  1. 1. DX Centers in AlGaAs

    Detta är en avhandling från Department of Solid State Physics, Lund University, Box 118, S-221 00 Lund, Sweden

    Författare :Yingbo Jia; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DX center; AlGaAs; GaAs AlGaAs multi-layer structures; C-V; DLTS; electric field dependence; positive-U and negative-U models; Schottky diodes; Halvledarfysik; Fysicumarkivet A:1996:Jia; Semiconductory physics; silicon; metastable states.;

    Sammanfattning : This thesis presents a study of DX center related phenomena in silicon doped AlGaAs and in GaAs/AlGaAs multi-layer structures. A variety of experimental techniques such as capacitance-voltage (C-V), deep level transient spectroscopy (DLTS), single shot capacitance, thermally stimulated capacitance (TSCAP), admittance spectroscopy, photocapacitance, and photoconductivity have been used.

  2. 2. Anorectal Malformations Long-term outcome and aspects of secondary treatment

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Johan Danielson; Uppsala universitet.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anorectal malformation; faecal incontinence; long-term outcome; Krickenbeck; NASHA Dx;

    Sammanfattning : Faecal incontinence (FI) is defined as the inability to control bowel movements. The causes of FI are many and diverse. One of the more uncommon reasons for FI is Anorectal Malformations (ARMs). An ARM is a congenital anomaly that affects somewhere between 1/2500 and 1/5000 live born babies. LÄS MER

  3. 3. From Particle-Production Cross Sections to KERMA and Absorbed Dose for the Case 96 MeV n-12C Interactions

    Sammanfattning : Neutron-carbon interactions have been studied with a focus on charged-particle production of relevance to radiation protection and medical applications, such as cancer therapy. The measurements have been performed using the particle-detection setup, MEDLEY, and the 96 MeV neutron beam at the The Svedberg Laboratory in Uppsala. LÄS MER

  4. 4. Distribution of CGRP and CGRP receptor in the trigeminovascular system and CNS

    Detta är en avhandling från Medicine (Lund)

    Författare :Sajedeh Eftekhari; Lunds universitet.; Lund University.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CGRP; CLR; RAMP1; migraine; trigeminovascular system; pain; cerebellum;

    Sammanfattning : Calcitonin gene-related peptide (CGRP) has a key role in the pathophysiology of migraine and is associated with activation of the trigeminovascular system. Recently, CGRP receptor antagonists have been developed with clinical efficacy. LÄS MER

  5. 5. Myocardial ischemia-reperfusion and cardioprotection. A study with microdialysis in a porcine model

    Detta är en avhandling från Department of Anaesthesiology and Intensive Care, Lund

    Författare :Carsten Metzsch; Lunds universitet.; Lund University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heart preservation; metoprolol; levosimendan; beta-blockers; pharmacological preconditioning; myocardial ischemia; cardioprotection; glycerol; microdialysis; cold cardioplegic storage;

    Sammanfattning : The studies in this thesis are based on questions raised in the clinical setting. Perioperative myocardial ischemia occurs more often than recognized. This may lead to myocardial infarction, increased morbidity, mortality, and health care costs. LÄS MER
