Using observations and long term simulations of an ocean-biogeochemical coupled model, we investigate the biological response in the southern subtropical Indian Ocean (SIO) associated with Ningaloo Niño and Niña events. Ningaloo events have large impact on sea surface temperature (SST) with positive SST anomalies (SSTA) seen off the west coast of Australia(More)
The energy demand is growing rapidly and thus the need for a renewable source that will not pollute the environment is of prime importance. Some projections state that by 2050 the energy demand will be around 13 terawatts (TW). Yet majority of the energy requirements are satisfied by fossil fuels where as the use of renewable energy resources could help in(More)
In this paper, the characteristics of organic bulk heterojunction solar cells have been designed and modeled using MATLAB R2010a version. Here, organic solar cell is considered as a diode and an equivalent circuit is developed with series and shunt resistances to obtain the I-V characteristics of the model. Non-linear equations are obtained in by solving(More)
The antiulcer activity of ethanolic extract of Calotropis gigantea R.Br leaves (EECG) was investigated in pylorus ligation and ethanol induced ulcer models in experimental rats. In both models the common parameter determined was ulcer index. Ethanolic extract of Calotropis gigantea at a dose of 150 and 300mg/kg produced significant inhibition of the gastric(More)
