Osteoporosis is characterized by low bone mass and micro architectural deterioration of bone tissue with a consequent increase in bone fragility and susceptibility to fractures. It is not a component of normal aging but a disease process that is both treatable and preventable. Despite this fact, osteoporosis is a problem...
Fracture represents the single most important clinical event in patients with osteoporosis, yet remains under-predicted. As few premonitory symptoms for fracture exist, it is of critical importance that physicians effectively and efficiently identify individuals at increased fracture risk. This study shows that there exists a variety of predictors of future...
This white paper study presents an analysis of trabecular bone structure in standard radiographs using Fourier transforms and principal components analysis PCA to identify contributions to hip fracture risk. Both PCA and fractal analysis of the FFT data could discriminate successfully between the fracture and control groups, although PCA was...
Anadarko Petroleum Corp. employed advanced fracture mapping technology by using new, in-well tiltmeters and fracture modeling to optimize hydraulic fracture stimulation treatments in two coalbed methane CBM plays. This article provides information on how the use of in-well tiltmeters and fracture modeling enabled the Anadarko Petroleum operator to achieve significant,...
Results of a new analysis of clinical data for osteoporosis medications, including bisphosphonates, calcitonin, estrogen therapies and SERMS selective estrogen receptor modulators showed that alendronate provided the best protection against non-vertebral fractures. The study used an indirect method to compare six current treatments. This review showed that alendronate was substantially...
In this paper, perforation response of a thin beam struck by a rigid, blunt projectile moving at a high velocity is simulated using, respectively, uniform fracture strain, Johnson-Cook's, and Bao-Wierzbicki's fracture locus for 2024-T351 aluminum alloy. The former two predict that materials in the impacted area of the beam beneath...
The Washington hydraulic fracture test was developed under the strategic highway research program to address the need for a rapid, inexpensive test for concrete aggregate freeze-thaw durability. The original test and analysis procedures were not sufficiently reliable and accurate to merit widespread adoption and implementation. Several follow-up research efforts have...
The paper mentions that understanding why and how fractures came about enables one to better predict and model their effect on fluid flow. Genetically, fractures can result from: (1) tectonic (fold- and fault-related), (2) regional joint or cleat system, (3) contractional (chicken wire, digenesis-related or columnar), and (4) surface-related or...
The paper points out that the detection of the subsurface characteristics and distribution of fractures is critical to petroleum reservoir profitability. Cost-effective data can be gathered that enables predictive models to maximize production from fractured reservoirs. It also adds that the natural fractures have influenced reservoir performance in the fine-grained...
The paper mentions that improvements in horizontal drilling of fractured oil shale plays can have a steep learning curve. Attaining a cost-effective level of success can be related to efficiency of drilling, proper orientation of the horizontal leg to intersect the maximum number of fractures, avoiding formation damage, using appropriate...
Osteoporosis is a systemic skeletal disease characterized by low bone mass, micro architectural deterioration of bone tissue, and a consequent increase in bone fragility and susceptibility to fracture. Approximately 10 million people in the United States, 80% of whom are women, have osteoporosis, and another 18 million (83% women) have...
In his most ambitious foreign policy speech to date, Barack Obama robustly defended his stance on Iraq yesterday, accusing the Bush administration of pursuing a "single-minded" foreign policy that has cost thousands of lives, tarnished America's image and emptied the nation's coffers. Ahead of a trip to Europe and the...

Ever since the Episcopal Church, the U.S. branch of the worldwide Anglican Communion, accepted an openly gay bishop in 2003, there have been rumbles of a fracture in the 77-million-member denomination over whether there is only one true way to read Scripture. But today, the Communion still stands,...
