  1. 1. Where Scholars are Made : Gendered Arenas of Persona Formation in Finnish Folkloristics, 1918–1932

    Författare :Lisa Svanfeldt-Winter; Kirsti Niskanen; Marja-Liisa Keinänen; Annika Berg; Elise Garritzen; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Scholarly persona; gender; Finnish history; history of folklore; history of humanities; history of knowledge; students; History; historia;

    Sammanfattning : This dissertation investigates how two Finnish folklorists, Elsa Enäjärvi (1901–1951) and Martti Haavio (1899–1973), obtained information about perceptions of what constituted good and acknowledged scholars and how they responded to these implicit and explicit expectations and requirements. The dissertation uses the concept of scholarly persona as an analytical tool to identify notions of good scholars as well as Enäjärvi’s and Haavio’s processes to form themselves as such. LÄS MER

  3. 2. From behaviour to genes: anti-predator responses of brown trout (Salmo trutta) under winter conditions

    Författare :Karl Filipsson; Eva Bergman; Ann Erlandsson; Martin Österling; Johan Watz; Stefán Óli Steingrímsson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; burbot; climate change; cortisol; diel behaviour; gene expression; HPI axis; light; mRNA; piscivorous; poikilotherm; predator; salmonid; stream; stress; temperature; thermal; winter behaviour; Biology; Biologi;

    Sammanfattning : Temperature has major effects on the performance of poikilotherms. In encounters with predators, low winter temperatures constrain predator detection and escape capabilities in prey fishes. LÄS MER

  4. 3. Salmonid behaviour under winter conditions

    Författare :Johan Watz; Larry Greenberg; Eva Bergman; John Piccolo; Richard Cunjak; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; drift; energy budget; foraging; grayling; ice cover; lotic; metabolic rate; predation; salmon; stream; stress; temperature; trout; Biology; Biologi;

    Sammanfattning : Winter conditions are believed to play an important role in the population dynamics of northern temperate stream fish, challenging the ability of fish to physiologically and behaviourally adapt. Climate change is predicted to increase both mean temperature and temperature fluctuations, especially during winter, leading to dynamic environmental conditions in terms of river ice production and flow.

  5. 4. Ash chemistry and fuel design focusing on combustion of phosphorus-rich biomass

    Författare :Nils Skoglund; Dan Boström; Rainer Backman; Franz Winter; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phosphorus; biomass; combustion; ash chemistry; fuel design; ash transformation; phosphorus-rich; ash-forming elements; fuel fingerprint; ash transformation reactions; Lewis base; Lewis acid; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : Biomass is increasingly used as a feedstock in global energy production. This may present operational challenges in energy conversion processes which are related to the inorganic content of these biomasses. As a larger variety of biomass is used the need for a basic understanding of ash transformation reactions becomes increasingly important. LÄS MER

  7. 5. Towards Safer Lithium-Ion Batteries

    Författare :Marie Herstedt; Kristina Edström; Martin Winter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; lithium-ion batteries; photoelectron spectroscopy; surface film; thermal stability; electrolyte additive; graphite; lithium iron phosphate; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Surface film formation at the electrode/electrolyte interface in lithium-ion batteries has a crucial impact on battery performance and safety. This thesis describes the characterisation and treatment of electrode interfaces in lithium-ion batteries. LÄS MER
