Introduction: The aim of this study was to determine the accuracy of digital panoramic radiography in estimating the crestal width of implant fixtures after surgery. Materials and Methods:We selected 241 digital panoramic images after implant insertion which had documented information of their actual size. The crestal width was measured on radiographs. We compared two measuring methods in diff...
Results 862 pts (63±10y, 69% male); 57% OPCAB. Median ES II=1,12%; ES I=2,45%. Observed mortality was 2,9%. OPCAB pts had lower glucose, higher ejection fraction, less previous surgeries, less LMCA lesions, smaller bleeding and less distal anastomosis (3,2±1,2 x 3,8±1,0, p<0,001). They had similar use of LITA (89,8% x 86,2%, p=0,102) and complete revascularization (94,9% x 94,5%, p=0,820). In b...
Invariant numerical schemes possess properties that may overcome the numerical properties of most of classical schemes. When they are constructed with moving frames, invariant schemes can present more stability and accuracy. The cornerstone is to select relevant moving frames. We present a new algorithmic process to do this. The construction of invariant schemes consists in parametrizing the sc...

For optical waveguides with high index-contrast and sharp corners, existing full-vectorial mode solvers including those based on boundary integral equations typically have only second or third order of accuracy. In this paper, a new full-vectorial waveguide mode solver is developed based on a new formulation of boundary integral equations and the so-called Neumann-to-Dirichlet operators for sub...
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
rested on sociocultural theory (sct), this study attempted to examine the effect of written corrective feedback (wcf) followed by producing written languaging on developing writing accuracy over new tasks. to this aim, two intact iranian efl classes at the low-intermediate level were randomly assigned to two experimental groups: direct (n = 25) and indirect (n = 25). both groups wrote on a numb...
