  1. 26. Simulations And Experiments Of Plasma-Induced Effects In Silicon Detectors

    Författare :Ana Maria Gomez L; Ali Al-Adili; Diego Tarrío; Stephan Pomp; Andreas Solders; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; VERDI - VElocity foR Direct particle Identification; PIPS - Passive Implanted Planar Silicon; PDT - Plasma Delay Time; PHD - Pulse Height Defect; FF - Fission Fragment; ToF - Time-of-flight; MCP - Micro Channel Plat; Kärnfysik; Nuclear Physics;

    Sammanfattning : When an atomic nucleus undergoes fission, two fragments with different mass and kinetic energy are emitted. The highly unstable fission fragments (FFs) evaporate prompt neutrons soon after the nucleus splits. LÄS MER

  3. 27. Development of a Methodology for Detecting Coolant Void in Lead-cooled Fast Reactors by Means of Neutron Measurements

    Författare :Peter Wolniewicz; Håkansson Ane; Christian Jammes; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LFR; fission chamber; nuclear; reactor; leak; criticality;

    Sammanfattning : In a lead-cooled fast reactor (LFR), small bubbles (in the order of one mm or less) may enter the coolant from a leaking steam generator. If such a leakage is undetected the small bubbles may eventually coalesce into a larger bubble in local stagnation zones under the active core.

  4. 28. Acute poisoning in northern Vietnam: epidemiologic, diagnostic and therapeutic aspects

    Författare :Tran Hung Ha; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :acute poisoning;

    Sammanfattning : Poisoning is a major health problem in northern Vietnam. The aims of these studies were to improve prevention, differential diagnosis and treatment of this threat to the public. LÄS MER

  5. 29. Carbon backbone stability of Polycyclic Aromatic Hydrocarbons

    Författare :Michael Wolf; Henning Zettergren; Henrik Cederquist; Henning Schmidt; Stefano Bonetti; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : In this thesis I present results from Collision-Induced Dissociation (CID) experiments of Polycyclic Aromatic Hydrocarbons (PAHs) colliding with a stationary target gas at center-of-mass collision energies in the 20–200 eV range. In this energy region nuclear stopping processes dominate, i.e. LÄS MER

  7. 30. Rask, Resolut, Trogen : de indelta soldaterna i det svenska agrarsamhället : Västerbotten 1860-1901

    Författare :Agneta Guillemot; Kerstin Strömberg-Back; David Gaunt; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Military history; social history; infantry soldier; social recruitment of soldiers; social mobility; family structure; military education; 19th century Sweden; Indelningsverket; Sverige; Västerbotten;

    Sammanfattning : My study concerns the social recruitment of infantry soldiers in the Swedish standing army ( indelta armén). The 19th century Swedish army was composed of three parts : hired troops , the conscripts and above all the ”indelta armén”. Indelta armén was unique in the world because of its organizational form.
