the use of satellite data in an estimation of air temperature (ta) near the earth’s surface has turned into an effective way for a large area of high spatial and temporal resolution. throughout the present study, artificial neural network (ann) as well as m5 model tree were employed to estimate ta in khuzestan province (south west of iran), using satellite remotely sensed land surface temperatu...

We estimate “CEO style” wage equations using two longitudinal matched employeremployee data sets. We develop a model in which the wages of all employees in a ...rm are linked to those of top management, which generates speci...c empirical implications that have already been tested on CEOs.

We tried to clarify the applicability of "utility" for the evaluation of patient's QOL with gastric cancer after chemotherapy and attempted to compare differences in QOL after treatment with the oral antitumor agent TS-1 or with a conventional injectable combination. Three items, moving activity, pain, and gastrointestinal symptoms, were employed as indicators of patient QOL, and then the asses...

purpose: to compare the effects of standard tissue saving method and personalized techniques of photorefractive keratectomy (prk) on aberration changes in fellow eyes. methods: this randomized controlled trial was performed on patients who were referred to isfahan parsian clinic during 2007. after a comprehensive ophthalmologic examination, prk was randomly performed using tissue saving (ts) te...
