Floder och åar är viktiga källor för järn och andra näringsämnen till Östersjön. De senaste decennierna har järnkoncentrationen i svenska och finska åar ökat kraftigt, vilket skulle kunna leda till en ökad transport av järn till Östersjön. Vilken effekt detta kan ha för Östersjön beror på vad som händer med järnet när det möter det salta vattnet i Östersjön. Järn transporteras huvudsakligen i formRivers have traditionally not been considered important sources of bioavailable iron (Fe) to the marine waters, since most Fe is lost by salinity-induced aggregation and sedimentation during estuarine mixing. However, recent studies from boreal rivers found a remarkably high Fe stability, probably due to the interaction with organic matter. Recent studies have suggested that Fe speciation is a key

OBJECTIVE: To analyze the association between rheumatoid arthritis, systemic lupus erythematosus, and ankylosing spondylitis and hospitalization for psychiatric disorders, as well as the association between hospitalization for dementia or delirium and systemic lupus erythematosus, by using a novel, large-scale approach.DESIGN: Cohort study with follow-up between 1973 and 2004.PARTICIPANTS: The ent

BACKGROUND: The aim of this study was to investigate the possibility of using extended-wavelength diffuse reflectance spectroscopy (EW-DRS) to measure tissue response related to blood perfusion. The study was performed on a model that we have previously found to be useful for studying techniques for perfusion monitoring following the injection of epinephrine in a local anesthetic in the human fore

Industrial Symbiosis (IS) is a collective approach to competitive advantage in which separate industries create a cooperative network to exchange materials, energy, water and/or by-products. By addressing issues related to resource depletion, waste management and pollution, IS plays an important role in the transition towards sustainable development. In the literature, two conceptual perspectives

Magnetoliposomes (MLs) were synthesized and tested for longitudinal monitoring of transplanted pancreatic islets using magnetic resonance imaging (MRI) in rat models. The rat insulinoma cell line INS-1E and isolated pancreatic islets from outbred and inbred rats were used to optimize labeling conditions in vitro. Strong MRI contrast was generated by islets exposed to 50 µg Fe/ml for 24 hours witho

In the State of Oaxaca in Southern Mexico exist abundant natural resource and excellent wind conditions. Currently in the region of the Isthmus of Tehuantepec in Oaxaca has an extensive area with wind farm projects due to their excellent wind speed conditions. A large wind energy plant – the Project Mareña Renovables that since their origins started in 2004 with Preneal Company. It was planned to

Examensarbetet undersöker möjligheten att låta avbördningskapaciteten – det vill säga sambandet mellan vattennivå och vattenföring – vara vägledande för bedömning av underhållsbehovet i åar och diken. Den potentiella nyttan av en sådan metod bedöms vara hög då den skulle kunna minska frekvensen av omotiverade underhållsinsatser som påverkar vattenmiljön negativt. Arbetet utgår från ett dikningsförThis master thesis project investigates the possibility of using stage–discharge relationships for evaluation of river maintenance demands. In Sweden, the potential benefit of this type of methodology is considered high, in order to prevent unnecessary maintenance activities which are harmful for the aquatic environment. The study is focused on a ditching organization in Höje River in southern Swe

In the 2014 Swedish national election the Sweden Democrats, a radical right-wing and anti-immigrant party, established itself as the third biggest party and as an outcome, racism has become an everyday issue of the society. This can be seen everywhere, not least in educational settings where, for instance, insulting language use, violation of integrity, sexual harassment and hate crimes are common

Within the three key themes of Innovation & Design, Industry Relations, and Market Strategy, we have identified important factors for the survival of Apple as a niche player in a network economy. Concerning the theme of Innovation & Design the factors recognized are Radical Innovation, Resolving Schematic Incongruity, and Technological Evolution. Regarding Industry Relations we have found

The purpose of this thesis is to contribute to a further understanding of the complexity in green consumer behaviour by examining how and why individuals priorities values, personal norms and identity in green consumer behaviour. The thesis employs a qualitative approach with an abductive strategy. The empirical data was produced through in-depth interviews with green consumers. Based upon the emp

This thesis examines the evolution of Policy Coherence for Development (PCD) in the EU. The overarching purpose is to give an example of ideational causation in the EU, and concretely, to illustrate how a norm can cause changes to policy and to policymaking. It is argued that the PCD concept is essentially a norm, because it provides a guideline for how to prioritize between differing and often co

The pattern of endocrine disorders in long-term survivors of childhood cancer has not been investigated comprehensively. Here, we aimed to assess the lifetime risk of these disorders in Nordic survivors of childhood cancer.

The aim of this prospective substudy was to estimate the cost-effectiveness of treating paroxysmal atrial fibrillation (AF) with radiofrequency catheter ablation (RFA) compared with antiarrhythmic drugs (AADs) as first-line treatment.

For the amine transaminase (ATA)-catalyzed synthesis of chiral amines, the choice of donor substrate is of high importance for reaction and process design. Alanine was investigated as an amine donor for the reductive amination of a poorly water-soluble ketone (4-phenyl-2-butanone) in a combined in situ product removal (ISPR) approach using liquid-membrane extraction together with an enzyme cascade

Diamond-Blackfan anemia (DBA) is a congenital erythroid hypoplasia caused by haploinsufficiency of genes encoding ribosomal proteins (RPs). Perturbed ribosome biogenesis in DBA has been shown to induce a p53-mediated ribosomal stress response. However, the mechanisms of p53 activation and its relevance for the erythroid defect remain elusive. Previous studies have indicated that activation of p53

The potential effects of altering primary settlers during biological in-line hydrolysis and converting a nitrifying activated sludge process into a partial pre-denitrification process for the purpose of resource conservation were evaluated. A full-scale primary sludge hydrolysis experiment was performed at a wastewater treatment plant and implemented in a dynamic modelling tool based on ASM2d. The

To investigate and describe the content, dissemination and effects of case management interventions for informal caregivers of older adults, focusing on outcomes related to patients' activities of daily living, nutrition assessment, pain measurement, depression, length of stay and to caregivers' satisfaction and difficulties.

At least 17 genomic regions are established as harboring melanoma susceptibility variants, in most instances with genome-wide levels of significance and replication in independent samples. Based on genome-wide single nucleotide polymorphism (SNP) data augmented by imputation to the 1,000 Genomes reference panel, we have fine mapped these regions in over 5,000 individuals with melanoma (mainly from

L-DOPA is the gold-standard treatment for Parkinson's disease (PD), but induces troublesome dyskinesia after prolonged treatment. This is associated with the 'false neurotransmitter' conversion of L-DOPA to dopamine by serotonin neurons projecting from the raphe to the dorsal striatum. Reducing their activity by targeting pre-synaptic 5-HT1A receptors should thus be an attractive therapeutic strat
