in order to recognize isfahan weather types, in this research 22 variables including temperature, precipitation, atmospheric humidity and wind were studied in isfahan synoptic station from dey,11th,1339(january,1st,1960) to dey,11th,1383 (december,31st,2004). a cluster analysis on the euclidean distance of standardized matrix of data and linking days on the basis of ward method showed that isfa...

This paper modeled heating air of a room through examining free convection in a 3D chamber. The chamber had cold and hot sources with Tc and Th temperatures, respectively. Its other walls were adiabatic. This study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. To conduct the st...

In 30 patient with single cold thyroid nodule and normal thyroid function tests, 99mTc-MIBI scan is performed. The nodules are divided to hot (10), Warm (12) and cold (8). FNA reported papillary Ca in 4, suspicious follicular neoplasm in 3 and 23 benign lesions. 7 patients were operated on and had final pathology reports (4 papillary Ca and 3 benign lesions). All the nodules with no MIBI ...

background: labor pain is one of the severest pains that cause many women request cesarean section for fear of pain. thus, controlling labor pain is a major concern of maternity care. nowadays, interest in non-pharmacological pain relief methods has been increased because of their lower side effects. the effects of discrete heat and cold on decreasing labor pain have been reported but there was...

   A low carbon Al-killed Ti-added steel was produced in Mobarakeh Steel Complex in Iran. Mechanical properties and microstructural characterizations of steel in the as-cast, hot-rolled, cold-rolled and annealed conditions are presented. Dilatometery tests were carried out to measure the finishing and annealing temperatures of steel. It was found that the addition of small amounts of Ti increas...
