Abstract: The disclosed technology generally relates to integrated circuit devices with wear out monitoring capability. An integrated circuit device includes a wear-out monitor device configured to record an indication of wear-out of a core circuit separated from the wear-out monitor device, wherein the indication is associated with localized diffusion of a diffusant within the wear-out monitor device in response to a wear-out stress that causes the wear-out of the core circuit.

Abstract: A wastewater treatment system and method for substantially reducing or eliminating total suspended solids (TSS), biological organic discharge or biochemical oxygen demand (BOD), and fats, oils and greases (FOG) contaminants. The system includes at least one mixing chamber for mixing wastewater with at least one dewatering agent or chemical and air to form an aerated mixture and at least one tank having a plurality of compartments for facilitating flotation, settling and removal of contaminants from the aerated mixture as it flows through the tank. Preferably, the system includes first and second mixing chambers and first and second tanks arranged in series with each of the tanks including drag lines for removing floating and settled contaminants.

Abstract: A method for compaction of iron bearing materials includes the steps of accumulating iron and steel plant waste materials, including iron bearing fines, hazardous mill waste products, fines, turnings, borings, sludge, dust, mill scale, and the like; and agglomerating such materials by ram briquetting in a ram briquetter.

Abstract: This invention relates to a method and apparatus for reducing iron oxide to metallic iron, utilizing a continuous process employing a reducing gas with high hydrogen and carbon monoxide content made by a catalytically reforming mixture of hydrocarbons, reacted off-gases from the reduction process and steam generated from waste heat from the process and or flue gases. Carbon dioxide and water vapor present in the reacted off-gas is utilized as a hydrocarbon reforming oxidant. Steam generated from waste heat from process and/or waste flue gas is also used as a hydrocarbon reforming oxidant. The steam injected into the process gas stream is also used to control the hydrogen-carbon monoxide ratio required for efficient reduction of iron oxide to metallic iron.
