Improving soil and water conservation and ecosystem services by sustainable soil management practices: From a global to an Italian soil partnership
2020
The UN Sustainable Development Goals (SDGs) identify the need to restore degraded soils in order to improve productivity and the provision of ecosystem services. The aim is to support food production, store and supply clean water, conserve biodiversity, sequester carbon, and improve soil resilience in a context of climate change. Within this framework, in order to achieve the SDGs and to correct land management in the long-term, soil management is considered mandatory. The reduction of land degradation should be based on various sustainable soil management practices that improve and maintain soil organic matter levels, increase water infiltration, and improve soil water management. This tec…
Echolocating Whales and Bats Express the Motor Protein Prestin in the Inner Ear: A Potential Marker for Hearing Loss.
2020
Prestin is an integral membrane motor protein located in outer hair cells of the mammalian cochlea. It is responsible for electromotility and required for cochlear amplification. Although prestin works in a cycle-by-cycle mode up to frequencies of at least 79 kHz, it is not known whether or not prestin is required for the extreme high frequencies used by echolocating species. Cetaceans are known to possess a prestin coding gene. However, the expression and distribution pattern of the protein in the cetacean cochlea has not been determined, and the contribution of prestin to echolocation has not yet been resolved. Here we report the expression of the protein prestin in five species of echolo…

Effect of weather conditions on somatic cell score in Sicilian Valle del Belice ewes
2010
Mastitis susceptibility of Valle del Belice ewes from the south of Sicily to temperature, humidity, precipitation, solar radiation, sun hours, air pressure, wind-speed and wind-direction measured by a public weather station was investigated using 65,848 test-day somatic cell score (SCS) records of 5,237 ewes. All weather parameters had an effect on SCS in a regression approach. Extreme values of maximum and minimum temperaturehumidity indices resulted in increased SCS. Higher precipitation, solar radiation and sun hours resulted in increased SCS, whereas higher air pressure and wind speed resulted in reduced SCS.
Involucri Traslucidi in Vetromattone: nuove tecniche di assemblaggio a secco ed incremento prestazionale del prodotto per la riduzione del valore di …
2010
Nel corso del Novecento l’impiego dei diffusori di vetro per la realizzazione di elementi tecnici traslucidi in grado di captare la luce naturale ha subito alterne vicende. Dopo un periodo di intenso utilizzo a cavallo del XIX e XX secolo e dopo la realizzazione, in Europa, negli anni a cavallo tra le due guerre, di alcuni edifici divenuti emblematici del Movimento Moderno, l’impiego di questo prodotto “innovativo” per l’epoca, venne progressivamente “relegato” alle parti più nascoste degli edifici per la “pragmatica” risoluzione di problematiche legate, ad es., alla presenza di particolari vincoli urbanistici senza che, quindi, ne venissero ulteriormente indagate le potenzialità espressive…
MIGLIORAMENTO TECNOLOGICO-PRESTAZIONALE DI UN COMPONENTE INNOVATIVO PER L’INVOLUCRO EDILIZIO - PERFOMANCE IMPROVEMENT OF AN INNOVATIVE BUILDING COMPO…
2016
L’articolo illustra l’attività di ricerca che gli autori, cofounder della SBskin. Smart Building Skin s.r.l., start up innovativa e spin off accademico dell’Università degli Studi di Palermo, stanno conducendo al fine di ottimizzare le performance energetiche di un componente innovativo per facciate e coperture di edifici (dagli stessi brevettato) in grado di ridurre i consumi energetici e di produrre energia pulita dal sole. L’attività che qui si illustra è stata finalizzata all’ottimizzazione del design dei sub-componenti che contribuiscono alla realizzazione dei pannelli traslucidi multifunzionali (realizzati con vetromattoni innovativi, preassemblati a secco e precompressi) ed alla scel…
A longitudinal study of perturbations on gut microbiota of Blattella germanica due to periodic antibiotic treatment
2023
En la naturaleza, la simbiosis es un fenómeno generalizado. Podemos definirla como la interacción biológica estrecha y a largo plazo entre dos o más especies. Aunque la mayoría de las relaciones simbióticas más icónicas suelen ser entre eucariotas, también existen simbiosis que incluyen eucariotas, bacterias y arqueas. Esta tesis se centra principalmente en la simbiosis entre insectos, en concreto, la cucaracha Blattella germanica y su microbiota intestinal. En este tipo de relaciones, los insectos suelen adquirir la capacidad de subsistir alimentándose de dietas pobres en nutrientes gracias al metabolismo procariótico de su microbiota intestinal, y ,a cambio, las bacterias obtienen protecc…
"Lauletaan vaan yhdessä, pojat!" : musiikki ja identiteetti sotiemme veteraanien ryhmämusiikkiterapiassa - etnografis-narratiivinen tutkimus
2016
Studies concerning music and identity have shown that the music which an individual values as important tells stories about the subjective reality of the individual (Lehtonen & Niemelä 1997; Baker & Wigram 2004). Through the use of individualized meaningful music in music therapy, a possibility for raising and evaluating processes connected with identity can be created (Magee & Davidson 2004b). Even recent brain studies have shown these connections. When meaningful music is used activity is observed within deep parts of the brain, suggesting a connection between contextualized meaningful music and activity in the brain where the pleasure and the autobiographical memory centers exist (Buruna…
Tree species recognition in species rich area using UAV-borne hyperspectral imagery and stereo-photogrammetric point cloud
2017
Abstract. Recognition of tree species and geospatial information of tree species composition is essential for forest management. In this study we test tree species recognition using hyperspectral imagery from VNIR and SWIR camera sensors in combination with 3D photogrammetric canopy surface model based on RGB camera stereo-imagery. An arboretum forest with a high number of tree species was used as a test area. The imagery was acquired from the test area using UAV-borne cameras. Hyperspectral imagery was calibrated for providing a radiometrically corrected reflectance mosaic, which was tested along with the original uncalibrated imagery. Alternative estimators were tested for predicting tree…
Strategies, Technologies and Novel Components for the Architectural Integration of Photovoltaics
2015
La ricerca riguarda l'integrazione architettonica del fotovoltaico (FV) per il retrofit energetico del patrimonio edilizio esistente e la costruzione di edifici a energia zero (ZEB). L'obiettivo è lo studio e la successiva definizione di strategie, tecnologie e componenti innovativi per l'involucro edilizio che integrino il fotovoltaico, con particolare attenzione verso le tecnologie fotovoltaiche di nuova generazione. Il lavoro si concentra anche sull'ottimizzazione energetica e sull'analisi delle prestazioni di un componente innovativo per il BIPV (Building Integrated Photovoltaics, letteralmente fotovoltaico integrato negli edifici) utile alla costruzione di involucri edilizi sostenibili…
