Nitrogen Essays - Industrial Gases, Nitrogen, Pnictogen,

Nitrogen Nitrogen, symbol N, gaseous element that makes up the largest portion of the earth's atmosphere. The atomic number of nitrogen is 7. Nitrogen is in group 15 (or Va) of the periodic table. Nitrogen was discovered by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist, Antoine Laurent Lavoiser about 1776. Nitrogen is a colorless, odorless tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can be compressed into a colorless, crystalline solid. Nitrogen exists in two natural forms, and four radioactive forms (artificial). Nitrogen melts at -210.01 degrees C, (-349.02 F), boils at -195.79 C (320.42 F), and has a density of 1.251 g/liter at 0 C (32 F) and 1 atmosphere pressure. The atomic weight of nitrogen is 14.007. Nitrogen is obtained from the atmosphere by passing air over heated copper of iron. The oxygen is removed from the air, leaving nitrogen mixed with inert gases. Pure nitrogen is obtained by fractional distillation of liquid air; because liquid nitrogen has a lower boiling point than liquid oxygen, the nitrogen distills of first an can be collected. Nitrogen compresses about 4/5ths by volume of the atmosphere. Nitrogen is inert and serves as a diluent for oxygen in burning and respiration processes. It is an important element in plant nutrition; certain bacteria in the soil convert atmospheric nitrogen into a form, such as nitrate, that can be absorbed by plants, a process called nitrogen fixation. Nitrogen in the form of protein is an important constituent of animal tissue. The element occurs in the combined state in minerals, of which saltpeter (KNO ) and Chile saltpeter (NaNO ) are commercially important products. Nitrogen combines with other elements only at very high temperatures of pressures. It is converted to an active form by passing through an electronic discharge at low pressure. The nitrogen so produced is very active, combining with alkali metals to form azides; with the vapor of zinc, mercury cadmium, and arsenic to form nitrides; and with many hydrocarbons to form hydrocyanic acid and cyanides, also known as nitriles. Activated nitrogen returns to ordinary nitrogen in about one minute. In the combined state nitrogen takes part in many reactions; it forms so many compounds that a systematic scheme of compounds containing nitrogen in place of oxygen was created by the American chemist Edward Franklin. In compounds nitrogen exists in all the valence states between -3 and +5. Ammonia, hydrazine, and hydroxylamine represent compounds in which the valence of nitrogen is -3, -2, and -1, respectively. Oxides of nitrogen represent nitrogen in all the positive valence states. Most of the nitrogen used in the chemical industry is obtained by the fractional distillation of liquid air. It is then used to synthesize ammonia. From ammonia produced in this manner, a wide variety of important chemical products are prepared, including fertilizers, nitric acid, urea, hydrazine, and amines. In addition, an ammonia compound is used in the preparation of nitrous oxide (N 0) a colorless gas popularly known as laughing gas. Mixed with oxygen, nitrous oxide is used as an anesthetic for some types of surgery. Used as a coolant, liquid nitrogen has found widespread application in the field of cryogenics. With the recent advent of ceramic materials that become superconductive at the boiling point of nitrogen, the use of nitrogen as a coolant is increasing. In conclusion, it seems as if Nitrogen is very helpful in the modern world. It is used in dentists office's to using it for industrial applications. Without this element the world would be a little different in some fields.

Character Study - The Inspector from An An Inspector Calls essays

Character Study - The Inspector from An An Inspector Calls essays After watching an Inspector calls, I am sure it is obvious to any one who watches it that the inspector is not what he seems at all. At first you have no suspicions of the Inspector, but as the play gradually moves on it slowly dawns on you that the Inspector might be an impostor. In this essay I am going to write about a few different points, and who the Inspector might be. All of my theories may be correct but we will never know which theory is actually right. The Inspector is obviously as real as all the other characters in body and can eat and drink and is solid. I know that J.B.Priestley became very interested in the fourth dimension and time. That is why I think that the inspector may have gone back in time or there might have been a time slip of some sort to make sure that these people new what they had done. Another theory might be that the Inspector represents truth and is not a real person at all but just a representative of justice. I think that this is a very plausible idea and probably Priestley's own thought. I think that the Inspector gives it away when he gets far too emotional and worked up about things. A real police inspector would not get so involved. Here is an extract from the play, at the end of Act 2 where the Inspector gets too involved: Inspector: "(very sternly) Her position now is that she lies with a burnt-out inside on a slab. (As Birling tries to protest, turns on him.) Don't stammer and yammer at me again, man. I'm losing all patience with you people. What did he Say? Here the Inspector gets to emotional about such a small thing. I also think that a real police inspector would treat Birling with more respect. It is true what Birling says about him being a public man and telling the chief of police because he is a friend. Here is an extract were the Inspector treats Birling with disrespect; it is near the beginning of Act 2: Sheila: (urgently, cutting in) You mustn't try to build up a kind o...

Analyzing Plato's and David Hume's View of Death Essay

Analyzing Plato's and David Hume's View of Death - Essay Example The following will break down his argument concerning ‘prior knowledge’ or ‘recollection’. In turn, the philosophy of David Hume will be presented. Concerning death, Hume was famously a non-believer in any type of an afterlife, and famously, when his good friend Adam Smith visited him when he was dying, he just joked about it with him and was quite cheerful [Norton 23]. For Hume, all that exists, is within the 'perceptable' world. Where Plato maintained that we have prior knowledge, Hume argues that any notion of 'continuity' or 'sameness' through time, is a notion not that we are born with, but have been conditioned to have. What might appear to come from beyond the senses, is just the product of conditioning that begins in perception and the perceivable world. To state or argue that we have a priori knowledge, is to necessarily posit this as succinct from the senses. In other words, this is a form of knowledge which can be understood as ‘interactingà ¢â‚¬â„¢ with the senses or perception, but it is also a form of knowledge which is distinct as well. Toward establishing this important distinction, Plato raises the problem with respect to the notion of â€Å"equals† and unequal's. However, he arrives at these abstractions through an argument which claims that â€Å"learning is recollection† [Plato 73B]. ... However, this process of learning necessarily involves ‘recollection’, and second, we are capable of making abstractions concerning this process of learning. For example, from the notion of similarity and difference, we can arrive at more abstract notions such as ‘equal’ and ‘unequal’. Further, we can abstract these notions from the sensible or perceivable objects which there are often predicated of: â€Å"what of the equals themselves† [Plato 74C]. The â€Å"knowledge of the nature of the equal itself† [Plato 75B], is a problem which leads Plato to distinguish â€Å"prior knowledge† [Plato 74E] from â€Å"perception† [Plato 75B]. This is an important argument in relation to Plato’s notion of a â€Å"dualism between reality and appearance† [Russell 134], and moreover, it is an important problem with respect to the ontological difference between ‘continuity’ and ‘change’ which wa s raised in the introduction of the present analysis. In a sense, the â€Å"nature of the equal itself†, is given a different ontological status than things which are ‘unequal’. For example, in the world of ‘perception’, all things are different or unequal. In other words, there is change, decay, growth, death, corruption, generation, and so forth. As mentioned in the previous section, all of nature is marked by a process of â€Å"becoming† [Plato 71E]. Thus, if everything which we perceive is different and changing, and yet we are capable of abstracting notions such as ‘equality’ – that is, we have â€Å"knowledge of the nature of the equal itself†, then, where does this knowledge come from? We could not have acquired this knowledge through

Fukushima Nuclear Plant Disaster Research Paper

Fukushima Nuclear Plant Disaster - Research Paper Example If left unchecked, these can result in casualties equaling or even exceeding the body count of the previous natural disasters. This being the case, this study intends to take a look at the specifics of the incident – what occurred, as well as how and why. Concluding the study shall be a brief reflection on the incident and its immediate and distant aftermath. Table of Contents Abstract 2 Introduction 4 The Disaster 5 Radiation – The Deadly Consequences 8 Reflection 14 Conclusion 15 References 16 Introduction The disaster that occurred at the Fukushima I Nuclear Power Plant last March came right on the heels of the then-recent earthquake and tsunami that rocked the nation. The said occurrence was a consequence of these natural calamities, and was in fact joined by other nuclear accidents all over Japan. However, the one in Fukushima stands out as the largest. In fact, the magnitude of the disaster is said to be comparable to the tragedy at Chernobyl decades ago (Thomson- Reuters, 2011). The comparison to Chernobyl came courtesy of experts on the subject, which should say something on how catastrophic the Fukushima incident was. On the International Nuclear Event Scale, its rating was a 7, exactly the same as that of Chernobyl, whereas the Mile Island Disaster trailed behind at 5. As shall be explained below, the Japanese government tried to dismiss and downplay the incident to extent, but was eventually forced to concede to its magnitude. Fortunately, casualties resulting from the immediate disaster were relatively few. For sure, the natural calamities that preceded the disaster claimed over 9,000 more lives than the accident at Fukushima. Even then, the latter was still hardly equivalent to a slap on the wrist. The death toll immediately following the disaster numbered at 47. Two of these were Fukushima plant workers unlucky enough to get caught in it, and who sustained multiple external injuries before ultimately dying of blood loss. The other 45 who perished had been patients at an evacuated hospital in Futaba, and who had mostly been suffering from dehydration and starvation. Unfortunately, though, the relatively low immediate body count might be balanced out by an even bigger death toll if things are left the way they are now. As with the disaster at Chernobyl – and, more to the point, the bombings of Hiroshima and Nagasaki – the area remains irradiated, and cleanup efforts continue up till today. The threat of radiation is arguably the most terrifying thing to have come out of the disaster. The other consequences which have resulted from the accident cannot be seen by human eyes. However, these are unmistakably there, and can in fact result in a much higher body count if left unchecked. Even as it is now, the constant threat of being irradiated has rendered numerous surrounding villages and neighborhoods uninhabitable, which by itself is already a monumental setback for the unlucky ones living there (Maeda, 2011). The Disaster As already noted, the Fukushima disaster ranks among the biggest nuclear catastrophes in recent history, easily at par with or even exceeding what happened at Chernobyl (Thomson-Reuters, 2011) though still on a somewhat lower scale compared to the Nagasaki and Hiroshima bombs. Considering that multiple reactors were involved at Fukushima, in contrast with

Southwest Airlines' Cost Optimization to Create an Attractive Price Case Study

Southwest Airlines' Cost Optimization to Create an Attractive Price for Economy Class Travelers - Case Study Example There are many factors which have helped Southwest Airlines in its survival and success. This essay attempts to outline those factors and strategies on the basis of the following parameters: Financial Planning, Financial control, Costing, Decision making.Financial planning has played a vital role in growing its business. The correct timing of its decisions has made a huge difference in increasing market capitalization (Sims, 68). Southwest Airline has gained a further advantage by packing more seats into the aircraft which increase the seat kilometer revenue generated per block hour.Instead of buying more jets to deal with its growing business, Southwest planned and got better deals on the lease. Hence it paid substantially less per block hour for lease rental, than other carriers. Southwest has implemented its financial planning in such a way that low fares when combined with high frequencies and excellent punctuality have resulted in an increase in its revenues. Â  Southwest plans its finances very efficiently. Â  It hires new pilots with ten years contract and motivates them by offering a share in profits. This is an example of astute planning. It means that if Southwest was making losses at any particular time then the losses can be shared with the pilots. This strategy also makes the staff much more accountable. Another important aspect of financial planning was operating on low distance routes and targeting of road passengers.Southwest plans its expenditure very efficiently and effectively. The customer service strategy of providing a full meal was costly in two ways. One, it increases the per unit costs and secondly more staff is required to provide the service. Southwest’s plan of not following this trend has saved it the cost of food as well as the number of staff employed. In other airways, when six to eight employees per flight were required, southwest managed to function with only four. This kind of planning was crucial for decreasing the c osts and increasing the revenues.

Galileo Galilei And His Impact Theology Religion Essay

Galileo Galilei And His Impact Theology Religion Essay Galileo Galilei was a pioneer of modern science during a time period that revolved around religion, causing the great debate of religion versus science. His effect on his time period changed how people thought about the world and introduced science to everyone, rather than just the wealthy. His lasting accomplishments have made him one of the most influential scientists in world history. He made astounding discoveries in astronomy, mathematics, and physics; many of which are still used today. Galileo Galilei was born in Pisa, Italy in 1564. He was born to a noble family but had financial struggles which his father, an accomplished lutenist, tried to fix by giving music lessons (Fermi, 1996). Galileo had displayed an exemplary ability to learn at an early age, and his father decided that Galileo should attend the University of the Grand Duchy of Tuscany (Fermi, 1996). During his time at school, Galileo became interested in natural processes and science, and his life as one of the most renowned scientists ever had begun. During the 16th and 17th centuries when Galileo lived, the Scientific Revolution was slowly gaining more influence. The revolution began with Nicolas Copernicus with his heliocentric ideas and ended with Sir Isaac Newton and the discovery of multiple natural laws (Hatch, 2002). The reason this explosion of scientific discovery was known as a revolution was due to the radical ideas that scientists had put forth in relation to the ideas the Church had established in Western civilization. Before the Scientific Revolution began, the general understanding of the world was solely based on religion. The Revolution allowed people to replace their religious belief with facts and reason. This was not an easy transition, however, because religion and science have opposing ideals and during the Scientific Revolution these ideals clashed. The Roman Catholic Church, the largest and most influential Christian Church throughout history, had massive influence in Western civilization in the 16th and 17th centuries. The Church dominated most of the Western social life as their interpretation of the bible was the only accepted explanation to natural occurrences in the world (Hatch, 2002). Most scientific theories at the time were proposed by theologians, and all science that was taught was through the texts of these theologians and was universally accepted as true (Newall, 2005). Aristotle and Ptolemy were also referenced heavily in the Church. Church influence had begun to wane early in the 1500s, however, because of the Protestant Revolution and the rise of scientific theories proposed by scientists. These scientists, such as Nicolaus Copernicus and Galileo Galilei, had done experiments and discovered that their results didnt match up with the Churchs results. This led to a conflict between scientific and theological scien ce (Newall, 2005). The beginning of the differences between accepted scientific laws given by the Church and the actual scientists began with the Polish astronomer Nicolaus Copernicus and his De Revolutionibus, a book that explained that the earth revolved around the sun. Copernicus was timid about publishing the book because it went against almost 1400 years of the belief that the earth was the center of the universe, and the sun revolved around it (Fermi, 1996). Unfortunately for Copernicus, his book was very difficult to understand and did not gain any popularity. The small group of scientists that could understand Copernicus book would usually lecture about it, as it proposed more factual evidence as opposed to the theological teachings (Fermi, 1996). These scientists who agreed with Copernicus were known as Copernicans, and sought to spread his ideas. One of the most prominent Copernicans was Galileo Galilei. Before Galileo began his research on the Copernican Theory, he conducted experiments on laws of motion. Galileo was taught Aristotelian science, which was very inaccurate at the time. Galileo believed that Aristotles theory that objects fall according to their weight was false, so he publicly demonstrated an experiment where he dropped a large ball and a small ball from the Leaning Tower of Pisa, noting that they landed at about the same time (Drake, 1980). Galileo states the difference in his experiment and Aristotles in his book De Motu (meaning On Motion), stating Aristotle says that a hundred-pound ball falling from a height of a hundred cubits hits the ground before a one-pound ballà ¢Ã¢â€š ¬Ã‚ ¦ I say they arrive at the same time. You find, on making the test, that the larger ball beats the smaller one by two inchesà ¢Ã¢â€š ¬Ã‚ ¦ Speaking only of my tiny error, remain silent about his enormous mistake (Drake, 1980). Galileo called this the Law of Falling Bodies, stating that objects fall with the same acceleration (Drake, 1980). This was the precursor to Isaac Newtons first law of motion, which is still accepted today. Galileo made other great strides in physics and mathematics before he moved onto different subjects in science. Galileo has shown his mathematical skill when he created his military compass, or sector. This sector consisted of two rulers and an axis, and was used for many mathematical calculations (Fermi 1996). The sector was able to do many mathematical problems similar to our calculators today. During the sixteenth century, when there were many wars going on, it was especially helpful in military situations, such as figuring the formation of an army, the weight and arc of a cannonball, or the incline of certain environments (Fermi, 1996). This led to the sector being known as the military compass. In the early 1600s Galileo became interested in the invention of the early magnifying glass. He attempted to make his own version of the magnifying glass, and according to Stillman Drake (1996), he reasoned that one of the two lenses must be convex and the other concave, and on fitting such a spectacle lenses in a lead tube he found that it worked (pg. 46). His first magnifying glass was powerful enough to see ships approaching a couple of hours before they could be seen by the naked eye (Drake, 1980). After many hours of grinding and experimenting with different lenses, Galileo was able to create the first telescope. With his telescope, which was incredibly powerful for the time period, Galileo began his career as an astronomer. In May of 1609, Galileo used his telescope to look at the moon. He discovered that, contrary to everyones belief, the moon had mountains and craters all over it. Soon by January 1610, he had improved his telescope to be able to see Jupiter. Galileo noticed objects revolving around Jupiter and discovered them as moons (Shea, 2003). This was a huge step for Galileo in proving that the earth revolved around the sun and that the earth had a moon that revolved around it. After Galileo made his discovery, he published an article, saying: Here we have a powerful and elegant argument to remove the doubts of those who accept without difficulty that the planets revolve around the sun in the Copernican system, but are so disturbed to see the Moon alone revolve around the earth while accompanying it in its annual revolution about the Sunà ¢Ã¢â€š ¬Ã‚ ¦ our eyes show us four stars that wander around Jupiter, as does the Moon around the earth and these stars together with Jupiter describe a large circle around the Sun in a period of twelve years. (Shea, 1993) As Galileo observed the skies more frequently, he made more discoveries that proved Copernicanism was correct. While he made these discoveries, the Church had begun to persecute Galileo. Galileos work was censored by the Church while he published, so many of his studies werent completely published. The reason that Galileo was persecuted as opposed to other scientists before him was because of his ability to write in common Italian (as opposed to Latin) in a popular tone. This allowed everyone from scientists to bakers to read his works, and his works became immensely popular and were translated into several languages (Fermi, 1996). Because these works were so popular, it weakened the Churchs influence rapidly, forcing them to put Galileo under house arrest for the rest of his life. Galileo lived almost 400 years ago, but his contributions to science and astronomy have made a lasting impression on our world today. His creation of the telescope and his studies of the universe completely revolutionized how we view space, and without him it might have taken longer for mankind discover the earth revolves around the sun. Galileo was also able to make great strides in physics, such as discovering that everything that falls will fall at a uniform rate. Many people credit Newton with discovering this law of physics as it is stated as Newtons First Law of Motion, but Galileo was the one responsible for creating the first experiments to prove the law true. Galileo was also one of the first scientists to take a stand against theological thinking and promote scientific evidence, which is still a conflict that exists today. Considering Galileos accomplishments throughout his life, he is one of the most important and influential scientists in world history.

Graduation Speech: Tonight We Cross the Finish Line :: Graduation Speech, Commencement Address

Congratulations, County High Class of 2012, our thirteen-year marathon is over. Some of you may know I am a distance runner, part of an immensely successful cross-country and distance track program. We were fourth at the state cross-country championships, and we are the best senior boys team in the state. My involvement in athletics truly linked me with our school and granted me friends whom I will remember for a lifetime. One of the most important aspects of my time in high school was getting involved. Wherever your next journey takes you, don't sit back and watch the action. Take the initiative and you will experience the benefits. Just look around you. These are the people you grew up with, the people you were teammates with and the people you have survived dozens of classes with for the last four years. They are not merely faces in a yearbook. They are your people, your community, your family. They are the greatest benefit of being involved. Another concept I have learned from my participation in running is teamwork. No matter how hard we try, we cannot live our lives without others' help or without helping others. We must work together to succeed on the road ahead. This is the essence of teamwork. I know that even my personal success in cross-country and track is not solely mine. I know that my three district titles, one in cross country and two in track, in the 800 meter and 1600 meter runs, could not have been accomplished without my team's unequivocal support and for that, I thank them. However, along with the team element, we must remember one notion. Live life for you. Expect more out of yourself. Expect to reach the finish line, expect to finish first and expect to finish in one piece. Don't live your life striving to fulfill the expectations of your parents, your professors or your bosses. Live up to your own. Raise your expectations. Exceed them. Reach your potential. Now I have one thing to ask of you. Tonight, as we cross this finish line before us and set forth upon our next journey, strive to make a difference. Get involved to make our country a better place. Use teamwork to bring our people and the whole world together. I know to me personally, making a difference in our country and our world is paramount. Next week, I leave for the United States Military Academy at West Point, N.

Odi Case Study

Optical Distortion, Inc. HBS Case Study 9-575-072 Marketing Management MKT 6301. 002 – Fall 2012 Team Members Young soo Han Kevin Yang Jay Chi Lenny Liao Brad Standridge As of 1974 the chicken population in the US is already in excess of 400 million birds, with slow but steady growth expected through 1980. Given that fact that a great many of these birds live in tight quarters on very large chicken farms, a means of combating the chicken’s natural instinct to peck other chickens is needed. Pecking can actually lead to high mortality rates in flocks (cannibalization), which in turn raises the costs of farming.Debeaking has been used for some time with good results, but it has its own set of drawbacks. The lens developed by Optical Distortions, Inc. (ODI) holds the promise of reducing the threat caused by pecking, without some of the issues associated with debeaking. The specific advantages of these lenses will be discussed in the following report, as will a plan for mark eting this new product. By permanently inserting a pair of sight distorting lenses into the eyes of an egg-laying hen, studies have shown that cannibalization can be reduced from 9% to 4. %. Moreover, feed loss due to â€Å"billing† is substantially reduced relative to debeaked birds, allowing for much greater efficiency in feed consumption (less waste). Finally, given that lens insertion does not inflict the same trauma that debeaking does, egg production is not adversely affected. Given the above advantages, it is expected that farmers could increase their profit from egg sales by more than one-third (37%) simply by employing the use of the ODI lenses (Exhibit 1).Although the potential impact of the ODI lenses is substantial, there are some important assumptions underlying the anticipated value to farmers. For example, one of the biggest financial gains could be in the reduction in feed waste, so the assumption that hens with lenses will â€Å"bill† much less is crit ical. Test results have shown that flock mortality can be cut in half relative to debeaking, so another important assumption is that these positive results can be duplicated consistently in the field.Despite its disadvantages, debeaking is a practice which is familiar to chicken farmers, and the labor and cost associated with debeaking a flock is reasonably well known. It is assumed that a team of individuals trained to perform the lens insertion could process approximately as many chickens in an hour as they would if debeaking were done instead. This would keep the cost of insertion on par with debeaking and would thus lessen the concerns of the farmer. Tied to this is the assumption that a farmer’s own personnel could be readily trained in the art of lens insertion.Should this turn out not to be the case, it could prove nearly impossible for a large number of lenses to be deployed – a small team simply could not address the millions of chickens which would need to be targeted. If millions of lenses cannot be sold in the first year of business, ODI would find it difficult to survive against bigger competitors who are waiting to enter the market. This is thus an area of potentially high risk which needs to be addressed as early in the product introduction phase as possible.Bound up in the assumptions listed above is the underlying assumption that all chickens will respond in more or less the same way to the lenses. There are a number of factors which could allow ODI’s lens technology to quickly penetrate the market. One of the most important is the potential for farmers to experience a large profit increase (> 30% increase) through lower operating costs. Chicken farming is very price sensitive due to its low profit margin (roughly 6% profit on a dozen eggs from a debeaked bird).Use of lenses could allow this margin to increase to 8% or more (Exhibit 1); promoting this possibility should entice many farmers to give the lenses a try. Another key to quick market penetration is the achievement of one or two clear success stories. Given its very small size, ODI needs to focus its limited resources on product introduction at one or two large farms, continuing the focus there until the farmer/owner is pleased with the results. The farmer’s future endorsement of the lens approach would then be invaluable in generating interest from potential customers.As a means of attracting the participation of the first one or two trial farms, ODI could offer free lenses for up to 1000 birds, including insertion labor. It should be noted that penetration of the market can only occur if ODI can supply product in sufficient quantities. Given that there are millions of chickens to be serviced, it is imperative that ODI’s supplier be prepared to likewise supply millions of lenses on a consistent basis. The fact that ODI is bound by contract to a single lens supplier is itself a risk which must be analyzed.From a business continu ity perspective, it would be preferable if ODI could obtain its lenses from two different New World Plastics plants. This would then mitigate the risk somewhat should there be, for instance, a serious product quality issue at one of the facilities. As regards target segment, it would seem that the focus should be initially on farms with a flock size of 50,000 and over, since this would limit the overhead (fixed costs) needed to service these accounts (fewer sales and technical experts required).Also, by focusing on large farms, the sales team could interface with the farms directly, and there would be no need for a â€Å"middle man† to be involved in product distribution. Avoiding this intermediary would help keep costs down. Given the density of large farms in California (flock size of 50,000 or greater), it seems prudent not only to perform the initial product introduction there but to focus the entire first year of business in this single West Coast state. The first yearâ €™s planned production volume is approximately 20 million, essentially the same as California’s chicken population.Success in this region could later force farms in other states to implement the lens simply as a means of staying competitive. Rather than relying on word of mouth alone, ODI could promote its lens technology by participating in both industry trade shows and advertising in the leading poultry industry publications. Moreover, it is also possible that California’s Department of Agriculture could become an ally in promotion of lenses as a viable alternative to debeaking. It is proposed that lenses be sold at a price of $0. 09 per pair, which would in turn provide a profit per pair of $0. 026 (see Exhibit 2).Though the lenses appear to have a value to the farmer much greater than 9 cents, keeping the price in the â€Å"single digits† has a beneficial psychological effect and could help foster the perception that they are a good value. Moreover, if t he price grows much beyond this, the product will obviously be less attractive to farmers who might already be uneasy about adopting a new technology. Given a volume of 20 million units, a price of $0. 09/pair would produce an annual profit of $520,000. This sum would easily allow $250,000 to be directed toward future R&D (so the company can become more than a one-product company).Moreover, there would be more than a quarter of a million dollars remaining to fund rapid expansion the following year (to build a new regional office, for example). Exhibit 1 – Monetary Value of ODI Lenses to Farmers As regards putting a monetary value on the lenses, this can be estimated as follows: a. ($2. 50/hr*3 workers)/225 birds = $0. 033 (cost of inserting a pair of lenses in one chicken) This is essentially the same cost involved in debeaking a bird; for this reason it need not be taken into account when considering the benefits of lenses relative to debeaking. . Proposed cost of lenses to farmer: $0. 09 per pair c. ($2. 40*0. 045) = $0. 108 per chicken (savings in allocation for replacing dead chicken, relative to debeaked flock reduction in flock mortality from 9% to 4. 5%) d. ($158 / ton)(ton / 2000 lb)(156 lb per day / 20,000 chickens) (365 days) = $0. 225 per chicken (annual savings in feed assumes elimination of feed loss due to billing) e. Let’s see how b. and c. above translate into cost of production for a dozen eggs (assuming a chicken produces 22 dozen eggs per year): ($0. 108 + $0. 225 – $0. 09)/22 = $0. 11 per dozen eggs Thus, the cost to produce a dozen eggs would drop from $0. 50 (for a debeaked bird) to $0. 489, and a farmer’s profit per dozen eggs increases from $0. 03 for a debeaked flock to an estimated $0. 041 (assuming a selling price of $0. 53). This means a farmer’s profit could increase by approximately 37% if the lenses were used throughout the flock. Exhibit 2 – Pricing Considerations for a Pair of Lenses Fi xed Costs 1) Headquarters: $184,000 annually (for volume of 20 million pair) 2) Regional Office and Warehouse: $196,000 annually 3) Advertising in Trade Publications: $100,000 annually ) Participation in Industry Trade Shows: $100,000 annually 5) Costs of Molds: $12,000 x 3 = $36,000 (3 molds are needed to produce 21,600,000 pair annually) 6) Licensing Agreement with New World Plastics: $25,000 (per year, must be paid for 1st and 2nd year of production) Variable Costs $0. 032 per pair of lenses (cost to purchase from manufacturer, New World Plastics) So, in the first year of production, if 20,000,000 pairs of lenses are sold, the TOTAL COST would be: [($184,000 + $196,000 + $100,000 + $100,000 + $36,000 + $25,000)/20,000,000] + $0. 032 = $0. 064 per pair

Anthrax Virus essays

Anthrax Virus essays Anthrax is a horrible killer. Most that die are unknowing that they are even infected. The symptoms are black sores in the first instance, and abdominal cramp and vomiting and bleeding in the second. If the bacteria grows it will invade the blood stream and cause systemic disease. The inhaled spores are very fast acting. They travel very quickly to lymph nodes. Some of the cell stay in the lungs and cause fluids to build up. After its in the blood B. anthracis can expand because of their virulence factors. This affects the bodies immune defenses that are suppose to monitor the level of bacterial growth. The anthrax toxins also enter other cells and contribute to mortal illness. The toxins consist of three proteins: a protective antigen, edema factor, and lethal factor. These are harmless individually until they attach and enter cells. The way this happen is first the protective antigen binds to the cell where an enzyme trims off its outermost tip. Seven of those molecules form a ring that captures the two factors. Then the two factors attack the cells cytosol, and there they do their dirty work. They have now come up with ATR. It spans the cells membrane and protrudes from it. The protruding part has a receptor area, which are the attachment sites for particular proteins. The area is were the protective protein latches on or so scientist believe. Scientist would like to uncover the molecular interaction that enables protective antigen heptamers to move from the cell surface to inside the cell. I think that if they have come this far then its not long before they figure that out. The only anthrax vaccine approved for humans takes a different form. It consists of toxin molecules that have been treated to prevent them from making people ill. The way the do it is to grow a weaker strand and filter the bacteria cells from the culture and treating with formaldehyde to in ...

Essay Change Control

Essay Change Control Essay Change Control Faculty of Health Sciences, The University of Western Ontario, London, Canada Abstract Purpose – To explore the shared experience of organizational change from centralized allocation and control of services and resources to an empowering partnership approach to service delivery in one Canadian home care program. Design/methodology/approach – Applying an interpretive phenomenological design, data from in-depth interviews with a purposeful sample (n  ¼ 28) of providers, clients and informal caregivers were analysed using hermeneutic techniques, and validated by member checking and peer review. Findings – The overall experience of change was comprised of two dynamic change patterns: extrinsically introduced organizational development, facilitated by contextual factors; and intrinsically developed transformational change, impeded by the same contextual factors. The patterns together comprised participants’ enactment of an answer to the existential question, â€Å"To have or to be?† Research limitations/implications – While interpretive research does not elicit generalizable results, the ï ¬ ndings of this study illuminate the importance of choosing change strategies appropriate for the intended change, addressing what the change may mean to all involved, and confronting the contextual factors that undermine the change. Practical implications – New strategies are needed if engrained attitudes, values and beliefs about professional service delivery are to be changed. Originality/value – The interpretation exposes the nature of professional practice in health and social services, the impact of this work context on practice, and concrete strategies for managing organizational change. Keywords Organizational change, Health services, Home care, Social services, Canada Paper type Research paper Introduction Declining resources and organizational restructuring distract attention from efforts to develop more client-centred, empowering partnership approaches to health and social services delivery (Falk-Raphael, 1996; Montgomery, 1993; Stewart et al., 2003). Yet in the ï ¬ eld of home care, heightened consumer expectations and evaluations of approaches affording clients greater autonomy and voice in their care at home (Alberta Ministry of Health, 1993; Manitoba Ministry of Health, 1994; Saskatchewan Health, This interdisciplinary study was funded by the Medical Research Council of Canada and the Canadian Institutes of Health Research. The ï ¬ ndings and conclusions are those of the authors. No ofï ¬ cial endorsement by the funding bodies should be concluded, nor should it be inferred. The authors wish to acknowledge the technical assistance of Ms Lisa Tran with the preparation of Figure 1. Journal of Organizational Change Management Vol. 19 No. 2, 2006 pp. 119-135 q Emerald Group Publishing Limited 0953-4814 DOI 10.1108/09534810610648861 JOCM 19,2 120 1996) support change in this direction. The limited research evidence suggests that clients demonstrate potential for involvement (Fast and Chapin, 1996), but changing care approaches to empower them as partners in care may be slow (England and Evans, 1992), stressful (Charles et al., 1996) and impeded by organizational barriers (Ferronato, 1999; McWilliam et al., 1994, 2001). Publicly funded home care programs in Canada currently confront this dilemma. Their services normally are delivered in a brokerage model by a diversity of service providers with varying degrees of client involvement in their care. Providers include case managers, often nurses or social workers by professional background, who assess client needs, and based on their assessments, decide, access, coordinate, monitor and control amounts and timeframes of resources and services. These case managers act as brokers, contracting direct in-home service from other provider groups, including professional nurses, occupational, physical and speech therapists, and social workers, and

Identity Theft Essay Example | Topics and Well Written Essays - 750 words

Identity Theft - Essay Example It has become necessary for people to be adequately educated about the risks involved and the necessary preventive measures. Identity theft is a crime in which an imposter tries to pretend to be someone else by means of using some key identification data of the victim. This may include social security numbers, credit card numbers etc. When communicating online it becomes even easier to appear to be someone else since the communication is not face to face but online and the distance between the two persons or parties gives advantage to the criminal. The crime may be committed to seek monetary or social or any other form of benefit. Recovery from an identity theft may be easier in certain cases of small thefts involving individuals but it may become very grave if reputed organizations are victimized and they end up spending large sums in repairing the damage caused to their goodwill (World Privacy Forum, 2012). The crime is very diversified and innovated in the present day. The old-fas hioned methods of rummaging through the rubbish bins or picking pockets have been replaced by software, viruses and programming scripts. Computer viruses have proved to be efficient ways of committing identity theft in which all possible identity material of any person or organization may be extracted and put to use in another part of the world and the victim remains oblivious to such activities. Identity theft may range from simply posing to be someone else to more lethal actions such as financial identity theft, child identity theft, medical identity theft to seek medical care or drugs while pretending to be someone else or identity cloning in which the criminal assumes the complete identity of a victim in daily life (Compton, 2012). The identity thieves operating online usually work by tricking you into providing your personal information to them through various methods such as phishing, luring with job opportunities, money scams or fake fraud alerts. Phishing involves an email s ent to a victim which redirects him to a fake website where you are required to fill up a signup form with your personal information. Similarly job opportunity forms are sent and personal information is extracted. Fake fraud alert emails are sent which seem to be legitimate mail from the victim's bank. The victim is informed that someone has tried to fraudulently access his account so he must send certain personal information for verification (Federal Trade Commission, 2006) Today the society is very susceptible to falling for such tricks of criminals since the spoofed websites developed by criminals are so similar to the original ones that an average person cannot identify and differentiate between the real and fake. A simple change of address form may be filled up by someone and the utility bills of the victim will end up somewhere else resulting in nonpayment of a charge and a bad credit report. Furthermore, the personal data commonly available on social networking websites may b e used by criminals to communicate with a victim's contacts and seek financial benefits while pretending to be him. An ATM or a credit/debit card may be duplicated and money drawn from a victim's account. Thus it is clear that every individual and organization must educate itself and others about the seriousness of the implications this crime can have. To address the crimes of identity theft, all countries and states

The World of Word Processing Essay Example | Topics and Well Written Essays - 1000 words

The World of Word Processing - Essay Example The word processor for several years featured a monochrome display and the ability to save documents on diskettes or otherwise. The later models had innovations like grammar checking, formatting options, and the dot matrix printing (Ward, 2005). This Microsoft word is the most widely used processing software with over one billion users across the globe. Other commonly used word processing applications are the word perfect that dominated in the years of the mid 1980s and early 1990s, the Microsoft MS-DOS, and the open source application. The current word processor is very power and consists of images, graphics, and the text latter handled with typesetting capability. The term word processing, invented in the late 1960s by IBM, got recognition by the by the New York Times as a buzzword in 1971. The international Business Machines provided a program that would generate printed documents on a mainframe computer and described it as a word processor. The new software combined peoples, proc edures, and applications that would transform idea into printed communications. The original Microsoft word contained a dictating machine and a manually operated S electric typewriter. The term word processor was taken to mean a semi automated typewriters with some form of electronic editing and correction ability (Gordon, 2010). Most of the persons working in the United States as secretaries utilized the word processing and it had impact on their careers. By this time, the word processing replaced the traditional secretary and emphasized more on the administrative roles of the businesses and industry. The invention of the word processor occurred in two phases. There was first the standard operating system control program that vastly brought increased standardization in the 1970s. The format for all the files and memory had similar structure across all the machines of that class. To change the type meant stopping the printer and a manual change of printing element (Castro, 2003). Th e additional memory made bi-directional printing possible hence eliminated delay caused by the return of print head to the left of the margin possible at the start of every program. The second phase was the introduction of the Microsoft disk operating system to replace the control program Microsoft (Word processor is a facility that records keystrokes from the keyboard and prints the same onto a paper in a separate operation system. It is used in the production of any sort of printable material (Ward, 2005). The word processor encompasses a stand-alone machine that combined the keyboard text-entry and printing function with a dedicated processor for the editing of texts. The features and the designs varied between the manufacturers but new features added advanced the technology.
