Abstract: A pre-evacuated container for medical purposes includes an outer body that forms an internal cavity, wherein in a default state the internal cavity is at a vacuum pressure relative to atmosphere, and a fluid interface on the outer body that connects to a drainage tube. A pressure indicator on the outer body is adapted to provide an indication as to a fluid pressure state of the internal cavity. An outlet assembly can be actuated to form an opening between atmosphere and the internal cavity, wherein the outlet assembly can be actuated without damaging the outer body.

Abstract: The invention provides for a heavy truck tire tread having a longitudinal direction, a lateral direction and a thickness direction, said tread comprising : a pair of opposing tread edges (21, 21?) spaced apart along the lateral direction; a tread region extending between the tread edges over a rolling tread width (RTW); a shoulder zone (SZ) adjacent to each tread edge of said pair of opposing tread edges and extending over a lateral length of 10% of the rolling tread width (RTW); and a center zone (CZ) defined between said shoulder zones; wherein the tread region comprises a plurality of ribs (23) separated by grooves (22), said grooves running continuously from the center zone toward each of said tread edges at a groove angle relative to the lateral direction and extending out to the respective tread edge; and wherein a shoulder zone average groove angle is greater than 45° in absolute value; the shoulder zone average groove angle is greater than a center zone average groove angle in absolute values; and the

Abstract: Embodiments of a turbine nozzle having slip joints impregnated by an oxidation-resistant sealing material are provided, as are embodiments of methods for the manufacture of turbine nozzles. In one embodiment, the method includes providing a support ring, a slip joint ring substantially concentric with the support ring and radially spaced apart therefrom, and a plurality of vanes fixedly coupled to the support ring. The plurality of vanes extends radially from the support ring into a plurality of circumferentially-spaced slots provided in the slip joint ring to form a plurality of slip joints therewith. The plurality of slip joints are impregnated with a silicon-modified aluminide sealing material. The silicon-modified aluminide sealing material impedes gas flow into the radial slip joints during operation of the turbine nozzle, while also fracturing to permit relative radial movement between the plurality of vanes and the slip joint ring along the plurality of slip joints.

Abstract: A monomer for use in manufacturing a conjugated polymer, the monomer having a structure as shown formula (2): Ar1, Ar2 and Ar3 are independently selected from optionally substituted aryl or heteroaryl, X1 and X3 both independently comprise a leaving group capable of participating in polymerization and Z represents a direct bond or an optionally substituted bridging atom.

Abstract: In an embodiment, a function call in source code is replaced inline with a body of the function. The body of the function includes a call to a metafunction, first alternative source code, and second alternative source code. The metafunction is evaluated to determine whether a compile-time environment attribute is true. If the compile-time environment attribute is true, the first alternative source code is compiled into object code, where the first alternative source code relies on truth of the compile-time environment attribute. If the compile-time environment attribute is false, the second alternative source code is compiled into the object code, where the second alternative source code does not rely on the truth of the compile-time environment attribute. For example, in an embodiment, the first alternative source code accesses an argument via an address of the argument while the second alternative source code copies the argument to a temporary variable and accesses the argument via the temporary variable.

Abstract: A method, apparatus, system, and signal-bearing medium that, in an embodiment, receive a request to load a class and decide whether debug is enabled for the class. If debug is enabled, a class loader with debug enabled is created. The class and all classes subsequently loaded by the debug-enabled class loader are then kept in interpreted mode. In response to a debug request directed to the class, a determination is made whether a class loader with debug enabled loaded the class. If the class loader with debug enabled did load the class, the debug request is performed; otherwise, the debug request is rejected.
