  • Publication number: 20070124265
    Abstract: In accordance with one aspect of the present invention, a method for implementing a diagnostic system pertaining to a complex system includes receiving, by a computer implemented system, an observed symptom that characterizes a discrepancy report of a complex system, associating the observed symptom with contents of at least one electronic manual to capture relevant information therefrom, and evaluating the relevant information by the computer implemented system to recommend at least one desired action for mitigation of the discrepancy report without assuming knowledge about a historical discrepancy report similar to the reported discrepancy.

  • Publication number: 20050265928
    Abstract: Particulate compositions for delivery, preferably pulmonary, which provide sustained release of antigens, preferably DNA and/or peptide and/or protein antigens, have been developed. In the preferred embodiment, aggregate nanoparticles are in the aerodynamic range of 1-5 microns diameter and fly deep into the lungs. As the aggregate particles degrade in the body, MSP-1 and AMA-1 proteins are released into the blood stimulating a humoural immune response. The individual particles in the range of 0.1 micron are preferentially phagocytosed by APCs which express the proteins encoded by AMA-1 and MSP-1 plasmid DNA thereby initiating the cellular immune response that is necessary for a complete immunity.

  • Publication number: 20040156957
    Abstract: A oil and moisture absorbent material suitable for use in food packages and a food package made of such material. The material comprises an oil and moisture absorbent layer covered by an oil and moisture repellent substance that has a multiplicity of perforations or which is applied in a pattern so that oil and moisture can pass through. Alternatively, the oil and moisture absorbent layer may be covered by an oil and moisture permeable substance. The oil and moisture absorbent layer may have indentations and additives that improve its oil and moisture absorbency. The oil and moisture absorbent layer may be made of a paperboard that is manufactured using a reduced level of calendering and having a reduced amount of sizing applied.

  • Publication number: 20040084163
    Abstract: A method for increasing the long term storageability of a cellulosic paper or paperboard product. The method includes providing a paper or paperboard product made from cellulosic fibers having a basis weight ranging from about 80 to about 300 pounds per 3000 square feet. A holdout material is applied to at least one surface of the paper or paperboard product. The web is then coated with an ink receptive material selected from the group consisting of an aqueous acrylic polymer coating material, an aqueous biocidal agent and a combination of aqueous acrylic polymer coating material and aqueous biocidal agent and dried to provide a paper or paperboard product having enhanced long term storageability. Webs made according to the invention are suitable for making file folders which exhibit improve long term storageability by resisting damage from moisture and/or biological activity.
