Legal deposit processes for printed material has been established for centuries [1]. However, the same processes are not necessarily applicable in the case of non-print material such as electronic books. Legal deposit of electronic publications is subject to numerous, often unique challenges such as the legal deposit process, legal issues and infrastructure required. Some of these have been rep...
Measuring value and interest rate risk in retail financial markets such as the market for consumer deposits has proven to be a very difficult problem for financial firms. Standard models of value and interest rate risk (duration), based on the competitive market paradigm, are inappropriate in retail markets characterized by sluggish price and quantity behavior. Although the penetration of sophi...
Light and electron microscopic studies of corn plants (Zea mays L.) exposed to Pb in hydroponic solution showed that the roots generally accumulated a surface Pb precipitate and slowly accumulated Pb crystals in the cell walls. The root surface precipitate formed without the apparent influence of any cell organelles. In contrast, Pb taken up by roots was concentrated in dictyosome vesicles. Dic...
Gardaneshir Pb–Zn deposit is hosted by dolomitic carbonates which is located in the SW Ardestan, central Iran. Ore body is stratabound type in this deposit. Primary ores in this type are composed of sphalerite, galena, barite and quartz with massive, banded, veined and disseminated structures. Evaluation of ore-grade at the Gardaneshir Pb-Zn deposit, based on chemical analysis which indicates a...
The Bozjani copper deposit is located about 30 km west of Fariman city, Khorasan Razavi Province. Host rocks to mineralization are mostly pridotites and basalts of Fariman ophiolitic sequence. Ore body consists of two parts: lower and upper. Lower part has formed a stringer of primary sulfides as stockwork, veinlets, and disseminated. Uppermost part has lenticular shaped dominated by ribbon-lik...
The Application of Artificial Neural Networks to Ore Reserve Estimation at Choghart Iron Ore Deposit
Geo-statistical methods for reserve estimation are difficult to use when stationary conditions are not satisfied. Artificial Neural Networks (ANNs) provide an alternative to geo-statistical techniques while considerably reducing the processing time required for development and application. In this paper the ANNs was applied to the Choghart iron ore deposit in Yazd province of Iran. Initially, a...
The Esfezar bentonite deposit is located 50 km east of Birjand, in south Khorasan Province and as a part of eastern boundary of lut Block. This deposit is a diagenetic bentonite type, because of its layering, existence of gypsum between bentonite layers, and expanded shape. Petrography and chemical analysis of host rocks in Esfezar bentonite deposit indicate that they are mainly of dacite and ...
The Robat-Paein barite deposit is located about 30 Km northwest of Khomein city, in the Sanandajـ Sirjan zone. The Lower Cretaceous carbonate sequences are the host rock of barite mineralization in the Robat-Paein deposit. These carbonate sequences consist mainly of massive bedded orbitolina-bearing limestone (undergone dolomitization in some areas) as well as marl, shale and thinly bedded l...
introduction the shahrestanak mn deposit is located in southern qom province, 12 km southwest of the city of kahak. based on geological-structural divisions of iran, the deposit belongs to central volcanic belt or urumieh-dokhtar zone. the venarch deposit is one the most important known manganese deposits in iran. the sharestanak and venarch deposits are spatially and temporally related to each...
With bank-level data from 81 developing countries, the paper shows that increased foreign bank presence is associated with increased reliance on non-deposit based funding, which leads to higher interest rate spreads, less credit to the private sector, and higher volatility in bank loans. Foreign bank entry significantly reduces domestic banks’ share of deposits while foreign banks typically all...
