Reprocessing of polyethyleneterephthalate and characterisation of monopolymer blends of virgin and recycled polymers
1997
Recycling of polyethyleneterephthalate (PET from bottles is considered by changing both reprocessing machines and the effect of humidity. The rheological and mechanical properties of this recycled material remain very close to that of the virgin material provided that a careful drying is carried out before any melt operation. The reprocessing has been carried out mainly in view of the use of this secondary material in blends with virgin PET-monopolymer or homopolymer blends. Indeed, this use is a common industrial practice to reuse plastic scraps. Most monopolymer blends show properties between those of the two components but in some cases lower than those expected on the basis of an additi…
The ‘grave of the Court Pit’, A rediscovered Bronze Age tomb from Carchemish
2014
This paper examines the British Museum unpublished records related to an Early Bronze (EB) Age pithos burial uncovered a century ago in the Inner Town at Carchemish. The grave, cursorily cited and variously dated (Chalcolithic, EB or even LBA) in the final reports, was described in some detail by Hogarth and Thompson; a precise dating is, however, possible today thanks to the information of paramount importance given by T. E. Lawrence who identified and took a picture of the associated finds, which was recently rediscovered in the Carchemish Archives. The pithos can be now ascribed to the third quarter of the third millennium BC and helps to confirm the recent theory according to which the …
Diffusion of oxygen in cork.
2012
International audience; This work reports measurements of effective oxygen diffusion coefficient in raw cork. Kinetics of oxygen transfer through cork is studied at 298 K thanks to a homemade manometric device composed of two gas compartments separated by a cork wafer sample. The first compartment contains oxygen, whereas the second one is kept under dynamic vacuum. The pressure decrease in the first compartment is recorded as a function of time. The effective diffusion coefficient D-eff is obtained by applying Fick's law to transient state using a numerical method based on finite differences. An analytical model derived from Fick's law applied to steady state is also proposed. Results give…
L'analisi economico aziendale dei risultati di bilancio delle aziende vitivinicole siciliane imbottigliatrici "grandi" nell'esercizio 2020
2021
Abstract The subject of the previous contribution is the analysis of the financial statements of Sicilian large" wineries bottlers, with particular reference to 2020. The conditions of resistance to the pandemic phenomenon still underway were examined, the strategies implemented to counteract the reduction in turnover and the economic results from the twenty-three companies examined. In general, the companies have shown good sealing ability, despite a generalized loss in turnover of around 20%, in a positive recovery currently underway in 2021.
Early Syrian Bottles
2014
Near Eastern archaeologists are accustomed today to labelling as “Syrian bottles” various kinds of oil/perfume fasks that enjoyed a wide popularity in Syria during the 3rd millennium. Owing to the volatile nature of their contents and the lack of archeometric analysis it has not been possible so far to ascertain whether these vessels were scent or unguent vases. Whatever the case, since they have been found far afeld from the core region of production it is clear that they were a luxury item of long-distance trade and are thus today – if possible misattributions are discarded – a valuable indicator of exchange networks and for establishing synchronisms among distant areas of the ancient Nea…
Sustainable design: study of the life cycle assessment of the production and packaging of wine
2003
The object of the study is the identification of the factors that interact with the environment during the production and the packaging of wine. For this aim is use an Economic Input-Output Life -Cycle assessment (EIO-LCA) and I-LCA database to access both the direct and indirect effects of supply chain on the environment and economy. In this phase is examines the impact on the environment by different types of packaging, and transport, the comparisons are made analyses energy, materials consumption and emissions in the environment.

The MAREDAT atlas covers 11 types of plankton, ranging in size from bacteria to jellyfish. Together, these plankton groups determine the health and productivity of the global ocean and play a vital role in the global carbon cycle. Working within a uniform and consistent spatial and depth grid (map) of the global ocean, the researchers compiled thousands and tens of thousands of data points to identify regions of plankton abundance and scarcity as well as areas of data abundance and scarcity. At many of the grid points, the MAREDAT team accomplished the difficult conversion from abundance (numbers of organisms) to biomass (carbon mass of organisms). The MAREDAT atlas provides an unprecedente…
Seawater carbonate chemistry and kelp densities and coral coverages at three study locations and photosynthesis and calcification of corals measured …

Ocean warming is altering the biogeographical distribution of marine organisms. In the tropics, rising sea surface temperatures are restructuring coral reef communities with sensitive species being lost. At the biogeographical divide between temperate and tropical communities, warming is causing macroalgal forest loss and the spread of tropical corals, fishes and other species, termed “tropicalization”. A lack of field research into the combined effects of warming and ocean acidification means there is a gap in our ability to understand and plan for changes in coastal ecosystems. Here, we focus on the tropicalization trajectory of temperate marine ecosystems becoming coral-dominated systems…
Functional consequences of prey acclimation to ocean acidification for the prey and its predator
2016
Ocean acidification is the suite of chemical changes to the carbonate system of seawater as a consequence of anthropogenic carbon dioxide (CO2) emissions. Despite a growing body of evidences demonstrating the negative effects of ocean acidification on marine species, the consequences at the ecosystem level are still unclear. One factor limiting our ability to upscale from species to ecosystem is the poor mechanistic understanding of the functional consequences of the observed effects on organisms. This is particularly true in the context of species interactions. The aim of this work was to investigate the functional consequence of the exposure of a prey (the mussel Brachidontes pharaonis) t…
