Abstract: A heat exchanger having a plurality of heat exchanger plate pairs. Each plate has a longitudinal central planar portion and a peripheral edge portion extending from it. The plate is provided with a first boss and a second boss having an inlet and outlet, respectively. A rib is also provided extending from the peripheral edge portion to the central planar portion, the rib having a mating surface, where the rib mating surface of a first plate in a first plate pair is in contact with a rib mating surface of a second plate in an adjacent plate pair.

Abstract: A method of electroplating an object includes providing a electroplating bath solution with one or more anodes therein, disposing an object to be electroplated in the bath, and passing a complex current waveform between the anode nodes and the object. The waveform is a cyclic alternating type having two portions, a positive triangular shaped portion including one or more spikes and a negative portion. The method further includes vibrating the object and/or agitating the bath solution.

Abstract: The present invention provides methods for preventing the generation of active thrombin on the surface of cells. The present methods are based upon the surprising discovery that expression or activation of an ER resident chaperone protein in a cell inhibits the generation of thrombin on the surface of the cell. Accordingly, expressing or activating an ER resident chaperone protein can be used to treat or prevent any of a number of thrombotic diseases.
