Abstract: An apparatus for acoustic concentration of particles in a fluid flow includes a substantially acoustically transparent membrane and a vibration generator that define a fluid flow path therebetween. The fluid flow path is in fluid communication with a fluid source and a fluid outlet and the vibration generator is disposed adjacent the fluid flow path and is capable of producing an acoustic field in the fluid flow path. The acoustic field produces at least one pressure minima in the fluid flow path at a predetermined location within the fluid flow path and forces predetermined particles in the fluid flow path to the at least one pressure minima.

Abstract: An apparatus for separating particles from a medium includes a capillary defining a flow path therein that is in fluid communication with a medium source. The medium source includes engineered acoustic contrast capture particle having a predetermined acoustic contrast. The apparatus includes a vibration generator that is operable to produce at least one acoustic field within the flow path. The acoustic field produces a force potential minima for positive acoustic contrast particles and a force potential minima for negative acoustic contrast particles in the flow path and drives the engineered acoustic contrast capture particles to either the force potential minima for positive acoustic contrast particles or the force potential minima for negative acoustic contrast particles.

Abstract: The present invention provides a protein-based biomarker, ApoA-II isoform, that is useful in determining prostate cancer status in a patient. In particular, the biomarker of this invention is useful to classify a biological sample as prostate cancer or non-prostate cancer. The ability of ApoA-II to detect disease in patients with a normal prostate-specific antigen (PSA) makes the biomarker of this invention useful in identifying indolent disease. The biomarker can be detected by SELDI mass spectrometry, HPLC, PAGE and Western blotting.

Abstract: A process for preparing a crystalline, carbapenem monosodium salt of formula IIa: characterized by the steps a) adding about 10 to 30% of an organic solvent to an aqueous solution of the carbapenem, b) cooling the resulting solution to less than ?5° C., c) adjusting the pH using a solution containing an acid in an organic solvent to give the appropriate pH for crystallization, and d) crystallizing the compound by adding methanol, and a C2-5 alcohol at between ?5 and ?25° C.

Abstract: A fuel inerting system, comprising a first supply means (2) to supply an inert gas to a fuel tank (8) to scrub the fuel therein when the ullage (16) of the fuel tank is inert, and a second supply means (4) to supply the inert gas to scrub the fuel (6) therein when the ullage of the fuel tank is not inert, the first and second supply means (2, 4) being individually operable by means of a valve arrangement (10), in such a manner that only one of the supply means is operable at any given time. The inert gas consists of nitrogen enriched air, produced by passing air from a pressurised area of the aircraft through a nitrogen separator located within, but removable from, the aircraft.

Abstract: A rack for dispensing and storing spooled material. The rack has at least one platform for storing the spooled material, a support for maintaining the platform above the floor level, a pair of arms attached to the platform, and an axle for rotatably receiving the spooled material for dispensing there from. The axle is substantially horizontally supported by the arms away from a peripheral edge of the platform. In one embodiment, the arms include a plurality of notches for supporting the axle in one of a plurality of positions spaced from the platform. In another embodiment, the axle has one end pivotally attached to one of the arms and the other end received in a notch in the other arm.

Abstract: A method using quartz resonators probes dynamically the mechanical characteristics of thin films. This method probes the film properties at the anti-resonance frequency where the vibrational amplitude is smallest, minimizing nonlinear contributions in the dependence of the film mechanical characteristics on the resonator electrical characteristics. Determination of the mechanical characteristics involves impedance analysis, transformation of .vertline.Y.vertline. and .theta. data into a linear form so that the conductance and susceptance at the frequency of minimum absolute admittance can be accurately determined, and use of a two-dimensional Newton-Raphson numerical method to determine the values of the storage modulus G', loss modulus G", as well as various other film and resonator properties.

Abstract: A terminal capacitor cover assembly having a screw portion and a jacket portion for complementarily fitting a terminal for a capacitor. This assembly provides an easy retrofit for capacitor terminals to equip them with a aesthetically acceptable and functionally superior alternative material. The assembly can be constructed of material equivalent to the operatively connected electrical lead, thus reducing the anodization and cross metallic oxidation of the capacitor terminal.

Abstract: The invention relates to a piezoelectric biosensor device and also to a method and a system utilizing a piezoelectric biosensor device for detecting metabolic growth requirements, antibiotic responses, and the specific bacterial products of microorganisms. When a microorganism is grown in an appropriate nutrient medium containing a metabolic product responsive polymer, metabolic products of the organism acidify the medium and precipitate a polymer metabolic product complex which deposits or accumulates on the surface of a piezoelectric biosensor device. The mass change on the surface of the device resulting from this deposit produces a change in the resonant frequency of the piezoelectric biosensor device which can be used to determine the growth and type of microorganism.
