  2. 11. Galanin : a modulator of serotonin neurotransmission : relevance for depression

    Author : Haleh Razani; Karolinska Institutet; Karolinska Institutet; []
    Keywords : galanin; 5-HT1A receptors; 5-HT; 8-OH-DPAT; fluoxetine; robalzotan; passive avoidance; microdialysis; mRNA; KD values; Bmax values; depression;

    Abstract : Galanin is widely distributed throughout the central nervous system with multiple and diverse biological roles. In the rat, galanin-like immunoreactivity is expressed in a population of5-hydroxytryptamine (5-HT, serotonin) neurons in the dorsal raphe (DR) with extensive projections to the forebrain areas e.g., hippocampus.

  4. 12. Role of oxytocin in glucose homeostasis and weight gain

    Author : Eva Björkstrand; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The overall aim of this thesis was to study metabolic functions of oxytocin in particular in relation to glucose, insulin and glucagon. Application of oxytocin locally in the pancreas (microdialysis technique) increased insulin (RIA) and glucagon (RIA) release. READ MORE

  5. 13. Charge carrier traffic at interfaces in nanoeletronic structures

    Author : Bahman Raeissi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HfO2; oxide traps; High-k; interface states;

    Abstract : This thesis describes investigations in relation to the search for materials with high dielectric constant, k, for future CMOS transistors. The most elementary quantities to be considered are k-value and energy band offsets between the dielectric and the silicon crystal on which it is deposited. READ MORE

  6. 14. Metastable YAlN and ScAlN thin films : growth and characterization

    Author : Agnė Žukauskaitė; Lars Hultman; Jens Birch; Anita Lloyd Spetz; Linköpings universitet; []
    Keywords : ;

    Abstract : ScxAl1-xN and YxAl1-xN thin films were deposited in a ultra high vacuum system using reactive magnetron co-sputtering from elemental Al, Sc and Y targets in Ar/N2. Their mechanical, electrical, optical, and piezoelectrical properties were investigated with the help of transmission electron microscopy, xray diffraction, ellipsometry, I-V and C-V measurements, and two different techniques for piezoelectric characterization: piezoresponse force microscopy and double beam interferometry.

  7. 15. Modeling and electrical characterization of Cu(In,Ga)Se2 and Cu2ZnSnS4 solar cells

    Author : Christopher Frisk; Charlotte Platzer-Björkman; Jörgen Olsson; Janez Krč; Uppsala universitet; []
    Keywords : ;

    Abstract : In this thesis, modeling and electrical characterization have been performed on Cu(In,Ga)Se2 (CIGS) and Cu2ZnSnS4 (CZTS) thin film solar cells, with the aim to investigate potential improvements to power conversion efficiency for respective technology. The modeling was primarily done in SCAPS, and current-voltage (J-V), quantum efficiency (QE) and capacitance-voltage (C-V) were the primary characterization methods. READ MORE
