Test flange assemblies comprise a flange body and a piston. The piston is configured to translate relative to the flange body and has an outer surface facing away from the flange body and an inner surface facing toward the flange body. The outer surface defines a circular seal channel for receiving a seal structure between the piston and a flange surface of a flanged component. The outer surface radially inward from the circular seal channel has a surface area that is less than a surface area of the inner surface. Methods of testing pressure containing structures comprise operatively positioning the test flange assembly, positioning a seal structure within the circular seal channel of the piston, coupling the flange body to a flanged component, and pressurizing a volume between the piston and the flange body so that the piston compresses the seal structure between the piston and the flanged component.

Featured is a method for reducing frequency of taking background spectra in FTIR or FTIR-ATR spectroscopy. Such a method includes determining if there is a pre-existing reference spectrum available and if such a reference spectrum is available, acquiring a present reference scan before acquiring a sample scan. The method also includes comparing the present reference scan with the pre-existing reference spectrum to determine if there is one or more non-conformities therebetween and if there is/are one or more nonconformities, determining if the one or more non-conformities are resolvable or not. If the one or more non-conformities are resolvable; resolve each non-conformity in a determined manner and thereafter acquiring a scan of the sample, and if the non conformities are not resolvable, then acquiring a new reference sample and thereafter acquiring a scan of the sample.

Global trends force industry to manufacture lighter, safer, more environmentally-friendly, more performant, and cheaper products. Due to its excellent thermal and electrical conductivity, copper is widely used in heating and cooling equipment and electrical devices. The rising demand caused the copper price to increase significantly. Solving the conflict between the technological benefits arising from the excellent properties of copper and the disadvantages regarding cost and weight is possible by substituting current full copper parts by copper-aluminium hybrid parts. Within JOINEM, such components will be produced by electromagnetic pulse welding (EMW). EMW is a high-speed joining technology using pulsed magnetic fields. The joint is formed without heat, but due to the impact of the joining partners. Disadvantages associated with conventional technologies are avoided and high-quality dissimilar material combinations can be joint. In JOINEM, strategies for the process and tool design shall be developed for joining copper-aluminium connections and for 2 other specific material combinations. Profile-shaped components as well as sheet metal applications will be regarded. For joint optimisation, surface preparation, design of the joint geometry, and other aspects will be investigated. A multi scale simulation strategy will be developed for determination of acting loads, deformation, impacting conditions, joint formation, and load capacity of the joint. Designing durable and efficient tools is an indispensable prerequisite for the industrial implementation of the technology and will be addressed in the project. The applicability of the process design strategy shall be validated based on industrial applications. Process and equipment design strategies will be evaluated in an industrial setting. This includes automation and quality control, economic efficiency calculations, life-cycle, and recycling issues, to demonstrate and quantify the advantages of EMW.

Described herein are methods, devices and systems for simple organization, visualization and use of genome data (e.g. human genome data) on electronic devices (e.g. portable devices). In some embodiments, the data are organized and/or visualized according to phenotype traits, genes, and/or markers in a similar manner to the organization and/or visualization of digital music contents. This concept allows a new procedure for genomic data organization and facilitates the development of genomic data visualization tools. The methods described herein can be implemented with consumer-oriented software on electronic devices, computers, and portable devices, for the use of genomic related data in the field of personalized medicine for predictive, preventive and participative wireless healthcare.

A centralizer for centralizing a pipe is provided which collaborates the spring force of its bow springs. The centralizer includes a pair of end collars, and at least one center collar. Each of the collars has a center hole for coaxially receiving a pipe. In addition, the centralizer includes a plurality of longitudinally extending and arcuate bow springs having ends which affix to the end collars. The centralizer includes linkage arms which connect the center collar to the bow springs. The linkage arms may provide additional outward spring force against the bow springs. Preferably, the centralizer includes a mechanism for forcing the bow springs radially inward from their at rest position.

The embodiments of the present invention are directed to applying intimate contact pressures to samples while undergoing ATR infrared interrogation. As a general mode of operation, after a solid sample is placed on the ATR element, a force actuator moves an anvil arm to apply a contact force to the sample against the ATR. Thereafter, when the scan is over, the user can see the result of the one or more scans. The force actuator may be a motor or a solenoid or other type of force actuator. The applied contact force may be a fixed force or may be a user-selectable force or may be automatically controlled through feedback from the spectrometer based on the spectroscopic signature of the sample material.

A method of identifying the presence of heroin in an impure heroin composition which contains heroin and at least one fluorescent contaminant which interferes with a Raman signal from the heroin. The method may include contacting the mixture with a solvent such as an alcohol, then contacting the resulting alcohol composition with a SERS surface. The surface may then be exposed to laser light from a hand-held Raman spectrometer to detect a Raman signal from the heroin. An apparatus for performing the method is also provided.
