Typical bogs in the boreal forest zone can be characterised by hummock and hollow micro-topography and sparsely vegetated surfaces. Their energy balance has been studied much less than for other types of surface, i.e. fields and forests. Micrometeorological measurements were carried out in central Sweden at two bogs in different summer seasons. From the measured profiles of wind speed, air tempera
A novel method was developed for studying the diffusion of proteins through poly(D,L-lactide-co-glycolide) (PLG), using a diffusion cell. To develop improved formulations for the controlled release of encapsulated drugs it is important to understand the underlying release mechanisms. When using low-molecular-weight PLG as the release-controlling polymer, diffusion through the pores is often propos
Popular Abstract in Swedish Denna avhandling består av tre olika uppsatser. Den första uppsatsen, Technical Efficiency and Ownership: The Case of Booking Centres on the Swedish Taxi Market” behandlar problemet med konkurrens på lika villkor. Upprinnelsen till uppsatsen var diskussioner mellan privata och offentliga aktörer på den svenska taximarknaden. De privata aktörerna hävdade att de offentligThis thesis consists of three different essays, all of which have arisen from a practical problem. In the first essay, “Technical efficiency and ownership: The case of booking centers in the Swedish Taxi Market” the purpose is to examine the question of competition on an equal basis between privately and publicly owned booking centers in the Swedish taxi market. One way to answer this question is
Popular Abstract in Swedish Torgny Segerstedt, den kände chefredaktören för Göteborgs Handels- och Sjöfartstidning, hade utkämpat strider före nazismens tid. Som ung kallades han till docent till Lund på en underkänd avhandling. Disputationen hade ägt rum i maj 1903 vid den teologiska fakulteten i Uppsala. Efter underkännandet beslöt alltså den teologiska fakulteten i Lund att kalla Segerstedt tilOn 1st September 1903, the Faculty of Theology at the University of Lund took the decision to appoint Torgny Segerstedt as a senior lecturer in spite of his failed doctoral dissertation. The public defence of his thesis had taken place on 28th May in the same year before the Faculty of Theology at Uppsala. It was thus after his failure that the Faculty at Lund nevertheless decided to invite him to
Background: Selective dorsal rhizotomy (SDR) is an operation method that decreases the degree of spasticity with long-lasting beneficial effects for children with spastic diplegia. Children undergoing SDR are postoperatively in severe pain, a pain related to both the extensive surgical exposure with multilevel laminectomy and the nerve root manipulation. Various pain management strategies for chil
1 Two new concepts describing the origin of insects caught ill an attractive trap are presented. 2 Male European pine sawflies Neodiprion sertifer Geoffroy (Hymenoptera: Diprionidae) were marked and released from 50, 100, 200, 400 and 800 m in the four cardinal directions around a centrally placed pheromone trap. 3 Based on linear regression of transformed data, we calculated the seasonal sampling
Objectives: To evaluate the effects of cariporide on all-cause mortality or myocardial infarction at 36 days in patients at risk,of myocardial necrosis after coronary artery bypass graft surgery. Methods: In the coronary artery bypass graft cohort of the GUARD During Ischemia Against Necrosis trial, patients greater than or equal to 18 years who required urgent coronary artery bypass graft, repeat
Application of C-rich plant residues can change the soil system from C-limitation for microbial growth to limitation by other nutrients. However, the initial nutrient status of the soil may interact with the added amount of residues in determining limitation. We studied this interactive effect in soils from the Harvard Forest LTER, where annual addition of N since 1988 has resulted in soils with d
Variations in health between neighborhoods are well known and the conceptualization of social capital has contributed to an understanding of how contextual factors influence these differences. Studies show positive health-effects from living in high social capital areas, at least for some population sub-groups. The aim of this qualitative study was to understand what constitutes a 'health-enabling
AimTo project the potential European distribution of seven broad habitat categories (needle-leaved, broad-leaved, mixed and mediterranean forest, urban, grassland and cropland) in order to assess effects of land use, climate change and increase in CO2 on predicted habitat changes up to the year 2050. LocationEurope. MethodWe modelled the response of European vegetation to changes in land use, clim
Aim The aim here was to assess whether the present-day assemblage of subantarctic flowering plants is the result of a rapid post-Last Glacial Maximum (LGM) colonization or whether subantarctic flowering plants survived on the islands in glacial refugia throughout the LGM. Location The circumpolar subantarctic region, comprising six remote islands and island groups between latitudes 46 degrees and
Chemical signals are prevalent in sexual communication systems. Mate recognition has been extensively studied within the Lepidoptera, where the production and recognition of species-specific sex pheromone signals are typically the defining character. While the specific blend of compounds that makes up the sex pheromones of many species has been characterized, the molecular mechanisms underpinning
Background: The Brief Obsessive Compulsive Scale (BOCS), derived from the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and the children's version (CY-BOCS), is a short self-report tool used to aid in the assessment of obsessive-compulsive symptoms and diagnosis of obsessive-compulsive disorder (OCD). It is widely used throughout child, adolescent and adult psychiatry settings in Sweden but has n
Popular Abstract in Swedish Alla människor blir dagligen utsatta för olika typer av främmande organismer som kan förorsaka kroppen skada. Därför har vi utvecklat celler som har till uppgift att "döda" och avlägsna allt främmande som kommer in i kroppen, det så kallade immunförsvaret. Immunförsvaret består av ett komplicerat nätverk av celler och molekyler som tillsammans skyddar oss om vi utsätts This thesis deals with the interactions between superantigens and their receptors. Superantigens are proteins that are secreted by various bacteria, such as Staphylococcus aureus and Streptococcus pyogenes. Superantigens are able to cross-link T cells and antigen presenting cells by binding to the T cell receptor (TCR) and MHC class II. They bind as unprocessed antigens and activate up to 20 % of
In this chapter, I discuss some effects on the ‘creative classes’ in Sweden and Scandinavia due to developments during roughly the last decade. In this period, a majority of the feature film making but also some documentary and TV-production has moved away from Stockholm, the capital, to newly established, regional production centres. A similar process has been going on for a while in other parts
Popular Abstract in Swedish Hur är det möjligt att planera om en kommun från arbetarstad till kunskapsstad? Idag har en rad svenska och europeiska kommunledningar ambitionen att återuppfinna städer genom att tvätta bort industristaden och ersätta den med en kunskaps-, informations-, kultur-, och/eller evenemangstad. Den här formen av kommunal utvecklingsplanering har genererat en rad olika frågor What are the discursive pre-conditions for planning? In this dissertation the author analyzes and critically assesses the assumptions which underlie our thinking about planning. This is done in an analysis of firstly, how planning is legitimized, and secondly, what consequences these forms of legitimation have for planning theory as well as for planning as a political practice. The author describ
Oxidative degradation is a serious threat to long-term use and recyclability of polymers. Successful recycling of polymeric quality products requires characterization of the polymer material after reprocessing and use. Lately, a growing awareness of the heterogeneous nature of degradation has developed in terms of physical spreading, non-uniform distribution of stabilizer, physical loss of stabili
Context. The formation and evolution of the Milky Way bulge is not yet well understood and its classification is ambiguous. Constraints can, however, be obtained by studying the abundances of key elements in bulge stars. Aims. The aim of this study is to determine the chemical evolution of C, N, O, and a few other elements in stars in the Galactic bulge, and to discuss the sensitivities of the der
Popular Abstract in Swedish Populärvetenskaplig sammanfattning av avhandlingen "Invading Herbivory. Effects of the Golden Apple Snail (Pomacea canaliculata) in Asian wetlands". 1980 förde några affärsmän ett okänt antal individer av den sydamerikanska vattensnäckan Pomacea canaliculata till Taiwan. Snäckorna skulle odlas i dammar och säljas som människoföda på marknader i Asien och överskottet skThe South American golden apple snail (Pomacea canaliculata) was intentionally introduced to aquacultures in South East Asia to produce snails for human consumption, but the aquatic snails soon escaped and started to consume large amounts of rice seedlings. The aim of this thesis was to quantify the effects of this invasive herbivore on aquatic plants in natural wetlands since previous research h
Vitellogenin (VTG) is a well known protein biomarker for exposure to environmental estrogens and possible endocrine disruption in fish. VTG is very dominant in plasma after the onset of vitellogenesis and the protein is heavily phosphorylated. This enables indirect quantification through measurement of alkali-labile protein bound phosphate (ALP) as an alternative to the more expensive enzyme linke
