1. 1. From Macroscopic to Microscopic Dynamics of Superconducting Cavities

   Författare :Anirban Bhattacharyya; Vitaliy Goryashko; Volker Ziemann; Roger Ruber; Jean Delayen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superconducting cavity; superconductivity; self-excited loop; Ginzburg-landau; vortex; optimization; quality factor; microwave; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : Superconducting (SC) radio frequency (RF) cavities are at the heart of many large-scale particle accelerators such as the European Spallation Source (ESS), the X-ray Free Electron Laser (XFEL), the Linac Coherent Light Source (LCLS)-II and the proposed International Linear Collider (ILC). The SC cavities are essentially resonant structures with very high intrinsic quality factors (Q0) of the order of 1010. LÄS MER

3. 2. Plasma and Dust at Saturn's Icy Moon Enceladus and Comet 67P/Churyumov-Gerasimenko

   Författare :Ilka. A. D. Engelhardt; Anders I. Eriksson; Yoshifumi Futaana; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

   Sammanfattning : Saturn’s moon Enceladus and comet 67P/Churyumov-Gerasimenko both are examples of icy solar system objects from which gas and dust flow into space. At both bodies, the gas becomes partly ionized and the dust grains get charged. LÄS MER

4. 3. Productivity and carbon transfer in pelagic food webs in response to carbon, nutrients and light

   Författare :Carolyn Faithfull; Ann-Kristin Bergström; Tobias Vrede; Kathryn Cottingham; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacterial production; phytoplankton production; mesocosms; food webs; carbon; nutrients; light; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; limnologi; Limnology;

   Sammanfattning : Some of the major problems we face today are human induced changes to the nitrogen (N), phosphorus (P) and carbon (C) cycles. Predicted increases in rainfall and temperature due to climate change, may also increase dissolved organic matter (DOM) inflows to freshwater ecosystems in the boreal zone. LÄS MER

5. 4. Applying proteomics and metabolomics for studying human skeletal muscle with a focus on chronic trapezius myalgia

   Författare :Jenny Hadrévi; Albert Crenshaw; Fatima Pedrosa-Domellöf; Fredrik Hellström; Bijar Ghafouri; Mary F Barbe; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Trapezius myalgia; proteomics; 2D-DIGE; metabolomics; microdialysate; biopsies; anatomi; Human Anatomy;

   Sammanfattning : Work related musculoskeletal disorders are the dominating causes of reported ill-health in industrialized countries. These chronic pain conditions are one of the most costly public health problems in Europe and North America. LÄS MER

7. 5. Exploring connections in social-ecological systems : The links between biodiversity, ecosystem services, and human well-being in South Africa

   Författare :Maike Hamann; Reinette (Oonsie) Biggs; Belinda Reyers; Thomas Elmqvist; Fabrice DeClerck; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; complex adaptive systems; mapping; ecosystem service bundles; multidimensional human well-being; biodiversity loss; inequality; research frameworks; interdisciplinarity; natural resource management; sustainable development; Sustainability Science; vetenskap om hållbar utveckling;

   Sammanfattning : A key challenge of the Anthropocene is to advance human development without undermining critical ecosystem services. Central to this challenge is a better understanding of the interactions and feedbacks between biodiversity, ecosystem services and human well-being, which interact in dynamic and complex social-ecological systems.
