  1. 26. Exploring Unorthodox Aquaporins : Characterization of NbXIPs & AtNIPs

    Författare :Henry Ampah-Korsah; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aquaporins; XIPs; NIPs; Phosphorylation; Pichia pastoris; Overexpression; boric acid; membrane proteins;

    Sammanfattning : AbstractAquaporins are membrane integral proteins that facilitate the transport of waterand/or other small neutral molecules across biological membranes in cells in allforms of life. Among the subfamilies of aquaporins in higher plants, the X IntrinsicProteins (XIPs) are the most recently discovered subfamily and the leastcharacterized. LÄS MER

  3. 27. Students’ Reasoning about Learning and Well-being in School : On the epistemic privilege of Swedish early adolescent students

    Författare :Ylva Backman; Karin Sporre; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pedagogik; Education;

    Sammanfattning : The recent emphasis on performance in standardized testing of Swedish students is visible in reports from both national and international agencies. According to the reports, there has been a steep decline in the internationally measured performance of Swedish students in school since the 1990s. LÄS MER

  4. 28. Electronic Properties of Metal Oxide Films Studied by Core Level Spectroscopy

    Författare :Jan Hinnerk Richter; Anders Sandell; Håkan Rensmo; Anne Borg; Uppsala universitet; []
    Nyckelord :Physics; electron spectroscopy; metal oxide; chemical vapour deposition; ion insertion; metal organic; band alignment; zirconium; titanium; silicon; high k; Fysik;

    Sammanfattning : In this dissertation core level electron spectroscopy has been employed to study various aspects of metal oxide films grown under ultra-high vacuum conditions. Studies on in situ ion insertion of lithium into thin TiO2 systems were performed. LÄS MER

  5. 29. Throughput Analysis of Interfering Packet Radio Networks

    Författare :André Stranne; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; energy; collision; packet length; frequency hopping; throughput; successful packet reception probability; heterogeneous packet radio networks; interference analysis;

    Sammanfattning : In this thesis, a probabilistic framework is presented and used for analysis of the throughput of interfering packet-based radio networks, referred to as packet radio networks (PRNs). Previous research on the performance of PRNs covers a wide variety of systems and aspects in varying levels of detail. LÄS MER

  7. 30. Evaluation of Non-Metallic Inclusions after Deformation and Their Effect on the Machinability of Steel

    Författare :SHUO GUO; Pär Jönsson; Andrey Karasev; Anders Tilliander; Robert Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel; Heat treatment; REM-treat steel; Ce modification; Chip breakability; weight distribution of chips Non-metallic inclusions; Deformation; Electrolytic extraction; stål; värmebehandling; REM-behandlade stål; Ce modifiering; spånbrytning; viktsdistribution av spån; icke-metalliska inneslutningar; deformation; elektrolytisk extraktion.; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The presence of non-metallic inclusions (NMIs) have critical effects on both the mechanical properties and machinability of steels. In the present thesis, one focus is to study the characteristics of deformed sulfides (MnS) for a stainless steel (3R65) and a tool steel (42CrMo4). LÄS MER
