  • Transfer Function Analysis of Respiration of Laboratory Animals
    Transfer Function Analysis of Respiration of Laboratory Animals
    Frazer D ;
    Friend K
    2000/10/12 | National Institute for Occupational Safety and Health (NIOSH)
    A transfer function analysis technique was developed to measure the resistance-compliance time constant (RC) of the lungs of laboratory animals. The change in volume of the thorax with respect to time (thoracic flow) was taken as the system input, and the flow from the nares was taken as the output. Fourier analysis was used to calculate the transf ...

  • Examining Longwall Shield Failures from an Engineering Design and Operational Perspective
    Examining Longwall Shield Failures from an Engineering Design and Operational Perspective
    Barczak, Thomas M.
    2000/10/01 | Mining Publications
    Longwall operators are again pushing the envelope in terms of life expectancy for longwall shields. State-of-the-art shields are now expected to last more than 60,000 loading cycles, twice the life expectancy compared with those of a decade ago. A review of trends in shield design shows that shields continue to increase in both size and capacity. S ...

    Dolinar, Dennis R. ;
    Martin, Lewis A.
    2000/10/01 | Mining Publications
    Cable bolt technology used by the U.S. coal industry was developed to a large extent in the 1990s. Today, these cable systems include both cable bolts and cable trusses to provide supplemental and secondary support in gate roads. This cable technology is significantly different than the cable systems in use in either U.S. hardrock mines or Australi ...

    2000/10/01 | National Institute for Occupational Safety and Health (NIOSH)
    Silicosis is a deadly lung disease. Construction workers may get sick with silicosis if they breathe in too much respirable crystalline silica, a fine, sandy dust. Silicosis may take 10 or more years to develop when workers are exposed daily to low concentrations of silica dust. However, when exposures to silica are very high, symptoms can occur af ...
