The need to specify the types and forms of communication between the subjects of the educational process in the university is becoming acute. In the current situation and the challenges to institutions of higher education, among them - requirements for quality of training, a change in the students, the competition of universities, the implementation of the educational process in the new, rapidly changing environment; acquiring new personal current practices underutilized in education. This practice is network communication. The universality of interaction, the multiplicity, the diversity of levels, the extreme complexity of representation, put forward problems becomes important. Today, in the social world, interaction acquires special, new characteristics due to the specifics of the interacting forces. And above all, when the bearer of these forces is the person himself, the social subject acting and projecting his own actions. The research studies consider the technologies of interaction of students at different stages of professional development. Therefore, the problem of involving students in new educational and social practices on the basis of network interaction resources – resources used in everyday life-is becoming more relevant. To build an individual trajectory of professional development in the Samara region, an information and communication system "Student and Trud" is being developed, which will become a resource for networking between students and leading enterprises of the Samara region.

Microgreens are a new functional food crop that can facilitate adaptation to urbanization and global climate change, and improve human health. The research was carried out in 2021 at the Department of Landscape Architecture of the Kuzbass State Agricultural Academy. The aim of the research was to study the technology of cultivation of microgreens of the Brassicaceae family on an aqueous substrate. The objects of research were the seeds of cultivated plants of the Brassicaceae family: Brassica oleracea Broccoli Group broccoli or asparagus, Fortuna, Raphanus sativus radish, Violetta, Lepidium sativum, watercress, Dansky, and Eruca versicaria, arugula, Sicily. It was revealed that microgreens can be obtained from seeds of the Brassicaceae family in 6-12 days. Such a product does not have time to accumulate harmful substances from the atmosphere in a short period of time. When growing microgreens, it is not necessary to use mineral fertilizers, pesticides and, thus, it is possible to obtain environmentally friendly, biologically useful products with low material costs. It was found that, depending on the seeds of the studied crops and their genotype, the cycle of growing microgreens lasts from 6 to 10 days after germination. Depending on the type of culture, the sprouts reached a height of 5-10 cm. The laboratory germination rate was 96-98%.

The paper presents the data on the use of percutaneous electrical spinal cord stimulation in patients in the acute period of rehabilitation treatment after ischemic stroke. It was revealed that inclusion of percutaneous electrostimulation of the spinal cord into the rehabilitation program improves the quality of motor skills recovery and can be used in the correction of locomotor functions during rehabilitation after ischemic stroke. Key words: ischemic stroke, percutaneous electrical spinal cord stimulation.

The effect of percutaneous electrical stimulation of the spinal cord on the reactions of the autonomic nervous system in patients after acute cerebral circulatory disorders was evaluated. Patients in the acute period of rehabilitation treatment underwent a course of percutaneous electrical stimulation for 10 days. Before and after rehabilitation, vegetative reactions were assessed using an orthoclinostatic test, an A.M.Wein questionnaire, and neurological disorders on the Scandinavian scale. The inclusion of the course of percutaneous electrical stimulation in the program of physical rehabilitation of patients who have suffered an ischemic stroke indicates an improvement in the motor status of patients and a decrease in the imbalance of sympathetic and parasympathetic influences Keywords: ischemic stroke, percutaneous electrical stimulation of the spinal cord, vegetative reactions

The patterns reflecting the influence of controlling technological parameters on the characteristics of the carburized layer during vacuum carburizing of 12Kh2N4A-Sh and 20Kh3MVF-Sh steels are considered. The need is shown to take into account the presence or absence of active carbide-forming elements in the composition of carburizing steels when developing of vacuum carburizing modes.

Summary Oil field development in the northern Caspian Sea involves the drilling of horizontal wells in terrigenous Lower Cretaceous sediments with low hydraulic fracture pressure, where both geological and technical conditions increase the risk of fluid loss. The main geological factors that cause losses on the Filanovsky and Korchagin fields are wells with direction to maximum horizontal stress azimuth, fractures and faults, and depletion of producing formations. Technical reasons include high mud density, use of standard (without increased diameter) casing, poor borehole cleaning, which leads to unacceptable growth of equivalent circulating mud density during drilling. Separately, the high probability of losses during the cementing phase of the well is considered. One of the proactive tools for managing drilling fluid loss risk is building a geomechanical model that includes calculation of losses and hydraulic fracturing gradients, which allows determining safe limits of equivalent circulating density during drilling and performing trajectory optimization at the initial planning stage to expand the safe drilling fluid density window.

В статье представлены данные применения препаратов, содержащих лизоцим и гаммааминомасляную кислоту (ГАМК), на телятах с целью повышения продуктивности и профилактики заболеваний. Лизоцим и ГАМК выбраны в связи с тем, что телята в большей степени подвержены влиянию стрессов, что негативно сказывается на их развитии и продуктивности. Данные по применению ГАМК свидетельствуют об увеличении среднесуточных приростов на 911,1 за счет повышения стрессоустойчивости, что отражается на большем потреблении корма, снижении случаев заболеваний. Использование лизоцима позволяет повысить иммунитет телят, что положительно сказывается на их продуктивности. Свойства лизоцима и ГАМК позволяют совместно использовать их для повышения стрессоустойчивости и улучшения иммунитета телят.The article presents data on the use of feed additives containing lysozyme and gammaaminobutyric acid (GABA) on calves to increase productivity and prevent disease. Lysozyme and GABA were chosen as calves are more susceptible to stress, which negatively affects their development. Data on the use of GABA indicate an increase in average daily growth by 911.1 since stress resistance increases, for this reason calves eat more feed and fewer cases of disease. The use of lysozyme can increase the immunity of calves, which positively affects their productivity. Lysozyme and GABA can be used together to increase stress resistance and improve calf immunity.

До сих пор многие исследователи не признают материалы устной истории как источник, указывая на их эмоциональную насыщенность и субъективность, следовательно, и нерепрезентативность, недооценивают их актуальность для исторической науки либо не выделяют их в отдельный вид источников. В данной статье предпринята попытка найти место устного исторического источника, созданного методом интервьюирования участников и очевидцев изучаемых событий, в системе источниковых классификаций, существующих на протяжении XX столетия; проанализировать отношение к подобного рода документам ведущих отечественных источниковедов. Особое внимание уделяется характеристике особенностей устных воспоминаний как исторических источников. Автор приходит к выводу: анализ классификаций источников в отечественном источниковедении показывает, во-первых, неоднозначное отношение к устному историческому источнику у специалистов из-за его особенностей. Во-вторых, данная ситуация в исторической науке позволяет предложить расширение существующей группы документов личного происхождения выделением в самостоятельный вид устного исторического источника.DOI 10.14258/izvasu(2017)2-32

Effect of consequent deuterium irradiation on hydrogen trapping is also studied. Influence of such deposition parameters as deposition rate, residual gas pressure, hydrogen pressure, plasma ions energy, substrate material on hydrogen trapping is discussed. A conclusion about trapping mechanism in growing carbon layers is made.

Transalkylation of naphthalene and biphenyl with p -diisopropylbenzene has been studied over Y, Beta, mordenite and ZSM-12 zeolites. The main products of naphthalene or biphenyl interaction with p -diisopropylbenzene were mono- and diisopropylsubstituted naphthalenes or biphenyls, cumene and benzene. Polyalkylated binuclear aromatic compounds were observed only in small amounts. Among the zeolites studied, Beta catalyst was the most active, while mordenite showed the highest shape selectivity towards β,β′-diisopropylnaphthalenes and p , p ′-diisopropylbiphenyls. Dealumination of mordenite led to the creation of a secondary micro/mesopore structure, providing for easier transport of the alkylaromatic compounds inside the pores and higher acid sites accessibility. Both factors led to a significant improvement of the catalytic activity, stability and selectivity. The highest conversions of naphthalene (78%) and biphenyl (57%) were obtained over mordenite dealuminated by calcination at 750 °C followed by leaching with methanesulfonic acid, while the highest selectivities to β,β′-diisopropylnaphthalene (90%) and 4,4′-diisopropylbiphenyl (79%) were observed over calcined mordenite treated with oxalic acid.

A comparative estimation of the frequencies of genetic disorders induced in germ cells of male mice by a single or long-term exposure to incorporated 137Cs or to externa γ-radiation has been carried out. The frequencies of dominant lethal mutations induced by a single exposure were similar with both types of radiation. In stem cell spermatogonia the frequency of reciprocal translocations was significantly lower in the case of single 137 Cs administration than upon external γ-radiation. Upon long-term administration the genetic efficiencies of both types of radiation were similar.

International audience; Micro/mesoporous composite materials with different levels of micro- and mesoporosity were prepared by recrystallization of mordenite in the presence of cethyltrimethylammonium bromide. The materials were characterized by XRD, TEM, IR spectroscopy, nitrogen adsorption-desorption and NH3-TPD. The results highlight that recrystallization in mild condition results in the creation of mesopores in the zeolite crystals and their coating with thin films of mesoporous material. The increase of the degree of recrystallization leads first to the formation of composite materials MOR/MCM-41 and then to a complete transformation of mordenite in MCM-41, followed by a gradual decrease of the amount and strength of acid sites. Recrystallized materials display remarkably high activity, stability and selectivity in alkylation of naphthalene with cyclohexene. The effect is due to the improved accessibility of active sites and easier transport of bulky molecules provided by mesopores. The best catalytic performance is achieved on composite materials with intermediate degree of recrystallization. The yield of alkylnaphthalenes over these materials reaches 80%, while the yield of monoalkylnaphthalenes is up to 58%.

Momentum spectra of protons emitted at angles of 0.103, 0.139 and 0.157 rad in fragmentation of 9 GeV/ c deuterons on 1 H, 2 H and 12 C nuclei have been measured at the JINR synchrophasotron by using a magnetic spectrometer. It is found that the shape of the high-momentum parts of the spectra is defined only by the deuteron structure and the mechanism of deuteron-nucleon interaction and does not depend on a target. The contributions to the differential cross section of the 1 H(d, p)X reaction have been determined, which are conditioned by elastic and inelastic scatterings of deuteron nucleons on a proton, stripping, their interference, and also the excitation of the pion degrees of freedom. In the framework of the light front dynamics, calculations of the proton spectra with the deuteron structure functions for the Paris, Reid soft core, and Bonn potentials have been performed; a better agreement with the experiment is achieved with the deuteron wave function for the Paris potential. A conclusion is made that the nucleons in a deuteron keep their individuality up to relative motion momenta of ∼ 1 GeV/ c .

The deformation theory of dilating geological materials is based on the non-associated law of plasticity. One of its drawbacks is the difficulty to find localization bands and strong discontinuities, at which stress and displacement fields are changing. Corresponding jump conditions are formulated. Examples of solutions are given (shear band in a plane plastic flow, radial flow of material out of an axisymmetric silo).

The paper presents the results of the experiments CAPMOSpsila05 and CAPMOSpsila07 performed on an offshore oceanographic platform in the Black Sea. The platform equipped with contact and remote sensors is located approximately 600 m to the south of Crimea coast, Ukraine. The experiments aimed at air-sea interaction monitoring were carried out by an international research team during summer months in 2005 and 2007. Spectral parameters of wind and waves were estimated from direct and remote measurements. A comparison with known spectrum models was performed.

Micro/mesoporous composite materials with different contribution of micro- and mesoporosity were prepared by recrystallization of mordenite. The materials were characterized by XRD, IR spectroscopy, nitrogen adsorption — desorption and TPD NH3. Catalytic properties were studied in transalkylation of biphenyl (BP) with para-diisopropylbenzene (p-DIPB) and cracking of 1,3,5-triisopropylbenzene (TIPB). Composite materials showed remarkably high activity, stability and selectivity with respect to both pure microporous and pure mesoporous materials. The effect is due to high zeolitic acidity combined with improved accessibility of active sites and transport of bulky molecules provided by mesopores.

The time, polarization and spectral characteristics of the LIS-2 pulsed laboratory synchroton, with an electron orbit radius of 6 cm and a maximum electron energy of 60 MeV, have been investigated. The measured optical characteristics of the synchrotron radiation agree with those proposed theoretically. The results suggest that in the process of acceleration the electrons in a bunch can create bound states.

The proton spectra resulting from 6.3 GeV/ c deuteron break-up on 1 H, 2 H, C, Al and Bi nuclei were measured at an angle of 103 mr (lab) in the momentum interval from 2.6 to 3.6 GeV/ c . The measurements were made at the JINR synchrophasotron with a one-arm magnetic spectrometer on-line with a computer. The results, apart from the effects of pion production, are reasonably reproduced in the framework of the Glauber multiple scattering model, taking into account the relativistic deformation of the deuteron wave function.

The experimental data on d-d collisions at 4.3, 6.3 and 8.9 GeV/ c , exhibiting the two-peak structure in the high-momentum parts of the secondary deuteron spectra at momentum transfers | t | ≈ 0.4–0.8 (GeV/ c ) 2 , are presented. An analysis of the results in terms of the multiple nucleon-nucleon scattering model is given. Some conclusions about the mechanism of the elastic and quasielastic d-d scattering at the above-mentioned momentum transfers are made.

Using a magnetic spectrometer a comparative study was made of the energy spectra of π+ and π− -mesons produced in free pp-collisions as well as in pp- and pn-collisions in deutrons and in carbon nuclei at 654 MeV. The forms of the spectra of pions from deuterium and carbon are found to differ due to: a) a larger extent of correlation of nucleons in carbon nuclei than in deuterons; b) differences in the momentum distributions of nucleons in these nuclei; c) secondary pion-nucleon interactions in carbon nuclei. At ≈ 90° in the centre-of-mass system of two colliding nucleons the ratio of the differential cross sections for the production of π+-mesons on free protons and on protons in deuterons and in carbon nuclei was found to be equal to d σ d ω [ p + p →π + ] H : d σ d ω [ p + p →π + ] D : d σ d ω [ p + p →π + ] C = 1:0.79:0.40 , whereas the yields of π− -mesons per neutron for deuterium and carbon were found to be equal. The measured ratio (dσ+/dω)/(dσ−/dω) of the differential cross sections for the production of positive and negative pions on deuterium and carbon is equal to 10.3±1.3 and 6.0±0.8, respectively. The decrease of the value of this ratio for carbon is caused by a considerable contribution of the secondary exchange interaction π0+ n → π−+p to the yield of π− -mesons.

Two series of composite micro/mesoporous materials with different contributions of micro- and mesoporosity were prepared by dealumination and recrystallization of mordenite zeolite. The materials were characterized by X-ray diffraction, infrared spectroscopy, 27Al magic angle spinning (MAS) NMR, nitrogen adsorption–desorption, and temperature-programmed desorption of ammonia (TPD NH3). Catalytic properties were studied in transalkylation of biphenyl with diisopropylbenzene. Both types of composite materials showed remarkably high activity, stability, and selectivity toward formation of di-isopropylbiphenyls with respect to both pure microporous and mesoporous materials. The effect is due to high zeolitic acidity combined with improved accessibility of active sites and transport of bulky molecules provided by mesopores.

Computer calculations of the spectra of the first and second derivatives of synchrotron radiation (SR) with respect to the magnetic field, the energy and the rate of electron rotation in the orbit have been carried out. A general regularity - the displacement of the maxima of the spectra of derivatives towards the blue with respect to the spectra of stationary SR - has been established and a number of other peculiarities revealed.
