  2. 6. Low-Dose Ionizing Radiation Induces Neurotoxicity in the Neonate : Acute or fractionated doses and interaction with xenobiotics in mice

    Author : Sonja Buratovic; Per Eriksson; Henrik Viberg; Bo Stenerlöw; Anders Fredriksson; Jean-René Jourdain; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionizing radiation; Neonatal; Neurotoxicity; Behaviour; Nicotine; Ketamine; Mouse; Cognition; Acute irradiation; Fractionated irradiation;

    Abstract : This thesis examines the developmental neurotoxic effects of exposure to low-dose ionizing radiation (IR), alone or together with xenobiotics, during a critical period of neonatal brain development in mice.During mammalian brain development there is a period called the brain growth spurt (BGS), which involves extensive growth and maturation of the brain.

  4. 7. Optical Properties of Nanoparticles in Composite Materials

    Author : Lin Dong; Sergei Popov; Ari Friberg; Toralf Scharf; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Nanoparticles are synthetic structures with dimension from 1 to 100 nanometers and are various in types. Some favorable properties peculiar to the nanoparticles (generally owing to size effects) make them prevailing and beneficial for applications in different scientific and engineering fields.

  5. 8. Voltage Losses in Non-fullerene Organic Solar Cells

    Author : Yuming Wang; Feng Gao; Fengling Zhang; René Janssen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Non-fullerene acceptors have significantly boosted the efficiencies of organic solar cells (OSCs) in the past few years. State-of-the-art OSCs have achieved a certificated power conversion efficiency of 17.4%. READ MORE

  6. 9. Helical tomotherapy for total marrow and total skin irradiation : Optimisation, verification, and clinical results

    Author : André Änghede Haraldsson; Lund Medicinsk strålningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALL; Leukemia; radiotherapy; hematology; Oncology; Leukemia; radiotherapy; Tomotherapy; Oncology; ALL;

    Abstract : In modern cancer therapy, radiotherapy (RT) is a vital part of most treatments. Most RT treatments in Sweden are performed using intensity-modulated radiotherapy (IMRT) with fixed or dynamic arc delivery. The dose gradients outside the target are steep, the margins are small, and the treatment delivery is complicated. READ MORE

  7. 10. Haptic and visual simulation of material cutting process : a study focused on bone surgery and the use of simulators for education and training

    Author : Magnus G. Eriksson; Jan Wikander; Ingela Nyström; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; surgical simulation; virtual reality; haptic feedback; surgical training; medical simulators; metrics; 3D visualization; Medical technology; Medicinsk teknik;

    Abstract : A prototype of a haptic and virtual reality simulator has been developed for simulation of the bone milling and material removal process occurring in several operations, e.g. temporal bone surgery or dental milling. The milling phase of an operation is difficult, safety critical and very time consuming. READ MORE
