This article presents the approximate analytical solutions to solve the nonlinear FornbergWhitham equation with fractional time derivative. By using initial values, the explicit solutions of the equations are solved by using a reliable algorithm like homotopy perturbation method. The fractional derivatives are taken in the Caputo sense. Numerical results show that the HPM is easy to implement and accurate when applied to time-fractional PDEs. © 2010 Elsevier Ltd. All rights reserved.

The Gujjar Rehabilitation Programme (Uttarakhand, India) is an integrated approach focusing on environmental conservation and providing better livelihood opportunities for pastoral Gujjar communities. The primary objective of this present study is to assess the response of rehabilitated Gujjar families to the resettlement Programme. Socio-economic assessments (e.g. livelihood status) of affected people at the two resettlement sites (Pathri and Gaindikhatta) were conducted. Resettled Gujjars reported enhancement of their livelihoods and many more children receiving schooling. Additionally, state government departments and several NGOs are making efforts to strengthen the prospects of Gujjar women through training and education programmes.

In the present study a methodology has been proposed to evaluate the performance of the V down perforated baffle roughened rectangular channel using hybrid FAHP-FOPSIS approach. The hybrid FAHP (fuzzy analytical hierarchy process) and FTOPSIS (fuzzy technique for order preference by similarity of an ideal solution) approach, taking into account PDAs (performance defining attributes), such as Nusselt number ratio, friction factor ratio, thermohydraulic performance parameter and effective efficiency, was used for the performance prediction of the V down perforated baffle roughened rectangular channel. The weight of different PDAs was evaluated by FAHP; Nurat (0.060, 0.093, 0.138), frat (0.045, 0.066, 0.105), ε (0.170, 0.244, 0.352) and ηeff (0.431, 0.597, 0.821), respectively. FTOPSIS was employed to determine the optimum ranking of the V down perforated baffle roughened rectangular channel and the values obtained as;C6>C5>C8>C7>C9>C10>C2>C11>C12>C1>C3>C13>C14>C4>C15>C16. The test plate (alternative) with an open area ratio (β) of 24%, relative roughness pitch (P/e) of 2 and relative roughness height (e/H) of 0.4, exhibits the optimal formulation. © 2015 Elsevier Ltd.

The research work analyzed the impact of insertion of the V down perforated baffles in the performance of the channel flow. The test apparatus is created, and all experimentation completed in the test rig and the information gathered for Nusselt number and friction factor for distinctive arrangement of roughness parameters. The test results demonstrate the critical improvement in both the Nusselt number and friction factor of the roughened channel over the smooth conduit. The open area ratio has a significant effect on the performance parameters, and it was found that there is a significant decrement in the pressure drop with an increase in the open area ratio. Preference selection method implied on performance prediction of roughened channel with a distinctive arrangement of roughness parameters, configurations using different PDCs including Nusselt number ratio, friction factor ratio, thermo hydraulic performance factor, thermal efficiency, effective efficiency and exergetic efficiency, respectively. The results of PSI (Preference selection index) show that the optimal formulation among all the configurations is with an open area ratio (b): 12%, relative roughness pitch (P/e): 2 and relative roughness height (e/H): 0.4. © 2015 Elsevier Ltd.

Tuberculosis is one of most pervasive, respiratory transmitted diseases and has spread to every corner of the globe. According World Health Organization report, as much as one-third of the world's population is currently infected by tuberculosis. There has been considerable interest in the currently used antimycotubercular compounds to inhibit or prevent mycobacterium species. These mycobacterium species have developed resistant against currently used drugs and produced toxic effect on long duration of therapy. These agents have different structure and almost all compounds having heterocyclic ring having one and more than one heteroatoms. These observations have been guiding for the currently used and newly developed antitubercular agents that possess potent antimicrobial activity and their side effects, activity against multi drug resistance MDR, XDR mycobacterium, and also in patient co-infected with HIV/AIDS. © 2011 Institute of Oriental Medicine, Kyung Hee University.
