This Master's thesis examines segregation between Swedes and immigrants in school, and more specifically segregation between the two elementary schools Vikingaskolan and Tunaskolan in Lund. This case provides a particularly interesting puzzle, since Lund doesn?t have any pronounced immigrant districts, and was also recognized nationally as best municipality for its schools (2004). In this thes

Populärvetenskaplig sammanfattning: Under de senaste årtiondena har norra Ghana drabbats av missväxt i samband med torka vid ett flertal tillfällen. Jordbrukarna i området är beroende av den mängd nederbörd som faller under den enda regnperioden, mellan april och september. En avvikelse från den årliga medelnederbörden kan därför medföra en reducering eller fullständig kollaps av spannmålsproduktiNorthern Ghana experiences one dry season per year, but severe droughts may occur more infrequently. This is of concern to the local farmers of the Tamne River Basin (northeast Ghana) who depend on adequate rainfall amounts during the rainy season. Unfavourable precipitation amounts may lead to catastrophic consequences. It is therefore crucial to develop methods for predicting the distribution of

Arbetet är utfört åt skogsforskningsstationen Mógilsá som ligger strax norr om Reykjavik. Forskningen inom Mógilsá bedrivs inom delar av eller för hela Island med inriktning inom exempelvis dendrokronologi, proveniensförsök, och studier av insekter. Sedan 1900-talets början har inplantering av exotiska trädarter blivit allt vanligare och i en allt större skala. Syften med inplanteringen är bland aThis study was made in an attempt to give the forest research centre Mógilsá a produced tetratherm map and a better understanding of how topography and temperature influence the growth of two tree species. The digital tetratherm map model, covering the northern part of Iceland, was developed to investigate the correlation between tetratherm and the growth of Picea sitchensis and Larix (sukaczewii

Oat is susceptible to several Fusarium species that cause contamination with different trichothecene mycotoxins. The molecular mechanisms behind Fusarium resistance in oat have yet to be elucidated. In the present work, we identified and characterised two oat UDP-glucosyltransferases orthologous to barley HvUGT13248. Overexpression of the latter in wheat had been shown previously to increase resis

While both innate and adaptive immune system mechanisms have been implicated in resistance against the chytrid fungus Batrachochytrium dendrobatidis (Bd), studies on the role of specific MHC haplotypes on Bd infection are rare. Here, we studied variation in MHC Class IIB loci in the common toad Bufo bufo along a latitudinal gradient across Sweden. In general, Swedish toad populations had few MHC C

Knowledge of price formation in fisheries is important in understanding effects of fisheries regulations and the support or resistance to regulations from different stakeholders. This article studies how demand can be traced out using wind speed on a fishing trip. Wind speed is strongly correlated with the quantities of Norwegian lobster (Nephrops) available on the market. Using wind variables as

This paper is an introduction to the topical collection dealing with the Post-glacial human subsistence and settlement patterns: insights from bones. The context of the Lateglacial and Early Holocene (ca. 16,000–6000 cal BP) in Europe offers the possibility to examine the response of terrestrial ecosystems to dramatic climatic changes and the evolution of subsistence among hunter-gatherers facing

There is considerable evidence that the act of participating in a survey can alter participants' attitudes, behaviors, and other outcomes in meaningful ways. Considering findings that this form of panel conditioning also impacts health behaviors and outcomes, we investigated the effect of participating in an intensive half-century-long cohort study on participants’ longevity. To do so, we used dat

Increasing air temperatures reduce the duration of ice cover on lakes and rivers, threatening to alter their water quality, ecology, biodiversity, and physical, economical and recreational function. Using a unique in situ record of freeze and break-up dates, including records dating back to the beginning of the 18th century, we analyze changes in ice duration (i.e., first freeze to last break-up),

Suppression of the J/ψ nuclear-modification factor has been seen as a trademark signature of final-state effects in large collision systems for decades. In small systems, the nuclear modification was attributed to cold-nuclear-matter effects until the observation of strong differential suppression of the ψ(2S) state in p+A and d+A collisions suggested the presence of final-state effects. Results o

The azimuthal variation of jet yields in heavy-ion collisions provides information about the path-length dependence of the energy loss experienced by partons passing through the hot, dense nuclear matter known as the quark-gluon plasma. This paper presents the azimuthal anisotropy coefficients v2, v3, and v4 measured for jets in Pb+Pb collisions at sNN=5.02 TeV using the ATLAS detector at the LHC.

A search for decays of pair-produced neutral long-lived particles (LLPs) is presented using 139 fb−1 of proton-proton collision data collected by the ATLAS detector at the LHC in 2015–2018 at a centre-of-mass energy of 13 TeV. Dedicated techniques were developed for the reconstruction of displaced jets produced by LLPs decaying hadronically in the ATLAS hadronic calorimeter. Two search regions are
