Una proiezione spaziale per la musica del nostro tempo
2020
Articolo su una proposta progettuale che, svolta come Tesi di Laurea da Sara Sgueglia (relatore Renato Capozzi e Correlatrice Claudia Sansò), prevede per le tre parti del complesso di Nebida - Il Polo, l’ex laveria La Carroccia e l’Approdo - non solo un cambiamento funzionale, ma una mutazione di senso. Ciò trasforma la preesistenza, un esempio di archeologia industriale ubicata nel lato Ovest della Sardegna, in un luogo per acquisire nuove tecniche di registrazione sonora. Progetto vincitore del premio Camerino 2019. Article on a project proposal that, carried out as a thesis by Sara Sgueglia (rapporteur Renato Capozzi and co-rapporteur Claudia Sansò), foresees for the three parts of the N…
Trastornos obsesivo-compulsivo: creencias, conocimientos y estigma en el ámbito docente
2014
El trastorno obsesivo-compulsivo (TOC) está catalogado como un trastorno caracterizado por dos síntomas que otorgan el nombre de la patología; las obsesiones y las compulsiones. A pesar de la existencia de tratamientos eficaces, en muchas ocasiones, el trastorno no se reconoce, y en consecuencia, no se trata. La falta de conocimiento (por ejemplo, pobre alfabetización en salud mental (Mental Health Literacy)) sobre el trastorno obsesivo-compulsivo en el ámbito docente puede ser un impedimento para la búsqueda de ayuda profesional y tratamientos, y la consecuente cronificación del trastorno. Objetivos: El presente estudio intenta evaluar el conocimiento, las creencias y el estigma asociado a…

A Band Model of Cambium Development: Opportunities and Prospects
2021
More than 60% of tree phytomass is concentrated in stem wood, which is the result of periodic activity of the cambium. Nevertheless, there are few attempts to quantitatively describe cambium dynamics. In this study, we develop a state-of-the-art band model of cambium development, based on the kinetic heterogeneity of the cambial zone and the connectivity of the cell structure. The model describes seasonal cambium development based on an exponential function under climate forcing which can be effectively used to estimate the seasonal cell production for individual trees. It was shown that the model is able to simulate different cell production for fast-, middle- and slow-growing trees under …
Wood formation in pedunculate oak and its relation with climatic factors in Latvia
2013
Šajā darbā ir analizēta parastā ozola (Quercus robur L.) augšanas saistība ar klimatiskajiem faktoriem Latvijā (43 vietas), izmantojot dendrohronoloăijas un dendroekoloģijas metodes. Klimata ietekmes novērtējumam, izmantoja divus atšķirīgus gadskārtu mērījumus: gadskārtu platumu un pavasara koksnes traheju dobumu laukumu. Ozola augšana uzrādīja atšķirības gar austrumu-rietumu gradientu saistībā ar klimata kontinentalitāti. Balstoties uz šo gradientu Latvijas teritoriju var iedalīt divās daļās (rietumu un austrumu reģionā). Gadskārtu platumu rietumu reģionā, galvenokārt, ietekmēja pavasara un vasaras gaisa temperatūra, bet austrumu reģionā klimatisko faktoru, kas ir saistīti ar sausumu vasar…
Monitoring Volcanic Eruptions Using Trace Metals In Tree-Rings: Preliminary Results From Mt. Etna
2010
8. Active volcanoes can influence surrounding vegetation both through passive degassing during quiescent periods and through eruptive degassing, by introducing into the atmosphere several metals as gases and particles. The chemical composition of tree-rings has been generally used to investigate the effects of anthropogenic gas emissions and dendrochemical methods have successfully recorded variations in the pollution levels. The use of tree-rings analysis in active volcanic areas has shown that vascular plants could be used as archives of volcanogenic metals deposition. Tree cores of Pinus Nigra and Populus tremula were collected in sites located both on the downwind (Citelli and Mt. Fonta…
Upper thermal threshold of Lepidurus arcticus (Branchiopoda, Notostraca) in lakes on the southern outreach of its distribution range
2021
Qvenild T, Fjeld E, Fjellheim A, Hammar J, Hesthagen T and Lakka H-K. 2021. Upper thermal threshold of Lepidurus arcticus (Branchiopoda, Notostraca) in lakes on the southern outreach of its distribution range. Fauna norvegica 41: 50–88. The Arctic tadpole shrimp Lepidurus arcticus has a circumpolar distribution and the Scandes (Fennoscandian Mountains) marks its southernmost limit in Europe. Within this area, 391 natural and 88 regulated lakes with L. arcticus have been identified, of which 87% are above the treeline. The lakes hosting L. arcticus decrease in altitude from south to north, which results from its temperature preferences. The majority of the locations are at a lower lake air t…
Impianti di trigenerazione per il risparmio energetico nel settore alberghiero in aree mediterranee
2008
Il settore alberghiero presenta prospettive particolarmente favorevoli alla diffusione degli impianti di cogenerazione, grazie alla simultanea presenza di una domanda elettrica e di una termica a bassa temperatura, che consentono, in particolare per gli alberghi che funzionano durante tutto l’anno, significativi risparmi di energia primaria e notevoli benefici sia economici che ambientali. Nei paesi del bacino Mediterraneo, in particolare, la diffusione dei frigoriferi ad assorbimento presenta grandi vantaggi per l’opportunità di integrare, nei cosiddetti impianti di trigenerazione o CHCP, la domanda di energia frigorifera all’interno del processo di “sfruttamento in cascata” del potenziale…
Assessment of the importance of neutron multiplication for tritium production
2016
Abstract One of the major requirements for a fusion power plant in the future is tritium self-sufficiency. For this reason the scientific community has dedicated a lot of effort to research activity on reactor tritium breeding blankets. In the framework of the international project DEMO, many concepts of breeding blanket have been taken into account and some of them will be tested in the experimental reactor ITER by means of appropriate test blanket modules (TBMs). All the breeding blanket concepts rely on the adoption of binary systems composed of a material acting as neutronic multiplier and another as a breeder. This paper addresses a neutronic feature of these kinds of systems. In parti…
Economic and Life Cycle Analysis of Passive and Active Monitoring of Ozone for Forest Protection
2021
At forest sites, phytotoxic tropospheric ozone (O3) can be monitored with continuously operating, active monitors (AM) or passive, cumulative samplers (PM). For the first time, we present evidence that the sustainability of active monitoring is better than that of passive sensors, as the environmental, economic, and social costs are usually lower in the former than in the latter. By using data collected in the field, environmental, social, and economic costs were analyzed. The study considered monitoring sites at three distances from a control station in Italy (30, 400, and 750 km), two forest types (deciduous and Mediterranean evergreen), and three time windows (5, 10, and 20 years of moni…
