Morel et al. compared a concrete house and a rammed earth house, demonstrating that the impact of transportation decreases by up 453% and the energy embodied in a building by 240% (Morel et al., 2001).
Little research about the use of sheep wool for earth construction is available, mainly about CEB production (Aymerich et al., 2012; Galán-Marín et al., 2010).
The humidity in the sample can strongly influence the final compressive strength by modifying the suction properties of the material (Champiré et al., 2016; Chauhan et al., 2019).
As an example, (Statuto et al., 2018) et al. found that the use of wool fibers at 3% in the mixture for adobe bricks double the maximum compressive strength against control samples and Galán-Marín et al., 2010 showed increments in the compressive strength of 37% (from 2.32 to 3.05 MPa), using wool fiber (0.25%).

Ranjan et al. studied the chemical system SrTiO3 - CaTiO3 and reported similar distortions [40].

Moreno et al. state that discussions concerning the relationship between design and the environment emerged in the 1970s [12].

However, for all the nc and UFG metals studied so far, the ductility (elongation to failure observed in uniaxial tension, %EL) is severely reduced compared with that at conventional grain sizes (typically many microns) [3].
An effort to improve m was recently reported by Valiev et al. [36], who showed that by using 16 ECAP passes, the grain size in bulk Cu can be refined down to 100 nm.

In this study, the cell shape was changed to a spheroid form after the mono layer had been formed by the close cell contact [25], and this result is in agreement with that observed by Hunter et al [36].
Owen et al. classified the progress of cell differentiation into 3 stages in their study on the differentiation of the osteoblast cells in Sprague-Dawley rats [37].
Gerstenfeld et al. [40] and Siffert [41] reported that alkaline phosphatase activity is associated with the maturation of the matrix, but its major role is cell metabolism before bone formation.
According to the reports by El-Ghanuam et al. [42] and Itakura et al. [43] the activity exhibited the maximum at the 10th day, while gradually increased until the 31 st day according to Quarles et al. [33] Although the results in this study could not be compared directly with those of previous reports, it should be observed that a greater amount of bone nodule was formed in the experimental group compared to that in the control group.

Deshayes et al. [7] have carried out a FEM comparison study dealing with the cutting of (AISI) 4340 steel alloy with AdvantEdge and Abaqus/Explicit, obtained results were qualitatively in agreement with experimental ones.
Similar simulation, with the two pre-cited software, was also performed by Arrazola et al. [6] in the case of AISI-4140 steel alloy machining.
Soriano and Lianos et al. [8] have presented a comparison of 3D machining models developed under commercially available FE software Abaqus/Explicit, AdvantEdge and Deform3D for the work material Inconel 718, Computational results obtained from the FE models treating the effect of cutting speed on part-too interaction were presented.
