Test borings in the western basin of Lake Erie have revealed an extensive sub-bottom deposit of sand in a triangular region bounded by Stony Point on the mainland shore of Michigan, Middle Sister Island in Ontario, and West Sister Island in Ohio. The 550 km deposit is overlain by up to 7 m of more recent lacustrine silts and clays. The sand beds have an average thickness of 2.3 m, yielding a to...

Both uranous and uranyl minerals are present in the Centennial unconformity-type U deposit situated in the SW Athabasca Basin, Canada. At least two generations of uraninite are present (disseminated and massive), often strongly altered to coffinite, followed by minor fibrous coffinite forming in veins. Uranyl minerals, mostly uranophane with minor haiweeite precipitating in veins and in hand sa...

The purpose of this study was to investigate the clinical, laboratory, and pathologic characteristics of dense deposit disease (DDD) in Korean children and to determine whether these characteristics differ between Korean and American children with DDD. In 2010, we sent a structured protocol about DDD to pediatric nephrologists throughout Korea. The data collected were compared with previously p...

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...

The solidification behavior of droplets as well as spray-deposit of Al-4.5 wt% Cu alloy is simulated by modeling based on heat flow analysis. The model incorporates droplet dynamics and their thermal states during atomization process. The resultant spray enthalpy is used to analyze heat flow during solidification of the spray deposit. The effect of process variables like atomization pressure, m...
