39 The two concepts were, however, conflated in the wording of the General Practice Patient Survey: "Did you have confidence and trust in the doctor you saw?" We were therefore unable to distinguish between confidence and trust in our investigation.
The DD concept is however not ideal as the absence of a reduction ratio, means that dynamic coupling and joint interaction become important at the motor shaft.
This positive evaluation of the microjets concept is, however, mitigated by the far less favorable results of simulations in flight conditions, which were never studied experimentally.
Energy-efficient houses have been designed and constructed widely in cold regions, the concept is however still under experimentation in extreme hot and arid climates such as in the Gulf Cooperation Council (GCC) region where the priority is to reduce space cooling load.
The concept is however relatively new in the paediatric field.
The concept is, however, closely related to humanistic psychology and the person-centred therapy originally developed by Carl Rogers in the 1940-ies[ 16].
This concept is, however, problematic in practical application because: value must be measurable (objective, interpersonally comparable and it should be possible to aggregate it as social benefits), value must reflect different perspectives and the conflict between individual and social value has to be solved.
This concept was, however, put in doubt with the observation that a quintuple mutant of TASK-2 neutralising all amino acids in the purported sensor maintained pHo-sensitivity [22].
The concept was, however, different, aiming at describing the average probability of ACR20/50/70 response in the population rather than an accurate description of an individual's evolution of the response with time.
However, this concept is still discussed from different perspectives.
