Usability of clay mixed red mud in Hungarian building material production industry

The naturally occurring radionuclide (²²⁶Ra,²³²Th and⁴⁰K) content of building Materials (NORM) contributes to the total radiation dose experienced by humans. In this survey 27 clay and 68 red mud samples were surveyed with gamma spectrometry and screened according to European Basic Safety Standards (BSS) I-index. It was found that average I-index of clays was 0.6 (0.4–0.8) less than the I-index of 1, which makes them suitable for building material production. The average I-index of red mud 2.3 (1.3–3.0). The maximal mixing ratio of red mud was calculated, varied between 12 and 39 %, with 23 % average.

'A Romanian Perspective on Brian Friel's Translations'

Based on the premise that the history of the representation in drama of the Ulster "Troubles" has been characterised by a move from direct to metaphorical engagement, this paper seeks to explore the signficance of Brian Friel's Translations as a "Troubles Drama" with reference to a production of the play I directed for the Hungarian Theater of Cluj in the Fall of 2001. Interpreting a play about language in a language other than the one in which it was originally written proved to have many implications for the rehearsal process and led me to experiment with the image theatre techniques of Augusto Boal. The nature of Cluj/Kolozsvar as a bi-lingual city added to the complexities of the process, as did my own status as an English-speaking director in a Hungarian-speaking environment. The extraordinary neautre of the wider geopolitical context at the time of the production proved to be the final ingredient in what became an exceptional empirical process of discovery. The discussion of the particular production is placed in the wider context of an exposition of a theory of "cultural gravity" as an alternative to "liminality" in helping to assess the cultural signficance of geopolitical boundaries.

Liquid-liquid miscibility and volumetric properties of aqueous solutions of ionic liquids as a function of temperature

The volumetric properties of seven {water + ionic liquid} binary mixtures have been studied as a function of temperature from (293 to 343) K. The phase behaviour of the systems was first investigated using a nephelometric method and excess molar volumes were calculated from densities measured using an Anton Paar densimeter and fitted using a Redlich-Kister type equation. Two ionic liquids fully miscible with water (1-butyl-3-methylimidazolium tetrafluoroborate ([CCIm][BF]) and 1-ethyl-3-methylimidazolium ethylsulfate ([CCIm][EtSO])) and five ionic liquids only partially miscible with water (1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([CCIm][NTf]), 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([CCIm][NTf]), 1-butyl-3-methylimidazolium hexafluorophosphate ([CCIm][PF]), 1-butyl-3-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([CCPyrro][NTf]), and butyltrimethylammonium bis(trifluoromethylsulfonyl)imide ([N][NTf])) were chosen. Small excess volumes (less than 0.5 cm · mol at 298 K) are obtained compared with the molar volumes of the pure components (less than 0.3% of the molar volume of the pure ionic liquid). For all the considered systems, except for {[CCIm][EtSO] + water}, positive excess molar volumes were calculated. Finally, an increase of the non-ideality character is observed for all the systems as temperature increases. © 2009 Elsevier Ltd. All rights reserved.

DRAKULA HALÁLA (1921): The Cinema's First Dracula.

This essay covers the history of Károly Lajthay’s Hungarian film Drakula halála (1921), the cinema’s first adaptation of Bram Stoker’s novel Dracula. The essay attempts to construct a production history of the film, as well as to create an accurate list of cast members and key filming locations. As Drakula halála is lost, the essay also features the very first English translation of an extremely rare 1924 Hungarian novella based on the film, which offers much insight into its narrative.

Density and viscosity of several pure and water-saturated ionic liquids

Densities and viscosities were measured as a function of temperature for six ionic liquids (1-butyl-3-methylimidazolium hexafluorophosphate, 1-butyl-3-methylimidazolium tetrafluoroborate, 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, 1-ethyl-3-methylimidazolium ethylsulfate and butyltrimethylammonium bis(trifluoromethylsulfonyl)imide. The density and the viscosity were obtained using a vibrating tube densimeter from Anton Paar and a rheometer from Rheometrics Scientific at temperatures up to 393 K and 388 K with an accuracy of 10-3 g cm-3 and 1%, respectively. The effect of the presence of water on the measured values was also examined by studying both dried and water-saturated samples. A qualitative analysis of the evolution of density and viscosity with cation and anion chemical structures was performed. © The Royal Society of Chemistry 2006.

Thermophysical properties, low pressure solubilities and thermodynamics of solvation of carbon dioxide and hydrogen in two ionic liquids based on the alkylsulfate anion

Densities and viscosities of the ionic liquid 1-butyl-3-methylimidazolium octylsulfate, [C4C1Im][C8SO4] were measured as a function of temperature between 313 K and 395 K. Solubilities of hydrogen and carbon dioxide were determined, between 283 K and 343 K, and at pressures close to atmospheric in [C4C1Im][C 8SO4] and in another ionic liquid based on the alkylsulfate anion-1-ethyl-3-methylimidazolium ethylsulfate, [C 2C1Im][C2SO4]. Density and viscosity were measured using a vibrating tube densimeter from Anton Paar and a rheometer from Rheometrics Scientific with accuracies of 10-3 g cm -3 and 1%, respectively. Solubilities were obtained using an isochoric saturation technique and, from the variation of solubility with temperature, the partial molar thermodynamic functions of solvation, such as the standard Gibbs energy, the enthalpy, and the entropy, are calculated. The precision of the experimental data, considered as the average absolute deviation of the Henry's law constants from appropriate smoothing equations, is better than ±1%. © The Royal Society of Chemistry.

Defending the Faith(s)?:Democracy and Hereditary Right in England

The persistence of traditional monarchies in modern societies, which are otherwise characterized by democratic and egalitarian values, remains a paradox in the social sciences. In part this is attributable to the lack of psychological investigation into the relationship between subject and sovereign, and in particular the ways in which the political and social values of the citizenry shape understandings of a hereditary monarch’s right to represent a national community. Adopting the qualitative analysis methods of discursive psychology and grounded theory, the current study examines vernacular accounts of nationhood and monarchy in England in both formalized conversational interviews (n = 60) and impromptu street interviews (n = 56). Focusing on accounts of Prince Charles’s recent proposal to change the role of the monarch, from “Defender of the (Christian) Faith” to “Defender of Faiths,” those in favor treated it as a positive step towards reflecting a diverse (religious) community, bringing the monarchy into line with current concerns of pluralism and upholding
values of personal choice and individual rights. Participants who rejected the proposed change in title construed it as antithetical to these values in terms of reflecting personal stake and interest, an abuse of power, or an imposition on other faiths. In all accounts, the prime concern was in safeguarding the political and social values of the citizenry. In conclusion it is argued that the study of subjects’ relationship to the monarch, its function and legitimacy, can provide an opportunity to examine how values can characterize a national community and facilitate national diversity.
