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
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
Antibiotic resistance is currently an extensive medical challenge worldwide, with global numbers increasing steadily. Recent data have highlighted wastewater treatment plants as a reservoir of resistance genes. The impact of these findings for human health can best be summarized using a One Health concept. However, the molecular mechanisms impacting resistance spread have not been carefully evalua
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
Current hemophilia B treatment guidelines recommend routine prophylaxis with factor IX (FIX) replacement products, tailored to maintain plasma activity at levels that will prevent bleeds. However, plasma FIX activity may not be the primary determinant or best indicator of hemostatic efficacy due to its extravascular distribution. FIX replacement therapy has evolved to include extended half-life (E
BACKGROUND: Hair cosmetics such as hair dyes, bleaching, waving, and cleansing products are composed of numerous chemical ingredients. Allergic reactions to these contact allergens, other than p-phenylenediamine, are rarely reported.OBJECTIVES: To study the incidence of patch test reactions to hair cosmetic allergens and identify the factors associated with hair cosmetic allergy in Thailand.METHOD
Abstract To estimate the timescale of hepatitis B virus (HBV) evolutionary history and analyzing its phylogeographic patterns, publically available HBV sequences were collected from GenBank. Among those, 412 sequences were from genotype A and 566 sequences were from genotype D. These sequences comprised the entire genome and represented samples obtained between 1982 and 2009 from different parts

Popular Abstract in Swedish Jesaja 40-55 representerar en av Gamla testamentets höjdpunkter. Här ackumuleras bilderna av Gud som Israels konung, herde, fader, moder, skapare och försörjare. Det är en befriande, nyskapande och mäktig Gud som tilltalar ett modlöst, förtvivlat och krossat Israel. Dessa kapitel domineras av budskapet om tröst och räddning till den grad att bibelforskningen sammanfattaThe theology of Isaiah 40-55 has two seemingly contradictory aspects: the tension between the consolatory message of deliverance, and the harsh tone of accusation. In this part of the Book of Isaiah, YHWH's return to his people is demonstrated through the accumulation of declarations about YHWH's ability and his will to deliver the Israelites from the exile. At the same time, the Israelites are ex
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
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 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 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
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
Procedural sedation and analgesia outside the operating theater have become standard care in managing pain and anxiety in children undergoing diagnostic and therapeutic procedures. The objectives of this study are to describe the current pediatric procedural sedation and analgesia practice patterns in European emergency departments, to perform a needs assessment-like analysis, and to identify barr
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
