First Report of Tomato torrado virus Infecting Tomato in Italy.
2010
In 2009 and 2010, approximately 2% of plants had disease symptoms, including initial leaflet chlorosis that later developed into necrotic spots and general necroses along the leaflet. Fruit production on affected plants was substantially reduced and necroses were also present. Total RNA was extracted from five symptomatic plant samples using the RNeasy Plant Mini Kit (Qiagen, Hilden, Germany) and analyzed by reverse transcription (RT)-PCR with specific primer pair: TR2F (5′ GAAGGACGAAGAGCGACTG 3′), and TR2R (5′ AAGGTAGGTATGCGTTTGC 3′) (1). The primers amplified a 575-bp fragment within the coat protein Vp23 of Tomato torrado virus (ToTV). No RT-PCR products were observed when water or asym…
Vescovo e cattedrale a Cirene nel VI secolo: a proposito della basilica orientale

3D mosaic documentation using close range photogrammetry
2015
The paper describes the close range photogrammetric survey of a roman mosaic stored at Regional Archaeological Museum “Antonino Salinas” in Palermo (Italy). The aim of the work is the production of a full-scale representation (scale 1:1) of the mosaic useful for documentation and restoration processes. The research has allowed evaluating limit and potentiality of image-based approach using photogrammetric and computer vision (Structure for Motion) techniques in a context where the metric point of view is a very important factor.
Fast Image Mosaicing for Panoramic Face Recognition
2006
In this article, we present some development results of a system that performs mosaicing (or mosaicking) of panoramic faces. Our objective is to study the feasibility of panoramic face construction in real-time. To do so, we built a simple acquisition system composed of 5 standard cameras which, together, can take simultaneously 5 views of a face at different angles. Then, we chose an easily hardware-achievable algorithm, consisting of successive linear transformations, in order to compose a panoramic face from these 5 views. The method has been tested on a relatively large number of faces. In order to validate our system of panoramic face mosaicing, we also conducted a preliminary study on…
Restauro di una Chiesa Bizantina a En-Nitl in Giordana.
2009
L'articolo descrive il progetto di restauro di due piccole Chiese. Dopo aver individuato la successione temporale delle strutture murarie, l’esame si è concentrato sul mosaico rinvenuto nella Chiesa principale, dedicata a San Sergio. Il progetto è suddiviso in tre fasi: la prima fase riguarda l’intervento di conservazione del mosaico pavimentale; la seconda fase prende in esame la copertura della Chiesa, con una tenda di quelle utilizzate dei beduini del deserto; la terza fase è dedicata al cantiere di restauro.
Rewriting antiquity, renewing Rome. The Identity of the Eternal City through Visual Art, Monumental Inscriptions and the Mirabilia
2011
AbstractDuring the eleventh and twelfth centuries the Church began a process of renovation (renovatio) and the city of Rome was given new meanings. Antiquity is part of the identity of the Eternal City; the reuse or reframing of aspects of antiquity inevitably transformed the image of Rome. Public spaces, architecture and objects were given new Christian readings. Inscriptions, present both in sacred and secular settings, played an important role. A similar rewriting can also be found in travel literature and descriptions of the city, such as in the Mirabilia urbis Rome, where ancient monuments were re-interpreted to demonstrate the superiority of Christianity. Inscriptions were used as sym…
Le Domus di Piazza della Vittoria a Palermo
2012
Urban archaelogy is an important source of information in order to learn about the history and the culture of a town. The city of Palermo is a great example of a highly stratified area which is characterized by a complex urban and architectonic palimpsest. Promoting the knowledge, the conservation and the enhancement of its historical and archaeological urban sites is, therefore, central to rebuild the diachronic and diatopic dimension of the past, through the use of cognitive means and technical competences. This is the author's aim of the study.
From the Golgi-Cajal mapping to the transmitter-based characterization of the neuronal networks leading to two modes of brain communication: Wiring a…
2007
After Golgi-Cajal mapped neural circuits, the discovery and mapping of the central monoamine neurons opened up for a new understanding of interneuronal communication by indicating that another form of communication exists. For instance, it was found that dopamine may be released as a prolactin inhibitory factor from the median eminence, indicating an alternative mode of dopamine communication in the brain. Subsequently, the analysis of the locus coeruleus noradrenaline neurons demonstrated a novel type of lower brainstem neuron that monosynaptically and globally innervated the entire CNS. Furthermore, the ascending raphe serotonin neuron systems were found to globally innervate the forebrai…
Desarrollo de productos avanzados para la misión SEOSAT/Ingenio
2016
SEOSAT/Ingenio es la futura misión española de observación de la Tierra en el óptico en alta resolución espacial. Mientras que los productos de imagen a Nivel 1, radiancias geo-referenciadas a nivel de sensor, se encuentran en una fase avanzada de desarrollo existiendo para ello un contrato industrial, los productos de Nivel 2 deben ser desarrollados por los propios usuarios. Este hecho limita el uso de las imágenes a la comunidad científica, restringiendo sus posibles aplicaciones fuera de ésta. Así pues, bajo el marco de un proyecto coordinado y motivados por ofrecer productos de Ingenio/SEOSAT de Nivel 2 a disposición de cualquier usuario, se origina y desarrolla este trabajo. En este ar…
Arabidopsis thalianagenes contributing to differences in the outcome of infection with generalist and specialist strains ofTurnip mosaic virusidentif…
2020
AbstractPathogens can be classified as generalists or specialists depending on their host breadth. While generalists are able to successfully infect a wide variety of host species, the host range of specialists is limited to a few related species. Even though generalists seem to gain an advantage due to their wide host range, they usually pay a cost in terms of fitness within each host species (i.e., the jack-of-all trades, master of none). On the contrary, specialists have high fitness within their own host. A highly relevant yet poorly explored question is whether generalist and specialist viruses differ in the way they interact with their host’s gene expression networks. To identify host…
