Background: Knee malalignment is an important modifiable cause of osteoarthritis (OA). Surgical therapeutic procedures depend on proper knee alignment assessment. The purpose of this study was to compare knee alignment parameters between double and single leg weight-bearing radiographs and to evaluate the reproducibility of inter- and intra-observer measurements. Methods: One hundred eight p...

Background and Objectives: Food insecurity may be associated with poor nutrition, which in turn can increase the risk of adverse nutrition and health outcomes among infants and toddlers. This study was undertaken in 2008 to gain an insight of mothers' views on complementary feeding practices and food security. Materials and Methods: In this qualitative study, data were collected through 10 Foc...

A study on the public's perceptions and conceptions of global environmental changes (GECs) is relevant to guide future educational strategies and management actions. The present study aimed to: (1) evaluate coastal tourists' conceptions and perceptions of GECs; (2) correlate the conceptions presented by tourists about GECs and their self-declared knowledge; (3) evaluate how these tourists perce...

We demonstrate the importance of anisotropic neutrino radiation in the mechanism of corecollapse supernova explosions. Through a new parameter study with a fixed radiation field of neutrinos, we show that global anisotropy of the neutrino radiation is the most effective mechanism of increasing the explosion energy when the total neutrino luminosity is given. We discuss the reason why, and demon...

An approach to the problem of organization in human action is presented. The approach describes the observable forms of behavior in terms of the dynamics of task specific devices (TSD). The properties of a TSD delineate problems for research. The properties are task specificity, smartness, determinism, soft assembly and reduction, controllability, scale specificity, assembly over properties of ...

background: the i-space is a radiological imaging system in which computed tomography (ct)-scans can be evaluated as a three dimensional hologram. the aim of this study is to analyze the value of virtual reality (i-space) in diagnosing acute occult scaphoid fractures.   methods: a convenient cohort of 24 patients with a ct-scan from prior studies, without a scaphoid fracture on radiograph, yet ...

An important predictor of historical sound change, functional load, fails to capture insights from speech perception. Building on ideal observer models of word recognition, we devise a new definition of functional load that incorporates both a priori expectedness and perceptual information. We explore this new measure with a simple model and find that it outperforms tra-
