Are people becoming too dependant on computers In a well-developed , argue for or against people being too dependent - Essay Example Nevertheless, with the entry of the internet in the market, people have access to information, an aspect that makes them not to strive while looking for long-lasting solutions. This has reduced the level of innovation especially among the young people. Computers have brought a lot of changes, some of which have negative impact on the users. Initially, cases of obesity were very rare. People used to perform physical work which made them to remain fit. However, in the modern world, many things have been computerized. For instance, the transport system is more effective thanks to computers. Therefore, less people are opting to walk even for short distances (Jacko and Andrew 37). This aspect is having a major impact on the health of the people. Statistics indicate that the number of people suffering from chronic diseases that result from less exercise is increasing tremendously. If the trend is not arrested, the situation is likely to worsen each day. Initially, people used to interact and share ideas and concerns. The family members used to meet and discuss on issues that affected their relationship. However, overreliance on computers and computer-enabled technologies has affected the relationship between people. This is because computers users have been unable to control the time they spend on computers. This has even been accelerated with the entry of the internet. Initially, children used to spend their time playing with their friends. This enabled them to develop physically and psychologically. However, currently, they are spending much of their time chatting with friends or playing computer games. This is having a major effect on their health. Introduction of personal computers has increased people’s reliance on these devices. People are no longer willing to use the traditional means to get information. This has led to emergence of online courses, libraries, and other important resources. Although this breakthrough has made life easier for the

ATM network Essay Example | Topics and Well Written Essays - 250 words

ATM network - Essay Example Another problem is that whenever there is a communication error during transmission, a package of data being transmitted can easily be corrupted (William 36). This would force a retransmission of the whole package. These incidences can be reduced through data fragmentation Taking ‘n’ to be the number of cells required to transmit a single IP datagram, we can form an expression of the cell loss rate in the ATM network (PC) as the ratio of nc (number of cells corrupted) to n (the number of cells required to transmit a single IP datagram). The IP-packet loss rate (PP), would therefore be the ratio of corrupted packets to all received packets. The IP-packet loss rate depends heavily on the success of the transmitted packets, and this in-turn depends on the number of cells that are successfully transmitted. In order to receive the best perfomance of data transmission, it is good to tune the Maximum Transmission Unit. This service is made possible by some Information Technology providers through using ATM on their internal backbone network. This ensures that the right amount of sustainable data is transmitted and reduces fragmentation of

The Study Of Solubility Equilibrium

The Study Of Solubility Equilibrium The first part of this experiment aims to determine the solubility product constant of potassium hydrogen tartrate in water, and thereby determine how the enthalpy and entropy change of the dissolution reaction, according to the equilibrium KHC4H4O6 (s) Ġº K+ (aq) + HC4H4O6- (aq) (1), changes with temperature. The second part of this experiment aims to examine the common ion effect through determination of the Ksp of KHC4H4O6 in potassium nitrate (KNO3) solution for varying K+ concentrations. Results I. Titrating 25.0cm3 of KHC4H4O6 solution with 0.07415M NaOH solution with phenolphthalein indicator gave the following results To determine Ksp at 302.15K: Amount of NaOH used = Average volume of NaOH used 0.07415M = 13.35 10-3 0.07415 = 9.899 10-4 mol = Amount of HC4H4O6- reacted Total volume of the solution = Average volume of NaOH used + 25.0 cm3 of HC4H4O6- solution = 13.35 + 25.0 = 38.35 cm3 Since [K+] = [HC4H4O6-], Ksp = [K+][HC4H4O6-] = [HC4H4O6-]2 = 0.25812 = 6.662-10-4 Table 1: Solubility product constant of potassium hydrogen tartrate at various temperatures Temperature / K Average VNaOH used / cm3 Amount of NaOH used / mol Amount of HC4H4O6- reacted / mol [HC4H4O6-] / mol dm-3 Solubility of HC4H4O6-/ mol dm-3 Ksp ln Ksp 1/T / K-1 282.5 6.65 0.0004931 0.004931 0.01558 0.01558 0.0002427 -8.324 0.003540 292 9.25 0.0006869 0.006869 0.02003 0.02003 0.0004010 -7.821 0.003425 302 13.35 0.0009899 0.009899 0.02581 0.02581 0.0006663 -7.314 0.003311 311.5 18.35 0.001361 0.01361 0.03139 0.03139 0.0009852 -6.923 0.003210 322.5 26.65 0.001976 0.01976 0.03826 0.03826 0.001464 -6.527 0.003101 Given that ΔG °reaction = ΔH °reaction TΔS °reaction - (2) and ΔG °reaction = RT ln K - (3), combining the two equations and rearranging gives us the linear function: - (4) Using the data obtained in this experiment to plot this linear function gives Graph 1 shown below: Graph 1: Linear curve of ln Ksp against 1/T Equation of line -ln Ksp = 4113(1/T) + 6.264 =- 4113 ΔH °reaction =- (- 4113 8.314) =+34 195 J mol-1 (4s.f.) =+34.195 kJ mol-1 Uncertainty (standard deviation) =  ± 105.3 8.314 =  ± 875.5 ΔH °reaction = + 34 195  ± 875.5 J mol-1 =6.264 ΔS °reaction =6.264 8.314 =+52.08 J K-1 mol-1 (4s.f.)

Since the magnitude of ΔS °r is smaller than that of ΔH °r, ΔG °r is always positive in the temperature range of 282.5K to 322.5K, as carried out in this experiment. This indicates that the dissolution of KHC4H4O6 is always non-spontaneous for this temperature range, and hence KHC4H4O6 is a sparingly soluble salt. II. Titration of KHC4H4O6 in KNO3 solutions of different concentrations with 0.07413M NaOH solution with phenolphthalein indicator at room temperature to observe the common ion effect gave the following results To determine the Ksp and solubility of HC4H4O6- at room temperature when [KNO3] = 0.01M: Amount of K+ from KNO3 = 0.01 70 10-3 = 7.00-10-4 mol Amount of NaOH used = 11.45 10-3 0.07413 = 8.508 10-4 mol = Amount of HC4H4O6- reacted Total amount of K+ = (7.00-10-4) + (8.508 10-4) = 1.55 10-3 mol Total volume = 25.0 + 11.45 = 36.45 cm3 [K+]total = Ksp = Table 2: Solubility product constant of potassium hydrogen tartrate at various potassium nitrate concentrations T / K [KNO3] / M Average volume of NaOH used / cm3 Amount of NaOH / mol Amount of HC4H4O6- reacted / mol Total amount of K+ / mol [K+]total / mol dm-3 Solubility of HC4H4O6- / mol dm-3 Ksp 301 0.01 11.45 0.0008509 0.0008509 0.001551 0.04255 0.02334 0.0009932 301 0.02 10.35 0.0007691 0.0007691 0.002169 0.06136 0.02176 0.001335 302 0.03 9.50 0.0007059 0.0007059 0.002806 0.08133 0.02046 0.001664 302 0.04 8.60 0.0006391 0.0006391 0.003439 0.1024 0.01902 0.001947 Graph 2: Graph of solubility of KHC4H4O6 (M) against [K+]total (M) The data obtained in this part of the experiment shows that solubility of HC4H4O6- decreases with increasing total K+ concentration for a given temperature (302K). This is due to the common ion effect the presence of the common ion K+ suppresses the dissociation of KHC4H4O6 according to (1), since K+ concentration is greater than the equilibrium KHC4H4O6 concentration. The greater the K+ concentration, the lesser the extent of dissociation of KHC4H4O6, and hence the less soluble HC4H4O6- is in water. Discussion The solubility of a substance is the amount of the substance dissolved in 1 L of its saturated solution for a given temperature. Ksp on the other hand, is the product of the ion concentrations raised to their respective powers on the dissolution equilibrium equation, and is constant for a given temperature. Since the dissolution of KHC4H4O6 is an endothermic process, when temperature increases, the forward reaction is favoured to absorb the excess heat. This causes Ksp values to increase with increasing temperature, as observed, since concentration of products, i.e. [K+] and [HC4H4O6-], increases. The heat absorbed is used to overcome solute-solute and solvent-solvent interactions, such that solute-solvent interactions can form during the dissolution process. Also, as a solid dissolves, entropy of the system is increased, since the greater number of liquid particles increases disorderliness. Hence as temperature increases, ΔG °r will be increasingly negative, indicating that the dissolution of KHC4H4O6 gets increasingly spontaneous as temperature increases. In this experiment, ΔH °r and ΔS °r are assumed to be insignificantly dependent on temperature. ΔrH(T2) = ΔrH(T1) + (T2-T1) ΔrCp - (5) (Atkins, 2006) From Kirchhoffs law (5), ΔrH is dependent on temperature, assuming that constant-pressure heat capacities (Cp) is independent of temperature. For the above assumption to hold true, ΔrCp should be insignificant, i.e. (Cp) of the products and reactants should have approximately equal values. Since Cp is affected by how much of a substance there is in the solution the greater the number of particles, the greater the amount of heat energy needed to raise the overall temperature of the solution by 1K and the KHC4H4O6 solution used in titration is saturated, the amount of substance in the solution can be approximated to be the same. Thus, Cp of the products and reactants can be approximated to be the same, and hence ΔrCp is minimum. Similarly, since ΔS °r is dependent on Cp as well, we can assume it to be insignificantly dependent on temperature as well. For the above argument to hold true, the KHC4H4O6 solution used in titration must be saturated, and steps to ensure this should be taken one, continual swirling of the solution before filtration to ensure all solid has been dissolved; two, maintaining supposed temperature of the solution immediately before filtering, since the saturated solution is filtered in small portions; three, apparatus used to contain the filtrate must be dry such that the saturated solution is not diluted by the presence of any water. General titration techniques were also employed, such as rinsing apparatus with the solutions that they are to contain to ensure no contamination and accurate concentrations, as well as keeping the amount of phenolphthalein indicator, a weak acid, to a minimum, to prevent the lowering of the pH of the solution, which results in more than the required amount of NaOH needed to react with the saturated KHC4H4O6 solution. For Section 1 of this experiment, comparing experimental and literature Ksp values gives the following At approximately 302K: Literature value of solubility of KHC4H4O6 in water = 7.3693 103 kgsalt/kgwater (Lopes, 2001) Literature Ksp value = [(7.3693 103 gsalt/mlwater) à · (188.1772 g mol-1)]2 = (39.161 10-3 mol L-1)2 = 1.534 10-3 Experimental Ksp value (Section 1) = 6.663 10-4 Mean Ksp value (Section 2) = 1.485 10-3 The literature Ksp value in Section 1 of this experiment was 2.302 times higher than that of the experimental Ksp value at 302K. Besides, since Ksp is only dependent on temperature, Ksp values at the same temperature should be constant and independent of concentrations. The mean Ksp value obtained in the Section 2 of this experiment, however, was 2.229 times greater than that obtained in Section 1 of this experiment, though it only had a 3.300% difference from the literature Ksp value. The abnormally low Ksp value obtained in Section 1 of this experiment indicates less than expected K+ and HC4H4O6- concentrations in the solution, and can stem from either the effect of a deviation from temperature, or from the solution being unsaturated. However, the data obtained in this experiment showed an accurate trend expected of Ksp values for increasing temperature, hence eliminating temperature deviation as a possible source of error. Furthermore, this trend also reflects expected solubility trends, and is sufficient in demonstrating the aims of this experiment. Conclusion The aims of this experiment have been met, as shown by the increasing trend of Ksp values for increasing temperature, as well as the decreasing solubility of HC4H4O6- in water for increasing K+ concentration, due to the common ion effect. These combined prove that Ksp is only dependent on temperature, given that care has been taken to ensure a saturated solution when carrying out the experiment.

aldous huxley :: essays research papers

Aldous Huxley was born in Surrey, England on July 26, 1894 to an illustrious family deeply rooted in England's literary and scientific tradition. Huxley's father, Leonard Huxley, was the son of Thomas Henry Huxley, a well-known biologist who gained the nickname "Darwin's bulldog" for championing Charles Darwin's evolutionary ideas. His mother, Julia Arnold, was related to the important nineteenth-century poet and essayist Matthew Arnold. Raised in this family of scientists, writers, and teachers (his father was a writer and teacher, and his mother a schoolmistress), Huxley received an excellent education, first at home, then at Eton, providing him with access to numerous fields of knowledge. Huxley was an avid student, and during his lifetime he was renowned as a generalist, an intellectual who had mastered the use of the English language but was also informed about cutting-edge developments in science and other fields. Although much of his scientific understanding was superficial—he was easily convinced of findings that remained somewhat on the fringe of mainstream science—his education at the intersection of science and literature allowed him to integrate current scientific findings into his novels and essays in a way that few other writers of his time were able to do. Aside from his education, another major influence on Huxley's life and writing was an eye disease contracted in his teenage years that left him almost blind. As a teenager Huxley had dreamed about becoming a doctor, but the degeneration of his eyesight prevented him from pursuing his chosen career. It also severely restricted the activities he could pursue. Because of his near blindness, he depended heavily on his first wife, Maria, to take care of him. Blindness and vision are motifs that permeate much of Huxley's writing. After graduating from Oxford in 1916, Huxley began to make a name for himself writing satirical pieces about the British upper class. Though these writings were skillful and gained Huxley an audience and literary name, they were generally considered to offer little depth beyond their lightweight criticisms of social manners. Huxley continued to write prolifically, working as an essayist and journalist, and publishing four volumes of poetry before beginning to work on novels. Without giving up his other writing, beginning in 1921, Huxley produced a series of novels at an astonishing rate: Crome Yellow was published in 1921, followed by Antic Hay in 1923, Those Barren Leaves in 1925, and Point Counter Point in 1928.

Marie Ziegler of John Deere Essay

The characteristics of effective sustainable business leadership consist of having a vision of what the business is aiming to attain, seeing the value in the process and providing the leadership to attain the goal. The leadership starts with believing in yourself knowing that your capable of making your dreams come true. John Deere was born on February 7,1804 in Rutland, Vermont. In 1836 John Deere moved to Grand Detour, Illinois to escape from depressing business conditions he had in Vermont. Capable and hard working John Deere used his skills as a blacksmith were instantly in command. John Deere opened his shop in 1837 allowing him to operate as a general repairman as well as a manufacturer of small tools such as pitchforks and shovels. Using a broken saw blade Deere created a plow in the year of 1837. By 1841, Deere produced 100 plows annually. Two years later became an alliance with Leonard Andrus to fabricate more plows to increase demand purchasing a new land for the building of a new two-story factory alongside of the Rock River in Illinois. This factory produced about 400 plows in that same year. Regardless the success, Deere’s alliance with Andrus finished in 1848, when Deere moved to Moline, Illinois which offered advantages of water power, coal and cheaper transportation than to be found in Grand Detour. In 1850, approximately 1600 plows were made, and the company was soon producing other tools to complement its steel plow. In 1858, Deere transferred leadership of the company to his son, Charles, who served as its vice president. John Deere retained the title of president of the company, but now turned his attention to civic and political activities. John Deere was active in public life throughout his career in Moline. Among other roles, he was a founder and president of the National Bank of Moline, was an active member of the First Congregational Church, and served as the city’s mayor for two years. John Deere died on May 17, 1886, at his home in Moline. (â€Å"Past Leaders â€Å", 2014). After the death of John Deere the company was producing a collection of farm tools in addition to plows, plus wagons, corn planters, and cultivators. At the same time the company expanded into the bicycle business during the 1890’s, but the essential focus stayed on agricultural imp lements. Increased  competition during the early 1900s from the new International Harvester Company led the company to expand its offerings in the implement business, but it was the production of gasoline tractors which would come to define Deere & Company’s operations during the twentieth century. After Charles Deere death in 1907, William Butterworth Deere & Company new president started the business expansion into the tractor business. During the years John Deere has been increasing profits as well as production becoming one of the best equipments for farming. According to â€Å"Past Leaders † (2014), (Deere & Company (NYSE: DE) is a world leader in providing advanced products and services and is committed to the success of customers whose work is linked to the land – those who cultivate, harvest, transform, enrich and build upon the land to meet the world’s dramatically increasing need for food, fuel, shelter and infrastructure. Since 1837, John Deere has delivered innovative products of superior quality, built on a tradition of integrity). As of 2014, Deere & Company employs approximately 67,000 people in 27 countries worldwide, including the United States, Australia, Turkey, Canada, United Kingdom, China, France, Germany, Spain, Italy, India, Poland, Mexico, Argentina, Brazil, Morocco and South Africa, among many others and is the greatest agriculture machinery company in the world. Inside the United States, the company’s primary locations are its administrative center in Moline, Illinois and manufacturing factories in central and southeastern United States. (â€Å"John Deere†, 2014). Marie Z. Ziegler is Vice President and Treasurer for Deere & Company, a position she’s held since November 2010. Ziegler is responsible for the company’s worldwide treasury and investor relations activities. Ziegler joined Deere & Company in 1978 as a consolidation accountant and has held management positions in finance, treasury operations, strategic planning and investor and banking relations. She served as Director of Investor Relations, and in May 2001, was appointed Vice President, Investor Relations for Deere & Company. (â€Å"John Deere†, 2014). The John Deere portfolio of businesses is varied, yet interrelated. Two of our businesses – Agricultural and Construction equipment – are in an excellent position to take advantage of global growth. Two additional  businesses – Turf and Forestry equipment – support and enhance worldwide channel development. And additional supporting businesses – Financial Services, Power Systems, Parts Services, and the Intelligent Solutions Group – strengthen and differentiate our equipment businesses. Strategy. (2014). The key for John Deere success is having exceptional operating performance, disciplined SVA growth, and aligned high-performance teamwork. These factors direct success for this company as they are important for the future of John Deere as they leverage and create core strengths.. John Deere future successes will require more people working for them. For that reason, they are creating strength in four additional capabilities: Deep Customer Understanding, Delivering Customer Value, World-class Distribution System, and Growing Extraordinary Global Talent. These additional success factors are critical in order to achieve sustainable SVA growth through global growth. Shareholder Value Added (SVA) – the difference between operating profit and pretax cost of capital – is a metric used by John Deere to evaluate business results and measure sustainable performance.

ESSAY |Assessment question |By using corporate social responsibility (CSR) the tobacco industry is seeking to change their unethical public | | |image. Evaluate this strategy using three ethical principles of the Global Business Standards Codex. | Type your essay below:The tobacco industry has come under scrutiny regarding their us e of corporate responsibility to change an unethical image that has plagued them since the latter half of the 20th century. The purpose of this essay is to evaluate the use of corporate social responsibility using three ethical principles of the global business standards codex and studies reviewing the tobacco industry’s use of corporate social responsibility in relation to the health issues, environmental issues and the social issues concerning the tobacco companies. The tobacco industry’s use of corporate responsibility to change their unethical public image is ineffective and disingenuous, as they are simply using this strategy as a defence against public disparagement.The farming and production of tobacco carries widespread environmental impacts which are damaging to the surrounding ecosystems and natural processes. British American Tobacco and Phillip Morris had established supply chains in the 1990s as a means of farming tobacco more efficiently aiming to maximis e profits (Otanez & Glantz 2010). However these supply chains were damaging to the environment as well as local communities of developing countries as deforestation and the use of child labour on tobacco plantations became widespread throughout these supply chains. In the 2000s these companies addressed the environmental and labour concerns by redefining their tobacco farming procedures and implementing environmentally sustainable practices.Although it was revealed through the studies undertaken by Otanez & Glantz (2010) that the tobacco farming practices remained the same and this attempt to deceive the public was revealed to be a CSR exploit. The use of corporate social responsibility seeks to minimise risks and adverse effects maximising economic and social benefits establishing relationships based on trust to promote progress in accordance with ethical principles and moral values (Crisan, CM & Borza 2012). In terms of the Business Standards Codex, the tobacco industry violates t he citizenship principle which states that â€Å"Every employee should act as a responsible citizen in the community. † (Stanwick & Stanwick 2009).The principle states that employees must protect and preserve public goods or common grounds including sustainability and other environmental issues in order to conduct business in an ethical manner. The tobacco industry’s attempt to appear ethical was transparent as their business practices remained unchanged despite the illusion of addressing the issues. Furthermore the tobacco industry uses CSR to uphold the wellbeing of society despite continuing to produce lethal products. The health effects which occur as a result of using products manufactured by tobacco companies are widespread and in most cases deadly. The tobacco companies are well aware of their products deadly nature however they continue to manufacture and distribute these products.In an effort to repair their image, the tobacco companies used public relations e xploits and funding youth anti-smoking campaigns which have been proven to be ineffective and in fact a heinous marketing tool directed at underage smokers. (Friedman 2009) Tobacco companies have even gone as far to focus their corporate social responsibility tactics at the education sector in the form of scholarships, grants, professorships and even the creation of an entire school (World Health Organisation 2003). This use of corporate social responsibility however was used as more of a defence against public condemnation due to the unchanged nature of their selling practices.On August 17, 2006 the United States District Court found the tobacco industry guilty of a number of allegations of fraud and conspiracy (Friedman 2009). The conduct of the tobacco companies in light of this case was highly unethical in terms of the global business standards codex in particular the dignity principle which states â€Å"Protecting the dignity of people in society includes ensuring the human ri ghts of health, safety and privacy† (Stanwick & Stanwick 2009). Tobacco companies continue to manufacture and distribute products with full knowledge of the products lethal nature when used as directed, using CSR only as a defence against public scrutiny.Clement-Jones (2004) states that no company producing weapons or growing tobacco can ever be truly socially responsible due to the harmful effects of their products indicating that corporate social responsibility can merely be used as a tool of deception and hypocrisy. The tobacco industry’s use of CSR is not only a publicity exploit but a means of self regulation to avoid further government legislation on business and manufacturing practices. By implementing CSR practices into the business conduct of tobacco industry, the companies create a false representation of responsibility for their actions. This however has come under scrutiny from NGO’s as calls for â€Å"international regulation backed up by national l egislation to ensure the enforcement of real social responsibility on the corporate world† (Hirschhorn 2003).Tobacco companies have been some of the first organisations in the early years of the 1900s to realise the value of public relations and gaining support for their industry (Thomson 1998). The tobacco industry’s use of CSR is nothing more than companies protecting their profits and satisfying their shareholders. Hastings & Liberman (2009) state that CSR is another means of promotion and sponsorship for the tobacco companies, by conducting â€Å"socially responsible causes† tobacco companies are able to inadvertently sponsor these causes and promote their products giving further evidence that the tobacco companies have ulterior motives to their use of CSR.The transparency principle of the global business standards codex states that employees are not to operate in a deceptive manner and that business should be conducted openly and honestly (Stanwick & Stanwic k 2009). The tobacco industry fails to follow this principle through their use of CSR as they operate in a deceptive manner. CSR can however be an effective tool for improving an organisations reputation and ethical image such is the case of Alcoa, an Australian based aluminium manufacturing company which improved its standing in the community with effective CSR practices (Black, Sydney-Smith & Zhao 2009). The use of CSR by organisations such as tobacco companies can never truly be an effective strategy as long as the manufacture of harmful products continues under these organisations.Using three principles of the business standards codex as well as the use of CSR by the tobacco industry to secure public support, it has been shown that these strategies have ulterior motives and are purely marketing tools used by these companies to conceal the promotion of their products which is banned by legislation. CSR however can remain a highly effective tool for public relations as long as the intentions of those organisations are beneficial to society.

Learn to Code in 3 Months With Harvards Online Courses

Learn to Code in 3 Months With Harvard's Online Courses Harvard’s â€Å"Introduction to Computer Science† course is widely regarded as the best computer science course online and serves as a rigorous starting point for thousands of online students every year. Plus, the course is flexible: there’s an option for you whether you just want to look around, are dedicated to completing every assignment, or want to earn transferable college credit. Here’s some straight talk: â€Å"Introduction to Computer Science† is hard. It’s designed for students without previous computer programming experience, but it’s no walk in the park. If you enroll, you can expect to spend 10-20 hours on each of the nine project sets in addition to completing a complex final project. But, if you can dedicate the effort required, you’ll gain tangible skills, have a much more in-depth understanding of computer science and develop a better sense of whether or not this is a field you want to pursue.   Ã‚   Introducing Your Professor, David Malan The course is taught by David Malan, an instructor at Harvard University. Before creating the course and teaching at Harvard, David was the Chief Information Officer for Mindset Media. All of David’s Harvard courses are offered as OpenCourseWare – at no cost to the interested public. The primary instruction in â€Å"Introduction to Computer Science† is delivered through David’s videos, which are professionally filmed and often use screens and animation to get the point across. Fortunately, David is both concise and charismatic, making the videos an easy watch for students. (No dry, 2-hours-behind-a-podium lectures here). What You’ll Learn As an introductory course, you’ll learn a little bit of everything. The curriculum is broken down into twelve weeks of intense learning. Each weekly lesson includes an informational video from David Malan (generally filmed with a live student audience). There are also walkthrough videos, in which David directly demonstrates coding processes. Study session review videos are available for students that may be less comfortable with the material and need additional instruction in order to complete the problem sets. Videos and transcripts of videos can be downloaded and watched at your convenience. Lessons introduce students to: binary, algorithms, Boolean expressions, arrays, threads, Linux, C, cryptography, debugging, security, dynamic memory allocation, compiling, assembling, File I/O, hash tables, trees, HTTP, HTML, CSS, PHP, SQL, JavaScript, Ajax, and dozens of other topics. You won’t finish the course as a fluent programmer, but you’ll have a solid understanding of how programming languages work. What You’ll Do One of the reasons â€Å"Introduction to Computer Science† has been so successful is that it gives students the opportunity to apply what they’re learning while they’re learning it. In order to complete the course, students must successfully finish 9 problem sets. Students begin creating simple programs from the very first week. The instructions for completing the problem sets are extremely detailed and even feature extra help videos from past students (proudly wearing their black â€Å"I took CS50† t-shirts for solidarity with the currently-struggling). The final requirement is a self-guided project. Students can choose to create any type of software using the skills and programming languages they’ve learned throughout the course. Enrolled students submit their final project to an online fair – after the class is over, projects are shared through a website for peers to see what everyone else has been up to. Students needing extra assistance can work with Harvard tutors online for $50 an hour. Did You Want a Certificate With That? Whether you just want to take a peek at the course or want to earn college credit, â€Å"Introduction to Computer Science† has an option to help you get started coding. EdX is the easiest way to access course materials at your own pace. You can sign up for free to audit the course, with full access to videos, instructions, etc. You can also opt to donate $90 or more for a Verified Certificate of Achievement upon completion of all coursework. This can be listed on a resume or used in a portfolio, but will not give you college credit. You can also view course materials on CS50.tv, YouTube, or iTunes U. Alternatively, you can take the same online course through Harvard Extension School for about $2050. Through this more traditional online program, you will enroll with a cohort of students during the Spring or Fall semester, meet deadlines, and earn transferable college credit upon completion of the course.

Trumans decision to drop the essays

Truman's decision to drop the essays The assessments of western civilization and culture has in one way or another affected virtually every aspect of life on the globe. The changes and ideas of this way of thinking have gradually evolved over the past six centuries and are still incredibly visible, dominant, and crucial in the twentieth century. A large portion of the changes created and reinforced by this movement have been beneficial, while still some seem to have left more of a negative effect on the world. Overall, the changes brought about by western civilization in the past six hundred years have resulted in significant advancements and giant steps taken forward in the direct of a better world, in particular, a world where spirituality continues to thrive. Aleksandr Solzhenitsyn, a very well respected twentieth century Russian philosopher, once said this about the progress of western civilization: "On the way from the Renaissance to our days we have enriched our experience, but we have lost the concept of a Supreme Complete Entity which used to restrain our passions and our irresponsibility. We have placed too much in politics and social reforms, only to find out that we were being deprived of our most precious possession: our spiritual life."1 There certainly is some truth in Solzhenitsyns statement and approach to western civilization. Many aspects of our society reflect a direct crisis in morality. Everywhere we turn our heads and look we see: babies being aborted, premarital sex being promoted, drug use ski-rocketing, and extreme violence being used as a form of entertainment. From the perspective of many others, our society tends be incredibly self-centered and materialistic. This, of course, is also a logical assumption seeing a s how money is so sought after, and how possessions seem to be directly tied in with a persons status. Some people go through their entire lives striving to obtain the most high paying and sought after jobs, the fanciest ...

What You Need to Know About Consecutive Numbers

What You Need to Know About Consecutive Numbers The concept of consecutive numbers may seem straightforward, but if you search the internet, youll find slightly differing views about what this term means. Consecutive numbers  are numbers that follow each other in order from smallest to largest, in regular counting order, notes  Study.com. Put another way,  consecutive numbers are numbers that  follow each other in order, without gaps, from smallest to largest, according to  MathIsFun. And  Wolfram MathWorld  notes: Consecutive numbers (or more properly, consecutive  Ã¢â‚¬â€¹integers) are integers n1  and n2  such that n2–n1   1 such that n2 follows immediately after n1.​ Algebra problems often ask about properties of consecutive odd or even numbers, or consecutive numbers that increase by multiples of three, such as 3, 6, 9, 12. Learning about consecutive numbers, then, is a bit trickier than is at first apparent. Yet it is an important concept to understand in math, particularly in algebra. Consecutive Number Basics The numbers 3, 6, 9 are not consecutive numbers, but they are consecutive multiples of 3, which means that the numbers are adjacent integers. A problem may ask about consecutive even numbers- 2, 4, 6, 8, 10- or consecutive odd numbers- 13, 15, 17- where you take one even number and then the very next even number after that or one odd number and the very next odd number. To represent consecutive numbers algebraically, let one of the numbers be x. Then  the next consecutive numbers would be x 1, x 2, and x 3. If the question calls for consecutive even numbers, you would have to ensure that the first number you choose is even. You can do this by letting the first number be 2x instead of x. Take care when selecting the next consecutive even number, though. It is  not  2x 1 since that would not be an even number. Instead, your next even numbers would be 2x 2,  2x 4, and 2x 6. Similarly, consecutive odd numbers would take the form: 2x 1, 2x 3, and 2x 5. Examples of Consecutive Numbers Suppose the sum of two consecutive numbers is 13. What are the numbers? To solve the problem, let the first number be x and the second number be x 1. Then: x ( x 1) 132x 1 132x 12x 6 So, your numbers are 6 and 7. An Alternate Calculation Suppose you had chosen your consecutive numbers differently from the start. In that case, let the first number be x - 3, and the second number be x - 4. These numbers are still consecutive numbers: one comes directly after the other, as follows: (x - 3) (x - 4) 132x - 7 132x 20x 10 Here  you find that x equals 10, while in the previous problem, x was equal to 6. To clear up this seeming discrepancy, substitute 10 for x, as follows: 10 - 3 710 - 4 6 You then have the same answer as in the previous problem. Sometimes  it may be easier if you choose different variables for your consecutive numbers. For example, if you had a problem involving the product of five consecutive numbers, you could calculate it using either of the following two methods: x (x 1) (x 2) (x 3) (x 4)or(x - 2) (x - 1) (x) (x 1) (x 2) The second equation is easier to calculate, however, because it can take advantage of the properties of the  difference of squares. Consecutive Number Questions Try these consecutive number problems. Even if you can figure out some of them without the methods discussed previously, try them using consecutive variables for practice: Four consecutive even numbers have a sum of 92. What are the numbers?Five consecutive numbers have a sum of zero. What are the numbers?Two consecutive odd numbers have a product of 35. What are the numbers?Three consecutive multiples of five have a sum of 75. What are the numbers?The product of two consecutive numbers is 12. What are the numbers?If the sum of four consecutive integers is 46, what are the numbers?The sum of five consecutive even integers is 50. What are the numbers?If you subtract the sum of two consecutive numbers from the product of the same two numbers, the answer is 5. What are the numbers?Do there exist two consecutive odd numbers with a product of 52?Do there exist seven consecutive integers with a sum of 130? Solutions 20, 22, 24, 26-2, -1, 0, 1, 25, 720, 25, 303, 410, 11, 12, 136, 8, 10, 12, 14-2 and -1 OR 3 and 4No. Setting up equations and solving leads to a non-integer solution for x.No. Setting up equations and solving leads to a non-integer solution for x.

Fundraising Coursework Example | Topics and Well Written Essays - 1000 words

Fundraising - Coursework Example Sudden cardiac arrests causing sudden death have mainly occurred due to incompetency and ignorance of individuals witnessing cardiac arrests. Thus, if more people are aware of cardiac arrests and know what to do in case they are around a person having cardiac attack, more chances would be to grant those suffering their survival. VSF is one organization, whose aim is to raise awareness of Sudden Adult Death Syndrome and cardiac arrests. However, there are some other charity organizations involved in raising awareness Sudden Adult Death Syndrome and developing action guidelines. NHS and Raising Awareness of SADS Although logically would be to suggest that the major organization to raise awareness of Sudden Adult Death Syndrome and ways to prevent or diagnose it early would be National Healthcare System, the truth is that NHS establishments are preoccupied with a vast variety of diseases and their treatment. Consequently, less attention is paid to the problem of Sudden Adult Death Syndr ome solely. ... Organizations involved in raising awareness of SADS Despite that NHS is not actively involved in raising awareness of Sudden Adult Death Syndrome and developing guidelines on how to act, there are charitable organizations that are devoted to the cause. These organizations were established majorly by relatives of those who died in result of Sudden Adult Death Syndrome. Among such organizations are Sudden Death Support Association and SADS – Sudden arrhythmic death syndrome (http://www.sads.org.uk/), who raise awareness and provide support for families, and Ashley Jolly Sudden Adult Death Trust (http://www.sadsuk.org/), Cardiac Risk in Young (CRY: http://www.c-r-y.org.uk/) who raise awareness of the disease, support the families who have gone through deaths of loves ones, and are involved in fundraising for the cause to equip local communities, colleges, schools with automated external defibrillators (Patient UK, 2011). Awareness of Sudden Adult Death Syndrome is also raised thr ough booklets and events from British Heart Foundation, which provides information on cardiac illnesses including SADS. SADS UK – The Ashley Jolly Sad Trust According to the official website, â€Å"The Ashley Jolly Sad Trust (SADS UK) is a voluntary organization that exists to raise awareness about little known heart conditions in young people and provides information and support to families who have experienced the sudden unexpected death of a loved one due to such a condition. The Trust fundraises to purchase and donate heart monitoring equipment to detect potentially fatal heart conditions in order that once a condition is identified the patient can be referred to a cardiologist for treatment, to minimize the risk of sudden premature death.†

Annotated Bibliography on The Obama administration's policy lifting

On The Obama administration's policy lifting the prohibition of women from serving in combat roles - Annotated Bibliography Example It further displays their immense roles calling for a redefinition of women roles in ground combats. Davis, Robert et al. "This research was sponsored by the National Institute of Justice and was conducted in the RAND Center on Quality Policing within the Safety and Justice Program of RAND Infrastructure, Safety, and Environment." (2011). this is a research paper that was conducted by the national institute of justice at the RAND center to access the quality of decisions that are often made by the executive organs in various organizations. In view of the ban the paper reviews its suitability an applicability bearing in mind the delicate nature of women serving in ground combats. The paper shows concern on safety upon implementation of such policies. In addition, the paper undertakes a review to ascertain implementation policies that have so far been passed such as the 1990’s ban on women flying in combat and serving in war ships. Miller, Laura et al. The Extent of Restrictions on the Service of Active-Component Military Women; Rand National Defense Research Institute: Santa Monica, 2012. This is a review by the Rand Defense Research Institute. The paper investigates the harm that a restriction on women serving in combat positions affects the entire military operations. The paper argues that although restriction of women can yield better results, it can as well yield poor results since some women are more talented in ground combat more than their male counterparts. It further stresses that when women are accepted to work in a free environment they are more likely to have their military experience boosted. Skein, Rosemarie. Women in Combat: A Reference Handbook. Santa Barbara: ABC-CLIO, 2011. This is a handbook that outlines proposals and measures that should be put in place to ensure fair participation of women service in combat positions in the military. In this regard, the paper bases its arguments on the ban

Male circumcision as an hiv control stategies and not a natural condom Essay

Male circumcision as an hiv control stategies and not a natural condom - Essay Example Reproductive Health Matters, the safest way to prevent HIV infections is still to use a condom rather than relying on assumptions which are yet to be proven sufficiently (Bonner, 2001). Bonner is of the opinion that unless certain facts are not proven practically, it is unwise to adopt and follow such assumptions. The facts to be proven encompass umpteenth number of issues such as the reason and the way how circumcision is risk-free, the exact relationship between circumcision status and the remaining STIs (Sexually Transmitted Infections). Also, Bonner is still waiting for an answer backed by sufficient evidence that whether or not positive result found in high-risk populations will reap equal results in case of other general groups. However, according to Updegrove, various conclusions insist that uncircumcised males tend to suffer from higher rates of sexually transmitted diseases (Updegrove, 2001). The same has been coherently acknowledged by Ronald Gray and his team with similar mindset (Gray, Kigozi & Serwadda, et al, 2007). Other think-tanks, Bailey, Plummer and Moses, all consider circumcision as an anti-HIV measure (Bailey, Plummer & Moses, 2001). Newell and Barnighausen have gone on to confirm that male circumcision cuts down HIV risk even in the general population (Newell & Barnighausen, 2007). Nevertheless, it should be noted that all the above think-tanks do reveal a certain level of uncertainty in expressing their perspectives. Hence, the two completely distinct recommendations; whether or not to replace condoms with circumcision appear to be a highly perplexing issue. Bonner highlights an investigation according to which circumcised men reveal higher occurrence of genital discharge (Bonner, 2001). He puts forward a French report which reveals that both circumcised as well as uncircumcised men exhibit almost same state of HPV incidence which plays a vital role in cervical cancer (Bonner, 2001). By referencing an American case, Bonner diligently

Uninvolved Parents Essay Example | Topics and Well Written Essays - 500 words

Uninvolved Parents - Essay Example The essay "Uninvolved Parents" overviews the categories of parents behavior with their children – authoritarian, permissive, authoritative or uninvolved, though concentrating on the uninvolved one. Some of these categories have a positive effect in molding the character of children, and others less so, but none of these is as destructive to children as uninvolved parents. Uninvolved parents are completely uninterested in the welfare of their children, and they are dismissive and non-caring. They disregard their children completely as far as the emotional attachment is concerned. Sometimes, they event neglect the basic needs of their children when it comes to their wishes vs. their children. My childhood and teenage are a story filled with exactly this – neglect, exploitation, and even abuse, mental, physical as well as sexual. My parents inherited big through the death of my grandfather, which made them go into the drugs business. They became addicts themselves and dealt in drugs through the home. They even forced me and my sister to tend to the dealers that came by the house for the drugs. There was a lot of money that my parents inherited, but we still had no running water, no electricity, no food, tons of roaches, and fleas in our house. Our drugged parents were totally detached from our well-being. We had no value in their lives. All my father did be scaring us and using us. Not only did we deal with physical beatings but also we had to endure our father’s sexual abuse.

Business report based on the a given case study. Highland Limited Essay

Business report based on the a given case study. Highland Limited - Essay Example Frank in order to repay the loan had to sell of his centre at Shiel Bridge. Frank Rose took help from his wife Fiona and Andrew Robertson who were willing to put in funds and thereafter Fiona and Andrew took over the running of the business. Frank Rose concentrated more on the Outdoor Centre while Fiona looked after the accounts and Andrew became the Managing Director. The business operated from small cottage. The company moved into a new location in April 2008 and one of the main customers of Highland Limited, Weir’s of Glasgow made the company big enough to get viable. The relationships between the staff were informal. But steadily the employment increased post November 2008. The company did not have enough resources to meet the demands of the market and thus the company did not make any attempt to attract new customs. Approaches to retailers were discouraged as Andrew Robertson believed that until they had the capacity to satisfy the demands of the market it would not be pr ofitable to go to the retailers. The company faced a twist when it had started operating with Stoner garment, a brand of western Oil Limited. The company was eager to supply waterproof and protective clothing to the lucrative market of about 2000 workers. This provided Highland Limited with an advantage as being a local supplier the company would be able to produce jackets according to the demands and deliver at a minimal time. Therefore Highland Limited together with Stoner Garments decided to design jackets which would be acceptable to Western Oil in terms of both quality and price. Therefore by providing garments to the Western Oil the company was able to achieve success and the legal framework adopted by the company was applying the norms and regulation. Highland Limited was a company in which philosophy and raison d’etre mattered a great deal. The company realised that although the company objectives was to maximise the profits there were also secondary objectives which the company also wished to pursue. The objectives were embodied in the company’s philosophy but never written down. There was difference in the way people saw the philosophy. Thus the factors that the organisation needs to consider in reviewing its mission statement, goals and business plans for the future is firstly the company needs to develop a mission statement, a mission statement is only the starting point of the organisation. Next task is to identify a set of goals which would accomplish the organisations missions. The company needs to establish one year plan, three year and five year plan for expanding its market share in the market. Thus to achieve the goals the company have to develop short term objectives

Uninvolved Parents Essay Example | Topics and Well Written Essays - 500 words

Uninvolved Parents - Essay Example The essay "Uninvolved Parents" overviews the categories of parents behavior with their children – authoritarian, permissive, authoritative or uninvolved, though concentrating on the uninvolved one. Some of these categories have a positive effect in molding the character of children, and others less so, but none of these is as destructive to children as uninvolved parents. Uninvolved parents are completely uninterested in the welfare of their children, and they are dismissive and non-caring. They disregard their children completely as far as the emotional attachment is concerned. Sometimes, they event neglect the basic needs of their children when it comes to their wishes vs. their children. My childhood and teenage are a story filled with exactly this – neglect, exploitation, and even abuse, mental, physical as well as sexual. My parents inherited big through the death of my grandfather, which made them go into the drugs business. They became addicts themselves and dealt in drugs through the home. They even forced me and my sister to tend to the dealers that came by the house for the drugs. There was a lot of money that my parents inherited, but we still had no running water, no electricity, no food, tons of roaches, and fleas in our house. Our drugged parents were totally detached from our well-being. We had no value in their lives. All my father did be scaring us and using us. Not only did we deal with physical beatings but also we had to endure our father’s sexual abuse.

Native American Heritage Essay Example for Free

Native American Heritage Essay I have re-read this book in a relatively new edition. It is a mixture of Kiowa myths, family stories, history sketches, and personal experiences. For me it evokes a sense of community unknown in modern U. S. society. It also conveys, however dimly to the modern scientific mind, a deep sense of a peoples experience of the sacred where that term is entirely outside of modern theology and is steeped in the land and the memory of a people. It one opens ones mind and emotions the book can connect in a powerful way. However, a modern can never penetrate to the full depth of Kiowa sensibility. This was harshly expressed in an art object in the IAIA in Santa Fe, New Mexico some years ago. The object included the words: Just because you stick a feather in your hat doent make you a Indian. of another edition It seems enough to alert the reader this book exists, in case anybody is tired of consumer infatuation.

Thats the difference between being a bear and wearing a Jordan t-shirt with Hanes underwear. Nobody is Jordaned or Meadow Lark Lemoned from a laying on of their hands, but bear will move you. Dress in any of these masks or be naked as yourself as He Who Wears Only His Name. Either you stand naked in The Name or you hide in a mask. Groups function as masks to prevent nakedness, as if there were something other than The Name to stand in, but for the human there isnt. It might be the landscape and the racial memory of landscape that my parents and grandparents knew (Schubnell, Conversations, 46). I feel deeply about the landscape and I mean that literally. I think it is important for a person to come to terms with landscape. I think thats important; it is a means to knowing oneself (45). So it comes down to the meaning of landscape too, but this is intellectualized. The real question is, what is the meaning of wilderness? Superficial Existence in the Modern World Much of this is foreign today, Bear, landscape, even ancestry have been substituted with identities of no purpose to examine. The annihilation of the traditional in tribal societies and every assimilated subgroup is a negative. Assimilation is never good, although to say it that bald is offensive. This is also the point in that First Convocation of Indian Scholars (Ed.by Rupert Costo, 1970). In answering Hopi Charles Loloma about how to assume the traditional identity Momaday says, I think that each of us who realizes that the native traditional values are important has a great obligation to convince the young of that, who may be wavering with alternatives [of] the dominant society which is destroying the world in which it lives (9). Its really up to the older people(10) to identify the danger of superficial existence in the modern world (10). To counter superficial existence he says they have a primary obligation to tell their children and grandchildren about the traditional world, and try to show them by example and tell them explicitly that there is an option available to them, and that theyre damn fools if they dont avail themselves of it (10). Acculturation Thus acculturation is a kind of one-way process in which the Indian ceases to be an Indian and becomes white man (10). It is broader than that too, the PA German ceased to be himself and became an English-American. Acculturation to the modern translated means to steal the birth rite identity of the traditional, its language and customs and make the native a mascot of the modern. There is a continual excavation of the Caucasoid in every subgroup that assimilates, whether Pennsylvania German, Hispanic, black, Indian. The anthropologists should excavate themselves to give them something to do, since they otherwise are the inventors and stalking horse for the modern against the traditional, looking for power by stealing it. Modern here is not the pejorative it seems if the native takes his tradition into it to return what is stolen, or as Momaday says, that it is good to go into the enemys camp (12). Steal his horses! But he has stolen the children! Pull Out the Light Poles That said, it remains to learn tradition from the elder. In the face of radical destruction this takes more than effort, it takes surrender. Without surrender the traditional dies. Take your pick, you can think like Katie Couric and all the like spokespersons for the modern on Charlie Rose, or like grandfather. Momaday says it is a duty to teach the young. He addresses the elders reluctance: I wonder if you have any idea of why they shut up at a certain point like that, why they wont talk to you (15)? Charles Loloma, the Hopi, had said that when the power company installed electric poles by force the people came out and pulled the poles all back out. These people didnt want the electricity'(15). This is symbolic of the whole transmission of culture of the modern against the traditional. When the enemy enters the native camp it is called deliverance, but is really theft of the child. It is destruction of the tradition, which is obvious when white missionaries go to New Guinea but apparently not when the Internet sells social network. You have to live it, not be curious of it. Fight Against Electricity! Ben Barney, a Navajo, says he had a grandfather who taught him until the age of eight, but when he died he couldnt find a replacement. Another says, my grandfather died, and he was one of the last men in the village who knew the whole ritual cycle of songs. He died without letting me or my father, or any of us record any of it. I think he felt that this thing that he had was too precious to just give out, and have it exposed to someone whom he never knew well. And hed rather die with it than have that happen to it. It seems to me he was saying, youre not going to to live it. Youre one of these people thats fighting for the electricity. (I am not, in fact) (17). So the ticket to the traditional, the universal (! ) is that you have to live it, not be curious of it. Surrender to the traditional! If you will not surrender, and the elders have any pride, they take it to the grave in sorrow. But it is not to be studied by post docs. It is to be lived. How many young think their elders outweigh the modern? Lifeway That you have to live it goes a long way toward knowing both wilderness and identity. Living is not an intellectual function. But he was saying, youre one of these people who are fighting for this. My people never had electricity. We never lived that way. And if I give you my lifeway, if I tell you my lifeway, youre going to sit and laugh at me, because youre laughing anyhow just by your behavior (17). Only among the remnants of American tribes does anyone dare thus to challenge the modern. Other subgroups embrace it like a drug. The life way is an iPhone. The elders wont speak to this, naturally they are not going to tell you. I mean, they cant. I can see why he felt there is no way to communicate experience; the essence of it, the reality of it. I believe he was saying: I could give you words, and you could put them down, but that wouldnt mean the same thing (17). Is this reality versus the virtual? The track of a bear versus a video game? These things are important if you want to have anything left on the earth that isnt homogeneous and interchangeable. Like babies. Everything said here of the American tribes transfers to every family and subculture. 2. Momaday avoids the satiric in his work, but it is a satiric haunt like a ghost river in every meadow, grove and stream the summer nights after the predators came. Then a foam appeared at the exit pipes of plants along the upper Allegheny. It is hard enough to name Bear and Wilderness when those subsequent masks upon masks cover up naked being. Surrender. Stand up and strip, confess, then kneel! Wilderness trees, canyons, streams and things under and in them, screeches in the night, wheat, bear, porcupine are symbols to show what they are standing for, something else, life mirrors that open doors and close the way we live. Only the sun has escaped our dominion. The sun escaped the nano tales that seine the atmosphere in a net, to take earth away. How To Know and Recognize the Alien These image masks are the ultimate reality that deny we are predators or aliens. If you want to know the alien go and be one. Sit in the Mogollon. Do you belong? Find a bear. Is he your friend? People wander out all the time, light fires to be found, but the ones that arent found bone up. Coyote Wound Dresser had a talk with Walt Whitman, Wound Dresser, but things did not turn out well for Whitman. The alien cannot be modeled, but it is knowable if Unknown. Im going to tell you what it is. Talking to the Unknown we try to understand synergies of it in the anthropology of Edward Dorn http://osnapper. typepad. com/snappersj He says the alien is a crucifying self-consciousness of doubt at the root of his own being when he sees the Shoshone. Does he, Dorn, belong? His doubts serve against the Unknown. They are a mirror of loss and lack. The filth on the chair that gets on his pants is an image of it I had a great desire to be off, to not take any more, or give any morefor I will say it, at the risk of blunder: It is impossible for myself and my people to offer themselves in any but the standard senses (14). At least he knows of the surrender, that you have to live it. In some freak of Methodism he wants to wash this old mans feet to tame him, this 102 year old who stands for all of Idaho, Utah, Nevada and the Great Basin before electricity, a volume of Yaa-Aaa-Aaa (14). I was aware of the presumption of my thinking he would be relieved or made happy by having his feet washed (13). Now Here is the Alien: If you want to confront the Unknown you must to do it in the feet of your old age and death. If we want to confront the Unknown we must to do it in the feet of our old age and death. The place was intensely neglected, I gradually saw, and not just filthy as it looked to be at first glance. It was simply the remains of a life (12). The comfort of the Unknown in Dorns account is that there are two that serve each other in it, but we dont know why. One Unknown is the wife, ust like all our mothers and wives, who should have died, by the rules of our biology, thirty years ago. But it was evident that she would stay on, the weaker of the two, until he smelled the summary message in his nostrils, then she would be free (12). Is death that freedom? The alien doesnt think in known terms, but makes Dorn harbor such thoughts as, this man and woman were the most profoundly beautiful ancestors Ive witnessed go before me (12,13). He is the spirit that lies at the bottom, where we have our feet. The feet which step between the domains, the visible sign, the real evidence of the coming event where this mans low, incantatory verbs spill down across the plateau and basin (13)not more Indian than man, still as much the flower as the fruit. Wash his feet! Wash his hands, heart and head! Lay in the dust like a penitent Barry Lopez, close to the flagellate, and weep for the human lost. This Shoshones name is Willie Dorsey. We dont get his real name, Alien. I saw, the heat, the vociferous mosquitoes in the buildings shade, the slightly moist filth at the back door. Alien old age and death look like very old animals [that] have such coats over the eyes, a privacy impenetrable from the outside (11). Cataracts, the blind, the lame, the sick, the living I know treated by some Doctor of the Alien. She operates her office practically as a charity, complete with science, intuition and healing to the grim weight of bad condition, not especially outlined, more heavy with despair than one could possibly arrange with rubble (11). This is not Ed Dorn. He is a spectator. This Doctor holds the hand, cuts the hair, absorbs the breast, the tear, weeping and praying within, but praising and thanking for the chance that comes out of the wooden clapboard structures (10) of lives that they could be so treated and revived. So thats the alien, its human and knowable even if Unknown. Poetry Analysis Sherman Alexie is Spokane/Coeur dAlene Indian. Alexie wrote a poem called â€Å"The Reservation Cab Driver†. The title contributes to understand the poem and understand who the cab driver was. In this poem, Alexie uses a symbolism he also uses some metaphor, irony and imagery. By examining the life portrayal in the reservation, the poem’s casual diction, the magic appearance of Crazy Horse, I will show how Alexie’s critique of the status of Indians on the reservation. The life in the reservation was hard. When anyone wanted to get out of the reservation the only choice the reservation had was hiring the cab driver who drives a ’65 Malibu with no windshield. The description of this cab driver car is an example of Imagery taking place you can see the car all beat up with no windshield. This particular cab driver waits outside the breakaway bar. He charges his costumers a beer a mile with no exception. This cab driver is not looking for money. The other people have to get this cab to take them places especially during the powwow. Also in stanza 8 during powwow, some imagery takes place. The imagery you see is people paying him with quilts, beads and fry bread and firewood. Imagery in this section is important because you can see what’s going on. In this stanza the imagery is very clear that it seems as if you are there in person watching everything. Also in stanza 7 you see use of metaphor also irony but the cab driver did not understand Seymour because the cab driver answers â€Å"Ain’t no pony, it’s a car†. Alexie shows us how hard it is for the reservation to have to take the cab and pay in a form that you do not see in other places of America. Alexie shows us an example of two different economies. Within the same country but how life in the reservation is completely different to the rest of the life outside the reservation. The reservation has many problems like having only one cab driver who charges a beer and a cigarette a mile. Another problem â€Å"The Man to Send Rain Clouds† The theme of Leslie Marmon Silko’s The Man to Send Rain Clouds revolves around the idea of maintaining your culture in the opposition of the â€Å"religious right. † Leon is faced with strong opposition about his tribe’s rituals in regard to the burying of one of their dead. That opposition comes from the Christian priest and his ideas of what is sacred. Cultures around the world embrace death in different ways. Some mourn and fear death; others accept it and find hope when the time comes. Unfortunately not all of those cultures are able to be open to the idea that they could be wrong, or that different methods could lead to the same ends. The Christian church of coarse has a history of killing, burning, and condemning things that disagree with their ideologies. Even today we see extremists in many religions that fight wars over their beliefs. In this story a man had to fight with himself regarding the decision. He has to wrestle with the pleas of the priest and the idea that his culture taught him regarding death. He believed as his tribe did that the ritual would bring rain and new life to the crops. The battle between cultures moves on when the priest is actually asked to be a part of the ritual and bless the body. At this point the priest enters his own battle with the things that he was taught and the opposition that he faces. He had to decide what would be the Christian thing to do. When all these battle are over both men learn a little about each other’s world as the wind starts to come in, it is a wind of change. They wait to see if the storm will come to begin the circle of life anew. The Man to Send Rain Clouds Readers Reaction This was quite an interesting story. There were three sections to the story which broke the story in three different times in one day. The characters were all very nonchalant except for the priest who showed some emotion when he found out that old Teofilo died. The story kept our interest, however, it did not lead a very clear trail to the end, and there was no real climax where we felt there was a good peak. The story needs to be read more than once to really be appreciated. Plot Summary One ? Teofilo is at the sheep camp in the arroyo when he rests in the shade under a cotton tree and dies. ? After Teofilo missing for a few days, Leon and Ken come looking for him and find that he had been dead for a day or more, and the sheep had wandered and scattered up and down the arroyo. ? They gather the sheep and then come back to wrap Teofilo up in a red blanket. ? They paint his face with different colors and ask him to send them rain. ? On Leon and Kens way back into pueblow (town) they see Father Paul, who asked if they found their missing grandfather yet, and they tell him where they found him, but not that hes dead. Good Morning, father. We were just out to the sheep camp. Everything is o. k. now. Two ? Louise and Teresa are waiting for them to get back with any news about Teofilo. ? Leon tells the girls that they found Teofilo died near a cottonwood tree in the big arroyo near sheep camp. ? Leon and Ken carry in red blanket with teofilos body, dress him in new clothes to be buried in. ? After a quiet lunch, Ken went to see when the gravediggers could have the grave ready, I think it can be ready before dark. ? Neighbors and clans people come by their house to console Teofilos family and leave food for the gravediggers. Three ? After the funeral, Louise tells her brother Leon that she wants the priest to sprinkle holy water for grandpa. So he wont be thirsty. ? Leon gets in the truck Burial Rituals of Native American Culture At some point in our lives, we all come to realize that death is a part of life. Cultural diversity provides a wide variety of lifestyles and traditions for each of the unique groups of people in our world. Within these different cultures, the rituals associated with death and burial can also be uniquely diverse. Many consider ritualistic traditions that differ from their own to be somewhat strange and often perceive them as unnatural. A prime example would be the burial rituals of the Native American people. Leslie Marmon Silko’s story entitled The Man to Send Rain Clouds describes a funeral service carried out by a Native American Pueblo family. Though many perceive the funeral service narrated in this story to be lacking in emotion and also lacking respect for the passing of their loved one, it portrays a ceremony that is quite common for the Native American communities. There is also a hint of conflict occurring between the characters in the story that are carrying out their traditions while including an outside religious figure in the ceremony. The death of an old man sets the stage for this story and tells of the way his family goes about preparing him for his journey into the afterlife. A feather is tied into the old man’s hair, his face was painted with blue, yellow, green and white paint, pinches of corn meal and pollen were tossed into the wind and finally his body was wrapped in a red blanket prior to being transported. According to Releasing the Spirit: A Lesson in Native American Funeral Rituals by Gary F. Santillanes, â€Å"Pueblo Indians care for their own dead with no funeral director involved. The family will take the deceased, usually in their truck, back to the home of the deceased and place him or her on the floor facing east to west, on a native blanket. Depending on the deceaseds stature in the tribe, his face may be painted in the traditional nature. A powdery substance is placed AK English 217 – Reading Journal (The Way To Rainy Mountain) Scott Momaday uses nature to dictate the passage of life. He personifies the landscape as a person, he says the there is ‘perfect in the mountains but it belongs to the eagle and the elk, the badger and the bear. ’ To me, this tells me the mountains have a feeling of openness, but it is the home of many – not just humans. The mountain holds importance to the Kiowa’s because it is pure wilderness. The landscape that is described helps the reader recognize what the Kiowa’s were thinking upon reaching rainy mountain. The beautiful sights of the land made the Kiowa’s recognize a new passage of life. Their curiosity of the land’s landscape created legends in their tribe. The legends helped them escape through the wilderness by becoming part of it – through kinsmen in the sky and a boy turned into a bear at Devil’s Tower. Momaday describes the curiosity of the wilderness throughout the landscape. In order to build the larger idea of the tribe, the curiosity makes the landscape act as a character. The writer, Scott Momaday, describes the grandmother through details of her life. My favorite line was at the end when he wrote, â€Å"There, we it ought to be at the end of a long and legendary way, was my grandmother’sgrave. † This line sums up her entire life in a single sentence. She lived a long life and saw many things, her life was filled of legends that the tribe created. She had a reverence for the sun because she saw the Sun Dances when she was younger. In 1887, the grandmother was at the last sun dance; she bore a vision of deicide without any bitterness. At an old age, she began praying frequently. Momaday could not understand what she was saying but describes the tone of her voice as ‘sad in sound, some merest hesitation upon the syllables of sorrow. ’ No matter what the language, people inherently understand the sounds of sadness. It really brought the grandmother to life. Then finally, at the end, he Many Americans today believe that all students –no matter what race or ethnicity- have an easy path with our education and that all students are able to get a higher education without any problems. Yet this belief is not true for all students. However it’s a whole different story for the working class students. The working class student that goes for a higher education in life, in search for a better life and, a brighter future are faced with many obstacles and challenges on their path to achieve their goals and dreams. The working class students are put with many different challenges. As they the working class students goes forward with their education, there maybe people that will try to put them down in many forms. But you should know that you will survive and at the end you be a stronger, prepare student with the tools to overcome any obstacles in life. In the article â€Å"Indian Education† by Sherman Alexie, we read how being working class students we have obstacles to overcome. Some of this obstacles come from the people we less expected just like the example in Alexie Sherman Article â€Å"Indian Education†, how his own second grade teacher Miss Betty Towle try to put him down as many times as possible. She the teacher tries to put him down for being Indian, and for having working class parents. The Teacher Miss. Betty seems to not care for Alexie at all. The teacher ask Alexie to give a letter to his parents in which she ask for his parents to come to school so that they could have a conversation on what she calls his bad behavior in class. The teacher seems to not want to talk about his bad behavior. Instead, she wanted to insult Alexie in front of his parents by calling him Indian without any compassion or respect. â€Å"Indians, indians, indians, she said it without capitalization, she called me Indian, indian, Indian† (p. 1). Base on this citation we see that the teacher was trying to put him down for being Indian and for having parents that weren’t educated. By

Thin Layer Chromatography for Composition of Analgesics

Thin Layer Chromatography for Composition of Analgesics THIN LAYER CHROMATOGRAPHY HALILI, Johanna Bernadette C. ABSTRACT In this experiment, a thin-layer chromatography (TLC) was used to determine the composition of different analgesic drugs which were Aspirin, Ibuprofen, Caffeine, Paracetamol, tea sample and an unknown substance. Chromatography takes advantage of the fact that different substances are partitioned between two phases. TLC is used to identify individual components in a mixture. These chromatography techniques focused on the fact that components of a mixture tend to move at different speeds along the flat surface from the paper used to separate from each other. The results obtained by comparing the spots and after performing the experiment, the unknown was identified to be Aspirin. INTRODUCTION Thin-layer chromatography (TLC) is one of the most important techniques in organic chemistry and is used for the rapid separation and qualitative analysis of different substances (Pavia, et. al., 2010). This separation technique is accomplished by the combination of the mixture between two phases: the stationary and the mobile phase. The stationary phase or the absorbent, which is usually silica or alumina, is coated on a supporting material which is either a glass or plastic. The sample is applied to the layer of the adsorbent coated sheet or TLC plate. The mobile phase, or the solvent called the eluant, travels up the absorbent by capillary action (Ault, 1998; Miller, 2005). As the solvent passes through the sample or spot, it shows the effects of separation of the material in the spot. This separation technique is also used to identify if substances are pure and to compare it with other samples. Unknown substances can be also determined by comparing an unknown compound’s be havior with the other known substances. In this experiment, thin-layer chromatography is used to determine the qualitative compositions of over-the-counter analgesic drugs. The objectives for the experiment are to observe the different analgesic drugs, to perform thin-layer chromatography and calculate Rf values and to use thin-layer chromatography to identify the analgesic compound present in an unknown sample. METHODOLOGY The group prepared a chamber for the experiment of thin layer chromatography for analgesic drugs. The chamber consists of a filter paper wrapped around the 50 ml beaker with a small opening left for viewing. A 3 ml solvent mixture (25 parts ethyl acetate, 1 part ethanol, and 1 part acetic acid) was added to the chamber and was later covered using a watch glass to provide an atmosphere saturated with solvent inside the container. The filter paper was moistened for the solvent to rise equally. While the chamber was set aside, a silica gel coated TLC plate was obtained and using a pencil, a very light line was drawn across the sheet, about 10 mm from one end Seven small light marks were made along the line and labelled A to G. Each letter correspond to seven analgesic drugs which are aspirin, ibuprofen, caffeine, paracetamol, sample tea extract collected from one previous experiment, an unknown substance and co-spot respectively. Using a capillary tube, small spots of each sample was placed exactly in the intersection of the horizontal line and the tick marks for each letter to make sure it will not mix with the other samples. The capillary tube was cleaned by using Dichloromethane and it was done three times. For the sample E or the tea extract from the experiment â€Å"Isolation of caffeine from tea leaves†, the filter paper that contained the caffeine extracts was rinsed with dichloromethane to be able to place a spot to the TLC. The spots on the TLC plate were al lowed to dry for 1-2 minutes. As soon as the spots were dry, the TLC plate was dropped vertically to an upright position making sure that the chamber is on a stationary place and was covered again using a watch glass. The liquid slowly moved up the TLC sheet. When 80-90% of the solvent had already gone up of the TLC plate, the TLC plate was immediately removed taking note of where the solvent was last seen. Immediately, the TLC plate was marked where the solvent was last seen. The plate was air-dried and it was observed under UV light to point out where the spots are. While observing under the UV lamp, a light pencil mark was marked around each spot in the TLC plate. RESULTS AND DISCUSSION Results Figure 1. Silica Gel coated TLC plate results. Figure 2. Silica Gel coated TLC plate results under UV light. Table 1. Measurement of the distances of the spots in the TLC plate and computed Rf values. Distance travelled by the solvent: 30.0 mm Discussion The objective of this experiment was to perform thin layer chromatography to test a certain substance of its purity or impurity and also to know the analgesic present in an unknown substance. The results shows that 5 out of 7 analgesics had 2 or more spots which indicates that are impurities or there are different compounds in those analgesic drugs. The different analgesic drugs that were observed to have 2 or more spots were Aspirin, Ibuprofen, Paracetamol, the unknown substance and the co-spot. Rf values were also computed by the distance (in mm) travelled by the solvent was measured exactly from the horizontal line drawn up to where it was last seen when it moved up. The spots were also measured and for those samples that had 2 or more spots, each spots were measured individually. The equation used for solving the Rf value is: For accuracy, the distance travelled by the spot was measured from the horizontal line up to the center of the spot. Rf values were used to compare the substances and identify the analgesic compound present in an unknown sample. Similarities was observed between Aspirin and the unknown analgesic drug F since their spots are very similar and their Rf values are very close to each other with only a 0.004 mm difference. Also, the results show that the caffeine extracted from the experiment â€Å"Isolation of caffeine from tea leaves† is indeed caffeine since spot C or pure caffeine is very similar because the spot produced by the tea extract and this is evident since it is indicated in their Rf values that they are very similar to each other. In comparing compounds used in the experiment run, the group observed that compounds with the larger Rf are less polar because it interacts less strongly with the polar adsorbent on the TLC plate (Ault, 1998). The experiment went as expected with no unusual events that would have introduced error. The group was able to perform the thin-layer chromatography and to compute for the different Rf values. CONCLUSION Thin-layer chromatography (TLC) was the technique used to determine the composition of various over-the-counter analgesics and the purity of the different substances which were Aspirin, Ibuprofen, Caffeine, Paracetamol, tea sample from one of our previous experiment and an unknown sample. With thin-layer chromatography, it was identified that compounds with the larger Rf are less polar because it interacts less strongly with the polar adsorbent on the TLC plate, and compounds with a smaller Rf values are more polar. It was also observed that the tea sample gathered from one of our previous experiment was indeed pure caffeine because of the similarities of the spots and Rf values of the spot C and pure caffeine. The different analgesic drugs that were observed to have 2 or more spots were Aspirin, Ibuprofen, Paracetamol, the unknown substance and the co-spot. Two or more spots were observed because of impurities or it contains different substances. Lastly, the unknown sample in the TL C plate was observed to be Aspirin because of the similarities of the measurement of the spot and Rf values which only had a difference of 0.004 mm. RECOMMENDATIONS To obtain a better result of the experiment, the different techniques can be done. One technique that can be done is a volatile solvent like 25 parts ethyl acetate, 1 part ethanol, and 1 part acetic acid. The TLC plate is very sensitive to different materials or compounds and it is important not to touch the TLC plate to avoid contamination of oil from the hands. In collecting different sample, one should remember to wash capillary tube with dichloromethane not less than three times to avoid contamination. To place appropriate size of each spot so it won’t mix with the other spots. For light/dull colored samples, it is recommended to place spots up to three times for it to be visible. In preparing the chamber, one should moisten properly the filter paper to have equal rising of the solvent and cover all the times the chamber since the solvent is volatile. Lastly, drop properly making sure it falls in an upright postion or the TLC plate should lean to the filter paper and remem ber not move the chamber in any way to avoid unequal rising of the solvent to the TLC plate.
