TiO2 nanocauruļu fotokatalītiskās aktivitātes kvantu ķīmijas pētījums
2015
Darba motivācija ir iegūt modeli, ar kura palīdzību var pētīt titāna dioksīda fotokatalītiskās un optiskās īpašības, jo TiO2 ir perspektīvs materiāls ūdens fotokatalītiskai sadalīšanai. Tā efektivitāti var palielināt, veidojot no tā nanocaurules — enerģētiski stabilas struktūras ar lielu virsmas laukumu un mainot TiO2 aizliegtās zonas platumu. Darbā ir aprakstīta TiO2 nanocauruļu periodisko modeļu reducēšana līdz neperiodiskiem modeļiem. Iegūtie modeļi, izmantojot uz blīvuma funkcionāla teorijas balstītus aprēķinus, tiek salīdzināti ar periodiskajiem modeļiem un tiek novērtēti faktori, kuri ietekmē modeļu elektronisko struktūru. Darba rezultātā ir piedāvāts skaitliskais eksperiments, ar kur…
Lévy-type diffusion on one-dimensional directed Cantor graphs.
2009
L\'evy-type walks with correlated jumps, induced by the topology of the medium, are studied on a class of one-dimensional deterministic graphs built from generalized Cantor and Smith-Volterra-Cantor sets. The particle performs a standard random walk on the sets but is also allowed to move ballistically throughout the empty regions. Using scaling relations and the mapping onto the electric network problem, we obtain the exact values of the scaling exponents for the asymptotic return probability, the resistivity and the mean square displacement as a function of the topological parameters of the sets. Interestingly, the systems undergoes a transition from superdiffusive to diffusive behavior a…
Bianca di Castiglia, regina madre di Francia
2017
Il saggio analizza la figura della regina Bianca di Castiglia, madre di Luigi IX di Francia, al di là degli stereotipi incrociando diverse tipologie di fonti e rileggendo la storiografia francese. Sono state individuate tre tematiche ritenute fondamentali per comprendere il ruolo giocato dalla regina: il rapporto con il figlio Luigi IX; le relazioni con i papi e l'imperatore Federico II; la fondazione di monasteri..

Kiedy sacrum sprofanowano, czyli sanktuarium św. Anny w czasie II wojny światowej
2016
The anastazy Piotr Polanko’s monograph “The Franciscans in annaberg during second World War” is anew publication concerning the history of the annaberg’s cloister just before the2ndWorld War and during the war. It has been published by st. antony’s Franciscan Publisher in 2013. It was elaborated on the basis of archives of annaberg’s Franciscan cloister. The author had to make an effort to translate the remaining documents from German. In his book he presents biographies of friars who lived in the cloister during first years of war, their ministry work with number of statistics regarding trips, sermons, retreats, pilgrimage movement, and then the moment of their exile from annaberg and gain…
From mental hygiene to mental health: ideology, discourses and practices in Franco’s Spain (1939–75)
2017
Based on an analysis of the discourses, the ideological appropriation and the practical influence of mental hygiene in Spanish psychiatry during the early years of the Francoist regime, this article examines its decline and subsequent replacement by the new concept of mental health promoted by the World Health Organization and other international bodies from the mid-twentieth century. The old approach, essentially focused on the prophylaxis of insanity within the framework of a set of interventionist policies of social defence, was thus transformed from the beginning of the 1960s into a much more ambitious and comprehensive project which sought to promote the psychosocial balance and perfo…
Fregi classici in miniatura: il Partenone e il tempio di Bassae di John Henning
2021
La Gipsoteca del Dipartimento Culture e Società dell’Università di Palermo, di recente riallestita, possiede tra i suoi calchi due gessi di grande interesse. Si tratta delle repliche delle versioni miniaturizzate dei fregi del Partenone e del Tempio di Bassae che lo scultore scozzese John Henning realizzò a Londra, nei primi decenni dell’Ottocento. Le riproduzioni furono inizialmente incise su piccole tavole di ardesia, dalle quali potevano essere ricavati calchi in gesso, destinati alla vendita. Ne nacque presto un lucroso commercio di copie non autorizzate, dal quale purtroppo Henning non guadagnò nulla. Tali manufatti, che poche volte hanno attirato l’attenzione degli archeologi, assolve…
