    Tests of thermodynamic theory of relative stability in one-variable systems (1993)

    Notes: Schlögl's criterion for equistability of two stable stationary states of an inhomogeneous chemical kinetic system is valid only for single-variable cases dependent along a single spatial coordinate. We test the thermodynamic theory, developed in the preceding article for multivariable systems, in one dimension by comparison with calculations based on the deterministic reaction-diffusion equation for a cubic Schlögl model (single variable). This reaction-diffusion system is equivalent to a coupled multivariable system. The prediction of the thermodynamic theory of equistability approaches Schlögl's result as the length of the system increases. We also test the theory for an optically bistable (ZnSe) system which has been studied experimentally; in this system, temperature is the variable, and there is transport by thermal conduction. Again, we find that the prediction of the multivariable thermodynamic theory approaches the result from the deterministic kinetic equation as the length of the system increases. Further, the single-variable thermodynamic theory of relative stability of homogeneous steady states agrees with experiments and with the prediction of the deterministic equation.

    Thermodynamic and stochastic theory of reaction-diffusion systems with multiple stationary states (1993)

    Notes: The thermodynamic and stochastic theory of chemical systems far from equilibrium is extended to reactions in inhomogeneous system for both single and multiple intermediates, with multiple stationary states coupled with linear diffusion. The theory is applied to the two variable Selkov model coupled with diffusion, in particular to the issue of relative stability of two stable homogeneous stationary states as tested in a possible inhomogeneous experimental configuration. The thermodynamic theory predicts equistability of such states when the excess work from one stationary state to the stable inhomogeneous concentration profile equals the excess work from the other stable stationary state. The predictions of the theory on the conditions for relative stability are consistent with solutions of the deterministic reaction-diffusion equations. In the following article we apply the theory again to the issue of relative stability for single-variable systems, and make comparison with numerical solutions of the reaction-diffusion equations for the Schlögl model, and with experiments on an optically bistable system where the kinetic variable is temperature and the transport mechanism is thermal conduction.

    RELEASE OF BETAMETHASONE DERIVATIVES FROM OINTMENTS—IN VIVO AND IN VITRO STUDIES (1969)

    Notes: SUMMARY.— The vasoconstrictor test of McKenzie and Stoughton (1962) has been adapted for studying the release of betamethasone 17-valerate and 21-desoxy betamethasone 17-propionate from ointments. Vasoconstriction on the skin of volunteers was assessed quantally by noting presence or absence of vasoconstriction or quantitatively by measuring diameters of vasoconstricted areas. The quantitative method employs corticosteroid doses higher than those used in the quantal method of McKenzie and Stoughton. The vasoconstrictor potencies of 3 betamethasone derivatives have been compared using the quantitative method in order to confirm its validity. The quantitative method was used for comparing various ointment bases with betamethasone 17-valerate or 21-desoxy betamethasone 17-propionate. High relative potencies were obtained by the inclusion of propylene glycol in the ointments. Ointments containing betamethasone 17-valerate and varying amounts of hydrogenated lanolin were compared.The quantitative and quantal methods showed that relative vasoconstrictor potency increased or diminished respectively with increased concentration of hydrogenated lanolin. The effect of hydrogenated lanolin in vehicles on the release of betamethasone 17-valerate was studied using two in vitro model systems and the results are discussed in relation to those of the in vivo experiments.

    A population study of Barbus barbus (L.) in the River Severn, England (1974)

    Notes: The results of the application of Schnabel (Chapman modification), Schumacher & Eschmeyer, Fisher & Ford, and Jolly capture-recapture techniques on the Barbus barbus (L.) population in four areas of the middle Severn are compared. The survival of tagged fish varied in different areas and fish released in some time periods were less vulnerable to recapture than fish released from other samples. It is suggested that the shoaling behaviour of Barbus barbus resulted in non-random mixing of marked fish. The average population size of Barbus barbus greater than 18 cm in length in each of the four sections for the total period of investigation gave population densities ranging from 0.024/m2 to 0.202/m2.

    Notes: The contents of the stomachs of 38 rainbow trout stocked in Llyn Alaw, Anglesey, in August 1969 and caught between October 1969 and February 1970 were analysed. The fish were actively feeding on the bottom fauna throughout the winter and 21 of the stomachs were full or distended. The mean volume of the contents of the stomachs was 2–8 times greater than that of the contents of stomachs of similarly sized brown trout caught at the same time.
