Detta examensarbete beskriver processen att utveckla en ny typ av bikupa som syftar till att förbättra tillgängligheten för biodling i urbana områden och förbättra överlevnadsmöjligheterna för bipopulationen. Genom att i större utsträckning efterlikna binas naturliga levnadsvillkor hoppas Allemanskupa minska behovet av skadliga bekämpningsmedel och syror för att hålla bikupan sjukdomsfri. Detta pThis master thesis describes the process of developing a new kind of beehive that aims to improve the accessibility of urban beekeeping and improve the survival chances of the bee population. By emulating bees' natural living conditions to a greater extent, the Allemanskupa hopes to decrease the need of harmful pesticides and acids to keep the beehive disease free. This project is done in col

Ett vanligt problem på cykelvägar är kantsprickor, vilka påverkar trafiksäkerheten och framkomligheten för cyklister negativt och bidrar till ökade underhållskostnader. Cykelvägarna är extra känsliga för den här problematiken då de både är tunnare och smalare än bilvägar. Ett par passager av tunga fordon vid ogynnsamma tidpunkter kan räcka för att cykelvägens kant ska knäckas. Bärförmågan hos åttaA recurrent challenge on cycle paths are edge cracks, which affect the traffic safety and accessibility of cyclists and produce high maintenance costs. Being both structurally thinner and narrower structures than roads, the cycle paths are extra prone to this problem. A few passages of heavy vehicles in unfavourable conditions might be enough to break the edge. The load-bearing capacity of eight m

This interview-based study seeks to gain insight into the varying motivations behind car usage across different societal groups, alongside their attitudes towards travel behavior and transportation options. Its overarching goal is to delve deeper into the factors and constraints that influences individuals’ car use and mode choice. The research methodology involves collecting one-month travel data

Background In this study we examine whether the association between internet use and drinking could be different for different types of internet activities among adolescents. We also adjust for a number of theoretically relevant factors such as peer influence, unstructured activities, impulsivity and parental monitoring. Method The data are drawn from four cross-sectional surveys from the years 20

Economic crimes are – often – abstract crimes. Even for a somewhat well-trained accounting expert, these crimes are ambiguous, hard to detect and difficult to interpret. The abstract character of economic crimes is a problem in need of a solution. The abstractness needs to be reduced in order to make the court case judicially manageable, i.e. possible to work with during the process of trial and l

Dilated cardiomyopathy (DCM) is a leading cause of heart failure and cardiac transplantation. We report a genome-wide association study and multi-trait analysis of DCM (14,256 cases) and three left ventricular traits (36,203 UK Biobank participants). We identified 80 genomic risk loci and prioritized 62 putative effector genes, including several with rare variant DCM associations (MAP3K7, NEDD4L a

Research on early postwar documentation efforts related to the Second World War and the Holocaust conducted by survivors of Nazi persecution has expanded over the past two decades. Yet, research on how knowledge circulatedtween these efforts – especially across various “borders” – is still nascent. This chapter seeks to gain a better understanding of the role of women’s informalworks during the ea

We assessed if fasting plasma insulin levels in pregnant women with obesity are associated with newborns’ abdominal fat deposition (dual-energy X-ray absorptiometry) and with cord blood DNA methylation (450k array) in 232 mother–child pairs from the Treatment of Obese Pregnant women (TOP) study. Fasting maternal insulin at 18-20gw was associated with abdominal/total fat mass ratio in newborns inde

Thirty years on, gender mainstreaming is still a dominant strategy for working with gender equality, even though its effectiveness is debated. This is also the case in Sweden. This study focuses on how organisations in public administration, particularly municipalities and regions, are introduced to and approach gender mainstreaming. It aims to contribute with in-depth knowledge of how organisatio

Micropollutants in wastewater can persist through conventional treatment, threatening ecosystems and human health through toxicity, bioaccumulation, and disruption of biological processes. Limited monitoring, due to cost and methodological challenges, allows these compounds to go undetected, potentially leading to long-term, irreversible impacts. To address this, modern wastewater treatment plants

This study examines the relationship between income-related health inequality (IRHI) and macroeconomic conditions. We complement an income group-based analysis of the impact of macroeconomic conditions on mortality by incorporating an analysis of the concentration index as a comprehensive measure of overall IRHI. Using a recentered influence function regression approach, we estimate the impact of

Background: People with intellectual disabilities experience significant health inequities. Digital interventions for health promotion are rarely designed from their specific needs. This study aimed to uncover core qualities of digital interventions for health promotion by exploring factors influencing health behaviours amongst people with intellectual disabilities. Methods: This study was conduct

The gut microbiota is associated with human health and disease. Here we conducted a genome-wide association study of host genetic factors influencing gut microbiota composition in 12,652 individuals from the Trøndelag Health Study (HUNT), with replication in Nordic cohorts (n = 16,017–21,976). We identified 12 reproducible SNP–species associations across six genomic loci, including known (LCT, ABO

Somatostatin, produced by pancreatic islet δ cells, is a key intra-islet paracrine factor that regulates the secretion of the glucoregulatory hormones insulin and glucagon from β cells and α cells, respectively. Here, we show that glutamate and glucagon released by α cells cooperatively activate neighbouring δ cells through AMPA and glucagon receptors, thereby enabling spatiotemporal feedback cont
