ION-IMPLANTED GLASS WAVEGUIDES: A REVIEW

Shu Cheng — 2013-05-20

Physics International, Published online: 20 May 2013; doi:10.3844/pisp.2013.1.12

As a well-known technique for material modification, ion implantation has become an effective method to fabricate waveguide in optical glasses. The guiding structures can be accurately controlled by t...

THE THEORETICAL SIMULATION OF AXIAL VIBRATIONS IN FINITE CYLINDRICAL PIEZOELECTRIC SHELL MADE OF THE TRIGONAL (3M) CRYSTAL

H. Zeynali — 2013-02-15

Physics International, Published online: 15 February 2013; doi:10.3844/pisp.2013.13.22

The axial vibration in a thin layer of finite cylinder made of trigonal (3M) piezoelectric crystal are investigated. By using a closed form solution of the equations of motion and applying new boundar...

ON THE BLOW-UP BEHAVIOR OF SOLUTIONS TO A SYSTEM WITH FRACTIONAL POWER

Ali Hakem — 2013-06-28

Physics International, Published online: 28 June 2013; doi:10.3844/pisp.2013.23.28

The aim of this research is to study the nonexistence of global weak solutions for systems of fractional power. The method relies on a suitable choice of test function.

ACCELERATION AND PARTICLE FIELD INTERACTIONS OF COSMIC RAYS II: CALCULATIONS

A. Tawfik — 2013-07-17

Physics International, Published online: 17 July 2013; doi:10.3844/pisp.2013.29.36

The Ultra High Energy Cosmic Rays (UHECRs) is still a one of the most controversial physical problems, especially that all potential acceleration mechanisms are not entirely able to explain the source...

THE PROPERTIES OF NUCLEAR MATTER

Khaled Hassaneen — 2013-07-17

Physics International, Published online: 17 July 2013; doi:10.3844/pisp.2013.37.59

The microscopic and bulk properties of nuclear matter at zero and finite temperatures are studied in the frame of the Brueckner theory. The results for the symmetry energy are also obtai...

DYNAMICAL 3-SPACE: NEO-LORENTZ RELATIVITY

Reginald Thomas Cahill — 2013-07-17

Physics International, Published online: 17 July 2013; doi:10.3844/pisp.2013.60.72

The major extant relativity theories-Galileo’s Relativity (GaR), Lorentz’s Relativity (LR) and Einstein’s Special Relativity (SR), with the latter much celebrated, while the LR is essentially ig...

THE STRUCTURE AND MECHANICAL PROPERTIES OF ALUMINA FILM PREPARED BY RF DIODE SPUTTERING

H. Panitchakan — 2013-07-17

Physics International, Published online: 17 July 2013; doi:10.3844/pisp.2013.73.80

Alumina (Al2O3) films were prepared on Al2O3-TiC substrates by RF diode sputtering. The target sputtering power was varied from 4 to 8 kW. The effects of target sputtering power on the structure and m...
