Re-examination of the scaling roughness function for κ-type rough walls using a servo-controlled wall drag balance

Conclusion The authors would like to underline errors in the mean velocity measurements in previous paper (Pineau et al. 1987). The direct drag measurements and Reynolds stress data were confirmed, and the new mean velocity profiles, in conjunction with the drag data resulted in exactly the same roughness scaling function as proposed by Perry and Joubert (1963) for the same k-type roughness.     

HEAT-SET WHEY PROTEIN EMULSION GELS: ROLE OF ACTIVE AND INACTIVE FILLER PARTICLES

Viscoelastic properties of heat-set whey protein emulsion gels containing active filler (protein-covered droplets) and inactive filler (surfactant-covered droplets) have been investigated at small and large deformations using a controlled stress rheometer. Data are reported as a function of protein concentration, oil volume fraction, and average emulsion droplet size. The active filler enhances the gel strength, whereas the inactive filler reduces the gel strength. The higher the elastic modulus of the protein gel matrix, the less the effect of the active filler, but the greater the effect of the inactive filler (and vice versa). Higher oil volume fraction and reduced particle size both intensify the effect of the filler. The large deformation behaviour of a heat-set protein gel or a heat-set emulsion gel containing up to 20 vol% oil is entropic in character, whereas an emulsion gel of higher filler content behaves more like a typical enthalpic particle gel.     

The Trans-Influence In Platinum(II) Complexes. An Application of 129I-Mössbauer Spectroscopy

The ¹²⁹I-Mössbauer spectra of several cis-diioda-and two hydridoiodo-platinum(II) complexes have been obtained at 4.2°K. The quadrupole coupling constants of the cis complexes vary systematically with the nature of the neutral ligands, indicating the operation of a Trans-influence. The values for the hydrides are very low, showing a large trans-influence for this ligand.     

A targetable fluorescent probe for imaging hydrogen peroxide in the mitochondria of living cells

We present the design, synthesis, and biological applications of mitochondria peroxy yellow 1 (MitoPY1), a new type of bifunctional fluorescent probe for imaging hydrogen peroxide levels within the mitochondria of living cells. MitoPY1 combines a chemoselective boronate-based switch and a mitochondrial-targeting phosphonium moiety for detection of hydrogen peroxide localized to cellular mitochondria. Confocal microscopy and flow cytometry experiments in a variety of mammalian cell types show that MitoPY1 can visualize localized changes in mitochondrial hydrogen peroxide concentrations generated by situations of oxidative stress.     

Calculation of the transport and relaxation properties of methane. I. Shear viscosity, viscomagnetic effects, and self-diffusion

Transport properties of pure methane gas have been calculated in the rigid-rotor approximation using the recently proposed intermolecular potential energy hypersurface [R. Hellmann et al., J. Chem. Phys. 128, 214303 (2008)] and the classical-trajectory method. Results are reported in the dilute-gas limit for shear viscosity, viscomagnetic coefficients, and self-diffusion in the temperature range of 80-1500 K. Compared with the best measurements, the calculated viscosity values are about 0.5% too high at room temperature, although the temperature dependence of the calculated values is in very good agreement with experiment between 210 and 390 K. For the shear viscosity, the calculations indicate that the corrections in the second-order approximation and those due to the angular-momentum polarization are small, less than 0.7%, in the temperature range considered. The very good agreement of the calculated values with the experimental viscosity data suggests that the rigid-rotor approximation should be very reasonable for the three properties considered. In general, the agreement for the other measured properties is within the experimental error.
