摘要:
A method and system of evaluating a turbine component comprises obtaining data relating to respective surface conditions at a plurality of different surface locations of the turbine component and calculating the total profile efficiency loss for the turbine component based on the data. Calculating the total profile efficiency of the turbine component may include calculating the local profile efficiency loss percentage for each of the surface conditions at the different surface locations (and/or sub-areas of the different surface locations) and calculating an average of the local profile efficiency loss percentages, each of the local efficiency loss percentages being weighted by respective predetermined weight factors. The turbine component may be a nozzle or a bucket and each of the turbine component's surface locations may be an admission suction surface, an admission pressure surface, a discharge suction surface or a discharge pressure surface.

The present invention provides a method of diagnosing bipolar affective disorder (BAD) and for determining a predisposition of a subject to bipolar affective disorder. In particular, the methods of the present invention comprise detecting a marker that comprises one or more polymorphisms at position 4q35.2 of the human genome and/or one or more allelic variants of the FAT gene associated with BAD or linked thereto. The present invention also relates to identifying new markers that are diagnostic of bipolar affective disorder. Furthermore, the present invention relates to methods of identifying and producing candidate compounds for the treatment of bipolar affective disorder.
摘要:
In a reverse design for partitions of a steam turbine having decreased throat dimension therebetween with increased radial height, the trailing edges are set back from approximately mid-span to a tip of the partition to increase the throat dimension with radial height relative to the prior reverse design configuration. Secondary vortices adjacent the radial inner and outer end walls are maintained separated from on another by the design, thereby minimizing or eliminating aerodynamic losses from interactive secondary flow effects while improving flow distribution at the bucket entrance and stage exit. In a further embodiment, a free vortex design having increasing throat dimension from the hub to the tip may be modified to further increase the throat dimension from the hub to approximately the mid-span by providing setbacks along the trailing edge of the partition between the hub and mid-span. The setbacks can be provided as original equipment or retrofitted in the field by cutting and removing trailing edge portions.

The present invention provides a method for diagnosing a neurodegenerative disease or for determining the predisposition of a subject to a neurodegenerative disease. In particular, the methods of the present invention comprise detecting a marker linked to map position 9p21, e.g., a marker within an opioid receptor sigma 1 (OPRS1) gene or an expression produce thereof. The present invention also provides a method for identifying new markers that are associated with a neurodegenerative disease. The present invention also provides mutant forms of an OPRS1 gene or an expression product thereof and reagents for detecting those mutations.

The present invention provides methods for diagnosing a neurological disease and/or for determining the predisposition of a subject to a neurological disease and/or for determining a subject at risk of developing a neurological disease, the method comprising detecting a marker in a glycogen synthase kinase 3β gene or expression product thereof and a microtubule-associated protein tau (MAPT) gene or expression product thereof. The present invention also provides pharmacogenetic methods, e.g., for identifying a subject that will respond to treatment with a therapeutic compound.

This invention provides useful promoters from the R. trifolii nifH gene for the construction of recombinant molecules to regulate foreign genes for expression under desired conditions. In particular, the promoters act to control expression of the foreign genes within root nodules formed by rhizobial bacterial strains in symbiotic combination with host plants.A rhizobium diagnostic segment (RDS) is also provided comprising a DNA segment found at more than one location in rhizobia, the RDS being species-specific, and detectable by DNA hybridization under stringent conditions. A recombinant plasmid comprising a RDS and a bacterial strain containing the plasmid are provided. Methods are provided for identifying species and strains of field isolates of Rhizobium, using RDS's. One RDS exemplified comprises 5' sequences from the R. trifolii nifH gene.
