Abstract: Embodiments relate to noncontact determination of nonlinearities. Initially, a first and second primary signal are preconditioned to produce a first and second tone capable of reaching a target granular media. Using a sound source, the first and second primary signals are emitted such that the first and second primary signals combine in a nonlinear fashion in the target granular media to produce low frequency acoustic tone that is a difference between the first and primary signals. An acoustic pulse is received by an acoustic receiver, and a quadratic nonlinearity coefficient and an acoustic pressure field are determined based on the acoustic pulse. At this stage, a sediment shear strength of the granular media is correlated to the quadratic nonlinearity coefficient to generate a shear strength lookup table.

Abstract: The disclosed subject matter generally relates to methods and apparatus for coating opposing sides of a substrate simultaneously with a coating material. The disclosed subject matter also generally relates to apparatus for simultaneously applying a coating material to multiple sides of the substrate.

Abstract: Embodiments of the invention relate to methods and systems for the detection of Mycobacterium tuberculosis. Mycobacterium tuberculosis kills more than one million people each year. To better understand why M. tuberculosis is virulent and to discover chemical markers of this pathogen, we compared its lipid profile to that of the attenuated but related mycobacterium, Mycobacterium bovis Bacille Calmette Guerin (BCG). This strategy identified previously unknown compounds that are specific to M. tuberculosis, e.g. 1-tuberculosinyladenosine, N6-tuberculosinyladenosine, and various tuberculosinyladenosines having mycolic acids, produced by the Rv3378c enzyme.

Abstract: Apparatus and methods for testing sediment submerged in liquid and manufacturing the apparatus. The apparatus and methods of the present embodiment can provide for nano/micro characterization of mechanical properties of materials submerged in liquid, facilitating specimen preparation and installation, and can provide hydrated materials. The apparatus can include cell walls with optical magnifying lenses so that the materials can be viewed without the aid of a microscope.

Abstract: A cover is disclosed for a pickup truck bed with the cover being comprised of upper and lower metal sheet members secured at their edges to define a compartment therebetween which is preferably filled with a foam strengthening material. Preferably, the sheet members are constructed of an aluminum material.

Abstract: A truck lid hinge and opener system for removably connecting a lid or cover to the bed of a truck wherein the bed includes a vertical front wall, first and second vertical side walls extending rearwardly from the front wall, and a tailgate at the rearward end of the bed with the side walls having downwardly extending flanges at the upper end thereof. A pair of hinge units removably hingedly connect the forward end of the lid to the truck bed. A pair of like opener mechanisms pivotally interconnect the sides of the lid to the side walls of the truck bed. Each of the open mechanisms includes a gas spring which is adjustably mounted to compensate for varying temperature conditions. The hinge units and opener mechanisms are clamped onto the truck bed to avoid drilling holes in the truck bed.
