Characterization of Thermal Inertia and Footprint Carbon of Clay-Wool, Clay-Cork, and Clay-Plastic Composites Soumia Mounir1,a*, Youssef Maaloufa2,b, Khabbazi Abdelhamid3,c and Khalid El Harrouni4,d 1National School of Architecture Fez, road of Sidi Hrazem, Parc Fez shore, FEZ Morocco. 2National School of Architecture Agadir, Complex Ibn zohr, street Dakhla BP 20732, Agadir Morocco. 3EMDD, EST Salé, University Mohamed V, Avenue prince Heritier, BP11060, Salé Morocco. 4National School of Architecture Rabat, Avenue Allal el Fassi, Madinat al Irfane, BP 6372, Rabat, Morocco.
Mounir and al [4] have studied the thermal characterization of the composite clay-cork for the different volume fraction of cork using the methods hot plate in the transient, and steady-state regime and Flash.
Mounir and al.[5] have studied the composite clay-wool which presents important characteristics in terms of thermal properties especially thermal conductivity which is 0.19 W.m-1.K-1 for the highest volume fraction of wool (y=0.124).
Afshin afshiari and al [7] revealed that a consensus was forming among experts to achieve emissions reductions at a lower cost by integrating the energy efficiency concepts.

This work has the aim to obtain and to characterize molecular sieves type MCM-41 and Al-MCM-41 using new routes of synthesis.
Al-MCM-41 - This material was prepared following the procedure reported in the literature [11].
Structural properties of the samples – XRD analysis Samples 2q d100 a0 MCM-41 2,25 39,10 Å 45,15 Å Al-MCM-41 2,26 41,68 Å 48,13 Å The molecular sieve Al-MCM-41 presented a higher network parameter compared with the MCM-41.
Fig. 5 Diffractogram of MCM-41 Fig. 6 Diffractogram of Al-MCM-41 Conclusions According to XRD results it was possible to see that the RHA, after treatment, proved to be an adequate source of silica for the production of molecular sieves MCM-41 and Al-MCM-41.

Experimental Superalloys on the basis of Ni-Al alloyed by refractory elements were the object of the study.
The alloy composition was chosen so that the ratio of Ni and Al in the sum with the other elements replacing the sites of the Al in the L12 superstructure was 0.77 / 0.23.

As it was shown earlier [5] for cubical crystals, the electronic (high-frequency) dielectric susceptibility is given by the expression       α−αα+ α γ=χ )51( 16 9 1 12 2 22 2 232 2 1 p cm c el V d�e , (2) where 2V is the covalent energy [1,2], 3 )2/33( − = d � is the valence electron density, which permits us to calculate the corresponding dielectric constant el 141 πχ+=ε∞ .

Agostini et al. [2] proposed a solution of two-phase thermosyphon loop for the cooling of power-electronic semiconductor modules.
The heat transfer characteristics of two-phase flow inside minichannels were done using the latest correlations available in literature like for example: the El-Hajal et al. [15] correlation for void fraction, the Zhang-Webb [32] correlation for the friction pressure drop of two-phase flow in adiabatic regions, the Tran et al. [30] correlation for the friction pressure drop of two-phase flow in heated regions, the Cavallini et al. [12] correlation for the friction pressure drop of two-phase flow in cooled regions.
In addition, the following correlations were also used in calculations: the Mikielewicz et al. [23], Saitoh et al. [27] and Owhaib [26] correlations for the flow boiling heat transfer coefficient in minichannels and Mikielewicz et al. [23], the Shah [28] and the Tang et al. [29] correlation for the flow condensation heat transfer coefficient in minichannels.
The El-Hajal‘s [15] empirical correlation for the void fraction in two-phase separate flow model was applied in calculations.
