1. Cycle paths’ degradation processes and surface condition assessment
Sammanfattning : A shift in modal share from car driving to cycling has many benefits, both from individual- and societal perspectives, e.g., better health from an increase in physical activity, lower levels of pollution and congestion. However, there are also some potential problems with such a shift. LÄS MER
2. Improved high velocity cold copaction processing : polymer powder to high performance parts
Sammanfattning : A uniaxial High-Velocity Compaction (HVC) process for polymer powder using a cylindrical, hardened steel die and a new technique with relaxation assist was tested with a focus on the compactibility characteristics and surface morphology of the compacted materials using various heights of relaxation assist device with different compacting profiles. Relaxation assist device was presented as a new technique to reduce springback, pull-out phenomenon and to improve the compaction process. LÄS MER
3. Source, mobility and fate of critical Be, Bi, F and W from historical sulfidic-oxidic skarn tailings : Re-mining as remediation method?
Sammanfattning : There is a potential risk that geochemical cycles of several critical metals will be affected in the pristine environment, when mining of these metals increases to meet the demand in green technology. The identification of critical metals is based on the economic importance and vulnerability to supply restrictions. LÄS MER
4. Development of thermoplastic biocomposites based on aligned hybrid yarns for fast composite manufacturing
Sammanfattning : The interest in natural fibres as reinforcement for composite materials has been steadily increasing due to their attractive mechanical properties and the possibility of making more eco-friendly materials. Currently, various alternatives are being introduced for commercial applications, as fibres such as hemp, jute and flax exhibit properties, which make them appropriate for structural composite components.

5. Processes governing the drinking water microbiome
Sammanfattning : AbstractSafe drinking water is far from sterile and can contain 10^3-10^5 bacteria/mL. This water microbiome can be altered through various treatment processes in the drinking water treatment plant (DWTP), particularity when it comes in contact with biofilms. LÄS MER
