Discriminating and continuous measurement of photosynthesis and respiration by monitoring 13CO2 and 12CO2 as tracers.
The simultaneous and discriminative measurement of the photosynthesis and the respiration of the plant was attained by simultaneous monitoring of 13CO2 and 12CO2 by artificial control of 13CO2Expand
Kashiwazaki Data Quality Control and Improvement of Indirect Human Calorimeter by System Dynamics Approach
Using a system dynamics approach, a simulation model for data quality control and improvement of human calorimeter using the indirect calorimetry (IHC: indirect human calorimeter) was constructed.Expand
Development of photosynthesis and respiration measurement system using mass spectrometry.
A closed gas-exchange system was developed to measure gross photosynthesis and respiration discriminately and simultaneously. The system developed in this study included a high performance massExpand
Measurement Method of Carbohydrate Metabolism during Prolonged Exercise by Monitoring 13CO2 as Tracer.
The discriminative measurement method of the dynamic metabolic change of an administered glucose and a pre-reserved carbohydrate is clearly demonstrated during the prolonged exercise (75 W bicycleExpand
