Lars-Eric Jönsson tar i den avslutande artikeln utgångspunkt i ett individuellt levnadsöde i 1900-talets Sverige. Det är en social problembiografi skriven av flera sociala och psykiatriska institutioner. Artikeln undersöker villkoren för hur biografin kom till och på vilket sätt den omskrivne presenterades. Jönsson konstaterar hur personakten snarare handlar om individens möte med dessa institutio
Kriminologer har skildrat hur unga män ofta har erfarenhet av att vara både brottsutsatt och gärningsman. Samtidigt tenderar dessa båda roller att betraktas som delar i ett statiskt motsatsförhållande, och brottsoffret och gärningsmannen som väsensskilda personer. I detta kapitel ska jag analysera samtalsintervjuer med tre unga män av invandrarbakgrund som utsatts för våld. I analysen kommer männe

Popular Abstract in Swedish Denna avhandling beskriver hur man kan använda en ny mätteknik, mikrodialys, för att följa det biokemiska händelseförloppet i hjärnan vid intensivvård efter svåra skallskador. Mikrodialys är en teknik som baseras på att olika ämnen i vävnadens interstitium, det vill säga området utanför cellerna, kan passera genom ett tubformat membran som omger en kateter. Katetern är In clinical situations with raised intracranial pressure (ICP) and impending insufficient cerebral blood flow (ischaemia), bedside information about energy metabolism in the brain would be helpful. Microdialysis is a technique that makes it possible to monitor the interstitial concentrations of various compounds in an organ. Intracerebral microdialysis with bedside analysis of metabolites related

We have analyzed the long-term success of various social learning heuristics. Specifically, we have examined their ability to persist and to replace other heuristics, and we have done this in two broadly different kinds of environments: environments in which the optimal behavior varies across space, or through time. Because each social learning heuristic also shapes its environment as individuals
The handling of biochemically functionalised beads or particles is becoming increasingly important in µTAS. Bead-based analysis of e.g. proteins can be made sensitive due to the large active surface area and flexible by chemical design of the bead surface. We have developed a microfluidic device utilising an array of integrated and individually controlled ultrasonic microtransducers for particle t
Book abstract: The book reviews recent observations of non-evolved and evolved binary populations in clusters and the field with special emphasis on statistical biases, incompleteness and distribution functions. Different binary types are considered: cataclysmic variables, super-soft X-ray sources, double degenerate binaries, Algol-type binaries, Be binaries, X-ray binaries, and Wolf-Rayet binarie
BCJR based source coding of image residuals is explored. From a trellis representation of the residual, a joint source-channel coding system is formed. The use of the BCJR algorithm is possible due to a procedure which transforms the residuals to a representation with independent identically distributed components having unit variance
The problem of robot drilling presents a significant challenge, due to the comparatively low mechanical stiffness of typical serial industrial robots. This compliance makes the robot deflect due to the cutting forces, resulting in poor hole quality. Recently, functionality for high-bandwidth force control has found its way into industrial robot control systems. This could potentially open up the p
Popular Abstract in Danish Ved CERN (Conseil Européen pour la Recherche Nucléaire) accelerer man protoner og bly-ioner op til næsten lysets hastighed, for derefter at kollidere dem med hinanden. Målet med dette er at forstå, hvordan de mindste ting i universet er bygget op, og hvordan de interagerer. Alle tidligere eksperimentelle data er kombineret til en enkelt teori, kendt som StandardModellen This thesis consider the improvement of the simulation tools used to describe high energy particle collisions. These simulation programs are normally referred to as event generators. The emphasis is on two specific parts of the event generation: the introduction of radiation of weak bosons associated with the collision and a new model for colour reconnection. Each collision contains significant
Popular Abstract in Swedish I vår kropp står ämnesomsättningen för nedbrytning av mat till kemiska ämnen som är nödvändiga för vår energiförsörjning, kroppsuppbyggnad och fortplantning. Varje cell i varje organism tillverkar eller tar upp små molekyler, som de sedan sätter ihop till stora molekyler. Samtidigt som detta sker så bryter cellerna ner molekyler som har blivit tillverkade. Ur detta får There are two fundamentally different ways by which a metabolite can be transferred between enzymes in metabolic pathways. If the two sequential enzymes cannot form a complex with each other, the metabolite must first be released from the producing enzyme to the reaction medium and then be transported to the consuming enzyme, via the reaction medium, by free diffusion. If the two sequential enzyme
Both numerical simulations and experimental measurements of small scale spontaneous ignition with different biomass fuels have been performed. In the experiments, temperature history was monitored at five different locations inside the fuel bed. The measured temperature history was used for validation of comprehensive threedimensional computer simulations which were carried out using a parallel fi
