Impact of Plastic Debris on the Gut Microbiota of Caretta caretta From Northwestern Adriatic Sea
2021
Plastic pollution is nowadays a relevant threat for the ecological balance in marine ecosystems. Small plastic debris (PD) can enter food webs through various marine organisms, with possible consequences on their physiology and health. The loggerhead sea turtle (Caretta caretta), widespread across the whole Mediterranean Sea, is a “flagship species,” useful as indicator of the general pollution level of marine ecosystems. Ingested PD accumulate in the final section of turtles’ digestive tract before excretion. During their transit and accumulation, PD also interact with the residing microbial community, with possible feedback consequences on the host’s health. To explore the possible relati…
Social Harmony or a Happy Society
2021
In this paper, I set out to prove that once we correctly identify human nature and organize our world according to the principle of cooperation, we can arrive at a world of social harmony. We can then engage in conscious human evolution, aiming at moral and intellectual perfection. Hence, we can arrive at evolutionity, a new evolutionary epoch which would replace the current conflicting and disharmonious times of postmodernity. The current world disharmony, which can be observed especially in the field of politics and economics, is largely related to the erroneous modern Western philosophical assertions identifying the human being with an individual moved by desires and the will to power, a…
PRIMO LEVI E LA QUESTIONE DELL’ANIMALITÀ
2020
The approach of man and animal in Levi’s work can lead to some simplifications. We could think of a naturalization operation: man is one of many animals. Or, on the contrary, we could think of a culturalization: the animal is a social being. In reality, the ontological principle on which Levi’s thinking and writing are based is that of analogy. Assuming the hypothesis of the anthropologist Philippe Descola, this essay proposes an analogical reading of Levi. Focusing on a precise story, Censura in Bitinia, I will try to discuss this interpretative hypothesis.
The role of biotic interactions in a prey-predator system : the case of predation and regulation of weed seeds by carabids.
2020
For the transition towards agricultural production systems that are less dependent on herbicides, the use of weed regulation by seed-eating carabids is of great interest. Weed seed predation by carabids is variable and occurs within a complex context of many biotic interactions. This complexity partly explains our current inability to predict levels of in-field weed regulation. In this thesis, I analysed variations in the levels of predation and biological regulation of weeds and determined how they respond to two classes of biotic interactions: 1) the availability of alternative prey; and, 2) intra- and inter-specific interactions between the carabids themselves. Field measurements carried…
Il paesaggio come materia fondativa del progetto
2017
Il contributo affronta il tema del rapporto tra architettura e natura attraverso il ruolo strutturante che il paesaggio antropizzato riveste per quel tipo di progetto che basa la propria essenza costitutiva sulla dimensione fisica e spirituale dei luoghi; in tal senso, il paesaggio è inteso quale finalità principale dell’architettura. Ad esplicitazione dei concetti espressi, si prendono in esame gli esiti della ricerca progettuale condotta dall’autore nell’ambito del proprio laboratorio di progettazione architettonica, destinato allo sviluppo delle tesi di laurea, incentrato sul tema L’architettura nella roccia e operante intorno ai concetti dello scavo, della sottrazione, del progetto del …
Timing and patterns of the ENSO signal in Africa over the last 30 years: insights from normalized difference vegetation index data.
2014
Abstract A more complete picture of the timing and patterns of the ENSO signal during the seasonal cycle for the whole of Africa over the three last decades is provided using the normalized difference vegetation index (NDVI). Indeed, NDVI has a higher spatial resolution and is more frequently updated than in situ climate databases, and highlights the impact of ENSO on vegetation dynamics as a combined result of ENSO on rainfall, solar radiation, and temperature. The month-by-month NDVI–Niño-3.4 correlation patterns evolve as follows. From July to September, negative correlations are observed over the Sahel, the Gulf of Guinea coast, and regions from the northern Democratic Republic of Congo…
L'utilisation des reliefs naturels dans l'art gravé et sculpté pariétal du paléolithique supérieur français
2005
Pendant toute la durée du Paléolithique supérieur, en Espagne et en France principalement, les artistes ont réalisé des figurations en utilisant les reliefs naturels et la morphologie des parois de grottes ou d'abris-sous-roche. Ce phénomène artistique, qui a toujours préoccupé les préhistoriens, a suscité les interrogations et les interprétations les plus diverses de la fin du XIXe siècle jusqu'à présent : origine de l'art, préoccupations magico-religieuses, organisation spatiale et sanctuarisation de l'espace souterrain, structures pariétales, chamanisme, techno-cultures, etc. Pendant longtemps, ce que les formes rocheuses pouvaient avoir d'évocateur a été considéré comme la raison d'être…
Valorization of Marine Waste: Use of Industrial By-Products and Beach Wrack Towards the Production of High Added-Value Products
2021
Biomass is defined as organic matter from living organisms represented in all kingdoms. It is recognized to be an excellent source of proteins, polysaccharides and lipids and, as such, embodies a tailored feedstock for new products and processes to apply in green industries. The industrial processes focused on the valorization of terrestrial biomass are well established, but marine sources still represent an untapped resource. Oceans and seas occupy over 70% of the Earth’s surface and are used intensively in worldwide economies through the fishery industry, as logistical routes, for mining ores and exploitation of fossil fuels, among others. All these activities produce waste. The other sou…
