Trimetallic nickel–iron–molybdenum oxides are excellent electrocatalysts for alkaline water electrolysis despite experiencing severe molybdenum dissolution. While the impact of molybdenum on fresh samples is well-understood, its substantial loss during operation without compromising performance presents a unique puzzle. Here, we show that the initial presence of molybdenum induces the formation of
This study investigates the influence of polypropylene fibres (PF) on concrete performance across a finely resolved dosage spectrum (0.0–2.0% by cement mass, in 0.1% increments) using 2,100 laboratory specimens. The experimental programme evaluated compressive strength, tensile strength (flexural and splitting), modulus of elasticity, and water penetration depth. Predictive modelling was conducted
Trelleborg fortresses – the dream architecture of the Viking Age. In 1934, few decades after the idea of the existence of Jomsborg had been critically rejected, a geometric Viking fortress was surprisingly discovered on Zealand, named after the site, a so called Trelleborg fortress. This was followed by the search for more fortresses all over Scandinavia, a search that is still ongoing. Their ramp
This article elaborates on the embodiment of heritage via dressing practices in several rural and urban Nordic communities in the United States. Getting dressed is a shared human practice that we engage in and repeat most days, and for special occasions, traditional dress, or folk costume, comes into particular focus. I approach dressing in folk costume as a “situated embodied practice,” a mode of
Drawing on actor-network theory and theories of performance, this article discusses gift-giving as an expansive form of materializing relationships and delimiting boundaries between nations, regions, organizations and individuals in the wake of migration. Initially, I discuss gift-giving as a way of materializing relationships and building networks. Thereafter, I map out the social life of the Vär
We reviewed papers on optimal conjunctive use of surface and groundwater (GW) with application in dry regions. Selected papers from the last 25-year period were reviewed using the PRISMA method. We show that with increasing scarcity of water, objectives of models developed for optimal conjunctive use have become more environmentally and socially oriented. About two-thirds of the studies are dedica
Over the past century, Syria and the broader Middle East and North Africa (MENA) region have undergone profound demographic and economic transformations, yet they remain marked by deep regional, ethnic, and gender-based inequalities. These divisions have shaped development trajectories and contributed to social fragmentation, while successive waves of migration carried these dynamics abroad, from
This paper investigates the magnitude and drivers of ethnic and religious disparities in Female Labor Force Participation (FLFP) in Syria. Using census data and the Gelbach decomposition method, the analysis reveals substantial FLFP gaps across groups, reaching up to 18 percentage points. To understand the factors underlying these gaps, the analysis exploits the heterogeneity in economic developme
Developing a robust decision analysis framework for selecting appropriate building envelope assemblies is essential to ensure moisture safety, energy efficiency, and sustainability. Recently, Bayat Pour et al. introduced the inutility decision analysis (IDA) method, which integrates moisture safety criteria with sustainability considerations, including economic and environmental aspects. This stud
By combining ultrashort laser pulses with PEEM, time-resolved photoemission electron microscopy (TRPEEM) provides a powerful approach for investigating ultrafast charge carrier dynamics with simultaneous femtosecond temporal resolution and nanometer spatial precision. It has evolved into a versatile methodto study a wide range of phenomena, including charge carrier dynamics, surface plasmons, scat
Har du som lärare funderat på vad motivationen betyder för elevernas språkinlärning? Har du funderat på om olika aktiviteter i klassrummet kan skapa eller öka elevernas motivation för att lära sig språk? Detta är ett område som inte beforskats så mycket som man kanske tror, trots att skolämnet moderna språk brottas med avhopp och bristande motivation. Vi beskriver här ett forskningsprojekt som und
Migratory songbirds have an internal circannual genetic programme that controls the timing and extent of migratory flight activity, as demonstrated by experiments with birds held in cages. We used multisensor data loggers to record the timing and duration of all migratory flights during the annual cycle of 15 free-living individuals of red-backed shrikes Lanius collurio. Annual actograms unexpecte
