Identification of anaerobic ammonium oxidizing (anammox) bacteria by molecular tools aimed at the evaluation of bacterial diversity in autotrophic nitrogen removal systems is limited by the difficulty to design universal primers for theBacteria domain able to amplify the anammox 16S rRNA genes. Ametagenomic analysis (pyrosequencing) of total bacterial diversity including anammox population in f...

A laboratory-scale completely autotrophic nitrogen removal over nitrite (Canon) biofilm reactor was applied to remove nitrogen and organic carbon from swine digester liquor for 150 d. A stable nitrogen removal rate was reached after a three-week adaptation period. The nitrogen loading rate of influent were 0.20±0.04, 0.26±0.04, 0.26±0.07 kg N m(-3) d(-1) in period I, II and III, respectively. N...

The written transmission of knowledge has played a great part in the advancement of medicine, and historical documents hold the key to a full exploration of the history of medicine. Some fields, including disciplines that deal with peripheral nerve disorders, have received little benefit from such valuable material. In particular, peripheral nerve surgery lacks perspectives from historical data...

Multispectral images, including red and near-infrared bands, have proved efficient for vegetation-soil discrimination and agricultural monitoring in remote sensing applications. However, they remain little used in ground-based and unmanned aerial vehicle (UAV) imagery, due to a limited availability of adequate 2D imaging devices. A methodology is proposed to obtain simultaneously the near-infra...

The eld of nonmonotonic logic, sixteen years old now, is devoted to solve the problem of reasoning under incomplete knowledge, whose good understanding is essential to the construction of AI as a science and whose relevance reaches far beyond AI applications. During these years, many insights have been accumulated in the form of desirable properties the proposed formalisms should exhibit and of...
