Abstract: A biodegradable plastic formulation comprises about 75 wt % to about 85 wt % of a biodegradable polymer, and about 15 wt % to about 25 wt % of poultry waste biochar comprising a particle size of 50 ?m or less. A process for producing a biodegradable plastic product comprises forming biochar from poultry waste; formulating about 75 wt % to about 85 wt % of a biodegradable polymer with about 15 wt % to about 25 wt % of the biochar and extruding the formulation to produce pellets; and using the pellets in a production process to produce the biodegradable plastic product.

Abstract: An apparatus for an aircraft having one or more aircraft wheel brakes, and a brake wear sensor configured to measure a wear state of a brake of the one or more aircraft wheel brakes, is disclosed. The apparatus includes a processor configured to determine a wear relationship between a wear state of the brake and a number of use cycles of the brake, determine a predicted wear state of the brake based on the wear relationship; determine a number of future use cycles of the brake based on a predicted condition of the brake, the predicted condition comprising the predicted wear state of the brake; and provide an indication of the determined number of the future use cycles to ground crew and/or a pilot of the aircraft, wherein the number of future use cycles is the number of use cycles for which the brake is allowed to be used, and a use cycle comprises all uses of the brake relating to a flight undertaken by the aircraft.

Abstract: An apparatus and method is disclosed for determining a temperature characteristic at a first location on a wheel or a brake assembly of an aircraft landing gear. The temperature characteristic at the first location is determined using relationship information based on a first temperature at a second location of the wheel or the brake assembly of the landing gear, the relationship information representing a relationship between the temperature characteristic at the first location and the first temperature. Also disclosed is a method to determine the relationship information.

Abstract: An apparatus and a method for determining a thermal oxidation state of a brake of an aircraft landing gear is disclosed. Determination of the thermal oxidation state of the brake involves determining a thermal oxidation state of the brake after a braking event, using a thermal oxidation model based on an initial thermal oxidation state before the braking event and a temperature profile of the brake with respect to time.

Abstract: An anaerobic electrochemical membrane bioreactor (AnEMBR) can include a vessel into which wastewater can be introduced, an anode electrode in the vessel suitable for supporting electrochemically active microorganisms (EAB, also can be referred to as anode reducing bacteria, exoelectrogens, or electricigens) that oxidize organic compounds in the wastewater, and a cathode membrane electrode in the vessel, which is configured to pass a treated liquid through the membrane while retaining the electrochemically active microorganisms and the hydrogenotrophic methanogens (for example, the key functional microbial communities, including EAB, methanogens and possible synergistic fermenters) in the vessel. The cathode membrane electrode can be suitable for catalyzing the hydrogen evolution reaction to generate hydrogen.
