Renewable Energy Resource (Biofuel) For Sustainable Future
Abstract: The equal distribution of resources should be for all, irrespective of rich or poor. There must be a balance between the need and consumption. The developed countries are utilizing more resources as compared to developing countries. This imbalance is responsible for rich becoming richer and poor becoming poorer. This is due to sharp increase in population in developing countries. To achieve a sustainable life style, there should be equal distribution …

Hematological and Biochemical Changes in the Freshwater Fish, Pseudetroplus Maculatus Exposed to Sublethal Concentrations of Chlorpyrifos
Abstract: Sublethal effects of chlorpyrifos on hematological and biochemical parameters were assessed in the freshwater fish, Pseudetroplus maculatus. Fish were exposed to chlorpyrifos at two sublethal concentrations, 0.661 µg/L (one-tenth of LC50—96 h) and 1.32 µg/L (one-fifth of LC50—96 h), for 15 and 30 days maintaining the control group. Blood collected from the control and treated groups were used for analyzing the hematological and biochemical parameters. Chlorpyrifos exposure significantly (P<.05) decreased …
