  1. 1. Influence of MHC class I peptide interaction on antigen presentation in normal and malignant cells

    Författare :Qian-Jin Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cytotoxic T lymphocytes; Natural Killer cells; Epstein-Barr virus; MHC class I; class I binding motifs; T cell receptor; antigen presentation; immunodominance;

    Sammanfattning : The presentation of MHC class I peptide complexes in normal and malignant cells was studied. An HLA A11 binding motif was defined by comparing synthetic peptide analogues of a known cytotoxic T Iymphocyte (CTL) target epitope for induction of surface A11 expression and triggering of cytotoxic activity.

  3. 2. Pastoralists and the Environmental State : A study of ecological resettlement in Inner Mongolia, China

    Författare :Qian Zhang; Bo Malmberg; Andrew Byerley; Richard Black; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Environmentalisation; political ecology; grassland degradation; migration decision-making; pastoralism; environmental migration; environmental governance; China; Geography with Emphasis on Human Geography; geografi med kulturgeografisk inriktning;

    Sammanfattning : China's quest for sustainable development has given birth to a set of contested ‘ecological construction’ programmes. Focusing on ‘ecological resettlement’, a type of policy measure in a programme for restoring degraded grasslands, this thesis sets out a critical analysis in opposition to the dominant technical and managerial approaches to understanding environmentalisation.

  4. 3. Spatial-Temporal Patterns of Urban Growth in Shanghai, China: Monitoring, Analysis, and Simulation

    Författare :Qian Zhang; Yifang Ban; Jiyuan Liu; Bin Jiang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urban growth; spatial-temporal pattern; remote sensing; spatial metrics; scenarios-based simulation; Shanghai; Geoengineering; Geoteknik;

    Sammanfattning : Supporting huge population, megacities are definitely the hot spots of production, consumption, and waste generation. Without careful investment and planning, megacities will be overwhelmed by burgeoning negative impacts on the environment, natural resources, and human health, as well as a host of social and economic issues.

  5. 4. Studies of Voltage Losses in Organic Solar Cells

    Författare :Deping Qian; Fengling Zhang; Feng Gao; Olle Inganäs; Natalie Stingelin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Organic photovoltaic (OPV) devices based on semiconducting polymers and small molecules are potential alternatives to inorganic solar cells, owing to their advantages of being inexpensive, lightweight, flexible and suitable for roll-to-roll production. The state of art organic solar cells (OSCs) performed power conversion efficiencies (PCEs) over 13%. LÄS MER
