Prehistoric archaeological sites in the center of the Iranian Plateau suddenly disappeared around the end of the 4th millennium BCE. At Tepe Sialk, near Kashan, the last cultural period, namely Sialk IV - probably established around 3400 BCE after the last settlements of Sialk III6-7b - was abandoned approximately after 500 years. The material culture of this period, known as Proto-Elamite peri...

historical earthquakes play a notable role in engineering seismology. the historical kashan-sialk region, 3 km south of kashan, was surveyed in the viewpoint of historical earthquakes events. several devastating historical earthquakes, occurred in the bc time, identified based on archaeological studies and evidences gathered from field study. in this respect a variety of information, namely tim...

pain in icu patients should be managed effectively and safely. fentanyl and paracetamol are used frequently in icu. however experience using iv paracetamol in the setting of critically ill patients is limited. we evaluated the analgesic effect and adverse reactions of intravenous paracetamol compared to fentanyl in icu patients with mild to moderate pain. forty patients in a general icu were ra...

the present work describes the studies on the coordination behaviour of 4[n-(benzalidene) amino]antipyrine semicarbazone (baaps) (i), 4[n-(furfural)amino]antipyrine semicarbazone (ffaaps) (ii) and 4[n-(cinnamalidene)amino]antipyrine semicarbazone (caaps) (iii) in presence of dimethyl sulfoxide (dmso) or diphenyl sulfoxide (dpso) towards th4+ and uo22+ salts. all the complexes were isolated in n...

a simple, rapid and sensitive spectrophotometric method has been proposed for the determinationof vanadium (iv). the method is based on the catalytic effect of v (iv) on the oxidation of alkali blue bypotassium bromate at ph 4. the rate of decrease in the absorbance of alkali blue (at 572 nm) wasproportional to the concentration of v (iv) in the range of 100-6000 ng ml-1. the detection limit wa...
