In practice, in the performance of engineering and geological surveys anisotropy of soil strength is often considered not fully. One of the main problems in modeling the stability of rock landslide is an objective consideration of the influence of the parameters of cracks and other surface section on the calculation results. On the one hand, the study of fracture is always a certain measurement error, on the other, that the strength against cracking, in many cases, will determine the stability of the rock mass. It appears that the most promising approach is the simulation of fracture using the anisotropy of soil strength calculations of rock landslides. The article considers the influence of the anisotropy of the strength of the slope of the array of soil on the results of quantitative assessment of the overall stability of the slope. Strength criteria are considered grounds for taking account of anisotropy, the limitations of existing approaches to quantify the stability of slopes, describes the principles of probabilistic analysis in the analysis of the anisotropy of the strength properties of the soil. The possibility of obtaining estimates of probability of landslide deformation, which can then be used in geological risk analysis. © 2017 The Authors.

The results of a study in 1995 showed that about 70 percent of economic sanctions that have lasted morethan 3 years have failed in the achievement of predetermined objectives in changing the behavior or political system in the target country. Then in 1997, a study was conducted that evaluated the effectiveness of economic sanctions about 34%. On the other hand, in terms of the objectives of sanctions, the sanctions are usually imposed for two main purposes: Punitive sanctions to change the behavior of governments (tactical sanctions), and comprehensive sanctions to change the political system or ruling government in the target country (strategic sanctions). This paper tries to supplement the 1995study by Van Bergeijk and Van Marrewijk to analyze the correlation between "the sanctions success "and "the sanctions duration ", and examine the hypothesis that these two variables have always had a negative correlation over the history of economic sanctions since World War II to the present time, and only two of the 13 cases of strategic economic sanctions have been successful (about 15%). Finally, with combination of these two hypotheses, it is concluded that long-term strategic sanctions are very likely doomed to failure. This approach can be used for strategic economic planning of Russia that is target of western strategic sanctions. © IEOM Society International. © IEOM Society International.

The Red Sea Rift has been an object of comprehensive studies by several generations of geologists and geophysicists. Many publications and open-file reports provide insights into the geological history of this rift. Paleogene and Cretaceous rocks, which are considered to be prerift, are locally exposed at the margins of the Red Sea Rift. At the same time, some evidence indicates that at least some of these rocks are related to the early stage of the evolution of the Red Sea Rift. The available geological data suggest that the Red Sea region started its active evolution in the Cretaceous. As follows from lithostratigraphic data, the Cretaceous-Paleogene trough that predated the Oligocene-Quaternary rift covered this region completely or partially. The pre-Oligocene magmatism and geological evidence show that the Cretaceous-Paleogene trough was of the rift type. The Cretaceous-Eocene and Oligocene-Quaternary phases of rifting were separated by an epoch of uplifting and denudation documented by the erosion surface and unconformity. © 2010 Pleiades Publishing, Ltd.

The report focuses on the results of simulation of the near-well area heating by an electric current and the substantiation of using an electric field as a thermal method of oil production intensification. We give the description of such programs as NKAR (the program of the numerical solution of the direct problem of electrical logging), THERM3C (the program of solving the direct three-dimensional problem of thermometry) which were used in the simulation.

The theory of resistivity logging (RL) originally stems from the Fock–Stefãnescu forward problem solution for the stationary electric field E in a piecewise homogeneous isotropic medium, with a single boundary corresponding to the surface of a cylinder unlimited by height. The cylinder simulates a borehole filled with drilling mud of resistivity ρ = ρb, which penetrates a formation with resistivity of rocks ρ = ρr. The primary field E is produced by the charge of a current electrode A placed on the cylinder axis. In this paper the forward problem for the field E is investigated for the electrode A at an arbitrary point off the axis of a borehole embedded in a transversely isotropic formation, with an anisotropy axis parallel to the borehole axis. The solution of forvard problem is used in algorithms and respective software for processing resistivity logs affected by electrode eccentricity and formation anisotropy. The changes caused to apparent resistivity by the two effects are estimated in percent for axial and lateral electrode dispositions. © 2016

The Middle Siberian volcanic plateau is characterized with respect to its paleoecological environments. In this area, volcanism commenced in the Severodvinian (Vishkilian) Age. The lower (tuffaceous) part of the plateau section (Lebedev deposits) was formed in the Vyatkian Age. Its middle (tufflava) part (Khungtukun deposits) is correlative with the Goudikeng Formation (interval of 65–111 m) in the Dalongkou type section of China and corresponds to the Quadrocladus pachyphyllus.. Echinolimnadia mattoxi Zone. The top of this sedimentary unit (111 m up from the base of the Goudikeng Formation) should be correlated with the base of the Otoceras Ecozone. The upper (lava) part of the plateau (Putorana deposits) corresponds to the interval of 111–210 m, belongs to the Elatocladus linearis.. Cornia vosini Ecozone, and is older than the Hindeodus parvus Zone, which is now considered as the basal unit of the Triassic marine sequences. The volcanic plateau section shows now evidence of any biotic crisis. © 2016, Pleiades Publishing, Ltd.

In this paper, we describe an algorithm for computing biorthogonal compactly supported dyadic wavelets related to the Walsh functions on the positive half-line ℝ+. It is noted that a similar technique can be applied in very general situations, e.g., in the case of Cantor and Vilenkin groups. Using the feedback-based approach, some numerical experiments comparing orthogonal and biorthogonal dyadic wavelets with the Haar, Daubechies, and biorthogonal 9/7 wavelets are prepared. © 2011 World Scientific Publishing Company.

Middle Siberian trappean volcanism is considered to have been one of the major causes of the fundamental biotic change at the Permian-Triassic boundary. Accumulation of tuffs dominated the initial stage of the volcanic plateau development (Exah time), while later (Khungturunian time), tuffs and lavas accumulated, and at the conclusive stage (Putoranian time) lavas prevailed. At the end of the eruptions the height of the plateau reached 1700 m. Over 200 species and 80 genera of plants, conchostracans, ostracodes, bivalves, fishes, gastropods are known from the Putoranian. This article contains the characterization of a Putoranian plateau biota for the interval between the conodont and ammonoid standards of the P-T boundary. © 2015, Pleiades Publishing, Ltd.

The formation of the Middle Siberian Traps has been considered one of the main causes for the change in the biota at the Permian-Triassic boundary. At the first stage of the formation of the volcanic plateau (Lebedevskian time), volcanism was dominated by tuffs; at the second stage (Khungtukunian time), by tuffs and lavas; and at the last stage (Putoranian time), by flood basalts. The paper presents a paleoecological characterization of the plateau at the middle (Khungtukunian) stage, immediately before the Permian-Triassic boundary (ammonoid standard). At the beginning of this stage the plateau reached an altitude of about 500 m above sea level, at the end of the stage it was higher than 800 m above sea level (Sadovnikov and Turlova, 2004). The Khungtukunian deposits have yielded more than 230 species, belonging to more than 70 genera of plants, conchostracans, ostracods, bivalves, and fishes. © 2015, Pleiades Publishing, Ltd.

One of the most complete sections of the Upper Devonian-Lower Carboniferous in the Nakhichevan Autonomous Region in Azerbaijan is described bed-by-bed. The section is located on the northeastern slope of Geran-Kalasi Mountain. The section features a continuous succession of marine beds and abundant fossils, including foraminiferans, bryozoans, tabulates, rugoses, brachiopods, ostracodes, crinoids, conodonts, and algae. A few ammonoids found in the section have not yet been identified. In the process of composing the 1:25000 scale geological map, a complex brachiopod zone is for the first time accepted as a major stratigraphic unit (indicating the stratotype and an assemblage of zonal brachiopod species). © 2011 Pleiades Publishing, Ltd.
