Modifications over years of volatile compounds and agronomic features in a Sicilian Clary sage biotype.
2006
Clary sage is a biennial native to Mediterranean area, spontaneous and often ubiquitous in many environments of inner Sicily. The large white-pinkish flowers are used, besides for ornamental purposes, for extracting a strongly-scented essential oil largely used by perfume industries. This work has been carried out with the aim to observe over several years the behaviour of a Sicilian Clary sage biotype, grown on experimental plots laid out in Sparacia (Cammarata - AG - Sicily). For this purpose seeds of Clary sage collected from a wild population growing in Pietraperzia (EN) were sown in experimental plots each year for seven consecutive years (from 1998 to 2005). Since Clary sage is a bien…
Conservazione del suolo e politiche di sviluppo nella programmazione comunitaria 2014-2020: Le aree interne.
2014
During the next EU programming, Italy will suggest to commit a substantial portion of the funds to the development of the inland areas. This will happen through a structured program that will interact, since its start-up, with the local subjects in order to combine and to bind the development with the territory. The maintenance of the territory together with the involvement of the local communities focus the attention on the management of the common goods. The debate is still open and the inland areas policy which is built up by the Department for Development and Economic Cohesion (formerly the Department for Development Policy and Cohesion) of the Ministry of Economic Development, does not…
Concentración vs dispersión de los inmigrantes en Italia. Análisis comparativo sobre la distribución de la población extranjera en las regiones urban…
2015
Según Soja (2011) los procesos de urbanización regional que en los últimos treinta años han caracterizado las transformaciones de las grandes áreas urbanas del mundo señalan el fin de la metrópolis moderna. Tales procesos están acompañados por una transformación socio-espacial de los asentamientos urbanos, caracterizada por nuevos y elevados niveles de fragmentación socio-económica. En cuanto a este fenómeno, la polarización social densa, típica de los espacios urbanos de la ciudad fordista, ha dado paso a una geometría social “desestructurada” y “dispersa”. Esto ha cuestionado los tradicionales modelos de análisis de las geografías de concentración socio-espacial, propios del enfoque funci…
Rethinking inner areas. A multidisciplinary approach to the revival of the territories.
2022
[...] Our little villages have never been as interesting as they are now, they have the feel of the past and still manage to take in even the atmosphere of this time. They have strengths and intensities that we don’t know how to draw on because we don’t look at them, we don’t know how to love them. [...] There is discomfort, there is loneliness, but there is also beauty. This is the starting point, the proper use of our ruins. [...] - Per un buon uso delle nostre rovine, from the book “Terracarne”, 2011, Franco Arminio
La street art come motore di recupero e rigenerazione urbana delle aree interne. Un progetto condiviso per lo sviluppo di smart villages nell'area Ma…
2022
The Madonie district, one of the 72 pilot areas of the National Strategy for Inner Areas in Italy in the center of Sicily, is composed by 21 municipalities that really have a great potential, due to their historical background and natural landscape, but it needs new strategies to emerge. Many people from northern cities have returned to their home villages in recent years, to live and work, but they have not found some important and necessary services as there are in smart cities, and to date, these villages do not adopt smart strategies. Many changes need to be made, one solution is to transform them into smart villages through rehabilitation, such as improving the historic center with str…
Silver-loaded nanoparticles affect ex-vivo mechanical behavior and mineralization of dentin
2019
Background: The aim was to evaluate the effect of silver loaded nanoparticles (NPs) application on the triboscopic, crystallographic and viscoelastic properties of demineralized dentin. Polymethylmetacrylate-based NPs and Ag loaded NPs were applied on demineralized dentin. Material and Methods: Treated and untreated surfaces were probed by a nanoindenter to test viscoelasticity, and by atomic force microscopy to test nanoroughness and collagen fibril diameter. X-ray diffraction and transmission electron microscopy through selected area diffraction and bright-field imaging were also used. Results: Dentin treated with Ag-NPs attained the lowest complex modulus, and the highest tan delta value…
Distribution of calcitonin gene-related peptide-like immunoreactivity in the brain of the lizardPodarcis hispanica
2002
The present work studies the distribution of calcitonin gene-related peptide-immunoreactive (CGRP-li) neurons and fibers in the brain of a reptile, the lizard Podarcis hispanica. CGRP-li perikarya were not present in the telencephalon. In the thalamus, CGRP-li perikarya were restricted to the posteromedial and posterolateral nuclei. In the hypothalamus, CGRP-li cells were found mainly in the supramammillary and mammillary nuclei. In the midbrain and brainstem, CGRP-li cells appeared in the ventral tegmental area, the parabrachial nucleus, and the motor nuclei of the III-VII, IX, X, and XII cranial nerves. Motoneurons of the ventral horn of the spinal cord were also immunoreactive for CGRP. …
The Fundamental Role of Melanocortins in Brain Processes
2003
The discoveries of the latest ten years have shed new light in understanding the roles of melanocortins and their receptors in brain functions and in the development of different pathologies. Since 1992 when genes encoded melanocortin receptor five subtypes were identified, cloned and characterized, the molecular mechanisms underlying different effects such as skin darkening, behaviour, food intake, anti-inflammatory action, analgesia have been clarified. The contribution of melanocortins and their receptors in the physiological control of organism homeostasis has become as the background for the search of agonists and antagonists of separate receptor subtypes, that can be targeted to the m…
La resistenza di interfaccia calcestruzzo poroso-terreni a grana fina per il consolidamento di pendii mediante trincee drenanti profonde
2022
Le trincee drenanti profonde rappresentano uno dei metodi più efficaci per la mitigazione del rischio da frana, in pendii con falda idrica. Esse sono realizzate mediante pannelli o pali secanti. Il riempimento è costituito di calcestruzzo poroso o materiale granulare. Se le trincee sono adeguatamente “innestate” nel terreno stabile e il materiale di riempimento ha sufficiente resistenza e rigidezza come il calcestruzzo poroso, si ha ulteriore in-cremento di resistenza a taglio per effetto shear keys, oltre a quello derivante dalla riduzione delle pressioni in-terstiziali. L’incremento di resistenza è dovuto sia alla resistenza all’interfaccia calcestruzzo–terreni sia a quella intrinseca del…
The British-Irish Border in the Context of Brexit
2020
Przedmiot artykułu stanowią rozważania dotyczące konsekwencji Brexitu dla funkcjonowania granicy pomiędzy Irlandią a Irlandią Północną. Autor wyjaśnia, czym jest ta granica w warunkach, kiedy Wielka Brytania nie jest już członkiem Unii Europejskiej, a więc przebieg tej granicy może stanowić barierę dla swobodnego przepływu osób, towarów, kapitału i usług. Artykuł jednocześnie podkreśla, że wyjście Wielkiej Brytanii z Unii Europejskiej będzie miało istotny wpływ na zmianę funkcji tej granicy, która od tej chwili nie będzie już wewnętrzną, lecz zewnętrzną granicą Unii. Celem artykułu jest zatem analiza konsekwencji tej zmiany z równoczesnym wskazaniem różnych modeli funkcjonowania Wielkiej Br…
