Questions: To what extent does the long-term process of grassland succession reflect changes in nutrient availability or other effects of grassland history? Plant communities in ancient, semi-natural pastures include many species associated with nutrient-poor soils. However, semi-natural pasture communities can also develop on previously arable sites — as nutrient levels decline over time. In Euro
Questions Can the model performance of the landscape reconstruction algorithm (LRA) for small forest hollows be validated through comparison to inventory-based vegetation reconstructions from the last 150yrs? Does the application of LRA and the comparison to historical data enhance interpretation of the pollen record? Location Denmark. The Gribskov-Ostrup small forest hollow (56 degrees N, 12 degr
This thesis presents structural and morphological studies of semiconductor nanostructures, namely quantum dots, nanowires and a dilute ferromagnetic semiconductor. These nanostructures are investigated on the atomic scale using cross-sectional scanning tunneling microscopy (XSTM). Indium arsenide (InAs) quantum dots in both an indium phosphide (InP) and GaAs matrix are studied. The InAs/InP quantu
Construction in rock is associated with risks because knowledge of the geology and ground conditions is limited. Unforeseen rock conditions involve a large risk to the project and can in the end entail delays and extra costs. To minimize the risks, an optimized pre-investigation program has to be conducted where essential information is gathered in order to make the best decisions throughout the c
During the course of this three-year project, we have studied aeolian deposits at 70 sites within sixteen areas in south-central Sweden. Inland dunes have been the focus, but some sites with coversand and coastal dunes have also been investigated. We have mapped dune morphology, mainly by LiDAR-based remote sensing, studied the internal sediment architecture by ground-penetrating radar profiling a
I tidigare forskning om krig presenteras ofta ensidiga bilder av fenomenen krigsvåld, offerskap och försoning. Denna bok utgår från berättelser av överlevande efter kriget i Bosnien under 1990-talet. Syftet är att analysera hur de intervjuade beskriver dessa fenomen samt vilka diskursiva mönster som framträder i konstruktionen av begreppen ”offer” och ”förövare”. Mina frågeställningar är: Hur beskThis book analyzes verbally depicted experiences of survivors from the war in Bosnia and Herzegovina. One purpose to describe how the actors portray the social phenomenon of “war violence” “victimhood” and “reconciliation”, and the second aim is to analyze discursive patterns that emerges in the creation of the terms “victim” and “perpetrator”. My research questions are: (1) How do the interviewee
Organiserad brottslighet är ett väldigt aktuellt ämne som diskuteras såväl i Sverige som internationellt. Diskussionerna rör bl.a. den organiserade brottslighetens struktur, hur utbredd den är, dess medlemmar, dess kriminalitet och det hot den innebär mot samhället. Många har starka åsikter gällande organiserad brottslighet och det talas om att krafttag mot den behöver tas och olika åtgärdsprogramOrganised crime is a well-discussed subject matter. There are questions regarding its structure, how widespread it is, the individuals involved with it, its crimes and the potential threat to our society it amounts to. These questions are talked about in many different arenas, in Sweden as well as internationally, and the opinions regarding organised crime are many and strong. The fight against it
Developing high-temperature proton exchange membranes (HT-PEMs) that simultaneously achieve high proton conductivity, strong phosphoric acid (PA) retention, and long-term chemical stability remains a major challenge, particularly due to PA-induced plasticization and radical-induced oxidative degradation. Here, we develop a side-chain engineering strategy to decouple PA-binding sites from the polym

Catalytic breakdown of polysaccharides can be achieved more efficiently by means of the enzymes lytic polysaccharide monooxygenases (LPMOs). However, the LPMO mechanism has remained controversial, preventing full exploitation of their potential. One of the controversies has centered around an active site tyrosine, present in most LPMO classes. Recent investigations have for the first time obtained

The past and present distribution of Lobaria pulmonaria in Denmark, northern Germany, northwestern Poland and nemoral parts of Skåne, Blekinge, southwesternmost Småland and southern Öland (Sweden) has been studied. Of 124 localities visited between 2015 and 2018, L. pulmonaria was confirmed at 64 sites, at each of which its habitat ecology and viability were investigated. It is almost extinct in S
An evaluation has been made of the capability of rapeseed oil to dissolve polycyclic aromatic hydrocarbon (PAH) crystals in a biphasic system and of its capability to extract PAHs from polluted soil in a two-liquid-phase (TLP) slurry system. Up to 220 g l(-1) of the crystalline hydrocarbons could be dissolved in the organic phase, indicating oil/water-partitioning coefficients of 10(5). When soil
The funnel metadynamics method enables rigorous calculation of the potential of mean force along an arbitrary binding path and thereby evaluation of the absolute binding free energy. A problem of such physical paths is that the mechanism characterizing the binding process is not always obvious. In particular, it might involve reorganization of the solvent in the binding site, which is not easily c

Anthropogenic activities such as hydropower exploitation have been one of the main drivers of anadromous fish biodiversity loss during the past century. This has led to genetic homogenization and to the reduction of positive mechanisms such as the “portfolio effect”. In this study we propose the first comprehensive analysis of the genetic differences in Salmo salar and Salmo trutta populations in
The conservation value of sandy habitats for a flora and fauna adapted to open, light, dry, warm, and often nutrient-poor conditions, is well recognized. Today this environment is threatened by lack of disturbance, fragmentation and exploitation, acidification and increased levels of nitrogen and phosphorus. Traditional management such as mowing and grazing have proven unsuitable for restoring pop
