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

A Comprehensive Study on Gamma Rays and Fast Neutron Sensing Properties of GAGOC and CMO Scintillators for Shielding Radiation Applications

The WinXCom program has been used to calculate the mass attenuation coefficients (μm), effective atomic numbers (Zeff), effective electron densities (Nel), half-value layer (HVL), and mean free path (MFP) in the energy range 1 keV–100 GeV for Gd3Al2Ga3O12Ce (GAGOC) and CaMoO4 (CMO) scintillator materials. The geometrical progression (G-P) method has been used to compute the exposure buildup factors (EBF) and gamma ray energy absorption (EABF) in the photon energy range 0.015–15 MeV and up to a 40 penetration depth (mfp). In addition, the values of the removal cross section for a fast neutron ∑R have been calculated. The computed data observes that GAGOC showed excellent γ-rays and neutrons sensing a response in the broad energy range. This work could be useful for nuclear radiation sensors, detectors, nuclear medicine applications (medical imaging and mammography), nuclear engineering, and space technology
