Estimating the fracture density of small-scale vertical fractures when large-scale vertical fractures are present
When fractures are vertical, aligned and their dimensions are small relative to the seismic wavelength, the medium can be considered to be an equivalent Horizontal Transverse Isotropic (HTI) medium. However, geophysical data acquired over naturally fractured reservoirs often reveal the presence of multiple fracture sets. We investigate a case where there are two vertical sets of fractures havin...
متن کاملVertical fractures of the dens.
PURPOSE To establish the mechanism of injury that causes vertical fractures of the dens. METHODS Over a 3-year period, 30 patients with dens fractures were seen at our institution. From these records, we identified and retrospectively reviewed the radiographs (n = 3), CT scans (n = 3), and MR images (n = 1) of three patients with vertical fractures of the dens to assess the characteristics of...
متن کاملThe histopathogenesis of vertical root fractures.
Fractured roots were examined histologically, using different stains, to study the morphological fracture patterns and to identify potential irritants. Fractures were usually, but not always, complete and extended from a surface to include the root canal. The potential irritants identified in both the fracture space and communicating canal were bacteria, necrotic tissue, food debris, and uniden...
متن کاملTiros Vortices and Large - Scale Vertical Motion
TIROS cloud photographs and fine-scale quasi-geostrophic calculations of vertical motion are used in an attempt to gain understanding of the evolution of vortices and other aspects of large-scale cloud masses and to explore the usefulness of the pictures in diagnosis of the vertical motions. Horizontal and vertical motions are found to be of roughly equal importance in the cvolution of cloud pa...
متن کاملNonoperative Management of Vertical C2 Body Fractures.
OBJECTIVE To estimate the incidence and to describe the clinical results of the nonoperative management of vertical C2 body fractures. METHODS An 8-year retrospective review of upper cervical spine injuries from the registry of a level I trauma center identified 21 patients with a vertical C2 body fracture. RESULTS Sixteen coronally oriented Type 1 vertical C2 body fractures and 5 sagittall...
