  • Occupational Safety and Health Training on the Internet Developing Quality Instruction
    Occupational Safety and Health Training on the Internet. Developing Quality Instruction
    Diether J ;
    Loos G
    2001/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    1. Training via the Internet (e-training) for adults must be based on the following principles: (1) learning is an active process wherein the learner constructs knowledge rather than acquires it and (2) instruction is a process of supporting this construction rather than communicating knowledge. E-training can successfully accommodate such features ...

  • The Mechanical and Histological Response of Rat Skeletal Muscle to Oscillatory Contractions In Vivo
    The Mechanical and Histological Response of Rat Skeletal Muscle to Oscillatory Contractions In Vivo
    Cutlip, Robert G. ;
    Geronilla KB
    2001/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    The aim of the present study was to examine skeletal muscle injury resulting from acute bouts of oscillatory contractions (strech-shortening contractions) in vivo. The injury is estimated by the changes in the mechanical and histological properties of the skeletal muscle before and after the exposures to oscillatory contractions. The dorsiflexor mu ...

    Relative Ventilation Effectiveness in a Mechanically Ventilated Airspace Under Isothermal Conditions
    Jerez SB ;
    Maghirang RG
    2001/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    The relative ventilation effectiveness for airborne dust was evaluated in a mechanically ventilated airspace under isothermal flow conditions. Three supply air inlets, specifically, one-way ceiling, two-way ceiling, and sidewall, were compared at ventilation rates of 0.1, 0.5, 0.7, and 1.0 m3/s. The dust concentrations were measured with inhalable ...

  • Particle and Gas Phase Interactions in Air Sampling
    Particle and Gas Phase Interactions in Air Sampling
    Soderholm, Sidney C.
    2001/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    An aerosol consists of airborne particles and sorrounding gases. The particle phase may include solids and liquids. The gas phase normally includes air and water vapor and may include vapors of organic and inorganic compounds as well as contaminant gases, such as sulfur dioxide. The distinction between a vapor and a gas is somewhat arbitrary. Follo ...

    Flint MS ;
    Tinkle SS
    2001/05/01 | National Institute for Occupational Safety and Health (NIOSH)
    C57BL/6 mice, in contrast to BALB/c mice, display minimal behavioral changes in response to environmental stressors and are considered relatively stress-resistant. We have shown that application of acute restraint prior to chemical challenge enhanced cutaneous hypersensitivity (CHS) in BALB/c mice and that this enhanced response is partially glucoc ...

    In order to increase farm safety awareness and teach children good safety habits, farm safety day camp programs have been initiated in many communities. For the most part, the effectiveness of the programs is unknown because few evaluations have been performed. The purpose of this project was to qualitatively assess the overall strengths and weakne ...
