  1. 6. Mechanisms of excitability in the central and peripheral nervous systems : Implications for epilepsy and chronic pain

    Författare :Jenny Tigerholm; Erik Fransén; Dieter Jaeger; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dendritic excitability; synchronized synaptic input; multicompartment model; epilepsy; axonal excitability; silent C–fibres; Hodgkin–Huxley dynamics; conduction velocity; KA;

    Sammanfattning : The work in this thesis concerns mechanisms of excitability of neurons. Specifically, it deals with how neurons respond to input, and how their response is controlled by ion channels and other active components of the neuron. LÄS MER

  4. 8. Systemic effects of occupational exposure to arsenic : with special reference to peripheral circulation and nerve function

    Författare :Birgitta Json Lagerkvist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arsenic toxicity; Cold-induced vasospasm; Finger systolic pressure; Nerve conduction velocity; Occupational exposure; Raynaud s phenomenon; Serotonin antagonist;

    Sammanfattning : Smelter workers who were exposed to air-borne arsenic for a mean of 23 years, and age-matched referents, were examined with clinical, physiological, and neurophysiological methods. Exposure to arsenic in workroom air was estimated to have been around the Swedish occupational limits, which were 500 yg/m before 1975 and 50 yg/ra thereafter. LÄS MER

  5. 9. Experimental Studies of Charge Transport in Single Crystal Diamond Devices

    Författare :Saman Majdi; Jan Isberg; Ricardo S. Sussmann; Uppsala universitet; []
    Nyckelord :Single crystal diamond; carrier transport; CVD diamond; time-of-flight; mobility; IR detector; compensation; diamond diode; drift velocity; thermal detector;

    Sammanfattning : Diamond is a promising material for high-power, high-frequency and high- temperature electronics applications, where its outstanding physical properties can be fully exploited. It exhibits an extremely high bandgap, very high carrier mobilities, high breakdown field strength, and the highest thermal conductivity of any wide bandgap material. LÄS MER

  7. 10. Secundum atrial septal defect in the adult. Clinical, haemodynamic and electrophysiological aspects

    Författare :Ulf Thilén; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; clinical outcome; atrial fibrillation; Atrial septal defect; atrial conduction; remodelling.;

    Sammanfattning : Atrial septal defect (ASD) is the most common congenital heart malformation diagnosed in adult life. In this thesis important clinical, haemodynamic and electrophysiological aspects of ASD in the adult are explored. LÄS MER
