Popular Abstract in Swedish För att lungorna ska utvecklas normalt hos ett däggdjursfoster, måste lungorna vara vätskefyllda. Det har länge varit kännt att denna vätska produceras av lungorna själva, genom s k klorid-sekretion. Vid födelsen måste det nyfödda fostret börja andas och därför är det ytterst viktigt att lungorna snabbt töms på vätskan som fanns där under fosterutvecklingen. Detta sker Alveolar fluid clearance is driven by active absorption of Na+ across the alveolar epithelium. Development and hormonal regulation of alveolar fluid clearance over 1 hour was studied by instillation of a protein-containing, isosmolar fluid into lungs of fetal, newborn, and adult guinea pigs. After 1 hour, a sample of remaining alveolar fluid was collected and the change in protein concentration wa

Popular Abstract in Swedish För att kunna förstå och bedöma exponeringen av kemikalier i miljön, i det här fallet PolyBromeradeDiphenylEtrar (PBDEer), behövs kunskap om källor och flöden från teknosfären till ekosystemen. PBDEer är bromerade flamskyddsmedel som bl a sätts till olika plastmaterial i elektronikanvändning för att förhindra brand. Det används globalt i miljontals kilo och presenteras I have studied the sources, long range transport, and rates of flow of polybrominated diphenyl ethers (PBDEs), from the technosphere to the Baltic ecosystems. PBDEs are mainly used in polymers, which are applied in electrical equipment to prevent overheating or flashover and are produced in large quantities. PBDEs have become widely spread in the environment, where they are able to accumulate in b

Popular Abstract in Swedish Benskörhet (osteoporos) är en sjukdom som karaktäriseras av minskad mängd benmassa och försämrad benkvalitet. Benskörhet leder till en ökad risk för frakturer. Förekomsten av benskörhet har fördubblats under de senaste decennierna. Upp till en tiondel av alla män och en fjärdedel av alla kvinnor lider av sjukdomen. Ökningen av benskörhet i samhället kan delvis förklarasThe aim of this thesis was to evaluate long-term changes in bone mass and skeletal structure in the forearm in the peri- and postmenopausal period. 156 premenopausal women, at baseline aged 48 years, not taking medications and without disease processes known to interfere with bone metabolism, were followed through menopause by measurements of bone mass and skeletal structure at the cortical site o

The availability and exchange of required packaging logistics information is critical to achieve an efficient, effective and responsive retail supply chain. The use of well defined packaging-related information that is available for all actors in the supp1y chain also facilitate an integrated and supply chain oriented packaging development. The objective of this paper is to investigate and describ

The aim of this book is to improve our understanding of creative knowledge environments. The various chapters analyse creative and innovate activities as carried out by individuals, groups and organisations. The book’s focus is on identifying and understanding the factors relating to the working environment that are conducive to human creativity and innovation. The editing of the book has been a c

This study investigates volatility spillovers to electric power fromlarge exogenous shocks in the prices of gas, coal, and carbon emissionallowances in the German energy market. Our sample ranges from 2008 to 2016and covers periods of different market conditions. We use a general VAR-BEKKmodel and the volatility impulse response function methodology to analyze andevaluate the spillover effects. Sp

Background The Ho: YAG laser is used extensively in orthopedic surgery. It offers a minimally invasive method of ablating tissue with precision. Previous studies have explored the effects of laser use on temperature during experimental foraminoplasty. To date, there has been limited work on the effects of thermal stress on cells in this context. Material and methods Cells were exposed either to h

14-3-3 proteins comprise a family of highly conserved proteins. 14-3-3 proteins have been found in all organisms examined except for members of the prokaryotic kingdom. 14-3-3s are involved in numerous processes in the cell and they typically bind to phosphorylated motifs in other proteins and regulate their activities. In plants, 14-3-3 proteins are recognized as key regulators of primary metabo

This current issue of CyberOrient brings together academics active at Scandinavian universities focusing on hip-hop from different aspects and fields. From different perspectives the authors seek to make sense of the impact, functions and dynamics of Middle Eastern and/or Islamic representations in hip-hop music online, both within and beyond the Middle East.

Popular Abstract in Swedish Jungfru Marie nycklar och skogsnycklar: systematik, evolution och invandringshistoria Jungfru Marie nycklar (ssp. maculata) och skogsnycklar (ssp. fuchsii) bildar tillsammans ett mångformigt och vittspritt artkomplex inom det eurasiska orkidésläktet Dactylorhiza. I min avhandling har jag kommit fram till flera allmänna och biologiskt viktiga slutsatser rörande artbildnThe aim of this thesis was to investigate and describe different aspects of variation in the Dactylorhiza maculata complex and to relate the variation patterns to underlying biological processes such as Quaternary migration history, hybridization and polyploid evolution. The variation patterns were analysed at various geographic levels using molecular markers (plastid DNA and ITS of nrDNA), cytolo

Popular Abstract in Swedish Principen för biologisk vattenreningsteknik är att mikroorganismer används för att bryta ner olika typer av föroreningar. Då det finns en stor mängd olika sorters mikroorganismer, kan flera typer av nedbrytningsmekanismer och processutformningar utnyttjas för olika krav och syften. Nackdelen med biologisk vattenreningsteknik är dock att den är känslig för störningar ochThe aim of the thesis was to investigate how different abiotic and biotic parameters may affect microorganisms and the process performance in various biological wastewater treatment systems. The type of carbon source in the influent wastewater may have a profound effect on the composition and the activity of denitrifying activated sludge bacteria in nutrient removal. Of four investigated carbon s

The substitution in varying amounts of strontium (Sr) for calcium in the alpha tricalcium phosphate (α TCP) structure was investigated. The effects on the reactivity towards the formation of hydroxypalatite on hydration were also studied. The prepared α-TCP and the fully hydrated α-TCP powders were characterized by means of X-ray diffraction and the CuKα1 radiation. It was found that the alpha for

Popular Abstract in Swedish Avhandlingen bygger på en studie av halter av stabila organiska miljögifter (PCB) i luften, i nederbörd och i jord. Studien har utförts vid 11 provtagnings platser i Skåne. Vidare behandlas global transport av stabila miljögifter i avhandlingen.In these thesis I have studied the spatial and temporal variations of PCBs in the atmosphere and in precipitation in southern Sweden. Further, soil-air exchange processes of PCBs were investigated. Finally, the long-range transport of PCBs and DDT was studied in the Baltic Sea region and in a tropical vs. a temporal region. On the regional scale there were significant differences in PCB concentrat

Popular Abstract in Swedish Grundämnena tyngre än järns ursprung är en vital fråga inom historien on och evolutionen av vår galax. Grundämnena upp till och med järngruppen produceras huvudsakligen genom fusion inne i stjärnor som ger dem deras energi. De ännu tyngre grundämnena produceras istället huvudsakligen genom neutroninfångningsprocesser: Den svaga s-processen, huvud-s-processen och r-proceThe pedigree of the elements heavier than iron is a vital question in the history and evolution of our galaxy. The elements up to and including those of the iron group are produced mainly through fusion processes within stars, giving the stars their energy. The even heavier elements are instead mainly produced through neutron capture processes: weak s-process, main s-process and r-process. The wea

This paper explores the linguistic encoding of placement and removal events in Swedish. Drawing on elicited spoken data, it provides a unified approach to caused motion descriptions. The results show uniform syntactic behaviour of placement and removal descriptions and a consistent asymmetry between placement and removal in the semantic specificity of verbs. The results also reveal three further s
