Abstract

Thin films of Bi2-x(CuPb)xSr2Ca2Cu3O10+ compound (x  0, 0.1, 0.2, and 0.4) were prepared by Pulse laser deposition (frequency 6 Hz, energy 500mJ, pulses 500, vacuum 101 Tor and 1 Cm distance between the substrate and the target) at room temperature of 300 nm thickness onto cleaned glass substrates. Optical measurements for all values of x indicate the same value of transmittance (97.76) but at different positions of wavelengths with shifting towards short wavelength within the extreme wavelength range (200-1100) nm. High optical energy gap for films is at x  0. The reflectance approaches to zero at for all values of x. Atomic force microscopy and photoluminescence for the films are studied.

Abstract

In this paper, the measurement of specific activity concentrations of five commercial oil samples obtained from different countries (Kuwait, U.A.E., Iran, and Germany) were carried out using (HPGe) detector. From the measurement it was observed that average values of specific activity concentrations for 238U, 232Th and 40K were equal to (20.2061.4 Bq/l), (20.0803.5 Bq/l) and (162.12049.2Bq/l), respectively. The results were less than their corresponding recommended global values reported by (UNSCEAR, 1994) publication. The radiation hazard indices [Iɣ, Hin, Hex, Raeq, DƔ, (AEDE)in and(AEDE)out] were also studied, and all the obtained results and their average value were also observed to be lower than their corresponding average values given by (UNSCEAR,1994, 2000). Finally, the excess life time cancer risk (outdoor), (ELCR), results were found to be ranged from 0.102103 (Al-Khaleej) (Kuwaiti origin) sample to 0.147103 (Vulcan 330) (Iranian origin) sample, with an average value of (0.1210.012)103, which were less than the world average value. Thus, the results of the present work have shown that, all the studied samples of motor oil are safe when used.

Abstract

The leaves of the Capparisspinosa were collected from the eastern Radwaniya/Baghdad duringthe months April, May, June, July, September, and September. The leaves were extracted by water and alcohol. The effectiveness of anti-tumor and anti-leishmania for the water and alcohol extracts of al-Qabar leaf samples for May and September, which were characterized by the highest percentage of active compounds for the rest of the tested months, was evaluated by adopting the results of a previous study for the same researchers or chemical composition and leaf content of active compounds The concentrations of 250, 500, 1000 mg.L1 were evaluated for anti-tumor efficacy. The anti-leishmania efficacy was tested at 250, 500 and 1000 mg L1. The sample of the alcohol extract for May collected complex showed the highest anti-tumor activity at 63.5% at 500 mg.L1and the highest efficacy of the samples of alcohol extract for September was 56.1% at the concentration of 250 mg.L1, while the water extract for the May sample did not show any effectiveness even at the highest concentration 1000 mg L1, but the September collected sample was effective at 49.3% In the case of the inhibitory efficacy of leishmania, the alcohol extract of the May sample did not show on inhibitory activity at the lowest concentration. The effectiveness of 41.3% was observed at 500 mg.L1, but decreased to 14.8% at the highest concentration of 1000 mg L-1. Of the same month at the lowest concentration of 37.8% and decreased effectiveness there was an increase in the anti-leishmania effect of the September extract of the sample with increased concentration. There was of its effectiveness at the lowest concentration of a user and then reached 8 and 37% at the concentration of 500 and 1000 mg.L1 with the same percentage, and the water extract for the September sample did not show any efficacy at the minimum and highest concentrations, except the concentration of 500 mg.L1, which reached 11%.

Abstract

This paper presents an approximate solution of ordinary boundary value problems using the variational iteration method. The fractional derivatives are described in the Caputo sense, because it allows traditional initial and boundary conditions to be included in the formulation of the problem. The solutions of proposed fractional equations are calculated in the form of convergent series with easily computable components. Also, we construct the variational iteration formula and its convergence to the exact solution for solving system of fractional order differential equations. Some examples are solved as an illustration to the method, in order to show the accuracy of the method and comparison with results the exact solution for the given test problems, which are given for comparison purpose.

Abstract

In this paper we will discuss the mixture distribution consisting of two Inverse Exponential Distributions (MTIED) based on fuzzy data. We will study the Maximum Likelihood Estimator (MLE) via the Newton Raphson (NR) algorithm and Bayes estimation under square error loss and quadratic loss functions for the unknown parameters of the distribution, and reliability function. The obtained estimates of the unknown parameters and reliability function are compared numerically through Monte-Carlo simulation study in term of the mean square error (MSE) values and (IMSE) respectively.

Let R be an associative ring with identity, and let M be a unitary left R-module. The main purpose of this paper is to introduce and study properties of class of modules including lifting module. We use the Radical submodule to introduce this class of modules. We start by defining a generalized lifting module as a generalization of lifting module, then we give another generalization of generalized lifting module we called it cofinitely generalized lifting module. Thus, we give characterization and prove some properties of this type of modules.

In this work, we have studied a class of nonlinear Riccati differential equation which is used as mathematical models in many physically significant fields and applied science. The homotopy perturbation method, has been modified for solving generalized linear and nonlinear Riccati differential equation, which is a second-order ordinary differential equation. Also, we have tested the modified homotopy perturbation method on the solving of different implementations which are show the efficiency and accuracy of the proposed method. The approximated solutions are agreed well with analytical solutions for the tested problems.

Abstract

In this paper, the classical and pre-Lie Magnus expansions have been studied, discussing how one can find a recursion for the pre-Lie case which already incorporates the pre-Lie identity. A combinatorial vision of a numerical method proposed by S. Blanes, F. Casas, and J. Ros in [4], has been given on a writing of the classical Magnus expansion in a free Lie algebra, using a pre-Lie structure.

Abstract

In this paper concerned with the solution of the nanoscale structures consisting of the InAs⁄GaAswith an effective mass envelope function theory, the electronic states of the InAs⁄GaAs quantum ring are studied.In calculations, the effects due to the different effective masses of electrons in and out the rings are included. The energy levels of the electron are calculated in the different shapes of rings, i.e., that the inner radius of rings sensitively change the electronic states. The energy levels of the electron are not sensitively dependent on the outer radius for large rings. The structures of InAs⁄GaAs quantum rings are studied by the one electronic band Hamiltonian effective mass approximation, the energy-and position-dependent on electron effective mass approximation, and the spin-dependent on the Ben Daniel-Duke boundary conditions. In the description of the Hamiltonian matrix elements, the Finite elements method with different base piecewise linear function is adopted. The non-linear energy confinement problem is solved approximately by using the Finite elements method with piecewise linear function, to calculate the energy of the one electron states for theInAs⁄GaAs quantum ring. The results of numerical example are compared for accuracy and efficiency with the finite element method of linear triangular element. This comparison shows that good results of numerical example.
