The paper presents results of the research on the influence of electrokinetic characteristics of fluids on its flow in porous media. Experimental studies have shown the effect of fluid slippage in the channels of porous media due to the electrically charged boundary "liquid-porous medium". It is shown that the change of flow velocity profile and pressure gradient is caused by the display of electrokinetic effects in the filtration of polar liquids.The investigation has shown that the process of the electrolyte solutions filtration in a porous medium is accompanied by the change in the liquid flow rate and the electro-potential of the flow. The periodic nature of changes in flow characteristics is explained by continuous charge formation and charge interaction in the diffuse layer. Periodic charge accumulation and subsequent charge transfer across the channel cross section depending on the charge sign acquired, as well as compression of the diffuse layer with increasing NaCl electrolyte concentration in aqueous solution may be the cause of fluid flow variations. The observed effects may serve as a tool for controlling fluid flow in water-oil-saturated formations and, in particular, injectivity of injection wells by controlling electrical conductivity of water injected into the formation.

Abstract
The temperature dependence of unit cell parameters was studied using high-temperature X-ray diffraction and the coefficient of thermal expansion of SnSe single crystal was determined. Fluorescence spectra of SnSe single crystal grown by the Bridgman-Stockbarger method were examined using a Cary Eclipse spectrophotometer at room temperature in the wavelength range 200–900 nm. When the samples were irradiated by a pulse at a wavelength of 230 nm, the fluorescence spectra exhibited maxima at wavelengths 313.07, 423.03, 458.93, 495.07, and 530.00 nm.

Abstract. In this article, the monographic and scientific publications, the practice of unfair realization of rights by the participants of the process are analyzed based on the analysis of certain international legal acts. First of all, we study the legislative consolidation of procedural dishonesty and its consequences, and the impact of presumptions on the identification of procedural dishonesty facts. Based on attribution to investigative and adversary models, specific problems associated with procedural dishonesty are identified, and conclusions about the ways of unfair realization of rights by the participants of the process are formulated.Key words: process, subjective rights, realization, responsibility, bad faith, abuse.

Currently, special attention is paid to the environmental performance of fuels, because, the ever-increasing quantity of transport leads to an increase in the emission of harmful substances into the atmosphere. In particular, for the introduction of environmentally friendly technologies for the production of diesel fuels, first of all, it is necessary to obtain diesel fuel with a low content of sulfur, nitrogen and polycyclic aromatic compounds, which requires the processes of hydrotreating, hydrocracking and hydrodearomatization are carried out, which require significant economic costs. The presented article considers an alternative process for reducing the content of harmful substances, in particular aromatic compounds in the composition of diesel fuel. The process of dearomatization of the diesel fraction was carried out using N-methylpyrrolidone as an extractant at a ratio of extractant : diesel fraction 2:1 for 6 hours. The physicochemical properties of the dearomatized diesel fraction have been studied. In the resulting dearomatized diesel fraction, the sulfur content decreased to 0.0220%, and the content of aromatic compounds to 0%, in addition, the fractional composition is facilitated, the density and viscosity decrease. In order to replenish the resource of diesel fuel, oxygen-containing additives were added to the dearomatized diesel fraction - butyl esters of fatty acids of sunflower oil in an quantity of 5-10%, and the physicochemical properties of the resulting compounds were studied. It was revealed that the addition of butyl esters of fatty acids of sunflower oil to the composition of the dearomatized diesel fraction favorably affects the quality indicators of the obtained compounds. So, there is an increase in the flash point by 6°C and the cetane number by 4-5 points, and the sulfur content decreases to 0.0198%. In addition, the diameter of the wear scar decreases by about 2 times and for a 5% compound it is 0.430 mm, and for a 10% compound it is 0.370 mm, which meets the modern requirements of the standard. Thus, obtaining environmentally friendly diesel fuel is possible by dearomatization of the diesel fraction with the subsequent addition of butyl esters of fatty acids of sunflower oil, which can be recommended as a multifunctional additive to diesel fuels.
