Abstract: A computer-implemented method of object enhancement in endoscopy images includes capturing an image of an object within a surgical operative site via an imaging device, determining a size of the object based on the captured image of the object, displaying the captured image of the object, and displaying on the displayed captured image of the object a representation of the determined size of the object.

Abstract: A method of performing robotic surgery includes determining a distance between a first surgical instrument and a second surgical instrument in a surgical operative site, comparing the determined distance between the first and second surgical instruments with a threshold distance, generating an alert based on the comparison between the determined distance and the threshold distance, displaying a visual representation of the surgical operative site on a display, and displaying the alert overlaid on the displayed visual representation of the surgical operative site and in proximity to a visual representation of the first and/or second surgical instruments on the display.

Abstract: Described is a selective catalytic reduction catalyst comprising a zeolitic framework material of silicon and aluminum atoms, wherein a fraction of the silicon atoms are isomorphously substituted with a tetravalent metal. The catalyst can include a promoter metal such that the catalyst effectively promotes the reaction of ammonia with nitrogen oxides to form nitrogen and H2O selectively over a temperature range of 150 to 650° C. In another aspect, described is a selective catalytic reduction composite comprising an SCR catalyst material and an ammonia storage material comprising a transition metal having an oxidation state of IV. The SCR catalyst material promotes the reaction of ammonia with nitrogen oxides to form nitrogen and H2O selectively over a temperature range of 150° C. to 600° C., and the SCR catalyst material is effective to store ammonia at temperatures of 400° C. and above.

Abstract: A well fluid additive having a heavier first bead and a lighter second bead, with the first bead having a specific gravity that exceeds the specific gravity of the second bead by at least 1 percent.

Abstract: A well fluid additive system prepackaged to the specifications of each particular well. The system comprises a supporting member, and a plurality of additives which additive is each individually segregated from the other additives. This system reduces waste as the exact proportions are delivered to the well as needed.

Abstract: The present invention is directed to a diesel oxidation catalyst for the treatment of exhaust gas emissions, such as the oxidation of unburned hydrocarbons (HC), and carbon monoxide (CO) and the reduction of nitrogen oxides (NOx). More particularly, the present invention is directed to a novel washcoat composition comprising two distinct washcoat layers containing two distinctly different ratios of Pt:Pd.
