The formula for this reaction is:C7H6O3 C4H6O3 → C9H8O4 HC2H3O2.How many grams of salicylic acid are needed to make 1000 1-gram tablets of aspirin? (Assume 100% yield) Solution Step 1 - Find molar mass of aspirin and salicylic acidFrom the periodic table:Molar Mass of C 12 gramsMolar Mass of H 1 gramsMolar Mass of O 16 gramsMMaspirin (9 x 12 grams) (8 x 1 grams) (4 x 16 grams)MMaspirin 108 grams 8 grams 64 gramsMMaspirin 180 gramsMMsal (7 x 12 grams) (6 x 1 grams) (3 x 16 grams)MMsal 84 grams 6 grams 48 gramsMMsal 138 gramsStep 2 - Find mole ratio between aspirin and salicylic acidFor every mole of aspirin produced, 1 mole of salicylic acid was needed. Therefore the mole ratio between the two is one.Step 3 - Find grams of salicylic acid neededThe path to solving this problem starts with the number of tablets. Combining this with the number of grams per tablet will give the number of grams of aspirin. Using the molar mass of aspirin, you get the number of moles of aspirin produced. Use this number and the mole ratio to find the number of moles of salicylic acid needed. Use the molar mass of salicylic acid to find the grams needed. Putting all this together:grams salicylic acid 1000 tablets x 1 g aspirin/1 tablet x 1 mol aspirin/180 g of aspirin x 1 mol sal/1 mol aspirin x 138 g of sal/1 mol salgrams salicylic acid 766.67Â   Answer 766.67 grams of salicylic acid are needed to produce 1000 1-gram aspirin tablets.

How to be a good mentor

How to be a good mentor Those of us who have had the opportunity to have a good professional mentor as we travel through our career paths are well aware of the value they bring- this includes everything from support, encouragement, and motivation; to opening new doors; to networking and job opportunities. The bottom line is that a good mentor is really worth their weight in gold.   That said, others among us have learned that some people who find themselves in a position to be mentors are really not well-suited for the role and can even do more harm than good. A bad mentor can hold you back from new opportunities and career advancement, set you off on a trajectory that isn’t right for you, and even sour you on an industry entirely.Clearly, the role of a mentor isn’t one to be taken lightly. It’s a tremendous responsibility, and one that could potentially give you a great deal of power and influence over someone in need of real advice, molding, and guidance. If you’re making a c onscious decision to become a mentor to someone junior to you in your field, make sure that you enter the role with every intention of being a positive influence. Consider using the following strategies to get started on the right foot.3 rules to being a strong mentorDon’t feel threatenedHere’s the raw truth when it comes to most mentor/mentee relationships: you’re helping to train the next generation of workers in your field, and they’re going to be just as ambitious as you likely were when you were just starting out and eager to climb to the top of your career ladder as quickly as possible. Take a moment to look back on those times- didn’t you have visions of eventually seizing the reins of power and filling your boss’s shoes (hopefully as they quietly shuffle out of your way)? Chances are if you’re mentoring someone they’ll likely be harboring the same ambitions.Don’t let this cloud your relationship with them or make you feel threatened and defensive- or worse, make you work against their best interests. Instead, recognize that this is a natural part of the professional cycle. As older employers mature, new employees will enter the field and hopefully gain the necessary skills and experience to one day take control. It happened for you, and one day it’ll happen for them; after all, you won’t be in the world of work forever and likely don’t want to be. The best you can do as a mentor is to help ensure that you’re placing the future of your company and industry in capable hands.Don’t do it for personal gainIn the world of work, most of us are used to the sort of â€Å"quid pro quo† arrangement where both sides get something tangible when taking part in a mutually agreed upon transaction. However, the mentor/mentee relationship is a little bit different. The fact of the matter is, there’s an inherent imbalance (of sorts) when it comes to â€Å"who gets what† here; the mentor typically devotes a significant amount of time and energy to the exchange and the mentee reaps most of the benefits- the knowledge, skills, experience, and opportunities that you’re passing along to them. It is true that mentors get the satisfaction of knowing that they’re â€Å"paying it forward† and helping out the next generation, but make sure that that’s enough of a return on your investment when deciding whether or not to be a mentor. Do it for the satisfaction of helping pave the way for someone else, and not for personal gain.Check yourselfAs we said before, becoming a mentor is a big responsibility and not one to be taken lightly. You’re going to have a real impact on the life of someone in a dependent and impressionable time in their life, so make sure you have enough time and energy to do it well. There’s nothing quite as dispiriting as having a mentor who never seems to have the time to work with you and who you’re always chasing down for help and guidance- or worse, who seems annoyed or put out by your needs. Don’t be that sort of mentor- if you commit to doing it, make sure you’re doing so with the understanding that you’re going to have to carve out a significant amount of your time and resources towards being a good and reliable source of support and guidance all the way through.Being a mentor can be a challenging role, and often the rewards aren’t immediately tangible. However, when done properly, being a positive mentor to an eager and excited individual can be an extremely rewarding and fulfilling experience. If you’re going to be a mentor, then commit to being a good one, and use the strategies and advice presented here to help you along the way.

Investing in SME's in developing countries. Discuss different facets Essay

Investing in SME's in developing countries. Discuss different facets associated with these investments (from the perspective of - Essay Example There has been an upward trend in the acquisition of private equity funds due to a number of reasons. Apart from the high returns on investment, small and medium enterprises take up private equity because the markets have been liberalized to free market economies and there is proper disclosure and financial reforms that enable transparency to be experienced at the time of investment. PE funds also enable companies fill the gap in finance in the self-financing of the company and obtaining funds from other sources. Small and Medium Enterprises (SMEs) Small and medium enterprises (SMEs) have numerous definitions with each country having its own distinct definition depending on its own unique economic patterns. However, most countries base their definitions in the number of employees, value of assets or the annual turnover for a firm to qualify as a small and medium enterprise. For example, the European Union states the limits for the number of employees in SMEs to be between 200 -250, w hile Japan sets the limit as 300 employees. This starkly contrasts with the situation in USA whereby SMEs are those enterprises with about 500 employees in the firm (Murphy 7). According to the World Bank, small and medium projects are those businesses with workers not exceeding 300 in number with a yearly income turnover of $ 15 million, and resources that are valued at $ 15 million. Data made available by Organization for Economic Co-operation and Development (OECD) show that almost 100% of business entities or enterprises within the grouping are small and medium enterprises accounting for 60% of employment in the private sector thereby making a substantial contribution in the development of economies of most developing nations. Developing nations define SMEs as groups of businesses that is composed of a mixture of self-employed or enterprises that have less than 10 employees and they are often found in informal sectors of the economy. The SMEs are regulated through certain princi ples that allow them to thrive in any given market. These principles include the proportionality principle that establishes an appropriate comparison or balance between risks and costs and their impact on the regulation of the business. This ensures that there are no needless or unnecessary demands placed upon the business in its regulation. The policy objectives must be transparent, clearly defined and communicated to the SMEs so that they know their prime objectives and obligations and make them aware of the expectations from the regulatory authorities. There must be accountability in the preparation of proposals and consultation before the making or taking of decisions. SMEs do well in environments where the policies put in place are consistent in application. SMEs are important in the economies of developing nations in that they provide the important revenue that translates to more tax by specific nations. They also contribute to the creation of employment opportunities and reve nue generated from exports. They are however restricted in the acquisition of funds as often, they possess little information that may be required to access funds from example bank loans. This has made such kind of enterprises to resort to private equity funds that is fast gaining ground in the world’

Joshua Bearmans story Art of the Steal Essay Example | Topics and Well Written Essays - 750 words

Joshua Bearmans story Art of the Steal - Essay Example This paper illustrates that Gerald Blanchard always prepared to make his heist by investigating flaws in the security system akin to an individual’s identification of dry leaves on a tree. Effectively, proper planning and a thorough investigation always ensured Gerald’s stealing activities were an enormous success. It is pertinent to note that, Gerald started his exploits at a young age. In this regard, he had managed to become a local criminal mastermind in his neighborhood while in high school. The story Art of the Steal elucidates the escalation of his sophistication based on his shrewdness in technology formed over time from an early age. Thus, the story gives his exploits from parachuting in, changing jewels secured by a weighted alarm, and many more intriguing stories including well-organized getaways. On the other hand, his flaunty nature was a contrast to a mastermind of some of the most sophisticated crimes committed. Eventually, this behavior eventually led to a mistake that led to his arrest and consequent sentencing whereby he served a jail term. Despite the book being about acts that are criminal in nature, there are many positive lessons that individuals can draw from Gerald’s epic tales and apply them in life. First, good cognitive skills are one of the factors that contributed to Gerald’s success during his exploits regardless of the security mechanisms in the places he targeted. Cognitive skills are crucial in our daily lives to make the decisions. For example, Gerald parachuted onto the roof of the Vienesse Castle on his way to steal the Sisi Star. During the tour of the castle, Gerald realized that â€Å"There was an armed guard stationed at every entrance and patrolling the halls but the roof was unguarded†. In this case, it would take an individual with a good perception, quick learning, and reasoning to formulate the only easy way to get into the castle. Evidently, Gerald had these important skills since he figured out the easy way to get into the building and carry out the heist was through parachuting onto the unguarded roof of the castle.

The Shichi Go San and the Marimo Matsuri Festivals Essay -- pray, autum

Fall is the time for letting go of the old ways and bringing in the new life. Autumn is also the period where one harvests their desire to learn. Autumn is the time for departure but having already fulfilled in wisdom and maturity. Fall is also the time to be thankful for all the things that occurred in your life. In Japan, the fall festivals are a way for the people to pray and be thankful for the harvests. Some festivals that occur in Japan during this time of the year are: Marimo Matsuri, Nada no Kenka Matsuri, Sichi-Go-San, Tori no Ichi, and the Kawagoe Matsuri. To begin with, the Kawagoe Matsuri in the Saitama prefecture occurs on the third Saturday and Sunday in October. The main attraction of this festival is the floats that are pulled around the city. The largest highlight of this festival is the Hikkawase. This is a musical competition between different festival floats. The people perform a hayasi performance, which is a traditional Japanese orchestra of different instruments, such as the flute and drums. The floats that you might observe at this festival are called Edo-kei Kawagoe-gata, and they were usually built by the craftsmen in Edo and Kawagoe. These floats are about two stories high with a doll place on top. The Kawagoe Festival usually takes root from the Jinkosai festival, where elaborately decorated shrines are carried throughout the neighborhood.

Otherness

Cheyanne Easter Processor: Temple English 066 1 October 2012 Otherness Everywhere you go you catch yourself either stereotyping or being stereotyped just by the simple she lives in a big house she must be rich or he’s Asian he must be good at math. Stereotyping is usually a negative habit on all human beings but it somehow weasels its way into social acceptance. Now, more than ever and somehow we end up accepting it with no concern.Allport (1954) theory was that thinking ill of others without warrant that people make their mind u' without any personal experience. This pre judgment is worldwide it happens everywhere including every race white, black, Hispanic to what gender female or male. We are all human we all do it. One group we tend to target the most, our middle aged black men, we pracive them to be a gang member or drug dealers by their own appearance. But would it be wrong to say that hip hop may have an effect on the way people look at African American men in our socie ty.While watching an episode of the Tyra Banks show rerun an episode about stereotypes happened to be on where Tyra did an experiment where she put a group of people from all backgrounds showed them a picture of different cultured individuals and asked what and how you felt about them just by their appearance. The first picture appeared of a middle aged tall black man wearing baggy jeans, boots and an oversized jacket. People assumed right off that bat that he must not be educated, he must be on welfare trying to support his kids and baby momma was some white female’s exact words.These comments were even coming from the same race â€Å"that he must be strapped with guns and running the street as a gang banger† one African American women stated. It was sickening for people to make all these assumptions just based on their theory of stereotypes by a certain individual. He was later brought out face to face with these people to find out that he’s a very successful antrapranoer and has already earned 4 degrees. He says it the same reaction he gets from individual all the time, â€Å"it’s hard on me and that everything I’m hearing today I have to carry the weight of every African American male out there†.He explains that those type of stereotypes are the ones he has to live up to on a daily bases. You could relate this man’s experience with a young African American boy that was murdered because this man thought he was being â€Å"suspicious†. Trayvon Martin a 17 year old teenage that was shot for the simple fact that he was a black male wearing a hoodie walking through a gated neighborhood. Federals say this could indeed be a hate crime. What went through George Zimmerman’s head to shoot this innocent boy was it the first time Zimmerman’s done such type of prejudgment on black males, no.At the very least, a situation of 46 emergency calls made by Zimmerman over the past six years documents his at tentiveness about keeping his neighborhood safe and orderly. The calls include complaints about unruly people at the pool, potholes, dumped trash, and kids playing in the street. In recent months as the neighborhood saw an uptick in crime, including burglaries and a shooting, Zimmerman's calls had focused on specific suspects, the majority of them young black males.Zimmerman assumptions about these people made them his target. Some people say that this doesn’t exist in current day society but this right here is a prime example. To willingly kill a young black kid due to the fact that he walked into this residence or for the simple fact that he was cutting in-between houses, walking very leisurely for the rainy weather and looking at all the house gave Zimmerman the right to shot this innocent kid that caused death by his own prejudgment it devastates me to the bare bone.This problem will never stop. People tend to fill their head with what they want to believe. Is it wrong to say that maybe† hip hop† had a little influence on the killing of Trayvon Martin, editor in chief of GlobalGrind. com, a site about the â€Å"hip-hop† side of pop culture said â€Å"Even if I have a black hoodie, a pair of jeans and white sneakers on, in fact that is what I wore yesterday, I still never will look suspicious.No matter how much the hoodie covers my face or how baggie my jeans are, I will never look out of place to you,† he wrote. â€Å"I will never look suspicious to you, because of one thing and one thing only,  the color of my skin. † Thus, clothing lines and particular clothing items popular within the hip hop culture are Stereotyped and ignoring simplistic understandings of hip hop culture lead people to assume the role of a ordinary African American that lives day to day in our society , as drug dealers, gang bangers or want to be rappers.Do hip hop rappers influence people to assume that black men aren’t safe to be arou nd if they portray the image of rapper, is it all about getting money, smoking and having a gun. It’s sad to say these stereotypes can just come from material clothing you not only see it in hip hop fashion but in the holocaust people could see right through you that you were a Jew, during this semester we’ve been reading a book called Maus were it takes you into the life of one Jewish man valdeck spingleman that survived the worst externmation of 11 million people.

Conceptions of women and the foreigner Essay

In the ancient Greek life, women’s role was always considered to be quite insignificant as compared to the role of the Greek men. However, in most tragedies women were the major and integral characters who revealed some insights on the way the women happened to be treated and also thought in the entire society. Medea is maybe the most complex and fascinating character when we look closely to the Greek’s drama. She is an immense and an ultimate mixture of villain, heroine as well as the victim as displayed in the play. She was married to Jason who was a Greek man who she had decided to follow from the foreign land. Her love was deep and when Jason decided to leave her in order to marry Creon’s daughter she was extremely furious (Euripides1907, lines. 1-24). From there we see her getting involved in some acts of revenge. Her acts of murder are the ultimate start of revenge towards her children and her ex-husband. Despite all this catastrophes, Medea is a character to sympathize with. She decided to give up all that she had because of her love for Jason. She betrayed her family and murdered her brother, she left her home because of the love she had for Jason to a foreign land and she became a mother to please his husband yet she had no any desire to have children (Euripides, 1907,line,248). Even after Jason had known of all the sacrifices that Medea had had for him, he still had to leave her for a Greek princess. Medea’s love was quite immense and Jason’s betrayal ended up damaging her mind completely and revenge became the only comfort that she had in her power. She ended up killing the Greek princess using the cleverest chess that was available and her children. Though Medea is portrayed as one of the most frightening characters, it is crucial to compare her ethical concerns and the scheming shallow hollows of her ex husband. Medea accompanies her Antigone as the most defining heroines in the ancient Greek drama. She ended up defying her main role as the helpless and happy housewife and refutes to accept betrayal without revenging. Medea decided to abandon all the gender roles in the ancient society of Greek. She defied some perceptions of gender through portraying both female and male tendencies. She decided to detach herself from all the womanly emotions and acted in a way that the society did not see appropriate for women. In the ancient Greek, murder was an issue that was never associated with the women though Medea in the play committed a series of murder including her own children (Euripides, 1907, 207-213). It is therefore imperative to analyze at length the concepts of women and the foreigners in the Greek tragedies basing the rationale as portrayed by Medea. In the play, Medea is portrayed as a foreign witch. She is treated irrationally throughout the play by various people at divergent times. She then changes her whole character and finally triumphs over Jason. She is feasibly seen as the mortal woman and Aristotle’s hero figure as well as the goddess. Women’s rights have been neglected throughout the play and women have no voice. Medea changes all that in her revenge against Jason and her own children. Foreigners and women were loathed and had no any place in the society and were not supposed to have any powerful position. It is a play portraying chauvinism, women treated unfairly and their work portrayed as only meant to bear children. Though to an extent we see the evil deeds of Medea, we also have a glimpse on the reasons behind her deeds. She is a foreigner and to the Greeks she will always be a Barbarian. Her acts make it even hard for her as she gets hated more. Even other women treat her suspiciously. Medea is portrayed as a foreigner in her land and in her own home who has no any common feature with the Corinth women. All she had was Jason and the children. Before she got married she was viewed as a princess and later became an outcast. Women and foreigners in the Greek tragedy were portrayed as disenfranchised, slaves and were unrepresented. The acts of Medea have contradicted the view of the society that the women are the main givers of life and that the men end up taking it away. It is quite unacceptable because of the fact she is the mother to the children. Killing a member of the family was usually frowned upon in the ancient Greece like it is done today. Medea has portrayed extreme pride which is usually stereotyped as one of the characteristic of the male species. She decided to sacrifice all that she had even her reputation in order to restore her own reputation (Sophocles, Euripides & Aeschylus, 2004). It has always been a common belief that the major weakness in a woman is the children but in this case this is not so. Her pride has prevailed other maternal instincts. Medea aims to seek vengeance in the same intense force to rectify a situation just like a man would. A woman who is seeking for revenge usually challenges the societal views of women as passive and weak. Medea is dwelling on self pity until she contrives to a scheme that will avenge how much she has been hurt. Wallowing is usually a quality that is attributed to the women in the society. Medea was so sad with her life after her marriage to Jason ended that she only wanted to die. The common opinion in the society is that the women usually use trickery and deceit in order to achieve their main goals in life. Medea in this case is not an exception as she persuades Creon to permit her to stay at least one day in Corinth as she pretends that she is preparing for exile while in the actual sense she was just planning on how she will carry out the murder acts to her enemies as well as children (Euripides1907, pp. 198). Medea in the entire play has defied the stereotypes of both female and male characters. She has shown some immense emotions portrayed by both sexes. At times she acts as an ultimate man and others as a woman. The Greeks had an immense suspicion when it came to foreigners and always thought of all of them to be barbarians. With Medea, Euripides has confronted this prejudice issue by deciding to honor foreigners with some roles of a tragic heroine and making her one of the most intelligent character in the entire play. The playwright has also confirmed numerous Greek stereotypes of the foreigners through making Medea overly passionate, wild and vengeful. Medea is a very powerful and tragic heroine who gets to achieve successful vengeance and ends up escaping with impunity. In some scenarios, she is portrayed to be a submissive and weak who commits no any crime (Paul, 2006, pp. 1321-4853). Allan (2003, pp. 143) asserts that beneath Medea’s personality there lies a credible, coherent and an effective character who portrays an immense sense of justice and whose humiliation and revenge drive her to go for the revenge. He also notes that Medea’s actions and plans were affected by her main status as a foreigner and a woman and not as a mortal avenger. Euripides in his play is fascinated by the acts of women as well as the contradictions that do exist in the Greek understanding of the term gender. His treatment of the women is so sophisticated. Medea’s starting speech to the chorus is the most rational and eloquent statement on the injustices that befall the women species. He recognizes that the major position of the female and their style of subordination to men are coming from the social order that prevails in Greece. Medea is not really a role model as far as feminist is concerned. Euripides has portrayed the difficulties that women went through. He portrays an image of a real woman who has suffered and has been twisted by her suffering. It is not a story on women liberation but rather it is a war that exists between sexes. The other key is a major theme. Medea’s foreignness has been emphasized from the beginning. In the very first opening lines, the nurse reminds us that Medea is from an exotic and a distant land. The foreignness aspect is portrayed as barbaric, exotic, fearful and unknown. The issue of exile has also been portrayed in the play. Modern readers and audiences have a great difficulty when trying to conceive on the concept of exile and how much it was horrible for the Greeks. Homes and cities were considered as the major source of protection. Wandering with no friends and shelter was seen as a great fate which was much horrible than death itself. Medea just for the sake of husband made herself to be the exile. She goes away from home, have no friends or family who can offer protection to her. The theme of exile has been linked with women’s position. In emphasizing some of the circumstances in which women have to bear after marriage like leaving their homes and staying with strangers. Medea reminds us of the worst conditions in exile. Her position is a grave situation since she is already an exile in reality and portrays the fact that all women in reality are exiles. She is a foreigner thus to all the Greeks she will always remain a barbarian. In the play the issue of cleverness and cunning is also evident. These traits though they ought to be admired cause a lot of suffering to Medea. Her intellect, force and strength exceed her station of operation. Though the Greeks to an extent have some respect for her, they are seen treating her smugly just because she is a woman and a foreigner. She is surrounded by some people who are less resourceful and less intelligent than her. She is despised because of her own talents that ought to have won her praise. Since she is a foreigner she therefore behaves without morality and any restraint. In the chorus, we see how much Medea is pitied but also it reveals that women ought to endure. We see Medea entering and delivering a monologue on the sufferings that women go through. Though women are creatures that can feel and think, they have to endure some indignities in the society. Men are meant to bear arms but women are supposed to bear children (Medea 214-224, 2006, pp. 115). The theme of women and their position has been emphasized in the play. To just allege that Euripides was a great feminist can only be a major oversimplification and anachronism. What is factual is that Euripides is fascinated by the difficulties and women’s position. Through examining the treatment that women are accorded, Euripides has also revealed some of the injustices in the society. He is savvy of how art has been wrongly used in defaming the character of women and how smart it has been used in recognizing that most fables and myths of the Greeks male dominated orders through teaching women on how to accept as well as enjoy subjugation. Medea who is a woman and a foreigner has portrayed numerous specifics of the life of Greeks that are universal in today’s society. A woman when she gets married ought to leave her home in order to join her own family. Therefore she is portrayed as an outsider. Women are not meant to socialize freely as men, while men can roam wildly and indulge with other women. Medea has made herself as the main spokesman on the suffering of women thus has secured the secrecy and loyalty of the main chorus. Foreigners were people who were disliked in Greek. In the play we see how much King Aeetes’s hated the foreigners. â€Å"A great anger filled King Aeete’s heart as he listened. He did not like foreigners, any more than Greeks did, he wanted them to keep away from his country, and he himself said to himself, â€Å"if these strangers had not eaten at my table I would kill them† (Jimmison, 2009). The image of Medea and the barbarian king was irrational, magic, frightening and issues to do with some supernatural powers had no any place in the Greek mythology. As a foreigner, Medea only expected suffering since this myth was created in the Greek image of a Barbarian woman. Medea has shown numerous heroic qualities that were uncommon among the Greek women. She is even willing to kill her brother just to be with Jason. In Greek, women murdering acts were quite rare and this is something that was not supposed to happen at al. To some extent, Medea is reacting to the inferior status of injustice that women were accorded. Central to the entire plot, is Medea’s foreign origins and how they are really related to her main actions. Generally women in the play have been portrayed as creatures with very few rights. As far as men were concerned, women were only supposed to cook and clean, do some house chores and bear children. They had no imperative votes like the right to own property, vote or choose their own husbands and they had to be presented in any legal proceedings that were taking place. They were just like slaves. Though some of Medea’s actions were untypical of what a Greek woman was supposed to possess, to some extent she also had emotions and attitudes of a common woman. She speaks against some of the women’s rights and how they have no any choice to whom they decide to get married to and men can get rid of a woman in order to get whatever they wanted (Euripides, 1907,pp. 231-247). In the play we see Medea portraying some emotional attitudes of a woman and a mother. She says, â€Å"Poor heart, let them go, have pity upon the children (Euripides, 1907,pp, 1057). Also in the play women are portrayed as faithful. Medea talks of how she helped her ex husband during his quest of the Golden Fleece and even helped him to escape to an extent of killing his own brother for him (Euripides, 1907,pp. 476-483). The fact that she decided to betray her family just to be with Jason shows her sense of loyalty. Though women and foreigners were portrayed as minorities with no say, the play also shows that they were resourceful and clever. Instead of using physical force in accomplishing her plans of revenge, she went ahead to use her mind instead. She asserts, â€Å"it is best to †¦ make away with them with poison† (Euripides, 1907,pp384-385). She poisons Jason’s wife as well as the King of Corinth though she poisons them indirectly. Medea’s act of murder against her own children is because of her barbarian origins. The major reason why Jason decided to let go of Medea and marry a princess is in order for her to have a higher status and material wealth through getting married to the king’s daughter (Euripides, 1907,pp553-554). It is lucid hence to note that Jason had a belief that Medea’s foreign origins were a burden and a distracter to him since there was a stigma that was related to that. Medea’s foreign status is also a major burden to her. Once they got separated, she became an outsider and had no any place to go since barbarians were never highly thought in the Greek society. If Medea was not a foreigner, then it is possible that Jason would not have divorced her. Medea is a play that portrays the real ancient Greeks and their attitudes towards the foreigners and women. Women were supposed to be seen and not heard and thus Medea surprises the Greek society since she goes against the norms. Women were supposed to bear children and take care of their husbands. The women’s rights were less considered and there was no way women could equal men. The foreigners had no any right and were also treated unfairly. It is a play revealing some of the heroic acts of women and what they had to go to get noticed in the society. Works Cited Allan, William. Euripides: Medea. 2002.

De Broglie Wavelength Hypothesis Overview

De Broglie Wavelength Hypothesis Overview The De Broglie hypothesis proposes that all matter exhibits wave-like properties and relates the observed wavelength of matter to its momentum. After Albert Einsteins photon theory became accepted, the question became whether this was true only for light or whether material objects also exhibited wave-like behavior. Here is how the De Broglie hypothesis was developed. De Broglies Thesis In his 1923 (or 1924, depending on the source) doctoral dissertation, the French physicist Louis de Broglie made a bold assertion. Considering Einsteins relationship of wavelength lambda to momentum p, de Broglie proposed that this relationship would determine the wavelength of any matter, in the relationship: lambda h / p recall that h is Plancks constant This wavelength is called the de Broglie wavelength. The reason he chose the momentum equation over the energy equation is that it was unclear, with matter, whether E should be total energy, kinetic energy, or total relativistic energy. For photons, they are all the same, but not so for matter. Assuming the momentum relationship, however, allowed the derivation of a similar de Broglie relationship for frequency f using the kinetic energy Ek: f Ek / h Alternate Formulations De Broglies relationships are sometimes expressed in terms of Diracs constant, h-bar h / (2pi), and the angular frequency w and wavenumber k: p h-bar * kEk h-bar * w Experimental Confirmation In 1927, physicists Clinton Davisson and Lester Germer, of Bell Labs, performed an experiment where they fired electrons at a crystalline nickel target. The resulting diffraction pattern matched the predictions of the de Broglie wavelength. De Broglie received the 1929 Nobel Prize for his theory (the first time it was ever awarded for a Ph.D. thesis) and Davisson/Germer jointly won it in 1937 for the experimental discovery of electron diffraction (and thus the proving of de Broglies hypothesis). Further experiments have held de Broglies hypothesis to be true, including the quantum variants of the double slit experiment. Diffraction experiments in 1999 confirmed the de Broglie wavelength for the behavior of molecules as large as buckyballs, which are complex molecules made up of 60 or more carbon atoms. Significance of the de Broglie Hypothesis The de Broglie hypothesis showed that wave-particle duality was not merely an aberrant behavior of light, but rather was a fundamental principle exhibited by both radiation and matter. As such, it becomes possible to use wave equations to describe material behavior, so long as one properly applies the de Broglie wavelength. This would prove crucial to the development of quantum mechanics. It is now an integral part of the theory of atomic structure and particle physics. Macroscopic Objects and Wavelength Though de Broglies hypothesis predicts wavelengths for ​matter of any size, there are realistic limits on when its useful. A baseball thrown at a pitcher has a de Broglie wavelength that is smaller than the diameter of a proton by about 20 orders of magnitude. The wave aspects of a macroscopic object are so tiny as to be unobservable in any useful sense, although interesting to muse about.

Consumer protection Essay Example | Topics and Well Written Essays - 2000 words

Consumer protection - Essay Example f acts of parliament have been established to ensure the protection of the consumers and ensure that government agencies follow established standards. The English tort and the English contract law were the first established acts that were established to ensure the consumer protection in the country remain stable. A number of departments have also been established including the department of trade, industry, price, and consumer protection. The establishment of European community’s act of 1972 also enhanced the country’s effort to protect the consumers from illegal and exploitative business practices (Jay & Clarke, 2010). Despite the massive development in consumer protection law in the United Kingdom, the effort to protect consumers from poor processed products and exploitative business practices has met a number of challenges. In this paper, the challenges of the efforts adopted in the United Kingdom to protect the consumers will be discussed. The paper will also highlight the methods that are used by the consumer rights bills to overcome consumer protection challenges (Cartwright, 2008). The consumer rights bill was recently introduced to the United Kingdom parliament for deliberation, enhancement and possible adoption after passing through the House of Lords. This bill is believed to have the power to streamline the consumer protection efforts in the country and update retrogressive consumer protection laws. Based on the consumer rights bill, consumers have core rights, which must be respected by other businesses and legal entities in the country. These include the right to be paid and enjoy goods and services which meets the established standards. Consumers also have the right to fault the products and services they buy and to expect a refund or replacement in the event that the producer is at fault. The consumer rights bill is currently before the House of Lords in the country’s legislature and expected to be ratified and adopted by the country.
