  1. 1. Atomic Scale Characterization of III-V Nanowire Surfaces

    Författare :Johan Knutsson; NanoLund: Centre for Nanoscience; []
    Nyckelord :III–V semiconductor materials; nanowire; surface; scanning tunneling microscopy; wurtzite; zinc blende; scanning tunneling spectroscopy; Fysicumarkivet A:2017:Knutsson;

    Sammanfattning : This dissertation focus on the atomic-scale characterization of the surface properties and electronic structure of III–V semiconductor nanowires (NWs). Since the early 2000s, the fabrication and characterization of III–V NWs has been a very significant topic within material science due to their potential for applications in lighting, energy harvesting, and electronics.

  3. 2. Morphology and biochemistry of the tympanic membrane in relation to retraction pathology

    Författare :Johan Knutsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Tympanic membrane; retraction pathology; secretory otitis media; cholesteatoma; pars tensa; lamina propria; keratinizing epithelium; collagen type; progenitor cells; stem cells; immunohistochemistry; electron microscopy;

    Sammanfattning : Otitis media is very common during childhood and may predispose for tympanic membrane (TM) pathology later in life. Therefore, it is important to investigate the possible changes in TMs subjected to otitis media. There is evidence of a relationship between previous otitis media and TM retraction disease. LÄS MER

  4. 3. Folkliga möbler : tradition och egenart : en stilanalytisk studie av renässans- och barockdrag i den svenska folkliga möbelkonsten

    Författare :Johan Knutsson; Mårten Snickare; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; vernacular art; folk art; furniture design; craftsmanship; style; Möbelkonst; Folkkonst; Sverige; 1600-talet; 1700-talet; konstvetenskap; Art History;

    Sammanfattning : A collection of furniture, most of which was produced before 1770, forms the basis of this description and explanation of the characteristics distinguishing vernacular furniture from bourgeois furniture, and the vernacular furniture in one area from that in another. The vernacular material is used to test the convincing force of the art history terms created to describe the artistic expression of the upper-class culture. LÄS MER

  5. 4. Tools for Designing Mobile Interaction with the Physical Environment in Outdoor Lessons

    Författare :Johan Eliasson; Teresa Cerratto Pargman; Robert Ramberg; Ola Knutsson; Lyn Pemberton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human-Computer Interaction; Design Tools; Concept-Driven Design; Mobile Learning; Design-Based Research DBR ; Outdoor Lessons; Field Trips; Design Theory; Design Process; Distraction; Man-Machine-Interaction MMI ; människa-maskin-interaktion MMI ;

    Sammanfattning : Mobile technologies are increasingly being used to support students in outdoor learning activities. For instance, in a growing number of research projects, smartphones and positioning technologies are being used to support students in exploring the natural environment. LÄS MER

  7. 5. Remedial Injection Grouting of Embankment Dams with Non-Hardening Grouts

    Författare :Johan Lagerlund; Håkan Stille; Sven Knutsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The focus of this thesis is to study the possibility of injection grouting of embankment dams affected by internal erosion. Internal erosion is a process where certain soil material from an embankment dam is removed. This phenomenon occurs in the central core of the embankment dam. LÄS MER
