1. Oxygen-reducing enzymes in coatings and films for active packaging
Sammanfattning : Oxygen scavengers are used in active packages to protect the food against deteriorative oxidation processes. The aim of this work was to investigate the possibilities to produce oxygen-scavenging packaging materials based on oxygen-reducing enzymes. LÄS MER
2. Epiphytic lichen responses to nitrogen deposition
Sammanfattning : Nitrogen (N) deposition has increased globally over the last 150 years and further increase is predicted for the future. Nitrogen is an important nutrient for lichens, involved in many processes in both photobiont and mycobiont. However, N can be a stressor, causing many lichens and lichen communities to disappear with increased deposition. LÄS MER
3. Event-triggered control of multi-agent systems: pinning control, cloud coordination, and sensor coverage
Sammanfattning : A multi-agent system is composed of interconnected subsystems, or agents. In control of multi-agent systems, the aim is to obtain a coordinated behavior of the overall system through local interactions among the agents. Communication among the agents often occurs over a wireless medium with finite capacity. LÄS MER
