TL;DR: In this article, the authors have focused on the role of the autonomic nervous system in the regulation of HRV and different variables affecting HRV, and provided a piece of all-inclusive information about heart rate variability.
Abstract: Background The heart is the central organ of the circulatory system which maintains the flow of blood along with the transport of nutrients to different cells and tissues. A well-functioning cardiac state is a complicated mode of changeability. A healthy heart is not only about oscillation as the rhythmometer is not the same in every circumstance. Heart rate shows variations so that it can be regulated according to psychophysiological conditions to maintain the effect of the internal-external stimulus. Objective The main objective of this review is to provide a piece of all-inclusive information about heart rate variability (HRV) and different variables affecting HRV. The direct interconnection among factors and so that HRV can be used in clinical practices. Methods This review article contains a detailed survey of literature about HRV available in different online sources such as; Google Scholar, Science Direct, PubMed, and Web of Science, etc. In this review, the authors have focused on the role of the autonomic nervous system in the regulation of HRV and the role of various factors affecting HRV. Results The variation in the time between two heartbeats is termed as HRV. It is one of the indicators of many pathological conditions related to cardiovascular health. It provided reliable information about the interaction of the sympathetic and parasympathetic nervous systems. The analysis of the variation of heart rate is a well-known non-invasive technique to identify the functioning of the autonomic nervous system. The autonomic nervous system (ANS) depends on the sympathetic and parasympathetic nervous system for transferring information. The cardio-accelerating center, lungs, and non-striated muscles are innervated by cardiac sympathetic nerves. This division of ANS latches upon the heart accordingly via the cervicothoracic ganglion and vagus nerve. It is found that cardiac normal variability depends upon this stimulation towards the sinoatrial node (pacemaker) which can be evaluated by analyzing the HRV. In human- based studies, it has been found that low level of HRV is one of the main causes of death rate among adults. Hence, HRV helps in identifying the risk of cardiac diseases and the state of ANS. Conclusion The heart plays a vital role in the human body and the well-functioning of the cardiac system is the need for a healthy life. The heart contains its nervous system termed as neurocardio system in which ANS plays a key role in which the sympathetic and parasympathetic system interplay to regulate HRV. High HRV is associated with healthy condition while low HRV is associated with pathological conditions. The HRV is influenced by various variables such as; pathological, physiological, psychological, environmental factors, lifestyle factors, and genetic factors, etc.

TL;DR: It is clear from present study that the alpha accompanied cold ternary fission reactions of 257Fm having minimum driving potential, maximum fission yield and small fission half lives for 48Ca +-205Pt + 4He is recognized as most probable alpha ternARY fission fragments of 257fm due to the presence of doubly magic nucleus 48Ca.
Abstract: The probable α-accompanied cold ternary fission fragments of 257Fm are studied using six types of nuclear proximity potentials. We have studied the driving potential, probability, relative yield and half-lives of possible alpha ternary fission fragments. It is clear from present study that the alpha accompanied cold ternary fission reactions of 257Fm having minimum driving potential, maximum fission yield and small fission half lives for 48Ca + 205Pt + 4He. Hence this combination is recognized as most probable alpha ternary fission fragments of 257Fm due to the presence of doubly magic nucleus 48Ca. This study finds important in the experiments on alpha ternary fission of 257Fm.

TL;DR: The results suggests that the hydroalcoholic extract of leaves of A. indica possess significant potential as hepatoprotective agent.
Abstract: Oral administration of hydroalcoholic extract of A. indica (250 and 500 mg/kg) effectively inhibited CCl4 and paracetamol induced changes in the serum marker enzymes, cholesterol, serum protein and albumin in a dose-dependent manner as compared to the normal and the standard drug silymarin-treated groups. Hepatic steatosis, fatty infiltration, hydropic degeneration and necrosis observed in CCl4 and paracetamol-treated groups were completely absent in histology of the liver sections of the animals treated with the extracts. The results suggests that the hydroalcoholic extract of leaves of A. indica possess significant potential as hepatoprotective agent.

21 Apr 2017TL;DR: This review focus on the standards of inverter for grid connected PV system, several inverter topologies for connecting PV panels to the three phase or single phase grid with their advantages and limitations.
Abstract: The demand of renewable resources has been increasing rapidly due to the environmental concerns and need of energy. Solar photovoltaic energy is currently one of the most popular and renewable energy resource on the earth. Inverter is essential component in grid connected PV systems. This review focus on the standards of inverter for grid connected PV system, several inverter topologies for connecting PV panels to the three phase or single phase grid with their advantages and limitations. In this paper different converter topologies used for inverter are carried out and comparison of various inverter topologies has discussed according to their efficiency, energy harvesting, cost, shading effect and reliability.
