The present contribution describes some simulations of the observation of binaries with GAIA. The results do not differ fundamentally from earlier estimates, e.g. in GAIA's Concepts and Technology Study Report (ESA-2000-SCI-4), but they are based on more realistic assumptions and much more extensive numerical work.
Popular Abstract in Swedish MHC upptäcktes för 60 år sedan då George Snell konstaterade att möss som var genetiskt lika inte stötte bort transplanterad hud medan genetiskt olika möss gjorde det. Men det var inte förrän långt senare som man insåg vilken roll som MHC spelar i immunförsvaret hos alla vertebrater. Sedan ett par decennier tillbaka är detta ett välstuderat område speciellt hos människanIn birds the major histocompatibility complex (MHC) organization differs both among and within orders. Galliformes often have simple arrangements with few transcribed MHC genes whilst many songbirds (Passeriformes) have a complex arrangement with many MHC genes and also presence of pseudo-genes. In this thesis I have partly characterized MHC class I in house sparrows (Passer domesticus), sequencin
This report focuses on critical metals in Waste from Electrical Electronic Equipment (WEEE) and their recycling possibilities. The criticality is defined in terms of demand. The EU needs access to these metals and recycling can be an important part of the supply-strategy. The report covers assessments of (1) the potential amount of critical metals in the selected product groups, and (2) the actual
The desert locust, Schistocerca gregaria, is a polymorphic insect that occurs in two morphological and physiological distinct phases, solitary and gregarious, depending on population density. The two phases are reversible at any developmental stage. The gregarious phase produces and uses stage-specific pheromones, that keep the swarm together. In my thesis, I investigated the functional morphology
Anomalous background due to charging in the proton-induced X-ray analysis of insulators is eliminated by inserting a heated carbon filament or by raising the pressure in the sample chamber.
Abstract. The essay aims at integration of different concepts of meaning developed in semiotics, biology, and cognitive science, in a way that permits the formulation of issues involving evolution and development. The concept of sign in semiotics, just like the notion of representation in cognitive science, have either been used so broadly as to become almost meaningless, or they have been outrigh
Popular Abstract in Swedish SVENSK SAMMANFATTNING Den kliniska effekten av läkemedel som administreras till näsa eller lunga beror på läkemedlets egenskaper och på dess lokala deposition. Depositionsstudier är därför värdefulla för att kunna karakterisera olika beredningar. Depositionen påverkas av partiklarnas storlek och hastighet, genom att stora partiklar med hög hastighet ger upphov till en hThe local deposition, pharmacokinetics, and systemic activity of inhaled and intranasal glucocorticosteroids in different formulations and devices(ICSs) has been investigated. After nasal administration of the ICS budesonide (Bud), the systemic availability (F) was found to be significantly higher from an aqueous pump spray and from the powder inhaler Turbuhaler, than from a pressurized metered do
Popular Abstract in Undetermined Vårt immunförsvar består av molekyler, celler, och barriärer som har till uppgift att hålla oss friska genom att avlägsna eller stänga ute virus och skadliga mikroorganismer. På alla kärnförsedda celler i vår kropp sitter en stor mängd MHC klass I-molekyler, strukturer som kan liknas vid korgar. I varje korg ligger en peptid som är ett fragment av något som finns iHuman leukocyte antigen class I (HLA-I) molecules are present on all nucleated cells and present the cell content to cytotoxic T lymphocytes in the form of peptides. Maturation of HLA-I occurs in the endoplasmic reticulum and results in stable peptide-HLA-I complexes, in the presence of proper quality control. For proper peptide binding most HLA-I molecules interact with the peptide-loading comple
Mitochondrial permeability transition (MPT) is induced in isolated brain mitochondria by calcium and oxidants and is inhibited by adenine nucleotides. When induced, MPT is associated with equilibration of solutes of <1500 Da across the inner mitochondrial membrane. A persistent induction of MPT depolarizes the inner membrane and causes cessation of ATP synthesis, swelling of the matrix, and bursti
This article analyses the doctrine of free will (autexousion) in the confessions of St. Peter Mogila and Dositheos II Notaras of Jerusalem. Free will is a central concept in Eastern Christian anthropology and these two monuments of theology represent how the understanding of the concept of free will developed in Eastern Orthodox theology in the context of the confrontation with Western theologies
