Availability, ease of use, relative low cost, and minimal radiation exposure have made dual-energy x-ray absorptiometry the most widely used technique worldwide to obtain bone measurements for both research and clinical purposes in pediatric populations. However, errors related to growth and maturity significantly diminish the accuracy of dual-energy x-ray absorptiometry bone measurements. Seve...

Let log ( d dx ) be the generator of the1-parameter group { d dxa |a ∈ R} of fractional order differentiations acting on the space of operators of Mikusinski ([5]). The Lie algebra glog generated by log ( d dx ) and log x is a deformation and can be regarded as the logarithm of Heisenberg Lie algebra. We show glog is isomorphic to the Lie algebra generated by d ds log(Γ(1 + s)) and d ds . Hence...

• To be aware of how malnutrition presents and how to screen, assess, and monitor patients for nutritional risk and for response to nutritional support; • To be aware of the importance of the routine screening all patients for malnutrition and of the continued monitoring of those at risk; • To appreciate the value of such diagnostic methods combined with measures of growth and development to in...

OBJECTIVE To evaluate how bone mineral density in the calcaneus measured by a dual energy X-ray laser (DXL) correlates with bone mineral density in the spine and hip in Turkish women over 40 years of age and to determine whether calcaneal dual energy X-ray laser variables are associated with clinical risk factors to the same extent as axial bone mineral density measurements obtained using dual ...

The project "Energy and Society," sponsored by the Swedish Secretariat for Futures Studies, has studied different indigenous energy sources as alternatives to imported oil in Sweden. One alternative is nuclear energy, antoer is renewable energy. Large uncertainties are associated with both alternatives today. The main characteristics of an energy policy for the rest of the century that does not...
