Decarburization is due to the reactions involving carbon which lead to the reduction of the powder oxides.

Powder X-ray diffraction (PXRD) data, collected on a Siemens D-5000 diffractometer, were used to confirm phase purity.
Indeed, a comparison of theoretical densities show only a small reduction in density for γ-Ca(PO3)2 over β-Ca(PO3)2 of ~2.3% [10,11].

In addition, because of bringing the detrimental result as the toxic gas mainly generated in the misfire process with the small quantity to the human body, the discharge reduction of CO and monitoring are needed.
The selected ADC chip is an A/D Converter which is suitable for the gas concentration measurement for the high resolution measurement as a chip having the effective bit of 19bit in the maximum 20KHz Data rate.

The effect of frequency range and number of measurements/decade on the experiment duration However, taking into account both table, it results that a significant reduction in experimental duration (almost half the time) can be obtained employing 10 measurements/decade without running the risk of compromising the experimental results.
A Nyquist plot of a PESA (polysulphone based membrane) and the corresponding EIS value of the real part of impedance, R1; d = 0.0211cm, σ= 1.418.10-5 Ώ -1cm-1 As one can see, the circular regression correlation coefficient, n = 0.974, obtained from 30 points regression is above 0.95 which suggest a very good fit of the experimental data with the Randles simulated values.

Then this modeling approach in providing accurate predictions required for big signal, for example, measured loadpull information, the GaN HEMT’s scattering parameters and corresponding simulated data are compared in the following Table. 1 and Fig. 2.
The insertion loss of the hybrid coupler can cause a reduction in total added power and combining efficiency, so it is an important task for Wilkinson design.

conventional seismic load that may be supported by the structure, base shear force, respectively; necesarS is the conventional seismic load, base shear force determined according to §5.3 of P100/92 provisions [1], which considers the structure respectively as being new and calculated with the relation done in Eq.2 [2]: rrsr r necesar kc GcS ε⋅ψ⋅β⋅⋅α= ⋅= (2) in which: rc is the global seismic coefficient corresponding to the r mode of vibration; G , gravitational loads resultant for the whole structure; α, building importance coefficient, depending on structural importance classes; sk , seismic intensity coefficient, depending on the design seismic location; rβ , dynamic gain coefficient for the r vibration mode, depending on the spectral composition of the seismic movement of the building's location; ψ, coefficient of seismic effects reduction
Although the method we used is deterministic, the case study of the shear walls structure has offered a data base that proves to be sufficient in making the decision to seismically rehabilitate the structure as this is one of the quality procedures used in assessing the seismic safety of structures.

Chang (2004) finished the numerical and experimental investigation on residual stress and compared the numerical solutions with experimental residual stress data [4].
Instead, the method deactivates them by multiplying their stiffness by a severe reduction factor.
