  2. 16. Gall induction in gall wasps (Cynipidae s. lat.) : Insights from comparative genomics

    Author : Erik Gobbo; Fredrik Ronquist; Scott Egan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gall induction; comparative genomics; evolution; selection analysis; microbiome; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : Cynipidae are a family of wasps (Hymenoptera), whose larval stages develop inside plant galls, that is, abnormal plant structures formed in response to the presence of foreign organisms. Most cynipids are gall inducers and are often capable of notable levels of host manipulation. READ MORE

  4. 17. Genetic and environmental aspects of symptomatic gallstone disease

    Author : Despina S Katsika; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Gallstone; Swedish Twin Registry; monozygotic; dizygotic; structural equation modeling; body mass index; alcohol; tobacco; ABCG8 D19 H; lith genes; association study;

    Abstract : Gallstone disease (GD) represents a major healthcare problem. Gallstones are likely to result from a complex interaction of the environment and the effects of multiple undetermined genes. READ MORE

  5. 18. Radiation induced losses in Ytterbium doped laser materials

    Author : Sara Rydberg; Magnus Engholm; Hans-Erik Nilsson; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this work, two types of ytterbium (Yb) doped laser materials are studied, crys-talline Yb:YAG and amorphous Yb/Al silica in both preform and fiber. Yb is suitableas a laser ion because of its simple energy level structure and low quantum defect. READ MORE

  6. 19. Metabolic responses ofPseudomonas stutzeriandEscherichia colisubjected to starvation and surplus of carbon/energy substrates in bioreactors

    Author : Bo Xu; KTH; []
    Keywords : ;

    Abstract : Transient nitrite accumulation during anaerobicdenitrification is a widespread phenomenon for manydenitrifying bacteria includingPseudomonasstutzeri. Nitrate starvation caused the degradation ofthe second denitrifying enzyme nitrite reductase (NiR) inP.stutzeri. READ MORE

  7. 20. Phylogenetic Studies in the Gentianales – Approaches at Different Taxonomic Levels
