In the paper the author reviews basic tendencies of the global and national trade union movement and the influence of these trends on social partnership principles implementation and the trade unions adaptability to permanent changes in socioeconomic field. The author analyses foreign trade unions operational experience, detects development of the level of national trade-unionism and its place and role in European integration and globalization processes. The priorities of Ukrainian trade-unionism development are identified. [ABSTRACT FROM AUTHOR]

The heat capacity of lithium hexafluoroarsenate is determined in the temperature range 50-750 K by adiabatic and differential scanning calorimetry techniques. The thermodynamic properties of LiAsF6 under standard conditions are evaluated: Cp0 (298.15 K)= 162.5 ± 0.3 J/(Kmol), S0(298.15 K) = 173.4±0.4J/(Kmol), Pρ(298.15 K) = 81.69 ± 0.20 J/(K mol), and H0(298.15 K) -H0(0) =27340 ± 60 J/mol. The Cp(T) curve is found to contain a lambda-type anomaly with a peak at 535.0 ± 0.5 K, which is due to the structural transformation from the low-temperature, rhombohedral phase to the high-temperature, cubic phase. The enthalpy and entropy of this transformation are 5.29±0.27 kJ/mol and 10.30±0.53 J/(K mol), respectively. The thermal decomposition of LiAsF6 is studied. It is found that LiAsF6 decomposes in the range 715-820 K. The heat of decomposition, determined in the range 765-820 K using a sealed crucible and equal to the internal energy change ΔUr (T), is 31.64 ± 0.08 kJ/mol. [ABSTRACT FROM AUTHOR]
