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...

Background: This study aimed to investigate different methods used to provide necessary supplementations for pregnant women and obtain reliable data about the general status of health promotion during pregnancy. Methods: This descriptive, cross-sectional study was conducted on 401 pregnant women referring to different women’s hospitals of Tabriz, including Alzahra, Taleghani, 29-Bahman, Zakariy...

OBJECTIVE The objective of the present study was to investigate the effect of epipregnanolone on the influence of neurosteroids on the development of rapid tolerance to the motor impairing and hypothermic effects of ethanol. METHOD Experiment 1: on Day 1 groups of mice were pretreated with saline or with epipregnanolone. After 30 min each group was further divided in subgroups that received e...

zno nanoparticles were synthesized by a microwave-assisted chemical method. zno nanostructures were synthesized via a fast reaction between zinc acetate and ammonia at presence citric acid and other effective agents in chemical procedure. nanostructures were characterized by x-ray diffraction , scanning electron microscopy. seed yield and seed quality of safflower grown under drought stress. th...

Incubation at 37#{176}Cfor 30 mm or the addition of CaCl2 (5 mM) generated platelet-clumping activity in citrated plasma and EDTA plasma previously acidified to pH 5.5 and in which heparin was added to give a concentration of 0.5 mg/mi. Similar treatment could not produce platelet-clumping activity in saline or denatured plasma that had been heated to 56#{176}C.Heparin, chondroitin sulfate B, o...

UNLABELLED The objective of this study was to evaluate usage possibilities of magnesium sulfate in anesthesiology. METHODOLOGY In Clinic of Cardiac Surgery, Kaunas University of Medicine magnesium sulfate was started for use as an adjuvant to anesthetics. For anesthesia it was used in 20 cases. This review article presents the methodology based on which the magnesium sulfate anesthesia was gi...

H2S emissions from landfill sites resulting from sulfate reduction has become a serious human health and ecological safety issue. This study investigated H2S emission behavior and sulfate metabolism occurring in simulated landfills under different operating conditions. Under aerobic conditions, great attenuation of the original sulfate content (from around 6000 mg kg-1 dropped to below 800 mg k...

The structure of synthetic disodium magnesium disulfate decahydrate at 180 K consists of alternating layers of water-coordinated [Mg(H(2)O)(6)](2+) octahedra and [Na(2)(SO(4))(2)(H(2)O)(4)](2-) sheets, parallel to [100]. The [Mg(H(2)O)(6)](2+) octahedra are joined to one another by a single hydrogen bond, the other hydrogen bonds being involved in inter-layer linkage. The Mg(2+) cation occupies...
