  1. 1. Protection for Multiterminal HVDC Grids - A Digital Contribution

    Författare :Ilka Jahn; Staffan Norrga; Hans-Peter Nee; Dirk Westermann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC transmission; power system protection; IED; real-time systems; test bench; field programmable gate array; open-source hardware; open-source software; power engineering education; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The aim of this thesis is to (1) enhance understanding of mechanisms that are important for the protection of high-voltage direct-current (HVDC) grids, and (2) suggest possible technical solutions. To that end, digital technologies were used both in simulation, as well as in a laboratory environment. LÄS MER

  3. 2. Early Environment, Adolescent Alcohol Drinking and Neurobiological Responses to Drugs

    Författare :Sara Palm; Ingrid Nylander; Anne-Lie Svensson; Lundblad Martin; Giancarlo Colombo; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescence; beta-endorphin; dopamine; dynorphin; endogenous opioids; enkephalin; high-speed chronoamperometry; housing conditions; maternal separation; multivariate concentric square field™ test; open field test; radioimmunoassay; voluntary alcohol intake; Wistar rats; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : Genes and environment interact to determine an individual’s vulnerability or resilience to several psychiatric disorders, including alcohol use disorder (AUD). Alcohol use is often initiated during adolescence and early onset drinking is associated with increased risk for later AUD. LÄS MER

  4. 3. Maternal Separation in Rats : An Experimental Model for Long-Term Effects of Early Life Experiences on Neurochemistry, Voluntary Ethanol Intake and Exploration and Risk Assessment Behavior

    Författare :Erika Roman; Ingrid Nylander; J. Dee Higley; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical pharmacology; Handling; Maternal Deprivation; Environment; Opioids; Dopamine; Alcohol; Stress; Concentric Square Field; Open Field; Elevated Plus-maze; Farmaceutisk farmakologi; Pharmaceutical pharmacology; Farmaceutisk farmakologi;

    Sammanfattning : The period of early life is important for the development of individual brain function and behavior. Human studies have shown altered vulnerability to develop psychopathology and/or excessive drug intake, possibly leading to dependence, as a consequence of early life experiences. LÄS MER

  5. 4. Diagnosing and monitoring open-angle glaucoma. Pupillometry and other novel techniques

    Författare :Lada Kalaboukhova; Göteborgs universitet; []
    Nyckelord :open-angle glaucoma; relative afferent pupillary defect; pupillometer; visual field; Frequency Doubling Technology Perimetry; High-pass Resolution Perimetry; Heidelberg Retina Tomography;

    Sammanfattning : Aim:To investigate the ability of a custom-built pupillometer and other novel diagnostic instruments to detect and monitor optic nerve damage in glaucoma.Methods:In the first two studies we investigated pupillary reactions to light in patients with glaucoma and in healthy persons using a custom-built pupillometer.

  7. 5. Individual differences in behavior, neurochemistry and pharmacology associated with voluntary alcohol intake

    Författare :Shima Momeni; Erika Roman; Bo Söderpalm; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intermittent access; multivariate concentric square field; open field; risk assessment; risk taking; individual difference; behavior; strain variation; endogenous opioid system; naltrexone; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : Alcohol use disorder is a worldwide public health problem and is a disorder with substantial individual variation. There are suggested links between various behavioral traits, comorbid psychiatric diseases and excessive alcohol consumption. LÄS MER
