The methods of choosing the parameters of hydromachines of volume hydrotransmissions of differential planetary tranversing mechanisms of crawler tractors, which provide a minimum turn radium of a tractor and an optimum pressure of working liquid in the volume hydrotransmission with regard to...

Investigations were conducted in Belarussian forests subjected to Chernobyl radioactive fallout. Data are tabulated on radionuclide accumulation in birch sap in 2 forest districts. A mathematical model is presented to calculate the dynamics of volume activity of radionuclides.

Studies were conducted to evaluate the efficiency of 7 biopreparations (Fitoekols-IF [botanical fungicide from Pinus sylvestris and Picea abies], Mycostop [Streptomyces griseoviridis], Phytoverm [Streptomyces avermitilis], Neem Azal-T/S [neem extract], Neko (botanical insecticide), Virin-KS and...

[See FA 38, 3371] Studies on Pinus sylvestris in 1972-73 showed that the m.c. of sapwood and phloem depended on forest type, climatic conditions and stand age.

Distinguishes light-, grey-, green- and dark-barked forms of Populus tremula, the grey-barked form being commonest. The superior green-barked form is described, and brief notes are given on its height and diameter growth, wood properties, propagation, etc. KEYWORDS: Botany general \ tree breeding \ ...
