Abstract: A ground-penetrating radar device comprises a frame, a radar antenna, and an antenna assembly, wherein the antenna is part of the antenna assembly. Further the GPR device comprises a mount for adaptively mounting the antenna assembly to the frame and a ground support for supporting the frame on the ground. In an operational state, the mount prevents a horizontal displacement of the antenna assembly relative to the frame in two horizontal directions. In the operational state, the mount further allows a vertical displacement of the antenna assembly relative to the frame and a tilting of the antenna assembly relative to the frame.

Abstract: A method and a device for probing a subsurface structure. The method includes sending an electromagnetic wave into the structure, receiving an echo of the electromagnetic wave from the structure and processing the echo for deriving an internal feature of the structure. The sending the electromagnetic wave into the structure includes subsequently sending a plurality of electromagnetic probe signals with differing frequency spectra into the structure. Each probe signal includes at least two non-zero spectral components. The receiving the echo includes receiving an echo signal for each probe signal. The processing the echo includes determining at least one amplitude and phase for each echo signal.

Abstract: Disclosed herein are embodiment relating to a methods of obtaining a functionalized porous or fibrous solid substrate with the chemical and/or physical properties of a nano-structured molecular or polymer chemical compound that contains it. In accordance with some example embodiments, the properties of the starting substrate may be modified to obtain a new functionalized substrate. The new substrate may have various applications, such as, for example, an optical- and/or fluorescent-type chemical sensor, as a chemical sequestrator, or as a modifier of the properties of a surface, making it, for example, superhydrophobic.

Abstract: A method and device for improved efficiency in thermal oxidation is presented which uses a cyclonic flame to combust a stream of hydrocarbons drawn to the flame source by a pressure differential. The improved burner and method are particularly suited for combusting volatile organic compounds that are a derivative result of another waste management process mechanically attached to a thermal oxidizer. The improved burner is formed by configuring a burner basket into a conical shape with openings that allow a combustible gas to travel along the interior of the basket frame. The gas travels spirally within the basket frame as it is assisted by forced air and when ignited, creates a cyclonic flame effectively combusting material such as volatile organic compounds that are manipulated into contacting the flame.

Abstract: An apparatus for aerating polluted water is disclosed herein. The apparatus includes a tubular section defining a primary chamber having an opening in the side for admission of air from the surrounding atmosphere. A principle distribution chamber for receiving water to be aerated is connected to an upper peripheral edge of the tubular section and delivers water to a plurality of high speed nozzles that deliver accelerated sprays into the primary chamber. A tapering section is connected to a lower peripheral edge of the tubular section. A venturi section is connected to the lower peripheral edge of the tapering section. A single drain pipe including an upper peripheral edge is connected to a lower peripheral edge of the venturi and constitutes the sole outlet of the device. The nozzles create an air water mixture in the primary chamber and are directed toward the venturi to create a suction effect thereby drawing additional air into the primary chamber through the inlet orifice.
