  1. 1. Wheelchair Passengers and Local Public Transport Vehicles: Perceptions of Safety and Comfort

    Author : Anders Wretstrand; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road transport technology; Public transport; Bus; STS; Perception; Comfort; Wheelchair users; Safety; Vägtransportteknik; Care and help to handicapped; Handikappade; vård och rehabilitering;

    Abstract : Eliciting wheelchair-seated passengers’ perspective of safety and comfort is both useful and mandatory, particularly for researchers, clinicians, transit authorities, and for operators during purchase and use of vehicle technologies in existing and planned future transport systems. Therefore, the overarching objective of this thesis was to delineate the question of safety and comfort as perceived by wheelchair-seated passengers using public transport road vehicles. READ MORE

    Abstract : Recent research demonstrated that besides a role in sex determination and male fertility, the Y chromosome is involved in additional functions including prostate cancer, sex-specific effects on the brain and behaviour, graft-versus-host disease, nociception, aggression and autoimmune diseases. The results presented in this thesis include an analysis of sex-biased genes encoded on the X and Y chromosomes of rodents. READ MORE

  3. 3. Scanning tunneling microscopy and photoemission studies of Ag films on metal/semiconductor surfaces

    Author : Samuel Starfelt; Hanmin Zhang; Lars Johansson; Anders Mikkelsen; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Quantum well states; thin films; semiconductor; STM; STS; ARPES; Physics; Fysik;

    Abstract : The research presented in this thesis has been focused on the study of thin Ag films, grown on metal-reconstructed Si(111) and Ge(111) surfaces.The films have been grown at room temperature, and the morphologiesand electronic structures of the films have been investigated using scanning tunneling microscopy and spectroscopy (STM/STS), low-energy electron diffraction (LEED) and angle-resolved photoelectron spectroscopy(ARPES).

  4. 4. Citeringens praktiker: Det vetenskapliga publicerandet som teori, metod och forskningspolitik : The practices of the citation: Scientific publication as theory, method and research policy

    Author : Gustaf Nelhans; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : SAMHÄLLSVETENSKAP; HUMANIORA; SOCIAL SCIENCES; HUMANITIES; performativitet; citeringskultur; citeringsmangel; citeringspraktiker; citeringsnätverk; citeringstypologi; vetenskapstepori; vetenskapsstudier; vetenskaps- och teknikstudier; performativity; citation practices; citation; mangle; citation culture; citation networks; HistCite; citation map; historiograph; ontology; controversy; Science and Technology Studies; STS; Theory of science;

    Abstract : The thesis investigates the scientific citation and its various functions in the scientific community and develops it as a tool for research in theory of science, scientometrics and science studies. Based on empirical and theoretical studies that utilize both qualitative and quantitative methods the citation’s history, method, as well as its use in research policy is examined. READ MORE

  5. 5. Thin Mn silicide and germanide layers studied by photoemission and STM

    Author : Joakim Hirvonen Grytzelius; Lars Johansson; Hanmin Zhang; Leif Johansson; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Semiconductor surfaces; Si 111 ; Ge 111 ; manganese; Mn; silicides; germanides; atomic structure; electronic structure; magnetic properties; LEED; ARPES; XPS; core-level spectroscopy; STM; STS; XMCD; Physics; Fysik;

    Abstract : The research presented in this thesis concerns experimental studies of thin manganese silicide and germanide layers, grown by solid phase epitaxy on the Si(111)7×7 and the Ge(111)c(2×8) surfaces, respectively. The atomic and electronic structures, as well as growth modes of the epitaxial Mn-Si and Mn-Ge layers, were investigated by low-energy electron diffraction (LEED), angle-resolved photoelectron spectroscopy (ARPES), core-level spectroscopy (CLS), and scanning tunneling microscopy and spectroscopy (STM and STS).
