Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria.The 313 members of the genus [2] [3] demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. [4]
The pits of the first nuclear weapons were solid, with an urchin neutron initiator in their center. The Gadget and Fat Man used pits made of 6.2 kg of solid hot pressed plutonium-gallium alloy (at 400 °C and 200 MPa in steel dies – 750 °F and 29,000 psi) half-spheres of 9.2 cm (3.6 in) diameter, with a 2.5 cm (1 in) internal cavity for the initiator.
Gallium-70 can decay through both beta minus decay and electron capture. Gallium-67 is unique among the light isotopes in having only electron capture as a decay mode, as its decay energy is not sufficient to allow positron emission. [31] Gallium-67 and gallium-68 (half-life 67.7 min) are both used in nuclear medicine.
While the Cold War itself never escalated into direct confrontation, there were a number of conflicts and revolutions related to the Cold War around the globe, spanning the entirety of the period usually prescribed to it (March 12, 1947 to December 26, 1991, a total of 44 years, 9 months, and 2 weeks).

Pseudomonas stutzeri is a Gram-negative soil bacterium that is motile, has a single polar flagellum, and is classified as bacillus, or rod-shaped. [ 1 ] [ 2 ] While this bacterium was first isolated from human spinal fluid, [ 3 ] it has since been found in many different environments due to its various characteristics and metabolic capabilities ...
World map of alliances in 1970 The 1975 Apollo-Soyuz space rendez-vous, one of the attempts at cooperation between the US and the USSR during the détenteThe Cold War (1962–1979) refers to the phase within the Cold War that spanned the period between the aftermath of the Cuban Missile Crisis in late October 1962, through the détente period beginning in 1969, to the end of détente in the ...
[6] [7] This discrepancy soon became known as the gallium anomaly. Following the report of the anomaly in 2006, physicists began to explore potential explanations for the observed deficit. A 2007 analysis [ 8 ] examined the data within frameworks of two- and three-neutrino mixing, considering the possibility of electron neutrinos oscillating ...
The Cold War was a period of global geopolitical rivalry between the United States and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc, which lasted from 1947 until the dissolution of the Soviet Union in 1991.
