  • Publication number: 20120231072
    Abstract: A thermo-responsive hydrogel, including a biocompatible monomer and/or polymer having an amino acid side chain. The hydrogel is thermo-responsive at a physiological temperature, and can include, incorporate, or encapsulate a treatment agent, such as a drug composition, a biomolecule, and/or a nanoparticle. The hydrogel is useful in delivering the treatment agent. The hydrogel is in a first physicochemical state for administration to a mammal. The hydrogel is thermo-responsive at a physiological temperature of the mammal, and changes to a second physicochemical state that is more solid than the first physicochemical state. In the second physicochemical state the thermo-responsive hydrogel releases the treatment agent.

  • Patent number: 8216363
    Abstract: A process and system for continuous crystallization of a compound using antisolvent addition in which a solution is prepared with an organic compound and a solvent. An antisolvent is added to the solution in a continuous plug flow system comprising at least one process module. The antisolvent can be added in multiple addition points such that the overall amount of antisolvent added to the continuous plug flow reactor remains fixed. The multiple addition point technique provides every process module with an equal volume of antisolvent. Finally, crystals are recovered from the slurry upon exiting the system. Preferably, the mean crystal size is less than 100 ?m.

  • Patent number: 8195172
    Abstract: The invention disclosed is a process to allocate channels in a sectorized and tiered cellular network. A system of allocating cellular frequencies (channels) to the sectors among the outer tier of cells within a tile is disclosed which maximizes channel set usage within the tile while minimizing co-channel interference between cells. Any unused, or remaining, frequencies for the outer tier of that cell may then be allocated to an inner tier of the cell that has not had a channel allocated thereto. No additional infrastructure or maintenance set-up is required under this technique for allocating the channel to the additional transceiver and a very high degree of channel utilization is achieved.

  • Patent number: 8166911
    Abstract: A method and apparatus for electrostatic spray deposition (ESD) for fabricating a thin-layer yttria-stabilized zirconia (YSZ) electrolyte on a solid oxide fuel cell (SOFC) anode substrate constructed of nickel-YSZ cermet. By reducing the thickness of the electrolyte, and thereby reducing the cell internal IR drop, an intermediate temperature SOFC (ITSOFC) can operate at 600-800° C. A collar positioned at a distance from a discharge end of a spray nozzle enhances a spray pattern of a precursor including the electrolyte material and thus provides a very thin electrolyte layer.

  • Patent number: 8165591
    Abstract: The invention disclosed is a process to allocate channels in a sectorized cellular network. A system of allocating cellular frequencies (channels) to the sectors among the cells within a tile is disclosed which maximizes channel set usage within the tile while avoiding co-channel interference between cells. According to the present system, no infrastructure rebuild is required. The disclosed approach further supports all currently used cellular technology. By alternating and rotating the channel assignments across sectors, what is a seemingly locally poor algorithm utilizing additional local channels is actually a globally good algorithm which is efficient in terms of the total number of channels used owing to short reuse distance and low number of cell types.

  • Patent number: 8093038
    Abstract: An apparatus and method for coating micron-sized or sub-micron-sized particles such as living cells. The coating apparatus includes an encapsulation chamber enclosing a two-layer water-oil system for coating each islet cell with an aqueous polymeric coat. Islets together with an aqueous polymer solution are fed by a feed device that utilizes the principle of hydrodynamic focusing in order to ensure encapsulation of individual islets. The polymer in the aqueous coat is subsequently crosslinked by being exposed to laser light to produce structurally stable microcapsules of controllable thickness of the order of tens of microns. Encapsulated islets are removed from the encapsulation chamber by a valveless pump and recovered by filtration or centrifugation.

  • Patent number: 8066828
    Abstract: A method for heat treatment of steel and a system thereof is provided. First the steel is austenitized at a suitable temperature and then the temperature is rapidly brought down to the austempering temperature. Here the cyclic austempering is carried out between two austempering temperatures by modulating the temperature with controlled heating and cooling and the controlled temperature modulation is obtained by controlling the temperature-time profile in a batch furnace or by controlling the zone temperatures in a continuous furnace. This method of cyclic austempering reduces the austempering time, reduces the energy consumption and emissions, enhances the productivity and reduces the process cost.
