روش تبخیر نفوذی فرآیند نسبتاً جدیدی از جداسازی های غشایی است که به علت مزایای خاصی که دارد از جمله مصرف پایین انرژی، برای گوگرد زدایی از مشتقات نفتی مورد توجه خاصی قرار گرفته است. حذف ترکیبات گوگردی از مشتقات نفتی به دلایلی از جمله احتراق مواد سوختنی حاصل از نفت خام و تولید اکسیدهای گوگردی منجر به آلودگی محیط زیست می شود. به همین علت گوگرد زدایی به موضوع بسیار مهمی در پالایشگاه ها و صنایع پتروشی...

Pioglitazone belongs to the thiazolidinedione (TZD) class of antidiabetic agents, with proven efficacy in increasing insulin sensitivity and in the treatment of type 2 diabetes mellitus in humans. Pioglitazone has been proposed as a potential feed additive to reduce insulin resistance and consequently some of the metabolic disorders in transition cows. This study was aimed at determining the ph...

Clinically healthy adult black Bengal female goats were used to investigate the pharmacokinetics of closantel following intravenous administration (10 mg/kg) both in healthy and in liver damaged goats. Induction of liver damage was done by subcutaneous injection of carbontetrachloride at 0.75 mL/kg on three occasion at 48 h interval. After administration of drug, blood samples were collected in...

Abstract Solar-driven interfacial evaporators are very promising for obtaining clean water, but suffer from serious performance degradation due to salt-fouling, low evaporation rate under weak illumination and water collection rate. Here, we report highly salt-resistant all-weather with photothermal electrothermal effects based on the Janus graphene@silicone sponges opposing wettability. The ac...
