The conventional inversion of surface waves depends on modal identification of measured dispersion curves, which can be ambiguous. It is possible to avoid mode-number identification and extraction by inverting the complete phase-velocity spectrum obtained from a multichannel record. We use the fast simulated annealing (FSA) global search algorithm to minimize the difference between the measured ph
The Mo/Cu-dependent CO dehydrogenase from O. carboxidovorans is an enzyme that is able to catalyse CO oxidation to CO2; moreover, it also expresses hydrogenase activity, as it is able to oxidize H2. Here, we have studied the dihydrogen oxidation catalysis by this enzyme using QM/MM calculations. Our results indicate that the equatorial oxo ligand of Mo is the best suited base for catalysis.

Avhandlingen handlar om samtida föräldraskap och skärmtid. Skärmtid används ofta i vardagligt språkbruk för att beteckna aktiviteter på och kring skärmteknologier, men det har även blivit ett fenomen som ofta beskrivs i termer av konfrontation, osäkerhet och frustration i hemmet (Livingstone & Blum-Ross 2020; Sandberg et al. 2024a). Föräldrar förväntas hantera och kontrollera deras barns skärmThe dissertation is about modern-day parenting in relation to what is commonly known as screen time. While screen time in everyday language is used to connote activities on screen technologies, it has become a phenomenon which often describes a site of struggle, uncertainty and frustration in the domestic space (Livingstone & Blum-Ross 2020; Sandberg et al. 2024a). Parents are expected to mana
Over the last decade the music festival sector grew enormously: in 2008 over a million festivalgoers gathered in the UK to share music and companionship. However in doing so musicfestivals generate large volumes of waste streams and consume large quantities of resources. Amusic festival of more than 40 000 people will produce in the order of 2000 tons of CO2e –with audience transportation and on s
To address global food security challenges caused by population growth and climate change, accurate prediction of crop yield is essential for sustainable agriculture. Winter wheat, a key global crop, faces production instability in regions like Sweden and Morocco due to extreme weather conditions. This study employed unmanned aerial vehicle (UAV)-based multispectral imagery and digital surface mod
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
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
Popular Abstract in Swedish Som ett skepp uti vilda havet, den kristna församlingen i ärkebiskop Laurentius Petris verk I 1593 års Uppsala mötes "förening om läran, ceremonier och kyrkotukt" finns följande avsnitt : Thernäst bejake och vederkännes vi oss alldeles vele holle vidh the Apostoliske, Niceniske och Athanasii symbola, såsom och vidh then äldste, rätte och oförrandrede Ausburgiske confeThe aim of this thesis is to present the ecclesiology of Laurentius Petri, a former student at Wittenberg who was archbishop of Uppsala from 1531 to his death 1573. He had a decisive role in the founding of the Church of Sweden, especially through his Swedish Church Ordinance(1571). Nevertheless most of his seventy-three writings are little known and have been rarely studied. Chapter one st
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
The research area of climate field reconstructions has developed strongly during the past 20 years, motivated by the need to understand the complex dynamics of the earth system in a changing climate. Climate field reconstructions aim to build a consistent gridded climate reconstruction of different variables, often from a range of climate proxies, using either statistical tools or a climate model
Utbildning på forskarnivå är den högsta akademiska utbildningen vid ett universitet. Forskarutbildningen innebär 4 års studier på heltid eller 8 års studier på deltid motsvarande 240 hp och avslutas med en doktorsexamen. Utbildningen förbereder dig för en fortsatt karriär inom akademin eller utanför universitetet. Huvudmålet för den medicinska utbildningen på forskarnivå är att utbilda forskare so

Oilseed rape fields are a very common crop in the agricultural landscape of southern Sweden, and they can harbour surprisingly many insect species. Some of them are herbivores that feed on various parts of the oilseed rape plant, others are natural enemies of the herbivores, and even more species are tourists from the surrounding landscape. In my thesis I have studied these insects and how their pOilseed rape fields are a very common crop in the agricultural landscape of southern Sweden, and they can harbour surprisingly many insect species.

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
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
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
