Spontaneous branching of discharge channels is frequently observed, but not well understood. We recently proposed a new branching mechanism based on simulations of a simple continuous discharge model in high fields. We here present analytical results for such streamers in the Lozansky-Firsov limit where they can be modeled as moving equipotential ionization fronts. This model can be analyzed by...

Spontaneous loss of charge by charged black holes by means of pair-creation of charged Dirac particles is considered. We provide three examples of exact calculations for the spontaneous discharge process for 4D charged black holes by considering the process on three special nonrotating de Sitter black hole backgrounds, which allow to bring back the problem to a Kaluza-Klein reduction. Both the ...

The effects of ionic change upon one of the two classes of aortic baroreceptors, those having unmyelinated axons or C-fibers, have not been examined heretofore. Differences from results in aortic baroreceptors with myelinated axons might be expected because of differences in accessible surface area-volume relationships. Recordings were obtained using an in vitro aortic arch-aortic nerve prepara...

PURPOSE To evaluate the impact of a redesigned intensive care unit (ICU) nursing discharge process on ICU discharge delay, hospital mortality, and ICU readmission within 72 hours. METHODS A quality improvement study using a time series design and statistical process control analysis was conducted in one Australian general ICU. The primary outcome measure was hours of discharge delay per patie...

The aim of this study was to investigate the effects of agmatine (Agm) on the electrical activity of neurons in subfornical organ (SFO) slices using extracellular recording technique. The results are as follows. (1) In response to the application of Agm (1.0 micromol/L) into the superfusate for 2 min, the discharge rate of 24/28 (85.7%) subfornical neurons was decreased significantly, while the...

Sagreiya, K., and Emery, J. L. (1970). Archives of Disease in Childhood, 45, 746. Perinatal thyroid discharge: a histological study of 1225 infant thyroids. A random sample of 500 infant thyroids in which post-mortem changes were, as far as possible, eliminated was studied histologically. In the great majority ofneonatal thyroids there are distinct changes which suggest the occurrence of an acu...

Experiments were conducted to evaluate the influence of sediment concentration, slope and discharge on sediment deposition rates and patterns associated with a reduction in bed slope. Analysis of the data shows that up to a certain unit discharge a simple settling equation without a transport term gives a good prediction of the sediment delivery ratio and the grain-size distribution of the depo...

Faecal coliform (FC) concentration was monitored weekly in the Tangipahoa River over an eight year period. Available USGS discharge and precipitation data were used to construct a nonparametric multiplicative regression (NPMR) model for both forecasting and backcasting of FC density. NPMR backcasting and forecasting of FC allowed for estimation of concentration for any flow regime. During this ...
