2. 1. Colloidal/Solid Phase Extraction (C/S PE) Methods Based on Hydrogel Nanoparticles, Titanium dioxide microparticles and Empore Membranes Applied to Biological and Environmental Matrices

   Author : Davide Tamburro; Leopold Ilag; Robin Couch; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomarkers; nanogels; solid-phase extraction; organophosphate esters; peptides; mass spectrometry; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Abstract : The aim of the work described in this thesis was to create and develop novel technologies in order to overcome barriers and hurdles that analytical chemistry faces focusing on sample extraction. In paper I dye containing amine groups (e.g. READ MORE

4. 2. Surface guided radiotherapy

   Author : Malin Kügele; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface guided radiotherapy; DIBH; SGRT; radiotherapy; patient positioning; intra-fraction motion; surface imaging; treatment planning; SGRT; surface guided radiotherapy; intra-fraction motion; DIBH; patient positioning; treatment planning; surface imaging;

   Abstract : Modern radiotherapy aims to treat the decease while minimizing the radiation dose to the adjacent normal tissue, to minimize acute and late effects of the treatment. The foremost technological approaches have been intensity modulated radiotherapy (IMRT) and intensity modulated proton therapy (IMPT) in combination with image guided radiotherapy (IGRT). READ MORE

5. 3. Verification of high energy photon therapy based on PET/CT imaging of photonuclear reactions

   Author : Sara Janek Strååt; Anders Brahme; Cathrine Jonsson; Iuliana Dasu; Sibylle Ziegler; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photonuclear reactions; PET CT treatment verification; High-energy photon therapy; Medical Radiation Physics; medicinsk strålningsfysik;

   Abstract : For classical and intensity modulated radiation therapy of deep-seated tumors, high-energy photons are the optimal radiation modality from an integral dose point of view. By using narrow scanned beams the treatment outcome can be improved substantially by delivering biologically optimized intensity modulated distributions often with sharp dose gradients. READ MORE

6. 4. Alain Robbe-Grillet. Les Sables mouvants du texte

   Author : Véronique Simon; Karlstads universitet; []
   Keywords : HUMANIORA; HUMANITIES; Franska; French;

   Abstract : Alain Robbe-Grillet is often regarded as the leader of the French New Novel, a 20th century literary movement breaking with literary realism. A former scientist, Robbe-Grillet invents a new Real, where imagination, memories, fantasies and dreams are given a power somehow superior to that of tangible reality. READ MORE

7. 5. Dewatering aspects at the forming section of the paper machine : Rewetting and forming fabric structure

   Author : Björn Sjöstrand; Lars Nilsson; Christophe Barbier; David McDonald; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rewetting; forming fabric; forming section; dewatering; web dryness; high vacuum suction box; vacuum dewatering; forming fabric design; numerical model; Chemical Engineering; Kemiteknik;

   Abstract : The underlying motives of the research undertaken here are twofold: to obtain a deeper understanding of the dewatering mechanisms at the forming section of a papermaking machine and to develop numerical models that describe the flow through forming fabrics. More comprehensive knowledge of dewatering in the forming section allows suggestions to be made for improvements that reduce the amount of energy used in the process without affecting the quality of the end product.
