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 Modern Woman: The Lost Sex Modern Woman: The Lost Sex is a 1947 work of scientific literature written by Ferdinand Lundberg and Marynia F. Farnham, M.D. which discusses the sociological and psychological context of American women in the post World War II era. Lundberg, a sociologist and social historian, and Farnham, a psychiatrist affiliated with the New York State Psychiatric Institute and Hospital, argue that "contemporary women in very large numbers are psychologically disordered and that their disorder is having terrible social and personal effects involving men in all departments of their lives as well as women."
