Abstract: User interfaces facilitate user interaction with virtual representations of anatomical structures that are displayed on computing systems. The user interfaces demonstrably reflect the relative impact of different medical conditions on the anatomical structures. The impact of the medical conditions can be reflected in real-time, as a slider object is manipulated to pull a slide transition screen over the anatomical object. Portions of the anatomical object that become overlapped by the slide transition screens are displayed with dynamic modifications that reflect the impact of the medical conditions associated with the slide transition screens.

Abstract: A three-part bleach-fix regeneration kit is utilized to restore the capability of a spent bleach-fix solution to function as a working solution in photographic processing. The first part, which is an aqueous alkaline solution containing a buffering agent and an aminopolycarboxylic acid, is added to the spent bleach-fix solution prior to electrolytic recovery of silver therefrom. The second and third parts, which are aqueous acidic solutions containing, respectively, an iron salt and a thiosulfate fixing agent, are added after electrolytic recovery of silver. The first part functions to increase the pH of the spent bleach-fix solution to a level at which electrolytic silver recovery is optimized, while the second and third parts function to lower the pH to an optimum level for use in photographic processing. In addition to providing the necessary pH changes, addition of the three parts in this manner restores all necessary components to their proper concentration.

Abstract: A highly selective zeolitic reforming catalyst is disclosed that contains a promoter selected from the group consisting of iron, cobalt, and titanium; and that has a platinum to promoter weight ratio of less than 10:1. In one embodiment a type L zeolite is formed by combining an aqueous solution of potassium hydroxide, aluminum hydroxide, and ferric nitrate with an aqueous solution of silica to form a thickening gel in a mother liquor; heating the thickening gel to form a type L zeolite; cooling the solution containing the type L zeolite; decanting the mother liquor from the solution; filtering the type L zeolite from the solution; washing the filtered type L zeolite so that the pH of the wash is about 101/2; and drying the washed type L zeolite. The catalyst is formed by adding platinum to the dried type L zeolite by pore fill impregnation with an aqueous solution of Pt(NH.sub.3).sub.4 (NO.sub.3).sub.2 to form a catalyst; drying the catalyst and calcining the catalyst.
