  2. 1. Levels of organohalogen compounds in White-tailed sea eagles (Haliaeetus albicilla) in relation to reproduction impairment in the Bothnian Sea

    Author : Ulrika Nordlöf; Lillemor Asplund; Björn Helander; Yngve Zebuhr; Michael Mclachlan; Roland Kallenborn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : The white-tailed sea eagle (Haliaeetus albicilla) is in the top of the marine food chain and its existence in Sweden has been threatened several times. The species succeeded to recover from the deep decline in the 1970s when the exposure to persistent organic pollutants influenced the reproduction negatively. READ MORE

  4. 2. Climate vulnerability assessment methodology : Agriculture under climate change in the Nordic region

    Author : Lotten Wiréhn; Tina-Simone Schmid Neset; Björn-Ola Linnér; Giuseppe Feola; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agriculture; Assessment methodology; Climate change; Geographic Visualization; Indicator-based methods; Vulnerability; Bedömningsmetodologi; Geografisk Visualisering; Indikatorbaserade metoder; Jordbruk; Klimatförändringar; Sårbarhet;

    Abstract : Food security and climate change mitigation are crucial missions for the agricultural sector and for global work on sustainable development. Concurrently, agricultural production is directly dependent on climatic conditions, making climate change adaptation strategies essential for the agricultural sector. READ MORE

  5. 3. Forest for rest : recovery from exhaustion disorder

    Author : Elisabet Sonntag-Öström; Lisbeth Slunga Järvholm; Ann Dolling; Ylva Lundell; Maria Nordin; Marie Åsberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Burnout; nature-assisted therapy; rehabilitation; forestry; stress disorders; environmental medicine; restoration; human health; well-being; folkhälsa; Public health;

    Abstract : Background Exhaustion disorder (ED) is a common mental and behavioural disorder which often leads to severe negative consequences for the individual and the society. Natural environments have positive effects on mental, physiological and attentional recovery in stressed persons, which encouraged us to test if forest visits could improve recovery from ED.

  6. 4. Geochemical and mineralogical laboratory methods in waste rock drainage quality prediction

    Author : Teemu Karlsson; Lena Alakangas; Päivi Kauppila; Andrew Barnes; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extractive waste characterisation; drainage water; ARD; NRD; ABA test; NAG test; SEM; Applied Geochemistry; Tillämpad geokemi;

    Abstract : Harmful substances containing acid or neutral rock drainages (ARD and NRD) are a major challenge related to the management of extractive industry wastes. This issue is particularly related to deposits containing sulphide minerals, which are prone to oxidization under the influence of atmospheric oxygen and water. READ MORE

  7. 5. Improving the understanding of cloud radiative heating

    Author : Erik Johansson; Abhay Devasthale; Michael Tjernström; Annica M. L. Ekman; Robert Pincus; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; clouds; radiative effects; upper troposphere-lower stratosphere; atmospheric circulation; remote sensing; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Clouds play an essential role in regulating Earth’s radiation budget by reflecting and absorbing energy at different spectra. As they interact with radiation, they can radiatively heat or cool the adjacent atmosphere and the surface. READ MORE
