Popular Abstract in Swedish Organiska miljögifter finns idag över hela världen inklusive Arktis och Antarktis. Miljögifter sprids lätt i atmosfären p.g.a. av de är flyktiga dvs övergår i gasfas. Trots att flera av dessa substanser har varit förbjudna att använda i över 20 år finns de idag kvar i naturen i höga halter. Flera av de organiska miljögifterna är svårnedbrytbara och har mycket lätt för aConcentrations of persistent organic pollutants (POPs) in aquatic biota are dependent on several factors both on individual and on system level. Bioaccumulation of POPs in pelagic biota in lakes as well as fish in streams has been shown to be dependent on nutrient regime of the system. In lakes, POP concentrations in pelagic biota decrease with increasing lake trophy. In this thesis POP bioaccumul

This dissertation studies the theme of illness in Swedish fiction from the first decade of the 21st century. The aim is to present a wide-ranging discussion about illness as a contemporary literary theme. The selection of texts has been confined to a short time-span – a decade – in order to acknowledge that themes of illness are temporally and culturally situated. Seven novels are discussed in dep

Differential dijet cross sections in diffractive deep-inelastic scattering are measured with the H1 detector at HERA using an integrated luminosity of 51.5 pb-1. The selected events are of the type ep → eXY, where the system X contains at least two jets and is well separated in rapidity from the low mass proton dissociation system Y. The dijet data are compared with QCD predictions at next-to-lead

Present-day demands on combustion equipment are increasing the need for improved understanding and prediction of turbulent combustion. Large Eddy Simulation (LES), in which the large-scale flow is resolved on the grid, leaving only the small-scale flow to be modeled, provides a natural framework for combustion calculations as the transient nature of the flow is resolved. In most situations, howeve

Denna bok är resultatet av ett samarbete mellan arkitekter och sociologer. Den handlar om de offentliga rummen i städernas periferi. Boken sätter periferin i centrum av två skäl. För det första sker de mest radikala omdaningarna av det befintliga stadslandskapet för närvarande i utkanten av de större städerna. Det är här de nya tillväxtföretagen etablerar sig, och det är här nya befolkningsgrupper

Time resolved X-ray diffraction has been used to study acoustic oscillations in InAs/Sb nanowires with diameters of 80 nm and 40 nm in order to determine the speed of sound in the wires.

Several immunodeficiency-related genes are known and a numb er of disease causing mutations have been identified. Immunodeficiency related mutation information have been collected into IDbases. We are currently maintaining 15 registries, which are available at http://www.uta.fi/imt/bioinfo/. The databases are available for the following disorders: adenosine deaminase, CD3 epsilon, CD3 gamma, JAK3,

The generation of ab initio three-dimensional (3D) models is a bottleneck in the studies of large macromolecular assemblies by single-particle cryo-electron microscopy. We describe here a novel method, in which established methods for two-dimensional image processing are combined with newly developed programs for joint rotational 3D alignment of a large number of class averages (RAD) and calculati

In this paper, we first present a survey of existing color buffer compression algorithms. After that, we introduce a new scheme based on an exactly reversible color transform, simple prediction, and Golomb-Rice encoding. In addition to this, we introduce an error control mechanism, which can be used for approximate (lossy) color buffer compression. In this way, the introduced error is kept under s
