Abstract: Systems and methods using the properties of supercritical water to allow raw air including a contaminant to be combined with water and to be purified in a supercritical water oxidation (SCWO) process. A supercritical water oxidation (SCWO) air purifier will generally take in a mixture of water and raw air which includes oxygen via a pumping and mixing apparatus, put the mixture into a supercritical water reactor (SCWR), and run the resultant effluent stream through a system for separating the water from the resultant clean air and the other relatively harmless outputs of the supercritical water reactor (SCWO).

Abstract: Systems and methods are provided for operating a pulse width modulation (PWM) circuit in a direct current (DC) to alternating current (AC) power inverter to reduce the magnitude of harmonics. The PWM circuit operates using a reference signal having an irregular period. In one implementation the irregular periodicity includes a sequence of periods uniformly distributed about a target period.

Abstract: An energy efficient electrical power generator has a primary energy conversion mechanism, such as an internal combustion engine, and a secondary energy conversion mechanism, such as a thermoelectric device. The secondary energy conversion mechanism increases the electrical power output and efficiency of the generator.

Abstract: A piping transport structure for use with a deployment vehicle to provide for improved efficiencies in laying temporary or semi-permanent piping structures. There is also a system for having one or more deployment vehicles smoothly lay piping and to allow for long pipe lays to be carried out in less time.

Abstract: A filtration unit for use with an environmental control unit (ECU), usually a portable ECU, which includes at least two air flow paths wherein at least one of the air flow paths allows for use of air which has not passed through a nuclear, biological, and chemical (NBC) filter and at least one other does. The filtration unit may have at least three air paths, at least two of which provide NBC filtered air. This filtration unit can provide for longer expected operational life before filter replacement is required in both contaminated and non-contaminated environments. Further, the filtration unit may include remote sensing and control apparatus allowing for quick switching between operational modes depending on the need for filtered vs. unfiltered air and for a decreased reliance on personnel for maintenance and control, and a more simplified setup.

Abstract: Methods for using supercritical water to convert hydrocarbons, particularly hydrocarbon fuels such as diesel fuel, jet fuel, or gasoline, into carbonaceous gases and hydrogen. The synthesis gas stream generated by the fuel reforming reaction can then be further refined to increase hydrogen content, and the resultant hydrogen can be utilized to power fuel cells.

Abstract: Apparatus and a method of controlling operation of a wide variety of appliances so the appliance can only be used by an authorized individual, and then only under certain specified conditions. The apparatus and method provide safe use of the appliance since presumably the person authorized to use the appliance is trained in its use, and where circumstances warrant, knows how to use the appliance safely. It is a particular advantage of the invention to prevent unsafe use of the appliance, even by an authorized user.

Abstract: A 15 kDa selenium-containing protein (“selenoprotein”) is disclosed. The protein is shown to be differentially expressed in cancer cells, such as prostate cancer cells. There is a correlation between the presence of a polymorphism at nucleotide positions 811 and 1125 of the 15 kDa selenoprotein gene, and the presence of cancer. This polymorphism is more prevalent in the African American population. The determination of an individual's genotype may be used as an indicator of the need for dietary selenium supplementation to inhibit tumor development. Compositions including the isolated protein, specific binding agents that recognize the protein, as well as underlying nucleic acid sequences are presented, as are methods of using such compositions.
