The research project "Exclusive metalworking in rural settings" was instigated in 2013 with funding from Berit Wallenbergs foundation. The projects objective is to survey sites housing remains of multimetal craftsmanship of the late Iron Age and medieval periods outside urban contexts. This article aims to contextualize preliminary results from the project by evaluating its chosen source material
Phasor measurement signals are used as only input to a wide-area power system stabilizer to increase interarea mode damping of the Icelandic system. Modal analysis and time simulations of a detailed model show that frequency difference as PSS input gives a damping improvement that is robust to drastic changes in system topology. Field data from phasor measurement units indicate high signal quality
In vitro studies have revealed intriguing properties of parallel fiber synaptic transmisson. Most notably, these synapses have been shown to induce highly variable synaptic responses, have a pronounced paired pulse facilitation and to induce later, variable synaptic responses in their target neurons. In the present study, whole cell recordings from stellate cells and basket cells were made to eval

Popular Abstract in English This thesis considers a model of high energy particle collisions. The model is based on the so called BFKL formalism which is valid only at low x, that is collisions at very high energies, such as at the LHC. The intial state of the incoming particles are simulated by colour dipoles in transverse space evolved through rapidity. With this approach, all fluctuations are dThis thesis considers a model of high energy particle collisions. The model is based on the so called BFKL formalism which is valid only at low x, that is collisions at very high energies, such as at the LHC. The intial state of the incoming particles are simulated by colour dipoles in transverse space evolved through rapidity. With this approach, all fluctuations are dynamically described, allowi
Popular Abstract in Swedish Hur påverkas djurplanktonsamhällen av klimatförändringar och vilken betydelse har vilostadier? Populärvetenskaplig sammanfattning av “Ecology of zooplankton communities: climate, dormancy and benthic-pelagic coupling”, doktorsavhandling i Limnologi vid Ekologiska institutionen, Lunds Universitet, 2003. Djurplankton är sjöars motsvarighet till betande kossor och de mikThis thesis describes how influences, such as top down and bottom up forces, shape zooplankton communities in shallow lakes. I have also extended the traditional food-web theory by investigating the effects of climate on total biomass, taxonomic composition, and temporal properties of zooplankton communities. A field experiment showed that the total biomass of both phytoplankton and zooplankton in
Research in theoretical chemistry is aimed at finding computational algorithms that produce as accurate results as possible, for as large molecules as possible, with a minimum of computational effort and to apply these methods to molecular systems of chemical interest. The most accurate theoretical methods, often referred to as ab initio methods, are derived from the fundamental laws of physics an
En genomgång av hur den bibliska gestalten Mirjam presenterats i rabbinsk litteratur och hur den senare använts och tolkats inom modern feministisk judendom.
En del personer går upp i vikt, andra inte. En viktig förklaring är överkonsumtion, men det finns också andra: låg ämnesomsättningshastighet, hög insulinkänslighet, låg energikostnad vid rörelse och låg fettförbränning. Alla dessa fenomen styrs av våra hunger- och mättnadssignaler. I boken beskrivs de senaste upptäckterna om hunger- och mättnadssignaler samt belöningssystem. En kunskap som ger os
Beck Ungdomsskalor består av fem korta självskattningsskalor för bedömning av emotionell och social problematik hos barn och ungdomar. Skalorna är standardiserade och normerade på cirka 2400 svenska skolbarn. Manualen innehåller även anvsiningar för administrering till yngre åldersgrupper samt data från kliniska grupper.

Abstract in Norwegian På kort har øya Ko Lanta utviklet seg til det stedet i Thailand med flest svensker. Etter tsunami katastrofen i desember 2004 har utviklingen gått fort og migrasjon til øya har blitt veldig populært av ulike grunner. Lokalsamfunnene og områdene som tidligere var bebodd av havnomader og fattige muslimske fiskere er nå i ferd med å bli fortrengt av skan- dinaver som bygger hus
A comprehensive experimental study of the dynamics and rheology of concentrated aqueous dispersions of polyethylene glycol-grafted colloidal spheres is reported. The study focuses on good solvent conditions, for which excluded-volume interactions dominate. At high concentrations a glass transition is evident from the nondecaying component of the intensity correlation function measured with three-d
