Solar PV and BIPV system: Barrier, challenges and policy recommendation in India

India receives sun's energy over 300 days a year most of the time. About 5000 trillion kWh per year sun's energy is incident over India's land area. Theoretically, a small fraction of total incident solar energy can meet the entire country's power requirements. There are many government schemes to promote solar power generation. The government of India initiated solar PV/BIPV policies to encourage industries and individuals to use solar energy powered systems for electricity generations. This article provides an overview of the solar energy status and application of BIPV system in India. It includes an assessment of the region's solar energy potential and solar PV/BIPV installed capacity. This paper gives a brief description barriers and challenges facing solar BIPV development in India. This study also provides the solar PV/BIPV policies and recommendations with reference to the Indian context

Moment Closures for Fusion Optimization

Turbulent heat loss in a fusion reactor limits its ability to confine heat and produce fusion energy. Exploring tokamak parameters to find configurations that minimize turbulent trans- port will help us optimize fusion reactors. However, exploring efficiently and accurately is a challenge. Gyrokinetic models can accurately calculate turbulence but are too expensive to explore a broad parameter space with. Gyrofluid models are cheap, but they rely on moment closures that break down in the presence of turbulence. In order to develop a fast and accurate model to explore with, we will need robust closures that correctly capture nonlinear kinetic effects. As a starting point, we have developed such a closure for a simplified nonlinear gyrokinetic system, DNA (Hatch et al.), which models ITG turbulence in an unsheared slab. Numer- ical tests in the DNA simulation show that out new Dynami Multi-Mode (DMM) closure out performs standard closures and extrapolates to different parameter regimes.Physic

Hepatocellular Carcinoma With Hepatic Vein and Inferior Vena Cava Invasion

Hepatocellular carcinoma (HCC) invades intrahepatic vessels causing tumor thrombosis. Infrequently, there is involvement of the hepatic vein (HV) and inferior vena cava (IVC). In this review, we summarize the epidemiology, classification, clinical features, and management of HCC with HV and IVC invasion. While the involvement of HV and IVC usually portends an overall poor survival, selected patients may be candidates for aggressive treatment and thus improving outcomes

LIQUID BIOPSY: THERANOSTICS AND PERSONALIZED ONCOLOGY

Cancer is linked with mutated genes, and the study of tumor-associated genetic alterations is gradually used for diagnostic and treatment purposes. The solid tumors are now obtained from biopsy and/or surgical or biopsy specimens. Tumor cells release circulating free DNA into the blood, but the majority of circulating DNA are often not of cancerous origin, and the detection of cancer-associated alleles in the blood has long been unbearable to achieve. Modern science has overwhelmed these restrictions, making it possible to identify both genetic and epigenetic aberrations. A liquid biopsy (LB) or blood sample can provide the genetic landscape of all cancerous lesions (primary and metastases) as well as offering the opportunity to systematically track genomic evolution. This communication will explore how LB is associated with personalized oncology to predict response to treatments and the development of acquired resistance

Altered high density lipoprotein (HDL), triglyceride (TG) and anthropometric measurements in normal, overweight and obese under graduate medical students

Background:Obesity has reached epidemic proportions inIndia, affecting 5% of the country’s population. Urbanization and modernization has been associated with obesity in population of younger generation. The aim of the study was to find out variation in metabolic indicators (HDL, TG and anthropometric measurements) of normal overweight and obese undergraduate medical students.Methods:Total of 194 students took part in this study. Their height, weight and waist circumference were measured by standard methods. Their serum was estimated for HDL, TG and, fasting sugar on fully automatic Vitros 250 dry chemistry analyser from Orthoclinical diagnostics from Johnson & Johnson USA.Results:Over all females students were more overweight (Females 16% and Males 8%) and obese (F 18%, M 9%) as compared to males. Blood pressure, weight, waist circumference, HDL, and TG levels were more in overweight and obese group as compared to normal group.Conclusion:The results of the current study have shown an increasing trend of obesity and derangement of metabolic indicators among under graduate medical students

A Study on Consumer Buying Behaviour of Insecticide in Prayagraj Uttar Pradesh

Insecticides are the substances which are used to kill insects. They have the potential to alter ecosystem components majorly and are toxic to animals as well as humans. Some insecticides become concentrated as they spread in the food chain. Insecticides are insecticides that are formulated to kill, harm, repel or mitigate one or more species of insect. Insecticides work in different ways. Some insecticides disrupt the nervous system, whereas others may damage their exoskeletons, repel them or control them by some other means. They can also be packaged in forms including sprays, dusts, gels, and baits. It has been revealed during the study that there is availability factor which are affecting buying behaviour of TAKAF by different categories of respondents are availability at wholesaler shop (29.16%), availability at retailer shop (58.33%) and availability on online platform (12.50%) respectively. It has been revealed during the study that there is quality factor which are affecting buying behaviour of TAKAF by different categories of respondents are preventive (33,33%), curative (37.50%) and Safe to applicator (29.16%) respectively. It has been found during the study that the major constraint in marketing of  TAKAF was the high cost of transportation with 30 respondents response ranked I, followed by shortage of trading ranked II, followed by Price fluctuation with 18 respondents response ranked III, followed by High cost storage with 16 respondents response ranked IV, followed by  High prices with 15 respondent response ranked V, followed by storage with 14 respondents response ranked VI and lastly delayed sales with 6 respondent response ranked VII

Hydrodynamic effective field theory and the analyticity of hydrostatic correlators

We study one-loop corrections to retarded and symmetric hydrostatic correlation functions within the Schwinger-Keldysh effective field theory framework for relativistic hydrodynamics, focusing on charge diffusion. We first consider the simplified setup with only diffusive charge density fluctuations, and then augment it with momentum fluctuations in a model where the sound modes can be ignored. We show that the loop corrections, which generically induce non-analyticities and long-range effects at finite frequency, non-trivially preserve analyticity of retarded correlation functions in spatial momentum due to the KMS constraint, as a manifestation of thermal screening. For the purposes of this analysis, we develop an interacting field theory for diffusive hydrodynamics, seen as a limit of relativistic hydrodynamics in the absence of temperature and longitudinal velocity fluctuations.Comment: 24+1 pages. v2: References added, typos fixed, matches version published in JHE
