It has been established that the change in the composition of the total lipids and the fall in the fatty acid content depend on the initial maize genotype. A decrease in the amount of unsaponifiable substances in the grain of mutants is accompanied by qualitative changes in the composition regardless of the nature of the genotype.Scientific-Research Institute of Biology Dnepropetrovsk State university.

N,N-Diethylcarbamoyl-4,5-epoxy-2-hexenoic acid reacts with ketones in the presence of anhydrous FeCl3 to give 2,2,4-trialkyl-5-[2-N,N-diethylcarbamoyl(vinylene)]-1,3-dioxolane. 2,2,4-Trimethyl-5-(1-propenyl-3-hydroxy)-1,3-dioxolane is formed in the reduction of 2,2,4-trimethyl-5-[2-carbethoxy(vinylene)]-1,3-dioxolane withlithium aluminum hydride. 相似文献

A turbulent wake model, based on the Reynolds, energy and turbulence dissipation equations together with the closing relations
for the turbulent transport coefficients, is proposed. A comparative investigation of swirled momentumless wakes with zero
and nonzero angular momentum is carried out.

A system of differential equations is proposed to describe turbulent flows of incompressible fluid boundary layer type with constant thermophysical characteristics A turbulent temperature conductivity is introduced which is expressed in terms of the energy and scale of turbulence, the dimensionless gradients of the mean velocity and turbulence energy, and the dimensionless distance, to the surface being streamlined. This system is integrated on an electronc computer by the mesh method for the flow in a flat-plate boundary layer with different Prandtl numbers (0.2P100) For air (P=0.71) the system is integrated for nonzero values of the transverse mean velocity component on the streamlined surface (0vW/U0.0045).Moscow.

Formulas for the stresses and displacements in an annular plate with cylindrical anisotropy are obtained with allowance for the time factor. Different cases of loading of the inside and outside edges of the plate are examined.Mekhanika Polimerov, Vol. 2, No. 3, pp. 403–412, 1966 相似文献
