  2. 11. Fabrication, Simulation and Performance of Ultra-Thin Silicon Detectors-Development of a Detection System for Living Cell Irradiation

    Author : Naseem Salim; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Abdel; micro-fabrication technology; ultra-thin silicon detector; single ions; SIHF; ΔE detector;

    Abstract : For the development of a Single–Ion Hit Facility (SIHF) for living cells irradiation at the Lund Ion Beam Analysis facility (LIBAF), newly developed pre-cell detectors have been investigated. These detectors can determine the number of ions reaching the sample. Central to the thesis is their fabrication and characterization. READ MORE

  4. 12. Eurasian Arctic Tectonics: Geology of Severnaya Zemlya (North Kara Terrane) and Relationships to the Timanide Margin of Baltica

    Author : Henning Lorenz; David G. Gee; Robert Scott; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Arctic; Severnaya Zemlya; North Kara Terrane; Baltica; bedrock; geology; tectonics; Timanides; Caledonides; Geovetenskap; Earth sciences; Geovetenskap;

    Abstract : The North Kara Terrane (NKT), with Severnaya Zemlya as its main outcrop area, constitutes the Palaeozoic and older rocks of the northern part of the Kara Shelf. Potential field data suggest a continuation into the eastern Barents Shelf. READ MORE

  5. 13. Tectonic evolution of NW Svalbard

    Author : Carl Pettersson; Stockholms universitet; []
    Keywords : Svalbard; Migmatization; Zircon; Provenance;

    Abstract : The Neoproterozoic is a remarkable era in Earth’s history with dramatic variations in climate and biota, possibly resulting in global glaciations events (eg. “snowball earth”, Kirschvink, 1992) and the first appearance of metazoans (Conway Morris, 1993). READ MORE

  6. 14. Early Palaeozoic jawed polychaetes with focus on polychaetaspids and ramphoprionids from the Silurian of Gotland, Sweden

    Author : Mats Eriksson; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysisk geografi; Geologi; physical geography; Geology; chemistry; palaeobiogeography; palaeoecology; taxonomy; apparatus reconstructions; Silurian; Recent; Ordovician; early Palaeozoic; scolecodonts; Annelida; polychaeta;

    Abstract : Jawed polychaete annelid worms were abundant and diverse in the early Palaeozoic seas and their jaws (scolecodonts) are common microfossils in sedimentary rocks of that age. Despite their abundance, relatively little work has been focused on these fossils. READ MORE
