Research technique and test experiments for the analysis of petrophysical properties of weak-consolidated and friable rocks

With the use of created measuring system for the study of petrophysical properties of incompetent, friable and loose rocks and sludge samples test experiments were performed on pit sand samples of known grain-size distribution, consolidated and disintegrated rock samples of Subbotin oil field of the Maykop formation. It was experimentally established that the shrinkage rate of soft rocks decreases sharply and attenuates at the effective pressure of 30 to 35MPa, which leads to stabilization of their filtration-capacitive and deformation behavior. The research of rocks, which are returned during drilling in the form of sand and cuttings, opens opportunities for using the obtained data for interpretation of production well logging and calculation of hydrocarbon reserves

Noise and Transport Characterization of Single Molecular Break Junctions with Individual Molecule

We studied the noise spectra of molecule-free and molecule-containing mechanically controllable break junctions. Both types of junctions revealed typical 1/ f noise characteristics at different distances between the contacts with square dependence of current noise power spectral density on current. Additional Lorentzian-shape (1/ f 2) noise components were recorded only when nanoelectrodes were bridged by individual 1,4 benzenediamine molecule. The characteristic frequency of the revealed 1/ f 2 noise related to a single bridging molecule correlates with the lock-in current amplitudes. The recorded behavior of Lorentzian-shape noise component as a function of current is interpreted as the manifestation of a dynamic reconfiguration of molecular coupling to the metal electrodes. We propose a phenomenological model that correlates the charge transport via a single molecule with the reconfiguration of its coupling to the metal electrodes. Experimentally obtained results are in good agreement with theoretical ones and indicate that coupling between the molecule metal electrodes is important aspect that should be taken into account.Comment: 15 pages, 7 figure

INSURANCE AS AN EFFECTIVE MECHANISM TO MINIMIZE RISKS AT THE ENTERPRISE

Purpose: The article analyzes the state of domestic insurance in agricultural enterprises, which is a complex type of property insurance, subspecies of which are insurance of crops, animals, commodity aquaculture, real estate and income of agricultural producers. Methodology: Generally accepted methods and techniques of economic research were used in the study process: monographic (in the process of studying risk management theoretical foundations), statistical and economic (when studying trends of AIC enterprise development and functioning), design-constructive (when justifying and calculating indicators of enterprise functioning), abstract and logical (when generalizing conceptual and methodological approaches in identifying, analyzing and assessing risks), comparative analysis (synthesis of native and foreign risk management experience), various risk assessment methodologies. Result: The economic risk passport is understood as a set of information about the risk area, risk criteria, as well as for instructions on the application of the necessary methods to manage or minimize the risk. The article presented a liquidity loss risk passport with one of the measures to minimize it - self-insurance. Applications: This research can be used for universities, teachers, and students. Novelty/Originality: In this research, the model of Insurance as an Effective Mechanism to Minimize Risks at the Enterprise is presented in a comprehensive and complete manner

Identificação de pólos de crescimento a longo prazo como um instrumento fundamental da política federal dos territórios regionais da Rússia

In the current economic situation, in the time of limited resources and opportunities, as well as the number and severity of unresolved social and economic problems, the possibility of using the theory of "growth poles" is increasingly important. Determination of the most promising sectors of development of regions, levels of development of industries contribute to improving the effectiveness of strategic planning of the region, as well as the specific focus of investment activities within the region. Due to the limited budgetary funds in the region, it is necessary to identify unstable industries in the region, as well as the development prospects characteristic of the Belgorod Region, for the implementation of support and regulation. The main results are presented in the given article: the concept of “growth poles” for the region is characterized, and the algorithm for determining promising growth poles is considered using the example of the Belgorod region, the main promising sectors are identified, as well as the level of development of each of the sectors at present.En la situación económica actual, en el tiempo de recursos y oportunidades limitados, así como en el número y la gravedad de los problemas sociales y económicos no resueltos, la posibilidad de utilizar la teoría de los "polos de crecimiento" es cada vez más importante.
