Wind energy conversion systems are now occupying important space in the research of renewable energy sources. There is a need for further research on Wind Generators and Power Integration Topologies. In this work we are using Permanent Magnet Synchronous Generator (PMSG) for wind power generation and the behavior of PMSG when subjected to different wind speeds is being studied in MATLAB. This also provides a comparison of different power converter topologies used in Wind Energy Conversion System (WECS).

ROS occur continuously in all the cells as a part of normal cellular function and are a potential double -edged sword in diseases prevention and promotion. When ROS present in high enough concentration, can damage cellular proteins, lipids and nucleic acids that may promote various diseases. Advances in research have shown that low to moderate concentrations of ROS play crucial roles in normal physiological processes, such as through redox regulation of protein phosphorylation, ion channels and transcription factors etc. and are also required for biosynthetic processes, including thyroid...

Peach is the leading temperate fruit crop after apple and pear. In Punjab, peach fruits are harvested in May when temperature and relative humidity is high. The fruit is highly perishable in nature and cannot be stored for longer time at ambient temperature. Proper storage extends the period of availability of peach fruits by reducing the rate of respiration and minimizing transpiration losses during period between harvest and consumption. Therefore a systematic study needs to be carried out to access the effect of pre-harvest sprays on quality of peach. Peach is a perishable fruit and...

The present study suggests that as the oxidative stress increases with the duration & with number of smoking and there is a progression in atherosclerosis. The levels of malondialdehyde, total cholesterol, triglyceride, LDL-cholesterol and VLDL- cholesterol are significantly higher in healthy smokers, IHD with smoking and IHD without smoking in comparison to normal healthy control whereas the levels of superoxide dismutase antioxidant enzyme and HDL- cholesterol were significantly lowered in the patients of healthy smokers, IHD with smoking and IHD without smoking. The levels of MDA...

Importance of sustaining the environment and the urgency of the situation cannot be disregarded in today's era of environmental concerns and global warming. Most of the companies are becoming conscious of impact of their operations on environmental and are making policies to demonstrate the company's commitment towards mitigation of its direct and indirect environmental impacts. Many actions include planning their facilities in an environment-friendly manner leaving a minimal footprint on the neighboring environment, minimizing the destruction of natural areas, habitats, bio- diversity and...
