Abstract: In an aspect, the invention is directed to a set of game pieces including a character game piece representing a character and a plurality of parameter impact game pieces. Each of the parameter impact game pieces includes a parameter impact indicator. When a parameter impact game piece is stacked on the character game piece the parameter impact indicator provides a graphic representation of the parameter impact carried out by the parameter impact game piece. When another parameter impact game piece is stacked on the first parameter impact game piece a graphic representation of the total parameter impact carried out by both parameter impact game pieces is provided by permitting the parameter impact indicators from both parameter impact game pieces to be visible to the players. In this way, the parameter impact level incurred by the character can be shown to increase incrementally after subsequent parameter impacts.

Abstract: A propulsion drive system is operated by a controller to propel an industrial vehicle along a path in an unmanned mode. An autonomous processor module sends commands to the vehicle controller in response to messages received via a communication network from a guidance and navigation system. The guidance and navigation system transmits a message over the communication network, wherein that message contains a first numerical value specifying the velocity and a second numerical value specifying an amount that the propulsion drive system is to turn a wheel of the industrial vehicle. The message also specifies a maximum speed limit and indicators commanding that a load carried by the industrial vehicle be raised and lowered. The autonomous processor module transmits a feedback message indicate actual vehicle operating parameters to the guidance and navigation system.

Abstract: Provided is a method for preventing the elution of Bi from copper alloy, in which the elution of Bi is prevented in leadless copper-alloy plumbing equipment and the like containing a trace of lead and a predetermined amount of Bi. The present invention relates to a method for preventing the elution of Bi from copper alloy in which at least Bi present on the surface of copper alloy containing Bi is selectively removed by preferentially dissolving Bi in a 4 to 20 mass% concentration of nitric acid while suppressing Cu dissolution. Furthermore, elution of Pb is suppressed using a 10-20 mass% concentration of nitric acid. In this case, by removing at least Bi present on the surface of copper alloy containing Bi using nitric acid and then treating the surface of the copper alloy by shot-blasting corrosive products, such as oxides, produced from the nitric acid are removed, and gloss is imparted to the surface.

IPC: F01D25/12
Filed: 2013-03-11
Granted: 2020-03-10
Abstract: A system for cooling a generator mounted in the tail-cone of an engine. The system comprises a fairing, which receives through an inlet thereof air from a bypass duct and directs the bypass air towards a cavity of the tail-cone for cooling the generator. The bypass air is then expelled through an outlet of a support strut positioned in fluid communication with the tail-cone cavity. The fairing inlet and the strut outlet are both positioned in a plane substantially perpendicular to a longitudinal plane of the engine. In this manner, circulation of the bypass air through the fairing, the tail- cone cavity, and the strut may be achieved. The bypass air directed through the fairing further enables cooling of service lines accommodated in the fairing. A lobe mixer is further used to direct the fairing and shield the latter from core exhaust.

Abstract: La présente invention concerne un système et un procédé pour charger le médicament anticancéreux de première intention, la doxorubicine (DOX), sur des nanoparticules d'or coiffées d'ADN dont l'ADN double brin a été conçu pour intercalage spécifique de DOX. Étant donné que chaque AuNP contient environ 108 sites de médicament à affinité élevée, cette conception permet d'atteindre une concentration locale élevée de DOX sur la particule. La liaison du médicament est confirmée par contrôle de l'augmentation de la température de fusion de l'ADN, du déplacement du maximum de résonance des plasmons, et de l'augmentation du rayon hydrodynamique NP en fonction du rapport [DOX]/[ADN]. L'applicabilité des nanoparticules en tant que système d'administration de médicament a été mise en évidence en montrant que la DOX liée aux particules peut être transférée vers un ADN cible.
