4. 8. A sub-5 fs 100 TW optical parametric synthesizer

   Författare :Peter Fischer; Laszlo Veisz; Ove Axner; Cord L. Arnold; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical parametric amplification OPA ; optical parametric synthesizer OPS optimization; energy stability; carrier envelop phase stability; temporal intensity contrast; saturation; fewcycle; tera watt; fysik; Physics;

   Sammanfattning : State-of-the-art ultrashort light sources in the visible and near-infrared spectral regions provide direct access to the femtosecond realm, thereby enabling understanding and control of electronic processes within matter. On the other hand, ultra-intense light pulses lead to the emergence of relativistic electron motion and many related phenomena, such as electron & ion acceleration and high-order harmonic generation in plasmas.

5. 9. Sub-lethal Effects of Anthropogenic Contaminants on Aquatic Invertebrates

   Författare :Warren Kunce; Frank Johansson; Jan Örberg; Sarah Josefsson; Jes Rasmussen; Uppsala universitet; []
   Nyckelord :ecotoxicology; sub-lethal; behavior; biomarkers; thermal tolerance; pesticides; pyrethroids; neonicotinoids; pharmaceuticals; antihistamines; microplastics; mixtures; freshwater; invertebrates; chironomids; damselflies; snails; Biology with specialization in Animal Conservation; Biologi med inriktning mot zoologisk bevarandebiologi;

   Sammanfattning : Anthropogenic contaminants are considered to play a substantial role in the decline of freshwater invertebrate diversity. Sub-lethal effects of many of these contaminants on behaviour and life-history traits of aquatic invertebrates may contribute to their decline. LÄS MER

7. 10. Waterborne Carbon in Northern Streams : Controls on dissolved carbon transport across sub-arctic Scandinavia

   Författare :Elin Jantze; Steve W. Lyon; Georgia Destouni; Helen Dahlke; Pirkko Kortelainen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissolved carbon; DOC; DIC; TOC; sub-arctic; hydrology; Abisko; Physical Geography; naturgeografi;

   Sammanfattning : Waterborne carbon (C) forms an active and significant part of the global C cycle, which is important in theArctic where greater temperature increases and variability are anticipated relative to the rest of the globe withpotential implications for the C cycle. Understanding and quantification of the current processes governing themovement of C by connecting terrestrial and marine systems is necessary to better estimate future changes ofwaterborne C. LÄS MER
