Abstract: A fluidized-bed reactor for the chemical vapor deposition of a coating on a substrate surface is described. The reactor enables high rates of deposition and a highly homogeneous coating by modifying the boundary layer formed between the gasified reactive gas stream and the substrate. The boundary layer is minimized by the presence of an exhaust outlet placed in close proximity to the center of the surface of the substrate and/or the presence of a gas inlet capable of injecting a tangential stream of gas which results in a swirling radial flow of reactive gas. Methods of forming a metal coating on a surface of a substrate using the reactor are provided as well.

Abstract: Novel polyketides and novel methods of efficiently producing both new and known polyketides, using recombinant technology, are disclosed. In particular, a novel host-vector system is described which is used to produce polyketide synthases which in turn catalyze the production of a variety of polyketides.

Abstract: A method is provided for calibrating sensors used to analyze characteristics of physiologic fluids such as blood. The method involves the use of a sensor assembly having an analyte-responsive sensor in communication with a passageway which is in divertable fluid communication with a physiologic line and a conduit by which a reference sample may be introduced into the passageway. The method involves exposing the sensor to the reference sample, thereby producing a sensor response. The method also allows performing quality control on the sensors. Also provided is an apparatus with which the claimed method may be practiced.
