We explain autonomy with full-fledged reference to the complementaristic conception of language and its introspective capabilities. This field that we refer to is understood to belong to a wider epistemic category than that of (the received view of) semiotics as well as of systems science. It follows from the linguistic complementarity that autonomies (self-references; independencies) can never be

This thesis concerns the application of artificial neural network techniques to space weather physics. The networks applied include multi-layer error-backpropagation, radial basis function, and self-organized maps. Different parts in the solar-terrestrial chain are analysed with the emphasis on developing methods for real time predictions of geomagnetic activity. The neural networks are general mo

Popular Abstract in Swedish Den globala uppvärmningen av vår jord påverkar inte bara lufttemperaturen, utan även haven blir varmare. Dessutom förespås en ökning i nederbörd vilket kommer att göra havens ytvatten mindre salta. Temperaturförändringen och den ökade nederbörden kan leda till att skiktningen, den s.k. vertikala stratifieringen, som finns naturligt i haven blir skarpare och starkare. StIncreasing precipitation and surface water temperature due to global change may strengthen stratification in coastal regions, which could influence the behavior of dinoflagellate diel vertical migration (DVM). DVM is a behavioral mechanism by which dinoflagellates can access photosynthetically active radiation near the surface, and nutrients at depth. During this process, cells may need to cross b

This book discusses the theories, methods and perspectives of the scholarly biography. The point of departure is the continuously growing interest in biography as a genre over the last decade in history, literature and other fields of the humanities. In the first section of the anthology, “The Biographical Genre”, three articles highlight general tendencies and problems in biography writing. Adopt

Popular Abstract in Swedish Bindväven är kroppens stomme och fungerar som stödjevävnad i alla organ, som t ex lunga, samt i hud, ben mm. I bindväven finns olika typer av celler beroende på vilken slags vävnad det är. Den forskning som presenteras här berör fibrös bindväv. Denna är en mjuk och elastisk variant, som finns i t ex lungorna, i motsats till ben. De celler som dominerar i den fibrösa binFibrous connective tissue contains fibroblasts distributed in a complex network of extracellular matrix molecules, such as proteoglycans. The small proteoglycans biglycan and decorin are composed of a protein core substituted with two and one glycosaminoglycan (GAG) chain, respectively. Proteoglycan metabolism is regulated differently during several processes including inflammation and wound heali

Popular Abstract in Swedish Utvecklingen av säkrare och mer miljövänliga processer är en av de största utmaningarna som den kemiska industrin står inför. I det här sammanhanget är katalys i tvåfassystem, bestående av vatten och organiska lösningsmedel, av största intresse eftersom den möjliggör en enkel återvinning av katalysatorn samtidigt som den minskar skadliga utsläpp och kostnader för återviThe steric and electronic properties of eight water-soluble phosphines (1-8) were investigated by different methods. Phosphines 1-6 were tested as ligands in palladium catalysed hydroxycarbonylation of styrene. In line with the proposal that a ligand with low basicity should facilitate nucleophilic attack of water on the acyl complex, the electron rich {4 - [Bis(2 - diethylaminoethyl)] - aminobenz

Abstract in Norwegian En översikt över terrorismens psykologi samt en presentation av en modell för analys av ondskans psykologi.

We present a novel method for tracing reflected reading and multimodal learning, based on a combination of eye tracking and cued retrospective verbal protocols. With the help of this method, we can trace pupils’ problem solving, their integration of text, pictures and graphics, connect the process of reflected reading to the product (scores, learning outcomes) and uncover pupils' reading strategie

Popular Abstract in Swedish Kroppens blodglukoskoncentration regleras av celler i de Langerhanska öarna i bukspottkörteln. β (beta)-celler frisätter insulin då sockerhalten i blodet ökar, tex efter en måltid. Insulin verkar via speciella membranbundna proteiner (receptorer) på celler i muskel, hjärta och fettväv och påverkar dessa att ta upp glukos från blodet. När blodsockerhalten sjunker, t.ex. We have investigated the in vitro effects of long-chain free fatty acids (FFAs) on mouse pancreatic α- and β-cells by a combination of electrophysiological recordings, intracellular Ca2+ ([Ca2+]i) microfluorimetry and hormone release measurements. Acute addition of the saturated FFA palmitate to intact islets doubled insulin as well as glucagon secretion in the presence of 1 or 15 mM glucose and t

The organization and regulation of genes for tetrapyrrole synthesis were studied in low G+C Gram-positive bacteria. Clusters of genes encoding enzymes for tetrapyrrole biosynthesis were cloned from Bacillus sphaericus, Bacillus stearothermophilus, Brevibacillus brevis and Paenibacillus macerans. The structure of the hem gene clusters was compared to that of other Gram-positive bacteria. The hemEHY
