Inorganic modified green mudstone (MGM) was prepared from the (GM) residue of Fushun West Open Pit Mine and characterized by XRF, XRD, FTIR, SEM GM MGM. According to calculation pore size BET equation, specific surface area MGM were larger. The results adsorption kinetics isothermal experiments showed that capacity for phosphate increased 0.1 mg/g 0.71 mg/g, which obviously better than GM. acco...

Biorecovery of rare earth elements (REE) from wastes and ores is achieved by bacteria using biogenic phosphates. One approach uses an enzyme that biomineralises REE phosphate crystals into the extracellular polymeric matrix (EPM). The enzyme, co-localised in the EPM, provides a continuous phosphate feed into biomineralisation. The bacteria can be immobilised in a column, allowing continuous met...

Cogongrass {Imperata cylindrica) is a globally recognized invasive weed; it has caused land management problems and threatened critical habitat in the southeastern United States as well as on most continents. We tested four rates of imazapyr (1.17, 2.34, 3.51 and 4.68 L/ha), the most effective active ingredient available for cogongrass control, as two formulations (Chopper and the new generatio...

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 ...

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 ...

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...
