Abstract: A nuclear reactor includes a heat exchanger that transfers thermal energy from a primary reactor coolant to a secondary coolant. The heat exchanger is formed with a hot flow channel, a cold flow channel, and a porous layer between the hot flow channel and the cold flow channel. The porous layer may be thermally insulative to reduce the efficiency of thermal energy transfer from the hot flow channel to the cold flow channel. The porous layer may have a control gas passed therethrough that can be tailored to control the thermal energy transfer through the porous layer. The control gas can be tested for leakage within the heat exchanger. The control gas may also be used to sequester fission or activation products.

Abstract: In some implementations, an apparatus includes a curved portion of a storage tank having an exterior surface, having an interior surface and having a defect, the apparatus also includes a steel patch positioned over the curved portion of a storage tank, a plurality of studs and nuts positioned near an outer perimeter of the steel patch, in which the plurality of studs being friction welded to the exterior surface of the curved portion of a storage tank.

Abstract: A fabric care composition is provided, comprising: water; fragrance; and deposition aid polymer, comprising dextran base polymer functionalized with quaternary ammonium groups; wherein quaternary ammonium groups include a quaternary ammonium group of formula (II) bound to a pendent oxygen on the dextran base polymer and a quaternary ammonium group of formula (III) (II) (III); wherein is pendent oxygen on dextran base polymer; wherein X is a divalent linking group; wherein R2 is selected from C1-4 alkyl group; wherein R3 is selected from C1-4 alkyl group; and wherein R4 is selected from linear or branched C8-20 alkyl group; wherein degree of substitution, DS(II), of formula (II) on deposition aid polymer is 0.01 to 0.245; wherein degree of substitution, DS(III), of formula (III) on deposition aid polymer is >0 to 0.05; and wherein deposition aid polymer enhances deposition of fragrance onto fabric relative to otherwise identical formulation without deposition aid polymer.

Abstract: A system comprises a robotic manipulator for control of motion of a medical tool. The robotic manipulator including a joint and a link connected to the joint. The link is configured to connect to the medical tool. A processing unit of the system is configured to receive first data from an encoder of the joint. A first tool tip estimate of a first parameter of a tool tip coupled at a distal end of the medical tool is generated using the first data. The first parameter of the tool tip is a position or a velocity of the tool tip. Second data is received from a sensor system located at a sensor portion of the link or the medical tool. The joint is controlled based on a first difference between the first tool tip estimate and a second tool tip estimate generated using the first and second data.

Abstract: Freight forwarders and carriers post published rate and discount information for land, sea and air bearing cargo vessels to allow customers the opportunity to evaluate competitive prices, preferably in one consolidated location (e.g., a web site). A customer navigates to the site to obtain published or discounted rate information offered by a freight forwarder or carrier. The customer may accept a posted rate, in which case the site operator notifies the freight forwarder or carrier. Alternatively, customers, freight forwarders and carriers may negotiate rates for particular lanes of interest using an online interactive auction block.
