Final-state interaction and screening have a great influence on qq̄ production cross sections, which are important quantities in many problems in quark-gluon plasma physics. They lead to an enhancement of the cross section for a qq̄ color-singlet state and a suppression for a color-octet state. The effects are large near the production threshold. The presence of screening gives rise to resonances...
Production and Acceleration of Plasma by Electron Cyclotron Resonance (Coaxial Microwave Plasma Gun)
Background and Objectives: Cold plasma is used as an innovative solution in production and distribution of healthy and high-quality foods. Objectives of this study were to use cold plasma technology as a method for the structural modification of corn starch and its functional assessment in food models. Materials & Methods: Starch granules were treated with plasma with two various gases in the ...
The present studies were undertaken to assess the relative effects of free fatty acid (FFA) availability, glucagon excess, and insulin deficiency on ketone body (KB) production in man. To determine whether an increase in FFA availability would augment KB production in the absence of insulin deficiency and glucagon excess, plasma insulin and glucagon were maintained at basal concentrations by in...
A non-equilibrium plasma assisted combustion system was developed by integrating a counterflow burner with a nano-second pulser to study the effects of atomic oxygen production on the extinction limits of methane diffusion flames at low pressure conditions. The production of atomic oxygen from the repetitive nano-second plasma discharge was measured by using two-photon absorption laser-induced ...
the experimental studies of methane conversion to higher hydrocarbons and methanol using a dielectric barrier discharge (dbd) reactor are presented in this article. the process is carried out at ambient atmospheric pressure and temperature. the dbd reactor is stimulated by an alternative voltage of 50 hz and amplitude of max.23kv. the examination of the effect of voltage and flow rates on metha...
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...
The net uptake and output of plasma unesterified choline, glycerophosphocholine, phosphocholine and lipid choline by organs of the conscious chronically catheterized sheep were measured. There was significant production of plasma unesterified choline by the upper- and lower-body regions and the alimentary tract and uptake by the liver, lungs and kidneys. The upper- and lower-body regions draine...
Dogma holds that plasma cells, as opposed to B cells, cannot bind antigen because they have switched from expression of membrane-bound immunoglobulins (Ig) that constitute the B-cell receptor (BCR) to production of the secreted form of immunoglobulins. Here we compare the phenotypical and functional attributes of plasma cells generated by the T-cell-dependent and T-cell-independent forms of the...
