Popular Abstract in Swedish Den här avhandlingen är ett bidrag till utvecklingen av en metodik som gör det möjligt att med hjälp av fossila pollen d.v.s. pollen som lagrats i mossar och sjöar, rekonstruera historiska och förhistoriska landskap så precist som möjligt vad gäller utbredning av skog, olika typer av öppen mark samt vegetationens sammansättning. Den tolknings metodik som för närvarande Fossil pollen records retrieved from peat and lake sediments have great potential for quantifying past plant cover. This thesis is a contribution to the development of a palynological interpretation tool for reconstructing past cultural landscapes in terms of plant abundance and distribution. The aims of this thesis are (1) to explore pollen-vegetation relationships in the ancient, traditional cul

Both natural and synthetic polyelectrolytes form strong complexes with a variety of proteins. One peculiar phenomenon is that association can take place even when the protein and the polyelectrolyte carry the same charge. This has been interpreted as if the ion-dipole interaction can overcome the repulsive ion-ion interaction. On the basis of Monte Carlo simulations and perturbation theory, we pro

This doctoral thesis deals with two closely interconnected phenomena, the adoption and diffusion of innovations. The research aims at developing both the theory of individual adoption decisions and the theory of the diffusion of an innovation in society. Especially how the pricing of an innovation tends to influence adoption and diffusion is focused. Two empirical studies within the telecommunicat

I describe briefly the status of the ARIADNE program implementing the Dipole Cascade Model and comment both on its performance at HERA, and the uncertainties relating to the extrapolation to LHC energies.

Previous studies have found a recognition bias for information consistent with the physical attractiveness stereotype (PAS), in which participants believe that they remember that attractive individuals have positive qualities and that unattractive individuals have negative qualities, regardless of what information actually occurred. The purpose of this research was to examine whether recognition b

The ATLAS Inner Detector is a composite tracking system consisting of silicon pixels, silicon strips and straw tubes in a 2 T magnetic field. Its installation was completed in August 2008 and the detector took part in data-taking with single LHC beams and cosmic rays. The initial detector operation, hardware commissioning and in-situ calibrations are described. Tracking performance has been measur

From the mid-1990s onwards, the humanities and social sciences have devoted a great deal of attention to the operations of the affects, and there has been much talk about "the affective turn". This article begins by looking at the impact of that phenomenon on scholarly and critical work on T. S. Eliot, a milder impact than one might have expected. It then goes on to investigate the interplay of em

Abstract in UndeterminedIn this paper we discuss the role of contrast in the theory of grammar and show that it is a complex concept cutting across focus and topic. We identify its main characteristics at the interface between syntax-phonology and pragmatics. Our main claim is that contrast is a complex information-structural notion that serves a double function: like focus, contrast is a highligh

Serotonin and dopamine are two monoamines which are known to interact with each other. Their role for suicidal behaviour, aggression and mood are reviewed in this chapter. We found a substantial amount of evidence for the relevance of a serotonin and dopamine model of aggression, and for aggression as a major risk factor for suicide. Evidence was found that serotonin and dopamine also may be invol

Objective . Hypoglycaemia is regularly accompanied by hypovolaemia. To suggest a mechanism for this phenomenon, we reviewed data from eight studies conducted by our group and examined the circumstances under which rebound hypoglycaemia develops after intravenous infusion of glucose solutions. Material and methods. Forty healthy volunteers and 40 patients received a total of 122 infusions of glucos

The literature on the relationship between the size of government and economic growth is full of seemingly contradictory findings. This conflict is largely explained by variations in definitions and the countries studied. An alternative approach – of limiting the focus to studies of the relationship in rich countries, measuring government size as total taxes or total expenditure relative to GDP an
