BACKGROUND: Falls are common among older persons and can have a major impact on their lives. Wearable sensors used in free-living conditions (moving naturally in one's daily living environment) can be used to predict falls and fall risks. To understand if using the wearable sensors is an acceptable way for older persons to be screened for fall risks, it is important to have knowledge of older pers

This master thesis investigates the synthesis, structural characterization and electrochemical performance of copper(II) oxide (CuO) and cobalt-doped CuO nanofibers as electrocatalysts for the electrochemical nitrate reduction reaction (NO3-RR). The overarching aim is to assess their potential for sustainable ammonia production under ambient conditions. A series of exploratory synthesis trials rev

Entanglement in quantum mechanics manifests in two distinct forms, either between many qubit systems or two high-dimensional quantum systems with entangled degrees of freedom. These two classifications are well established. However, recent strides have been made to unify these two conditions as quantum technologies evolve further. The GME-dimension quantifies the entangled degrees of freedom in a

The Light Dark Matter eXperiment (LDMX) is a planned missing momentum and energy experiment at SLAC, the purpose of which is to produce dark matter through production at an accelerator. A key theoretical process making this possible is called "dark bremsstrahlung," where an electron scattering off a nucleus produces a dark photon instead of a Standard Model photon. LDMX aims to detect da

Detta arbete är en explorativ studie om svenska fysiklärare på gymnasiet och hur de ser på språkets roll inom fysikämnet samt hur de ställer sig som lärare i rollen att behöva vara en lärare som undervisar språkliga element. Studien genomfördes med hjälp av kvalitativa intervjuer där totalt fyra lärare med varierande erfarenhet som fysiklärare intervjuades. Resultaten analyserades med hjälp av ett

This thesis presents a simulation-driven methodology for evaluating float design in aseptic filling machines, with the objective of reducing surface instabilities and air entrainment that contribute to splashing during the filling of viscous food products. The study was conducted in collaboration with Tetra Pak and focuses on understanding how float geometry, particularly mass and radius, affects

Non-native plants are a growing problem in Antarctica. By encroaching on native plants’ habitats, they risk leaving the last frontier of authentic wilderness irreversibly altered. As the climate continues to change and more people visit Antarctica, non-native plants’ spread and impacts are expected to become more severe. The Protocol on Environmental Protection to the Antarctic Treaty prohibits in

Sociological approaches to culture are divided into interpretive, representational, and embodied perspectives, each grounded in distinct ontologies and causal logics derived from realism and interpretivism. This article aims to bridge embodied and representational approaches and their concomitant philosophies of science. It proposes a concept of meaning-making that unifies representational approacSociological approaches to culture are divided into interpretive, representational, and embodied perspectives, each grounded in distinct ontologies and causal logics derived from realism and interpretivism.

BACKGROUND: Existing conceptions of teaching quality assume that classroom interactions serve as the foundation for effective teaching. The resulting data necessitates analytical approaches capable of extracting the semantics of these interactions.AIM: This study investigates whether and to what extent lesson semantics provide insights into teaching quality (i.e., cognitive engagement, encourageme

Amyloid-β (Aβ) positron emission tomography (PET) imaging and cerebrospinal fluid (CSF) biomarkers are now established tools in the diagnostic workup of patients with Alzheimer's disease (AD), and their use is anticipated to increase with the introduction of new disease-modifying therapies. Although these biomarkers are comparable alternatives in research settings to determine Aβ status, biomarker

In clinical trials, surrogate endpoints, that are more cost-effective, occur earlier, or are more frequently measured, are sometimes used to replace costly, late, or rare true endpoints. Regulatory authorities typically require thorough evaluation and validation to accept these surrogate endpoints as reliable substitutes. To this end, the meta-analytic framework is considered a very viable approac

Objectives: Staphylococcus saprophyticus (S. saprophyticus) is the second most common bacteria causing uncomplicated urinary tract infections (UTIs). It is considered non-susceptible to mecillinam, with no defined breakpoint and only few available minimal inhibitory concentration (MIC) observations. However, this consideration does not correlate with clinical outcome. With this study, we aimed to

Head-mounted mixed reality devices are making their way into airline pilot training. Devices that use passthrough video hold much promise but come with caveats. Because current generation passthrough video devices occlude natural light, users rely entirely on a digital video feed that lacks the visual fidelity and field of view of the unaided human eye. The application of head-mounted extended rea

The exponential growth of Big Data, the Internet of Things (IoT), and Large Language Models (LLMs) has significantly increased the computational and energy demands of modern computing systems. In response, research has increasingly focused on alternative machine learning paradigms and hardware architectures that reduce model complexity and computational load. One such paradigm is the Kolmogorov-Ar

Public organisations need legitimacy to operate and there are many ways for them to gain, maintain and repair it. Without legitimacy, public organisations can face challenges such as legitimacy gaps or crises, which can have lasting effects on their function and authority. This thesis aims to shed light on how public organisations in Iceland communicate when their legitimacy is questioned and wha

Entrepreneurial decision-making is a complex and dynamic process influenced by the challenges, uncertainty, and environmental situations inherent to the entrepreneurial journey. This study investigates how entrepreneurs with relevant professional backgrounds navigate the shift between analytical, structured and intuitive, experience-driven decision-making approaches over time. The methods involved

This thesis explores how sustainable entrepreneurs adapt their motivation and identity amid the emotional, moral, and strategic tensions of building purpose driven ventures. While previous research has examined motivation and identity separately, little attention has been paid to their interdependence, particularly in high uncertainty environments where values and viability collide. Integrating Se

bstract The real estate sector in Sweden has long been characterized by high entry barriers, strict regulations, and a high demand for large initial capital. These factors make it challenging for new ventures to succeed in the market. With this background, it seems relevant to understand which driving factors can be related to entrepreneurial success. This study researches how specific characteris

This thesis explores how sustainability-oriented venture capital firms (sVCs) evaluate sustainability-oriented early-stage startups. While sustainability has gained prominence in financial discourse, its role in early-stage venture evaluation remains diffuse. Startups with strong sustainability missions often face investor hesitation; not due to lack of relevance, but due to limited standardizatio
