Z. Salmand@d.com<p>This work concerns with the investment of solar power to run water coolers . Four water coolers with 20 liters operational capacity are used for eight hours. It was a design calculations required to set up a full solar system. And have been performed calculations design in two stages to get the desired results, the first theoretical and that on the basis of which require the construction of the solar system, solar panels number six with a capacity of 100 watts and four inverters capacity of 1000 watts with 12 volts as parts mainly effective with the controllers of charging and battery with container number four In order to run the system. But that did not happen and did not operate the system, only third hour later got a hard landing.The second is experimental design process and that on the basis of which require the construction of the solar system solar panels are eight with capacity of 100 Watts and four inverters capacity of 1000 watts with 24 volts as parts effective principally with the controllers of charging and battery container with the number four, which gave the functioning effectively for eight hours and achieve the desired results of this research, which it installed on the surface of renewable energies technology center in University of Technology. In order to discuss the main factors affecting the solar panels the following parameters should be measured such as the output power, the ability of output flow and the surface temperature, and the efficiency of photoelectric conversion and working hour. Where the measuring devices are available in the lab of energy and renewable energies technology centre in University of Technology .</p>http://www.iiste.org/Journals/index.php/APTA/article/view/36335Evaluation of Excess Lifetime Cancer Risk from Gamma Dose Rates in Coastal Areas of Bonny Island, Rivers State, Nigeria2017-04-30T13:12:33+00:00Chinyere P. Ononugbod@d.comAtisi A. Bubud@d.com<p>The study assesses the excess lifetime cancer risk from gamma dose rates measured in coastal areas of Bonny Island, Rivers state, Nigeria. An in-situ measurement of radiation exposure rate was done using well calibrated radiation meter (Digilert-100). The exposure rate ranges between 12.0 and 18.6 µRh<sup>-1</sup> with an arithmetic mean of 14.47 µRh<sup>-1 </sup>. The absorbed dose rates ranges between 86.6 and 161.8 nGyh<sup>-1</sup> with an arithmetic mean value of 137.5 nGyh<sup>-1</sup>. This value is higher than the population weighted world average value of 60.0 nGyh<sup>-1</sup>.<sup> </sup>Inhabitant of Bonny Island are subjected to an external effective dose ranging between 133.22 to 248.04 µSvy<sup>-1</sup> with an arithmetic mean value of 192.93 µSvy<sup>-1</sup>. The excess lifetime cancer risk estimated from the effective dose ranges from 0.47 x 10<sup>-3</sup> to 0.87 x 10<sup>-3</sup>with an arithmetic mean of 0.67× 10<sup>-3</sup>. The background radiation of Bonny Island has been enhanced due to oil and gas exploitation activities in the area<em>. </em></p> <p><strong>Keywords: </strong>Radioactive materials, excess lifetime cancer risk, gamma dose rate, Bonny, Digilert-100.</p>http://www.iiste.org/Journals/index.php/APTA/article/view/36336Applications of Hellmann-Feynman Theorem (HFT) to Angle Dependent Yukawa Potential of Diatomic Molecules2017-04-30T13:12:33+00:00Akaninyene D.

It was obtained a various new solutions by applying this method and including solitons, kinks and plane periodic solutions. More importantly, for some equations, we also obtain other new and more general solutions at the same time. It is shown that the extended tanh method is straightforward and concise, and more powerful mathematical tool can be applied to other nonlinear partial differential equations arising in mathematical physics problems.</p> <p><strong>Keywords:</strong> Extended tanh method, nonlinear generalized Ito system.</p>http://www.iiste.org/Journals/index.php/APTA/article/view/36338Time’s Bang Theory2017-04-30T13:12:33+00:00Ahmed Alsayedd@d.com<p>Pre Big Bang phase remains a key to get perfect time’s origin and to determine its creative role, so the aim of this study is to confide time’s mechanism in the universes evolves processes.</p> <p>Calculations based on Quran data – fourteen centuries ago – of universes evolves phases are the access to have a due theory:</p> <p>Pre Big Bang evolves period = 91,736,492,148,000 m/s</p> <p>Big Bang evolves period = 122,315,322,864,000 m/s.</p> <p>Time occurs in two types; compact at pre Big Bang phase where it begins and multitude at Big Bang phase.

Additionally, it is debated that a more sophisticated theory beyond the quantum theory emerges as a need for a better understanding of the atomic and sub atomic worlds. This paper, for that reason, focuses on the very fundamental structure of the quantum theory such as the physical and philosophical meanings of the wave functions, the probability and the Schrödinger Wave Equation (SWE). Specifically deals with the time evolution of the free quantum particles. The work just arises from the difference of the classical and quantum waves, specifically the comparison of the time and space dependence of classical waves and Schrödinger waves, for the free space, indicates that time dependence shows a clear dissimilarity. In order to tackle the problem, a time dependent momentum operator, for the first time, is defined and consequently an alternative TDSWE is straightforwardly derived and its philosophical implications have been discussed. Additionally, time and position dependence of the probability functions, relating free particles, have been physically and philosophically discussed and some alternative approaches and comments are forwarded. Finally, the approaches, comments and mathematical equations are in good agreement with the standard quantum theory and interestingly go further possibly tracing some signs of new pathways to resolve the mysterious quantum world.</p> <p><strong>Keywords: </strong>Schrödinger wave equation, fundamentals of quantum mechanics, momentum operator, quantum probabilities, time evolution of quantum systems.</p>
