Simulations of the generation of partial nongyrotropy of newborn ions
نویسندگان
چکیده
The nongyrotropy of newborn ions in solar wind plasmas is studied by means of one-dimensional electromagnetic hybrid computer simulations of homogeneous plasmas. It is found that, contrary to the previous theory of nongyrotropy, the homogeneous injections of newborn ions can also produce the nongyrotropy of newborn ions (partial nongyrotropy). However, the inhomogeneous injections of newborn ions can make the ion nongyrotropy stronger. The newborn ion nongyrotropy is different within different perpendicular velocity range, and is strongest in the velocity range close to the injection velocity of newborn ions Vin. 2005 Published by Elsevier Ltd on behalf of COSPAR.

Extensions to Study Electrochemical Interfaces - A Contribution to the Theory of Ions
In the present study an alternative model allows the extension of the Debye-Hückel Theory (DHT) considering time dependence explicitly. From the Electro-Quasistatic approach (EQS) done in earlier studies time dependent potentials are suitable to describe several phenomena especially conducting media as well as the behaviour of charged particles in arbitrary solutions acting as electrolytes. Thi...

Objective(s): Development of the nervous system in human and most animals is continued after the birth. Critical role of this period in generation and specialization of the neuronal circuits is confirmed in numerous studies. Any pharmacological intervention in this period may result in structural, functional or behavioral abnormalities. In this study, sodium thiopental a GABA mimetic drug was a...
متن کاملOptimal Reconfiguration of Solar Photovoltaic Arrays Using a Fast Parallelized Particle Swarm Optimization in Confront of Partial Shading
Partial shading reduces the power output of solar modules, generates several peak points in P-V and I-V curves and shortens the expected life cycle of inverters and solar panels. Electrical array reconfiguration of PV arrays that is based on changing the electrical connections with switching devices, can be used as a practical solution to prevent such problems. Valuable studies have been perfor...
