Background: Defective sperm function is now recognized as one of the most important causes of male infertility. Lipid peroxidation (LPO) is known to cause various impairments of sperm cells and may play a major role in the etiology of male infertility. Malondialdehyde (MDA) is one of the final products of lipid peroxidation in seminal plasma. Seminal plasma possesses a rich source of different ...

We characterize the parameters of the flowing argon plasma produced by a 16-cmdiameter plasma source utilizing a transverse magnetic filter to reduce electron temperature while maintaining the quasineutrality of the flowing plasma, as a function of the operating parameters of the source: discharge voltage, discharge current, and gas flow rate/neutral background pressure. We evaluate the plasma ...

A novel plasma treatment method/plasma source called cupping-assisted plasma treatment/ source for skin disinfection is introduced. The idea combines ancient Chinese ‘cupping’ technology with plasma sources to generate active plasma inside an isolated, pressurecontrolled chamber attached to the skin. Advantages of lower pressure include reducing the threshold voltage for plasma ignition and imp...

A 16-cm diameter plasma source operated on argon is described that is capable of producing a plasma environment that closely simulates the low Earth orbit (LEO) conditions experienced by satellites in the altitude range between 300 to 500 km. The plasma source uses a transverse-field magnetic filter, and has been successful in producing low electron temperature plasmas that contain streaming io...

Atmospheric pressure non-equilibrium water vapour plasma technology was developed, tested and partly employed for fuel conversion and production of hydrogen-rich gas. The results of experimental investigation on plasma source characteristics dependent on the anode material and prevailing external factors are presented. The effect of plasma source anode material on the elemental composition of e...

Several ion source related research and development projects are in progress at the Department of Physics, University of Jyväskylä (JYFL). The work can be divided into investigation of the ion source plasma and development of ion sources, ion beams, and diagnostics. The investigation covers the Electron Cyclotron Resonance Ion Source (ECRIS) plasma instabilities, vacuum ultraviolet (VUV) and vi...

background: in this study we have prepared the iga solution from normal human plasma using plasma fractionation and ion exchange chromatography. materials and methods: using fractionation of plasma with cold ethanol (starting with 8% ethanol), fraction iii was prepared as a suitable source for iga preparation. then it was treated with caprylic acid for separation of impurities. for enrichment o...

We present the results of measurements ionic composition plasma generated by an accelerated electron beam at medium vacuum (fore-vacuum) pressures. Calculations contribution electrons and to mechanism ionization are presented. Comparison calculated with experimental data led us conclusion about dominating process. Keywords: plasma, fore-vacuum, beam, plasma-cathode source.
