Abstract: The application and characteristics of relatively big volume plasma produced with cathodic glow discharges taking place across a gaseous envelope over the cathode which was dipped into electrolyte in hydrogen generation were studied. A critical investigation of the influence of methanol concentration and voltage across the circuit on the composition and power consumption per cubic meter of cathode liberating gas was carried out. The course of plasma under-liquid electrolysis has the typical characteristics of glow discharge electrolysis. The cathode liberating gas was in substantial excess of the Faraday law value. When the voltage across the circuit was equal to 550 V, the volume of cathodic gas with sodium carbonate solution was equal to 16.97 times the Faraday law value. The study showed that methanol molecules are more active than water molecules.The methanol molecules were decomposed at the plasma-catholyte interface by the radicals coming out the plasma mantle.Energy consumption per cubic meter of cathodic gases (WV) decreased while methanol concentration of the electrolytes increased. When methanol concentration equaled 5% (ψ), WV was 10.381×103 kJ/m3, less than the corresponding theoretic value of conventional water electrolysis method. The cathodic liberating gas was a mixture of hydrogen, carbon dioxide and carbon monoxide with over 95% hydrogen, if methanol concentration was more than 15% (ψ). The present research work revealed an innovative application of glow discharge and a new highly efficient hydrogen generation method, which depleted less resource and energy than normal electrolysis and is environmentally friendly.
Plasma Degradation of 1-Naphthylamine by Glow-discharge Electrolysis

Pakistan Journal of Biological Sciences , 2004,
Abstract: A new method for degradation of 1-naphthylamine by glow discharge electrolysis is proposed. The degradation process was examined by using ultraviolet (UV) absorption spectrum and high performance liquid chromatography (HPLC). The chemical oxygen demand (COD) of sample was also measured. The results showed that 1-naphthylamine can be removed completely within 40 min in the absence of Fe2+ and within 2 min in the presence of Fe2+. The optimum voltage used was at 600 V. The concentration of Fe2+ ion and the pH of solution exhibit an appreciable effect on the degradation rate. The COD of degradation sample was even higher than the original sample. This is because the benzene rings or naphthalene rings were destroyed and some organic acids were produced in this process.
Neutrino orbital angular momentum in a plasma vortex  [PDF]

Physics , 2008, DOI: 10.1209/0295-5075/84/41001
Abstract: It is shown that an electron-neutrino beam, propagating in a background plasma, can be decomposed into orbital momentum (OAM) states, similar to the OAM photon states. Coupling between different OAM neutrino states, in the presence of a plasma vortex, is considered. We show that plasma vorticity can be transfered to the neutrino beam, which is relevant to the understanding of the neutrino sources in astrophysics. Observation of neutrino OAM states could eventually become possible.
Evolution, probabilistic interpretation and decoupling of orbital and total angular momenta in nucleon  [PDF]

Physics , 1998,
Abstract: The leading order evolution of parton orbital angular momenta is treated in the probabilistic manner. As a result, the splitting probability matrix, while coinciding with the recent explicit calculations, is expressed in the terms of the standard spin-dependent and spin-averaged kernels. The implied relations between spin and orbital angular momenta evolution kernels may be interpreted as resulting from the ambiguity in the separation of the angular momenta to the spin and orbital contributions and are likely to be valid for higher orders and twists. Consequently, the orbital and total angular momenta may be considered as decoupling from the spin ones, the latter being the only elements of nucleon structure accessible via the hard scattering of polarized particles. In particular, the partition of the total angular momenta of quarks and gluons should be analogous to that of their momentum at any $Q^2$, generalizing the earlier finding for asymptotic limit by Ji, Tang and Hoodbhoy.

Abstract: Glow discharge electrolysis degradation of Eosin B solutions has been investigated. Ultraviolet (UV) absorption spectra, fluorescence spectra (FS), pH meter and atomic force microscopy (AFM) are used to monitor the degradation process. A simple degradation mechanism for Eosin B is proposed on the basis of UV, FS, pH and AFM. It has been found that Eosin B is completely mineralized into CO_ 2 , H_ 2 O and inorganic compound. Within 110 min, the decolorization rate at 513 nm is 95%. The values of pH in the solution are decreased during the degradation process due to the carboxylic acids formed. The reaction constant k is calculated to be 0.0206 min~ -1 by absorbency values, and the reaction may follow well first order kinetics.
Electron Orbital Theory for an Alternative Interpretation of Low-pressure Hurricane Systems
Marine Science , 2012, DOI: 10.5923/j.ms.20120205.03
Abstract: Hurricanes, cyclones and typhoons are weather phenomena which induce damages for billions of dollars yearly and pose significant risks to communities worldwide. The need for better meteorological prediction methods is therefore more important than ever, particularly with the emergence of “extreme weather” conditions. Super-computer methods are key tools for storm-analysis and prediction, and are used frequently to predict the direction of large low-pressure systems such as Hurricanes heading yearly for American continent, cyclones in Australia and typhoons in Japan. The dynamical behaviour of these vast low-pressure systems is not fully understood, and the directions of these weather phenomena are often resolved too late for evacuation procedures to be fully effective. In order to increase the understanding of low-pressure systems and meteorological prediction, a hybrid view on the behaviour of hurricane systems based on a blend of quantum mechanics and classical physics is introduced in this brief note. The aims are to introduce a mathematical contemplation to bring to the attention of meteorological modelers a putative behaviour of the storm systems analogue with electron orbital density functional theory, and to use electron orbital theory to improve the resolution and predictive power of storm modeling. The mathematical discussion presented herein shows that a low-pressure system can be subdivided into N-layers, with physical and energetical qualities. Such qualities comprise angular momenta and individual energies of high-density regions which can be used to predict the direction of the low-pressure system. The results and mathematical discussion presented herein serve as a foundation for Hurricane theory improvement.

Abstract: Solid-phase microextraction coupled GC/MS was investigated for the determination of 2,4-dinitrophenol in aqueous sample. Analytes were extracted by a 85 microns polyacrylate coated fiber. The fiber was then transferred into the injector of GC. Analytes were thermally desorbed and detected by GC/MS. The influences of several parameters on SPME procedure have been studied. The optimization condition was obtained: directly sampling in the water sample with the extraction period was 30 min and the desorption time 3 min at 270 degrees C. Acidification by hydrochloric acid (pH 2) and saturated salt were necessary for the best sensitivity. The precision of SPME is better than that of liquid-liquid extraction. This method is a fast, simple, and pre-concentration-free technique, which is suitable for detecting 2,4-dinitrophenol in water sample.
Photon Orbital Angular Momentum and Mass in a Plasma Vortex  [PDF]

Abstract: We analyse the Anderson-Higgs mechanism of photon mass acquisition in a plasma and study the contribution to the mass from the orbital angular momentum acquired by a beam of photons when it crosses a spatially structured charge distribution. To this end we apply Proca-Maxwell equations in a static plasma with a particular spatial distribution of free charges, notably a plasma vortex, that is able to impose orbital angular momentum (OAM) onto light. In addition to the mass acquisition of the conventional Anderson-Higgs mechanism, we find that the photon acquires an additional mass from the OAM and that this mass reduces the Proca photon mass.

Abstract: We present a detailed analysis and interpretation of the high-mass binary V380 Cyg, based on high-precision space photometry gathered with the Kepler space mission as well as high-resolution ground-based spectroscopy obtained with the HERMES spectrograph attached to the 1.2m Mercator telescope. We derive a precise orbital solution and the full physical properties of the system, including dynamical component mass estimates of 11.43+/-0.19 and 7.00+/-0.14 solar masses for the primary and secondary, respectively. Our frequency analysis reveals the rotation frequency of the primary in both the photometric and spectroscopic data and additional low-amplitude stochastic variability at low frequency in the space photometry with characteristics that are compatible with recent theoretical predictions for gravity-mode oscillations excited either by the convective core or by sub-surface convective layers. Doppler Imaging analysis of the silicon lines of the primary suggests the presence of two high-contrast stellar surface abundance spots which are located either at the same latitude or longitude. Comparison of the observed properties of the binary with present-day single-star evolutionary models shows that the latter are inadequate and lack a serious amount of near-core mixing.

Pakistan Journal of Biological Sciences , 2005,
Abstract: The main purpose of this study was to conduct experimental investigation of water disinfection by using the electrolysis method. Inactivation and killing Coliform in polluted waters are investigated by different voltage, electrodes (Al, St and Cu) and 5 min electrolyze time. The experimental results showed that the removal efficiency depends on the voltage and electrode materials. From the experiments carried out at 10 V and at current intensity of 135 mA, it was found that 5 min period was sufficient for disinfecting water by Stainless steel electrodes.
