Effect of H Adsorption on the Magnetic Properties of an Fe Island on a W(110) Surface

2019

<p>Low-dimensional materials, such as ultrathin films, nanoislands and wires, are actively being researched due to their interesting magnetic properties and possible technological applications for example in high density data storage. Results of calculations of an Fe nanoisland on a W(110) support are presented here with particular focus on the effect of hydrogen adsorption on its magnetic properties. This is an important consideration since hydrogen is present even under ultra-high vacuum conditions. The calculations are based on density functional theory within the generalized gradient approximation. The adsorption of H atoms is found to strongly decrease the magnetic moment of the …

Programming languages and dynamic instructional tools: Addressing students’ knowledge base

1992

The chapter presents an instructional computer environment to be used in introductory Pascal programming classes. Traditional programming courses do not foster the kind of knowledge structures that are the trademark of expert programmers. These knowledge structures or programming templates provide programmers with a ready-to-use library of routines from which they draw when writing a new program. Developed as a hypertext tool, TAP (Template Assisted Programming) is an instructional environment to teach programming that emphasizes the development and use of such a library of routines by presenting students with a multiple representation of programming knowledge. In TAP students can (a) switc…

Pipistrellus kuhlii (Kuhl, 1817) (Mammalia: Chiroptera): a species new to the fauna of Tajikistan

2022

Pipistrellus kuhlii (Kuhl, 1817) (Mammalia: Chiroptera): a species new to the fauna of Tajikistan. In the paper, the first record of Pipistrellus kuhlii (Kuhl, 1817) in Tajikistan is described. The site is located approximately 500 km from the northern sites of this species in Afghanistan. The discussed issues are connected with the possible isolation of the Central-Eastern Asian populations of this species. The article includes a discussion on assigning the population of P. kuhlii from Eastern Europe to a subspecies and suggests the need for further research that would allow for a clear taxonomic assignment of the analysed population.

La stereotomia nella cattedra di Architettura statica di Carlo Giachery

2014

La scuola di architettura di Palermo, sin dalla sua fondazione nel 1779, con la creazione della cattedra di Architettura civile affidata a Giuseppe Venanzio Marvuglia, era divenuta inevitabilmente il luogo di verifica e talvolta di esplorazione dei temi legati alla pratica professionale e, quindi, all’arte del costruire. Giachery, Professore di Architettura statica e civile dal 1837 al 1865, è il primo ad avvertire, da docente, la crisi profonda del sistema didattico della scuola di architettura di Palermo isterilita dalla ricerca di astratte idealità neoclassiche e straniatasi dal processo evolutivo della cultura architettonica europea dopo la morte dei “maestri” Marviglia e Gentile. Secon…

The School of Architecture of Palermo since its founding in 1779 with the creation of the chair of Civil Architecture entrusted to Joseph Venantius Marvuglia has become the place of testing exploration of issues related to professional practice and the art of building. Carlo Giachery Professor of Static and Civil Architecture from 1837 to 1865 is the first to feel the deep crisis of the educational system of the school of architecture of Palermo. For him architecture and applied sciences to architecture found in their stereotomy confirmation of the existence of correspondent relationships in their evolutionary process. The notion of stereotomy taken by Carlo Giachery in teaching reconnects directly to the noble art of coupe des pierres. Taken together the teaching aids used to show a theoretical advance that Giachery inclined in the direction of elasticity of the materials. Noting the outcomes of teaching his students have the clear perception of how the teaching on stereotomy is the compendium of all the French tradition on the subject. With the establishment of the School of Application for Engineers and Architects in 1866 the steretomia seems to gradually lose interest in favor of the prevailing metal construction. All the wisdom of build which for centuries had been linked with art de la coupe des pierres gave way to new construction techniques and new materials.Settore ICAR/14 - Composizione Architettonica E Urbana

Ultreya, suseya, Santiago!” Viaggio e spazialità ne La ballata dei pellegrini

2020

Per studiare dal punto di vista della geografia culturale alcuni aspetti del pellegrinaggio a Santiago de Compostela, in Spagna, il capitolo prende in considerazione un testo letterario, il romanzo autobiografico "La ballata dei pellegrini" della scrittrice francese Edith De La Héronnière, pubblicato per la prima volta nel 1993 e tradotto in italiano nel 2004. Il romanzo racconta l’esperienza del pellegrinaggio giacobeo effettuato dall’autrice negli anni Novanta assieme a tre compagni di viaggio partendo da un cammino francese. In particolare, attraverso l’analisi di alcune parti del testo, si indagano le modalità attraverso le quali la narrazione costruisce e descrive lo spazio fisico e si…

The contribution critically and from a geographical perspective discusses the connection between propaganda comics and cartoons in the period of twentieth-century totalitarianisms. The way in which space real and symbolic is implicated through the rhetoric and dialectics of power in social economic and identity dynamics is then explored. In order to study some aspects of the pilgrimage to Santiago de Compostela from the point of view of cultural geography in Spain the chapter takes into consideration a literary text the autobiographical novel "The pilgrims' ballad" by the French writer Edith De La Héronnière first published in 1993 and translated into Italian in 2004. The novel recounts the experience of the Jacobean pilgrimage carried out by the author in the nineties together with three traveling companions starting from a French journey. In particular through the analysis of some parts of the text the ways in which the narration constructs and describes the physical and symbolic space of the pilgrimage are investigated. In this way it is possible to explore the way in which peculiar attributions of meaning inscribe the experience of pilgrimage in a symbolic universe that is both personal and collective at the same time.

2013

La scoperta e la conservazione della Grande Iscrizione di Gortina a Creta, da parte degli studiosi italiani, fra la fine del XIX sec. e i primi decenni del XX sec., rappresentò un grande riconoscimento scientifico-culturale per la giovane nazione italiana. Nel passato, l’isola di Creta era stata legata alla Repubblica di Venezia e anche questo rapporto favorì l’invio a Creta del giovane epigrafista F. Halbherr, il quale fra notevoli peripezie rinvenne, assieme all’epigrafista tedesco E. Fabricius, la famosa l’iscrizione nell’antica città di Gortina. L’iscrizione, fra le più antiche e complete finora conosciute in tutta Europa, conteneva le norme sulla famiglia, l’eredità e in generale i dir…

The discovery and preservation of the Great Inscription of Gortyna in Crete by Italian researchers in the late nineteenth century. and the first decades of the twentieth century. was an important cultural and scientific recognition for the young Italian nation. In the past the island of Crete had been tied to the Republic of Venice and this report also favored sending in Crete the young epigraphist F. Halbherr who among considerable vicissitudes came to together to the epigraphist german E. Fabricius the inclusion of the famous ancient city of Gortyna. The inscription among the oldest and most comprehensive so far known throughout Europe the rules contained on the family's legacy in general and the rights and duties of some of the people of the Minoan civilization (480-450 BC). The inscription was carved on blocks organic limestone a restored ancient building which later in Roman times was turned into odeon. The Laws of Gortyn were engraved on the remains of the wall forming the passageway in front of the steps of the odeon. The essay traces the events that led to the discovery and subsequent storage made by Halbherr especially with the help of archaeologist L. Pernier and finally with the help of architect E. Stefani who designed a modern cover on the top of the ambulatory of the segments containing the inscription. This coverage was made to perform during the First World War on the basis of the Italian project from the Greek Government in order to protect the membership from possible war damage but especially from vandalism. The roof brick clay of the Laws of Gortyna still serves its function and ensures the use of the monument bearing witness to the preservation of Italian culture in Greece and more generally in the world. But in Sicily in the remains of the Villa del Casale in Piazza Armerina (Enna) its elegant protection (built in 1957) is representative of a whole period of culture of the Italian restoration is removed and replaced because it has not been able to make a ongoing maintenance is due. A bad example of conservation and management of a UNESCO monument from which arise after the work for the construction of new roofs an equally insulting to the archaeological heritage and scenic Italian and world.Settore ICAR/19 - Restauro

Traducción y recepción: Rosalía de Castro en Italia

2020

El panorama de la recepción italiana contemporánea de los poetas españoles del siglo XIX, a través de las traducciones, no resulta especialmente satisfactorio, puesto que hay que esperar el siglo siguiente para encontrar los primeros estudios monográficos y ediciones de textos en traducción, aunque en forma antológica. Ello, no obstante, así como en el resto de Europa, el corpus de las publicaciones periódicas de las revistas ofrece un canal editorial muy proficuo para la recepción de textos literarios extranjeros. Este trabajo se centra en la presencia de la obra de Rosalía de Castro en la prensa italiana contemporánea. Al mismo tiempo, se ha intentado completar el estudio de la recepción …

The panorama of the contemporary Italian reception of the Spanish poets of the 19th century through translations is not particularly satisfactory since it is necessary to wait for the following century to find the first monographic studies and editions of texts in translation although in anthological form. However as in the rest of Europe the corpus of periodicals of magazines offers a very profitable editorial channel for receiving foreign literary texts. This work focuses on the presence of Rosalía de Castro's work in the contemporary Italian press. At the same time attempts have been made to complete the study of the reception of the Galician poet in Italy collecting traces in other editorial products such as the book. The consequent analytical focus will correspond to the transnational study of some proto and meta texts individualized by their special interest.

L'intonaco Li Vigni nell'architettura del XX secolo a Palermo. Nuove conoscenze e applicazioni diagnostiche per la manutenzione

2013

Il saggio presenta lo studio degli intonaci formulati per imitare le pietre e i marmi naturali che si diffondono in Sicilia all’inizio del XX secolo ed evidenzia che le prime applicazioni e la diffusione delle nuove malte, anche nel resto dell’Italia, risentono delle sperimentazioni condotte in tutta l’Europa. Il contributo riassume i risultati di una rigorosa e capillare ricognizione tra i brevetti conservati presso l’Archivio Centrale dello Stato a Roma inerenti alle malte per il confezionamento dell’intonaco a “finta pietra”, ne analizza i contenuti in modo critico e pone in risalto i contatti culturali con le sperimentazioni dei materiali in atto nell’ambito dei grandi cantieri di resta…

The paper presents the study of the plaster formulated to imitate the natural stones and marbles that are popular in Sicily in the early twentieth century and points out that the first applications and the dissemination of new mortars also in the rest of Italy feels the influence of the experiments conducted throughout Europe . The contribution summarizes the results of a rigorous and thorough reconnaissance of patents kept in the Archivio Centrale dello Stato in Rome relating to mortars for plastering an artificial stone critically analyzes the content and emphasizes cultural contacts with the experiments on large-scale restoration projects in Italy and France in the late nineteenth century. The analysis of the architectural surfaces is developed with instrumental tests: the levels of adhesion of finishing surface are characterized in particular through a campaign of thermographic investigations and diagnosis is drawn to show that the consolidation of the layers and reintegration are interventions to be introduced ​​within the restoration project and maintenance program.Settore ICAR/19 - Restauro
