Abstract: A method for sealing a gas turbine engine includes coupling a turbine bucket to a rotor wheel and forming an interface region therebetween. A cooling air passage is defined in a portion of the rotor wheel and a cooling air manifold is defined in a portion of the turbine bucket. The method also includes inserting a seal tube within at least a portion of the cooling air passage. The method further includes coupling the cooling air passage, the seal tube, and the cooling air manifold in flow communication to at least partially define a turbine bucket cooling system. The method also includes operating the gas turbine engine such that the rotor wheel and the turbine bucket are rotated, thereby inducing a pressure on the seal tube to substantially decrease air flow discharged from the turbine bucket cooling system through the interface region.

Abstract: Application-level replication, the synchronization of data updates within a cluster of application servers, may be provided by having application servers themselves synchronize all updates to multiple redundant databases, precluding the need for database-level replication. This may be accomplished by first sending a set of database modifications requested by the transaction to a first database. Then a message may be placed in one or more message queues, the message indicating the objects inserted, updated, or deleted in the transaction. Then a commit command may be sent to the first database. The set of database modifications and a commit command may then be sent to second database. This allows for transparent synchronization of the database and quick recovery from a database failure, while imposing little performance or network overhead.

Abstract: The invention provides a system and method for integrating petroleum system and geomechanical computer models for use in oil and gas exploration. In one embodiment, the invention provides a petroleum system model capable of analyzing data relating to a subterranean formation and calculating the geometry and geochemistry of each layer of the formation through geologic time. The present invention also provides a geomechanical model in communication with the petroleum system model such that information concerning each layer of the subterranean formation may be shared and cross-referenced as an iterative operation prior to the analysis of subsequent layers. At each step of the iterative operation, results are calculated, validated, and cross-referenced in order to produce improved reliability estimates of petroleum charge and mechanical seal integrity for the subterranean formation.

Abstract: According to one general embodiment of the present invention, there is provided a computer program product for reducing incidence of errors in connections between a power consumer apparatus operable to draw a load and a power supply apparatus capable of varying the power supplied, the computer program product comprising: a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising: computer readable program code configured to generate at the power consumer apparatus an identifiable pattern in a load to be drawn from a power supply connection to a power supply apparatus; and computer readable program code configured to monitor at the power consumer apparatus for a change in the load corresponding to the pattern, the monitoring being performed across a signal connection to the power supply apparatus; wherein a positive result of the monitoring indicates a correct configuration. Additional embodiments are also presented.

Abstract: A composition comprising, per litre of aqueous solution, from 30 to 350 g polyethylene glycol, from 3 to 20 g of an ascorbic acid component selected form the group consisting of ascorbic acid, a salt of ascorbic acid, or a mixture thereof, an alkali metal or alkaline earth metal sulphate, preferably from 1 to 15 g thereof, and optionally one or more electrolytes selected from sodium chloride, potassium chloride, and sodium hydrogen carbonate, and preferably also comprising flavourings, is effective in cleansing the gut in preparation for a endoscopy, especially colonoscopy. It is safer than conventional sodium phosphate-based gut cleansing compositions, and hence can be used for patients who would be at risk with sodium phosphate-based compositions, and is better tolerated than conventional PEG-based compositions, leading to better patient compliance and enabling effective out-patient use.

Abstract: A Communications system for communicating over low bandwidth or high latency links incorporates a router MR7 configured to route a message to any like-configured router MR8, MR9 linked to it. Communications are implemented at network layer with UDP IP message packets. There are no hello messages. The message format 20 includes routing information but not designated and backup routers, which avoids loss of service from designated router changes and reduces bandwidth requirements. Configured routers MR7 to MR9 have different message formats 20, 40 for communicating with configured routers MR7 to MR9 and with unconfigured routers R1 to R6 respectively, and can link different protocols. A configured router MR7 deletes routes to like-configured routers MR8, MR9 with route metrics not superior to other routes with like destination. It also deletes routes with inferior metrics to related routes in an incoming message, and retains received route information regarding a new route or a route with superior metric.
