INTRODUCTION osteoarthritis (OA) of knee has been reported as a risk factor for falls and reduced balance in the elderly. This systematic review evaluated the effectiveness of physical therapies in improving balance and reducing falls risk among patients with knee OA. METHODS a computerised search was performed to identify relevant studies up to November 2013. Two investigators identified eli...

Viewshed (or visibility map) computation is an important component in many GIScience applications and, as nowadays there are huge volume of terrain data available at high resolutions, it is important to develop efficient algorithms to process these data. Since the main improvements on modern processors come from multi-core architectures, parallel programming provides a promising means for devel...

The Nasca lines or geoglyphs in southern Peru are known as one of archaeology's greatest mysteries. Since the 1980s, however, new approaches have helped to better understand their function and meaning. The recent photogrammetric recording of 1 500 geoglyphs in the vicinity ofPalpa enabled for the first time a GIS-based analysis. Geoglyph visibility is one of their most discussed traits. While m...

We present an approach to determine the credibility of content provided within a visual VGI source such as Flickr. We propose analysing the variability of selected user and photo metadata of geotagged Flickr photos with the location correctness of these images, which is our reference quality measure. These observed user and photo metadata can help to infer the credibility of contributors.

BACKGROUND AND AIMS Little is known about injuries resulting from accidents in premobile infants. We aimed to describe the pattern of minor accidents in infants and their resulting injuries. METHODS The ALSPAC study collected data in successive postal questionnaires. At 6 months of age, parents were asked to describe any accident since birth. The type of fall, distance fallen, resulting injur...

objectives: this study aimed to identify elderly fallers and non-fallers by balance test under dual tasks conditions. methods & materials: this study was an analyze-comparative study. subjects were from three park of tehran. subjects were 20 older adults with outhistory of falls (aged 75.95±6.28 years) and 21 older adults with a history of 2 or more falls in the previous one year (aged 72.50±7....

the present study explores some physical and chemical parameters in the epilithic diatoms in the water samples obtained from two stations in koçan falls, erzincan from march to november 2014. over the course of the study, 19 taxa of epilithic diatoms were recorded. diatom genera which had the highest number of species in the study period were cymbella (4 species), navicula (4 species), and cycl...

JANUARY 2005 AMERICAN METEOROLOGICAL SOCIETY | ountain snowpack in western North America is a key component of the hydrologic cycle, storing water from the winter (when most precipitation falls) and releasing it in spring and early summer, when economic, environmental, and recreational demands for water throughout the West are frequently greatest. In most river basins of the West, especially in...
