Recent experiments on DIII-D have focused on elucidating the drive mechanisms for intrinsic rotation in tokamak fusion plasmas. For a wide range of DIII-D H-mode plasmas, the effective torque at the edge ( >0.8) associated with the intrinsic rotation shows a dependence on the edge pressure gradient, which is qualitatively consistent with models describing E B shear as a means of creating “resid...

Examples of the use of Frenet curvature-driven motion of vortex unstretched filamentary diffusion processes in plasmas are investigated. The first example addresses the unstretched filaments which are embedded in a steady plasma flow. The particle number density of a weakly ionized plasma is shown to be proportional to the total Frenet curvature. The particle number does not decays in plasma al...

In magnetized plasmas gravitational and electromagnetic waves may interact coherently and exchange energy between themselves and with plasma flows. We derive the wave interaction equations for these processes in the case of waves propagating perpendicular respectively parallel with the plasma background magnetic field. In the latter case, the electromagnetic waves are taken to be circularly pol...

An alternative experimental spectroscopic measurement of poloidal plasma rotation in toroidally confined plasmas is proven effective in the TCV tokamak. Charge exchange recombination measurements of the toroidal rotation profile over the full mid-plane plasma diameter are used to infer the complete bi-dimensional flow structure of the intrinsic C6+ impurity, which includes its poloidal componen...

a simple, rapid and sensitive high-performance liquid chromatographic (hplc) method for the determination of risperidone in human plasma was developed. an hplc system based on a nucleosil c8 column (150?4 mm) and a uv detector (?= 280 nm) were used. a mixture of sodium dihydrogen phosphate buffer-acetonitrile (55:45, v/v) adjusted to ph 6.0 at a flow rate of 1.5 ml min-1 was used as mobile phas...

Abstract This article reviews and discusses the recent progresses of studies with concept “Computational plasma fluid mechanics.” Computational demonstrations show that inhouse simulation codes such as PLasma All-Speed Turbulence Implicit Pressure Code have captured hydrodynamic instabilities reproduced flow dynamics in thermal plasma—nonionized gas coexisting systems. A unique method has made ...

Our aim was to study the effect of an axially directed blood plasma flow on the dissolution rate of cylindrical non-occlusive blood clots in an in vitro flow system and to derive a mathematical model for the process. The model was based on the hypothesis that clot dissolution dynamics is proportional not only to the biochemical proteolysis of fibrin but also to the power of the flowing blood pl...

The influence of a stationary mass flow on driven resonant MHD waves is studied for incoming slow and fast magnetosonic waves with frequencies in the slow and the Alfvén continua. In addition to the classic resonant absorption already present in a static plasma, driven resonant waves can also undergo overreflection. Depending on the strength of the equilibrium flow a variety of resonant MHD wav...

In the Hamiltonian treatment of purely mechanical systems, the canonical and actual momentum of a particle are the same. In contrast, for a plasma of charged particles and electromagnetic fields, those two momenta are different. We show how this distinction is fundamental in identifying the limitations of a recent attempt by Binney (2003) to rule out two-temperature collisionless astrophysical ...
