Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Artificial Silk
Artificial silk or art silk is any synthetic fiber which resembles silk, but typically costs less to produce. Frequently, "artificial silk" is just a synonym for rayon. When made out of bamboo viscose it is also sometimes called bamboo silk. The first successful artificial silks were developed in the 1890s of cellulose fiber and marketed as ''art silk'' or ''viscose'', a trade name for a specific manufacturer. In 1924, the name of the fiber was officially changed in the U.S. to rayon, although the term ''viscose'' continued to be used in Europe. The material is commonly referred to in the industry as ''viscose rayon''. In 1931, Henry Ford hired chemists Robert Boyer (chemist), Robert Boyer and Frank Calvert to produce artificial silk made with soybean fibers. They succeeded in making a textile fiber of spun soy protein fibers, hardened or tanned in a formaldehyde bath, which was given the name Azlon. It was usable for making suits, felt hats, and overcoats. Though pilot produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

His father, who was from Connecticut, was an abolitionist and was known to purchase slaves in order to free them. During the Civil War his father moved north, but the family remained in their home until the time of Sherman's March.

Psychological Review
''Psychological Review'' is a bimonthly peer-reviewed academic journal that covers psychological theory. It was established by James Mark Baldwin (Princeton University) and James McKeen Cattell (Columbia University) in 1894 as a publication vehicle for psychologists not connected with the laboratory of G. Stanley Hall (Clark University), who often published in his ''American Journal of Psychology''.

Binswanger's Disease
Binswanger's disease, also known as subcortical leukoencephalopathy and subcortical arteriosclerotic encephalopathy, is a form of small-vessel vascular dementia caused by damage to the white brain matter. White matter atrophy can be caused by many circumstances including chronic hypertension as well as old age.Giovannetti, T. Personal Interview. 16 October 2009 This disease is characterized by loss of memory and intellectual function and by changes in mood. These changes encompass what are known as executive functions of the brain. It usually presents between 54 and 66 years of age, and the first symptoms are usually mental deterioration or stroke. It was described by Otto Binswanger in 1894, and Alois Alzheimer first used the phrase "Binswanger's disease" in 1902. However, Jerzy Olszewski is credited with much of the modern-day investigation of this disease which began in 1962. Signs and symptoms Symptoms include mental deterioration, language disorder, transient ischemic attack ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto Binswanger
Otto Ludwig Binswanger (; ; 14 October 1852 in Scherzingen, Münsterlingen – 15 July 1929 in Kreuzlingen) was a Swiss psychiatrist and neurologist who came from a famous family of physicians; his father was founder of the Kreuzlingen Sanatorium, and he was uncle to Ludwig Binswanger (1881–1966) who was a major figure in the existential psychology movement. He was brother-in-law to physiotherapist Heinrich Averbeck (1844–1889). Other notable family members include his son-in-law Hans-Constantin Paulssen (1892-1984), who was the first president of the BDA (Bundesvereinigung der Deutschen Arbeitgeberverbände) (Confederation of German Employers' Associations).

Edward John Bevan
Edward John Bevan (11 December 1856 – 17 October 1921) was an English chemist. He became a leader in the affairs of the Society of Public Analysts and editor of The Analyst. Bevan was notable for his caustic wit. He was born in Birkenhead. After graduating, he became a chemist at the Scottish paper making firm of Alexander Cowan & Co. He met Charles Frederick Cross, and the pair then attended Owens College, Manchester. Cross who was interested in cellulose technology went into partnership with Bevan in 1885, setting up as analytical and consulting chemists in New Court, Lincoln's Inn in London. In 1888 they published what was to become a standard work on paper making. In 1892, together with another partner, Clayton Beadle (who was also an authority on paper making) they took out a patent for viscose which became the basis for the viscose, rayon and cellophane industries. In 1894 Cross and Bevan took out a patent for the manufacture of cellulose acetate - this was to become th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
