Atomistic calculations of the core structures of six different nonscrew 1 / 2 (111) dislocations lying on a (110) plane have been made using three different central inter-atomic forces. The cores of all the dislocations studied have been found to be similar: planar, confined to a single (110) plane. The results are, t…

Abstract Secretion of the exoskeleton of Thecidellina barretti proceeds in the same way as in other living brachiopods, but the structure of the mantle edge is different. Mucin cells occupy the core of the outer mantle lobe, and periostracal secretion begins within a slot separating lobate cells charged with secretion…

The results of single-zone annealing of 76 samples of Pb1−xSnxTe are reported, covering the entire composition range from pure PbTe to pure SnTe. Some of the sample preparation work overlapped and improved on the work of others, while some of the results, particularly in the alloy samples, are new. Annealing times, te…

It is well established that open-end yarns are different from ring yarns; in particular OE yarns are weaker and more bulky in spite of the higher twist levels used. The introduction of these yarns into woven fabric affects the structure and the characteristics of the fabrics. The fabric structure traps non-load bearin…

The metal-to-insulator transition in V2O3 is described by a model that is based on the electronic band structure of this material. The vanadium 3d-t 2g band decomposes in the trigonal symmetry into two bands, a 1g and e π. The a 1g band consists of orbitals connecting pairs of c-axis neighbouring atoms, while the e π…

Summary The residua system of chemical weathering is here defined as the chemical sink towards which the bulk of earth's surface materials (i.e. the silicate rocks) trend during weathering. Chemically the system is defined in terms of four major components, SiO 2 –Al 2 O 3 –Fe 2 O 3 –H 2 O, evidence being derived from…
