Capacitance measurements The behaviour of the type of contact is typical of the situation when an injection or ohmic contact is provided and offers confirmation that Ag electrodes do indeed establish ohmic contacts to PbS as previously observed by Ubale et al. [3].

., Gapharov et al., 1996 and 1998a) which are
exploited in the conditions of hydrogen embrittlement (e.g., Gangloff, 1983).
Effective Young modulus, E/(1−v 2) was considered 10 11 Pa for metal and 10 10 Pa for coating (e.g., Goldstein at el., 1977 and 1985; Gangloff, 1983).
Note that depending upon the initial hydrogen concentration, c0, in steel, the delamination time, t, in the context of the proposed model, changes from minutes to years, which is consistent with the observations (e.g., Goldstein et al., 1977 and 1985; Johnson, 1984; Troiano and Hehemann, 1984).

Gernot (2001) and
Marcial et al. (2003) introduced and summarized various reinforcing methods for earth houses.
Figure1: Dimensions (mm) and configuration of specimen A (left), B (right) Model Similitude The laws of similitude for linear elastic behavior (LinGao et al. 2000) were used for model similitude in the test.
The earthquake motion used in the tests was based on the El-centro earthquake wave (1940).

Thermo-Mechanical Processing and Dilatometry
For thermo-mechanical processing and dilatometric study, a Baehr Dil 805D thermo-mechanical simulator, shown in Fig. 1, was used.
Myszka et al. reported that isothermal transformation of ausferrite refines the ferrite plates which tend to form a typical feathery pattern indicating the direction of the plate growth [12].
