Atmospheric deposition of 7Be,210pb and 210po during typhoons and thunderstorm in Shanghai, China and global data synthesis

引用

Science China Earth Sciences 2020年第4期63卷 602-614页

作者： Juan DU Mark baskaran Jinzhou DU State Key Laboratory of Estuarine and Coastal Research East China Normal UniversityShanghai 200241China Department of Geology Wayne State UniversityDetroit 48202USA

Atmospherically-delivered ~7Be,^(210)po and ^(210)pb in bulk precipitation and air samples collected around the globe have provided valuable quantification on the rates of removal, as well as proportional mixing of attendant air masses;however, such studies during thunderstorm and typhoon events are limited. We report the first continuous time-series rainwater sampling and analysis of ~7Be,^(210)pb and ^(210)po from two typhoons and one thunderstorm during 2015 summer in Shanghai. The depositional fluxes within individual rain events of typhoons and thunderstorms varied by a factor of 10 for ~7Be, 5.7 for ^(210)pb, 7.4 for ^(210)po,and 7.0 for ~7Be/^(210)pb activity ratios(AR). Such large observed variations in the depositional fluxes of ~7Be,^(210)pb,^(210)po and ~7Be/^(210)pb activity ratios were attributed to air masses injected from surrounding high pressure system adjoining the typhoon to low pressure system within the typhoon. Based on ~7Be/^(210)pb activity ratios, we estimated the variations in the fraction of maritime and continental air masses into the typhoon. Observed constancy in the ^(210)po/^(210)pb AR indicates that the residence times of air masses contributing to the typhoon during heavy rain are similar. From a synthesis of global fallout of ~7Be and ^(210)pb during pulse events(precipitation≥50 mm from single rainout event), we quantify the importance of pulse events in the atmospheric fallout of these radionuclides.

A review on front end conversion in ocean wave energy converters

引用

Frontiers in Energy 2015年第3期9卷 297-310页

作者： Nagulan SANTHOSH Venkatesan baskaran Arunachalam AMARKARTHIK Department of Mechanical Engineering Bannari Amman Institute of Technology Sathyamangalam 638401 India

Harvesting the energy from ocean waves is one of the greatest attractions for energy engineers and scientists. Till date, plenty of methods have been adopted to harvest the energy from the ocean waves. However, due to technological and economical complexity, it is intricate to involve the majority of these energy harvesters in the real ocean environment. Effective utilization and sustain- ability of any wave energy harvester depend upon its adaptability in the irregular seasonal waves, situation capability in maximum energy extraction and finally fulfilling the economic barriers. In this paper, the front end energy conversions are reviewed in detail which is positioned in the first stage of the wave energy converter among other stages such as power take off （pTO） and electrical energy conversion. If the recent development of these front end energy conversion is well known then developing wave energy converter with economic and commercial viability is possible. The aim of this review is to provide information on front end energy conversion of a point absorber and emphasize the strategies and calamity to be considered in designing such kinds of devices to improve the energy harvesting competence. This will be useful to the engineers for speeding up the development of a matured point absorbing type wave energy converter.

Clinical and experimental research in antituberculosis drug-induced hepatotoxicity:a review

引用

Journal of Integrative Medicine 2017年第1期15卷 27-36页

作者： Udhaya Lavinya baskaran Evan prince Sabina School of Biosciences and Technology VIT University Vellore-632014 Tamilnadu India

Drug-induced liver injury is the common adverse effect seen in patients receiving antituberculosis drugs （ATDs）. There are several risk factors associated with the development of hepatotoxicity in such patients. Though there have been appreciable efforts taken by carrying out studies investigating the efficacy of several natural and synthetic compounds in minimising this effect, the only choice available for clinicians is withdrawal of drugs. This review would give a precise idea of ATD-induced hepatotoxicity its underlying mechanisms and alternative therapies for the same.

Analytic Study of Magnetohydrodynamic Flow and Boundary Layer Control Over a Wedge

引用

Acta Mathematicae Applicatae Sinica 2008年第4期24卷 541-552页

作者： M.Chandrasekar S.baskaran Department of Mathematics Anna UniversityChennai-600 025India Department of Mathematics S.S.N.College of EngineeringKalavakkamChennai-603 110India

A genuine variational principle developed by Gyarmati, in the field of thermodynamics of irreversible processes unifying the theoretical requirements of technical, environmental and biological sciences is employed to study the effects of uniform suction and injection on MHD flow adjacent to an isothermal wedge with pressure gradient in the presence of a transverse magnetic field. The velocity distribution inside the boundary layer has been considered as a simple polynomial function and the variational principle is formulated. The Euler-Lagrange equation is reduced to a simple polynomial equation in terms of momentum boundary layer thickness. The velocity profiles, displacement thickness and the coefficient of skin friction are calculated for various values of wedge angle parameter m, magnetic parameter ξ and suction/injection parameter H. The present results are compared with known available results and the comparison is found to be satisfactory. The present study establishes high accuracy of results obtained by this variational technique.
