Populärvetenskaplig sammanfattning: Kvävebelastningen på sjöar och hav har ökat markant de senaste tiotal åren. Jordbruket står för ca 50 % av de svenska kväveutsläppen som människan bidrar till. En ökad kvävebelastning på haven kan leda till övergödning, vilket får en stor negativ effekt på vattenekosystemen. Ett sätt att minska övergödningsproblematiken är att öka vattnets uppehållstid i landskaPolitical decisions have resulted in more focus on how to optimize wetlands natural ability to lower nitrogen fluxes in order to minimize the problem with eutrophication in costal areas. However there is no exact knowledge how to calculate the effectiveness of nitrogen removal in wetlands with natural water flow due to the many biochemical and hydrological processes that interact. In this study tw

Whether or not to allow socialisation between parents and children in out-of-home care presents a difficult ethical challenge for those social work professionals who need to make an assessment about what to do. In this as well as in other contexts, it is widely assumed that the principle of the best interest of the child (BIC) is both the legal and moral standard for decision-making for children.

The keystone species concept holds that certain members of an ecological community, despite their low abundance, exert disproportionately large effects on species diversity and composition. In microbial ecology, experimental validation of this concept has been limited because targeted removal of individual species remains technically challenging. Here, we developed a procedure to test the keystone

A search for decays of the Higgs boson into a Z boson and a light resonance, with a mass of 0.5–3.5 GeV, is performed using the full 140 fb−1 dataset of 13 TeV proton–proton collisions recorded by the ATLAS detector during LHC Run 2. Leptonic decays of the Z boson and hadronic decays of the light resonance are considered. The resonance can be interpreted as a J/ψ or ηc meson, an axion-like particl

A search for pair-production of vector-like leptons is presented, considering their decays into a third-generation Standard Model (SM) quark and a vector leptoquark (U1) as predicted by an ultraviolet-complete extension of the SM, referred to as the ‘4321’ model. Given the assumed decay of U1 into third-generation SM fermions, the final state can contain multiple τ-leptons and b-quarks. This searc

BACKGROUND AND PURPOSE: Surgical outcomes in patients with flexible adult-acquired flatfoot deformity (AAFD) have not been evaluated in large prospective register studies. Calcaneal osteotomy and hindfoot arthrodesis are commonly used. We aimed to compare the results of these 2 procedures using preoperative and 1-year postoperative patient-reported outcome data from the Swedish Quality Register fo

Understanding the structure-property relationship in electrocatalysts under working conditions is crucial for the rational design of novel and improved catalytic materials. This paper presents the Aarhus University reactor for electrochemical studies using X-rays (AUREX) operando electrocatalytic flow cell, designed as an easy-To-use versatile setup with a minimal background contribution and a uni

Background: Enabling women to make informed decisions is a key objective in the guidelines governing prenatal screening and diagnostics. Despite efforts to provide information, research shows that women's choice of prenatal screening is often not based on informed decisions. The aim of this study was to investigate pregnant women's perceptions of the use of an interactive web-based DA, developed t

There is a call for more analysis and case knowledge of how the media use the participatory architecture of social media in media production. The research field of audience participation comes from the integration of concepts and theories about an active audience with production research, and social and cultural theory. This thesis analyses cultural participation from the perspective of profession

Popular Abstract in Swedish Att bedöma välbefinnande hos patienter med mag/tarmcancer Avhandlingen handlar om undernäring, beroende/oberoende i det dagliga livet och uppfattningar om hälsorelaterad livskvalitet hos patienter som opereras pga cancer i mag/tarmkanalen. Enligt journaldokumentation hos 45 patienter som opererades 1985-89, för cancer i bukspottkörteln, hade patienterna ett försämrat nThe aim was to study some aspects of patients´ well-being, related to nutrition, activities of daily living and health related quality of life, when undergoing major gastrointestinal cancer surgery. Chart documentations (N=45) of patients undergoing subtotal pancreatectomy were studied, and showed the patients' well-being to be affected, although it was not possible to fully evaluate the results o

BACKGROUND & AIMS: Few modifiable risk factors have been implicated in the etiology of pancreatic cancer. There is little evidence for the effects of caffeinated coffee, decaffeinated coffee, or tea intake on risk of pancreatic cancer. We investigated the association of total coffee, caffeinated coffee, decaffeinated coffee, and tea consumption with risk of pancreatic cancer. METHODS: This stu

A search is presented for gluinos decaying via the supersymmetric partner of the top quark using events with two same-sign leptons, jets, and missing transverse momentum. The analysis is performed with 2: 05 fb(-1) of integrated luminosity from pp collisions at root s = 7 TeV collected by the ATLAS detector at the LHC. No excess beyond the standard model expectation is observed, and exclusion limi

This Letter presents the first search for a heavy particle decaying into an e(+/-)mu(-/+) final state in root s = 7 TeV pp collisions at the LHC. The data were recorded by the ATLAS detector during 2010 and correspond to a total integrated luminosity of 35 pb(-1). No excess above the standard model background expectation is observed. Exclusions at 95% confidence level are placed on two representat

A search is presented for new particles decaying to large numbers (7 or more) of jets, with missing transverse momentum and no isolated electrons or muons. This analysis uses 20.3 fb(-1) of p p collision data at root s = 8 TeV collected by the ATLAS experiment at the Large Hadron Collider. The sensitivity of the search is enhanced by considering the number of b-tagged jets and the scalar sum of ma

A measurement of spin correlation in tt[over ¯] production is presented using data collected with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at a center-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 20.3 fb^{-1}. The correlation between the top and antitop quark spins is extracted from dilepton tt[over ¯] events by using the difference in th

The effect of a single washing of the urogenital tract with 0.5 g/l chlorhexidine was studied in 6 women in weeks 38-40 of pregnancy, among whom 5 were carriers of group B streptococci in urethra and/or cervix. The chlorhexidine concentrations varied between 25 and 200 mg/l during the first hour after washing in 5 of the 6 women, whereas one patient showed concentrations below 25 mg/l. With the ex
