Abstract: A rack system for housing electronic and/or electrical equipment is provided comprising a rectangular base frame, a rectangular top frame, and four elongated vertical support members each extending along a longitudinal axis between and joined to two associated corners of the rectangular base frame and the rectangular top frame. The rectangular base frame, rectangular top frame, and the four elongated vertical support members may be constructed from members having the same substantially A-frame cross-section. Each support member may be constructed from an elongated sheet material extending along a longitudinal axis by bending the sheet material about an axis parallel to the longitudinal axis of the sheet material to form at least three elongated sections, where a first section and a second section are adjacent and substantially perpendicular to each other and a third section extends between approximately mid-point of the first section and approximately mid-point of the second section.

Abstract: The invention provides a method for controlling insects of the Order Diptera by providing a Bacillus thuringiensis strain or variant thereof, or a spore or crystal of the Bacillus thuringiensis strain or variant thereof, and either contacting the insect with or administering to an animal the Bacillus thuringiensis strain or variant thereof, or the spore or crystal of the Bacillus thuringiensis strain or variant thereof; or applying the Bacillus thuringiensis strain or variant thereof, or the spore or crystal of Bacillus thuringiensis strain or variant thereof to an infested area. The Bacillus thuringiensis strain contains a plasmid carrying endotoxin genes for encoding delta-endotoxins Cry1A, Cry1B, Cry1F, Cry1H, Cry1I, Cry1K, Cry2 or a variant thereof. Preferably, the strain is Bacillus thuringiensis strain LRC3 deposited as ATCC PTA-6248. Methods for preparing the strain, spores, crystals, mutants, variants, and compositions incorporating same are described.
