  1. 1. Nucleator-driven assembly of curli organelles and their pathophysiological role in E. coli septic shock

    Författare :Zhao Bian; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Assembly; Curli; NOS2; Nucleator; Sepsis;

    Sammanfattning : The understanding of how polymeric surface structures are assembled in bacteria is one of general interests, which can provide insight into details of macromolecule interactions, and study how proteins fold into domains as assembly modules for building organelles. Protein-protein interactions in various subcellular compartments lead to the assembly of fimbriae at bacterial cell surfaces. LÄS MER

  3. 2. Outcomes of surgery for oesophageal cancer with focus on fatigue

    Författare :Zhao Cheng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Oesophageal cancer is the 6th leading cause of cancer mortality globally. Extensive surgery (oesophagectomy) with neoadjuvant chemo(radio)therapy is the backbone of curative treatment for oesophageal cancer. The thesis aimed to provide better knowledge of survivorship after oesophagectomy, focusing on cancer-related fatigue. LÄS MER

  4. 3. Atomistic Modelling of Materials for Clean Energy Applications : hydrogen generation, hydrogen storage, and Li-ion battery

    Författare :Zhao Qian; Rajeev Ahuja; Börje Johansson; Antonio Ferreira da Silva; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renewable energy; Materials science; Hydrogen production; Hydrogen storage; Li-ion battery; Density functional theory; SRA - Energy; SRA - Energi; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

    Sammanfattning : In this thesis, a number of clean-energy materials for hydrogen generation, hydrogen storage, and Li-ion battery energy storage applications have been investigated through state-of-the-art density functional theory.As an alternative fuel, hydrogen has been regarded as one of the promising clean energies with the advantage of abundance (generated through water splitting) and pollution-free emission if used in fuel cell systems.

  5. 4. Interference Alignment with Imperfect Channel Knowledge and Secrecy Constraints

    Författare :Zhao Wang; Mikael Skoglund; Ming Xiao; Sheng Yang; KTH; []
    Nyckelord :Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : In this thesis, the degrees of freedom (DOF) of wireless networks are studied with imperfect channel state information at transmitters (CSIT) and/or secrecy constraints. Different interference alignment schemes are proposed to establish the DOF lower bound for a variety of wireless networks. LÄS MER

  7. 5. Functional studies of deubiquitinating enzymes

    Författare :Bin Zhao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The attachment of ubiquitin to substrate proteins is a key process in regulating cellular events such as cell cycle progression, signal transduction, differentiation, apoptosis, and the clearance of misfolded or aberrant proteins. Like other post-translational modifications, ubiquitination is also reversible. LÄS MER
