Mistranslations of the Prophets' Names in the Holy Quran: A Critical Evaluation of Two Translations

This study is devoted to discuss the renditions of the prophets' names in the Holy Quran due to the authority of the religious text where they reappear, the significance of the figures who carry them, the fact that they exist in many languages, and the fact that the Holy Quran addresses all mankind. The data are drawn from two translations of the Holy Quran by Ali (1964), and Al-Hilali and Khan (1993). It examines the renditions of the twenty five prophets' names with reference to translation strategies in this respect, showing that Ali confused the conveyance of six names whereas Al-Hilali and Khan confused the conveyance of four names. Discussion has been raised thereupon to present the correct rendition according to English dictionaries and encyclopedias in addition to versions of the Bible which add a historical perspective to the study. Keywords: Mistranslation, Prophets, Religious, Al-Hilali, Khan

Evaluation of High Impedance Surfaces for MRI RF Coil Applications ­ Simulations of RF Field and Specific Absorption Rate

This paper investigates the use of High Impedance Surfaces (HIS) to enhance the magnetic near-field within a dielectric phantom stimulated by a surface coil antenna resonating at 63.8 MHz for use in Magnetic Resonance Imaging (MRI) systems. Specifically, the optimization of the space between the surface of the coil and the HIS is presented here. The HIS incorporates interdigitated capacitive elements that produce an electrically small unit cell size. The magnetic field strength is shown to be improved by 42% as compared to a system which uses only an RF shield The associated Specific Absorption Rate (SAR) for the optimum design is simulated and compared to international standards. The work is aimed at 1.5T MRI applications

Using of Chroococcus SP. to Treat Polluted Water with Cadmium & Nickel

Chroococcus sp. was exposed to different concentrations 0.3, 0.5, 1, 2, 3, 4, 5, 6 and 7 ppm, from cadmium and nickel. The results revealed that the ability of the alga to remove cadmium and nickel was increased with the increase of the metal concentration which the alga exposed to them and this case does not record before. This may relate to mechanisms of adsorption and removal which not understood perfectly till now according to many researches that concerned with this field of studies. It was noticed that the removal percentage of cadmium reaches to 77.66 & 76% in the two higher concentrations 6 & 7 ppm, which exposed to the alga till the last day (twelve days) from the experiment, but same percentage (77.66 & 76%) was recorded on the eighth day of the experiment to remove nickel and decrease to 12.5 & 28% on the last day of the experiment for the above two concentrations
