  • Patent number: 7547526
    Abstract: Methods and kits for the isolation of organisms. Such methods and kits are particularly useful for concentrating and recovering viable organisms from food material. The recovered organisms are of sufficient number and purity to allow detection using a biochip device.
    Type: Grant
    Filed: March 15, 2005
    Date of Patent: June 16, 2009
    Assignee: Purdue Research Foundation
    Inventors: Michael R. Ladisch, Xingya Liu, Amanda C. Stewart, Wan-Tzu Chen, Nathan S. Mosier, Thomas Huang, Jeremiah Bwatwa, Richard Hendrickson
  • Publication number: 20070168053
    Abstract: A computer implemented method, data processing system, and computer usable code are provided for analyzing input/output problems. A monitoring agent collects input/output data from a plurality of levels in a multi-level input/output stack. The monitoring agent analyzes the input/output data from the plurality of levels to form an analysis. A determination is then made as to whether the analysis requires an action and an action is initiated in response to a determination that the analysis requires an action.

  • Patent number: 6347599
    Abstract: This invention relates to stabilization and propulsion of windsurfing and other floating boards such as surf boards. The invention consists of a modular device consisting of a seat and pontoon float unit fitted with remote controls by which a modified trolling motor can be used to steer and propel the board through the water.

  • Patent number: 5808010
    Abstract: A solid sorbent material comprising cellulose which has been modified by hydrolysis with a cellulase enzyme for a duration sufficient to increase the protein adsorption capacity of the solid sorbent material and methods for preparing the sorbent material. Methods for purifying a protein include passing a liquid medium containing the protein over the solid sorbent material are also included.
    Type: Grant

  • Patent number: 5770060
    Abstract: Devices and methods for packing a chromatography column with a continuous stationary phase. The preferred device includes a brace member with an engagement surface. The brace member defines a thru-hole at a location so that a passageway defined through the column is aligned with the thru-hole of the brace member when a first end of the column is engaged with the engagement surface of the brace member. A funnel member engageable with an end of the column opposite the first end. The funnel member has converging walls configured to radially compress the continuous stationary phase for entry into the passageway of the column when the continuous stationary phase is pulled through the funnel member. The device includes a mechanism for applying mechanical force to pull the rolled continuous stationary phase through the funnel member wherein the stationary phase is radially compressed and enters the passageway of the column.
