    摘要: Compositions and methods for protecting a plant from an insect pest are provided. In particular, nucleic acid sequences encoding insect protoxins modified to comprise at least one proteolytic activation site that is sensitive to a plant protease or an insect gut protease are provided. Cleavage of the modified protoxin at the proteolytic activation site by a protease produces an active insect toxin. Methods of using the modified insect protoxin nucleic acid sequences and the polypeptides they encode to protect a plant from an insect pest are provided. Particular embodiments of the invention further provide modified insect protoxin compositions and formulations, expression cassettes, and transformed plants, plant cells, and seeds.

    摘要: A niobium-based superconductor is manufactured by establishing multiple niobium components in a billet of a ductile metal, working the composite billet through a series of reduction steps to form the niobium components into elongated elements, each niobium element having a thickness on the order of 1 to 25 microns, surrounding the billet prior to the last reduction step with a porous confining layer of an acid resistant metal, immersing the confined billet in an acid to remove the ductile metal from between the niobium elements while the niobium elements remain confined by said porous layer, exposing the confined mass of niobium elements to a material capable of reacting with Nb to form a superconductor.

    摘要: Porous metal compacts suitable for use as electrodes are formed through the reduction of a metal billet consisting of multiple filaments of an appropriate valve metal, preferably tantalum, contained within, and spaced apart by, a ductile metal, preferably copper. The filaments are elongated and substantially parallel within the billet. The array of valve metal filaments within the billet is surrounded by a continuous layer of valve metal. This metal is preferably, but not necessarily, the same as that which forms the filaments. The valve metal layer preferably completely surrounds the filament array circumferentially and runs the full length of the filaments. The layer is separated from the array by the same ductile metal that serves to separate the filaments from each other. This same ductile metal forms the surface of the billet, preventing exposure of the valve metal layer. The billet is reduced by conventional means, such as extrusion and wire drawing, the composite product is cut into short lengths, and the ductile metal separating the valve metal components of the composite is removed, preferably by leaching in mineral acids. The filaments are constrained within the valve metal tube, making handling during subsequent capacitor manufacture much less difficult than if the filaments were allowed to move freely.

    摘要: In the present invention, a superconductor is produced by the steps of wrapping a plurality of layers of metal sheets around a support to form a composite structure. The sheets are pure transition metals-13 niobium, titanium, zirconium, or vanadium, for example--alternate sheets being formed of different transition metals. The support may be composed of any ductile metal. The resulting composite structure is mechanically reduced sufficiently so that each transition metal sheet is less than 1000 .ANG. thick. In the course of reduction, the composite is subjected to sufficient temperatures for sufficient times such that the transition metal layers are partially reacted to form a ductile superconducting material between the transition metal layers. Approximately one half by volume of the transition metal layers remain unreacted. These unreacted layers afford efficient flux pinning within the composite when the layers are reduced to the
