Look at the the instruction (2) - Essay Example In solution, ethanol reacts with the potassium dichromate, reducing the dichromate ion to chromium(III) ion. This reduction results in a change of the solution’s color from red orange to green. The extent of the color change, precisely measured by photoelectric cells revealed the amount of alcohol in the sample (Willet, 1996). This chemical analysis though, is not very accurate due to the presence of interfering compounds which are similar in structure with alcohol. Since potassium dichromate is a strong oxidizer, numerous alcohol groups can be oxidized by it, thereby producing false positive results. New models include breathe analyzers using the fuel cell and infrared technologies. In a fuel cell, two electrodes are immersed in an electrolyte – a substance that conducts electricity. Fuel, typically hydrogen, is provided to one electrode, and oxygen to the other. The result is a flow of electricity between the electrodes . In a breathe analyzer, the alcohol in the breathe becomes the fuel for the fuel cell, the higher the concentration of alcohol in the breathe, the more electricity is generated. The measure of the strength of the current being generated will determine the concentration of alcohol in the breathe sample (Willet, 1996). The fuel cell technology may be considered as chemical sensor even if it is the electricity generated that is being measured. The electricity generated is proportional to the amount of fuel supplied by the alcohol group to the fuel cell. This means that the electricity generated is dependent on the fuel or the amount of alcohol supplied. The limiting factor or the sensor is the alcohol compound in the breathe sample. When the alcohol in the breathe sample is already exhausted, generation of electricity will also stop. Thus, the alcohol from the breathe sample is considered as the chemical sensor since the electricity generated is

Intellectual History Term Paper Example | Topics and Well Written Essays - 2250 words - 1

Intellectual History - Term Paper Example Peter Warren discovered remains of children dating back to 2000 B.C. The buildings found during Warren’s expedition encountered a massive earth quake. According to Warren, the remains were of the children who were sacrificed, in order to prevent the anticipated earth quake. Sacrifice is one of the most striking concepts existing in the history of humankind; animals, humans and sometimes even gods were sacrificed in human history. Human sacrifice is still practiced by many civilizations. In accordance with Hinduism, the wife has to sacrifice herself and burn with her husband in order to stay with her husband after his death. In Mexico, children were sacrificed to be blessed with plentiful rains for the harvest. Sacrifice is primarily deemed as a link between the divine/spiritual and subordinate humans. It customarily has aspirations like doing away with the wrath of gods and altering the behavior of gods in favor of people offering the sacrifice (The Watson, 134-135). Like the era of the bulls and sacred stones; in India, Indra the goddess was compared to the bull. Bulls were sacrificed in the ancient civilization of Iran. In North and South America, parts of lands in Pacific Ocean and Mexico, a young girl was beheaded every time a crop was ripe.   Early variant of sacrifices did not involve any kind of animals; in fact the animals were worshiped. Self denial is also an important factor that is entailed in making a sacrifice. Denial of self for the benefit of others and in the way of gods is significantly increasing even in today's times, in order to maintain balance between human and spiritual world. Ancient civilizations like ancient Egypt, Sumer and India followed the philosophy of sacrifice. Another fundamental concept in faith of people, is belief in sky-gods; the concept of sky-gods. Movement of sun and its relation with change of climate, changing over day into night (referred to as birth and re-birth of sun) was a mystery for humans. Likewise, t he moon cycle; its appearance and disappearance and connection to tides in sea and female menstrual cycle made it more mysterious for the humans. The Indian god Dyaus, Roman Jupiter and Greek Zeus all came from a single concept pertaining to sky divinity. Sun god was considered a symbol of males and moon gods being a female symbol. Sun god was also worshiped by ancient believers of Egyptian religion. The concept leads to another idea that exists in humans known as â€Å"afterlife†. Generally after life means existence after the physical death of the body. In ancient Egyptian religion, bodies were buried along with food, water and other necessities; adopting the concept that after burial, body will be alive again. As sun and moon appear and disappear; In the same way some sort of post-mortem existed in the minds of people. This leads to another mysterious concept known as â€Å"Soul†.   According to peoples soul is contained in different parts of the body such as eyes , ears, stomach, and above all the heart. Hindus believe that soul is thumb sized and it resides in the heart. Greeks perceived soul as light or fire of the heart. Ancient Egyptians believed that there were two other beings present in addition to body itself, called â€Å"Ka† and â€Å"Ba†. â€Å"Ba†, in medieval Egyptian religion was deemed a soul mirrored by a human headed bird. â€Å"Ka† was the protector of body. Death can manifest only if it had permission from â€Å"

Sowftware design problem Research Paper Example | Topics and Well Written Essays - 1000 words

Sowftware design problem - Research Paper Example The power of computers in such an activity leads to the establishment of numerous software companies, which are engaged in developing a variety of applications. As a safety related system is under development, a safety argument is under preparation that shows why confidence needs to be put in the system’s ability to meet safety requirements. This leads to the question why those requirements demand safe operation. The moment the system and its arguments are acknowledged, the system is set into operation. Faults may still exist in the system or in its maintenance or operational procedures if the safety argument is not complete. If triggered, the faults can lead to a failure. In such a case, an analysis needs to be conducted to distinguish the nature of the failure. It might be random or even systemic, i.e. due to a design fault, which was introduced when the system was being developed or serviced. Failures that arise from systemic faults must be comprehensively analyzed to avoid recurrences (Baah 3). Large projects, for example, Agropoli’s system of public transportation involves qualified personnel in the software development process. Software companies face several issues in the process of software development. These include: possible negligence of the software developer and another involves possible negligence, but adds another party who happens to be the malicious hacker. Other problems include change of rules during development, preservation of existing software, flexibility due to lack of standards as well as behavior of discrete systems. The complexity involved in the process of software development leads to software bugs. Late completion, low quality, lack of reliability and software not satisfying the stated demand are the symptoms of software bugs. In a scenario, for example, the Agropoli’s system of public transportation where the system under development is discovered to have some difficulties during

Analysis + Memo. Playa Dorada Case Study Example | Topics and Well Written Essays - 1250 words

Analysis + Memo. Playa Dorada - Case Study Example I hope that I will be able to highlight the potential feasibility, profitability and suitability of the proposed expansion, in such a way that enhances our investment returns. Welcome. Background To begin with, you are aware that the Playa Doranda Beach & Resort in Florida has been doing very well in setting up a residential center alongside highly esteemed hotels. The residents and guests in these two units are expected to reach maximal capacity soon, thus increasing the number of people using our facilities. Further, the usage of tennis facilities has been on the increase and is likely to push us above our current capacity in the next few months. Based on vocation and tourist arrivals, there is a likelihood that our tennis facilitates will soon be inadequate. Our marketers and strategic business planners have already guaranteed increased growth of tennis demand in the location. Considering that our 18-hole golf course and Olympic sized swimming pool were also essential future inves tments that are now legendary in returns, it is strategically logical to conclude that we now need to extend our tennis infrastructure. Between 2004 and 2007, our court usage increased from 18.4% (by 2,789) players, to reach 47.3% (by 32,816 players). This was a nearly 30% increase of tennis court usage within three years. This rate or growth predicts when our tennis facilities as they are now, will be inadequate. With that kind of growth rate, our tennis courts face maximal over use in less than five years from 2007. Proposal My proposal for the next financial year is to amend the current pricing structure, and make it more competitive. Our tennis facilitates are impeccable in quality and the best in these regions. As such, since we have and we will sustain a maximal demand among players and visitors, we can optimize our profitability by increasing our prices, and being more expensive in our tennis programs. Further, even with increased prices, our tennis facilities are likely to r egister extreme numbers of potential players, as we are now, if not more when occupation increases. As such, I propose that we need to increase our tennis facilities and infrastructure, by building new courts and extending those that are currently operational. This will continue to optimize our revenue generation, not only because of new facilities, but also with the increased pricing structure. It is a highly expensive investment proposal, but the potential optimal returns are as gigantic. Conclusion Building a hotel and residential infrastructure have been central to tradition, our history and the consequent success as was demonstrated by our lucrative villa sales a few years ago. In this understanding, investing in better facilities and preparing our company with an essential expansion of our tennis club is essential. That is my proposal, hoping to maximize on the future returns on our investment, within a market that is most likely going to grow extremely huge in the near future . Thank you. SWOT Analysis The SWOT matrix can be used to analyze the potential benefits of the proposed expansion. SWOT helps profile the Strengths, Weaknesses, Opportunities and Threats of a business proposal. This will help justify the essence of the proposal, based on strategic analysis of future market of tennis courts and tennis facilities. As such, the following is a brief SWOT analysis of the proposal: A) Strengths (Potential returns for the business proposal over possible alternatives). The expansion proposes the construction

Applying International Trade Concepts simulation and economics Research Paper

Applying International Trade Concepts simulation and economics - Research Paper Example Consequently, parties to an international trade require a globalized perspective and an approach that can manage the complex regulatory environment of international trade. The diversity challenge also extends to culture that require cultural sensitivity, cultural awareness, and collaborative measures for effectiveness. These issues are however absent or are less significant in domestic trade environments. International trade regulations also form another issue in the trade because of required compliance. Parties must therefore have knowledge diverse regulatory frameworks (Selivanova, 2011). Economic environment is another significant issue that surrounds international trade. Factors such as an economy’s gross domestic product, â€Å"inflation, per capita income, and disposable income† are significant to viability of a business in an economy and in comparative analysis to determine the best economy to conduct business in or with which to conduct business (Singh, 2009, p. 43). Political environment is another issue affecting international trade, includes factors such as stability and perception towards foreigners, and determines a country’s level of attractiveness to investors. Availability of technology and of resources is another issue surrounding international trade. A party to international trade will therefore consider these factors before making a decision to venture into international trade and on which location to

Planning in the Roman Empire Essay Example | Topics and Well Written Essays - 750 words

Planning in the Roman Empire - Essay Example The emperor also provided a lot of economic opportunities that people could take advantage of. The emporium faced major problems in maintaining security and peace and in governance. The central government also had devolved a lot of its governance responsibility of local affairs and certain imperial duties to the cities. There was a lot of competition within between the cities in the empire. The competition is evident bearing in mind how the senior citizens competitively vie with each other for recognition by the public and for senior civil posts. Cities also competed with each other to gain honorific titles. However, the competition of the cities was to some extent beneficial to the empire as it fostered decorative and architectural developments as they strove to outdo rival cities in the â€Å"splendor of their public monuments and the variety or their urban facilities†(p122). The competitions also brought other potential dangers. Some building projects which were undertaken in cities like Bithynia were left unfinished. Much of the empire’s resources were concentrated on development. New ideas, techniques, buildings and materials for building were employed in a bid to come up with bigger more impressive buildings. More architectural work was done. The focus of the empire was on transforming the existing cities and fostering growth of cities in the urbanized provinces. Civic planning can achieve various benefits if well done and implemented. On the other hand, if not well planned or implemented, it can end up having a lot of negative results. In the empire, buildings would give a sense of solidarity which was not the situation on the ground as the cities were strong competitors. The buildings were magnificent and beautiful which would also have given a sense of unity in the empire, which was not also the case. Many buildings also had been started

Opposition to Immigration Essay Example | Topics and Well Written Essays - 1250 words

Opposition to Immigration - Essay Example In a strict economic sense 2006 has been a good year till now. As a matter of fact, even from 2004, the economy has been looking up. Economic growth which was 4.2 % in 2004, was 3.5% in 2005; which is still good. Unemployment at 4.7% is quite an achievement compared to the 8.4% figure for Europe. However it looks as if it will take more than that to whistle a happy tune. ("The United States ...") The steadily increasing trade deficit, Katrina, the involvement in Afghanistan and Iraq, our standoff with Iran, and the regular outflow of jobs through outsourcing are enough to dampen the spirit of the average American. Add 12 million illegal immigrants. And a pall of gloom descends over middle class America. Fact is many Americans are seriously concerned about the immigration issue. It has become a subject that has dominated a variety of forums and has spawned several localized movements. One such local unit that called itself "Minutemen" patrolled Arizona's border with Mexico during April 2005. This anti-immigration sentiment is sometimes referred to as "nativism". ("Immigration Policy Issues") "Nativism" is not new to America. It first reared its head at the beginning of the 19th century when hordes of immigrants from Southern and Eastern Europe began to pour in. The consequence of that nativist stirring was "a 1924 law establishing a quota system that sought to limit entry" into the United States. (Campo-Flores) The more recent immigration issues however relate primarily to illegal immigrants, and the conviction in some quarters, that the huge inflow of these "undocumented" workers is the cause for the country's woes. In the 1980s the American people were highly unsatisfied with the Federal policies of the 1970s and early 1980s. In 1982 the country was in a deep recession. The percent of businesses that went bankrupt increased by 50% when compared to the previous year, agricultural exports fell, as did the price of crops. Interest rates rose, inflation was up from 6.2% in 1973 to around 13.5% and unemployment was at a significant high of 7%. (Teacher's Guide). Federal deficits soared throughout this period. This was probably the worst period in America's economic history since the Depression of 1929. During the period 1980 to 1990 Immigration and Naturalization Service (INS) estimated the number of illegal immigrants to be around 2.6 million. The general sentiment then was that 3 these undocumented immigrants were the cause of all economic woes. As a consequence we had the Immigration Reform and Control Act (IRCA) of 1986. The primary aim of this Act was to protect the jobs of the domestic workforce. It also sought to punish employers of undocumented workers. (The Feminization of Immigration) The immigration issue is currently seen as a bigger problem than it was ever before. It's not surprising. For instance, Gordon County, Georgia had an immigrant population of just 1% in 1990. Today that figure stands at 12%. According to the Pew Hispanic Center, illegal immigrants currently make up 24% of agricultural labor, 14% of construction workers and 9% of manufacturing jobs. (Grow) The Bill that was passed by the House last December,
