    Notes: L-Lysine α-oxidase from Trichoderma viride Y244-2 is immobilized in a gelatin support and fixed on a pO2 sensor. The enzyme electrode obtained is used in a continuous flow system in order to measure the concentration of L-lysine in a fermentor. The sample oxygen-content dependance of the signal is minimized because of the enzyme support properties. The enzyme electrode response is set for lysine concentration from 0.2mM to 4mM. The specificity of lysine is tested with other amino acids. The enzyme membrane for lysine electrode can be used 3000 times or stored six months with good stability.

    Notes: Lead selenide (PbSe) particulate films, composed of highly oriented, equilateral triangular crystals, have been in situ generated by the exposure of arachidic-acid- (AA) monolayercoated aqueous lead nitrate [Pb(NO3)2] solutions to hydrogen selenide (H2Se). The AA coated PbSe films, at different stages of their growth, were transferred to solid substrates and characterized by transmission electron microscopy (TEM), electron diffraction, and atomic force microscopy (AFM). The epitaxial growth of PbSe crystals has been rationalized in terms of matching the {111} plane of crystalline PbSe and the (100) plane of the hexagonally close-packed AA monolayer. The parallel alignment of the ≤110〉 and ≤001〉 axes and the perpendicular alignment of the ≤110〉 axis to the monolayer have been suggested to be responsible for the observed formation of rod-like PbSe particles. The presence of a negatively charged monolayer has been found to be an essential requirement for the oriented growth of PbSe crystals. © 1994 Wiley-Liss, Inc.

    Notes: A class of shock-capturing Petrov-Galerkin finite element methods that use high-order non-oscillatory interpolations is presented for the one-dimensional compressible Euler equations. Modified eigenvalues which employ total variation diminishing (TVD), total variation bounded (TVB) and essentially non-oscillatory (ENO) mechanisms are introduced into the weighting functions. A one-pass Euler explicit transient algorithm with lumped mass matrix is used to integrate the equations. Numerical experiments with Burgers' equation, the Riemann problem and the two-blast-wave interaction problem are presented. Results indicate that accurate solutions in smooth regions and sharp and non-oscillatory solutions at discontinuities are obtainable even for strong shocks.
