OBJECTIVE Posterior longitudinal ligament reduction (PLLR) has been widely used for treatment of thoracolumbar burst fractures. However, there are no systemic studies assessing the influence of position parameters of intra-canal fracture fragment (IFF) itself on outcome of reduction. The aim of this study was to analyze the relationship between position parameters of IFF and the reduction effic...

In this note, we show that a finite collection of stable subgroups of a finitely generated group has finite height, finite width and bounded packing.

The tree-layout problem is to compute the coordinates of nodes of a tree so that the tree, when drawn on a piece of paper, appeals to human understanding. The tree-layout problem, which seems inherently sequential at the first glance, can be solved by a data-parallel algorithm. It takes O (height * log width ) time on width pro33333333333333333333333333333 This work was supported in part by Nat...

OBJECTIVES The aim of this study was to compare nostril height, width, collumelar length, interalar distance and nostril symetry between unilateral complete cleft lip/palate patients undergoing nasoalveolar moulding (NAM) and incomplete cleft lip patients/palate with no need of presurgical moulding before and after cheiloplasty with primary nasal correction. Our study group included 18 patients...

1. Body-weight, body height, knee width, wrist width and skinfold measurements were made on males (n 139) and females (n 167) in three age-groups (20-22, 25-27 and 30-32 years). Percentage of body fat was calculated from skinfold thicknesses using regression equations according to Durnin & Womersley (1974). Three indices of relative weight were calculated: W/H2, W/Hp and W/W, where W is body-we...

anthropometry is the study of human body dimensions and proportions among different races. in work environments, poorly designed workstations and tools reduce productivity and can lead to fatigue and musculoskeletal injuries. this study aimed to determine the anthropometric characteristics of iranian workers in comparison to three other asian countries. this cross-sectional study evaluated 400 ...
