In the evolution of bird migration, partial migration is assumed to be an important intermediate step between migration and residency. Partial migration is characterised by the existence of both migratory and resident individuals in a given population. Compared to regular migration, relatively little is known about partial migrants and their migratory performances. In my thesis, I have studied th
Objective: To study selective regional binding for tau pathology in vivo, using PET with [11C]PBB3 ([11C]methylamino pyridin-3-yl buta-1,3-dienyl benzo[d]thiazol-6-ol) in tauopathies, and in conditions not typically associated with tauopathy. Background: Tau imaging is a promising tool to study the link between tau and neurodegeneration. The specificity of tracers in vivo however remains uncertain
Popular Abstract in Swedish Mikroorganismer finns överallt! De klarar av att överleva i extrema miljöer, extrema pH, extrema temperaturer och kan motstå strålning och gift i doser som vi inte skulle överleva. Framförallt klarar mikroorganismer av att överleva i en specifik extrem miljö - människan. Hundratals olika mikroorganismer bor på och i oss, i ett antal som långt överskrider vårt eget cellaMicroorganisms are everywhere! They can tolerate many diverse extreme environments, such as the human body. Even though many of us might associate the word microorganism with infections and disease, most are actually either harmless or even beneficial for us. Those commensals often fight off more dangerous bacteria and might also directly benefit their host. The human skin harbors several differen
Oxidative stress results from a mismatch between production of reactive oxygen species (ROS) and the organism's capacity to mitigate their damaging effects by building up sufficient antioxidant protection and/or repair mechanisms. Because ROS production is a universal consequence of cellular metabolism and immune responses, evolutionary animal ecologists have become increasingly interested in invo
Activities with the aim to assess the effects of ISA on driver behaviour through experimental research were carried out. In order to investigate the regional differences in effects on driver behaviour when driving with ISA field trials were set up in Hungary and Spain. Complementary results were added from the Belgian ISA field trials. To investigate the effects on driver behaviour from different
The effects of data uncertainty in applications of the critical loads concept were investigated on different spatial resolutions in Sweden and northern Czech Republic. Critical loads of acidity (CL) were calculated for Sweden using the biogeochemical model PROFILE. Three methods with different structural complexity were used to estimate the adverse effects of SO2 concentrations in northern Czech R
Plant ecologists have placed increasing emphasis on a functional understanding of vegetation. One way to gain insight into the assemblage of vegetation communities is to investigate plant trait responses to environmental gradients or experimental treatments. We present simulations of responses of suites of traits to treatments differing in soil resources and disturbance intensity, in order to cons
With the exponential growth of the World Wide Web, automated subject classification has become a major research issue. Organizing web pages into a hierarchical structure for subject browsing has been gaining more recognition as an important tool in information-seeking processes.The most frequent approach to automated classification is machine learning. It, however, requires training documents and
This dissertation focuses primarily on the following aspects concerning music in theatre: 1) its experienced peculiarity – ontologically grounded, 2) its sounding scope, and 3) its various kinds of functions. I argue that the difference between spoken theatre and opera is a question of degree rather than essence, and consider such an assertion being especially valid for the music of these genres.
In this chapter, we will lay the foundation for the case studies in the subsequent chapters. To this end, we will make explicit our understanding of populism, which links the individual contexts discussed in the remainder of this book. In this book, we define populism as a political strategy and/or practice, realised in discourse, that is based on a dichotomy between "the people", who are unified
BACKGROUND: Programmed death-ligand 1 (PD-L1) expression on tumor cells is associated with poor prognosis in several malignancies, while partly contradictory and inconclusive results have been presented for colorectal cancer (CRC). This study aimed to evaluate PD-L1 as a prognostic biomarker in CRC by comparing three different antibody clones.METHODS: Patients surgically treated for CRC between Ja
Phosphoryl transfer plays key roles in signaling, energy transduction, protein synthesis, and maintaining the integrity of the genetic material. On the surface, it would appear to be a simple nucleophile displacement reaction. However, this simplicity is deceptive, as, even in aqueous solution, the low-lying d-orbitals on the phosphorus atom allow for eight distinct mechanistic possibilities, befo
This study presents a comprehensive investigation of the structural, microstructural, electrical, magnetic, and magnetoelectric properties of low-level substitution of Co3 + for Fe3+ ions in the perovskite B-site of BiFeO3 (BiFe1−xCoxO3, x = 0.01, 0.015 and 0.02). X-ray diffraction combined with Rietveld refinement confirms the retention of the rhombohedral R3c structure across all compositions, w
The German transition to renewable energies has so far been an example of a successful energy transition of a major economy. Even though this transition is criticized for being only a half-hearted solution, it is an important example of the attempt of a major economy to transit towards renewable energies and is therefore worth studying in its own rights. Thus, my aim in this thesis is the identifi
Packaging helps to protect the product and safety handover the product from producer to end user. When the packaging leaves the closed loop it creates environmental issues. Also, the material focused packaging development process creates trade-off among supply chain actors. The sustainable packaging would reduce the overall cost and environmental impact, increase the value of the packed product in
Problem: There are strong forces from for instance politicians, who want to allow third party access to the district heating market, as has already been done in the electricity and gas markets. But what would be the consequences of a third party access to the district heating market? Will it create a competitive market, and will it be able to put any pressure on the prices? What will be the conseq
