Abstract: The invention is a water recovery system that utilizes waste heat and a moving air stream to recover water with minimal use of energy and without the need to move water through filtration devices. The invention may be used for recovery and reuse of water for a wide range of emergency back-up, environmental, industrial, and mission-oriented purposes.

Abstract: A recombinant Moringa oleifera coagulant protein (MO) produced and secreted by Bacillus has coagulation/flocculation activity. The MO protein and the Bacillus host cells expressing the MO protein can be used in compositions and methods for treating contaminated water, such as drinking water or waste water. The MO protein can coagulate or flocculate suspended solid impurities in the water, which can then be removed.

Abstract: The present invention is a self-regenerating biofilter. The biofilter tank receives untreated water through an intake inlet, filters it through a filtration mass and expels purified water through an output outlet. The filtration mass includes gravel and activated carbon layers separated by a mesh screen. A compressed air line is located below the mesh screen. Periodically, the biofilter self-cleans by opening a flush valve that expels a flush water stream carrying debris. The biofilter self-regenerates by periodically stopping filtration for a time, allowing biological matter left on the activated carbon to degrade into biomass. Periodically, the biofilter removes and flushes out biomass by application of water or a combination of air and water.

Abstract: The present invention is an ammonia sequestering system including a system controller connected to a plurality of flow control valves, a feed stream extending through a system inlet, and a system outlet. The feed stream is a liquid contaminated with ammonia. At least one exchange column is located between the system inlet and the system outlet. The ion column includes an ion exchange material, a column inlet connected to one of the flow control valves, and a column outlet connected to another of the flow control valves. The system also includes a regenerant stream of an aqueous solution of sodium cations, as well as an ammonia brine stream made up of the regenerant stream and ammonia.

Abstract: The invention relates to methods and a kit for the diagnosis of endometriosis. More particularly, the invention relates to the measurement of endometrial leukocytes bearing CD16b and, optionally, other leukocyte or serous markers, for determining likelihood of suffering from endometriosis in a female subject.

Abstract: An audio level dynamic range compression circuit 1 comprises a variable gain amplifier 6, an audio signal level averaging stage 8, an analog-to-digital converter 10, and a digital processor 12. The output from the averaging stage 8 is passed to the analog-to-digital converter 10 which has as its output a digital value representative of the level of the averaged audio signal. This digital value is then passed to the digital processor 12 which processes the digital value relative to a predetermined level of the averaged audio signal to produce a gain control output which varies in response to the digital value and which is passed to the variable gain amplifier 6 in order to compress the dynamic range of the output audio signal when the digital value is above the predetermined level. The gain control output is more rapid when the level of the averaged audio signal is rising than when the level of the averaged audio signal is falling.
