  4. 22. Iodine Isotopes and their Species in Surface Water from the North Sea to the Northeastern Atlantic Ocean

    Author : Peng He; Ala Aldahan; Per Roos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; iodine isotopes; 129I; 127I; oceans; North Sea; speciation; Atlantic Ocean; English Channel; Celtic Sea; AMS; iodine chemistry; geochemistry; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Abstract : Huge amounts of anthropogenic 129I have been and still are released to the environment through liquid and gaseous discharges from the nuclear fuel reprocessing facilities worldwide and in particular the ones in Europe. Most of this 129I signal has been accumulated in the marine environment which plays a major role in the iodine natural pool. READ MORE

  5. 23. High Order Finite Difference Methods with Artificial Boundary Treatment in Quantum Dynamics

    Author : Anna Nissen; Gunilla Kreiss; Sverker Holmgren; Magnus Svärd; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Schrödinger equation; finite difference methods; perfectly matched layer; summation-by-parts operators; adaptive discretization; stability; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : The investigation of the dynamics of chemical reactions, both from the theoretical and experimental side, has drawn an increasing interest since Ahmed H. Zewail was awarded the 1999 Nobel Prize in Chemistry for his work on femtochemistry. READ MORE

  6. 24. Radioanalytical chemistry in emergency preparedness

    Author : Ulrika Nygren; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Radioactive nuclides present a potential health hazard due to the ionising radiation emitted during their decay. The release of large amounts of radioactive nuclides is of concern both for man and the environment. READ MORE

  7. 25. Using airborne eDNA to study ecosystem dynamics

    Author : Edvin Karlsson; Per Stenberg; Mats Forsman; Tomas Brodin; Donald J Baird; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this era of global biodiversity crisis, the need to monitor ecological communities over space and time is more pressing than ever to effectively direct biodiversity conservation and management efforts. To understand the natural dynamics of an ecosystem, and the impact of anthropogenic activities related to environmental and climate change, long time series are needed to accurately link such processes to ecosystem change.
