Welton Taylor
Welton Ivan Taylor (November 12, 1919 – November 1, 2012) was an American microbiologist, inventor and civil rights activist. He is known for his work on Food microbiology, food-borne pathogens, notably for developing tests for ''Salmonella'' and for inventing the XLD agar, XLD (Xylose Lysine Deoxycholate) agar, which can be used to isolate ''Salmonella'' and ''Shigella'' bacteria. After obtaining his PhD at the University of Illinois at Urbana-Champaign, and research relevant to infections of soldiers' wounds at the university's College of Medicine, Taylor joined the food processing company JBS USA#History, Swift & Company, developing for them an accurate test for the contamination of food with salmonella. This set the direction for his subsequent research, undertaken mostly at Microbiologist-in-Chief at Chicago's Children's Memorial Hospital, on different ways of detecting specific pathogens accurately and quickly, in a clinical setting. Taylor was a life-long civil-rig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birmingham, Alabama
Birmingham ( ) is a city in the north central region of the U.S. state of Alabama. Birmingham is the seat of Jefferson County, Alabama's most populous county. As of the 2021 census estimates, Birmingham had a population of 197,575, down 1% from the 2020 Census, making it Alabama's third-most populous city after Huntsville and Montgomery.

Clostridium Botulinum
''Clostridium botulinum'' is a Gram-positive, rod-shaped, anaerobic, spore-forming, motile bacterium with the ability to produce the neurotoxin botulinum. The botulinum toxin can cause botulism, a severe flaccid paralytic disease in humans and other animals, and is the most potent toxin known to mankind, natural or synthetic, with a lethal dose of 1.3–2.1 ng/kg in humans.(2010).

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
93rd Infantry Division (United States)
The 93rd Infantry Division was a "colored" segregated unit of the United States Army in World War I and World War II. However, in World War I only its four infantry regiments, two brigade headquarters, and a provisional division headquarters were organized, and the divisional and brigade headquarters were demobilized in May 1918.Rinaldi, p. 54 Its regiments fought primarily under French command in that war. During tough combat in France, they soon acquired from the French the nickname ''Blue Helmets'' (french: Casques Bleus), as these units were issued horizon blue French Adrian helmets. This referred to the service of several of its units with the French Army during the Second Battle of the Marne. Consequently, its shoulder patch became a blue French helmet, to commemorate its service with the French Army during the German spring offensive. The division was reactivated with the "colored" infantry designation on 15 May 1942 at Fort Huachuca, Arizona, and shipped overseas in 19 ...

Field Artillery Branch (United States)
The Field Artillery Branch is a combat arms branch of the United States Army that is responsible for field artillery. Historical background The U.S. Army Field Artillery branch traces its origins to 17 November 1775 when the Continental Congress, unanimously elected Henry Knox "Colonel of the Regiment of Artillery". The regiment formally entered service on 1 January 1776. During the 19th Century a total of seven Artillery regiments were formed which contained a mixture of "heavy" artillery companies and "light" artillery batteries. The light artillery batteries took the role of field artillery although they did not use that designation. The seven artillery regiments were designated as regiments of artillery and were not distinguished as being either "coast" or "field" artillery as was the practice in the 20th Century. In the reorganization of the Army by the Act of 2 February 1901, the seven Artillery regiments were reorganized as the Artillery Corps. The Corps was split into ...

Pacific Ocean Theater Of World War II
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reserve Officers' Training Corps
The Reserve Officers' Training Corps (ROTC ( or )) is a group of college- and university-based officer-training programs for training commissioned officers of the United States Armed Forces. Overview While ROTC graduate officers serve in all branches of the U.S. military, the U.S. Marine Corps, the U.S. Space Force, and the U.S. Coast Guard do not have their own respective ROTC programs; rather, graduates of Naval ROTC programs have the option to serve as officers in the Marine Corps contingent on meeting Marine Corps requirements. In 2020, ROTC graduates constituted 70 percent of newly commissioned active-duty U.S. Army officers, 83 percent of newly commissioned U.S. Marine Corps officers (through NROTC), 61 percent of newly commissioned U.S. Navy officers and 63 percent of newly commissioned U.S. Air Force officers, for a combined 56 percent of all active-duty officers in the Department of Defense commissioned that year. Under ROTC, a student may receive a competitive, mer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacteriology
Bacteriology is the branch and specialty of biology that studies the morphology, ecology, genetics and biochemistry of bacteria as well as many other aspects related to them. This subdivision of microbiology involves the identification, classification, and characterization of bacterial species. Because of the similarity of thinking and working with microorganisms other than bacteria, such as protozoa, fungi, and viruses, there has been a tendency for the field of bacteriology to extend as microbiology. The terms were formerly often used interchangeably. However, bacteriology can be classified as a distinct science. Overview Definition Bacteriology is the study of bacteria and their relation to medicine. Bacteriology evolved from physicians needing to apply the germ theory to address the concerns relating to disease spreading in hospitals the 19th century. Identification and characterizing of bacteria being associated to diseases led to advances in pathogenic bacteriology. K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Valedictorian
Valedictorian is an academic title for the highest-performing student of a graduating class of an academic institution. The valedictorian is commonly determined by a numerical formula, generally an academic institution's grade point average (GPA) system, but other methods of selection may be used or factored in such as community service or extra-curricular activity. The term is an Anglicised derivation of the Latin ''vale dicere'' ("to say farewell"), historically rooted in the valedictorian's traditional role as the final speaker at the graduation ceremony commencement before the students receive their diplomas. The valedictory address, also known as the valediction, is generally considered a final farewell to classmates, before they disperse to pursue their individual paths after graduating. The term is not widely used or known outside the US, although some countries may award equivalent titles. In Australia, the title is sometimes awarded to a member of a graduating universit ...
