Long Term Satellite Global, Beam and Diffuse Irradiance Validation

Long -Term Outcome Therapy of Toxic Diffuse Goiter in Tehran

SUMMARY In order to evaluate the long-ter m effects of antithyroids and ahlative therapy on patients with toxic diffuse goiter (TDG) in an iodine deficient region, 206 patients were studied in Tehran. Hyperthyroidism recurred in 50%, of 80 patients treated with Methimazole (MMI), from one week to 48 months after cessation of therapy. Another 40 patients remained in remission. Of 102 patients t...

Comparison and validation of three global-to-beam irradiance models against ground measurements

The study presents a comparison and validation of 3 state of the art global to beam irradiance conversion models against ground measurements from 22 sites covering a wide range of latitudes, altitudes and climates. One of the 3 models takes into account a climatic turbidity and gives slightly betters results in term of bias and precision. On a hourly time step basis, the validation on over 100 ...

Long-Term Detection of Global Vegetation Phenology from Satellite Instruments

Determination of the Effective Accuracy of Satellite-derived Global, Direct and Diffuse Irradiance in the Central United States

Using high precision irradiance data from the Southern Great Plains ARM extended facility network [1], we confirm results of initial efforts by the authors to quantify the effective -intrinsic -accuracy of hourly global irradiances derived from geostationary satellite observations. We extend this initial analysis to other components –direct and diffuse – as well as other time steps – 1-minute a...

the effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus

از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
