Dual-Energy X-Ray Absorptiometry: Beyond Bone Mineral Density Determination
Significant improvements in dual-energy X-ray absorptiometry (DXA) concerning quality, image resolution and image acquisition time have allowed the development of various functions. DXA can evaluate bone quality by indirect analysis of micro- and macro-architecture of the bone, which and improve the prediction of fracture risk. DXA can also detect existing fractures, such as vertebral fractures...
متن کاملUltraviolet Interstellar Linear Polarization. Iii. Features
Astro-2 has revealed a broad, weak spectral feature in the ultraviolet interstellar linear polarization for two lines of sight, conÐrming the original detection toward HD 197770 and adding HD 147933È4. These are the only two polarization features found in some 30 lines of sight now observed. Both features are centered close to 2175 the position of the ubiquitous ultraviolet extinction bump. Two...
متن کاملCoupled exposure to ingredients of cosmetic products: III. Ultraviolet filters.
BACKGROUND The use of cosmetics exposes consumers to mixtures of ingredients, many of which are potential allergens. Ultraviolet (UV) filters are used not just in sunscreens, but also in other products. Many UV filters are known contact allergens and photoallergens. OBJECTIVE To examine the pattern of co-exposure to UV filters in cosmetics. METHODS A survey of products marketed in Germany, ...
متن کاملPolarization of III-nitride blue and ultraviolet light-emitting diodes
Polarization-resolved electroluminescence studies of III-nitride blue and ultraviolet sUVd light-emitting diodes sLEDsd were performed. The LEDs were fabricated on nitride materials grown by metalorganic chemical vapor deposition on sapphire substrates s0001d. Transverse electric sTEd polarization dominates in the InGaN/GaN quantum-well sQWd blue LEDs sl8=458 nmd, whereas transverse magnetic sT...
