Abstract.
Walker et al. [2] have performed steady-state calculations in T-junction with ANSYS-CFX-10 using different turbulence models.
Chapuliot et al. [4] have inspected the incident of the residual heat removal system of the Civaux unit 1 reactor using the CAST3D code.
Sakowitz et al
Ayhan et al. [7] investigate the thermal mixing and fatigue damage in power plant pipes by estimating the frequency of velocity and temperature fluctuations in the mixing region using RANS and LES.

One of the important parameter, formability factor, , developed by Abdel-Rahman and El-Sheikh [3] describes the effect of mean stress and the effective stress and the influence of density on the forming limit.
Further, Narayanasamy et al. [8] explored on the instantaneous strain-hardening behavior of an aluminum-iron material.

Shuangchen Ruan, et al [8] had taken into account the incident optical field distribution of amplitude with time, light interaction with two-level atom was discussed.
Use density matrix equations and the Bloch vector model to study the transition process of two-level atomic system in the optical field of the chirped pulse, zhenxing Fu, et al [9] found that chirp effect made the system particles on the excited state occur population oscillation.

Abstract.
Pavesi et al. reported that their samples, including Si-nc’s formed by using Si-ion implantation, exhibited photoluminescence (PL) and a large optical gain of 100 cm-1 in a wavelength range from red to infrared after annealing at 1100 oC [3].
Furthermore, Orita et al. reported that integrating two-dimensional (2-D) PhCs on light-emitting diodes (LEDs) is one solution for achieving high extraction efficiencies [7].

EL quantum yield of the sample was low what can be attributed to not well-balanced transport of electrons and holes.
Indeed, external quantum efficiency of the EL diode with this modified active layer increased and reached 0.012%.

However, integrating remote sensing and GIS can be an effective tool to map the changes in a fast and effective way (El-Asmar, 2002; Hernecke, 2004).
Examples of studies to detect coast changes in China with remote sensing are from the Yellow River delta (Chang et al., 2004), and the Bohai sea (Jiang, et al., 2003).

The strain rate sensitivity of various relative densities, open-cell aluminium alloy foams fabricated by a powder metallurgical method is investigated by Yi et al. [9] under compression loading at different strain rates (10-3 to 2600s-1).
Dynamic compression of aluminium alloy 2519A at different strain rates (600−7000s−1) and temperatures (20 − 4500C) was investigated by Zhang et al. [10] and the strain rate sensitivity exponent was determined for different temperatures.
The stress–strain behaviour of the aluminium alloy AA7075 is characterized by Borvik et al. [12] in dynamic tension and compression and by El-Magd and Abouridouane [13] in tension, compression and shear.
The constituents of the material in wt.% are Al: 98.67, Mg: 0.567, Mn: 0.022, Si: 0.415, Fe: 0.148, Cu: 0.055, Ni: 0.040, Zn: 0.030, Ti: 0.003, Cr: 0.005, Pb: 0.010 and Sn: 0.025.
