Umorend@d.comAkaninyene D. Antiad@d.comAkaninyene O. Akankpod@d.comCyril C. Umorend@d.com<p>In this paper, the energy and momentum of the Armenians Special Relativity Theory (ASRT) and Special Relativity Theory (SRT) are obtained and their comparison is also carried out. SRT through the Muhelson-Morlay experiment proved that aether does not exist in space, but ASRT reincarnates the aether as a universal reference medium. The mathematical existence of aether has already been proven. In his work, by comparing energy and momentum of both SRT and ASRT, the results obtained indicate that difference is in the time-space or subatomic aether medium which is represented by space coefficient and geometrical space . The theory brings together followers of absolute aether theory, relativistic aether theory and the dark matter theory. The energy and momentum in SRT can be deduced from ASRT by substituting and . This implies that, SRT is a limiting case of ASRT.</p> <p><strong>Keywords</strong>: Relativistic theory, Rest Particle, Dark Energy, Armenian Theory</p>http://www.iiste.org/Journals/index.php/APTA/article/view/39061Heat and Mass Transfer in Radiative Casson Fluid Flow Caused by a Vertical Plate with Variable Magnetic Field Effect2017-11-01T12:22:20+00:00R. Vijayaragavan S. Karthikeyand@d.com<p>The aim of the present study is to investigate influence of variable magnetic field, heat and mass transfer in radiative Casson fluid flow past an infinite vertical porous plate. The governing equations of the flow, heat and mass transfer are transformed into a system of nonlinear ordinary differential equations and solved analytically by the perturbation technique with matlab package. The results obtained show that the velocity, temperature and concentration fields are appreciably influenced by the chemical reaction, thermal stratification and magnetic field. It is observed that the thermal radiation and magnetic field decreases the velocity, temperature and concentration profiles. There is also considerable effects of magnetic field and chemical reaction on skin friction coefficient and Nusselt number.</p> <p><strong>Keywords: </strong>MHD, Variable magnetic field, Radiative, Casson fluid, dissipative, Heat transfer, Mass transfer.</p>http://www.iiste.org/Journals/index.php/APTA/article/view/39062Simulation of Cross Section for the Production of Copper-642017-11-01T12:22:20+00:00George Eduseid@d.comAba Bentil.

Tandohd@d.com<p>The radionuclide <sup>64</sup>Cu (T<sub>1/2 </sub>= 12.7 h) is an important positron emitter, suitable for combining PET imaging and therapy. We evaluated four reactions, namely <sup>64</sup>Ni( p, n)<sup>64</sup>Cu, <sup>64</sup>Ni(d, 2n)<sup>64</sup>Cu, <sup>68</sup>Zn( p, αn)<sup>64</sup>Cu and <sup>64</sup>Zn(d, 2 p)<sup>64</sup>Cu. Data analysis was generally limited up to about 30MeV using the nuclear model code TALYS-1.6. The result compared favourably with experimental as well as other theoretical works in literature. The integral yields calculated from those data are also given. A critical comparison of the various production routes of <sup>64</sup>Cu is presented. The <sup>64</sup>Ni (p, n)<sup> 64</sup>Cu reaction, utilizing a highly enriched target, is the method of choice.</p> <p><strong>Keywords:</strong> <sup>6464</sup>Cu Production, Excitation Functions, Calculate Thick Target Yield</p>
