The generation and migration of bedforms (eg, ripples, megaripples and sand bars) on sandy bottoms in the nearshore (0-8 m water depths) provides a mechanism for objects on the seafloor to become buried. As a bedform migrates past a mine, the mine will fall to the low point of the bedform trough before subsequently being buried by the passage of the following bedform crest. The statistics of mi...

A novel chromogenic medium, Spectra MRSA (Remel, Lenexa, KS), was designed to detect methicillin-resistant Staphylococcus aureus (MRSA) rapidly and more efficiently than traditional media (i.e., tryptic soy agar with 5% sheep blood [SBA] and mannitol salt agar [MSA]). A multicenter study (including four clinical trial sites and the Medical College of Wisconsin [MCW] Milwaukee, WI) compared the ...

Based on the data of geological drill holes, roadway drifting, transient electromagnetic exploration, mine water inrushes, hydro-geochemistry and water levels on each side of the Haotang Normal Fault, this paper studies the waterbearing capacity and water conductivity of the fault in the Pingdingshan Tian’an Mining Company Limited No. 7 Coal Mine. The results indicate that the Haotang Fault is ...

Abstract: The mine dust deposited on sanded surfaces of test samples in the acrylic bonding exercise of March, 1992 was found by x-ray fluorescence analysis to be 0.05 (+0.07, -0.05) ng/cm2. This is well below the level at which mine dust in bonded joints would present a problem for SNO. The efficiency of the adhesive tape used in the XRF analysis for the removal of mine dust from a sanded surf...

Using data on work accidents and annual mining statistics, the paper studies work-related accidents in the Spanish energetic mining sector in 1999-2008. The following 3 parameters are considered: age, experience and size of the mine (in number of workers) where the accident took place. The main objective of this paper is to show the relationship between different accident indicators: risk index...

Interferometric Synthetic Aperture Radar observations of surface deformation due to the 1999 Hector Mine earthquake reveal motion on several nearby faults of the eastern California shear zone. We document both vertical and horizontal displacements of several millimeters to several centimeters across kilometer-wide zones centered on pre-existing faults. Portions of some faults experienced retrog...

Total Hg and methyl-Hg were evaluated in mine wastes, soils, water, and vegetations from the Wuchuan Hg-mining areas, Guizhou, China. Mine wastes contain high total Hg concentrations, ranging from 79 to 710 microg g(-1), and methyl-Hg from 0.32 to 3.9 ng g(-1). Total Hg in soil samples range from 0.33 to 320 microg g(-1) and methyl-Hg from 0.69 to 20 ng g(-1). Vegetations present a high average...

When a key press causes a stimulus, the key press is perceived later and the stimulus earlier than key presses and stimuli presented independently. This bias in time perception has been linked to the intention to produce the effect and thus been called intentional binding (IB). In recent studies it has been shown that the IB effect is stronger when participants believed that they caused the eff...

Peter Singer, in his essay "Utilitarianism and Vegetarianism" (Philosoohv and Public Affairs, vol. 9, no. 4, pp. 325-37),1 has gone some distance toward clarifying his view of the utilitarian case for the ob­ ligation to be vegetarian. The fact that this clearer statement of his position was prompted, at least in part, by an essay of mine ("Utilitarianism, Vegetarianism, and Animal Rights," Phi...

fied as a factor in the spread of HIV throughout southern Africa. Today, migrant workers remain a key population to target for HIV prevention efforts not only because of their role in its transmission, but also because of their own vulnerability to the disease as a result of high-risk sexual behavior.1 In South Africa, mine workers comprise a large number of the migrant workers who fall into th...
