As an initial understanding, regular triangles are achiral in nature while human hands are chiral. Two achiral objects or molecules can be superimposed on top of each other. Several biomolecules within the body exist in one chiral form and the other form is not present. In their quest to determine how chiral objects are formed, they used achiral particles from which chiral structures are formed spontaneously. They employed the technique of lithography to manufacture millions of achiral particles in the shape of a triangle. With the help of optical microscopy, dense systems of such achiral triangular particles were studied which revealed that several of these achiral particles spontaneously arranged themselves into two-triangle super-structures, each of which exhibited a particular chiral form. This is visible by the specific orientations of the super-structures when viewed under microscopy. This discovery lead the team to conclude that biological chirality was the result of the physical phenomena of entropy. This study has shown that chiral structures can form when physical entropic forces act on achiral particles which are of uniform nature. These achiral particles spontaneously form chiral structures through Brownian movement when placed on a flat surface.
While the phenomena of entropy are generally considered to cause disorganization of molecules, however, in this case the interaction of particles at a high density has resulted in an increased ability to move in a regulated manner. This has caused the particles to change into a partially ordered liquid crystal which, in turn, consists of chiral triangular shaped super-structures. With this experiment, the team has concluded that for chirality to spontaneously occur, two physical entities, namely entropy and the physical ...Download file to see next pagesRead More

...change their economic conditions. Certain theorists have even stated that individuals even remain poor as they give up and submit to the culture experienced by the poor class. Individuals who become a part of this culture feel that they cannot change their economic scenario. They give up on the idea of competing and they feel that they are inferior to others and do not have the power to change things around. Sociologists are basically conducting a stereotypical behavior when they suggest that an individual remains poor due to his own activities. This is because not everyone in the poor class gives up or are not future oriented, those who get the option and chance try their best to turn their current economic conditions....

This means that even when a particular party or country for that matter has absolute efficiency and advantage in producing the good or service both can still exist and stand a chance of gaining profits through trade given that they have different comparative competences. Take for instance a case where a worker in country A is able to produce two eggs and eight fish every hour and a worker in country B...

...of almost unbelievable magnitude has been created that continues to worsen in recent months. Thousands upon thousands of individuals have died or been forced to flee war ravaged areas. Accurate death toll and people displaced statistics are hard to come by as the Sudanese government places severe restrictions on foreign journalists' and relief workers ability to access certain refugee camps. Currently, the estimated death toll is extremely high, ranging anywhere from UN Secretary General, Kofi Annan's estimated 450,000 dead, to a lower range of between 200,000 to 400,000 as arrived at by social scientists, John Hagan and Alberto Palloni. Furthermore, these scientists estimate that over a million people have been...

...to save one’s life. As reported by Laura Bassett (2011), “a spokesperson for Catholic Healthcare West, which owns St. Josephs in Phoenix, said the Protect Life Act would not change anything about its current policy, which is to provide abortions only for women whose lives are in danger. But other Catholic hospitals reserve the right to opt out of providing them, depending on the discretion of the bishops that preside over them” (par. 9). The legislative act is definitely precluding the right of the women, not only to decide what is best, but also ultimately, to live. References Bassett, L. (2011, October 11).

...1. What are the tradeoffs of CVS decision to discontinue its sale of tobacco and tobacco related products in its stores? CVS will forgo about $2 billion that would have been revenue from tobacco and related products sales. On the other hand, it will gain a competitive edge over its competitors in getting partnerships with insurers, hospitals, and physician groups (Martin & Esterl par. 7). The move to stop selling cigarettes from its stores will help the pharmacy show its commitment to good health and healthcare and earn it a good reputation with the federal government. 2. Explain how CVS is positioning itself to become a distribution channel for healthcare. By stopping the sales of tobacco and related products, the pharmacy hopes...

For more than 150 years, federal government has been pre-eminent in immigration policy while Congress and the Supreme Court have allowed little room for the regulation of immigrants’ live. Legislation has been restrictive in the past making it hard for the immigrants to live and work well within the American society (Ong Web). Immigration policy has been at the center of the U.S presidential elections especially enforcement between the federal and states and the current policy looks more like a patchwork of...

...Current Events 03/10/14 Sociological perspective refers to the view the society perceives a given society. Society is made up of people who follows different norms and laws that guide them. When these norms are broken, a conflict occurs. The society, therefore, experiences some chaos. In order to understand what sociological perspective is all about, it would be very important for us to consider what the founder fathers of sociology draw them. Then we can use the perspective to define the occurrence of social conflicts and disorders in the society. There are three main categories that define social perspective. One of the categories is symbolic interaction. According to George Herbert Mead, symbolic...
