The un-doped and tin (Sn) doped ZnO films were deposited by spray pyrolysis technique onto glass substrates. 0.1 M solution of zinc acetate in a mixture of ethanol and deionised water. Dopant source was tin chloride SnCl2.2H2O. The atomic percentage of dopant in solution was 2% and 4%. The effect of tin doping on the electronic transitions of ZnO films was studied. The average transmittance values for the films were (76, 84, 88) % for ZnO, ZnO:Sn 2% and ZnO:Sn 4% respectively. The optical band gaps of the films were calculated. The band gap of un-doped sample was 3.36 eV, this value decreased slightly with increasing doping concentration and became 3.17 eV for ZnO:Sn 2% and 3.1eV for ZnO:Sn 4%.

The complexation between folic acid and typical polyaromatic hydrocarbons (Acenaphthylene and Acenaphthene) was studied by using FTIR and UV spectra with pH changing. The experiments confirmed that combination was through π-π donor–acceptor interaction and inducing the protonation process in folic acid upon strengthening electron accepting ability of the acid so the changing of their charge distribution and the surroundings became necessarily. In another words, this inferred that not only biotransformation process of folic acid, but also the toxicity of polyaromatic hydrocarbons could be more understood.

In this paper a new additive fuzzy Goal programming (FGP) model is presented. In this model the objective function which makes use of non – membership functions instead of membership functions, is minimized. In the formulation, the new FGP model is transformed to that of a conventional Goal programming (GP) problem in which the decision – maker's aspiration level with tolerance for each goal can be dealt with ease. Thus the conventional GP becomes a special case of the new FGP model. This model was solved by using the computer package (Win – Qsb) respective of operational research applied.

Theoretical calculations are achieved to study the effect of different Argon pressures on various parameters for UNU/ICTP PFF, a plasma focus using Lee code. Without changing the geometry and electrical parameters of this machine which build originally to work with deuterium we compute theoretically the X – ray emission energy using argon as working gas in the machine. However, some of parameters variations in this machine are studied with changing working gas pressure.

A Theoretical Study of the Interaction between Supernovae and Their Surroundings

الخلاصة

This work presents an overview of the physics of supernovae and of their interaction with a circumstellar medium. In particular the reverse shock created by the interaction is investigated. In most types of the supernovae this shock is radiative, and due to the high temperature most of the radiation comes out as X-rays. We analyze the details of the numerical calculation of the adiabatic simulation to study the evolution of the earliest phases of a supernova explosion when the stellar atmosphere ejected by the explosion interacts with the environment of the star. This process is often called “circumstellar interaction”. The interaction depends on the properties of the wind, i.e. the wind velocity and mass loss rate of the progenitor as well as the composition of the wind. We assumed that both the supernova ejecta and the environment are spherically symmetric, which allows us to solve the problem in one dimension, with as spatial variable the radius r.

In this work, polycrystalline tin oxide thin films were prepared and studied in order to fabricate heterojunctions by growing them on n-type silicon substrates. The electrical measurements on the prepared samples were performed at different substrate and annealing temperatures. The results of these measurements showed good uniformity of these films throughout the current-voltage characteristics in both forward and reverse bias conditions at different annealing temperatures. They showed that the I-V characteristics were highly improved by thermal annealing. The reflectivity and internal quantum efficiency of the SnO2/Si were measured as functions of the incident light wavelength. As well, the short-circuit current density and open-circuit voltage were measured as functions of the incident light intensity. These measurements showed good optoelectronic characteristics of the fabricated structures stimulating to optimize their employment in solar cell applications. In addition, the low-cost production of such structures makes them very good candidates for solar energy conversion systems as cheap alternative energy techniques

The study deals with insertion of step negative or step positive reactivity and/or ramp reactivity expressed as a polynomial in time in the presence of one feedback mechanism in order to predict the neutron behavior as a function of time in terms of reactor power. Insertion of negative step reactivity such as ρ = - 0.001 $ indicates that the reactor power is stable due to this value but insertion of larger negative step reactivates causes a decrease in power as a function to time while insertion of positive step reactivity such as ρ=0.007 $ shows that the reactor power stable but it increases with time in case of insertion of large positives reactivities despite of the presence of one feedback mechanism. Also, it is observed that the resulted reactivity due to insertion of positive reactivities in the range (0.2$ - 0.4$) will be stable for any time interval without being affected by feedback mechanism. He resulted reactivity due to insertion of positive reactivities in the range (0.45$ - 0.65$) will be stable for certain time interval and then decrease due to the effect of one feedback mechanism. The sudden jump in power (excursion) is observed during very short time after inserting positive reactivities in the range of (1.003$ - 2.5$) and continues oscillations occur in the power after the excursion in case of inserting positive reactivities in the range of (1.5$- 2.5$) despite the presence of feedback mechanism. Insertion of ramp reactivities in terms of polynomial in time to study the behavior of power and/or reactivity as a function of time in the presence of two feedback mechanism (fuel) has been carried out and the result are displayed as plots, and showed this results corresponding with international results. This study appeared proceeding determination present necessarily for reactivity effects values of safety analysis in transient and for control requirements through reactor operation.

In this study, we report the quantitative phase analysis which is performed by Rietveld X-ray diffraction using “fullprof”( fullprof.2k,Version 5.00 - Jan2011-ILL JRC) program to four different samples of TiO2 . Titanium dioxide is formed of two phases, Anatase and Rutile with different weight percentage. Four samples under study , first is a nanopowder , second is thin a film ,third is the micropowder while the fourth is formed of 50:50 Anatase and Rutile TiO2 which is considered as standard. Retiveld refinement on X-ray data for the samples is performed . The obtained results have a good optimization between the observed x-ray diffraction pattern and that calculated by Retiveld. This optimization is determined according to Rp, Rwp and GOF . The accuracy check was done by examining the fourth sample by X-ray. Then, quantitative phases were calculated by comparing method which needs pure phases mixture. The final result shows that Retiveld refinement is more accurate than comparing method.
