the cheshin meta-calcareous rocks (permo triassic) in southeast hamedan outcrop in association with a variety of pelitic schists and hornfels rocks. the intrusion of the alvand batholith (jurassic age) into pelitic and calcareous host rocks has produced metamorphic rocks in the hamedan area (cheshin village). on the basis of the dominance of calcite/dolomite, silicate and ore minerals, the calc...

An instrument fo r recording optical absorbance of s ingle living cells was demonstrated . The apparatus is based on a grating polychromator and measures absorbance simultaneously at several different wavelengths. It was designed for high-resolution recording while leaving cells accessible to multiple microelectrode impalement. The instrument has been used on nerve cells containing the indicato...

Obsidians found in silicic domes and rhyolitic tuffs are an ideal system to understand the formation conditions of calc-alkaline felsic magmas. The Optical Absorption Electron Paramagnetic Resonance (EPR) spectroscopic data presented this study demonstrate that Fe-speciation obsidians is different from observed other geological glasses (e.g., basaltic glasses) or synthetic Fe-bearing silicate g...

A. Kalup, S. Zlá, M. Kawuloková, J. Dobrovská, B. Smetana, VŠB-TU Ostrava, FMME, Ostrava, Czech Republic Three real grades of nickel super-alloys (IN 713LC, IN 738LC and IN 792-5A) were investigated and values of temperatures of phase transformations and latent heats of melting were obtained. All investigated quantities are very important for thermodynamic and kinetic modelling. Moreover, these...
