Abstract: Genetically modified microorganisms that have the ability to convert carbon substrates into chemical products such as 2,3-BDO are disclosed. For example, genetically modified methanotrophs that are capable of generating 2,3-BDO at high titers from a methane source are disclosed. Methods of making these genetically modified microorganisms and methods of using them are also disclosed.

Abstract: A process for the epoxidation of propene involves reacting propene with hydrogen peroxide, in the presence of a methanol solvent and a shaped titanium zeolite epoxidation catalyst in a fixed bed reactor. The process then involves recovering methanol from the reaction mixture, treatment of the recovered methanol by passing it through a bed of an acidic ion exchange resin, and recycling the treated methanol to the epoxidation reaction; as well as regeneration of the acidic ion exchange resin. Catalyst breakage can be reduced or avoided by washing the regenerated bed of an acidic ion exchange resin with methanol until the methanol exiting the resin bed has an apparent pH higher than 1.8, before methanol treated with the acidic ion exchange resin is recycled to the epoxidation reaction.

Abstract: An element, particularly a transparent element, including at least one glass element, configured as a protective glass against ionizing radiation and/or UV radiation, wherein at least a portion of the surface of the glass element is covered by a film that includes a substance that can be switched into at least two states.

Abstract: A large-area display device, in particular multimedia façade, comprises at least one transparent element, in which the transparent element comprises at least one transparent substrate on which one or more lighting elements is/are arranged.

Abstract: An Alert/Warning Interface resides in a set top box, which is coupled to a user's television, and an Information Server located in the cable plant origination center or head-end. The end user of the set top box is able to configure a profile that includes weather areas to be monitored, roads traveled, and schools their children attend. This profile is stored on the Information Server, along with the profiles of all other users. The Information Server monitors for alert conditions, such as bad weather, traffic jams, and school closings. If any of these events occurs, a message is sent to the set top box associated with a profile indicating the current error condition. Upon receipt of an Alert message, the set top box places an icon (or other graphic) in a predetermined portion of the screen (e.g., a top/bottom corner) indicating an alert has occurred. The user can then switch to the Alert screen view, at which time the Alert icon turns off.
