La catacomba di Villagrazia di Carini. Un documento della cristianizzazione di un insediamento rurale tardoantico
2008
Si ribadisce l'importanza storica e socio-economica del cimitero paleocristiano di Villagrazia (IV-VII sec.) quale documento di un esteso insediamento tardoantico connesso con la statio itinararia di Hyccara sulla via Valeria
Multi-omics of Pseudoalteromonas haloplanktis TAC125: a quest for antimicrobial metabolic pathways
Backgrounds The Antarctic strain Pseudoalteromonas haloplanktis TAC125 is one of the model organisms of cold-adapted bacteria and is currently exploited as a new alternative expression host for numerous biotechnological applications. Interestingly, this bacterium has been reported to be able to inhibit the growth of Burkholderia cepacia complex (Bcc) strains, opportunistic pathogens responsible for the infection of immune-compromised patients. Most likely, this occurs through the synthesis of several different compounds, including Volatile Organic Compounds (VOCs), whose nature and characteristics are currently mostly unknown. Objectives To obtain a complete picture of cellular processes di…
La diversité des communautés végétales des forêts alluviales de l’Allier est-elle affectée par l’invasion de l’Érable négundo, du Robinier faux-acaci…
2012
Identifiant ProdInra 270418 SPE EcolDur CT3; Master; L’objectif de notre étude a été d’analyser les effets de l’invasion de 3 espèces végétales (Érable négundo, Robinier faux-acacia, Renouée de Bohême) sur la diversité spécifique et fonctionnelle ainsi que sur la structure et la composition spécifique des communautés végétales des forêts alluviales de l’Allier. Des relevés de végétation ont été réalisés dans des paires de quadrats contiguës, envahis et non envahis par les 3 espèces invasives étudiées et dans 3 habitats envahis des forêts alluviales de l’Allier (Saulaie-peupleraie de niveau topographique haut et bas et Chênaie pédonculée-ormaie). Complémentairement à cette approche, un gradi…
Living Forms (of Art). Edoardo Kac's Transgenic Art between Ethics and Aesthetics
2013
Nel corso del Novecento si è assistito ad un intenso sviluppo della fisica e della biologia, grazie all’ausilio di nuovi strumenti tecnologici che hanno ampliato l’orizzonte della ricerca. Le sperimentazioni su organismi geneticamente modificati (come la famosa clonazione della pecora Dolly) hanno spesso generato scalpore, turbando le coscienze. Tali interventi sono tollerati in quei settori come la medicina in cui possono portare benefici all’esistenza dell’uomo, mentre suscitano inquietudine e perplessità in campo artistico dove l’intervento sulle forme viventi, non trovando giustificazione sul principio di utilità, sembra sfociare nel futile edonismo. Tenendo presente il dibattito avviat…
Creatività e arte transgenica
2012
Il brasiliano Edoardo Kac è stato tra i primi artisti biotecnologici ad applicare l’ingegneria genetica all’arte, dando avvio a quella che egli stesso nel 1998 ha definito Transgenic Art. Le sue creazioni di animali fluorescenti hanno turbato le coscienze e sono state spesso superficialmente reputate un’esibizione di mera spettacolarità al fine di emulare, non più solo a livello metaforico, il potere creativo di Dio. In realtà gli organismi fluorescenti che hanno conferito a Kac popolarità mediatica non s’iscrivono nella categoria della creatività volta a conferire nuovo prestigio all’artista-dio, secondo l’analogia imperante nel Rinascimento e nel Romanticismo, bensì in quell’estetica del …
Design and Implementation of Acoustic Source Localization on a Low-Cost IoT Edge Platform
2020
The implementation of algorithms for acoustic source localization on edge platforms for the Internet of Things (IoT) is gaining momentum. Applications based on acoustic monitoring can greatly benefit from efficient implementations of such algorithms, enabling novel services for smart homes and buildings or ambient-assisted living. In this context, this brief proposes extreme low-cost sound source localization system composed of two microphones and the low power microcontroller module ESP32. A Direction-Of-Arrival (DOA) algorithm has been implemented taking into account the specific features of this board, showing excellent performance despite the memory constraints imposed by the platform. …

Comercio de la Terra Sigillata Africana. Siglos I-VII d.n.e. [Mesa redonda "El comercio en el Mediterráneo antiguo: evolución, tendencias e interpret…
2021
En esta mesa redonda se debate en torno al fenómeno comercial en el Mediterráneo antiguo y sus vías de análisis. Para ello, se proponen cuatro casos de estudio que abarcan un amplio marco cronológico y cultural con el objetivo de mostrar el estado de la cuestión, las problemáticas y nuevas tendencias relativas a este campo de estudio. In this roundtable, the commercial phenomenon in the Ancient Mediterranean and its differentstudy approaches are discussed. To do that, four case studies covering a wide time and cultural frameare proposed, in order to show the state of the art, the problematics and new tendencies regarding this ield study.
Atmospheric pressure non-equilibriumplasma for the production of composite materials
2014
In the evolving field of tissue engineering, continuous advances are required to improve scaffold design and fabrication to obtain biomimetic supports for cell adhesion, proliferation, penetration and differentiation. Both electrospun fibrous scaffolds and hydrogels are used in this field since they well reproduce the structure of the extracellular matrix (ECM) of many biological tissues. Limitations of these two types of materials can be overcome through their combination, by developing composite structures combining enhanced mechanical properties (provided by the fibrous components) and improved cell penetration (provided by the gel phase) in a superior ability to mimic natural ECM that i…
Molecular characterization of Giardia duodenalis cysts in the Oreto river (Sicily, Southern Italy)
2012
<p><strong>Background</strong>: The presence of Giardia was investigated along the Oreto river between January 2008 and May 2009 with the aim of understanding the source of contamination by molecular typing of cysts.</p><p><strong>Methods</strong>: A total of 38 water samples (10 collected from the river mouth, 24 from the whole Oreto basin and 4 sewage samples from the Monreale treatment plant) were processed. In addition, 22 faecal samples of livestock living close to the Oreto area, were analyzed. The presence of Giardia was determined by immunofluorescence assay and their genetic characterization was achieved by a nested PCR assay targeting the …
