The goal of this study was to determine the removal efficiencies of chromium, copper, lead, nickel, and zinc from raw wastewater by chemically enhanced primary treatment (CEPT) and to attain a total suspended solids removal goal of 80%. Operating parameters and chemical doses were optimized by bench-scale tests. Locally obtained raw wastewater samples were spiked with heavy metal solutions to o...
To determine the effects of cobalt chloride on human submandibular gland cells, HSG cells were exposed to various concentrations of cobalt chloride. Cobalt chloride induced cytotoxicity and cell death in HSG cells as determined by phase-contrast microscopy and WST-1 cell viability assay. By using the Hoechst 33342 staining, marked nuclear condensation and fragmentation of chromatin were observe...
The Lewis acid-mediated reactions of allene-ene compounds, derived from 3-methylcitronellal or dimethyl malonate, were carried out using various Lewis acids such as ethylaluminum dichloride, diethylaluminum chloride, titanium chloride, zinc chloride etherate, or boron trifluoride etherate, affording unexpectedly intramolecular [2+2]cycloaddition products under some particular reaction condition...
Objective Metals can cause male infertility through affection of spermatogenesis and sperm quality. Strong evidences confirm that male infertility in metal-exposed humans is mediated via various mechanisms such as production of reactive oxygen species (ROS). Flavonoids have antioxidant and metal chelating properties which make them suitable candidates for neutralizing adverse effects of metals ...
Revision: 4/95 Process/Product: Mechanical Paint Stripping Process Code: ID-01-01, ID-01-99 Substitute for: Solvent Stripping Waste Stream: Aircraft Chemical Stripping and Paint Wastes Applicable EPA Hazardous Waste Codes: D007, D008, D035 Applicable EPCRA Targeted Constituents: Toluene, Xylene, Methyl Ethyl Ketone, Acetone, n-Butyl Alcohol, Lead, Chromium, Zinc Compounds, Phenols, Cloroacetic ...
Objective: To see the dose dependent effects of zinc chloride on the short-term and long-term memory in a shuttle box (rats). Methodology: Six pair adult wistar rats were taken for this experiment. One group of pregnant rats received a daily oral dose of 20mg/kg Zn as zinc chloride and the remaining groups received a daily oral dose of (30, 50, 70,100mg/kg) zinc chloride for two weeks by gavage...

Zinc electroplating was used to enhance corrosion resistance of porous metal injection molded 440C stainless steel. Controlled porosity achieved by the powder space holder technique and using sodium chloride as a material. The internal pore structure deposited zinc with three different electrolytes acetate, sulfate, chloride. Our results show that all depositions on samples significantly improv...
introduction: zinc is an essential trace element that plays an important role in synaptic plasticity and modulating the activity of cns and involve in learning and memory. synaptic vesicle zinc in the hippocampus area exerting modulatory effects on nmda glutamate receptor. method: in this experiment the effects of nmda agonist and antagonist administration intra hippocampus on passive avoidance...
