in this study, the development of structural elements and the relationship between these elements and dikes emplacements investigated by the field surveys and analysis of satellite images of the east dasht-e bayaz fault zone. in this area nnw-sse (t2) and nw-se trending dikes are which follow the fractures of the region. we measured geometric characters of dikes (such as thickness, attitude, di...

We have performed experiments on the laboratory scale to image seismic wavefronts of compressional waves that are guided between parallel fractures. The wavefronts are detected using water-coupled 1MHz piezoelectric transducers. The stiffness of the fractures is controlled by applying radial stress in a hydraulic stress apparatus that leaves the observation face of the fractured sample open to ...

UNLABELLED Femoral neck fractures occur in approximately 6,000 of young adults annually (ages 18-49) (1). Of these, a high-energy traumatic event is the typical cause. Although medications and chronic diseases have been implicated as confounding causes of hip fractures, clinicians should have a high index of suspicion for an oncologic etiology of hip fractures occurring in young patients withou...

Sacral fracture commonly results from high-energy trauma. Most insufficiency fractures of the sacrum are seen in women after the age of 70. Fractures of the sacrum are rare and generally combined with a concomitant pelvic fracture. Transverse sacral fractures are even less frequent which constitute only 3-5% of all sacral fractures. This type of fractures provide a diagnostic challenge. We repo...

Intracapsular fracture neck of femur have always presented great challenges to orthopaedic surgeons and remain in many ways today the unsolved fracture as far as treatment and results are concerned Intracapsular fractures are devastating injuries that most often affect the elderly. Intracapsular fractures are very rare in young individuals with normal bone. The incidence of intracapsular fractu...

Background: To examine whether interobserver reliability, decision-making, and confidence in decision-making in thetreatment of distal radius fractures changes if radiographs are viewed on a messenger application on a mobile phonecompared to a standard DICOM viewer.Methods: Radiographs of distal radius fractures were presented to surgeons on either a smart phone using a mobilemessenger applicat...

background: considering the importance of an early diagnosis and proper decision-making in regards to the treatment of pediatric distal radius and elbow fractures, this study examines emergency medicine specialists’ accuracy in the diagnosis and treatment of these patients. methods: from 2012 and 2013, children less than 14 years old who were referred to an academic hospital emergency departmen...
