The steel company SSAB in Borlänge has five plate heat exchangers that they use to cool the process water. The water is used to cool the steel after hot rolling. The exchangers need to be cleaned sometimes because of fouling, that reduces the cooling efficiency. This results in higher energy use and higher costs in the end. The goal of this paper is to create a model of a plate heat exchanger to m
In this paper we will investigate whether the ethnic composition of a county affects their trust. More specifically we will answer the question: does the ethnic composition affect the level of trust in Sweden and are there any specific factors that increase this effect? In order to do this we use data on Swedish citizens from the year 2001 to the year 2012. As an approximation for ethnicity we use
This report describes the design and development of weather shield concepts for wall-mounted fixed dome surveillance cameras. The aim was to create concepts that would have better functionality against rain than current solutions while at the same time being attractive, non-obtrusive products. During the first phase the challenges of a weather shield were explored in detail. Areas such as differe
Den statliga lönegarantin är en skyddslagstiftning som ger arbetstagare rätt till ersättning om arbetsgivaren går i konkurs. I en granskande rapport från Riksrevisionen framkommer det att 6–9 % av utbetalt garantibelopp utgörs av misstänkt missbruk av lönegarantin. Uppsatsens syfte är att undersöka om de föreslagna åtgärderna i Riksrevisionens granskning kan förväntas minska missbruk av lönegarantThe earnings guarantee is a legislation designated to compensate employees for loss of salary if the employer is declared bankrupt. In an audit by the Swedish National Audit Organization (the Swedish NAO), it is estimated that 6–9 % of all earnings guarantee payments consist of misusage. The purpose of this article is to examine if the measures suggested by the Swedish NAO can be considered adequa
This is the story if a beginning, a beginning of a journey to the unknown, to find my own path, because paths are made by walking...but you have to do the scariest part: start to walk. The project is presented as a handbook for the next generations of students that want to start their own office, answering the same questions and difficulties that I had during my trip. The idea of this Master pro
Häktning och restriktioner anses vara de mest ingripande personella tvångsmedel som kan användas mot den misstänkte. Det anses nödvändigt att åklagaren under förundersökning och brottmålsprocessen kan använda sig av straffprocessuella tvångsmedel för att lösa brott. Här skapas en spänning mellan statens möjligheter till effektiv brottsutredning och den enskildes krav på att tvångsåtgärder inte tilDetention and restrictions are the most coercive measures that can affect the suspect. It is considered necessary that the prosecutor during preliminary investigation and criminal trial procedure can use coercive measures to solve crimes. Here emerges a tension between the state´s opportunities to effective criminal investigation and the individual’s requirements that coercive measures are not app
Research on InterStellar Objects (ISOs) has been done for several decades, however, the first observed ISO in the Solar system was only recently discovered in 2017. It was named 1I/'Oumuamua and was only passing though the Solar system, but this may not be the case for all objects of its kind. For instance, one could gain a bound orbit around the Sun if the right amount of nudge is acquired wh
In the current study, the aim was to investigate whether attentional bias—an automatic and nonconscious pre-attentive process of filtering sensory information for emotional relevance—could be induced in normal students, by manipulating levels of stress. In a within-subject experimental design where each participant completed 3 word search puzzles, it was predicted that the ratio at which participa
As the capacity of solar photovoltaic (PV) panels installed around the world increases every year, so does the concern regarding their proper end-of-life management given the hazardous nature of this waste. European Member States such as Germany, Italy and Spain, being amongst the earliest adopters of this technology, have already started seeing end-of-life PV modules coming into the waste streams
Försörjningssektorn innefattar verksamheter som är verksamma inom områden som el, energi, vatten, posttjänster, viss mineralutvinning etcetera. När dessa verksamheter behöver införskaffa tjänster, varor och byggentreprenader, måste de göra det via ett upphandlingsförfarande, detta förfarande regleras i LUF. Detta gäller privata såväl som offentliga verksamhetsutövare. Syftet med denna uppsats ärEntities operation in sectors related to water, energy, transport and postal services and some forms of natural resource extraction need to go through a procurement-process when they need to procure services, wares, and construction contracts. In Swedish law this procurement-process is regulated by LUF. Private as well as government entities are both required to abide by LUF, even if the rules som
This thesis investigates how queer people perceive queer representations in popular media (film and TV) produced in recent years and how such representations affect queer people’s identity and self-perception, as well as how they mirror and reproduce heteronormative understandings of queerness. A cultural comparison between Czechia and Sweden in perceptions of heteronormativity and queer represent
In the past decade, there has been a major shift in automotive propulsion systems from fossil fuel vehicles to environmentally friendly, zero-emission transportation. This has made hydrogen-powered vehicles a hot topic. Volvo Group has launched a fuel cell truck to promote energy transition. A fuel cell consists of two electrodes (anode and cathode) and an electrolyte membrane inserted between the
Genrepedagogikens genomslag i en digitaliserad skola innebär att skrivundervisningens lärresurser i hög grad utgörs av olika typer av modelltexter. Läromedelsutredningen (SOU 2021:70) utförd på uppdrag av regeringen synliggör en spänning mellan den fysiska läroboken och alternativa undervisningsmaterial, men också att forskningen om hur lärresurser används i Sverige är begränsad. Syftet med denna Teaching and Learning Resources in Genre Pedagogy – The Role of Teaching and Learning Materials in the Development of Students’ Non-Fiction Writing Skills The impact of genre pedagogy in a digitalised school means that the resources for teaching writing are largely made up of different types of model texts. Läromedelsutredningen (SOU 2021:70) carried out on behalf of the government highlights a t
I och med införandet av ICD-11, 2018, tillkom diagnosen Komplex PTSD (C- PTSD) i den internationella klassifikationen av sjukdomar och Socialstyrelsen arbetar just nu med den svenska översättningen som förväntas publiceras någon gång under 2025 på WHO:s plattform. Syftet med denna studie var att undersöka hur kunskapsläget bland behandlare med lägst steg 1-kompetens såg ut inom vuxenpsykiatrin. DeSince the introduction of ICD-11 in 2018, C-PTSD has been a diagnosis in the international classification of diseases. Socialstyrelsen is currently working on the Swedish translation, which is expected to be published sometime in 2025. However, C-PTSD as a concept, has been around longer than that. The aim of this study has been to examine the level of knowledge regarding C-PTSD among clinicians,
Purpose of the study: This interdisciplinary study aims to explore the emerging and increasingly relevant field of best practices for stakeholder engagement, within a public management setting, by analysing sustainable urban mobility and cycling promotion in Utrecht, the Netherlands. Theoretical perspective: The study develops a conceptual framework to explain the success of cycling promotion bas
The thesis discusses the abuse of the freedom of establishment of companies in the Internal Market and the change that the Directive of the European Parliament and of the Council (EU) 2019/2121 of 27 November 2019 amending Directive (EU) 2017/1132 as regards cross-border conversions, mergers and divisions [2019] OJ L 321/1 (Mobility Directive) creates to that. The research question of this thesis
In this study, I investigate different ways in which sexuality education can be carried out. The study focuses on different pedagogical approaches towards sexuality education within the Swedish Association for Sexuality Education, RFSU. More specifically, two local branches of RFSU (RFSU Malmö and RFSU Stockholm), with different methods of teaching matters of sexuality, are examined. The study is
