We report observations of ultrafast carotenoid band shifts correlated with energy transfer dynamics between bacteriochlorophyll (BChl) molecules within the peripheral light-harvesting complex (LH2) from the photosynthetic bacterium Rhodobacter sphaeroides. Direct excitation of the bacteriochlorophyll Q(y) bands yielded distinct changes in the carotenoid S2 absorption from 430 to 530 nm. Transient
Polyoxometalates (POMs) and their instrinsic discrete nature has enabled them to support a wide range of research spanning solution-speciation chemistry, biological/medical assays, catalytic processes and fundamental crystallography. The structure-property relationship of POMs are a consequence of their constiuent metal atoms, which inevitably are formed under specific regimes - for simplicity, ac
Surface water fluctuations and lake storage has been severely impacted by climate change, causing severe flooding and drought events. Hence, monitoring the storage of lakes and reservoirs is of paramount importance to assess freshwater availability, to maintain a balance with the ecosystem and water use. This balance is important for sustainable water management in Sweden, which is reflected in th
Bakgrund: Sepsis är ett livshotande tillstånd som uppstår till följd av ett onormalt systemiskt svar på infektion och kan leda till multipel organsvikt och död om behandling inte påbörjas i tid. Tidig identifiering är avgörande för överlevnad, men symtomen är ofta ospecifika och svåra att tolka. Inom akutsjukvård har sjuksköterskan en central roll i att upptäcka tidiga tecken, initiera åtgärder oc
Personer som självskadar har historiskt sett inte haft så mycket att säga till om i sina egna vårdprocesser. När de har sökt psykiatrisk vård akut, ofta för att de upplevt akut svåra tankar och impulser att skada sig själva och kanske har planerat göra suicidförsök, har personer som självskadar ofta blivit hemskickade utan hjälp, eller så har de blivit inlagda för långvarig psykiatrisk vård som faPeople who self-harm have historically not had much say in their healthcare processes. When seeking psychiatric emergency care, people who self-harm have frequently been turned away, or admitted for lengthy hospitalisations that may aggravate self-harm. The attitudes of psychiatric clinicians toward people who self-harm are important to healthcare users’ experience of care, affecting quality and a
I denna studie undersöks en vanlig fråga i utvecklingsländer - att informella arbetsrelationer kvarstår när den småskaliga gruvsektorn (ASM) ställs under statlig kontroll. Detta undersöks genom en studie av formaliseringsreformer i Rwandas 3Ts-sektor (tenn, tantal, volfram) för småskalig gruvdrift, som intensifierades från 2010. Forskningen syftar till att förklara den roll som arbetskraft, som båThis study explores a common issue in developing countries – the persistence of informal labour relations when the artisanal and small-scale mining (ASM) sector is brought under state control. It investigates this through a study of formalisation reforms in Rwanda’s 3Ts (tin, tantalum, tungsten) small-scale mining sector, which intensified from 2010. The research aims to explain the role that labo
Socialdemokraternas affärskomplex är enormt. Ingen annan liberal demokrati uppvisar lika täta och långvariga kopplingar mellan den offentliga sektorn och företag med starka band till det statsbärande partiet. Dessa nära förbindelser öppnar för korruption och bör omedelbart granskas av OECD, skriver Lars Jonung i en krönika.
Bacterial pathogens deploy diverse virulence factors to subvert host immunity, yet the molecular details of these interactions often remain unresolved. Here, we investigate the structure and host interactome of the Streptococcus pyogenes nuclease A (SpnA). We characterized the structure and dynamics of SpnA using hydrogen-deuterium exchange mass spectrometry and single-particle electron cryo micro
We study how entanglement in photoionization is transferred from an electron-ion pair to an electron-photon pair by fluorescence. Time-resolved von Neumann entropies are used to establish how information is shared between the particles. Multipartite entanglement, between electron, ion and photon, is found on intermediate timescales. Finally, it is shown how a phase-locked two-pulse sequence allows
This thesis examines users’ responses to immersive art installations and the curatorial challenges of exhibiting such hybrid, “phygital” forms. It asks: How do the virtual worlds created by Danish artist Jakob Kudsk Steensen evoke emotional responses and empathy, shaping users’ understanding of the world? How do exhibition design and curatorial aesthetics influence users’ embodied encounters wit
Field relationships and petrology of a mid Proterozoic (1624 ±6 Ma) hornblendite from southwestern Sweden demonstrate that it originated as a mafic-ultramafic hydrous melt. Lobes and veins of hornblendite penetrate the surrounding gneiss and small gneiss xenoliths lie in the main body of the hornblendite, evidence that it intruded with relatively low viscosity. The hornblendite has a composition c
Vi människor lever genom berättelser, men det är dramat som ställer livet och levandet på sin spets, som får oss att lyssna mer uppmärksamt, minnas viktiga erfarenheter bättre, känna starkare och tänka klarare. Därför dramatiseras nyheter och därför konsumerar vi drama från morgon till kväll på tv, mobil och padda. De flesta av oss har därför rika och varierade erfarenheter av drama och vi har nog
Despite substantial contextual differences between the West and China, systems approaches have been recognized as essential for addressing complex and dynamic management challenges, particularly within the field of innovation. However, most previous studies are rooted in traditional cybernetics within the framework of first-order science, which is characterized by linear processes and stable eleme
A single zircon grain dated by ion probe with a minimum age of 3432±30 Ma was found in a microgranite dyke, which cuts norite of 916±11 Ma Hakefjorden Complex at Älgön on the Swedish west coast north of Gothenburg. Zircons are a rare accessory mineral in this dyke. They could be classified by morphology as orthocrysts and xenocrysts. Data from four orthocrysts show that the dyke originated between
