In this research, the effect of the first order magnetic field on the ground-state of a centered hydrogenic donor impurity in a GaAs/AlAs spherical quantum dot has been calculated. The perturbation method has been used within the framework of effective mass approximation for these calculations. Overall, the analysis shows that a proper choice of quantum dot radius and magnetic field can signifi...

We investigate known security flaws in the context of security ceremonies to gain an understanding of the ceremony analysis process. The term security ceremonies is used to describe a system of protocols and humans which interact for a specific purpose. Security ceremonies and ceremony analysis is an area of research in its infancy, and we explore the basic principles involved to better underst...

Transition rates, oscillator strengths, and line strengths are calculated for the 49 possible electric-dipole transitions between the eight even-parity 2s2p states and the seven odd-parity 2s2p and 2p states in boronlike ions with nuclear charges ranging from Z56 to 100. Relativistic many-body perturbation theory ~MBPT!, including the Breit interaction, is used to evaluate retarded E1 matrix el...

rangelands are known as one of the main income resources for their exploiters.in the recent century, management of iran rangeland has undergone vast transformationsbecause of vulnerable socio-economic conditions of pastoralists. a study was done toprovide a clear picture of the status and utilization of aq qala rangelands via assessinginternal and external environmental factors affecting the ut...
