  • Analysis of elastic scattering data below, atop and above the delta
           resonance using inverse scattering theory

    • Abstract: The simple local optical potential adopted in analyzing successfully elastic scattering data in the delta resonance region has been emphasized here. This is based on obtaining the same nature for the potential by extracting potential points from available phase shifts at 114, 163, 240 and 340 MeV using inverse scattering theory within the framework of Klein-Gordon equation. Luckily, and as e...

  • Dielectric study of calcium doped barium titanate Ba1-xCaxTiO3 ceramics

    • Abstract: Calcium doping effect on the ferroelectric properties of Ba1-xCaxTiO3: BCTx (x = 0.01, 0.05, 0.1) ceramic material prepared via the sol-gel process was studied. X-ray diffraction (XRD) showed that the powders of calcined BCTx at 900C crystallize in a pure phase of perovskite type without secondary phases. Microstructural morphology was analyzed by Scanning Electronic Microscopy (SEM). Dielec...

  • A new solitary wave solution of the perturbed nonlinear Schrodinger
           equation using a Riccati-Bernoulli Sub-ODE method

    • Abstract: The Riccati-Bernoulli Sub-ODE method is used for the first time to investigate exact wave solution of the perturbed nonlinear Schrodinger equation with Kerr law non linearity which describes the propagation of optical solitons in nonlinear optical fibers that exhibits a Kerr law non linearity. An infinite sequence of exact solutions can be obtained according to Backlund transformation. The p...

  • Space charge kinetic treatment in Langmuir probes with cylindrical

    • Abstract: In this paper, an analysis of the space charge build up in the interelectrodic region of a velocity analyzer with cylindrical symmetry is performed using kinetic theory. Thus the present treatment includes temperature effects. Azimuth symmetry is also assumed. A detailed and comparative analysis, between planar and cylindrical electrodes, is carried out, showing the advantages of each kind o...

  • Investigating H and Z geomagnetic component disturbance field in the

    • Abstract: The relationship in the variations of geomagnetic horizontal component (H) and vertical component (Z) in Boulder station (40.1N, 254.8) has been investigated. In the analysis, series of significant changes in amplitude and period are observed in H as well as in Z during the day-time. The changes in H and Z for the average yearly diurnal variations and for the monthly variations do not exhibi...

  • Biodegradation with heterogeneous catalyst in the production of biogas
           from wheat wastes, rice husk and spent grains

    • Abstract: Biodegradation with heterogeneous catalysts were successfully carried out in the production of biogas from wheat wastes, rice husk and spent grains. Five digesters were charged with spent grains/clay soil, spent grains/lime stone, rice husk/clay soil, rice husk/lime stone and wheat wastes/potash, respectively. Clay soil, limestone and potash were used as catalysts for optimizing and to speed...

  • Analytical model of heavy-particle pollutant transport in estuary

    • Abstract: The aspects of heavy-particle diffusion in the tropical estuary is investigated. The two dimensional advection-diffusion equations with tidal and settling velocity were solved with steady state approximation. An analytic solution was obtained in term of Cosines Integral function. The results showed that the profile of concentration follow a tidal cycle with the concentration decrease when th...

  • Empirical model for estimation of global radiation from sunshine duration
           of Ijebu-Ode

    • Abstract: Empirical models to estimate global solar radiation require the development of a set of equations that relate it to other meteorological parameters and from the monthly average daily value of clearness index and relative sunshine spanning of a period of 5 years, the Angstrom- Prescott model was developed for the estimation of global solar radiation of Ijebu-Ode (Lat. 6.81⁰N. Long. 3.92⁰E), a...

  • Spectroscopic determination of the electrical parameters of a micro-wave
           discharge in helium plasma

    • Abstract: This paper is based on the study of the emitted radiation by electrical discharge plasma, caused in the helium a pressure of 4.8 Torr, a power MW of 108W. The study numerical model allows the identification of several spectral lines. With the Boltzmann method the study have calculated the electronic temperature (Te=3.23eV), it corresponds to the classification scale of plasmas. The applicati...

  • Extraction and characterization of biodiesel from Borassus aethiopum and
           Cassia sieberiana

    • Abstract: Biodiesel was successfully produced from Borassus aethiopum and Cassia sieberiana seeds using the trans-esterification method. The biodiesels produced were characterized by physico-chemical properties of acid value, iodine value, specific gravity, refractive index, viscosity, density, flash point, cloud point and pour point. Results showed that the biodiesels produced have values which compa...
