The effect of temperature (5-70 ° C), viscosity, and the nature of fluid on the hydrodynamic permeability (HDP) coefficient of inorganic ultrafiltration membranes was experimentally studied. The direct influence of fluid viscosity on the HDP coefficient within a high-temperature range, where this coefficient decreases with an increase in temperature, was established. A semiempirical expression for the HDP coefficient of a porous layer was proposed, which made it possible to interpret both monotonous and extremal dependences of the HDP coefficient on temperature for hydrophilic and hydrophobic porous media

The article is devoted to the analysis of the current state of innovative development of agriculture in Russia. Innovations are becoming a determining factor in upgrading the efficiency of economic development under conditions when market dynamics undergo revolutionary changes. An integral component of innovation processes is an unbiased assessment of the current state and dynamics of innovation indicators. However, the existing methodology and approaches to estimating innovative development at the macroeconomic level do not provide an objective account of implementation of the given process regarding particular sectors of the economy. The methodology of this research is based on the works of Russian and foreign economists, national laws and regulations, the Oslo Manual on the nature, content and measurement of innovative potential, as well as materials from periodicals on assessment of innovations, and scientific approaches to the study of innovative advancement in agriculture. Specific factors discouraging the process of introducing innovations in agriculture have been revealed. Analysis of key indicators demonstrating the level of innovative development is performed. The ways of increasing performance of innovative activity in agricultural sector are proposed. The prioritized measures for increasing innovation activity in agriculture were formulated. The measures needed to create a multi-level system of training and retraining specialists employed in agribusiness and measures for the development of institutional infrastructure for innovations, development and adoption of legislative and normative acts regulating and stimulating innovative activity have been proposed.
