Low-temperature Ti-containing 3:2 and 2:1 mullite nanocrystals from single-phase gels
2007
Abstract TiO 2 -containig single-phase gels with (Al 2 O 3 + TiO 2 )/(SiO 2 ) molar ratios 3/2 and 2/1 were prepared by gelling mixtures of aluminium nitrate, tetraethylorthosilicate and titanium isopropoxide. Gels were fast heated at several temperatures up to 1100 °C. Dried and heated gels were characterized by differential thermal analysis (DTA), magic angle spinning nuclear magnetic resonance (MAS-NMR), X-ray powder diffraction (XRD), and scanning and transmission electron microscopies (SEM and TEM). Coupled DTA and XRD results of gels fast heated at 900 °C showed the crystallisation of two mullites as well as a small amount of alumina-silica spinel. 27 Al NMR spectra showed the format…
A Holonic Approach to Shakespeare: The Digital Reference System (DRS)
2012
Prefatory RemarksWhen hypertext was made available on the Internet after 1994 it shaped the concepts of public domain and free access. The web server and browsing system that Tim Berners-Lee and Robert Cailliau designed, determined the future digital, editorial and cultural developments for traditional audiences and digital natives alike. They quickly became the generalized interface tools and thus contributed to today's editorial standards. As they helped to create this innovative environment called the Internet, they also helped to establish many standards such as URL, URI, HTTP HTML or XML, which provided interoperability amongst different platforms and allowed internationalization.Shake…

An empirical evaluation of two natural hand interaction systems in augmented reality
2022
AbstractHuman-computer interaction based on hand gesture tracking is not uncommon in Augmented Reality. In fact, the most recent optical Augmented Reality devices include this type of natural interaction. However, due to hardware and system limitations, these devices, more often than not, settle for semi-natural interaction techniques, which may not always be appropriate for some of the tasks needed in Augmented Reality applications. For this reason, we compare two different optical Augmented Reality setups equipped with hand tracking. The first one is based on a Microsoft HoloLens (released in 2016) and the other one is based on a Magic Leap One (released more than two years later). Both d…
Are Distinctions Between Genres Still Relevant?
1998
Why do readers — and especially literary critics — feel the need to classify works of art into categories which one often calls genres? On the one hand fashionable ideas lead some commentators to argue that, in this infinitely innovative world, genres have become irrelevant because traditional rules have been subverted. The ineffable text (sacralized in italics) is all that counts. Yet, on the other, their description of works of literature inevitably resorts to such terms as ‘fantasy’, ‘allegory’, ‘realism’, ‘tragedy’, even if they carefully place these in inverted commas. As the ‘reception’ school of criticism has convincingly shown, a novel, poem or play takes on its full meaning when it…
Hybridization selects for prime‐numbered life cycles in Magicicada: An individual‐based simulation model of a structured periodical cicada population
2020
Abstract We investigate competition between separate periodical cicada populations each possessing different life‐cycle lengths. We build an individual‐based model to simulate the cicada life cycle and allow random migrations to occur between patches inhabited by the different populations. We show that if hybridization between different cycle lengths produces offspring that have an intermediate life‐cycle length, then predation acts disproportionately to select against the hybrid offspring. This happens because they emerge in low densities without the safety‐in‐numbers provided by either parent population. Thus, prime‐numbered life cycles that can better avoid hybridization are favored. How…
Zum Wandel translatorischer Normen. 1930 und 1953 als polnische Übersetzungskontexte von Thomas Manns "Der Zauberberg"
2018
The changes of translation norms. 1930 and 1953 as contexts of the translation of The Magic Mountain by Thomas Mann. The author presents the preliminary considerations related to a planned study the purpose of which is to reconstruct the history of the Polish translation of Der Zauberberg (The Magic Mountain) by Thomas Mann and examine its impact on the Polish reception of the work. Since each of the two parts of the novel were translated by different translators and because the second volume was translated twice (in 1930 and 1953), the translation contexts are very significant. The concept of context is presented in conjunction with the historically variable understanding of translation st…

A model for polybutadiene coatings on porous silica
1993
Non-wetting viscous liquids such as oligobutadiene prefer “active” sites such as pores during the process of physisorption. Thus, polybutadiene (PBD) coatings on porous silica do not result in a homogeneous polymer film but in an inhomogeneous loading where the bulk polymer is mainly sited in the pores of the silica. An increasing polymer loading leads to increasingly filled pores instead of a thicker polymer film. We cannot exclude the possibility that most of the surface is covered at least with a thin polymer film since the chromatographic behaviour is relatively good for polypeptides, which are highly susceptible to the silanol groups of silica.
Apparent magic numbers in embedded Ti-O clusters
2003
Stable clusters constituted of four ${\mathrm{TiO}}_{2}$ entities have been evidenced in nanometer-sized spinel oxides by a combination of diffraction and x-ray-absorption experiments. Contrary to free clusters, the size of the embedded clusters is strongly determined by the constraints imposed by the surrounding matrix so that the magic number of four is in fact specific to the matrix and only then apparent.
