Polyp flats, a new system for experimenting with jellyfish polyps, with insights into the effects of ocean acidification
2014
Research interest on jellyfish has grown exponentially over the last years and studies focusing on the biology and ecology of the jellyfish polyp stage are being recognized as crucial in understanding jellyfish proliferations. Due to the difficulty of conducting in situ work with jellyfish polyps, laboratory experiments are the most used approach. Here, we describe the design and successful testing of a new system that allows continuous seawater renewal while keeping constant the selected physicochemical conditions of the water throughout the experiment in contrast to closed systems used previously. As a first test, we started an experiment to assess the effects of ocean acidification on th…

La salute delle strutture molli e dure del cavo orale è essenziale non solo per preservare le funzioni ad esse direttamente associate, ma anche per promuovere la salute generale dell’organismo. Tra le problematiche di maggiore interesse clinico a carico della cavità orale ritroviamo: i) le complicazioni post-operatorie che possono verificarsi a seguito di comuni avulsioni dentali che, se non trattate tempestivamente, possono sfociare in gravi parodontiti; ii) i fenomeni di osteonecrosi a carico di mascella e mandibola associate a trattamenti farmacologici nonché alla radioterapia; iii) il carcinoma orale a cellule squamose (OSCC) che è tra i più aggressivi tumori del collo e della testa, ca…

Edible Insects an Alternative Nutritional Source of Bioactive Compounds: A Review
2023
Edible insects have the potential to become one of the major future foods. In fact, they can be considered cheap, highly nutritious, and healthy food sources. International agencies, such as the Food and Agriculture Organization (FAO), have focused their attention on the consumption of edible insects, in particular, regarding their nutritional value and possible biological, toxicological, and allergenic risks, wishing the development of analytical methods to verify the authenticity, quality, and safety of insect-based products. Edible insects are rich in proteins, fats, fiber, vitamins, and minerals but also seem to contain large amounts of polyphenols able to have a key role in specific bi…
Oltre i confini: verso la regionalizzazione dell'urbano. W 1.2 Il paradigma bio-regionale per il progetto di ri-territorializzazione (re-embedding) d…
2019
Il capitolo rende conto di una rilettura ed interpretazione del paradigma bio-regionale come riferimento per pratiche interpretative, di governance e progetto di territorio finalizzate alla “ril-ocalizzazione” dell’insediamento umano nel suo milieu socio-culturale ed ambientale di prossimità. Il riferimento primario è all’ampio e polifonico movimento culturale bio-regionale sviluppatosi in particolare negli Stati Uniti tra la fine degli anni sessanta e l’inizio degli anni settanta del XX secolo.
Polypropylene/graphene nanoplatelets nanocomposites subjected to elongational flow
2018
In this work the effect of the presence of graphene nanoplatelets (GnP) on the morphology and mechanical properties of polypropylene/GnP nanocomposites has been investigated when these polymer systems are subjected to non-isothermal elongational flow in a melt spinning operation. The presence of the GnP magnifies the effect of the elongational flow. Indeed, the elastic modulus and the tensile strength increases with the orientation more than that observed for the pure matrix.
Photo-oxidative behavior of PP/GnP nanocomposites
2018
In this work the photo-oxidative behavior of neat polypropylene (PP) and PP based nanocomposites incorporating graphene nanoplatelets (GnP) was studied. In particular, the influence of the amount of incorporated GnP was evaluated. The photo-oxidation has been followed by monitoring the change of the rheological, mechanical and spectroscopic properties upon artificial exposure to UV-B light. The results revealed that the presence of GnP reduced the rate of photooxidation of the PP matrix and, in the investigated composition range, the photo-stabilizing action improved with increasing the GnP content.
