- 3751: Aleksandr Solzhenitsyn Russian Dissident
- ... Russian Revolution. He said that during his childhood he "bore this social tension - on one hand, they used to tell me everything at home, and on the other, they used to work our minds at school. And so this collision between two worlds gave birth to such social tension inside me that somehow defined the path I was to follow for the rest of my life." Aleksandr had little literary education and read few western novels, and later said he regretted it (Major 20TH Century Writers, p 2792-2793). *After grade school Aleksandr went to the University of Rostov-on-Don and graduated in 1941, majoring in mathematics and physics (Encarta 99). After he graduated, he served as a captain of artillery in World War II from ... The Encyclopedia Americana, p 210). * After he was released from a concentration camp in Ekibastuz, Kazakasthan, Aleksandr went into exile in Kok-Terek in Central Asia, where he taught mathematics and physics in a secondary school (Major 20TH Century Writers, p 2793). Since he was out of prison, he now could write without anyone knowing. He wrote a long poem, and some plays. Aleksandr also began to make notes for ...
- 3752: Pre-Civil War New Orleans
- ... known as the Crescent City. New Orleans, with a population of 496,938 (1990 census), is the largest city in Louisiana and one of the principal cities of the South. It was established on the high ground nearest the mouth of the Mississippi, which is 177 km (110 mi) downstream. Elevations range from 3.65 m (12 ft) above sea level to 2 m (6.5 ft) below; as a result ... on their cargoes from those areas of West Africa with significant Muslim population. As the Islamic belief system forbids suicide and encourages patient perseverance, the middle-passage survival rate of captured African Muslims was quite high. For example, one such courageous survivor was Ibrahima Abdur Rahman, son of the king of the Fulani people of the Senegambia region, named "The Prince" by his master Thomas Foster of Natchez, Mississippi. Abdur Rahman ... who also usually freed the mother of their children. It would be several generations before mulatto, quadroon, and octoroon women would become the common-law wives and mistresses of white men. The reason for the high number of f.p.c. in New Orleans was largely due to the influx of Haitian Refugees into the city in 1809. Approximately 10,000 people arrived in New Orleans with roughly a third ...
- 3753: Was Colonial Culture Uniquely
- ... unique culture for that colony. And while each colony had it's share of groups, the mix of people and their cultures in each colony was not evenly distributed. In some colonies there was a high mix of people, while in others one group dominated. These regional differences caused the colonies not to develop one unique culture, but instead a group of distinctive cultures, each unique, and each regional. The regional ... took advantage of the long growing season and tobacco became the number one crop (Brinkley, 1995). Society of the southern colonies most closely resembled that of aristocratic England. Plantations contained a virtual monarchy, each with school, a church, and servants (Brinkley, 1995). Many Virginians sent there children to be schooled in England (Brinkley, 1995). To the west was the frontier and a wholly different set of conditions. The environment consisted of ...
- 3754: Oxygen
- ... by the Swedish chemist Carl Wilhelm Scheele; it was shown to be an elemental gas by the French chemist Antoine Laurent Lavoisier in his classic experiments on combustion. Large amounts of oxygen are used in high-temperature welding torches, in which a mixture of oxygen and another gas produces a flame of much higher temperature than is obtained by burning gases in air. Oxygen is administered to patients whose breathing is impaired and also to people in aircraft flying at high altitudes, where the poor oxygen concentration cannot support normal respiration. Oxygen-enriched air is used in open-hearth furnaces for steel manufacture. Most of the oxygen produced in the United States is used to make a mixture of carbon monoxide and hydrogen called synthesis gas, used for the synthesis of methanol and ammonia. High-purity oxygen is used also in the metal- fabrication industries; in liquid form it is of great importance as a propellant for guided missiles and rockets2. I have chosen the element "Oxygen" because without ...
- 3755: Solar Cells
- ... this, electrons in the valence band can easily be made to jump to the conduction band by the injection of energy, either in the form of heat or light [Book 4]. This explains why the high resistivity of semiconductors decreases as the temperature is raised or the material illuminated. The excitation of valence electrons to the conduction band is best accomplished when the semiconductor is in the crystalline state, i.e. when the atoms are arranged in a precise geometrical formation or "lattice". At room temperature and low illumination, pure or so-called "intrinsic" semiconductors have a high resistivity. But the resistivity can be greatly reduced by "doping", i.e. introducing a very small amount of impurity, of the order of one in a million atoms. There are 2 kinds of dopant. Those ... radiation of a particular spectral composition is directly proportional to the irradiance [Book 2]. Some types of solar cell, however, do not exhibit this linear relationship. The silicon solar cell has many advantages such as high reliability, photovoltaic power plants can be put up easily and quickly, photovoltaic power plants are quite modular and can respond to sudden changes in solar input which occur when clouds pass by. However there ...
- 3756: Accountants
- ... is done. Class: Accountants Special Interest: Analyzing Financial Information Subclasses: Financial accountants Tax accountants Internal auditors A college student decides she wants to become an accountant. General accounting and bookkeeping classes can be taken in high school. In college, the student needs to decide on a more specific field of accounting. An accountant has many choices as to what particular field of accounting to specialize in depending on the financial information she ...
- 3757: Lab Protocols
- ... trial and error my class and I have learned that screwing around and misbehaveing in lab not only results in multiple page papers, but can also be harmful, dangerous, and costly to our teacher and school. There are many rules or "protocols" that should be followed in a lab enviroment. In this situation there are ten basic rules that must be followed at all times while participating in lab experiments. These ... Because you don't need to. The seventh rule states that activities should only be done if they are specifically discussed in your lab. This is for safety purposes and for the liability of the school. The eighth rule is that you are not to contaminate chemicals by using equipment in more than one substance without washing it thoroughly. Doing this can cause explosion, fire, bodily harm, poisonous gasses, or possibly ... result in death, poisonous gasses, bodily harm , explosion , or fire. Last but not least the tenth rule is that before taking leave of the laboratory environment set forth by the laboratory director and our prestigous school. You should thoroughly clean to your best ability the above stated area. This is to prevent possible chemical burns, toxic gasses, highly flammable substances, and acids from forming on countertops. It also helps to ...
- 3758: A Dream Deferred - Poetry Explination
- ... Joplin, Missouri, James Langston Hughes (1902-1967) was born into an abolitionist family. As the grandson of James Mercer Langston, the first Black American to be elected to public office in 1855, Hughes attended Central High School in Cleveland, Ohio, but began writing poetry in the eighth grade, and was selected as Class Poet. His father didn't think he would be able to make a living at writing, and encouraged him ...
- 3759: Radioactive Wastes
- ... large number of batch operations in series. Column operations become more practical. In many waste solutions, the radioactive ions are cations and a single column or series of columns of cation exchanger will provide decontamination. High capacity organic resins are often used because of their good flow rate and rapid rate of exchange. Monobed or mixed bed columns contain cation and anion exchangers in the same vessel. Synthetic organic resins, of ... evaporate off the bulk of the waste to obtain a small concentrated volume. The aim is to develop more efficient types of evaporators. At the same time the decontamination factors obtained in evaporation must be high to ensure that the activity of the condensate is negligible, though there remains the problem of accidental dispersion. Much effort is current in many countries on the establishment of the ultimate disposal methods. These are ... the absorbtion of montmorillonite clay' which is comprised of natural clays that have a good capacity for chemical exchange of cations and can store radioactive wastes, 'fused salt calcination' which will neutralize the wastes and 'high temperature processing'. Even though man has made many breakthroughs in the processing, storage and disintegration of radioactive wastes, there is still much work ahead to render the wastes absolutely harmless.
- 3760: Aristotles Life
- ... in Stagira, and both of his parents died when he was a boy. His legal guardian named Proxenus raised him (World Book 663). At the age of 18 years of age, Aristotle entered Plato s school in Athens called the Academy. When Plato died in 347 BC, Aristotle left the Academy to live with some of Plato s disciples who were living with Hermeias. In 334 BC, he returned to Athens and founded a school called the Lyceum (World Book 663). His school, philosophy, and his followers were called peripatetic, which is Greek for walking. The reason for this name was because Aristotle did most of his teaching while he was walking with his students. After Alexander ...
