Pediatric bone density and fracture
Current Osteoporosis Reports, 2007As children grow, they accumulate bone mineral, which serves as a "bone bank" for the future. Any condition that interferes with normal bone mineral accrual during childhood has the potential to reduce peak bone mass and subsequently increase future risk for fracture. In contrast to adults, for whom dual-energy x-ray absorptiometry (DXA) has become the

Fracture Analysis of Medium Density Polyethylene
2009The paper deals with the application of the reference stress method (RSM) to estimate the J and C integrals of cracked thick-walled metal as well as medium density polyethylene (MDPE) pipes. Unlike the existing solutions, the newly developed analytical approximations of the plastic limit pressure and J-integral are applicable to a wide range of crack ...

Crosslink density and fracture toughness of epoxy resins
Journal of Materials Science, 1991A series of networks of diverse crosslink density were prepared using bifunctional epoxide prepolymers of different molecular weight, crosslinked with diamine diphenyl sulphone, and their fracture behaviour investigated. The same set of resins was also modified with a reactive rubber.

Does Bone Mineral Density Affect Hip Fracture Severity?
Orthopedics, 2012The association between hip fracture and reduced bone mineral density is well documented, with reduced bone mineral density predisposing to fracture. However, it is unknown whether an association exists between the magnitude of bone density lost and the severity of the hip fracture sustained.

Bone Mineral Density and Vertebral Fractures in Men
Osteoporosis International, 1999In women, many studies indicate that the risk of vertebral fragility fractures increases as bone mineral density (BMD) declines. In contrast, few studies are available for BMD and vertebral fractures in men. It is uncertain that the strength of the relationship between BMD and fractures is similar in magnitude in middle-aged men and in postmenopausal ...

Energy-density concept in fracture mechanics
Engineering Fracture Mechanics, 1973Abstract A theory of fracture mechanics is proposed in which attention is focused on the intensity of the energy field in the crack tip region. This energy field possesses a 1/r-type of singularity for both elastic and plastic materials. The strength or amplitude of this field will be referred to as the “energy-density factor”, S.

Onset of density-driven instabilities in fractured aquifers
Physical Review E, 2018Linear stability analysis is conducted to study the onset of density-driven convection involved in solubility trapping of CO_{2} in fractured aquifers. The effect of physical properties of a fracture network on the stability of a diffusive boundary layer in a saturated fractured porous media is investigated using the dual porosity concept.

Diabetes mellitus, bone mineral density, and fracture risk
Current Opinion in Endocrinology, Diabetes & Obesity, 2007To review recent research on type 1 and 2 diabetes mellitus, bone mineral density, and fractures and to identify high-priority research areas.Recent meta-analyses and cohort studies confirm that type 1 and 2 diabetes are associated with higher fracture risk. These findings are not completely explained by lower bone mineral density in type 1 diabetes or

Assessment of fracture risk by bone density measurements
Seminars in Nuclear Medicine, 1997Bone densitometry in its various applications has become an established tool for the diagnosis of osteoporosis. Bone density has been shown to be significantly associated with the risk of future fracture in many prospective studies. From long-term prospective studies, it can be concluded that peak bone density and bone loss are important predictors of ...

Bone mineral density and fractures in Turner syndrome
The American Journal of Medicine, 2003To determine whether women with Turner syndrome who were treated with estrogen were more likely to have osteoporosis and fractures.Areal bone density at the lumbar spine and femoral neck was measured in 40 adult women with Turner syndrome and 43 age-matched healthy women using dual-energy X-ray absorptiometry.
