Abstract The influence of the addition of two ethylene‐propylene random copolymers (EPM) with different composition on the mechanical properties, thermal behavior and overall morphology of high density polyethylene (HDPE)/isotactic polypropylene (iPP) blends, was investigated on extruded samples. The experimental data…

Abstract An improved cube method has been developed for calculating the intensity of diffuse x‐ray scattering of macromolecules in solution using a certain set of their atomic coordinates. The technique is based on the ideas of B. Lee and F. M. Richards [(1971) J. Mol. Biol. 55 , 374–400] and Richards [(1977) Annu. Re…

Reliable blood-brain transfer constants can be determined from data obtained in single-time experiments (i.e., a single experimental time for tissue sampling). The accuracy of such measurements depends on factors such as the test molecule used and the experimental time chosen; therefore, the selection of optimal exper…

Abstract Electrical conductivity in magnetite has been studied experimentally as a function of temperature and oxygen activity between 560 and 1400°C. The results indicate that above T C (=575°C) an octahedral site small polaron mechanism is dominant over the entire temperature range ( E a = 0.1136 eV). By comparing d…

Elastic compliance measurements are reported in $\mathrm{K}{\mathrm{Ta}}_{1\ensuremath{-}x}{\mathrm{Nb}}_{x}{\mathrm{O}}_{3}$ mixed crystals exhibiting a concentration-dependent ferroelectric phase-transition temperature ${T}_{c}$. For concentrations $x\ensuremath{\ge}0.008$, an anomaly is observed at ${T}_{c}$ in the…

Recent calculations on coincidence twist grain boundaries in oxides with the rocksalt structure have shown that the interfaces are only weakly bound. This is in contrast with experiment in which twist grain boundaries have been observed in MgO. The static lattice relaxation calculation presented here predicts a restru…

Dislocation behaviour in fatigued copper single crystals with [123] and [111] fatigue axes has been investigated dynamically by in situ experiments with a high-voltage electron microscope to clarify the origin of persistent slip bands (PSBs) and how the ladder structure is formed. From observations of the fatigued [12…

Atomistic simulation methods have been used to calculate the structures end energies of a series of 〈001〉 symmetrical tilt grain boundaries in NiO. The configurations studied were all coincident twin boundaries, but the relaxation displaces the two crystal halves from the perfectly coincident structure. The (n 10) bou…

The methyl-accepting chemotaxis proteins (MCPs) of Escherichia coli undergo reversible methylation that has been correlated with adaptation of cells to environmental stimuli. MCPI, the product of the tsr gene, accepts methyl groups at multiple sites that are located on two tryptic peptides, denoted K1 and R1. A second…
