A high-speed photographic film record of a Taylor impact experiment was analysed to determine the strain, strain rate and stress. The stress was calculated on the basis of an interpretive analysis by Taylor involving the motion of a plastic wave in the material. The data on drawn OFE copper produced stresses from 300…
As a chemical indicator, the isomerization rate of so-called 6-SO3−-spiropyran was used to estimate the equilibrium constants for the inclusion complex formation of β- and γ-cyclodextrins (β and γ-CDs). The association constants for inclusion complexes of β- and γ-CDs with various kinds of phenols were determined. It…
We report the formation of an amorphous phase in nanosized Bi particles embedded in an Al-based glassy alloy matrix. High-resolution electron microscopy (HREM) has been used to show that the particles contain crystalline and amorphous portions. A depression of the melting point by more than 100K of the crystalline por…
: Washcoat loading on automotive exhaust catalysts is normally determined, in production, by a weight gain procedure, which gives an accurate measure of washcoat weight present on an individual catalyst but does not address such parameters as uniformity of washcoat loading and geometric surface area within the monolit…
The ARTEMIS BRITE-EURAM program has been presented in this paper. Its main objective is to develop a diagnostic methodology to assess i) the susceptibility of polymeric cable insulation to electrical ageing; and ii) the state of the insulation at any chosen time in order to evaluate the remaining life-time of operatin…
The melting (solidus) temperatures were measured for fuel simulating burnups of 50, 90, 130, 170, 210 and 250 GWd/t (SIMFUEL) which were added non-radioactive soluble fission products (FPs) to unirradiated fast reactor MOX fuel. The melting temperatures for fuels of 250 GWd/t which were blended non-radioactive soluble…
Abstract The size-distribution of ZnS nanoparticles (Q-ZnS) of 4.2 ± 0.6 nm was narrowed to 2.6 ± 0.2 nm by sequential irradiation with monochromatic light of 313 nm, 303 nm, and 297 nm to an air-saturated ZnS colloidal solution in the presence of sodium hexametaphosphate as a stabilizer and methylviologen as an elect…
Internal stresses in tension and compression in an extruded and artificially aged Mg-7.7at.% Al alloy have been determined by in-situ neutron diffraction. Measurements were made on grains having the c axis normal to, parallel to and at 62° from the stress axis, and on the reinforcing phase. The results are consistent…
Convection is an important determinant for both sensible and evaporative heat exchange. Heat transfer by convection for normal boundary conditions is readily described by simple power functions. Clothing affects convection in various ways and existing characterisation of clothing by its static insulation values produc…
An efficient synthesis of alcohol 2 is described from L-Serine (OMe) in four synthetic steps. The process uses readily available reagents and is suitable for manufacturing.
Migration diffusion coefficients of two surfactants (sorbitan laurate, SPAN-20 and sorbitan palmitate, SPAN-40) in polyethylene blend are calculated in the desorption process by means of Fourier transform infrared (FT-IR) spectroscopy technique at 25°C. They are 2.31 and 2.24 × 10−11 cm2/s, respectively, which show no…
Abstract Linearly-polarized-light-induced optical anisotropy of a thin film of polymethacrylate with p-cyanoazobenzenes side chains is enhanced at elevated temperatures to display anomalously high stability toward heat and light.
Abstract— Fluorescence emission from merocyanine 540 (MC540) dimers was observed in dipalmitoylphosphatidylcholine (DPPC) vesicles. This unusual behavior was observed only for vesicles in the gel‐phase state. No dimer fluorescence was observed either in monopalmitoylphosphati‐dylcholine (C 16 PC) micelles or in liquid…
Calculations of atmospheric showers initiated by cosmic rays were carried out using the FLUKA Monte Carlo code. The fluences of various secondary particles, scored at different heights in the atmosphere and at different geomagnetic latitudes, have been converted to effective dose and ambient dose equivalent by means o…
Experimental solubilities are reported for diphenyl sulfone dissolved in 8 alkane, 10 alcohol, and in aqueous solvent media at 25°C. Results of these measurements are used to test the predictive ability of the general solvation model log C A,org sat /C A,aq sat = c + rR 2 + sπ 2 H + aΣα 2 H + bΣβ 2 H + vV x where C A,…
Threshold stress in constant load tests and critical stress in constant strain tests for sulfide stress corrosion cracking (SCC) of seven tubular steels were measured. Percent reduction in area loss caused by SCC of four tubular steels also were measured. Results showed there was no interrelationship among the three p…

This paper considers the objective evaluation of seam puckering on three-dimensional garments. In order to simulate garment surfaces in three dimensions, seamed samples are supported on five different surfaces: plane (both with and without tilt) and curved (both convex and concave). A set of five samples having seams…
The evolution of the brilliance of synchrotron radiation sources has allowed combined functionalities of beamline optics for simultaneous high intensity, rapid tunability and narrow wavelength bandpass. This then combines the chance to measure protein crystal diffraction data at multiple wavelengths for optimized anom…
Three types of tetraazamacrocycles (1,4,8,11-tetraazacyclotetradecane, 1,4,8,12-tetraazacyclopentadecane, and 1,4,8,11-tetraazacyclotetradecane-5,7-dione) are grafted on the surface of phosphorus-containing dendrimers possessing P(S)Cl2 end groups (for generations 1 and 3: this corresponds to three and twelve macrocyc…
