The strengths of the instruments that were developed are that a scientifically demanding quality measurement was conducted (e. g., combination of indirect and direct measurement of change, several methodological approaches to measuring results, wide range of endpoints analysed, homogeneous comparison groups, elaborate risk adjustment process). There are limitations, especially with respect to the rather great effort needed and not particularly high power for the comparison of centres. The German pension fund and the statutory health insurers are now discussing on the basis of the results of the project the routine implementation of quality assurance in children/adolescent rehabilitation and concrete steps that can be taken to implement it in routine health care.

Current practice of goal setting in inpatient rehabilitation of patients with the diagnoses named above is altogether on a relatively advanced level in the rehabilitation centres taking part in the study. The study identifies potential for development concerning a comprehensive implementation of goal setting, the realisation of patient participation, goal documentation and their integration into rehabilitation. Moreover, deeper involvement of the rehabilitation team and a stronger conceptual integration of the subject within the centres seem desirable. This can be taken up within the scope of interventions.

The utilization of a wire-mesh sensor for the measurement of chemical species conversion during the chemical adsorption of carbon dioxide in sodium hydroxide solution is reported for the first time. The wire-mesh sensor obtains cross-sectional images of the liquid-phase conductivity, which changes with the consumption of hydroxide during the reaction. A theoretical model was applied to verify the use of conductivity as an indicator for the reaction progress. Experiments were carried out using a lab-scale bubble column reactor with two wiremesh sensors at different reactor heights. The results obtained from the reactor model and experiments showed very good agreement and demonstrate the potential of this imaging instrument to follow the course of a chemical reaction via ionic species concentration even in a dense bubbly flow. This way, a better understanding of the coupling of hydrodynamics, mass transfer, and reaction in bubble columns and other reaction devices can be achieved.
