Analysys and optimization of an end double-lap bonded joint for GFRP composite sandwich panels

2022

Although the best configuration of the joints used to connect a common GFRP sandwich panel with the main structures is the adhesively bonded one, that permit high static and fatigue performances as well as to avoid stress concentrations, mechanical or hybrid joints are still widely used in the industrial field. After a preliminary theoretical design, the optimal configuration of an end adhesively bonded double-lap joint constituted by a simple insert as internal adherent and the same face sheets as external adherent, has been researched. In detail, several experimental tests and successive numerical simulations under tensile and bending loading, performed by varying the main influence para…

The assessment over time of the performance of jute-basalt hybrid composites for cladding panels

2017

The technology of dry assembly to produce multi-layer panels is an efficient alternative to traditional systems. Eco-sustainable systems are increasingly studied, particularly fiber reinforced composites for external cladding, based on natural fibers. Nevertheless, durability data on these composites are still lacking, being this is a really actual theme, especially for their potential use in outdoor applications. In this way, hybridization of natural fibers with mineral fibers as basalt ones appears promising. In the present paper, the performance of jute-reinforced laminate was compared with those of two jute/basalt reinforced hybrid laminates. The laminates were manufactured by means of …

La selezione dei giudici della Corte di giustizia dell'Unione. Nuove prospettive di integrazione e legittimazione.

2014

Abstract The appointment of judges to supranational and international courts has long been a neglected area of sovereign activity. However, the growing role and significance of the European Court of Justice (ECJ), by now one of the most significant players within the European political and constitutional space, demands reforms which also affect its architecture. The creation of the advisory panel under article 255 TFUE, whose task is to provide the Council with opinions on candidates suitability, it could be considered one of the most interesting novelties introduced by the Lisbon Treaty. Indeed, the panel is definitely a way to improve judicial independence and proficiency but also a means…

The role of online social comparison as a protective factor for psychological wellbeing: A longitudinal study during the COVID-19 quarantine

2021

During the COVID-19 pandemic crisis, the experience of quarantine has been an undesirable condition for people and it can have a negative impact on mental health and psychological wellbeing. Social isolation has led to an increase in time spent on social network sites, with people interacting more frequently with each other, and comparing online the way in which they are experiencing the same state of home confinement. Our study aimed to investigate the role of online social comparison on individuals' psychological distress and life satisfaction during the COVID-19-related quarantine. Specifically, a cross-lagged panel study at three-waves was conducted in Italy in order to examine the chan…

Can fiscal policy stimulus boost economic recovery

2011

We assess the role played by fiscal policy in explaining the dynamics of asset markets. Using a panel of ten industrialized countries, we show that a positive fiscal shock has a negative impact in both stock and housing prices. However, while stock prices immediately adjust to the shock and the effect of fiscal policy is temporary, housing prices gradually and persistently fall. Consequently, the attempts of fiscal policy to mitigate stock price developments (e.g. via taxes on capital gains) may severely de-stabilize housing markets. The empirical findings also point to significant fiscal multiplier effects in the context of severe housing busts, which gives rise to the importance of the im…

Familiarity and liking playing a role on the perception of trained panelists: A cross-cultural study on teas

2015

Consumers cultural background is known to influence their food choice. To better understand the sensory perception across cultures, it is helpful to work with both a descriptive panel and consumers. This study examined how tea products of differing fermentation levels were described and liked by different cultures. Seven tea samples were evaluated by Korean and French trained panels and consumers. The trained panels evaluated the samples on appearance, flavor, and mouthfeel. The consumers rated the samples on acceptability and familiarity. The result indicated that both descriptive panels experienced varying degrees of taste and odor cross-modal interaction. On the unfamiliar samples, Frenc…

Croissance et convergence des pays de la zone CFA : une étude par les données de panel non stationnaires

2011

During the recent years, african countries in the CFA zone have experienced many economic changes on the one hand through the measures initiated by bilateral and multilateral donors and on the other hand through the economic and monetary integration policies. Thus, relying on the assumption that because of these interventions, the economic systems incorporate various phenomena such as structural change and economic interdependencies, we studied their major implications on growth, convergence and growth predictability. Emphasis is first placed on the major features of integration policies in a monetary union, while stressing the possible implications of such policies on the economic dynamics…

Integrazione di celle fotovoltaiche ibride nel vetromattone

2012

L’invenzione riguarda l’integrazione del vetromattone con celle solari ibride (organiche/inorganiche), conosciute come Dye-sensitized Solar Cell (DSC). La combinazione del vetromattone con le DSC consente di migliorare le prestazioni del prodotto originario rendendolo in grado di produrre energia pulita. Le caratteristiche di trasparenza e isolamento termo-acustico del prodotto possono essere regolate agendo sulla configurazione delle DSC. Il prodotto può essere assemblato a formare pannelli fotovoltaici per la realizzazione di facciate traslucide energeticamente “attive” in varie condizioni luminose (condizioni di luce diffusa o artificiale) e indipendentemente dall’angolo di radiazione so…

The integration of Dye-sensitized Solar Cell (DSC) with the glassblock is disclosed. The combination of the two technological elements the glassblock and the DSC module enhance their own peculiarities. The final complete product is ready-made for installation owns the qualities of the glassblock and produces sustainable energy at the same time. The transparency and the thermo-acoustic insulation may be modulated according to the specific requirements of each case of installation. The product may be used for example to create PV panels for glazed and translucent façades that are able to perform efficiently in all light conditions (even in diffuse light also converting internal artificial light) that are not dependant on the angle of the solar radiation and do not suffer from the high operative temperatures of functioning due to the peculiarities of the DSCs. DSCs are made of economic and biocompatible materials and are produced with low-cost and highly productive printing methods on rigid or flexible substrates. With the integration of DSC modules with the glassblock PV panels coincide with the envelope itself so that they do not need any further structures to be installed on and allow the possibility of subtract from the price of the panel the price of the substituted building element allowing further economies. DSCs can be printed in different colours and with various patterns offering to designers and customers the possibility of intervening on the glassblock aesthetical aspect also taking advantage of the peculiar modularity of the glassblock for larger compositions of drawings on the building’s façade. Seven Hypotheses of integration are discussed in order to obtain DSC-integrated glassblock ready for the construction of a precast and dry-assembled PV panel which can use the horizontal and vertical cavities between the glassblocks to house plastic profiles where the electric interconnections and the steel bars -useful for improve the mechanical resistance of the panel- are integrated.Settore ICAR/10 - Architettura Tecnica
