Published: November 2019

Abstract
The article presents an analysis of the world and Russian production of cucumbers, as one of the most common vegetable crops in many countries, open and closed ground. Among the vegetable crops grown in protected soil, the most profitable is cucumber. The share of each district in the gross harvest of cucumbers closed in Russia is calculated, and the regions with the maximum absolute index are listed. The volume of imports to Russia is shown in terms of value and in kind, indicating the key supplier countries. In recent years, more and more demand in the market is becoming environmentally friendly vegetable products, the cultivation of which is widely used biological remedies. To obtain environmentally friendly products, it is necessary to use plant protection systems based on the use of biological plant protection products and growth regulators, which increase the disease resistance of plants in adverse conditions. To analyze the effectiveness of such means, in the course of research, the effect of the drug Gliocladin in combination with the growth regulator Zircon against the root rot was studied. On the basis of the obtained data, the economic effect of their use in the conditions of film greenhouses is calculated.

Published: November 2019

Abstract
Garden beets are one of the most popular vegetable root crops, which are grown everywhere. The existing commodity production in Russia is not able to provide the population’s need for fresh vegetable products. In this regard, attracting the attention of large farms to the culture of garden beets, as one of the economically viable among the group of garden root crops, is an actual task. In connection with the intensification of agricultural production, the cultivation of single-seeded (single fruit) varieties and hybrids suitable for mechanized cultivation is an important direction in the selection of garden beets. The article provides a comparative analysis of economic efficiency in the cultivation of multi-seeded and single-seeded varieties of breeding of the Federal Scientific Center for Vegetable Growing (Russia). The calculations were carried out on tariffs and prices relevant in 2017. It is proved that in the production of single-breed varieties, the total amount of production costs decreases by 19.4%, compared with the multi-seeded standard variety. The high marketability of the products obtained in the context of lower production costs determines an increase in net income from sales, as a result, the profitability of production increases, which makes it possible to introduce single-fruited varieties in crop rotation without risking profit.
The life cycle and parasitic system of opisthorchis felineus in the Irkutsk opisthorchiasis focus
Authors: Rusinek O T 
Published: November 2019

Abstract
The article for the first time presents generalized data on the parasitic system and the life cycle of Opisthorchis felineus (Plathelminthes: Trematoda) in the Irkutsk center of opisthorchiasis on the river Biryus. The relatively low abundance and contagion of the first (mollusks) and second intermediate hosts (fish) clearly demonstrates that the natural and anthropogenic sources of invasion are very minor here. Human, domestic cats are infected with opistorch. However, because of the actual breaking of the chain, their eggs may not be released into the water due to objective circumstances (remoteness, small number or absence of the first intermediate owners). O. felineus during the implementation of its life cycle in the parasitic system can complete it as an autogenous species, without leaving the aquatic environment and as an allogeneic species, completing the life cycle in land mammals and in humans.

Published: November 2019

Abstract
The article presents a comparative analysis of such an important trait that is economically valuable for vegetative reproduction in the bearded iris as the degree of winter hardiness of rhizomes. Economic efficiency for the industrial production of planting material is also calculated. The degree of winter-hardness was determined by the ratio of the number of plants left before winter to the number of plants that grew up in early spring. As a result of research, 84 varieties of domestic and foreign selection were assessed, among which a total of four groups were identified with varying degrees of winter hardiness. Observations have shown that the irises of domestic breeding and time-tested foreign varieties, which have been cultivated for a long time in central Russia, are most resistant to overwintering. The economic efficiency of growing planting material was 144% per unit area (1 ha).

Published: November 2019

Abstract
The high investment potential of the regions of Siberia is substantially leveled by the low infrastructural potential and the high level of investment risks, primarily social and environmental risks. Consequently, the fundamental basis for ensuring their sustainable development and increasing investment attractiveness is the optimization of social and environmental risks. And the main indicators of their sustainable development are the indicators characterizing the environmental safety and social and environmental risks of the population. To assess the socio-environmental risks of harm to the health of the population of the region, taking into account its specific features, we propose to use data mining methods and neural network models, along with classical methods.

Published: November 2019

Abstract
In this work ultra-high temperature zirconium carbide (ZrC) powders were synthesized using sol-gel method combined with Spark plasma sintering (SPS). It can be concluded that SPS sintering for synthesis powder were both fast and efficient. Grain growth of ZrC particles could be also limited due to the fast heating rate. Temperature over 1700°C will lead to the fast formation of ZrC powder. Pure ZrC powders could be obtained with an grain size of 100-500nm at temperature of 1750°C for 5min. Due to the fast heating/cooling rate, long heat treatment period is significantly reduced and the grain size could be strongly suppressed.

Published: November 2019

Abstract
The mesoporous zirconate powders were synthesized by solvent evaporation using P123 as templates. The phase composition, pore size distribution and thermo-physical properties were tested and analysed in this study. The test results show that the samples have mesoporous structure after removing template by heat treatment. Mesoporous pore size are mainly distributed in the range of 5-50nm, and the pore volume less than 50nm accounts for about 24% of the total. The thermal diffusivity and thermal conductivity of mesoporous (La0.8Yb0.2)2Zr2O7 are lower than common alumina and zirconia materials, and the lowest thermal conductivity is only 0.218W/(m•K).

Authors: Kuang F H , Bao Y W , Zhang H B , Ren J L , Ren R K 
Published: November 2019

Abstract
Ceramics are widely used because of their excellent mechanical properties, electrical insulation properties, high temperature resistance and corrosion resistance. Ceramic plate is one of important branch of ceramic components. However, brittle fracture caused by low toughness and high sensitivity to surface defects limits the reliability of ceramics. Therefore, there are a lot of research on strengthening and reducing defects of ceramic plate. In this work, a pre-stressed ceramic plate was obtained by a simple method, which was impregnated with a layer of alumina slurry on the surface of zirconia substrate and sintered at 1500°C. Because the expansion coefficient of alumina is lower than that of zirconia, a compressive stress is formed on the surface of plate, which can reduce the defect sensitivity and improve the bending strength of ceramic plate. Compared with the pure zirconia plate, the strength was improved with about 40%.

Published: November 2019

Abstract
3D measurements at cell body and the whole surface scales are researched as one of the series of long fiber reinforced woven composites (LFRWCs) multi-scale measurement and evaluation. This paper proposes a method to determine the maximum sampling step (MaxSS) at cell body surface scale and the minimum cell body number (MinCBN) at the whole surface to solve the problem that the measurement results are inaccurate owing to the improper sampling parameters. Three LFRWC surfaces are tested as demonstrations to state the method concretely. The results show that as long as the woven style and the processing angle are confirmed for an LFRWC, the shape and the size of the cell body is constant. At cell body scale, the sampling area is equal to the cell body size, and the MaxSS is about fiber diameter. At the whole surface scale, the proper sampling step should not go beyond the MaxSS at cell body scale, and the MinCBN the sampling area should contain is different for various materials which should be determined based on the practical situation. This research provides a fundament for the precise evaluation of the relation between an LFRWC property and the whole surface topography.

Published: November 2019

Abstract
Short silica fibers are prone to conglomerate in aqueous medium, which means that dispersity and suspension stability show key effect on the uniformity of ceramics with silica fibers as raw materials. In this work, various parameters including pH values, dispersants and dispersing approaches, were systematically studied to investigate the effect of slurry dispersion on properties of thermal insulation materials with silica fibers as matrix. Moreover, the novel composite dispersants were creatively introduced in this work and the corresponding synergetic dispersion mechanism was investigated as well. Fiber slurries with optimized dispersing and suspension properties was obtained when pH values were set as 4, the content of R type dispersant was adjusted to 0.12% and the addition of PEO was fixed at 0.04%. After settling for 360s, no obvious agglomeration could be found. Rigid thermal insulation materials with homogeneous structure and high performance were obtained with conditions mentioned above, which can be expected to further expand the application of short silica fibers.

Published: November 2019

Abstract
In this paper, BNf/SiBON composites were prepared by adding short boron nitride fibers and in-situ inorganic solid state reaction. The relationships among hot-pressing sintering temperature, boron nitride fiber content, density and flexural strength of the composites were studied. The phase composition and microstructure of the composites were also analyzed and characterized. The results show that the bending strength of BNf/SiBON increases with the increase of sintering temperature when the fiber content is constant, and decreases with the increase of fiber content when the sintering temperature is constant. XRD diffraction patterns also showed that BN had higher crystallinity and larger grain size when the sintering temperature was 1700°C and the content of BN fiber was 40%. Therefore, the best content of boron nitride fibers is in the range of 20% to 40%, and the hot pressing sintering temperature is about 1700°C.
