  • Evaluating Vacant Middle Seats and Masks as Coronavirus Exposure Reduction Strategies in Aircraft Cabins Using Particle Tracer Experiments and Computational Fluid Dynamics Simulations
    Evaluating Vacant Middle Seats and Masks as Coronavirus Exposure Reduction Strategies in Aircraft Cabins Using Particle Tracer Experiments and Computational Fluid Dynamics Simulations
    Bennett JS ;
    Dietrich W
    2023/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    Aircraft cabins have high-performance ventilation systems, yet typically hold many persons in close proximity for long durations. The current study estimated airborne virus exposure and infection reductions when middle seats are vacant compared to full occupancy and when passengers wear surgical masks in aircraft. Tracer particle data reported by U ...

    2023/04/01 | Mining Publications
    Low-cost particulate matter (PM) sensors provide new methods for monitoring occupational exposure to hazardous substances, such as flour dust. These devices have many possible benefits, but much remains unknown about their performance for different exposure monitoring strategies in the workplace. We explored the performance of PM sensors for four d ...

  • Implications of Shale Gas Well Integrity Failure near a Longwall Mine Under Shallow Cover
    Implications of Shale Gas Well Integrity Failure near a Longwall Mine Under Shallow Cover
    Ajayi KM ;
    Khademian Z
    2023/04/01 | Mining Publications
    This study simulates the impact of a shale gas well casing breach near a longwall mine. Field studies are conducted to measure mining-induced permeability changes over the abutment pillar of a longwall mine, and a geomechanical model is developed in 3DEC, a three-dimensional numerical modeling code, to predict the aperture of fractures in the overb ...

    2023/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    Seals and build-in-place (BIP) refuge alternatives (RAs) are two main underground structures to isolate an area from the active working zones with different purposes. While seals are used to prevent methane gas that seeps from coal seams and blast pressures from a possible detonation of the contained gas, RAs are used to provide a safe haven for mi ...
  • Modified Design of Pillar Based on Estimated Stresses and Strength of Pillar in an Underground Limestone Mine
    Modified Design of Pillar Based on Estimated Stresses and Strength of Pillar in an Underground Limestone Mine

    2023/04/01 | National Institute for Occupational Safety and Health (NIOSH)
    The design and strength of pillars are important parameters while implementing the room-and-pillar mining method in a limestone mine. The process becomes complex with the presence of the karst voids which are frequent phenomena in a carbonate rock formation. The karst system is a network of cavities that along with an omnipresent fracture network m ...

    Understanding the challenges Law Enforcement Officers (LEOs) have encountered with their vehicle and equipment and the correlation between equipment configuration and LEO body dimensions is critical for improving vehicle/equipment specifications to better accommodate today's LEOs. 974 LEOs participated in a study on their vehicle, equipment, and bo ...

    The anterior and posterior iliac spine markers frequently used to define the pelvis, are commonly occluded during three-dimensional (3D) motion capture. The occlusion of these markers leads to the use of various tracking marker configurations on the pelvis, which affect kinematic results. The purpose of this investigation was to examine the agreeme ...

    Occupational exoskeletons have become more prevalent as an ergonomic control to reduce the physical demands of workers. While beneficial effects have been reported, there is relatively little evidence regarding potential adverse effects of exoskeletons on fall risk. The purpose of this study was to investigate the effects of a leg-support exoskelet ...

    The use of short message service (SMS) text messaging technology has grown in popularity over the last twenty years, but there is limited data on the design and feasibility of campaigns to reduce work-related injury, particularly among rural workers, non-native English speakers, and illiterate or low-literacy populations. Although there is a critic ...

    Background: Sleep and circadian disruption (SCD) is common and severe in the ICU. On the basis of rigorous evidence in non-ICU populations and emerging evidence in ICU populations, SCD is likely to have a profound negative impact on patient outcomes. Thus, it is urgent that we establish research priorities to advance understanding of ICU SCD. Metho ...
