  • Patent number: 8586068
    Abstract: The present invention utilizes a fatty acid as an attractant in a method of attracting whiteflies. By using a fatty acid as a whitefly attractant, it is possible to attract whiteflies to a desired location. The fatty acid can be used in a lure or other propagator to provide a dispersion of fatty acid in the air, the variation in the concentration of the fatty acid in the air being such that a whitefly is attracted to the lure as the source of the fatty acid. The use of a fatty acid as an attractant results in significantly higher levels of attraction, as measured by the number of whiteflies attracted to a sticky trap, as compared to the use of color alone.

  • Publication number: 20090123366
    Abstract: In order to target a diseased material in a subject, a monocyte, or monocyte-derived cell, such as a macrophage, which incorporates a magnetic material, such as a magnetic particle or a ferrofluid, preferably having a biocompatible coating, is proposed to be administered. A magnetic energy source may then be applied to the subject to destroy, rupture or inactivate the diseased material. Alternatively, the monocyte or monocyte derived cell may additionally include a therapeutic agent, which is thereby targeted at the diseased material.

  • Patent number: 6328737
    Abstract: A fracture reduction device comprises linear adjustment means for linearly reducing a fractured bone in three directions, and angular adjustment mechanism for angularly reducing a fractured bone about three independent axes. The adjustment mechanism is such that adjustment in each direction and about each axis is independent of the others. The device also allows stable incremental adjustments to be made to the bone position and/or orientation.

  • Patent number: 5827620
    Abstract: Solid oxide fuel cell structures which are capable of relatively rapid temperature changes without cracking and which are simple to seal. In one arrangement, a tubular SOFC structure comprises a self-supporting extruded tube of zirconium oxide with inner and outer electrodes. The tube may have an outside diameter of from, for example, 1 to 5 mm and a wall thickness of from, for example, 50 to 200 microns. In an alternative arrangement, a simple gas type planar interconnect for a planar SOFC is provided in the form of a sheet of ceramic material having electrically conducting bodies of ceramic material embedded in it so as to provide an electrical path through the sheet. To avoid edge sealing problems, fuel gas and air may be delivered to a stacked SOFC structure through tubes extending between adjacent cell sub-assemblies such that the gas is delivered to a central portion of each anode of the cell stack and flows outwards towards the edges of the stack.

  • Patent number: 5629474
    Abstract: A sensor to detect gases and vapors, particularly carbon monoxide and water vapor, at relatively low concentrations includes a substrate having a layer on a face of the substrate. The layer comprises a semi conductor metallic oxide (such as stannic oxide), a catalyst (such as platinum black), and a rheological agent (such as kieselguhr or sepiolite). The rheological agent induces porosity into the surface of the layer. The rheological agent affects the mixing and processing of the layer, and aids binding, resulting in a sensor with greater sensitivity and faster response.
