Ti3Al phase is not detected in the LR samples, as Al and Ti signals are kept constant along the scanned line.
Intensity of Al and Ti of EDX measurements (left) along a horizontal line of MZ (right).

EDX spectra of the geopolymer in Fig. 2 (d), shows peaks of Na, Si, Al, and O, which shows it has had elements of standard geopolymer [6].
In addition, the ratio of Si/Al was 1.12, which is almost equal to the theoretical value for Na-poly (sialate) in which the ratio of Si/Al equal one.

Jahangirian et al. [6] studied the thermal and chemical structures of highly diluted biogas by N2 in counter-flow diffusion flames.
Galletti at el [15] illustrated that in a 300-kw chamber the rate of NOx emission decreases dramatically from 1500 ppm in conventional combustion down to 100 ppm in flameless mode by applying recuperators.
Derudi et al. [36] shows biomass gas with low calorific value should be applied under thecondition of high recirculation rate at Kv>5 and high furnace temperatures more than 8000C in flameless combustion system.
Szegö et al.[27] illustrated CO emission in very high diluted flameless mode is more than traditional flame, because in conventional mode the concentration of hydroxyl radial (OH) which controls transformation of CO into CO2 decreases.

One of the goals of the work was to obtain the activation energy for the formation of defects by performing electrical measurements on both materials (pure Al and 3003 Al alloys ). 1.

In general, this term is nonlinear and there are different methods to treat it (Guo et al. [3]).
It shows also comparative results of several other classical discretization methods for the benchmark of a cubical cavity, recently initiated by Tric et al. (2000).
Note that the (Log scale) linear evolution is due to the establishment boundary layer (see for instance Ameziani et al. [8, 9]) Fig 4.

Ravishankar et al [1]-[6] investigated a triangular pyramid solar still with and without energy storage.
Also, the use of nano fluids in the triangular pyramid solar still are arrived by Nagarajan et al [11] and R.Sathyamurthy et al. [12] R.
Sathyamurthy et al [13-15] and Arunkumar et al [16] also identified different low cost solar still.

Materials and experimental procedure Table 1 Chemical composition of tested steel wt% C Mn Si Cu Al Ni Cr P 0.027-0.07 0.14-1.433 ≦0.405 0.018-0.328 ≦0.0782 0.007-0294 0.01-0.47 ≦0.01 The tested steel was obtained from the CSP line of Wuhan Iron and Steel (Group) Corporation with chemical composition shown in Table 1. a serious rolling piece at different stands (F1-F7) was obtained by suddenly stopping the CSP line when seven-stand was just finished during its production of the steel, and specimens were cut from it after each pass of the same rolling piece.
The alloying elements mainly include C, Mn, Si, Cr, Ni, Cu, P and Al(those whose amount less than 0.01% were ignored).
Consequently,the connection of the structure and the yield strength(YS), the tensile strength(TS) and the elongtaion (EL) of Q235B can be described as follows[7]： YS=514.66+484.26[C]+55.01[Mn]+221.49[Si]+150.13[Cu]+86.64[Al]-132.21[Ni]+12.82[Cr] +206.78[P]-9553.53XFd-1/2-1.16XP (8) TS=574.38+670.43[C]+67.94[Mn]+225.48[Si]+153.41[Cu]+23.31[Al]-131.47[Ni]+70.37[Cr] +232.36[P]+389.53XFd-1/2-2537.19XP (9) EL=68.83-34.30[C]-1.62[Mn]-12.86[Si]-9.58[Cu]+5.85[Al]+6.48[Ni]+4.85[Cr]-27.11[P]-20.6 3XFd-1/2-262.41XP (10) where XF, XP are the volume fraction of ferrite and perlite,respectively; d is the size of ferrite.
