    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.

    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.
