Ion beam shaping and downsizing of nanostructures
2011
We report a new approach for progressive and well-controlled downsizing of nanostructures below the 10 nm scale. Low energetic ion beam (Ar+) is used for gentle surface erosion, progressively shrinking the dimensions with ~ 1 nm accuracy. The method enables shaping of nanostructure geometry and polishing the surface. The process is clean room / high vacuum compatible being suitable for various applications. Apart from technological advantages, the method enables study of various size phenomena on the same sample between sessions of ion beam treatment.
Close packing of clusters: Application toAl100
2003
The lowest energy configurations of close-packed clusters up to N=110 atoms with stacking faults are studied using the Monte Carlo method with Metropolis algorithm. Two types of contact interactions, a pair-potential and a many-atom interaction, are used. Enhanced stability is shown for N=12, 26, 38, 50, 59, 61, 68, 75, 79, 86, 100 and 102, of which only the sizes 38, 75, 79, 86, and 102 are pure FCC clusters, the others having stacking faults. A connection between the model potential and density functional calculations is studied in the case of Al_100. The density functional calculations are consistent with the experimental fact that there exist epitaxially grown FCC clusters starting from…
Monte Carlo simulation of correlated electrons in disordered systems
1992
Abstract The properties of many-electron states in disordered systems with long-range electron-eletron interaction are investigated by means of a Monte Carlo simulation. Using the Metropolis algorithm, three-dimensional systems up to 512 sites are systematically analysed. The low-lying excitations are investigated in order to distinguish between one-particle and many-particle hopping. In the interesting regime in which disorder and correlation effects are equally important we find that variable-range hopping is insignificant for electron transfer when compared with the contribution from nearest-neighbour one-electron hopping processes as well as variable-number hopping.
Monte Carlo simulation of crystalline polyethylene
1996
Abstract We consider here the problem of constructing an efficient algorithm for a classical Monte Carlo simulation of crystalline polyethylene with unconstrained bond lengths and angles. This macromolecular crystal presents a particular example of a system with many different energy scales, ranging from soft ones represented by nonbonded van der Waals interactions, to stiff ones, represented in particular by bond stretching. A proper sampling of all the energy scales poses a problem and it is shown that a standard Metropolis algorithm employing just local moves is not very efficient at low temperatures. As a solution it is proposed to employ also global moves consisting of displacements of…
Flavonoids of honey and propolis : characterization and effects on hepatic drug-metabolizing enzymes and benzo(a)pyrene-DNA binding in rats
1996
The influence of dietary sunflower honey, propolis, and a flavonoid extract of propolis was examined on drug-metabolizing enzyme activities in rat liver and on microsome-mediated binding of benzo[a]pyrene to DNA. Characterization of flavonoids present in sunflower honey and propolis was achieved in order to assess the relative effects of different components of honey and propolis. Honey and propolis contained the same major flavonoids, pinocembrin, chrysin, galangin, and pinobanksin. The concentration of flavonoids was higher in propolis. Sunflower honey produced no significant changes on phase I and phase II enzyme activities and no modification of in vitro binding of benzo[a]pyrene to DNA…
Early modern state formation in the margins? A review of early modern popular politics and limited royal power in the Polish-Lithuanian Commonwealth …
2017
The traditional historiography of early modern state-building has usually followed the western European paradigm of historiography, the usual models being France, England, Brandenburg-Prussia and Sweden. Regions that do not follow this paradigm have simply been left out and labeled “backward” or as “lagging behind”. In this literary review, our focus is on two different and rather surprising cases of early modern state formation: the Polish-Lithuanian Commonwealth and the Spanish colonial empire in Latin America. By following the scholarship on these two large conglomerates, we focus on two scholarly concepts: the idea of early modern realms as composite/conglomerate states, and state forma…
Obraz wspólnoty katolickiej w polskim dyskursie religijnym
2018
The aim of the article is to analyse contemporary patriotic preaching. It proves that the ethnocentrism of the Church in Poland, has an ethnically based definition of sacrum, limiting one's view to the Polish national community. As a consequence 'we'in such discourse is an equivalent of 'we, the Polish people'. Christian (or generally: human, universal) attitude is not evident. In the first part of the article the main elements of religious discourse are presented: type of speaker (hierarchs of the Church - archbishops, bishops), occasions (national and religious celebrations), places (cathedral, basilica, Jasna Góra Monastery). In the second part of the article, its author analyses a sermo…
Towards a genealogy of the gender space of politics.
2017
El artículo pretende trazar, en la edad clásica de nuestra civilización occidental, el esquema lógico binario del que sobresale la división de género del espacio político. Esta se fundamenta en la tensión excluyente que encierra la polis y el oikos en dos distintas dimensiones, caracterizadas por una discordancia constitutiva de la ciudadanía y de la subordinación femenina. Finalmente se evocan brevemente dos líneas de fuga representadas por las figuras corpóreas de Penélope y de Antígona. The aim of this article is to trace a logical, binary outline of the classical period of western civilisation, from which the gender division of political space has emerged. This gender division has been …
CHE SENSO HA? POLISEMIA E ATTIVITA' DI LINGUAGGIO
2012
I fenomeni di polisemia lessicale costituiscono un ingrediente essenziale dell'attività umana di linguaggio. Semiotici, linguisti e studiosi di scienze cognitive esaminano questi fenomeni da prospettive differenti. I saggi raccolti in questo volume provano a tener conto di alcuni importanti risultati derivanti dall'analisi di tali prospettive. L'immagine complessiva che emerge è di straordinaria ricchezza e di grande impatto. Non vi è aspetto dell'attività umana di linguaggio che non possa essere in qualche modo ripensato a a partire dai fenomeni di polisemia lessicale. Il libro, attraverso un confronto sistematico delle principali strategie impiegate nello studio di tali fenomeni prova ad …

2014
Nel sistema semantico della lingua latina i processi di significazione sono organizzati dall'autore secondo modelli di profondità nei quali gli elementi di tipo logico-semantico si convertono in piani semantico-sintattici per poi passare alla semiosi in cui ogni parola ha una precisa funzione di segno e di significazione di idee.
