  • Quantification of Mechanical Behavior of Rat Tail Under Compression (Dataset)
    National Institute for Occupational Safety and Health
    2024/09/06 | National Institute for Occupational Safety and Health (NIOSH)
    The development of vibration-induced finger disorders is likely associated with combined static and dynamic responses of the fingers to vibration exposure. To study the mechanisms of these disorders, a new rat-tail model has been established to mimic the finger pressure and vibration exposures. However, the mechanical behavior of the tail during co ...

    Inhalation of welding fumes can cause metal accumulation in the brain, leading to Parkinsonian-like symptoms. Metal accumulation and altered neurochemical profiles have been observed using magnetic resonance imaging (MRI) in highly exposed welders, being associated with decreased motor function and cognition. While MRI is impractical to use as a he ...

    2024/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    Welding fumes are a Group 1 (carcinogenic to humans) carcinogen as classified by the International Agency for Research on Cancer. The process of welding creates inhalable fumes rich in iron (Fe) that may also contain known carcinogenic metals such as chromium (Cr) and nickel (Ni). Epidemiological evidence has shown that both mild steel (Fe-rich) an ...

    2024/09/01 | National Institute for Occupational Safety and Health (NIOSH)
    The amount of time available in a day is fixed, and consequently, sleep is often sacrificed for waking activities. For college students, daily activities, comprised of scheduled classes, work, study, social, and other extracurricular events, are major contributors to insufficient and poor-quality sleep. We investigated the impact of daily schedules ...
