“We have studied the polarization-electric-field hysteresis, the dielectric permittivity dispersion, the piezoelectric PXD101 in vivo properties, the electric-field-induced strain, and the interrelations between these properties for bismuth ferrite (BiFeO3) ceramics. The results indicate that the domain-wall movement in BiFeO3 is strongly inhibited by charged defects, most probably acceptor-oxygen-vacancy defect pairs. The domain-wall find more mobility can be considerably increased by preventing the defects from migrating into their stable configuration; this can be achieved by thermal quenching from above the Curie temperature, which freezes the disordered defect state. Similarly, Bi2O3 loss during annealing at high temperatures contributes to depinning of the domain walls and an increase in the remanent polarization. The possible defects causing the pinning effect are analyzed and discussed. A weakening of the contacts between the grains in the ceramics and crack propagation were observed during poling with constant field at 100 kV/cm. This is probably caused by an electrically induced
strain associated with ferroelastic domain reversal. A relatively large piezoelectric d(33) constant of 44 pC/N was obtained by “”cyclic poling,”" in which the electric field was released after each applied cycle with the purpose to relax the mechanical
stresses and minimize the problem of cracking. (C) 2010 American Institute of Physics. [doi:10.1063/1.3490249]“
“The aim of the study was to evaluate the clinical and functional outcomes of laparoscopic sacrocolpopexy, in particular Nocodazole in vitro its effect on female sexual function.
A retrospective observational study of women undergoing laparoscopic sacrocolpopexy between February 2005 and March 2009 was undertaken. Pelvic organ support was assessed objectively using the pelvic organ prolapse quantification scale (POP-Q). Functional outcomes were assessed using the International Consultation on Incontinence questionnaire for vaginal symptoms (ICIQ-VS), both preoperatively and at 6-36 months postoperatively.
Eighty-four women with a mean age of 65 years (range, 49-78 years) were studied. At follow-up in clinic, all women had good vault support (mean point C, -8.9; range, 10 to -8). Subjective improvements in prolapse symptoms and sexual well-being were observed with significant reductions in the respective questionnaire scores.
Our results confirm previous findings that laparoscopic sacrocolpopexy is a safe and efficacious surgical treatment for post-hysterectomy vaginal vault prolapse.
