14. Title: Process and System for Treating Waste From the Production of Energetics. A waste stream from energetics processing is treated using a pre-filter having media, preferably sand, and a metal that has a reducing potential, preferably elemental iron (Fe0). The pre-filter is connected to a zero-valent metal column reactor. The waste stream is pumped through the pre-filter to trap solids and deoxygenate it, then enters the reactor and is subjected to a reducing process. Most of the Fe2 is transformed to the ferrous ion (Fe+2), added to the resultant products, and fed to a continuous stirred tank reactor (CSTR) in which Fenton oxidation occurs. This product is then sent to a sedimentation tank and pH-neutralized using a strong base such as sodium hydroxide (NaOH). The aquesous portion is drawn off and the sludge pumped from the sedimentation tank. Both tanks are monitored and controlled to optimize required additives, while monitoring of pressure drop across the pre-filter and column reactor establishes replacement requirements.

15. Title: Reactive Geocomposite for Remediating Contaminated Sediments. In one application for remediating sediments, employing a geocomposite sheet eliminates the need for a thick cap or removal and subsequent ex situ treatment of the sediment. A geocomposite with at least one layer of reactive material is placed over the area to be remediated. A layer of available surcharge materials such as sand, gravel, or riprap covers the geocomposite. The weight of the surcharge materials causes pore water to flow from the sediment through the reactive layer or layers of the geocomposite. Contaminants may be trapped in this reactive layer or layers. A top or bottom layer, or both a top and bottom layer, may be provided to inhibit incursion from outside the sediment layer, while permitting appropriate flow direction or pore water into the reactive layer or layers.

16. Title: System and Method for Determining Status of an Object by Insonification. A flexible piezoelectric-based transducer, mounted on a circumference of a rotating object senses acoustical energy traversing portions of the object. In a preferred embodiment, the transducer is affixed, using a suitable adhesive, within the enclosed portion of a wheel/tire assembly. The transducer sense acoustical energy, e.g., ultrasonic transmissions, generated by the tire contracting the road surface at its contact patch and, without need of external power, translates it to an electrical current and communicates it for further processing. Because the acoustical impedance of the tire casing changes with temperature, hot spots within the tire, as well as other characteristics of the tire's operation, can be detected. Further, any Doppler shift, which occurs due to the rotating medium may be compensated for since the rate of tire rotation may be made known via a speed sensor. A position sensor may also be employed to indicate the position of the hot spot.
