To describe the viscosity up to the temperature transcendental polynomials with four or five adjustable parameters
is often used, which devoid of physical meaning. As it is known, the extrapolation of these approximatin ...
The article is devoted to the investigation of the influence of electrohydropulse processing of Zhana-Ozen oil
sludge using the method of probabilistic-deterministic planning of the experiment, in which the mutual ...
When processing coals and oils containing sulfur compounds, the resulting fuel components do not meet the
requirements of the State standards for sulfur content. Sulfur affects negatively the quality of the target ...
Biological characteristics of medicinal plants is largely determined by the place of their growth. This article
presents the results of a study the influence of the industrial zone on the vegetation, the study of the ...
A two-phased solvothermal method was employed to synthesize BiOCl nanoplates using Bi(NO3)3·5H2O, sodium
oleate and KCl as the starting materials. The phases, morphology and optical property of the products
were characterized ...
The new double holmium-calcium tellurite was synthesized by the ceramic technology. The formation of the
