The university, driver of innovation

2019

Several universities have recently made the front page of newspapers, televisions, and other media, but, unfortunately, the reason behind this was not their day-to-day work, focused on training and research, but some cases of malpractice by certain academics who used and abused the institution for personal gain. 
 By its very nature as a public service, the University is based on analysis and criticism, including self-criticism. Very few institutions are. Perhaps that is why, without ignoring the fact that there is room for improvement, we must prove the increasingly important role that these public bodies have been given, as well as their achievements for social benefit and progress. …

1D Compression Behaviour of Opalinus Clay

2017

One of the main concerns related to tunnel excavations, drilling operations and wellbore stability in shales is the generation of excess pore water pressure due to changes in mechanical stress; therefore the consolidation of shales is a fundamental process that must be considered. This paper presents a compre- hensive methodology for analysing the compression and consolidation behaviour of shales. An apparatus to perform high-pressure oedometric tests is presented and an analytical method is introduced to analyse the shale consolidation behaviour, which allows information to be gathered on the coeffi cient of consolidation, stiffness, poroelastic properties, and permeability of the tested m…

Role of Stress History on the Swelling-Shrinkage Behavior of Compacted Scaly Clay

2022

Compacted scaly clays are complex geomaterials widely used for the realization of dam cores and waste dump liners. This research aims to investigate the swelling/shrinkage behavior of these geomaterials subjected in an oedometric cell to complex hydromechanical stress paths, including different sequences of cyclic variations of suction and stress. Microstructure investigations, based on scanning electron microscopy (SEM) and mercury intrusion porosimetry (MIP) techniques, highlighted the microstructural characteristics of the material, which are the distinctive microfabric features (particles assemblages and scales) and the double-porosity networks, where micro- and macropores coexist.

Fiscal Adjustments and Business Cycle Synchronization

2013

Using a panel of annual data for 20 countries we show that synchronized fiscal consolidation (stimulus) programmes in different countries make their business cycles more closely linked, especially in the case of fiscal adjustments lasting 2 or 3 years. We also find: (i) little evidence of decoupling when an inflation targeting regime is unilaterally adopted; (ii) an increase in business cycle synchronization when countries fix their exchange rates and become members of a monetary union; (iii) a positive effect of bilateral trade on the synchronization of business cycles

L’organo straordinario di liquidazione e gli organi di governo del comune consustanziali alla sana gestione: un caso di studio

2022

Without wishing in any way to interfere in the substance of the legislation of local authorities in failure, this work concerns the possible contribution that the Extraordinary Liquidation Body (OSL) can make to the municipal government bodies on the rebalancing of a local authority. The starting point of the research project is the formalization of the declaration of bankruptcy approved by the City Council. Its evolutionary prospects are the measures launched in the context of extraordinary management entrusted to a liquidation body at the same time as the preparation of the hypothesis of permanently-rebalanced budget by the competence of the governing bodies in office. In parallel with th…

Libre circulación de inversiones en la Unión Europea en tiempos de COVID-19

2020

Las inversiones extranjeras han fluido como nunca durante las últimas décadas, en el marco de una aceptación generalizada de sus beneficios. Esta situación, sin embargo, comienza a alterarse de forma acelerada en múltiples lugares del planeta. La presencia de un entorno geoestratégico más complejo y la aproximación crítica de muchos Estados hacia la globalización y lo que ella significa, está consolidando una visión más cautelosa hacia la libre circulación de inversiones extranjeras que, entre otros efectos, se plasma en la elaboración de normativas más restrictivas. La Unión Europea es un espacio económicamente integrado, muy abierto a las inversiones extranjeras y dotado además, de una po…

Is Sleep Disruption a Cause or Consequence of Alzheimer’s Disease? Reviewing Its Possible Role as a Biomarker

2020

In recent years, the idea that sleep is critical for cognitive processing has gained strength. Alzheimer’s disease (AD) is the most common form of dementia worldwide and presents a high prevalence of sleep disturbances. However, it is difficult to establish causal relations, since a vicious circle emerges between different aspects of the disease. Nowadays, we know that sleep is crucial to consolidate memory and to remove the excess of beta-amyloid and hyperphosphorilated tau accumulated in AD patients’ brains. In this review, we discuss how sleep disturbances often precede in years some pathological traits, as well as cognitive decline, in AD. We describe the relevance of sleep to memory co…

Lightweight Alloys Recycling and Processing through Innovative Friction Based Direct Technologies

In the last decades, the use of lightweight alloys has been spreading in almost any industrial field thanks to the relevant weight reduction allowed by the use of such materials. On the other hand, aluminium alloys are characterized by high-energy demands primary production cycles that are responsible for a relevant share of the global CO2 emissions. In order to limit and reverse such phenomenon, putting in place strategies to keep the material in the circle over multiple life cycles is mandatory and the concepts of circular economy, closed loop society and industrial symbiosis are progressively gathering more and more pace. Nevertheless, metal scraps are often mainly composed of chips resu…

Progresses in multi-materials billet manufacturing out of metal scraps through friction stir consolidation

2023

Abstract. The evolution of Friction Stir Consolidation (FSC) from recycling towards upcycling technique proved to be one of the excellent solid-state methods for manufacturing functionally graded billets. Multi-material Functional Graded Materials (FGMs) represent a novel class of materials characterized by a gradual change in properties and functions which can be tailored to enhance components performance. Manufacturing techniques play a critical role in achieving the designed compositional and microstructural distribution. Specifically, FSC allows the manufacturing of FGM billets out of metallic chips; the mixing of different metallic chips offers mutually exclusive mechanical properties …
