Froth flotation is a common unit operation used in mineral processing. It serves to separate valuable mineral particles from worthless gangue particles in finely ground ores. The valuable mineral particles are hydrophobic and attach to bubbles of air injected into the pulp. This creates bubble-particle aggregates that rise to the top of the flotation column where they accumulate to a froth or foam
A Slow Sand Filter (SSF) consists of biofilm attached to saturated packed sand with supernatant water on top, through which water flows by gravity. SSFs are used in the production of drinking water to improve water quality and remove pathogens, and, as they use biological filtration via the microbes present in the biofilm, they are simple and cheap to construct. A drawback of SSFs is that the diff
Narrativ medicin och medicinsk humaniora är två närliggande akademiska fält som båda på olika sätt möjliggör interdisciplinära möten mellan medicin och humanvetenskaperna, och som är på framväxt sedan ett par decennier både internationellt och i Sverige. De två fälten har olika fokus, men också många överlappande intressen. I den här artikeln tecknas konturerna av medicinsk humaniora och narrativ
The circular economy (CE) challenges the traditional linear economic model by emphasizing the importance of resource efficiency, recycling, and regeneration in society. However, the role of gender in CE practices remains underexplored. This article presents a systematic literature review on how gender dynamics intersect with CE, highlighting the implications of gendered labor distribution, access
Intersectional multilevel analysis of individual heterogeneity and discriminatory accuracy (I-MAIHDA) is an innovative approach for investigating inequalities, including intersectional inequalities in health, disease, psychosocial, socioeconomic, and other outcomes. I-MAIHDA and related MAIHDA approaches have conceptual and methodological advantages over conventional single-level regression analys
Viking Age silver is a useful tool for tracing various aspects of the society. Contact networks, trade organization, society structure, economic variation etc. This paper concentrates on the so-called Permian rings, which appear in Scandinavian silver hoards from Early Viking Age. Their main concentration is, however, in the regions west of the Ural Mountains in Russia. As the rings found in Russi
Source code analysis is ubiquitous in the development of software tools, for example in compilers to detect compile-time errors and possible optimizations, inIDEs to provide interactive coding assistance, and in stand-alone analysis tools todetect bugs. There are several techniques that have been developed to help theanalysis developer, including one called Reference Attribute Grammars (RAGs).With
Unless you are a specialist or watch a lot of obscure YouTube videos you have probably never heard of He II or superfluid helium. This substance, a unique liquid form of the element helium, is produced and used in multi-ton quantities to enable much of modern science. Altogether, He II is at the heart of more than a dozen large scale scientific facilities world-wide representing an investment of t
This chapter analyses the role that 'ordre public' and morality exceptions can play in the granting of patents on inventions in the field of human germline editing and the consequences of this policy option. In order to provide the context for such an analysis, the chapter will, first, provide an overview of the current patent landscape for relevant genome editing technologies, drawing attention t
Over the past fifteen years, Hip Hop–based education has gained ground in academic literature, especially so by building on the educational tradition and gospel of Each One Teach One. A contribution to this scholarly discussion is the Scandinavian attempt to analytically tie Hip Hop education to perspectives on learning and pedagogy that traditionally derives from popular movements of the twentiet
The activities of cluster initiatives operating as systemic intermediaries and supporting networking activities have been discussed in prior studies. We integrate insights from the cluster theory and the literature on sustainability transitions to study the activities of clusters acting as systemic intermediaries in the different phases of the development of a forest-based bioeconomy, namely (1) p
This study aimed examin the factors associated with the uptake and non-acceptance of COVID-19 vaccine booster doses among healthcare workers (HCWs) in South Africa. We used a mixed-methods design with data from a web-based self-administered survey followed by semi-structured in-depth interviews (IDIs) with selected participants. Of the 6235 HCWs included in our analysis who had fully vaccinated, 3
Motoric eating difficulties affecting the ability to eat according to established norms may result in loss of autonomy, reduced food intake and decreased social interaction. Finger food meals may affect the ability to eat independently and were therefore compared to regular meals for older adults >65 years with major motoric eating difficulties. In this pilot study the screening instrument MEOF-II
Arsenic is highly toxic and a significant threat to human health, but certain bacteria have developed defense mechanisms initiated by AsIII binding to AsIII-sensing proteins of the ArsR family. The transcriptional regulator AfArsR responds to AsIII and SbIII by coordinating the metalloids with three cysteines, located in a short sequence of the same monomer chain. Here, we characterize the binding
