Femur bone mineral density, age and fracture type in 300 hip-fractured women

Aging Clinical and Experimental Research, 2002
Several studies showed that cervical and trochanteric hip fractures were associated with different levels of bone mineral density (BMD). Our aim was to investigate the association between femur BMD and hip fracture type at different ages.We studied 300 postmenopausal women affected by their first hip fracture. 17 women could not undergo BMD measurement

Fracture spatial density and the anisotropic connectivity of fracture networks

2000
The permeability of fractured rock depends on both the average transmissivity of the fractures and on how the fractures connect together to form a network. The connectedness of a network is a function of the spatial density of the fractures, which can be measured directly at the surface or inferred from the subsurface using seismic travel times ...

Fracture Density Prediction Using Elastic Parameters of Rocks in Fractured Reservoirs

Proceedings, 2007
Diffuse fracture characterization, in hydrocarbon producing reservoirs, is generally based on analysis of BHI logs. It is thus strongly dependent on quality and availability of these data. We propose a new method of diffuse fracture density estimation, which is based on relations between dynamic elastic parameters of rocks and fracture density.
