[1] While permeability scaling of fractured media has been so far studied independently at the fractureand networkscales, we propose a numerical analysis of the combined effect of fracture-scale heterogeneities and the network-scale topology. The analysis is based on 2 10 discrete fracture network (DFNs) simulations performed with highly robust numerical methods. Fracture local apertures are di...

Fracture healing requires two major pre-requisites; sufficient blood supply and mechanical stability [1-2]. Optimum mechanical conditions for fracture healing remain unknown, but micro-movements of the fracture fragments are significant to a developing healing callus [2-3]. This study uses Finite Element analysis to evaluate an idealized neck fracture callus, for single, and two lag screw intra...

BACKGROUND Thrombin related peptide (TP508) is a 23 amino-acid synthetic peptide that represents a portion of the receptor-binding domain of thrombin molecule. Previous studies have shown that TP508 can accelerate musculoskeletal tissue repair including fracture healing. OBJECTIVES The aim of this study was to investigate the effect of TP508 on fracture healing in a murine fracture model repr...

in the present research, damage mechanisms during room temperature uniaxial tensile testing of two different modern high strength dual phase steels,dp780 and dp980, were studied. detailed microstructural characterization of the strained and sectioned samples was performed by scanning electron microscopy (sem). the results revealed that interface decohesion, especially at the triple junctions of...

The way fractures affect seismic waves depends on fracture mechanical parameters, such as compliance and saturating fluid, and on their geometric properties, such as dimensions and spacing. When fractures are small relative to the seismic wavelength, waves will be weakly affected by fractures, and in effective medium theory, a zone comprised of many small fractures is equivalent to a homogeneou...

OBJECTIVES To review the causes and management of penile fracture and to compare between surgical and conservative management as well as immediate and delayed interventions in terms of overall and specific complications. METHODS A search of all reported literature was conducted for all articles reporting on the management and outcomes of penile fractures. Full texts of relevant articles were ...
