Let us introduce the notation used throughout the paper. For any notions related to convexity in this paper, consult R. Schneider [8]. We write o to denote the origin in the Euclidean space En, and ‖ · ‖ to denote the corresponding Euclidean norm. Given a set X ⊂ En, the affine hull and the convex hull of X are denoted by affX and convX , respectively, moreover the interior of X is denoted by i...

Loops of non-absorbable sutures were used to extend the recession of the horizontal recti in 27 patients. All patients had horizontal squints and were considered unsuitable for conventional recession/resection procedures. The technique is described and the results are evaluated.

OBJECTIVE This study evaluates the cost-effectiveness of 5-aminolevulinic acid (5-ALA, Gliolan®) in patients undergoing surgery for malignant glioma, in standard clinical practice conditions in Spain. MATERIAL AND METHODS Cost-effectiveness ratios were determined in terms of incremental cost per complete resection (CR) and incremental cost per additional quality-adjusted life year (QALY), bas...

Post-traumatic orbital reconstruction remains a surgical challenge and requires careful preoperative planning, sound anatomical knowledge and good intraoperative judgment. Computer-assisted technology has the potential to reduce error and subjectivity in the management of these complex injuries. A systematic review of the literature was conducted to explore the emerging role of computer-assiste...

in this paper, a new cascaded multilevel inverter by capability of increasing the number of output voltage levels with reduced number of power switches is proposed. the proposed topology consists of series connection of a number of proposed basic multilevel units. in order to generate all voltage levels at the output, five different algorithms are proposed to determine the magnitude of dc volta...

background: the most efficient application of ionizing radiation is serving medical purposes and using this radiation has caused people to learn that artificial sources of radiation exposure among these resources can be of highest exposure rate.   objective: the present study is aimed at initially establishing a baseline for local-reference dose level in mazandaran, iran in 12 projections of th...

a total of 60 neck skin swab samples were taken from 12 different broiler flocks after the chilling stage of processing at a commercial broiler slughtering facility in mashhad. the presence of salmonella was assessed by conventional culture method and confirmed by using poly o and poly h antiserum in serotyping. pcr amplification of inva gene as a specific method for detection of salmonella was...

introduction: video-assisted clinical instruction (vacid) has been found to be a beneficial teaching tool for various fields in dentistry. the aim of this interventional study was to compare the efficacy of live conventional demonstration (cd), video teaching, and vacid (video with explanation) methods in teaching of root canal treatment to undergraduate dental students. methods and materials: ...

abstract methods of tillage and organic matter affect root growth and distribution and therefore nutrient uptake by plant and its growth. this study was performed consecutive two years. tillage treatments included disk harrowing + two disk harrowings as reduced tillage (15 cm plowing depth) and moldboard plowing + two disk harrowings as conventional tillage system (30 cm plowing depth). also, t...
