  2. 2. The Alnö alkaline and carbonatitic complex, east central Sweden - a petrogenetic study

    Författare :Jaana Hode Vuorinen; Alasdair Skelton; Ulf Hålenius; Stefan Claesson; Ian Parsons; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; carbonatite; alkaline; Alnö; geochemistry; isotope; Earth sciences; Geovetenskap;

    Sammanfattning : The Alnö complex on the central Swedish east coast is composed of a main composite intrusion (the main intrusion) and four smaller satellite intrusions (Söråker, Sälskär, Långharsholmen and Båräng) distributed around the main intrusion on Alnö Island and on the mainland north of the island. The major rock types exposed within the complex are melilitolite, pyroxenite, ijolite series (melteigite-ijolite-urtite), nepheline syenite, carbonatite and alnöite dykes. LÄS MER

  3. 3. A clinical positron emission tomography facility : 2-¹⁸FDG studies : development and results

    Författare :Tomas G Ohlsson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; head and neck cancer; monitoring therapy effect; quantification; normalization; 511 keV SPECT; rotating PET scanner; 2-[18-F]FDG; isotope production; 18-F; PET; positron emission tomography; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; Fysicumarkivet A:1996:Ohlsson;

    Sammanfattning : Positron emission tomography (PET) is a tracer technique used for quantitative in vivo studies of physiological and biochemical processes. Because of the use of positron-emitting radionuclides such as 11-C, 13-N, 15-O and 18-F, which are isotopes of the biologically ubiquitous elements, it is possible to label radiopharmaceuticals which trace biochemical processes precisely.

  4. 4. Isotope-based reconstruction of the biogeochemical Si cycle : Implications for climate change and human perturbation

    Författare :Xiaole Sun; Carl-Magnus Mörth; Christoph Humborg; Per Andersson; Brian Fry; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; diatoms; biogenic silica BSi ; dissolved Si DSi ; Si isotope fractionation; the Baltic Sea; geokemi; Geochemistry;

    Sammanfattning : The global silicon (Si) cycle is of fundamental importance for the global carbon cycle. Diatom growth in the oceans is a major sequestration pathway for carbon on a global scale (often referred to as the biological pump). LÄS MER

  5. 5. High-throughput protein analysis using mass spectrometry-based methods

    Författare :Tove Boström; Sophia Hober; Thomas Laurell; Ole N. Jensen; KTH; []
    Nyckelord :Proteomics; mass spectrometry; affinity proteomics; immunoenrichment; immunoprecipitation; IMAC; screening; protein production; protein purification; ISET; quantification; SILAC; stable isotope standard; antibody validation; Bioteknologi; Biotechnology;

    Sammanfattning : In the field of proteomics, proteins are analyzed and quantified in high numbers. Protein analysis is of great importance and can for example generate information regarding protein function and involvement in disease. Different strategies for protein analysis and quan- tification have emerged, suitable for different applications. LÄS MER
