    Individuals with specific phase I and phase II enzyme polymorphisms may be at increased risk for squamous cell carcinoma of the esophagus. However, to our knowledge there has been only one previous report that evaluates a potential role for these polymorphisms in increasing risk for preneoplastic squamous lesions of the esophagus. To explore this f ...

    2000/08/01 | Mining Publications
    Prolonged exposure to noise over a period of years generally causes permanent damage to the auditory nerve and/or its sensory components. This irreversible damage, known as noise-induced hearing loss (NIHL), is th most common occupational disease in the United States today. Workers suffering from NIHL have difficulty understanding human speech and ...

    Needlestick injuries can expose workers to a number of bloodborne pathogens that can cause serious or fatal infections. The pathogens that pose the most serious health risks are: hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) -- the virus that causes AIDS. HBV vaccination is recommended for all health care ...

    2000/08/01 | Mining Publications
    Point load testing is used to determine rock strength indexes in geotechnical practice. The point load test apparatus and procedure enables economical testing of core or lump rock samples in either a field or laboratory setting. In order to estimate uniaxial compressive strength, index-to-strength conversion factors are used. These factors have bee ...

    Safety has been recognized officially as an important concern for over 100 years. The Railway Safety Act was enacted in the US in 1893. In 1908, U.S. Steel began a corporate safety program (Hammer, 1989). In order to satisfy the safety needs of both the industrial worker and the public, researchers have evaluated and investigated the principles of ...

    2000/07/30 | National Institute for Occupational Safety and Health (NIOSH)
    This paper proposes a new method to identify slip distance and adjusted required coefficient friction to predict falls among different age groups. These methods were based on the fact that the dynamics of slips are altered due to the fall arresting rig (or harness) during the critical moment of slips and falls. [Description provided by NIOSH]
