Bøker av David W. Johnson

David Johnson examines the Christian spiritual life using the Book of Confessions of the Presbyterian Church (U.S.A.) as a guide.

Carter and Ralph Stanley - the Stanley Brothers - are comparable to Bill Monroe and Flatt & Scruggs as important members of the earliest generation of bluegrass musicians. In this first biography of the brothers, author David W. Johnson documents that Carter (1925-1966) and Ralph (b 1927) were equally important contributors to the tradition of old-time country music.

This book documents CCPS's Aerosol Research Program to develop a model to predict liquid rainout from release of a pressurized, liquefied gas--and, hence the residual amount of material in a vapor cloud, which may be greater than the amount calculated from an enthalpy chart. RELEASE predicts the rate of fluid discharge, the depressurization, flashing and formation of liquid drops, the entrainment of drops into the vapor cloud, the subsequent spreading of the jet, and rate of liquid rainout to a pool on the ground. Designed in a modular fashion to permit adjustment and corrections as new data become available, its multi-layered approach contains sub-models that include the complexities of many variables, including the effect of liquid superheat, rate of bubble growth, criterion for bubble formation, and heat transfer from the liquid to the growing vapor bubble. To validate RELEASE, CCPS conducted small- and large-scale experiments using superheated water, heated liquefied chlorine, methylamine, and cyclohexane that produced valuable data in an area where data are scarce. This book gives complete access, in text and on CD-ROM, to the model and the test data, giving users an informed ability to apply the model to their own work.
