According to Luque et al 2016 biofuels produced are four times faster decomposed than fossil oil, making it more effective in reducing air pollution.
Okamoto et al. (1998) stated that the surface area of alumina is a very decisive parameter in the dispersion of Mo oxides, ie the dispersion of Mo becomes higher when the surface area of alumina gets larger.
NiMo/γ-Al2O3 catalyst has an excellent ability for deoxygenation and hydrogenation reactions (Liu, et al. 2009).

Afterward, Duflou et al. [6] introduced the hot incremental forming of Ti6Al4V, heating the working material by means of a Laser source.
Fan et al. [7] found out a cheaper solution for the hot incremental sheet forming (Hot-ISF) of Titanium sheets.
The same technique was implemented in 2012 also by Ambrogio et al. in a subsequent study [8] aimed at determining the Titanium Ti6Al4V formability by Hot-ISF for changing process conditions.
Finally, in 2013 Ambrogio et al. [10] proposed a novel experimental approach used for manufacturing Titanium sheets by ISF at high speed.

Ahn et al. [8] investigated the effect of nano-structured surfaces on a horizontal heater surface coated with MWCNTs.
McHale et al. [10] investigated the boiling heat transfer of MWCNT structures using HFE-7300 and DI water.
Recently, Shenoy et al. [11] conducted an experimental study on the MWNT structures in a minichannel with water as the cooling medium.
The wall temperature readings and boiling curves for different CNT structures and smooth Al surface with G = 50 kg/m2·s are presented in Fig. 3.

Sayyed et al. [11] studied MHD slip flow in porous space by DTM-Padé technique.
Jafarimoghaddam et al.[12] analytically solved the MHD wedge flow of nanofluids by Lambert W-function and Homotopy perturbation methods.
For β=1.5, M=2, Ω=0.5, λ=–0.5and fw=–1.5, the values of constants by LSM are and (28) In tables 1 and 2, the comparison of skin fricrtion coefficient fηη(0) by OHAM and the corresponding results of Sayyad et al.[11] and kudenatti et al.[22, 24] is made for different values of β, Ω, fw, λ and M.

Hamadache et al. [7] and Laoufi [8] have also reported that the thermal conductivity of mortars decreases with age and with the amount of cement replaced par pozzolan; this is due to the reduction in density and the increase in air content.
According to Ghrici et al. [17], the capillary pores are reduced by the formation of secondary C-S-H gel due to the pozzolanic reaction.
In addition, Siad et al. [18] reported that the significantly lower sorptivity of the SCC mixtures with Pozzolan from a natural source in Algeria or fly ash may be attributed to their less porous interfacial zone, and also the refined pore structure of the paste matrix.
These results are in agreement with those of Hamadache et al. [7, 20] and Laoufi [8].
These results are consistent with those reported by Benosman et al. [22] and Gouasmi et al. [23].
