Two seams at the Tab-Simco abandoned underground coal mine site in southern Illinois were mined intermittently from the 1890’s until 1955, and later surface mined. The stripping operations resulted in several break-ins into the old underground works which were later buried by mine spoil. The resulting mine pool in the lower of the two seams has been producing an average of ~150 m per day of aci...

This study investigated dispersion and bioaccumulation of mining-related elements from an open-pit olivine mine at Seqi in Southwest Greenland (64° N) using lichens (Flavocetraria nivalis), seaweeds (Fucus vesiculosus), mussels (Mytilus edulis) and fish (Myoxocephalus scorpius). The mine operated between 2005 and 2009, and samples were taken every year within a monitoring area 0-17 km from the ...

We propose a simple generalization of the Brennan-Schwartz approach to real option valuation of a mining project that incorporates disaster risk using a Poisson point process to model arrivals. Using techniques from the field of robust performance analysis, we are able to calculate upper and lower bounds over all the probability models within a certain distance from the original model. We sugge...

Hodnotenie nebezpečnosti banských plynov v uzavretej čiernouhoľnej bani „Niwka-Modrzejów” Closing of hard coal mines, especially stopping the process of mine water pumping, results in a reconstruction of the Carboniferous water-bearing horizon, leading to the intensification of gas flux to the near-surface zone („piston effect”). Stopping the fans considerably enhances the movement of mine gase...

We demonstrate a three stage procedure for mine detection. The rst phase locates plausible candidates through a series of hypothesis tests. The second state nds the globally optimal convex set containing each candidate using \coarse-tone" dynamic programming. The third stage re nes the mine shape estimates using the knowledge contained in a mine-shape library.

Escherichia coli cells contain potential division sites at midcell and adjacent to the cell poles. Selection of the correct division site at midcell is controlled by three proteins: MinC, MinD, and MinE. It has previously been shown (D. Raskin and P. de Boer, Cell 91:685-694, 1997) that MinE-Gfp localizes to the midcell site in an MinD-dependent manner. We use here Gfp-MinD to show that MinD as...

Pole-to-pole oscillations of the Min proteins in Escherichia coli are required for the proper placement of the division septum. Direct interaction of MinE with the cell membrane is critical for the dynamic behavior of the Min system. In vitro, this MinE-membrane interaction led to membrane deformation; however, the underlying mechanism remained unclear. Here we report that MinE-induced membrane...

In western United States, both mine reclamations and renewed mining at previously abandoned mines have increased substantially in the last decade. This increased activity may adversely impact bats that use these mines for roosting. Townsend’s big-eared bat (Corynorhinus townsendii) is a species of conservation concern that may be impacted by ongoing mine reclamation and renewedmineral extractio...

The German Rhineland is home to the world's largest opencast lignite coal mine and human-made hole e the Hambach mine. Over the last seven years, RWE, the mine operator, has faced an increase in militant resistance, culminating in the occupation of the Hambacher Forest and acts of civil disobedience and sabotage. The mine provides a European case study to examine the repressive techniques deplo...

BACKGROUND The use of formative research as a critical component of intervention planning is highly supported in the literature. However, studies that report such processes in practice are minimal. This paper reports on the formative data collection and analysis that informed the development of a multilevel intervention that utilizes mine assessment technology to bridge health communication bet...
