The search is mainly carried out on the basis of a theoretical model of the generation of electromagnetic emissions during the earthquake preparation period and earthquake prediction methodology. It is shown that this parameter is capable of describing the fault formative process in the focal area. Besides, VLF/LF electromagnetic radiation frequency analysis gives the possibility simultaneously to determine all necessary three characteristic parameters (magnitude, epicenter, time of occurring) for incoming earthquake prediction with great precision.展开更多

Not surprisingly, the problem of earthquake prediction has occupied scientists’ minds for more than two thousand years.

An integrated approach is used to identify anomalies and make predictions, including satellite remote sensing techniques and data from ground-based instruments. Terabytes of information are currently processed every day with many different multi-parametric prediction systems applied thereto. Alerts are issued if anomalies are confirmed by a few different systems. It has been found that geophysical patterns of earthquake preparation and stress accumulation are similar for all key seismic regions. The same earthquake prediction methodologies and systems have been successfully applied in global practice since 2013, with the technology successfully used to retrospectively test against more than 700 strong and major earthquakes since 1970. In other words, the earthquake prediction problem has largely been solved. Throughout 2017-2021, results were presented to more than 160 professors from 63 countries.展开更多

In laboratory experiments, the level of activity of hydrolytic enzymes in insects and the level of activity of these enzymes inhibitors in the leaves of three potato varieties differing in their resistance to the Colorado potato beetle have been determined. The results show that the insects-representatives of different samples have different food activity in relation to different potato varieties. High mortality rates were revealed at feeding with leaves of potato of the Bashkir variety characterized by a high level of hydrolases inhibitors and relatively rapid development of necrotic reactions after the appearance of eggs laying on the leaves. We suppose that the neerogenetic barrier appearing in the form of necrosis is the major cause of the fetal mortality of insects. The level of the content of inhibitors inactivating larvae digestive enzymes affects the survival of insects at postembryonic stages. The speed of the necrosis emergence, the level of activity of digestive enzymes inhibitors in potato can be considered as criteria for the selection of breeding material for resistance to the Colorado potato beetle.展开更多

Research into the character of the mode of action of these substances on various living systems is necessary to elucidate the possible unfavorable biological consequences and improve measures on their ecological safety. In this work, the effect of acridone-N-acetic acid on mushroom mycelial growth was tested and the culture of basidiomycete Lentinula edocles （shiitake） has been used. The influence of acridone additive upon the fungal mycelium growth on liquid （submerged） and agar media was examined within the wide concentration range of acridone carboxy-derivative. The results obtained testify to the relative ecological safety of these substances for mushroom organism, and to the mycelial growth promoting capability of acridone-N-acetic acid at favorable concentrations, both under the solid-phase and liquid-phase culture conditions. In fact, the very first step toward the investigation into the systems ＂macromycete-acridone series compound＂ has been made.展开更多

Coleman contributed to this study largely, although Bourdieu introduced the concept of a theoretical understanding of capital varieties. He was interested in the convergence of social, cultural, and economic capital. The authors propose to focus on the cultural capital of both the qualitative characteristics of the state of society. The problem is that in the presence of cultural capital as a funded system of values in the form of works of art and science, society degrades morally. Any cultural capital based on traditional religious values. This does not mean the broadcasting of religious themes in works of art, although it excludes, but rather a philosophical position of artists and researchers, through which the public receives the interpretation of events, their assessment of a certain value-regulatory system of coordinates. This element is the spiritual capital of the company and is a fundamental element of cultural capital. Qualitative state of society, its morality depends on the amount of spiritual capital, which he occupies in the field of cultural capital. A striking example of how the degradation and spiritual revival of capital in society can serve as the processes that took place during the last century.展开更多

It has formed stress in organisms, to eliminate the stress, there starts over various biochemical and physiological mechanisms for protection. Therefore, a large variety of plants to examine ways of increasing the resistance against stress factors have a scientific and practical importance. Thus, the primary processes of photosynthesis, based on the results of the study and its corresponding morphophysiological higher photochemical activity, has been found in a range of genotypes. Their leaves and plants assimilate the biological productivity of the intensity of the symptoms associated with the use of photosynthetic learned of the opportunity to create a new perspective varieties. This allows the research to prove the expansion of the electronic delivery of high-yielding genotypes and phosphorised chloroplast high speed, as well as the pH of thylacoid membranes are characterized by a great price, also photosynthetic electron transport, CO<sub>2</sub> assimilation and it was approved to be the link between productivity.展开更多

Industrial pollution and old mining methods are one of the sources of harmful agents in the environment. It is important to study and monitor environmental pollution in dynamics. During several years we have been researching heavy metals distribution in soils in the South East part of Georgia. “RMG Gold and Copper” mine in Kazreti is one of the biggest enterprises in Georgia. As a result of open-cast mining aerosols containing heavy metals are ejected which causes harmful effects of the environment. Within this research 21 villages in Bolnisi and Dmanisi municipalities were investigated;analysis of agricultural soils showed that the concentration of cadmium in the vicinity of the enterprise was significantly increased and exceeded maximum allowed concentrations. Through the wind, cadmium-containing dust spreads out to the 22展开更多

We think that the obstacle for creating of effective anti-cancer drugs could be existing idea that the basis of cancer is caused by the damage of the genetic apparatus of the cell. In this paper, we present the pathogenesis of cancer which is based on the formation of the special sustainable pathophysiological state of the organism what we call the state of “cancer reparative trap”. The essence of this pathophysiological state of the organism is in the reparative orientation of the immune system of cancer patients, when constant tissue repair is accompanied by systemic suppression of the anti-tumor immunity. Specifically, during the long-term exposure to carcinogens (exogenous and/or endogenous), the continuous tissue damage occurs which induces permanent stimulation of cell proliferation (imbalanced Th1 < Th2 lymphocytes, M1 < M2 macrophages, inflammation, angiogenesis, etc.) in order to repair the tissues damaged. At the same time, tissue repair is necessarily accompanied by the suppression of anti-tumor immunity (increase in T-regulatory cells, imbalanced Th1 Th2 lymphocytes, M1 < M2 macrophages et al.), which creates the necessary conditions for the survival of the malignantly transformed cells, formed by the action of carcinogens. The determining role of the imbalance in the autonomous nervous system (simpathetic/hypersympathetic dominance) in the development, maintenance and generalization of the cancer process has been shown. The explanation of a number of phenomena has been presented: the cell resistance to chemotherapy, and the phenomenon of cancer cell dormancy. The promising approaches for the cancer management in clinical practice have been proposed.展开更多

文摘Objective:To examine the frequency of C825T G protein β3 subunit gene polymorphism and its association with obesity of ethnic Kyrgyz.Methods:The study enrolled 210 people,89 patients(35 females,54 males)with obesity(BMI≥30 kg/m2)and 121 practically healthy patients(38 females,83 males)with normal body weight and no signs of type 2 diabetes(group of control),who were not observed before by a cardiologist.The blood pressure,anthropometry,glucose and lipid profile were examined among all subjects.Genomic DNA was extracted from peripheral blood cells.G proteinβ3 subunit C825T polymorphism was determined by polymerase chain reaction(PCR).Results:TT and CT genotypes carriers were grouped together in one group because the TT genotype was rare.CT+TT genotype frequency in the group with obesity made 0.72 and was significantly higher than that in the control group-0.52(χ2-8.44;P=0.004;odds ratio-2.55;95%CI 1.31-4.23).The statistical analysis revealed that hypertension(45%vs.31.3%,P=0.049)and obesity(51.2%vs.30%,P<0.01)occurred significantly more often in CT+TT genotype carriers than in the CC homozygotes.The results of the multivariate logistic regression analysis showed that the presence of 825T allele(exp β-2.89;95%CI 1.25-6.7;P=0.013),along with the occasional consumption of vegetables(exp β-3.47;95%CI 1.52-7.94;P=0.003)was the significant risk factor for obesity,regardless of gender,age and level of physical activity.In the construction of the similar regression model for hypertension,the statistically significant role of 825T allele was lost after adjustment for obesity as an independent variable.Conclusion:G protein β3 subunit gene C825T allele in the Kyrgyz ethnic group has an association with obesity.
文摘The results of research on the adsorption characteristics of materials based on fibrous carbon (CNF) are considered in this paper. It is shown that changing the conditions and procedure of CNF modifying namely specific adsorption surface, volume of the pore space, and parameters of the pore structure it became possible ultimately to vary in a wide range the adsorption characteristics of obtained materials.
