Transformers in power plants act as intermediaries between the power plant and the power grid, which are affected by electrical stresses such as switching, thermal stresses such as overload and arc, and chemical reactions in the dielectric oil. Acid and moisture components cause deterioration of transformer oil and paper insulation. Condition assessment of transformers is a method to predict an...
Phenothiazines are known to be among the compounds that reverse or modulate the multidrug resistance (MDR) of cancer cells. There is much evidence that the interactions of these reversal agents with the lipid phase of the plasma membrane are involved in the mechanism of MDR reversal. In this study, two parameters of a set of commercial phenothiazines were estimated: the phosphatidylocholine ves...

MÉTODOS: Análise temporal e estudo de tendência por regressão polinomial de suicídios na população acima de dez anos no Brasil e no Estado do Rio de Janeiro de 1980 a 2006. Os dados foram extraídos do Sistema de Informações sobre Mortalidade e as taxas, calculadas segundo sexo e faixa etária, considerando-se a população residente fornecida pelo Datasus por 100 mil habitantes. Para os anos de 19...
پیشنهاد های زیادی توسط محققین برای کاهش انتشار دی اکسید کربن مطرح و اجرا شده است . یکی از بهترین روش ها، ذخیره سازی در ساختار های زمین شناختی زیر زمینی می باشد. ذخیره سازی وتزریق دی اکسید کربن در مخازن خالی نفت و گاز ، مخازن نفت و گاز برای eor و egr ،سفره های آب شور ، بستر های زغال سنگی و اقیانوس ها انجام می گیرد.کشور ایران دارای سازند های بزرگ نفتی و گازی می باشد.از این رو می توان از آن ها برا...
a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
