It is common for subsurface flow to transition between porous and fractured media. Two examples include vertical infiltration of precipitation through a permeable soil overlying a fractured bedrock, and horizontal ground water flow through a combination of porous and fractured geologic units. A reduction in flow or flow impedance may occur across these interfaces caused by head losses associate...

For the purpose of clarifying seismic response characteristics fractured-cavity reservoirs Dengying Formation in central Sichuan Basin, paper first intends to establish three geological models fracture cave based on drilling, logging, and core data Basin. Then, formation reflection is calculated with reference anisotropic Horizontal Transverse Isotropy (HTI) medium. Finally, further research Am...

The humeral head articulates with the glenoid fossa of the scapula. The anatomical neck separates the greater and lesser tuberosities from the humeral head. The long head of biceps runs between the tuberosities in the bicipital groove, and the surgical neck is just below the greater and lesser tuberosities. The radial nerve runs posteriorly around the middle third of the humeral shaft in the sp...

Impact of Induced Thermal Stresses during Circulation Tests in an Engineered Fractured Geothermal Reservoir: Example of the Soultz-sous-Forêts European Hot Fractured Rock Geothermal Project, Rhine Graben, France — The wider concept of hot fractured rock geothermal energy is put forward to overcome the natural limitations of classic geothermal fields. A suite of numerical modules based on a disc...

An analysis of 4,045 implants placed in function during a 5-year period yielded eight fractured implants (0.2%). All fractures had associated marginal bone loss. The majority (six of eight) were supporting posterior prostheses. Parafunctional habits were diagnosed in all patients with fractured implants. Most patients presented with loosening or fracture of prosthetic gold screws or abutment sc...

for the characteristics of horizontal fractures in shallow low-permeability oil layers after hydraulic fracturing in multilayer reservoirs, horizontal fractures are taken equivalent to an elliptical cylinder with the reservoir thickness using the equivalent permeability model; then, upon the elliptic seepage theory, the seepage field which has led by a vertical well with horizontal fractures is...

STUDY DESIGN Cohort study. PURPOSE The aim of this study is to propose and evaluate a new technique to assess bone mineral density of fractured vertebrae using quantitative computed tomography (QCT). OVERVIEW OF LITERATURE There is no available technique to estimate bone mineral density (BMD) at the fractured vertebra because of the alterations in bony structures at the fracture site. MET...
