Vindkraftverken skjuter i höjden i och med att tekniken blir allt bättre. Detta medan de verk som står ute och snurrar på de allra bästa platserna börjar närma sig slutet på sin livstid. I ljuset av rådande klimatproblem samt samhällets behov av energi kan så kallad repowering, det vill säga uppgradering av anläggningar som producerar förnybar energi vara en möjlighet. Uppgraderingarna görs för atIn the context of the current climate crisis and a growing need for electricity, renewable energy plays an important role. Repowering means upgrading existing renewable energy production with new, more efficient technology to increase production in older sites. Wind-power technology has developed significantly in the last few years and upgrading wind parks in the most suitable locations is relevan

Biofilms in the dairy and food industry, particularly those formed by Bacillus subtilis, present significant contamination and food safety challenges. This thesis investigates the impact of stainless steel surface properties, specifically oxide layer formation and surface roughness of polished coupons, on biofilm development. Bacillus subtilis SA 22 (NCA 72-52; DSM 4181) was cultivated using a CDC

Given the increasing share of renewable energy, particularly solar power, there is a growing attention to resource use and disposal challenges associated with Photovoltaic (PV) modules. PV modules consist of multiple layers of materials like silicon, silver, aluminum, glass, and polymers, which makes them difficult to dismantle and recycle. Many recycling methods involve toxic chemicals and create

We construct the meson-baryon chiral Lagrangian at orders two and three. The Lagrangian is constructed in the three-flavour case and with scalar, pseudoscalar, vector and axial-vector external sources included. We discuss the basic ideas of ChPT and the relations that are used to minimise the chiral Lagrangian. The relations that were used are the Bianchi identity, the Cayley-Hamilton relation, th

This thesis investigates how Armenia’s security dependence on Russia is discursively constructed and maintained through political texts. Analyzing the 1994 and 2020 ceasefire agreements ending the first and second Karabakh war, alongside 18 official statements from the Russian Ministry of Foreign Affairs (2020–2025), the study argues that these texts function not only as records of geopolitical ev

Enligt FN:s miljöprogram står byggsektorn för 37 % av den globala energianvändningen och de processrelaterade koldioxidutsläppen. I Sverige visar den senaste statistiken från Boverket att denna sektor står för 22,1 % av landets totala utsläpp av växthusgaser. Som en del av Sveriges klimatmål har Fossilfritt Sverige satt upp mål att minska utsläppen med 50 % till 2030 och 75 % till 2040, med starktAccording to the UN Environment Programme, the construction sector is responsible for 37% of global energy and process-related CO₂ emissions. In Sweden, the latest data from Boverket – the Swedish National Board of Housing, Building and Planning – indicates that this sector accounts for 22.1% of the country's total greenhouse gas emissions. As part of national climate efforts, Fossilfritt Sver

The aim of this study is to explore social workers' experiences with work-related stress and coping, along with their attitudes towards holistic methods as tools for stress management. Since social workers are at high risk for burnout and work-related stress, it is of interest to explore whether a holistic approach can contribute to increasing sustainability among social workers. Through quali

This paper analysed the returns on delta-neutral straddles around macroeconomic announcements. The results for straddles on all macroeconomic events were negative returns across all weighting methods and across the majority of holding periods. Furthermore, the returns for individual macroeconomic data announcements were negative, except for money supply and employment data which showed inconclusiv

Svanödlor (plesiosaurier) är akvatiska reptiler från mesozoikum, runt 251.9 till 66 miljoner år sedan. Fossil från gruppen har beskrivits globalt sedan tidigt 1800-tal, och inkluderar fynd från marina kretaceiska avlagringar i sydligaste Sverige. Här är det fossila arkivet fragmentariskt, och utgörs huvudsakligen av isolerade tänder och kotkroppar. Endast två fragment från kraniet på en svanödla hPlesiosaurs are aquatic reptiles that roamed the world’s oceans during the Mesozoic, some 251.9 to 66 million years ago. Fossils of this group have been recorded globally since the early 19th century, and include finds in the marine Cretaceous of southernmost Sweden. Here, the record of plesiosaurs is fragmentary (a so called ‘scrap fauna’), and mainly made up of isolated teeth and vertebral centr

This thesis investigates multigenerational living as an architectural response to contemporary social fragmentation and urban isolation, offering an alternative model of dwelling grounded in collective domestic life. Drawing from personal experiences of growing up partly within an extended family, the work is motivated by these factors: intergenerational bonds, the timeless human tendency t

This study aims to explore how it is experienced to be swedish-hungarian in Sweden today. This question is answered by looking at three aspects; double belonging, Hungarian culture and the political situation in Hungary today. The research is based on eight interviews done with people between the ages of 21-26 that either have one or both parents from Hungary or Transylvania, or are themselves bor

The rapid evolution of digital technologies such as Artificial Intelligence (AI) and the Internet of Things (IoT) has fundamentally altered how agreements are formed and executed. Automated contract formations occur when contracts are initiated, negotiated or concluded by software agents or systems with minimal or no human intervention. This presents challenges to traditional legal concepts such a

The paper reviewed a collection of studies from 2015-2025 in Sweden on municipal organizational change, with the aim of discussing challenges and benefits during modern change processes and connecting it to previously existing theories. The results showed that there is some conflict between different governance models (mainly NPM and TBG), that TBG can be implemented differently in different munic
