| 20090176255 | IMMUNOMAGNETIC CAPTURE AND IMAGING OF BIOLOGICAL TARGETS - The present invention relates to methods and systems for labeling, isolating, detecting, and/or enumerating a statistically significant number of biological cells, or other biological analytes of interest, present in a complex matrix sample. The isolation of a biological target of interest from a sample mixture is done by immunomagnetic separation. Upon introduction of the sample within an imaging chamber, the capture complex (biological target-magnetic capture agent) will be attracted by the magnetic field and will lay on the surface of the chamber in the focal plane of the imaging system. | 07-09-2009 |
| 20110086431 | Methods for Altering Surface Characteristics of Microspheres - Various methods for altering surface characteristics of a microsphere are provided. One method includes coupling an enolic acid to the microsphere to modify the surface characteristics of the microsphere. The surface characteristics may include charge density and/or pKa. A reagent can be coupled to the microsphere via the enolic acid. The reagent may include a biomolecule. The modified surface characteristics may increase a stability of the reagent when the reagent is coupled to the microsphere. The modified surface characteristics may also improve performance of an assay carried out with the microsphere. Another embodiment relates to a microsphere that includes an enolic acid coupled to a polymer core of the microsphere such that the enolic acid modifies surface characteristics of the microsphere. A reagent can be coupled to the microsphere via the enolic acid. | 04-14-2011 |

| 20100226767 | DIFFUSER ARRANGEMENT - A diffuser arrangement through which a fluid may flow is provided. The diffuser includes an outer diffuser comprising an inner surface, and a flow-guiding device, which is configured such that at least part of the boundary layer flow forming on the inner surface of the outer diffuser can be accelerated in the main flow direction, so that a flow separation is prevented on the inner surface of the outer diffuser. Also provided are an exhaust steam plenum of a steam turbine and an exhaust gas plenum of a gas turbine, both including a diffuser arrangement. | 09-09-2010 |
| 20110100008 | Method and Device for Operating a Steam Power Station Comprising a Steam Turbine and a Process Steam Consumer - A method for operating a steam power station is provided. The steam turbine power station includes at least one steam turbine and a process steam consumer, wherein a steam mass flow is subdivided into a first partial mass flow and a second partial mass. In a first operating state, the first partial mass flow is supplied to the steam turbine and the second partial mass flow is supplied to the process steam consumer. In a second operating state, at least part of the second partial mass flow is supplied to the steam turbine at least after the first turbine stages. A steam power station is also provided. | 05-05-2011 |
