The floating potential of an emissive cylindrical probe in a plasma is calculated for an arbitrary ratio of Debye length to probe radius and for an arbitrary ion composition. In their motion to the probe the ions are assumed to be collisionless. For a small Debye length, a two-scale analysis for the quasineutral plasma and for the sheath provides analytical expressions for the emitted and colle...

The input impedance of a large circular loop antenna with arbitrary orientation in a cold magnetoplasma is calculated by using a transmission line theory. New impedance resonances for antennas of finite size in a magnetoplasma in the frequency region below and near the electron cyclotron frequency are indicated theoretically. The resonance peak of the impedance at the lower hybrid resonance fre...

Abstract. The article describes results of experimental study of a plasma jet with the use of electric probes. The volt-ampere probe characteristics were determined from measurements with slowly varying biasing potential in the probe circuit. Plasma floating potential and plasma resistance in different positions in the vicinity of plasma jet were determined for various pressures of ambient atmo...

Objective(s): In this study, a cocktail of probe drugs was used to assess whether lentinan could influence the activities of rat enzymes CYP3A4, CYP2D6, CYP1A2, CYP2C19, and CYP2C9 in vivo. Materials and Methods: Fourteen days after intraperitoneal injection of lentinan, rats were given an oral dose of a cocktail solution containing phenacetin, tolbutamide, omeprazole, metoprolol, and midazolam...

Electrostatic-force-sensitive scanning probe microscopy (SPM) is used to investigate grain boundary behavior in polycrystalline BiFeO3 ceramics. Scanning surface potential microscopy (SSPM) of a laterally biased sample exhibits potential drops due to resistive barriers at the grain boundaries. In this technique, the tips acts as a moving voltage probe detecting local variations of potential ass...

We consider the simulation of the thermal and electrical processes, involved in the radio-frequency (RF) ablation procedure. RF ablation is a low invasive technique for the treatment of hepatic tumors, utilizing AC current to destroy the tumor cells by heating. The procedure consists of inserting an RF probe in the patients liver and attaching a ground pad to the skin. After that the AC current...

Plasma electrolytic oxidation is a powerful technique allowing the formation of ceramic coatings with high degree functionalization. Plasma–chemical interactions, resulting from application voltage in conductive electrolyte, like 0.5 M NaOH, favor development porous surface, which deserves to be sealed obtain proper corrosion resistance. In present work, effect temperature employed during seali...
