conclusions penetrating trauma from wooden fragments provides a diagnostic challenge. a stubborn discharge from a wound must always raise the suspicion of retained fragment. early and appropriate surgical exploration is imperative. introduction in contrast with victims of major trauma, patients who suffer minor injuries receive little specialist input. in most cases, this causes no difficulty, ...

Portable chainsaws are associated with substantial risk and can cause serious injury to operators, especially during kickback. This paper presents new results from research and analyses conducted regarding the impact between the different properties of wood on this occurrence. In an open area, such differences may include: wood species, humidity, temperature and the facing angle of the wood fib...

The thermal characteristics and kinetics of coal, biomass (pine sawdust) and their blends were evaluated under combustion conditions using a non-isothermal thermogravimetric method (TGA). Biomass was blended with coal in the range of 5-80 wt.% to evaluate their co-combustion behaviour. No significant interactions were detected between the coal and biomass, since no deviations from their expecte...

BACKGROUND Wood smoke inhalation causes severe ventilation and oxygenation abnormalities. We hypothesized that smoke inhalation would cause lung injury by 2 mechanisms: (1) direct tissue injury by the toxic chemicals in the smoke and (2) a mechanical shear-stress injury caused by alveolar instability (ie, alveolar recruitment/derecruitment). We further postulated that alveolar instability would...

INTRODUCTION The purpose of this study was to describe factors of possible importance for the occurrence of hand injury from powered wood splitters. PATIENTS Patients were identified by a computerized patient registry. Information was obtained from hospital records, a written questionnaire and a structured telephone interview. RESULTS Very few splitters were constructed according to Europea...

Selection of frost tolerant cultivars and understanding the mechanisms of frost hardiness could help to improve freezing resistance in olive plants. Olive cultivars may differ in frost hardiness due to differential survival of specific organs. The aim of this study was to screen different olive cultivars based on their stomatal density and metabolic modifications under cold conditions. The ‘Zar...
