Preferred Orientation in Microstructures
The microstructures of eutectics between compounds were studied for systems MnO-MnS, NaCl-NaF, NaBr-NaF, LiF-NaF, and FeO-FeS. With the exception of FeS, all the compounds had the NaC1-type structure. In the systems having only NaC1-type structures, the lamellas of the two eutectic phases had matching crystal orientations. There was less consistency among the eutectic systems, however, than bet...
متن کاملPreferred mitotic orientation in pattern formation by vascular mesenchymal cells.
Cellular self-organization is essential to physiological tissue and organ development. We previously observed that vascular mesenchymal cells, a multipotent subpopulation of aortic smooth muscle cells, self-organize into macroscopic, periodic patterns in culture. The patterns are produced by cells gathering into raised aggregates in the shape of nodules or ridges. To determine whether these pat...

LÕanalyse de la texture du sel gemme naturel et du halite dform exprimentalement a montr quÕil se produit une orientation prfrentiel le du rseau dans les cristaux de halite. Les paramtres dÕlasticit pour une srie dÕagrgats polycristallins de halite sont calculs en utilisant les fonctions de distribution dÕorientation.

متن کاملPreferred orientation in experimentally deformed stishovite: implications for deformation mechanisms
Stishovite is a polymorph of SiO2 present in the mantle, making its deformation properties relevant to Earth science. Stishovite was first produced experimentally (Stishov and Popova 1961) and found to have a rutile structure (space group P42/mnm, Stishov and Belov 1962; Sinclair and Ringwood 1978; Ross et al. 1990) with its silicon in octahedral rather than tetrahedral coordination, as is char...
