Mercury is a hazardous environmental pollutant mobilized from natural sources, and anthropogenically contaminated and disturbed areas. Current methods to assess mobility and environmental impact are mainly based on field measurements, soil monitoring, and kinetic modelling. In order to understand in detail the extent to which different mineral sources can give rise to mercury release it is necessa

This paper focuses on challenges in implementation of research in community-based occupational therapy practice. Based on a two-year project in a south Swedish municipality aiming at studying implementation of structured assessment procedures in the housing adaptation process, the first purpose is to provide a detailed project description, and the second is to report on first results identifying c

Soil chemistry under the Solling clean-rain roof was simulated using the dynamic multi-layer soil chemistry model SAFE, including sulfate adsorption. Soil was sampled in order to parameterize the pH and sulfate concentration dependent sulfate adsorption isotherm used in SAFE. Modeled soil solution chemistry was compared to the 14 year long time-series of monthly measurements of soil solution data

In her widely cited and criticised Gender trouble, Judith Butler (1990) elaborated the thought that gender needs to be understood as performative – a certain kind of doing behind the bars of a hegemonic heterosexual imperative that governs intelligible bodily configurations. Drawing mainly on psychoanalytical and foucauldian arguments, Butler dwells upon numerous important questions concerning pow

The theme throughout this book is the buildning up of a new societal structure and the conflicts encompassed in such a project. I discuss the societal changes in Sandinista Nicaragua by way of placing the revolution in a historic, political, and social context. Throughout the work process it became increasingly clear that the conflicts of the FSLN were in principal due to two factors. First, the F

In order for an agent to achieve its objectives, make sound decisions, communicate and collaborate with others effectively it must have high quality representations. Representations can encapsulate objects, situations, experiences, decisions and behavior just to name a few. Our interest is in designing high quality representations, therefore it makes sense to ask of any representation; what does i

This paper studies three different frequency controllers and their effects on the voltage disturbance ride-through capability of a VSC-HVDC supplied industrial system. The idea of implementing frequency controller is to improve the power quality of industrial plants by slightly decreasing the VSC output voltage frequency since industrial processes are more sensitive to voltage drops than frequency

The adsorption of monocarboxylates (acetate, benzoate, and cyclohexanecarboxylate) at the water/goethite interface was studied as a function of pH and ionic strength by means of quantitative adsorption measurements and attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy. ATR-FTIR spectra were obtained of suspensions prepared in both H2O and D2O. In order to identify the

Background: The aim of this study was to determine whether relative qualitative and quantitative differences in protein expression could be related to smoke exposure or smoke-induced airway inflammation. We therefore explored and characterized the protein components found in bronchoalveolar lavage (BAL) fluid sampled from either lifelong smokers or never-smokers. Methods: BAL fluid samples obtaine

Aims: The indigenous flora of freshly chilled cold-smoked salmon just after the vacuum packaging, and the spoilage flora after storage, in vacuum package at 7 degrees C for 19 days, were to be investigated with two different sampling strategies. Methods and Results: Identification was performed using 16S rRNA sequencing of both isolated bacteria and bacterial DNA from tissue extract. The indigenou

UV/TiO2/H2O2, UV/TiO2 and UV/H2O2 were compared as pre-treatment processes for the detoxification of mixtures of 4-chlorophenol (4CP), 2,4-dichlorophenol (DCP), 2,4,6-trichlorophenol (TCP) and pentachlorophenol (PCP) prior to their biological treatment. When each chlorophenol was initially supplied at 50mg l(-1),UV/TiO2/H2O2 treatment supported the highest pollutant removal, COD removal, and dechl

The ontogenetic development of size heterogeneity and aggression was monitored in commercial culture tanks of yellowtail kingfish (Seriola lalandi Valenciennes). Size heterogeneity increased substantially with the introduction of Artemia as a food source at 12 days post-hatch (DPH), and was correlated with the appearance of aiming behaviour, a precursor to more direct aggressive interactions. Chas

Popular Abstract in Swedish Bildning, bearbetning och upplagring av cathepsin G, proteinas 3 och azurocidin - närbesläktade bakteriedödande proteiner i vita blodkroppar Människans kropp utsätts dagligen för fientliga attacker av olika sorters mikroorganismer, tillhörande bakterie-, virus- eller svampsläktet. Så länge vi är friska och vårt immunförsvar fungerar, kan vi som tur är framgångsrikt fö

The paper reports a project conducted within the framework of the National Library of Sweden's Expert Group on Library Statistics. The project is financed by the National Library of Sweden, and it aims to capture how library managements make use of the current library statistics (based on the ISO-standard) in the decision-making process. Questions are also asked about the quality and usefulness of

Genes encoding the DNA helicase TWINKLE (C10orf2) or the two subunits of mtDNA polymerase γ (POLγ) (POLG1 and POLG2) have a direct effect on the mitochondrial DNA replication machinery and were reported in many mitochondrial disorders. Friedreich's ataxia (FRDA) is the common cause of ataxia often associated with the expansion of a GAA repeat in intron 1 of the frataxin gene (FXN). Mitochondrial D

Thin ion transmission detectors can be used as a part of a telescope detector for mass and energy identification but also as a pre-cell detector in a microbeam system for studies of biological effects from single ion hits on individual living cells. We investigated a structure of graphene on silicon carbide (SiC) with the purpose to explore a thin transmission detector with a very low noise level

The HOO radical is a key intermediate in the atmosphere and is involved in a large number of reactions, including ozone loss cycles in the stratosphere and oxidation processes in the troposphere. This theses is a study of the HOO radical and its interactions with a number of small molecules that are present in the atmosphere. The HOO complexes were formed on the surface of growing argon matrices

Popular Abstract in Swedish Abstract Hydrogen embrittlement is a degradation process of mechanical/tribological properties (toughness, wear etc.) of mating steel surfaces. This is caused by the presence and interaction of hydrogen with applied stresses. Therefore, it is important to quantify the hydrogen content which could be dissolved under applied stresses in steel.
