1. Microdialysis Sampling, Electrochemical Detection and Mass Spectrometry of Carbohydrates in Monitoring Bioprocesses
Sammanfattning : This thesis addresses; (1) the microdialysis experiment, application and methodology to maximise its performance when sampling from enzymatic bioprocesses, (2) electrochemical detection and electrochemical oxidation of carbohydrates on Au as well as Cu electrodes in alkaline solutions, and (3) coupling and maximising the performance of a microdialysis sampling based high performance anion exchange chromatography-integrated pulsed electrochemical detection-mass spectrometry system. Studies were carried out to investigate the effect of temperature, analyte as well as biomatrix complexity, analyte concentration, permeability factors, protein(enzyme)-membrane interaction and membrane material on the performance of microdialysis sampling.

2. The negotiable desert : Expert knowledge in the negotiations of the Convention to Combat Desertification
Sammanfattning : As the awareness of environmental problems increases, so too do the number of international rules and regulations to prevent them. To set up new rules, decision-makers need knowledge about the environmental issues addressed and therefore often consult experts. LÄS MER
3. Evaluation of Modern Irrigation Techniques with Brackish Water
Sammanfattning : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. LÄS MER
