Whole cereal grain foods are rich in phytate, a Ca chelator, and could increase the risk of hip fracture. The objective of the present study was to investigate the association between baseline whole grain intake and incident hip fracture. In the present study, 29 192 women who at baseline in 1986 were aged 55-69 years, free of diabetes, and reported a plausible energy intake of 2508-20 900 kJ/d...

where δif only needs to be accounted for if the applied loads influence the virtual crack rotation, e.g. due to crack face tractions and body-type loads. Also, it is worth observing that, non-zero contributions to the variations δiK, δif occur only in those elements that experience the virtual crack rotation. The rates of the energy release rate, Hsij are obtained by differentiating Gsi in (5) ...

Fractures of the fabella are rare, with only nine cases reported in the literature. However, they can cause severe posterolateral knee pain. Other complications include osteoarthritis and, very rarely, peroneal nerve compression. All the prior cases have been transverse fractures. Here we present a first case of a sagittally oriented fabella fracture initially diagnosed on radiographs and subse...

PURPOSE To compare tibial fracture healing in rats with or without soft-tissue attachment. METHODS The left tibias of 30 Wistar rats were osteotomised and equally randomised into 3 groups. In the avascular segmental fracture group, an 8-mm bone segment were first removed and then immediately put back. In the vascular segmental fracture group, the 8-mm bone segment was not displaced, with peri...

Addition of titanium (Ti) to ASTM A710 Grade B Cu-precipitation-strengthened steel significantly increases the impact absorbed fracture energy and reduces the ductile-to-brittle transition temperature. The effect of Ti correlates with the reduction of the amount of pearlite in the ferritic microstructure. A thorough study of the mechanical properties of Ti-modified A 710B steel is presented. In...

BACKGROUND In general there is a lack of data on osteoporosis and fracture in men; this also includes low-energy distal radius fractures. The objectives of this study were to examine BMD and identify factors associated with distal radius fractures in male patients compared with controls recruited from the background population. METHODS In a 2-year period, 44 men 50 years or older were diagnos...

As a new modeling procedure of geothermal energy extraction systems, the authors present two dimensional and three dimensional modeling techniques of subsurface fracture network, based on fractal geometry. Fluid flow in fractured rock occurs primarily through a connected network of discrete fractures. The fracture network approach, therefore, seeks to model fluid flow and heat transfer through ...

BACKGROUND Recently a Fracture and Osteoporosis outpatient clinic (FO clinic) was set up at the University Medical Centre groningen (UMCG) with the aim to optimise case-finding of osteoporosis in older patients with a low-energy fracture. To provide a diagnostic setting before the start of our fo clinic, case-finding was carried out in patients who suffered an 'osteoporotic' fracture in the yea...

PURPOSE As result of the current demographic changes, osteoporosis and osteoporotic fractures are becoming an increasing social and economic burden. In this experimental study, extracorporeal shock wave therapy (ESWT), was evaluated as a treatment option for the improvement of osteoporotic fracture healing. METHODS A well-established fracture model in the metaphyseal tibia in the osteoporotic...

A concept of "Fractal Fracture Mechanics" for HDR .(Hot Dry Rock) geothermal reservoir design has been developed as an extension of conventional rock fracture mechanics. It is suggested that this concept is successfully applicable to characterize and model subsurface fracture network in HDR geothermal reservoir. Furthermore, this modeling procedure makes it possible to evaluate the thermal ener...
