Trögt för solvärme att ta marknad

Energi- och miljöintresset för alternativa energilösningar är stort. För värmeföretagen är det ett Klondyke nu när husägare vill byta ut sina oljepannor eller direktverkande el-element till mer energieffektiva lösningar. Men det går trögt för solvärme.

Rate-Boosting Using Strong Crosstalk in Next Generation Wireline Systems

Next-generation wireline systems may exploit fre- quencies up to several hundred MHz on short lines. Strong crosstalk coupling, comparable to the direct paths, is one of the main channel characteristics at high frequencies. Instead of fully cancelling all crosstalk, we utilize strong crosstalk paths to boost data-rate for active users. Two linear precoding schemes, based on maximum ratio-combining

Mira is the perfect purity where the demonic of the master mason has no access. The craftsman’s wife is the embodiment of innocence, the heavenly depiction of mankind as opposed to demonic Manole. “Serenity” and “light” are words that repeatedly occur in her monologue thus suggesting the plenitudine of being she is about to conceive when she would be raising into the light her perfect precious, th

Individual Producer Responsibility in the WEEE Directive - From Theory to Practice?

In the current discourse over what constitutes successful Extended Producer Responsibility (EPR) policy implementation, there is an on-going debate over the ability of programme design to include an appropriate incentive mechanism to stimulate producers to improve the design of their products for reduced life cycle impacts, and especially the impacts and costs from the end-of-life management. At t

Studies of cadmium, mercury and lead in man. The value of X-ray fluorescence measurements in vivo

Popular Abstract in Swedish Bestämning av koncentrationen av kadmium, kvicksilver och bly i människokroppen. Värdet av röntgenfluorescensmätningar in vivo.Two XRF methods have been used for in vivo studies of mercury, cadmium and lead. Persons with a history of long-term occupational mercury exposure had elevated mercury concentrations in their kidneys (up to 65 µg/g). The minimum detectable concentration varied between 12 and 45 µg/g. Battery plant workers had elevated cadmium concentrations in their kidneys (up to 350 µg/g) and liver (up to 80 µg/
