Physical properties of all powders are shown Table 1.
Fig.1 shows the value of friction coefficient as a func- tion of wear time for four types of samples.
When sliding, after a certain time, the friction coefficient increases sharply from o.1 to maximum.

The molar ratio of Ca to P was 1.67: 1.
Moreover, infrared transmittance spectra confirmed that the HAp powder calcined at 1100 °C corresponded to the phosphate group in PO43- with significant characteristic peaks at 1026.5 and 563.9 cm-1 and the structural OH− vibrational modes are observed in HAp samples at 3640.8 cm−1 as shown in Figs. 3, which are match well with the reported work [12]. 3640.8 3640.8 1026.2 564.9 3641.2 563.9 1026.8 563.9 1026.5 %Transmittance %Transmittance %Transmittance Wavenumbers (cm-1) Wavenumbers (cm-1) Wavenumbers (cm-1) Fig. 3 FTIR spectra of HAp powders calcined at 1100 °C produced from (a) hen eggshells, (b) duck eggshells and (c) quail eggshells.

When tested at 290°C, the weld exhibited characteristics of dynamic strain ageing (DSA), which was more significant when strain rate was decreased from 1x10-6 (1/s) to 3.1 x10-7 (1/s).
The chemical compositions of the three metals are shown in Table 1.

As shown in Figure 1a, diarylethene 1a exhibited a sharp absorption peak in hexane at 302nm (ε, 4.2 × 104 mol-1 L cm-1) due to π→π* transition, while upon irradiation with UV light, a new visible absorption band centered at 479 nm (ε, 2.0 × 104 mol-1 L cm-1) emerged due to the formation of closed-ring isomer 1c, and accordingly, the solution color changed from colorless to Orange Red.
Fig. 1 Absorption spectral and color changes of compound 1 in hexane (2.0 × 10-5 mol L-1) (a) and in PMMA film (10%, w/w) (b).
The concentration of solution is 2.0 × 10-5 mol L-1.

Horizontal displacements with 20 mm (pushing) induced deformation on transition slab head are presented in Fig. 1.
transition slab abutment pavement Figure 1.
Foundation thickness was 0,8 m, and width 3,0 m. 1,2 m wide part of the foundation was considered as buried in the embankment, behind the abutment wall.
For bridge deck to abutment wall stiffness ratio exceeding 2:1, substitution with infinitely stiff bending restraint proved to be sufficient.
