The incidence of a fractured humeral head penetrating into the thoracic cavity is extremely rare. A 46-year-old woman presented with moderate respiratory distress at the emergency department after being involved in a motor vehicle accident. Radiographic examinations revealed fractures of the second to fifth ribs on the left side along with hemopneumothorax and fracture-dislocation of the humera...

Two and three dimensional finite element models (FEM) were developed to simulate the behavior of a fractured jaw bone and the fixation materials. Mini-plates with various geometric and material properties and screw combinations were considered. Their effects on the variation of maximum stress contours were investigated. The geometric and material properties of the plate, screw and bone were see...

Based on the field measurements of the physical properties of fractured rocks, the anisotropic properties of hydraulic conductivity (HC) of the fractured rock aquifer can be assessed and presented using a tensor approach called hydraulic conductivity tensor. Three types of HC values, namely point value, axial value and flow direction one, are derived for their possible applications. The HC valu...

A numerical method as well as a theoretical study of non-Darcy fluid flow through porous and fractured reservoirs is described. The non-Darcy behavior is handled in a three-dimensional, multiphase flow reservoir simulator, while the model formulation incorporates the Forchheimer equation for describing single-phase or multiphase non-Darcy flow and displacement. The non-Darcy flow through a frac...

The transport of chemicals or heat in fractured reservoirs is strongly affected by the fracture-matrix interfacial area. In a vapor-dominated geothermal reservoir, this area can be estimated by inert gas tracer tests, where gas diffusion between the fracture and matrix causes the tracer breakthrough curve (BTC) to have a long tail determined by the interfacial area. For water-saturated conditio...
