Cross section of the reaction 18O(p,γ)19F at astrophysical energies: The 90 keV resonance and the direct capture component

The observation of oxygen isotopes in giant stars sheds light on mixing processes operating in their interiors. Due to the very strong correlation between nuclear burning and mixing processes it is very important to reduce the uncertainty on the cross sections of the nuclear reactions that are involved. In this paper we focus our attention on the reaction 18O(p, γ)19F. While the 18O(p, α)15Nchannel is thought to be dominant, the (p,γ) channel can still be an important component in stellar burning in giants, depending on the low energy cross section. So far only extrapolations from higher-energ

Just art for a just city: Public art and social inclusion in urban regeneration

Summary. In this article, it is shown how cultural policy, and in particular public art, intersects with the processes of urban restructuring and how it is a contributor, but also antidote, to the conflict that typically surrounds the restructuring of urban space. The particular focus of the paper is on investigating how public art can be inclusionary/exclusionary as part of the wider project of urban regeneration. The first part of the paper examines examples in which public art intervention has attempted to generate inclusion. Subsequently, attention focuses more on examples in which the public art has been perceived as an aspect of cultural domination and has thus provoked resistance. Throughout, it is argued that the processes through which artworks become installed into the urban fabric are critical to the successful development of inclusion
