TL;DR: In this article, the Raman spectra showed four modes, which increased in frequency as pressure was increased from ambient to 6.6 GPa, and the pressure coefficient, dνi/dP, for each mode has been estimated and used to evaluate the mode Gruneisen parameter γi for that mode.
Abstract: Alane has been subjected to Raman studies under static compression. The Raman spectra showed four modes, which increased in frequency as pressure was increased from ambient to 6.6 GPa. From the pressure dependence, the pressure coefficient, dνi/dP, for each mode has been estimated and used to evaluate the mode Gruneisen parameter γi for that mode. Independently the thermodynamic Gruneisen parameter γth has also been calculated using the pressure derivative of the isothermal bulk modulus value from the literature. Preliminary infrared spectra were also collected under ambient conditions and are discussed with those reported in the literature for alane polymorphs.

TL;DR: Evidence that S. aureus cells on a QAS‐coated planar surface are not exposed to a sufficient number of QAS molecules to produce significant mortality is provided, which has important implications for the development of self‐decontaminating coatings.
Abstract: This study investigates the effect of surface immobilization on the bactericidal function of a quaternary ammonium compound. Quaternary ammonium silane (QAS) coated planar surfaces did not produce any measurable mortality of Staphylococcus aureus, while 1 μm QAS-coated microparticles did produce S. aureus mortality. The experiments using QAS-coated microparticles indicate that the ability of QAS molecules to disrupt the cell wall is not hindered by covalent immobilization of QAS to a surface. These results provide evidence that S. aureus cells on a QAS-coated planar surface are not exposed to a sufficient number of QAS molecules to produce significant mortality. This result has important implications for the development of self-decontaminating coatings. Covalent immobilization is used to prevent leaching of the bactericidal compound. However, covalent immobilization may result in a significant tradeoff in bactericidal performance. Published in 2007 by John Wiley & Sons, Ltd.

10 Jan 2005TL;DR: In this paper, 2D and 3D flow analysis of CC airfoils using the steady Reynolds Averaged Navier-Stokes (RANS) method is presented.
Abstract: The flows about 2-D and 3-D bluff trailing edge circulation control (CC) airfoils are computed using steady Reynolds Averaged Navier-Stokes (RANS) methods. The 2-D foil is the NCCR 1510-7067 elliptical CC airfoil with circular and logarithmic spiral trailing edge geometries. The free stream Reynolds number, based on chord, is 5.45 × 10 5 , with a free stream Mach number of 0.12. For the circular trailing edge the slot height, blowing rate and angle of attack are varied, while for the logarithmic spiral only the blowing rate is varied. The 3-D foil is a semi-span wing with an elliptical cross section. It is run with a chord-based Reynolds number of 2 × 10 6 and two blowing rates. The 2-D flows are computed using the compressible, segregated solver, Fluent. 2-D results show that the full-Reynolds stress turbulence model (FRSM) predicts the correct jet detachment behavior for the circular trailing edge although the integrated lift forces are consistently underpredicted. The coanda jet detachment point for the logarithmic spiral trailing edge is predicted correctly for a lower blowing rate, but as blowing rate increases, the jet does not detach until it has wrapped around to the pressure side. We show additional 2-D results using mesh refinement via grid adaption and isotropic eddy viscosity turbulence models. The 3-D simulations use the incompressible segregated Fluent solver applying the k −ω SST turbulence model. Results show a slight attachment of the the coanda jet on the pressure side, but the results are generally encouraging.

TL;DR: In this article, the authors use the maximum likelihood estimation (MLE) method to incorporate the censored data properly, which alleviates the handling of runouts and censored data by using the MLE method.
