An estimated 17 million tonnes of tires are discarded annually. Re-use is achieved by retreading (9%), recycling (39%), energy recovery (37%) and landfill (5%). A preferred, but complex way of recycling is to make new tires from discarded tire rubber. Vulcanised car tire rubber has to be devulcanized …

Stricter environmental policies, increased energy prices and depletion of resources are forcing industries to look for bio-based and low carbon footprint products. For industries, flax is interesting resource since it is light, strong, environmental friendly and renewable. From flax plant to fiber products …

In the life of flowering plants, seed germination is a critical step to ensure survival into the next generation. Generally the seed prior to germination has been in a dormant state with a low rate of metabolism. In the transition from a dormant seed to a germinating seed, various epigenetic mechanisms …

The aim for this thesis is to set up and develop electroplating technique for depositing gold layers. This gold layer will be used as an thermalisation layer in a cryogenically cooled X-ray detector. Key material parameter for the gold layer is a low thermal resistivity at cryogenic temperatures. Since …

The purpose of this report is to assess the relevance of the measurement of the spectrally resolved distribution of radiation in tokamak boundary plasmas. This assessment is important and urgent in view of the recent ambition to design and construct a multi-camera configuration for hyper imaging spectroscopy1 …

Thermal comfort is determined by the combined effect of the six thermal comfort parameters: temperature, air moisture content, thermal radiation, air relative velocity, personal activity and clothing level as formulated by Fanger through his double heat balance equations. In conventional air conditioning …

Fish have the natural behaviour to move across various aquatic ecosystems and for some species this is of vital importance. Migration is often a seasonal phenomenon which occurs in order to move between habitats, such as winter refuges-, foraging- and spawning or nursery habitats, also escaping unfavourable …

With the increase of offshore activities in the Arctic, the question arises if currently existing oil spill response plans involve effective methods for removing oil slicks in Arctic conditions. The dispersant Corexit9500 is commonly applied as response agent to disperse oil slicks. It has been applied …

The aim of this applied research is to design a sustainable industrial scale enzyme based flax retting process. A systematic approach has been adopted. The screening and selection of enzymes for flax retting has been carried out. Alkaline pectinase has been identified as the most appropriate enzyme for …

Consumers expect product availability as well as product quality and safety in retail outlets. When designing or re-designing fruit and vegetables supply chain networks one has to take these demands into consideration next to traditional efficiency and responsiveness requirements. In food science literature, …
