FIGURE 12.8 Schematic indication of the phenomena occurring on seasoned wood treated with antiseptic agents immediately after the cut. (a) To avoid on the intact pole, subject to unprotected cracks, possible access points for spores and insects, (b) Preferable on poles carved before the antiseptic treatment, in order to avoid the formation of unprotected cracks. 

The failure of systems with dispersed fillers (exemplified by polystyrene plus glass spheres with different treatment) was studied by subjecting specimens to deformation in the microscope field [255,256]. Where adhesion was good the cracks were observed to be formed near the glass sphere pole, in regions corresponding to the maximum deformation, where adhesion was poor, anywhere between the pole and the equator. It was discovered that microcracks began to... 

Figure 7. Cl MS (CH, 150 °C) generated (M+l)+ ion was quadra-pole selected and subjected to collision activated decomposition (N2) to give the mass spectrum (6).

Too small a value of xc means too large a Kc and therefore saturation. System response is subject to imperfect pole-zero cancellation. 

The extensive layered sediments at the south pole, which contain water ice, will provide information on climatic variations. The subsurface sounding radar instrument SHARAD (Shallow Radar) on board the Mars Reconnaissance Orbiter carried out a detailed cartographic study of the subsurface at the Martian south pole. The data indicate that the sediments there have been subjected to considerable erosion (R. Seu et al 2007). The density of the material deposited at the Martian south pole was calculated by M. T. Zuber and co-workers by combining data from the gravitational field with those from various instruments on board the Mars Orbiter, they obtained a value of 1,200 kg/m3. This value corresponds to that calculated for water ice containing about 15% dust (Zuber et al 2007).
