Historical accounts give swords the status of legendary, mystical, impervious, and empowering. Swords were seen as giving the wieldier power, and the wieldier seen as being of high social standing, according to the quality of the sword. Both the Viking sword and Katana were masterfully designed according to the environment and materials available in both demographics. The Vikings were not one specific organized group of people. They started out as multiple smaller unorganized tribes. The…

ABSTRACT: Terpolymer / kaolinite microcomposites were synthesized by 2:2:1 molar ratio of aniline, anthranilic acid and o-phenylenediamine monomers, respectively using various percentages of kaolinite clay via modified in situ oxidative ter-polymerization. The results were confirmed by FT-IR and UV-Vis absorption spectra of terpolymers / kaolinite composites. The thermal behaviour of the terpolymer and composites was studied. Terpolymers / kaolinite composites were thermally more stable than…

History Final The Communist Manifesto The Communist Manifesto is a pamphlet written by Karl Marx and Friedrich Engels and published on February 21, 1848. The Manifesto is a call to arms against capitalism and the bourgeoisie. They illustrate in simple terms so everyone can understand, that with the overthrow of unequal hierarchies of feudalism, came a split between classes because of capitalism. They state “Society as a whole is more and more splitting up into two great hostile camps - the…

Several decades ago when technology was only developing, all the production work were done by work force. It took an extensive amount of time for a production work to occur. Hence this could not meet the requirements of producing more outputs in a day. Therefore, the concept of assembly lines was thought to counter the problem of delayed production work and cost minimization. While the invention of assembly line was a landmark in the engineering evolution of history, the widespread use of…

The succeeding project is an accumulation of articles that focused on the effects of deforestation and the taken determinations to reverse the process with the use of reforestation. The front-runners of deforestation for years were profit of corporations or the prestige of kingdom royalty. As progress was guilty of destroying trees, which would lead to future changes in the ecosystem; and the long-term effects on the environment would go ignored. The once, booming agricultural environment of…

after his death, preserved in the mountainous area where he was discovered. His bones indicated that Otzi lived most of his life in the steep, cold mountains, and there were traces of arsenic in his hair, which suggested that he had contact with the smelting of copper. He had a long gash in his hand points, a flint arrow that was stuck in his back, and had a severed artery, so Otzi did not die from natural causes. Although the cause of his death is known, not much about the reasons for why he…

evaporation would potentially contain acidic properties that would rain down again. Oxidation Sulfur dioxide and nitrogen oxides enter the atmosphere via emissions from the combustion of sulfur-containing fuels, such as oil and coal, and through the smelting of sulfur-containing ores, such as copper, lead and zinc. Scientists now know that high concentrations of nitric acid and sulfuric acid in rain is caused by atmospheric oxidation of nitrogen oxides and sulfur dioxide, and that these acids…

came before it. First the Mesopotamians, and then the Egyptians, moved from an agricultural and herding based culture to a new form of culture called civilization. This new culture was “marked by the appearance of urban centers, the mastery of smelting and with it the techniques for making metal tools and weapons, and the invention of writing”(“The Western Heritage”, xxxvii). Their influence spread to the Grecian island of Crete, where the Minoan civilization was created. The Minoans had a…

the Cape Breton Island in Nova Scotia, Canada. During the early 1900s, steel production began at this location and carried on for over 80 years. Throughout this duration of time, at least 700 000 tonnes of toxic by-products were produced due to smelting and steel production processes. Some of the by-products produced were total petroleum hydrocarbons (TPHs), benzene, toluene, ethyl-benzene, xylene (BTEX), polycyclic aromatic hydrocarbons (PAHs) and heavy metals. The toxic by-products were…

Multiple Sclerosis Cluster in El Paso? An Analysis of the Data Andre L. Beasley Sr. University of Saint Francis Background A Texas resident with multiple sclerosis (MS) contacted the Texas Department of Health (TDH) to report a suspected cluster of MS cases among people that spent their childhood in the Kern-Place-Mission Hills area of El Paso, Texas in 1994 (Henry, Garabedian, Wagner, and Shire, 2007, p. 5). Fifteen individuals that lived in the area from the 1940s through the 1960s, had…
