Measurement of the copper to superconductor ratio (Cu/SC) in
composite superconducting wires is necessary for process control, quality
assurance, and characterization of the final wire properties.
A comparison has been made of three techniques for measuring the
Cu/SC ratio on a set of commercial wires produced for the Superconducting
SuperCollider...
Elastic properties of plywood panels are essential for predicting
structural behavior of wood systems. The ASTM Standard D 3043-76
which evaluates the moduli of elasticity (MOE) of plywood, treats
these panels as one dimensional beams instead of two-dimensional
plates, which results in an overestimate of the MOE. Improved procedures
for...
The application of laser generated ultrasonics was first
demonstrated in the mid-seventies and has shown good potential
when applied to isotropic materials. However, its use with
composite materials is still in the early stages of development.
This study explores the potential for application of laser
generated Rayleigh and Lamb waves...
Visualizing large movement datasets with flow maps is difficult because overlapping flows create significant graphical conflicts that make accurate interpretation difficult or impossible. Interactive flow mapping applications allow users to explore large movement datasets by automatically generating flow maps from subsets of the data in response to queries by the...
Frozen Marion (Rubus sp. hyb) and Evergreen blackberries (Rubus laciniatus) (whole berries, berries without seeds, and seeds alone) were acetone/ chloroform extracted. Phenolics were isolated using C₁₈ cartridges and polyamide resins, then characterized and measured by reversed-phase HPLC/diode array spectral techniques. The Polyamide isolated fractions of Marion berries contained four...
Modern geospatial data are frequently represented in some type of three-dimensional (3D) coordinate system, for example geodetic latitude, longitude, and ellipsoid height (φ, λ, h) derived from Global Navigation Satellite Systems (GNSS). But for engineering and surveying work, φ, λ, h coordinates are usually converted to a topocentric system consisting...
The influence of cultivar and maturity on polyphenolic composition and
antioxidant activity was investigated by UV-Visible spectrophotometry and
analytical high performance liquid chromatography (HPLC) in commercially
important blackberry cultivars and selections. The anthocyanin pigments changed
tremendously with ripening. Total anthocyanins increased from 74.7-317 mg/100g
fw from underripe to over ripe...
