This invention relates to catalyst compositions, methods, and polymers encompassing a Group 4 metallocene with bridging eta5-cyclopentadienyl-type ligands, in combination with a cocatalyst and an activator-support. The compositions and methods disclosed herein provide ethylene polymers with low levels of long chain branching.

A can end member (10) has a center panel (18), a circumferential chuck wall, and a transition wall. The center panel is centered about a longitudinal axis (50) and has a peripheral edge. The center panel also has a step portion located radially outwardly from the longitudinal axis. The step portion has an annular convex portion joined to an annular concave portion and displaces at least a portion ...

A method for controlling the temperature of an exothermic reaction and the simultaneous production of steam is based upon the use of heat exchangers (5a) crossed by boiling water along an internal path, extending between an inlet opening (5h) for boiling water and an outlet opening (5f).

The invention relates to methods for predicting the outcome of rectal cancer and stratifying a rectal cancer treatment according to the level of DNA methylation at MINT 1, 3, 12, or 17.

Navigational and optical data are received (102) through interfaces with a navigation unit and a surroundings-acquisition unit. A virtual road marking is determined (104) from the data received. This is a line representing an optimal course to be steered by the vehicle driver when following a curve. The virtual line is shown to the driver in a head-up display, via a further interface (106), in con...

A trailer (1) having a frame (2) defining a loading bed (3); and a number of rubber-tyred steering carriages (4) connected to the frame (2). Each carriage (4) has a respective axle (5); and a respective variable-length, vertical column (27) connected to the axle (5) and hinged to the frame (2) to rotate about and translate along a fixed hinge axis (28). Each axle (5) has a beam (6); and two hubs (...
