The heat and mass transfer model developed in Part I has been further modified to evaluate the steaming of blended and interleaved fabric-wrapper assemblies. Various conditions relating to the batch decatizing of a wool fabric with a cotton, nylon, or polyester wrapper have been examined. Results of the computations s…
Measurements of dislocation resistivity and the deviations from Matthiessen's rule (DMRs) are reported for polycrystalline Cu samples with various dislocation densities, impurities and phonons. Since this DMR can reach the same order of magnitude as the dislocation resistivity itself, its quantification is essential i…
Abstract The behaviour of three typical thermoplastic polymers—polypropylene (PP), polyamide 6 (PA‐6), ABS and PP mixed with inert talc or fire retardant magnesium hydroxide or melamine—was assessed in the Cone Calorimeter and in traditional widely used tests. It is seen that the evaluation of the relative fire hazard…

A comparative study of the liquid crystal and ferroelectric properties of several achiral, racemic and non-racemic 2,6-naphthyl benzoates and their 1,4-phenyl benzoate analogues is reported. In terms of pure compounds, both central core structures give rise to similar mesophase sequences; however, the naphthalene deri…
Weathering of serpentinitic parent material, naturally rich in both Cr and Ni, provides soils that generally contain elevated concentrations of both metals. In this study, soil development as well as the fate of Cr and Ni in Dystric Eutrochrepts derived from serpentinitic rock slide material were investigated in the S…
Abstract Ring‐closing depolymerization of poly(ε‐caprolactone) in toluene solution with catalytic amounts of Bu 2 Sn(OMe) 2 results in a mixture of cyclic oligomers, the equilibrium concentration of which corresponds to the concentration predicted according to the Jacobson‐Stockmayer theory. ε‐Caprolactone, however, i…

Abstract The X-ray crystal structures of the two black, isotypic, mixed valent solids In 4 Te 3 ( a = 15.619(1) Å, b = 12.749(1) Å, c = 4.4348(3) Å, space group Pnnm , Z = 4) and In 4 Se 3 ( a = 15.296(1) Å, b = 12.308(1) Å, c = 4.0806(5) Å), were redetermined using single crystals isolated from homogeneous, microcrys…
The intracellular phospho-alpha(1,1)glucosidase TreA from Bacillus subtilis has been overproduced in Escherichia coli and purified by ion-exchange chromatography and gel filtration. The molecular mass, estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, was 64 kDa. Isoelectric focusing indicated ho…

Neutron irradiation uniformly produces vacancies and interstitials in silcon carbide (SiC) poly crystals, and the specimen swells by 1 to 3%. Subsequent isochronal annealing leads to annihilation of the defects by the interstitial-vacancy recombination from around irradiation temperature, resulting in the shrinkage of…

Since the introduction in the 1970s of single paste composite materials, there has been a rapid increase in the range of both materials and activation light units. This investigation is being undertaken as part of a larger study where the characteristics of both composite materials, light activation units and composit…

We investigate the stability of a disk to magnetic interchange in the disk plane, when a poloidal magentic field provides some radial support of the disk. The disk is assumed to be geometrically thin and may possess rotation and shear. We assume the unperturbed magnetic field vertically threads the disk and has a comp…
Barium titanate ceramic samples, obtained by sol‐gel methods, having different grain sizes have been analyzed by diffuse phase transition techniques. We performed a study of the influence of each method on the phase transition interval and on the Landau parameters of the ferroelectric phase transition of these materia…
Through selective cultivation with 6-aminohexanoate linear dimer, a by-product of nylon-6 manufacture, as the sole source of carbon and nitrogen, Pseudomonas aeruginosa PAO, which initially has no enzyme activity to degrade this xenobiotic compound, was successfully expanded in its metabolic ability. Two new enzyme ac…
The electrochemical oxidation‐dissolution of (111) silicon has been investigated in solutions. Four electrons per silicon were observed per oxidized silicon. Current doubling (quantum efficiency of 2.2) was observed for the photo‐oxidation of n‐Si. Unlike the etching of (111) silicon in aqueous solutions, no pores wer…
