PURPOSE This retrospective study tests if runners who habitually forefoot strike have different rates of injury than runners who habitually rearfoot strike. METHODS We measured the strike characteristics of middle- and long-distance runners from a collegiate cross-country team and quantified their history of injury, including the incidence and rate of specific injuries, the severity of each i...

on 26 december 2003 at 05:26lt (01:26gmt), a catastrophic earthquake mw 6.6, seismic moment (6 – 9 ×10 nm) struck the city of bam in the kerman province of southeast iran. the intense shaking in the city caused the complete collapse of nearly every building in the central parts of the city including many of the newer buildings, killing about 40000 people officially. the city lies to the east of...

The focus here is on the paradoxical finding that whereas visually perceived egocentric distance is proportional to physical distance out to at least 20 m under full-cue viewing, there are large distortions of shape within the same range, reflecting a large anisotropy of depth and frontal extents on the ground plane. Three theories of visual space perception are presented, theories that are rel...

This paper looks at voice source correlates of declination. This follows a line of research that proposes that prosody is primarily signalled by the temporal modulation of the voice source, and not just F0. Inverse filtering and source parameterisation was carried out on twelve 3-accent sentences of Connemara Irish (Declaratives, WH questions and Yes/No questions). All have a falling intonation...

BACKGROUND In the Plio-Pleistocene, the hominin foot evolved from a grasping appendage to a stiff, propulsive lever. Central to this transition was the development of the longitudinal arch, a structure that helps store elastic energy and stiffen the foot during bipedal locomotion. Direct evidence for arch evolution, however, has been somewhat elusive given the failure of soft-tissue to fossiliz...

ABSTRACT In 1829 James Dunlop published the first southern double star catalogue of some 253 stars. The accuracy this has been determined by using Aladin to cross-match them with Gaia DR2 and estimate their positional (right ascension, declination, position angle, separation) magnitude accuracy. Seven per cent could not be identified 14 were single We found 13 stars (5 cent) currently listed in...

In this paper a simulation to maximize the global solar radiation on a sloped collecting surface was applied to typical latitudes in the area of southern Italy, to calculate the optimum tilt angle of solar panels on building structures or large photovoltaic power plants located in that geographical area. Indeed, the area of southern Italy and in particular Sicily and Calabria are the top of Eur...

Subtalar distraction bone-block arthrodesis for malunited calcaneal fractures was performed in 31 patients (26 men, five women), with a mean age of 38.5 years. The mean time from injury to arthrodesis was 36 months. There were no cases of nonunion. One patient had an early dislocation of the bone block requiring a repeat arthrodesis, and one had a soft-tissue infection. The mean AOFAS hindfoot ...
