Aid dispensed to the Peace Corps for humanitarian purposes was the major focus of the investigation. The research proposed that such aid should continue under the President Barack Obama administration. Approach: The approach taken used … …Journal of Social Sciences, Vol. 5, Issue 2 · 30 Jun 2009 · 8,053 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntrinsically Unstructured Proteins: Potential Targets for Drug DiscoveryPathan Salma, Chintan Chhatbar, Sriram SeshadriProblem statement: The function of a protein is dependent on its three-dimensional structure. However, numerous proteins lacking intrinsic globular 3D structure under physiological conditions had been recognized. These proteins are frequently involved in some of the most critical cellular control mechanisms and it appears that their rapid turnover, aided by their unstructured nature in the unbound state, provides a level … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 7,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtective Effect of Enicostemma littorale Blume on Rat Model of Diabetic NeuropathyNiraj Mukundray Bhatt, Suparna Barua, Sarita GuptaProblem statement: Poor glycemic control and oxidative stress is implicated as a common pathway in the development of diabetic neuropathy. Approach: In the present study, we investigated the protective effects of Enicostemma littorale Blume (EL) (2.5 g kg-1), a hypoglycemic and antioxidant herbal medicine in alloxan-induced diabetic neuropathy in male Charles foster rats. Results: Tail flick latency in hot immersion … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 7,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputable General Equilibrium Techniques for Carbon Tax ModelingAl-Amin, Chamhuri Siwar, Abdul HamidProblem statement: Lacking of proper environmental models environmental pollution is now a solemn problem in many developing countries particularly in Malaysia. Some empirical studies of worldwide reveal that imposition of a carbon tax significantly decreases carbon emissions and does not dramatically reduce economic growth. To our knowledge there has not been any research done to simulate the economic impact of … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractBackscattered Acoustic Energy by Monobubbles Experimental Approach and Statistical Study of the AttenuationAli Khelil, Claude ManteProblem statement: As the number of air bubbles in the sea is very high, they are so many acoustic diffusers who make illegible the recordings the purpose of which is to quantify the alive bodies. The signals backscattered by air bubbles constitute a parasite in offshore recordings and must be eliminated. It is planned to finalize techniques allowing the localization … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,579 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Flutter Derivatives of Bridge Decks in Wind Tunnel Test by Stochastic Subspace IdentificationT. Janesupasaeree, V. BoonyapinyoProblem statement: Flutter derivatives are the essential parameters in the estimations of the flutter critical wind velocity and the responses of long-span cable supported bridges. These derivatives can be experimentally estimated from wind tunnel test results. Generally, wind tunnel test methods can be divided into free decay test and buffeting test. Compared with the free decay method, the buffeting test … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,133 accessesView PDFCite
