In order to study the effects of factors governing the bioabsorption rate of polylactides, implantation tests were carried out in rabbits using various samples (20 x 10 x 2 mm3) differing in their chemical composition, residual monomer content, and molecular orientation. Copolymer samples with a higher lactic acid con…
The orientation distribution function (ODF) of the crystallites of polycrystalline materials can be calculated from experimentally measured pole density distribution functions (pole figures). This procedure, called pole-figure inversion, can be achieved by the series-expansion method (harmonic method). As a consequenc…

A1 (purity, 99·7%) with 0·1 or 2 mm grains was torsionally deformed at 400°C and 0·2s-1 up to equivalent strains of 60. Tangential sections were examined by polarized light, transmission electron microscopy and scanning electron microscopy. The grains wound into helicoids with an axial thickness varying inversely with…
An interactive program, POWD, written in Fortran77, for powder diffraction data interpretation and indexing is described. Various functions such as the least-squares refinement and the systematic absence test are also included in this versatile program. The modified de Wolff figure of merit [Wu (1988). J. Appl. Cryst.…
Peptidylarginine deiminase (proteinarginine iminohydrolase, EC 3.5.3.15) converted some arginine residues to citrulline residues in soluble vimentin, in a micromolar Ca2+-dependent manner and resulted in the loss of polymerization competence of the intermediate filament protein. When about 8 mol of residues/mol of vim…
The lattice model for linear polymeric glasses proposed by Gibbs and Di Marzio several decades ago is used to calculate the average relaxation time for the structure of the model as a function of temperature. Using the fact that the model exhibits the existence of a temperature ${T}_{0}$ for which the configurational…
The pressure drop and wetting film thickness for isolated bubbles and bubble trains moving in circular and square capillaries are computed. An arclength-angle formulation of a composite lubrication equation allows for the numerical matching of the lubrication solution of the transition region to the static profiles aw…

By means of a gas‐tight electrochemical cell, oxygen permeation measurements have been performed on the oxygen ion conductor 8 mole percent (m/o) yttria‐stabilized zirconia, as a function of T (800°–1050°C) and p O 2 (0.21–10 −17 atm). Ionic conductivity was measured by the conventional four‐probe method. The followin…

Geometric measure theory is the mathematical framework for the study of crystal growth, clusters of soap bubbles, and similar structures involving minimization of energy. Morgan emphasizes geometry over proofs and technicalities, and includes a bibliography. This Second Edition features a new chapter on soap bubbles.
Etude experimentale de la variation de la durete en fonction de la grosseur de grain pour des materiaux nanocristallins. En contraste avec la relation de Hall-Petch, cette analyse, realisee sur le cuivre et le palladium a la temperature ambiante, montre un decroissement de la durete lorsque la grosseur de grain decroi…
The present review deals with the latest achievements in the chemistry of ionic melts and liquid crystals (LC). New liquid crystals, formed by salt melts containing organic ions, have been described. The characteristics of their thermodynamic and transport behaviour, structure, and optical properties have been examine…
The third-order optical susceptibility of the Pt, Pb, and metal-free tetrakis(cumylphenoxy)phthalocyanines was measured by degenerate four-wave mixing at 1.064 μm, far from strong absorption bands. Metal substitution strongly enhances the off-resonant χ(3). The χ(3)xxxx for Pt-phthalocyanine (2×10−10 esu) and Pb phtha…
