An ion species model for positive ion sources - part I description of the model [PDF]

Plasma Sources Science and Technology, Vol.24, No.1, February 2015, pp.015035, 2014
A one dimensional model of the magnetic multipole volume plasma source has been developed for use in intense ion/neutral atom beam injectors. The model uses plasma transport coefficients for particle and energy flow to create a detailed description of the plasma parameters along an axis parallel to that of the extracted beam.

Relativistic Nonlinear Whistler Waves in Cold Magnetized Plasmas [PDF]

2019 Plasma Res. Express 1 015005, 2018
Starting from the Vlasov-Maxwell equations describing the dynamics of various species in a quasi-neutral plasma immersed in an external solenoidal magnetic field and utilizing a technique known as the hydrodynamic substitution, a relativistic hydrodynamic system of equations governing the dynamics of various species has been obtained.

Computer-guided concentration-controlled trials in autoimmune disorders [PDF]

, 1993
A randomized concentration-controlled clinical trial (RCCCT) is an alternate experimental design to the standard dose-controlled study. In a RCCCT, patients are randomly assigned to predefined plasma or blood drug concentration ranges (low, medium, and ...

Evaluating the efficacy of a standardized 4 mL/kg fluid bolus technique in critically ill patients with elevated PvaCO2: secondary analysis of two prospective studies

Frontiers in Medicine
BackgroundLimiting the fluid bolus (FB) volume may attenuate side effects, including hemodilution and increased filling pressures, but it may also reduce hemodynamic responsiveness.

The dual effects of Al-doping on the ferromagnetism of Zn0.98–yEr0.02AlyO thin films

AIP Advances, 2013
Zn0.98–yEr0.02AlyO (0 ≤ y ≤ 0.04) thin films have been prepared by inductively coupled plasma enhanced physical vapor deposition method. It is found that Er3+ substitutes Zn2+ in ZnO lattice without forming any magnetic secondary phase.

Alfvén wave phase-mixing in flows: Why over-dense, solar coronal, open magnetic field structures are cool? [PDF]

A&A 586, A95 (2016), 2015
The motivation for this study is to include the effect of plasma flow in Alfv\'en wave (AW) damping via phase mixing and to explore the observational implications. Our magnetohydrodynamic (MHD) simulations and analytical calculations show that, when a background flow is present, mathematical expressions for the AW damping via phase mixing are modified ...
