Abstract: A power transmission system for an aircraft turbine engine including a speed reducer including a ring gear that is able to rotate about an axis X, formed from half-rings having annular flanges clamped together by first fastener. The reducer includes an annular channel for recovering centrifuged oil, having a U-shaped cross section, extending around the flanges, this channel being formed by an axial assembly of at least two parts and forming a fairing for the flanges and the first fastener intended to limit aerodynamic disturbances.

Abstract: A damper for an object is placed in a medium subjected to vibrations. The damper has an idle state in the absence of vibrations, a first operating state in case of vibrations of a first type, and a second operating state in case of vibrations of a second type. The level of each vibration of the first type is less than the level of each vibration of the second type. The damper includes an outer support structure, an inner support structure, and at least one pair of membranes formed of a first membrane and a second membrane. Each membrane is formed of a viscoelastic material including fibers aligned substantially in a same direction.

Abstract: An extracellular domain of CD19 (CD19-ECD) which comprises at least 90% sequence identity to SEQ ID NO:1, a first core region at positions 2-98 of SEQ ID NO:1, a second core region at positions 167-258 of SEQ ID NO:1, a third core region at positions 99-166 of SEQ ID NO:1, and at least one stabilizing point mutation at an amino acid position within said first and/or second and/or third core regions, wherein the CD19-ECD has an increased thermal stability compared to CD19-ECD which consists of an amino acid sequence identified as SEQ ID NO:1.
