Abstract: A method determines the time required for a timed up and go test and for verifying an ascertained result. A distance measuring device is provided which continuously measures the distance from a subject located in front of a chair to the backrest of the chair and which forwards the distance to a control unit. The chair is positioned in particular at a specified distance to a wall, an obstacle, or a marking. The measured distance values recorded by the distance measuring device are continuously recorded. The subject is instructed to stand up from the chair, walk forwards, in particular towards the wall, the obstacle, or the marking, and then turn around, in particular in front of the wall, the obstacle, or in the region of the marking, and sit back down on the chair. The subject carries out these instructions to the best of their ability.

Abstract: Integrated methanogenic anaerobic reactor and membrane bioreactor, and method for eliminating organic matter and nitrogen in urban or industrial wastewater, preferably with COD concentrations between 150 and 5000 mg/L and where the eliminations of total nitrogen that occur are between 15 and 50 mg/L, at temperatures above 15° C. The wastewater treatment takes place thanks to three stages of treatment: methanogenic anaerobic stage, anoxic stage with biofilms and suspended biomass and aerobic filtration stage with biofilms and suspended biomass.
