In this paper, the factors affecting flame extension under curved ceilings are presented. An experimental campaign in reduced scale was carried out in Lund University’s Fire Lab using a propane gas burner and heptane pool fire in different positions and heat release rates within a curved ceiling setup. A flame recognition script was developed to identify the flame length in the videos taken for ea
Since the 1987 UN report “Our Common Future”, aimed at bridging divides among various stakeholders by advocating for “sustainable development”, renewed demands for environmentally adjusted measures have emerged, calling for a future that consolidates socially just, ecologically sound, and economically viable outcomes through sustainable forest management. For Nordic forests, this means policy meas
Energy efficiency is essential for climate change mitigation. Energy management, shaped by both technical artefacts and social constructions, can overcome barriers and achieve greater emission reductions than technology-focused approaches alone. Nine social constructions of energy management emphasize the need for a broader view that includes operations, processes, and knowledge creation and diffu
Tropiskt fiske står i frontlinjen för klimatpåverkan och ökande förluster och skador. Ändå har begränsad uppmärksamhet ägnats åt fisket, särskilt "småskaligt" fiske, vilket spelar en avgörande roll för att upprätthålla försörjning, levnadssätt och välbefinnande. Utan någon konsekvent och ibland omtvistad definition hänvisar förlust och skada till de negativa effekterna av klimatförändringar som inTropical fisheries are at the frontline of climate impacts and rising loss and damage. Yet, limited attention has been paid to fisheries, particularly "small-scale" fisheries, which play a vital role in sustaining livelihoods, ways of life, and well-being. With no consistent and sometimes contested definition, loss and damage refers to the negative impacts of climate change that were not addressed
INTRODUCTION: Tau positron emission tomography (PET) is a reliable neuroimaging technique for assessing regional load of tau pathology in the brain, but its routine clinical use is limited by cost and accessibility barriers. METHODS: We thoroughly investigated the ability of various machine learning models to predict clinically useful tau-PET composites (load and laterality index) from low-cost an
Significance: Optical-quality bioresorbable implants, which gradually dissolve within the body, are gaining increasing interest due to their potential to eliminate the need for revision surgeries. These implants show significant promise in treating deep-seated tumors in high-risk areas, such as the brain, and offer extended capabilities for monitoring interstitial physiological parameters or pharm
This thesis discusses novel results in the area of code-based cryptography, ranging from cryptanalyses on several code-based cryptographic constructions to proposing a code-based authentication scheme based on a novel Syndrome Decoding variant.To address the looming threat of large-scale quantum computers that wouldbreak many widely-used public-key cryptosystems, the National Institute of Stan-dar
The atomic structure of catalytic surfaces and its relation to function is important for the understanding and development of industrial catalysts. However, many surface sensitive methods are limited to low-pressure environments, creating a gap between experimental results and reality, and it is not certain that the findings can be applied to the real system. Surface X-ray diffraction is a method
INTRODUCTION: A recent study on patients with acute lower limb ischemia showed that the proportion of inadequate examination of lower extremity circulation was associated with higher rate of amputation and death. The aim of this systematic review was to explore evidence for how practical competence in performing a peripheral vascular status of the lower limb among medical students and junior docto
Non-typeable Haemophilus influenzae (NTHi) is an emerging respiratory pathogen that causes a significant disease burden worldwide, yet an effective vaccine is still lacking. The focus of this thesis is to elucidate the critical molecular interactions governing NTHi pathogenesis and host immunity. We identified Elongation Factor Tu (EF-Tu) as a surface-exposed protein on NTHi, demonstrating its imm
Tropical forests provide essential ecosystem services, playing a critical role in climate regulation, biodiversity conservation, and regional hydrological cycles while also supporting livelihoods. However, they are increasingly threatened by deforestation and land-use change. Accurate land cover (LC) mapping is vital to monitor these changes, but mapping tropical forests is challenging due to comp
Since the conceptualization of early vascular aging (EVA) in 2008, significant efforts have been made to develop and improve its assessment. Initially lead by the investigation of arterial stiffness through pulse wave velocity (PWV), several additional vascular aging biomarkers have gained prominence in recent years. Despite expanding literature addressing methodological concerns associated with t
