Microplastics are becoming an increasingly bigger problem, and there are currently around 150 million tons of plastic in the ocean. Most plastic in the ocean was released on land and then transported to the ocean. There are, however, microplastics released directly into the ocean, for example from boat paint. This study will investigate paint microplastic released from the storage area in a Swedis
This study examines whether gold and Bitcoin improve mean-variance portfolio performance relative to a traditional stock-bond benchmark, and whether their contributions differ across negative and positive stock-bond correlation regimes. Using monthly U.S. data from December 2014 to December 2025, the analysis applied a rolling estimation framework, mean-variance optimization, Sharpe ratio tests, a
Background: Blood cultures (BCs) are key diagnostic elements for sepsis patients. Accurate preanalytical procedures are substantial, and results should be available as soon as possible to guide adequate antimicrobial treatment. This study aimed to evaluate BC collection practices and diagnostic capacity across European hospitals. Methods: This cross-sectional survey investigated BC diagnostics in
Randomized controlled trials (RCTs) of fecal microbiota transplantation (FMT) in patients with irritable bowel syndrome (IBS) have produced outcomes varying from no effect at all to high efficacy and durable effects over time. This review analyzed differences in the protocols used in FMT RCTs for IBS in the recently published literature with the aim of identifying the factors responsible for the s
This chapter looks in detail at the role of young female entrepreneurs in the handicraft industry, and examines why young women choose to enter the sector and the capitals on which they draw in operating their enterprises. Handicraft production by young women in western Uganda is typically based on both informally and formally learned skills and makes use of locally available and/or purchased raw
Current strategies to reduce the climate impact of production and consumption are insufficient to meet the pressing targets of the Paris Agreement. To expand visions of the possible ‘solution space’ in climate transitions, we explore a framework based on two dichotomies centred around the role of labour and the composition of economic output. From these dichotomies we sketch out four pathways for
Animals have evolved multiple sensory systems that can acquire environmental information guiding their behaviour, allowing them to adapt physiological parameters to current conditions. However, over the past century, anthropogenic changes have increasingly made information on environmental conditions less reliable, by introducing novel elements (such as synthetic chemicals or artificial light), by
Background and ObjectivesThe number of older adults living alone is increasing globally, often with varied risks and resilience capacities. Digital technologies may help mitigate these risks, but their potential remains poorly understood. This review maps evidence on digital technologies in social and health care interventions for older adults living alone, focusing on technology types, functions,
This article studies local enactments of “smart” in and through visions of six smart district development projects. We show that smart cities’ framings of the future are inevitably diverse, emerging from local assemblages consisting of a wide array of heterogeneous elements that translate global imaginaries of the smart city to meet local specificities, needs and agendas. We demonstrate that visio
Polar growth and cell shape determination in mycelium-forming Streptomyces bacteria depends on the function of a polarly localised multiprotein complex that directs cell wall synthesis – the polarisome. This complex assembles around the essential cell polarity determinant DivIVA, alongside other largely unknown components. We report here the discovery of a conserved hybrid histidine kinase-like pr
BackgroundColorectal cancer with overgrowth into urinary organs requires en-bloc resection of involved organs to achieve negative resection margins (R0). This study investigates survival and oncological outcomes after colorectal cancer surgery with resections of urinary organs.MethodPatients undergoing colorectal cancer surgery with urological resection in Sweden 2007–2018 were identified via the
Ammonia/diesel dual-fuel compression-ignition engines are a promising solution for reducing carbon emissions in marine applications, yet their combustion efficiency and nitrogen-related emissions remain major challenges. In this study, combined numerical simulations and experiments were performed to investigate combustion characteristics and emissions in a two-stroke, low-speed ammonia/diesel dire
The language learning process by third age learners has recently become a field of interest for linguistic research. However, it has been studied mostly regarding psychological and cognitive considerations (stress, motivation, attention, memory, etc.), rather than according to language internal factors. The present study aims to provide a contribution by investigating the mastery of Italian gramma
With the development of low energy buildings in Northern European countries, conflicts regarding balancing daylight and energy performances in buildings arise. Therefore, design solutions that balance daylight and energy performances in buildings are needed. MKB Greenhouse is a newly-built, Miljöbyggnad Gold and Feby-Passive House certified, multi-family housing in Malmö, Sweden. Greenhouse also e
In a circular accelerator the closed orbit can be viewed as the mean position of particles in a beam. The closed orbit is perturbed by machine errors and can be manipulated by dedicated corrector magnets. This thesis introduces a linear algebra framework for closed orbit perturbation and correction, its implementation as a Python package and its use for three studies in HL--LHC: orbit corrector bu
The current climate crisis is pressuring policymakers to outline what a post-fossil economy might entail. In Norway, many have pointed towards the salmon farming industry as a central part of the country’s green transition. At the same time, the industry has shifted towards increasing use of feed imports from Brazilian soy plantations - the second largest driver of deforestation in the country. Ex
Tidigare forskning har visat på att sömn stärker minnen. Denna studie ämnade att utforska detta i en verklig situation genom att studera sömns effekt på vittnesmål. De 18 deltagarna fick se en video av en fiktiv misshandel och efter 12 timmar, där hälften av deltagarna var vakna under dagen och andra hälften av deltagarna sov under natten. De fick svara på ett minnestest om videon. Frågorna var inPrevious studies have shown that sleep strengthens memory. The current study has put this into a real-life context and study sleep’s effect on witness testimony. The 18 participants watched a video of a fictitious assault, and after a 12-hour delay, where half stayed awake during the day, and half slept during the night. They answered a questionnaire about the video, as a memory test. The question
Background: The response to the COVID-19 pandemic involved various lockdown measures, including school closures, which significantly impacted young populations, particularly in low-and middle-income countries (LMICs). Given the well-known protective effect of regular school attendance on sexual and reproductive health and rights (SRHR), reports of disrupted education, compromised SRHR, and an incr
