The role of seasonal tourism in fragile territories : the case of Solanas, Sardinia

Since the post-war period Italy has been invested by an epochal phenomenon of redistribution of population, economies and urban materials from highlands to lowlands, from the hinterland to the coastline. Moreover, since the 1970s, the development of the Mediterranean coastal territories assumed a character strongly oriented to tourism too, altering the balance sedimented through the years in these areas, converting many slow landscapes into intermittent territories triggered by specifc seasons and monocultural activities. This proposal intends to refect on the possible development weaving the destinies of such realities, in the awareness that the reactivation of these territorial systems could be led by the rediscovery of connections and emergencies often forgotten, silent traces able to give back values to these tired landscapes. Working through interconnected territorial structures means to consider their networks and their tangible and intangible capital, and this is an indispensable exercise in order to rethink our country and some of its reiterated development models. Starting with a few days of interdisciplinary seminars that took place in between Politecnico di Torino and Politecnico di Milano, and the organisation of a workshop on-site, Solanas was identifed as an emblematic case, a valley able to explore these issues. Located in the south of Sardinia, annexed to the territory of Sinnai due to its ancient transhumance role, today it remains detached from the main inhabited centres, suffering strong isolation from welfare systems during the low season, and the exploitation of landscape resources because of mere tourist purposes during the high season. This condition of seasonal contraction, unfortunately rarely accompanied by a medium-long term planning, can be retraced along many other coastal areas of Mediterranean countries, becoming a specifc fragility of our reality to take into consideration

Evaluation of Dental Surface after De-Bonding Orthodontic Bracket Bonded with a Novel Fluorescent Composite: In Vitro Comparative Study

The use of a new fluorescent composite can reduce some of the problems related to procedures of de-bonding orthodontic bracket (enamel damage, dentine lesions, and composite residuals). The aim of the presented study was to compare the effect of fluorescent and conventional non-fluorescent composite on dental surface and composite remnants by in vitro de-bonding tests. De-bonding of florescent composite (DFC) and the de-bonding of standard composite (DSC) were performed by operators on an in vitro sample of 48 teeth under UV light (360–370 nm min 20 mW/cm2). Modified ARI (Adhesive Remnant Index), scored under 5.0×/235 magnification, was used for evaluation of dental surface after the procedure, and the duration required for de-bonding was measured. Significant differences in ARI between the two groups were observed (Pearson two-tailed p = 0.006 1.4 ± 0.1 95% C.I.), and the average duration of de-bonding was 38 s (DFC) and 77 s (DSC) per tooth, respectively (Mann–Whitney test p = 0.015; 57.7 ± 19.9 95% C.I.). The use of fluorescent composite could significantly improve the quality of de-bonding by reducing the quantity of composite residuals and visible enamel damage, while reducing time needed for successful procedure performance

Autoxidation Products of the Methanolic Extract of the Leaves of Combretum micranthum Exert Antiviral Activity against Tomato Brown Rugose Fruit Virus (ToBRFV)

open7noTomato brown rugose fruit virus (ToBRFV) is a new damaging plant virus of great interest from both an economical and research point of view. ToBRFV is transmitted by contact, remains infective for months, and to-date, no resistant cultivars have been developed. Due to the relevance of this virus, new effective, sustainable, and operator-safe antiviral agents are needed. Thus, 4- hydroxybenzoic acid was identified as the main product of the alkaline autoxidation at high temperature of the methanolic extract of the leaves of C. micranthum, known for antiviral activity. The autoxidized extract and 4-hydroxybenzoic acid were assayed in in vitro experiments, in combination with a mechanical inoculation test of tomato plants. Catechinic acid, a common product of rearrangement of catechins in hot alkaline solution, was also tested. Degradation of the viral particles, evidenced by the absence of detectable ToBRFV RNA and the loss of virus infectivity, as a possible consequence of disassembly of the virus coat protein (CP), were shown. Homology modeling was then applied to prepare the protein model of ToBRFV CP, and its structure was optimized. Molecular docking simulation showed the interactions of the two compounds, with the amino acid residues responsible for CP-CP interactions. Catechinic acid showed the best binding energy value in comparison with ribavirin, an anti-tobamovirus agent.openValeria Iobbi, Anna Paola Lanteri, Andrea Minuto, Valentina Santoro, Giuseppe Ferrea, Paola Fossa, Angela BisioIobbi, Valeria; Paola Lanteri, Anna; Minuto, Andrea; Santoro, Valentina; Ferrea, Giuseppe; Fossa, Paola; Bisio, Angel

La construcción y de-construcción de la memoria : Deshaciendo los caminos del sentido común y las ideas hechas, a partir de una experiencia de extensión universitaria

El presente trabajo es el resultado de una experiencia grupal de extensión universitaria que realizamos durante el año 2006 en las ciudades bonaerenses de Miramar (partido de General Alvarado), Mar del Plata (partido de General Pueyrredón) y Santa Clara del Mar (partido de Mar Chiquita). Esta actividad formó parte de un proyecto colectivo más amplio: “Bicentenarios. Dos siglos de memoria colectiva” que venimos desarrollado desde entonces y que se enmarca en los festejos y conmemoraciones que se abrieron en 2006 y que se extenderán hasta el año 2016. Nuestro objetivo como grupo es des-andar los caminos de la “primera memoria”, aquella que construimos fundamentalmente a partir de una historia nacional monolítica, poco renovada, y que actualmente se está escuchando bajo una forma más “moderna” y “marketinera”, pero que no deja de presentar los procesos históricos de manera poco compleja y profundamente tradicional, utilizando el anacronismo como principal recurso. También, a través de nuestro proyecto, pretendemos fortalecer y retroalimentar los vínculos entre investigación, docencia y extensión, trabajando en diversos sentidos. A tal fin, y pensando en la inclusión de toda la comunidad local, hemos realizado algunas actividades de extensión tales como charlas, cine-debate, cursos temáticos y cuadernillos didácticos. Sobre esto último y como una colaboración con la práctica docente, trabajamos en la elaboración de dos cuadernillos de contenidos, fuentes y actividades sobre las invasiones inglesas, orientados a los 8º y 9º años de la EGB y al nivel Polimodal.Facultad de Humanidades y Ciencias de la Educació
