    摘要: A surface-enhanced Raman spectroscopy (SERS) substrate formed from a plurality of monolayers of polyhedral silver nanocrystals, wherein at least one of the monolayers has polyvinypyrrolidone (PVP) on its surface, and thereby configured for sensing arsenic is described. Highly active SERS substrates are formed by assembling high density monolayers of differently shaped silver nanocrystals onto a solid support. SERS detection is performed directly on this substrate by placing a droplet of the analyte solution onto the nanocrystal monolayer. Adsorbed polymer, polyvinypyrrolidone (PVP), on the surface of the nanoparticles facilitates the binding of both arsenate and arsenite near the silver surface, allowing for highly accurate and sensitive detection capabilities.

    摘要: A tractor drawn and powered machine is disclosed for forming large round bales of fibrous agricultural crops in a chamber of fixed size. The baling chamber consists of a lower and an upper section. The lower section includes a wheel mounted main frame, along with a pickup reel and a bottom conveyor comprising side by side belts entrained on four transversely extending rollers. The upper section is supported on a subframe which is hinge mounted along its front edge to the main frame allowing thereby the rear portion of the upper section to open as a rearward facing tailgate for discharge of a completed bale. Situated within the subframe of the upper section are all of the conveying elements which make up the rear, top and front of the generally cylindrical periphery of the baling zone. Each conveyor element in the upper section comprises a plurality of side by side belts entrained on spaced apart transversely mounted upstream and downstream rollers. A space between the last of the serially arranged conveying elements and the uppermost surface of the bottom conveyor provides an inlet into the baling chamber. During the bale forming operation a latch mechanism holds the tailgate closed. When a bale is ready for discharge the tractor is halted, the tailgate is opened by a hydraulic cylinder and the bale is conveyed out the rear of the machine. As soon as the bale falls to the ground, the tailgate can be reclosed making the machine ready for pickup of more crop material with which to form another bale.

    摘要: A mirror includes an electro-optic mirror subassembly, and a thin-profiled bezel attached around a perimeter of the electrochromic mirror subassembly. The electro-optic mirror subassembly is supported on a carrier by an adheringly bonded heater and foam tape in a laminar arrangement. The bezel may be bonded to an edge of the front surface of the front element of the electro-optic mirror subassembly, and/or may be bonded and/or interlockingly mechanically attached to an edge of the carrier. Alternatively, the bezel can be a strip of paint or thin coating material. The bezel can be molded in place, or can be pre-molded and elastically stretched to permit assembly. In one form, the bezel includes a laterally-extending fin that prevents seeing past the bezel into the inside of a mirror housing. In at least one embodiment, the assembly has no bezel or only a bezel on one edge.

    摘要: Public records are used to help in the detection and prevention of fraud as well as to verify a consumer. Public records are accessed in real-time and then used to determine if a consumer is who they claim to be or is a fraudster. Questions are generated using the public records based on an initial fraud score and a verification level associated with the entity requesting the fraud and verification services. Based on the response to the questions, the fraud score is updated and a confidence level is returned to the requestor to determine whether the user is legitimate or a fraudster. The questions may be presented online or offline. The verification can be different for every merchant.

    摘要: A cap for a flue opening of a chimney in order to enhance draw of smoke and in order to protect from entry of animals, debris, and the elements. The device includes a tubular housing having sidewalls fabricated from flat sheet metal and a top attached to the sidewalls from fasteners. A plurality of louver openings are provided in the sidewalls in order to draw air. A plurality of exit vent openings in the sidewalls above the louver openings are at least equal to a cross-sectional area of the flue opening. An inner frame and mounting assembly includes a mechanism to both anchor the device to the chimney flue and to level the device.
