in this investigation, attempts were directed to study the inhibitive effects of nitrite and phosphate base inhibitors for the carbon steel alloy samples, which are used in an acid gas treatment process (the sulfiran® solution), in fe-edta solution. electrochemical techniques, i.e. polarization curves and electrochemical impedance spectroscopy (eis), were used to evaluate the inhibition efficie...

The use of corrosion inhibitors can effectively avoid the metals and alloys, but conventional organic/inorganic have certain toxic side effects environmental pollution problems (including some expensive reagents catalysts), prompting researchers to turn their attention research water-soluble polymer with green environment friendly low pollution. This paper reviews action mechanism inhibitors, s...

a fundamental study of scale formation of calcium carbonate (caco3) for producing oil wells hasbeen carried out. this article presents the study of the prediction of salt deposition in two differentsynthetic formation waters and investigates the effects of temperature and pressure on calciumcarbonate precipitation. the dependence of the induction period of the precipitation of calciumcarbonate ...

alzheimers disease (ad) is by far the most common cause of dementia. definite diagnosis of ad is based on pathological findings. nincds-adrda criteria, published more than 25 years ago, are commonly used for the clinical diagnosis of ad. however, considering serious shortcomings of these criteria, new criteria have been proposed. according to these new criteria, ad can be diagnosed in predement...

objective(s):in recent years, the chemistry of tetrazolo[5',1':2,3][1,3,4]thiadiazepino [7,6-b]quinolines have received considerable attention owing to their synthetic and effective biological importance which exhibits a wide variety of biological activity. as the inhibitor of aldose reductase, the aforementioned compounds may have implication in preventing complications of diabetes. ...

objective: major depression is a mood disorder that causes changes in physical activity, appetite, sleep and weight. regarding the role of zinc in the pathology of depression, the present study was aimed to investigate the effects of zinc supplementation in the treatment of this disease. methods: this study was a double-blind randomized clinical trial. forty four patients with major depression ...
