This study focuses on the characterization of NaCl-induced enhancement of H+ exchange catalysis and preparation of the renewable C6 platform chemical, 5-(hydroxymethyl)furfural (5-HMF), through dehydration of fructose and glucose, C6-sugars, utilizing a heterogeneous catalyst. The effect of a catalytic amount of NaCl was explored to enhance the H+ exchange of cation exchangers, characterized on th
BackgroundEliciting and understanding older persons’ descriptions of their resources for healthy ageing and the interaction of these resources with alcohol use and alcohol problems can facilitate health promotion. It can also inform clinicians when identifying areas of recovery capital that present risks and strength for older people seeking alcohol treatment. The objective of this study was to il

"Keltainen huone (Yellow Room)" recorded by 441 Hz Chamber Choir, conductor Anna Wilczewska in 2015 was released on a cd titled 'Modern Choral Masterpieces' in November 2015 on Dux Records (Poland).
The area in Södra Sallerup is, as far as we know, the only large-scale flint mining area in Sweden. Radiocarbon dates indicate that the flint was mined mainly during the Early Neolithic. It is clear, however, that the flint that was scattered throughout the area by the mining activity was used during later periods, even as late as the Viking and Medieval Periods.The large-scale mining during the E
Ett nytt moment har införts på de två nya civilingenjörsprogrammen i brandteknik och riskhantering vid LTH: ett spelmoment där studenterna ställs inför ett simulerat riskhanteringsscenario där de med begränsade resurser och osäkra framtidsutsikter är satta att hantera översvämningsrisker i en humanitär kontext. De får öva på att fatta beslut för att försöka undvika kris och hushålla med värdefulla
Undermedvetna könsstereotyper och fördomar påverkar jämställdheten i akademin, och även de som tror att de har en jämställd syn kan vara påverkade av dessa implicita bias. Kvinnor inom naturvetenskapliga ämnen både bedöms hårdare inom undervisning, bedömning, granskning och rekrytering och undervärderar sina egna akademiska förmågor vilket leder till en långsammare karriärsutveckling och i förläng
Baserat på befintliga nationella och kommunala föreskrifter, krav och råd som finns utspridda i olika dokument samt internationella rekommendationer om bästa praxis har omfattande riktlinjer sammanställts för hantering av cyklister vid vägarbetsplatser.
As climate has warmed significantly over past decades, numerous studies have confirmed a pattern of more frequent and more intense hydro-climate events across the globe, such as floods, heatwaves, and droughts. Analyzing the variability of climate events with reliable historical data records is one of the most direct approaches for understanding its patterns of change. The development of climate m
In the current global scenario, it is evident that global warming and climate change are primarily driven by emissions stemming from the utilization of fossil fuels. Yet, if we look around, most of what we see is made from or linked to fossil fuels and it clearly shows our over-dependency on fossil fuels and hence there is a significant need to develop alternate sources of energy and raw materials
Deep convolutional neural networks (CNNs) have been shown to predict poverty and development indicators from satellite images with surprising accuracy. This paper presents a first attempt at analyzing the CNNs responses in detail and explaining the basis for the predictions. The CNN model, while trained on relatively low resolution day- and night-time satellite images, is able to outperform human
Pure and hydrated deep eutectic solvents (DES) are proposed to form self-assembled nanostructures within the fluid bulk, similar to the bicontinuous L3 phase common for ionic liquids (ILs). Labelled choline chloride : urea : water DES were measured using small-angle neutron scattering (SANS), showing no long-range nanostructure. However, solutions of the surfactant AOT in this DES yielded scatteri
Deep eutectic solvents (DESs) are an emerging class of modern, often “green” solvents with unique properties. Recently, a deep eutectic system based on amphiphilic surfactant N-alkyl-N,N-dimethyl-3-ammonio-1-propanesulfonate (C12 & C14 sulfobetaine) and (1S)-(+)-10-camphor-sulfonic acid in the molar ratio 1:1.5 has been reported. Nanostructuring can be expected in this DES due to the nature of
Aim To investigate temporal trends in primary care visits, physiotherapy visits, dispensed non-steroidal anti-inflammatory drugs (NSAIDs) and opioids in knee osteoarthritis (OA) patients who have and have not undergone knee replacement. Methods We analysed 5665 OA patients from the Skåne Healthcare Register, Sweden, who underwent knee replacement between 2015 and 2019. Controls were OA patients wi
Exposure to per- and polyfluoroalkyl substances (PFAS) has been associated with reduced antibody response to childhood vaccinations. Previous studies have mostly focused on antibodies against diphtheria or tetanus, while fewer studies have assessed antibodies toward attenuated viruses, such as measles, mumps or rubella (MMR). Therefore, we set out to determine associations between prenatal and ear
