Au nanoparticles with SiO2 were synthesized by a modified procedure previously reported by Li et al [15]. 0.4 APTMS solution (1mM) was mixed with the 30 ml of Au colloid then added with silica gel solution.
It is also in good agreement with previous research by Tanvi et al. [7].
According to Yu et al., the sharper the broad, the more crystalline the nanoparticle [14].
This result is similar with that reported by Wang et al. in which silicate microsheet caged TiO2 photoanode increased the efficiency by 15,36 %, while Törngren et al. reported Au@SiO2 nanostructure photoanode increased the overall efficiency by 10% [8,20].

Nazef et al. [9] performed field evaluation of soil stabilized columns (SSC) used for flexible pavement embankment support and settlement control.
Jenck et al [17] explained that a higher the soil strength parameters and soil stiffness resulted the lower the maximum and differential settlement at the subsoil and pavement surface.
It was evidence in this simulation that the columns improved the pavement stiffness as indicated also by Nazef et al. [9].

Penzien et al[9] had assumed that the direction of the principal axis can be found when the general effect of three perpendicular horizontal components was considered if the earthquake motion was viewed as stationary random process, and each components in the principal axis is incorrelate with the other two.
The five group of earthquake waves are: Taft waves, El Centro waves, LLOLLELO waves, Compos waves and LUCERNE waves, and the details are shown in Table 2.
