摘要:
The present invention provides methods and systems for nanowire alignment and deposition. Energizing (e.g., an alternating current electric field) is used to align and associate nanowires with electrodes. By modulating the energizing, the nanowires are coupled to the electrodes such that they remain in place during subsequent wash and drying steps. The invention also provides methods for transferring nanowires from one substrate to another in order to prepare various device substrates. The present invention also provides methods for monitoring and controlling the number of nanowires deposited at a particular electrode pair, as well as methods for manipulating nanowires in solution.

Configurations and methods are provided in which a bottom head is coupled to a coke vessel via a conveyor and an elevator such that the elevator moves the bottom head vertically relative to the coke vessel, and the conveyor moves the bottom head along a curved path. Contemplated configurations are especially advantageous where a coke vessel deheading device has a hinged or swing-away head and wherein the head and the vessel have a close-fit diametrical tolerance fit.

A deheader valve is fitted onto an existing or new coke drum by initially positioning the body and valve, and then raising the valve to mate with the flange using a lifting device other than a chain fall. The vertical positioning of the deheader valve is preferably accomplished with a hydraulic or pneumatic piston, winch, scissor jack, ratchet jack, screw jack, and so forth. The distance traveled by the valve using these devices is more than 2 cm, commonly at least 20 cm, and in some installations up to 40 cm or more. In retrofit situations an oil inlet is provided in a side wall of the drum above the bottom drum flange.

Methods for the diagnosis of visceral, cutaneous and canine leishmaniasis in a subject suspected of being infected with the parasitic protozoa Leishmania is disclosed. Disclosed are antibody-capture enzyme-linked immunosorbent assays (ELISAs) for the detection of antibodies to Leishmania parasite soluble antigens and antigen-capture ELISAs for the detection of Leishmania parasite soluble antigens in host samples. Also disclosed are immunodiagnostic kits for the detection of Leishmania parasite circulating antigens or IgM and IgG antibodies in a sample from subject having visceral, cutaneous or canine leishmaniasis. In these methods and kits, detection may be done photometrically or visually. The methods and kits also allow the visualization of Leishmania amastigotes or promastigotes in a sample.
摘要:
A dental care device for selective use as a toothbrush or a dental floss source. The device comprises an elongate body, wherein the body defines cavity used as a dental floss reservoir, a brush element proximal to a first end of the body, a floss egress aperture at a second end of the body. The brush element including a plurality laterally extending bristle members. The body includes a window element for enabling visual inspection of a dental floss remaining in the reservoir. A dental floss source includes a spool of dental floss mounted within the reservoir such that dental floss can be drawn from the spool.
