Method for Effective Increasing the Decomposition Rate of Ammonium Perchlorate in Solid Rocket Fuel

open access: yesҚарағанды университетінің хабаршысы. Физика сериясы
Ammonium perchlorate (AP) is a common oxidizer in solid rocket propellants. For devices, the most im- portant parameter of which is the speed of movement, the key correlation is between the jet thrust and the combustion rate of fuels and, consequently ...

Distinct forebrain and cerebellar isozymes of type II Ca^(2+)/calmodulin-dependent protein kinase associate differently with the postsynaptic density fraction [PDF]

open access: yes, 1985
Forebrain and cerebellar Type II Ca2+/calmodulin-dependent protein kinases have different subunit compositions. The forebrain holoenzyme, characterized in our laboratory, is a 650-kDa holoenzyme composed of 50-kDa alpha-subunits and 60-kDa beta-subunits ...
