  • The Biological Effect of a Class of Alternating Magnetic Field on Life
           Field Using Distilled Water as Test Materials

    • Authors: Alli-Balogun A. S.
      Abstract: This study investigated the biological effect of a class of alternating magnetic field on life field using distilled water as test materials. Extremely low frequency magnetic field (ELF - MF) was carried out using a 50Hz AC power as the source, and a self made copper wire solenoid (magnetic chamber) inside which the sample was placed. A variable transformer was used to vary the current in the magnetic chamber to achieve different field intensities. The results indicate that magnetic field affects the rate of solubility of salts in water as well as an alteration in its pH. This study supports initial reports that extremely low frequency magnetic field alters the physiochemical properties of water. Keywords: magnetic field, life field, distilled water, biological effect

  • Superposed Degenerate Parametric Oscillator with Coherent Light

    • Authors: Yimenu Yeshiwas
      Abstract: In this paper, we have studied the statistical and squeezing properties of the light produced by superposed light beams generating by a pair of degenerate parametric oscillator whose cavity mode is driven by a coherent light and is coupled to a vacuum reservoir via a single port mirror. We obtain c-number Langevin equation associated with the normal ordering using the pertinent master equation. Employing the solution of the c-number Langevin equation and the density operator, we have determined the mean and the variance photon number, quadrature variances and squeezing spectrum of the superposed light beams.

  • Superposed Two-mode Squeezed Laser Light Coupled to Squeezed Vacuum

    • Authors: Sitotaw Eshete
      Abstract: The squeezing and statistical properties of a pair of superposed non-degenerate three-level lasers coupled to a squeezed vacuum reservoir could be analyzed with the help of the density operator for a pair of superposed two-mode laser light. We have determined the quadrature variances of the cavity modes. The results show that the light produced by the system under consideration is in squeezed state. According to our work, the quadrature squeezing for a pair of superposed laser light beams is found to be the average of the quadrature squeezing of the separate lasers. The presence of squeezed vacuum reservoir enhances the quadrature squeezing significantly. Keywords: Density Operator, Laser, Reservoir, Squeezing, Two-mode light

  • A Study of Structural Properties of CuMn2O4 Synthesized by Solid State

    • Authors: Rasha Yousef
      Abstract: CuMn2O4 was synthesized by Solid State method. MnO2 and CuO were used as precursors. The temperature of synthesis was 850°C. X-ray diffraction analysis (XRD) revealed that the CuMn2O4 was synthesized. XRD results showed that the prepared compound was polycrystalline and had cubic structure. The lattice constant was a=8.359 . The volume of unit cell was V=584.14 A°3. The space group of symmetry was determined from JCPDS data and it was Fd3m. The results show that there are a compressive strain at 750°C and 950°C and tensile strain at 850°C. It was revealed from differential thermal analysis that the physical water was removed at 134.30°C. The thermal characteristic of prepared compound showed that the formation of it starts after (700)°C. DTA data revealed that the 850°C was the optimum degree of synthesis of CuMn2O4 which agree with XRD results. the compound decomposes at 950°C. Keywords: copper manganite (CuMO), mixed oxides, solid state reaction, spinel.

  • Study of Effect Concentration of Ethanol Vapor on Sensing Properties of
           Nano Powders Zinc Oxide Films

    • Authors: Wael ABDULLAH
      Abstract: The purpose of this research is study the effect concentration of ethanol vapor on Sensing Properties of nano powders Zinc Oxide thick films. So three thick films have been prepared by the chemical painting method from Zinc Oxide nano powders as the source compound their dimensions of particle about (166.47, 34.7, 36.23nm), nano powders of Zinc Oxide are prepared by milling in a high energy ball mill for various spans of time (1-18h) on cleaned glass substrates under limited thermal conditions. The sensitivity depends on adsorption reactions and chemical or physical desorption, and photo absorption reactions, and chemical reactions that occur on the surface or within the sensor material. These reactions lead to specific physical changes in the sensor which can be analyzed. This identification process can be carried out using several different principles such as conductivity, electrical polarography, electrochemical activity, photo and magnetic properties, and electrical isolation properties. .The films have been investigated for their sensing properties relating to 200ppm ethanol vapor adsorption using the (I–V) characteristics in air and in the presence of ethanol vapor using KEITHLEY 237 device .The temperature of the films has been changed from 50°C to 350°C we note improving in sensitivity of three films with increasing temperature until specific temperature degree, then we note that the film which dimensions 34.7nm has high sensitive among three films at 250°C .We note that improves the sensitivity of the film with an increased concentration and the operating temperature of film has decreased with increased concentration Keywords: Zinc Oxide (ZnO), Ethanol Vapor, Sensing properties.

  • The Effect of Debye Sphere Potential on Electron Scattering by Ions in
           Tokamak using Born Approximation

    • Authors: Achmad Fajar Putranto, Muhammad Nur, Asep Yoyo Wardaya
      Abstract: Scattering in plasma is caused by Debye sphere potential effect in the aftermath of the changes in plasma species density to form Debye sphere. In Debye sphere, the scattering of electron by ions occurs in multiple ways (multiple scattering) as the amount of ions in Debye sphere. The perceived kinetic energy of electron is dominated by thermal perturbation that is affected by temperature so that the greater temperature thus the greater kinetic energy of the projectile particle. In tokamak plasma condition, it can be assumed that the kinetic energy of electron is much greater than the perceived potential energy of electron due to the ions Debye sphere potential thus Born approximation can be used. By using mathematical condition of Born approximation validity, it is obtained that the limit of electron multiple scattering by ions in which Born approximation is still valid is 3 times multiple scattering. Furthermore, it was found that the differential cross-section for electron scattering by ions is large at small angle scatterings 0°<θ<90° and small at large angle scatterings 90°<θ<180° which means that the form of potential interaction is not a Coulomb potential interaction but Debye sphere potential interaction that mathematically form Yukawa-like potential because the scattering occurs much more frequently at relatively long distance in which the scattering still occurs. It is obtained that the total cross section for electron scattering by ions is 2.81╳10-10 m2. Keyword : Plasma, Debye sphere, Scattering, Multiple scattering, Born approximation
