  1. 1. Fault location in resonant earthed medium voltage distribution systems

    Författare :Md Zakaria Habib; Nathaniel Taylor; Mohamed F. Abdelfattah; Matti Lehtonen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical distribution; Distribution network; Reliability; SAIDI; Fault location; FL; Fault passage indicator; FPI; Compensated neutral; Resonant earthing; Resonant grounding; Petersen coil; Arc suppression coil.; Distributionsnät; Tillförlitlighet; Fellokalisering; FL; Felpassageindikation; FPI; Kompenserat nät; Spoljordat nät; Petersenspole.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : A major challenge in electric distribution systems is to increase the reliability of the electricity supply in an economical way. At the final medium-voltage level in the system, such as 10 kV or 20 kV, a single feeder may supply tens of medium/low-voltage transformers and hundreds of customers, with many branches of lines and cables where faults can occur.

  2. 2. The Francisella pathogenicity island : its role in type VI secretion and intracellular infection

    Författare :Lena Meyer; Anders Sjöstedt; Siobhan C. Cowley; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella; FPI; Type VI Secretion; Igl; DotU; VgrG; Pdp; microinjection; phagosomal escape; intracellular replication; Clinical Bacteriology; klinisk bakteriologi;

    Sammanfattning : Intracellular bacteria have developed various mechanisms to enter and persist in host cells and, at the same time, to evade the host immune response. One such pathogen is Francisella tularensis, the etiological agent of tularemia. LÄS MER

  3. 3. Nature and the Social Sciences : Examples from the Electricity and Waste Sectors

    Författare :Mikael Klintman; Sociologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ecology; critical realism; electricity; environment; epistemology; green identity; greening; meta-theory; nature; ontology; social science; public participation; waste; windpower; sociology; Sociologi;

    Sammanfattning : The book has two interrelated objectives. One objective is meta-theoretical and concerns the exploration of theoretical debates connected to issues of studying society and environmental problems; another objective is empirical/analytical, referring to the analysis of "green" public participation in the electricity and waste sectors in Sweden, and partly in the Netherlands as well as the UK.

  4. 4. Risk factors for atrial fibrillation in population-based studies : Epidemiological perspectives

    Författare :Linda Johnson; Internmedicin - epidemiologi; []
    Nyckelord :Atrial fibrillation; Fasting plasma insulin; forced expiratory volume; glucose; hypertension; lung volumes; population; premature atrial contractions; risk factors; spirometry; supraventricular extrasystoles; supraventricular tachycardias systolic blood pressure; weight;

    Sammanfattning : Atrial fibrillation (AF) is common among the elderly, and has serious consequences such as stroke and increased mortality. Not all of the population attributable risk for AF is explained by known risk factors. LÄS MER

  5. 5. The Role of Cyclooxygenase-2 in Models of Epilepsy and Traumatic Brain Injury : Effects of Selective Cyclooxygenase-2 Inhibitors

    Författare :Tina Kunz; Tadeusz Wieloch; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Controlled cortical contusion injury; fluid percussion injury; limbic seizures; nuclear factor-kappa B; prostaglandin metabolism; TUNEL staining; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : Cyclooxygenase-2 (COX-2) catalyses prostaglandin synthesis from arachidonic acid during inflammation. COX-2 is expressed in the normal brain and is induced in neurological disorders. There is evidence that COX-2 is involved in secondary events leading to cell death in the brain. LÄS MER
