Noorzaei et. al. [3], studied on the application and verification of a two-dimensional developed finite element code for the thermal-structural and stress analysis of RCC dams.
Fig. 3: Temperature Distribution Fig.4 (a) shows the variation of maximum principle stress path along the block width (EL.3.9 m) for different construction time.
Fig.4 (a): Variation of Maximum Principle Stress path along the Dam width(EL.3.9 m) The variation of minimum principle stress along the dam width for the same level (EL. 3.9 m), has been plotted in Fig.4(b).
Fig.4 (b) Variation of Minimum Principle Stress path along the Dam width (EL.3.9 m) After completion of the thermal analysis, stress analysis is performed simultaneously and safety coefficient against cracking is calculated using Eq. 2.

These findings support El Jaouhari's (2020) findings that, depending on the climate and kind of building, a spatial reorganization using bioclimatic principles can cut heating and cooling needs by 20 to 40%. 2.
The approach used in this project is notable for combining the application of ASHRAE standards with the unique Moroccan climate, as compared to other studies carried out in comparable circumstances (Benhaddou et al., 2023).
By strategically placing apertures and optimizing air circulation, the average room temperature in the summer can be lowered by 2 to 3°C (Cohen et al., 2021)
● A 42% increase in air renewal results in improved indoor air quality, lowering CO₂ concentrations and raising occupant productivity (Balmer et al., 2020).

The DSC curves of Ti-Al-C, Al-V2O5 and
Ti-Al-C-V2O5 systems
The differential scanning calorimeter (DSC) curves of Ti-Al-C, Al-V2O5 and Ti-Al-C-V2O5 systems obtained from room temperature to 1200 °C with a constant rate of 10 °C are shown in Fig. 1.
The second exothermic peaks were wide and small in height in Al-V2O5 and Ti-Al-C-V2O5 systems.
But the peak temperature in Ti-Al-C-V2O5 shifted from 796.9 °C in Al-V2O5 to 923 °C.
Although Al almost disappeared, Ti was still existed.
