    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anechoic chamber; TEM transmission cells; FDTD; circularly polarized electromagnetic fields; reduced coupling; noise matching; matching networks; low noise amplifiers; upper thoracic spine; surface coils; Nuclear magnetic resonance; magnetic resonance imaging; non-thermal biological effects; blood-brain barrier; Electronics; Elektronik;

    Sammanfattning : This thesis concerns both design and optimization of NMR imaging systems and studies on non-thermal biological effects of electromagnetic fields. These two research fields are linked together by the fact that humans are subject to static and pulsed magnetic fields as well as to magnetic radio frequency fields (RF) during an NMR imaging investigation.

  2. 2. Thermal physiology and metabolism Interplay between heat generation and energy homeostasis

    Detta är en avhandling från Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Författare :Gustavo Abreu-Vieira; Stockholms universitet.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; fysiologi;

    Sammanfattning : Mammal metabolism is intimately connected to the maintenance of body temperature. While metabolic pathways invariably produce heat as a by-product, the natural heat present in the environment also plays a role in defining the adaptive metabolism and general physiology of an organism.

    Sammanfattning : Popular Abstract in Swedish Lokal behandling med målsättning att förstöra kroppsvävnad genom uppvärmning (termoterapi) kan i vissa fall vara ett alternativ eller komplement till kirurgi. I avhandlingen presenteras utrustning och metoder för att, utifrån en fysikalisk synvinkel, göra sådana behandlingar säkrare och effektivare. LÄS MER

    Sammanfattning :  Infrared (IR) imaging devices based on energy detection has shown a dramatic development in technology along with an impressive price reduction in recent years. However, for a low-end market as in automotive applications, the present cost of IR cameras is still the main obstacle to broadening their usage. LÄS MER
