“…For some normal alkanes (Koak and Heidemann, 1996), the PHSC equation of state does not correlate the thermodynamic properties of saturated liquids as well as lattice-based models such as the lattice-fluid theory of Sanchez and Lacombe (1976;•2 1978). When applied to LLE for dilute and semidilute polymer solutions, the PHSC equation of state overestimates the equation-of-state effect that causes lower critical solution temperatures (LCSTs) at elevated temperatures (Hino et al, 1996). In polymer solutions, the PHSC equation of state predicts LCSTs at temperatures lower than those measured.…”

“…When the equation-of-state parameters for polymers are obtained from polymer PVT data, equation-of-state theories often overestimate the equation-of-state effect in polymer solutions, predicting LCSTs which are lower than those measured. As discussed in detail by Hino et al (1996), the original PHSC equation of state…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…A graphical representation is proposed on Figure in which the ideal mixture case is compared to a constant (γ 2 = 2) and also to a variable activity coefficient (γ 2 = 2 and 1/γ 2 · dγ 2 / d x 2 = 1), which is more realistic. Note that both the chosen values of coefficient of activity and their variations are typically in the orders of magnitude encountered in real systems …”

“…The empirical parameter ν p (from eq 8), introduced by Hino et al 58 for a perturbed hard-sphere-chain EOS and further extended by Lee et al 1 for the PLJC, has been used successfully to predict phase behavior of various polymeric solutions. This empirical term arises from the fact that the perturbation term overpredicts the attractive interactions between polymer chains.…”
