Using authentic video to develop dialogical discourse skills in foreign language
Higher education

Authors: Sofia O. DAMINOVA graduated from People’s Friendship University in 1995. She is Ph.D. in Chemistry (1999), Senior Lecturer of the Department of Modern Languages of Gubkin Russian State University of Oil and Gas, Senior Lecturer of the Department of English Language of the Faculty of Chemistry at Lomonosov Moscow State University. She is an expert in the theory and methods of teaching English, author of about 20 publications. E-mail: sofiya16s@yahoo.co.uk

Abstract: The paper first describes the method of phased development of dialogical discourse skills in a foreign language using authentic video films. The method is designed for the students of non-philological undergraduate schools and is developed in accordance with modern methodological and didactic principles. The course ware is based on the methodical potential of still images and scenes that are used as types of visual and semantic supports for the development different kinds of skills of dialogical speech (conversation, questioning, discussion, consultation, debate, exchange of information). It is shown that teaching dialogical discourse skills can be based on different types of audio/video texts functioning in the movie: monologues; dialogues; monologues and dialogues (mixed type).

Methodology of separate on-site geophysical monitoring of jointly operated oil reservoirs
Petroleum geology, geophysics

Authors: Sergey I. MELNIKOV was born in 1989. He is graduate student of the Department of Geophysical Information Systems of Gubkin Russian State University of Oil and Gas. His interests of research include hydrodynamic and down hole well logging, information technology in the field of control of field development. He is author of 13 publications. E-mail: s_melnikov@bk.ru

Abstract: This article analyzes the information capacity of hydrodynamic and on-site monitoring of wells drilled for combined development of multi zone oil reservoirs. A numerical model was used to evaluate the reliability and limits of applicability of standard methods of determining separately the reservoir parameters (based on the measurement of zone rates of production). The approximate formulas for the calculation of the individual characteristics of zones based on a priori information about the relationship of skin factors or permeabilities are obtained. A new method for assessing skin factors for the conditions of tapping up at least one operating zone by hydraulic fracturing (HF) is proposed. The method is based on the analysis of the change rate history of the zones production rates immediately after turning the well into production. The proposed methods have been tested using the results of surveys of the pumping wells of «Gazprom Neft» JSC.

Abstract: Operation of concrete composite structures and hydraulic structures in the arctic conditions has specific features. The type of frost resistant concrete is of particular significance in the harsh climatic conditions. Durability of concrete in the arctic conditions depends on the annual number of cycles of freezing and thawing. This paper proposes a new approach to the choice of the properties of concrete structures designed for operating in harsh environments. This is based on statistical processing of the temperature variations and can greatly simplify the procedure for determining the safety factors for strength and deformability.

Abstract: The article investigates the distribution of elastic vibrations in perforated wells to optimize the geometric parameters of the well and the wave mode stimulation. The stand and technique for experimental studies are described. The results of experimental investigation of the propagation of energy fluctuations in the perforated well casing, which allows identifying features of forced vibrations in the well and well casing elements are generalized. In order to provide resonant vibrations of maximum amplitude and reduce energy losses desired geometric characteristics of the well are determined.

Abstract: Due to the stringent requirements imposed on diesel fuel, the authors of this paper proposed a method to improve environmental and performance properties of diesel fuels. The paper presents the results of the study of naturally occurring glycerides as detergent-dispersant additives for diesel fuels. The authors have developed a rapid method of determining the effectiveness of antioxidant additives for fuels and lubricants, which is based on the measurement of the optical density of the sample during oxidation in the given experimental conditions. A rapid method of evaluating the detergent-dispersant properties of the fuel based on the determination of the changes of optical density during sedimentation of the pollutant model based on colloidal graphite of grade P-1 (1 wt. % strong). The results showed that the designed additive shows unique surfactant properties at concentrations of 0,001–0,005 % by weight. The additive improves both thermal-oxidative, detergent-dispersant and environmental performance of fuels, because additive molecules contain optimally combined functional groups which creates internal synergies.

Abstract: One of the problems of gas wells with layers of sands and unconsolidated rocks is the destruction of the near-wellbore zone of the producing formation and sand entry that leads to the formation of sand plugs and declining productivity. Installing filters is not always feasible and cost effective, so in order to increase productivity and reduce costs for well maintenance and workover it is advisable to stabilize the well-bore zone formation by chemical methods. This paper considers the technology of stabilizing the near-wellbore formation zone with the help of the composition based on organosilicone polymer. The results of laboratory studies and the mechanism of adhesion of the resin to the rock are described.

Abstract: To check the adequacy of mathematical models created to simulate asymmetrical failures on the inputs of the synchronous motor and recording of instantaneous values of phase currents, voltages and current excitation a stand was crea- ted. A series of experiments to study the effects of asymmetrical modes on the performance of synchronous motor was conducted. The adequacy is confirmed experimentally.
