Description
This article describes the practice of conducting a geotechnical monitoring of the road tunnel № № 8, 8а «Doubler Kurortnogo Prospekta» in Sochi in difficult geotechnical conditions. Geotechnical monitoring method was developed on the results of mathematical modeling performed based on engineering studies and design solutions. The particular importance is paid to areas of shallow road tunnels, because in these areas there are the highest strain that could lead to malfunction of the lithological technical system "accommodating array - fixing tunnel" and the further destruction of the road tunnel walling. Geotechnical monitoring at the stage of engineering survey allows us to assess comprehensively the condition of the geological environment in a pristine condition, as well as detailed consideration to the effect on her of construction of mining operations. Implementation of geotechnical monitoring at the stages the engineering survey and construction will identify weaknesses malfunction of the lithological technical system "accommodating array - fixing tunnel" and ensure the security of the operation of such a technically complex and demanding facilities such as road tunnels

Description
The results of the study of amino acids of white table wines depending on the yeast strain, continuous contact of wine with yeast biomass and the presence of lees stirring are presented. The dynamics of amino acids, which affect wine organoleptic characteristics and the formation of wine defects, specifically, tyrosine, methionine, threonine and lysine is shown. Conducted researches made it possible to divide the amino acids into three groups depending on the carrying out the batonnage or lack of it. The first group consisted of amino acids, the concentration of which practically has not changed in the presence or lack of stirring. The second and third groups include amino acids, the concentration of which increased and decreased, respectively during batonnage. The stirring of the wine with yeast biomass facilitated to the activation of mass transfer processes between cell and medium, and the access of air lead to oxidation of some amino acids and the change of its concentration. The absence of stirring influenced to a slight increase in the concentration of such amino acids as cystine, cysteine, β-phenylalanine, serine, α-alanine, leucine and glutamic acid. The experimental data allowed to arrange amino acids in a row depending on the speed of release into the medium: ά-aminobutyric acid > glutamic acid > α-alanine > leucine

Description
Nowadays some branches of the industry need hybrid or cascade systems of electric drives. Electric drives use up to 60 percent of all developed electric power therefore with improvement of massdimensional indicators and power characteristics of the considered devices necessary technical characteristics are reached and losses of electric energy decrease. When creating electric drives of various designs, it is important and rather difficult to calculate an electromagnetic system. Classical approach to design of data of systems has a number of shortcomings that demands creation of new approaches or adjustment and addition of the known methods and approaches. In the article, another approach to design of the developed systems of the electric drive is offered

Description
The modern level of development of the industry requires creation of more difficult and high-precision systems of an electric actuator allowing executing precisely and correctly the given technological processes. As these devices, we may consider hybrid or cascade systems of an electric actuator. However, for creation of such devices we require new design approaches, or specification and improving of the existing theories and methods of design of classical systems. The main difficulty in calculation consists in determination of parameters of electromagnetic system. In this article, new approach is given in finding of electromagnetic parameters of components of an asynchronous controlled cascade electric actuator taking into account real geometry. This approach was formed during creation of the program complex, which is a part of a system of automatic design

Description
In Nigeria, belt of bituminous sand stretches to the East of Ijebu-Ode (Ogun State) in the district of Siluko and Akotogbo, Okitipupa (Ondo Sate) and Edo State. It covers a distance of approximately 110 km and lies in the upper cretaceous sequence of the Abeokuta formation in the eastern Dahomey Basin. Reserves of bituminous sand in Nigeria is estimated to be around 30- 40 billion barrels with a possibility to extract 3654 × 106 barrels. From the approximately 30-40 billion barrels of oil sand, Ogun State has more than 40% in reserve. However, this huge stock of oil sand in Nigeria is yet to be exploited. This article provides an assessment of technological solutions for the design and development of tar sand fields in Nigeria. Reserves of oil sand in Nigeria are the biggest in the whole of Africa

Description
This article cites the data about the amount and productive capacity of oil producing enterprises in the Russian Federation on the whole, as well as in Krasnodar region and the Republic of Adygeya. It is shown, that innovations in the field of waste disposal and waste recycling left after oil production are the most effective, as they contribute to the cost reduction on disposal of waste on landfill and thus, improve environment considerably. They also provide additional revenue from the sale of new products, received after waste recycling. The authors examined literature data on compositional and chemical analysis of waste left after cleaning main oil-bearing crops, processed by oil-producing industry of the Russian Federation (such as sunflower, rape, soy-beans) . The analysis of available technologies of their disposal, such as waste incineration, pyrolysis, worm composting, landfilling, biothermal composting, granulationa of waste and the processing of undersow is submitted to your attention. The analysis of advantages and disadvantages of all available technologies was carried out, and it was noticed that neither of available technologies had become common use. The most prospective direction for the development of efficient technology of waste recycling has been chosen, which includes the use of waste pressing after their rational preparation and isolation of uniform and valuable components. It is shown, that the primary task for the development of such technology is the study of waste composition of raw materials and industrial cleaning of sunflower seeds, soy-beans, and modern sorts of rape and its hybrids

In the article, we present the analysis and improvement of existing methodologies for assessing the intelligence factor, taking into account its use of the Internet on a regular basis. Today, the use of the Internet in our daily activities and tasks become practice that is more common. The Internet has become a popular and most frequently used means of obtaining information quickly and in large volume. The authors suggested the presence of the Internet and its impact on the everyday use of psychological and intellectual life of the people that can be recorded because of user IQ scores. It is suggested here also gets its development in the search for and analysis of system models, allowing determining the numerical values of the parameters. Specifically, it is proposed to use a large variety of statistical data to clarify the unknown parameters that determine the levels of human intelligence, taking into account the impact of the Internet. These statistics include information such as the number of people with higher education, the number of Internet users, the degree of the Internet penetration in society, the most typical tasks that use the Internet users, and others. For the processing and analysis of the test statistics in the work proposed to use tools data mining, ie, data mining. We have also considered the most typical approaches Data mining, applied in similar research areas. We have analyzed what specific principles and methods can best approach to solving the problems of intelligence assessment indicators. The result of the article was a number of conclusions, in particular, the feasibility of applying clustering to analyze data in the field. Also, in certain cases, we provided the use of Kohonen neural network in the vector quantization network format. Methods: analysis of scientific literature and online sources of information on the current level in the field of IQ research; modeling; Methods systematization (tabular calculations and compilation); Experiment (real human test data). Methodological bases of research: a systematic approach (considering IQ in the form of a functional multi-component dependencies), probabilistic and statistical approach (provides guidance for constructing mathematical models linking together IQ and the influence exerted on it using the Internet, and to assess the reliability of a computer program ) qualimetric approach (determines the need multicriterion diagnostic influence of factors on the level of intelligence)
