1. Oxidative spreading in polypropylene as studied by iImaging chemiluminescence
Sammanfattning : .... LÄS MER
2. New Approaches to Investigate and Prevent Oxidation of Polypropylene
Sammanfattning : When employing chemiluminescence to evaluate stabiliserperformance in a polymer, the induction time or the time toreach maximum chemiluminescence intensity is often used. Insuch an experiment the longest part of the experiment isnormally the time before the oxidation starts. LÄS MER
3. Design of Rare Earth Free Permanent Magnet Generators
Sammanfattning : Low speed permanent magnet (PM) synchronous generators (SGs) are commonly used in renewable energy. Rare earth (RE) PMs such as neodymium-iron-boron are a popular choice due to their high performance. LÄS MER
4. Rare Earth Metal–Free Permanent Magnet Generators
Sammanfattning : Permanent magnet (PM) synchronous generators (SGs) are used in renewable energy production. The preferred PM material is neodymium-iron-boron (NdFeB), which has very high performance and, until recently, low cost. LÄS MER
5. Linking plant population dynamics to the local environment and forest succession
Sammanfattning : Linking environmental variation to population dynamics is necessary to understand and predict how the environment influences species abundances and distributions. I used demographic, environmental and trait data of forest herbs to study effects of spatial variation in environmental factors on populations as well as environmental change in terms of effects of forest succession on field layer plants.
