At present, the cooling of all the hot underground operations at Impala is achieved by providing refrigerated air from surface. However, the depth of a number of planned projects will approach 2 000 m below surface and other future proposed operations will extend to even deeper levels. Obviously these depths will approach the horizon where acceptable underground conditions can no longer be achi...

Regularized Generalized Canonical Correlation Analysis (RGCCA) is a component-based approach which aims at studying the relationship between several blocks of numerical variables. In this paper we propose a method called Symbolic Generalized Canonical Correlation Analysis (Symbolic GCCA) that extends RGCCA to symbolic data. It is a versatile tool for multi-block data analysis that can deal with...

we investigated the issue of noise pollution in the bidboland gas refineryby noise measurement and surveys. the bidboland gas refinery has several process units.the sound pressure levels were measured at several places, such as units of 200, 300,400, 500, boiler, powerhouse area, cooling towers pumps, and maintenance area, and thecorresponding noise maps were produced by using sound plan softwa...

The rapid cooling (RC) response in muscle is an increase in cytoplasmic Ca2+ concentration ([Ca2+]i) that is probably caused by Ca2+ release from the sarcoplasmic reticulum (SR). However, the molecular bases of this response have not been completely elucidated. Three different isoforms of the SR Ca2+ release channels, or ryanodine receptors (RyRs), have been isolated (RyR1, RyR2, and RyR3). In ...

Right ventricular adaptation to the increased pulmonary arterial load is a key determinant of outcomes in pulmonary hypertension (PH). Pulmonary vascular resistance (PVR) and total arterial compliance (C) quantify resistive and elastic properties of pulmonary arteries that modulate the steady and pulsatile components of pulmonary arterial load, respectively. PVR is commonly calculated as transp...

Radiative heat transfer (RHT) between macroscopic bodies at separations that are much smaller than the thermal wavelength is ruled by evanescent electromagnetic modes and can be orders of magnitude more efficient than its far-field counterpart, which is described by the Stefan-Boltzmann law. In this Letter, we present a microscopic theory of RHT in van der Waals stacks comprising graphene and a...
