Archbishop Oscar Romero of San Salvador was a great hero of the struggles for liberation in Latin America during that region’s "long dark night‚" a period lasting from the 1960s through the 1980s. He was an archbishop very briefly‚ a mere three years‚ 1977-1980‚ and he was an unlikely hero. The upper hierarchy of the Roman Catholic Church in Latin America was firmly allied with the economic and political elite. But Archbishop Romero emerged as the "voice of the oppressed" in El Salvador after he

Germ Line Control of female Sex Determination in Zebrafish In order to identify the sex of a developing embryo‚ many scientists have studied this process called sex determination that allows them to have better understandings on how sex is being determined in either vertebrates or invertebrates. Sex determination is normally determined genetically; however‚ other factors can contribute to its determination. There are numerous determinants that control sex determination‚ but the most important are

from many parties. What needs to be considered from these discussions is the protection of our generations and the future implications of germ line therapy on the environment and humans. These are just a few of the issues that need to be taken into consideration when conducting genetic research to better treat and cure disease. It is relevant to note that germ line therapy is still experimental and possible procedures are based on current scientific research in the development of these procedures

The second is the female perspective where‚ despite the patrol man ’s power‚ his "jeep has a flat" (22) and he doesn ’t speak Spanish so he ’s unable to interpret the woman saying where there is water.

It’s a fact‚ when talking on the subject of war‚ we presume that if the generals and country leaders didn’t start them‚ they would by no means occur. In a book like Storm of Steel by Ernst Junger‚ though‚ there seems to be one more requirement‚ ready and enthusiastic soldiers. Junger would have probably preferred themselves "warriors" or barbarians. It’s within this book that Ernst Junger tells the story of a man who describes and most likely believed that the battlefront of World War I was not a

Carbon steel is steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%. The American Iron and Steel Institute(AISI) defines carbon steel as the following: "Steel is considered to be carbon steel when no minimum content is specified or required for chromium‚cobalt‚ molybdenum‚ nickel‚ niobium‚ titanium‚ tungsten‚ vanadium or zirconium‚ or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0
