the role of some ring structures in the distribution of porphyry copper deposits in south kerman porphyry copper belt is discussed. in the study area, ring structures are circular or elliptical shaped features which are partly recognized on satellite images. in this study, landsat multispectral images were used to identify ring structures in the area. the rudimentary identification stages of th...

BACKGROUND MPGN is a light-microscopic ‘‘pattern of injury’’ caused by many disorders (see Table 20). Patients commonly present with nephrotic syndrome, hypertension, glomerular hematuria, and progressive kidney dysfunction. Reduction in the serum concentration of complement components (C3 and/or C4) is commonly, but not uniformly, observed. MPGN can be further classified based on the extent an...

In January 1994, the Federal Reserve Board permitted a commercial bank to begin using a new type of computer software that dynamically reclassifies balances in its customer accounts from transaction deposits to a type of personal-saving deposit, the money market deposit account (MMDA).1 This reclassification reduces the bank’s statutory required reserves while leaving unchanged its customers’ p...

Side scan sonar in low-cost 'fishfinder' systems has become popular in aquatic ecology and sedimentology for imaging submerged riverbed sediment at coverages and resolutions sufficient to relate bed texture to grain-size. Traditional methods to map bed texture (i.e. physical samples) are relatively high-cost and low spatial coverage compared to sonar, which can continuously image several kilome...

The term "Carlin-type" deposit has been applied to a number of low-grade, sedimentary rock-hosted gold deposits that have been discovered and brought into production in the western United States since the 1960s. Carlin-type deposits are characterized by replacement of carbonate and silty carbonate rocks by silica, pyrite, barite, various arsenic, mercury, antimony, and thallium minerals and by ...

The Cretaceous deposits in Morakan, located in the northeast of Khoy, a town in western Azerbaijan province, Iran, are primarily made up of carbonate rocks. These deposits, which are of 717 meters thick, lie on the clastic facies of Jurassic and are covered with beneath the pelagic beds of the Upper Cretaceous. To investigate the facies, sedimentary environment and sequential stratigraphy of th...

The Atacama Desert, northern Chile, is one of the driest deserts on Earth and, as such, a natural laboratory to explore the limits of life and the strategies evolved by microorganisms to adapt to extreme environments. Here we report the exceptional adaptation strategies of chlorophototrophic and eukaryotic algae, and chlorophototrophic and prokaryotic cyanobacteria to the hyperarid and extremel...

An increase in the ability to timely meet commitments which will be due in the near future is a prerequisite for the survival of banks. Hence, the correct and optimal management of liquidity is an important affair that banks should perform. The present study aimed mainly to test the management of asset-liability and liquidity trap in the Credit Institute for Development. The research is applied...

A 71-year-old man with hypertension and diabetes mellitus presented with proteinuria. Laboratory data showed proteinuria of 3.1 g/g creatinine, serum albumin of 3.5 g/dL and serum creatinine of 1.03 mg/dL without autoantibodies. A renal biopsy revealed segmental granular IgG depositions on glomerular capillary walls. Electron microscopy showed segmentally subepithelial, intramembranous and mesa...

Conodonts are the most important fossil remains from the largest Phanerozoic extinction as well as the mass extinction of the late Paleozoic and could be used for exact dating during this period. Triassic deposits located in the Elikah Formation contain exposures in most of the Alborz sections as well as the Zal section in northwestern Iran. In this study, the Elikah Formation was investigated ...
