  1. 6. Evolutionary genomics in Corvids : – From single nucleotides to structural variants

    Författare :Matthias H. Weissensteiner; Jochen B.W. Wolf; Manfred Grabherr; Kateryna M. Makova; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; evolutionary genetics; genomics; population genetics; selection; recombination; chromosomal features; colouration; insertion; deletion; inversion; crow; tandem repeat; transposable element; gene expression;

    Sammanfattning : Heritable genetic variation is the raw material of evolution and can occur in many different forms, from altering single nucleotides to rearranging stretches of millions at once. DNA mutations that result in phenotypic differences are the basis upon which natural selection can act, leading to a shift of the frequency of those mutations. LÄS MER

  3. 7. Ethno-Politics : The Consequences of Ethnic Discrimination for Latino Ethnic Identity Orientation and Ethno-Mobilization

    Författare :Azril Bacal Roij; Hedvig Ekerwald; Manuela Boatcă; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; structural racial ethnic inequality; cultural racism; color line; ethnic discrimination; ethnic identity orientation; ethno-politics; citizenship; national identity; Latino Movement; racialization; experiential research; Sociologi; Sociology; Sociologi; Sociology; Sociologi; Sociology; Sociologi; Sociology;

    Sammanfattning : This compilation thesis is a study of Latino migrants and Latino minority members, mainly in USA, and also in Sweden. The three theoretical and the two empirical studies cover a long period and are grounded in ethnicity as an established study field. LÄS MER

  4. 8. Structural and magnetic disorder in crystalline materials : a first principles study

    Författare :Davide Gambino; Björn Alling; Pavel Korzhavyi; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Disorder in crystalline materials can take different forms and originate from different sources. In particular, temperature introduces disorder in any kind of material. LÄS MER

  5. 9. Prenatal diagnosis of structural malformations and chromosome anomalies : Detection, influence of Body Mass Index and ways to improve screening

    Författare :Eric Hildebrand; Marie Blomberg; Tomas Gottvall; Jan Brynhildsen; Ove Axelsson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Introduction: Prenatal diagnosis of structural malformations and chromosome anomalies is possible in the presence of an effective screening with ultrasound during pregnancy. The continuous evolution of the ultrasound equipment facilitates the examination. LÄS MER

  7. 10. Seeing the invisible: Evolution of wing interference patterns in Hymenoptera, and their application in taxonomy

    Författare :Ekaterina Shevtsova; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chalcidoidea; parasitic wasps; structural colors; visual signaling; cryptic species; sexual dimorphism; wing membrane thickness; wing micro-morphology; wing cuticle ultrastructure;

    Sammanfattning : The remarkably thin transparent wing membranes in tiny wasps may appear to have a simple structural design, but hide a largely unexplored complex of micro-morphological features that serve aerodynamics and may also function in visual signaling. I found that when such small transparent wings are viewed against a dark background they display vivid structural color patterns due to thin film interference, and named them Wing Interference Patterns (WIPs).
