Popular Abstract in English It is possible to disagree on nearly everything when it comes to human agency. Nonetheless, certain things are written in stone. One thinks. One acts. One makes mistakes. My focus in this dissertation is on these three simple facts and the relation between them. I am fascinated by the different roles that knowledge plays with each: that is, the kind of knowledge one hasIt is possible to disagree on nearly everything when it comes to human agency. Nonetheless, certain things are written in stone. One thinks. One acts. One makes mistakes. My focus in this dissertation is on these three simple facts and the relation between them.

The properties of bimetallic Ni-Rh nanowires, fabricated by decorating the steps of vicinal Rh(111) surfaces by stripes of self-assembled Ni adatoms, have been probed by STM, photoemission, and ab initio density functional theory calculations. These Ni-Rh nanowires have specific electronic properties that lead to a significantly enhanced chemical reactivity towards oxygen. As a result, the Ni-Rh n

We describe preliminary results of an acoustic-phonetic study of voice imitations, which is ultimately aimed towards developing an explanatory approach to similar-sounding voices. Such voices are readily obtained by way of imitations, which were elicited by asking an adult-male, professional imitator to utter two tokens of the Swedish word “hallå” in a telephone-answering situation and three Swedi

In this paper we consider Mark Bedau’s notion of weak emer- gence (WE) and relate it to various attempts to objectively construe complexity. We argue that the heavy reliance on a specific notion of complexity risks rendering the concept superfluous. Furthermore we discuss what sort of systems might reasonably be understood as exhibiting emergence at all and point out that the macro-level needs to

Disulfide bonds in proteins are found between cysteine residues and are usually important for either function or stability of proteins. Thiol-disulfide oxidoreductases catalyse the formation or breakage of disulfide bonds in proteins. The gram-positive endospore-forming bacterium Bacillus subtilis contains several membrane-bound thiol-disulfide oxidoreductases. BdbA, BdbB and CcdA have been descri

The major input signals entering the PID controller are; the setpoint, the process output, and measurable load disturbances. By feeding these signals through suitable filters, the properties of the feedback loop can be improved significantly. This presentation will treat setpoint handling, feedforward from load disturbances, TITO (two input two output) control, noise filtering, and process dynamic

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
