Or are women merely the lucky recipients of developmental patterns favored by selection to produce orgasm in males? A recent and widely publicized book by Elisabeth Lloyd (2005a) contends that there is insufficient evidence to validate any of the adaptive explanations yet proposed for female...

A study was conducted for six weeks period to evaluate the effect of meat byproduct Sinews on commercial broiler performance in a total of 270 unsexed Vencobb chicks. The experimental feeds were prepared by including sinews at zero per cent (controlT1), 2 per cent (T2) and 4 per cent (T3) level in the feed. Addition of two per cent inclusion of Sinews in broiler chicken diet did not showed sign...

BACKGROUND Biodiesel production using Pongamia pinnata (P. pinnata) seeds results in large amount of unused seed hull. These seed hulls serve as a potential source for cellulose fibres which can be exploited as reinforcement in composites. METHODS These seed hulls were processed using chlorination and alkaline extraction process in order to isolate cellulose fibres. Scanning electron microsco...

Introduction: Tiny spheroidal objects in the size range from 40-150 nm are common in sedimentary rocks, and have been interpreted as the fossilized remains of minute life forms [1,2,3]. Because etching and mineral precipitation can produce oval shaped artifacts in the size range of nannobacteria, there was always some scepticism in this regard. However, when similar looking objects were discove...
