abstract in recent years, automatic weather stations have been widely used for recording meteorological data in different time scales. therefore the accurate estimation of eto by combination equations can be evaluated using these set of short time scales data. daily eto can also be calculated by summation of hourly eto values. the purpose of this study is to compare the eto values estimated by ...

BACKGROUND The aim of this study was to compare plasma cortisol concentration during anesthesia of children with congenital heart disease who received dexmedetomidine (DEX) with those who received etomidate (ETO). MATERIAL AND METHODS We recruited 99 ASA physical status II-III pediatric patients scheduled for congenital heart disease (CHD) corrective surgery and divided into them into 3 group...

AIM To study the mechanism underlying the difference in physical dependence potential of morphine (Mor), methadone (Met), buprenorphine (Bup), etorphine (Eto), and dihydroetorphine (DHE). METHODS Adenylate cyclase of NG108-15 cells were used for studying the effects of different opiates on cAMP second messenger system. RESULTS Bup, DHE, and Eto were distinct from Mor in naloxone-precipitate...

Accurately quantifying evapotranspiration (ET) is essential for modelling regional-scale ecosystem water balances. This study assembled an ET data set estimated from eddy flux and sapflow measurements for 13 ecosystems across a large climatic and management gradient from the United States, China, and Australia. Our objectives were to determine the relationships among monthly measured actual ET ...

Ethylene oxide (EtO) is a potent DNA-alkylating agent which has been shown to induce sister chromatid exchanges (SCE) in the peripheral blood lymphocytes of exposed workers. To study further the persistence of EtO-induced SCE, we have examined lymphocytes from a group of cynomolgus monkeys exposed to EtO in control, 50-ppm, and 100-ppm concentrations for 7 h/day, 5 days/week over the years 1979...

یکی از پیش­نیازهای اساسی بهبود مدیریت مصرف آب در مزرعه، تخمین دقیق میزان آب مصرفی گیاه است. برآورد دقیق مقدار آبی که صرف تبخیر- تعرق گیاهی می­شود، یکی از عوامل مهم برنامه­ریزی جهت توسعه کشاورزی و افزایش محصول است. روش پنمن- مانتیث فائو (FPM) به‌عنوان استاندارد جهانی به‌منظور برآورد تبخیر- تعرق گیاه مرجع (ETo) و نیز برای ارزیابی دیگر روش­های تخمین ETo  پیشنهاد گردیده که نیازمند داده­های تابش خور...

Experiments involving ethylene oxide (ETO) have been used to support the concept of using adducts in hemoglobin as a surrogate for DNA adducts in target tissues. The relationship between repeated exposures to ETO and the formation of N-(2-hydroxyethyl)valine (HEtVal) in hemoglobin and 7-(2-hydroxyethyl)guanine (7-HEG) in DNA was investigated in male rats and mice exposed by inhalation to 0, 3, ...
