Other researchers (Nataraj and McManis, 1997; Al Wahab and El-Kedrah, 1995; Puppala et al., 2006; Miller and Rifai, 2004; Ozkul et al., 2007; Kumar Tabor, 2003) also reported similar results.
In contrast, other researcher such as Ozkul et al, 2007 reported not significant changes on compaction parameter by fiber inclusion.

There were many kinds of metal elements in food residue including Al, Fe, Mg, Zn, Pb, Cr, Cd, etc.[17, 18] By pre-analysis we found that the amount of heavy metals such as Pb, Cr and Cd was very little, so we chose Al, Fe, Mg and Zn as parameters for food residue to determine the metal content.
The content of Al for each type of catering habits was under 4 mg/kg, except seafood restaurants.
Seafood restaurants got Al content of 9.62 mg/kg, much higher than the others.

Effects of Cu Addition on Age Hardening Response of Al-7Si-4Mg Alloys at 130 oC aInas M.
For that, Al alloys are option to be the constituent material [2].
According to Syahid, et al. [4], hardness of Al-7Si-4Mg alloys increased as the content of Cu was greater.
It means that Cu does not play a significant role in precipitation process as also found in Syahid, et al. [4] and Zulfia et al. [9].

In [2], Haji et al. studied heat conduction in composites materials in finite dimensions by using Green's function.
For calculation of the effective thermal conductivity, we obtain by using the linear relation above (Eq. 24) km= 252 W.m-2.K -1, and by using Kanan et al model [11], km= 224 W.m2.K -1.

Horz et al comprehensive studied the mesh bumpers[3-5].
A 3.97mm-diameter aluminium-alloy(AL 2017-T4) sphere was used as projectiles in the experiments.
The multi-layers aluminium-alloy(AL 5A06) meshes were used as the first layer bumper.

(4) Driver et al [13] also considered the interaction, proposed the Eq.5 of shear strength of trapezoidal corrugated webs for the design in bridge girders:
We could take the Eq.6 provided by Elgaaly et al. to describe the inelastic shear buckling stress [14] when the elastic shear buckling stress exceeds 80% of the shear yield stress.
To consider of a smooth transition between the local elastic buckling strength, the global elastic buckling strength, and the yield strength, El-Metwally [15] provides the Eq.7 for the shear strength, then suggests using n=2 for trapezoidal corrugations
Jiho Moon et al [20] made the theoretical and finite element analysis of the lateral-torsional buckling of H-beam with corrugated web under uniform bending.
Ahmed salah El-Metwally is one of the earlist scholar who put forward this structure [24].

Al-Qureshi´s [2] Mf equation is based on elastic ideally plastic material model without work hardening.
El Megharbel [3] has reflected Al-Qureshi´s theoretical approach and assumptions, nevertheless he introduce work hardening material model.
