Abstract: A system and method for the detection and quantification of biomolecules by measuring a piezoelectric signal is described. The system comprises a plurality of elongate zinc oxide nanowires mounted generally parallel to each another on a semi conductive silicon substrate. The free ends of the nanowires are provided with biomolecules that are capable of associating with complementary biomolecules within a biological or water sample. Following incubation of the system in a sample, the association of molecules of interest with the immobilised biomolecules on the system results in the displacement of the zinc oxide nanowires. The displacement of the nanowires produces a piezoelectric voltage signal that is useful in diagnosing a pathogenic infection or the contamination of a sample.

Abstract: A method for measuring a surface tension of a liquid is carried out using an electrospraying apparatus connected in a system. A voltage source applies a voltage between a capillary through which the liquid is drawn and an electrode of the electrospraying apparatus. An ammeter continuously measures current flowing in the system and if no current or a current less than a predetermined threshold current is measured in the system, the strength of the electric field at the capillary is increased. As soon as current is measured in the system, a reading of a parameter of the system is taken, which is used to calculate the surface tension of the liquid.

Abstract: A multi-mode composite antenna is disclosed. The antenna includes at least two dipole elements, each dipole element having two arms with a signal transmission line connected to each arm, a conductive tube in which the signal transmission lines extend which forms a shield for the signal transmission lines, and an extension of the conductive tube. In one embodiment, the extension is formed by the conductive tube being folded back over itself. The dipole elements are capable of being excited by at least one differential mode excitation to realize a dipole radiation pattern, and the extension forms a monopole element with a monopole radiation pattern when at least one dipole element is excited by a common mode excitation. The composite antenna is capable of a combined monopole and dipole radiation pattern through the application of both differential mode excitation and common mode excitation.

Abstract: A packed rock bed thermal energy storage facility is provided in the form of a pile of unconstrained rock that is free to expand and contract with changing temperature without creating significant stress. A hot fluid inlet and outlet space is provided above the bed and a cold fluid inlet and outlet space is formed by a grid and larger rocks, or by larger rocks only, that support the pile toward a bottom of the bed. Fluid flow can occur downward through the rock bed during heating of the bed and upward through the rock bed during cooling of the bed in a heat recovery cycle. The bed is completely covered by an insulated arched roof. The rock bed may be an enclosure having a roof, walls and a floor with a lower central region and somewhat inclined side regions extending at a gentle slope towards sidewalls supporting the roof.

Abstract: The present invention is directed to a yeast strain, or strains, secreting a full suite, or any subset of that full suite, of enzymes to hydrolyze corn starch, corn fiber, lignocellulose, (including enzymes that hydrolyze linkages in cellulose, hemicellulose, and between lignin and carbohydrates) and to utilize pentose sugars (xylose and arabinose). The invention is also directed to the set of proteins that are well expressed in yeast for each category of enzymatic activity. The resulting strain, or strains can be used to hydrolyze starch and cellulose simultaneously. The resulting strain, or strains can be also metabolically engineered to produce less glycerol and uptake acetate. The resulting strain, or strains can also be used to produce ethanol from granular starch without liquefaction. The resulting strain, or strains, can be further used to reduce the amount of external enzyme needed to hydrolyze a biomass feedstock during an Simultaneous Saccharification and Fermentation (SSF) process, or to increase the yield of ethanol during SSF at current saccharolytic enzyme loadings. In addition, multiple enzymes of the present invention can be co-expressed in cells of the invention to provide synergistic digestive action on biomass feedstock. In some aspects, host cells expressing different heterologous saccharolytic enzymes can also be co-cultured together and used to produce ethanol from biomass feedstock.

Abstract: A machine having two co-axial and relatively rotatable rotors and a coaxial stator or housing with respect to which both rotors are rotatable is provided wherein two bearing arrangements mutually support the two rotors with respect to each other and with respect to the stator or housing. One of the bearing arrangements comprises multiple support bearings angularly spaced apart with respect to the axis of rotation of the rotors relative to the stator with the support bearings each having an axle or shaft that is fixed relative to one of the rotors or the stator. Each support bearing cooperates with a raceway provided on a concentric adjacent rotor or stator. The machine may be an electromechanical machine such as a wind turbine in which rotational movement of one of the rotors relative to the other and relative to the stator generates electrical energy.
