  • Patent number: 11415061
    Abstract: A power distribution device between an electric starter of a turbomachine and an electric machine toward a shaft of the turbomachine, including the electric starter, the electric machine, and a controller for controlling the electric machine. An epicyclic train reducer includes a first element intended to be coupled to the shaft, a second element coupled to the electric starter, and a third element intended to be rotated by the electric machine. The controller is configured to rotate the third of the three elements so as to obtain two bearings of reduction ratios of the speeds between the first of said three elements and the second of the three elements. The controller is configured to drive the torque of the third of the three elements in accordance with a determined output torque.

  • Publication number: 20110306055
    Abstract: The present invention provides a novel method for diagnosing, monitoring, prognosing and staging Lymph Node (LN) status in colorectal cancer (CRC) that is more sensitive and accurate than conventional detection technologies such as histopathology. The Guanylyl Cyclase C (GCC) gene is specifically expressed in apical epithelial cells of the GI tract from the duodenum to the rectum and the detection of GCC mRNA in LNs is indicative of the presence of metastases. Quantitative RT-PCR (RT-qPCR) detection of GCC mRNA to identify the presence of colorectal cancer (CRC) cells in LNs has the potential to aid in CRC staging. When used in combination with glucuronidase B (GUSB), accurate quantification of GCC can be achieved with less than a 2-fold variation between intact and highly degraded RNA specimens.

  • Patent number: 6561198
    Abstract: In this method for the surface treatment of a metal part (12) for the purpose of deoxidizing it and/or cleaning it, a sealed chamber (16), in which the part to be treated is placed, is filled with a low-pressure reducing gas mixture, a static magnetic field is created in a region of the chamber (16) separate from the region in which the part (12) to be treated is placed and the gas mixture is excited by means of an electromagnetic wave injected into the chamber (16) so as to generate a treatment plasma in the gas, the intensity of the static magnetic field corresponding to electron cyclotron resonance established in the chamber in a distributed manner.
