The rutschblock test is one of the most reliable snow stability tests. It is a mini slab avalanche that is tested with the appropriate dynamic load: the skier or snowboarder. The test method and its limitations are reviewed. The application of the rutschblock test as the standard stability test in the observational network of the Swiss Avalanche Warning Service is described. Introduction The ru...

The aim of this paper is to compute the rational character tables of the dicyclic group $T_{4n}$, the groups of order $pq$ and $pqr$. Some general properties of rational character tables are also considered into account.The aim of this paper is to compute the rational character tables of the dicyclic group $T_{4n}$, the groups of order $pq$ and $pqr$.

INTRODUCTION The clavicle, humerus and acromioclavicular (AC) joint separately are very commonly involved in traumatic injuries around the shoulder. Acromioclavicular joint dislocation with distal clavicle fracture is a well recognized entity in clinical practice. AC joint dislocation with mid shaft clavicle fracture is uncommon and only few cases have been reported in literature. However, to t...

Introduction: The occurrence rate of hip fractures due to osteoporosis is rapidly increasing, representing one of the most serious and urgent social problems. We focused on a computed tomography-based finite element method (CT/FEM) to quantify structural strength, thereby developing a nonlinear CT/FEM to achieve accurate assessment of strength of the proximal femur [1]. The aim of this study wa...

it has been reported that fractures are more common in epileptic patients relative to the general population. seizures by repeated muscular contractions can increase fracture risk throughout the skeleton, but the reported papers about non traumatic vertebral fractures following a single episode of seizure are rare and mostly located in thoracic spine with only one or two vertebral fracture. the...

background: the main purpose of this study was to determine the relationship between serum vitamin d and the status of bone mineral density in patients with low-energy hip and distal radius fracture. methods: this retrospective case-control study was performed between january 2013 and january 2014. participants aged 55 years or older were divided to case group including 85 patients with low-ene...

this article aims to review various modes of fracture toughness of resin composites. also, this study intends to review the papers on the fracture mode, namely “fractography”, under scanning electron microscopy finding fracture initiation site, and the effect of filler content on the fracture toughness of resin composites. it will also review the effect of aging on the fracture toughness of res...
