in this paper, construction of triplet atmospheric plasma jet using argon, air, oxygen and nitrogen gases is reported. bactericidal effect of the plasma jet is also investigated. to that end, longitudinal geometric configuration for the electrodes was chosen because it would increase the jet length. electrical characteristics, jet length dependencies on the applied voltage and gas flow rate wer...

language teachers usually face issues regarding the most effective methods of teaching. teaching language to nonnative speakers of english involves certain problems and challenges at all levels of instruction. due to the unsatisfactory results of focus on forms and focus on meaning instructions and their inevitable inadequacies, focus on form instruction along with its multiple techniques are r...

We investigate the linear dynamics of an electromagnetic field propagating in curved spacetime presence plasma. The dynamical equations are generically more involved and richer than effective Proca equation adopted as a model previous work. discuss general focus on case cold plasma background spherically-symmetric black hole, showing that system admits plasma-driven, quasibound states prone to ...

normal 0 false false false en-us x-none ar-sa background: carbamazepine has been used as aeds since 1965, and is most effective against partial seizures. two basic mechanisms of action have been proposed: 1) enhancement of sodium channel inactivation by reducing high-frequency repetitive firing of action potentials, 2) and action on synaptic transmission. the aim of this study was to provide a ...

This article reports on selected findings from a qualitative study of factors affecting the academic success of Black male students in the community college. Data from this study was collected through semistructured interviews with 28 participants at Desert Valley Community College (SVCC) (a pseudonym). SVCC is a midsized institution located in the Southwestern United States. Findings address t...

The expected emission spectra of xenon plasma have been studied for different conditions using FLYCHK code. Expected xenon plasma spectra at certain electron temperature range have been plotted. The suitable electron temperature ranges for xenon plasma soft X-ray emission and extreme ultraviolet emission have been investigated. The X-ray ratio curves for various electron temperatures with proba...

The neutron and x-ray production is investigated in various pulse-power devices for a deeper understanding of the ion electron acceleration mechanisms application pulsed sources. We present extensive results from an anode shape experiment carried out on PFZ-200 plasma focus device. shapes anodes were tested, including cylinders, tapers, or rounded tips. experimental shots with peak current abov...
