A 2D, hexagonal in geometry, statistical model of fracture is proposed. The model is based on the drying fracture process of the bamboo Guadua angustifolia. A network of flexible cells are joined by brittle junctures of fixed Young moduli that break at a certain thresholds in tensile force. The system is solved by means of the Finite Element Method (FEM). The distribution of avalanche breakings...

The enhanced geothermal system (EGS) is the key to improving heat production efficiency of hot dry rock (HDR). Due existence EGS, reservoir produces significant heterogeneity, so optimal design well location and injection rate has an important influence on recovery effect EGS. To solve this problem, a calculation model for output EGS under multifield coupling established in paper, different sca...

The aim of the present study was to screen potential key genes associated with osteoporotic fracture healing. The microarray data from the Gene Expression Omnibus database accession number GSE51686, were downloaded and used to identify differentially expressed genes (DEGs) in fracture callus tissue samples obtained from the femora of type I collagen (Col1a1)‑kringle containing transmembrane pro...

We present an extensive experimental study of mode-I, steady, slow crack dynamics in gelatin gels. Taking advantage of the sensitivity of the elastic stiffness to gel composition and history we confirm and extend the model for fracture of physical hydrogels which we proposed in a previous paper (Nature Mater. 5, 552 (2006)), which attributes decohesion to the viscoplastic pull-out of the networ...

Apical tight junctional formation of the rabbit corneal endothelium was examined by freeze-fracture analysis and measurement of paracellular permeability to 5(6)-carboxyfluorescein. Freeze-fracture analysis indicated that apical tight junction formation of the rabbit corneal endothelium is a dynamic process. At birth, there are few tight junctional strands present and a minimal barrier for para...

Introduction: Unstable ankle fractures are a common presentation and operative intervention has proven to improve patient outcomes. Each stage of patient management can have an impact on patient length of stay and clinical outcome. The aim of the present study is to assess how we manage the patient at each stage from their presentation right through to discharge, and if/how variation in practic...

The Habanero 1 and 3 doublet is the major component in the original electricity generation plan for the Geodynamics geothermal project in the Cooper Basin of South Australia. Various heat extraction studies have been conducted using simplified models such as a single fracture connecting the two wells or an equivalent porous medium representing the reservoir. In our approach, a more realistic fr...

Detailed numerical flow and radionuclide simulations are used to predict the flux of radionuclides from three underground nuclear tests located in the Climax granite stock on the Nevada Test Site. The numerical modeling approach consists of both a regional-scale and local-scale flow model. The regional-scale model incorporates conceptual model uncertainty through the inclusion of five models of...
