Let $G$ be a Lie group equipped with a left-invariant Riemannian metric. Let $K$ be a semisimple and normal subgroup of $G$ generating a left-invariant conformal foliation $\F$ on $G$. We then show that the foliation $\F$ is Riemannian and minimal. This means that locally the leaves of $\F$ are fibres of a harmonic morphism. We also prove that if the metric restricted to $K$ is biinvariant then $\
BACKGROUND: Long COVID and cardiovascular autonomic dysfunction, including postural orthostatic tachycardia syndrome (POTS), present significant healthcare challenges. Long-term monitoring is challenging due to the evolving nature of symptoms and the limited availability of objective diagnostic tools. With over 200 million electrocardiogram (ECG)-enabled smartwatches sold worldwide, these devices
This paper provides a comprehensive overview of quantile-parameterized distributions (QPDs) as a tool for capturing expert predictions and parametric judgments. We survey a range of methods for constructing distributions that are parameterized by a set of quantile-probability pairs and describe an approach to generalizing them to enhance their tail flexibility. Furthermore, we explore the extensio
ODIN (Optical and Diffraction Imaging with Neutrons) is a general purpose imaging in- strument under construction at the European Spallation Source (ESS). The instrument will provide the scientific community with a wide array of neutron imaging techniques, including neutron tomography. Coupled with an integrated X-ray source, the instrument will feature multi-modal capabilities. The complementary
The purpose of this research was to explore the relationship between war and media in the context of the Israel-Hamas war, which broke out after Hamas attacked Israel on October 7th, 2023. The textual news content of two sources were selected for analysis, CNN, in the first three months of conflict, and IRNA, in the first week of conflict. An exploratory mixed methods research was devised for unde
Plattrambroar är den vanligaste brotypen i Sverige. Dessa konstruktioner är robusta och motståndskraftiga, med förmåga att ta upp betydande laster och motstå deformationer. På grund av strukturens utformning genereras stora tvångskrafter vid infästningen mellan farbana och ramben vid temperaturlaster såsom temperaturskillnad mellan konstruktionsdelar och temperaturgradienter i broplattan. Dessa tv
This thesis explores BDSM as a socially embedded, ethically complex, and transformative practice situated at the intersection of intimacy, power, and identity. Drawing on qualitative data from an anonymous online survey of thirty-eight BDSM practitioners, the study analyzes how power, consent, performance, and rituals function both as personal expressions and as practices shaped by broader social
This study investigates the impacts of rural tourism on the livelihoods of communities in the Sigiriya region of Sri Lanka, a UNESCO World Heritage site celebrated for its cultural and natural heritage. Adopting a qualitative case study approach, it integrates the Sustainable Livelihoods Framework (SLF) and Dependency Theory to examine both the developmental opportunities and structural constraint
Obstetric violence, also known as mistreatment or abuse during childbirth, is gaining recognition in the reproductive justice and global health arenas. Research to date has underscored its global prevalence, long-lasting impacts on individuals, and contributing forms of structural and gendered violence. However, attention is lacking on how discourses about obstetric violence are constructed and di
Vatten är en livsviktig men samtidigt alltmer omstridd resurs, särskilt i områden där ekologisk sårbarhet möter konkurrerande socioekonomiska behov. Denna avhandling analyserar styrningsdynamiken inom Machángara Watershed Conservation Committee i Cuenca, Ecuador – en flerpartsplattform där offentliga institutioner, lokala myndigheter, akademin och sektoriella aktörer samverkar för att skydda ett kWater is an essential yet increasingly contested resource, particularly in regions where ecological vulnerability intersects with competing socio-economic demands. This thesis examines the governance dynamics of the Machángara Watershed Conservation Committee in Cuenca, Ecuador — a multi-stakeholder platform bringing together public institutions, local governments, academia, and sectoral actors to
Since the country’s graduation from the United Nations Least Developed Countries (UNLDC) list in 2015, there has been a sharp drop in foreign aid inflows in Bangladesh, whichforced many NGOs to reconsider their business models in managing organizational operatingfinances. This study identifies that development-NGOs are confronted with multiple internaland external challenges like decreased commitm
This study examines determinants of child marriage among women in Zimbabwe using data from the 2015 Demographic and Health Survey and the 7th wave of the World Values Survey. The purpose is to assess the effect that individual-level empowerment, and community-level social norms have on child marriages in Zimbabwe, testing if: H1 Higher levels of empowerment on an individual level is associated wit
Background.In some regions, including the Baltic Sea, fatty fish such as salmon and herring contain high levels of polychlorinated dibenzodioxins and dibenzofurans. We investigated human exposure to these potentially toxic substances in relation to the consumption of fish from the Baltic Sea.Methods.Plasma levels of 10 different dibenzofurans and 7 dioxins were analyzed in three groups of Swedish
We study transportation networks controlled by dynamical feedback tolls. We consider a multiscale transportation network model whereby the dynamics of the traffic flows are intertwined with those of the drivers' route choices. The latter are influenced by the congestion status on the whole network as well as dynamic tolls set by the system operator. Our main result shows that a broad class of dece
The spread of new beliefs, behaviors, conventions, norms, and technologies in social and economic networks are often driven by cascading mechanisms, and so are contagion dynamics in financial networks. Global behaviors generally emerge from the interplay between the structure of the interconnection topology and the local agents' interactions. We focus on the Threshold Model (TM) of cascades first
Background: Since its discovery in 2007, the importance of the human gut bacterium Prevotella copri (P. copri) has been widely recognized with its links to diet and health status and potential as next generation probiotic. Therefore, precise, convenient and cost-effective diagnostic tools for the detection and quantification of P. copri from clinical and environmental samples are needed. Results:
Implementing anammox based processes in the mainstream at municipal wastewater treatment plants is challenging and requires carefully constructed control strategies in order to be successful. A method to measure the specific anammox activity was further developed and implemented in the mainstream anammox pilot plant at Sjölunda Wastewater Treatment Plant. The method was found to be reliable and re
In this paper, we approach the two weighted boundedness of commutators via matrix weights. This approach provides both a sufficient and a necessary condition for the two weighted boundedness of commutators with an arbitrary linear operator in terms of one matrix weighted norm inequalities for this operator. Furthermore, using this approach, we surprisingly provide conditions that almost characteri
Experimental Modal Analysis (EMA) plays a crucial role in understanding the dynamic responses of structures to vibration by extracting their modal parameters such as natural frequencies and modal damping and vibration modes. These parameters are essential for assessing structural performance and identifying potential vulnerabilities. As the construction industry embraces sustainable materials, Cro
Extensive studies have shown that humans process faces holistically, considering not only individual features but also the relationships among them. Knowing where humans and dogs fixate first and the longest when they view faces is highly informative, because the locations can be used to evaluate whether they use a holistic face processing strategy or not. However, the conclusions reported by prev
