Abstract: A method for recovery of impurities and/or degradation products and/or heat-stable salts from amine-based solvents used for capture of C02 from gas streams. The method comprises recovering C02 from a C02-enriched amine-based solvent thereby producing a lean amine-based solvent, contacting and mixing together the lean amine-based solvent with a reaction composition comprising a phase-change catalyst and a diluent, thereby producing a first organic phase comprising the impurities and/or degradation products and/or heat-stable salts and a first aqueous phase comprising the lean amine-based solvent, separating the first organic phase and the first aqueous phase; and separately recovering the first organic phase and the first aqueous phase. The organic phase can be regenerated by intermixing with a NaOH solution to form an organic phase comprising therein the reaction composition and and an aqueous phase comprising the NaOH solution with the impurities and/or degradation products and/or heat-stable salts.

Abstract: What is disclosed is a medical device comprising a compressed, cylindrical or oblong, thin-walled, expandable metal structure (a "blockstent") and a flexible, elongated device (a "delivery catheter") to position the compressed blockstent into the lumen of a blood vessel segment to be treated, and methods of use for occlusion of treated blood vessel segments. A blockstent can be made with ductile metals such as gold, platinum, or silver such that the blockstent will conform to the shape of the lumen of the treated blood vessel segment during expansion and allow for the shape of the blockstent to be permanently changed by the application of an external force. The surface of the blockstent can be configured to promote local thrombus on the external surface of the blockstent and to promote the growth of tissue into the wall of the blockstent in order to occlude the treated blood vessel and fix the blockstent in place. The wall of the blockstent can also be configured to release drugs or pharmacologically active molecules such as those that promote thrombosis, cell proliferation, extracellular matrix deposititon to promote this thrombus formation and tissue growth.

Title: Regulation of stomatal apertures by apyrases and extracellular nucleotides
Inventor: ROUX STANLEY J
IPC: A01N63/02
Filed: 2012-06-01
Abstract: The role of extracellular nucleotides and apyrase enzymes in the guard cells that border stomata in regulating stomatal aperture and the plant's resistance to drought and pathogens is disclosed herein. Expression of apyrases APY1 and APY2, in guard cell protoplasts is strongly correlated with cell growth, cell secretory activity and with conditions that favor stomatal opening. Both short-term inhibition of ectoapyrase activity and long-term suppression of APY1 and APY2 transcript levels significantly disrupt normal stomatal behavior in light. Furthermore, two punnoceptor inhibitors in mammals, pyridoxalphosphate-6-azo-phenyl-2', 4 '-disulphonic acid (PPADS) and Reactive Blue 2, block ATPS- and ADPßS-induced opening and closing, and also partially block the ability of abscisic acid (ABA) to induce stomatal closure, and light-induced stomatal opening. Treatment of epidermal peels with ATPyS induces increased levels of nitric oxide and reactive oxygen species, and genetically suppressing the synthesis of these agents blocks the effects of nucleotides on stomatal aperture.

Title: Lockset operable by pivoting actuator about a first axis or a second axis
Inventor: OU XIN BEN
IPC: E05B63/22
Filed: 2014-06-27
Abstract: A lockset is actuable by pivoting a handle about a longitudinal axis of the lockset by rotating the handle and by pivoting the handle about an axis transverse to the lockset axis, such as by pushing or pulling. The lockset includes an inside handle and an outside handle, each associated with an independent mechanism, each of which can independently actuate the lockset.

Abstract: Laminated articles that include a first textile and a functional film layer bonded together by an adhesive layer having a distinctive, discontinuous adhesive pattern is provided. The discontinuous adhesive pattern creates regions free or substantially free of adhesive that permits the laminate to preferentially bend in those regions.  The adhesive regions, together with the non-adhesive regions, create a visible pattern on the surface of the laminate. A second textile may be bonded to the functional film layer opposing the first textile. The first textile or the film layer may be elastic, shrinkable, or expandable. In such embodiments, raised portions of the laminate corresponding to the non-adhesive regions and curled portions corresponding to the adhesive regions are visible. The laminated article is waterproof, liquid-proof, breathable, and aesthetically pleasing and demonstrates a reduction in stiffness, improved insulation properties, improved stretch properties and a reduction of noise associated with bending the article.
