1. Design for e-training
Sammanfattning : This thesis is about designing technology that supports and enhances learning in and for the workplace. This is realized through an e-training system of web lectures. Designing e-training means designing for interaction in a user friendly way while accommodating for the pedagogical and instructional strategies that are inherent in learning systems. LÄS MER
2. Influence of fibre modification on moisture sorption and the mechanical properties of paper
Sammanfattning : Fibre modification might be a way to improve the performance of paper, to increase its cost competiveness and enable new paper-based products to be developed. Therefore, the influence of fibre modification (with polyelectrolytes or by fibre cross-linking) on the mechanical properties of special importance for packaging paper grades was studied. LÄS MER
3. Demokratins stridslinjer : Carl Lindhagen och politikens omvandling, 1896–1923
Sammanfattning : Carl Lindhagen was one of Sweden’s most well-known politicians at the beginning ofthe 20th century. He entered parliament as a Liberal in 1897 but joined the Social Democrats in 1909. In 1917 he became a key figure in forming the Left Socialist party,which became the Swedish Communist Party in 1921 – although it expelled him in that moment. LÄS MER
4. Deformation and Fracture Behavior of Transparent Wood-Polymer Biocomposites
Sammanfattning : Transparent wood-polymer biocomposites (TWPBs) are interesting wood-based materials with a unique combination of optical transmittance and mechanical properties. The wood substrate is delignified (removal of lignin) while the wood microstructure is preserved. LÄS MER
5. Testing and Evaluation of Interfibre Joint Strength under Mixed-Mode Loading
Sammanfattning : The failure properties of interfibre bonds are the key for the build-up of strength in fibrous materials such as paper and paperboard. In order to tailor the properties of such materials by chemical or mechanical treatments and to learn how such modifications influence the properties at a microscopic level, direct measurement of individual fibre--fibre crosses are typically performed.
