  1. 21. Hydrogen Impurities and Dislocations in Transition Metals

    Författare :Björn von Sydow; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Motion of impurities and dislocations is essential for many material properties of metals. In the present thesis we have made use of different atomistic simulation techniques to study the behavior of hydrogen and edge dislocations in transition metals. We have carried out molecular-dynamics (MD) simulations for hydrogen diffusion in niobium. LÄS MER

  3. 22. The molecular basis of the development and diversity of proprioceptive neurons : a story of surviving and thriving

    Författare :Haohao Wu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Proprioception, also known as the sixth sense, describes the sensation of our body position and movement. Its proper function is essential for our daily activities from coarse movements, e.g. locomotion, to precise movements, e. LÄS MER

    Sammanfattning : This thesis deals with processes on integer partitions and their limit shapes, with focus on deterministic and stochastic variants on one such process called Bulgarian solitaire. The main scientific contributions are the following. LÄS MER

  5. 24. Fabrication and Characterization of Photon Radiation Detectors

    Författare :Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Mikael Lindeberg; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Detectors; Posistion Sensitive Detectors; Electronics; Elektronik;

    Sammanfattning : This thesis involves a study the fabrication and characterization of photon radiation detectors. The focus has been to develop and improve the performance of optical measurement systems, but also to reduce their cost. The work is based on the study of two types of detectors, the position sensitive detector and the thermal detector. LÄS MER

  7. 25. Work experiences among healthcare professionals in the beginning of their professional careers : a gender perspective

    Författare :Birgit Enberg; Ann Öhman; Gunnevi Sundelin; Karin Harms-Ringdahl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiotherapy; Sjukgymnastik fysioterapi;

    Sammanfattning : Swedish healthcare organizations have undergone substantial organizational and economic restructuring during the 1990s due to financial cutbacks. Little is known about recently graduated healthcare professionals´ work experience in healthcare and their future career preferences. LÄS MER
