During migration birds are exposed to several challenges, one of these are the potential threat of getting oxidative stressed. Oxidative stress can be defined as when free radicals are produced in a vastly amount so antioxidants cannot detoxify them. This is the case at higher metabolic rate such as migratory flight, and probably during hyperphagia at stop-over. The aim of this paper was to invest

Minskade koldioxidutsläpp från energisektorn är nödvändigt om Sverige ska kunna nå klimatmålet inga net- toutsläpp av växthusgaser senast 2045. Biobaserad kraftvärme som drivs på restprodukter från skogsindustrin har möjligheten att bidra till minskade utsläpp men bränslena måste vara miljömässigt hållbara. Detta arbete undersöker potentialen för ett ökat uttag av grot, grenar och toppar, från sveReducing carbon dioxide emissions from the energy sector is essential if Sweden is to achieve its climate target of net-zero greenhouse gas emissions by 2045. Bio-based combined heat and power (CHP), fueled by residual products from the forest industry, has the potential to contribute to reduced emissions but only with enough fuel that’s environmentally sustainable. This study investigates the pot

More than half of the world's population today lives in urban areas, and the relationship between the city and the sea has always played a central role. Studies show that access to waterfront environments in port cities historically been limited, but as urban development progresses, the coastline is gaining increasing significance in the urban context. This presents both opportunities and chal

The Thesis examines how political news satire functions within Armenia's hybrid political regime by analysing ArmComedy, a well-known satirical show. Current scholarship on political satire mostly focuses on Western, developed democracies and examines effect-based questions of knowledge, mobilisation, engagement, and participation, leaving a gap in understanding how political satire functions

Material traceability is an important part of industrial manufacturing, especially in systems where quality, reliability, and documentation requirements are high. In many companies, traceability is often assumed to already exist because there are certificates, ERP systems, production documents, and established routines. However, during this study, it became clear that having information available

This thesis investigates how existing urban environments can be adapted to strengthen climate resilience and improve everyday access to urban rest within dense cities. Urban rest is understood as restorative conditions within the everyday urban environment, where opportunities for pause, recovery, and social interaction can occur across both public and semi-private spaces. The thesis identifies an

Amelogenin self-assembly is a critical step in enamel matrix organization, supporting the spatial confinement of transient ACP and orchestrating hydroxyapatite nucleation and ordered growth. Studies have demonstrated that amelogenin self-assembles into nanoribbons by forming an amyloid-like structure that matches the cross-β pattern observed in the developing enamel matrix. However, molecular dete

Wind energy is an important form of clean energy, and its rational utilization represents a crucial solution for mitigating the energy crisis and global warming. In this study, wind energy potential and its long-term changes in the South China Sea (SCS) are evaluated using ERA5 100 m wind data from 1944 to 2023, validated against ASCAT observations. High wind speeds and high wind power density (WP

Spatial compositional data with exact zeros arise in many applicationsbut remain challenging for models that often assume strictly positivecomponents. We develop a Bayesian spatial model that combines theDirichlet Composition Distribution, which accommodates exact zeros throughcomponent-specific zero probabilities, with a Gaussian Markov random field representationof the latent compositional field

Great Snipes Gallinago media spend about eight months per year in sub-Saharan Africa, but most aspects of their non-breeding ecology are poorly known. We analysed the seasonal pattern of appearance, flight feather moult (primaries and secondaries), and body mass in relation to age and sex, based on 3,247 birds collected by hunters in 1990–2000 in Benin, Gabon, Cameroon and the Democratic Republic

BACKGROUND: Fibroblast growth factor 23 (FGF23), a bone-derived hormone that regulates phosphorus and vitamin D metabolism, contributes to the pathogenesis of mineral and bone disorders in CKD and is an emerging cardiovascular risk factor. Central elements of FGF23 regulation remain incompletely understood; genetic variation may help explain interindividual differences.METHODS: We performed a meta

Media Experiences travels across people and popular culture, exploring the pathways to engagement and the various ways in which we shape and are shaped by the media landscapes in which we move. This exploration includes the voices and bodies, sights and sounds of audiences as they experience entertainment through television drama, reality TV, at live events, and within digital television itself, a

Background: With improving survival in ovarian cancer, second primary cancers (SPCs) and their etiological foundations are becoming an issue. The ways in which family history may influence the occurrence of SPCs and the related mortality are not well known. Methods: Based on the Swedish Family-Cancer Database, we identified 11,300 ovarian cancer patients and followed them for diagnoses of SPCs unt

With timely allocated movement phases, mobile organisms can match their space-use with the seasonality of the environment and thereby optimise their resource utilisation over time. Long-distance avian migrants are known to move with the seasonal dynamics on an annual basis, but how individuals respond to seasonality within their tropical non-breeding range has been less studied. Here we analyse th

The risk among asphalt workers of developing adverse health effects may increase due to their occupational exposure. One area of special concern arises when rubber granules are mixed into bitumen to enhance asphalt properties. This research characterizes and compares bitumen and rubber bitumen regarding the emissions of and workers' exposure to particulates, polycyclic aromatic hydrocarbons (PAHs)

Historical wage studies have never been able to truly or accurately address the changes in the working year. Real wages have almost always been based on the wages of unskilled and casual laborers, typically paid by the day. Their annual incomes are not clear or obvious – the income is directly dependent on how many days they work. Implicitly the literature has assumed that the number of days work

BACKGROUND: Population-based data on subsequent neoplasms after women are diagnosed with endometrial and ovarian carcinomas are limited, particularly regarding specific histologic tumor types.METHODS: The nationwide Swedish Family-Cancer Database of 10.2 million individuals, which includes 19,128 invasive endometrial carcinomas and 19,440 ovarian carcinomas, was used to calculate standardized inci
