  2. 16. Environmental effects on pollen performance:potential consequences on gene flow

    Author : Margaret Mollel; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant ecology; siring ability; risk assessment; pollen germination; pollen tube growth rate; Nicotiana alata; morphological markers; Cucumis sativus; Genetically modified crops hybridisation; Växtekologi;

    Abstract : This thesis illustrates the effects of environmental factors on pollen performance and its importance on gene flow. Pollen competitive ability between the wild and cultivated species of four genera belonging to Cucurbitaceae family was compared to evaluate the evolutionary potential for selection on pollen tube growth rate.

  4. 17. Airway maturation in Drosophila

    Author : Katarína Tiklová; Christos Samakovlis; Richard Fehon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; utvecklingsbiologi; Developmental Biology;

    Abstract : Tubes are a fundamental unit of organ design. Most of our major organs like the lung, kidney and vasculature are composed primarily of tubes. To identify fundamental biological principles of tubular organ formation we used the respiratory organ of Drosophila melanogaster, the trachea.This work dissects embryonic trachea maturation.

  5. 18. Embryonic ecdysone-induced gene expression and progression of organ morphogenesis

    Author : Tina Mitra Chavoshi Alizadeh; Göteborgs universitet; []
    Keywords : Drosophila; trachea; hindgut; tubulogenesis; luminal matrix; ecdysteroid; EcR:Usp; dorsal closure;

    Abstract : The formation of an epithelial organ requires a set of organ-specific gene programs that instruct parallel and successive developmental events. Still, it is unclear what are the core regulatory programs and how such programs are timely coordinated within the organ. READ MORE

  6. 19. Fluorescent Probes and Protein Misfolding: Methods and Applications

    Author : Irem Nasir; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein misfolding; fluorophores; filter-trap; site-specific fluorophore labeling; amyloid-beta; microscopic rate constants; solvatochromic probes; alpha-synuclein; lipid vesicles; nanoparticles; protein adsorption;

    Abstract : Protein misfolding is a frequently occurring event in living cells and without the quality control, the consequences are disasterous. In this thesis, we studied protein misfolding in vitro by employing a variety of fluorophores, to either detect the highly ordered aggregates of intrinsically disordered proteins/peptides or slight misfolding of a natively folded protein.

  7. 20. Experimental investigation of a Kaplan runner under steady-state and transient operations

    Author : Kaveh Amiri; Gabriel Dan Ciocan; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Hydropower is a key part in electricity production nowadays. Hydropower electricity production rose to 3579.5 TWh in 2013, ranked as the second source of electricity production in the world after fossil fuels. It is the principle source of renewable electricity production, producing 16. READ MORE
