  1. 1. Materials Reliability in PEM Fuel Cells

    Författare :Live Mølmen; Peter Leisner; Ulf Jansson; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cell; PEMFC; Bipolar plate; Catalyst; Electrodeposition; Corrosion; Stainless steel; Accelerated stress tests; bränsleceller; PEM; bipolära plattor; katalysator; elektroplätering; korrosion; accelererad testning;

    Sammanfattning : As part of the global work towards reducing CO2 emissions, all vehicles needs to be electrified, or fueled by green fuels. Batteries have already revolutionised the car market, but fuel cells are believed to be a key energy conversion system to be able to electrify also heavy duty vehicles. LÄS MER

  3. 2. Flotation-REST (Restricted Environmental Stimulation Technique) in the age of anxiety : Exploring the role and treatment applications of sensory isolation in the modern world

    Författare :Kristoffer Jonsson; Anette Kjellgren; Torsten Passie; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Flotation-REST; Sensory isolation; Sensory deprivation; Anxiety; Generalized anxiety disorder; Complementary and alternative medicine; Flyt-REST; sinnes-isolation; sensorisk deprivation; generaliserat ångest syndrom; komplementär och alternativ medicin; Psykologi; Psychology;

    Sammanfattning : Anxiety and the use of Complementary and Alternative Medicine (CAM), such as flotation-REST, have increased markedly during the last decades. Anxiety is reportedly a prevalent incentive for the use of CAMs, despite the present low state of knowledge about their safety and efficacy. LÄS MER

  4. 3. The visual ecology of bees - Tales of diverse eyes and behaviours

    Författare :Pierre Tichit; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal behaviour; Arthropods; Bumblebees; Compound Eyes; Crystalline cones; Flight control; Image analysis; Landing; Sensory ecology; Stingless bees; Vision; X-ray microtomography;

    Sammanfattning : The buzzing flight of bees is a popular summer hit. Yet, outside of a few familiar species of honeybees and bumblebees, these fantastic little creatures are still mostly unknown. With about twenty-five thousand species, bees are a very diverse group. They can be found in drastically different habitats. LÄS MER

  5. 4. Multiple stressors in rotifer communities: : Effects of predation, climate change, and brownification

    Författare :Huan Zhang; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate change; community dynamic; brownification; heat wave; inducible defense; rotifer; plasticity; multiple stressors; Predation; prey;

    Sammanfattning : Most organisms on Earth live in an environment where they are exposed to multiple pressures, including predation and climate change. In many aquatic ecosystems, organisms have to handle additional challenges such as brownification, co-occurring with climate warming. LÄS MER

  7. 5. Movement patterns and displacement of a soil insect

    Författare :Elna Nilsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; attraction; repellence; fatty acid; Ecology; Ekologi; alarm; autoregressive model; autocorrelation; random walk; Protaphorura armata; Collembola; migration; dispersal; movement; displacement;

    Sammanfattning : Movement and dispersal are important determinants of the spatial distribution and persistence of animal populations in a heterogeneous environment. I studied the small-scale movement pattern of a soil-living insect, Protaphorura armata (Collembola) by using a video-equipment. LÄS MER
