| 20090014313 | Low-energy extractive distillation process for dehydration of aqueous ethanol - An energy-efficient extractive distillation process for producing anhydrous ethanol from aqueous/ethanol feeds containing any range of ethanol employs an extractive distillation column (EDC) that operates under no or greatly reduced liquid reflux conditions. The EDC can be incorporated into an integrated process for producing anhydrous ethanol used for gasoline blending from fermentation broth. By using a high-boiling extractive distillation solvent, no solvent is entrained by the vapor phase to the EDC overhead stream, even under no liquid reflux conditions. The energy requirement and severity of the EDC can be further improved by limiting ethanol recovery in the EDC. In this partial ethanol recovery design, ethanol which remains in the aqueous stream from the EDC is recovered in a post-distillation column or the aqueous stream is recycled to a front-end pre-distillation column where the ethanol is readily recovered since the VLE curve for ethanol/water is extremely favorable for distillation. | 01-15-2009 |

| 20100041041 | NUCLEOTIDES AND NUCLEOSIDES AND METHODS FOR THEIR USE IN DNA SEQUENCING - The present invention relates generally to labeled and unlabled cleavable terminating groups and methods for DNA sequencing and other types of DNA analysis. More particularly, the invention relates in part to nucleotides and nucleosides with chemically cleavable, photocleavable, enzymatically cleavable, or non-photocleavable groups and methods for their use in DNA sequencing and its application in biomedical research. | 02-18-2010 |
| 20110200988 | 3'-OH unblocked uncleotides and nucleosides base modified with non-cleavable, terminating groups and methods for their use in DNA squencing - Provided are novel nucleotides, nucleoside, and their derivatives described herein, that can be used in DNA sequencing technology and other types of DNA analysis. In one embodiment, the nucleotide or nucleoside with an unprotected 3′-OH group is derivatized at the nucleobase to include a fluorescent dye attached via a linker to a non-cleavable terminating group. The non-cleavable-fluorescent group is designed to terminate DNA synthesis so that DNA oligomers can be sequenced efficiently in a parallel format. These reagents and methods will lead to more accurate identification of polymorphisms and other valuable genetic information. | 08-18-2011 |

| 20090306945 | Upscaling Reservoir Models By Reusing Flow Solutions From Geologic Models - Method is provided for simulating a physical process such as fluid flow in porous media by performing a fine-grid calculation of the process in a medium and re-using the fine grid solution in subsequent coarse-grid calculations. For fluid flow in subsurface formations, the method may be applied to optimize upscaled calculation grids formed from geologic models. The method decreases the cost of optimizing a grid to simulate a physical process that is mathematically described by the diffusion equation. | 12-10-2009 |
| 20100057418 | Method for Quantifying Reservoir Connectivity Using Fluid Travel Times - The present application describes a method and system associated with the production of hydrocarbons. In the method, fluid travel time models are constructed from a reservoir model. Then, reservoir connectivity measures are calculated from the fluid travel time models and analyzed to determine a location for at least one well. Based on the analysis, one or more wells may be drilled and hydrocarbons produced. | 03-04-2010 |
| 20100128041 | Generation of Constrained Voronoi Grid In A Plane - A method for generating constrained Voronoi grids in a plane with internal features and boundaries is disclosed. The disclosed method generally includes approximation of internal features and boundaries with polylines based on plane geometry. Protected polygons or points are generated around the polylines, and Delaunay triangulation of protected points or protected polygon vertices is constructed. Delaunay triangulation that honors protected polygons or points is generated in the rest of the gridding domain. The constrained Voronoi grid is then generated from the Delaunay triangulation, which resolves all of the approximated features and boundaries with the edges of Voronoi cells. Constrained Voronoi grids may be generated with adaptive cell sizes based on specified density criterion. | 05-27-2010 |
| 20110169838 | Generation of Constrained Voronoi Grid In A Plane - A computer-implemented method for generating a constrained Delaunay triangulation for a planar domain with boundaries and internal features. The boundaries and internal features of the domain are approximated with polylines. Unconstrained Delaunay triangulation is constructed for the domain. The unconstrained Delaunay triangulation is modified to conform triangle sides to the polylines. The modified triangulation is corrected to make it a constrained Delaunay triangulation. At least one of the steps of the method is implemented using a computer. | 07-14-2011 |
