  1. 1. Skogsrået, näcken och Djävulen : erotiska naturväsen och demonisk sexualitet i 1600- och 1700-talens Sverige

    Författare :Mikael Häll; Historia; []
    Nyckelord :HUMANIORA; HUMANITIES; nature spirit; demon; sexuality; devil; forest nymph; water spirit; troll; monster; incubus; succubus; magic; early modern; Sweden; popular belief; folklore; demonology; natural philosophy; witchcraft; bestiality; reformation; religion; crime; sin;

    Sammanfattning : This dissertation examines conceptions of erotic nature spirits and their association with demonic sexuality in 17th and 18th century Sweden. Its purpose is to reconstruct the various cultural and symbolic meanings which such notions had for the society of the day. LÄS MER

  3. 2. Information Thermodynamics and Fluctuations in Quantum Dots

    Författare :David Barker; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stochastic thermodynamics; Maxwell s demon; quantum dot; charge sensing; information; feedback; Fysicumarkivet A:2022:Barker;

    Sammanfattning : In small systems with large fluctuations, the classical description of thermodynamics is no longer sufficient which has led to the development of stochastic thermodynamics. One important result from stochastic thermodynamics is that with measurement and feedback it is possible to use those fluctuations to extract work from a single heat bath coupled to the system.

  4. 3. Phase transitions and vortex structures in multicomponent superconductors

    Författare :Karl Sellin; Egor Babaev; Astrid S. de Wijn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multicomponent superconductors; superconductivity; phase transitions; monte carlo; vortices; vortex structure formation; competing interactions;

    Sammanfattning : Theoretical aspects of multicomponent superconductivity and systemswith competing interactions are studied using Monte Carlo techniques.Motivated by recent experimental and theoretical results of complex struc-ture formation of vortices in multicomponent systems, possible vortex struc-ture formations due to vortex interactions that are not purely attractive orrepulsive are considered.

  5. 4. Diazotrophy and diversity of benthic cyanobacteria in tropical coastal zones

    Författare :Karolina Bauer; Birgitta Bergman; Paul K. Hayes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine cyanobacteria; benthic nitrogen fixation; diversity; diazotrophy; Lyngbya majuscula; Zanzibar; western Indian Ocean; Plant physiology; Växtfysiologi;

    Sammanfattning : Discoveries in recent years have disclosed the importance of marine cyano-bacteria in the context of primary production and global nitrogen cycling. It is hypothesized here that microbial mats in tropical coastal habitats harbour a rich diversity of previously uncharacterized cyanobacteria and that benthic marine nitrogen fixation in coastal zones is substantial.

  7. 5. Umeåsystemet : en studie i alternativ nykterhetspolitik 1915-1945

    Författare :Per Frånberg; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Temperance; non-industrial areas; Prohibition; populism; restrictions; social control;

    Sammanfattning : This dissertation deals with temperance in rural economically backward communities in the county of Västerbotten in Northern Sweden. Most Swedish historians have related the rapid break-through of organized temperance to industrialization and industrial areas. The connection temperance - industrialization is indisputable. LÄS MER
