In the framework of liberalized deregulated electricity market, dynamic competitive environment exists between wholesale and retail dealers for energy supplying and management. Smart Grids topology in form of energy management has forced power supplying agencies to become globally competitive. Demand Response (DR) Programs in context with smart energy network have influenced prosumers and consumers towards it. In this paper Fair Emergency Demand Response Program (FEDRP) is integrated for managing the loads intelligently by using the platform of Smart Grids for Residential Setup. The paper also provides detailed modelling and analysis of respective demands of residential consumers in relation with economic load model for FEDRP. Due to increased customer’s partaking in this program the load on the utility is reduced and managed intelligently during emergency hours by providing fair and attractive incentives to residential clients, thus shifting peak load to off peak hours. The numerical and graphical results are matched for intelligent load management scenario.

Drought is one of the most prevalent abiotic stresses that adversely affect rice productivity(Petrozza et al, 2014). Rice is very sensitive to drought stress and drought can cause 50% reduction in rice production globally(Yang et al, 2008). To meet the food needs for global population, 63% more agricultural production will be required by the year 2050 than.

A kinetic flux-vector splitting (KFVS) scheme is applied for solving a reduced six-equation two-phase flow model of Saurel et al. [1]. The model incorporates single velocity, two pressures and relaxation terms. An additional seventh equation, describing the total mixture energy, is added to the model to guarantee the correct treatment of shocks in the single phase limit. Some salient features of the model are that it is hyperbolic with only three wave propagation speeds and the volume fraction remains positive. The proposed numerical scheme is based on the direct splitting of macroscopic flux functions of the system of equations. The second order accuracy of the scheme is achieved by using MUSCL-type initial reconstruction and Runge-Kutta time stepping method. Moreover, a pressure relaxation procedure is used to fulfill the interface conditions. For validation, the results of suggested scheme are compared with those from the high resolution central upwind and HLLC schemes. The central upwind scheme is also applied for the first time to this model. The accuracy, efficiency and simplicity of the KFVS scheme demonstrate its potential for modeling two-phase flows.

The present study was aimed to assess the potential of infertility to induce the adverse effects with reference to testosterone, Triiodothyronine (T3), Thyroxine (T4), Alanine Aminotransferase (ALT), Aspartate Amino-transferase (AST), zinc, copper and iron. All the samples were divided into four groups according to age and disorder (Group 1, 10 infertile men of 25-40 years;Group 2, 10 fertile men of 25-40 years;Group 3, 10 infertile men of 41- 60 years and Group 4, 10 fertile men of 41-60 years). Semen and blood samples were analyzed by atomic absorption spectrophotometry to determine minerals while, Testosterone, T3 and T4 were determined by enzyme immunoassay kits. ALT and AST were determined using standard kit assay method. The levels of testosterone and T3 and AST in the fertile semen of 41-60 years age group were increased significantly (P ≤ 0.001) as compared to that of fertile semen of 25-40 years age group. While, the level of T4 in the fertile semen of 41-60 years age group was decreased significantly (P ≤ 0.001) as compared to that of fertile semen of 25-40 years age group. In case of fertile serum, only the level of testosterone was significantly decreased (P ≤ 0.05) in the 41-60 years age group as compared to 25-40 years age group. The levels of testosterone and Cu in the infertile serum of 41-60 years age group were decreased significantly (P ≤ 0.001). While, the levels of T3, T4, ALT and Fe in the infertile serum of 41-60 years age group were increased significantly (P ≤ 0.05) as compared to that of infertile serum of 25-40 years age group.
