What is Mercury essays

What is Mercury essays As anyone who's ever broken a thermometer can attest, mercury is a fascinating substance. It also has an interesting history. Named after the fleet-footed Roman messenger of the gods, mercury has been used for more than 2,000 years. Mercury ore cinnabar has even been found smeared on Neolithic skulls. Its first recorded mention is a reference by Aristotle in the fourth century B.C., a time when the silvery-white, heavy metal was used in religious ceremonies. Spanish miners used mercury to process gold ore for ancient Rome; when their mercury supply ran out, gold production dropped and set in motion the decline of the Roman Empire. Today mercury poses a serious threat, this time environmental. Human beings around the world cause mercury to enter the atmosphere primarily when they burn coal or incinerate waste. Studies from Sweden and Florida suggest that mercury also evaporates from landfills, but only 0.0001 per cent. Groundwater contamination from old dumps is of concern but combustion is the major path via which mercury pollutes the globe. Mercury rarely exists in a free state in nature; it's recovered from red mercuric sulphide in geologically recent volcanic rocks. The world inventory of mined mercury is estimated at 600,000 tonnes, stored mostly in states of the former Soviet Union. (Mercury has not been mined in Canada since 1975.) Scientists estimate that man-made mercury releases are two- to four times greater than those of nature. The typical mercury content of lakes has increased up to sevenfold since industrialization. Acid rain dissolves lake-rock and releases mercury to water. (Granite contains about 0.2 p/m mercury.) With a melting point of minus 38.87C, metallic or elemental mercury (the form used in thermometers) readily vaporizes and can be transported long distances. The vaporization rate of mercury doubles with every 10C temperature increase and its residence time in the atmosphere i ...

The Trouble With Business Ethics - Essay Example It was concluded after investigation that Lowry was wrong in her judgment and the reports about Mona Williams were falsely accused. But this lead to the exposure of Lowry herself; and she was terminated from the job and is searching for other jobs outside of Wal-Mart. There are few features that makes whistle blowing a dangerous act for the employees; one of the reasons that employees are afraid to report such behaviors is that they will either lose their jobs or they would be relocated to a different and low profile post. Ethical behavior is one of the key which is taught during the training of the new employees but the credibility of the same is lost because most of the companies which are pro active in ensuring that ethical requirements are met are the companies which were involved in the same crime at one time or the other. The whistle blowing is a tough job to perform because under law a person become liable to report a crime and if he does not report a crime he is as guiltier as the culprit himself. But to announce a crime is not the end rather it’s the means to start of an investigation and legal case and legal proving and so on. These activities take a lot of time of the individual and a lot of family life is ignored; which has even lead to worst scenarios as divorce cases. Few of the employees leave the organization to report such issues; because they are afraid that if they do while they are working they wouldn’t be able to find other suitable jobs in case they are not protected by the company. That is why in most of the cases the ethical issues are not reported and in few the person first secures him/herself with other financial sources before going after the company who might not even take them seriously. The whistle blower are not appropriately protected by the companies; if they would have given the sense of security and trust they would not have

Free Hamlet Essays: Lonely Hamlet :: Shakespeare Hamlet Essays

Lonely Hamlet Hamlet’s decision to keep the murder of his father a secret to himself, along with the betrayals of many of his close friends and family, leads to his eventual downfall. If someone was there for him, whether it was his mother Gertrude, his girlfriend Ophelia, or Rosencrantz and Guildenstern, maybe his timeless death could have been prevented. Instead, his mother sides with Claudius who wants to kill him, Ophelia won’t go behind her father, Polonius’, back to be with him and Rosencrantz and Guildenstern go behind Hamlet’s back and spy on him for Claudius. Gertrude’s blindness to the whole situation is sickening. How she marries the brother of her former husband right after he kills him and never knows the truth is beyond me. She never cared about how her son felt before or after she married Claudius. She didn’t even wait very long after her husband died to get married again ( I; ii; 180-181. "Thrift, thrift, Horatio. The funeral baked meats did coldly furnish forth the marriage tables".). Therefore she is either a very slow, naïve woman or a very evil, coldhearted one. For someone to side with a person even after their own son has told them that the person they’re with has murdered their former lover is absolute lunacy ( III; iv; 29-30. "A bloody deed- almost as bad, good mother, as kill a king, and marry his brother".). Not knowing the truth in the first place is one thing, but turning your back on your own flesh and blood is another. Therefore without his mother on his side, Hamlet has lost all the fami ly in his life that could have helped him get through his terrible time and he sinks lower than ever before. Ophelia’s obedience towards her untrusting father is indescribable ( I; iii; 101-103. "Affection? Pooh! You speak like a green girl, unsifted in such perilous circumstance. Do you believe his tenders, as you call them"?). Why a grown woman would listen to her father and not help the man of her dreams in his time of need is disheartening. A man’s girlfriend should be there for him when a family member passes away, no matter what. If she had been with him on the plan to kill Claudius and knew about his fathers ghost who told Hamlet that Claudius was the one that murdered him, than neither one of them would have went crazy.

Calculation and Report of Wacc of Microsoft

Bonds Microsoft’s long-term debt is composed of eight long-term bonds. It also has two short-term bonds that mature this year and early next year. These bonds were neglected in this report. In this report the required return was calculated by using the coupon rates, market values, time until maturity, and tax rate. These values were all found on Microsoft’s 2012 financial statement. The weighted average cost of debt was then found through the multiplication of each bond’s required return and their corresponding bond weights.These bond weights were found through the multiplication of the quantity of bonds at each interest rate and the market value of each bond; this calculated value was then divided by the total amount of long-term debt, which gives the weights as a percent of the total debt. Microsoft’s total debt was calculated to be lkasdfjl;kasjdf, and the after-tax cost of debt was calculated to be asdfkl;safd. These are logical calculations, since the majority of Microsoft’s bonds do, in fact, have interest rates around 4%.Note, the interest on Microsoft’s bonds is incurred on a semi-annual basis and was calculated in this report on the same basis. Therefore, the semi-annual cost of debt would be half this value: 2%. Some other notes to consider in bond calculations are given below: Do we have any other notes to consider guys? Feel free to message me, and I’ll add them, or add them yourselves if you think there is anything else to include.

Exploited Latin Women

The European conquest of the New World altered the lives of indigenous women. European women did not arrive to the New World only for years after the initial invasions. Indian women were continuously exploited in the form of labor, catering, and sexual gratification. Elite Indian women were able to gain a somewhat privileged position through their liaisons with the European men. As more and more European women began to arrive in the New World, Indian women were confined to the bottom of the ethnic and class hierarchy. â€Å"A particular concern of the colonists was that their â€Å"purity of blood† be preserved, meaning that no black or Indian people could enter into the family lineage. This in return caused careful controlling of women†s behavior. Under the regulation of patria potestad, women remained under the legal authority of their fathers until marriage, when authority was transferred to their husbands.† During the nineteenth century women†s public life was limited. Women also still remained legally minors. There were some advances in education which helped some women to enter into professions. There were also alterations of civic codes which ultimately abolished the patria potestad laws in many countries. Latin American women entered the 20th century with better education and legal status but with still restricted roles. Women initiated campaigns for equal political and civil rights. But despite some gains they continued to be discriminated, shaped by machismo, and poor women faced the double duty of family and employment. â€Å"According to historical records almost 30 percent of households in the city of Sao Paulo in 1765, were headed by women that were single, married whose husbands were absent, or widows. By 1802, this rose to 44 percent, falling to 39 percent by 1836.† This was due to the need of male labor migration in an economy based primarily on plantation agriculture. Taking the average age of female heads it is noticed that the female heads are an average of 7 years older than male heads. Many of the female heads are widows. Female heads earn less income than their male counter parts and on an average have less education than the males. One of the most notable characteristics of today†s poverty in Latin America is the growing number of women among the poor. â€Å"Today about 20 percent of the poorest households in Latin America are headed by women, but in some cities the percentage rises to almost 38 percent. A review of 22 studies of women-headed households in Latin America reveals that there is a strong correlation between female head-ship and poverty, and that such households are increasing in number.† There are many reasons why we are seeing a rise in the number of households headed by women which are in poverty. Women have less access to land, credit and technologies, therefore women farmers have to work longer hours and they have fewer assets and lower incomes than men farmers. Female headed households are likely to be poorer than male-headed households because they have fewer working members of the family, they have lower average wage earnings, less access to jobs and productive resources. Most Latin American women have less education than men. These are some of the key reasons why we are seeing a increase in poor households headed by women. There are more and more women working as wage laborers. † Fruit companies in Chile rely exclusively on women for harvesting, processing, and packing fruit. In Columbia women cultivate and pack flowers. In general they are paid less than men. In Honduras for example women are paid 70 percent of the male wage for performing the same tasks in tobacco cultivation.† It is clear that the women who do participate in the labor force and have the same education level as men are discriminated from men. Discrimination is clearly an important factor. It is not so much that female -headed households have lower incomes because of them having more children or fewer adults, but clearly the head of the household being a female, earns less. Because there are many women who lack education and skills, women in formal sector employment tend to be clustered in jobs that offer little potential for training or advancement. â€Å"In Brazil, Chile, and Peru over 50 percent of economically active women work in the service sector (1988).† Most of the women who do have better paying jobs in the formal sector are self employed. Usually self-employment doesn†t have much growth potential. The problem with women in the workforce doesn†t stop there. In households where there is a male head of the house, a women†s income is still highly depended on. Female income is often a secondary or tertiary source of income. Many rural families rely upon the work of its female members for most of its food. Traditionally the money earned by men is used only for corn and firewood, forcing the wife to develop her own income in order to provide for other family necessities. With less and less land becoming available for cultivation and unable to produce enough corn for the year, the men are forced to find additional income in order to supplement what they can grow. Female economic development has been hampered by the fact that women have found themselves utilizing traditional skills and market connections first established by their mothers and grandmothers. Rarely has a women ventured into learning a new kind of work. â€Å"Complete reliance on traditional skills has limited the economic growth of women.† Women seem to be moving away from the traditional family businesses. Within the last generation the women are going from traditional women†s work to more modern employment. The traditional model is one in which the daughters help their mothers with their family business and in the process learn enough to initiate the same type of business after they marry. The daughter usually starts helping her mother with her business around the age of nine or ten doing small but helpful jobs. By the time the daughter reaches puberty she is a competent and efficient worker. It is at this time that their daughters are a valuable asset. During the daughters teenage years the business is at its peak production. † When the daughter marries at 19 or 20 the mother daughter arrangement ends as the new bride turns her attention to her new home, and then the mother must rely on the younger daughters† to help with the family business. Then the older daughter becomes an asset to her new mother-in-law. The use of family members is very important for their business. Children replace workers that otherwise may need to be hired to run the business. Family members usually are more efficient and the families probably could not bare the financial expense of hired workers. Women in the work force have problems, but they also have problems within their families as well. The female as we have seen is depended on for financial income. At the same time the female has extended responsibilities and concerns at home. Along with working outside the home the female is generally the care taker in raising the children and doing domestic chores around the home. In general the females control the families domestic budget but this seems to be dropping with the rising standard of living of the town. â€Å"Stable marriages are rare, women believe, due to the inevitable failings of men whom they consider to be hopelessly unreliable.† Women of Latin America believe men do their best to live up to their insensitive macho behavior. Men believe they do not need to explain their intemperate behavior. Many Latin American men grow up to expect servitude and obedience from their wives. â€Å"Women are socialized to fulfill their subordinate, long-suffering roles passively, accepting male responsibility, wickedness, and foolishness as their destiny. Thus, women enter into a marital union expecting the worse from their spouses.† â€Å"Expected to succumb to his domination, she is both defenseless and immobilized.† More and more Latin American women with time are acting to protect their own interests. â€Å"More educated women are demanding more equality in marriage through the use of birth control. While they value the maternal role they are understanding the rising costs of having children and want more from the marital relationship than motherhood. They want their husbands to respect and trust them, and to forego extramarital affairs and other forms of abuse.† Today in Rio de Janeiro there are five police stations that exist solely to handle crimes against women. â€Å"While Brazil has advanced from military dictatorship toward democracy violence against women remains endemic. The first national study of the problem, in 1992, reported an average of 337 assaults on women daily.† Feminists in Brazil in 1985 made a serious gain with the establishment of the women†s police stations. Feminists moved for this because they believe male policemen don†t take wife beating seriously. â€Å"They see it as a domestic argument that has nothing to do with them and is certainly not a crime.† On paper, Brazil†s women have made great gains in recent years. The country†s 1988 constitution bans discrimination against women, requires the state to combat violence against them and mandates 120 days of maternity leave. In reality there still remains traditional theories of women†s behavior and much discrimination.

Co-Dominance in Evolution

Co-Dominance in Evolution Co-dominance is a type of non-Mendelian inheritance pattern that finds the traits expressed by the alleles to be equal in the phenotype. There is neither a complete dominance or incomplete dominance of one trait over the other for that given characteristic. Co-dominance would show both alleles equally instead of a blending of the traits as is seen in incomplete dominance. In the case of co-dominance, the heterozygous individual expresses both alleles equally. There is no mixing or blending involved and each is distinct and equally shown in the phenotype of the individual. Neither trait masks the other like in simple or complete dominance, either. Many times, co-dominance is linked with a characteristic that has multiple alleles. That means there is more than just two alleles that code for the trait. Some traits have three possible alleles that may combine and some traits have even more than that. Oftentimes, one of those alleles will be recessive and the other two will be co-dominant. This gives the trait the ability to follow the Mendelian Laws of heredity with simple or complete dominance or, alternatively, to have a situation where co-dominance comes into play. Examples One example of co-dominance in humans is the AB blood type. Red blood cells have antigens on them that are designed to fight off other foreign blood types, which is why only certain types of blood can be used for blood transfusions based on the recipients own blood type. A type blood cells have one kind of antigen, while the B type blood cells have a different type. Normally, these antigens would signal that they are a foreign blood type to the body and would be attacked by the immune system. People with AB blood types have both antigens naturally in their systems, so their immune system will not attack those blood cells. This makes people with the AB blood type universal recipients due to the co-dominance displayed by their AB blood type. The A type does not mask the B type and vice versa. Therefore, both the A antigen and B antigen are equally expressed in a display of co-dominance.

Push and pull factors are those which compel or stop a person from migrating from a rural setup to urban setups respectively. The three most common push factors are famine, unemployment and poor living conditions. Famine causes lack of food, income and employment whereas poor living conditions make people thinking of the better facilities available in urban setups. These factors contribute majorly in making a person think about leaving his village and working in an urban environment which attracts him with these factors are known as the pull factors. The most common pull factors are known to be employment, better income-to-work ratio and urban facilities available in a city like medical care and better schools for children. There are many ways in which water can be conserved but broadly it can be divided into two parts namely engineering methods and domestic methods. Some of the engineering practices that are useful in conserving water are plumbing. Many practices fall under the plumbing category for example the use of low flush toilets and pressure reduction techniques. The next sub-category engineering methods may be named as landscaping in which technique known as landscape irrigation is regarded as the best. In this method plants with lower water needs are used as well as grouping plants together which have similar water needs. This factually saves a whole volume of water. Domestic methods are those which can be inculcated in the everyday behavior trends of people in their daily life. The most common way of saving water by daily users are: ENSO is an abbreviation for El Nino Southern Oscillation. As a result of ENSO there is a decline in the amount of rainfall in Australia. In Indonesia, the early ENSO causes dryness where as in the later phase causes
