  1. 11. Modelling and controlling of polymer electrolyte fuel cell systems

    Författare :Yuanxin Qi; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis focuses on the modelling and controlling of polymer electrolyte fuelcell (PEFC) systems. A system level dynamic PEFC model has been developedto test the system performance (output voltage, reactants gas partial pressures,and stack temperature) for different operating conditions. LÄS MER

  3. 12. Inhibition of acute allogaft rejection - experimental transplant studies with biological and chemical immunosuppressants

    Författare :Zhongquan Qi; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; Immunology; tacrolimus; MNA; leflunomide; cyclosporine; drug effects; graft survival; immunosuppression; heart; animal; transplantation; Immunologi; serologi; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : In clinical transplantation immunosuppressive agents are used in combination with the objective to achieve additive effects and less toxicity. A large number of novel drugs are candidates for clinical introduction at this time and experiments in animal models have an important role to play. LÄS MER

  4. 13. Studies in the Dynamics of Science : Exploring emergence, classification, and interdisciplinarity

    Författare :Qi Wang; Ulf Sandström; Martin Meyer; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; science dynamics; bibliometrics; emerging research topics; interdisciplinary research; journal classification systems; cognitive distance; research policy;

    Sammanfattning : The dynamic nature of science is embodied in the growth of knowledge in magnitude and the transformation of knowledge in structure. More specifically, the growth in magnitude is indicated by a sharp increase in the number of scientific publications in recent decades. LÄS MER

  5. 14. Mobility Knowledge Graph and its Application in Public Transport

    Författare :Qi Zhang; Zhenliang Ma; Erik Jenelius; Carlos Lima Azevedo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knowledge graph; Smart card data; Public transport; User-station attention; Relation extraction; Transportvetenskap; Transport Science; Transportsystem; Transport Systems;

    Sammanfattning : Efficient public transport planning, operations, and control rely on a deep understanding of human mobility in urban areas. The availability of extensive and diverse mobility data sources, such as smart card data and GPS data, provides opportunities to quantitatively study individual behavior and collective mobility patterns.

  7. 15. Chromatin regulators and transcriptional control of Drosophila development

    Författare :Qi Dai; Mattias Mannervik; Albert J. Courey; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chromatin; Co-factors; Transcription; Development; Drosophila; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : The development of a multicellular organism is programmed by complex patterns of gene expression. In eukaryotic cells, genes are packaged by histone proteins into chromatin. Chromatin regulators often function as transcription co-factors. LÄS MER
