Retractable type fall arresters are part of the equipment used for protecting people against falls from a height. They are an intermediate part between full body harness worn by a man and the structural anchor at the worksite. The most important task of retractable type fall arresters is to arrest people's falls and to reduce their harmful consequences. Information received from users as well a...

in order to evaluate phenological characteristics, yield and yield components of 18 cold tolerant lentil genotypes in fall planting under supplementary irrigation, an experiment was carried out based on randomized complete block design in 2006-2007 at research farm of college of agriculture, ferdowsi university of mashhad. irrigation was performed three times: immediately after sowing, 20 days ...

BACKGROUND Annually, 35-40% of those aged >65 years fall; up to 5% of such falls result in fracture. Fracture is determined both by propensity to fall and by bone fragility. AIM To determine osteoporosis prevalence and predictors in patients who have fallen. DESIGN Observational cross-sectional study. METHODS We measured calcaneal BMD in 408 consecutive patients aged >50 years attending a...

Height field ray tracing is one approach to photorealistic visualization of terrain. Parametric methods, which fall into a new class of height field ray trace methods, are introduced 1. The height field is horizontally sliced into evenly spaced cross-sections. For each cross-section, the Euclidean distance from each point to the nearest point where the slice cuts through terrain is computed off...

Seat height that is too high (> 120% of lower leg length [LLL]) or too low (< 80% of LLL) can impede safe transfer and result in falls. This study examines the difference between LLL of frail nursing home residents and the height of their toilets and beds in the lowest position, compares the patient or environmental characteristics of those able to transfer from the bed or toilet to those who c...

OBJECTIVES In several epidemiological studies of maxillofacial trauma, falls were one of the most frequent causes of facial injury. The aim of this study is to analyse the patterns of fall-related maxillofacial injuries based on the height of the fall. MATERIAL AND METHODS Using a systematic computer-assisted database of patients hospitalised with maxillofacial fractures, only those with fall...

AIM To assess the risk factors, mechanism of injury, and clinical outcome of hospitalized patients with spinal injuries in order to recommend preventive measures. METHODS Patients with spinal injuries admitted to Al Ain Hospital, United Arab Emirates (UAE) for more than 24 h or who died after arrival to the hospital were studied over 3 years. Demography, location and time of injury, affected ...

BACKGROUND We evaluated the demographic data, mortality rates, fall causes, and post-mortem findings of individuals who fell from heights. METHODS Five hundred thirty-eight patients who sustained injuries after an accidental fall from heights were entered into the study. Our cases were collected prospectively in Batman over a seven- month period. RESULTS The mean age was 12.4+/-3.22 years (...
