The Shotorkhosb kaolin deposit is located about 7 km southeast of Torbat-e-Heydariyeh, Khorasan Razavi Province, northeast Iran. This deposit is a part of the Khaf-Kashmar-Bardaskan metallogenic zone. Field observations and laboratory studies indicate that this deposit is a product of alteration of Eocene andesitic rocks. In this study, different analytical techniques, such as XRD, SEM-EDS, FE...
This paper analyzes the joint influence of the quality of a bank’s loan portfolio, the bank’s maturity gap and its deposit rate policy on the value of deposit insurance in an arbitrage-free Basel II consistent framework. We develop and apply a two-stage structural model of a bank where deposit insurance is a European put option on the loan portfolio, the default of each loan is driven by the bo...
THE fact that pneumonia mortality is higher in urban areas suggests that air pollution has some effect upon the incidence of this disease. To test such a possibility, pneumonia mortality-rates were calculated for the whole populations of fifty-three cotinty and Metropolitan boroughs in England, Scotland, and Wales, from the Registrar General's annual statistical reviews for the 5-year period 19...
Rock unites which are exposed in Tak-I mine area are: Taknar formation (Ordovician), Mid-late Paleozoic and younger intrusive rocks. Taknar formation consists of sericite schist, chlorite schist, chlorite-sericite schist and some meta-diabase- gabbro-diorite. Taknar Polymetal (Cu-Zn-Au-Ag-Pb) Massive sulfide deposit formed at certain horizon of Taknar formation. Three style of mineralization ar...
The Tang Zagh iron deposit is located about 117 km Northeast of Bandar Abbas, Hormozgan Province in the structural folded-thrusted zone of the Zagros basin. Iron mineralization occurs in the form of iron oxides (hematite) within the salt dome and/or in fractures and between the layers of the younger strata with the Tertiary age. Based on the microscopic studies, dolomitic fragments of the host ...
Band-e-Ghichy copper deposit is located in the northern margin of the Central Iran structural zone, about 120 km south of Shahrood and 70 km south east of Torud. Copper mineralization occurred in the rock units including sandstone, conglomerate and siltstone with the Oligocene age. Mineralization has occurred in the form of stratiform (syngenetic), stratabound (epigenetic) and supergen (the sur...
Scientific journals are more and more published electronically. Gradually the amount of e-books increases and on Internet a vast amount of digital information is being published. Electronic publishing offers major opportunities for dissemination and for access but at the same time imposes new challenges on national libraries and other deposit institutes in charge of preserving countries’ cultur...
This paper presents an empirical examination of the effects of both deposit market competition and of wholesale funding on bank risk simultaneously. The traditional view of the relation between competition and risk has focused on the disciplining role of the charter value. In this project we argue that if the structure of bank liabilities and the costs of retail and wholesale funding are jointl...
A brief overview on boiler tubes ash deposit characterization and thermophysical properties of deposits are given. The structure of an ash deposit on the heat exchange surface of a boiler is usually non-uniform. The thickness of the deposit increases with time and during this process chemical reactions and sintering of ash particles may lead to structural changes. Therefore the thermal conducti...
