A method for simultaneous determination of 5-hydroxy-N-methyl-2-pyrrolidone (5-HNMP) and 2-hydroxy-N-methylsuccinimide (2-HMSI) was developed. These compounds are metabolites from N-methyl-2-pyrrolidone (NMP), a powerful and widely used organic solvent. 5-HNMP and 2-HMSI were purified from plasma and urine by solid-phase extraction using Isolute ENV+ columns, and analysed by liquid chromatography
Det finns många typer av säkerhetsstudier. En av dessa är en så kallad konfliktstudie. När man idag gör en traditionell konfliktstudie analyserar man trafiksäkerheten, oftast utifrån video-data. Det vill säga en observering av den verkliga situationen. En traditionell konfliktstudie har gjorts av Svensson & Ekblad, (2018) på en korsning vid Heleneholmsstigen/Ystadvägen i Malmö där man byggt omThere are many types of traffic studies. One of these is a so-called conflict study. Today when you do a traditional conflict study, you usually analyze traffic safety based on video data, which is an observation of the real situation. A traditional conflict study was made by Svensson & Ekblad, (2018) at a crossing at Heleneholmsstigen/Ystadvägen in Malmö, where a bicycle crossing was rebuilt.
This paper aims to analyze individuals’ perceptions of artificial intelligence (AI) and how they perceive the potential risks and benefits of AI. This study examines how information treatment effects change people’s attitudes toward AI. To analyze this, an experimental survey was conducted on April 27, 2023. A total of 120 respondents were obtained through the research platform Prolific and after
The objective of this essay is to examine the relationship between Environmental, Social and Governance (ESG) and abnormal returns for companies in six different industries: Consumer Goods, Financials, Health Care, Industrials, Technology and Utilities. In order to investigate this topic, we construct equally weighted high minus low (HML) portfolios for every individual ESG pillar and for ESG as a
Bakgrund: Sveriges invandring har förändrats över tid och vi möter allt fler människor som är födda i ett annat land. För att kunna hjälpa dem som invandrar till Sverige idag är det viktigt att veta hur de som varit här ett tag upplever sin vardag. Det kan antas att det finns en risk för att invandrares delaktighet och möjlighet till aktivitet blir begränsad då de inte längre befinner sig i sin no
Popular summary Estuarine eutrophication, the systemic limitation of oxygen in a body of water, has been increasingly monitored and scrutinized as an environmental concern needing acute and long term remediation efforts. The roots of eutrophication are largely attributed to anthropic sources within the watershed, sources that are products of modern civilization; such as agricultural and urban poll
Background: The Out of Africa hypothesis, OOAH, was challenged recently in an extended mtDNA analysis, PPA (Progressive Phylogenetic Analysis), that identified the African human populations as paraphyletic, a finding that contradicted the common OOAH understanding that Hss had originated in Africa and invaded Eurasia from there. The results were consistent with the molecular Out of Eurasia hypothe
The thesis studies the use of cloud native software and platforms to implement critical closed loop control. It considers technologies that provide low latency and reliable wireless communication, in terms of edge clouds and massive MIMO, but also approaches industrial IoT and the services of a distributed cloud, as an extension of commercial-of-the-shelf software and systems.First, the thesis def
Background: The predictive effects of change patterns of sleep problems on mental health after a long-term disaster remain poorly known. We examined the change patterns of sleep problems after the Wenchuan earthquake, and tested whether specific sleep-related change patterns could predict mental health problems (posttraumatic stress disorder [PTSD], anxiety, and depression) in the 10 years after W
The performance of timber in exposed environments is affected by several biotic and abiotic factors. For timber cladding and decking, two important aspects include reduced structural performance due to fungal decay and aesthetical changes resulting from superficial effects such as photodegradation and moulds. Predicting the long-term performance of timber is important because it enables rational m
This report compiles the findings of two business experiment surveys, conducted under CIRCUSOL Task 2.4. The experiments investigated customer preferences for two relatively novel market segments for circular photovoltaics, specifically (1) solar-powered charging stations for shared micro-mobility services, and (2) PV-systems for home-charging of electric vehicles. The experiments used the method
Achieving high performance face recognition often requires large manually labeled training datasets. As such datasets can be difficult to obtain, we investigate whether smaller datasets can be augmented synthetically in order to increase performance. We use 3D morphable models to create 3D reconstructions of faces from only a single image. The 3D reconstructions are used to render new face images
There is an increased interest not only in sustainability but also in becoming socially responsible due to greater awareness as well as pressure from stakeholders. Contradictive results are found on whether Socially Responsible Investments (SRIs) in the area of funds are outperforming conventional funds. Further, in the area of Mergers and Acquisitions (M&As), there is plenty of research ident
The purpose of this study was to examine how social workers working with people selling sexual services perceive the purpose, effects, and normative function of the Swedish Sex Purchase Law. The study is based on six semi-structured qualitative interviews with (social workers from the field). Theories that were used to analyse the data were social constructivism, radical feminism, and liberal femi
