The activity coefficient data were reported for (water + potassium chloride + DL-valine) at T = 298.15 K and (water + sodium chloride + L-valine) at T = 308.15 K. The measurements were performed in an electrochemical cell using ion-selective electrodes. The maximum concentrations of the electrolytes

✦ Synopsis
Fatigue behavior and phase transformation in the metastable austenitic steels AISI 304, 321 and 348 were investigated in the temperature range from -60°C to 25°C by means of stress-strain hysteresis, electrical resistance and magnetic measurements. The steels show differences in austenite stability, which lead to significant changes in deformation induced martensite formation and fatigue behavior in total strain controlled low cycle fatigue tests. Dependent on the type of steel and testing temperature similar values of martensite fraction but different strengths developed.

The speed of sound u has been measured in {(1x 2 )C 2 H 6 + x 2 CO 2 }, with x 2 ≈ 0.6, along seven isotherms at temperatures between T = 220 K and T = 450 K by means of a spherical resonator. The greatest pressure on each isotherm was approximately p = 1.2 MPa except at T = 220 K where, to avoid co
The equation x t y c t x t y is considered in the critical case. For it, the ȧsymptotic behavior of dominant and subdominant solutions is studied. A generalization is made and connections with known results are discussed.
