    Notes:
    Binary diffusion coefficients at high dilution are measured for ethane and ethylene dissolved in cyclohexane at temperatures from 280.5 to 363.2 K and for benzene in cyclohexane and n-hexane up to their critical temperatures. With the effective hard-sphere diameters backed out from self-diffusion data from both solute and solvent molecules and fitted to Protopapas, Anderson, and Parlee's formula, the prediction with the Sung–Stell theory is found to agree to within ±7% of experimental data for wide ranges of solute-to-solvent mass and size ratios at temperatures up to the critical point.

    Notes:
    The translational diffusion coefficients for three relatively short, nearly monodisperse polystyrene chains (with molecular weights 2000, 4000, and 9000) in liquid cyclohexane have been measured up to 523.2 K using the extended Taylor dispersion method. The resultant hydrodynamic radii are successfully interpreted with the freely jointed chain model corrected for the approximations intrinsic to Kirkwood's theory with Stokes' radius as the only adjustable parameter, which is found to decrease with chain length but approach a constant value for long enough chains. The experimentally observed hydrodynamic radii of polystyrene standards with molecular weights 17,500, 50,000 and 100,000 at 308.2 K conform quite well to the values predicted with the approach formulated in this work.

    Description:
    We use laboratory experiments to test for one of the foundations of the rational voter paradigm - that voters respond to probabilities of being pivotal. We exploit a setup that entails stark theoretical effects of information concerning the preference distribution (as revealed through polls) on costly participation decisions. We find that voting propensity increases systematically with subjects' predictions of their preferred alternative's advantage. Consequently, pre-election polls do not exhibit the detrimental welfare effects that extant theoretical work predicts. They lead to more participation by the expected majority and generate more landslide elections.

    Notes:
    Pneumocystis infection in athymic nude mice lungs showed a particularly high trophozoite to cyst ratio. A similar observation was obtained from a study of a patient with lymph node infection with Pneumocystis. Eosinophilic foamy masses in these sites were observed by light microscopy . With the electron microscope, the masses were seen to be composed of large aggregates of trophozoites. Cystic forms (precyst, cyst and empty cyst) were extremely scarce in comparison with the huge numbers of trophozoites. These cystic forms were mostly undergoing degeneration. These observations indicate that the mode of proliferation in both situations was predominantly asexual, that is, proliferation by trophozoites, suggesting that certain conditions may enhance asexual reproduction or depress the formation of cysts.

    Notes:
    The standard Gibbs energies of formation of RuO2 and OsO2 at high temperature have been determined with high precision, using a novel apparatus that incorporates a buffer electrode between the reference and working electrodes. The buffer electrode absorbs the electrochemical flux of oxygen through the solid electrolyte from the electrode with higher oxygen chemical potential to the electrode with lower oxygen potential. The buffer electrode prevents polarization of the measuring electrode and ensures accurate data. The standard Gibbs energies of formation (ΔfG°) of RuO2, in the temperature range of 900–1500 K, and OsO2, in the range of 900–1200 K, can be represented by the equations 〈displayedItem type="mathematics" xml:id="mu1" numbered="no"〉〈mediaResource alt="image" href="urn:x-wiley:00027820:JACE1745:JACE_1745_mu1"/〉 where the temperature T is given in Kelvin and the deviation of the measurement is ±80 J/mol. The high-temperature heat capacities of RuO2 and OsO2 are measured using differential scanning calorimetry. The information for both the low- and high-temperature heat capacity of RuO2 is coupled with the ΔfG° data obtained in this study to evaluate the standard enthalpy of formation of RuO2 at 298.15 K (ΔfH°298.15K). The low-temperature heat capacity of OsO2 has not been measured; therefore, the standard enthalpy and entropy of formation of OsO2 at 298.15 K (ΔfH°298.15K and S°298.15K, respectively) are derived simultaneously through an optimization procedure from the high-temperature heat capacity and the Gibbs energy of formation. Both ΔfH°298.15K and S°298.15K are treated as variables in the optimization routine. For RuO2, the standard enthalpy of formation at 298.15 K is ΔfH°298.15K(RuO2) =−313.52 ± 0.08 kJ/mol, and that for OsO2 is ΔfH°298.15K(OsO2) =−295.96 ± 0.08 kJ/mol. The standard entropy of OsO2 at 298.15 K that has been obtained from the optimization is given as S°298.15K(OsO2) = 49.8 ± 0.2 J·(mol·K)−1.

    Notes:
    On lowering the chemical potential of diatomic oxygen, the compound YBa2Cu4O8 was found to decompose into a mixture of YBa2Cu3O6+x and CuO. The equilibrium oxygen potential corresponding to this decomposition has been measured from 870 to 1150 K using a solid-state cell incorporating yttria-stabilized zirconia as the solid electrolyte and pure oxygen at a pressure of 1.01×105 Pa as the reference electrode: Pt, O'2||YBa2Cu4O8+YBa2Cu3O6+x+CuO(parallel)(Y2O3) ZrO2(parallel)O2(1.01×105 Pa), Pt. The low oxygen potential boundary for the stability of YBa2Cu4O8 can be represented by ΔμO2=−238 900+207.7 T(±800) J mol−1. At the standard pressure of oxygen (1.01×105 Pa) the decomposition occurs at 1150 K.

    Notes:
    A composition-graded solid electrolyte has been used to determine the standard Gibbs free energy of formation of lanthanum zirconate (La2Zr2O7) from the component oxides lanthana (La2O3) (A-rare earth) and zirconia (ZrO2) (monoclinic) in the temperature range of 870–1240 K. The cell used for measurement can be represented as Pt, O2, CaO + CaF2∥ CaF2| (LaF3)x(CaF2)1-x∥LaF3+ La2Zr2O7+ ZrO2, O2, Pt x=0 x=0.32 A composition-graded electrolyte has been introduced to compensate the solubility effects of the electrode material (lanthanum fluoride, LaF3) in the solid electrolyte (calcium fluoride, CaF2). The ability of the graded electrolyte to gen-erate a Nernstian response is demonstrated, using electrodes with known fluorine chemical potentials. For the reaction La2O3 (A-rare earth) + 2ZrO2 (monoclinic) → La2Zr2O7 (pyrochlore), the Gibbs free energy change (ΔG°f,ox) is given by the formula −133800 −10.32T (±4500) (in units of J/mol). The enthalpy and entropy of formation of La2Zr2O7 obtained in this study are in good agreement with calorimetric data. The “third-law” enthalpy of formation of La2Zr2O7, from the component oxides at 298.15 K, is −133.8 ± 5 kJ/mol.

    Notes:
    Solid-state miscibility gap in the pseudo-binary calcium oxide-strontium oxide (CaO-SrO) system is delineated by X-ray diffractometry studies on samples equilibrated either under vacuum or in a flowing inert-gas atmosphere at temperatures of 973-1273 K. For the CaxSr1−xO solid solution, an asymmetric phase boundary that is characterized by a critical temperature of 1173 (±3) K and a composition of x= 0.53 (±0.01) is obtained. The excess Gibbs energy of mixing of the solid solution, which is derived from the experimental phase-boundary compositions and temperatures, can be represented by the expression ΔGE=x (1−x)[(27040 − 5.82 T) x+ (24915 − 5.34 T)(1 −x)] (in units of J/mol). It is necessary to include excess entropy terms to obtain a good fit to the experimental data. The chemical spinodal curve is computed from the thermodynamic parameters. The results obtained in this study are compared with phase-diagram and calorimetric information that is available in the literature.

    The standard Gibbs energy of formation of the spinel MgAl2O4 from component oxides, MgO and α-Al2O3, has been determined in the temperature range 900 to 1250 K using a solid-state cell incorporating single-crystal CaF2 as the solid electrolyte. The cell can be represented as—Pt,O2,MgO+MgF2|CaF2|MgF2+MgAl2O4+α-Al2O3,O2,Pt—The standard Gibbs energy of formation from binary oxides, computed from the reversible emf, can be represented by the expression—capdeltaG°f,ox=−23600 − 5.91T(±150) J/mol—The ‘second-law’ enthalpy of formation of MgAl2O4 obtained in this study is in good agreement with high-temperature solution calorimetric studies reported in the literature.

    Background  The inflammation in acne vulgaris is widely thought to be induced by an immunological reaction, but the role of Propionibacterium acnes is unclear.Objectives  To examine the local host response mechanism of a keratinocyte cell line 3 h and 6 h after stimulation with viable and heat-killed P. acnes.Methods  The quantitative expression of cytokines was measured at the mRNA level by real-time reverse transcription–polymerase chain reaction.Results  The coincubation of a keratinocyte cell line with viable, but not heat-killed, P. acnes modulated an adequate cytokine response for interleukin (IL)-1β, granulocyte/macrophage colony-stimulating factor and IL-8. High-performance liquid chromatographic analysis of the in vivo porphyrin pattern secreted by P. acnes revealed a predominance of coproporphyrin III in acne lesions. This same porphyrin fraction also modestly induced IL-8 expression by keratinocytes.Conclusions  This cytokine pattern may favour a chemotactic response and implicates P. acnes and coproporphyrin III in the recruitment of inflammatory cells to the site of infection and in the development of acne lesions.
