MODELING OF GEOTECHNICAL BARRIER IN WEAK CLAY SOILS ARRANGED TO PROTECT EXISTING BUILDINGS FROM IMPACT OF NEW CONSTRUCTION

abstract 1311707128 issue 131 pp. 1556 – 1570 29.09.2017 ru 292
To reduce the development of additional settlement strip foundations of the existing building on the effect of pressure transmitted to a ground base located near the new slab foundation is considered the work of the geotechnical barrier in various ground conditions. In the first variant of soil, conditions (variant 1) made geotechnical barrier structure in a homogeneous thickness of the weak clay soil. In the second variant of soil conditions (variant 2), a separating barrier is performed in a two-layer base. The upper base layer (carrying) is shown a weak water-saturated clay soil, and the second (underlying) - low compressible soil (sandy loam plastic). According to the results of the calculations and modeling found that, the greatest positive effect on the separating barrier structure (geotechnical barrier) is achieved in the case when the base is a two-layer. The lower part of the geotechnical barrier must be recessed into the soil of low compressibility. Additional settlement strip foundation of the existing building in a uniform basis (variant 1) in the absence of geotechnical barrier is approximately 8 cm. In the case of a two-layer base (variant 2), the additional settlement strip foundation building is reduced by 80-85% (6.6 cm) and will make about 1.4 cm

Analysis of rice market in the country was conducted, as well as assortment of rice products was studied. It is shown that rice is the most popular grain in Russian Federation and in percentage of cereal products in shops they occupy 29% and in diet of Russian people – 41%. It is found that in Russia round grain japonica varieties are the most popular kind. It is mentioned that for the last years consumer market demands diversity of rice products, including long-grain and exclusive varieties, imported from abroad. It is shown that in big cities demand for such products has increased from 5% to 15%. Analysis of milled rice balance was conducted. It is found that volume of milled rice in the domestic market of the country is annually about 680-800 thousand tons exceeding the average demand value by 54,8 to 172,3 thousand tons. Promising breeding directions are observed for increasing assortment of rice products in Russian markets with a view to import substitution. It is mentione that Russian breeders have developed group of exclusive varieties: Rubin, Mars, Viola, Violetta, Avstral, Ivushka, Natasha, Aromir etc. It is shown that special purpose varieties currently occupy 3,5% of rice acreage in the Krasnodar region and their cost is by 20-70% higher than that of traditional rice varieties. It was found that for their implementation into production and promotion on the consumer market we need to develop agricultural techniques of cultivation and seed production scheme in accordance with the biological characteristics, conduct marketing activities, promotion of a healthy diet

TO THE 100TH ANNIVERSARY OF THE GREAT OCTOBER REVOLUTION: THIS ETERNAL LAND QUESTION ...

abstract 1321708096 issue 132 pp. 1199 – 1216 31.10.2017 ru 289
The relevance of the causes, results and consequences study of the October Revolution in Russia is shown. The problems of modern land relations are formulated. It is concluded that one of the main reasons for the October Revolution was the unresolved land issue, which remains unresolved during the modern economic reform. The centennial anniversary of the Great Russian Revolution is an occasion to comprehend the whole complexity of land relations, to see the solution of modern land problems in the historical retrospect. The goals and objectives are formulated, the prerequisites, main provisions and results of the Russian reforms of 1861, including the Stolypin reform, are considered, the historical stages in the formation of the land property institute in Russia are shown. The organizational and economic mechanism for implementing the basic land reforms is analyzed. The mechanism included the elaboration of the main redemption operation plan provisions, the resettlement policy in newly developed areas, the activities of the Peasant Land Bank, land management. The main socio-economic results of the reforms are given. It is concluded that the Russian reforms were carried out by decision "from above," they were not completely consistent, the issue of the land ownership was not finally resolved. The reasons for the Russian peasantry active participation in the Great October Revolution are formulated: the centuries-old peasants lack of rights and oppression, their personal and economic dependence on the landlord, serfdom, lack of property, heavy redemption of the 1861 reform obligations and delay of the Stolypin reform; and on the other hand - promised will and land by the Bolsheviks. The views on the revolution results belonging to well-known economists, historians, writers are given. To create a great Russia, the expediency of country's socio-economic development in the only evolutionary way is justified, based on a clearly developed strategy

METHODS OF CHOOSING DIAGNOSED VEHICLE PARAMETERS IN AGRICULTURE

abstract 1171603052 issue 117 pp. 796 – 809 31.03.2016 ru 288
The article presents an analysis of the existing approach to automobiles technical maintenance in agriculture. We have pointed out that in modern conditions it is impossible to forecast the automobiles maintenance operation frequency and as a result its improvement as well. It is obvious that one cannot achieve the considerable increase of maintenance operation efficiency by separate means and there exist the necessity to treat it as a system and use the up-to-date methods to investigate and improve complicated systems. We have made a conclusion that the increase of maintenance operation efficiency is not possible without some rational strategy of maintenance operation and repair. We have shown that the program of maintenance operation and repair being an integral part of automobiles technical maintenance has considerable effect on maintenance and repair quality. As a result, there is some necessity of the developed system of parameters diagnosing and control in technical maintenance and repair. We have shown that to get sufficient diagnose information one needs selection of the controlled parameters which give maximum information about the object technical status taking into account possible characteristics of its operational faults. We have discovered that in order to solve the task it is necessary to have the object’s information pattern, calculation of possible characteristics of the controlled object being in good or bad order due to some parts fault, evaluation of information brought by every parameter and determining parameters to be diagnosed. We have proposed to evaluate the parameters’ information value with the help of information entropy as uncertainty measure that is one of the main concepts of the information theory. Because of solving the task, we have got the aggregate of the controlled automobile parameters orderable according to the amount of information

THE EFFECT OF DRIP IRRIGATION ON SOIL PHYSICAL AND CHEMICAL PROPERTY CHANGE

abstract 1291705085 issue 129 pp. 1172 – 1182 31.05.2017 ru 288
Soil profiles were made in intensive apple orchard in the agricultural enterprises in Lipetsk and Tambov regions in 2015. Drip irrigation in year rates of 500-550 m3 was carried out since 2010. During the research we determined the soil density, the solid phase density, aggregate composition, particle size distribution, the content of hydrolyzable nitrogen and humus by conventional methods. As a result of drip irrigation can increase dust-like fraction in dark gray forest soil, whereas in chernozems this index did not change significantly. In the black earth soil was noted the process of increasing the proportion of mud fraction due to mineral part chernozem destruction. In both soil types was increased sand content. It was found that drip irrigation improves some of the soil water-physical properties, such as a soil structure coefficient and the content of agronomical valuable aggregates in a layer of 20-40 cm. There was also noted that with increasing soil depth was reduced humus and hydrolyzable nitrogen content. In aggregate analysis, it was found that dark-gray forest soil the amount of water-stable aggregates increased, while meadow chernozem leached soil decreased. Data of the aggregate analysis revealed that in the dark-gray forest soil the amount of water-stable aggregates increased as a result of drip irrigation, while in meadow chernozem leached soil decreased. It recommends by drip irrigation application permanent monitoring of the soil humus content
