  2. 1. Modeling mesoscopic unconventional superconductors

    Author : Patric Holmvall; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phase transitions; Andreev bound states; quasiclassical theory; mesoscopic thin-films; spontaneous symmetry breaking; time-reversal symmetry; Unconventional superconductivity; translational symmetry;

    Abstract : High-temperature superconducting materials are often experimentally realized as thin films that can be patterned into devices operating in the mesoscopic regime. On this length scale, various finite-size and surface effects heavily influence the nature of the superconducting state, and can induce new ground states with spontaneously broken symmetries.

  4. 2. Selfconsistent theory of superconductivity in unconventional superconductors

    Author : Fabian Schrodi; Peter M. Oppeneer; Alex Aperis; Jörg Schmalian; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; superconductivity; unconventional; Eliashberg theory;

    Abstract : Superconductivity is broadly believed to stem from either electron-phonon interaction (EPI) or from purely electronic mechanisms, such as antiferromagnetic spin fluctuations. For many materials the discussion about which of these interactions is the dominant "pairing glue" is still ongoing. READ MORE

  5. 3. World oil supply and unconventional resources : Bottom-up perspectives on tight oil production

    Author : Henrik Wachtmeister; Mikael Höök; Roger Bentley; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; oil supply; oil production; unconventional resources; tight oil; shale oil; bottom-up model; projections; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Abstract : Oil is the world’s largest primary energy source. It dominates the transportation sector which underpins the world economy. Yet, oil is a nonrenewable resource, destined not to last forever. In the mid-2000s global conventional oil production stagnated, leading to rising oil prices and fears of permanent oil scarcity.

  6. 4. "English Philology is just a Bubble" : Unconventional Metaphors in English as a Lingua Franca

    Author : Sebastian Malinowski; Andrea C. Schalley; Erica Sandlund; Marie Tåqvist; Hans-Jörg Schmid; Karlstads universitet; []
    Keywords : HUMANIORA; HUMANITIES; unconventional metaphors; creativity; conceptual metaphor theory; English as a lingua franca; objectivity; survey; FrameNet; English; Engelska;

    Abstract : The present thesis investigates unconventional metaphors in English as a Lingua Franca (ELF). Empirical approaches in metaphor research have gained prominence, yet methodologies could benefit from more transparent procedural descriptions and efforts to decrease researcher intuition in the data analysis.

  7. 5. Unconventional T cells in colon adenocarcinomas

    Author : William Rodin; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Unconventional T cells; MAIT cells; γδ T cells; Colorectal cancer; Tumour immunity;

    Abstract : Many factors influence the initiation and growth of tumours. The infiltration and activity of immune cells in the tumour microenvironment are widely recognised as key factors affecting the clinical outcome of cancer. READ MORE
