Abstract

My purpose consisted in creation of a new relativistic space-time theory instead of Einstein’s Relativity Theory, but basing upon only one postulate. This could become feasible only if a law of light propagation in a moving inertial reference frame could be made a consequence of the relativity postulate. It was made a reality by P.M. Rapier’s discovery of a quadratic dependence of the light speed upon the light source speed. Considering various ways of making the second postulate superfluous the most short of them was through introducing into the theory of a new concept “light speed in a moving inertial reference frame” by means of usage of the known four-dimensional Minkovski’s formalism. This new light speed was defined as equal to a fourth component of a four-dimensional speed of any moving particle. Then using this newly introduced concept the time-measurement unit was calculated for a moving light clock that occurred to be equal to the time measurement unit of a stationary light clock. And as a very happy event the time dilation effect was deleted from the theory.

Abstract

Building materials are one of the potential sources of indoor radioactivity because of the naturally occurring radionuclides in them. Radon exhalation rate is one of the most important factors for evaluation of the environmental radon level. Radon contributes more than half of the total ionizing radiation dose Indoor radon has been recognized as one of the health hazards for mankind because long-term exposure to radon increases the risk of developing lung cancer. This study aims at assessing the contribution of destroyed building materials in war 2014 towards the total indoor radon exposure to the inhabitants of in . 40 Samples have been collected from common destroyed building materials in Jabalia district. The closed-can technique has been employed in this study using solid state nuclear track detectors (CR-39). After 124 days of exposure to radon, CR-39 detectors were etched chemically by (6 N) NaOH solution at 75°C for three months and then counted under an optical microscope. Results obtained from the current study show that radon exhalation rates from concrete and asbestos have relatively high values as compared to other building materials while glass, marble and a red brick contribute less to radon exhalation rate. The average radon exhalation rate in term of area in the studied samples ranged from (86.506) mBq.m-2.h-1 for glass samples to (469.017) mBq.m-2.h-1 for Concrete samples. In general, the annual effective doses from the investigated building materials are low and under the global value (from 1 to 5 mSv/y) except for Concrete and asbestos samples with average values (9.464) and (9.3528) mSv/y, respectively.

Abstract

A theoretical study of InSb based on the effect of van der Waal’s interactions (VDWI) and three-body interactions (TBI) into the rigid shell model (RSM) of zinc blende structure (ZBS). The van der Waal’s three body shell model (VTSM) is performed to analyze the phonon dispersion curves, Debye temperatures variation, combined density of states (CDS) curves, two-phonon Raman and anharmonic elastic properties, where the short range interactions are operative upto the second neighbours. Our results are reasonably good agreement observed between theoretical and experimental data.
