We investigated the occurrence of microplastics (size range 5,000-50 µm) in leach-ates at 11 landfills of different age and operational status in Finland, Iceland and Nor-way. Collective sampling was carried out by pumping leachate with a stainless-steel submergible pump through a custom-made, stainless-steel filter unit containing filter plates with decreasing pore sizes (5,000, 417 and 47 µm, re
Flerovium (Fl, element 114) is the heaviest element chemically studied so far. To date, its interaction with gold was investigated in two gas-solid chromatography experiments, which reported two different types of interaction, however, each based on the level of a few registered atoms only. Whereas noble-gas-like properties were suggested from the first experiment, the second one pointed at a vola
Background: Traumatic brain injury (TBI) is a common injury and constitutes up to 3% of emergency department (ED) visits. Current studies show that TBI is most commonly inflicted in older patients after ground-level falls. These patients often take medications affecting coagulation such as anticoagulants or antiplatelet drugs. Guidelines for ED TBI-management assume that anticoagulation therapy (A
För att se om antalet D-interaktioner kunde minskas skickades information om interaktioner på individnivå till vårdcentraler.Allmänläkarna ombads att utifrån medföljande rekommendationer ompröva behandlingen och besvara en enkät.Mindre än hälften av D-interaktionerna berodde på medvetna ordinationsval.Mer än hälften av interaktionerna hade uppkommit det senaste året, trots tydlig varning vid ordinDuring 2012, one Swedish national goal for better health for elderly was to decrease drug-drug interactions. We performed an intervention, where the physicians in primary health care were alerted to which of their patients had a drug-drug interaction. The physicians received a letter with patient information and recommendations on how to act. They were requested to review if the interactions still
Purpose: This work reports for the first time on the implementation and application of cardiac diffusion-weighted MRI on a Connectom MR scanner with a maximum gradient strength of 300 mT/m. It evaluates the benefits of the increased gradient performance for the investigation of the myocardial microstructure. Methods: Cardiac diffusion-weighted imaging (DWI) experiments were performed on 10 healthy
BACKGROUND: In patients with a degenerative tear of the medial meniscus, recent meta-analyses and systematic reviews have shown no treatment benefit of arthroscopic partial meniscectomy (APM) over conservative treatment or placebo surgery. Yet, advocates of APM still argue that APM is cost effective. Giving advocates of APM their due, we note that there is evidence from the treatment of other musc
When it comes to the mathematical modelling of social interaction patterns, a number of different models have emerged and been studied over the last decade, in which individuals randomly interact on the basis of an underlying graph structure and share their opinions. A prominent example of the so-called bounded confidence models is the one introduced by Deffuant et al.: Two neighboring individuals
Background The efficacy of the interception and purification mechanism for low-dose toxic contaminants in riverbeds, which serve as a link between surface water and groundwater, is of paramount importance in ensuring groundwater safety, particularly considering the replenishment of reclaimed water. The specific objective of this work is to identify the variation of interception efficiency and tran
We have studied the interaction of light with an array of vertically oriented III-V semiconductor nanowires both theoretically and experimentally. For the theoretical studies, electromagnetic modeling has been employed. This modeling shows that with proper tuning of the nanowire diameter, the absorption per volume semiconductor material can be 20 times higher in the nanowires than in a correspondi
Particle image velocimetry measurements are performed in a channel with periodic ribs on one wall. We investigate the flow around two different rib configurations: solid and perforated ribs with a slit. The ribs obstruct the channel by 20% of its height and are arranged 10 rib heights apart. For the perforated ribs, the slit height is 20% of the rib height, and the open-area ratio is 16%. We discu
Extrasolar planets are found to be on orbits very different from those of the planets in the solar system. Gas-giant planets have been found on orbits tighter than that of the planet Mercury, often with very high eccentricities. These orbits are surprising; models of planet formation suggest that gas giants should be found on circular orbits with similar size to those of solar-system gas giants.
This essay discusses the Nordic region Bohuslän the decade after it became "Swedish" in 1658, during what I call the region's "transition period". The wide cause of the study is to show how the traditional understanding of this state shift (and of state shifts in general) need to be problemized and understood in the light of the state conditions of Early Modern Europe. By e
This study investigates the presence of behavioral biases among cryptocurrency investors in Sweden and examines whether differences exist between males and females. Specifically, the behavioral biases of herding effect, conservatism, prospect theory, availability bias, and overconfidence are analyzed. The study employs four regressions in the statistical software Stata, with the presence of each b
The aim of this study was to analyze how preschool principals talk about their obligation to report child maltreatment to social services. Five principals, from five different local areas, were interviewed in the study. Two of the preschools were situated in underprivileged areas, and the others in economically and socially fairly well situated areas. Discourse analysis was applied in the examinat
Uppsatsen undersöker hur DNA-bevisning bör värderas i mål om vapenbrott där försvaret gör gällande att den tilltalades DNA överförts till vapnet genom sekundär överföring, det vill säga via en mellanhand snarare än genom direkt beröring. Syftet är att konstruera logiskt riktiga argumentationsstrukturer med hjälp av bayesianska nätverk, samt att belysa den bayesianska metodens möjligheter och begräThis thesis examines how DNA evidence should be evaluated in cases concerning firearms offences where the defence contends that the defendant's DNA was transferred to the weapon through secondary transfer that is, via an intermediary rather than through direct contact. The aim is to construct logically sound argumentative structures using Bayesian networks, and to shed light on the possibiliti
This thesis presents the results of an evaluation of the performance and determinants of fund flows for selected Impact Investing and Socially Responsible Investing portfolios of funds. The impact of current and past measures of monthly and annual financial return are considered from the perspective of potential investors. The results show that Impact Investing funds out-performed general market v
The engineers at Westinghouse Electric Company have developed a new nuclear fuel design called TRITON11™, which will be used in Boiling Water Reactors (BWR). This project has been to develop a test program and an assembly fixture for TRITON11™. The test program can not be fully presented in this repport due to confidentiality. The test program is for the first scoping test that will be performed o
