  • Longwall Tailgate SupportConsideration Design and Experience
    Longwall Tailgate Support-Consideration, Design and Experience
    Barczak, Thomas M. ;
    Bower J
    1999/09/21 | Mining Publications
    Maintaining ground stability in the gate roads, particularly the tailgate, has always been critical to the success of longwall mining, both in terms of safety and productivity. Several new support technologies have been developed in recent years to replace conventional wood and concrete cribbing for secondary roof support. While the primary goal co ...

  • Regulation of a Cell TypeSpecific Silencer in the Human iInterleukin3 Gene Promoter by the Transcription Factor YY1 and an AP2 SequenceRecognizing Factor
    Regulation of a Cell Type-Specific Silencer in the Human iInterleukin-3 Gene Promoter by the Transcription Factor YY1 and an AP2 Sequence-Recognizing Factor
    Castranova, Vincent ;
    Shi X
    1999/09/17 | National Institute for Occupational Safety and Health (NIOSH)
    Negative regulation of cytokine gene transcription is an important mechanism in maintaining homeostasis of immune function. In this study, we characterized a silencer element in the human interleukin-3 gene promoter that is responsible for the cell-specific expression of interleukin-3. This silencer activity was proposed to be mediated by an uniden ...

    1999/09/15 | National Institute for Occupational Safety and Health (NIOSH)
    In the past, the relationship between pulmonary hysteresis and a model of the recruitment-derecruitment of lung units has been explored (Cheng, W., DeLong, D.S., Franz, G.N., Petsonk, E.L., Frazer, D.G., 1995, Resp. Physiol. 102, 205-215). The recruitment process is characterized by a sequence of events which represents discrete configurational cha ...

    1999/09/05 | National Institute for Occupational Safety and Health (NIOSH)
    Cysteinyl adducts of hemoglobin (Hb) and albumin (Alb) formed via reactions with reactive species were measured in 48 subjects exposed to styrene (0.24-55.2 ppm) and to styrene-7,8-oxide (SO) (2.65-107 ppb) in a factory producing boats in the USA. Hb and Alb adducts were also investigated among 88 workers exposed to benzene (0-138 ppm) in several C ...

    Hand exposures of apple thinners to the pesticide azinphos-methyl (Guthion) were measured using three methods (glove, handwash, and wipe). Hand exposure sampling for each method was conducted following apple thinning work for a period of two hours for six to eight workers. Foliar residue samples were collected on each day of hand exposure sampling ...

    Young agricultural production workers have a three-fold greater risk of death than private sector workers nationally. The male/female gender composition of fatalities among young agricultural production workers is similar to other studies of adults (Myers and Hard, 1995). Farm tractors were the leading source of fatalities for young agricultural wo ...

    The exposure estimates used to date for the analysis of lung cancer mortality in the Colorado Plateau Uranium Miners cohort were developed from radon progeny measurements taken in mines beginning in 1951. Since uranium miners were often exposed over long periods of time and since mines were not continuously monitored, much extrapolation and/or inte ...
