  1. 1. On measurement and monitoring of reactivity in subcritical reactor systems

    Författare :Carl Berglöf; Janne Wallenius; Vasily Arzhanov; Massimo Salvatores; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; reactor; ADS; accelerator-driven systems; subcriticality determination; noise techniques; pulsed neutron source; reactivity monitoring; Nuclear physics; Kärnfysik;

    Sammanfattning : Accelerator-driven systems have been proposed for incineration of transuranic elements from spent nuclear fuel. For safe operation of such facilities, a robust method for reactivity monitoring is required. Experience has shown that the performance of reactivity measurement methods in terms of accuracy and applicability is highly system dependent. LÄS MER

    Sammanfattning : Traumatic brain injury (TBI) is a major cause of death and disability. Intracranial secondary insults (e.g. intracranial haematoma, brain oedema) and systemic secondary insults (e. LÄS MER

  4. 3. Autonomic reactivity in muscle pain : clinical and experimental assessment

    Författare :Nebojsa Kalezic; Eugene Lyskov; Stein Knardahl; Umeå universitet; []

    Sammanfattning : There are numerous indications of possible involvement of the autonomic nervous system in the genesis of chronic pain. The possibility exists that sympathetic activation is related to motor dysfunction and changes in sensory processing, which have otherwise been implicated in musculoskeletal disorders. LÄS MER
