Strain GR-1 is one of several recently isolated bacterial species that are able to respire by using chlorate or perchlorate as the terminal electron acceptor. The organism performs a complete reduction of chlorate or perchlorate to chloride and oxygen, with the intermediate formation of chlorite. This study describes the purification and characterization of the key enzyme of the reductive pathw...

this study carried out in a factorial layout on completely randomaized block design with three replications, to evaluate the above- and below- ground competition between sesame (sesamum indicum) and pigweed (amaranthus retroflexus), and their impacts on sesame yield and yield component. the experimental treatments were all combination of crop-weed competition (shoot competition, root competitio...

The thermal time, expressed in accumulated growing degree-days (AGDD), was used as a predictor to describe and simulate the independent growth of two pasture crops, Lolium perenne L. Bromus valdivianus Phil. Two sinusoidal models (four-parameter Logistic Gompertz) were applied variables (total leaf blade length per tiller—LBL, herbage mass—AHM). nutritive value pastures predicted modeled using ...

broiler carcasses are considered to be the major source of salmonella detection and enumeration of salmonella in this product are two criteria for evaluation of hygienic quality of the slaughterhouses and the product itself. in this study, contamination of broiler carcasses produced in poultry industrial slaughterhouses in tehran province was assessed using three tube mpn methods. according to ...

Many per-flow scheduling algorithms have been proposed to provide rate and delay guarantees to flows. It is often argued that the need for maintaining per-flow state and performing per-packet classification seriously limits the scalability of routers that employ such per-flow scheduling algorithms. Consequently, design of algorithms that can provide per-flow rate and delay guarantees without re...
