Anti-satellite Weapon
Anti-satellite weapons (ASAT) are space weapons designed to incapacitate or destroy satellites for strategic or tactical purposes. Several nations possess operational ASAT systems. Although no ASAT system has been utilised in warfare, a few countries (China, India, Russia, United Kingdom and the United States) have successfully shot down their own satellites to demonstrate their ASAT capabilities in a show of force. ASATs have also been used to remove decommissioned satellites. ASAT roles include: defensive measures against an adversary's space-based and nuclear weapons, a force multiplier for a nuclear first strike, a countermeasure against an adversary's anti-ballistic missile defence (ABM), an asymmetric counter to a technologically superior adversary, and a counter-value weapon. Use of ASATs generates space debris, which can collide with other satellites and generate more space debris. A cascading multiplication of space debris could cause Earth to suffer from ...

ASM-135 ASAT
The ASM-135 ASAT is an air-launched anti-satellite multistage missile that was developed by Ling-Temco-Vought's LTV Aerospace division. The ASM-135 was carried exclusively by United States Air Force (USAF) F-15 Eagle fighter aircraft. Development Starting in the late 1950s, the United States began development of anti-satellite weapons. The first US anti-satellite weapon was the Bold Orion Weapon System 199B (also the High Virgo missile, Weapon System 199C, attempted to conduct an ASAT test but failed to intercept its target; High Virgo's test was a few weeks before Bold Orion's). Like the ASM-135, the Bold Orion missile was air-launched, but in this case from a B-47 Stratojet. The Bold Orion was tested on 13 October 1959 against the Explorer 6 satellite.Edited By Bhupendra Jasani, ''Space Weapons and International Security'', A SIPRI Publication, Oxford University Press, 1987. The two-stage Bold Orion missile passed within of Explorer 6. From this distance, only a relatively l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspartate Aminotransferase
Aspartate transaminase (AST) or aspartate aminotransferase, also known as AspAT/ASAT/AAT or (serum) glutamic oxaloacetic transaminase (GOT, SGOT), is a pyridoxal phosphate (PLP)-dependent transaminase enzyme () that was first described by Arthur Karmen and colleagues in 1954. AST catalyzes the reversible transfer of an α-amino group between aspartate and glutamate and, as such, is an important enzyme in amino acid metabolism. AST is found in the liver, heart, skeletal muscle, kidneys, brain, red blood cells and gall bladder. Serum AST level, serum ALT (alanine transaminase) level, and their ratio ( AST/ALT ratio) are commonly measured clinically as biomarkers for liver health. The tests are part of blood panels. The half-life of total AST in the circulation approximates 17 hours and, on average, 87 hours for ''mitochondrial'' AST. Aminotransferase is cleared by sinusoidal cells in the liver. Function Aspartate transaminase catalyzes the interconversion of aspartate and α-k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Association For Science In Autism Treatment
The Association for Science in Autism Treatment (ASAT) is a non-profit autism organization. It was founded in 1998 and is currently based in Hoboken, New Jersey. Members of its advisory board include Eric Fombonne and Stephen Barrett, Tristam Smith was one of its board members until his death in August 2018. A report by the Association for Behavior Analysis International mentioned ASAT's website as a useful resource for parents of children with autism, as does the website of the University of North Texas and that of the University of Michigan Health System. Views ASAT has warned against chelation therapy as an autism treatment, noting that two children have been reported to have died as a result of this therapy, and concluding that "there is not enough scientific evidence available at this time to advocate a role for chelation of heavy metals in the treatment of autism, and there is potential for adverse side effects." They take a similar viewpoint with regard to the use of se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
