  • Publication number: 20250163315
    Abstract: A composition for stimulating a wellbore, subterranean formation or reservoir, comprises a stimulating fluid such as an acid; a rate modulator configured to reduce or decrease the rate of reaction between the stimulating fluid and the wellbore, subterranean formation or reservoir; and a dispersant. The composition may be suitable for use in acid treatment, e.g. acid stimulation, of a wellbore, subterranean formation or reservoir.

  • Patent number: 10500317
    Abstract: Orthopedic and dental implants coated with an antibacterial coating and methods of making and using, are described herein. The implant can be coated with a hydrophobic, polycationic antibacterial polymer. The polymer can be covalently or non-covalently associated with the surface; however, in particular embodiments, the polymer is non-covalently associated with the surface. As shown in the examples below, clinical observations, digital radiography, and a battery of well-accepted ex vivo analytical methods show that the presence of a hydrophobic polycationic polymer coating, such as N,N-dodecyl,methyl-PEI coating on the surface of a metal implant, was effective in eliminating the clinical signs of infection in vivo in a large animal infection model. Moreover, the coated plates supported bone healing, and in fact decreased healing times, even in the presence of significant bacterial contamination compared to a control.

  • Patent number: 7966350
    Abstract: An evidence repository application system provides a centralized repository of implementation evidence data for a project and to provide a method for collecting, storing and tracking the implementation evidence data for the project. The evidence repository application system receives and stores evaluation data regarding the implementation evidence data. The evidence repository application system generates interactive reports summarizing the evaluation data for a project. The evidence repository application system implements a consistent approval process for a project with identified accountable managers and evidence providers. The evidence repository application system also implements an accountability process that notifies accountable managers and evidence providers of their roles and responsibilities for a project.
