In this paper, a theoretical model for electron transport through symmetric system consisting of two baths interferometer with one single-level quantum dot in each of its arms was considered. In this model, the dots are attached to ferromagnetic leads with parallel and antiparallel magnetic configurations. Green's function technique in this model was used. Our focus is on the Transport characteristics of conductance (G) and tunnel magnetoresistance (TMR). A special attention to the influence of an applied magnetics flux on the characteristics of conductance and tunneling magnetoresistance was paid. Concerning the study of the conductance, it was found that the effect of bonding (antibonding) states is most obvious in quantum dots at various values of the magnetic field. The change in spin-polarization value was seen to affect the increase and decrease in the conductance value. We noticed a difference in calculation of TMR in the bonding and the antibonding states, where the results show Strong dissonance in bonding state and strong attraction in antibonding state.

In this work, the chromodynamics (QCD) theory was used to investigate the photon rate which was produced in interactions of anti-charm with gluon. The simple quantum scenario theory was implemented to give the rate equation that describes the collision of quark and gluon at a chemical potential .The photon emission rate was evaluated from the anti-charm-gluon interaction of the cg → dγ collision at the temperature of the system in the range of 180 - 360 MeV with different critical temperatures (e.g. 116.575, 139.891, 157.377 and 174.863 MeV) with photons energy GeV under the assumption that fugacity of quark and gluon are =0.08 and =0.02 respectively . The photon rate increases with decreasing the coupling of quark and gluon according to a decrease in the temperature of the system from 360 MeV to 180 MeV. The photon emission spectrum was calculated and discussed using a photon energy of 1GeV to 10GeV with different critical temperatures. In terms of QCD theory, the quantitative accomplishment was made for a unique six-flavor number nf = 4 + 2 of photon emission. The photon rate reaches minimum with photon energy E=10 GeV, it reflects the less coupling for the cg → dγ interaction.

Abstract Endovenous laser ablation therapy (EVLA) relies heavily on the power of the laser used. Therefore, the relationships between this power and other related parameters can be studied and taken into account in order to obtain successful results from the treatment. Not only the related parameters should be tested and examined, but some other parameters that may appear unrelated to the success of the EVLA treatment should also be studied in order to improve and succeed the venous treatment. Thus, the correlation coefficient between the applied laser power and age/gender was calculated in this study. The purpose of this study was to compare the laser power used in the EVLA procedure with age for the two genders. 42 patients who suffered from venous ulcers in the lower limbs of the human body were treated with a 1470-nm diode laser. So, the correlation coefficient was for males and for females.

According to a framework, the interaction is prominent between the two parameters (and). This means that vibrational structures are constant rises with opposite of rotational. Thus, the potential energy surfaces are considered as a pointer of and distortions for even-even and isotones. The behaviors of the potential energy surfaces with minimum β (-0.84356,- 0.39928, and -0.19045) have circular contours centered at this point that indicates a good agreement with the typical axially symmetric limits. The results of the calculated energy levels were in acceptable agreement with the experimental data. There is no pure vibrational property of these isotones which is clearly shown in the behavior of potential energy surfaces.

Spray pyrolysis was used in this work to create un-doped ZnO and Sn-doped films with varying mass fractions (2, 4, 6, and 8wt.%) of doping on a glass substrate. The effect of Sn doping on the optical and structural characteristics of the produced thin films was investigated. All of the films were polycrystalline and possessed a structure of hexagonal wurtzite with a preference for orientation along the (002) plane, according to XRD investigations. The peak intensity (002) for 6 wt% is higher than all of the chosen doping ratios. Except for the 8% that was (21) nm, the grain size (D) increased from (22-26) nm as the percentage of Sn doping increased. In order to evaluate the optical characteristics, the absorption and transmittance spectra were recorded in different wavelength ranges of 380-900 nm. This shows that, compared to the un-doped film, the absorbance decreases as the amount of doped tin increases. When the doping ratio ranged from (0 - 8) wt%, the optical energy gap was (3.23-3.59) eV. The transmittance increases with the percentage of Sn doping, reaching its maximum value (72%) at (8%) doping.

Using shell-model calculations, the nuclear structure (energy levels and reduced transition probability) of 27Mg isotope has been studied. Shell-model codes, Oxbash for Windows operating system, were utilized to calculate the outcomes. Using a harmonic oscillator, the wave functions of radial single-particle matrix elements have been calculated. The calculated energy levels and available experimental data up to 5 MeV for 27Mg are compared. Core-polarization effects on reduced transition probability are introduced via first-order perturbation theory, which permits higher energy configurations via nucleon excitations from core orbits to those outside model space up to 9ℏω. The core-polarization effects have improved the agreement between B(E2) and their corresponding experimental data, but have no effect on B(M1), B(M2), and B(E1).

The natural radioactivity of the earth formations of Tar Al-Najaf region in Al-Najaf Al-Ashraf governorate has been studied , which is considered one of the most important archaeological areas in the province. As Tar Al-Najaf is one of the natural phenomena prominently present in the governorate, as it cuts sharply to form a rocky cliff, as well as overlooks from the southern end of a plateau Al-Najaf and on the sea of Al-Najaf, in a clear and surprising way, Al-Najaf flew, by selecting 30 sites to take soil samples from the region, and spectral measurements were made using gamma-ray spectroscopy (NaI(Tl)) . It was found that the specific activity of 238U, 232Th and 40K in the studied ranged between to with average , to (8.356±1.013) with average (21.728) and (475.391 ± 7.870) to (95.173 ± 1.994) with average (281.197) respectively. As per radium equivalent, it was between ( ) to (37.576) with average (68.678) , and the activity concentration index ranged between (0.756) to (0.272) with average (0.510) ) , while the external hazard index ranged from (0.272) to (0.101) , with rate (0.184) .

In this work, The energy levels and lowered electric quadruple transition probability B(E2) were calculated with the use of the OXBASH code in the F7shell and the F7MBZ& F742 effective interaction for the 42-43Ti isotopes. All nucleon combinations in the) 0 7/2, 1 3/2, 0 5/2, and 1 1/2 ( orbits are included in the model space. Additionally, the shell model does a good in describing the invading states' energies. Computations have been done using effective interactions F7MBZ and F742 in full f7 space, As well as the shell model, Lowlying states, and binding energies computed, and it was found that the calculated rates of electric quadrupole transitions between the isotopes 42-43Ti were consistent with the existing experimental published data.

In the current work, we focused on the impact of Indium oxide partial substitution at the (Hg) site on the structural characteristics of the (HgBa2Ca2Cu2.85La0.15O8+δ) compound with (0,0.05,0.1,0.15,0.2 and 0.25). Samples were prepared by the (SSR) method. The combined powder was crushed with a pressure of 7 tons per square centimeter to create a disc with a thickness of (0.2 cm) and a diameter of (1.5 cm). The samples sintered for 24 hours at a rate that was changed from ambient temperature to 820 °C. For the samples which were doped with (In=0.05) in comparison to other samples, the highest value of the c-axis lattice parameter and a pseudo-tetragonal structure were discovered using (XRD) analysis. It was discovered that altering the In concentrations in all of the results of our sample changes the volume fraction VPh(1223), mass density dm, and c/a. It was also determined that the change in lattice parameters, degree of crystallinity, crystal size, and strain (in different ways) resulted from a change in the indium oxide concentrations for all samples.
