Eliminating black holes singularity in Brane world Cosmology
Poula Tadros, Mohamed Assaad Abdel-Raouf
In recent works, a construction was proposed resulting emergent universes inside black holes. This result can be obtained from a 4D black hole embedded in a 5D space time with the…
On models of Cosmology
Poula Tadros, Mohamed Assaad Abdel-Raouf
In this work the most promising string cosmology models are re-viewed model by model in detail. These models are based on conceptsform string theory and heterotic M theory to const…
Ab initio Calculations of the Interface States of Polyacetylene-Polyvinylfluoride and Polyethylene - Polyvinylfluoride Quasi-one-dimensional Chains
Mohamed Assad Abdel-Raouf
The interface states appearing in polyacetylene-polyvinylfluoride and polyethylene-polyvinylfluoride are determined via an ab initio self consistent field technique based on Green…
Inner-shell Annihilation of Positrons in Argon, Iron and Copper Atoms
M. A. Abdel-Raouf, M. M. Abdel-Mageed, S. Y. El-Bakry
The annihilation parameters of positrons with electrons in different shells of Argon, Iron and Copper atoms are calculated below the positronium (Ps) formation thresholds. Quite ac…
Possible Coexistence of Antihydrogen with Hydrogen, Deuterium and Tritium Atoms
Mohamed Assad Abdel-Raouf
Recent productions of large numbers of cold antiprotons as well as the formation of antihydrogens at CERN and Fermilab have raised basic questions about possible coexistence of mat…
Emission of K -, L - and M - Auger Electrons from Cu Atoms
Mohamed Assad Abdel-Raouf
The emission of Auger electrons from the K-, L- and M-sheels of two configurations of copper atoms is investigated in detail within the frame work of the momentum average technique…
