  1. 1. Geological development of the East African coastal basin of Tanzania

    Författare :Samson Mpanda; Ole Veibaeck; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine Geology; seismic methods; seismic stratigraphy; multichannel seismic recordings; tectonic development; Karoo; Mesozoic; Tertiary; East Africa; Tanzania; Earth sciences; Geovetenskap; allmän och historisk geologi; General and Historical Geology;

    Sammanfattning : The East African coastal basin of Tanzania, which is characterised by an extensional tectonic style, is located along the passive continental margin of the western Indian Ocean. The present study is concerned with the Mafia Island and the Mafia Channel which together form a subbasin within the north-south elongated coastal sedimentary basin of Tanzania. LÄS MER

  2. 2. Stuttering in young females and males

    Författare :Ineke Samson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Stuttering is a relatively common speech disorder and most people have met someone who stutters. Symptoms of stuttering are repetitions, prolongations and blocks that stop the natural flow of speech. LÄS MER

  3. 3. Development of catalytic enantioselective C-C bond-forming and cascade transformations by merging homogeneous or heterogeneous transition metal catalysis with asymmetric aminocatalysis

    Författare :Samson Afewerki; Armando Córdova; MICHELANGELO GRUTTADAURIA; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; asymmetric catalysis; transition metals; aldehydes; heterogeneous catalysis; amino acid; organocatalysis; α-allylation; β-alkylation; dynamic transformations; polysubstituted; carbocycles; spirocyclic oxindoles; all-carbon quaternary stereocenters;

    Sammanfattning : Chiral molecules play a central role in our daily life and in nature, for instance the different enantiomers or diastereomers of a chiral molecule may show completely different biological activity. For this reason, it is a vital goal for synthetic chemists to design selective and efficient methodologies that allow the synthesis of the desired enantiomer. LÄS MER

  4. 4. Double Pion Production in the dd to αππ reaction

    Författare :Samson Keleta; Pia Thörngren Engblom; Bo Höistad; Hans Ströher; Uppsala universitet; []
    Nyckelord :Nuclear physics; ABC effect; double pion; Kärnfysik; Nuclear Physics; kärnfysik;

    Sammanfattning : The reaction dd → 4Heππ has been measured exclusively for the first time. The measurements were performed at Td = 712 MeV and Td = 1029 MeV, with the WASA detector assembly at CELSIUS (Uppsala-Sweden). The aim was to investigate a long standing puzzle, the so called ABC effect. LÄS MER

  5. 5. Climate Policy and Financial Markets

    Författare :Samson Mukanjari; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; burden sharing; climate policy; commodity futures; distribution; environmental deregulation; Environmental Protection Agency; EPA; equity; event study; fairness; impulse-indicator saturation; international climate negotiations; Paris Agreement; Trump;

    Sammanfattning : Climate change represents a serious, as-yet-unresolved global commons problem. After decades of international climate negotiations, 195 nations adopted the Paris climate agreement in December 2015. The subsequent election of Donald Trump as US president in 2016 was seen as a setback for climate policy. LÄS MER
