Abstract: A modular reusable catalyst system is provided for a bi-propellant rocket engine and adaptable for a monopropellant, wherein a hydrocarbon fuel is combined with one or more catalysts, and can provide an additional convergent-divergent flow in combination with a thruster.

Abstract: A medical/veterinary procedure simulation apparatus includes a simulated mammalian body part. The simulated mammalian body part further includes one or more anatomical replications of mammalian tissue. The apparatus also includes an attaching substrate for fixedly attaching the simulated body part to a mammal or a model of the mammal. The apparatus further includes one or more sensors configured to provide a quantified measurement of one or more actions, pertaining to at least one medical procedure. The apparatus further includes a virtual reality system configured to receive one or more input signals from the one or more sensors. The virtual reality system is further configured to display at least one visual representation of at least one clinical procedure being performed on the one or more anatomical replications based on the one or more input signals from the one or more sensors.

Abstract: Methods for the remediation of environmentally damaged articles includes removably positioning a conversion door having a height-adjustable header assembly and a plurality of access ports with respect to an access opening of a storage container so as to close the access opening with the container door in an opened condition, and connecting at least one of the access ports with remediation equipment to permit remediation of environmentally damaged articles within the interior chamber of the container. The header assembly is adjustably moved relative to an upper edge region of the conversion door so as to permit vertical height adjustment thereof and fit the conversion door with respect to a vertical dimension of the access opening.

Abstract: A convertible storage container and methods are provided for the remediation of environmentally damaged articles. The container defines an interior chamber for receiving the environmentally damaged articles therein, the container having at least one container door for closing an access opening into the container. A conversion door is removably positionable with respect to the access opening so as to close the access opening with the container door in an opened condition. The conversion door includes a conversion door panel and a plurality of access ports through the door panel for connection of ducts to permit remediation of the environmentally damaged articles within the interior chamber.
