The denaturation data are analyzed based on the effective Gibbs free energy (ΔG°eff) approach and the chemical denaturation parameters including ΔG°eff, m value and equilibrium unfolding constant (KU) were obtained.
Two new classes of life distributions, namely the class of new better than its equilibrium life in convex ordering (NBELC), and its dual class, the class of new worse than its equilibrium life in convex ordering (NWELC), are introduced.
Vapor-liquid equilibria of two binary systems, i.e. n-heptane-toluene and n-heptane-phenol, were determined with a equilibrium still modified for this work. Then from the equilibrium data of the following three binary systems, i.e. n-heptane-toluene, n-heptane-phenol and toluenephenol, the vapor-liquid equilibrium of the ternary system n-heptane-toluene-phenol were calculated by the van Laar 'two suffix' equation. The calculated results checked with the experimental data. The logarithmic v...
The vapor pressure of heptene-(S) was determined. Vapor-liquid equilibria of two binary systems, i.e. toluene-heptene-(3), n-heptane-heptene-(3), and the ternary system toluene-n-heptane-heptene-(3) were determined with the Gillespie's type equilibrium still. With the equilibrium data of the following three binary systems i.e. n-heptane-toluene, ?heptane-heptene-(3), toluene-hcptene-(3) the vapor-liquid equilibrium of the ternary system toluene-n-heptane-heptene-(3) was calculated by means...
For the purpose to obtain new pyroceram materials, the crystalline phases of glasses in the system Li_2O-Al_2O_3-SiO_2 were studied. Glass batches of compositions in the tridymite,lithium metasilicate, lithium disilicate and spodumene primary phase regions of Li_2O—Al_2O_3—SiO_2 system were melted and crystallised.The resulting crystalline phases were identified with X-ray diffraction method. Since the primary phases in equilibrium diagram usually did not appear in the corresponding 'pyroceram', the a...
