  • How Gas Trapping at Low Lung Volumes Affect Energy Required to Expand Lung to Total Lung Capacity
    How Gas Trapping at Low Lung Volumes Affect Energy Required to Expand Lung to Total Lung Capacity?
    Frazer D ;
    Friend KA
    2001/10/04 | National Institute for Occupational Safety and Health (NIOSH)
    When an excised lung is slowly ventilated, not all gas entering the lung during inflation can be removed during the following lung deflation. In order to develop a realistic model of the gas trapping process, it is important to determine the mechanical characteristics of the region of the lung where gas trapping takes place. In this study, excised ...

    2001/10/01 | National Institute for Occupational Safety and Health (NIOSH)
    Many assembly line balancing algorithms consider only task precedence and duration when minimizing cycle time. However, disregarding the physical demands of these tasks may contribute to the development of work-related musculoskeletal disorders in the assembly line workers. Three line balancing heuristics that incorporate physical demand criteria w ...
