Freshwater systems are active components of the global carbon cycle and contribute to global CO2 emissions. Freshwater studies in the Arctic are underrepresented, especially regarding lakes and their Dissolved Organic Carbon (DOC) reactivity and composition dynamics. DOC is a main part of DOM (dissolved organic matter), which drives processes central to carbon cycling, influences chemical and biol

Purpose: The thesis aims to address the different roles incumbent firms can take in the emerging plant-based ecosystem and to contribute with new understandings related to these ecosystems. Theoretical framework: The theoretical foundation for the thesis is rooted in theories on systems thinking, ecosystems and with a discussion around the roles that are inherent in ecosystems. This is accompanie

Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. To allow faster acquisition speeds, we explore a deep-learning approach that applies super-resolution and image denoising to fast time-resolved tomograms. The domain translation algorithm

Effectively utilizing Big Data can be a challenge for many companies. Due to its volume, many aspects of the data processing pipeline such as storage, retrieval and usage may quickly become problematic. For example, it could be difficult identifying the relevant metrics when analyzing a service failure. Visualizing and deriving insights from the data could also prove to be quite onerous. Immersive

Numerous African governments are actively implementing diverse strategies to attract increased foreign direct investments (FDI) to bolster their economies. However, there remains an ongoing debate regarding the impact of FDI on economic development, particularly concerning healthcare. Furthermore, there is a notable lack of understanding regarding the influence of Chinese FDI on the African health

Forecasting wind has always been an interesting subject, and as large parts of the world are relying more on wind for power production it is becoming even more important to have reliable forecasts. Probabilistic forecasts, where distributions are predicted in contrast to deterministic forecasts, are impor- tant for informed decision making. We apply two methods based on conformal prediction for pr

Online shopping is gradually becoming a daily behavior in people's lives, and advertising marketing methods based on short videos are also playing an increasingly important role in this trend. Different from pictures and texts, it combines sound and picture, is easy to spread, and contains a lot of information, which conforms to people's habit of using fragmented information. In this case,

This thesis engages with Western European funding for queer movements in Georgia by asking how these donors affect the local movements, transnational politics and the power dynamics in Georgia. It pursues these inquiries by analysing the Western European understanding of queer activism and how donors support queer movements in Georgia; and the Georgian activists perceptions and suggestions for imp

PV system components that are exposed to unmanageable strain can be overheated, which subsequently results in a fire ignition. Common failure factors are poor component quality, mechanical exposure due to natural phenomena and poor craftmanship. The underlying problem is that PV regulations are lacking in quality or are non-existent. The rapid expansion of roof mounted PV system installation on co

This thesis examines the impact of macroeconomic shocks on adolescents health, specifically those aged between 14 and 18 years. Using data from the Youth Risk Behavior Surveillance System (YRBSS) covering U.S. states from 1999 to 2019, this study investigates various health outcomes and behavioural variables among high-school students. A two-way fixed effects model, that accounts for state- and ye

Polisen i Sverige har fått tillsatt målet av regeringen om att ha 26 200 anställda poliser till årsskiftet 2024/2025, tusentals mer än antalet verksamma poliser i dagsläget. Poliser väljer av olika anledningar att sluta i förtid eller säga upp sig, främst på grund av lön och organisationskulturen. Det finns olika teorier om kallelse till yrke och hur uppfattningen framkommit, men ett genomgående t

”Har du gjort gehörsläxan?” är en kvalitativ intervjustudie om lärare och elevers tankar kring gehörslära. I studien har 7 elever och 6 lärare på olika utbildningsformer intervjuats. Studiens forskningsfrågor behandlar ämnen såsom hur gehörsövningar och -strategier kan översättas från lektionssalen till övningsrummet, vilka faktorer som påverkar elevernas möjlighet till enskild övning, samt vilka ‘Have you completed the ear training homework?’ is a qualitative interview study on teachers’ and students’ thoughts about ear training. In the study, 7 students and 6 teachers from different forms and levels of education were interviewed. The research questions of the study address topics such as how ear training exercises and strategies can be translated from the classroom to the practice room,

This study investigates the effects of violating deontic constraints on the Japanese conditional markers to and ba. Via an online survey, native speakers reviewed sentences containing violations of these constraints, evaluating their own ability to understand the sentence and the proficiency of the sentences’ authors. Additionally, they were asked to correct sentences they rated poorly, and determ

I takt med förändringar i klimatet ställs högre krav på hur motståndskraftiga våra städer behöver vara, i en framtid med fler extrema väderhändelser. Vi bor allt tätare och i alltmer komplicerade städer, där flertalet samhällsfunktioner behöver fungera samtidigt. En del i arbetet är att skapa vattenhanteringssystem som klarar av plötsliga stora mängder nederbörd och kan skydda stadens invånare frå

Den ökande globala temperaturen och dess förödande irreversibla effekter på jordens ekosystem är en av mänsklighetens största utmaningar. Den största bidragande faktorn till temperaturökningen är våra ökande utsläpp av växthusgaser, såsom koldioxid, och andra föroreningar. Metrologiska världsorganisationen har estimerat att vi kommer accelerera förbi en temperaturökning på 3 °C år 2100, om vi fortGlobal levels of carbon emissions are constantly rising causing irreversible damages to ecosystems. The heavy transport sector and the industrial sector are responsible for large amounts of the emissions on a yearly basis. Therefore, Power-to-X is presented as an alternative pathway for the production of industry standard chemical, in view of a green transition towards decarbonising emission-heavy

This study examines the beginnings of Hamburg’s institutional transformation from a predominantly Hanseatic-style city to a Northern European financial and economic center. Existing literature has repeatedly pointed out the importance of migrants in the diffusion of economic institutions in the early modern period. In Hamburg’s case, commercially-minded migrants from Western Europe came to Hamburg

This thesis investigated if a human or a robot narrator affected listeners’ comprehension and memory recollection similarly in a narrative story. 103 participants (MeanAge = 35) were recruited to an online experiment to investigate if gestures affected the participants’ narrative comprehension and recollection more than a narrator that did not produce gestures. Participants were presented with the

As a relatively new phenomenon, Artificial Intelligence (AI) has already proven itself to carry the ability to transform modern-day society. With increased AI use becoming more and more prevalent, both its benefits and potential consequences come to light. Companies wishing to reap the benefits AI can offer also need to consider the possible risks associated with its adoption. Many companies decid
