Allo-repetition in Academic Settings. Cooperation, Understanding Co-construction and Knowledge Negotiation in the Medical Section of the ELFA Corpus
2015
In recent years, spoken academic ELF (English as a Lingua Franca) has been an object of in- creasing interest in linguistic and communication studies thanks to the position of academia as “one of the domains which have most eagerly adopted English as their common language in in- ternational communication” (Mauranen 2006a: 146) 1. In a context where different linguistic and cultural backgrounds come together, clarity and explicitness play a prominent role. In this respect, ELF research has paid much attention to the importance of communicative strategies, the most prominent of which is repetition. ELF studies on repetition have been carried out in several do- mains, including academia. Withi…
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…
From C–S–H to C–A–S–H: Experimental study and thermodynamic modelling
2015
Abstract It has long been known that the stoichiometry of C–S–H varies with the calcium hydroxide concentration in solution. However, this issue is still far from understood. We revisit it in both experimental and modelling aspects. A careful analysis of the solubility confirms the existence of three different C–S–H phases, defined as Ca 4 H 4 Si 5 O 16 , Ca 2 H 2 Si 2 O 7 and Ca 6 (HSi 2 O 7 ) 2 (OH) 2 , respectively. The variation of the Ca/Si ratio of the three phases has been described by surface reactions: the increase of the Si content is accounted for by silicate bridging, the increase of calcium content and the surface charge are accounted for by reactions involving silanol groups v…
Shear coefficient determination in linear friction welding of aluminum alloys
2015
In the present study, a combined experimental and numerical investigation on Linear Friction Welding (LFW) of AA2011-T3 aluminum alloy was carried out in order to find the temperature dependent shear coefficient to be used in a 3D numerical model of the process. Torque, oscillation frequency and pressure were acquired in order to calculate the shear stress at the interface. A numerical thermal model was used to calculate the temperature at the interface between the specimens starting from experimental temperatures acquired through a thermocouple embedded in the LFW specimens. Finally, the calculated shear coefficient was used to model the contact between the two specimens in a dedicated 3D,…
Jóvenes migrantes al habla: trayectorias educativas y vidas con género
2018
El artículo muestra la tensión biográfica y el proceso educativo de dos jóvenes menores que viajaron de África a Europa a través de construcciones biográficas marcadas por el paso de sociedad de origen a sociedad de destino. El relato y la representación gráfica de la trayectoria vivida aportan elementos de reflexión sobre el encauzamiento del alumnado de incorporación tardía en nuestra sociedad. Ambas biografías se extraen de una investigación que tiene por objeto conocer qué hace posible la progresión educativa exitosa del alumnado de incorporación tardía que vive en contextos vulnerables. A través de trayectorias encauzadas por el género y una clase social de origen media, Badra y Dakar …
Mandibular ameloblastoma : reconstruction with iliac crest graft and implants
2007
The ameloblastoma is a bening odontogenic tumor. The treatment planning in young persons is still not clear. We describe a case report of a young boy who was treated in our unit and we review the different aproaches for this type of lesions, which nowadays still not clear in this patients.
A procedure to calculate the I–V characteristics of thin-film photovoltaic modules using an explicit rational form
2015
Abstract Accurate models of the electrical behaviour of photovoltaic modules are effective tools for system design. One or two diode equivalent circuits have been widely used even though some mathematical difficulties were found dealing with implicit equations. In this paper, a new model based on a simple rational function, which does not contain any implicit exponential form, is presented. The model was conceived in order to be used with thin-film photovoltaic modules, whose current–voltage curves are characterised by very smooth shapes. The parameters of the model are evaluated by means of the derivatives of the issued characteristics in the short circuit and open circuit points at standa…
Much more than a clasp : evolutionary patterns of amplexus diversity in anurans
2020
The evolution and diversification of animal reproductive modes have been pivotal questions in behavioural ecology. Amphibians present the highest diversity of reproductive modes among vertebrates, involving various behavioural, physiological and morphological traits. One such feature is the amplexus, which is the clasp or embrace of males on females during reproduction and is found almost universally in anurans. Hypotheses about the origin of amplexus are limited and have not been tested thoroughly, nor have they taken into account evolutionary relationships in most comparative studies. However, these considerations are crucial to an understanding of the evolution of reproductive modes. Her…
Restoration of the Zisa Palace, Palermo
1993
The building of the Zisa, commissioned by William I, began in 1164-1165; it was completed by William II in the years immediately following. It was built as a splendid place for rest and amusement, ...
TERME
2023
This contribution in terminology aims at taking into consideration the semantic and functional constituents of terms in a cognitive and discursive perspective. To this end, Geeraerts’ model of cognitive lexicology is used to study and exemplify the dimensions of linguistic signs. This discussion opens the door to a modern understanding of linguistic meaning that is provided for a holistic approach by frames, constructions and patterns. The observation of in-context-meaning in terminology is necessary in the broader perspective of a specialized discourse analysis based on the qualitative and quantitative investigation of authentic language material from documented interpersonal communication…
