qahr-abad fluorite deposit is located 58 km southeast of saqqez, in northwestern kordestan province and in northern end of sanandaj-sirjan zone. the factors such as change in physicochemical conditions of mineralization environment (ph and eh), variation in pressure and temperature, alteration, metamorphism, oxidation of organic matters, adsorption, activity and solubility of associated anions,...

a total of 40 samples from carbonates and 8 samples from silicate rocks were analyzed from the sangan iron skarn deposit to examine behavior of the oxygen and carbon isotopes. the higher values of ?18o are from metamorphic calcite and dolomite and lower ones are from granitic rocks. although the ?18o and ?13c values of calcite and dolomite in marble yield the highest values in the sangan deposi...

zafarabad iron deposit is located northwest of divandareh, in the northern margin of sanandaj-sirjan plutonic-metamorphic zone. the deposit is in lentoid to tubular shape, within a shear zone and occrrued in host rocks of calc-schist and limestone. magnetite with massive, cataclastic and replacement textures are the main phases, while pyrite and other sulfide minerals are found. major and trace...

It is important to conduct a comprehensive situational analysis when considering the introduction of a deposit insurance system or when planning to alter an existing deposit protection arrangement. In conducting such an analysis, the economic and institutional conditions and their effect on the alternatives available for a deposit insurance system must be considered. Among the conditions that s...

This paper studies the optimal determination of deposit insurance when bank runs are possible. We show that welfare impact changes in level coverage can be generally expressed terms a small number sufficient statistics, which include losses specific scenarios and probability failure. characterize wedges determine ex ante regulation, map to asset- liability-side regulation. demonstrate how emplo...

Descemet stripping automated endothelial keratoplasty (DSAEK) is a new treatment option for corneal endothelial dysfunction. Compared with penetrating keratoplasty, DSAEK is less invasive and leads to more rapid visual recovery. The most common complications after DSAEK described in the literature are graft detachment and/or dislocation, rejection, epithelial ingrowth, and pupillary block, all ...
