Stability of (Mg,Fe)SiO3 perovskite and the structure of the lowermost mantle

Thermodynamic analysis shows that (Mg,Fe)SiO3 perovskite is stable throughout the likely pressure, temperature and compositional regime of the Earth's mantle. The breakdown of perovskite to its constituent oxides appears unlikely, even under the extreme conditions of the core-mantle boundary. This reaction had been proposed to reconcile estimates of silicate melting with seismic observation and proposed geotherms

Compression of tetrahedrally bonded SiO2 liquid and silicate liquid‐crystal density inversion

We have investigated the response to pressure of liquid SiO2 by performing a quantitatively realistic Monte Carlo simulation. The model liquid was restricted to at most four‐fold Si‐O coordination by the effective imposition of an infinite potential barrier to a fifth bond. We thus obtained an unambiguous comparison of the compression mechanisms of solid and liquid tetrahedral networks. In spite of this restriction, the density of the simulated liquid exceeds that of the corresponding models of quartz, coesite and cristobalite at high pressure. The efficient compression of the liquid results from a continuous restructuring of the network that leaves the mean Si‐Si distance virtually unchanged and does not require an increase in the coordination number. The restructuring is effected by local breaking and reconnecting of bonds, a mechanism that is not available to a perfect crystal

A Socio-Cultural Perspective of Women Education and Empowerment in Rural Bangladesh

The main focus of this study was to examine the role of education in increasing the level of women's empowerment particularly in the decision-making process at the household level and to find out how the socio-cultural factors (for genderbased awareness and the use of Purdah-related norms) influence women's education as well as empowerment in rural Bangladesh. The study was conducted in one of the districts of Dinajpur in Bangladesh. Three villages namely, Mashimpur, Mohiskotha and Jugibari which are situated under the Union of Auliapur at Sadar thana (sub-district) were chosen as study areas. The respondents of the study consisted of 340 women from the selected areas. To gather qualitative information, 27 respondents were also involved in this study. In order to gather the depth information, both quantitative and qualitative methods were employed in this study. The first objective of the study was to examine the awareness of gender-based factors in rural women's education as well as their empowerment. The study showed that in Bangladesh, socio-cultural ideology generates gender-based inequalities in education. As a result of the patriarchal ideology, most respondents consider sons as 'assets'. On the other hand, daughters are treated as nonpermanent family members in their natal home since they will move into their husband's house after marriage. Due to such beliefs and practices, women received less attention in education and as a result lack empowerment. The second objective of the study was to identi@ the role of the practice of Purdah-related norms and its influence on rural women's education as well as their empowerment. The results indicated that in Bangladesh most respondents had a 'non-traditional' ideology or non-conservative ideology about the practice of Purdah. Correlation coefficient was also conducted to examine the relationship between respondent's Purdah ideology and the socio-economic variables and the results showed that among the socio-economic variables religious status, education, occupation, income, total number of children and son's education were positively correlated with Purdah awareness although the strength of the relationship was weak. The third objective of the study was to examine the role of education and how education might help in increasing women's decision-making power (empowerment) at the household level. The results showed that women with higher education level i.e. those with higher secondary education and graduates, had more decision-making power compared to illiterate, primary and secondary educated women. Similarly, it was found that the women who full-time employed had more decision-making power than housewives and self-employed women. The findings also showed that respondent's educational attainment (r 4.47; p<0.01), occupation (r = 0.61; p<0.01) and income (r = 0.60; p<0.01) were positively related to their decision-making power. The fourth objective of the study was to determine the factors (particularly the independent variables) that might affect women's decision-making power (empowerment) at the household level. A multiple linear regression analysis was carried out and the results revealed that education, occupation, income and genderbased awareness had a significant influence on women's decision-making power (the level of empowerment). The analysis of variance (ANOVA) showed the overall significant of the linear regression model with F-test (p<0.001) for considerable adjustment of the model with the regression coefficient (R square) of 5 1.6. Overall, the study suggests that improvement in women's access to education particularly the higher level of education opportunities would increase women's employment and income. This could expand their ability to make decisions in the family and would play a key role in the empowerment of rural women

Impact of Belt and Road Initiative on India-south Asia Regional Trade Integration

Belt and Road Initiative BRI is a standout amongst the latest and remarkable regional economic integration strategies of Chinese government This initiative incorporates South Asia which is a piece of Asian territory From past researches we came to know that regional trade intensity among south Asian nations is low The majority of the analysts finished up by computing the general list at beneath 0 5 Notwithstanding various multilateral and reciprocal Free Trade Agreements FTA exchange coordination did not increment attractively India has reciprocal FTAs with every south Asian nation Also this sub region is among the significant exchange accomplices of India There are double suppositions of India about Chinese BRI initiative In this research we found an answer of an inquiry that regardless of whether BRI has sway on trade coordination among India and south Asian nations We utilized a blended gravity model equation from Hayakawa et al 2015 and Weerehewa 2009 inquire about papers to assess the aftereffects of variable

Corporate Social Responsibility in Bangladesh: The Law and Practices

Commitment of the business corporations to the society is of critical importance. In this article, the current scenario of corporate social responsibility (CSR), an emerging issue in the developing countries, is critically analyzed in reference with the existing laws and regulations in Bangladesh. This paper also examines the current status of CSR in readymade garment industries, the most important and vulnerable industrial sector in Bangladesh. It concludes that the major Bangladeshi laws related to corporate regulation and responsibility do not possess necessary features to develop a socially responsible corporate culture in Bangladesh. However, initiatives, from the local government and international community, have been taken to improve the situation.

EEG based assessment of emotional wellbeing in smart environment

Abstract. Smart technologies are frequently united and automated in our everyday settings and commonplace task by linking computers and other devices. While there has been a necessity to build smart environments for an easy and comfortable life, research on measuring wellbeing in this environment becomes increasingly intensive. Emotion is one of the decisive aspects of wellbeing that encourages us to work effectively, manage, and cope with stress, and affect our physical health. This work evaluates the EEG signal to measure individuals the different emotional states in a smart space by creating a computer gaming scenario. EEG, a physiological signal which provides details on mental, physiological, and emotional states, EEG frequency bands are strongly correlated with positive and negative emotional responses. Since brain left frontal cortical area is responsible for positive emotion and the right frontal region associate, therefore, we choose two pairs of EEG electrodes F3-F4, and F7-F8 to assess the game player emotional states during the gaming situations. We measure the EEG frontal alpha asymmetry (FAA) by comparing variations in the alpha band power levels in the left and right frontal cortex, corresponding to positive and negative emotions. Our experiment outcome reveals considerable support with the emotional variance of the test participants. We note that multiple interruptions during the gaming situation create irritation to the test subjects. These findings also confirm that F3 and F4 EEG channels are the most sensitive to human emotional responses compared to F7 and F8 channels

GR-284 Automated Vulnerability Detection in Source Code Using Deep Neural Networks

One of the most important challenges in the field of a software code audit is the presence of vulnerabilities in software source code. Every year, more and more software flaws are found, either internally in proprietary code or revealed publicly. These flaws are highly likely exploited and lead to system compromise, data leakage, or denial of service. C and C++ open-source code are now available in order to create a large-scale, machine-learning system for function-level vulnerability identification. We assembled a sizable dataset of millions of open-source functions that point to potential exploits. We created an efficient and scalable vulnerability detection method based on deep neural network models that learn features extracted from the source codes. To remove the pointless components and shorten the dependency, the source code is first converted into a minimal intermediate representation. We keep the semantic and syntactic information using state-of-the-art word embedding algorithms. The embedded vectors are subsequently fed into convolutional neural networks to classify the possible vulnerabilities. Furthermore, we proposed a new neural network model which seems to overcome issues associated with traditional neural networks. To measure the performance, we used evaluation metrics such as f1 score, precision, recall, accuracy, and total execution time
