    Factors governing the vulnerability of DRL operant performance to the effects of ethanol (1973)

    Notizen: Abstract The effects of various doses of ethanol on DRL performance was examined in rats under conditions of cued and non-cued DRL tasks and under conditions of low versus high baseline performance criteria. The dose-level at which ethanol produced a significant reduction in number of responses and reinforcements interacted in a complex fashion with level of baseline performance, the cue conditions, and the order of DRL tasks. Generally, performance was impaired at a lower dose level for groups initially trained to a low criterion of DRL performance than for groups later trained to a higher criterion of DRL performance, regardless of cue condition. Further, the dose level at which ethanol impaired performance (as indicated by number of reinforcements obtained) under non-cued DRL conditions was lower than that for the cued DRL conditions, but only on the initial task where baseline DRL performance criterion was lower. Finally, the group with a higher baseline level of responding (i.e., poorer DRL performance) was more vulnerable to the disrupting effects of ethanol on this measure than groups with lower baseline response rates.

    Notizen: A theoretical approach to equilibrium calculations for homogeneous real fluid mixtures is presented. The overall approach is developed for, although not theoretically restricted to, a corresponding states equation of state, z(Tr, pr). The method is applied to the gaseous ammonia synthesis data of Larson and Dodge. Excellent agreement was attained with the data. Quite significant improvement was observed over the ideal gas and ideal solutions approximations.

    Transport properties of polyvinylpyridinium anion-exchange membranes (1974)

    Notizen: Measurements have been made of the electrical conductivity of water-saturated heterogeneous anion-exchange pyridinium membranes in their carbonate and hydroxyl ionic forms as a function of temperature. The pyridinium membranes were prepared from quaternized poly-4-vinylmethyl-pyridinium resin electrolyte incorporated in a polyvinylidene fluoride matrix; the ratio of the pyridinium electrolyte to polyvinylidene fluoride was 4 to 1 by weight.The ion-exchange capacity and water content of these anion-exchange pyridinium membranes were measured. Corresponding Arrhenius activation energies of ion transport of carbonate and hydroxyl counter-ions have been calculated. Self-diffusion coefficients and the equivalent conductances of these pyridinium membranes in their carbonate and hydroxyl counter-ion forms have also been determined over a wide temperature range and compared to the reported values for present quaternary ammonium anion-exchange membranes.

    Notizen: The electret potentials developed by reverse osmosis electret membranes help control the undesirable deposition of charged colloidal particles on the membrane surfaces during membrane desalination. These antifouling electret membranes should help prevent the costly flux declines normally associated with deposition of colloidal iron oxides on the reverse osmosis membrane surfaces.Homocharge and heterocharge behavior of cellulose acetate membrane electrets have been studied. Asymmetric reverse osmosis membranes and dense membrane films were studied. The homocharge and heterocharge of cellulose acetate reverse osmosis electret membranes have been explained.
