Radiographs of 110 patients who had undergone 120 high tibial osteotomies (60 closed-wedge, 60 open-wedge) were assessed for posterior tibial slope before and after operation, and before removal of the hardware. In the closed-wedge group the mean slope was 5.7 degrees (SD 3.8) before and 2.4 degrees (SD 3.9) immediately after operation, and 2.4 degrees (SD 3.4) before removal of the hardware. I...

background : along with emersion of the internet, virtual education increasingly has been growing. many studies discussed this method and its impact on learning. present study investigated students’ attitude towards virtual education as well as its effect on learning. methods : this was a pretest-posttest quasi-experimental study. the nursing students, who had selected fluids and electrolyte di...

OBJECTIVES We developed virtual-assisted lung mapping (VAL-MAP), a bronchoscopic multispot dye-marking technique using three dimensional (3D) virtual imaging, for precise thoracoscopic sublobar lung resection with safe surgical margins. We herein review the results of 100 consecutive cases of VAL-MAP in our institute to identify types of tumours or resections that benefit from VAL-MAP. METHOD...

A novel MatLab-based diffraction tool for the investigation of scattered fields around a two-dimensional Perfectly Electric Conductor (PEC) wedge is introduced. Analytical (Exact by Integral, as well as some High Frequency Asymptotic (HFA) techniques) and numerical (Finite-Difference Time-Domain (FDTD)) models are included. The FDTD staircase modeling problems are removed by the application of ...

In this paper we study the wedge disclination within the elastoplastic defect theory. Using the stress function method we found exact analytical solutions for all characteristic fields of a straight wedge disclination in a cylinder. The elastic stress, elastic strain, elastic bend-twist, displacement and rotation have no singularities at the disclination line. We found a modified stress functio...

Phylogenetic analysis of bacteria preserved within an ice wedge from the Fox permafrost tunnel was undertaken by cultivation and molecular techniques. The radiocarbon age of the ice wedge was determined. Our results suggest that the bacteria in the ice wedge adapted to the frozen conditions have survived for 25,000 years.

according to the changing business, nowadays teams are cornerstones of successful organizations, in addition, with the developments and technological innovations in communication and information, virtual teams are playing more critical role in today's business. on this basis, determining factors which affect virtual team's performance are important to both scholars and practitioners. ...
