Mach number

Mach number (Ma or M) (generally pronounced /ˈmɑːk/, sometimes /ˈmɑːx/ or /ˈmæk/) is the speed of an object moving through air, or any fluid substance, divided by the speed of sound as it is in that substance. It is commonly used to represent an object's (such as an aircraft or missile) speed, when it is travelling at (or at multiples of) the speed of sound.

\ M = \frac {{v_s}}{{u}}

where

\ M is the Mach number
\ v_s is the speed of the source (the object relative to the medium) and
\ u is the speed of sound in the medium

Radiation hardening

Radiation hardening is a method of designing and testing electronic components and systems to make them resistant to damage or malfunctions caused by high-energy subatomic particles and electromagnetic radiation[1], such as would be encountered in outer space, high-altitude flight, around nuclear reactors, or during warfare.

Mumps

Mumps or epidemic parotitis is a viral disease of the human species, caused by the mumps virus. Prior to the development of vaccination and the introduction of avaccine, it was a common childhood disease worldwide, and is still a significant threat to health in the third world

Bioversity International

Bioversity International is one of 15 agricultural research centres supported by the Consultative Group on International Agricultural Research (CGIAR). It is dedicated to the conservation and use of agricultural biodiversity to improve the livelihoods of poor people. The organization is highly decentralized, with about 320 staff working from 16 offices worldwide. Headquarters is in Maccarese, outside Rome, Italy, with four regional offices: Cali, Colombia; Nairobi, Kenya; Maccarese, Italy; and Serdang, Malaysia. (The office in Aleppo, Syria, was mothballed on 1 January 2009.)

Dumdum fever

Visceral leishmaniasis (VL), also known as kala-azar, black fever, and Dumdum fever,[1]:426 is the most severe form of leishmaniasis. Leishmaniasis is a diseasecaused by protozoan parasites of the Leishmania genus. It is the second-largest parasitic killer in the world (after malaria), responsible for an estimated 500,000 cases each year worldwide.[2] The parasite migrates to the internal organs such as liver, spleen (hence 'visceral)' and bone marrow and if left untreated will almost always result in the death of the host. Signs and symptoms include fever, weight loss, mucosal ulcers, fatigue, anemia and substantial swelling of the liver and spleen. Of particular concern, according to the World Health Organization (WHO), is the emerging problem of HIV/VL co-infection
