Doctor Of Engineering
The Doctor of Engineering, or Engineering Doctorate, (abbreviated DEng, EngD, or Dr-Ing) is a degree awarded on the basis of advanced study and a practical project in the engineering and applied science for solving problems in the industry. In the United States, it is a terminal professional doctorate. A DEng/EngD is equivalent to a PhD in engineering, but different in that it has a solid industrial base and an additional taught element. The degree is usually aimed toward working professionals. The DEng/EngD along with the PhD represents the highest academic qualification in engineering, and the successful completion of either in engineering is generally required to gain employment as a full-time, tenure-track university professor or postdoctoral researcher in the field. However, due to its nature, a DEng/EngD graduate might be more suitable for the Professor of Practice position. Individuals can use the academic title doctor, which is often represented via the English honorific "Dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1929 Wall Street Crash
The Wall Street Crash of 1929, also known as the Great Crash, was a major American stock market crash that occurred in the autumn of 1929. It started in September and ended late in October, when share prices on the New York Stock Exchange collapsed. It was the most devastating stock market crash in the history of the United States, when taking into consideration the full extent and duration of its aftereffects.

Background The "Roaring Twenties", the decade following World War I that led to the crash, was a time of wealth and excess. Building on post-war optimism, rural Americ ...

Chemical Warfare Service
The Chemical Corps is the branch of the United States Army tasked with defending against chemical, biological, radiological, and nuclear (CBRN) weapons. The Chemical Warfare Service was established on 28 June 1918, combining activities that until then had been dispersed among five separate agencies of the United States federal government. It was made a permanent branch of the Regular Army by the National Defense Act of 1920. In 1945, it was redesignated the Chemical Corps. History Origins Discussion of the topic dates back to the American Civil War. A letter to the War Department dated 5 April 1862 from New York City resident John Doughty proposed the use of chlorine shells to drive the Confederate Army from its positions. Doughty included a detailed drawing of the shell with his letter. It is unknown how the military reacted to Doughty's proposal but the letter was unnoticed in a pile of old official documents until modern times. Another American, Forrest Shepherd, also propo ...

American University
The American University (AU or American) is a private federally chartered research university in Washington, D.C. Its main campus spans 90 acres (36 ha) on Ward Circle, mostly in the Spring Valley neighborhood of Northwest D.C. AU was chartered by an Act of Congress in 1893 at the urging of Methodist bishop John Fletcher Hurst, who sought to create an institution that would promote public service, internationalism, and pragmatic idealism.

Helium
Helium (from el, ἥλιος, helios, lit=sun) is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling and melting point are the lowest among all the elements. It is the second lightest and second most abundant element in the observable universe (hydrogen is the lightest and most abundant). It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and in Jupiter, due to the very high nuclear binding energy (per nucleon) of helium-4, with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, the vast majority of which was formed during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
