Temporal trends of Polybrominated diphenyl ethers (PBDE) and Hexabromocyclododecane (HBCDD) in Swedish Otter (Lutra lutra) and Grey Seals (Halichoerus grypus)

Polybromerade difenyletrar (PBDE) och hexabromcyklododekan (HBCDD) är bromerade flamskyddsmedel som har använts i stor utstäckning i olika produkter under lång tid. Dessa föreningar är svårnedbrytbara och fettlösliga vilket innebär att de kan lagras länge i fettvävnaden. Både kemin och egenskaperna hos PBDE og HBCDD liknar det kända miljögiftet PCB, vilket gör at det är intressant att se närmare pPolybrominated diphenyl ethers (PBDE) and hexabromocyclododecane (HBCDD) are brominated flame retardants. These compounds are lipophilic, persistent and have been shown to bioaccumulate. The Baltic grey seal (Halichoerus grypus) and the Eurasian otter (Lutra lutra) are top predators and especially exposed to high levels of lipophilic pollutant in their diet due to biomagnification. In the current

Going beyond archetypes: a story about inspiration, limits, and communication

Archetypes, as universal patterns or prototypes, are deeply ingrained in the collective consciousness and shape our expectations about the appearance, function, and meaning of objects. However, as products and their contexts change, it becomes necessary to find ways to break away from existing archetypal images. This thesis explores the development of archetypes, the boundaries of object categori

Allelopathic Interactions between Cyanobacteria and Dinoflagellates - Rapid Naiadinium polonicum decline in co-culture with Microcystis sp.

The frequency of harmful algal blooms is increasing steadily, and every summer there are phycotoxins compromising the quality of freshwater ecosystems. Although this is of rising concern, the mechanisms behind harmful algal blooms are not yet fully understood. Cyanobacteria are the usual culprits, while freshwater dinoflagellates have generally been considered non-toxic, though toxic blooms of fre

Investigating intrinsically derived IgA responses in the intestine of young mice in steady-state and infected conditions

Hålla tarmbakterier i schack hos unga möss Efter födseln exponeras ett spädbarn för den yttre miljön för första gången. Detta innebär exponering för ett stort antal bakterier och virus. Spädbarn är mer benägna att bli infekterade av bakterier och virus än vuxna. Hos vuxna kan antikroppen Immunoglobulin A (IgA) hjälpa till att hålla bakterier och virus i schack genom att omsluta dem och agera som The period after birth, when an infant is initially exposed to vast amounts of environmental and microbial antigens, sets the stage for proper immune system development ensuing lifelong immunity. Simultaneous to this first-time exposure, the nursing mother provides immune protection via antibodies in the breast milk. Secretory Immunoglobulin A, as provided by the mother or produced intrinsically i

Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

Tillgång och Effektfrågan – Biogasens Roll i det Gröna Norrbotten Allt fler nyfikna ögon riktas mot Norrland i takt med att den nordligaste landsänden ångar på framåt i utvecklingen mot fossilfria industrier; kommande år planeras miljardinvesteringar i fossilfria tekniker i region Norrbotten, en satsning som kallas den gröna omställningen. Men för att kunna förse etableringarna och samhället medGreat investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the produc

THRIVE - with heritage to sustainability

The historic urban area of Lisbon emerged during the Middle Ages and was the origin of the development of a rather small neighbourhood, Mouraria. Not only did it count as the centre of the capital, but because of Lisbon being the metropolis of the Portuguese empire, Mouraria is now home to a diverse group of people, whose culture influences its special characteristics to this day. Its medieval str

Deposition av Black carbon i sjöar efter den stora skogsbranden i Västmanland 2014

Vem tycker inte det är mysigt att sitta framför sin kamin, eldstad eller grill? Något som är gemensamt är att samtliga innefattar eldning av biomassa. Eldning av biomassa gör vi av många anledningar. Det kan vara allt från trivseleldning till uppvärmning och elförsörjning. Eldning för många kan vara att få möjligheten att laga mat, varför man eldar ser väldigt annorlunda ut i olika delar av världeBlack carbon (BC) is produced during incomplete combustion of Biomass and fossil fuels. BC and other carbonaceous pollutants have characteristics that affect the climate, environment, and human health. Historically, BC emissions have been measured and monitored in the atmosphere, and BC emissions to the air are quite well documented. Deposition in water and sediments has been less studied but is i
