    A complex of technical solutions is presented which makes it possible to study the influence of external factors on changes in the indicator of fat acidity value (FAV) and a range of other parameters characterizing the quality of preservation of long-term stored wheat grains in South Russia. Storage conditions (natural climatic, model) and also the effect of dust suppression treatment of grain by oil glazing that is carried out in some grain terminals in the South of Russia were taken as controlled external factors. New data has been obtained on changes in parameters of food suitability of the wheat grains during storage under model conditions with varying degrees of severity of climatic conditions in South Russia. After 6 months of storage the most considerable changes in FAV value were found for 4th class of wheat stored in natural climatic conditions with intensive insolation, the increase was 1.7 mg KOH/1 g of fat (from 7.3 mg KOH/1 g of fat up to 9.0 mg KOH/ 1g of fat). Minimum changes in the same parameter for the same storage period were observed for the wheat of the 3rd class stored in a thermostat at a stable high temperature of 35 ΒΊΠ‘ (from 11.6 mg KOH/1 g of fat to 11.5 mg KOH/1 g of fat). For wheat of the 4th class, the changes were 0.7 mg KOH/1 g of fat (from 7.8 mg KOH/1 g fat to 8.5 mg KOH/1 g of fat). Analyzes of stored wheat grains subjected to dust suppression by the oil glazing showed similar results, which allows us to state the absence of a significant effect of oil glazing on changes in wheat properties during its storage.Based on the results of the experimental analysis and a generalization of the data obtained an assumption was made on the possible reasons for the lack of pronounced trends in the data for the expected increase of FAV value in food suitability of the wheat grain when it is stored under typical model conditions of South Russia. The likely reason for this is the corresponding moisture state of grain, the water activity of grain was about 0.45. Such a low value was due, in particular, to the fact that samples of model-stored grain had a limited volume and do not reproduce the mass transfer processes that involve deep layers of the grain mass (because of the mass absence), which takes place during storage of grain in an industrial environment. The tools were proposed for the operational monitoring of the moisture state of wheat grain during storage. Moreover, a plan has been developed to expand the field of modelling storage processes in terms of varying the moisture state of the stored wheat grain samples with an assessment of the influence of moisture state on the dynamics of changes in the parameters to be controlled.A complex of technical solutions is presented which makes it possible to study the influence of external factors on changes in the indicator of fat acidity value (FAV) and a range of other parameters characterizing the quality of preservation of long-term stored wheat grains in South Russia.

    A review of systems of forced control with buster and holding windings is carried out. It is found that there is a large number of various systems of forced control of electromagnets. It has been established that in the contactors systems of forced control with buster and holding windings are most often used. The advantages and disadvantages of such systems of forced control are considered. It has been discovered that the most commonly used forced control device for monostable electromagnets consists of two coils with two windings: buster (B) and holding (H), and a normally closed contact of the auxiliary contact block, as well as a diode rectifier, a diode and a capacitor. Such a device is widely used by many leading manufacturers of vacuum contactors such as: ABB, Siemens, Alstom (Areva), Schneider Electric, Eaton, Electrodynamics, etc. Experimental studies of transients in one of the switching devices - the vacuum contactor in which this device is used, namely, the serial three-pole vacuum contactor ΠšΠ’Π’Π½-250/1,14 produced by Electrodynamics Company are carried out. Two series of experiments were conducted: the first series of experiments was conducted for the existing system of forced control, and the second series of experiments - for a forced control system in which the diode was shortened, the anode and cathode of which were connected with the ends of the retaining windings, respectively, of the first and the second coils of the electromagnet. The research was carried out using a digital two-beam oscilloscope SIGLENT SDS1052. The oscillograms of current and voltage in the buster and holding windings are obtained at various voltage values U = 220, 180, 150 V, and when powered from a source of constant voltage, and then from a source of alternating voltage. The analysis of experimental research is carried out. The advantages and disadvantages of the forced control device are revealed. It is revealed that the switching device (vacuum contactor ΠšΠ’Π’Π½-250/1,14) will not operate at an unacceptable voltage drop, which will lead to overheating of the coil, and it will fail. The conclusions are made and possibilities of perfection of the forced control device for monostable electromagnets are shown.ΠŸΡ€ΠΎΠ²Π΅Π΄Π΅Π½ ΠΎΠ±Π·ΠΎΡ€ систСм форсированного управлСния с пусковыми ΠΈ ΡƒΠ΄Π΅Ρ€ΠΆΠΈΠ²Π°ΡŽΡ‰ΠΈΠΌΠΈ ΠΎΠ±ΠΌΠΎΡ‚ΠΊΠ°ΠΌΠΈ.

    Expression of Toll-like receptors in emotiogenic structures of rat brain is changed under longterm alcohol consumption and ethanol withdrawal

    Recent studies have provided strong evidence that long-term ethanol consumption leads to activation the mechanisms of neuroimmune signaling. Recently, much attention has been focused on the study of toll-like receptors (Toll-like receptors, TLRs), which play one of the key roles in the mechanisms of activation of the innate immune system in brain structures subsequently ethanol consumption. It is known that the activation of TLRs leads to the release of many proinflammatory cytokines with the resulting neuroinflammatory process. There are suggestions that TLRs may also be involved in the modulation of neurotransmitter systems of the brain, thereby contributing to the formation of pathological dependence on ethanol. The goal of our work was to study the level of expression the genes of TLRs (TLR3, TLR4, TLR7) and pro-inflammatory cytokine genes (IL-1Ξ², CCL2) in the rat brain (amygdala, hippocampus, medial entorhinal cortex, striatum) under conditions of prolonged alcoholization and on different periods of alcohol withdrawal, which was previously not studied by researchers. Prolonged alcoholization of rats with ethanol did not lead to changes in levels mRNA of TLRs in the studied structures of the rat brain, with the exception of a small increase in the level of TLR3 mRNA in the hippocampus of prolonged alcoholized rats and a slight increase in the level of TLR3 mRNA in mEC. However, gene expression of TLRs undergoes changes in all the structures of the rat brain studied by us at different periods of alcohol withdrawal. The increased level of expression of both TLRs and proinflammatory genes in the period of alcohol withdrawal in the rat brain hippocampus deserves special attention, which indicates the presence of a persistent neuroinflammatory process in this brain structure in the period of alcohol withdrawal, which is probably supported with the participation of TLR-dependent signaling. The study of the mechanisms of inflammatory process activation by TLR-dependent signaling in different brain structures can open new targets for drug exposure. Such drugs can be used in the treatment of alcoholism
