Abstract: Disclosed are methods of detecting an analyte of interest comprising introducing a sample comprising an analyte of interest to an antibody or antibody fragment; incubating the sample and antibody or antibody fragment under conditions sufficient to allow binding of the analyte of interest to the antibody or antibody fragment; and detecting the binding of the analyte of interest to the antibody or antibody fragment using a label-free second harmonic detection system. Also disclosed are methods of screening and diagnosing using antibodies or antibody fragments and a label-free second harmonic detection system.

Abstract: A device for applying drywall compound to a length of corner bead. The device comprises a trough for holding a quantity of drywall compound and an opening at the bottom of the trough through which a length of corner bead may be inserted. A removable block is located near an opening in the trough having a plurality of grooves located therein for preventing excess drywall compound from adhering to the bead while allowing sufficient compound to remain with the bead. A flange attached to the top of the trough is adapted to be attached to a bucket, the bucket having a portion of the bottom removed, to provide drywall compound to the trough.

Abstract: A wallboard tape including a paper tape having two outer edges. At least one pair of raised beads are adhered to the tape and extend parallel to the outer edges of the tape. The beads may optionally be formed on the tape from a hot melt adhesive and optionally have a generally arcuate top surface. At least one polyvinyl chloride stiffening strip may optionally be adhered to the tape with a hot melt adhesive and a protuberance on the side of the tape opposite the beads and running the length of the tape near the center of the tape also may optionally be applied.

Abstract: A method of making wallboard including the steps of providing an unfinished length of wallboard that has a recess along its longitudinal edges by conveying it upon a conveyor in a first direction in a step, forming recesses in the unfinished length of wallboard at both lateral edges thereof, selecting an apparatus for forming the recess from a plurality of device for forming the recess, forming the recess with the selected apparatus, and separating the unfinished length of wallboard at a location of the recess to form finished lengths of wallboard, such that the finished lengths of wallboard have recessed lateral edges. Also disclosed is a system for performing the method.

Abstract: A corner bead for joining adjacent pieces of wallboard including an arched center section having a pair of wing sections attached thereto. The arched center section extends outwardly above planes defined by the wing sections, and the wings and arched center section define an interior surface which is placed adjacent the wallboard and an exterior surface which is placed opposite the wallboard. A reinforcing member is disposed adjacent the interior surface of the arched center section and attached thereto to provide rigidity to the arched center section.

Abstract: A lipid membrane is self-assembled and stabilized at a solid surface by depositing a lipid monolayer or a lipid multilayer on a substrate, otaining a supported lipid monolayer or a supported lipid multilayer; and in situ polymerizing the supported lipid monolayer or the supported lipid multilayer, thereby obtaining a polymerized membrane.
