THE KNOT SCRIPT – THE LOST WRITING SYSTEM OF THE LATVIAN LANGUAGE
2016
The article analyses a writing system of the Latvian language that has been scarcely researched before. The evidence of the usage of the knot script and song clews is present in the Latvian folklore, although it has been commonly considered as a metaphor. At the beginning of the 20th century there were individuals still using it prior to the conventional literacy increase due to the general education. Similar knot scripts can be found in several cultures around the globe. The article encompasses a study of previous researches and evidence in periodicals, Latvian community in Lithuania, education of commoners in Latvia, reciprocal comparison of the Latvian knot script writing systems, interv…
Epidemiology of invasive candidiasis in a surgical intensive care unit: an observational study
2015
Background: Invasive candidiasis (IC) is a frequent and life-threatening infection in critically ill patients. The aim of this study was to evaluate the epidemiology of IC and the antifungal susceptibility of etiological agents in patients admitted to our surgical intensive care unit (SICU) in Spain. Methods: We designed a prospective, observational, single center, population-based study in a SICU. We included all consecutive adult patients (≥18 years old) who had documented IC, either on admission or during their stay, between January 2012 and December 2013. Results: There were a total of 22 episodes of IC in the 1149 patients admitted during the 24-month study. The overall IC incidence wa…
L’inclusione vista dagli alunni: costruzione e validazione del questionario per rilevare la qualità inclusiva della scuola
2018
Molti studi nazionali e internazionali si sono concentrati sulla valutazione e sulla promozione della qualità inclusiva della scuola. Si tratta di un argomento complesso, che ha stimolato un ampio dibattito e una varietà di contributi che mettono in luce la necessità di uno strumento in grado di misurare la qualità inclusiva delle nostre scuole, per determinare l’evidenza empirica riguardo a questo tema. L’articolo presenta i risultati di una sperimentazione finalizzata alla redazione di un questionario per la rilevazione della qualità inclusiva del sistema scolastico percepita dagli alunni. Il questionario si pone come uno strumento di valutazione e autovalutazione che permette la misurazi…
Iron regulatory mechanisms in Saccharomyces cerevisiae
2020
Iron is an essential micronutrient for all eukaryotic organisms because it participates as a redox cofactor in many cellular processes. However, excess iron can damage cells since it promotes the generation of reactive oxygen species. The budding yeast Saccharomyces cerevisiae has been used as a model organism to study the adaptation of eukaryotic cells to changes in iron availability. Upon iron deficiency, yeast utilizes two transcription factors, Aft1 and Aft2, to activate the expression of a set of genes known as the iron regulon, which are implicated in iron uptake, recycling and mobilization. Moreover, Aft1 and Aft2 activate the expression of Cth2, an mRNA-binding protein that limits t…
Lack of Functional Trehalase Activity in Candida parapsilosis Increases Susceptibility to Itraconazole
2022
Central metabolic pathways may play a major role in the virulence of pathogenic fungi. Here, we have investigated the susceptibility of a Candida parapsilosis mutant deficient in trehalase activity (atc1Δ/ntc1Δ strain) to the azolic compounds Fluconazole and Itraconazole. A time-course exposure to Itraconazole but not Fluconazole induced a significant degree of cell-killing in mutant cells compared to the parental strain. Flow cytometry determinations indicated that Itraconazole was able to induce a marked production of endogenous ROS together with a simultaneous increase in membrane potential, these effects being irrelevant after Fluconazole addition. Furthermore, only …
Folk and Popular as "National": The Invention of the Italian Unity through Poetry and Music
2013
La nascita delle moderne filologia, musicologia ed etnologia nel XIX sec. ha contribuito ad approfondire anche in Italia lo studio scientifico della poesia e della musica non cólte. I termini popolare e nazionale, tuttavia, erano passibili all’epoca delle interpretazioni più varie, in virtù del diverso approccio delle tre discipline alla materia. Gli storici della letteratura si occupavano infatti di poesia con scarsa sensibilità per la musica, i musicologi di musica antica senza alcuna preparazione letteraria, gli etnologi indagavano i fenomeni nel loro accadere e solo in qualche caso formulavano ipotesi sulla storicità delle tradizioni. La prima generazione di studiosi delle tre branche p…
Yeast Life Span and its Impact on Food Fermentations
2019
Yeasts are very important microorganisms for food production. The high fermentative capacity, mainly of the species of the genus Saccharomyces, is a key factor for their biotechnological use, particularly to produce alcoholic beverages. As viability and vitality are essential to ensure their correct performance in industry, this review addresses the main aspects related to the cellular aging of these fungi as their senescence impacts their proper functioning. Laboratory strains of S. cerevisiae have proven a very successful model for elucidating the molecular mechanisms that control life span. Those mechanisms are shared by all eukaryotic cells. S. cerevisiae has two models of aging, replic…
Architecture and kinematics of forearc basins and intra-caldera resurgences: new insight from the Paola Basin (western offshore Calabria region) and …
This thesis deals with the patterns of tectonic deformation at different time and spatial scales ranging from tens to millions of years and from one to tens of kilometers, respectively. The study areas are the Campi Flegrei (Campania region, Italy) and Paola Basin (western offshore Calabria region, Italy). The Campi Flegrei and its offshore prolongation, the Pozzuoli Bay, are a laboratory for investigating volcano-tectonic deformations at 1yr-1kyr timescale and 1km spatial scale related to the dynamics of the Neapolitan Yellow Tuff (NYT) caldera and its intra-caldera resurgence. Resurgence is the late stage, long-term uplift of a collapse caldera floor to form a dome-like structure. The com…
Contatti culturali, identità e popolamento nel territorio imerese
2016
Il lavoro prende in considerazione il problema dei rapporti tra coloni greci e comunità indigene nel territorio di Himera, sulla base dei risultati della prospezione archeologica condotta per tre decenni nelle valli dei fiumi Imera settentrionale, Torto e S. Leonardo. Vengono esaminati gli elementi di cultura materiale che permettono di definire i modi dell'interazione culturale tra coloni e indigeni, nonché di ricostruire i paesaggi politici, socio-economici e il paesaggio del sacro nelle diverse aree indagate e nei diversi comprensori. La ricerca infatti permette di delineare, oltre alle usuali organizzazioni insediative e agricole della chora politiké e della éremos chora, anche articola…
Canzoni, ariette, gondole e barchette
2012
L'articolo tratta del genere della canzone in forma di barcarola,tra la metà del Settecento e il secondo Ottocento. Nella prima parte vengono evidenziati i tratti caratteristici del genere, a partire da una discussione della definizione data da Rousseau; e in seguito viene proposta una spiegazione del perché è utilizzato soprattutto il metro di 6/8. Nella seconda parte vengono analizzate due canzoni-barcarole particolarmente emblematiche: "La biondina in gondoleta", e "Santa Lucia".
