Abstract
Biological remediation is the final stage of soil remediation. It is carried out to reduce and prevent the effects of technological disturbances. Plants can uptake and transform heavy metals, inorganic anions, oil products and pesticides. Recommendations were based on the practice experience and scientific researches. The quantitative chemical analysis of the soil pollutants demonstrated the presence of cations of heavy metals and oil products, and a rather high content of chlorides and sulfates was also detected. Such soils should be considered as saline. Therefore, plants for remediation should: a) correspond to the natural and climatic zone; b) show resistance to pollutants; c) plants must be salt tolerant. The composition consists of the following herbs. Medicago x varia Martyn is promising for areas with extreme environmental conditions. Agropyron tenerum Vasey is a good plant for phytoremediation of oil-sludge-contaminated soil. Festuca pratensis is well in universal, road, construction, sports lawns, and for special purposed lawns. Dactylis glomerata decreases gaseous mercury emission to the atmosphere and mercury mobility in soils. Phleum pratense have high phytostabilization potential in polluted soils and adaptation to soil pollution by this metals. That mixture is resistant for contaminated soils.

Published: January 2020

Abstract
The use of local raw materials in the mixed fodder formulations for broiler chickens, including non-traditional raw materials, allows to expand the range of manufactured feeds possessing high nutritional properties and biological value. In order to improve the quality and to reduce the production costs of the mixed fodder due to the cheap raw materials use and the reduction of the premix use share, the mixed fodder formulation for broiler chickens was developed. The nutritional and energy value, safety of mixed fodder are determined. It is established that the nutritional and energy value of the mixed fodder with extruded mixture of non-crushed wheat, peat and cones meets the requirements of the current standard for complete feed for poultry and is obtained in accordance with the rules of the production technological process organization and supervision in the mixed fodder industry. The obtained mixed fodder with the use of non-traditional additives is non-toxic. There is no pathogenic microflora. Replacement of the expensive premix with peat, cones and introduction of non-crushed wheat grain into the mixture before extrusion helps to reduce the cost of finished products. In the production of extrudate from non-crushed wheat (98.8 %), peat (0.6 %) and cones (0.6 %), grinding and mixing with other components of the mixed fodder, the proportion of premix P5-1 decreased to 0.52%. The mixed fodder quality improvement is due to the enrichment with vitamins, essential amino acids and vegetable protein by adding cones and peat.

Authors: Naumov V D , Kamennyh N L , Lebedev A V , Gemonov A V , Gemonova P S 
Published: January 2020

Abstract
In large cities, soil pollution occurs with heavy metals. Forest stands react to environmental pollution by a decrease in growth and an increase in mortality. A typical object for the city of Moscow is the Timiryazev Academy Forest Experimental District. A comparison of the content of gross forms with the clark content of trace elements in the soil profile revealed a significant excess for the following chemical elements: copper, zinc, lead, arsenic. The content of chromium, nickel, vanadium is lower than the clark content. Comparison of the content of gross forms of trace elements with maximum permissible concentrations showed that the content of nickel, vanadium, cobalt is lower than the maximum permissible concentration. The distribution of the gross forms of the elements along the soil profile is heterogeneous. The maximum content in the profile of sod-podzolic soils falls on the humus horizon, which is associated with the biogenic accumulation of these elements.

Published: January 2020

Abstract
The aim of the study was to determine and compare the antiradical and antibacterial activity of the Boletus edulis basidiomycetes growing in different climatic zones: the temperate continental Mediterranean (Montenegro) and sharply continental eastern Siberia (Russia). The objects of study were ceps (Boletus edulis) collected in Montenegro (Durmitor National Park, harvested in August 2019) and in Russia (Siberia, Abansky district, harvested in August 2019). Mushrooms dried and crushed to a powder state were used to obtain aqueous extracts (water module 1:100). The antiradical activity of aqueous cept extracts was studied by UV and visible spectroscopy using a stable model radical of 2,2-diphenyl-1-picrylhydrazyl. For antiradical activity studies, samples were taken after 30, 60, 90 min of extraction. Antibacterial activity was evaluated by the difference in the diameter of the colonies of the test bacteria Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus 209p and Acinetobacter baumannii. It was shown that under the same conditions for sample preparation and analysis, Siberian ceps have a high antiradical activity value (the maximum value is 75% for mushrooms from Siberia against the maximum value of 33% for mushrooms from Montenegro, respectively). The results of the evaluation of antibacterial activity showed that regardless of the climatic zone of the growth of mushrooms, their aqueous extracts obtained after 30 minutes of extraction exhibit bacteriostatic effect in relation to all strains of bacteria. Longer extraction (more than 60 min) leads to the stimulating effect of Boletus edulis extracts on the growth of the same bacteria.

Published: January 2020

Abstract
Honey bees perform 80-95% of all pollination work. Among many species of pollinating insects, honey bees are the main ones in pollination of plants. Bees live in families consisting of many thousands of individuals. They are adapted to highly specialized food, consuming only two main types of food - nectar and pollen, collecting them from the flowers of plants. Bees not only collect food for themselves, but also process it for long-term storage, protect it from enemies and pests, and regulate its consumption in summer and winter. Families of bees can live and breed in the hollows of trees without human influence. It is necessary to change the strategy and tactics of combating quarantine diseases of bees. The most favorable for medical and recreational activities is the autumn period and the beginning of wintering. During this period, in the natural focus, the mechanisms of transmission of pathogens and their distribution are reduced to a minimum, except for the transmission of pathogens through food (honey, candi). But it is possible to eliminate. Work with bee families in winter is possible, does not adversely affect their livelihoods. Currently, work is underway at the Federal State Budgetary Scientific Institution of the Federal Research Center of the Physics and Power Engineering Institute of the Russian Academy of Sciences on the treatment of quarantine diseases of bees. Considering that the epizootic process does not stop under the conditions of quarantine of bee diseases, we propose to ensure strict isolation of infected bee families during treatment, which significantly increases the effect of veterinary measures in the treatment of quarantine bee diseases using artificial feed with medical preparations in the summer. This article discusses aspects of the epizootic process in quarantine bee diseases. On the example of bee varroosis, a strategy and tactics for combating quarantine bee diseases are proposed.

Abstract
The evolution of microsturcture and mechanical properties of ZYK530 Magnesium alloy during extrusion and die forging compound forming process were studied and analyzed. The results show that the as-cast ZYK530 alloy mainly consists of a-Mg matrix and I-Mg3Zn6Y and a small amount of W-Mg3Y2Zn3 and Mg2Zn3 phases. During extrusion to die forging forming, the grain size of as-cast ZYK530 Magnesium alloy is refined and uniform under the action of three-dimensional compressive stress and high temperature deformation. The I-Mg3Zn6Y phase of ZYK530 magnesium alloy decrease relatively, while the distribution of W-Mg3Y2Zn3 is more obvious, a small amount of Z-Mg12ZnY and Mg-Zn phases and undetermined phases can be observed in the matrix. Tensile test results show that the tensile strength, yield strength and elongation of extruded preformed specimens are increase by 32.6%, 18% and 18% respectively compared with as-cast specimens. The mechanical properties of final forged specimens are improved by 9%, 38.6% and 23% respectively compared with those of extruded preformed specimens. The fracture mechanism changes form as-cast cleavage fracture to mixed fracture mechanism of toughness and brittleness.
