  2. 1. Integration of MRI into the radiotherapy workflow

    Author : Joakim Jonsson; Tufve Nyholm; Mikael Karlsson; Magnus Karlsson; Uulke van der Heide; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; magnetic resonance imaging; radiotherapy; treatment planning; image registration; workflow; radiofysik; radiation physics;

    Abstract : The modern day radiotherapy treatments are almost exclusively based on computed tomography (CT) images. The CT images are acquired using x-rays, and therefore reflect the radiation interaction properties of the material. READ MORE

  4. 2. Computational exploration of cancer genomes

    Author : Joakim Karlsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cancer genomics; Transcriptomics; Driver genes; Copy number changes; Immunogenomics; Cancer of unknown primary; Uveal melanoma;

    Abstract : Cancer evolves due to changes in DNA that give a cell an advantage at the expense of the remaining organism. These alterations range from individual base substitutions to broad losses or duplications of chromosomal material. READ MORE

  5. 3. Windows : Optical Performance and Energy Efficiency

    Author : Joakim Karlsson; A. Maccari; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : This thesis treats angle-resolved optical properties and the energy efficiency of windows. A theoretical evaluation of optical and thermal properties of windows is briefly surveyed and the energy performance of a large selection of windows, under different conditions, is examined. In particular, angle dependent optical properties are analysed. READ MORE

  6. 4. Optimization of Electron Beam Melting for Production of Small Components in Biocompatible Titanium Grades

    Author : Joakim Karlsson; Håkan Prof.; Mikael Bäckström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; 3D-printing; Electron Beam Melting; Titanium alloys; Chemical properties; Mechanical properties; Surface properties; Additiv tillverkning; 3D-skrivare; Electron Beam Melting; Titan; Kemiska egenskaper; Mekaniska egenskaper; Ytegenskaper; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Additive manufacturing (AM), also called 3D-printing, are technologies where parts are formed from the bottom up by adding material layer-by-layer on top of each other. Electron Beam Melting (EBM) is an AM technique capable of manufacturing fully solid metallic parts, using a high-intensity electron beam to melt powder particles in layers to form finished components.

  7. 5. Purification, Stereoisomeric Analysis and Quantification of Biologically Active Compounds in Extracts from Pine Sawflies, African Butterflies and Orchid Bees

    Author : Joakim Bång; Erik Hedenström; Kristina Sjödin; Hans-Erik Högberg; Anna-Karin Borg-Karlsson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semiochemicals; sex pheromone; pine sawflies; Bicyclus; Euglossa; chiral separation; derivatisation; GC-­MS; Organic chemistry; Organisk kemi;

    Abstract : Stereochemistry plays an important role in nature because biologically important molecules such as amino acids, nucleotides and sugars, only exist in enantiomerically pure forms. Semiochemicals carry messages, between the same species (pheromones) and between different species (allelochemicals). READ MORE
