امروزه کاربرد فرآیندهای غشایی در صنعت، جهت تصفیه، تغلیظ و بازیابی مواد روز بروز افزایش می یابد. تقطیر غشایی (md) یکی از تکنولوژیهای جدید در زمره فرایندهای غشایی می باشد. نیرو محرکه این فرآیند، اختلاف فشار جزئی دو طرف غشاء ناشی از اختلاف دما، می باشد. در این فرآیند خوراک ابتدا گرم می شود و سپس بخارات جزء عبوری از درون حفرات یک غشاء میکروحفره و آبگریز عبور می کند. بخارات در طرف دیگر غشاء مایع می ...

Rotary ATPases are involved in numerous physiological processes, with the three distinct types (F/A/V-ATPases) sharing functional properties and structural features. The basic mechanism involves the counter rotation of two motors, a soluble ATP hydrolyzing/synthesizing domain and a membrane-embedded ion pump connected through a central rotor axle and a stator complex. Within the A/V-ATPase fami...

In this paper, we introduce a calculus of communicating systems which allows for the expression and analysis of timing constraints, for example as is important for real-time processes. We present the language, along with its formal semantics, and derive algebraic laws for reasoning about processes in the language. Though the core language is simple, we show that the language has several powerfu...

The incidence of calcium oxalate stone in men is higher than that in women. We evaluated the association between the androgen receptor (AR) and urinary oxalate excretion using Cre-floxed male androgen receptor-knockout (ARKO) mice (ARL−/Y) and floxed mice (ARL+/Y) as control. Fourteen-week-old ARL−/Y and ARL+/Y mice were fed distilled water. Drinking water was then swapped for 0.5% ethylene gly...

ZnO nanorods and nanodisks were synthesized by solution process using zinc chloride as starting material. The morphology of ZnO crystal changed greatly depending on the concentrations of Zn(2+) ion and ethylene glycohol (EG) additive in the solution. The effect of thermal treatment on the morphology was investigated. Photocatalytic activities of plate-like Zn(5)(OH)(8)Cl(2) . H(2)O and rod-like...

introduction: eugenol (eg), a compound extracted from clove tree, is known for its anti- anaphylactic, anti-inflammation, antiseptic, antibacterial and analgesic properties as well as chain breaking antioxidant in inhibition of lipid peroxidation. retinoic acid (ra), one of the synthetic derivatives of vitamin a, has been frequently used for treatment of face acne. in our studies eg was used to...

Background. The importance of physical activity (PA) for maintaining and improving health status increases with each passing day. Objectives. The present study aimed to examine the effects of PA and nutritional education programs applied to 12th-grade students on body mass index (BMI), PA level, and eating habits during the COVID-19 pandemic. Methods. One hundred fifty-nine 12th grade student...
