11. Extent and limitations of functional redundancy among bacterial communities towards dissolved organic matter
Sammanfattning : One of the key processes in the carbon cycle on our planet is the degradation of dissolved organic matter (DOM) in aquatic environments. The use of organic matter by bacteria links energy from DOM to higher trophic levels of the ecosystem when bacteria are consumed by other organisms. This is referred to as the microbial loop. LÄS MER
12. Making a difference : project result improvement in organizations
Sammanfattning : This thesis is about how project results can be improved in organizations. The focus is on project-intensive organizations, where a central part of the operative work is carried out in project form. This is common in product development, software development, business development, industrial construction, etc. LÄS MER
13. Olfaction in the spruce bark beetle, Ips typographus : receptor, neuron and habitat
Sammanfattning : The bark beetle Ips typographus regularly kills spruce trees in the Palearctic. Spruces are colonized by means of attraction to an aggregation pheromone. Attraction is modulated by anti-attractive volatiles (NHV) from non-host plants. In this thesis, olfaction in I. LÄS MER
14. Process analytical methods for monitoring of the film coating on pharmaceutical pellets and tablets using NIR spectrometry and image analysis
Sammanfattning : Pharmaceutical tablets and pellets are often covered with a coating. There is a need for methods that enable monitoring of the growth of such films during processing. Such analyses can be performed using process analytical chemical methods based on near infrared (NIR) diffuse reflectance spectrometry. It provides with analyses that take only ca. LÄS MER
15. SOFC Modeling Considering Mass and Heat Transfer, Fluid Flow with Internal Reforming Reactions
Sammanfattning : Fuel cells are promising for future energy systems, since they are energy efficient and, when hydrogen is used as fuel, there are no emissions of greenhouse gases. Fuel cells have during recent years various improvements, however the technology is still in the early phases of development. LÄS MER
