  • IoTEnabled Wearable FatigueTracking System for Mine Operators
    IoT-Enabled Wearable Fatigue-Tracking System for Mine Operators
    Drews FA ;
    Marques J
    2023/02/18 | National Institute for Occupational Safety and Health (NIOSH)
    This study explores the possibility of investigating operator fatigue via the use of off-the-shelf wearable devices and custom applications. Fatigue is a complex biological phenomenon, and both subjective and objective data are needed to assess it properly. The development of any application and the assessments of fatigue should be guided by psycho ...
  • A Markov Chain Model for Mental Health Interventions
    A Markov Chain Model for Mental Health Interventions
    Albano T ;
    Claudio D
    2023/02/16 | National Institute for Occupational Safety and Health (NIOSH)
    Poor mental health affects nearly one billion people worldwide and can end in suicide if not treated. Unfortunately, stigma and a lack of mental healthcare providers are barriers to receiving needed care. We developed a Markov chain model to determine whether decreasing stigma or increasing available resources improves mental health outcomes. We ma ...

    2023/02/16 | National Institute for Occupational Safety and Health (NIOSH)
    Dietary long-chain omega-3 polyunsaturated fatty acids (n-3 PUFA) and their pro-resolving metabolites are protective against atherosclerotic disease, and ameliorate systemic inflammatory conditions including lupus erythematosus, psoriasis, and bronchial asthma. Organic bioaerosol inhalation is a common and injurious hazard associated with agricultu ...

    Farooqi, Muhammad S. ;
    Grunig, Gabriele
    2023/02/15 | National Institute for Occupational Safety and Health (NIOSH)
    Background: Particulate matter (PM) exposure is responsible for seven million deaths annually and has been implicated in the pathogenesis of respiratory infections such as severe acute respiratory syndrome (SARS). Understanding modifiable risk factors of high mortality, resource burdensome C19 and exposure risks such as PM is key to mitigating thei ...

    Analysis and Validation of Sensitivity in Torque-Sensitive Actuators
    Gabert L ;
    Lenzi T
    2023/02/14 | National Institute for Occupational Safety and Health (NIOSH)
    Across different fields within robotics, there is a great need for lightweight, efficient actuators with human-like performance. Linkage-based passive variable transmissions and torque-sensitive transmissions have emerged as promising solutions to meet this need by significantly increasing actuator efficiency and power density, but their modeling a ...
  • Correlation Between Graphitic Carbon and Elemental Carbon in Diesel Particulate Matter in Workplace Atmospheres
    Correlation Between Graphitic Carbon and Elemental Carbon in Diesel Particulate Matter in Workplace Atmospheres
    Birch, M. Eileen ;
    Breitenstein, Michael J.
    2023/02/14 | National Institute for Occupational Safety and Health (NIOSH)
    We investigated the suitability of the graphitic carbon (GC) content of diesel particulate matter (DPM), measured using Raman spectroscopy, as a surrogate measure of elemental carbon (EC) determined by thermal optical analysis. The Raman spectra in the range of 800-1800 cm-1 (including the D mode at approx. 1322 cm-1 and the G mode at approx. 1595 ...

  • Associations of WorkRelated Injuries and Stress to Family and Youth Wellbeing Among US Latinoa Immigrant Cattle Feedyard Workers
    Associations of Work-Related Injuries and Stress to Family and Youth Wellbeing Among U.S. Latino/a Immigrant Cattle Feedyard Workers
    Carlo G ;
    Maiya S
    2023/02/14 | National Institute for Occupational Safety and Health (NIOSH)
    Based on the Ecological Stress-Based Model of Immigrant Worker Safety and Health, we hypothesized that occupational stress and physical safety would be negatively linked to workers' depression, which in turn, would increase family conflict and decrease youth prosocial behaviors. A total of 242 Latino immigrant cattle feedyard workers from Nebraska ...
