The present invention provides a novel method and a system of modules for carrying out thermal analysis of cast iron melts. The characterizing step of the method is de-termination of the position of the thermocouples used for recording cooling curves. The system comprises a thermocouple unit, a thermocouple holder, and a sampling unit. The system comprises means for ensuring that the thermocouples are correctly positioned before starting the thermal analysis. The system also comprises means for automatically transferring calibration data regarding the thermocouples.

The present invention relates to the detection of promoter methylation status using a combination of either modification of methylated DNA or restriction endonuclease digestion, multiplex polymerase chain reaction, ligase detection reaction, and a universal array or capillary electrophoresis detection.

A behavioral monitoring system useful for the analysis of complex behaviors in a number of animal species. The monitoring systems of this invention allow continuous monitoring of feeding, drinking and movement of animals with high temporal and spatial resolution. In certain embodiments, the system comprises an enclosure comprising: an animal position indicator; a food consumption indicator; and a fluid consumption indicator, where the system reports behavioral data at a temporal resolution of 20 seconds or lower.

We have developed a particular combination of elements and devices which enables the portability of a scanning electron microscope (SEM). In particular the combination enables a small size, typically less than about 50 liters, a manageable weight, typically less than about 15 kg, and a low power requirement, typically less than about 100 W, which permits operation using power supplied from a portable source such as a battery. Higher performance versions may exhibit increased volume in the range of about 150 liters, increased weight, in the range of 45 kg, and a power requirement in the range of 300 W. The higher performance version of the portable scanning electron microscope may be portable with the assistance of a dolly (rolling cart) or with the assistance of attached wheels and pulling appendage.

Disclosed are new acridone dye derivatives having characteristic fluorescence lifetimes. Also disclosed are methods for labelling target biological materials employing the acridone dyes and use of the labelled materials in biological assays. The acridone derivatives have the following structure:in which Z1 and Z2 represent the atoms necessary to complete one ring, two fused ring, or three fused ring aromatic or heteroaromatic systems, each ring having five or six atoms selected from carbon atoms and optionally no more than two atoms selected from oxygen, nitrogen and sulphur; R2, R3, R4 and R5 are selected from hydrogen, halogen, amide, hydroxyl, cyano, nitro, mono- or di-nitro-substituted benzyl, amino, mono- or di-C1-C4 alkyl-substituted amino, sulphydryl, carbonyl, carboxyl, C1-C6 alkoxy, acrylate, vinyl, styryl, aryl, heteroaryl, C1-C20 alkyl, aralkyl, sulphonate, sulphonic acid, quaternary ammonium, the group -E-F and the group —(CH2—)nY; R1 is selected from hydrogen, mono- or di-nitro-substituted benzyl, C1-C20 alkyl, aralkyl, the group -E-F and the group —(CH2—)nY; where E is a spacer group, F is a target bonding group; Y is selected from sulphonate, sulphate, phosphonate, phosphate, quaternary ammonium and carboxyl; and n is an integer from 1 to 6. The invention also relates to a set of different fluorescent acridone dye derivatives, each dye having a different fluorescence lifetime, the set of dyes being particularly useful for multiparameter analysis.

The present invention relates to compositions, devices and methods for detecting microorganisms (e.g., anthrax). In particular, the present invention provides portable, surface-enhanced Raman biosensors, and associated substrates, and methods of using the same, for use in rapidly detecting and identifying microorganisms (e.g., anthrax).
