3D-Reconstruction of a Giant Posidonia oceanica Beach Wrack (Banquette): Sizing Biomass, Carbon and Nutrient Stocks by Combining Field Data With High…
2022
Beach wracks are temporary accumulations of vegetal detritus that can be found along coastlines all over the world. Although beach wracks are often perceived as a nuisance for beach users, they play a crucial ecological role in carbon and nutrient connectivity across ecosystem boundaries, especially when they reach a relevant size, as in the case of the wedge-shaped seagrass accumulations called banquette. In this study, three-dimensional mapping of a giant Posidonia oceanica banquette was carried out for the first time using high-resolution UAV photogrammetry combined with field sampling and compositional and chemical analysis. The combined approach allowed a reliable estimation of the amo…
Immediate biomarker responses to benzo[a]pyrene in polluted and unpolluted populations of the blue mussel (Mytilus edulis L.) at high-latitudes.
2008
Immediate biomarker responses of two high-latitude populations of the blue mussel Mytilus edulis to benzo[a]pyrene (B[a]P) were evaluated. Mussels collected from a clean and a polluted site in southwest Iceland were exposed to the nominal dose of 100 μg B[a]P L−l for 3 h, after 4 days of acclimatization in clean seawater. To test the sensitivity to the toxicant and immediate biological responses, the following biomarkers were used: DNA single strand breaks, heart rate and feeding rate.All the biomarkers revealed differences between the study sites. Irrespective of the origin of the organisms, the short time exposure to the high B[a]P concentration did not induce DNA single strand breaks or …

A new sustainable formulated feed based on discards from food industries for rearing the sea urchin Paracentrotus lividus (Lmk)
2019
During a 18‐week experiment in a sea‐based system, Paracentrotus lividus was fed with two formulations of a new sustainable feed whose main ingredients were food farming discards, mostly outermost lettuce leaves, in different percentage. Egg white was added as protein source and binder, and a little amount of commercial fish feed was added as lipid source. At the end of the experiment, a high survival rate (>80%) and an increase in test diameter (22%), total weight (130%), gonad weight (240%) and gonad index expressed as size‐adjusted gonad weight (288%) were recorded. Gonads achieved a good colour and high levels of essential and polyunsaturated fatty acids, hence representing a commerc…

Il tessuto del mare. Manfredonia. Blue in green
2010
Alcuni cliché descrittivi, adoperati per la città contemporanea, sembrano potersi usare ovunque sia necessario tratteggiare caratteri urbani privi di qualunque specificità. Fra le valutazioni stereotipate prevale quella della città-caos, soprattutto quando la struttura urbana si presenta come unica nebulosa antropica in cui è impossibile identificare i diversi nuclei urbani che la compongono. Tale condizione sembra essere del tutto estranea alla realtà di Manfredonia che è nettamente distinta dagli altri centri che insistono sull'ampia pianura del Gargano. Il saggio si occupa criticamente degli esiti del workshop svolto a Manfredonia dal 9 al 13 settembre 2009 dal titolo "Il Golfo di Manfre…
Offloading through Opportunistic Networks with Dynamic Content Requests
2014
Offloading is gaining momentum as a technique to overcome the cellular capacity crunch due to the surge of mobile data traffic demand. Multiple offloading techniques are currently under investigation, from modifications inside the cellular network architecture, to integration of multiple wireless broadband infrastructures, to exploiting direct communications between mobile devices. In this paper we focus on the latter type of offloading, and specifically on offloading through opportunistic networks. As opposed to most of the literature looking at this type of offloading, in this paper we consider the case where requests for content are non-synchronised, i.e. users request content at random …
A Dynamic System for Personal Communications: The Opportunistic Chat
2007
most of currently available inter-personal instant messaging systems are client-server based. Users of such systems need to be connected to some centralized entity which goal is to supply them with information needed to make the communication possible, such as the list of connected users, their status, and the address of their devices. Our proposed system for an “Opportunistic Chat” allows people to exchange written messages over Bluetooth and (if necessary) TCP/IP connections, with no need of any kind of centralized entity, by using ad-hoc procedures, automatically selected and operated. Such system can be accessed almost from any kind of device, either mobile or not, ranging from personal…
