Abstract: A computer-implemented method that includes displaying a graphical user interface (“GUI”) and receiving personalized information from at least one server computing device. The GUI includes a page. The personalized information identifies a theatre location, movies playing at the theatre location, dates, and showtimes associated with the movies and dates. The method includes displaying on the page, the movies, dates on which a particular movie is showing, and a particular showtime on a particular date. A selection is entered by the user into a user input displayed on the page. The selection changes the theatre location, the particular movie, the particular date, and/or the particular showtime without the user exiting the page. The page updates automatically to display the user selection. An indication is received that the user has selected a purchase input display on the page, and a purchase of at least one movie ticket is completed.

Abstract: A system, apparatus, and method include a pump to deliver vapor including airborne contaminants including organic compounds including a target analyte; a collector to transfer the airborne contaminants by autonomous liquid extraction into a mobile organic liquid phase; a micro-fluidic chamber including immobilized biorecognition elements that bind to analytes delivered from the mobile organic liquid phase; a mechanism to introduce the mobile organic liquid phase to a buffer containing a plurality of substrates causing a series of biochemical reactions that create a change corresponding to a concentration of the target analyte; and a detector to perform real-time analysis that correlates to a concentration of the organic compounds to determine a presence of the target analyte.

Abstract: A non-destructive process for removing chromium from polyvinyl chloride filters is disclosed. The process involves immersing the polyvinyl chloride filters in a concentrated hydrogen peroxide solution at elevated temperatures, followed by rinsing with deionized water. Removing the background concentration of chromium from the filters allows for more accurate measurements of the amount of hexavalent and total chromium present in workplace environments.
