Interchangeable accessory for removable attachment to garments including attachment and interchangeable sections. The attachment section formed by an inner peripheral ring with interspersed inner and outer ridges, an outer peripheral ring with concavity at an inner-edge surface, and a gap between the outer peripheral ring and the inner peripheral ring for interference fitting. The interchangeable section being a plug with inside and outside peripheral edges which form a cylindrical extension from the plug surface, the inside peripheral edge configured to snap-fit onto the inner ridges, and a cap including an inner circumferential tab having an inner periphery dimensioned smaller than the outer peripheral edge of the plug such that the cap is connectable to the plug in a removable manner.

A glass molding system and a method of making glass articles using the glass molding system are disclosed. The glass molding system includes an indexing table, a plurality of enclosures arranged along the indexing table, and a plurality of stations defined on the indexing table such that each of the stations is selectively indexable with any one of the enclosures. At least one radiant heater is arranged in each of the enclosures. A radiation reflector surface and a radiation emitter body are arranged in each of the enclosures. The radiation emitter body is between the at least one radiant heater and the radiation reflector surface and has a first surface in opposing relation to the at least one radiant heater and a second surface in opposing relation to the radiation reflector surface.

An apparatus for thermally debinding a cellular ceramic green body includes a duct preferably defined between a first housing and a second housing. A carrier assembly for the green body is adapted for arrangement within a channel such that the green body is positioned between a first portion of the channel and a second portion of the channel. The apparatus further includes a nozzle positioned to inject gases from the duct into a first portion of the channel and a recirculation fan positioned to draw gases out of a second portion of the channel and discharge the gases into the duct. Also described is a carrier assembly including a base support comprising a plurality of spaced stringer beams having spaces between adjacent ones; and a plurality of ring supports including openings, said ring supports mounted on, and bridging the spaces between, the stringer beams, the ring supports having a surface adapted to support the green body.

摘要:
Methods for the selection of novel signaling allosteric DNA enzymes are provided. In particular, fluorescent signaling allosteric DNA enzymes are described. The selection system is based on the cleavage of an ribonucleotide flanked by a fluorophore modified nucleotide and a quencher modified oligonucleotide. Both cis-acting and trans-acting allosteric DNA enzymes are identified, as well as aptamer/DNA enzyme conjugates.

Thermodynamically stable solutions of chalcogenide-bound Ln compounds with one or more Ln ions coordinated or bound by chalcogenolate, chalcogenide or polychalcogenido ligands by means of the ligand chalcogenide atom, wherein the Ln compounds are dissolved at a level up to about 90 vol.% in a host solvent optically transparent to wavelengths at which excitation, fluorescence or luminescence of the Ln ions occurs.
摘要:
Methods for the selection of deoxyribozymes that are active at selected pH ranges are provided. The method comprises detection of a ribonucleotide cleavage event. The detection of catalysis is coupled to the generation of a fluorescent signal. Novel deoxyribozymes which are capable of performing catalysis at pH3, pH4, pH5, pH6 and pH7 were isolated using the methods of the present invention.
摘要:
A method for fabricating a green ceramic article containing organic compounds. The method involves first heating the green ceramic article to sequentially remove the organic compounds such that the organic compound with the lowest weight loss onset temperature is substantially removed prior to the next higher weight loss onset temperature organic compound. The organic compounds include but are not limited to at least an oil or oil-based compound having a flash point or an ignition temperature, higher than the weight loss onset temperature. For this system the temperature during heating is maintained below the flash point of the oil or oil-based compound until substantial removal thereof from the green ceramic structural body. After the organic compounds are substantially removed, the green ceramic article is further fired to a temperature and for a time to obtain a final fired body.
