Analisi strutturale per lo studio del danneggiamento in materiali e strutture complesse

The aim of the project is to investigate issues related to the study of structural resilience and damage processes in complex materials, with the goal of providing a significant contribution from both a scientific and an applied perspective. Following an extensive bibliographic review and an in-depth analysis of the scientific literature on resilience, defined as the ability of a system to restore its equilibrium condition after an external intervention or a reduction with respect to its loa...

The case of Rebuffoichnus in Lanzarote: ichnological and neoichnological approaches to the study of insect trace fossils from the Pleistocene

The purpose of this work is to clarify the origin of the insect trace fossils found in the Quaternary deposits of Lanzarote, providing new data and refining our knowledge of this ichnospecies (Rebuffoichnus ispp.). The research focuses on four aspects. Firstly, new localities from Lanzarote bearing specimens of Rebuffoichnus ispp. are here described along with the stratigraphy of the deposits; secondly, neoichnological studies have been conducted through micromorphology and tomography to comp...

Integrated remote sensing and ecological modeling of drought- and pathogen-induced forest decline in Mediterranean ecosystems

Mediterranean forests are one of the main biodiversity reservoirs in the world and play a fundamental role providing essential ecosystem services. However, these ecosystems, shaped by centuries of interaction with humans, are now among the most vulnerable to the effects of climate change. Increasing drought frequency, heat waves, and the spread of plant pathogens, particularly Phytophthora species, are profoundly altering forest structure, functionality, and regeneration, contributing to wide...

NEUROPSICOBIOLOGIA DEI DISTURBI DELL’UMORE: CONNESSIONI TRA PROCESSI AFFETTIVI E VIE MOLECOLARI

Background: Bipolar Disorder (BD) and Major Depressive Disorder (MDD) are chronic, recurrent mood disorders marked by clinical and biological heterogeneity, diagnostic uncertainty, and progressive neurobiological impairment. Contemporary research highlights their systemic nature, where mood dysregulation arises from interconnected processes involving mitochondrial dysfunction, immune imbalance, and altered neuroplasticity. Methods: A multimodal design was implemented to assess three biologica...

Valorisation of Myrtle Liqueur Processing and Olive Pomace By-products as Ingredients for Functional Dairy Foods

This research has deepened the potential for valorisation of by-products of the Sardinian agri-food industry, in particular olive pomace (OP) and exhausted myrtle berries (MSB), for the formulation of functional yogurts based on whole sheep's milk. The activity was developed with a view to sustainability and the circular economy, with the aim of creating an innovative product capable of combining nutritional benefits, the best chemical-physical, rheological and sensorial properties. The expe...

STUDY OF THE NUTRITIONAL CAUSES OF MILK FAT DEPRESSION IN GRAZING SHEEP: THE CASE OF WATER-SOLUBLE CARBOHYDRATES OVERLOAD FROM GRASSES

The decrease in milk fat content observed in dairy sheep farms in Sardinia is an important issue of the last decades, particularly during winter and spring months. In grazing conditions, the common use of modern tetraploid annual ryegrass varieties rich in water soluble carbohydrates (WSC) may be one of the causes of milk fat depression (MFD) due to subacute ruminal acidosis in ewes grazing on these pastures. The findings of the first study, in which the milk fat content of ewes fed unshaded ...

Reverse engineering per lo scavo stratigrafico: dalla modellazione 4D alla simulazione interpretativa

Since its origins, Digital Archaeology has placed the prospects offered by the three-dimensional representation of the physical entities of an archaeological excavation at the centre of international academic debate. Initially addressed on a theoretical level and later through practical attempts, this field has produced an increasing variety of advanced digital infrastructures capable of containing, visualising, manipulating and analysing archaeological data. Over time, the challenge of thre...

The present research project focused on two aims. The first concerned the definition and empirical validation of a scale for measuring restorative attitudes, which led to the identification of five fundamental dimensions of the construct. The second aim concerned the assessment of the impact of a restorative justice programme in a secondary school in northern Sardinia. The results of the study ...

Le relazioni tra la Sardegna e la Penisola Iberica tra il Bronzo Finale e la prima età del Ferro attraverso le testimonianze archeologiche (secoli XII - VII a. C.)

The thesis titled “Le relazioni tra la Sardegna e la Penisola Iberica tra il Bronzo Finale e la prima età del Ferro attraverso le testimonianze archeologiche (secoli XII–VII a.C.)” fits within the broader framework of Protohistoric Mediterranean navigation and contacts, with particular reference to the island of Sardinia and the Iberian Peninsula. It seeks to reconstruct the relationships that developed between these two areas during the Late Bronze Age and the Early Iron Age, based on materi...
