Work of breathing When there is increased gas flow resistance, the optimal respiratory rate decreases. This work (generally during the inhalation phase) is stored as potential energy which is recovered during exhalation. A pressure difference is required to overcome the frictional resistance to gas flow due to viscosity, and to provide non-elastic components of movement of the airway tissues to accommodate pulmonary volume change. Total work done against non elastic forces is 35% of total. Work is defined as a force applied over a distance. The SI unit of work is the Joule, equivalent to a force of 1 Newton exerted along a
Modern Woman: The Lost Sex work referred to when discussion women's roles in American culture, by both men and women. Women even used Lundberg and Farnham's book as a self-help text in advice columns in large newspapers. One advice columnist consistently referred readers to "Modern Woman: The Lost Sex" in "The Washington Post." The book also appeared on the American Library Association's 'Fifty Notable Books of 1947' list as well as the Society for Science and the Public's 'Books of the Week' list in April 1947.
