摘要:
Methods and systems for evaluating a material sample is provided. The system includes a material sample holder including a first flange having an aperture therethrough, a second flange having an aperture therethrough, the first and second flanges configured to frictionally hold a material sample sandwiched therebetween, a waveguide coupled to a first end of each of the first flange and the second flange, each waveguide configured to direct electromagnetic waves through respective apertures, a waveguide adapter communicatively coupled to a second end of each waveguide, and a control unit electrically coupled to the wave source, the control unit configured to control the waveguide adapter to transmit and receive electromagnetic wave signals.

A method of characterizing a nucleic acid sample is provided that includes the steps of: (a) conducting a DNA polymerase reaction that includes the reaction of a template, a non-hydrolyzable primer, at least one terminal phosphate-labeled nucleotide, DNA polymerase, and an enzyme having 3′→5′ exonuclease activity which reaction results in the production of labeled polyphosphate; (b) permitting the labeled polyphosphate to react with a phosphatase to produce a detectable species characteristic of the sample; (c) detecting the detectable species; and (d) characterizing the nucleic acid sample based on the detection.
摘要:
A landfill cover composition comprising a concentrate formulated to include a hardening agent, a thickener and emulsifier, and a super absorbent polymer, mixable with water and a filler material, such as cellulose or wood fiber mulch. A mixture of water, filler material and concentrate is sprayed on the surface of a landfill refuse layer and hardened to provide at least a temporary cover as an alternative to a significantly thicker or deeper layer of conventional soil or earth cover. The biodegradable composition preferably includes Plaster of Paris and guar gum compositions and cross-linked sodium acrylate polymer fines, mixed with the filler material and water at a landfill site for reducing transportation and handling costs.

A device and method of operation for filling medicine capsules, in which a fixed quantity of open capsules to be filled are supported in a circular array by a holder plate beneath the periphery of a rotatable distribution drum. In use, a measured supply of filling medication, in dry granular form, is dispensed into the center of the rotating drum where it is distributed evenly by centrifugal force along the periphery of the drum. As the drum stops rotating, the medication flows by gravity into the capsules, which are then inspected, closed and packaged. The distribution of filler material is more even than if the capsules were filled by hand, and the average quantity (both by volume and by weight) of the filling material per capsule in the batch is variable to suit an individual patient's needs, and very accurately known. In addition, two or more compatible filler medications may be mixed in the same capsules to suit the specialized needs of a particular user. Because the provided quantity of medication is completely distributed into each batch of capsules, inadvertent double-filling is prevented.
摘要:
Until recently, conducting polymers have been used as protective coatings.lthough these types of polymers appear to be effective in most cases, problems have resulted when attempting to bind these polymers to an aluminum surface. The polymers of this invention adhere extremely well to aluminum and aluminum alloys and thus, provide a very effective form of corrosion protection.
摘要:
A foldable handlebar for an exercise machine of the type that has a base frame, laterally spaced foot support members carried by the base frame, and a main strut attached to the base member and extending upwardly therefrom. The handlebar is rotatably attached atop the main strut so that each individual user can adjust the handlebar to accommodate his or her particular measurements.

A method for mounting lead sockets in the holes in an electrical interconnection board. The lead sockets are hollow cylindrical elements having a tapered opening at one end and a plurality of normally converging flexible fingers at the other end. The lead sockets are force fitted into the holes in the board with the receptacle end of the socket opening into the component side of the board. The lead sockets are vibrated into place while a vacuum is applied to temporarily seat the lead sockets in the holes in the board. The lead sockets are then finally force fitted into the holes in the board by several alternative means. The apparatus for accomplishing the method of this invention is also disclosed.
摘要:
A device and a method for creating and/or maintaining an obstruction free upper airway. The device is configured to fit under the chin of a subject adjacent to the subject's neck at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The device is capable of exerting negative pressure on the surface of a subject's neck, displacing the soft tissue forward and enlarging the airway.
摘要:
A wellhead housing has a telescoping casing hanger with an actuator mechanism to provide for direct transfer of casing and pressure loads to the housing. The transfer of casing and pressure loads occurs even in conditions where the telescoping casing hanger may be set in a high position in the wellhead housing on a load shoulder. The transfer of casing and pressure loads also occurs in conditions where the telescoping casing hanger may be set in an earlier installed casing hanger in the wellhead housing for a larger diameter casing string.
摘要:
Methods and systems are provided for improving fluid usage while addressing knock by adjusting the use of spark retard and direct injection of a fluid based on engine operating conditions and the composition of the injected fluid. One or more engine parameters, such as EGR, VCT, boost, throttle position, are coordinated with the direct injection to reduce torque and EGR transients.
