Abstract: Sensor systems can be used to measure an analyte concentration. Sensor systems can include a base having a distal side configured to face towards a person's skin. An adhesive can couple the base to the skin. A transcutaneous analyte measurement sensor can be coupled to the base and can be located at least partially in the host. A transmitter can be coupled to the base and can transmit analyte measurement data to a remote device.

Abstract: A boiling water reactor core according to an example embodiment may include a core shroud and a plurality of fuel bundles within the core shroud. A plurality of shielding bundles are arranged as a fast flux shield between the plurality of fuel bundles and the core shroud. The plurality of shielding bundles include a metal hydride as a neutron moderator.

Abstract: There is provided an oven having an oven door assembly connected to a housing. The housing surrounds an oven interior and has an opening into the oven interior. The door assembly has an oven access door that covers the opening in the housing in a closed position. The oven access door moves in a first direction from a closed position to an open position uncovering the opening into the oven interior. The oven has a depth in the closed position. The oven access door moves in the first direction from the closed position to the open position within substantially the same depth of the oven in the closed position.

Abstract: A method to confine a nuclear reactor fuel bundle assembly including: inserting a lower portion of the fuel bundle assembly into an open end of a lower fuel particle barrier; supporting the lower portion of the fuel bundle with the lower fuel particle barrier; grasping the lower portion of the fuel bundle assembly with the lower fuel particle barrier; lowering an upper fuel particle barrier over an upper tie plate of the fuel bundle assembly; moving at least a portion of a handle fixed to the upper tie plate through an open slot in the upper fuel particle barrier; closing the open slot with a closure device after the handle passes through the slot, and preventing fuel particles being released from the nuclear reactor fuel bundle assembly by the upper and lower fuel particle barriers.

Abstract: A fuel channel according to example embodiments for a nuclear reactor may have an elongated and hollow body with a multi-layer structure. The multi-layer structure may include a core layer and at least one cladding layer metallurgically-bonded to the core layer. The core layer and the at least one cladding layer may be alloys having different compositions. For instance, the core layer may be significantly more resistant to irradiation growth and/or irradiation creep than the at least one cladding layer, and the at least one cladding layer may have an increased resistance to hydrogen absorption and/or corrosion relative to the core layer. Accordingly, the distortion of the fuel channel may be reduced or prevented, thus reducing or preventing the interference with the movement of the control blade.

Abstract: A method of using one or more electric locomotive and energy storage car combinations to assist a train consist up an uphill climb, the one or more electric locomotive and energy storage car combinations each having one or more diesel electric locomotives and one or more separate energy storage cars, including adding the one or more electric locomotive and energy storage car combinations to the train consist prior to an uphill climb; using the one or more electric locomotive and energy storage car combinations to assist the train consist up the uphill climb; and removing the one or more electric locomotive and energy storage car combinations from the train consist after the uphill climb. The one or more electric locomotive and energy storage car combinations are added to a train consist traveling downhill to assist with the downhill slowing through dynamic braking regeneration that is used to recharge the energy storage of the one or more separate energy storage cars.

Abstract: An improved process for sulphonation of organic compounds, notably hydroxybenzene and alkylbenzene compounds, comprises reacting them with sulphuric acid or oleum in the presence of an organic solvent, notably an n-alkane or a cycloalkane. Also described is a method of extracting an alkylbenzene sulphonic compound from a sulphonation reaction mixture, using an alkylbenzene extractant of lower molecular weight, for example cumene. Some of the alkylbenzene sulphonic compounds are novel.
