Kraftvärmeverk producerar el, och levererar värme till fjärrvärmenätet. Nätets returflöde till dessa verk har generellt en relativt hög temperatur, och det finns idag verksamheter som använder sig av denna returvärme för att värma upp anläggningar och utrymmen som har värmebehov. Det finns en potential att på liknande sätt utnyttja denna för uppvärmning av växthus, vilket utgör en synergimöjlighetCogeneration plants generate electricity and supply heat to the district heating network. The return flow from the network to these plants generally has a relatively high temperature, and there are currently operations that utilize this return heat to warm facilities and spaces with heating needs. There is potential to similarly use this return heat for greenhouse heating, which presents a synergy

Kvalitetskontrollsmodell för textilåtervinning 2025 infördes en EU-lag som gjorde det obligatoriskt att sortera textilavfall separat. Här presenteras grunden för en modell som relaterar reaktorparametrar till kvalité på återvunnen textilmassa. Textilindustrin omfattade 2024 knappt 2 biljoner USD. Det är en global industri där textilierna ofta designas i USA, produceras i asiatiska länder och slutTextile recycling is highly needed as great amounts of waste are produced every year and most of it is put into landfill or incinerated. This thesis lays the foundations for a quality control system which may be applied for controlling the recycling of cellulosic textiles in an upcoming pilot plant based on ShareTex’s technology. The quality control system was constructed as a mathematical model r

Disparities in health is a common issue in society, with people of different socioeconomic backgrounds having different possibilities in terms of achieving a good level of health. Stress is a common result of this, followed by insomnia and sleep impairment amongst those who are at a socioeconomic disadvantage. In this study, data was collected from multiple Swedish databases to explore whether sle

Tropiska skogar utsätts för mer intensiva och frekventa torkor. Torkor påverkar tillväxt och kollagring i skogen, samt ökar risken för trädödlighet. Det finns flera hypoteser om mekanismerna bakom dödlighet under torka. Två av de vanligaste är något som kallas kolsvält och kavitation. Det är oklart vilken av dessa två mekanismer som inträffar först i tropiska träd under långvarig torka. ExperimentTropical forests experience more intense and frequent droughts. Droughts affect mortality in trees, growth rate and carbon storage in the forest. There are several hypotheses of the mechanisms behind tree mortality during drought. Two of the most common ones are carbon starvation and hydraulic failure. It is unclear which of these mechanisms occur first in tropical trees during long term drought.

Battery energy storage systems (BESS) are becoming increasingly important for storing energy, particularly renewable energy, and stabilizing electricity grids. These systems often use lithium-ion batteries, which are efficient but pose risks during accidents. Rapid implementation of BESS has led to uncertainties in regulations and emergency response protocols. This thesis aims to identify and eval

Radar has come a long way since its invention in the 1930s. It is not only used to detect the distance and angular position of a target but can also measure velocity thanks to the Doppler frequency shift. In more advanced systems, the radar can perform tasks such as imaging and classification of the target. In some cases, full or partial polarimetry is used to gain additional information about the

The growing demand for the recognition of sexual and reproductive rights as a fundamental part of human rights by the approval of policies that make access to them a reality has been classified as one of the factors fueling political polarization, a phenomenon that seems to be transforming global politics, and which was consolidated in the Peruvian context after the 2021 elections. In the middle o

Syftet med denna studie är att skapa en djupare förståelse och klargöra hur generativ AI kan appliceras som ett hjälpmedel för entreprenörer i anbudsprocessen. Offentliga upphandlingar präglas ofta av omfattande informationsmängder, komplexa formella krav och strikta tidsramar. När förfrågningsunderlagen dessutom är bristfälliga eller otydliga blir varje anbud en resurskrävande investering som måsThe purpose of this study is to develop a deeper understanding and clarify how generative AI can be applied as a support tool for contractors in the bidding process. Public procurements are often characterized by extensive amounts of information, complex formal requirements, and strict timeframes. When the tender documents are additionally incomplete or unclear, each bid becomes a resource-intensi

From a market perspective, Japan is interesting for Swedish companies, especially those with sustainable and digital capabilities. However, the Japanese market is complex, with high quality demands and deep relationships, which require foreign companies to understand how their assets transfer locally. This thesis explores how ten Swedish subsidiaries in Japan use sustainability and digitalization

Klimatfrågan är ett ämne som många människor pratar om. De senaste årtiondena har klimatfrågan ökat i samband med ökade utsläpp. Effekterna av utsläppen är tydliga i form av höjda vattennivåer, värmeböljor, extremväder och skyfall för att nämna några. Vad människor gör åt saken beror mycket på hur medvetna människor är om klimatförändringarna. Vissa personer märker inte av klimatförändringarna medClimate change is an important topic for a lot of people and the usage of art to draw attention towards the issue is not a novel idea. Each art piece has had a different approach to, not only increase awareness but to also portray climate change. The expressions vary depending on who made the art piece, the context of its creation and similar parameters. Globally, this has been done since at least

This thesis examines how female-targeting fintech firms can internationalize in ways that genuinely promote financial inclusion for women. Conducted as an exploratory interview study with Female Invest, it builds on the broader observation that gender remains largely absent from fintech’s outlook. The study addresses two key research gaps. First, financial inclusion efforts often overlook how cult

This thesis investigates if graph-based visualisation can be used to enhance usability, user experience, and improve how users find and interact with data in a metadata catalogue. The study took place at E.ON in Malmö where their current catalogue is built using a relational database and where they have wondered if a switch in the backend to a graph-based one would be beneficial. Interviews as wel

Läroplanens öppna och delvis implicita formulering gällande språkhistoria för kursen Svenska 3 på gymnasiet bidrar till ett brett tolkningsutrymme, vilket i praktiken kan leda till betydande variationer för undervisningen. Samtidigt som tolkningsutrymmet möjliggör anpassningar riskerar det även att nedprioritera ämnesområdet till förmån för annat. Studiens syfte är att kartlägga hur svensklärare pThe curriculum’s open and partly implicit formulation regarding language history in the course Swedish 3, contributes to a broad scope for interpretation, which in practice can lead to significant variations in teaching. While this interpretive flexibility allows for adaptation, it also risks deprioritizing the subject area in favor of other content. The aim of the study is to explore how upper se

This qualitative study examines how the divorces of Swedish party leaders Ebba Busch and Jimmie Åkesson are portrayed in Swedish media coverage, with a specific focus on gender-related differences. Using theories of gender, media framing and political mediatization, the study analyzes how media depict the party leaders. Furthermore, it explores how politicians' private and public spheres are p

The accelerating electrification of urban infrastructure and the transport sector is placing in- creasing stress on distribution grid capacity. Distribution system operators (DSOs) are in- creasingly challenged by infrastructure constraints that delay or prevent the connection of new customers. This thesis investigates the use of battery energy storage systems (BESS) as a flexi- ble alternative to

Långsamfilter hjälper till att rena dricksvatten, men när cyanobakterier blommar upp kan de täppa till filtren och störa vattenreningen. Detta projekt ger nya insikter om vad som får cyanobakterierna att blomma i långsamfilter—vi vet nu att de kan växa på socker och att de kanske kan släppa ut fermenteringsämnen. Den vanliga uppfattningen är att cyanobakterier bara bedriver fotosyntes och fixerar Cyanobacteria are involved in nutrient cycling on global, ecosystem, and community scales by producing carbon sources for other organisms. However, recent studies indicate that their role might be more complex. In addition to primary production, many cyanobacteria can also consume carbon sources and secrete fermentation products, thereby impacting interactions with surrounding heterotrophic bacter

På bostadsmarknaden har hyrköp införts som en ny form av boende. Hyrköp går ut på att köparen under en tid hyr bostaden med en option om att köpa loss bostaden vid slutet av optionen. Denna upplåtelseform har hittills varit oreglerad enligt lag, vilket kan skapa osäkerhet. I synnerhet vid hyrköpsavtal med fast egendom där avtal om framtida köp enligt praxis inte är bindande. Inom riksdagen har det
