Effects of toxin-producing phytoplankton on copepods: feeding, reproduction and implications to the fate of toxins

Popular Abstract in Swedish Effekter av giftiga växtplankton på copepoder Vad är växtplankton och copepoder? Växtplankton eller mikroalger som de också kalla's är de dominerande växterna i havet. Det finn's många olika typer av växtplankton och de är alla mycket små (dera's storlek är mellan ett par till några hundra tusendelar av en millimeter). Växtplanktonen använder ljusenergin från solen ocPhytoplankton growth and loss rates are governed by several factors and in many cases, when growth control fails, algal blooms are established. Such blooms can be formed by different phytoplankton species and some of them have harmful impacts on marine ecosystems. One of these negative impacts by some bloom-forming phytoplankton is the ability to produce toxic or inhibitory compounds with broad ef

Functional, structural and evolutionary studies on a family of bacterial surface proteins

Popular Abstract in Swedish Hos människan lever en rad mikroorganismer som tillsammans utgör normalfloran. Normalfloran återfinns på alla kroppsytor, det vill säga huden och slemhinnorna i munnen, svalget, magsäcken, tunn- och tjocktarmen, vagina och urinrörsmynningen. Samspelet mellan människokroppen och mikroorganismerna utsätts dagligen för påfrestningar. En sådan naturlig påfrestning är de sjuThis thesis is concerned with a family of bacterial surface proteins expressed by different strains of the anaerobic Gram-positive, commensal and human pathogen Peptostreptococcus magnus. These proteins have been studied with respect to their role in virulence, function, structure, and evolution. Strains isolated from patients with vaginosis have previously been shown to be associated with express

Nordic universities- do they have any entrepreneurial objectives and strategies?

This paper reports on a survey of the 20 largest Nordic universities, 12 Humboldtian type universities and 8 technical universities, and their espoused objectives and strategies regarding their entrepreneurial and innovation role related to regional and national economic development. The study is based on archival data; public documents issued by each university and higher education authorities. T

Numerical Study of Dispersed Two-phase Flows

This thesis considers the numerical study of dispersed two-phase flows.Numerical simulations have been done to investigate the particle trasportation/dispersion effect in turbulent two-phase flows. Both turbulent bubble/water flows and turbulent particle/air flows are studied. Eulerian/Eulerian approach and Eulerian/Lagrangian approachs were both used in the studies. In the Eulerian-Eulerian appro
