In 1932 A. Ya. Khinchin gave the first partial solution of the celebrated 1931 αβ Conjecture of L.G. Schnirelmann and E. Landau of the density of sums of sets on integers, which was completely proved in 1942 by H.B. Mann.
Khinchin's theorem is proved along with theorems of P. Scherk...
The objectives undertaken in this study were:
1) to develop means of identifying the immature stages of
the known insect predators and parasites of the Douglas-fir beetle; 2) to investigate the possible distribution,
spatially and/or temporal, of the known insect predators
and parasites in standing trees infested by the Douglas-fir...
Commerical preparations and published formulations using reagent chemicals for seawater substitutes were not biologically acceptable to Mytilus edulis embryos, in that calcification did not occur. When Leslie coarse hide salt was used as the source of NaCl for literature formulations, most formulas provided some success in the development, growth and...
Some kinetics of the oxygen requirement of amine oxidases
have been investigated using bovine plasma monoamine oxidase (PAO)
and pea seedling diamine oxidase (DAO). A system is described for
studying enzyme reactions under controlled oxygen tension and in an
O₂-free N₂ atmosphere.
O₂ Km values were determined at two different...
