Computational investigations of atmospheric pressure discharges
… variables in the uniform and filamentary discharges. The homogeneous uniform slice distributions of electrons density are compared at different frequencies, which show the trapping of electrons in the positive column at higher frequencies. The non-uniform distribution of axial electric …

Nanosecond pulse discharges in electronegative gases
… C^Fg-Ar mixtures in self and non-self sustained discharges is discussed. Another experiment was conducted in a 30-70% C^Fg-Ar mixture at 1480 Torr to observe the difference in current development for single and multiple electron initiated discharges. When the initial number of electrons is large …

Ignition by Nanosecond Repetitively Pulsed Discharges
… triggered by Nanosecond Repetitively Pulsed discharges (NRP). The models developed are used to explore the influence of various parameters in an optimization effort. Using the 0D model, the influence of initial gas temperature and energy deposited per pulse on the reduction of ignition delay …

Local marine wastewater discharges : characterisation and impacts
Raw municipal wastewaters from the three major sewage pumping stations in the Maltese Islands were sampled three times daily over a 7-day period in August-September 2002 so as to identify levels of suspended matter, nutrients (nitrates, nitrites, orthophosphates and total phosphorus), and …

Experimental investigation of CO2 valorization by plasma discharges
… Non-thermal plasmas generated by electrical discharges in gases are among the promising techniques for tackling this challenge. The non-equilibrium properties of plasmas can be exploited to channel energy in the molecular dissociation rather than in heating the gas, allowing endothermic …

Propagation of generalised discharges in idiopathic generalised epilepsy
… generalised epilepsy (IGE) show generalised discharges, which are assumed to occur synchronously over the entire cortex. We hypothesis that (1) Generalised discharges are propagated and this can be shown by latency differences between EEG spikes recorded over homologous sites at discharge …

Predicting surgical inpatients' discharges at Massachusetts General Hospital
… mismatch between the timing of admissions and discharges. Particularly, while bed managers know about most admissions well in advance, there is a prevalent lack of central transparency regarding which patients might be ready to leave the hospital and what are the barriers that may delay their …

Predicting medicine inpatient discharges at Massachusetts General Hospital
… occur throughout the day, and the timing of discharges, which typically occur in the afternoon. Furthermore, although bed managers know about scheduled admissions in advance, there is no standardized protocol that allows bed managers at the Admitting Department to identify which patients are …

Design of Optical Measurements for Electrothermal Plasma Discharges
Ablation controlled electrothermal (ET) plasma discharge devices consist of a small diameter capillary through which a large amount of energy is discharged. The high energy in the discharge ablates an inner sleeve material, ionizes the material, and a high energy-density plasma jet accelerates out …

Two-dimensional, Hydrodynamic Modeling of Electrothermal Plasma Discharges
… developed to model electrothermal (ET) plasma discharges. ET plasma discharges are capillary discharges that draw tens of kA of electric current. The current heats the plasma, and the plasma radiates energy to the capillary walls. The capillary walls ablate by melting and vaporizing and by …

Mapping Groundwater Discharges to Rivers near Oil Sands Projects
Groundwater discharges in the western Canadian oil sands region impact river water quality. Mapping groundwater discharges into rivers in the oil sands region is important to ensure wastewater and steam injections remain sequestered, rather than eventually resurfacing. Saline springs comprised of …

Delayed discharges from an adult intensive care unit (ICU)
… units is imperative. The occurrence of delayed discharges and the reason for the delays is important as they impact on the efficiency and effectiveness of intensive care unit services. Patients who no longer need intensive care unit care block beds for impending admissions, unnecessarily utilise …

Characterization of Microwave Cavity Discharges in a Supersonic Flow
… Detailed characterization of supersonic flowing discharges is important to many applications in aerospace and aerodynamics. One application is the use of plasma-assisted hydrogen combustion devices to aid in supersonic combustion. In conditions close to the real combustion environment, a …
