The experimental measurement of tensile strength on individual chemical components of cement paste was for the first time performed by Němeček et al. [1] on micro-beams with triangular cross sections created by Focused Ion Beam technology (FIB).
These values were compared to Němeček et al. [1], where the mean tensile strength for inner product was found ca. 700 MPa which gives a good agreement.
Molecular dynamics models using bottom-up approach estimated fracture energy as 1.72 ± 0.29 J/m2 in Bauchy el al. [10].
Němeček et al. [1] found previously supremum fracture energy of the inner product as 19.7 ± 3.8 J/m2 which give a good agreement with the current results.

Wang et al[4] used VIDAS image analytical system (2.1c; Zeiss Company, Germany) to reconstruct three-dimensional images.
Chen et al[5] reconstructed the three-dimensional image by using CT scanning and simulated the surgical processing.
Effect of prosthetic replacement on interface stress Nygaard et al[14] thought that when prosthesis was implanted into pulp cavity, the interface between bone and prosthesis could afford compression loading; otherwise, if tangent movement was induced on the interface between bone and prosthesis, bone tissue could be absorbed.

According to Som et.al (2008) who found similar trend of results noted out that the high intensity bands located at around 585 nm is due to their hypersensitive pseudo-quadrupole transition characteristics, which is the main determining factor for the value of the Judd-Ofelts parameter, [14].
In the recent works by N.Elkhoshkhany et. al (2014) found that optical band gap are ranging from 3.16eV to 3.34eV for the lithium borotellurite glass system [15].
According to Amjad et.al (2012), index of refraction is depends on the electron density or the polarizability of ions to a large extent [18].
As noticed by Amjad et.al (2012) in their works found the relation between refractive index and the polarizability.

Introduction
Bulk amorphous alloys with a wide supercooled liquid region in a number of alloy
systems, including Mg-TM-Ln, Ln-Al-TM, (Zr, Hf)-Al-TM (TM = Fe, Co, Ni, and Cu) and
Zr-Al-Cu-Ni, has been prepared successfully by Inoue and his coworkers[1-3].
Inoue et al.[16] suggested that large atomic size ratios, attractive bonding nature between the constituent elements, and the difficulty of redistributing these elements for crystallization are dominant factors for the increase in glass-forming ability and the appearance of a wide supercooled liquid region.

Its structure is composed of hexagonal nets of
Al separated by layers of edge-sharing Ti3C2 layers.
Experimental Procedure Polycrystalline Ti3AlC2 was synthesized from TiCx (x=0.6) and Al (<45 μmφ, 99.7% purity) powders.
Starting powders were weighed in the molar ratio of TiCx : Al = 3 : 1.1 using a microbalance, mixed in a SPEX shaker mill apparatus for 10 min., and hot pressed to 19 mmφ x 10 mm cylindrical specimens under 25 MPa pressure for 60 min in flowing Ar gas.
During hot pressing, reaction between TiCx and Al powders occurred to form Ti3AlC2.

Anderson et al. [1] showed the reduction in cutting force is 25% and increment of tool life between 200 to 300%.
Otherwise, Shi et al. [2] reported the plastic deformation of Inconel 718 materials was reduced due to the reduction of cutting force when the preheat temperature rise between 700 to 800 oC.
Navas el al. [3] shows that the optimum distance of 45 mm between laser spot and cutting tool in turning process has achieved the maximum reduction of cutting force and minimum tool degradation by applied overheating.
Furthermore, Dumitrescu et al. [4] revealed that the appropriate distance for AISI D2 material is 85 mm in laser assisted turning process.
