Nanocrystalline nc materials are known to deform via mechanisms not accessible to their coarse-grained counterparts. For example, deformation twins and partial dislocations emitted from grain boundaries have been observed in nc Al and Cu synthesized by severe plastic deformation SPD . This paper further develops an earlier dislocation-based model on the nucleation of deformation twins in nc fac...
We present a case of inferior conjunction in a rare type of conjoined twins, dicephalus in a male fetus. The male fetus was born to a 24-year-old, gravida 2, and para 0, who had medical abortion at 15 weeks of gestation due to anencephaly with meningoencephalocele revealed by ultrasound examination. The fetus was born with 2 anencephalic heads with a bifurcation of the vertebral column and pres...
The extensive literature dealing with radiographic changes in bones during normal development is concerned principally with the time at which epiphysial centres appear and the ages at which they fuse with the diaphyses. Little attention has been paid to the appearance and form of these epiphyses soon after they have become radio-opaque. This paper directs attention to the frequent occurrence of...
A highly efficient and stable biocatalyst (denoted D201_Lac) was fabricated by encapsulating Trametes versicolor laccase within a macroporous and strongly basic exchange resin D201 through a simple adsorption process. Transmission electron micrographs and Fourier transform infrared spectra of the resultant D201_Lac proved that nanosized laccase clusters were embedded into the inner nano-pores/c...
Gc-ms Analysis of Phytochemicals in the Methanolic Extract of Cyclea Peltata. (lam) Hook.f & Thomson
Cyclea peltata is locally called as “kariballi” belongs to the family Menispermaceae. It is a twining shrub, traditionally used in the treatment of wounds, skin infections and muscular sprains by local folk medicinal practioners. The present study was designed to determine the phytochemical compounds in the methanolic extract of Cyclea peltata by GC-MS analysis. GC-MS chromatogram of the methan...
Introduction My PhD research focuses on the social context of cloth from the Neolithic to Bronze Age with case studies from the Alpine area. One aspect of this is the interrelationship of the technologies used to create flexible, thin sheets of material that can be wrapped, folded, shaped and tied. This includes fibre-based cloth such as textiles, netting and twining as well as animal skins (le...
the aim of this study was to evaluate the effect of glycogenic diets supplemented with different poly unsaturated fatty acids on reproductive performance of iran black ewes in two different managing programs. ewes were allocated in two different groups; group a (n = 75) and group b (n = 25). ewes from group a were stopped from suckling followed by introducing to the rams on days 80 and 90, resp...
