Contributo al dimensionamento di una briglia a fessura con profilo lineare doppio

2011

L’obiettivo della sistemazione idraulica del tratto montano di un corso d’acqua e assicurare una condizione di stabilita per il cavo fluviale, mediante il raggiungimento di una condizione di equilibrio permanente tra la portata solida e quella liquida (Benini, 1984), facendo ricorso ad interventi di tipo strutturale capaci, nel rispetto della vigente normativa in tema di tutela  ambientale, di conservare e preservare gli ecosistemi preesistenti a valle (Ferro, 2006, 2008).

Paramedia : thresholds of the social text

2017

This work is an adaptation of Gerard Genette’s theory of paratexts to social media. Paratexts are information surrounding texts, and usually helping the user to decide whether or not to consume a text. In social media, a plurality of new information surrounds texts we read every day. They are dynamic by nature and have different authors: the social platforms, like Facebook or YouTube; the authors of texts, and the users who comment and share them. This collection of four articles will debate the ethos in social media, what is an author in social media, what are the identified paratexts in selected social media websites and the limits of interpretation of paratexts in contemporary Brazilian …

Collaborative Design Rational and Social Creativity in Cultures of Participation

2011

The rise in social computing has facilitated a shift from consumer cultures, focused on producing finished media to be consumed passively, to cultures of participation, where people can access the means to participate actively in personally meaningful problems. These developments represent unique and fundamental opportunities and challenges for rethinking and reinventing design rationale and creativity, as people acclimate to taking part in computer-mediated conversations of issues and their solutions. Grounded in our long-term research exploring these topics, this paper articulates arguments, describes and discusses conceptual frameworks and system developments (in the context of three cas…

Relazioni tra stiffness aortica ed indice di resistenza intrarenale nell’ipertensione arteriosa

2012

Per molti anni lo studio mediante eco-color-doppler dei parametri semiquantitativi emodinamici renali è stato utilizzato per rilevare le alterazioni della perfusione del rene trapiantato, per la diagnosi della stenosi dell’arteria renale o per valutare la progressione di alcune nefropatie. Più recentemente è stato osservato che tali parametri, ed in particolare l’indice di resistenza intrarenale (IR), non sono soltanto espressione della perfusione parenchimale, ma sono associati anche ad alterazioni morfo-funzionali sistemiche dell’albero vascolare. Vari studi hanno dimostrato come la stiffness aortica vada aumentando con il progressivo deterioramento della funzione renale. Tuttavia, dati c…

La nuisibilité directe des adventices en grandes cultures : quelles réponses nous apportent les essais désherbages ?

The direct harmful effect of weeds in field crops : what do herbicide trials tell us ? Weeds are plants whose undesirable qualities (“harmfulness") outweigh their desirable qualities (trophic resources). Few studies conclude that weeds do not affect crop yield. However, it is difficult to generalize since weeds compete with crops for resources and these resources are spatially and temporally variable. This study analyzed 110 herbicide trials (untreated vs. treated plots) performed in France from 1993 to 2015 on three major grain crops: winter wheat, winter oilseed rape and sunflower. Significant yield losses were found in 92% of wheat trials (average over all trials: -2.6 t/ha), 51% of wint…

Association between resting blood pressure and maximal blood pressure response to exercise and arterial health

2022

We investigated the longitudinal associations of blood pressure, cardiorespiratory fitness, and arterial stiffness among children. Arterial stiffening has been repeatedly shown to be a cardiovascular mortality predictor and can be observed early in childhood. As such, it is crucial to understand whether a child’s blood pressure, fitness level, and body composition can predict early signs of atherosclerosis and arterial stiffening. The current study examined the relationship between blood pressure, cardiorespiratory fitness, and arterial stiffness over time in children, using data from the Physical and Nutrition in Children (PANIC) Study. It is a physical and dietary intervention study condu…
