Reliable information on solar activity over the Holocene period is important to predict the Sun in the future and to understand the mechanism behind the Sun-climate linkage. Presently, there are discrepancies in the proxy data of solar activity due to reasons that are not yet understood. This leads to major uncertainties in Holocene solar reconstructions. This PhD project aims to improve the Holoc
The effects of data uncertainty in applications of the critical loads concept were investigated on different spatial resolutions in Sweden and northern Czech Republic. Critical loads of acidity (CL) were calculated for Sweden using the biogeochemical model PROFILE. Three methods with different structural complexity were used to estimate the adverse effects of SO2 concentrations in northern Czech R
The interaction of blood coagulation factor X and its Gla-containing fragments with negatively charged phospholipid membranes composed of 25 mol% phosphatidylserine (PtdSer) and 75 mol% phosphatidylcholine (PtdCho) was studied by surface plasmon resonance. The binding to 100 mol% PtdCho membranes was negligible. The calcium dependence in the membrane binding was evaluated for intact bovine factor
Accident prediction models are often used to predict the number of accidents on segments and at intersections in the road network. Most often the models are developed for a total number of crashes for the facility, or crashes by severity. However, the frequency and severity of crashes of different types can be expected to vary with regards to the underlying phenomena that cause them to occur. To b
Antigenic diversity in pathogenic microbes can be a result of at least three different processes: diversifying selection by acquired immunity, host–pathogen coevolution and/or host specialization. Here, we investigate whether host specialization drives diversity at ospC (which encodes an immunodominant surface protein) in the tick-transmitted bacterium Borrelia afzelii. We determined prevalence an
While the so-called “end of public space” literature, focusing on encroachment of private interests and state surveillance, has contributed to critical thinking of access (or the lack thereof) to public space, and the loss of publicity of public space, the conceptual tools such literature offers to understand contestations in and over public space have remained underdeveloped or, at best, underexp
This thesis demonstrates the usefulness of sedimentary pigments as biomarkers of environmental change in estuarine systems and as biomarkers in lakes in relation to climate change. These are two fields where sediment pigment records as measured by high-performance liquid chromatography (HPLC) are emerging areas of study. A detailed study was undertaken to examine the effects of different storage o
Stability is a fundamental property affecting function, activity, and regulation of biomolecules. Stability changes are often found for mutated proteins involved in diseases. Stability predictors computationally predict protein-stability changes caused by mutations. We performed a systematic analysis of 11 online stability predictors' performances. These predictors are CUPSAT, Dmutant, FoldX, I-Mu
Popular Abstract in Swedish Vad är det för något i human mjölk som dödar cancer celler? Kan “fel” veckade proteiner vara nyttiga? Kan fett vara inblandat i protein veckning? Det är några av frågorna som tas upp i denna avhandling. Allt levande består av proteiner som i sin tur är uppbyggda av amino syror. Det finns 20 st. olika amino syror som på olika sätt kan länkas samman till proteinkedjor. DBy varying its secondary or tertiary structure a single protein can attain new biological functions. The amyloid forming proteins are the best known examples where a change in conformation leads to the formation of amyloid fibrils that accumulate in tissues and cause disease. a-lactalbumin in contrast, is an example of a protein that acquires a beneficial function when the conformation is altered

Feedbacks mechanisms are essential components of our climate system, as they either increase or decrease changes in climate-related quantities in the presence of external forcings. In this work, we provide the first quantitative estimate regarding the terrestrial climate feedback loop connecting the increasing atmospheric carbon dioxide concentration, changes in gross primary production (GPP) asso
Cykling är en viktig del av ett hållbart transportsystem. Det bidrar bl.a. till en bättre miljö och förbättrad folkhälsa. Syftet med arbetet är att undersöka vilka faktorer som kännetecknar en bra cykelstad, ur en infrastruktursynpunkt och vilka faktorer som kan leda till ökad cykling. I arbetet intervjuas representanter för kommunerna Lund, Malmö och Helsingborg om vilka infrastrukturella åtgärdeCycling is an important part of a sustainable transport system. It contributes among other things to a better environment and improved public health. The aim of this thesis is to investigate which factors characterize a good cycling city, from an infrastructural point of view, and which factors may lead to increased cycling. In the thesis, representatives of the municipalities of Lund, Malmö and H
Methane is one of the most important greenhouse gases, and the Arctic region plays an important role in its dynamics. Due to limited observations in this remote and often harsh environments, large uncertainties surround the role of the Arctic region in a warming climate. In this thesis, I examine the performance of the three low-cost solid state sensors, Figaro sensors TGS2600-B00, TGS2611-C00 an
The active site of sulfite reductase (SiR) consists of an unusual siroheme–Fe4S4 assembly coupled via a cysteinate sulfur, and serves for multi-electron reduction reactions. Clear explanations have not been demonstrated for the reasons behind the choice of siroheme (vs. other types of heme) or for the single-atom coupling to an Fe4S4 center (as opposed to simple adjacency or to coupling via chains
