It is widely accepted that the bioavaiiability, toxicity, and mobility of trace metals are highly dependent on complexation reactions with functional groups in natural organic matter (NOM). In this study, the coordination chemistry of Cd in NOM was investigated by extended X-ray absorption fine structure spectroscopy. Soil organic matter (SOM) from different types of organic soils and dissolved or

It is widely known that the apolipoprotein E (APOE) ɛ4 allele imposes a higher risk for Alzheimer's disease (AD). Recent evidence suggests that exposure to air pollution is also a risk factor for AD, and results from a few studies indicate that the effect of air pollution on cognitive function and dementia is stronger in APOEɛ4 carriers than in non-carriers. Air pollution and interaction with APOE

The isopod Oniscus asellus was fed wood pieces. The fecal pellets produced during 6 days were reingested twice. Both fresh and ageing pellets were examined for microorganisms and nitrogen compounds including proteins and bacterial cell wall compounds, d-alanine and diaminopimelic acid. In old pellets, the plate counts of fungi decreased but that of bacteria as well as the concentrations of protein

The purpose of this study is to explore the lived experience of sexuality for people with physical disabilities using formal personal assistance services in Sweden, from their own perspective. This is analyzed in relation to the aims of personal assistance services according to Swedish law, which states that they should be framed in terms of autonomy, integrity and self-determination making it pos

This document presents design considerations of a sample for accelerated thermal aging tests. The proposed specimen is a parallel wired solenoid that is evaluated by using an axi-symmetric 2D finite element (FE) model in Comsol multi-physics. The aim of the design model is visualizing an interior stress distribution of an idealized coil in order to interpret the physics-of-failure in a more comple

Background Problem gambling is a public health issue and its comorbidity with other health conditions may provide an opportunity for screening in healthcare settings; however, a high level of uncertainty and a lack of research in the field remains. The objective of this study is to investigate potential associations between problem gambling and numerous other health conditions, including substance

Compared to other organisms in which the fatty acyl desaturases (FADs) are mostly involved in normal cellular lipid metabolism, moth FADs have evolved extent functions in the biosynthesis of sex pheromones. Female moths releasespecies-specific sex pheromones to attract conspecific males over a long distance for mating. Moth FADs are key enzymes producing the great diversity of moth sex pheromones.

In this work, a combination of sonication and carbon dioxide expanded liquid extraction (SA-CXLE) is used for the first time for the extraction of lipids from berry seeds. Three solvents (ethanol, methanol and ethyl lactate) are screened for the best recoveries of total lipids. Ethanol is selected due to its efficiency, greenness and sustainability. The effects of operation variables including tem

Background: National guidelines are important instruments in reducing inappropriate antibiotic prescriptions. Low adherence to guidelines is an acknowledged problem that needs to be addressed. Method: We evaluated established characteristics for guidelines in the guidelines for lower respiratory tract infection, acute otitis media and pharyngotonsillitis in primary care. We studied how doctors use

Progresses in reconstructing Earth's history of biomass burning has motivated the development of a modern charcoal dataset covering the last decades through a community-based initiative called the Global Modern Charcoal Dataset (GMCD). As the frequency, intensity and spatial scale of fires are predicted to increase regionally and globally in conjunction with changing climate, anthropogenic activit

Recognizing the great potential of civil society organizations (CSOs) as drivers of socialchange, this study examines how CSOs’ work directed towards consumers—in this case, to make food consumption practices sustainable—could be analyzed and improved through insights in practice theory. This research scope adds to the sustainable consumption literature by shifting the lens from the rich body of s

Background: It is well known that a severe cell injury after exposure to ionizing radiation is the induction of DNA double-strand breaks (DSBs). After exposure, an early response to DSBs is the phosphorylation of the histone H2AX molecule regions adjacent to the DSBs, referred to as γ-H2AX foci. The γ-H2AX assay after external exposure is a good tool for investigating the link between the absorbed

Friction, wear, and emission performance strongly depend on the contact pressure and area at the interface of the pad and disc. The contact situation at the pad-to-disc interface can be explained by the formation and destruction of mesoscopic sized contact plateaus on the pad surface. Experimental studies report that the initial surface roughness of cermet-coated discs strongly affects friction, w

Novel oxygen-deficient double-perovskite type oxide Ba2NixCo2−xO6 was applied to produce O2/CO2 mixed stream gas for oxyfuel combustion application. A series of different Co concentration substituted Ba2NixCo2−xO6 was synthesized by an EDTA-citrate sol-gel combustion method. The oxygen carriers, Ba2Ni0.25Co1.75O6, Ba2Ni0.45Co1.55O6, Ba2Ni0.65Co1.35O6 and Ba2Ni0.85Co1.15O6 were c\characterized by s

Background: Familial colorectal cancer type X (FCCTX) is a phenotypically defined subset of hereditary colorectal cancer with unknown and potentially heterogeneous genetic aetiology. FCCTX has been characterized as a colorectal cancer-specific syndrome, which we herein challenge by estimating the risk for extra-colorectal cancer in the Danish FCCTX cohort. Methods: Through the national hereditary

Médecins Sans Frontières (MSF) does currently not have dedicated decision-making support for their in-country inventory allocation and is exploring how such decision support framework could be designed to enhance their supply chain operations. The purpose of this thesis is thus to develop a structured framework for country-level inventory allocation decision-making at MSF.To fulfil the purpose t

The selective separation of glycoproteins is essential in biomarker discovery, glycoprotein profiling and analysis. Glycosylation of proteins has a major impact on their structure and function. The heterogeneity of glycosylation patterns makes the glycomic profiling extensive, but nonetheless of upmost importance for the deeper understanding of metabolic pathways, cell signalling and the impact of
