At a geological time-scale, seas rise aloft and mountains crumble. We are currently in the middle of a debate on whether—in order to acknowledge the pervasive and geologically significant traces of human action on the planet—our present era should be labelled the “Anthropocene”, and if so, what would be the cut-off date for the commencement of that era. At the same moment, we are already contempla
Nanowire (NW) optoelectronic and electrical devices offer unique advantages over bulk materials but are generally made by contacting entire NW arrays in parallel. In contrast, ultra-high-resolution displays and photodetectors require electrical connections to individual NWs inside an array. Here, we demonstrate a scheme for fabricating such single NW vertical devices by contacting individual NWs w

UNLABELLED: The aim of this systemic review and meta-analysis was to examine the differences in caesarean section rates across European regions and at a country level by utilizing the Robson classification system. The study has compared caesarean rates across European regions using the Robson classification to identify the drivers of caesarean section use. This review shows significant variations
Anion exchange membranes (AEMs) carrying N-spirocyclic quaternary ammonium cations generally have a high alkaline stability because the unstrained ring conformations of this type of bicyclic cation. Here, we have prepared a series of N-spirocyclic quaternary ammonium ionenes (spiro-ionenes) using a diphenyl-functionalized monomer with a di-N-spiro-isoindolium moiety containing two N-spiro cations.
The family of methodologies and approaches used and developed by the systemic design community has several characteristics that could play a vital role in supporting collective visioning and concerted action for sustainability transitions. It offers heuristics for bridging scales and domains, and tools for constructing spaces of joint reflection, visioning and decision-making. These methodologies
Extruded mortar joints, resulting from suboptimal workmanship in bricklaying, bridge air gaps within cavity external walls. This phenomenon establishes a connection between brick masonry claddings and adjacent layers (such as insulation or weather-resistive barriers), inadvertently intensifying water penetration due to wind-driven rain (WDR) loads. This study utilises a probabilistic analysis in c
In Sweden, cavity walls constructed with autoclaved aerated concrete (AAC) inner leaves and clay brick outer leaves were a common design choice during the 1950s to 1970s. These walls often result in relatively extensive heat losses, leading to reduced indoor thermal comfort. Further, moisture-related issues like frost damage and interior dampness are reported for this wall type. This indicates the
Neuroblastoma (NB) is the most common cancer in infancy with an urgent need for more efficient targeted therapies. The development of novel (combinatorial) treatment strategies relies on extensive explorations of signaling perturbations in neuroblastoma cell lines, using RNA-Seq or other high throughput technologies (e.g. phosphoproteomics). This typically requires dedicated bioinformatics support
Objective Elite para athletes report a high incidence of sports injuries. Research suggests that athletes’ strategies to manage adversities may influence the sports injury risk, but knowledge about para athletes’ coping behaviours and their association with injuries is limited. The aim was to describe the distribution of coping behaviours in Swedish elite para athletes by sex, age, impairment, spo
Vardagstrycket på UB i Lund innehåller många priskuranter. Här ligger fokus på priser för död och begravning under tidigt 1900-tal. Begravningskostnader motsvarande en månadslön för en arbetare innebar inga extravaganser. En påkostad begravning kunde däremot handla om summor motsvarande flera årslöner för en arbetare.
In honor of the 125th year of The Scandinavian Journal of Economics, this paper highlights some of the influential research published here in the last 25 years, considers current trends in the field, and describes a view of the future of this journal in the overall economics research ecosystem.
A large-scale purification method was developed for producing paclitaxel, to guarantee high purity and yield from plant cell cultures. The complete method for mass production was a simple and efficient procedure, for the isolation and purification of paclitaxel from the biomass of Taxus chinensis, consisting of solvent extraction, synthetic adsorbent treatment, and two steps of precipitation, foll
The development of replacing human organs with those from genetically modified pigs holds immense potential for alleviating the shortage of organs necessary for patients in need of transplants. This medical advancement is also accompanied by significant social changes, including the emergence of a bioeconomy, new modes of biotechnology governance, altered human-animal relations and increased publi
Positioning Polymer Electrolyte Fuel Cells (PEFCs) in the market depends on substantial advances that start from a deep knowledge concerning the influence of operating parameters, such as temperature-sweep and high-current density. In the present study, a comprehensive analysis of the impedance behavior of a single PEFC via Electrochemical Impedance Spectroscopy (EIS) was carried out in order to u
The purification of crude (60.89% pure) paclitaxel was developed for high purity and yield. Several solvent systems, including methanol (MeOH), acetone, tetrahydrofurane, n-hexane, and water, were evaluated for precipitation efficiency. The best results were obtained using a mixture of MeOH and water, which was very effective at removing polar impurities, yielding a precipitate with 90.87% purity.
Saccharide–fatty acid esters, important biobased and biodegradable emulsifiers in foods, cosmetics, and pharmaceuticals, were produced with high yields and productivity via immobilized Rhizomucor miehei lipase-catalyzed esterification in solvent-free systems at 65 °C. Preliminary experiments demonstrated high rates of reaction occurred in the presence of acetone near or above its boiling point, du
