purpose: to evaluate the outocmes and complications of dacryocystorhinostomy (dcr) in the ophthalmic centers of yazd medical sciences university, yazd, iran. method: the outcomes of external dcr (ex-dcr) operation on 187 patients were evaluated. patients were selected consecutively. results: overall success rate was 90.4% (ci 95%; 86.3 - 94.5%). success rate was 90.9% in females and 89.1% in ma...

We present a theoretical and experimental investigation of the effects of a magnetic field on quasi-twodimensional excitons. We calculate the internal structures and dispersion relations of spatially direct and indirect excitons in single and coupled quantum wells in a magnetic field perpendicular to the well plane. We find a sharp transition from a hydrogenlike exciton to a magnetoexciton with...

By performing accurate ab initio density functional theory (DFT) calculations, we study the role of 4f electrons in stabilizing the magneticfield-induced ferroelectric state of DyFeO3. We confirm that the ferroelectric polarization is driven by an exchange-strictive mechanism, working between adjacent spin-polarized Fe and Dy layers, as suggested by Y Tokunaga (2008 Phys. Rev. Lett. 101 097205)...

conclusions although external fixation in open pediatric fractures and severe injuries is recommended, intramedullary nailing is also an effective method with low complications. combining pins and flexible intramedullary nails is effective in developing more stability and is not associated with more complications. background tibial fractures are the third most common pediatric long-bone fractur...

abstract background: adjacent treatment fields are commonly used in external beam radiation therapy, such as mantle and inverted-y fields for the treatment of hodgkin’s disease and craniospinal fields used in the treatment of medulloblastoma and head and neck tumors when the lateral neck fields are placed adjacent to the anterior supraclavicular field. in each of these situations, there is a po...

purpose : to evaluate efficacy, complications, and patient satisfaction using local anesthesia (la), in comparison to with general anesthesia (ga) in external dacryocystorhinostomy (dcr) methods : in this prospective study, 149 patients with complete nasolacrimal duct (nld) obstruction who were candidates for external dcr were randomized in 2 groups: ga 73 patients, and la 76 patients. intraope...

The aim of the study is to develop a non-contact fluxgate position sensor control open /closed state valve. There are many examples use in modern technology elements or devicesthat interact with magnetic field. One most urgent tasks influence magneticfield as means component environment. magnetoopticalsensors for monitoring functioning technical objects due their measure ment method, ability no...

INTRODUCTION The quality of first-responder performance at the end of automated external defibrillator (AED) training may not predict the performance adequately during a real resuscitation attempt. METHODS Between January and December 2000, we evaluated 67 resuscitation attempts in Amsterdam and surroundings, where police officers used an AED. We compared their performance with their assessme...
