  1. 1. A globolo gems. Late Etrusco-Italic scarab intaglios

    Författare :Ulf Hansson; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Etruscan; Etrusco-Italic; a globolo; scarab; engraved gem; glyptic; engraving technique; archaeogemmology; archaeology; find context; typology; iconography; standardisation; serial production; consumption; auto-representation;

    Sammanfattning : The study treats a class of engraved scarab gems commonly known by the name of a globolo, produced in Central Italy in the Late Classical to Early Hellenistic periods. The point of departure is a newly developed database of all known specimens, which amount to 1,470, covering a wide range of information categories, which have guided the structure of the presentation.

  3. 2. Neural Interfaces to the Odour World of Scarab Beetles

    Författare :Mattias Larsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Intra; Antennal lobe; CNS; Attraction; Olfactometer; Behaviour; Mass spectrometry; Gas chromatography; Electrophysiology; Single sensillum; Receptor neuron; Plant volatile; Sex pheromone; Neuroethology; Odour detection; Olfaction; Coleoptera; Scarabaeidae; Entomology; plant parasitology; Entomologi; växtparasitologi; Environmental chemistry; Miljökemi;

    Sammanfattning : Antennal detection and central nervous integration of behaviourally relevant odours in scarab beetles (Coleoptera: Scarabaeidae) was investigated, using the two Japanese scarabs Anomala cuprea and Phyllopertha diversa (Rutelinae), and the Central African fruit chafer Pachnoda marginata (Cetoniinae) as model species.

  4. 3. Mueller matrix ellipsometry studies of nanostructured materials

    Författare :Roger Magnusson; Hans Arwin; Kenneth Järrendahl; Morten Kildemo; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Materials can be tailored on the nano-scale to show properties that cannot be found in bulk materials. Often these properties reveal themselves when electromagnetic radiation, e.g. light, interacts with the material. LÄS MER

  5. 4. Optical and Structural Characterization of Natural Nanostructures

    Författare :Lía Fernández del Río; Kenneth Järrendahl; Hans Arwin; Arturo Mendoza-Galván; Dimitri Deheyn; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The spectacular biodiversity of our planet is the result of millions of years of evolution. Over this time animals and plants have evolved and adapted to different environments, developing specific behavioral and physical adaptations to increase their chances of survival. LÄS MER

  7. 5. Design and Characterization of Functional Structures for Electromagnetic Waves

    Författare :Andreas Ericsson; Teoretisk elektroteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electromagnetic scattering; functional structure; circular polarization selective structure; reflector antenna; electromagnetic absorber; radar cross section; compressive sensing; triaxial weave; homogenization; physical optics;

    Sammanfattning : This dissertation deals with design and characterization of functional structures for scattering of electromagnetic waves. An abundance of these structures can be found in nature, such as the structural coloration in the feathers of a peacock, the scales of butterflies and the shell of scarab beetles. LÄS MER
