Server system then causes the media content item to be displayed on a display screen of at least one of a plurality of client computing devices. Other embodiments are described herein.

Abstract: Method of generating customized graphics based on location information includes processor receiving location information including location of first client device. Processor causes a status interface to be displayed on the first client device that includes locations that are within a predetermined distance from the first client device. Processor receives a selection from the first client device of the first location via the status interface and stores the first location in a location database associated with the first user. Location database includes: locations previously selected by the first client device via the status interface, locations associated with media content items received from the first client device, or locations associated with the location information received from the first client device.

Abstract: A method includes receiving an indication from a client computing device that a first user has selected one or more options from a composer interface to schedule a live video for broadcast by the first user at a future start time. The method also includes determining one or more second users who are connected to the first user in a social graph and sending a first notification to each of the second users. Each notification includes a first selectable option to receive a future notification about the live video. The method also includes sending a second notification to each of the second users who selected the first selectable option, the second notification including a second selectable option to view the live video. The method also includes providing the live video for display to the second users who select the second selectable option.

Abstract: Processes and systems for separating a mixture including at least one fluorocarboxylic acid and at least one carboxylic acid are provided herein. In some aspects, the present invention relates to processes and systems configured to provide a purified stream of fluorocarboxylic acid and a purified stream of carboxylic acid, even when the mixture includes an azeotrope, a pinch point, and/or a eutectic mixture of the fluorocarboxylic acid and carboxylic acid. Systems as described herein may include, for example, at least one distillation zone and at least one fractional crystallization zone arranged in series and configured to provide highly purified product streams having compositions heretofore unachievable by conventional means.

Abstract: Disclosed is a method for forming enals from corresponding alehydes in a single enclosed unit such as a divided wall reaction distillation unit. The method of the present invention includes (a) feeding an aldehyde feed stream comprising at least one aldehyde reactant into a reaction zone contained within said single enclosed unit; (b) reacting said at least one aldehyde reactant in said reaction zone in the presence of a catalyst to form an enal-containing reaction zone effluent comprising an enal; (c) purifying said enal-containing reaction zone effluent in a first separation zone within said single enclosed unit to form an enal-rich product mixture and a residual unreacted aldehyde mixture; and (d) collecting from said single enclosed unit at least a portion of said enal-rich product mixture. The method of the present invention results in high enal yields at a markedly reduced capital cost and energy consumption as compared to prior art processes.

Abstract: Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.

Abstract: The present invention pertains to methods and systems for on demand droplet generation and impedance based detection. The microfluidic system can utilize an electrical sensor for detecting an electrical property of a fluid and for generating an electrical signal indicating a change in the electrical property of the fluid; a droplet generator coupled to the electrical sensor configured to generate the droplet from the fluid in response to the electrical signal from the electrical sensor; and a microfluidic channel coupled to the droplet generator for receiving the droplet. The method for generating droplets involves measuring an electrical property of the fluid, transmitting an electrical signal indicative of the electrical property, and forming the droplets from the fluid based on the electrical signal.
