in order to reduce herbicide utilization, a 3-year field experiment was carried out with integration of mechanical and chemical weed control methods; in mechanical method, three types of blades (curred- bed knife, square- turn knife and sweep) were used. chemical control was done with chloridazon (wp 80%) and desmedipham (ec 15.7%) in two spraying sheme: once band sparying with 2 l h-1 & twice ...

the pharmacokinetics of cefpirome after a single intravenous injection of 10 mg.kg -1 was studied in febrile cross-bred calves. e. coli endotoxin was administered intravenously to induce fever in calves. blood samples were collected at different time intervals and cefpirome levels were estimated by using microbiological assay technique. based on the plasma drug levels, the pharmacokinetic param...

in-vitro labeling of rbc with 99mtc is an intricate procedure and there is always a need foran alternate blood pool imaging agent. the aim of this study was to prepare an effective nanosized liposome (nls) similar to human rbc for blood pool scintigraphy. this study formulatespeg-nls and non-peg-nls using film method plus high pressure homogenization technique.biodistribution studies were perfo...

The medieval banks of continental Europe facilitated trade by serving as payment intermediaries. Depositors commonly would pay one another by transferring bank balances with the aid of overdraft credit. We model this process in an environment of intermediate good exchange with incomplete contract enforcement. Our model suggests that the early banks were capable of accessing the “netting credit”...
