Adsorption of arsenic and chromium by mixed magnetite and maghemite nanoparticles from aqueous solution is a promising technology. In the present batch experimental study, a commercially grade nano-size 'magnetite', later identified in laboratory characterization to be mixed magnetite-maghemite nanoparticles, was used in the uptake of arsenic and chromium from different water samples. The inten...

Hexavalent chromium is a bio accumulative toxic metal in water and fish. It enters aquaculture ponds mainly through anthropogenic sources. Hexavalent chromium concentrations and its effects on the morphology and behavior of Clarias gariepinus were investigated from four aquaculture ponds for 12 weeks. Chromium was measured using diphenyl carbohdrazide method; alkalinity and hardness were measur...

Three hundred and twenty four one day old mixed sex broiler chicks were assigned at random into 9 treatment groups. The experimental design was a 3×3 factorial arrangement. During the starter period (week 1-3), chicks were fed ad libitum. A cornsoybean meal based diet contained 23% crude protein, 3,200 kcal/kg metabolizable energy (NRC, 1994), and supplemented with organic or inorganic forms of...

hydroponic experiments were performed to exam the dynamic change of endogenous proline in rice seedlings exposed to potassium chromate chromium (vi) or chromium nitrate chromium (iii). although accumulation of both chromium species in rice seedlings was obvious, more chromium was detected in plant tissues of rice seedlings exposed to chromium (iii) than those in chromium (vi), majority being in...

Background: Hyperglycemia may induce endothelial dysfunction. Chromium Supplementation enhances endothelial relaxation and may improve endothelial dysfunction. Present study was planned to evaluate effect of proprietary chromium complex(PPC) and its individual components on endothelial dysfunction and lipid profile in type 2diabetics. Methodology: Study was done in two parts. In part I, PPC 400...

In this study, the effects of diffusion on gold-chromium film durability was determined from interfacial fracture energy measurements on laboratory samples aged to simulate long term service. The samples were prepared by sputter deposition of gold films and chromium adhesive layers on sapphire substrates. Some films were left in the as-deposited condition while others were given an accelerated ...

Prima facie evidence is presented that, where naturally occuring chromium in water supplies occurs, it is associated with a lower prevalence of diabetes and a lower incidence of mortality from vascular occlusive disease. It is postulated that increased prevalence of such disease in a population is associated with chromium 3 deprivation. This results from con­ sumption of highly refined cereal f...

ARTH 431/631-010 SEM: ARTS & ARCHITECTURE OF PENNSYLVANIA GERMANS The distinctive regional culture of the Pennsylvania-Germans in the 18th and 19th centuries examined through the study of their cultural landscapes, houses and other buildings, decorative arts, gravestones, and manuscript traditions. Explores themes of ethnic aesthetic expression, sectarian culture, community identity, and the fu...

Several plants are used for their decorative effect during winter holidays. This review explores the toxic reputation and proposed management for exposures to several of those, namely poinsettia (Euphorbia pulcherrima), English holly (Ilex aquifolium), American holly (Ilex opaca), bittersweet (Solanum dulcamara), Jerusalem cherry (Solanum pseudocapsicum), American mistletoe (Phoradendron seroti...
