Translation, cross-cultural adaptation, validation, and reliability of the University of Wisconsin running injury and recovery index to Brazilian Portuguese (UWRI-BR).

Objective: To translate and cross-culturally adapt the University of Wisconsin Running Injury and Recovery (UWRI) to Brazilian Portuguese (UWRI-BR) and assess its psychometric properties.

Methods: The Brazilian version of the UWRI questionnaire was based on the guideline proposed by Guillemin. The UWRI was translated, back-translated, and culturally adapted.

Effect of anaerobic digestion and liming on plant availability of phosphorus in iron- and aluminium-precipitated sewage sludge from primary wastewater treatment plants.

More efficient plant utilisation of the phosphorus (P) in sewage sludge is required because rock phosphate is a limited resource. To meet environmental legislation thresholds for P removal from wastewater (WW), primary treatment with iron (Fe) or aluminium (Al) coagulants is effective. There is also a growing trend for WW treatment plants (WWTPs) to be coupled to a biogas process, in order to co-generate energy.
