Abstract: A method for painting a complex or compound curved three-dimensional surface of a portion of an article. The method comprises providing a paint film; providing sheet metal having opposite major surfaces; laminating the paint film onto a major surface of the sheet metal to form a painted sheet metal laminate comprising a first portion and a second portion; permanently deforming the first portion of the painted sheet metal laminate into a formed portion of the article having a complex or compound curved three-dimensional shape; applying an initial force for securing the second portion of the painted sheet metal laminate during an initial stage of said permanently deforming step; and applying a later force for securing the second portion of the painted sheet metal laminate during a later stage of said permanently deforming step. The later applied force is greater than the initially applied force.

Abstract: A switched reluctance machine has a stator core salient with stator poles disposed concentrically with a rotor that is salient with rotor poles. A plurality of coil windings are wound about the stator core so that a pair of windings are adjacent each of the stator poles. The pair of coil windings induces magnetic flux in the adjacent stator poles and the rotor rotates to align the rotor poles with the stator poles having the induced magnetic flux. The rotor is rotatable at high speeds of up to 50,000 RPM and the coil windings can be directly cooled.

Abstract: This application provides constructs for use as complex cell systems of a desired shape and methods of preparing thereof. The constructs comprise cells contained within a biocompatible gel matrix deposited on a scaffold material optionally cut into defined patterns and impregnated with a crosslinking agent, wherein the biocompatible gel matrix crosslinks upon contact with the crosslinking agent on the scaffold. By stacking multiple alternating layers of the scaffold material cut into defined patterns and the biocompatible gel matrix deposited on the scaffold in defined patterns, complex 3D structures with features like embedded channels are be formed. These complex cell system constructs can be used as in vitro models of biological processes.
Abstract: The present application relates to a method for improving analytical efficiency and cost effectiveness of oxygen isotope analysis of an aqueous sample. In particular, the present application relates to a method of determining an oxygen isotope composition of an aqueous sample by (a) equilibrating the aqueous sample with CO2 gas wherein the aqueous sample comprises an effective amount of carbonic anhydrase (CA) enzyme; and (b) measuring the oxygen isotope composition of the CO2 at equilibrium, wherein the oxygen isotope composition of the CO2 corresponds to the oxygen isotope composition of the aqueous sample.

Abstract: Two isoforms of thyroid receptor alpha (THR?1 and THR?2) have been found to be associated with the growth of cancer. Use of inhibitors of THR?1 (Formula I) and/or agonists of THR?2 (Formula II) in the treatment of such cancers is disclosed. Treatment of other disorders associated with such receptors is also contemplated, as is the use of diagnostic methods for predicting therapeutic outcomes based on the levels of expression of THR?1 and THRa?2 in a tissue sample.
