Bakgrund: Aktivitetsbalans är avgörande för individens välbefinnande, särskilt vid kroniska sjukdomstillstånd som multipel skleros (MS). Aktivitetsbalans beskrivs som en relation mellan önskad och faktisk tidsanvändning inom olika aktiviteter. Fatigue är ett vanligt symtom vid MS och innebär en omfattande hjärntrötthet. Fatigue kan påverka aktivitetsbalans och livskvalitet negativt. Syfte: SyftetBackground: Occupational balance is crucial for an individual's well-being, especially in chronic diseases such as multiple sclerosis (MS). Occupational balance is described as a relationship between desired and actual time spent in different activities. Fatigue is a common symptom in MS and involves extensive brain fatigue. Fatigue can negatively affect occupational balance and quality of lif

Då byggbranschen står för en femtedel av den svenska ekonomins totala årliga växthusgasutsläpp, har sektorn en avgörande roll i arbetet mot en hållbar utveckling. Klimatpolitiska mål och styrmedel har tagits fram i syfte att leda branschen mot den hållbara utvecklingen. Lagstadgade klimatdeklarationer och gränsvärden för byggnaders klimatpåverkan är styrmedel för Sveriges färdplan mot uppfyllandetThe construction industry is responsible for approximately 20% of Sweden’s annual greenhouse gas emissions and plays a key role in achieving national climate goals. As building operations become more energy efficient, emissions from the construction phase, particularly from concrete frameworks become increasingly significant. This thesis investigates emission reducing alternatives for a fully pref

”Evighetskemikalierna” PFAS har uppmärksammats mer och mer de senaste åren och behovet för reningstekniker är viktigare är någonsin. Uppgiften är dock utmanande, bland annat på grund av att PFAS är svåra att bryta ner och har spridits över stora områden. Denna studie har undersökt möjligheten att rena PFAS-förorenade områden genom växter, med utgångspunkt i hur väl en växtodling på MSB Revinge utaPFAS (per- and polyfluoroalkyl substances) are a group of synthetically manufactured chemicals contributing to environmental pollution. The largest point source of PFAS in Sweden is the usage of firefighting foam, and at MSB (Swedish Civil Contingencies Agency) Revinge, firefighting foam has frequently been used. Moreover, PFAS is known to accumulate in plants, and a Salix plant cultivation has be

Implantat som bryts ner i kroppen – en lösning för framtidens benbrott Tänk dig att du bryter benet och att skruven som håller det på plats försvinner av sig själv när benet läkt – utan en extra operation. Det kan bli verklighet med nedbrytbara metallimplantat. Vid komplicerade benbrott används ofta metallimplantat för att stabilisera skelettet under läkningen. Dessa tillverkas traditionellt av Biodegradable magnesium alloys are promising candidates for orthopaedic implants due to their mechanical compatibility with bone and their bioresorbable nature. This study investigates the degradation behaviour of Mg-Zn-Zr-Ca alloys with varying zinc concentrations, focusing on how heat treatment and microstructure evolution influence corrosion resistance under physiologically relevant conditions.

Som vi har märkt på grund av de senaste årens höga elpriser är en jämn elproduktion från grön energi väldigt viktig. Solkraft där man lagrar energi i smält salt kan användas för att sprida ut eltillverkningen på alla dygnets timmar. Utvinningen av saltets energi är då högst betydelsefull och denna har undersökts genom effektiva och simpla flödessimuleringar i detta arbete. Dessa flödessimuleringaTo be able to meet the global energy demands, a steady supply of green energy is required, even during sun- or windless hours. Concentrated solar power is a useful alternative, which can produce and store green energy by heating a heat transfer fluid (HTF) and extracting its energy via a heat exchanger. One such category of HTF is molten salts, and to understand and be able to model the behaviour

Ett protein med potential: så kan växternas hemoglobin förändra världen Från blodbrist till vegetarisk kost uppmanas vetenskapen ständigt att hitta lösningar som främjar både hälsa och hållbarhet. En spännande möjlighet finns i phytoglobiner; växternas egna form av hemoglobin. I det här projektet har ett phytoglobin från sockerbeta producerats och optimerats i bakterier, med målet att ta fram ettHemoglobins, part of the globin superfamily, are heme-containing proteins that are involved in numerous biological processes, primarily oxygen transport. In plants, they are known as phytoglobins and serve diverse roles beyond oxygen transportation, with potential applications as artificial blood substitutes, iron supplements, and plant-based meat alternatives.

Plastic has been a revolutionary material in human history. Plastic materials have several desirable properties, such as durability, low production costs, and versatility. This helps explain the increase in their use and production over the past 100 years. Plastics are synthetic polymers, with long repeating chains of monomers; this creates structures that are chemically stable and durable. The ov

Stellar lithium abundances can help answer multiple unanswered questions within modern astrophysics. Lithium is fragile in comparison to other elements found in stellar atmospheres. Consequently, its abundance within the stellar atmosphere is depleted by different processes. Studying these lithium abundances gives insight into the evolution of the stars and the processes within their interiors. Th

The understanding of solid state physics is a significant part of understanding the foundations of modern technology and engineering. Applications of solid state physics are broad; it includes solar panels, laser technology, transistors, light emitting diodes (LEDs), and many more, all of which have been significant technological advancements that have offered people efficient and useful devices a

This study aimed to investigate how institutional staff at special residential youth homes operated by the Swedish National Board of Institutional Care (SiS) experience their authority under coercive legislation. How they perceive their power position regarding the youths, and which ethical dilemmas may arise in their work. The study also explores the experiences regarding the criticism directed a

This thesis explores how welfare crime is discursively constructed as a problem in policy documents from Järfälla, Malmö, and Uppsala, using Carol Bacchi’s What’ s the Problem represented to Be? (WPR) approach. Within a context of turbulence (Ansel et al 2024) the study examines how welfare crime is presented, what remains unproblematized, and the political and discursive effects of these represen

Det är alltmer tydligt att användningen av naturresurser är ohållbar för vår planet. Dagens resursuttag och resursanvändning representerar cirka hälften av växthusgasutsläppen, och 90% av förlusterna av biologiskt mångfald (IRP, 2019) och behöver förändras. Att gå från en linjär ekonomi som bygger på ett ”slit och släng”-mönster, till en cirkulär ekonomi blir allt viktigare. Politiken såväl som näResource extraction and processing contribute to more than 90% of biodiversity loss and water scarcity and about 50% of climate impacts globally. Moving towards a sustainable resource use is fundamental for reducing environmental impact. Resource use is often considered within the framework of the Circular Economy, a concept that has been widely adopted as a key strategy to meet this challenge. In

This thesis explores the right to seek asylum in the European Union (‘EU’) in situations where migration is used as a tool of political pressure - referred to as instrumentalization of migration. The analysis is grounded in Finland, focusing on its Eastern border with Russia where instrumentalized migration has recently occurred - as part of Russia’s broader strategy to destabilize and exert press

Rising logistics costs and inefficiencies caused by Lindab Group’s current internal markup structure have prompted the company to consider a new logistics model. This study examines the feasibility of developing an internal third-party logistics (3PL) provider as a way to improve operations, increase profit and enhance coordination across the group. The research maps current distribution flows, id

The purpose of this study was to investigate whether there is a difference in what individuals consider important when making moral judgments. This was examined through two research questions. The first concerned whether individuals value different underlying factors of morality depending on whether the statement concerns themselves or someone else. The second research question explored whether em

Antibiotika är en av de viktigaste upptäckterna under 1900-talet. Med antibiotika blev det möjligt att bekämpa och förhindra bakteriella infektioner. Ett växande och svårlöst problem är antibiotikaresistans. Detta projekt syftar till att hitta alternativ till klassisk antibiotika. Vi har arbetat med sialinsyra, en kolhydrat som återfinns på cellytan. De flesta bakterier tillverkar inte själva siaThe development and the use of anibiotics since the second half of XX century really affected the approach on treatment and prevention of infectious diseases. Despite a lot of resources and energies has been invested on the research, antibiotics resistance is a growing phenomenon in the last years. Today this problem has become a real public health priority worldwide, not only for the important cl

Today, 55 percent of the world’s population lives in urban areas, a proportion that is expected to increase to 66 percent by 2050. The cities are growing, densifying and expanding. On the dark side of urbanization and rapid growth, the city centres work as dense machineries for businesses, commerce, automobiles and computerization. As a result, significant numbers of urban citizens are experienc

The literature suggests that executives still doubt the real contribution of HR, and one reason for this is that it is difficult to measure the Return on Investment in HR activities. In addition to this, earlier studies on the value creation of IT seems to discount the intangible value creation that IT investments bring to organizations. The purpose of this thesis is to investigate and compare how
