  1. 6. Modelling the Evolution of Species’ Ranges

    Författare :Martin Eriksson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Range expansions; Range margins; Population genetics; Evolutionary biology; Local adaptation; Environmental selection; Phenotypic plasticity; Computer simulations;

    Sammanfattning : The fact that species have limited ranges is often due to a limited ability to adapt to the environmental conditions that occur outside their geographic ranges. However, due to ongoing climate change, the environmental conditions within species’ geographic ranges may change in the near-future. LÄS MER

  3. 7. Photoluminescence Characteristics of III-Nitride Quantum Dots and Films

    Författare :Martin Eriksson; Per-Olof Holtz; Peder Bergman; Fredrik Karlsson; Volodymyr Khranovskyy; Yasuhiko Arakawa; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : III-Nitride semiconductors are very promising in both electronics and optical devices. The ability of the III-Nitride semiconductors as light emitters to span the electromagnetic spectrum from deep ultraviolet light, through the entire visible region, and into the infrared part of the spectrum, is a very important feature, making this material very important in the field of light emitting devices.

  4. 8. Att ta ställning : Gymnasieelevers argumentation och beslutsfattande om sociovetenskapliga dilemman

    Författare :Martin Eriksson; Carl-Johan Rundgren; Malin Ideland; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Science education; Socioscientific issues; SSI; Argumentation; Informal argumentation; Decision-making; Naturwissenschaftliche Unterricht; Naturvetenskaplig undervisning; Samhällsfrågor med naturvetenskapligt innehåll; SNI; Sociovetenskapliga dilemman; SSI; Argumentation; Beslutsfattande; Vargar; Dioxiner i fisk; Kemi; Chemistry;

    Sammanfattning : This thesis aims to explore students’ argumentation and decision-making relating to authentic socioscientific issues (SSI). The ability to make informed decisions about socio scientific issues has been recognized to be an important element in science education to achieve the goal of scientific literacy. LÄS MER

  5. 9. Impacts of Antifouling Compounds on Photosynthesis, Community Tolerance and psbA Genes in Marine Periphyton

    Författare :Martin Eriksson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PICT; antifouling; periphyton; photosynthesis; D1; psbA; tolerance; resistance; periphyton;

    Sammanfattning : Toxicants can act as selective pressures in the environment, eliminating sensitive genotypes or species and favouring tolerant ones. Such toxicant-induced selection can be detected in natura... LÄS MER

  7. 10. Nonresonant high-frequency actuation of carbon based nanoelectromechanical oscillators

    Författare :Martin Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoelectromechanical oscillators; graphene; nonresonant; mechanical vibra- tions; selective mode actuation;

    Sammanfattning : Carbon based nanoelectromechanical oscillators outperform their predecessors in many ways. In particular, their extraordinarily high quality factors make them very promising for sensor applications. To operate the nano oscillators, different kinds of actuation mechanisms are utilised, for instance direct or parametric resonance. LÄS MER
