Popular Abstract in Swedish Alla levande organismer består av celler som tillsammans med molekyler generellt kallade extracellulär matrix bildar en vävnad. Celler innehåller fyra huvudgrupper av byggstenar: socker, fettsyror, aminosyror och nukleotider, vilka i tur och ordning bildar kolhydrater, fetter, proteiner och nukleinsyror. I vävnaderna pågår en ständig omsättning av byggstenarna och molekThis thesis describes structural and functional studies of alpha-1-microglobulin (a1m), a 26 kDa plasma and tissue protein that is evolutionarily well-conserved and belongs to the lipocalin superfamily. The lipocalins are polypeptides of 160-190-amino acids that are folded into an 8-stranded beta-barrel forming a pocket with a hydrophobic interior. a1m carries heterogeneous yellow-brown chromophor

Popular Abstract in Swedish Intresset för förnybara bränslen har ökat stadigt under de senaste åren. Att byta ut fossila mot förnybara bränslen kan minska utsläppen av växthusgaser till atmosfären och därmed minska klimatpåverkan av dessa men även minska vårt beroende av olja. Biobränslen som t.ex. etanol, biodiesel eller biogas, räknas till förnybara bränslen eftersom de inte bidrar till en ackumReplacing fossil fuels by biofuels such as ethanol is considered a promising alternative to reduce greenhouse gas (GHG) emissions and mitigate climate change. Biofuels produced from lignocellulosic biomass, so-called second generation biofuels, result in decreased GHG emissions and limit competition with food and animal feed production. Interest in producing ethanol from lignocellulosic biomass ha

DNA-dependent protein kinase (DNA-PK) is a holoenzyme consisting of a regulatory subunit, the heterodimeric Ku70/86, and a catalytic subunit known as DNA-dependent protein kinase catalytic subunit (DNA-PKcs). DNA-PK takes part in a number of cellular functions including growth control, immunoglobulin gene rearrangement and DNA repair. The Ku86 subunit of DNA-PK has been reported to exist in human

Popular Abstract in Swedish Traditionellt har olika aspekter av ett ekosystem studerats var för sig inom olika ekologiska discipliner såsom växtfysiologi, forskning om hur organismer interagerar med varandra och forskning om hur ekosystem som helhet beter sig. Denna avhandling innehåller exempel på att simulationsmodeller gör det möjligt att undersöka hur de olika processerna samverkar för att forPlant physiology, population dynamics and the structure and functioning of ecosystems are closely interrelated. However, these processes are often investigated independently within different subdisciplines of ecology. Mechanistic models of ecosystem structure and functioning combine representations of processes operating at a range of scales and levels of organisation, providing a tool for the des

Popular Abstract in Swedish ”Practice variation” I den kliniska vardagen ser man ofta slående variationer i handläggningsrutiner mellan läkare och vårdcentraler utan att detta kan förklaras av skillnader i sjuklighet hos patienterna. Dessa oförklarade skillnader benämns ”practice variation” och beror på lokalt förankrade rutiner ofta etablerade sedan länge. De är sällan vetenskapligt underbyggda u

Uppsatsen tar avstamp i den ökning av människor som vill söka asyl i Europa som skett under hösten 2015 och våren 2016 och medlemsstaterna i EU:s åtgärder för att hantera detta. Dessa åtgärder består bland annat av stängda gränser, resande av taggtrådsstängsel, upprättande av gränskontroller och transitzoner och genomföranden av snabba gränsförfaranden. Förfarandena har kritiserats för att strida

År 2013 initierades BEPS-projektet av OECD, vilket syftar till att motverka skatteflykt och erodering av skattebaser. En av projektets åtgärdspunkter (nummer 7) har till ändamål att förändra definitionen av vad som utgör ett fast driftställe enligt OECD:s modellavtal. Den nuvarande definitionen av ett fast driftställe har varit i stort sett oförändrad sedan den infördes i modellavtalet 1963. I taThe OECD initiated the BEPS project in 2013 with the purpose of eliminating tax avoidance and profit shifting. One of the actions in the project aims to change the current definition of permanent establishments in the OECD model convention, especially concerning dependent and independent agents. The current definition of a permanent establishment has, with the exception of minor changes, been in

Under de senaste åren har södra halvklotet och den vidsträckta Södra oceanen fått ökad upp-märksamhet och betydelse inom det vetenskapliga samfundet med avseende på globala klimatförändringar och den globala CO2-cykeln, särskilt vad gäller förhållandena under senaste istidsmaximum (Last Glacial Maximum, LGM) och holocen. Man menar att Västvindbältet på södra halvklotet (Southern Hemisphere WesterlIn recent years, the Southern Hemisphere (SH) and the vast Southern Ocean (SO) have gained awareness and importance within the scientific community in relation to global climate change and the global CO2 cycle, par-ticularly since the Last Glacial Maximum (LGM) and into the Holocene. It is believed that the Southern Hemi-sphere Westerlies (SHW) play a key role in regulating climate change in the m

Artikel 346.1 b FEUF ger medlemsstaterna möjlighet att göra undantag från EU-rätten när en åtgärd är nödvändig för att skydda deras väsentliga säkerhetsintressen och har samband med produktion av eller handel med vapen, ammunition och krigsmateriel. Bestämmelsen har använts för att genomföra försvarsupphandling utanför den ordinarie EU-rättsliga ramen sedan Europeiska gemenskapens bildande, och ärArticle 346(1)(b) TFEU allows Member States to derogate from EU law when a measure is necessary for the protection of the essential interests of their security and is connected with the production of or trade in arms, munitions and war material. The provision has been used to con-duct defence procurement outside the EU legal framework since the formation of the European Community, and remains a re

Terrestrial ectotherms are challenged by variation in both mean and variance of temperature. Phenotypic plasticity (thermal acclimation) might mitigate adverse effects, however, we lack a fundamental understanding of the molecular mechanisms of thermal acclimation and how they are affected by fluctuating temperature. Here we investigated the effect of thermal acclimation in Drosophila melanogaster

The Expansion of Higher Education in the Swedish the Welfare State and the  Reconfiguration of its Professional Workforce   Gunnar Olofsson   The rapid expansion of the Swedish university sector has channelled many students into study programs that lead to employment in new kinds of jobs, occupations and professional groups. There are three main reasons why more and more occupations get their trai

Addressing sustainability concerns in supply chain operations can be a matter of long-term business survival for food retailers. However, regardless of whether it is perceived as a risk or market opportunity, acting across the value chain to address unsustainable production and consumption practices has been a constant challenge. This thesis investigated the sustainable supply chain management (SS

Land cover governs biogeophysical and biogeochemical feedbacks between the land surface and atmosphere. Holocene vegetation-atmosphere interactions are of particular interest, both to understand the climate effects of intensifying human land use and as a possible explanation for the Holocene Conundrum, a widely studied mismatch between simulated and reconstructed temperatures. Progress addressing

Background/Purpose: There has been increasing interest in diet as a factor that may contribute to the development of rheumatoid arthritis (RA). There is limited and somewhat contradictory information on the impact of dairy products in this context. The purpose of this study was to investigate the relation between intake of various dairy products and the risk of RA in a nested case-control study.Me

Transition metal complexes play a crucial role in solar energy conversion. These coordination compounds have promising applications in dye-sensitized solar cells and photocatalysis, with particular interest in solar fuel production. However, many of the photoactive transition metal complexes used in light-harvesting applications are still based on rare and expensive metals from the transition meta
