On the use of photobleaching to reduce fluorescence background in Raman spectroscopy to improve the reliability of pigment identification on painted textiles
No full textSubjecting a specimen of red lead watercolour paint on silk to photobleaching was demonstrated to be a simple means by which to engineer a reduction in the magnitude of the fluorescent background that was approximately exponential with time, with a corresponding improvement in the signal to noise ratio of the Raman spectrum, thus rendering the characteristic peaks more easily visible and allowing more confident identification of the pigment. However, relative heights of the Raman peaks obtained from the sample were seen to alter progressively as a result of irradiation, indicating that some component of the sample was undergoing degradation that may result in longer-term damage to a fragile historic artefact. It was also shown that crystals of the lead monoxide pigment massicot were present in the samples ofred lead on a painted silk artefact dating from 1750. It is concluded that this was either due to deliberate mixing of pigments by the artist, contrary to historic records, or as a result of the roasting techniques used to create red lead pigments at the time and not due to thermal degradation of the pigment during Raman analysis

Rooted in all its story, more is meant than meets the ear : a study of the relational and revelational nature of George MacDonald's mythopoeic art
No full textScholars and storytellers alike have deemed George MacDonald a great mythopoeic writer, an exemplar of the art. Examination of this accolade by those who first applied it to him proves it profoundly theological: for them a mythopoeic tale was a relational medium through which transformation might occur, transcending boundaries of time and space. The implications challenge much contemporary critical study of MacDonald, for they demand that his literary life and his theological life cannot be divorced if either is to be adequately assessed. Yet they prove consistent with the critical methodology MacDonald himself models and promotes. Utilizing MacDonald’s relational methodology evinces his intentional facilitating of Mythopoesis. It also reveals how oversights have impeded critical readings both of MacDonald’s writing and of his character. It evokes a redressing of MacDonald’s relationship with his Scottish cultural, theological, and familial environment – of how his writing is a response that rises out of these, rather than, as has so often been asserted, a mere reaction against them. Consequently it becomes evident that key relationships, both literary and personal, have been neglected in MacDonald scholarship – relationships that confirm MacDonald’s convictions and inform his writing, and the examination of which restores his identity as a literature scholar. Of particular relational import in this reassessment is A.J. Scott, a Scottish visionary intentionally chosen by MacDonald to mentor him in a holistic Weltanschauung. Little has been written on Scott, yet not only was he MacDonald’s prime influence in adulthood, but he forged the literary vocation that became MacDonald’s own. Previously unexamined personal and textual engagement with John Ruskin enables entirely new readings of standard MacDonald texts, as does the textual engagement with Matthew Arnold and F.D. Maurice. These close readings, informed by the established context, demonstrate MacDonald’s emergence, practice, and intent as a mythopoeic writer

Elliptic Analogues of the Macdonald and Koornwinder Polynomials
No full textPerhaps the nicest multivariate orthogonal polynomials are the Macdonald and Koornwinder polynomials, respectively 2-parameter deformations of Schur functions and 6-parameter deformations of orthogonal and symplectic characters,
satisfying a trio of nice properties known as the Macdonald “conjectures”. In recent work, the author has constructed elliptic analogues: a family of multivariate
functions on an elliptic curve satisfying analogues of the Macdonald conjectures, and degenerating to Macdonald and Koornwinder polynomials under suitable limits. This article will discuss the two main constructions for these functions, focusing on the more algebraic/combinatorial of the two approaches
