It fails, however, to explain the transversal GF(T) data. Both experimental and theoretical data show that nanocrystalline silicon can have an isotropic piezoresistive effect of the order of 40% of the maximum response of crystalline silicon.

“Objective. The purpose of this study was to present a new surgical

preservation technique for teeth with incomplete vertical root fracture.

Study design. Seventeen patients selleck compound with 1 endodontically treated maxillary anterior tooth in which an incomplete vertical root fracture involving only the buccal side was suspected underwent a flap elevation procedure to visualize the pattern of bone loss and assess

the type of root fracture. If the preoperative diagnosis was confirmed, a groove following the fracture line was prepared using retro-tips driven by an ultrasonic device and sealed with mineral trioxide aggregate after filling of the bone defect with calcium sulfate.

Results. A total of 10 vertical root fracture repair procedures were performed. At 12 months’ follow-up, all cases showed PF-6463922 mw clinical and radiographic success. After 33 months, 7 patients were available for a follow-up: 5 cases remained successful, and 2 teeth (lateral incisors) failed.

Conclusions. The present surgical approach for preservation of teeth with incomplete vertical root fracture demonstrated satisfactory results regarding clinical outcome. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010;110:e45-e52)”
“Glossophaga soricina is a widespread Neotropical nectarivorous BTK inhibitor mouse bat. We characterized 10 microsatellite loci isolated from a shotgun genomic library. We analyzed tissues from wing membrane of 67 individuals collected from two populations of Central Brazil (Brasilia and Alto

Paraiso). The number of alleles per locus ranged from 2 to 20, and the observed and expected heterozygosities ranged from 0.015 to 0.666 and from 0.016 to 0.915, respectively. The high combined probability of genetic identity (4.369 x 10(-8)) and probability of paternity exclusion (0.996) showed that these microsatellite loci would be useful for population genetic structure and parentage studies in natural populations of G. soricina.”
“Ab initio calculations, based on pseudopotentials and density functional theory, have been performed to investigate the atomic geometry and electronic structures of calcium fluoride (CaF2) on the Si(001) surface. We have considered the experimentally observed (2 x 1) and (3 x 1) reconstructions with different bonding configurations of the CaF2 molecule on the Si(001) surface. Our total energy calculations suggest that the (3 x 1) structure is slightly more preferable than the (2 x 1). The key structural parameters and electronic surface properties of their most stable structures have been discussed.
