The natural aeration obtained was sufficient to prevent the growth of anaerobic processes from reaching a certain depth and hence no exopolymers are released which would otherwise facilitate anaerobic bacterial colonization of the stones to such a level that siltation appears.
Calculations perform for the elements from surface to a certain depth or from a certain point to the next desired depth.
Many planers offer the capability to "lock" the planer from cutting beneath a certain depth via a mechanism called a depth stop.
Figure 1b shows the one-way travel time of S waves from the surface to a certain depth (depth-time curve) obtained at 14 wells of the NIED.
(b) The p-type conductivity occurs in the bulk layer below a certain depth from the surface [20, 29].
This process might induce a material deformation and herewith strength properties enhancement up to a certain depth from the coating surface.
The crack shape is affected by a radial decreasing hydrostatic stress field originating in the plastic deformation zone underneath the impression and with its centre at a certain depth from the surface.
Employing the X-ray diffraction technique, the residual stresses were measured in the coating before and after micro-blasting and the related stress changes were determined at a certain depth from the film surface.
From Equation 1, the one-way travel time of S wave t z) from z = 0 to a certain depth z is analytically calculated as follows: t z)=frac{Delta V}{alpha left({V}_0+Delta Vright)} ln frac{left({V}_0+Delta Vright) exp left alpha mathrm{z}/Delta Vright -Delta Vright -Delta
