Kundun essays
Kundun essays The sons of Genghis Khan have for many centuries chosen a Dalai Lama to rule over Tibet. The words Dalai Lama mean Ocean of Wisdom. He is the manifestation of the Buda Of Compassion. This is the true story of Tibets Dalai Lama. In 1933 the thirteenth Dalai Lama died. A holyman has been searching for the past four years for the next Dalai Lama. A young boy by the name of Lhamo plays at his farm home on the far outreaches of Tibet close to the border of India. He asks repeatedly for his mother to tell him about the day he was born. She tells him it was a terrible time and his father was sick. He was born at dawn and thats when his father got better. She also says there were a pair of crows nesting on the roof that day just like the Dalai Lama. A visitor comes to the farmhouse the next day. He has a necklace, and when Lhamo sees it he says that it is his. The man gives Lhamo the necklace but Lhamos mother makes him give it back to the visitor. Lhamo is sad when the visitor leaves for Lhasa. Lhamo says he has always wanted to go to Lhasa. Lhamo is awakened during the middle of the night and is lead into the living room. The visitor is back from Lhasa and has brought people and objects with him. He asks Lhamo to chose out of a pair of items which one is his. With each pair of items he chooses the item that belonged to the thirteenth Dalai Lama. The visitor and his company call him Kundun and bow before him. Two years later Kundun leaves his home accompanied by his older brother who is to teach him. He meets Palah, the Lord Chamberlain, and is told the story of the first Dalai Lama and the crows. At the monastery in Lhasa, Kundun overhears people talking about him and questioning why he was found so far out in the country. Kundun continues with his education and is taught what he cant eat or do. Its 1944 and Kundun explores a car, drives and crashes it. Kundun and his brother explore al...

Lead Reasearch essays
Lead Reasearch essays Electrochemical Equivalent: 3.865g/amp-hr Incompatibilities: Strong oxidizers, hydrogen peroxide, acids Valance Electron Potential (-eV): 24.2 Chemical reactions of the element lead The surface of metallic lead is protected by a thin layer of lead oxide, PbO. Only upon heating lead to 600-800C does lead react with oxygen in air to from lead oxide, PbO. Finely divided lead powder is a fire risk. The surface of metallic lead is protected by a thin layer of lead oxide, PbO. It does not react with water under normal conditions. Lead metal reacts vigorously with fluorine, F2, at room temperature and chlorine, Cl2, on warming to form the poisonous dihalides lead(II) fluoride, PbF2, and lead(II) chloride, PbCl2, respectively. The surface of metallic lead is protected by a thin layer of lead oxide, PbO. This renders the lead essentially insoluble in sulphuric acid, and so, in the past, a useful container of this acid. Lead reacts slowly with hydrochloric acid and nitric acid, HNO3. In the latter case, nitrogen oxides are formed together with lead(II) nitrate, Pb(NO3)2. Lead dissolves slowly in cold alkalis to form plumbites Boiling Point: 2013K 1740C 3164F Coefficient of lineal thermal expansion: Enthalpy of Atomization: 194.6 kJ/mole @ 25C Enthalpy of Vaporization: 179.4 kJ/mole Flammablity Class: Non-combustible solid (except as dust) Melting Point: 600.6K 327.6C 621.7F Pysical State (at 20C Vapor Pressure = 4.21E-07Pa@327.6C A. Ways in which lead enters the body Lead can be absorbed into the body by inhalation (breathing) and ingestion (eating). Lead is not absorbed through the skin. Inhalation of lead is considered the most important source of occupational exposure. When lead is scattered in the air as a dust or fume, it can be inhaled and absorbed through the lungs and upper respiratory tract. Lead can also enter the digestive system if...

Headspace Analysis Essay Example | Topics and Well Written Essays - 750 words
Headspace Analysis - Essay Example This technique has been used to identify spoiled food, fragrances from botanical material, the determination of plasticizers in plastics and for forensic samples involving arson snuff. Its main component, nicotine is habit forming and other compounds produced by pyrolysis during smoking are carcinogenic and can cause a number of other health problems. Tobacco is an extremely valuable export in the United States despite the health concern, and its quality is carefully monitored. Tobacco can be flue cured, air cured, fire cured or sun cured, but the quality of the product can often be monitored by analyzing the vapors in the head space above the tobacco. The head space over tobacco can be sampled and analyzed using a Solid Phase Micro Extraction (SPME) technique. Diesel is similar in chemical composition to kerosene and heating oil in that it is composed of aliphatic hydrocarbons that are obtained from the fractional distillation of crude oil. Diesel has a higher boiling point fraction and the distillation range is greater than that of kerosene and heating oil being composed of essentially C10 to C25 aliphatic hydrocarbons. The use of these extremely sensitive laboratory techniques must be made carefully because of the consequence of obtaining a false positive result. The possibility of the accidental contamination of a sample through poor sampling and laboratory techniques needs to be minimized. The research has shown the sample containers can be cleaned before use and should be sealed before transport to the fire scene. Samples should then be delivered to the laboratory and analysed promptly. The laboratory equipment should be cleaned before use and blank samples analysed regularly to check for any possible contamination. The extraction equipment can be cleaned by washing with acetone and heating the gas transfer lines with a Bunsen burner. The interpretation of the chromatograms must be made carefully using a library of chromatograms composed of the common accelerants, industrial solvents, common household materials, The analysis of numerous burnt synthetic materials was found to be distinct from the common accelerants. The common accelerants were found to change during evaporation making it sometimes difficult to distinguish between those composed entirely of entirely of an aliphatic hydrocarbon fraction. Ethanol could not be detected in fire debris using charcoal absorption extraction techniques and alternative analytical techniques were needed. The background level of accelerants in the environment is dependent of the history of the sample material. Traces of petrol and aliphatic hydrocarbons were found in soil from a motor wrecking yard, however, no traces were found in numerous car flooring materials indicating none would be expected from a domestic environment. Gas odourants could also be detected using the same equipment as that used for fie debris analysis which would assist the investigation of suspected gas explosions. References: 1. Evans, J.S.

Direct Digital Synthesis Research Paper Example | Topics and Well Written Essays - 1500 words
Direct Digital Synthesis - Research Paper Example Direct digital synthesis is about storing waveform data points in digital format, and then recreating them with the use of digital to analog converters from the stored data. Essentially, the speed with which the synthesizer is able to regenerate the waveform is correlated with the waveform frequency. Digital techniques for mapping waveform data point into digital formats for storage and retrieval and are at the heart of DDS systems. In essence the basic components of a DDS system are the phase accumulator, the waveform map, the digital to analog converter or DAC, and the low pass filter, which sums up the DDS process from the mapping of the waveform signal into digital data, to the recreation of the analog waveform via the use of a DAC and a low pass filter to perfect the waveform. The illustration below details this simplified DDS system [1]: An even more simplified version of the DDS architecture shrinks it into two essential components, the phase generator/accumulator, which is time discrete, and the phase-to-waveform converter, for recreating the appropriate output signal of the DDS [2]: In the image above, the low pass filters and the waveform map that is part of the previous diagram are assumed to be present in the background, as peripheral components [1] [2]. On the other extreme is a more detailed diagram representing the basic functions of a DDS system, that expands on the first diagram above, and includes the waveform map and low pass filter [3]: The idea behind DDS is that waveforms of various kinds are easily implementable and can be easily recreated from digitally stored waveform data, and the freedom that this gives to designers includes that whereas in the past, more and more complex analog components were needed to recreate more and more complex waveforms, in the case of DDS systems all that is needed is stored digital data.Ã

Why did Britain and France get out of Africa between 1957-1965 Essay
Why did Britain and France get out of Africa between 1957-1965 - Essay Example 56). They, therefore, had to redirect most of their finances in rebuilding their cities; hence, they could not afford to sustain the manpower they had deployed to run the colonies. From an economical point of view, the colonies did not generate enough income to sustain themselves; therefore, it was uneconomical for the two countries to retain them. Secondly the rise of nationalism and nationalists helped to speed up the evacuation process. Countries like Ghana, found in West Africa had extremely powerful nationalists who fought for the liberation of their country, for example, Kwame Nkurumah. Among his achievements, he helped to unite African countries through the establishment of Pan-African Union. Nationalists from different countries were able to meet during these forums, whereby they discussed their grievances and formulated plans to forcefully evict their oppressors. The liberated countries also provided military support to other African countries which opted to evict their colonial masters. However, these countries only resorted to the use of violence because peaceful negotiations had failed (Mungazi 1996, p. 113). Thirdly, international pressure from other countries, which did not have colonial possessions also helped to speed up the evacuation process. the formation of United Nations after the second World War united most countries and brought about the rise of the veto states. These states had the final say in most things affecting the United Nations. Among these countries was the USA, which used, to be Britainââ¬â¢s colonial possession before gaining independence in 1776. This would explain why USA was a forerunner in the fight against colonialism. Britain and France faced a lot of opposition from USA which lobbied the support of China and Russia when making veto decisions. This constant opposition affected France and Britain and undercut their advancement

Two Types Of Therapies Essay -- essays research papers
There are many different types of therapies or psychological methods used to alleviate problems. First, there are therapies that emphasize the value of gaining insight to personal problems. Then there are behavior therapies and cognitive therapies, which are used to directly change troublesome actions and thoughts. Two therapies I will be describing are rational-emotive behavior therapy and psychoanalysis. à à à à à According to author Dennis Coon of Introduction to Psychology, ââ¬Å"Rational-emotive behavior therapy (REBT) attempts to change or remove irrational beliefs that cause emotional problems.â⬠Albert Ellis states the basic idea of rational-emotive behavior is easy as ABC. He assumes that people become unhappy and develop self-defeating habits because they have unrealistic or faulty beliefs. à à à à à Ellis analyzes problems in this way: The letter A stands for an activating experience, which the person assumes to be the cause of C, an emotional consequence. For example, a person who is rejected (the activating experience) feels depressed, threatened, or hurt (the consequence). Rational-emotive therapy, however, shows that the real problem comes between A and C. In between is B, the patientââ¬â¢s unrealistic beliefs. à à à à à There are many irrational or unrealistic beliefs that we all tend to hold. For instance, certain people I must deal with are thoroughly bad and should be severely blamed and punished for. Thi...
