Savanna ecosystems of the Sahel are heavily affected by climate change, leading to drier subtropical regions. These ecosystems play a fundamental role in food security of the region, so that an improved understanding of how these ecosystems are affected by these weather events is thereby critical.

Rare earth elements (lanthanides) are critical materials for many applications, particularly those involved in new energy. Extracting these elements economically from low-concentration sources may be challenging. This study investigates the interaction of Ce and Gd with microalgae that have been triggered to form phosphate-rich granules. Lanthanides usually occur in nature as phosphates, and there

When exposed to high levels of phosphate after experiencing phosphate deficiency, microalgae can synthesize granules rich in intracellular phosphate. The understanding of the mechanism of production and nature of these granules remains incomplete. Here we studied phosphate distribution and chemistry in Chlamydomonas reinhardtii and Desmodesmus armatus using scanning transmission X-ray microscopy (

High-power proton linacs are envisaged as drivers for numerous applications, such as neutron spallation sources for condensed matter study, neutrino factories, muon colliders, hybrid systems for transmutation or energy production, production of rare isotope beams for nuclear physics studies, etc. These linear accelerators are intended to deliver proton beams of up to several MW and tens of MW powe

Scientific breakthroughs in the field of cell and gene therapy lay the groundwork for therapeutic innovation, but their translation and integration into routine care is delayed by systemic inefficiencies and limited cross-sector alignment. The Advanced Therapies model of Lund is a proactive and integrated approach designed to accelerate the development of advanced therapies from discovery to reimb

Stellar clusters are structures of stars that are bound together by their mutual gravitational forces. As a cluster evolves, it will lose stars as a consequence of internal and external effects. The external effect is the most important and affects the cluster via gravitational tidal forces that can strip stars away from the cluster. Stellar clusters are subject to gravitational scattering and tid

Background: Persistent circulating cell-free tumor DNA (ctDNA) detection during neoadjuvant treatment of early-breast cancer (EBC) indicates high-risk disease. Detection of ctDNA post-resection of EBC (molecular residual disease, MRD) indicates occult metastatic disease and impending disease relapse. For ctDNA to be integrated into EBC management, accessible and scalable diagnostic tools are requi

Introduction: Vitamin D deficiency has previously been shown to be associated with cancer-related fatigue. If vitamin D deficiency affects fatigue in frail elderly has not been studied before. The aim of this study was to investigate associations between vitamin D, fatigue, frailty, and sarcopenia in frail elderly with cancer (FEC) and without cancer (FE) in comparison with healthy controls. Metho

The experimental realization of quantum molecular spectroscopy with entangled photons remains challenging owing to the low signal-to-noise ratio resulting from the use of low-flux entangled photons. High-flux entangled photons via intense entangled beams can be used to improve the signal-to-noise ratio, but the presence of unentangled photons contaminates the quantum signal stemming from entangled

Background: Surgical resection of post-chemotherapy residual masses for metastatic seminoma is discussed controversially with regard to oncological and functional outcome. Furthermore, the role of FDG-PET/CT to detect vital seminoma is still unclear. It is the aim of this study is to report the outcomes of patients with pure seminoma who underwent PC-RPLND. Methods: In this retrospective multi-ins

This paper explores regenerative building production as an approach that goes beyond minimising environmental harm to actively generating net-positive socio-ecological impacts. Grounding the discussion in sustainability transitions theory, we highlight how construction significantly contributes to global carbon emissions and waste. Using the phenomena construction methodology, a conceptual framewo

När biometriska metoder används för autentisering är det viktigt både att processen är korrekt, och går snabbt. Givetvis ska en obehörig användare inte kunna passera autentiseringsprocessen, och givetvis är det fördelaktigt om autentiseringen inte tar lång tid. Vid biometrisk fingeravtrycksigenkänning finns flertalet faktorer som försvårar matchningen. Brist på ljus kan göra fingeravtrycksbilden fThis thesis investigated the use of convolutional neural networks (CNNs) for image restoration of fingerprint images, focusing on the reconstruction from raw sensor images to denoised fingerprint images, suitable for matching. Fingerprint images from sensors often introduce noise and artifacts that inhibit the matching process. The goal was to develop a CNN-based approach capable of removing artif

Acoustophoresis enables label-free separation of particles and cells in microfluidic sys- tems, but systematic methods for analysing and comparing separation behaviour re- main limited. In this thesis, a workflow based on the mobility ratio was evaluated as an experimental framework for characterising acoustophoretic separations, using flow cytometry as the analytical tool.

Det svenska socialrättsliga systemet bygger på frivillighet, vilket innebär att socialtjänstens insatser som huvudregel kräver samtycke från både barnet och dess vårdnadshavare. Det kan skapa ett rättsligt mellanläge där barn riskerar att stå utan nödvändigt stöd, när kriterierna för tvångsvård enligt LVU inte är uppfyllda, samtidigt som samtycke till frivilliga insatser saknas. För att åtgärda deThe Swedish social welfare system is based on the principle of voluntariness, meaning that social services interventions generally require the consent of both the child and their guardians. This can create a legal gap where children risk being without necessary support, as the criteria for compulsory care under the Care of Young Persons Act (LVU) are not met, while consent for voluntary interventi
