ZnO thin films were deposited on Si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°C). Dependence of the crystallographic structure, nano-strain, chemical composition and surface physical Morphology of these layers on annealing temperature were studied. The crystallographic structure of films was studied using X-Ray Diffracti...

Metal-Insulator type nano-granular magnetic (NGM) thin films have been noteworthily developed as several functional magnetic materials. The formation of nanogranular structure is strongly related to the magnitude of heat formation (H) of intergranule materials. Forming a larger H allows a clearer granular structure to be obtained. Soft magnetic properties and TMR effect of NGM films are revie...

Changes in nucleolar ultrastructure were studied in preimplantation rat embryos before diapause (d 5), during diapause (d 6, 7 and 8) and after reactivation brought about either by in vitro culture for 24 h (d 7 and 8) or by estradiol-17 beta treatment of the mothers (d 11). Before diapause, fully developed nucleoli contained several low-density fibrillar centers surrounded by a dense fibrillar...

This paper describes an investigation of the influences of chlorine dioxide treatment on fibre surface lignin. The fibre surface characteristics and the interfacial behaviour of the sisal fibre/phenolic resin composites were also studied by SEM, AFM, and XPS. The results show that the surface of the untreated fibre contains a large amount of lignin with granular structure and non-granular struc...

Granular cell tumours are uncommon, generally benign neoplasms of uncertain origin that occasionally affect the tracheobronchial tree. Their incidence seems to be increasing, despite the fact that such tumours are rarely suspected on clinical grounds or bronchoscopic appearance. Here we describe three cases of endobronchial granular cell tumours, one of which regressed spontaneously after biops...

Granular cell tumors are predominantly benign, occurring more commonly in women, with about 10% developing in the gastrointestinal tract. Rectal location of this tumor is very rare. We herein report one such case of a 61-year-old man with granular cell tumor in the rectum who underwent endoscopic curative resection.

Many alpine torrents convey regularly debris flows of high destructive hazard. After several granular events observed in Bruchji’s torrent near the Blatten village in the Swiss Alps, it was decided to manage the risk of similar debris flows by designing and constructing a control structure inside the torrent bed. Associated with a breach in the right bank side of the torrent, this control struc...
