Unshackling the tribal women in Indian English Literature: dreams and visions
Authors: Sharma Dr. Shreeja , Tripathi Prof. Shubhra
Published: March 2019

The marginalised tribal women comprise the weakest section of the Indian society. It is a sad reality that their identity remains weak, unvoiced and largely unexplored. Invigorating them would enhance the collective national capability as it will carry  justice, equity and development to the most vulnerable segment of the nation, thereby reinforcing and the frailest of its stalk. The portrayal of tribal women in literature can go a long way in spreading awareness about the cause, not only on the national, but also on an international scale. Writing on these marginalised, poor, and socially excluded women can in the long run, change the perception of the society and bring to attention the neglected lot, integrating them rightfully with society. Prominent writers including Mahasweta Devi, Kamala Markandaya and Gita Mehta among others have made important contributions in this area. While the tribal narratives voice the concerns of the tribals, there still remains lot of room for exploring and  expressing the concerns of these women for a feminist rendition . This paper examines the potential of writings on the female tribal protagonist.

Authors:   Dubna State University, Ryabkova Svetlana Aleksandrovna
Published: March 2019

Despite the fact that elite groups are a top priority for modern Russian political science, the term ‘elite’, the relevant concepts, and their applicability remain the focus of political debates. The research discuss-es the pressing issues of using a variety of method-ological approaches. The first challenge concerns the semantic and substantive aspects of the catego-ry of elite and its proper scientific application. The second one relates to the analysis of the identifica-tion criteria for the political elite, the advantages and disadvantages of various quota-based options for entering the political elite, and the theoretical and methodological tools suitable for their justification. The third issue deals with the development of the objective metrics to assess the quality and efficiency of the political elite.
Chinese panda diplomacy and state image
Authors:   St. Petersburg State University, Duo Wu
Published: March 2019

Panda diplomacy has been a popular diplomatic technique since the foundation of the PRC. It is re-garded as a pivotal tool for the development of Chi-nese public diplomacy. Since the introduction of the reform and opening-up policy, this resource has undergone several changes, but it still attracts the attention of the world community. In the new era, Beijing continues to implement panda diplomacy as it promotes a peaceful state image and is a form of soft power. Despite the fact that this diplomatic lev-erage has considerably affected the creation of Chi-na’s positive image in the global arena, this tech-nique is overlooked. The study discusses the histor-ical backgrounds to panda diplomacy and focuses on its positive effects. In conclusion, it is proposed to use the giant panda culture to improve and up-date China’s national image in the future.
Relevant prevention problems of the involvement of minors in antisocial actions
Authors:   Kuban State University, Rasulova Zaira Osmanovna
Published: March 2019

The study discusses the involvement of minors in antisocial actions and presents the novel preventive measures in this regard. A crime prohibited by Arti-cle 151 of the Criminal Code of the Russian Federa-tion poses a high risk to society because it affects physical and emotional health of a child going through all stages of personal development and growing up. The involvement of adolescents in anti-social actions leads to the inevitable destruction of positive values, and failure to suppress such an of-fense results in further criminalization and, accord-ingly, increased crime rates. Measures taken by pub-lic authorities are to prevent this process by identify-ing and addressing the causes and conditions of crimes and by using a variety of comprehensive measures to protect minors from the impact of ille-gal factors.

Published: March 2019

Оbject.The article presents the results of studies of secondary mineral formation in the lower Cretaceous sediments of the Bolshekhetskaya depression, which contain highly promising oil and gas deposits, with established industrial performance at Pyakyakhinskoye, Khalmerpayutinskoye and South-Messoyakhskoye fields. The objects under consideration are located in the most submerged part of the Nadym-Taz syneclise in the zone, where the Taz and Urengoy facies regions meet.

Materials and methods.Main types of postsedimentary changes of reservoir rocks selected on the basis of study of core material Pokurskaya, Angelovskaya, Sortymskaya and Megionskaya fms. Petrography and Mineralogy of the rocks under consideration were studied on the basis of stage analysis using optical and electron microscopy, and X-ray diffraction study at the Center of core and reservoir fluids research of “LUKOIL-Engineering’s KogalymNIPIneft branch In Tyumen” (Kogalym). Determination of the mineral type of zeolite was performed by X-ray phase analysis at the Institute of Geology and Geochemistry UrO RAS (Ekaterinburg).

Resuts.It was found that for rocks Pokurskaya, Angelovskaya, Sortymskaya and Megionskaya fms characteristic a diverse range of secondary minerals and structures, evidence of the background stage catagenesis and the superimposed processes. The most important among them is the regeneration of quartz, the transformation of feldspar, violation of the crystal structure of biotite, the formation of various clay minerals, crystallization of zeolites and calcite.

Conclusions.Studies show that the upper part of the section of the lower Cretaceous deposits of Bolshekhetskaya depression corresponds to the area of the middle catagenesis (gradation MK2), the bottom – changed to the stage of deep catagenesis (gradation MK3). In this case, the epigenetic process proceeded unevenly, pulsation, due to changing tectonic conditions. Particular attention is paid to the origin of zeolites, which is still debatable. It is assumed that their formation is associated with the transformation of “camouflage pyroclastic” in particular, feldspar clastics.

We report a new computational technique, PathFinder, that uses retrosynthetic analysis followed by combinatorial synthesis to generate novel compounds in synthetically accessible chemical space. Coupling PathFinder with active learning and cloud-based free energy calculations allows for large-scale potency predictions of compounds on a timescale that impacts drug discovery. The process is further accelerated by using a combination of population-based statistics and active learning techniques. Using this approach, we rapidly optimized R-groups and core hops for inhibitors of cyclin-dependent kinase 2. We explored greater than 300 thousand ideas and identified 35 ligands with diverse commercially available R-groups and a predicted IC50 < 100 nM, and four unique cores with a predicted IC50 < 100 nM. The rapid turnaround time, and scale of chemical exploration, suggests that this is a useful approach to accelerate the discovery of novel chemical matter in drug discovery campaigns.

Published: March 2019

We introduce a new heterogeneous CPU+GPU-enhanced DFTB approach for the routine and efficient simulation of large chemical and biological systems. Compared to homogenous computing with conventional CPUs, heterogeneous computing approaches exhibit substantial performance with only a modest increase in power consumption, both of which are essential to upcoming exascale computing initiatives. We show that DFTB-based molecular dynamics is a natural candidate for heterogeneous computing since the computational bottleneck in these simulations is the diagonalization of the Hamiltonian matrix, which is performed several times during a single molecular dynamics trajectory. To thoroughly test and understand the performance of our heterogeneous CPU+GPU approach, we examine a variety of algorithmic implementations, benchmarks of different hardware configurations, and applications of this methodology on several large chemical and biological systems. Finally, to demonstrate the capability of our implementation, we conclude with a large-scale DFTB MD simulation of explicitly solvated HIV protease (3,974 atoms total) as a proof-of-concept example of an extremely large/complex system which, to the best of our knowledge, is the first time that an entire explicitly-solvated protein has been treated at a quantum-based MD level of detail.
Extracting Design Principles for Efficient Thermally Activated Delayed Fluorescence (TADF) from a Simple Four-State Model

Published: March 2019

We introduce a simple quantum-mechanical model for thermally activated delayed fluorescence (TADF). The Hamiltonian is represented in the basis of four spin-mixed diabatic states representing pure charge transfer (CT) and local excitations (LE). The model predicts that it is possible to realize lowest-lying adiabatic singlet (S1) and triplet (T1) states with a small singlet triplet gap, differing CT/LE contributions, and appreciable LE component in the S1 state. These characteristics can explain the coexistence of fast T1→S1 reverse intersystem crossing and S1→S0 radiative decay in some chromophores. Through the sampling of the parameter space and statistical analysis of the data, we show which parameter combinations contribute the most to the TADF efficiency. We also show that conformational fluctuations of a single model donor-acceptor system sample a significant region of the parameter space and can enhance the TADF rate by almost three orders of magnitude. This study provides new guidelines for optimization of TADF emitters by means of electronic structure and conformation engineering.
Photo-Sensitizing Thin-Film Ferroelectric Oxides Using Materials Databases and High-Throughput Calculations

Conventional solar cell efficiency is usually limited by the Shockley-Queisser limit. This is not the case, however, for ferroelectric materials, which present a spontaneous electric polarization that is responsible for their bulk photovoltaic effect. Even so, most ferroelectric oxides exhibit large band gaps, reducing the amount of solar energy that can be harvested. In this work, a high-throughput approach to tune the electronic properties of thin-film ferroelectric oxides is presented. Materials databases were systematically used to find substrates for the epitaxial growth of KNbO3 thin-films, using topological and stability filters. Interface models were built and their electronic and optical properties were predicted. Strain and substrate-thin-film band interaction effects were examined in detail, in order to understand the interaction between both materials. We found substrates that significantly reduce the KNbO3 band gap, maintain KNbO3 polarization, and potentially present the right band alignment, favoring the electron injection in the substrate/electrode. This methodology can be easily applied to other ferroelectric oxides, optimizing their band gaps and accelerating the development of new ferroelectric-based solar cells.

Introduction: chemical dependence on several narcotic or other psychoactive substances at the same time is called poly-drug addiction or complicated drug addiction, the terms "combined addiction" and "combined use" are also often used. It is believed that the simultaneous or alternating regular intake of various psychoactive substances has a more destructive effect on the body than depending on only one drug. In the narcological literature the various forms of combined use of alcohol and heroin were described. There are some data on the psychological characteristics of patients with such forms of addiction, the specifics of these patients in terms of personal readiness for rehabilitation. The aim of the study was to identify the features of interpersonal relations and individual-personal specificity in the field of such relations in patients with heroin-alcohol polydrug addiction. Materials and methods: the Study has been conducted on a sample of 25 patients aged 28 to 50 years using four psychodiagnostic techniques. Tests were used: "Individual typological questionnaire of L.N. Sobchik " (ITO), "Questionnaire of interpersonal relations of A. Rukavishnikov" (OMO), "Diagnosis of interpersonal relations of T. Leary" (DMO), "Diagnosis of interference in the establishment of emotional contacts of V. Boyko". Results: it has been found that heroin and alcohol addicts in the communicative sphere are aggressive, deceitful, tend to dominate, although they retain the need to be accepted by others. Discussion and Conclusions: the obtained data confirm the literature data about more aggressiveness of polynarcomania in the comparison with mononarcomania. The tendency to aggression in interpersonal relations can be attributed to destructive, pathological and socially dangerous features of heroin and alcohol poly-drug addiction. Drug addicts of the studied form are dangerous for others and create communication problems for people forced to communicate with them. A generalizing conclusion is made that heroin-alcohol poly-drug addiction is a source of social destructiveness, and patients with this type of chemical addiction are carriers of this destructiveness.
