    A System for Analyzing Aerosols Produced by Humans During Respiratory Maneuvers
    Afshari A ;
    Azadi S
    2001/10/01 | National Institute for Occupational Safety and Health (NIOSH)
    It has long been known that the spread of aerosols from person to person is one of the leading causes of respiratory disease. In order to characterize aerosols produced by humans, a system was constructed which measured the number and size of aerosols produced during voluntary coughs and forced exhalations (FE). The measurement system was enclosed ...

    Worksite tobacco control programs: the role of occupational health
    Sorensen, Glorian
    2001/10/01 | National Institute for Occupational Safety and Health (NIOSH)
    Worksite tobacco control initiatives face a crucial challenge: the growing occupational disparity in smoking prevalence. Blue-collar workers are more likely to be smokers than workers are in white-collar jobs. Blue-collar workers also experience a high prevalence of hazardous exposures on the job. Given these multiple risks, it is imperative that s ...

    2001/10/01 | National Institute for Occupational Safety and Health (NIOSH)
    A simple concise definition for surveillance is "data for action" (Giesecke, 1999). Surveillance data are vital for targeting public health resources. Traditionally, surveillance includes the ongoing collection, analysis, interpretation, and dissemination of data to prevent and control disease (Thacker and Berkelman, 1988). Surveillance data are us ...

    Little AR ;
    O'Callaghan JP
    2001/10/01 | National Institute for Occupational Safety and Health (NIOSH)
    Astrogliosis, characterized by the enhanced expression of GFAP, represents a remarkably homotypic response of astrocytes to all types of injuries of the CNS, including injuries of the developing CNS. As such, astrocytes serve as microsensors of the injured microenvironment regardless of their location in the CNS. The diversity of insults that engen ...

    Background: Workplace injuries and fatalities in the US create significant economic costs to society. Although economic costs should measure the opportunity cost to society arising from injuries and fatalities, estimating them often proves difficult as a practical matter. This leads to a range of estimates for valuing these costs. Methods: This pap ...
