaction without being consumed in the process. Some enzymes, such as pepsin and trypsin, which bring about the digestion of meat, control many different reactions, whereas others, such as urease, are extremely specific and may accelerate only one reaction. Still others release energy to make the heart beat and the lungs expand and contract. Many facilitate the conversion of sugar and foods into the various substances the body requires for tissue-building, the replacement of blood cells, and the release of chemical energy to move muscles. Pepsin, trypsin, and some other enzymes possess, in addition, the peculiar property known as autocatalysis, which permits them to cause their own formation from an inert precursor called zymogen. As a consequence, these enzymes may be reproduced in a test tube. Source: Encarta 1998 Enzymes are extraordinarily efficient. Minute quantities of an enzyme can accomplish at low temperatures what would require violent reagents and high temperatures by ordinary chemical means. About 30 g of pure crystalline pepsin, for example, would be capable of digesting nearly 2 metric tons of egg white in a few hours. The kinetics of enzyme reactions differ from those of simple inorganic reactions. Each enzyme is selectively specific for the substance in which it causes a reaction and is most effective at a temperature peculiar to it. Although an increase in temperature may accelerate a reaction, enzymes are unstable when heated. Many enzymes require the presence of another ion or a molecule called a cofactor, in order to function. As a rule, enzymes do not attack living cells. As soon as a cell dies it is rapidly digested by enzymes that break down protein. The resistance of the living cell is due to the enzymes inability to pass through the membrane of the cell as long as the cell lives. When the cell dies, its membrane becomes permeable, and the enzyme can then enter the cell and destroy the protein within it. Some cells also contain enzyme inhibitors, known as antienzymes, which prevent the action of an enzyme upon a substrate Enzyme Controlled Reactions Enzymes are usually given a similar name to that of the substrate but ending in ase. The reaction has two arrows because the reaction is reversible. If there is more maltose than glucose, the reaction will go from left to right and the other way round. How do enzymes work? Molecules are constantly moving around and bumping into each other. When a substrate molecule bumps into a molecule of the correct enzyme, it fits into a depression on the surface of the enzyme molecule. The depression is called the active site. The reaction then takes place and the molecules of product leave the site, freeing it for another substrate molecule. The active site of a particular molecule has a specific shape into which only one kind of substrate will fit. The substrate fits into the active site rather like a key to a lock. This is why enzymes are specific in their action. When an enzyme is altered by heat, the shape of the active site is changed so that the substrate no longer fits. A change in pH has a similar effect. Preliminary Test We carried out a preliminary test on a smaller scale of the final experiment. We put hydrogen peroxide and liver together and measured the time taken for 10cm3 of oxygen to be given off. Liver was used because it is a source of catalase that is the catalyst we needed to speed this reaction up. We used the same apparatus as this final experiment and placed both reactants into the water bath. Once the reactants had achieved the desired temperature we then mixed them together, while keeping them in the bath. We then started the timer and inserted the bung immediately after mixing the two reactants. Once 10cm3 of oxygen had been given off we stopped the timer and took a reading.

How to Use Conjunctions As Far As, Since, and Even Though

How to Use Conjunctions As Far As, Since, and Even Though How to Use Conjunctions: As Far As, Since, and Even Though We use conjunctions (e.g., and or but) to build grammatical sentences, which in turn allows us to express ourselves clearly. Every conjunction has its own meaning though, so it’s a good idea to learn a few more! In this post, we take a closer look at three conjunctions that could help in your academic writing: â€Å"as far as,† â€Å"since† and â€Å"even though.† As Far As (To the Degree That) Used as a conjunction, â€Å"as far as† means â€Å"to the degree or extent that.† It therefore qualifies statements that apply only under certain conditions. The phrases like â€Å"as far as we know,† for instance, signals that something is based on incomplete information: The experiment poses no risk as far as we know. Here, â€Å"as far as† suggests the sentence is true to the best of our understanding. However, it leaves open the possibility that it is based on imperfect knowledge. Because â€Å"as far as† is a subordinating conjunction when used like this, it always joins a dependent clause (â€Å"as far as we know†) to an independent clause (â€Å"The experiment poses no risk†). Since (Time and Justification) Also a subordinating conjunction, â€Å"since† has two distinct uses. The first is to specify that something happened after a particular point in time: Since learning to dance, I’ve felt more graceful. In this case, â€Å"since† shows that the speaker started feeling this way only after learning to dance. The second meaning is to introduce a reason or justification for something (making it a synonym for â€Å"because†): Since we are interested in how people perceive retail experiences, we have adopted a qualitative research approach. Here, the word â€Å"since† joins a clause about the reason for picking a research approach to the main clause about the approach chosen. Even Though (Despite the Fact That) The term â€Å"even though† is used to introduce contrast in a sentence, like saying â€Å"despite the fact that†: Even though he was completely deaf from around 1820, Beethoven began work on his Ninth Symphony in 1822. The difference between â€Å"even though† and â€Å"though† is simply that â€Å"even though† is more emphatic. We therefore use â€Å"even though† when introducing a particularly surprising or unexpected contrast.

The 17th and 18th centuries were a time of great political change in Research Paper

The 17th and 18th centuries were a time of great political change in Europe - Research Paper Example To begin with, Hobbes being a scholar, his main aim was to place politics on a scientific grip, hence employing a strict logical method to his work. In contrast, Machiavelli having worked as one of the civil servants of Florentine Republic drew his conclusions, after observing how people behaved instead of how they should behave in an intangible and hypothetical world2. It is this methodology difference, which leads to differing political views of these two authors. Hobbes, writing Leviathan immediately after the end of civil war and unfruitful tries at republicanism in Europe, held less estimation of the nature of human beings that Machiavelli. According to Hobbes, if two individuals have desire of a certain thing, which they cannot enjoy at the same time, then they become enemies3. Hobbes argued that, people living in such state were continuously at war, and they could not differentiate between right and wrong. The two lived a life that was poor, solitary, short, brutish, and nasty. Resulting from his reductionist methodology, taking societal analysis to a position of human nature, he made his conclusion with a main realist assumption (anarchy). In such a state, every individual has his or her natural right for protection against injury or harm4. Therefore, Hobbes’s arguments purports that there must be fundamental laws to avoid the state of war. On contrary, Machiavelli does not reflect a theoretical state of nature like Hobbes. Howev er, Machiavelli argues, â€Å"there is no secret hand, which brings human activities into natural harmony†. Another factor differentiating these two political theorists is their diverging views about governance. According to Hobbes, it was the speculation on how a society functions without set rules. Hobbes felt that individuals would simply be doing things according to their own interests. Regarding how people should act, Hobbes makes

Truth About Food Labels Assignment Example | Topics and Well Written Essays - 1000 words

Truth About Food Labels - Assignment Example So lets study five categories of deceptive food tags one can encounter to the grocery store, to guarantee one does not play into the hands of vendors. Animal food products like meat and eggs, branded as "natural" must be minimally processed and comprise non-natural elements. Nevertheless, the natural label does not consist of any ideals concerning farm practices and simply applies to processing of meat and egg products. There are no principles or guidelines for the labeling of natural food products if they do not contain meat or eggs." That pretty much explains it all and expounds how Frito-Lay, owned by PepsiCo (PEP) , promotes "all-natural" Cheetos by lightly redefining the term as "No additives, no non-natural flavors, and no synthetic colors." Unless supervisory bodies step up administration, the industry will have to police itself. There is hope for improvement, however. Increasing pressure -- together with lawsuits -- mandated PepsiCo to alter its "Simply Natural" chip merchandises to "Simply" without altering ingredients. In August 2013, the U.S. Food and Drug Administration came up with a final rule defining the term for voluntary use. According to the rule, labels were to be brought to compliance defining food as either gluten free; or does not comprise an ingredient that is gluten-having grain, derived from a gluten-containing grain that has been processed to eliminate gluten, if the usage of that ingredient leads in the manifestation of 20 parts per million (ppm) or more gluten in the food. Also, any inevitable presence of gluten in the food must be less than 20 ppm." It is shocking to realize that Dominos Pizza offers gluten-free crusts that agree with the new canons. Unfortunately, one has to lob most other pizza offerings aside.
