  1. 11. Utilisation of hardwood in cross-laminated timber - A numerical study on vibrations in floors

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Johannes Jonasson; Olle Karlsson; [2022]
    Keywords : hardwood; birch; beech; clt; cross-laminated timber; vibrations; floors; footfall; accelerations; Technology and Engineering;

    Abstract : Cross-laminated timber (CLT) is an engineered wood product consisting of several layers of laminations bonded together with adhesives. In contrast to heavier construction materials, timber and other lightweight building materials are more prone to serviceability issues due to vibrations. READ MORE

  3. 12. Reactivity increasement of prehydrolysis kraft pulp from Acacia crassicarpa and Eucalyptus hybrids

    University essay from KTH/Träkemi och massateknologi

    Author : Edward Tandy; [2022]
    Keywords : Acacia crassicarpa; Eucalyptus hybrids; Pentosan removal; Pulp yield; Prehydrolysis kraft pulp; Reactivity; Acacia crassicarpa; Eucalyptushybrider; Förhydrolyserad kraftmassa; Massautbyte; Pentosan; Reaktivitet;

    Abstract : Syftet med detta examensarbete var att öka reaktiviteten hos förhydrolyserad kraftmassa genom att använda tidigare förhydrolysat och svavelsyra under förhydrolysen. Först bestämdes den kemiska sammansättningen av två olika vedråvaror (Acacia crassicarpa och Eucalyptushybrider) för att observera och korrelera med förhydrolysprocessen. READ MORE

  4. 13. Load-bearing wood connections using birch plywood : An experimental study of birch plywood gusset plates behaviour with mechanical connectors

    University essay from KTH/Byggnadsmaterial

    Author : Mattia Debertolis; Agne Laurinaviciute; [2022]
    Keywords : ;

    Abstract : A growing sustainability concern is pushing the construction industry to seekalternative materials with lower environmental impact. In the last decade useof wood as load-bearing construction has become a common trend, however,connections of timber elements are still performed by the use of steel plates. READ MORE

  5. 14. Counteracting Ammonia Inhibition in Anaerobic Digestion using Wood Residues : Evaluating Ammonium Adsorption Capacity of Fibres from Pulp and Paper Mills

    University essay from Linköpings universitet/Tema Miljöförändring; Linköpings universitet/Biogas Research Center

    Author : Marcus Wrangbert; [2021]
    Keywords : Anaerobic digestion; Ammonia inhibition; Fibres; Biogas;

    Abstract : One of the main interests in commercial methane production is to maximize the gas yield, and it is thus appealing to use material with relative high methane potential. However, such material often results in process instability whereas ammonia inhibition is common. READ MORE

  6. 15. Investigating the process parameters that influence the z-strength of liquid paperboard using data mining and machine learning

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Gustav Thaung Tolförs; [2021]
    Keywords : paperboard; liquid paperboard; z-strength; process parameters; machine learning; data mining;

    Abstract : Parameters affecting the z-strength of liquid paperboard (LPB) has been analyzed and identifiedusing data mining and machine learning on 6 years of operational data from a multi-ply LPB mill, and control and stabilizing of them was proposed. Linear regression models were built for 9 articles with satisfactory results, and whose attributes were further analyzed as the most important parameters for the z-strength. READ MORE
