    During this SBIR Phase I project, Nanomaterials Research (NRLLC) successfully demonstrated a new type of sensor device for detecting hydrogen sulfide (H2S). This gas is extremely toxic at low concentrations, and workplace exposure is common in a number of industries. Improved sensors and gas detection instruments are sorely needed to ensure protect ...

    Effect of the Streptococcus pneumoniae MmsA protein on the RecA protein-promoted three-strand exchange reaction. Implications for the mechanism of transformational recombination
    Bryant FR ;
    Hedayati MA
    2002/07/12 | National Institute for Occupational Safety and Health (NIOSH)
    Streptococcus pneumoniae is a naturally transformable bacterium that is able to incorporate DNA from its environment into its own chromosome. This process, known as transformational recombination, is dependent in part on the mmsA gene, which encodes a protein having a sequence that is 40% identical to that of the Escherichia coli RecG protein, a ju ...

    2002/07/12 | National Institute for Occupational Safety and Health (NIOSH)
    A physiologically based pharmacokinetic (PBPK) model to describe the absorption, distribution, metabolism, and elimination of methyl ethyl ketone (MEK) in rats was developed. Partition coefficients were experimentally determined in rat tissues and blood samples using an in vitro vial equilibration technique. These solubility ratios were in agreemen ...

    Whyatt, Jeffrey K.
    2002/07/10 | Mining Publications
    Detailed mapping and examination of the site of a large rock burst at the Lucky Friday Mine, Mullan, ID, demonstrated conclusively that damage was caused by a splitting and buckling failure mechanism initiated by separation of rock into layers along steeply dipping metamorphic shear foliation subparallel to the affected crosscut. The thin tablular ...

  • Roof Wedge Stability A Simple Analytical Model and Numerical Validation Using Deformable Blocks
    Roof Wedge Stability: A Simple Analytical Model and Numerical Validation Using Deformable Blocks
    MacLaughlin, Mary M.
    2002/07/10 | Mining Publications
    Wedge-shaped roof falls are an extremely common mode of failure of underground openings in jointed rock. Although a number of sophisticated analytical solutions have been developed to determine the stability of roof wedges, a simple approach may also be used to provide an estimate of wedge stability. The simple two-dimensional model assumes the wed ...

    2002/07/10 | Mining Publications
    The study of neutrinos-particles infinitesimally smaller than atoms-would be significantly advanced if a deep underground facility were available that would filter out unwanted cosmic radiation. Encouraging progress has been made in satisfying the criteria for such a facility with the selection of the Homestake Mine in Lead, SD, by the National Und ...

    The practice in thick seam longwall mining at depths of 500 m and more shows that considerable sloughing of chain pillars, sometimes accompanied by bumps, may occur during development stage. The ability of these pillars to continue functioning as roof support during development and long walling stages has to be assured for a safe and economical min ...

    2002/07/10 | Mining Publications
    Many industries store and handle solid materials in bulk form. When the volume of the solids is large, industry invariably relies upon the gravity to induce the solids to flow out of storage, through channels and reactors. As an example production in most deep underground mines depends on the safe and continuous operation of ore pass systems. Their ...

    In guinea-pig perfused trachea preparations, application of methacholine (MCh) to the serosal surface elicits contraction of the airway smooth' muscle. Increasing the tonicity of the modified Krebs-Henseleit solution (MKHS) bathing the epithelium with D-mannitol (D-M) causes an epithelium-dependent relaxation. In this study, we compared bioelectric ...
