  1. 21. Source efficiency and high-energy neutronics in accelerator-driven systems

    Författare :Per Seltborg; Waclaw Gudowski; Enrique González-Romero; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic physics; Atomfysik;

    Sammanfattning : Transmutation of plutonium and minor actinides in accelerator-driven systems (ADS) is being envisaged for the purpose of reducing the long-term radiotoxic inventory of spent nuclear reactor fuel. For this reason, the physics of sub-critical systems are being studied in several different experimental programs across the world. LÄS MER

  3. 22. Towards better quality of life after radiation therapy by improved response modeling

    Författare :Eleftheria Alevronta; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: To improve the quality of life of radiotherapy cancer survivors we need to improve our knowledge of the dose, volume and time-response relations of radiotherapy induced late effects. Aims: The aim of the thesis was to investigate predictors for normal-tissue complications of head and neck, and gynecological radiotherapy using response modeling. LÄS MER

  4. 23. Versatile and Antique World of RNA : The Simplicity of RNA Mediated Catalysis

    Författare :Ema Kikovska; Leif Kirsebom; Venkat Gopalan; Uppsala universitet; []
    Nyckelord :Microbiology; RNA Catalysis; RNase P; Metal ions; tRNA Processing; Ribozyme; Mikrobiologi;

    Sammanfattning : RNA is the only biological molecule that can function both as a repository of information and as a catalyst. This, together with the ability to self-replicate, led to recognition of RNA as ‘prelude to life’.My work highlights some of the important features of RNA as a catalyst, exemplified by RNase P.

  5. 24. Monitoring and control of laser beam butt joint welding

    Författare :Morgan Nilsen; Anna-Karin Christiansson; Fredrik Sikström; Michael Schmidt; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser beam welding; Optical sensors; Joint tracking; Varying gap; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Laser beam welding is one important technology in automated production. It has several advantages, such as the ability to produce deep and narrow welds giving limited heat induced deformations. The laser beam welding process is however sensitive to how the high power laser is positioned with regards to the joint position. LÄS MER

  7. 25. Chloromethane Complexation by Cryptophanes : Host-Guest Chemistry Investigated by NMR and Quantum Chemical Calculations

    Författare :Zoltan Takacs; Jozef Kowalewski; Mikael Akke; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Host–guest complexes; inclusion phenomenon; cryptophanes; NMR; kinetics; activation energy; dipolar interaction; exchange; quantum chemical optimization; calculated chemical shifts; NOESY; cavity size; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Host–guest complexes are widely investigated because of their importance in many industrial applications. The investigation of their physico–chemical properties helps understanding the inclusion phenomenon. The hosts investigated in this work are cryptophane molecules possessing a hydrophobic cavity.
