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

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

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

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

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

Mangroves provide numerous environmental benefits, such as carbon sequestration, water purification, climate change mitigation, and flood and Tsunami impact reduction. Despite these unique advantages, mangroves are threatened by the combined adverse impacts of human activities and climate change. Therefore, it is essential to implement reasonable practices to avoid further degradation of mangroves

3D-modeller är grunden i det som kallas BIM och är något som används mer flitigt inom byggbranschen men desto mindre inom anläggningsprojekt. BIM har utvecklats mer och mer för att underlätta samordningen av flera aktörer och lösa konflikter i olika faser och skeden. Med ytterligare dimensioner integreras även tid och kostnadsaspekten på projektet som resulterar i ett mer produktivt byggande. Gru3D-models are the base of what is called BIM. It is used more and more within in the construction industry over all, but not as much in the field of infrastructure projects. BIM is developed to coordinate several actors and resolve conflicts in different phases of the construction. With dimensions integrated in the model, such as time and cost aspect, it result in a more productive project. The m

Vad spelar Arktis för roll i klimatförändringarna? Denna avlägsna, och glest befolkade, del av världen utgör faktiskt en viktig del av klimatsystemet. Arktis spelar en betydande roll i kolets kretslopp; vilket innefattar såväl koldioxid och metan, två av de viktigaste växthusgaserna. Förändringar i koncentrationer av växthusgaser påverkar hur mycket värme som hålls kvar i jordens atmosfär. VåtmarkMethane 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

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

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

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

Matching habitat choice is a habitat preference mechanism based on self-assessment of local performance, such that individuals settle in the habitats that are best suited to their phenotypes, promoting local adaptation. Despite the important evolutionary implications of matching habitat choice, examples from natural populations are rare. One possible reason for this apparent rarity is that phenoty

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

In the broad field of biology, our researchers study everything from small cells to large ecosystems. Research projects include the forces of evolution, unsung heroes of the soil, how animals navigate and seeking answers to the mystery of ageing. Animals with unique abilitiesHow do birds, insects and some other animal groups manage to keep a straight course over long distances? The fascinating abi

Limiting climate Impact of plastics “Solutions to limit the climate impact of plastics” was the topic of the 2018 Climathon in Lund. The 24 hour hackathon gathered 54 participants and was thereby one of the larger among the 113 Climathons held simultaneous all around the world. Climathon in Lund was organised by a consortia of five very different organisations, Lunds Universitet, Lunds Kommun, Sys

Popular Abstract in Swedish Tuberkulos (tbc) är en av de sjukdomar som sedan tusentals år orsakat mest lidande för mänskligheten. Mycobacterium tuberculosis är den bakterie som orsakar tbc hos människor. Att vi lever tätare inpå varandra på grund av växande befolkning globalt gör att denna luftburna smitta kan fortleva. Fattigdom och undernäring är viktiga bidragande orsaker som förklarar varför dRapid, accurate diagnosis and management of TB in HIV-positive individuals is critical for the success of antiretroviral treatment programmes in primary health care in Sub-Saharan Africa. These studies aim to develop and evaluate methods for TB case finding in adults receiving care at Ethiopian health centres. The prevalence of active TB in a prospective cohort of 812 HIV-positive adults was deter
