  2. 21. Permafrost Groundwater Dynamics : Modeling of vertical and lateral flows in the active layer across multiple scales

    Author : Alexandra Hamm; Andrew Frampton; Peter Kuhry; Jeffrey McKenzie; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; permafrost; climate change; numerical modeling; hydrogeology; groundwater; naturgeografi; Physical Geography;

    Abstract : Hydrological processes in the Arctic are profoundly influenced by the presence of permanently frozen ground, known as permafrost. Conversely, permafrost is greatly affected by hydrological changes resulting from climate change. READ MORE

  4. 22. Towards the Limits – Climate Change Aspects of Life and Health in Northern Sweden : studies of tularemia and regional experiences of changes in the environment

    Author : Maria Furberg; Maria Nilsson; Anders Johansson; Lars Weinehall; Peter Friberg; Umeå universitet; []
    Keywords : Climate change; public health; Indigenous peoples; Sami; reindeer herding; resilience; tularemia; mixed-methods; infectious disease; seroprevalence; ELISA; outbreak investigation; risk factor; ecology; Francisella tularensis; Epidemiology; epidemiologi; folkhälsa; Public health;

    Abstract : BackgroundIndigenous peoples with traditional lifestyles worldwide are considered particularly vulnerable to climate change effects. Large climate change impacts on the spread of infectious vector-borne diseases are expected as a health outcome. READ MORE

  5. 23. Multiple forces drive the Baltic Sea food web dynamics and its response to environmental change

    Author : Susa Niiranen; Thorsten Blenckner; Olle Hjerne; Mike Elliott; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; climate change; Ecopath with Ecosim; food web interactions; multiple drivers; regime shift; trophic control; Marine Ecology; marin ekologi;

    Abstract : Understanding the interaction of multiple drivers and their compounded effects on ecosystem dynamics is a key challenge for marine resource management. The Baltic Sea is one of the world’s seas most strongly impacted by effects from both human activities and climate. READ MORE

  6. 24. Deep Learning for Wildfire Progression Monitoring Using SAR and Optical Satellite Image Time Series

    Author : Puzhao Zhang; Yifang Ban; Lorenzo Burzzone; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Remote Sensing; Deep Learning; Wildfire; Burned Area Mapping; Synthetic Aperture Radar; Change Detection; Segmentation; Optical and Radar Image Analysis; Sentinel-1; Sentinel-2; fjärranalys; djup inlärning; skogsbrand; kartläggning av brända områden; Synthetic Aperture Radar; upptäckt av förändringar; segmentering; analys av optiska och radarbilder; Sentinel-1; Sentinel-2; Geoinformatik; Geoinformatics;

    Abstract : Wildfires have coexisted with human societies for more than 350 million years, always playing an important role in affecting the Earth's surface and climate. Across the globe, wildfires are becoming larger, more frequent, and longer-duration, and tend to be more destructive both in lives lost and economic costs, because of climate change and human activities.

  7. 25. Developmental Aspects of Drug Transport Across the Blood-Brain Barrier

    Author : Jörgen Bengtsson; Margareta Hammarlund-Udenaes; Ann-Cathrin Engwall; Sven Björkman; Elizabeth C.M. de Lange; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood-brain barrier; development; active transport; tight junction proteins; microdialysis; recovery; morphine; nitrofurantoin; Bcrp; microarray; real-time PCR; in vitro; in vivo; LC-MS MS; Biopharmacy; Biofarmaci; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Abstract : The developmental aspect of drug transport across the blood-brain barrier (BBB) was investigated. Microdialysis was used to study unbound morphine BBB transport at different ages in sheep. An in vitro study was performed to find differentially expressed genes in brain capillary-rich fractions of the brain in rats of different ages. READ MORE
