985 The Hanford Site in south-central Washington State produced plutonium for the USDOE weapons program from 1943 to 1989. Plutonium (Pu) production involved the fi ssion of uranium fuels using nine nuclear reactors along the Columbia River, followed by the extraction and concentration of trace product Pu through chemically intensive processing regimes performed in the central portion of the si...

production of new hybrids is important for growing aquaculture and protecting wild stocks of fish species. a hybrid between female asp × male kutum ( leuciscus aspius ♀ × rutilus frisii ♂) was produced and its growth performance was monitored in two rearing systems for 55 days. the fish held in earthen ponds exhibited higher performance compared to those held in concrete tanks. the results also...

The assessment of response of composite seismic force resisting systems requires accurate nonlinear formulations for the composite members. In this work, reporting the first phase of a NEES project, a three-dimensional distributed plasticity formulation is presented for both circular and rectangular composite concrete-filled steel tubes (CFTs) that includes new constitutive models for the concr...

Between November 1994 and October 1996 a total of 12 samples were collected in order to characterise wastes discharged from the Frutarom complex. The study focused on two principal discharge pipes, one in front of the VCM tanks and a second shorter pipe discharging in front of the main plant. Discharges from this second pipeline had been discontinued by 1996. In 1994 a third discharge, arising ...
