  2. 1. Energy and intensity modulated radiation therapy with electrons

    Author : Lennart Olofsson; Mikael Karlsson; Magnus Karlsson; Björn Zackrisson; Erik Traneus; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Radiation therapy; Conformal therapy; IMRT; Electrons; Electron treatment head; Electron MLC; Bremsstrahlung reduction; Integral dose; Penumbra; Output factor; Strålningsvetenskap; Radiation biology; Strålningsbiologi; radiofysik; radiation physics;

    Abstract : In recent years intensity modulated radiation therapy with photons (xIMRT) has gained attention due to its ability to reduce the dose in the tissues close to the tumour volume. However, this technique also results in a large low dose volume. READ MORE

  4. 2. Arc Evaporated Titanium Carbonitride Coatings

    Author : Lennart Karlsson; Wolf-Dieter Münz; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : TiCxN1-x thin films is an important group of coatings for enhancing wear-resistance of, e.g., tools for metal cutting. The influence of microstructure, composition, and residual stress state, on the mechanical properties of such films, have been investigated. READ MORE

  5. 3. Dream Experience - Phenomenology meets Cognitive Neuroscience

    Author : Lennart Karlsson; Filosofiska institutionen; []
    Keywords : HUMANIORA; HUMANITIES; Philosophical logic; dream symbolism; neuroscience; delusional states; visual awareness; lucid dreaming; Phenomenology; dreaming; Teoretisk filosofi; logik;

    Abstract : This treatise examines what I call the ‘traditional view’ on the phenomenology of dreaming. According to this view, dreams are experienced in more or less the same way as waking reality – that is, our experience of “being-in-the-dream” is very much like our experience of “being-in-the-world”.

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : .... READ MORE

  7. 5. Microscopic Properties of Superdeformed Nuclei

    Author : Lennart B Karlsson; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; superdeformation; Nilsson-Strutinsky; modified oscillator potential; moments of inertia; transition energies; rotational bands; quadrupole moments; spin assignments; identical bands; additivity.; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; kvantmekanik; klassisk mekanik; thermodynamics; Matematisk och allmän teoretisk fysik; termodynamik; relativitet; statistisk fysik; Fysicumarkivet A:1999:Karlsson;

    Abstract : Many high spin rotational bands in superdeformed nuclei have been found in the A ~ 140-150 region, but so far no linking transitions to known normal-deformed states have been found in these nuclei. Therefore, configuration and spin assignments have to be based on indirect spectroscopic information. READ MORE
