The experimental treatments were laid down in a split plot design with three replications to determine the effects of sowing date, seeding rate & varieties on the yield & yield components of rice....

A range of DLC, Si-DLC, N-DLC and F-DLC films were prepared using ?PECVD ?with various film thicknesses (100-200) nm. The simplest amino acid ??“Glycine” is used as a model biological compound to ?investigate surface adsorption ?phenomena. Following exposure to solutions ?containing glycine, surface characteristic has been ?...

Pesticide usage has become an essential component of modern age agriculture. Their applications for the protection of crops through the pests, insects, mites, ticks and weeds are increasing steadily. The Pyrethroids constitute about twenty five percent of total pesticides used worldwide....

Alkaline protease producing Baciilus spp. were isolated from natural habitats of Lahore. Thirty eight isolates exhibited the prominent zones of clearance on skim milk agar medium at pH 10. These isolates which showed best proteolytic activity were then identified. Twenty two (60 %) of the alkalophilic isolates belonged to the genus Bacillus....

A growing interest in the theory of generalized inverses and in applications of generalized inverses in such fields as engineering and statistics has stimulated an interest in teaching about generalized inverses in linear algebra courses. When A is a nonsingular matrix, the equation Ax=b has a unique solution....
