Charles Charles Eastman was a young Dokota physician who went to Dartmouth College and Boston University. In 1890 he moved his practice as a physician to the Pine Ridge reservation in western South Dakota. His was part of Wahpenton and Mdewakanton Dakota tribe rather than Oglala Lakota and took pride in being Native. Upon his arrival‚ he experienced a disastourous dust storm and later would come across the aftermath of a massacre. The massacre was due to altercations of warfare on the northern

GREAT DISCOVERIES CHANGE LIVES Do you like watching television? I love it. I do not know what would I do if televisions did not exist. It is interesting‚ in several years‚ they have become a huge part of our lives‚ our indispensables. J.J. Thomson was inspired by some scientists and he provided us the opportunity of having televisions in our lives. Also other scientists improved his thoughts and experiments which leaded to the invention of the television afterwards. It is not that simple of course

conscious or unconscious. Still‚ most paintings tend to be similar enough to others in theme or composition that they lend themselves well to being compared and contrasted. I will compare and contrast George Tooker’s The Subway‚ and Cyril E. Power’s The Tube Train. George Tooker’s The Subway is a haunting yet beautiful piece. Painted using the egg tempera method‚ it is stunning for its strategic usage of warm colors. The intention of Tooker’s painting is to portray such a familiar scene as a subway as

Dengue fever can be caused by any one of four types of dengue virus: DEN-1‚ DEN-2‚ DEN-3‚ and DEN-4. You can be infected by at least two‚ if not all four types at different times during your lifetime‚ but only once by the same type. You can get dengue virus infections from the bite of an infected Aedes mosquito. Mosquitoes become infected when they bite infected humans‚ and later transmit infection to other people they bite. Two main species of mosquito‚ Aedes aegypti and Aedes albopictus‚ have

The chloride shift is basically an exchange of chloride ions through the capillaries of the system circuit. In the blood plasma‚ there is large amount of carbonic acid and when there is an increase in carbonic acid than the balance of hydrogen ions and carbonate ions dissociate to maintain a balance of homeostasis in the pH of the blood. The red blood cells help to maintain this system by buffering the system of carbonic acid and causing detachment of the above ions. The release and detachment is

Aim: To determine a value for the spring’s force constant‚ k. Introduction: Hooke’s Law indicates the relationship between the amount of extension‚ e‚ of a spring to the size of the force‚ F‚ acing on it. This relationship may be written as :- F = ke F = ke where k is a constant for which particular spring you are using. It is the force constant of the spring. * The force applying on the spring‚ F‚ is denoted by Newton in SI Units. (N) * The amount of extension of the spring

Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often
