  2. 1. Aquatic vegetation in coastal ecosystems : The role of biotic interactions and environmental change for ecosystem functions and resilience in the Baltic Sea

    Author : Åsa Austin; Johan S. Eklöf; Joakim P. Hansen; Serena Donadi; Matthew E. S. Bracken; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecosystem functions; ecosystem multifunctionality; water clarity; fish recruitment; functional traits; feedbacks; biotic interactions; competition; facilitation; foundation species; seagrass; macrophytes; lagoons; brackish water; Baltic Sea; marin ekologi; Marine Ecology;

    Abstract : Coastal ecosystems are among the most productive on Earth but subjected to many human pressures. In shallow coastal areas, aquatic vegetation constitutes foundation species that sustain secondary production and act as a nutrient filter, which may buffer human impacts. READ MORE

  4. 2. Modelling and control of turbulent and transitional flows

    Author : Pierluigi Morra; Dan S. Henningson; Ardeshir Hanifi; André V. G. Cavalieri; Shervin Bagheri; Aimee S. Morgans; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reduced order modeling; flow control; resolvent analysis; transi- tional boundary layer; turbulent boundary layer; drag reduction; high-fidelity wall-turbulence modelling; modellreduktion; strömningskontroll; resolvent analys; laminär- turbulent omslag; turbulent gränsskikt; motståndsminskning; väggturbulens modellering; Engineering Mechanics; Teknisk mekanik;

    Abstract : The dynamics of fluid motion can accurately be described by the Navier– Stokes equations. Manipulating these equations to reduce their complexity but preserving their main characteristics has always been a key research activity in the field of fluid mechanics. READ MORE

  5. 3. The Role of Proline Catabolism in Candida albicans Pathogenesis

    Author : Fitz Gerald S. Silao; Per O. Ljungdahl; Joachim Morschhäuser; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Candida albicans; proline metabolism; ATP; P5C; virulence; macrophage; hyphae; filamentation; Ras1 cAMP PKA; mitochondria; Proline dehydrogenase; P5C dehydrogenase; reactive oxygen species; Proline-P5C cycle; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Candida albicans is an opportunistic fungal pathogen that has evolved in close association with human hosts. Pathogenicity is linked to an array of virulence characteristics expressed in response to environmental cues and that reflect the requirement to take up and metabolize nutrients available in the host.

  6. 4. Determining the role of guanylate-binding proteins for host defense against Francisella tularensis

    Author : Nasibeh Mohammadi; Anders Sjöstedt; Wolfgang P. Schröder; Anetta S. Härtlova; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella tularensis; Guanylate-binding proteins; bone marrow-derived macrophages; IFN-γ activation; cytokine patterns; inflammasome pathways; co-infection; mouse co-culture model; Biochemistry; biokemi; immunologi; Immunology; mikrobiologi; Microbiology; molekylärbiologi; Molecular Biology; Infectious Diseases; infektionssjukdomar;

    Abstract : Francisella tularensis is a highly virulent, intracellular bacterium and the causative agent of the human disease tularemia. This is a zoonotic, often vector-borne disease. Due to its intracellular nature, F. READ MORE

  7. 5. Polyploid Phylogenetics in Plants: Insights on non-model organisms in Fabaceae and Malvaceae

    Author : Jonna S. Eriksson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Diploidization; genome duplication; haplotypes; Hibisceae; Hibiscus; homoeologues; high-throughput sequencing; Pavonia; Malvaceae; polyploidization;

    Abstract : Genome duplication is a common phenomenon in angiosperms and advances in sequencing technologies and bioinformatics is now revealing its prevalence and significance. In a polyploidization event all genes in a genome are doubled. READ MORE
