Classical and quantum mechanics describe particle interactions fundamentally differently, yet isolated many-body systems generally thermalise in both descriptions. Recent studies using quantum simulators have observed exceptions to this, where the memory of special initial states is retained through anomalously long-lived revivals. The non-ergodic findings could be explained by Quantum Many-Body S
Introduction: Chagas disease, caused by Trypanosoma cruzi, remains a significant public health challenge, particularly among socioeconomically disadvantaged populations in developing countries. Although two drugs are currently available, their use is associated to severe side effects, and they are only widely accepted as a treatment against the acute phase of the disease. Background: A Waltherione
Head and neck squamous cell carcinoma (HNSCC) is a heterogenous cancer with poor prognosis, especially for patients with advanced or recurrent disease. The complex tumor microenvironment (TME) plays an important role in mediating immune evasion and therapy resistance. To improve preclinical testing, advanced 3D in vitro and ex vivo models such as spheroids, organoids, and tumor slice cultures have
Youth delinquency constitutes a significant social problem, both internationally and nationally. This study explored risk and protective factors that influenced youth involvement in criminal behaviour. The study was based on semi-structured interviews with eight family therapists within social services in Sweden, all of whom had experience with young men involved in youth delinquency. The analysis
Although most homes still appear visually the same as they did a half century ago, their relationship to humans and their surrounding environment has changed significantly in recent years. Conventional residential design is often constrained by rigid layouts, poor adaptability to evolving lifestyles, and insufficient opportunities for individual personalization. As a result, spatial arrangements t
This master’s thesis is a cultural analysis of individuals with Type 1 diabetes, who use Continuous Glucose Monitors (CGM). It focuses on how these devices shape both individual and collective identities within the diabetes community, and beyond. Using a combination of interviews, observations, and a visual ethnographic approach such as participant-designed sketches, this research explores the rol

This thesis critically engages with the concept of forgiveness in the context of reconciliation between Aboriginal and Torres Strait Islander Peoples and non-Indigenous Australians. It examines first the historical development of reconciliation efforts between Indigenous and white Australia and shows a discrepancy between their approaches. Where First Nations Australians emphasise concrete structu
In this thesis, proton-proton collisions at 7 TeV are simulated using PYTHIA. Charm and anticharm quarks are identified as being produced from direct, meaning that the charm and anticharm are pair produced by a hard scattering, or indirect interactions where the charm and anticharm pair is produced from the splitting of a single gluon. This data is used to generate a pT spectrum and correlation fu
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.

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
