  3. 12. Determination of the Critical Moisture Level for Mould Growth on Building Materials

    Författare :Pernilla Johansson; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crawl space; Fungus; Mould resistance; Wood; Building materials; Mould; Critical moisture level; Attic; Relative humidity; Cyclic conditions; Laboratory method;

    Sammanfattning : The susceptibility to mould growth varies between building materials. The factors that most affect mould growth, the relative humidity (RH) and temperature also vary in different parts of buildings. One way of preventing the growth of mould in buildings is therefore to choose building materials that can withstand the expected conditions. LÄS MER

  4. 13. Prefabricated composite bridges : a study of dry deck joints

    Författare :Robert Hällmark; Ian May; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge construction; prefabrication; monitoring; Steel Structures; Stålbyggnad;

    Sammanfattning : This thesis deals with prefabricated composite bridges in general, and prefabricated concrete deck elements with dry joints in particular.As outlined in Paper I and Chapter 2 prefabrication has several advantages over in situ construction, and has hence been discussed for decades in the construction business.

  5. 14. Överflöd och ofullbordan : Essä om det moderna

    Författare :Bo Isenberg; Sociologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; abstraction; abundance; classical modernity; contingency; crisis; modernity; oblivion; postmodernity; the principle of insufficient reason; religion; society; sociology; structivity; Sociology; tradition; cultural sociology; historical anthropology; Sociologi; Cultural anthropology; ethnology; Kulturantropologi; etnologi;

    Sammanfattning : The problem which the present study discusses is modernity. The study interprets modernity’s cultural and anthropological dispositions as historical appearances. Consequently, it is situated at the intersection of cultural sociology and historical anthropology. The aim is to generate insight and understanding rather than a coherent theory. LÄS MER

  7. 15. Simulation and Electrical Evaluation of 4H-SiC Junction Field Effect Transistors and Junction Barrier Schottky Diodes with Buried Grids

    Författare :Jang-Kwon Lim; Hans-Peter Nee; Mietek Bakowski; Ichiro Omura; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon carbide SiC ; junction field-effect transistors JFETs ; junction barrier schottky diode JBS ; schottky barrier diode SBD ; buried-grid BG technology; simulation; implantation; epitaxial growth; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Silicon carbide (SiC) has higher breakdown field strength than silicon (Si), which enables thinner and more highly doped drift layers compared to Si. Consequently, the power losses can be reduced compared to Si-based power conversion systems. Moreover, SiC allows the power conversion systems to operate at high temperatures up to 250 oC. LÄS MER
