1. 1. Behavior and cytogenesis following irradiation or isoflurane exposure to the developing brain

   Författare :Niklas Karlsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiotherapy; isoflurane; anesthesia; hippocampus; neurogenesis; memory; learning; intellicage; dentate gyrus; trace fear conditioning; open field; object recognition;

   Sammanfattning : In this thesis, the effects of an anesthetic agent, isoflurane, on the young brain and resulting behavioral effects were investigated. Anesthesia is commonly used in young children during surgery or other procedures associated with pain or discomfort. LÄS MER

3. 2. HIV and hepatitis C prevention among people who inject drugs in Sweden : harm reduction policies, risk behaviour interventions and outcomes

   Författare :Niklas Karlsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : People who inject drugs (PWID) is a heterogeneous and hard-to-reach group due to legal implications, stigma and discrimination. PWID are vulnerable to various poor health outcomes including HIV and hepatitis due to ongoing injection and sexual risk behaviours, various forms of abuse, poor health seeking behaviours, and limited access to- and retention in prevention and care programs.

4. 3. Parametric model for astrophysical proton-proton interactions

   Författare :Niklas Karlsson; Per Carlsson; Johan Rathsman; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : Observations of gamma-rays have been made from objects such as active galaxies and supernova remnants and also as diffuse emission from the Galactic ridge. The study of gamma-rays can provide information about production mechanisms and tell us about cosmic ray acceleration. LÄS MER

5. 4. Doing well by doing good : The business model innovation process for sustainability in farm-based biogas production

   Författare :Niklas Karlsson; Fawzi Halila; Maya Hoveskog; Marie Mattsson; Lára Jóhannsdóttir; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Business model innovation; Sustainable value creation; Stakeholders; Biogas production; Farmers;

   Sammanfattning : Research on innovation that leads to change and adaptation in dynamic business environments has increased rapidly in recent decades. This doctoral thesis, which focuses on business model innovation (BMI), contributes to that research with its examination of how businesses can alter their structures to create, deliver, and capture greater economic value as well as environmental and social value.

7. 5. Parametric Model for Astrophysical Proton-Proton Interactions and Applications

   Författare :Niklas Karlsson; Per Carlson; Simon Swordy; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; astrophysics; gamma rays; proton-proton interactions; cosmic rays; Astronomy and astrophysics; Astronomi och astrofysik;

   Sammanfattning : Observations of gamma-rays have been made from celestial sources such as active galaxies, gamma-ray bursts and supernova remnants as well as the Galactic ridge. The study of gamma rays can provide information about production mechanisms and cosmic-ray acceleration. LÄS MER
