How to Make Pure Sand

How to Make Pure Sand Sand that you find on a beach or a playground is a mixture of minerals and organic matter. Pure sand, which is silicon dioxide or silica, is a chemical you may not encounter. However, you can make pure sand yourself quite easily: Ingredients for Sand sodium silicate (make it yourself)sodium bisulfatewater Make Sand Mix together 5 ml sodium silicate solution and 5 ml water.In a separate container, stir 3.5 grams sodium bisulfate into 10 mL of water. Keep stirring until the sodium bisulfate dissolves.Mix the two solutions together. The resulting gel that forms at the bottom of the liquid is orthosilicic acid.Place the orthosilicic acid into a heat-safe glass or porcelain dish and heat it over a burner flame for about 5 minutes. The orthosilicic acid dries to form silicon dioxide, SiO2, which is your sand. Sand is non-toxic, but it presents an inhalation hazard since the small particles could become trapped in your lungs if inhaled. Therefore, enjoy your sand, but dont play with it like you might with natural sand. White Sand Beach

The Russian Revolution Essay Example | Topics and Well Written Essays - 750 words

The Russian Revolution - Essay Example Why did the revolution occur and what was the result? This is what this paper is going to focus on. The kind of revolution envisaged by Marx and Engels was to be as a result of workers consciousness or bourgeois intelligentsia. In many countries workers started forming trade unions to fight against employers and the government so as to pass labor legislations that improve their conditions. However, for Beeler and Clark the Russian revolution was â€Å"a natural and inevitable outcome of development of ideas among revolutionary socialist intelligentsia.†1 For them, socialist movements such as the trade unions are not enough to get the kind of social democracy needed otherwise the proletariats attempts would fail just like the first revolution that removed tsar from office did not work. The mistake that socialists such as Alexander Kensky made after seizing power in Russia was failure to confiscate large landholdings and give it to peasants who had fought hard to free themselves from exploitation.2 These leaders were not intelligent enough to lead a revolution like Lenin. In other words, Beeler and Clark would say they lacked revolutionary professionalism thus not revolutionary social democrats. ... The food shortage experienced in 1917 due to the war led to violent street demonstrations and an unplanned uprising occurred and in March 12, 1917 the Duma took over leadership and declared a provisional government.3 This government emphasized equality before the law, freedom of religion, speech and assembly as well as the rights of unions to organize and strike but it shared power with Petrograd soviet of workers and soldiers leading to a state of anarchy.4 The government was also unable to remove Russia from the war thus giving an opportunity to Lenin to wage his campaigns and attract huge masses of people. The provisional government rule was not successful since the leaders lacked leadership skills. For a revolution to be successful it has to be led by professional revolutionaries and not trade unionists or socialist intellectuals. It needs radical revolutionary leaders like Lenin and Trotsky who are always preoccupied with social democratic activities. Lenin called for â€Å"dis ciplined workers who are controlled by small, dedicated elite of intellectual and professional revolutionaries† as opposed to masses.5 The group was referred as Bolsheviks and though they failed in their first attempt to seize power from the provisional government, the army skills of Trotsky and support of soldiers and workers tired of the war made the second attempt to be successful. The Bolshevik majority declared all power for the soviets and Lenin as head of government thus displacing the provisional government.6 However, to end the war he had to sign the Treaty of Brest-Litorsk thus ceding Russian territories to central powers. Civil war ensued thereafter but the

Explanatory synthesis - Essay Example Social psychology challenges the most basic assumptions of human behaviour and nature, and to a big extent the predictability of the social world. Psychologists look at the different kinds of situations in the world in a very distinct and different way from that of other people and they apply the beliefs and insights of psychology to the unfolding social events around them. Individuals respond differently to social influences by either choosing to comply, identifying, complying or internalizing. Compliance is seen as a form of agreement to the particular situation at hand, but deep from within the person might be in no way convinced. Situations in a big way determine the kind response a person will extend to particular situation. In the text, Ross argues that the type of information about personality that most of the people would possess before predicting personality proves to be of relatively little value. Research has indicated that when faced in certain situations such as these, i t is not possible to predict with accuracy how particular people will respond. Situational behaviour in relation to an individual’s actions can be demonstrated in the parable of the Good Samaritan. The story is about a Jewish man who was travelling to Jericho, but bandits attacked him and left him lying half-dead by the roadside. A priest passes him and offers him no help, until a Good Samaritan whose stereotype hated the Jews stopped by and offered the man assistance. The study experimenters of social philosophy recruited 67 students from the Princeton Theological Seminary, telling them that it a study about religious education and vocations (Hoyk, Hersey 49). Unknown to these participants, they were to be subjected to their own personal Good Samaritan attributes. The requirement was that they would fill questionnaires on their personality then walk to a nearby room to give their talk. On the doorway, a man was lying doubled over with his eyes closed and coughing. All the pa rticipants would not escape the site of the distressed man and the biggest question was, would they be willing to offer any assistance to the man? In their assumption, the experimenters thought that it would be dependent on how much the participants were hurried, and thus devised a way of manipulating them, by giving each a map and one of the instructions which either stated that the participant was late and had been a few minutes late. Another stated that the assistance was waiting for the participant, yet the other stated that it would take another few minutes before the interviewers were ready, but had the option of proceeding over. This created conditions of high, medium, and low hurry and thus some students left the office thinking that they needed to be quick, others less while the rest felt relaxed. Each of the three conditions were was also divided into two, half of them were required to give a talk on the Good Samaritan and the other half on prospects for seminary graduates . This helped the experimenters to assess both the effects of hurry and the talk they were to give on students’ helping behaviours. The outcome of the experience was classified into two classes, which included in a hurry and could not stop and judge on context. From the results, only 40% of the students offered some form of assistance to the people, with a few stepping over the apparently injured man, but it was evident that the amount of hurry they were in had a

Airport Incident Management System Essay Example for Free

Airport Incident Management System Essay 1. Introduction Airport operations are growing in complexity day by day, and extend across multiple service providers at the airport – namely ground handlers, customs, immigration, retail tenants, air traffic control, security, baggage handlers, airlines consortiums and airlines. These agencies use the airport infrastructure in such a way that they meet their commitment to their customers in due time. These commitments put a lot of pressure on the airport infrastructure support staff to keep the systems up and running efficiently. Currently these services are handled manually at most of the Indian airports, so there are umpteen chances of these services to breakdown at most appropriate time when airport are supposed to meet their stated commitments with agencies. These incidents are very frequently occurring, particularly at the busy airports like Delhi and Hyderabad where pressure to meet timelines are heavy on airport infrastructure. Therefore there is a need for a technology solution to provide the flexible and proactive service delivery which guarantees the availability and usability of the infrastructure available at the airport to meet the commitments. This case study discusses a solution that raises the service level of the airport to its agencies and eventually creates a positive image in the minds of its users. This case study is based on this technical solution provided at one of the busy airport where the technical solution created, provides the right answer to different stakeholders at the airport. The context diagram [pic] Source Internet 2. Case Study Purpose The purpose of this case study is to highlight the technical solution provided to solve the problems arising due to the multiple agencies of the airport using the same airport infrastructure. 3. Case Study Methodology The methodology to arrive at the solution to the use of airport infrastructure problem was the extensive survey method and later on the software implementation methodology for implementing AR Systems (Incident Management Components). The Survey Method A questionnaire about the status of services provided by the current staff to the concerned agency department was circulated and feedback collected. The response feedback was consolidated and improvements discussed and applied. A need to streamlining the procedure or writing the standard procedure was felt and implemented in the short run. Visits by senior management staff to similar airport and studying the response to the tender floated by the airport led to the long term planning of implementing the software solution. 4. The technology strategy After the gruesome struggle to provide the required service 247 at the airport terminal building, a search for better technical solution that can cater to the current requirement and as well as give scope for future growth is always on. A team of experts were constituted to suggest the course of action which can address the airports infrastructure problem in the short run and simultaneously can find appropriate technology solutions to mitigate the problem as well as expand the extent of service at the airport for future projections. Short Term Planning – It was felt that in short run the airport operation must have the standard procedure which can be followed and improved with the experience of supporting the agencies of the airport. The performance of the support staff can also be measured and their skill enhanced to meet requirements of different support levels. Long term Planning – An appropriate IT solution must be developed or procured to record incidents / solutions and can use the learning/Knowledge for handling future incidents.

General Agreement on Tariffs and Trade in E-Commerce Essay -- Trade Ec

General Agreement on Tariffs and Trade in E-Commerce The US is seeking to extend the duty-free status of international online transactions to protect the development of global electronic commerce, the Clinton administration said yesterday. Susan Esserman, deputy US trade representative, said the US wanted the World Trade Organization to agree "at the earliest possible date" to extend the current moratorium on customs duties for electronic trade. In testimony to the Senate foreign relations sub-committee on Europe, Ms Esserman said duty-free cyberspace was particularly valuable to US software companies that were seeking to distribute their products electronically. The US is also looking for WTO members to affirm that electronic commerce is subject to existing rules and agreements, and should not face "unnecessary regulatory barriers to trade". However Ms Esserman said "more time and work are necessary" before electronic goods could be subject to final classification under WTO rules. Electronic commerce in the US is forecast to grow to $1,300bn by 2003, while in India it is expected to grow by $15bn within two years. Richard Wolffe, Washington Protectionism, it seems, is always with us and it is useful to examine the intermittent attempts made to establish rules for its containment. This book is one such examination, on the conception, birth, and early years of the General Agreement on Tariffs and Trade (GATT); it is restricted to the years 1940--53. It is the work of an historian but one at the political, rather than economic, end of the spectrum. The heavy emphasis throughout is on the American role within an essentially Anglo-American tussle. The argument is that although trade was a relatively small proportion of US output it was used for political and diplomatic purposes. The general thrust is that the US was keen on a new liberal order and determined to break the British empire's preferential trading arrangements. However, when we read that the central argument is that, 'by liberalizing trade while protecting domestic economies -- a bargain consistent with US trade law, practice, and history ...', we might reasonably expect to be in for a roc ky ride. Politics is important and possibly even central in the process of trade protection, but will always be found to depend on economic forces.

The cheapest way for the Japanese to meet their paper needs has been to import raw logs from America, a trade which ended in the 1980s because there simply was not enough timber to supply Japan and satisfy domestic U.S. needs. Free trade, of course, demands that traders sell to the customer who offers the highest price; they cannot be required to fill the needs of one market at the expense of another. Should Americans sell to Japan at higher prices even if it means domestic shortages, or is it appropriate to say, "These are our trees, hands off"? The arguments that apply to protecting timber can also be easily applied to other natural resources, such as coal or copper. On the other hand, free trade agreements work to the benefit of the United States in terms of resources where we cannot fill our own needs, such as oil or gold. Although each of these arenas has its own specific issues, in each case the essential question boils down to: "Is this important enough to our country that we should protect ourselves against the inroads of foreign traders, thereby cutting ourselves off from the benefits of free trade?"

Gonzales V. Raich

Pace University Michael Khoo LAW 101 Gonzales v. Raich(545 U. S. 1 (U. S. Sup. Ct. 2005)) I. FACTS Angel Raich and Diane Monson (plaintiffs) suffered from serious medical conditions and the only effective treatment was the use of Marijuana which was recommended by the doctors. In 1996, a California statue, under the name of The Compassionate Use Act, was established to legally allow marijuana to be used only for medicinal purposes. Monson cultivated her own Marijuana for her own usage as she relied on it heavily for daily functions.The Drug Enforcement Administration (defendant) came to Monson’s house, discovered the cannabis plants and destroyed all six of them. Raich and Monson sued the DEA to obtain an injunction that would inhibit the enforcement of the federal Control Substance Act (CSA) on Monson. The CSA classifies marijuana as a controlled substance. Raich and Monson claimed that enforcing the CSA would violate the Commerce Clause and the Due Process Clause of the Fift h Amendment. II. JUDGEMENT Angel Raich and Diane Monson (plaintiffs) won the case.The Drug Enforcement Administration (defendant) lost the case. III. LEGAL PRINCIPAL A. ISSUE Whether Congress’ power to regulate interstate markets for medical substances encompasses the portions of those markets that are supplied with drugs produced and consumed locally. B. HOLDING No. IV. REASONING A. GENERAL ANALYSIS In this Constitutional Case, the Controlled Substance Act (CSA) gives Congress and the Federal government the right to confiscate and/ or destroy any discovered controlled substances.Marijuana is considered a schedule 1 controlled substance due to hazards, high potential for abuse and lack of medicinal benefits. The Compassionate Use Act was created in 1996 in California as a statue that legally allows Marijuana to be used only for medicinal and medical purposes. The argument used against the DEA for enforcing the CSA on the plaintiffs is that it would be a violation of the Comme rce Clause which is a major component of the Fifth Amendment.The Commerce Clause establishes that the congress has the authority to oversee, regulate and intervene in interstate commercial activity. B. APPLIED ANALYSIS The Controlled Substance Act’s jurisdiction was used by the DEA to destroy Marijuana in Monson’s house because of the simple fact that Marijuana is categorized as a Schedule 1 controlled substance. However the plaintiffs argue that such action would take away the power of the Commerce Clause of the Fifth Amendment which states that the federal government body has the authority to overlook and regulate interstate activity.Nowhere in that clause does it give the federal body the power to regulate intrastate activity which is the case of the cultivation of marijuana in Monson’s house. In addition to that, the Compassionate Use Act supports the cultivation of marijuana in Monson’s house because Monson is a patient who was severely ill and whose life was dependent on the usage of Marijuana for recovery. According to the circumstances of this case in which the possession of marijuana was due to health, medical and medicinal reason, and for abuse purposes, the Supreme Court has overruled the DEA to execute the CSA on Monson.

Police Operations Paper Jessica Eley Todd Larson CJA/214 9/6/11 In the early 1900 policing made up of two basic functions patrolling and investigating crimes.

In policing there are applications†¦show more content†¦Police workers experience various tasks, interpersonal and physical demands during police operations that the majority of ordinary people never come across at their work or in their families. These requirements and stressors negatively influence a physical and psychological condition that ma y lead to more serious physical or mental damage or interruption role and physical demands for policemen can develop a condition of constant overload called hyper stress. Typically, the number of queries concerns and emergency calls exceeds the time assigned to a particular police worker. Therefore, not only is the quality of the time given to each separate case and that’s why each case at risk, the mental and physical condition of the police worker is in jeopardy. Regarding investigators, they experience heavy caseloads for which they are expected to follow prescribed case management criteria. Also, they find themselves within very limited time framework set by prosecutors who may keep them under the pressure to finish the process as fast as they possibly can, so that the case can reach the trial. Insomnia or permanent tiredness is often caused by hyper stress, as well as weight loss /gain and different degrees of impairment of mental processes.
