Published: August 2019

To expand the reproduction in the agricultural industry (a priority task of Russia), to achieve the goal of import substitution and food security, it is necessary to ensure continuous renewal and replenishment of resources. To assess the type of reproduction in agricultural organizations, average annual growth indicators taking into account resource (labour, land, capital) and economic conditions (profitability, liquidity, financial stability, turnover) were used. According to the method used for assessing the type of reproduction, organizations can be categorized into three clusters. Development problems within each cluster were determined to evaluate conditions of reproduction taking into account cluster characteristics. Agricultural organizations using the method of expanded reproduction have modern agricultural equipment, high-yielding crop varieties and highly productive animal breeds. Organizations of the second and third clusters have limited resources (labour, land, basic and working capital) and low profits.

Agrophysical properties of black soils depending on types of economic use in the Krasnoyarsk forest-steppe
Authors: Badmaeva S E , Badmaeva Yu V , Semenova V V
Published: August 2019

About 50% of the world’s distribution of the richest soils on the planet, black soil, is concentrated in Russia. On black soil, 75% of the gross output of grain crops and 50% of livestock production are manufactured. However, the current state of black soils causes concerns about the increasing degradation that threatens Russia’s food security. Black soils are a subject to significant anthropogenic stress; first of all they are exposed to agricultural impact. The problem of degradation of arable black soils is largely due to the deterioration of agrophysical properties and the degree of degradation varies in different soil-climatic zones. The granulometric compositions, density of soil structure, general porosity and water permeability depend on the nature of the soil use. Throughout the entire range of the studied agrophysical soils properties, arable black soils are inferior to virgin analogues located in similar conditions of the landscape. Post-irrigative soils transformed into a set aside are inferior in their agrophysical properties to virgin analogue, but surpass arable soils in some indicators. The range of unfavourable properties of black soils acquired as a result of irrigation is quite wide and manifests itself at almost all levels of their structural organization. It should be noted that irrigation with ecologically safe irrigation norms of 300 m3 / ha does not impair the physical properties of the soil, in contrast to heavy irrigation norms, that determine the unidirectional and noticeable expression of the main indicators in the direction of their deterioration.

The work evaluates the cytogenotoxic effect of mercury by performing a primary screening on a plant object. The authors determined the qualitative and quantitative characteristics of a cytogenotoxic effect depending on the exposure time and the dose of mercury nitrate (Hg (NO3)2) in anaphase and telophase of mitosis on wheat apical meristem cells of the Memory of Aziev variety. In the process of primary screening to assess the cytogenotoxic effect of the test substance, the nature and diversity of chromosomal abnormalities in the wheat meristem cells of the presented variety were studied. The frequency of occurrence of various types of chromosomal aberrations was analyzed. The complex shows the effect of mercury salts on viability indices and chromosomal instability of wheat. The cumulative pathology curves for different exposures of (Hg (NO3)2) are presented. A significant increase in the number of pathologies was shown in accordance with the increase in mercury concentration in anaphase of mitosis. A similar pattern was observed in the change in the total number of chromosome aberrations in accordance with the increase in the soaking time of seed material. The results of the study of the cytogenotoxic activity of mercury make it possible to assess the toxicity of mercury (Hg (NO3)2) for plant objects and recommend the object used in the experiment as an adequate model of test systems for studying xenobiotics.

Authors: Lysakov Alexander
Published: August 2019

Modern techniques of potato tubers storage have a number of economic, technical, and technological disadvantages and they don’t ensure high product safety - potato losses run up to 30 % per storage season. The work has been conducted on the effect of magnetic field of neodymium (NdFeB) magnet on sprouting, weight loss and storage of potatoes because this method is the most interesting and understudied. The equipment used in the research: equipment for magnetic potato treatment, NdFeB magnets, magnetometer is used to identify positive and negative magnetic poles, and auxiliary instruments. As a result of the experimental studies it has been found that untreated potatoes had weight loss of 39 %. Weight loss of potatoes treated with positive magnetic field of 330…350 mT and time treatment 60…180 s was 4 %. The positive magnetic field of 330…350 mT was effective in suppressing sprout growth. It is also to inhibit sprout growth in potatoes stored at 25°C. Potatoes receiving more than 330…350 mT dose, were higher in length of sprouts, and higher weight loss of potatoes (20…50 %). Also, potatoes receiving negative magnetic field dose, were higher in length of sprouts, and higher weight loss (60 %) than those given positive magnetic field dose. As a result of experiments, the design of a new device for magnetic processing of potatoes has been developed. It is anticipated that magnetic fields influence the potato cells, as the result of the effects, potato tubers either lock in moisture, starch and other substances, or lose them quickly due to inner-structure destruction.

Optimization of the daily load schedule with the help of energy storage device in order to ensure compliance with the declared tariff price category in the retail electricity market
Authors: Dmitriev A A , Gerasimov V E
Published: August 2019

This paper is devoted to the analysis of electricity consumption by a real enterprise in Western Siberia and the development of recommendations for optimizing its electricity consumption in the context of the tariff policy for the region. The paper discusses the possibility of using energy storage device to reduce the maximum power consumption by organizing charge and discharge cycles of the drive in certain periods of the day. During minimum power consumption, the daily load curve is levelled due to the process of charging the drives. The energy is released into the circuit at the maximum power consumption of the enterprise, reducing its peak load. Aligning the daily schedule of the projected power consumption allows selecting a price category with a lower tariff rate when applying for technological connection. It is concluded that the use of energy storage device for saving for these purposes is unprofitable, since the payback period of the drive significantly exceeds its service life. It is noted that a possible area of application of energy storage device includes enterprises where process violations lead to significant economic damage, the minimization of which justifies the use of expensive energy storage devices.

Published: August 2019

The results of the dependence of the activity of cellulose-decomposing microorganisms on the anthropogenic impact on the soil are presented in the article. The qualitative reaction of microbial community to cellulose was assessed by the decomposition of linen fabric. The decomposition of the textile fibers and the increase of the weight of pieces of linen fabric by 30.64% in samples which were laid at the level of 10-20 cm in favourable soil conditions were demonstrated. It was determined that the highest microbial number was observed when a soil extract was cultivated on the Chapek medium, regardless of the soil conditions in which the microorganisms lived. The soils of the Volgograd region in the sphere of anthropogenic impact are contaminated and poor in micro- and macroelements, so they are not suitable for the life of the soil microbiota. That fact is evidenced by the lack of growth of microorganisms on an agarized soil starvation medium.

Published: August 2019

Creation of highly productive cross-countries, transition to nonconventional power supplies of a bird, sharp restriction of its vital space, constant accumulation of egg and meat efficiency has led to very essential changes in a structure and physical and chemical properties of eggs. It forces scientists and practicians to make certain changes to requirements for quality of incubatory eggs, the modes of their storage and incubation. Influence of preincubatory storage of eggs on deductibility is a subject of long-term researches, but the modern theory doesn’t offer any explanation of contradictory information which we have now. Bird’s egg quickly loses the initial properties therefore can’t maintain long-term having rummaged in development (the latent period) and in several days of storage becomes of little use for an incubation. The researches confirmed that creating conditions close to the natural process occurring in the nest due to the application of short-term heating of eggs during the storage period, can contribute to maintaining high hatchability at its longer storage. In conditions of forced storage, the short-term preheating of hatching egg to the optimum temperature allows to increase chick hatchability by reducing embryonic death and reducing the incubation time.

Authors: Viktorova E V
Published: August 2019

Multipotent mesenchymal stem cells (MMSCs) are potentially promising cells for non-pharmacological therapy. We have carried out a comparative analysis of MMSCs populations isolated from different anatomical areas of canine adipose-derived tissue (subcutaneous and visceral adipose tissue) with different age (one year and ten years) characterized by immunophenotype CD44 + / CD90 + / CD105 + / CD45-. Histochemical analysis revealed that the number of cells in per unit volume of canine adipose tissue decreases with age. The number of cells derived of stromal-vascular fraction by filtration method (filters 80 microns) also revealed the dependence on the age and anatomical location of the collected adipose tissue. In dogs of one year age, the number of cells in this population was 2.4 ≥ times more than in the experimental groups of 10 years. The necessity of collection adipose tissue from dogs of 10 years for further isolation of MMSCs has been justified, compared with dogs aged one year.

The nuclear power station severe accident in Fukushima Daiichi became an important lesson learn to involve the passive cooling system in order to enhance the safety in a nuclear power station when prolonged station blackout occur. A U-shaped heat pipe is proposed as one of alternative passive cooling technology to absorb the decay heat generation in the cooling tank that connected to the reactor cavity cooling system. This research objective is to know the effective thermal conductivity of the U-shaped heat pipe. The effective thermal conductivity is an important factor to know the effect of the U-shaped heat pipe to remove the decay heat generation to the heat sink. An experiment was conducted to know the effective thermal conductivity of U-shaped heat pipe. The air cooling velocities on a bonded-fin heat sink in the condenser section were used as a parameter to obtain the effective thermal conductivity of U-shaped heat pipe. The air cooling velocities were varied at 0.65, 0.74, 1.02, and 1.21 m/s. The experiment results showed that the effective thermal conductivity of 35.37 was obtained at the highest variation of air cooling velocity on a bonded-fin heat sink in the condenser section. The result obtained shows that U-shaped heat pipe as a heat transfer device has thermal conductivity 35.37 times greater than the solid U-shaped Copper with the same geometry and dimension. This investigation results can be used to justify the use of heat pipes as a good passive cooling system in cooling tanks connected to Reaktor Daya Eksperimen reactor cavity cooling system.

Monitoring of the dc resistance value of a multiproduct calibrator had been implemented. This multiproduct calibrator is commonly used as a reference standard to calibrate electrical measurement testers such as insulation tester, earth tester, continuity tester, ground bond resistance tester and many other resistance meters. The monitored value of the multiproduct calibrator can be used to support measurement traceability needs for those electrical measurement testers and meters in a power distribution utility. The monitoring was done by measuring nine data of resistance value within nine respective days to constructa preliminary statistical control limits. The measurement was continued monthly to monitor the dc resistance value that was intended to test the control limits. The monitoring is performed by doing F-test and T-test on the recent measurement data over the all previous measurement data. If a measurement data is found to be outside the control limits, an action should be done to accommodate the information and renew the statistical control limits. The renewal action for the dc resistance value of the observed multiproduct calibrator was performed for several times within a year. It is reported based on the method implementation acquired within a year, that the upper control limit (UCL) and the lower control limit (LCL) for the dc resistance value of 19 kΩ is 18.99964 kΩ and 18.99912 kΩ. Moreover, to verify the performance of the final statistical control limits, the additional measurement is taken and the result lies between the UCL and LCL

The aim of this study is to investigate and analyze the NdFeB N52 type magnetic field distribution on a Trapezoidal type coil in an axial type generator. The main problems addressed by this study are how the distribution of magnetic field type NdFeB N52 to the trapezoidal type coil and how the influence of air gap between NdFeB N52 magnets and the coil to the output electric voltage generated from the coil at the speed of rotation. In order to answer the problems, we moved a rectangular type magnet axially towards the trapezoidal type coil with a specified distance, so that we could identify the change of the output voltage. The description of the magnetic field distribution in the stator was simulated by using the Maxwell 3D Design application ran in ANSYS software 16.0. The result of this study shows that the magnet was distributed evenly on the coil. It is also known that based on experiments with 2mm to 6mm of magnet to coils of gaps, the highest output voltage is at 2mm gaps at 750rpm.

Chitosan:SiO2 nanocomposite (Cs:SiO2 NCs) is synthesized via aerosol processing. Ultrasonic spray drying apparatus was used to produce smaller sized composite particles with spherical morphology. Composite from shrimp shell and water glass (Na2SiO3) as silica precursor were used for the preparation. Cs:SiO2 NCs were characterized by Fourier Transform Infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) to know about the chemical bonding and morphology of the particles, respectively. Based on the FTIR investigation the absorption peak at 1090 cm−1 represents the reaction of silanol groups of silica with carbonyl groups of polymers leading to the formation of Si-O-C bonds. The morphology of Cs:SiO2 NCs was more spherical than chitosan particles with relatively narrow size distribution. The smaller particle size of Cs:SiO2 NCs is potentially applied to engineer the material for drug delivery system.

Published: August 2019

The spectral-luminescence characteristics of binuclear bis(BODIPY) complexes in cyclohexane and ethanol, which exhibit different photophysical and photochemical properties in these solvents, have been investigated. It has been shown that the difference in spectroscopic properties is due to intermolecular interaction of the excited molecules with solvation shell. The possibilities of practical use are discussed.

In this paper we synthesized high entropy oxide system (Sc0.2Ce0.2Pr0.2Gd0.2Ho0.2)2O3±δ by precipitation of hydroxides from REE nitrates aqueous solutions and annealing the mixture at 800 °C. It is possible to obtain the various forms of simple and complex composition based on the rare earth oxides, including oxides in the form of nanosized powders. The main idea of obtaining HEOS comes from the field of high-entropy alloys. The interconnection between configurational entropy and mixing enthalpy is a key factor for determining phase transformations. The phase composition, structure, and surface morphology of the obtained powders were investigated by scanning electron microscopy and X-ray phase analysis methods.

Published: August 2019

Composites based on a porous hydroxyapatite carcass with a coating of PLGA were obtained. According to the SEM images, it was found that, the composites had a different coating character depending on the porosity of the HA framework. After 1 week, the dissolution rate of composites increases relative to pure PLGA, and the growth is proportional to the increasing of the amount of pore-forming agent in the material by 20-50%. The dissolution rate of HA in the composition of materials also increases since the second week, because the diffusion of the solvent in the HA increases as the result of PLGA hydrolysis.

Nowadays air and water pollutions are becoming a serious problem for urban environment. One of the efficient methods of purifying water and air is photocatalysis on TiO2 films. In this work, we obtained composite materials based on TiO2 and modified by Ag and SiO2 on the surface of the fiberglass material (Ag/SiO2/TiO2/FGM) by a sol-gel method. Complex studies were carried out to identify the phase compositions, morphology and textural characteristics of obtained samples by X-ray diffractometey, scanning electron microscopy, micro-X-ray spectral analyses and analysis of N2 adsorption-desorption isoterms. Surface area and average pore size of this sample is 8.2 m2/g and 11.4 nm respectively. Prepared composite Ag(0.5%)/SiO2(3%)/TiO2/FGM material revealed photocatalytic activity in model reaction of methyl orange azo dye photodegradation under UV-irradiation.

The urgency of creating new efficient catalysts for the processes of deepening oil refining rises on the background of stricter requirements for the quality of motor fuels, as well as the deterioration of the quality of crude oil for processing, and an increase in the number of distillates of secondary processes involved in the production of commodity petroleum products. In this work, alumina-catalytic systems were synthesized using polyoxomolybdate compounds. The morphology, structure and phase composition of the synthesized catalytic systems were studied using the following analysis methods: scanning electron microscopy, microelement analysis, X-ray phase analysis, X-ray diffraction, electron spectroscopy. It has been established that the Mo / AI2O3 system is active in the process of thermal catalytic conversion of heavy residual raw materials.

Published: August 2019

The paper presents the results of studies of rheological properties of the initial viscous solutions of polyvinyl alcohol and ‘oil-in-water’ (O/W) emulsions. It is found that aqueous solutions of polymer and polymer-based colloidal systems have typical non-Newtonian properties. After the freeze-thaw cycle, the viscous liquid systems pass into a solid state of aggregation to form multicomponent cryogels with rubber-like structure. The elastic properties of two-component cryogels consisting of polyvinyl alcohol and water only, three-component compositions formed on the basis of an ‘aqueous PVA solution-mineral oil’ emulsion, and cryogels containing loose dispersed fillers are investigated. The physicochemical properties of the obtained elastic samples are studied. The prospects of application of cryogels for the oil producing well and road construction are outlined. A comparative analysis of physicomechanical properties of cryogels depending on the nature of the filler is carried out. In order to simulate the real conditions of oil field construction in the permafrost zone, samples of cryogels with solid dispersed fillers pre-wetted with oil are prepared and their mechanical and hydrophobic properties are investigated. Hydrophobic properties of cryogels make it possible to use them as waterproofing layer (membrane) in the construction of the asphalt pavement and insulation of the bottoms and walls of hydraulic structures. Cryogels can be recommended for use as polymer ‘pigs’ for removal of undesirable deposits in the pipeline during its cleaning or for pipeline pressure testing. In this case, ‘batching pigs’ are introduced to the boundary between hydrocarbon liquid and water.

Published: August 2019

The paper considers alternative methods of activation of cement systems based on the use of internal properties of cement. Their peculiarity is the use of activated cement and changing the sequence of mixing of cement mortar. Mixing of the main volume of Portland cement with cement slurry and its prior curing for 15 minutes allowed increasing the strength characteristics of hardened cement paste. As shown by experimental studies, the strength of the samples increases by 10–30% depending on the method of preparation and curing time of the cement slurry. Further experiments will be aimed at researching “activated cement–activated water” system.
