The operational characteristics of the experimental direct current plasma torch with water vapor stabilization of the arc discharge and diagnostics of generated plasma jet at the nozzle exhaust of the torch were studied in this research. The operation parameters of the torch are presented in terms of generalized thermal and electrical characteristics, which were compared with equations for stea...

A microwave plasma was used for direct ambient ionization mass spectrometry of solid substrates, rapidly yielding atomic spectra without sample digestion or pre-treatment. Further, molecular spectra for the organic components of the substrate were obtained simultaneously, in an ambient ionization format. Initial characterization of the microwave plasma coupling to an ion trap mass spectrometer ...

Extensive testing with a plasma torch operating on methane in a supersonic crossflow sparked an interest in modeling the torch using CFD to determine if methane plasma jets can be accurately modeled, and if so, to ascertain the usefulness of such results. The comparison presented here is of a methane plasma jet produced by a normally oriented plasma torch in a Mach 2.4 crossflow and the corresp...

Quantum dot is a special kind of nanomaterial composed of periodic groups of II-VI, III-V or IV-VI materials. Their high quantum yield, broad absorption with narrow photoluminescence spectra and high resistance to photobleaching, make them become a promising labeling substance in biological analysis. Here, we report a quick and parallel analytical method based on quantum dots for ToRCH-related ...

Most intrauterine infections are acquired through the placenta, although transvaginal bacterial infections may also occur. The TORCH eponym remains a good reminder for these entities, identifying toxoplasmosis, others, rubella, cytomegalic virus, and herpes simplex. A second H for HlV or perhaps the words A (AIDS) TORCH should now be used, as AIDS becomes the most common maternally transmitted ...

background: our aim was to detect the rate of toxoplasma gondii infections and the coinfections in childbearing age women in turkey accompanying using seroprevalence data from a multicenter hospital setting. methods: overal, 17751 childbearing age women through 16-45 years were included to the study between 2004 and 2010. the clinical samples of the patients were collected from 16 hospitals and...
