American Sociological Association
The American Sociological Association (ASA) is a non-profit organization dedicated to advancing the discipline and profession of sociology. Founded in December 1905 as the American Sociological Society at Johns Hopkins University by a group of fifty people, the first president of the association would be Lester Frank Ward. Today, most of its members work in academia, while around 20 percent of them work in government, business, or non-profit organizations. ASA publishes ten academic journals and magazines, along with four section journals. Among these publications, the '' American Sociological Review'' is perhaps the best known, while the newest is an open-access journal titled Socius: Sociological Research for a Dynamic World'. '' Contexts'' is one of their magazines, designed to share the study of sociology with other disciplines as well as the public. The ASA is currently the largest professional association of sociologists in the world, even larger than the International ...

Antisperm Antibodies
Antisperm antibodies (ASA) are antibodies produced against sperm antigens. Types Antisperm antibodies are immunoglobulins of IgG, IgA, and/or IgM, which are directed against sperm antigens. ASA can be detected in ejaculate, cervical mucus, follicular fluid, and blood serum of both males and females. While IgG and IgA might be present in blood serum and/or genital tract fluids, IgM is only present in blood serum. IgG occurring in genital tract fluids is either produced locally or transuded from blood serum, whereas IgA (secretory type) is always produced locally. Causes Traditionally, the breakdown of the blood-testis barrier had been established as the cause of ASA production. This mechanism had been advocated in testicular trauma and surgery, orchitis ( mumps), varicocele, bacterial infections (epididymitis, prostatitis), testicular cancer, and unprotected anal intercourse. However, the association between aforementioned conditions and ASA production is controversi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Studies Association
The African Studies Association (ASA) is a US-based association of scholars, students, practitioners, and institutions with an interest in the continent of Africa. Founded in 1957, the ASA is the leading organization of African Studies in North America, with a global membership of approximately 2000. The association's headquarters are at Rutgers University in New Jersey. The ASA holds annual conferences and virtual events for its members year-round. As a result of racial and political disputes over exclusion from leadership positions of black academics and ASA leaders' ties with the US intelligence and military in the mid-twentieth century, the ASA split in 1968, when the Black Caucus of the ASA, led by John Henrik Clarke, founded the African Heritage Studies Association (AHSA). The ASA is different from the African Studies Association of Africa (ASAA), which was founded at the University of Cape Town in October 1-2, 2012. Awards given by ASA ASA Best Book Prize The ASA ...

ASA Physical Status Classification System
The ASA physical status classification system is a system for assessing the fitness of patients before surgery. In 1963 the American Society of Anesthesiologists (ASA) adopted the five-category physical status classification system; a sixth category was later added. These are: #Healthy person. #Mild systemic disease. #Severe systemic disease. #Severe systemic disease that is a constant threat to life. #A moribund person who is not expected to survive without the operation. #A declared brain-dead person whose organs are being removed for donor purposes. If the surgery is an emergency, the physical status classification is followed by "E" (for emergency) for example "3E". Class 5 is usually an emergency and is therefore usually "5E". The class "6E" does not exist and is simply recorded as class "6", as all organ retrieval in brain-dead patients is done urgently. The original definition of emergency in 1940, when ASA classification was first designed, was "a surgical procedure wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acoustical Society Of America
The Acoustical Society of America (ASA) is an international scientific society founded in 1929 dedicated to generating, disseminating and promoting the knowledge of acoustics and its practical applications. The Society is primarily a voluntary organization of about 7500 members and attracts the interest, commitment, and service of many professionals. History In the summer of 1928, (See Wallace Clement Sabine.) Floyd R. Watson and Wallace Waterfall (1900–1974), a former doctoral student of Watson, were invited by UCLA's Vern Oliver Knudsen to an evening dinner at Knudsen's beach club in Santa Monica. The three physicists decided to form a society of acoustical engineers interested in architectural acoustics. In the early part of December 1928, Wallace Waterfall sent letters to sixteen people inquiring about the possibility of organizing such a society. Harvey Fletcher offered the use of the Bell Telephone Laboratories at 463 West Street in Manhattan as a meeting place for an or ...

American Society Of Anesthesiologists
The American Society of Anesthesiologists (ASA) is an educational, research and scientific association of physicians organized to raise the standards of the medical practice of anesthesiology and to improve patient care. As of 2021, the organization included more than 55,000 national and international members and has more than 100 full-time employees. History Anesthesiology's roots date back to the mid-19th century. On March 30, 1842, Crawford Long, M.D. administered the first ether anesthetic for surgery and operated to remove a tumor from a patient's neck. After the surgery, the patient revealed that he felt nothing and was not aware the surgery was over until he awoke. This was the start of a specialty critical to modern medicine, anesthesiology. In 1905, nine physicians (from Long Island, N.Y.) organized the first professional anesthesia society. In 1911, the Society expanded to 23 members and became the New York Society of Anesthetists. Over the next 25 years, involvement i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Society Of Agronomy
The American Society of Agronomy (ASA) is a scientific and professional society of agronomists and scientists of related disciplines, principally in the United States but with many non-U.S. members as well. About It was founded December 13, 1907 with the objective of 'the increase and dissemination of knowledge concerning soils, crops, and the conditions affecting them. One of its founding members was Charles Piper, who would become its president in 1914. The first president was Mark A. Carleton and the first annual meeting was held in Washington, D.C., in 1908.

Accessible Surface Area
The accessible surface area (ASA) or solvent-accessible surface area (SASA) is the surface area of a biomolecule that is accessible to a solvent. Measurement of ASA is usually described in units of square angstroms (a standard unit of measurement in molecular biology). ASA was first described by Lee & Richards in 1971 and is sometimes called the Lee-Richards molecular surface. ASA is typically calculated using the 'rolling ball' algorithm developed by Shrake & Rupley in 1973. This algorithm uses a sphere (of solvent) of a particular radius to 'probe' the surface of the molecule. Methods of calculating ASA Shrake–Rupley algorithm The Shrake–Rupley algorithm is a numerical method that draws a mesh of points equidistant from each atom of the molecule and uses the number of these points that are solvent accessible to determine the surface area. The points are drawn at a water molecule's estimated radius beyond the van der Waals radius, which is effectively similar to ‘rollin ...
