1. Extended impregnation kraft cooking of softwood : Effects on reject, yield, pulping uniformity, and physical properties
Sammanfattning : Converting wood into paper is a complex process involving many different stages, one of which is pulping. Pulping involves liberating the wood fibres from each other, which can be done either chemically or mechanically. LÄS MER
2. Effects of Reject Refining at High Temperature on TMP Fibre Properties
Sammanfattning : .... LÄS MER
3. Risk of nitrous oxide emissions and potential of bioaugmentation when treating digester supernatant via nitrification-denitrification
Sammanfattning : This thesis examines two different impacts of sidestream treatment of digester supernatant via nitrification-denitrification in a sequenced batch reactor (SBR). One of the impacts is the detrimental formation of nitrous oxide, and the other is the positive boosting of nitrifiers to the mainstream process through bioaugmentation. LÄS MER
4. Start-up and operational strategies for deammonification plants : - a study with one-stage moving bed biofilm reactors treating reject water
Sammanfattning : To limit eutrophication, wastewater treatment plants use biological methods to convert degraded nitrogen to nitrogen gas. Deammonification, or partial nitritation in combination with anammox, has been shown to be an energy efficient process. LÄS MER
5. 60 GHz Mixer and Multifunctional MMICs in GaAs pHEMT and mHEMT technologies
Sammanfattning : In recent years, the 60 GHz band has gained increased academic and commercial interest mainly due to the relative large amount of license free and little used frequency spectrum located in vicinity of 60 GHz. The exact locations of these free frequency bands varies locally but the 5962 GHz band overlap around the world and is therefore a true world wide license free band. LÄS MER
