Modelos de gestión en áreas comerciales urbanas: centros comerciales abiertos en España
2014
Los partenariados públicos-privados (PPP) en áreas comerciales urbanas son proyectos de cooperación entre la administración pública y los comerciantes locales que persiguen un mismo objetivo: la recuperación funcional y económica de una determinada área urbana. Desde su nacimiento en Norteamérica, los PPP han ido adaptándose a la estructura empresarial, cultural y política de su entorno regional. España, que adoptó este tipo de proyectos de PPP más recientemente, se encuentra en la actualidad en un momento decisivo para replantear la fórmula de gestión y financiación de sus proyectos ya consolidados.
The Four Axes of Palermo’s Commerce: a Geographical Perspective
2021
Le dinamiche commerciali all’interno della città rappresentano un ottimo punto di osservazione per studiare i processi di trasformazione urbana. Queste dinamiche riflettono verticalità e orizzontalità dei sistemi di relazione, nonché scambi e reciprocità dei rapporti socio-economici e culturali. Da una prospettiva geografica è di grande interesse individuare permanenze e mutazioni culturali, sociali, economi- che che costituiscono il tessuto cittadino e danno forma all’attualità. Questo contributo nasce nell’ambito del Progetto di Rilevante Interesse Nazionale (PRIN) 2015 “Commercio, consumo e città: pratiche, pianificazione e governance per l’inclusione, la resilienza e la sostenibilità ur…
Servicios educativos y sanitarios elementales en el medio rural: percepción social e influencia sobre la calidad de vida
2012
One of the main characteristics of rural areas is a higher quality of life. However, the basic aspects of the social structure, e.g. the basic education and health-care services, are barely responsible for the wellbeing of the society, although the necessity of improving their offer is continually emphasised. Consequently, it is interesting to discover how the rural population actually values the capacity of these services to intervene in their quality of life. Logically, because of the diversity of spaces that constitute the rural areas, the results vary; at least that is what the analysis of the interviews of various key actors shows: while the services are crucial for the municipalities …
Effects of the gill parasite Zeuxapta seriolae (Monogenea: Heteraxinidae) on the amberjack Seriola dumerili Risso (Teleostei: Carangidae)
2004
Zeuxapta seriolae (Monogenea: Heteraxinidae) infection was associated with important mortalities of amberjacks (Seriola dumerili) reared in tanks in the experimental facilities of the Spanish Institute of Oceanography (Western Mediterranean) during the period 1998–2000. Fish infested by this parasite presented characteristics similar to those described for Seriola quinqueradiata parasitized by Heteraxine heterocerca in Japan. All dead amberjacks had high parasite abundance (mean abundance±S.D.=686.7±125.4) and egg strings entangled in gills. The parasitological analysis of 17 live amberjacks collected from the infested tanks showed that 41.2% of fish harboured Z. seriolae with intensities r…
Turning waste into gold: Sustainable feed made of discards from the food industries promotes gonad development and colouration in the commercial sea …
2021
Abstract Development of sustainable aquaculture practices is a suitable solution to reduce the pressure on overexploited stocks of the Mediterranean sea urchin, Paracentrotus lividus, and to respond to the increasing market demand. To move forward the Blue Growth and following the principles of circular economy, a three-month feeding experiment was conducted to test a sustainable feed based on food processing discards on sea urchins. Two feed formulations differing on the proportions of the two main ingredients (endive outermost leaves and European anchovy discards in a ratio of 60:40 and 80:20 respectively) were prepared and tested on P. lividus gonad yield, development and quality. The re…
L’architettura gotica in Sicilia centro-orientale nelle perizie degli architetti d’età moderna
2018
L’ARCHITETTURA GOTICA IN SICILIA CENTRO-ORIENTALE NELLE PERIZIE DEGLI ARCHITETTI D’ETÀ MODERNA Il contributo si concentra sulla percezione e sulla valutazione da parte degli architetti siciliani d’età moderna di opere costruite sull’isola in età gotica. L’occasione del confronto emerge soprattutto dalle perizie redatte durante l’elaborazione di nuovi progetti (di ammodernamento, di completamento) che contemplano la salvaguardia o la distruzione delle strutture del passato. Le relazioni selezionate in questa occasione affrontano pertanto questioni di carattere prevalentemente estetico e di linguaggio, ma anche le ragioni inerenti alle strutture e quelle relative alle economie (di cantiere, d…
Sea urchin coelomocytes as a novel cellular biosensor of environmental stress: a field study in the Tremiti Island Marine Protected Area, Southern Ad…
2007
The aim of the present study was to investigate on the suitability of the sea urchin as a sentinel organism for the assessment of the macro-zoobenthos health state in bio-monitoring programmes. A field study was carried out during two oceanographic campaigns using immuno-competent cells, the coelomocytes, from sea urchins living in a marine protected area. In particular, coelomocytes subpopulations ratio and heat shock protein 70 (HSC70) levels were measured in specimens of Paracentrotus lividus (Lamark, 1816) collected in two sampling sites, namely Pianosa and Caprara Islands, both belonging to the Tremiti Island Marine Protected Area (MPA) in the Southern Adriatic Sea, Italy. By density g…
Early cardiac unloading with ImpellaCP™ in acute myocardial infarction with ventricular septal defect
2020
Abstract Despite a relative contraindication, mechanical support with Impella™ left ventricular assist device has already been described for ischaemic ventricular septal defect treatment, either as a bridge to surgery, as intraoperative mechanical haemodynamic support, or to ensure intraprocedural haemodynamic stability during device closure. We describe two cases of ventricular septal defect complicating acute myocardial infarction, where the percutaneous ImpellaCP was implanted early (differently than previously described) with the aim of preventing haemodynamic instability, while deferring surgical repair. We present a report of haemodynamic, echocardiographic, biochemical, and clinical …
Sequence of lethal events in HeLa cells exposed to the G2 blocking cytolethal distending toxin
2000
The bacterial cytolethal distending toxin (CDT) was previously shown to block the cell cycle of several cell lines at stage G2 through inactivation of the cyclin-dependent kinase Cdkl and without induction of DNA strand breaks. In the present study, we have analyzed, using various methods of analytical cytometry, the progressive transformation and delayed lethal events in the tumor-derived HeLa cell line temporarily exposed to CDT. The cell proliferation arrest induced by CDT was irreversible but, starting about two days after exposure, the G2 block released partially, concomitantly with a decline in the level of Cdkl phosphorylation. This partial release resulted in endoreduplication, lead…
Mapping Retrotransposon LINE-1 Sequences into Two Cebidae Species and Homo sapiens Genomes and a Short Review on Primates
2022
This work focuses on the distribution of LINE-1 (a Long Interspersed Nuclear Element) in primates and its role during evolution and as a constituent of the architecture of primate genomes. To pinpoint the LINE-1 repeat distribution and its role among primates, LINE-1 probes were mapped onto chromosomes of Homo sapiens (Hominidae, Catarrhini), Sapajus apella, and Cebus capucinus (Cebidae, Platyrrhini) using fluorescence in situ hybridisation (FISH). The choice of platyrrhine species are due to the fact they are taxa characterised by a high level of rearrangements; for this reason, they could be a useful model for the study of LINE-1 and chromosome evolution. LINE-1 accumulation was found in …
