- 18131: China And Japan
- ... lands by re-settling villages and expanding water supply like the re-opening of the Grand Canal in 1415. Silk and cotton dominated the local markets. Silver was a dominate market in the mid 1600’s. It was imported from mines in Western Japan. Spanish Galleons brought Peruvian silver into China. This led to the opening of the private “Shensi Bank” branches to accommodate the transfer of funds. Rather than paying ... and are know as the Ch’ing Dynasty or Manchu. They ran the same style of government as Ming. In the late 16th century, Ch’ing took over south China with the help of Ming’s generals that allied with Ch’ing after the collapse and moved the capital from Mukden to Peking. Manchu appointed two people, one Manchu, and one Chinese, to each key post in the central government. It ... strongest countries of their time. They were the strongest countries in international trade. They would stop growing in the late 19th century due to lack of technology at that time. Japan had two different eras’s from 1500 to 1800.

- 18132: Causes Of The American Civil W
- ... were a few important factors that helped to increase tensions in both the North and the South. Some of these factors were the Anti-Slavery movement, Kansas-Nebraska Act, the Fugitive Slave Law, John Brown’s raid at Harpers Ferry, Uncle Tom’s Cabin, and the election of Abraham Lincoln into Presidency. There were quite a few events that caused tensions in the North. The anti-slavery movement greatly influenced the north’s feelings toward slavery. Writers like William Lloyd Garrison, Frederick Douglass, and Harriet Beecher Stowe wrote on the topic of slavery and helped lead the movement against it. In his newspaper, The Liberator, William Lloyd ...
- 18133: Green Fluorescent Protein Purification
- ... 27-30 kD) green light bulb that can be tacked on to other proteins at either the N- or C-terminus without a distortion of its compact beta-can structure. Biochemists now frequently exploit GFP’s unique structural and physical characteristics to visualize various cellular activities. One such application of GFP is to understand the role of a hormone, T3, in the translocation of thyroid hormone nuclear receptors (TRs).* In this project, GFP was fused to the human TR subtype b1 protein and the protein’s intracellular movement was visually tracked in live cells in the presence or absence of the T3 hormone. The prevalent hypothesis of this experiment was that T3 is essential in directing TR proteins to the nucleus of the cell where the proteins bind to DNA, regulating thyroid activity. GFP was fused to the amino terminal because that region is not involved in TRb1’s hormone and transcriptional activity whereas the COOH-terminal region is essential to this protein’s activities. In vitro studies showed that the addition of GFP to TRb1 did not affect TRb1’s ability to ...
- 18134: She Walks With Beauty
- Explication of Lord Byron’s "She Walks In Beauty" Lord George Gordon Noel Byron, or Lord Byron as he preferred to be called, was a known philanderer with an insatiable appetite. In letters to Percy Shelley, he told of short ... the woman than the wording of the poem. The alternating rhyme scheme in all three sestets gives the poem its consistent tone. "She walks in beauty, like the night," (1) rhyming with "And all that’s best of dark and bright," (3) makes the poem easier to remember and pleasing to the reader’s eyes and ears. The iambic tetrameter, when read aloud, guides the reader along in such a way that the poem maintains a smooth and graceful sound. "Of cloudless climes and starry skies," (2) is ...
- 18135: Constructing Settlement Patter
- Looking at the ethnohistoric sources of the Crow Indians can help construct the settlement and subsistence patterns of the prehistoric counterparts of the Crow. According to one source, Joseph Medicine Crow's book From the Heart of the Crow Country, the reader is informed that when the Absarokee separated from the main tribe, believed to be the Hidatsa, they abandoned the ways of agriculture and went back ... the family, with the clan being the secondary unit. The clan is made up of distantly related families with membership based on matrilineal descent. This mens that a person belongs to his or her mother's clan, not the father's clan. Then as the tribe population increased, it divided into sub-tribes or bands for the convenience and travel. These bands were governed by band chiefs which were supported and advised by a body ...
- 18136: Comets
- ... The coma, also called the head, is a dense cloud of water, carbon dioxide and other gases and comes off of the nucleus. They can be several thousand kilometers in diameter, depending on the comet’s distance from the sun and the size of the nucleus. The size of the nucleus is important because since large nuclei have a greater surface area facing the sun, which is the side that is ... distance the particles that drift out from the sun act as a powerful wind which blows the gas and dust particles away from the nucleus and coma. This is the process which makes the comet’s tail. The hydrogen cloud is very large at millions of kilometers in diameter. But it is only a very sparse body of neutral hydrogen. It was discovered from spectroscopy that was carried out by satellites ... This cloud remains a theory only, as it has never been directly detected. The Kuiper Belt is a region that was first proposed by the Dutch-American astronomer Gerard Kuiper in 1951. Seeing that Oort's cloud of comets did not really explain the reason for the population of comets with short orbital periods (making complete orbits around the sun in less than 200 years), Kuiper thought that a belt ...
- 18137: Saturn
- Saturn Saturn is one of the largest and most beautiful planets in the star system. Saturn is the second largest planet in the solar system second to only Jupiter. Saturn's many rings give the planet it's beauty along with its dark orange and red color. Saturn is much like Jupiter they are both gaseous planets with small rocky cores but Saturn is far less dense than Jupiter in fact its the least dense planet in the solar system. It's density is only 0.69 g/cm making it less than water. If Saturn was put in water it would float. Saturn is 764 times larger than earth and 96 times more massive. Saturn ...
- 18138: Contributions Of Ancient Egypt
- Contributions of ancient egypt Many of ancient Egypt's contribution to society not only advanced them as a civilization but left an impressionable impact on the accomplishments of the modern day. Nestled within the fertile valley of the Nile, Egypt was protected on all ... invasion and at the same time uninfluenced by many outside cultures. Although its overall isolation by the expanse of the surrounding desert to the west and the red sea to the east, this thriving culture's achievements went beyond the imagination of even the most seemingly advanced world. This allowed the Egyptians to not only live peacefully and without an active army but also provided them with the security and time ... abundance of the Papyrus reed this natural resource was exactly that. The Papyrus reed, also known as the symbol for lower Egypt, could be rolled into scrolls, and stored safely to keep all of Egypt's official business on record as well as many of their intellectual secrets. Once the Egyptians established a way to record their work they were able to document the elements of their second greatest accomplishment, ...
- 18139: Clean Coal Technologies
- ... only is coal inherently impure by composition by the fact that it contains ash and sulfur; coal is also difficult to burn completely. Many techniques to combust coal have been developed since the late 1800's. "The first innovation were more concerned with achieving more complete combustion and reducing manual labor than they were with pollution and economic" (Ruzie 1) The history of coal can be dated back around 400 million ... into coal" (Hertz 1) There are many types of coal, including anthracite, bituminous, sub-bituminous, and lignite. Anthracite has the highest carbon content, anywhere from 86 to 98 percent. And produces nearly 15,000 Btu's per pound (British Thermal Unit, is the amount of heat needed to raise the temperature of the pound of water one degree Fahrenheit) (Bartow 1) The second type of coal is Bituminous or soft coal. It's the most plentiful type of coal in the States, and is mainly found in the eastern and middle part of the North American continent. Bituminous coal is primary used to generate electricity, and has ...
- 18140: Satellites
- ... in orbit by little pushes given by things called thrusters. Without these thrusters, 1 degree off coarse and the rocket could plummet to the earth and be destroyed by either burning up in the earth's atmosphere or crashing. Isaac Newton mentioned the possibility of making an satellite on Earth in 1687. Only in the early 20th century did the theory work. The Russian scientist Konstantin Tsiolkovsky and the experimental work ... the Committee for the International Geophysical Year (IGY), announced to other countries that they were considering launching small satellite vehicles for space exploration. In April and again in July 1955 the USSR and the U.S. announced plans to launch satellites for the IGY. The USSR launched SPUTNIK 1 on Oct. 4, 1957, and the United States launched EXPLORER 1 on Jan. 31, 1958. These two satellites provided a lot of ... the characteristics of the new space environment and for the design of communications, weather, and navigation satellites and eventually for manned space flight. Experimental satellites for all kinds of satellites quickly followed. Since 1957 thousand's of satellites have been placed in orbit, and satellites are now an accepted part of daily life. The United States and the USSR built the majority of these satellites. The European Space Agency is ...
