Evolution of microstructure, texture and grain boundary character distribution of potassium doped tungsten fibers annealed at variable temperatures

The effect of the annealing temperature on the microstructure and grain boundary character distribution of potassium doped tungsten fibers made of drawn wire was investigated by Electron Backscatter Diffraction. Samples, with a diameter of 148.7 μm, in the as-received condition and annealed at 1300, 1600, 1900, 2100 and 2300 °C were analyzed at the center of the transversal sections. Up to 1900 °C, a uniform microstructural coarsening and primary recrystallization followed by normal grain growth was observed. Between 1900 and 2100 °C abnormal grain growth took place. The strong texture (<110> parallel to the drawing axis) remained present in all conditions. With increasing the annealing temperature, the low angle grain boundary fraction increased at the expense of high angle grain boundaries while the amount of coincidence site lattice boundaries reached its maximum at 1600 °C. At this temperature, the most resistant configuration of triple junctions against intergranular crack propagation was obtained

Real-World Applications for Virtual Fences – What Are Potential Benefits for Conservation?

Livestock grazing can enhance biodiversity and ecosystem services in agricultural landscapes. In many parts of Europe, however, grazing has lost its importance, especially in the dairy sector. Large proportions of permanent grassland have been converted to arable land or intensified by fertilization and frequent defoliation. The disappearance of large herbivores and extensively grazed pastures contributes to the loss of structural, functional and biological diversity and ecosystem services. Modern technologies, which circumvent the cost- and labour-intensive installation of physical fences, could facilitate a precise spatio-temporal management of livestock and promote grazing. We reviewed the literature on the state-of-the-art of virtual fencing, focusing on the prospects of these technologies to enhance environmentally-friendly livestock farming. Novel virtual fencing technologies are expected to entail various ecological benefits, but this has rarely been tested in practice. Future experiments not only need to increase sample sizes and study periods to evaluate the long-term effectiveness of virtual fencing, but also need to be specifically designed for answering questions of conservation interest. Virtual fences have the potential to reconcile agronomic with ecological demands and bring livestock back into the landscape, but whether they will actually find broad application depends on further multidisciplinary research on animal welfare, agronomic, social and legal aspects

Why we need a public understanding of social science

Copyright © The Author(s) 2023. Who is licensed to make knowledge claims about society? A more diffuse group of individuals are afforded the status of legitimate speakers on society in the public sphere than is the case when the questions relate to the expertise of the natural sciences. We draw on the concept of the ‘locus of legitimate interpretation’ and the sensibilities of Collins and Evans’ Studies of Expertise and Experience programme to help make sense of these issues. The social sciences are not the natural sciences, and one key difference is their relationship with publics. The social sciences are intrinsically entangled, at both the level of the research question and the research subject/object, with public knowledge, the knowledges of publics and public interests. We therefore outline what these differences might mean for a serious, distinct and purposive Public Understanding of Social Science programme and how this differs from current work in the Public Understanding of Science.The author(s) received no financial support for the research, authorship and/or publication of this article

Science blogging: Networks, boundaries and limitations

There is limited research into the realities of science blogging, how science bloggers themselves view their activity and what bloggers can achieve. The ‘badscience’ blogs analysed here show a number of interesting developments, with significant implications for understandings of science blogging and scientific cultures more broadly. A functioning and diverse online community (with offline elements) has been constructed, with a number of non-professional and anonymous members and with boundary work being used to establish a recognisable outgroup. The community has developed distinct norms alongside a type of distributed authority and has negotiated the authority, anonymity and varying status of many community members in some interesting and novel ways. Activist norms and initiatives have been actioned, with some prominent community campaigns and action. There are questions about what science blogging—both in the UK and internationally—may be able to achieve in future and about the fragility of the ‘badscience’ community. Some of the highly optimistic hopes which have been associated with science blogging have not been realised. Nonetheless, the small group of bloggers focused on here have produced significant achievements with limited resources, especially when one considers this in the context of community values as opposed to some of the expectations attached to science blogging within scientific cultures more broadly. While the impacts of this science blogging community remain uncertain, the novel and potentially significant practices analysed here do merit serious consideration
