Published: December 2019

Abstract
Sumatran yew (Taxus sumatrana) tree contain taxane diterpenoid, an effective anti-cancer drug. Taxus population in the world is declining due to overexploitation. Study on habitat characteristic of T. sumatrana was conducted in Kerinci Seblat National Park. Twenty four Plots of 20 x 20 m were laid purposively in the habitat of T. Sumatrana to determine the structure and composition of the vegetation. At each plot data on the physical component such as land slope, air temperature and humidity were also measured. Soil samples were taken around T. sumatrana trees at 4 different depths i.e. 0-10 cm, 10-20 cm, 20-40 cm, and 40-60 cm and brought to a soil laboratory for physical and chemical properties analysis. The result showed that T. sumatrana occupied a middle canopy stratum and the trees were easily found, however at sapling level was rare and the seedling level was not present at the plots. T. sumatrana commonly grows to clump at a steep slope, high humidity, and cold temperature. The soil at the habitat of T. sumatrana is porous and fertile.

Abstract
The research aimed at resolving the issues of utilizing the tailings as fertilizer is presented. The aggregate for the machine utilization of after harvesting tailings as fertilizer is described. This machine is designed to work on straw, from which it selects plant material and grinds it while simultaneously treating with a process solution of agents. The solution accelerates the decomposition process, and then the machine evenly distributes fertilizer ready for use with the possibility of simultaneous incorporation into the soil (depending on the traction class of the tractor used). The introduction of the process solution is carried out by fine spraying through centrifugal nozzles mounted on the nozzle ramp behind the distribution flaps. Four biological agents for the preparation of a process solution accelerating the decomposition of the tailings are considered: Agrinos 1, Sternifag, Ekorost and BTU Biocomplex. The results regarding influence of the tested agents on the decomposition rate of after harvest residues are obtained. The unit proposed for recycling the tailings as fertilizer has passed operational tests during the experiment. The power reserve in terms of the volume of the technological tank was 3000 ± 20 m, which provides 4 driving strokes, with an average bout length about 700 meters for the Ryazan region. Thus, refueling of technological tank is carried out on one side of the field. Measuring the operating speed showed it was 6-8.5 km/h for different bout lengths and evenness of the field, the hourly output was 5-5.5 ha/h.

Published: December 2019

Abstract
The problem of the rational hole location on the surface of a thin-walled cylindrical gravity tank was studied in order to minimize the stresses around the concentrator. The studies were carried out for three cylindrical tanks with internal diameters of 250, 400 and 500 mm, respectively, with a height of 500 mm and a wall thickness of 20 mm. The diameter of the hole in the tank wall was varied as follows: 6, 10, 14, 18, 20, 23, 25, 30, 32, 36, 40, 45, and 50 mm. The holes were located on the lateral cylindrical surface of the tank, with the following variation of the location heights in relation to the total length of the cylinder element: 4/8, 3/8, 2/8, 1/8, 1/16, 1/32. As a result, it was determined that the increase of the internal diameter of a cylindrical tank increases the equivalent stress around the concentrator. Within some ranges, a change in the diameters of the hole does not actually affect the stress pattern. Using the holes of certain diameters can reduce the stresses around the concentrator.

Authors: Gerber J , Zavaly A , Gavrilov A , Olshevskaya A , Kiyan N 
Published: December 2019

Abstract
The paper is devoted to the study of the processes of heat and mass exchange, when drying ferrocene containing wastes of winemaking (FWW), and to the preparation of those wastes to be fed to dairy cattle. The goals of the article are: to determine the amount of energy costs for drying FWW that are necessary for calculating the net cost of feed additives, and to estimate the economic efficiency of the suggested technological and technical solutions; and also to justify and develop the methods for estimating quantitative parameters when removing liquid from the wastes of wine production. Moisture and heat exchange are studied in the “heat agent - drying object” system for convective and infrared drying. A combined method is proposed for drying winemaking waste, to substantiate the sequence of stages and parameters of the process, a graph-analytic model, that is dwelled on the basic principles of convective and infrared drying, is designed. Numerical calculations helped to obtain graphical dependences of the energy costs of the drying process on the air velocity in the drying chamber at different temperatures of the air (for convective and infrared). The model of drying in the form of comparative graphical dependences of the reduced value of the drying speed to the heat flux on the moisture content of the mass subjected to drying is presented. Given the above data, it is recommended to use combined two-phase drying: in the first phase, use infrared radiation, when in the second phase - convective way, in order to reduce the humidity of ferrocene containing winemaking wastes from initial moisture content of 80% to the required value of 18-20% with the further use as neutralizing additives in the feed of dairy cattle. It is also suggested to use the renewable energy sources for heating in order to cut the expenses in the phase of convective drying.

Abstract
The study is devoted to the improvement of the technology of fruit flavored wines. The paper presents the results of the physicochemical composition study of apple, pear and honeysuckle juices obtained from the raw materials of the Siberian assortment on suitability for the preparation of flavored wines. Samples of varietal (apple, pear, honeysuckle) and blended (apple-honeysuckle, pear-honeysuckle) flavored wines are prepared. A comparative assessment of product samples according to the physico-chemical composition and organoleptic properties of varietal and blended wine materials and wines was made. It is determined that blending apple and pear juice with a combination of honeysuckle one has a positive effect on the biochemical assessment of the drink. Thanks to this technology, obtained samples of blended wines are enriched with polyphenolic substances and vitamins. Aromatization was carried out by joint fermentation of juices with spicy aromatic raw materials, which ensures the enrichment of wines with biologically active substances. In the process of the physicochemical parameter analyzing, an increase in the values of the titrated acidity without deterioration of the finished product taste was noted. The obtained samples of blended wines are differed in organoleptic characteristics -the flavor is characterized by an original taste with honeysuckle notes and a pleasant aroma. Preparation of blended flavored wines by the proposed technology allows expanding the range of wine products.

Published: December 2019

Abstract
Yersinia ruckeri was first discharged from carp brood fishes (Cyprinus carpio) farmed in ponds in southern Russia. The death of fish was observed at a temperature of 15°C in March-April 2015. Ten fish with clinical signs of the disease were taken for research. Water samples were taken for hydrochemical analysis. The research results indicated a high level of permanganate index (2.4–2.8 MAC), nitrite nitrogen (1.5–2 MAC), nitrate nitrogen (1.4–1.5 MAC), and a low oxygen content in the bottom layers (2.0 mg/dm3). A parasitological study of fish revealed an invasion by monogenes (Dactylogyrus extensus) and mollusks (Unio pinctorum). As a result of bacteriological studies, 62 isolates were discharged, 30 from water and 32 from fish. The determination of bacteria was carried out according to morphological and enzymatic properties. The biochemical characteristics of the Yersinia ruckeri strains made it possible to classify them as serotype 1. All Yersinia ruckeri strains were sensitive to ciprofloxacin, tetracycline, chloramphenicol and resistant to furazolidone. MALDI TOF mass spectrometry and PCR were used for additional identification of bacteria. Serious pathological and histopathological changes in the fish tissues were not detected.

Abstract
The central problem of the use of LEDs in greenhouse production is the establishment of a causal relationship between the environment in a parametric microclimate and the manifested properties of a biological object (phenological, biological, spectral sensitivity). Information management systems with biofeedback relate to biotechnical systems in which a biological object directly participates in the formation of control decisions in real time. At the same time, the plant as a biological object detects a feedback channel from the source, which indicates the external plant characteristics (phenomenological and spectral characteristics, intensity of such processes as photosynthesis, respiration, transpiration, etc.).

Published: December 2019

Abstract
The article discusses the situation with the restoration of the machine and tractor fleet of agricultural enterprises in the Samara region and determines the role of individual elements of the economic mechanism. In modern conditions, the main guarantee of the success of agricultural production is the maximum mechanization of production processes. Replacement of manual labor by machine allows reducing the cost of production, increasing its output, implementing modern industrial technologies, reducing the dependence of the result on the human factor. The purpose of this study is to determine the capabilities of agricultural enterprises in the Samara region to modernize the composition of the equipment used. The number of almost all types of energy and agricultural machinery compared with the 1995 level has decreased significantly. At the same time, energy supply per 100 hectares of arable land has stabilized, which is explained by the choice of powerful, productive equipment. The situation can be corrected by increasing the profitability of crop production and correcting the situation with price disparity. Direct government funding for acquisitions has declined. Among the instruments of state support, along with interest rate subsidies, subsidization of expenses for the purchase of cars has been widely used. The amount of subsidies reaches 492.2 million rubles (2013). The applied measures of state support in the conditions of the Samara region are complex and, with prolonged use, can solve the problem of updating equipment.

Published: December 2019

Abstract
The paper is devoted to summarizing the experience of forming sources of funding in emerging markets and analyzing the efficiency of capital use using the example of agricultural enterprises in the South of Russia. The literature review covers studies revealing the determinants of the formation of sources of capital funding in both developed and emerging markets. It is noted that the features of the establishment of business structures and the country’s financial system are factors in the choice of hierarchy theory by the management of companies in the formation of capital structure. A study of the impact of the weighted average cost of capital on return on assets was carried out using the example of agricultural enterprises in the South of Russia. The obtained results confirm the developed hypotheses about the negative impact of an increase in the volume of debt financing of agribusiness organizations on the return on assets, as well as about the choice of a conservative agricultural policy by agricultural organizations in forming funding sources. These results are close to the results of applied research on the formation of capital structure in other sectors of the Russian economy.

Published: December 2019

Abstract
The object of the research of the presented article is the internal axisymmetric cylindrical flanging. This work is intended to improve the quality and accelerate the development of technology for flanging round holes from sheet blanks and designing tooling by improving the accuracy of calculating the diameter of the flanging holes in the automated mode for constructing three-dimensional models of a blank and a flanged product. Formulas are proposed that increase the accuracy of calculating the diameter of the hole for flanging. The accuracy of calculating the diameter of the flange hole according to the proposed formulas is determined by comparing the mass of the workpiece with the mass of the flanged part. The algorithm for the automated construction of a sketch of a flanged part and the determination of technological parameters is implemented in KOMPAS-3D. The constructed models allow making changes to their parameters and to provide automatic presentation of the calculation results, as well as their correct graphical interpretation. A discussion of the results of the work allows drawing conclusions about the correctness of the proposed mathematical model and its applicability to the automated construction of three-dimensional models of flanged parts, which will simplify the development of technological and design documentation with a simultaneous increase in their accuracy and reduce the cost of preparing the production.
