Patterns of death among avalanche fatalities: a 21-year review.
BACKGROUND Avalanches are a significant cause of winter recreational fatalities in mountain regions. The purpose of this study was to determine the relative contributions of trauma and asphyxia to avalanche deaths. METHODS We reviewed all avalanche fatalities between 1984 and 2005 that had been investigated by the offices of the British Columbia Coroners Service and the Chief Medical Examiner...
متن کاملAvalanche fatalities in the western United States: a comparison of three databases
Reported avalanche fatalities in the United States increased markedly through the latter half of the twentieth century, a result of the increasing popularity of winter sports. Despite this increase, the literature concerning US avalanche fatalities is sparse. This paper presents a comparison of three US databases containing avalanche fatality information: Storm Data, the West Wide Avalanche Net...
متن کاملModelling of High Quantum Efficiency Avalanche Photodiode
A model of a low noise high quantum efficiency n+np Germanium Photodiode utilizing ion implantation technique and subsequent drive-in diffusion in the n layer is presented. Numerical analysis is used to study the influence of junction depth and bulk concentration on the electric field profile and quantum efficiency. The performance of the device is theoretically treated especially at the wave-l...
متن کاملAvalanche polynomials
The avalanche polynomial on a graph, introduced in [5], capture the distribution of avalanches in the abelian sandpile model. Studied on trees, this polynomial could be defined by simply considering the size of the subtrees of the original tree. In this article, we study some properties of this polynomial on plane trees. In [5], they show that two different trees could have the same avalanche p...
متن کاملInjuries and Fatalities
For nearly a decade, Purdue’s Agricultural Safety and Health Program has published an annual summary of U.S. grain-related entrapments 2 and engulfments. (www.grainsafety.us). These summaries are based on data gathered, documented, and entered into Purdue’s Agricultural Confined Space Incident Database (PACSID). With support from the U.S. Department of Labor over the past three years, the searc...
