Abstract: A method of detecting subsurface conditions conducive to fluid transfer can include obtaining microseismic resonance signals from multiple surface locations over a subsurface region of interest using a resonance sensor, wherein for at least a plurality of the multiple surface locations, multiple microseismic resonance signals are obtained at different times to generate signal stacks. In some examples, the method can also include amplifying the microseismic resonance signals, filtering out the high frequencies at least above about 7,500 Hz leaving low frequencies at least as low as about 4 Hz for evaluation, and using these low frequencies to identify subsurface fracture zones where subsurface fluid may be present. In some examples, subsurface fluids can be detected and/or mapped using gamma radiation count and/or magnetometric density data collected using appropriate equipment.

Abstract: A system for detecting a location of a subsurface channel may include a portable frame and a plurality of magnetic coils supported by the frame. The magnetic coils may be spaced apart from one another and ends of each of the magnetic coil are unobstructed by other of the magnetic coils.

Abstract: A method of modeling a subsurface hydrogeologic system within a study area can include applying an electric current directly to the subsurface hydrogeologic system and monitoring a magnetic field generated by the electric current in the subsurface hydrogeologic system. An electric current distribution can be identified within the study area by an inversion process based on the magnetic field. A model of the electric current distribution can be created.

Abstract: A system for holding poured concrete in a desired shape until it sets is disclosed. The system can include a plurality of forms having two opposing end sections. Each of the end sections has an end bracket attached to it. A plurality of footing stakes are used to connect the end brackets together such that the forms maintain the desired shape. At least one whaler bracket may be secured to a top of the forms to maintain the spacing between them. A skin panel can be used to bridge gaps between forms. Bulkhead brackets can be attached to the ends or centers of the forms and secured to allow end walls to be created where desired. Vertical footing panels can also be used to pour concrete onto adjoining inclined surfaces.

Abstract: The pipette tip packaging and transfer system comprises a plurality of receiving plates and a transfer member. Each receiving plate includes a plurality of openings for receiving pipette tips in a substantially vertical alignment at a medial position thereof. The loaded receiving plates can be stacked one atop of another with the pipette tips contained within a first receiving plate being received in the top openings of the aligned pipette tips contained within the underlying receiving plate of the stack. The transfer member has a plurality of projections extending from the bottom surface of the transfer member at positions that correspond to the location of the openings of the receiving plate. The projections are configured and arranged to extend into the top openings of the pipette tips on the upper-most receiving plate and maintain the pipette tips in a fixed and substantially perpendicular alignment in relation to the transfer member and receiving plate.

Abstract: A method and apparatus (10) for detection of the degree of cure of a polymer in situ and non-invasively. The method and apparatus uses a solvatochromic probe molecule which upon curing produces a shift in the fluorescence emission spectrum as compared to a liquid polymerizable composition. The method and apparatus is particularly adapted for poly(vinyl) polymers. Preferred solvatochromic probe molecules are oxazones and pyrene.
