In the pursuit of more sustainable agriculture, weeds play a dual role by threatening crop production and simultaneously contributing to farmland biodiversity. Management actions such as the use of fertilisers (fertilisation) may change weed abundance and community composition with consequences for both weed–crop competition and biodiversity. Alleviating the balance between yield and biodiversity
Transient absorption spectra and kinetics are used for detailed studies of energy transfer dynamics within the B850 ring of the LH2 antenna of the purple bacterium Rb. sphaeroides. The initial exciton relaxation was found to occur within the first 100 fs and no temperature dependence of this process was observed. Trnsient abcorption spectra of the LH2 antenna complex at 6 K revealed a new spectral
Coherent nuclear oscillations in two intact photosynthetic light-harvesting pigments were observed for the first time using the approx. 40-fs tunable pulses from a mode-locked Ti:Sa laser. Furthermore, steady-state optical spectroscopy and theoretical calculations provide evidence that exciton states are present in the pigments. The possible antenna configurations that would give rise to the obser
In 1825, an unnamed Stellenbosch official paused his tax collection duties to pen a poem in the margins of the opgaafrol. His verses capture the frustrations of colonial administration but the records themselves–annual tax censuses spanning 1685 to 1844–offer a far richer window into the Cape Colony’s social and economic history. First established by the Dutch East India Company and later maintain
Background: Although up to 25% of proximal humeral fractures are isolated greater tuberosity fractures (IGTFs), comprehensive epidemiological data are lacking. Objectives: Describe the epidemiology and time trends of IGTF in Malmö, Sweden, 1944–2020. Methods: We identified IGTF in Malmö residents (≥18 years) by reviewing relevant radiology examinations during 17 sample years from 1944 to 2020. Fra
Lignocellulosic materials (e.g., straw and bran) are gaining interest as feedstocks for the manufacture of higher value products, recognizing xylooligosaccharides (XOS) as interesting prebiotic compounds, and putting enzymes converting xylooligosaccharides into focus. In this work, we are investigating a XOS converting enzyme from the probiotic bacterium Levilactobacillus brevis (formerly Lactobac
INTRODUCTION: This study examined trends in socioeconomic inequalities in obesity among Portuguese women and men using data from National Health Surveys (NHSs).METHODS: We analysed weighted data from adults aged 20-64 years from the 1998/1999 (n = 20,581), 2005/2006 (n = 13,088), 2014 (n = 7284), and 2019 (n = 5959) NHSs. Obesity was defined as body mass index (BMI) ≥30 kg/m 2, based on self-repo
En av orsakerna till att näringslivets olika parter har svårt att se sin egen relevans och styrka i det brottsförebyggande arbetet handlar inte bara om den specifika verktygslåda de har till sitt förfogande, utan om det sätt både de och vi har kommit att tänka på och förstå vad som definierar det brottsförebyggande. Med andra ord verkar en huvudorsak till att många företagare uppfattar sig som "pr
The link between the structural organization of the fibrillar components of lung extracellular matrix (ECM), local tissue stiffness and global viscoelastic behaviour is not known. Here we investigated the effect of injurious mechanical ventilation on the local lung tissue stiffness using 4D synchrotron phase-contrast micro-CT, in normal lung and 7 days after intratracheal bleomycin induced lung in
In this doctoral thesis I investigate two key issues at the heart of the ongoing philosophical debate concerning the emotions – their nature and their normativity. I argue against the deeply entrenched view according to which emotions are representational mental states and fitting in virtue of accurately representing their objects. Drawing on recent attitudinal accounts of the emotions, I develop
We know little about the odds of growing old in the later Middle Ages because reconstructions of the longevity and life expectancy of populations require baptismal, marriage, and death registers, which only gradually appear after 1500. The few earlier reconstructions that are available concern males; the female experience of ageing is mostly based on small samples of elite women who lived in the M
Introduction: Person-centred care is being implemented in healthcare to facilitate co-created care and patients' participation in their own care. This is a new practice, also among radiographers. The aim of the study was to explore radiographers' perceptions of the framework of person-centred care and its performance in radiography.Methods: Phenomenography was the study design. Focus group discuss
What makes baby cries, dog barks and piercing screams so disturbing and difficult to ignore? A common explanation is that their salience is enhanced by vocal roughness and unpredictability caused by irregular phonation. A comprehensive investigation in ten perceptual experiments confirmed that human listeners found nonlinear vocal phenomena (NLP: frequency jumps, amplitude modulation, subharmonics
AI-enhanced search applications are evolving rapidly, promising to answer complex queries with simple answers, but this creates new challenges on how users evaluate the information presented to them. This study investigates how four AI-enhanced search applications (ChatGPT, Gemini, Copilot and You.com) respond to questions about erectile dysfunction drugs in Sweden, which risks creating digital gr
BACKGROUND: Accurate risk stratification in older adults presenting to the emergency department (ED) is essential but challenging due to atypical presentations and age-related physiological changes. While vital signs are central to triage, their predictive value for short-term mortality in this population remains unclear. This study aimed to explore the association between initial vital signs and
