Background and Aims: Coal is a naturally occurring mineral and a large source of fossil fuel throughout the world. Its importance in Pakistan increases as other fuels, like petroleum are scares and expensive coal is abundant and cheap. Coal dust comprise of carbon, hydrogen, oxygen,nitrogen, sulphur, quartz and some traces of iron, lead and copper. These particles are not degradable and deposit...

Nitrogen oxides and carbon monoxide gases together with dust are known as the major pollutants arising during the blasting operations using the ammonium nitrate-fuel oil (ANFO) explosive at the Sungun surface mine, located in the northwest of Iran. The pollutants were monitored during some blasting operations at the mine. It was concluded that the gases and dust clouds initially went up to the ...

small amounts of native zinc have been recently identified in samples from the oxidized zones of the lead-zinc-silver deposits of the Keno Hill Galena Hill area, Yukon. Most of the zinc seen came from the oxidized lodes at the Elsa mine. The r-ray pattern of the natural mineral agrees with the data for the zinc standard as published by Swanson & Tatge (1953) of the National Bureau of Standards,...

We investigate the boost in sentiment performance by taking coreference information into account. We mine user generated content for market research. Frequent topic shifts in the data lead us to investigate sentiment algorithms which look at a window of text around topic key phrases. We describe and implement a lightweight sentiment analysis system and show how the system performance can be imp...

Doing large-scale genomics experiments can be expensive, and so experimenters want to get the most information out of each experiment. To this end the Maximally Informative Next Experiment (MINE) criterion for experimental design was developed. Here we explore this idea in a simplified context, the linear model. Four variations of the MINE method for the linear model were created: MINE-like, MI...

the present study represents a first insight into the draa lasfar min (marrakech - morocco) to assess the degree of polymetallic pollution caused by anthropogenic activities (like mine extraction) and consequently the possible diffusion of heavy metals and to predict the risk of their mobility in the surroundings of the mine area. the edaphologic parameters ph and electrical conductivity (ec) w...

Sponsored by Defense Threat Reduction Agency Contract DSWA01-98-C-0176 The Mine The cooperating mine was the Morenci Mine operated by Phelps-Dodge in SE Arizona. The scale of the operation is illustrated below. The mine produces over 25% of all US copper. Three to five blasts are detonated daily. During July and August, 31% of the events in the USGS Mine Event List were from this mine. Regional...

We model the self-organization of the MinE ring that is observed during subcellular oscillations of the proteins MinD and MinE within the rod-shaped bacterium Escherichia coli. With a steady-state approximation, we can study the MinE ring generically--apart from the other details of the Min oscillation. Rebinding of MinE to depolymerizing MinD-filament tips controls MinE-ring formation through ...

In this paper we present a blender and eraser model that extends our graphite pencil and paper model. This blender and eraser model enhances the rendering results producing realistic looking graphite pencil tones and textures. Our model is based on observations on the absorptive and dispersive properties of blenders and erasers interacting with lead material deposited over drawing paper. The pa...

The vulnerability of water bodies to contamination within the neighbourhood of open mine cast environ cannot be overemphasized. Evidence of radioactive trace elements associated with the target minerals in the Plateau State (Nigeria) showed the extent of this vulnerability. In order to address this challenge, the radioactivity levels of water samples from mine ponds, streams, wells, and borehol...
