Abstract: Fabrication of a microfluidic multi-temperature reaction device (MMR) and the design and fabrication of the equipment to drive various molecular biological methods on the device are provided. The device can be applicable, for example, to nucleic acid (DNA, RNA, cDNA, etc) amplification, cell lysis, reverse transcription and other enzymatic temperature sensitive and also temperature cycling reactions.

Abstract: Various embodiments of the present disclosure generally relate to molecular biological protocols, equipment and reagents for the extraction and fractionation of DNA molecules, from whole or lysed samples, in a single flow-through device.

Abstract: An isometric strength testing device includes a base for selectively supporting either a chair or a wheelchair for the subject to be tested. A pair of limb supports are positioned on the base, one to immobilize an arm and the other a leg of the subject. Each support includes a band carrying a load cell for generating a signal measurement of the force applied to the cell. Goniometers are associated with the supports for establishing appropriate angles of the subject's limbs at the knee and elbow. A computer connected to the force plates processes and displays data generated by the load cells.

Abstract: A dredge supporting a pivotal ladder with a suction auger on its free end. A shroud assembly including front, center and rear sections surrounds a large portion of the periphery of the auger. The shroud assembly is pivotal about the axis of the auger and the front and rear sections are each independently pivotal relative to the center section so that the center section can be maintained at a relatively constant attitude independent of the inclination of the ladder and only a leading one of the front and rear sections, depending on the direction of movement of the dredge, is necessarily opened while the trailing section can remain closed adjacent to the auger. The articulation of the several shroud sections enables the suction auger head to operate in both directions with reduced turbidity and, therefore, increased efficiency.
