Authors: Yudakhina M A 
Published: January 2020

Abstract
The article is devoted to the problems of maintaining viability and increasing the productivity of honey bees in Eastern Siberia. The benefits of coniferous wormwood extract for autumn-spring feeding of bee colonies are described. The researches have shown that bees more actively took food with coniferous wormwood extract than regular sugar syrup. Feeding bees with syrup with extract positively influenced the course of wintering of bees: in the experimental group there was 100% safety. A positive effect of the extract on the development of bee colonies, flight activity of bees was noted: it was seen that the individuals were strong and active. As a result of the researches, it was noticed that after a six-fold feeding of bees with coniferous wormwood extract, the strength of the bee colonies, the average honey and wax productivity, the number of brood and received nucleus increased. The daily increase of population made it possible to maintain an optimal microclimate in the brood nest. It was found that stimulative feeding with the extract increased resistance to such common diseases as varroatosis (there was an 82.8% reduction in the mite strike of bee colonies), nosematosis and ascospherosis. These observations indicate that bee colonies had a huge army of working bees, the microclimate inside the nest was healthy, and it made the maximum use of forces for further increase of individuals and making products.

Abstract
On the example of a single population of sables of the Pushkin animal farm (Federal state unitary enterprise “Russkiy Sobol”), the heritability of the general coloring of their hairline was studied. In total, puppies of 1,561 female sables of the black sable breed were analyzed with a total score of 4,794 puppies. Based on the results of the study of various color forms of sables, the heritability coefficients (h2) of the black-brown color form were determined as 0.128; dark brown as 0.108 and chestnut as 0.078, which indicates a high selective sampling for darkening the overall color of the hairline in this population.

Published: January 2020

Abstract
Dermatophytosis (ringworm) is the most important infectious and contagious skin disease of cats in shelters. Wherein, the diagnosis, identification and treatment of dermatophytosis is not always effective. Here we report an epidemiological study of the outbreak of feline dermatophytosis in animal shelter in Moscow region. At least 11% of cats kept in the shelter were affected. Seventeen cats suspected dermatophytosis were isolated for mycological examination and treatment, 82% of them were culture-positive. These cats received a course of oral terbinafine, with no topical treatment. Of the dermatophyte-positive cats, 36% demonstrated skin lesions, while 64% were asymptomatic. No mycological control of recovery was carried out after treatment. It was found that 44% of clinically recovered cats turned to be asymptomatic carriers. When examining environmental objects (bedding, cat houses, floors, etc.), dermatophytes were isolated from 80% of the samples. The only causative agent of dermatophytosis was Microsporum canis. The MIC (minimal inhibitory concentration) of terbinafine for clinical strains of M. canis was determined to be 0.001-0.002 μg/ml. The study confirms the need for large-scale mycological screening of cats in shelters using DTM-type diagnostic media. Oral therapy alone is not sufficient for effective treatment; it should include the whole-body antifungal treatment. Mycological control of cure is also mandatory.
Problems of primary seed production of some rice varieties

Published: January 2020

Abstract
Rice is a product that combines high calorie content with dietary and medicinal properties. Its consumption in our country, and throughout the world, is constantly growing. In this connection, the relevance of the need to develop new rice varieties that harmoniously combine high yield and excellent grain and milled rice quality is increasing. The key to obtaining quality rice grain and seed is competent seed production work. This article presents the results of many years of research on the possible causes of the appearance of unusual phenotypes (atypical plants) in the primary seed production nurseries of three new rice varieties, fundamentally different in architectonics - Anait (tall, early ripening and large-grain), Sharm (short, early ripening and long-grain) and Lastochka (medium-grown, medium-ripening, medium-grain). Variety Anahit was found to be of different quality according to grain thickness and the weight of 1000 grains. The range of variation in the grain thickness was 1.2– 2.4 mm, and in the weight of 1000 grains - 33.9–44.4 g. Therefore, all plants of this variety were conditionally grouped into two classes and analyzed in detail by family. In the long-grain variety Sharm, an unusual trait appeared - the spinousness of the grain. In the primary seed production nursery in 2016, out of 600 sown plots, 329 plots had different types of spinousness. It is considered that the set of chromosomes according to spinousness trait in the variety Sharm included both recessive and dominant genes (an1, An2⁕, An3⁕; An1⁕, An2⁕, an3). And in the event of an unfavorable combination of circumstances (abiotic and anthropogenic factors) in 2015, in the phase of heading-flowering in the variety during fertilization, gene unlocking occurred, as a result of which atavistic traits started being observed in the progeny. In variety Lastochka, families significantly differed both among themselves and in the years of cultivation, in resistance to blast and in the mass of 1000 grains. In the process of primary seed production during family-wide selection, families with average resistance to blast and with improved technological milled rice characteristics were identified.

Authors: Ma Hongfeng , Liu Gaojie 
Published: January 2020

Abstract
The supporting force distribution is very important for the vehicle to maintain safety and stability, especially for the heavy-duty refitting vehicle with eccentric load. A simple and generic model to compute the supporting force distribution is essential in the design stage of refitting vehicle, whereas there is little research involving in solving this problem by now. This article presents an efficient and simple method to predict the supporting force of tire (supporting point). Firstly, the model for the vehicle with three or four axles is simplified. The mathematical matrix is established by force equilibrium equation, moment equilibrium equation and deformation compatibility equation. With the known parameters of load, position and dimension, the force of every supporting point can be calculated, and so the supporting force distribution is acquired. Then, a corresponding experiment is designed and implemented. According to the results of the comparison, the results indicate that the general prediction method to calculate supporting force distribution presented in this paper is accurate and validated in the pre-design stage of the refitting vehicle.

Authors: Tao Xigui , Jia Yifan , Fan Chengfei 
Published: January 2020

Abstract
In order to improve the explosion resistance performance of masonry structures during the terrorist attacks and accidental disasters, clay brick and concrete block walls are reinforced by modified polyurea materials. Explosion resistance tests of these two kinds of masonry wall structures are carried out to analyze the failure modes and anti-explosion effects of reinforced masonry walls under different thickness and reinforcement modes. The results show that modified polyurea elastomer not only has good spraying adhesion and compatibility with the base material surface, but also can effectively encapsulate the explosive debris generated by the back blasting surface of the masonry wall under explosive load, which reduces the deformation and displacement of the wall.

Published: January 2020

Abstract
Reactive powder concrete(RPC) is a kind of ultra high performance concrete material, which has ultra high compressive strength and durability as well as good tensile property, elastic modulus, energy absorption and ductility. All these properties make it to be a better choice for the construction of bridges, buildings, military architectures, nuclear structures and the buildings bearing severe environment. The good tensile property, durability and ductility of RPC depend on the steel fibres mixed in the concrete. The bridge effect of steel fibres provides high tensile strength and crack resistant property. The tensile constitutive model of RPC differs from the normal concrete. This study tried to obtain the tensile constitutive model of RPC based on the flexural experiments of RPC prism. On the basis of test results, the tensile constitutive model of RPC is given in this study.

Abstract
With the development of tea production, treating tea waste has become a problem that cannot be ignored. Here, we reprocessed tea waste to create a new kind of biomass material and named it “CHAMU”. We found that tea waste is a good fiber raw material and can improve the degradation rate of PLA composites in the soil. Based on the above findings, we established a tea waste recycling system. During the processing, it was found that tea stems, tea residue had better plasticity than wood-shaving materials. According to this characteristic, we designed a series of “CHAMU products” to explore “CHAMU” materials in product design.

Authors: Liu Linlin , Dong Huajun , Wang Xiaochi , Zhou Chaoyu 
Published: January 2020

Abstract
The crystal morphology and formation of the microstructure of the laser weld of Fe-Mn-Si memory alloy were analyzed by metallographic microscope and scanning electron microscope(SEM) and X-ray diffractometer (XRD). The results show that the welding seam microstructure of Fe-Mn-Si memory alloy crystallizes symmetrically from the fusion zone on both sides to the weld center. The γ→ε martensite transformation occurs in the welding seam and its adjacent tissues due to laser welding. This is because of the residual stress generated in the welding process, and this kind of ϵ martensite transformation and its deformation relaxes the residual stress of the weld, thus affecting the mechanical properties of the weld.
