Physicochemical and biological factors affecting atmospheric methane oxidation in gray forest soils
      
The decline of methane oxidizing activities in gray forest soil upon its conversion into arable land was shown to be caused by major changes in biotic and physicochemical properties of soil.
      
Fungal and bacterial substrate-induced respiration have been distinguished in gray forest and chestnut soils in various ecosystems (forest, grassland, arable soil, fallow land, and shelterbelt) using the antibiotics cycloheximide and streptomycin.
      
Isolation and characterization of lectin from the surface of Grifola frondosa (Fr.) S.F.Gray mycelium
      
Composing the Carlet map with the inverse Gray map, a new family of cyclic quaternary codes is constructed from 5-cyclic
      
A binary code is called ?4-linear if its quaternary Gray map preimage is linear.
      
For any pair of integers r and m, 0 ≤ r ≤ m, we construct a class of quaternary linear codes whose binary images under the Gray map are codes with the parameters of the classical rth-order Reed-Muller code RM(r, m).
      
Under hydrothermal conditions (NpO2)2L·4H2O is not converted to lower hydrates, and above 135°C it decomposes to form a dark gray amorphous product.
      
The kinetics and stoichiometry of catalytic decomposition of hydrazine in 0.01 M NaOH solutions in the presence of unstabilized ("gray" colloid) and stabilized with sodium polyacrylate ("brown" colloid) platinum nanoparticles were studied.
      
Despite higher nanoparticle dispersion, the catalytic activity of the stabilized "brown" colloid is lower than that of the "gray" colloid.
      
The kinetics of catalytic reduction of Np(VI) with formic acid in the presence of Pt nanoparticles of different types ("brown" colloid stabilized with sodium polyacrylate and nonstabilized "gray" colloid) was studied.
      
The catalytic activity of the nonstabilized "gray" colloid exceeds by almost an order of magnitude that of the "brown" colloid, due to the blocking effect of stabilizing polyelectrolyte molecules on the active catalytic centers.
      
For example, we do know that the amount of gray hair correlates quite well with the age of an individual but is in no way related to the mechanisms of his/her aging and probability of death.
      
A new briareidae gray, 1859 (Octocorallia, Gogonacea) from the South Georgia Islands
      
Distribution, Size, and Some Behavioral Characteristics of the Gray Whales Eschrichtius robustusof the Korean Herd in the Coasta
      
Gray whales are observed there from May till November; they stay within 4-5 km of the coast at a depth of no more than 25 m.
      
A preliminary estimation indicates that the Korean gray whale population includes no more than 100 specimens.
      
We examined changes in the oxygen consumption rate, the number of active animals, rate of losses of salts, and the level of cell hydration under conditions of decreased salinity in the mollusks Portlandia arctica(Gray) and Nuculana pernula(O.F.
      
Comparison with Gray's mussel revealed that the northern horse mussel had a higher rate of byssal thread production and a greater thread number by the end of the complete formation of the byssus complex.
      
Distribution of a Little-Known Sea Snake Chitulia belcheri (Gray, 1849) and New Records of Rare Species of the Genus Leioselasma
