Matrix algebras with degenerate traces and trace identities

2022

In this paper we study matrix algebras with a degenerate trace in the framework of the theory of polynomial identities. The first part is devoted to the study of the algebra $D_n$ of $n \times n$ diagonal matrices. We prove that, in case of a degenerate trace, all its trace identities follow by the commutativity law and by pure trace identities. Moreover we relate the trace identities of $D_{n+1}$ endowed with a degenerate trace, to those of $D_n$ with the corresponding trace. This allows us to determine the generators of the trace T-ideal of $D_3$. In the second part we study commutative subalgebras of $M_k(F)$, denoted by $C_k$ of the type $F + J$ that can be endowed with the so-called st…

Trace Identities on Diagonal Matrix Algebras

2020

Let Dn be the algebra of n × n diagonal matrices. On such an algebra it is possible to define very many trace functions. The purpose of this paper is to present several results concerning trace identities satisfied by this kind of algebras.

La scoperta, sistemazione e conservazione della grande Iscrizione di Gortina, nell'isola di Creta (1884-1921): la protezione delle testimonianze e le…

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.

Tracking trace elements from soil to Lebanese bread and Populations Exposure

2021

In Lebanon, the agri-food industry represents 18% of the industrial sector and yet food safety remains a major problem. In this interdisciplinary thesis, we followed the Trace Elements (TEs) in the Lebanese white bread sector "from farm to fork" based on the reality on the ground, and on two links in the sector: (i) the geogenic or anthropogenic origin of TEs present in the soil and their transfer to the wheat grain, for which 10 plots cultivated in wheat, covering the diversity of soils, irrigation practices and anthropogenic environments of the central Bekaa were chosen ; (ii) the exposure of populations to TEs present in bread, for which a survey of consumption habits across Lebanon was …

Représenter et modéliser l'activité de recherche d'information experte avec des traces d'activité pour l'apprentissage

2010

Studies on the activity of information seeking and information literacy practices show that re-examining search behavior may improve search results. It is possible to strengthen this reflexivity by promoting the recovery and restoration of digital traces client-side, instead of just indexing them "server side". To understand the representations of information retrieval, we studied discourse of some students on their own information-seeking behavior and obtained models of their research.  In student accounts, subjective description of the concepts in question overshadowed any objective description of the activity.
