The transportation industry is transitioning from conventional Internal Combustion Engine Vehicles (ICVs) to Electric Vehicles (EVs) due to the depletion of fossil fuels and the rise in non-traditional energy sources. EVs are emerging as the new leaders in the industry. Some essential requirements necessary for the widespread adoption of EVs include sufficient charging stations with numerous chargers, less to no wait time before charging, quick charging, and better range. To enable a quicker transition from ICVs to EVs, commercial organizations and governments would have to put in a mammoth effort, given the low number of installed chargers in developing nations such as India. One solution to lower the waiting time is to have multiple vehicles charging simultaneously, which might involve charging two- and four-wheelers simultaneously, even though their battery voltage ratings differ. This paper begins by providing the details of the power sources for EV charging, the charging levels and connector types, along with the specifications of some of the commercial chargers. The necessity of AC-DC converters in EV charging systems is addressed along with the power quality concerns due to the increased penetration of EVs. Next, a review of the existing research and technology of isolated DC-DC converters for simultaneous charging of EV batteries is provided. Further, several potential isolated DC-DC converter topologies for simultaneous charging are described with their design and loss estimation. A summary of the existing products and projects with simultaneous charging features is provided. Finally, insight is given into the future of simultaneous charging.

The proposed research explores Multi-Walled Carbon Nanotube’s (MWCNT’s) effect on the mechanical buckling behavior of glass fiber-enhanced thermosetting composites using UTM and the load vs displacement curve is plotted. Using the inflection point method, the critical buckling load is obtained from the load vs displacement curve for beams with three different volume fractions of MWCNT. The nonlinear finite element method is used to numerically obtain the load vs deflection curve and the numerical results are compared with the experimental results, and a close match is found with the experimental results. It is observed that the nonlinearity associated with the structure can significantly reduce the critical buckling load. The critical buckling load is found to increase and reported a 27.4% increase in buckling load with 0.3 wt.% of MWCNT which could be accounted for the increase in flexural modulus of the material.

This inquisition is to abstraction the inert contents of fly bottom ash. Fly bottom ash is the biggest pollution in land. Fly bottom ash occupy more space and it causes land pollution. Utilization of fly bottom ash in different region. It is a material which capture and store atmospheric carbon di oxide. Fly ash is mostly used in construction works. Mixing of some minerals in fly ash like Calcium sulphate dihydrate and calcium hydrated and it will increase the ability of using fly bottom ash in construction works. The main reason for choosing the construction region is the maximum demand is on construction works now a days. Using calcium sulphate dehydrate and calcium hydrated for increasing the strength of bricks. Pollution made by a thermal industry are more and so using some technology to reduce it. Dr. V.

This paper describes the enhancement of thermal performance of heat pipe using SiO2 and TiO2 nano fliuds. The experimentation explains about the effects of heat pipe inclination and heat input on the thermal efficiency and thermal resistance. Heat pipe is an advance type of heat exchanger which transfers huge amount of heat due to the effect of capillary action and phase change heat transfer principle. Recent developments in the heat pipe with high thermal conductivity through nano fluids. This paper reviews, influence of various factors such as heat pipe tilt angle, charged amount of working fluid, nanoparticles type, size, mass volume fraction and its effect on the improvement of thermal efficiency, heat transfer capacity and reduction in thermal resistance. The nano fluid preparation and the analysis of its thermal characteristics also have been reviewed. Arunkumar. G | Dr. P. Navaneetha Krishnan | Dr. T.

Calocybe indica (Milky mushroom) is one of the easily available and culturable mushrooms at relatively low cost. It comprises economic source of protein enriched with antioxidants and immune enhancing factors required for human health. Medicinal property of C. indica is due to the presence of polysaccharides, proteins, aminoacids, terpenes, terpenoids and phenols. In this study, methanolic extract of C.indica was used for invitro antioxidant, Protein denaturation inhibition, Nitric oxide scavenging and Membrane stabilization assays. Total Antioxidant activity (TAA) and phenolic content of Laboratory grown C. indica by phosphomolybdenum method was equivalent to that of ascorbic acid. Antiinflammatory effect was estimated by protein denaturation inhibition assay exhibits inhibition of 66.80 % at 1000 µg/ml. C.indica also found to possess nitric oxide scavenging activity capable of 69.76 % inhibition at 1000 µg/ml. Membrane stabilization assay revealed that methanolic extract of C.indica provides 55.83 % membrane stabilization. Key words: C. indica, Antioxidant, Antiinflammatory, Nitric oxide, Membrane stabilization
