Vid byggnation av vägar och järnvägar i Sverige idag används nästan uteslutande ändliga resurser som bergkross eller naturgrus som ballastmaterial. Det är av stort intresse att undersöka om till exempel återvunnet material och restprodukter från industrier skulle kunna användas i stället. För detta ändamål byggdes en testväg i november 2024 inne på en avfallsanläggning i Helsingborg. Vägen, som foDuring construction of roads and railways in Sweden today, mainly finite resources such as crushed rock or natural gravel, are being used as ballast material. It is of great interest to investigate whether, for instance, recycled materials and residual products from industries could be used instead. For this purpose, a test road was constructed in November of 2024 in a waste facility in Helsingbor

The purpose of this investigation is to explore and highlight the role of the Third World within a human rights framework during the era of decolonization. More specifically the investigation analyzes in what ways states from the Third World used human rights to argue for the abolishment of colonialism within the context of debates in the 15th session of the UN General Assembly in 1960 and in rela

Den här studien ämnade att undersöka huruvida olika musikgenrer; blues , klassisk musik och rockmusik, samt utan musik (kontrollgrupp), påverkar prestation i matematik. 52 personer deltog i studien och de blev alla tilldelade en av de fyra musikgenrerna genom en mellangruppsdesign. Studien bestod av två test. Första testet var ett standardiserat matematiktest bestående av 12 frågor (refereras till

Naturlig selektion i vilda skalbaggspopulationer Naturlig selektion är en nyckelfaktor för evolutionen. Även om vi vet att mängden variation i egenskaper (fenotyper) ger råmaterial för selektion och om den är genetisk påverkar evolutionens hastighet, har vi fortfarande mycket att lära om hur naturlig selektion påverkar specifika egenskaper över tid. I min examensuppsats undersökte jag hur naturliNatural selection is an important force behind evolution. It is well known that phenotypic variation provides opportunity for evolution, but research into how selection acts on specific traits over time is lacking. In this thesis, I studied how selection acts upon the shape and body size of the beetle Cassida viridis. Across three populations, I measured size (length and area), shape, and lifespan

De svenska riktade ränteavdragsbegränsningsreglerna infördes år 2009 i syfte att förhindra oönskad skatteplanering där den svenska skattebasen urholkas genom ränteupplägg med lån mellan bolag inom samma intressegemenskap. Regelverket återfinns numera i 24 kap. 18–20 §§ IL och begränsar avdragsrät-ten för räntekostnaderna på koncerninterna lån. Regelverket ändrades först år 2013 och sedan igen år 2The Swedish targeted interest deduction rules were introduced in 2009, aim-ing to prevent unwanted tax planning that erodes the Swedish tax base through interest schemes involving loans between intra-group companies. The rules are now located in Chapter 24, Sections 18–20 of the Income Tax Act (ITA) and limit the right to deduct interest costs on intra-group loans. The rules were modified in 2013,

The high-temperature oxidation of stainless-steel parts poses significant problems in power generation, chemical processing, and heat exchanger industries. Stainless steel grades such as austenitic AISI 316L, 310S, and ferritic 430 commonly used in industries undergo carving of oxide scales which diminishes spatial quality, increases corrosion, and reduces thermal conductivity. This thesis focuses

Nya byggnormer – smartare tunnlar? Cut-and-Cover-tunnlar är vanliga vid grund anläggningsnivå i svensk infrastruktur. Dessa betongkonstruktioner utsätts för konstant vattentryck, vilket ställer krav på sprickkontroll. Sprickor uppstår ofta på grund av tvångslaster, exempelvis från temperaturvariationer och krympning, när dessa deformationer hindras av omgivningen. För att begränsa sprickbildning dTunnel structures play an important role in Sweden’s infrastructure. At shallow depths, a common construction method is the so-called “Cut-and-Cover” tunnel, where the tunnel placement is excavated, cast in concrete on-site, and then backfilled. Such tunnels are typically subjected to constant water pressure, which yields high demands on crack control. Cracking in elongated concrete structures oft

Harmful algal blooms pose a threat to public health and the economy, affecting tourism, fisheries, and aquaculture. Complex environmental factors influence their occurrence, but current forecasting models often overlook the role of grazers. Chemical cues released by zooplankton, copepodamides, can trigger the production of toxins in harmful algae. Therefore, their presence in bivalves may enhance

In the pursuit of sustainable chemical production, feedstock diversification is essential. Lignosulfonates, a water-soluble aromatic byproduct of the sulfite pulping process, offer a green alternative for producing value-added compounds such as vanillin via oxidative depolymerization. However, current depolymerization processes are not comparable due to inconsistencies in feedstocks and a lack of

Eye movements originally made during memory formation are often spontaneously reproduced during retrieval, even in the absence of visual input, directing gaze back to the locations where goal-relevant episodic information was previously encountered. This behavior, known as gaze reinstatement, is thought to support the reactivation of episodic content associated with those locations (e.g., Johansso

Background: The multifactorial nature of chronic pain should be reflected in pain assessment. The aim of this observational study comparing samples from three generations assessed at different times was to present differences in pain, stress and mental well-being. Methods: Pain sites, widespread pain, stress (Perceived Stress Scale-4) and mental well-being (30-item General Health Questionnaire) we

Mutations causing Parkinson’s disease (PD) give diverse pathological phenotypes whose cellular correlates remain to be determined. Those with PRKN mutations have significantly earlier selective vulnerability of dopamine neurons, those with SNCA mutations have increased alpha-synuclein deposition, while those with LRRK2 mutations have additional deposition of tau. Yet all three mutation types are i

Purpose: The sugar industry is always pressured to be suitable and enhance its operational effectiveness. Digital Twin (DT) has the potential to transform this industry. However, the lack of industry-specific Key Performance Indicator (KPI) frameworks makes it challenging to implement them. This study provides a hierarchical KPI model for DT adoption in the sugar sector, interconnecting the United

BACKGROUND: Wolff-Parkinson-White (WPW) syndrome is a rare cardiac disorder that predispose to supraventricular arrhythmias. Prognosis is usually benign, yet there is an increased lifetime risk of sudden death. While typically sporadic, familial clustering has been reported. This study aimed to assess the risk of WPW, arrhythmias, and mortality among siblings of individuals with WPW.METHODS: This

BackgroundWorkplace sexual harassment remains a persistent issue in Sweden. Research about organisational antecedents has been criticised for being limited in scope, possibly overlooking contextual factors relevant for the occurrence of sexual harassment. This study examined two factors capturing aspects of organisational climate, perceived relational justice and authoritarian treatment, and their

Background: In the Bagnardi et al. (2001) meta-analysis, it was found that alcohol consumption increases the risk of stomach cancer (OR = 1.32 for heavy drinkers). However, it is unknown if drinking cessation reverses this alcohol-elevated risk. Methods: A systematic literature review was performed to provide the information for a meta-analysis where the dose-risk trend was estimated for years sin

BackgroundAmbulance clinicians increasingly refer patients to self-care, positioning ambulance service within a wider gatekeeping role and necessitating the assessment of whether self-care is a safe option or if further support is needed. Contrary to primary healthcare centre (PHC) referrals, self-care referrals often lack structured follow-ups, with the decision consequences remaining underexplor

Influenza A virus (IAV) is a major respiratory pathogen, causing around 650,000 deaths annually. Asignificant transmission pathway for IAV is via expelled respiratory aerosol. For successfultransmission via the aerosol route, IAV must remain infectious following transport from an infectedhost to a susceptible individual. Many environmental factors may affect IAV infectivity, includingambient relat

Artificial Intelligence is advancing rapidly, raising critical concerns about the integrity of digital content, particularly in sensitive domains such as medical imaging. Recent AI techniques, such as Generative Adversarial Networks (GANs) and diffusion models, can generate highly realistic synthetic medical images, posing risks of misdiagnosis, inappropriate treatment, and other adverse outcomes.

This thesis investigates how the civil war in Syria and flight to Sweden has affected male Syrian refugees’ national identity. I conducted individual interviews with 10 informants, a focus group with 4 informants and participant observation at a café. In this thesis, national identity is defined as a part of an individual’s personal identity and consists of a person’s sense of belonging to a speci
