This paper studies the underlying mechanisms to binder phase lamella formation (in WC/WC grain boundaries) in hardmetal inserts used in face turning. A distribution of lamellae orientations has been quantified for used turning inserts as well as pristine inserts and coupled to the direction of the applied stress, calculated by FEM. Furthermore, more detailed FEM calculations on the micro scale hav
Transport energy conservation research in urban transport systems dates back principally to the Organization of the Petroleum Exporting Countries’ (OPEC) “Arab Oil Embargo” (1973–1974) and the Iranian revolution (1979), when global oil supplies became threatened and costs rose steeply. Two subsequent Gulf Wars (1991 and 2003) highlighted the dangerous geo-political dimensions of Middle-Eastern oil
Many democracies find it difficult to act swiftly on problems such as climate change and biodiversity loss. This is reflected in long-standing debates in research and policy about whether democratic practices are capable of fostering timely, large-scale transformations towards sustainability. Drawing on an integrative review of scholarly literature from 2011 to early 2021 on sustainability transfo
The connection between branch and trunk in a tree must be strong enough to transfer all loads acting on the branch, and it is well known that such branch-stem connections are indeed very strong. In this paper, X-ray computer tomography is employed to investigate the local fibre orientation in the close surrounding of a knot in a Norway spruce specimen to better understand the origins of the mechan
Background: Topical probiotics have been suggested as a treatment option for allergic rhinitis, as they may skew the immune response towards a beneficial type-1 non-allergic profile. So far observations in man have exclusively involved oral intake. The aim of this study was to examine whether a topical/nasal administration of a probiotic assemblage (PA) affects quality of life, symptoms and signs
This collective volume contributes to the conceptual understanding of Arab youth and their relationship to politics by making explicit how civic engagement in seemingly ‘apolitical’ fields can be conceived as a form of political activism. Using the analytical tools of practice theory, ‘youth’ is reconceptualized as a generational practice of politics, meaning a ‘competent performance’ of shared kn
Investigation into youth activists across different fields of social and political engagement reveals a shared political subjectivity and collective self-conceptualization. In assessing Lebanese youth civic and political activism from the perspective of the youth themselves, placing their own subjectivity centrally in the analytical framework, this paper reveals an imagined community, the Civil So
Exercise is considered to be a "medicine" due to its modulatory roles in metabolic disorders such as diabetes and obesity. The intensity and duration of exercise determine the mechanism of energy production by various tissues of the body, especially by muscles, in which the requirement for adenosine triphosphate (ATP) increases by as much as 100-fold. Naturally, athletes try to improve their exerc
As in most cultural contexts and theoretical conceptualizations of peacebuilding, the fulfilment of justice and the sustainment of peace are intimately related in the Arab-Islamic frame of reference. In the Qur’an and Islamic philosophy, there is a direct correlation between establishing a just social order and the notion of peacebuilding (Abu-Nimer 2006). Guidelines are set forth for building a so
We studied ice-nucleating abilities of particulate emissions from a modern heavy-duty diesel engine using three different types of fuel. The polydisperse particle emissions were sampled during engine operation and introduced to a continuous-flow diffusion chamber (CFDC) instrument at a constant relative humidity RHwater=110 %, while the temperature was ramped between −43 and −32 ∘C (T scan). The t
The focus for this study is the collection of mosaic-floors that adorn the entrances, fauces, to atrium-houses around Pompeii. The aim is to further our understanding of the Roman view of transitional spaces, in this case the private house-entrance between the inside and the outside world. Contemporary approaches to Pompeian studies regard space and décor as closely intertwined components, which s
In 2013, the drinking water for one-third of the households in Ronneby, Sweden, was found to be contaminated by perfluorinated alkyl substances (PFAS, >10,000 ng/L) from Aqueous Film Forming Foam (AFFF). In utero PFAS exposure can influence birth weight, but little is known about the effects at very high levels. This study aimed to examine the association between in utero PFAS exposure and birth w
Contributions in this thematic issue focus explicitly on citizens and their online engagement with European politics. For social media research in the European Union, citizens remain an understudied actor type in comparison with political elites or news organizations. The reason, we argue, is four key challenges facing social media research in the European Union: legal, ethical, technical, and cul
