The Necklace Essays - The Necklace, Necklace, Elizabeth IIs Jewels
The Necklace The Necklace The theme of Guy de Maupassant story The Necklace seems to be suggested by the line, What would have happened if Mathilde had not lost the necklace?. Mathilde Loisel grew up in poverty and had no expectations in life. When she got married, her and her husband would sit around the dinner table and imagine they were eating a luxurious meal. They would imagine using shiny silverware and eating their meal on marvelous plates. Together, they had nothing. Mathilde had no clothes, no jewels, and only one friend. One day her husband came home from work and handed her an invitation they had received to attend a ball. Her husband thought that she would be enthusiastic about it, however she busted out in tears. She wanted to attend, yet she had no dress to wear. After digging in to money they had been trying to saved, Mathilde purchased a dress for the ball. As the ball drew near, Mathilde decided she still needed something more to finish off the dress they had just spent so much money on. The next day, Mathilde visited her only friend to see if she could barrow some of her jewelry for the evening of the ball. After about an hour of deliberating with her friend about what to jewelry to wear, Mathilde found it. Under all the other pieces of jewelry lied a diamond necklace. Mathilde was ecstatic. Never before had she seen such a beautiful piece of jewelry. She decided this was what she was going to wear. The entire way home she dazzled the necklace. She knew that she would stand out in the crowd at the ball. The night of the ball came and Mithilde looked great. Her and her husband showed up at the ball and everyone was amazed at how good Mithilde appeared. Mithilde was not used to all the attention she received that evening, after all she just a poor young lady. The evening ended and everyone went home. Mithilde decided that one last time she would look at herself in the mirror before getting out of the clothes. When she did, she noticed the necklace in which she admired so much was gone. Weeks went by and no trace of the necklace showed up. Mithilde and her husband had to borrow thirty-six thousand francs from people they knew to buy another just like it. Mithilde put the new necklace in a box and gave it to her friend. Her friend never looked in the box, so she did not know the necklace was not the same she let Mithilde borrow. Mithilde and her husband were deeply in debt. For ten years they worked day in and day out until finally the debt was paid off. Mithilde looked as if she was a very old lady, however she was not. One day Mithilde was walking in a park and stumbled across a lady walking with a child. When she took a second glance at the lady, she noticed it was her friend, in which so long ago let her borrow the diamond necklace. When she approached the long time friend, the lady did not even recognize who it was. After moments of conversing, Mithilde decided to tell her friend of the incident that happened so long ago concerning the necklace. Her friend was appalled to hear of it and told Mithilde that the necklace that she let her borrow was only paste. It was only worth at most five hundred francs. No one really knows what would have happened if Mithilde would have been honest with her friend to begin with and told her about the problem. All the ten years that Mithilde and her husband spent working to pay back for the necklace, they could have been using that money to better themselves. The point the author was trying to get to the reader was that you should be honest. If you are not, then you may have a harder problem on your hands in the end. In Mithildes case, she did not want to tell her friend of losing the necklace in fear that her friend would betray her. Her consequence for not telling her friend was working everyday for ten years. Honesty in the present

Crime misc0 essays
Crime misc0 essays From the beginning of time, crime has been evident in human existence, and from the first crime there has always been a punishment. And it came to pass, when they were in a field, that Cain rose up against his brother, Able, and slew him (Genesis 4:8). This for many people was seen as the first crime. This crime did not go unpunished. Cain was then ostracized from his colony and sent to wonder as a vagabond and a fugitive for his crime (Genesis 4:14). He was also branded with the mark of a murderer. Therefore, the presence of crime in human life is inevitable. Defined in Websters Dictionary, crime is, an act of violation against society and its laws. Punishment is the consequence of the crime. Crimes like fraud, burglary, assault, etc., are usually punished by prison terms. Murder, manslaughter, and homicide maybe punished by prison terms or death. Electrocution-the three legged oak chair was constructed in 1923 by inmates and is still used today. (ironic isnt it?) The electrocution cycle is two minutes or shorter in duration. Voltage and amperage levels peak on three occasions. Maximum current is 2000 volts and 14 amps. The executioner is an anonymous, private citizen who is paid $150 per execution. The position of executioner was advertised in several Florida newspapers in 1978. Lethal Injection-execution by lethal injection involves the continuous intravenous injection of a lethal quantity of a short-acting barbiturate in combination with a chemical paralytic agent. A number of doctors have pointed out that drugs may not work effectively on diabetics or former drug users, whose veins may be hard to reach. In some cases minor surgery may be required to cut in to a deeper vein, according to medical testimony. More states use this form of execution than all US states. Gas Chamber-prisoner is restrained in a hermetically sealed steel chamber below which is a pan. Upon a signal, the...

If you dont pee in your pants or throw up, youre not running fast enough.
If you dont pee in your pants or throw up, youre not running fast enough. On a call with my transformational growth group last week, one of the participants shared her high school running coachs words to the team: If you dont pee in your pants or throw up, youre not running fast enough. I immediately recalled a recent yoga class that I attended, where at the peak of the practice in a hot room I attempted- and came close to achieving- a difficult arm balance pose. I felt a wave of nausea come over me and knew I was venturing into new territory. Then I thought about last summer at the outdoor pool, when I watched a kid on the swim team barf by the fence and then hop right back into the pool. Other images, like early contestants on The Biggest Loser losing their cookies repeatedly, also came to mind. Similar physical reactions can result from experiencing strong emotional reactions. I have seen people vomit while doing emotional work; and I certainly know the feeling of queasiness that can come from touching deep emotional fear and pain, or from taking a risk in interpersonal communication. Sometimes simply the thought of doing something new or different for my business makes me want to throw up. What all these triggers have in common is that they arise when people are pushing past their comfort zone- which, by definition, is not comfortable! But this doesnââ¬â¢t mean that the activity or work is something to be avoided. If thereââ¬â¢s anything new you want in your life, whether a physical result or an emotional transformation, you will experience discomfort on the way to achieving it. Is there somewhere in your life where you are jogging along, letting yourself get comfortable and staying there?à What would it look like to push past your comfort zone?à Are you willing to experience fear, nausea, or even peeing in your pants to get the result you want? Im choosing to take that feeling of nausea and/or fear as an indication that Im pushing my life in ways I want to push it. It means Im digging deeper. The payoff is stronger muscles, stronger relationships, and a stronger business. If you want to stretch more than youââ¬â¢re stretching in your life and work, and feel like you donââ¬â¢t have the tools or courage to do it, I recommend the training Iââ¬â¢ve been taking part in for the past 2 years. See www.transformweekendtraining.com. The next weekend introductory workshop is March 13-15 in Chicago and you can register for free using code TTCOMP. I will be there and would love to meet you!

What you think about tattoos and piercings Essay
What you think about tattoos and piercings - Essay Example There are different reasons why I consider tattoos and piercings as undesirable. First, these are costly. In order to get yourself tattoos and piercings from qualified professionals, it will cost a considerable amount of money. If there are other more important things to do with oneââ¬â¢s money, an individual would reconsider spending money on getting a tattoo or body piercing. Tattoos are also undesirable since they are permanent. When one gets the first tattoo or body piercing, they will be motivated to get some more. This has resulted to some people having their bodies covered by tattoos. Since these are permanent, removing them is quite challenging. If one wants them to be removed, he or she will equally spend more money paying specialists to remove the tattoos. Furthermore, tattoos and piercings are painful. This is mainly during the process of tattooing and piercing. No one wants to feel pain. Therefore, I do not consider the pain of getting a tattoo or piercing to be worthwhile. Equally, the process of removing a tattoo is also more painful. Finally, tattoos and piercings might expose an individual to the risk of diseases, such as HIV/AIDS. However, this depends on who performed the tattooing and where it was performed. This is because; needles or sharp instruments are used on an individual during piercing and tattooing. Therefore, failure to clean and sterilize needles, might lead to the infection with diseases such as HIV/AIDS. Nonetheless, each person has their likes and dislikes; and this is to some extent influenced by their culture. Therefore, even though I dislike tattoos and piercings, I understand and appreciate those people that adore them, hence this is not a major issue to

The Issue of Population Growth Essay Example | Topics and Well Written Essays - 750 words
The Issue of Population Growth - Essay Example There is only so much room left on the planet where humans can expand as well as use to grow food. The aspect of supply and demand is always in motion as producers try to keep up with the increasing demands associated with large populations. In particular, corn is one of the most commonly used and exported crops that are used around the world. Not only is corn used as a food supply for both humans and for livestock, but also it is also valued for its use in ethanol. This adds to an increase in the supply and demand, which is becoming detrimental to society as society uses resources more quickly than they can be replaced by both nature and society (Lehmijoki and Palokangas). As a result of becoming a more developed society, there are also consequences happening in the physical world. One of the first aspects in which the world started feeling the consequences of human expansion began with the breakdown of the ozone layer due to the use of CFCs, chlorofluorocarbons. Since then, many more toxic fumes have been dumped into the atmosphere messing with the equilibrium that has been maintained in our atmosphere. In addition, the world needs the energy to run. Society has been consumed with obtaining natural resources that are not quickly renewable such as oil and gas. This has resulted in accidents such as the Exxon Valdez and the Deep Horizons incident that occurred in the Gulf of Mexico (Hall and John). Strip mining, especially in Africa, leaves the landscape scarred by mining for coal and other precious metals. Lakes and rivers are being harnessed for hydroelectric power, however, these freshwater resources are drying up due to overuse, which then affects c rops and living areas leading to desertification.

Shaft Essay Example for Free
Shaft Essay The Lathe Turning is one of the most common of metal cutting operations. In turning, a workpiece is rotated about its axis as single-point cutting tools are fed into it, shearing away unwanted material and creating the desired part. Turning can occur on both external and internal surfaces to produce an axially-symmetrical contoured part. Parts ranging from pocket watch components to large diameter marine propeller shafts can be turned on a lathe. The capacity of a lathe is expressed in two imensions. The maximum part diameter, or swing, and the maximum part length, or distance between centers. The primary task of a lathe is to generate cylindrical workpieces. The process of machining a workpiece to the required shape and size by moving the cutting tool either parallel or perpendicular to the axis of rotation of the workpiece is known as turning. In this process, excess unwanted metal is removed. The machine tool useful in performing plain turning, taper turning, thread cutting, chamfering and knurling by adopting the above method is known as lathe. Schematic illustration of the components of a lathe Schematic illustration of a turning operation showing depth of cut, d, and feed, f. utting speed is the surface speed of the workpiece at the tool tip. (b) Forces acting on a cutting tool in turning. Fc is the cutting force; Ft is the thrust or feed force (in the direction ot teed); and Fr is the radial torce that tends to push the tool away trom the workpiece being machined. Manufacturing processes used during the making of the power shaft: Turning Turning in a lathe is to rem ove excess material from the workpiece to produce a ylindrical surface of required shape and size. Straight turning The work is turned straight when it is made to rotate about the lathe axis and the tool is fed parallel to the lathe axis. The straight turning produces a cylindrical surface by removing excess metal from the workpieces. Step turning Step turning is the process of turning different surfaces having different diameters. The work is held between centres and the tool is moved parallel to the axis of the lathe. It is also called shoulder turning. Facing Facing is the operation of machining the ends of a piece of work to produce flat urface square with the axis. The operation involves feeding the tool perpendicular to the axis of rotation of the work. Chamfering Chamfering is the operation of bevelling the extreme end of the workpiece. The form tool used for taper turning may be used for this purpose. Chamfering is an essential operation after thread cutting so that the nut may pass freely on the threaded workpiece. Grooving Grooving is the process of cutting a narrow goove on the cylindrical surface of the workpiece. It is often done at end of a thread or adjacent to a shoulder to leave a mall margin. The groove may be square, radial or bevelled in shape. Thread cutting Thread cutting is one of the most important operations performed in a lathe. The process of thread cutting is to produce a helical groove on a cylindrical surface by feeding the tool longitudinally. But we did it manually using a die. Filling Filing is a final material removal process in manufacturing.

Duels :: Essays Papers
Duels "This is the excellence of Court: take away the ladies, duels and the ballets and I would not want to live there." - A. d'Aubigne, Baron de Foeneste, Il, 17 Duels and the act of dueling is something that has characterized not only the imagination of historians and modern warfare enthusiasts, but also the minds of writers and readers of literature for years. The numerous literary variations on the theme of dueling are enough of an indication of its importance, and the fascination with the act continues to increase. However, dueling is more than a literary climax or a plot twist; duels have been being fought for centuries and are actually derivatives of many medieval practices. The word duel has several predecessors, depending on which history is being referenced. The most common form of the word is derived from the German word Duell, which is a derivative of the Latin word duellum. Duellum is a combination of the Latin words bellum and duo, which connotes a war between two. This simple definition seems to be the most common and the most recognizable. Historian Francois Billacois states that a duel is "a fight between two or several individuals (but always with equal numbers on either side), equally armed, for the purpose of proving either the truth of a disputed question or the valour, courage and honour of each combatant (Billacois, 5)." Historian Ute Frevert concurs, but points out that duels, especially in the modern era, were "no mock fights, but serious passages at arms in which the opponents risked their lives and which could result in serious injury, or even death (Frevert, 11)." Most contemporary historians believe that the modern version of the duel developed out of three medieval institutions: the feud, the judicial duel and the knightly tournament. The belief that dueling was derived from these three events is often referred to as the continuity theory. Feuds in the medieval period occurred when people attempted to settle disputes and exact revenge for insults through "private vengeance," rather than by going to the authorities and entrudting them to settle the matter. Judicial duels, on the other hand, were official acts, during which both parties (the plaintiff and the defendant) fought their grievances out on the battle field with swords in front of a judge.

Culture is learned
Which country has the richest culture? You can't quantify richness of culture. No one is better than the others, in my opinion, every culture has their own uniqueness. Culture is learned I would say any culture or sub-culture is learned. It's environmental. Every culture is learned by the people who live It. Even people born Into a culture learn the culture as they grow and mature. I think almost everything is cultured and everyone is cultured.For instance, we were born as babies, we had not learned anything yet, but we were able to cry, and express our feelings In certain ways. There was no culture Involve until we learned and observed from our parents or others how to do things to follow our custom rules, and so forth. How culture Is developed? By formulating rules, norms and beliefs. Culture Shock Culture Shock Is a term used to describe the anxiety produced when a person moves to a completely new environment. Usually, the way that we lived before is not accepted or considered nor mal in the new country.Everything is different, for example, not speaking the language, not knowing how to use simple everyday Items such as banking machines or knowing how to take a bus. Week 6 reflection How many people must to perform his/her duty In the society In order for you to sit In the classroom right now? That's too many people that I couldn't even count it out. I think every citizen is related and It's all somehow connected. It's a human society CHAIN. Parents pay tuition fee for me to study In university.But their salary comes from the revenue of their business. The revenue comes from the purchase of the consumers, etc. School gets paid in order to run the system well, and it also needs professor and administrators to take care of. So I thank every person in this society. I do believe people present themselves in different ways in different situations with different people. It's all about impression management. That's what you really should Humans have developed the abi lity to quickly decide whether a new person will hurt or enrich us.Just three seconds are sufficient to make a conclusion about fresh acquaintances, so I think impression management is really important to everyone. Social exchange models assume that rewards and costs drive relationship decisions. Both parties in a social exchange take responsibility for one another and depend on each other. Worth = Rewards ââ¬â Costs If worth is a positive number, it is a positive relationship. On the contrary, a negative number indicates a negative relationship. The worth of a relationship influences its outcome, or whether people will continue with a relationship or terminate it.

When more income is earned the demand for goods will shift to the right as more goods and higher levels of goods are demanded across the board. The budget line follows the law of demand as it shifts to the right showing an Increase In the quantity demanded of Items. This should not be confused with movement along the curve which Is caused by a change in price of a specific good. The purpose of a market system To allow government to control what is sold. To set constraints between buyers and sellers. To bring buyers and sellers Into contact * d.To allow an organization to set prices In relation to their products. Rejoinder: In the market system an exchange of money for goods and or services takes place. A true market system sets the price through barter where the goods and services sell for the best price offered by the buyers creating equilibrium. For this exchange to take place the market serves as a meeting place for buyers and sellers. If the organization sets its prices there may not be market equilibrium and that can result in either a shortage or a surplus.By specializing In the production of one good a company Is able to benefit from economies of scale which Increases their revenues. Attributes of specialization Include Reducing costs by creating a surplus. Saving time by allowing a worker to focus on one task* Encouraging workers to learn new skills. Encouraging workers to learn a number of different skills. Rejoinder: Specialization occurs when a firm is able to use the resources available to it to produce one product or family of products rather than trying to produce multiple goods and spreading the firm's resources In many directions.By focusing or concentrating on one task workers can achieve a higher level of training in that skill and become more productive. Firms always strive to produce only the amount of reduce they can sell to maximize their profits. The market system promotes progress by a, Creating incentive to continue to do things In the same way b. Restricting the amount of capital directed to specific goods. C. Slowly adjusting to changes In the In ten prices AT resources. A Provoking Incentive Tort technological advances.Rejoinder: Because firms are competing for consumers' dollars they always want to have the newest and latest product available which will be the most advanced in their category and appeal to consumers as new purchases. This provides incentive to stay ahead of the competition in developing new technology. If a firm continues without advancing its product the competition that do advance will attract their customers which is why firms dedicate resources to research and development.Revenue increases when producer surplus increase* producer surplus decreases consumer surplus increases consumer surplus decreases. Rejoinder: Producer surplus is the difference between the minimum price the producer is willing to receive and what they actually receive. The surplus is their profit and the larger the surplu s the greater their profit on the good. When it decreases they are receiving a price closer to their minimum acceptable. The consumer surplus measures what the consumer is willing to pay and its difference from the market price.The closer to the market price the higher the consumer surplus because they are spending less than they are willing to and the less spent the lower the revenue will be for the good. An increase in the price of an inelastic good will decrease revenues decrease the percentage change in quantity less than the percentage change in price increase revenues* increase the percentage change in quantity more than the percentage change in price Rejoinder: Inelastic goods are necessities that consumers will continue to arches even when price increases.This increases the revenue as more is paid for each good. The percentage change In price increases faster than the change in quantity which may remain constant. When we pay more for a good or service revenue will increase. Objective 1. 2: Explain market equilibrating process Productive efficiency is when the most valued combination of resources is used. The best technology is used. * when production occurs at a fair cost per unit. Fewer resources are left for production of other goods.Rejoinder: Efficiency is when we get the most out of the resources that are used to produce a good. This means having the newest and unsurpassed technology to produce the least waste and the lowest cost. Unused resources due to the new technology can then be allocated to the production of other goods. The market is said to be in equilibrium when there is potential for a shortage but not a surplus there is potential for a surplus but not a shortage. Neither a shortage nor a surplus exists* the quantity sold equals the quantity purchased. Appliers are asking for a product. It is the market price where the two come together and all the goods produced are sold without leaving anyone demanding additional units of that good. T he market will move too higher equilibrium price if the decrease in supply is greater than the decrease in demand* the increase in supply is greater than the increase in demand. The decrease in demand is greater than the decrease in supply. The increase in demand is greater than the increase in supply. Rejoinder: Price serves as a rationing tool for the demand of goods.If the price is too high fewer of the good are demanded and if it is too low more of the good is demanded than is available. The market seeks a price where the demand for goods will equal the supply of goods. When supply decreases the price will ration the good y increasing till there is no excess demand for the good or shortage of the good. The intersection of supply and demand will be at a lower equilibrium price but a higher equilibrium quantity if supply is constant and demand increases. F supply is constant and demand decreases if demand is constant and supply decreases. If demand is constant and supply increases * Rejoinder: Supply and demand intersect at the equilibrium price. The demand curve is a straight line measuring the quantity demanded at different price levels. When supply increases the supply curve shifts to the right and more of the good is available. Since the demand curve remains constant the supply curve will intersect at a lower point indicating the increase in quantity.When a price ceiling occurs the market price will be lower than the equilibrium price * the market price will be higher than the equilibrium price. The supply will exceed the demand buyers will not be willing to pay more than the ceiling price. Rejoinder: A price ceiling is the maximum price that can be charged for a good or service. It is imposed below the equilibrium price to allow those who would otherwise not be able to afford the good to purchase it. Placing it above the equilibrium price would make it ineffective ND unnecessary as the market price would then prevail.Income elasticity increases when the number of complementary goods decreases when the number of substitute goods decreases when buyers' income decreases* when buyers' income increases Rejoinder: Income elasticity measures the percentage change of the quantity demand to the percentage change in a consumer's income. If the consumer's income changes disproportionably to prices it affects the demand for goods. If income decreases and the price of goods stay the same then fewer goods are affordable and more goods become elastic as they are no longer a necessity or must have to the buyer.

buy custom Chemically Modified Foods essay
buy custom Chemically Modified Foods essay Genetic engineering is a science that involves the modification of plants and animals genetic material. This was historically practiced by farmers, but recently, it was approved as a food production technology. The manipulation of DNA and transferring it to a different organism introduces a trait of any organism to animals, virus, bacteria or plants, and the transgenic organism are programmed to produce in bulk substances such as hormones, nutrients, monoclonal antibodies, enzymes, and various pharmaceutical products such as vaccines and drugs (Uzogara, 2000). This technique is used to transform animals and plants for use as food, and this has created a controversy of whether the food is good for human consumption or not. This paper will discuss the possible effects of chemically modified foods on human health and environment. Chemically modified foods were developed to save the human race and animals from the problem of food crisis, however, according to critics of this technology; the foods produced have raised concerns, not only for the altered nutritional quality, carcinogenicity, toxicity, allergenicity and safety, but also for the effects it has on the environment (Amin Jahi, 2004). The critics highlight that the transfer techniques of genes can lead to mistakes that are beyond correction by human efforts (Uzogara, 2000). The genetic materials might not be transfer to the target cells, any transfer to the wrong cell might lead to unexpected mutation, causing infertility, toxicity or unsuitability. The potential risks associated with such an occurrence are; Alteration in the Quality of Foods When genes are transferred to the wrong cells, they might cause a change in the nutritional value of foods; the levels of certain nutrients might increase as the level of other decrease. However, there is little research on the effects of the change in the levels of food nutrients. Critics highlight that the technology of chemically modified foods changes at a greater pace that scientists are not able to predict the effects and the extent of the effects on pediatric nutrition; for this reason, they advise people to avoid feeding infants with chemically modified food products. Allergenicity from Chemically Modified Foods Critics also concerned with the effects that might be caused by the chemically modified food plants; these foods might transfer allergenic characteristics of the gene donor plant or animals to the recipient plant or animal. Moreover, the chemically modified foods use donor micro-organisms whose potential to cause allergenicity is untested or not known (Uzogara, 2000). There is a potential for new gene combination and non-food sources to cause allergic reactions or aggravate the existing ones. Toxicity The modified foods are also accused of enhancing natural plant toxins; according to the Uzogara, as the desired gene is switched on in plants, the gene might also increase the capacity of the plant to release poison. According to Uzogara (2000, p. 185), Genes for some natural toxins such as protease inhibitors in legumes, cyanogens in cassava and lima beans, goitrogens in canola species, and pressor amines in bananas and plantains, may be turned on and lead to an increase in levels of these toxins which can pose a hazard to the consumers of these crops. Resistance to Antibiotics Maker genes with antibiotic resistance are mostly used in genetic engineering; there are concerns that when antibiotic resistance genes are used in breeding food crops, they might have harsh consequences to the consumers of the breed food crops. A report from the British Medical Association highlights that when maker genes with antibiotic resistance are inserted in some crops, they transfer microbes that cause diseases in animals and people consuming the foods. This might cause antibiotic resistant microbes in the animal or human population, thereby causing antibiotic resistance among the population (Wieczorek, 2003). Environmental Concerns The human and plant populations are affected by any destruction done to the environment, and this is why the environmentalists are concerned about the effects of the genetically modified food crops. According to Amin Jahi (2004, p. 103), the environment is valued for what it can provide for humans, and we protecct it so that the resources will be there for our use and that of future generations. Genetic engineering recommends the cultivation of crops that are resistant to insects and contains herbicides, however, according to environmentalists, these crops could pollinate wild species, creating super-weeds among wild plants; this might have consequences that are yet to be known (Wieczorek, 2003). These super-weeds can affect plant yields, whose consequences include a disruption of the natural ecosystems. The weeds might be difficult to control, thus requiring expensive control programs. Also, the genetic engineers work hard to enhance plant resistance, and if they do not take precau tions, they could introduce new viruses, which might pose risks to other organisms in the environment. Benefits of Genetically Modified Foods The genetic engineers have defended these claims by saying that, foods that are manufactured through genetic engineering are subjected to rigorous testing before are made available for human consumption. Besides, these foods also have health and environmental benefits. For instance, chemically modified fruits such as tomatoes have an improved shelf-life as well as quality. AccordingWieczorek (2003, p. 2), Farmers use crop-protection technologies because they provide cost-effective solutions to pest problems which, if left uncontrolled, would severely lower yields. The production of chemically modified foods enhances milk and meat production among other foods, which helps to alleviate nutritional problems around the globe. Genetically modified foods also have environmental benefits; they come up with biological defense against stresses, viruses, herbicides, pests, weeds and diseases. Also, the genetically modified plants have been found to remove industrial waste and recycle toxic wastes. Conclusion Analyzing the debate on genetically modified foods and its effects on human and animal health, as well as the environment, more research has to be done on this issue in order to clear the doubts of consumers, and for genetic engineers to be sure of the effects and implications of genetically modified foods before releasing it for human consumption.

Fundamental Physical Constants in Physics
Fundamental Physical Constants in Physics Physics is described in the language of mathematics, and the equations of this language make use of a wide array of physical constants. In a very real sense, the values of these physical constants define our reality. A universe in which they were different would be radically altered from the one that we actually inhabit. The constants are generally arrived at by observation, either directly (as when one measures the charge of an electron or the speed of light) or by describing a relationship that is measurable and then deriving the value of the constant (as in the case of the gravitational constant). This listing is of significant physical constants, along with some commentary on when they are used, is not at all exhaustive, but should be helpful in trying to understand how to think about these physical concepts. It should also be noted that these constants are all sometimes written in different units, so if you find another value that isnt exactly the same as this one, it may be that it has been converted into another set of units. Speed of Light Even before Albert Einstein came along, physicist James Clerk Maxwell had described the speed of light in free space in his famous Maxwells equations describing electromagnetic fields. As Albert Einstein developed his theory of relativity, the speed of light took on relevance as a constant underlying important elements of the physical structure of reality. c 2.99792458 x 108à meters per secondà Charge of Electron Our modern world runs on electricity, and the electrical charge of an electron is the most fundamental unit when talking about the behavior of electricity or electromagnetism. e 1.602177 x 10-19 C Gravitational Constant The gravitational constant was developed as part of the law of gravity developed by Sir Isaac Newton. The measurement of the gravitational constant is a common experiment conducted by introductory physics students, by measuring the gravitational attraction between two objects. G 6.67259 x 10-11 N m2/kg2 Plancks Constant The physicist Max Planck began the entire field of quantum physics by explaining the solution to the ultraviolet catastrophe in exploring blackbody radiation problem. In doing so, he defined a constant that became known as Plancks constant, which continued to show up across various applications throughout the quantum physics revolution. h 6.6260755 x 10-34 J s Avogadros Number This constant is used much more actively in chemistry than in physics, but it relates the number of molecules that are contained in one mole of a substance. NA 6.022 x 1023 molecules/mol Gas Constant This is a constant that shows up in a lot of equations related to the behavior of gases, such as the Ideal Gas Law as part of theà kinetic theory of gases. R 8.314510 J/mol K Boltzmanns Constant Named after Ludwig Boltzmann, this is used to relate the energy of a particle to the temperature of a gas. It is the ratio of the gas constant R to Avogadros number NA: kà R / NA 1.38066 x 10-23à J/K Particle Masses The universe is made up of particles, and the masses of those particles also show up in a lot of different places throughout the study of physics. Though there are a lot more fundamental particles than just these three, theyre the most relevant physical constants that youll come across: Electron mass me 9.10939 x 10-31 kgà Neutron mass mn 1.67262 x 10-27 kgà Proton mass à mp 1.67492 x 10-27 kgà Permittivity of Free Space This is a physical constant that represents the ability of a classical vacuum to permit electric field lines. It is also known as epsilon naught. à µ0 8.854 x 10-12 C2/N m2 Coulombs Constant The permittivity of free space is then used to determine Coulombs constant, which is a key feature of Coulombs equation that governs the force created by interacting electrical charges. k 1/(4Ãâ¬Ã µ0) 8.987 x 109 N m2/C2 Permeability of Free Space This constant is similar to the permittivity of free space, but relates to the magnetic field lines permitted in a classical vacuum, and comes into play in Amperes law describing the force of magnetic fields: à ¼0 4 Ã⬠x 10-7 Wb/A m

Regression Analysis - Research Paper Example Introduction In order to check the relationship between benefits and the intrinsic, extrinsic and total job satisfaction, 3 bivariate regressions are run. Using the regression equations the linear relationship between the independent variable (benefit) and the 3 sets of dependent variables (total job satisfaction, intrinsic job satisfaction and extrinsic job satisfaction) is established. Bivariate regression analysis shows how the explanatory power of the independent variable in determining the values of the dependent variable (Malhotra, 543). The results from the regression analysis are explained in details. ... from Excel Regression Statistics Multiple R 0.172306 R Square 0.029689 Adjusted R Square 0.001151 Standard Error 0.352328 Observations 36 ANOVA Ã df SS MS F Significance F Regression 1 0.129141 0.129141 1.040326 0.314948704 Residual 34 4.220582 0.124135 Total 35 4.349722 Ã Ã Ã Ã Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Lower 95.0% Upper 95.0% Intercept 5.1302975 0.179009596 28.6593 2.1E-25 4.766506281 5.4940888 4.76650628 5.49408881 X Variable 1 0.0376321 0.036895473 1.01996 0.31495 -0.03734857 0.1126127 -0.0373486 0.11261267 Graph Key components of the regression analysis Dependent Variable Slope Y-intercept Equation Intrinsic 0.169682348 4.427844793 Benefits= 4.427844793 + 0.16982348*(Intrinsic) 0.16493309 Extrinsic -0.16220711 6.157338158 Benefits= 6.157338158 -0.16220711*(Extrinsic) 0.287582114 Overall 0.0376321 5.1302975 Benefits= 5.1302975 + 0.0376321*(Overall) 0.0296894 Similarities and Differences Similarity: the intercepts of all the thre e regressions are positive and significant at 5% level of significance (as the p-value for all the 3 regressions are less than 0.05) Dissimilarity: The correlation between benefits-total job satisfaction and benefits-intrinsic job satisfaction is positive (as the slope between them is positive) but the correlation between benefits-extrinsic job satisfaction is negative (as the slope between them is negative) The regression results between benefits-intrinsic job satisfaction and benefits-extrinsic job satisfaction is significant at 5% level of confidence (as the p-value for these two is less than 0.05) but the result of benefit-total job satisfaction came to be insignificant at 5% level of confidence. Correlation coefficients The strongest correlation coefficient is between benefits and intrinsic job
