Incorporation of Carbon Nanoparticles in Polyaryletherketone Matrices for High Performance Liquid Chromatography Applications
No full textPolyaryletherketone (PAEK) plastics are an option for rotary shear valves in High Performance Liquid Chromatography (HPLC) applications owing to their high strength, thermal resilience, and chemical inertness. In this study, the effects of adding carbon nano particles at a 1% weight loading to 30% carbon fiber loaded PAEK plastics via a simple melt blending process were explored and compared to neat PAEK blends. Experimental blends were tested for their Young’s modulus, relaxation under sustained load and temperature, yield strength, and internal defects. It was found that OH-functionalized graphene nano particles increased the moduli of PEEKCF30 and PEKEKKCF30 by 10.8% and 4.7% respectively. These results were considered statistically significant by hypothesis tests for a 95% confidence level. Further, a neat PEKKCF30 blend was determined to have a 30.2% increase from the neat PEEKCF30 blend and was also statistically significant. Under sustained load at ambient temperature, it was found that graphene oxide reduced the relaxation force by 10% in a PEEKCF30 blend and the neat PEKKCF30 blend reduced this force by 36% while both were statistically significant. Under sustained load at elevated temperatures, the PEKKCF30 blend performed well compared to neat PEEKCF30 at all temperatures with a detriment at 90C of only -1.2%, and improvements of 7.6% & 3.1% at 110C, & 130C respectively. Yield strength calculations revealed a 10% and 15% improvement for PEEKCF30 functionalized graphene and neat PEKKCF30 respectively. Finally, microscopic analysis revealed void formation and contaminants were more common in blends with carbon nano particles. From this screening analysis, the neat PEKKCF30 base polymer and OH-functionalized graphene additive are recommended for further exploration.M.Eng
A little-known contribution to the Lulliste-Ramiste dispute. Jean Galli de Bibiena’s Mémoires et aventures de monsieur de *** (1735)
No full textDisputes concerning opera, even more so than literary polemics, have a special importance for the historiographer in illustrating how a given piece was perceived by contemporary audiences. As Paul-Marie Masson puts it, ‘By the way a work is attacked or defended, authors understand better what the author wished to achieve and what the public expected of him’. The Lullistes’ attacks, which were directed as much at Rameau’s person as at his music, came in many different guises. In addition to open letters to the press, they included derogatory poems, among them Jean-Baptiste Rousseau’s much-quoted ‘Distillateurs des accords baroques’ and the satire Marsias allégorie, which, though anonymous, was widely believed to be the work of the poet and librettist Pierre-Charles Roy, ringleader of the Lullistes
Classical and non-classical Schottky groups
Full text linkThis thesis looks at two disparate problems relating to Schottky groups, and in particular what it means for a Schottky group to be classical or non- classical.
The first problem focusses ofl the uniformization of R.iemann surfaces using Schottky groups. We extend the retrosection theorem of Koebe by giving conditions on lengths of curves as to when a Riemann surface can be uniformized by a classical Schottky group.
The second section of this thesis examines a paper of Yamamoto ([40]), which gives the first example of a non-classical Schottky group. We firstly expand on the detail given in the paper, and then use this to give a second example of a non-classical Schottky group. We then take tIns second example and generalise to a two-variable family of non-classical Schottky groups
From digital technologies to new economics in banking: how to drive the future of digital money and data information knowledge
No full textThe chapter aims to understand to what extent some factors, namely technology, regulation, customer habits, etc, are going to influence institutional changes and lead to economic and social consequences in the industry. This chapter is organized as follows: on the one
hand, it offers insights on some of the hype storm words, such as digitalization,
FinTechs, open banking, embedded finance, banking-as-a-service, and decentralized finance, that are creating a twisted picture of the digital banking industry
(Section 3.2). On the other hand, by linking the dots, this chapter will outline the most interesting implications for the industry, incumbents, FinTech
firms and those banks that have undertaken a deep strategic transformation
(Sections 3.3 and 3.4). Finally, Section 3.5 presents the main conclusions
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
