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
Work unit Communist Party infrastructure. Work units were the principal method of implementing party policy. Also workers were bound to their work unit for life. Each "danwei" created their own housing, child care, schools, clinics, shops, services, post offices, etc. The unit concept used in developing the work unit comes from Hegelian and especially behaviorist social science. Other related examples include the neighbourhood unit in developments, study of living creatures at the level of a defined ecological unit, the entity concept from accounting, the strategic business unit in commerce, the unit concept of church fellowship in the Wisconsin Evangelical Lutheran Synod, the
