  2. 1. Precipitating Amine Absorption Systems for Carbon Capture

    Author : Hanna Karlsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; Non-aqueous; AMP; Solubility; Heat of absorption;

    Abstract : Carbon capture using amine-based absorption is an established technology for the separation of gaseous CO2. It is used in the upgrading of gaseous fuels, and it has also been suggested that it could play a crucial role in the mitigation of climate change through post-combustion carbon capture and sequestration (CCS), and by creating carbon sinks through bioenergy CCS.

  4. 2. Particularly harmful particles? A study of airborne particles with a focus on genotoxicity and oxidative stress

    Author : Hanna Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : particulate matter; particles; genotoxicity; oxidative stress; DNA damage; inflammation; subway; tire-road; wood;

    Abstract : Today it is well established that particulate matter (PM) cause a wide range of health effects. The underlying mechanisms likely include inflammation, oxidative stress and genotoxicity. There is however a lack of knowledge regarding how particles from different sources contribute to these effects. READ MORE

  5. 3. From social drinking to alcohol addiction : Decision making and its neural substrates along a spectrum from social drinking to alcohol addiction

    Author : Hanna Karlsson; Irene Perini; Markus Heilig; Bo Söderpalm; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alcohol; heavy drinking; alcohol addiction; decision making; alcohol choice; fMRI; rTMS;

    Abstract : For a minority of alcohol users, the initial sip of alcohol marks the start of a life-threatening process. This thesis studies cognitive mechanisms pertinent to alcohol addiction and its development, using a spectrum of individuals that range from healthy social drinkers, through people with hazardous use, to those suffering from alcohol addiction.

  6. 4. Some aspects on strength properties in paper composed of different pulps

    Author : Hanna Karlsson; Luciano Beghello; Lars Nilsson; Lennart Stolpe; Øyvind Gregersen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper strength; reinforcement; multilayer; stratified; handsheet former; abaca; southern pine; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Abstract : For papermakers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are desirable both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging and light-weight building material. READ MORE

  7. 5. Strength Properties of Paper produced from Softwood Kraft Pulp : Pulp Mixture, Reinforcement and Sheet Stratification

    Author : Hanna Karlsson; Luciano Beghello; Lars Nilsson; Lennart Stolpe; Öyvind Gregersen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper strength; tensile strength; tearing resistance; folding endurance; fracture toughness; handsheet former; stratify; multilayer; multiply; reinforcement; refining; beating; abaca; glass fibre; polyester; lyocell; softwood; bond strength; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

    Abstract : For paper producers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are important operators both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging, furniture and light-weight building material.
