  2. 1. The braincase of Youngolepis, a Lower Devonian crossopterygian from Yunnan, south-western China

    Author : Mee-mann Chang; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fiskar; Paleozoologi;

    Abstract : The endocranium and skull roof of Youngolepis, a Lower Devonian crossopterygian from south-western China, is described based on some 40 specimens of which one was investigated by serial grinding. In cranial structure Youngolepis Chang et Yu, 1981, shows affinity to Powichthys Jessen, 1975, from the Lower Devonian of the Canadian Arctic. READ MORE

  4. 2. Plasma and Dust around Icy Moon Enceladus and Comet 67P/Churyumov-Gerasimenko

    Author : Ilka. A. D. Engelhardt; Anders Eriksson; Ingrid Mann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : Saturn's moon Enceladus and comet 67P/Churyumov-Gerasimenko both are examples of icy solar system objects from which gas and dust flow into space. At both bodies, the gas becomes partly ionized and the dust grains get charged. READ MORE

  5. 3. Multi-point Measurements of Ultra Low Frequency Waves in the Terrestrial Magnetosphere

    Author : Tommy Eriksson; Lars Blomberg; Ian Mann; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space physics; Rymdfysik;

    Abstract : Waves in the mHz frequency range are prominent features of the terrestrial magnetosphere. In this frequency range the waves have wavelengths comparable to the lengths of the geomagnetic field lines. The waves are then standing waves along closed field lines with endpoints in the southern and northern ionosphere. READ MORE

  7. 5. Morphometric analysis of Cambrian fossils and its evolutionary significance

    Author : Illiam Jackson; Graham Budd; Jorijntje Henderiks; Richard Mann; Nigel Hughes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extended Evolutionary Synthesis; phenotypic plasticity; genetic assimilation; phenotypic accommodation; Agnostus pisiformis; Mackinnonia; elliptical fourier analysis; species concept;

    Abstract : The Extended Evolutionary Synthesis (EES) is currently emerging as a theoretical alternative to the Modern Synthesis (MS) in which to frame evolutionary observations and interpretations. These alternative frameworks differ fundamentally in their understanding of the relative roles of the genotype, phenotype, development and environment in evolutionary processes and patterns. READ MORE
