Abstract:
A manufacturing process produces a stabilizer bar having a thickened, reinforced portion formed by thermal spraying a molten metal onto a surface of the bar. The process produces a stabilizer bar having a thickened portion in the areas typically subject to fatigue failure while avoiding the addition of unnecessary material and weight to other locations of the stabilizer bar not needing reinforcement. In one example, the unprocessed bar stock is thermally sprayed in desired locations. The thermally sprayed bar is formed into a desired shape and heat treated. The heat treated, formed, and sprayed bar is shot peened. Alternatively, the bar is thermally sprayed after the surface has been prepared by shot peening. Forming of the bar may also occur before thermal spraying, and pretreated bar stock may also be used.
Abstract:
Embodiments of the present invention provide methods and nucleic acid reporter molecules for the detection of nucleic acid in a sample. The nucleic acid reporter molecule comprises two unsymmetrical cyanine monomer moieties, which may be the same or different, that are covalently attached by a linker comprising at least one aromatic, heteroaromatic, cyclic or heterocyclic moiety comprising 3-20 non-hydrogen atoms selected from the group consisting of O, N, S, P and C. The linker may be rigid, relatively flexible or some degree thereof. The unsymmetrical cyanine monomer moieties comprise a substituted or unsubstituted benzazolium moiety and a substituted or unsubstituted pyridinium or quinolinium moiety that is connected by a methine bridge that is monomethine, trimethine or pentamethine. The linkers form the cyanine dimer compounds by attaching to the pyridinium or quinolinium moiety of the monomer moieties. The present nucleic acid reporter molecules find utility in forming a nucleic acid-reporter molecule complex and detecting the nucleic acid. In particular, present nucleic acid reporter molecules with a rigid linker and monomer moieties with a monomethine bridge find utility in detecting RNA in the presence of DNA.

C. by warm finish rolling in the single phase ferrite region below A.sub.rl to effect ferrite dynamic recrystallization of the steel microstructure to a ferrite structure of grain size having a grain size of up to 5 .mu.m, and especially an ultra fine grain size of 1 to 2 .mu.m; the method may be employed in various hot working methods including strip and rod mills, planetary hot rolling and extrusion.
Abstract:
A series of thermomechanical workings such as temperature-controlled torsional strains are applied to a specimen of steel at strain and temperature levels and interpass times selected to simulate rolling mill conditions. The measured stress values are compared with the temperatures of the steel during the working periods during which the respective values were obtained. Thermomechanical working schedules are repeated at selected varying starting and terminating temperatures thereby to obtain a series of possible rolling schedules. These simulations are selected so that a varying number of reduction passes in the sequence occur at steel temperatures below temperature A.sub.r3. The value of a selected parameter of the worked steel, e.g. yield strength, is measured at ambient temperature. From the rolling mill analogue of possible rolling schedule simulations, an optimized rolling schedule is selected which will predictably impart to the steel a value of the selected parameter falling within a predetermined range. Linear regression analysis is applied to empirically obtained rolling mill data to derive one or more linear relationships between a selected property (e.g. yield strength) of the steel and rolling mill parameters thereby to permit selection of an optimum rolling schedule suitable to obtain a preselected value of the selected property of the steel.

Abstract:
The invention provides a novel class of cyanine dyes that are functionalized with a linker moiety that facilitates their conjugation to other species and substituent groups which increase the water-solubility, and optimize the optical properties of the dyes. Also provided are conjugates of the dyes, methods of using the dyes and their conjugates and kits including the dyes and their conjugates.
Abstract:
Chemically reactive carbocyanine dyes incorporating an indolium ring moiety that is substituted at the 3-position by a reactive group or by a conjugated substance, and their uses, are described. Conjugation through this position results in spectral properties that are uniformly superior to those of conjugates of spectrally similar dyes wherein attachment is at a different position. The invention includes derivative compounds having one or more benzo nitrogens.

Abstract:
The present invention provides methods for determining the presence of immobilized nucleic acid employing unsymmetrical cyanine dyes that are derivatives of thiazole orange, a staining solution and select fluorogenic compounds that are characterized as being essentially non-genotoxic. The methods comprise immobilizing nucleic acid, single or double stranded DNA, RNA or a combination thereof, on a solid or semi solid support, contacting the immobilized nucleic acid with an unsymmetrical cyanine dye compound and then illuminating the immobilized nucleic acid with an appropriate wavelength whereby the presence of the nucleic acid is determined. The cyanine dye compounds are typically present in an aqueous staining solution comprising the dye compound and a tris acetate or tris borate buffer wherein the solution facilitates the contact of the dye compound and the immobilized nucleic acid.
