Chapter 2 - Essay Example nderstanding with respect to the way in which solar energy represents a potential to serve as an effective form of renewable energy in the coming decades. Solar energy is one of the most promising forms of alternative energy that is yet to be explored to its full potential. However, alternative energy could not be used without an understanding of some specific requirements, such as, geographical location and policy (Goh et al, 2014; Liu et al., 2013). Yet, regardless of the promise that solar energy seeks to provide, the fact of the matter is that it still represents a litany of drawbacks; drawbacks that will be discussed at some depth further in the analysis. For this very reason, individuals are necessarily discouraged from using it and the level of research that takes place is limited with respect to the means by which this energy is stored after it is collected. However, with all that being said, it must also be understood that this is still a relatively new technology. Within these lines, it can further be expected that developments in solar energy could necessarily lead to a breakthrough in which it could reduce or entirely negate many of the negative drawbacks that have thus far been evidenced. It is of no question that technology has heavily impacted the way in which processes take place within the modern world. The changes in technology over the past hundred years have been profound; giving of mankind the ability to fly, orbit the Earth, visit the moon, create the Internet, build the computer, and perfect the internal combustion engine. Nanotechnology is a topic that has a high level of relevance with respect to the development of the world. Essentially, nanotechnology refers to the manipulation of matter; either in the atomic, molecular, or super-molecular state (mnyusiwalla et al, 2003). In such a way, the developments within this sphere could vastly contribute to the increased efficiency of different processes; even going so far as to ensure that

Poverty in India Essay Example for Free

Poverty in India Essay With 44 percent (44%) of the global outsourcing market in the off shore sector for software and other business process currently being hosted by India, it has fast gained global recognition as the premier global destination for business process outsourcing.   With generated revenues totaling over US$ 17.2 billion and employment related to outsourcing at 1.05 million as of March 2005, India has greatly increased its economic output and per capita GDP.   This economic growth of India has been heralded as one of the most amazing success stories of the 20th century.   The growth rates that India has been posting over the past five years have made it one of the reasons why investments have risen in the area. The problem is that even with the robust economic growth of India the schism between the rich and the poor continues to grow.   Outsourcing, while creating a boon for the Indian economy, has also intensified that gap by creating new social classes and spawning new cultural changes.   Therefore, because of the weak economic fundamentals of the Indian Economy, instead of narrowing the gap between the rich and the poor, it is instead widened and fewer jobs are created thus leading to more widespread poverty. The greatest problem that these poor fundamentals present to society however is the widening of social divisions that are already existent in society.   In the Indian model the social rifts that are created deal with the differences from within the family unit in relation to the outside society.   The creation and birth of a new type of middle class society which is predominantly comprised of members of the youth sector is creating a class that is being socially and culturally alienated from the rest of society, particularly in the traditionally conservative Indian society. New work habits and consumer patterns have created a new class that enjoys the more expensive and extravagant lifestyle that is supported by the relatively high wages that receive as compared with the rest of Indian society.   There is very little time to spend in the household where more solid and fundamental values are instilled and nurtured and instead the constant exposure to western society has resulted in a degradation of whatever morals were created or instilled in the first place.   For others, the pressure of keeping the job and maintaining the accustomed lifestyle isolates them from other members of society in their efforts to generate more income. In India where the economic disparity was historically at lower levels, the introduction of higher paying jobs as a result of business process outsourcing has increased the rift between social and economic classes as well.   The newly emancipated and empowered women as well as the new rich employees of outsourcing firms are now experiencing things that their parents could never have enjoyed in their lifetimes such as televisions, ipods, cars and cellular phones.   The rift would not be so great however were the opportunity available equally to all sectors of society.    As it is however, only those with certain qualifications and training are allowed those opportunities and this has created a new resentment for those who have gained so much in so little time. While this has certainly generated more income for the Indian government to utilize in other social welfare projects, the income from taxes is not spent on decreasing the economic divide that exists but has actually been spent on infrastructure projects in IT designed to drum up more business and thus increasing the social gap even more.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Another reason for the widespread poverty in India lies in the failure of the government to enact programs to ensure that the economic developments that benefit certain sectors of society also trickle down to the masses.   The Indian Planning Commission has estimated that as of the year 2004 and 2005 nearly 27.5% of the Indian population was living below the poverty lines. Nearly 75% of all those living below the poverty line are located in the rural areas of India.   This shows that while most of the developed cities in India are beginning to grow, the rural areas of India are not able to benefit from this economic development.   With over 836 million citizens living on less than US$ 0.50 cents, it seems that the poverty problems of India are more rooted on the poor economic structure than anything else. Another reason for this is because of the different social, religious and economic groups that are in India.     The fact that the caste system was encouraged until the early 20th century has also added to the poverty rate in India because of the special rights and privileges that were given to others.   Coupled with the lack of property rights, since the right to property is not constitutionally declared in India, these barriers effectively prevent those from the lower economic classes of India from entering the middle class. There are a number of other reasons that can be cited as the cause for poverty in India.   Most of these theories are based on the poor economic fundamentals that were established during the British Regime and during the resulting political turmoil that resulted immediately after the transfer of power in 1947.   Be that as it may, such poor fundamentals have also given birth to other economic problems such as the growing divide between the different economic classes in India. The recent economic growth of India due to its growing role as a major player in the outsourcing industry has indeed granted a number of benefits to Indians but at the same time it has served to increase poverty in certain areas because of the failure of the government to ensure a more equitable distribution of income among the masses.   Lack of government infrastructure projects and rampant corruption remain to be the deterrents for India’s true economic growth.   Until India is able to address these problems, poverty will remain to be synonymous with the Indian Economic system for years to come.    References: Agrawal, A.

Martin Luther King’s Letter from Birmingham Jail Essay -- Martin Luthe

Martin Luther King’s â€Å"Letter from Birmingham Jail† is an excellent example of an effective argument; it was written in response to an editorial addressing the issue of Negro demonstrations and segregation in Alabama at the time. He writes in a way that makes his argument approachable; he is not attacking his opposition, which consists of eight Alabama clergymen who wrote the editorial. This is illustrated in his opening sentence: â€Å"My dear Fellow Clergymen† (464). King was an activist for civil rights during this time, and came to Alabama to help out his fellow brothers that were facing opposition. He was concerned with the monologue rather than dialogue that was going on during this time in Alabama; where each side would talk about the problem but never get together to negotiate and seek a solution. The clergymen’s editorial along with the unjust circumstances for Negroes at the time in Alabama was King’s driving force in writing this letter from his jail cell, and created an outline of a strong argument for many years to come. I have found through engaging in arguments with friends and in classes that a personal point comes across more clearly when you just present your point of view without condemning the other party. People are more likely to listen to a personal opinion or an opposing view of argument when there is no tension. Also, to the audience the argument becomes more credible when one is not attacking the opposing side. King knows that he is speaking to not only the white clergymen, but to the white moderates on a much larger scale. King addresses these moderates, saying that they are often times the most dangerous of his opposition, for at least the extremists know where they stand. He states: I have r... ... was diminished years ago? We read this because it is commonly said that â€Å"If we do not learn from history, then we are doomed to repeat it.† The racial issues are still not solved today; sexism and prejudices are evident in today’s society. King’s argument includes underlying truths that can be learned by all. Here is a man who was bold for his cause at a time that he could have, and was, killed for his beliefs; he stood up for what he thought was right, even if it was not popular at the time. Overall, King’s argument is still relevant to society and to times today, even if it is not exactly dealing with the same issues on the same level.

Effect of African Americans on World War II Essay -- segregation and di

Throughout history, many groups have been segregated at one point or another. These groups included Native Americans, Jews, and many many more. Some groups accepted their fate, while others fought to prove who they really were. Really overall, African-Americans at the time of World War II were one of the most segregated and oppressed groups of all time. However, instead of accepting their fate, they chose to prove who they were and are through fighting and other means, such as demonstrations. African-Americans helped in World War II through the 761st Tank Battalion, the Tuskegee Airmen, and other actions off the frontline. Before World War II, although Abraham Lincoln had spoken the Emancipation Proclamation in 1863 and the U.S. had gone through the Civil War around 1861, not much had significantly changed for African-Americans. Really nothing changed for African-Americans until much later, around the 1960s, when schools legally had to integrate African-Americans and whites. In relation to other events, World War II began in 1939, Jackie Robinson started on first base in 1947, and Rosa Parks was arrested in 1961. Therefore, at the time leading up to and shortly before World War II, there was not much effective action in terms of equal rights for all races. However, as seen here, after World War II, equality between races became a very prominent, pressing issue. This can partially be traced back to the effect of African-Americans in World War II. One of the first groups that come to mind when people think of African-Americans in World War II is the Tuskegee Airmen. The Tuskegee Airmen were a group of all African-American fighters who led the charge for equal rights of all races in World War II. They were the first African-Americans... ...en â€Å"Training for War â€Å"War Record This website is reliable because it is the website of a commemorative Red Tail group that honors the Tuskegee Airmen. â€Å"Women In Military Service For America Memorial.† Women In Military Service For America Memorial.

Composition and Seperations Essay

When a kernel of popcorn is heated, pressure builds and, depending on the percent of water in the kernel, the kernel pops open and popcorn is produced. The percentage of water in each kernel differs between brands of popcorn. If the steam produced fails to pop the kernel, the kernel becomes hard and burns. The purpose of Part 1, â€Å"Popcorn Composition†, of the â€Å"Composition and Separations Lab was to determine whether premium popcorn brands display desirable qualities when measured and compared with cheaper brands of popcorn. The experimental relevance of Part 1 of the experiment was to demonstrate the effects of water in a popcorn kernel when heated and converted to heat. Differences in water percentage determine whether or not the kernel will burst and create popcorn. In Part 2, â€Å"Separating a Solid Mixture†, the purpose was to work with supplies in the lab to separate a solid mixture of popcorn, sand, salt and iron filings into the four separate components to eventually learn the percent composition of the solid mixture. By developing a plan to separate the mixture, the group should have ended up with four separate items with weights that added up to the original weight of the mixture. The experimental relevance of Part 2 of the experiment was to learn how to separate each component in a four part solid mixture from each other. Procedure: In part 1 of this week’s lab three popcorn kernels of a one brand were given to each group. A Bunsen burner was set up by each group and the three kernels were each weighed separately on an electric balance. The Bunsen burner was then lit following the instructions given. (ch185) A 100mL beaker was obtained and filled with a half inch of clean sand. The beaker was placed on a ring stand and one kernel of popcorn was submerged into the sand. The beaker was then covered with a watch glass and heated over the Bunsen burner until the kernel popped. After popping, the kernel was removed and weighed and the moisture content was measured. This procedure occurred for all three kernels. After the moisture content of all three kernels were measured, an average was deduced for the three and written on the board. Each of the other four groups also wrote their averages for their individual brand on the board to give the class a better understanding of the differences in moisture content for each of the five brands. In part 2 of this week’s lab, a 50mL beaker was filled with a solid mixture consisting of popcorn, sand, salt and iron filings. The group then got the mass of the entire mixture and began sketching a plan to separate the mixture properly into its original four contents. First the group separated the popcorn from the mixture by using a drainer. The popcorn was then weighed. Second, the iron filings were separated using a magnet after pouring the remaining mixture onto a piece of paper. After the magnet collected all iron, the iron was scraped into a beaker and the weight was recorded. The third and final separation used a beaker and a filter paper. The filter paper was weighed and put into a filter that spilt into the beaker. The remaining salt/sand mixture was then poured into the filter paper using water to dissolve the salt. After the solution was put into the filter paper and the salt had dissolved, the filter paper and sand was dried and then weighed. After subtracting the filter paper weight from the weight of the filter paper and sand together, the weight of the sand was known. Once you had the weight of the sand, iron and popcorn, the weight of the salt was found by subtracting the three combined weights from the original weight of the mixture. To find the percent composition of each component, the weight of each was divided by 100 and, in the end, each components percent added up to 100% of the initial mixture. Results/ Data/ Calculations: Part 1: Each group determined the moisture percentage of their brand of popcorn. Table 1 shows the moisture content of each brand. Table 1: Moisture Percentage of Popcorn Brands Group Number| Popcorn Brand Used| Percent Moisture| 1| Act III| 6.24 %| 2| Food Club| 8.35 %| 3| Jolly Time| 12.2 %| 4| Orville Redenbacher| 7.47 %| 5| Pop Perfect| 6.22 %| Jolly Time popcorn was measured for weight and the moisture content was then measured. Table 2 shows the initial weights, final weights, moisture contents and percent moistures of each of the three trials performed. Table 2: Moisture Percentage by Weight of Jolly Time Popcorn Kernels Kernel| Initial Weight (g)| Final Weight (g)| Moisture Content| % Moisture| 1| 0.105 g| 0.086 g| 0.019 g| 17.8 %| 2| 0.138 g| 0.140 g| -0.003 g| -1.89 %| 3| 0.113 g| 0.106 g| 0.007 g| 6.55 %| AVERAGE| 0.109 g| 0.096 g| 0.013 g| 12.2 %| Sample Calculations: Find weight= (cupcake holder + kernel – cupcake holder) = (.263 g – .177 g) = 0.086 g Moisture Content= Initial weight – final weight = 0.105 g – 0.086 g = 0.019 g % Moisture= Moisture content x 100 Initial weight of kernel = 0.019 g = 17.8% 0.105 g Average % moisture = 17.8 + 6.55 = 12.2% 2 Part 2: The weight and eventually percentage composition was measure in a mixture of corn, iron, sand and salt and then with each component individually. Table 3 shows the weight and % compositions. Table 3: Percent composition of Mixture Material| Weight (g)| % Composition| Full Mix| 42.2 g| 100 %| Corn| 3.26 g| 7.79 %| Iron| 19.0 g| 45.0 %| Sand| 15.7 g| 32.5 %| Salt| 6.25 g| 14.8 %| Sample Calculations: Percent Composition:Initial Weight x100 Total Mixture Weight Beaker with nothing: 59. 95 g Beaker with mix: 102.1 g W/ Mix:102.1 g W/O Mix: – 59.95g 42.98 g Discussion: The experiment in part 1 was done to show that even slight differences in moisture content in popcorn make a big difference when it comes to the popcorn’s â€Å"popping† abilities. Before the experiment, the moisture content and its effect on popcorn were unknown. After the experiment each group left with the knowledge of moisture content in both preferred brands and cheap brands of popcorn. This experiment gave insight into the importance of exactness for popcorn companies pertaining to the moisture content in each kernel. The experiment in part 2 was performed to show that most solid mixtures can be separated if using the right tools. Each group had to propose a solution to separating the mixture and then weighing each of the four components afterwards to conclude if they added up to the initial weight of the solid mixture. This experiment allowed students to use their brains to separate any solid mixture that they come in contact with, which will be helpful for the future in this lab and others. Throughout the two parts of this experiment several specific errors were found and dealt with. In part 1 of this experiment several popcorn kernels were burnt and did not pop. These kernels may have affected our experiment by giving us false data, as we did not include these kernels in any final data. With burnt popcorn kernels, we were shown that the moisture content in the popcorn brand given may have resulted in one of the â€Å"cheap† brands given. In part 2 of our experiment, the initial weight was supposed to be taken before separating any part of the mixture. Unfortunately, the initial weight was skipped before the popcorn was separated. The popcorn then had to be put back into the mixture and the mixture was then weighed for the initial weight. This may have affected the final data, although it was a small error. In part 2 another error occurred when the group began to separate the salt and sand in an incorrect manner. This, however, did not affect final data, as the salt would have been eliminated anyway. Conclusions: The goals in this experiment for part 1 were to determine the moisture content in a brand of popcorn, compare the given brand with others in the lab and then find out if moisture content affects the ‘popping’ or corn and which brand or brands has a better likelihood of popping (i.e. preferred vs. cheap brands). In part 2 of the experiment the goals were to separate a solid mixture and then find the percent composition of each of the four materials within the mixture. The average moisture percentage for Jolly Time popcorn was 12.2 %. To get to this point, the group popped three separate kernels and found the moisture percentage for each and then averaged them. The percent composition for part 2 of the solid mixture was 7.79 % for corn, 45.0 % for iron, 32.5 % for sand and 14.8% for salt. These measurements added up to the 100% solid mixture and the weights added up correctly. References: Ch185.

Well regulated militia

A Well regulated militia, being necessary to the security of a free State, the right of the people to keep and bear arms , shall not be infringed. Amendment II, Bill of Rights Constitution of the U.S. The Second Amendment has been a major issue in American politics since 1876. In question is the intent of this Amendment. Was it meant to insure that people in general have arms for personal service, or was it intended to insure arms for military service? The nation's powerful gun lobby, the National Rifle Association, holds that it means the right to keep and bear arms -any arms. This privileged right is given to those 60-65 million people who choose to own guns. The NRA also believes that human character defects cannot be changed by a simple regulation of guns. They argue that problems with firearm ownership cannot be, in any way, associated with criminal violence. The lobbyist give credibility to this statement by adding that criminal violence continues to increase in cities like New York and Washington DC, even though gun control statutes were put into affect. They point out that gun laws would not have stopped most addicted killers. According to the NRA, anti-crime measures are the way to conquer urban violence, not anti-gun measures. The hope of most members in the association is to educate people about guns. The association is willing to reveal proper usage of guns to non-gun owners. They feel that this training could help reduce some of the tragedies involving guns. The issue of gun control has become a dividing line in America. To gun control activists, the issue is about crime and the regulation of the weapons used to commit these crimes. In their opinion, law abiding citizens should have no need for guns. In this respect, the big controversy seems shallow . However, to t...
