Membrane screening to identify optimal properties when separating organic matter from Bolmen water

Vilket membran lämpar sig bäst när det kommer till avskiljning av organiskt material från Bolmenvatten? Med vattendrag som blir brunare och brunare – hur ska våra dricksvattenverk klara av att säkra vårt vatten i framtiden? Svaret heter membranteknik! Vilket membran som passar bäst är däremot en svårare fråga att besvara och således också det som har undersökts i denna studie.In many places across the northern hemisphere, drinking water treatment plants (WTPs) need to avert the effects of deteriorating quality in surface water sources caused by increasing lev-els of natural organic matter (NOM). The two major factors responsible for this phenomenon, also called brownification, are the greenhouse effect and changes in soil acidification. Additional treatment steps needs

Lipid Micro Emboli in Cardiac Surgery

This thesis is based on five studies. It includes the characterization of lipid micro emboli in shed mediastinal blood during cardiac surgery. The reuse of blood directly by cardiotomy suction is a common practice in order to reduce the need of blood transfusions. In shed mediastinal blood we showed that there is an abundance of lipid particles in the size range of 10-60μm. These lipid particles a

Individual Placement and Support (IPS) for persons with severe mental illness -Outcomes of a randomised controlled trial in Sweden

Popular Abstract in Swedish Den arbetsrehabilitering som traditionellt erbjuds personer med psykisk funktionsnedsättning kan beskrivas som en trappa där varje steg består av olika åtgärder för att öka personernas arbetsförmåga. Målet är att personerna successivt skall bli friskare, öka sin funktionsnivå och utveckla fler färdigheter innan de kan ta steget ut till ett konkurrensutsatt arbete. För pIn the light of the limited research on the subject of Individual Placement and Support (IPS) in a Swedish context, this thesis has contributed with knowledge of the effectiveness and experiences of IPS among persons with severe mental illness (SMI) living in Sweden. The thesis has also provided information about the work motivation among those persons with SMI who seek vocational support by IPS.

Changing Landscapes and Persistent Places : An Exploration of the Bjäre Peninsula

Changing Landscapes and Persistent Places is a study of the cultural landscape on the Bjäre peninsula in northwest Skåne. The many Bronze Age remains that give the landscape its distinctive character are the starting point for an attempt to increase our understanding of the historical depth of today’s landscape. The two perspectives of “landscape” and “places” carry the discussion forward, almost

Investigations of temporal changes in climate and the geomagnetic field via high-resolution radiocarbon dating

Klimatet har varit relativt stabilt under den nuvarande interglaciala epoken (Holocen) som inleddes för ungefär 11 700 år sedan. Genom klimatrekonstruktioner från olika geologiska arkiv såsom iskärnor, sjösediment och torvmossar har det ändå påvisats att snabba förändringar i klimatet har inträffat under denna epok. En sådan tidsperiod inträffade för omkring 2800 år sedan och den är intressant ur Geological archives have shown periods of abrupt climate change in the relatively stable Holocene epoch (last ca. 11 700 years). One of these periods was around 2800 cal BP. Several records, mainly from Europe, reveal a shift towards wetter, cooler and windier conditions. There are, however, indications for a global extent of the climate change. The climate change coincides with a distinct increas

In-hospital bed occupancy and the emergency department - effects on decisions about the level of care

Popular Abstract in Swedish Bakgrund: Patientflödet genom en akutmottagning regleras framförallt av tre typer av faktorer. Dessa rör i tur och ordning inflödet-, genomflödet- och utflödet av patienter. Faktorer som reglerar inflödet rör efterfrågan på sjukvård (t.ex. samhällsdemografi och tillgång på primärvård), medan faktorer som reglerar genomflödet till största delen rör akutmottagningens inteBackground: Emergency Department (ED) overcrowding occurs when the need for ED services outstrips available resources. Causes have been divided into input, throughput, and output factors, of which the last appear to be the most influential. Unavailability of inpatient beds (so-called “access block,” or “hospital crowding”) impairs ED output and is associated with increased waiting times in the ED

Immunological and Inflammtory Responses against Intrastriatal Neural Grafts in the Rat

Intracerebral neural transplantation offers a new strategy to combat Parkinson’s and Huntington’s diseases. However, a host immune response against a histoincompatible neural graft in the brain may jeopardize transplant survival. We transplanted dissociated mesencephalic tissue prepared from Sprague-Dawley (SD) (syngeneic), Lewis (allogeneic) rats or mice (xenogeneic), into 6-hydroxydopamine (6-OH

Structural pathology and functional analysis of vitamin K-dependent protein S

Protein S deficiency is an autosomal dominant trait affecting around 10% of families thrombophilic families. The high affinity interaction of approximately 60% of protein S with C4b -binding protein (C4BP) has raised a complicated situation for the diagnosis of deficiency states. Because only free protein S functions as cofactor in the protein C anticoagulant, it is important to measure free prote

Leaching of Polycyclic Aromatic Hydrocarbons Using a Column Method

Popular Abstract in Swedish Polycykliska aromatiska kolväten (PAH) är en grupp organiska ämnen som kan vara giftiga men även starkt cancerframkallande. De bildas vid förbränning av organiskt material vid låg syretillförsel och återfinns i olika produkter som tjära och fossila bränslen. De källor som tillför störst mängd till miljön idag är bostadsuppvärmning med ved, kol och olja (i Sverige ca 2/3Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants of great environmental concern, due to their toxicity, carcinogenicity and long persistence in the environment. To determine the potential risk associated with PAHs released from contaminated soil or waste materials, knowledge is required on the leachable concentrations of PAHs and the amounts available for release. The obj

Roles of PDZ-dependent Interactions and N-glycosylation in G Protein-coupled Estrogen Receptor 1 (GPER1)/GPR30-mediated Stimulation of ERK1/2 Activity

G protein-coupled receptor 30 (GPR30) is a G protein-coupled receptor (GPCR) that is attracting considerable attention in breast cancer and cardiometabolic regulation. Following reports that GPR30 is required for some rapid estrogen responses, e.g. increased cAMP production and ERK1/2 activity, in estrogen receptor (ER)-negative cells, GPR30 was renamed G protein-coupled estrogen receptor 1 (GPER1

ACE-2 HILLCLOUD. An overview of the ACE-2 ground-based cloud experiment

The ACE-2 HILLCLOUD experiment was carried out on the island of Tenerife in June-July 1997 to investigate the interaction of the boundary layer aerosol with a hill cap cloud forming over a ridge to the north-east of the island. The cloud was used as a natural flow through reactor to investigate the dependence of the cloud microphysics and chemistry on the characteristics of the aerosols and trace

Predict with Confidence: Application of a Bayesian-Based Assimilation Framework to Optimise Wetland CH4 Emissions from a Terrestrial Ecosystem

Uncertainty in our calculations of a system reveals the limits of our knowledge. This limitation makes model representations of the Earth system challenging and our predictions less reliable. However, despite appearing chaotic and non-linear, a system always follows a deterministic trajectory, which can often be expressed probabilistically. Building on this concept, this thesis applies data assimi

Silver rings and marten skins : Contacts between the Volga Region and the Baltic in the early Viking Age

Viking Age silver is a useful tool for tracing various aspects of the society. Contact networks, trade organization, society structure, economic variation etc. This paper concentrates on the so-called Permian rings, which appear in Scandinavian silver hoards from Early Viking Age. Their main concentration is, however, in the regions west of the Ural Mountains in Russia. As the rings found in Russi

Comparison of four inverse modelling systems applied to the estimation of HFC-125, HFC-134a, and SF6 emissions over Europe

Hydrofluorocarbons (HFCs) are used in a range of industrial applications and have largely replaced previously used gases (CFCs and HCFCs). HFCs are not ozone-depleting but have large global warming potentials and are, therefore, reported to the United Nations Framework Convention on Climate Change (UNFCCC). Here, we use four independent inverse models to estimate European emissions of the two HFCs

Quality of Life in Patients with High-grade Non–muscle-invasive Bladder Cancer Undergoing Standard Versus Reduced Frequency of Bacillus Calmette-Guérin Instillations : The EAU-RF NIMBUS Trial

Background: Adverse events induced by intravesical bacillus Calmette-Guérin (BCG) to treat high-grade non–muscle-invasive bladder cancer (NMIBC) often lead to treatment discontinuation. The EAU-RF NIMBUS trial found a reduced number of standard-dose BCG instillations to be inferior with the standard regimen. Nonetheless, it remains important to evaluate whether patients in the reduced BCG treatmen

Involvement of voltage-dependent potassium channels in the EDHF-mediated relaxation of rat hepatic artery

1. In the rat hepatic artery, the acetylcholine-induced relaxation mediated by endothelium-derived hyperpolarizing factor (EDHF) is abolished by a combination of apamin and charybdotoxin, inhibitors of small (SK(Ca)) and large (BK(Ca)) conductance calcium-sensitive potassium (K)-channels, respectively, but not by each toxin alone. The selective BK(Ca) inhibitor iberiotoxin cannot replace charybdot

Broad-Scale Patterns in CDOM and Total Organic Matter Concentrations of Inland Waters – Insights from Remote Sensing and GIS

The rise in CDOM (coloured dissloved organic matter) is likely to be relatively more pronounced in remote northern regions. However, there is a lack of monitoring to confirm this. For this reason, there is a strong incentive to develop remote sensing-based methods to map CDOM in lakes across broader geographical scales and to include geograghic contex in such analysis. There is a lack of understan
