Micropollutant removal is a key component of the revised Urban Wastewater Treatment Directive (UWWTD) and can be achieved with ozonation. During ozonation, the composition of the wastewater matrix and the targeted treatment level for individual micropollutants or groups of such compounds affect ozone consumption. In this work, it was hypothesized that nitrite scavenging, the point of dosing (befor
A search for T and Y vector-like quarks produced in proton-proton collisions at a centre-of-mass energy of 13 TeV and decaying into Wb in the fully hadronic final state is presented. The search uses 139 fb−1 of data collected by the ATLAS detector at the LHC from 2015 to 2018. The final state is characterised by a hadronically decaying W boson with large Lorentz boost and a b-tagged jet, which are
Hydraulic balancing is key to ensure proper operation of the heating system. When the heating system is not hydraulically balanced, heat is unevenly distributed across dwellings resulting in a wide temperature spread, overheating, and consequently, wastage of energy. In this paper, we study to which extent hydraulic imbalance affects the thermal energy demand of buildings. Furthermore, key variabl
Since treatment for latent cryptococcal infection (CI) before starting antiretroviral therapy (ART) reduces mortality in HIV-infected subjects, screening for cryptococcal antigen (CrAg) in blood is recommended for individuals with CD4 cell counts < 100 cells/µL in regions with high CI prevalence. We assessed CrAg screening using the lateral flow assay in HIV-infected adults eligible for ART in cen
Aim. The aim of this study is to examine associations between caregiver burden, perceived health and sense of coherence in family caregivers to persons with dementia living at home. Background. Most of the studies on family caregivers have focused on burden and morbidity. However, the caregiver's sense of coherence and perceived health have not been studied earlier in relation to caregiver burden.
Exoplanets have been observed at many stages of their host star's life, including the main-sequence (MS), subgiant and red giant branch stages. Also, polluted white dwarfs (WDs) likely represent dynamically active systems at late times. Here, we perform three-body simulations which include realistic post-MS stellar mass-loss and span the entire lifetime of exosystems with two massive planets, from
It has been proposed that the EU Ecodesign Directive can promote resource efficiency through relevant ecodesign requirements. This paper examines the potential for rare earth element (REE) resource efficiency improvements in the event the current regulation for electric motors under the Ecodesign Directive is to be extended to comprise REE-based permanent magnet motors. The research is based on li
Historical demography, which is the study of human population dynamics in the past, is central for understanding human behaviours and traits, such as fertility, mortality and migration. An important factor in demographic research is the geographic context. Where people lived often determined their social ties, exposure to diseases and economic development. Such information is essential not only fo
Alltsedan det kalla kriget slutade har försvarssektorn, framförallt militär logistik och försvarsmaterielanskaffning, genomgått en genomgripande transformation. Flera faktorer har bidragit till transformationen: förändringar i länders och organisationers försvars- och säkerhetspolitik; reducerade försvarsbudgetar; deltagande i fredsbevarande och fredsframtvingande operationer; erfarenheter från deSince the ending of the Cold War, the defence sector, particularly the areas of military logistics and defence acquisition, has been undergoing a comprehensive transformation. There are several factors that explain this transformation: changes in defence and security policies for nations and organisations; reductions in defence expenditure; participation in Peace Support Operations; Lessons Learne
Popular Abstract in Swedish Det är sedan länge känt att för samma bildkvalitet kan patientstråldosen variera kraftigt mellan två olika sjukhus för en och samma röntgenundersökning. Det finns ett stort utrymme för sänkning av patientstråldosen utan att undersökningens kvalitet påverkas. Vid optimering inom röntgendiagnostik balanseras patientstråldos mot bildkvalitet. Optimeringen kräver att man haOptimisation in diagnostic radiology requires accurate methods for determination of patient absorbed dose and clinical image quality. Simple methods for evaluation of clinical image quality are at present scarce and this project aims at developing such methods. Two methods are used and further developed; fulfilment of image criteria (IC) and visual grading analysis (VGA). Clinical image quality de
Three titania polymorphs, anatase, rutile, and TiO2(B), were used as supports for vanadia. Catalysts with nominal loadings corresponding to 1.5 and 5 theoretical layers were prepared. True monolayer samples were obtained by NH3(aq)-treatment of the samples with 5 nominal vanadia layers. Prepared catalysts were characterized by chemical analysis, ESR, and high-resolution electron microscopy. It was
This book chapter discusses and evaluates four different efforts to extend human life: Normalize ageing, Optimize ageing, Retard ageing and postpone death, and Eliminate or overcome ageing and death. I suggest that improved treatment of disease and handicap at all ages should be welcomed. As a secondary effect, this may in many cases result in an extension of individual lives. However, the direct
This thesis presents investigations for the improvement of electrical contact and catalytical properties of two fungal redox enzymes, cellobiose dehydrogenase (CDH) and pyranose dehydrogenase (PDH), with electrodes and the use of the prepared electrodes as carbohydrate biosensors and in enzymatic biofuel cells. The performance of enzyme modified electrodes can be improved in two ways, by modifying
