This study reports the synthesis and characterization of heterogeneous acid catalysts derived from rice husk biochar, modified by sulfonation and Ce(NO3)3·6H2O (cerium (III) nitrate hexahydrate) impregnation, for fatty acid esterification using methyl acetate as a glycerol-free reaction route. The research aims to valorize agricultural residues as renewable and sustainable precursors for solid aci
A number of recent experiments have indicated that magnetic nanoparticles can become locally hotter than their nonmagnetic surroundings during induction heating. While such nanoscale hotspot-effect is particularly attractive for applications within biomedicine and catalysis, its existence is a topic of scientific controversy. To address this, we here present simultaneous measurements of the intern
The axon initial segment (AIS) is a specialized neuronal microdomain that serves as a physical diffusion barrier, separating the axon from somatodendritic compartments. As a highly plastic structure, the AIS dynamically regulates neuronal excitability and contributes to circuit homeostasis. Recent advances in super-resolution imaging and disease modeling have expanded our understanding of its role
Presented at the International VISURF Nordic-Baltic Colloquium Visions of Residential Futures (Gothenburg, 2011), part of a NordForsk-supported research network exploring housing transformation and urban living, this contribution introduces Dérive – Lerum, an urban and architectural proposal developed within Europan 10, a European competition platform for innovative housing and urban development.T

Presented at the Europan Inter-Sessions Forum (2021), an international platform bringing together winning teams, municipalities, and researchers to discuss the transition from competition ideas to implementation processes, this contribution focuses on Lerum E10, a collaborative project by Marco Pusterla and Jesús Mateo, developed within Europan 10, a European competition and research platform for
Sweden is renowned for its centralised wage bargaining system, which has been studied from the point of view of inflation, wage differentials and unemployment. This article studies media coverage of wage bargaining rounds in the 1950s–1960s and in the 2000s–2010s to investigate the social understanding of what the wage bargaining institutions are supposed to do. The results indicate that the opera

Gambling has become a prominent feature of Central Asia's shifting economies, reshaping social life and governance across the region. While some states maintain prohibitions, others, including Kazakhstan, have legalized gambling as a tool for revenue generation and tourism development. This expansion, however, has produced significant social costs, including family disruption, rising indebtedness
Aims: Identifying reliable biomarkers is crucial for addressing diagnostic uncertainty and prognostic stratification in amyotrophic lateral sclerosis (ALS). This systematic review and meta-analysis aimed to integrate recent evidence on blood and cerebrospinal fluid (CSF) biomarkers.Methods: We searched studies published between January 1, 2019, and March 25, 2025, investigating blood or CSF biomar
Metabolic syndrome (MetS) is a cluster of cardiovascular risk factors, including abdominal obesity, insulin resistance, dyslipidemia, and hypertension. Its association with venous thromboembolism (VTE) has been inconsistently reported. We investigated the association between MetS and VTE, and the influence of sex and abdominal obesity. We included 12,788 middle-aged and older adults from the re-ex
OBJECTIVES: To identify the lowest sensitivity and specificity that physicians and the general population consider acceptable for medical artificial intelligence (AI), relative to current human performance.METHODS: In a nationwide, cross-sectional survey in Sweden, 2025, random samples of 500 physicians and 500 adults from the general population were mailed a questionnaire presenting three vignett
Marine invertebrates and seaweeds of the lagoons and reefs have always been an important source of food and raw materials for the people of Oceania. I examine the gathering of these organisms in both contemporary and more ancient contexts, and according to a gender-based division of tasks. It is argued that although men’s fishing has been well documented, until recently women’s inshore fisheries,
The current framing of AI-driven technologies situates them as solutions to a looming care crisis. However, this overlooks informal caregivers' key role to current State budgetary deficits impacting healthcare services happening in Europe. As States increasingly rely on informal caregivers to provide care before the necessary involvement of healthcare services, there is already well-established re
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogenesis is shaped not only by viral entry mechanisms but also by interactions with host and microbial factors. The viral spike (S) protein can bind Gram-negative bacterial lipopolysaccharide (LPS), a driver of hyperinflammation in severe COVID-19. How viral evolution over the years alters this interaction remains unclear. Here, we i
