Abstract: According to one embodiment, a first engaging surface can be configured to engage a first region of an antler set, and a second engaging surface can be configured to engage a second region of the antler set. A support structure can support the first and second engaging surfaces. The support structure can be configured to adjust a distance between the second engaging surface and the first engaging surface to inhibit shrinking of a distance between the first and second regions of the antler set.
Abstract: An apparatus and method for removing mercury, and in particular elemental mercury, from a fluid stream by exposing the fluid stream to a polyethersulfone or filter-coated with anion exchange resin, or anion exchange resin-coated surface onto which has been loaded elemental iodine. Elemental iodine is loaded onto the PES or anion exchange resin-coated surface by immersing the PES or anion exchange resin-coated substrate in an iodine/pentane solution, then removing the substrate from the iodine/pentane solution and rinsing in pentane.

Abstract: A method of analyzing a fluid sample by XRF includes the steps of: depositing the fluid sample onto a substrate, exposing the sample and the substrate to an x-ray emission, generating a first analytical signal responsive to the x-ray emission, providing an operable first reference material having a first extended position above the substrate and in communication with the x-ray emission, periodically extending the first reference material to its first extended position, generating a first calibration signal, providing an operable second reference material having a first extended position below the substrate and in communication with the x-ray emission, and periodically extending the second reference material to its first extended position and generating at least one second calibration signal. The first and second calibration signals are compared with predetermined values. The first and second reference materials also have second retracted positions.

Abstract: A method for removing mercury, and in particular elemental mercury, from a fluid stream by blending the fluid stream with a second stream comprising iodine. The blended stream is then passed through at least one filter, which is capable of removing oxidized forms of mercury from gas streams.
