Pollutant removal efficiency of a pilot-scale Horizontal Subsurface Flow in Sicily (Italy) planted with Cyperus alternifolius L. and Typha latifolia …
2016
Constructed wetland systems (CWs) are developed biological technologies for the treatment and reuse of wastewater. The aims of this study were to evaluate the treatment performance of a pilot Horizontal Subsurface Flow system (HSSFs), to evaluate the reuse of treated wastewater (TWW) from CWs for the irrigation of giant reed (Arundo donax (L.)) and to assess the effects of TWW on the biomass yield of giant reed grown for pellet production. The research was carried out in Sicily (Italy) in a pilot-scale HSSFs which was fed with urban-treated urban wastewater following secondary treatment from an activated sludge wastewater treatment plant. Giant reed plots were irrigated with TWW from plante…
Per una storia della Settimana Santa a Malta. I gruppi processionali del Venerdì Santo di Valletta
2013
L’articolo ricostruisce la storia dei riti della Settimana Santa e delle processioni per il Venerdì Santo a Malta, in relazione al più ampio contesto mediterraneo e, pertanto, alla tradizione dei pasos in Spagna e dei “misteri” di Trapani ed Erice. Viene evidenziato il ruolo cruciale svolto a partire dalla fine del XVI secolo dai frati Francescani, la cui presenza si rivelò determinante per la nascita e, in seguito, per la diffusione e la fortuna di tali rappresentazioni processionali, anche grazie al fatto che nel corso dei secoli la devozione per la Passione di Cristo a Malta fu alimentata dalla presenza di ben due crocefissi lignei dello scultore siciliano frate Innocenzo da Petralia. In…
Evolution of qualitative characteristics during blueberry fruit storage in a modified atmosphere
2015
The objective of this work was to evaluate the performance of different films to maintain MAP conditions for storing ‘Duke’ blueberries by verifying the evolution of qualitative traits of berries. The fruits were picked manually, individually deposited in polyethylene baskets and immediately transferred (1 h) to the laboratory under chilled conditions (10°C). The experimental storage units consisted of a pallet bag of two different types of film, polyethylene (100 μm) and a biobased film derived from starch (50 μm). The O2 and CO2 transmission rates, measured according to the ASTM F 2622-08 and ASTM F 2476-05 methods at 38°C and 90% RH, were, 2642 and 10654 [cm3/(m2·24 h)], respectively, fo…
MOLECULAR ANALYSIS OF COLLETOTRICHUM SPECIES ASSOCIATED TO OLIVE IN CALABRIA.
2013
A new molecular approach based on the use of genus-specific primers targeting the internal transcribed spacer (ITS) regions of rDNA, was developed and used to study the diversity of Colletotrichum species associated with the olive canopy in the Gioia Tauro plain (Calabria, southern Italy). Representative symptomatic and symptomless samples of leaves, flowers and fruits were collected during 2012 and analyzed by extracting total DNA and amplifying the target region with the genus-specific primers. Amplicons were cloned and sequenced in order to use the ITS as a barcode gene. No Colletotrichum species were detected in the first sampling period (May 28, 2012), whereas around 15% of the analyze…
Factors affecting the diet of Peregrine Falcon in Italy
2016
The diet of top predators can provide useful information on phenology and abundance of their prey. The cosmopolitan and specialist Peregrine Falcon (Falco peregrinus) is an ideal model to assess whether food changes have occurred in the long-term. In this contribution, we reviewed all available literature on Peregrine Falcon diet in Italy which contained 11 detailed datasets useful for our review, and also included analysis of pellets, collected at three breeding sites of Sicily during 2014 and 2015. These data allowed us to shed light on the Peregrine Falcon’s diet over the last forty years (1978-2015). We calculated the numerical and biomass percentage of the resident and not-resident pre…
A comparison of peregrine Falco peregrinus and lanner Falco biarmicus trophic niche in Sicily
2017
Prey availability is a crucial factor for the reproductive success of apex predators and the analysis of their diets can provide meaningful information about the quality of their habitats. In Sicily the declining lanner falcon Falco biarmicus feldeggii and the increasing peregrine falcon Falco peregrines brookei share similar habitats and trophic needs. By studying their current and past diets, we have investigated whether the characteristics of their foraging ecology could explain these different demographic trends. In 2014-2016, we identified 805 peregrine and 250 lanner Vertebrate prey from 15 peregrine and 6 lanner nests, and compared our dataset with previous data from Sicily (Peregrin…
In spermatozoa collected after pellet swim up, when total dna fragmentation is higher than 15%, the normal morphologically spermatozoa population sho…
2020
Study question: We investigated the DNA Fragmentation Index (DFI) in motile normal morphologically spermatozoa comparing samples with total DFI < 15% Vs ≥ 15% collected after pellet swim up Summary answer: In the case of DFI ≥15% the percentage of normal morphologically spermatozoa with fragmented DNA is significantly higher than the population with DFI < 15% What is known already: Intracytoplasmic sperm injection (ICSI) is widely used in the treatment of male infertility. Only morphologically normal spermatozoa are mainly used by embryologists to fertilize an oocyte. Different papers have reported that spermatozoa with apparently normal morphology may have DNA fragmentation. These ev…
Sizing up the role of predators on Mullus barbatus populations in Mediterranean trawl and no-trawl areas
2019
Abstract Fishing leads to drastic changes in ecosystems with a net loss of predatory biomass. This issue has been evidenced from historical ecological studies and from the evaluation of the effects of effective and large marine protected areas. In two fishery reserves off the northern Sicily coast the red mullet Mullus barbatus underwent an impressive biomass increment and a few piscivores fish species recovered after a trawl ban. The red mullet, more than 20% of all demersal fish in the untrawled areas, represented a huge food resource to its potential predators. By contrasting two trawled and two untrawled gulfs we figured out predator - prey relationships through the use of a combined ap…
Diel feeding habits of juveniles of Mullus surmuletus (Linneo, 1758) in the lagoon of the Stagnone di Marsala (Western Sicily, Italy)
1999
Diet composition, feeding rhythm, gastric evacuation rate and daily ration were investigated in juvenile Mulhis surmuletus (Linneo, 1758). Fish were collected in the lagoon of the Stagnone di Marsala in western Sicily, in July 1995, during a 24 h sampling period. Copepoda, Polychaeta, Amphipoda and Tanaidacea were shown to be the most frequent prey items. The feeding index values showed two different daily feeding times. A unimodal trend in the daily rhythm of food consumption was derived, with a peak in feeding between 1200 and 2000 h. Gastric evacuation in juvenile M. surmuletus is best described by an exponential model, with a gastric evacuation rate R = 0.66 g h-1 (r = 0.88) (T = 24.45 …
L'invenzione nel quotidiano
2018
Michel de Certeau in the book "The Practice of Everyday Life" proposes the dimension of creativity as a widespread and multidirectional process, fueled by social dynamics and individual "tactics", able to evade and transform the sense and the objectives of knowledge and institutional powers. The text sets out some elements of the complex thought of the French scholar, useful to enrich the debate, the language and the visions of contemporary design. In fact nowadays the notions of "invention" and "everyday life" are recurrent in the design discourse, especially with reference to the emergence of a society founded on the diffusion of network technologies, data accumulation, artificial intelli…
