The effect of the cation composition on the synthesis and properties of ultramarine blue
No full textThe effect of potassium cations on the shade of the ultramarine blue pigment system has been investigated through analysis of commercial materials, ion exchange reactions of sodium-form ultramarine blue and a detailed study of the effect of adding potassium sources to ultramarine precursor mixtures. Incorporation of potassium cations has the result of producing redder shade material and the replacement of around 20% of the sodium in the standard reaction mixture produces the optimised red-shade pigment. The origin of this hue control may be a direct effect, involving interaction of potassium ions with the ultramarine blue structure and the S3? chromophore or, more likely, potassium ions aids the stabilisation of S3? within the sodalite framework during the ultramarine blue formation process. In the commercial process, the role of the potassium source in red shade formation may be performed by the incorporation of potassium-rich feldspar additives

The contribution of symptoms of post-traumatic stress disorder (PTSD), health anxiety and intolerance of uncertainty to distress in Ménière's disease
No full textThis study assessed whether symptoms of post-traumatic stress disorder (PTSD), health anxiety, and intolerance of uncertainty were associated with distress in members of the Ménière's Society (n = 800), and compared the extent of anxiety, depression, intolerance of uncertainty and health anxiety with a healthy control group (n = 484). PTSD symptoms were associated with anxiety, depression, and handicap. Health anxiety was associated with anxiety and depression. Intolerance of uncertainty was directly associated with anxiety; its association with depression and handicap was mediated by PTSD symptoms. The Ménière's group reported more anxiety, depression, and health anxiety than the control group, but were not more intolerant of uncertainty. More than half of the Ménière's group reported experiencing partial or full PTSD symptoms. As PTSD, health anxiety and intolerance of uncertainty are modifiable with psychological treatment, we advise that clinicians should screen patients with Ménière's disease who are particularly distressed

Fabrication of nanocrystalline aluminium islands using double-surface anodization
No full textWe report a technique of fabrication of Al nanoislands of dimensions as small as 3 nm. Thin Al foils were anodized from both the surfaces under conditions suitable for the growth of porous alumina. Unanodized Al nanoislands were thus formed at the interpore regions and characterized by transmission electron microscopy. The method allows control over the distribution and the size of the nanoscale islands through the parameters of the anodization process, and automatic passivation by surrounding alumina
Victimised Actors and Despotic Directors: Clichés of Theatre at Stake in Beckett's 'Catastophe'
No full textThe essay focuses on 'Catastrophe', one of the last plays Beckett wrote, which the author sees as almost the culmination of his idea of the theatre. This 1982 play is the epitome of the demanding performance Beckett's theatre requires from the actors and of the great freedom and power paradoxically it gives them. By undermining, with a great sense of irony, himself and his working method, but even more radically the directorial function itself, in this play, Beckett, the celebrated 'tyrant-director' reveals the sole concrete reality of the production: that it is the realm of the actor
A comparative case study of coordination mechanisms in Design and Build BIM-based projects in the Netherlands
No full textBIM implementation can affect the project coordination mechanisms in unexpected ways, even in widely-applied project procurement structures. Apart from the chosen procurement approach, the BIM technology and the distribution of roles in the project team influence and shape the project coordination. This paper aims to explore the emerging coordination structures and processes from BIM implementation in design-build procurement. An exploratory comparative case study has been undertaken. The findings included two main coordination mechanisms: a centralized and decentralized structure and a hierarchical ver-sus participative decision-making processes. These two patterns subsequently open a debate about the rela-tions between BIM implementation and business models in AEC and particularly the emergence of specialized all-around BIM firms versus BIM-knowledgeable engineering firms.Accepted Author ManuscriptDesign & Construction Managemen
