Context. The Gaia-ESO Survey (GES) is a large public spectroscopic survey at the European Southern Observatory Very Large Telescope. Aims. A key aim is to provide precise radial velocities (RVs) and projected equatorial velocities (v sin i) for representative samples of Galactic stars, which will complement information obtained by the Gaia astrometry satellite. Methods. We present an analysis to e
A pilot plant was set up to treat leachate from an industrial landfill containing shredder residues of end-of-life vehicles and white goods. The treatment plant consisted of aeration and sedimentation steps for pre-treatment, and a filter. The plant was designed to simultaneously remove various types of pollutants. The efficiencies of pre-treatment and of the main treatment step were investigated
Tuvalu, a low-lying Small Island Developing State (SIDS), is projected to face severe challenges due to climate change. Most notably, permanent inundation or the permanent loss of habitable land due to sea-level rise. This thesis investigates how Tuvalu has framed climate change as an existential security threat in its international discourse from 2021 to 2023. Applying an adapted version of secur
This work explores the catalytic activity of decavanadate (V10)-based catalysts in the selective oxidation of ethylbenzene (EB), a model compound of lignin-derived molecules, under mild conditions. The goal is to assess the catalytic efficiency, product selectivity, and the influence of counter-ions on activity through systematic testing of parameters such as temperature and catalyst loading. Addi
Prehistorical musical instruments have been explored in archaeology more systematically since the 1970s when music archaeology was established as a field of study. The new awareness initially led to studies centred on retrieving musical instruments that had been missed and were now lost in archives. New discoveries, too, are very object-oriented. This master’s thesis ties together individual finds
Moderate exercise is deemed beneficial for cognition due to increase in dopamine concentrations in the basal ganglia. Auditory white noise is beneficial for cognition, mainly for those with lower attentional ability, i.e. for those having lower tonic dopamine concentrations. For individuals with higher attention ability white noise can have a negative effect. In this thesis it was examined whether
All vårdpersonal bör ges grundläggande kunskaper om smärtsinnet, reaktioner på smärta samt behandling av olika typer av smärta. Sjuksköterskor ska dessutom ha god kännedom om tekniker för smärtskattning, om psykologiska faktorers betydelse och om traditionella smärtstillande läkemedels kliniska användning (SoS-rapport 1994:4). Syftet med denna studie var att undersöka förekomst, innehåll och mål f
Bristande handhygien inom vården är ett globalt problem och det finns ett samband mellan låg följsamhet av rutiner för handhygien och förekomsten av vårdrelaterade infektioner. Syftet med denna studie var att undersöka sjuksköterskors syn på orsaker till bristande handhygien samt vilka möjligheter som finns för förbättringar. För att undersöka detta användes ett frågeformulär med öppna frågor som
It is described in the preparatory work of the Social Services Act that a reasonable standard of living should be based on the prevailing conditions under which the individual lives. Because there is no specified description of the phrase, this entails interpretability of the phrase and therefore uncertainty about what it infers. The purpose of this study is to analyse the representation of the ph
This paper empirically investigates the relationship between industrial ownership and environmental degradation in the People’s Republic of China, with specific focus on two environmental indicators: volume of SO2 emissions and volume of industrial wastewater deemed unsafe for discharge. Sulfur dioxide and untreated wastewater emissions are considered some of the most problematic environmental and
This research investigated the liquid-phase removal of chloramphenicol (CAP), an emerging contaminant using molecularly imprinted polymers (MIPs). CAP adsorption profiles, equilibrium, and kinetics were analysed. The adsorption performance was compared between MIPs and non-imprinted polymers (NIPs), both with silica or without silica grafting. The imprinting factor (IF) values for the Si@MIPs-CAP
In Ethiopia, full vaccination coverage among children aged 12–23 months has improved in recent decades. This study aimed to investigate drivers of the improvement in the vaccination coverage. The Oaxaca–Blinder decomposition technique was applied to identify the drivers using data from Ethiopian Demographic and Health Survey conducted in 2000 and 2016. The vaccination coverage rose from 14.3% in 2
Proton exchange membrane fuel cells (PEMFCs) are regarded as alternative energy sources because they are environment friendly and deliver no harmful emission. As its reliability and power generating efficiency is largely influenced by the temperature distribution, it is necessary to improve the temperature uniformity which is crucial in PEMFCs. To this end, this numerical study presents an attempt
Abstract Background: Advanced paediatric surgery is increasingly centralised in Sweden in order to improve treatment outcomes and reduce surgical risks. However, the overall need for surgery in the paediatric population has not been estimated, and the association between geographic access to surgical facilities and timely treatment for common surgical conditions in children is largely unknown.
Increasing loading of terrestrially derived dissolved organic matter tends to enhance bacterioplankton respiration (BR) in boreal estuaries, but knowledge on the mechanisms behind this effect is not complete. We determined the stable isotopic signature of the reactive estuarine dissolved organic carbon (DOC) in the Öre estuary (Baltic Sea) by using the Keeling plot method. The δ13C ratio of the es
