Akustische Masken auf dem Theater/ Maschere acustiche in teatro: Text - Sprache - Performanz/ Testo - Lingua - Performance
2019
I molteplici interessi scientifici e professionali - teatrologici, storici, linguistici, derivanti dall'attuale prassi attoriale e registica - che sono alla base di questi saggi offrono un quadro sfaccettato e complesso delle riflessioni sul discorso della comunicazione teatrale nei due paesi, le cui peculiarita, piu che le somiglianze, spiccando nel confronto, gettano una luce incrociata particolarmente interessante. Il filo rosso che si intreccia alla trama di questi contributi e senz'altro il complesso rapporto che lega la parola del testo teatrale con quella che si realizza sulla scena, ovverosia cio che in realta si puo definire lo specifico dell'evento teatrale in se, il quale si real…
Aldehyde dehydrogenase and HSP90 co-localize in human glioblastoma biopsy cells.
2013
The concept of a stem cell subpopulation as understood from normal epithelial tissue or bone marrow function has been extended to our understanding of cancer tissue and is now the target of treatment efforts specifically directed to this subpopulation. In glioblastoma, as well as in other cancers, increased expression of aldehyde dehydrogenase (ALDH) has been found localized within a minority sub-population of tumor cells which demonstrate stem cell properties. A separate body of research associated increased expression of heat-shock protein-90 (HSP90) with stem cell attributes. We present here results from our initial immunohistochemistry study of human glioblastoma biopsy tissue where bot…
Ohmic treatment of fresh foods: Effect on textural properties
2013
The aim of this work was to verify the effects of ohmic heating (OH) treatment on texture of fresh solid food (without pre-treatment in brine solutions), subjected to constant electrical field gradient (1100 V/m; 2200 V/m; 3300 V/m). Samples of fresh potatoes, carrots and apples cut into cylinders (d = 30 mm, h = 9.0 mm) underwent OH for 60, 120, 180 and 240 seconds. Texture measurements were performed in a universal testing machine Instron 4301, with a 100 N load cell, using a single-cycle compression test. The raw untreated sample was used as control. Stress–deformation behavior of food samples processed by OH differs appreciably from raw untreated samples for all cooking times. Firmness …
Catalytic cracking of n-alkane naphtha: The impact of olefin addition and active sites differentiation
2015
An extended dual kinetic model allows to fit the n-heptane cracking results working in a wide range of reaction conditions. The duality of the model is provided by the contribution of monomolecular and bimolecular cracking mechanisms. It takes into account the role played by the olefins formed on the global cracking or added within the feed. Furthermore by means of this model and the kinetic parameters obtained when cracking n-heptane on ZSM-5, it has been observed that, while some characterization techniques show a homogeneous zeolite surface from the point of view of the active sites, rigorous kinetic experiments point to the possibility that the reactant sees a heterogeneous surface with…
Non-celiac wheat sensitivity: differential diagnosis, triggers and implications.
2015
Abstract Non allergy-non-celiac wheat sensitivity (NCWS) has become a common and often overrated diagnosis. Skepticism mainly relates to patients with prominent intestinal symptoms in the absence of general or intestinal signs of inflammation. There is consensus that the major wheat sensitivities, celiac disease and wheat allergy, have to be ruled out which may be difficult for wheat allergy. The non-inflammatory intolerances to carbohydrates, mainly lactose and FODMAPs (fermentable oligi-, di-, monosaccharides and polyols), which cause bloating or diarrhoea, can usually be excluded clinically or by simple tests. Recent studies and experimental data strongly indicate that NCWS exists in a s…
Adopting magnetocaloric heat pumping and refrigeration for electrical vehicle
2017
International audience; Refrigeration process is based on conventional gas compression and expansion techniques. However, this technique has numerous disadvantages since it generates greenhouse gas and is partly responsible for global warming. This paper exposes analternative method: magnetocaloric refrigeration that presents the advantage to combine high-energy efficiency and respect of theenvironment. Magnetic heat pumping and cooling is compared to conventional method applied on vehicle air conditioning system.Simulation results are used to demonstrate the approach.
Nuove ricerche tuniso-italiane al teatro romano di Althiburos
2017
Il progetto di rilievo, scavo, studio e valorizzazione del teatro romano di Althiburos (El M’deïna, Tunisia) vede coinvolti l’Institut National du Patrimoine, l’Università di Macerata ed il Politecnico di Bari. Nelle tre campagne sinora svolte è stato iniziato il programma di rilievo del monumento e catalogo degli elementi architettonici e sono stati iniziati alcuni saggi stratigrafici che hanno permesso di indagare le fasi più tarde della vita dell’edificio, da quando cioè, in età bizantina, il teatro venne trasformato in fortezza sino all’età moderna. Il progetto della missione congiunta tuniso-italiana prevede di riprendere quest’anno lo studio del monumento e del materiale già scavato e…
Techniques de construction traditionnelles et techniques romaines dans le théâtre d’Althiburos et les monuments de spectacle de l’Afrique Proconsulai…
2023
The contribution aims to study the relationship between the traditional construction techniques of the territories of Proconsular Africa and those imported by the Romans and used in the construction of entertainment buildings, in particular theaters and amphitheatres, also taking into account the importation of typological models, starting from the “case study” of the theater of Althiburos. During the 1st and 2nd centuries AD there is a gradual introduction of Roman construction techniques, such as the opus caemaenticium, especially in the construction of substructures and vaults, sometimes with the importation of urban models, of techniques but also of Italic workers (just think of the opu…
"Saliamoci sopra e voliamo via..." Percorsi di Beni Montresor e Philip Glass verso "Le Streghe di Venezia" (1994-2009)
2016
Il saggio delinea i percorsi creativi di Philip Glass a partire dall'inizio dalla fine degli anni Sessanta, con particolare riferimento alle opere o spettacoli di teatro musicale. Nella seconda parte vengono descritti l'eperienza biografica e artistica di Beni Montresor, nonché la genesi e i caratteri musicali dell'opera in due atti "The Witches of Venice" (Le Streghe di Venezia, 1994-2009), presentata al Teatro Massimo di Palermo nella versione che include anche i testi di Vincenzo Cerami.
Stabilization of hsp70 mRNA on prolonged cell exposure to hypertonicity
2002
AbstractProlonged exposure of 3T3 cells to 0.5 osM hypertonic medium induced the accumulation of hsp70 mRNAs. This increase in mRNA levels required active protein synthesis. A weak and transient activation of heat shock factor 1 (HSF1) was noted, but it was temporally uncoupled to the accumulation of the hsp70 mRNAs. Nuclear run-on assay and transfection experiments showed that hsp70 gene transcription was not affected by hypertonicity. ActD chase experiments showed that during hypertonic treatment, degradation of hsp70 mRNAs was markedly reduced. This effect did not appear to be a general phenomenon since the increase in mRNA level of another gene induced by hypertonicity (ATA2 transporter…
