Bachelor Of Science
A Bachelor of Science (BS, BSc, SB, or ScB; from the Latin ') is a bachelor's degree awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Southgate Shaler, who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through the influence of Louis Agassiz, who had much to do in shaping the plans of this School." Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follow the Oxford a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trojan Powder Company
The Trojan Powder Company was an American manufacturer of explosives founded in 1904 that made nitro-starch powder. It had a manufacturing complex in Allentown, Pennsylvania, and another facility at Roberts Landing near San Lorenzo, California. The company thrived during World War I (1914–18), continued research and development in the interwar-period, and during World War II operated a large facility in Sandusky, Ohio, under contract to the army. After the war, production scaled back. A facility in Oregon was sold for use by the Trojan Nuclear Power Plant. In 1967 Trojan Powders became a division of Commercial Solvents Corporation (CSC). It was later acquired by the Ensign-Bickford Company. Background The chemists F.B. Holmes and Jesse B. Bronstein discovered how to produce a stable nitrostarch while working at DuPont's Eastern Laboratories. Between 1905 and 1908 Holmes obtained various patents related to stabilization of nitrostarch powders. Because the powder did not con ...

Frank Phillips (oil Industrialist)
Frank Phillips (November 28, 1873 – August 23, 1950) was the founder of Phillips Petroleum in Bartlesville, Oklahoma (marketed as Phillips 66) in 1917, along with his brother, Lee Eldas "L.E." Phillips Sr. In 2002, Phillips Petroleum merged with Conoco Oil Company and became ConocoPhillips. Early life and education Frank Phillips was born on November 28, 1873 in Scotia, Nebraska where his parents Lucinda and Lewis Franklin Phillips, the county's first magistrate, had a farm; the family moved in 1874 to a small farm in rural southwest Iowa. Frank had ten siblings, including two brothers with whom he later went into business. One notable family member is his sibling Waite Phillips, who founded the Philmont Scout Ranch in New Mexico, a destination for thousands of Boy Scouts to backpack the mountains. A few years later, the Phillips boy began his first occupational endeavor, hiring himself out to area farmers to dig potatoes for 10 cents a day (after completing his chores at hom ...

Gasoline
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades.

Edmund Ronalds
Dr Edmund Ronalds FCS FRSE (18 June 1819 – 9 September 1889) was an English academic and industrial chemist. He was co-author of a seminal series of books on chemical technology that helped begin university teaching of chemical applications for industry, and was a pioneer in the incorporation of advanced research into a manufacturing firm. Upbringing and family He was born on 18 June 1819 at 48 Canonbury Square in Islington. His father Edmund Sr was a London cheesemonger and the brother of inventor Sir Francis Ronalds and his mother Eliza Jemima was the daughter of Dr James Anderson, who ran a respected school in Hammersmith. For most of his childhood the family lived at Brixton Hill but they returned to Islington in 1839 and resided at the east end of Canonbury Place. He was the eldest of at least 12 children. Five of his siblings moved to New Zealand in the 1850s where his sisters married brothers of Harry Atkinson. Another sister spent her last years in Algiers. Two sibli ...

Crude Oil
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other Unconventional (oil & gas) reservoir, unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by Continuous distillation#Continuous distillation of crude oil, distillation, into innume ...

Mine Safety
Mine safety is a broad term referring to the practice of controlling and managing a wide range of hazards associated with the life cycle of mining-related activities. Mine safety practice involves the implementation of recognised hazard controls and/or reduction of risks associated with mining activities to legally, socially and morally acceptable levels. While the fundamental principle of mine safety is to remove health and safety risks to mine workers, mining safety practice may also focus on the reduction of risks to plant (machinery) together with the structure and orebody of the mine. Safety has long been a concern in the mining business, especially in underground mining. The Courrières mine disaster, Europe's worst mining accident, involved the death of 1,099 miners in Northern France on March 10, 1906. This disaster was surpassed only by the Benxihu Colliery accident in China on April 26, 1942, which killed 1,549 miners. While mining today is substantially safer than it was ...

Panama Canal
The Panama Canal ( es, Canal de Panamá, link=no) is an artificial waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean and divides North and South America. The canal cuts across the Isthmus of Panama and is a conduit for maritime trade. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan and the even less popular route through the Arctic Archipelago and the Bering Strait. Colombia, France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of lack of investors' confidence due to engineering problems and a high worker mortality rate. The United States took over the ...

Detonator
A detonator, frequently a blasting cap, is a device used to trigger an explosive device. Detonators can be chemically, mechanically, or electrically initiated, the last two being the most common. The commercial use of explosives uses electrical detonators or the capped fuse which is a length of safety fuse to which an ordinary detonator has been joined. Many detonators' primary explosive is a material called ASA compound. This compound is formed from lead azide, lead styphnate and aluminium and is pressed into place above the base charge, usually TNT or tetryl in military detonators and PETN in commercial detonators. Other materials such as DDNP (diazo dinitro phenol) are also used as the primary charge to reduce the amount of lead emitted into the atmosphere by mining and quarrying operations. Old detonators used mercury fulminate as the primary, often mixed with potassium chlorate to yield better performance. A blasting cap is a small sensitive primary explosive device ge ...
