(Perovskites Photovoltaic) PPV cells are the hottest topics in solar cells in the recent years, because of the remarkable structural and electronic properties and hence rapid progress in material science. The Challenge associated with high-mobility BaSnO3 films is to grow. It shows high carrier mobility and UV-visible transparency has been attracting more and more attention as a very promising component for the next generation opto-electronics. Here, we demonstrate a Structural and Electronics properties (Sp and Ep), To characterize this compound theoretical calculation have been performed by using first principal method and the results show BaSnO3 is conductor at 0eV i.e. room temperature and gaining energy make more conduction transferring more electrons from conduction to valence bands. BaSnO3 shows 5.78e.v maximum for the conduction. We have studied this compound in ideal cubic phase. At 0° Kelvin calculation are performed to get different properties. No experimental studies have been done on this compound. And it was difficult to accumulate its experimental data. WC-GGA is used for the study of structural properties of BaSnO3. This Correlation potential can also be used for the calculation of the various perovskite. Depending on the cubic (ABX3) composition, perovskites exhibit a wide range of structural and electronic properties, which are optimized for different applications.
The future of a nation lies in the hands of its children. Health of children should be the first priority of a nation. It is an indicator of social and economic development. Pakistan falls among high child mortality rate countries. The aim of this paper is to assess the socioeconomic determinants of child mortality in the Punjab. For this purpose, the study obtains data from Multiple Indicator Cluster Survey (2014), conducted by Punjab Bureau of statistics. The data were collected with the help of well-designed three questionnaires from 38,405 households of Punjab. The STATA is used to apply Logistic model to determine the factors affecting child mortality. The dependent variable is dichotomous in nature based on this question "Have you ever given birth to a boy or girl who was born alive but later died?" and response is either yes or no. According to the empirical results of the study, area of residence, source of drinking water, women ever attended school and their level of education, women media awareness, women smoking and wealth quintiles are important socioeconomic determinants of child mortality. But comparatively, wealth quintiles have greater influence on reducing child mortality. The study suggests some policies to improve the situation, e.g., allocation of more budget for health, initiative of health care programs for women and infant, particularly in rural areas of Punjab.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
