Abstract

A self-consistent global model of solenoidal-type inductively coupled plasma discharges including the effects of radio-frequency bias power

Short-term exercise training improves aerobic capacity with no change in arterial function in obesity

“…Improvement in endothelialdependent dilation in porcine conduit arteries following 7-10 days of aerobic exercise training have been reported (Johnson et al 2001;Laughlin et al 2003;McAllister and Laughlin 1997), and similar Wndings were observed in canine models using coronary arteries (Sessa et al 1994;Wang et al 1993). Although we hypothesized that shortterm training would improve FMD, the exercise protocol employed in the present study did not enhance FMD despite the resultant positive metabolic changes.…”

Experimental Observation and Computational Analysis of Striations in Electronegative Capacitively Coupled Radio-Frequency Plasmas

“…These "striations" are found to be generated by the resonance between the driving radio-frequency and the eigenfrequency of the ion-ion plasma (derived from an analytical model) that establishes a modulation of the electric field, the ion densities, as well as the energy gain and loss processes of electrons in the plasma. The growth of the instability is followed by the numerical simulations.Plasmas in electronegative gases exhibit complex physical and chemical kinetics [1][2][3][4][5][6][7][8][9][10][11]. Their main constituents are typically positive and negative ions, and electrons are only present as a minor species.…”

Fundamentals and applications of ion–ion plasmas

“…A one-dimensional fluid model of an ion-ion plasma (with no residual electrons) was developed which resolved the sheath regions near the walls. The model included the Poisson equation for the electrostatic field coupled with the continuity and momentum equations of the ion density and velocity [22].…”

“…For example, in ion-ion plasmas, the plasma potential does not have to be the most positive potential in the system (as in electron-ion plasmas). In fact, the potential profile across an ion-ion plasma can be monotonically decreasing from one electrode to the other [22], much like in liquid electrolytes [23].…”
