Ralph Walter Graystone Wyckoff, Sr. (August 9, 1897 – November 3, 1994), or simply Ralph Wyckoff, was an American chemist and pioneer of X-ray crystallography. He also made contributions to vaccine developments against epidemic typhus and other viruses. Biography Wyckoff was the son of judge Abram Ralph Wyckoff and Ethel Agnes Catchpole. He studied at Hobart College, where he obtained a Bachelor of Science in 1916. He continued his studies at Cornell University, where he obtained his Ph.D. in 1919. In 1916, he published his first scientific paper (of more than 400) at the age of nineteen in the ''Journal of the American Chemical Society''. Under Shoji Nishikawa, he presented his thesis about the crystallographic resolution of the structures of NaNO3 and CsICl2 in 1919. Wyckoff continued working in X-ray crystallography and wrote several books about the topic. Wyckoff's 1922 book, ''The Analytical Expression of the Results of the Theory of Space Groups'', contained tables wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Western Equine Encephalitis Virus
Western equine encephalitis virus is the causative agent of the relatively uncommon viral disease Western equine encephalitis (WEE). An alphavirus of the family ''Togaviridae'', the WEE virus is an arbovirus (arthropod-borne virus) transmitted by mosquitoes of the genera ''Culex'' and '' Culiseta''. WEE is a recombinant virus between two other alphaviruses, an ancestral Sindbis virus-like virus, and an ancestral Eastern equine encephalitis virus-like virus. There have been under 700 confirmed cases in the U.S. since 1964. This virus contains an envelope that is made up of glycoproteins and nucleic acids. The virus is transmitted to people and horses by bites from infected mosquitoes ('' Culex tarsalis'' and '' Aedes taeniorhynchus'') and birds during wet, summer months. According to the CDC, geographic occurrence for this virus is worldwide, and tends to be more prevalent in places in and around swampy areas where human populations tend to be limited. In North America, WEE i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Arizona Faculty
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in t ...

Macromolecule
A macromolecule is a "molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass." Polymers are physical examples of macromolecules. Common macromolecules are biopolymers (nucleic acids, proteins, and carbohydrates). and polyolefins (polyethylene) and polyamides (nylon). Synthetic macromolecules Many macromolecules are synthetic polymers (plastics, synthetic fibers, and synthetic rubber. Polyethylene is produced on a particularly large scale such that ethylene is the primary product in the chemical industry. Macromolecules in nature * Proteins are polymers of amino acids joined by peptide bonds. * DNA and RNA are polymers of nucleotides joined by phosphodiester bonds. These nucleotides consist of a phosphate group, a sugar ( ribose in the case of RNA, deoxyribose in the case of DNA), and a nucleotide base (either adenine, guan ...
