The worksite is an ideal forum for cancer risk assessment. We describe here the baseline characteristics of a large cohort. Participants completed surveys that assessed a variety of risk factors and behavioral mediators. Personalized feedback letters identified cancer risks. A total of 4395 surveys were received. Cancer prevalence was 6.5% (range, 4.3% to(More)
AIMS Physical activity (PA) has positive effects on bone accrual and geometry in children during growth. However, we do not know how PA influences adaptations in bone architecture during growth. We evaluated the contribution of PA to bone density, architecture and strength in adolescents. METHODS We used HR-pQCT (XtremeCT, Scanco Medical) to assess(More)
For wireless ad hoc networks with multihop transmissions and Rayleigh fading, this paper maximizes the overall system throughput subject to QoS constraints on power, probability of outage, and data rates. Formulations are also given which minimize delay and optimize network resources in a wireless ad hoc network, where each link is shared by multiple(More)
Ballistic performance, at effective strain rates of (10–10 s ), for polymeric dicyclopentadiene (pDCPD) was compared with two epoxy resin/diamine systems with comparable glass transition temperatures. The high rate response was characterized in terms of a projectile penetration kinetic energy, KE50, which describes the projectile kinetic energy at a(More)

Using solid state (13)C NMR data and elemental composition in a molecular mixing model, we estimated the molecular components of the organic matter in 16 recycled organic (RO) wastes representative of the major materials generated in the Sydney basin area. Close correspondence was found between the measured NMR signal intensities and those predicted by the(More)
An unusual case of calciphylaxis, presenting at the onset of end-stage renal disease and evolving into an extended and arduous hospital stay, is described. The medical approach to this case is addressed briefly, but the main focus of this paper is to describe, in the words of various participants, the events and interactions that occurred and to learn from(More)
