A new anaerobic reactor, Jet-loop anaerobic fluidized bed (JLAFB), was designed for treating high-sulfate wastewater. The treatment characteristics, including the effect of influent COD/SO4(2-) ratio and alkalinity and sulfide inhibition in reactors, were discussed for a JLAFB and a general anaerobic fluidized bed (AFB) reactor used as sulfate-reducing phase and methane-producing phase, respect...

Submicron aerosol physical and chemical properties in remote marine air were measured from aircraft over the Southeast Pacific during VOCALS-REx in 2008 and the North Pacific during IMPEX in 2006, and aboard a ship in the Equatorial Pacific in 2009. A High Resolution – Particle Time of Flight Aerosol Mass Spectrometer (HR-ToFAMS) measured non-refractory submicron aerosol composition during all ...

Interrelationships among blood pressure (BP), sodium (Na), potassium (K), dietary protein, and serum cholesterol level (Chol) were examined in 62% (1120) of 1818 Japanese inhabitants of both sexes aged over 30 years who lived in a rural village in Japan. Fasting single-spot urine specimens were collected in the morning to measure Na, K, urea nitrogen (UN), inorganic sulfate (SO4), and creatinin...

In the reaction of zinc(II) sulfate and chloride salt 2-acetylpyridine-aminoguanidine, two types complex were obtained, i.e., [Zn(H2O)6](H2L)2(SO4)3·3H2O [Zn(L)H2O(SO4)]·H2O, depending on presence LiOAc as deprotonating agent. The physicochemical, structural, photoluminescence properties complexes examined. first complex, obtained in absence LiOAc, Schiff base had role a counter-ion its doubly ...

By measuring levels of noradrenaline (NA) and its major metabolite, 3-methoxy-4-hydroxyphenylethyleneglycol sulfate (MHPG-SO4), in various rat brain regions, the effects of angiotensin II (AT II) injected intracerebroventricularly (ICV) were investigated in non-stressed and stressed rats. Immobilization stress with a wire mesh was employed. Immobilization stress induced significant increases in...

The seasonal and spatial variability of water quality, including mercury species, was evaluated in agricultural and managed, non-agricultural wetlands in the Yolo Bypass Wildlife Area, an area managed for multiple beneficial uses including bird habitat and rice farming. The study was conducted during an 11-month period (June 2007 to April 2008) that included a summer growing season and flooded ...

FOR OSMOREGULATING vertebrates, diffusive water loss is an unavoidable consequence of living in seawater. Marine teleost fish drink seawater to offset this diffusive water loss dictated by the steep osmotic gradient between blood and the surrounding seawater, a water loss occurring mainly across the gills. Imbibed seawater is processed along the gastrointestinal tract by desalinizing the medium...

in the present study, the effects of four factors including initial sulfide concentration (mg l-1 ), agitation speed (rpm), amount of inoculums (%) and sodium concentration (mg l-1) on removal efficiency (%r) and yield of sulfate production by thioalkalivibrio versutus from synthetic spent caustic were investigated. for this purpose, experiments are designed by design of experiments (doe) and r...

Heavy metal stabilization in soil was investigated using sulfate-reducing bacteria (SRB). Samples were collected from three agricultural soils near abandoned mines, and a nine-week batch experiment performed following the classification of as ① non-sterile with SO42- (SO4), ② sterile SRB (SRBo), ③ (SS). metals extracted 0.1 N HCl or Mehlich, efficiency evaluated by comparing results to control....
