This work experimentally investigates the dissociation of CO2 in an atmospheric pressure surface-wave discharge. A 2-kW microwave power supply is used to sustain the plasma contained in 1-cm-diameter quartz tube. Optical emission spectroscopy is recorded at varying axial positions along the quartz discharge tube to give evidence of the different species present. Diagnostics taken with a residua...

Purpose: To investigate the effect of β-glucuronidase on the extraction efficiency of silymarin (mainly as silybin) from spiked human plasma using a sensitive and reproducible high performance liquid chromatography (HPLC) method. Methods: The importance of β-glucuronidase was evaluated by comparing the extraction efficiency of silymarin in β-glucuronidase-treated and untreated plasma samples. I...

Configuration of plasma reactors influences the generation of active species including the energized electrons, active radicals and the distribution of active species in reactor, and thus influences the removal efficiency of pollutants. Oxidation efficiency of elemental mercury (Hg) in two different DBD plasma reactors was studied in this paper. One plasma reactor is a surface discharge reactor...

In previous studies, mebudipine, a dihydropyridine calcium channel blocker, showed a considerable potential to be used in cardiovascular diseases. The aim of the current study was to develop a valid method using reversed-phase high performance liquid chromatography coupled with electrospray ionization mass spectrometry to assay mebudipine in the human plasma. Separation was achieved on a Zorbax...

An advantageous plasma-catalytic setup was developed and applied towards the degradation of trifluralin in soil. For first time, TiO2 ZnO catalysts were compared when employed conjunction with micro-discharges generated directly into interconnected soil channels. In presence catalysts, a significant increase efficiency observed; after 5 min, increased from 66.5% (plasma alone) to 94.2% 93% addi...

fifteen holstein male calves (416 ± 35 kg initial bw; mean ± sd) were employed in a replicated 3 × 3 latin square test to investigate the effect of partial replacement of barley grain by wheat factory sewage (wfs) within three 22-d periods including 16 d of adaptation and 6 d of data collection. the basal diet (wfs0) consisted of 42.5% (dm basis) barley grain, partially replaced with either 23....
