Omvandling av energi har spelat en stor roll i samhällets utveckling: från eldens upptäckt via vatten- och väderkvarnar till kol och olja under industriella revolutionen. Gemensamt för alla dessa energiformer är att de antingen går att lagra, som i bränslenas fall, eller att variationer i vatten- eller väderförhållanden inte har någon stor påverkan på resultatet. I elnätet, däremot, måste det rådaThe subject of energy storage is of increasingly more research interest with a larger share of unpredictable and cheap renewable energy entering the grid. Behind only batteries and pumped hydro in technological maturity, compressed air energy storage stands as a possibility in balancing the grid of the future, with its main benefits being highly efficient utilisation of fuel energy and high flexib

What makes a beetle attractive? My project looks at how green tortoise beetles (Cassida viridis) choose partners, and which physical traits have a higher success in obtaining a mate. I did this by tracking individuals in three wild populations of Skåne, Sweden, and taking photographs of mating beetles. To document differences between the sexes and populations, see how many partners a beetle has,

Det finns få behandlingar som leder till betydande symptomlindring för patienter som lider av Somatic Symptom Disorder (SSD), men den internetbaserade psykodynamiska terapiformen Emotional Awareness and Expression Therapy (I-EAET), har visat lovande resultat. Dock finns det inte mycket kunskap om patienters erfarenheter av internetbaserade behandlingar på lång sikt. I denna studie intervjuades tolFew treatments lead to significant symptom reduction for patients diagnosed with Somatic Symptom Disorder (SSD), but the internet-based psychodynamic Emotional Awareness and Expression Therapy (I-EAET) has shown promising results. However, little is known about the patients’ long-term experiences of internet-based treatments. In this study, twelve participants who had undergone I-EAET were intervi

The thesis investigates how a brownfield development, a harbour, can be developed, how urban agriculture, both commercial food production and recreational cultivation, can be integrated into the design and how it should be designed to be both effective and enjoyable and inviting for visitors. A design proposal has been produced that shows such a development. The design proposal is supplemented wit

During installation of firmware updates over the air, servers will usually collect data with statuscodes and information about the installation and update process. Given a large dataset with multiple installation steps, errors might occur occasionally dependant on outside factors such as internet connection, limited storage space or other issues that are not directly related to the stability of th

Vad kostar det om ett exploateringsprojekt stöter på oförutsedda problem kopplade till naturvärden som man måste ta hänsyn till vid en markexploatering? Hur kan naturvärden egentligen påverka den ekonomiska kalkylen i ett projekt om de dyker upp som en överraskning under projektutvecklingen? Intressant är även att undersöka om det med träffsäkerhet går att identifiera, men också att prissätta och What is the cost if a development project encounters unforeseen difficulties related to values in nature that must be considered during a land development? How can natural values affect the balance sheet of a project if they appear as a surprise during project development? It is also interesting to investigate whether it is possible or not to identify and price risks related to nature in the proje

Svenska kommuner befinner sig just nu i en ansträngd ekonomisk situation med både brist på ekonomiska resurser och personal. Samtidigt råder det en efterfrågan på bostäder och i 180 av 290 svenska kommuner råder det ett underskott på bostadsmarknaden. Till följd av den begränsade resurstillgången måste kommunerna därmed prioritera vilket innebär att de måste fördela sina resurser till det som anseSwedish municipalities are currently in a constrained economic situation with a shortage of both financial resources and personnel. The municipalities hold a zoning monopoly, and due to the limited financial resources they have to prioritize within their physical planning to ensure they allocate their resources on what is most important.

In 2015 Sweden received a substantial amount of refugees from the Middle East compared to other European countries, which caused debate concerning Sweden's refugee politics. Some political parties wanted to focus on helping in the nearby area instead of the refugees coming to Sweden. When Russia invaded Ukraine in 2022 refugees fled to Sweden again. The discussions throughout the society at th

The main drivers of the alarming biodiversity decline are land use and land use change, primarily due to agriculture. It is therefore important to assess the impact on biodiversity caused by production of food and to do so, life cycle assessment (LCA) is a method widely used. Since the UNEP-SETAC provisionally recommended the method by Chaudhary et al. (2015, updated 2018) for impact assessments o
