We investigate a new numerical approach for the computation of the threedimensional flow in a discrete fracture network that does not require a conforming discretization of partial differential equations on complex three-dimensional systems of planar fractures. The discretization within each fracture is performed independently of the discretization of the other fractures and of their intersecti...

Theoretical investigations of damage and fracture of materials which are based on the concepts of the theory of complex systems are reviewed and analyzed. The models of fracture, which have been developed with the use of the methods of following theories, are considered: theory of phase transitions and statistical physics, percolation and fractals theories, theories of dynamical systems, bifurc...

 Preparing to manage weapons of mass destruction events challenges emergency services systems neighboring Syria every day. Understanding injury from explosives is essential for all providers of emergency care in both civilian and military settings. In this case, the authors present a 22-year-old man who was admitted to the emergency department with displaced skull fracture, epidural hemorrhage ...

A 72-hour aquifer test was conducted to investigate the yield and interconnectivity of deep fracture systems in the City of Conyers, Rockdale County, Georgia. Wells tapping the deep fracture systems in the underlying igneous and metamorphic crystalline rock have yields ranging from 100 to 350 gallons per minute and can be pumped on a continuous basis. During the test, drawdown in excess of 30 f...

This study aims to evaluate the biomechanical mechanism of fixation systems in the most frequent T-shaped acetabular fracture using finite element method. The treatment of acetabular fractures was based on extensive clinical experience. Three commonly accepted rigid fixation methods (double column reconstruction plates (P × 2), anterior column plate combined with posterior column screws (P + PS...

BACKGROUND Fracture-healing depends on interfragmentary motion. For improved osteosynthesis and fracture-healing, the micromotion between fracture fragments is undergoing intensive research. The detection of 3D micromotions at the fracture gap still presents a challenge for conventional tactile measurement systems. Optical measurement systems may be easier to use than conventional systems, but,...
