A critical assessment of methods for the determination of the shear stress amplitude in multiaxial fatigue criteria belonging to critical plane class

2015

Abstract Multiaxial high cycle fatigue criteria based on the critical plane approach necessitate unambiguous definitions of the amplitude and mean value of the shear stress (τa and τm) acting on the material planes. Four of the existing definitions relate the values of τa and τm to a geometrical element of the curve described by the tip of the shear stress vector (curve Ψ), respectively, the radius of the Minimum Circumscribed Circle, the Longest Chord, the Longest Projection, the diagonal of the Maximum Rectangular Hull (MRH). In this paper a critical assessment of the above definitions is proposed, focusing on that based on the concept of MRH, which is the most recently developed. The mai…

Ischemic cardiovascular disease in workers occupationally exposed to urban air pollution – A systematic review

2018

Introduction Cardiovascular disease is the first cause of morbidity and mortality worldwide. Among several known risk factors, researchers also focus their attention on the chronic exposure to air pollution. There is much evidence that exposure to air pollution, especially to ultrafine particles, can damage the endothelium and can favour cardiovascular diseases in the general population. Occupational exposition could be an additive risk factor for the cardiovascular system. This article presents a scientific review of the linkage between occupational exposure to air pollution and ischemic heart disease. Material and methods A scientific review was undertaken, followed by PRISMA Statements. …

Diagnostic algorithm for familial chylomicronemia syndrome

2016

International audience; Background: Familial chylomicronemia syndrome (FCS) is a rare genetic disease that leads to severe hypertriglyceridemia often associated with recurrent episodes of pancreatitis. The recognition and correct diagnosis of the disease is challenging due to its rarity, and to the lack of specificity of signs and symptoms. Lipid experts, endocrinologists, gastroenterologists, pancreatologists, and general practitioners may encounter patients who potentially have FCS. Therefore, cooperation between experts and improved knowledge of FCS is essential in improving the diagnosis. Currently, a consensus on best practice for the diagnosis of FCS is lacking. Methods: Aiming to def…

Qui e là. Le Letterature dimenticate: Indocina, Cina, Corea, Giappone, Turchia

2018

Esistono alcuni Paesi del Continente asiatico che, vuoi per ragioni storiche, vuoi per ragioni economiche o culturali continuano a mantenere l’uso della lingua francese come ufficiale, co-ufficiale o di semplice uso comune e, di conseguenza, esistono alcune realtà letterarie che sfuggono spesso all’attenzione della critica o che restano in ogni caso poco conosciute. I Paesi del Continente asiatico che continuano a mantenere un legame linguistico con la Francia sono: la penisola indocinese (con la Cambogia, il Laos e il Vietnam); la Cina, la Corea e il Giappone. A questi Paesi, benché geograficamente inclusa nel continente europeo, va aggiunta la Turchia che per ragioni storico-politico-econ…

La mia notte con Maud: un'analisi

2016

Per chi ama il cinema francese "La mia notte con Maud" di Eric Rohmer, terzo dei suoi "Racconti morali", è un piacere da vivere e condividere. Accanto al film c’è un’altra storia, quella di un testo al plurale: nato come novella nel 1944, sceneggiato in successive versioni, realizzato nel 1969 e riconsegnato alla sua forma narrativa nel 1974. Solo sullo schermo "Maud" trova la sua pienezza, senza però nascondere la nostalgia della scrittura. Una struttura perfetta, una trama che si apre ad altre trame, un film da vedere e rivedere in una notte da cui non vorremmo mai uscire.

Modelling the influence of nanoparticles in the phase behaviour of an epoxy/polystyrene mixture

2007

Abstract The cloud point temperatures of four series of epoxy/polystyrene blends have been experimentally determined as a function of polymer mass and system composition. The phase diagrams show an UCST behaviour, increasing incompatibility as the molar mass increases. The Flory–Huggins theory with a concentration-dependent interaction parameter has been developed to study the compatibility of two polymers in presence of spherical nanoparticles. This theory has been first compared with the experimental cloud point curve in absence of nanoparticles, and secondly it has been used to predict the thermodynamic behaviour in presence of different volume fraction of nanoparticles. Nanoparticles co…

Shear-Induced Crystallization and Shear-Induced Dissolution of Poly(ethylene oxide) in Mixtures with Tetrahydronaphthalene and Oligo(dimethyl siloxan…

2003

Cloud point temperatures (T cp ) and crystallization temperatures (T 1/s ) were measured at different constant shear rates for the ternary system tetrahydronaphthalene/poly(ethylene oxide)/oligo(dimethyl siloxane-b-ethylene oxide) using a rheo-optical device and in the case of T 1/s additionnaly a viscometer. This system enables for the first time a joint investigation of both transitions with a given mixture. Shear favors the homogeneous liquid state and the formation of crystals. T cp (liquid/liquid demixing, UCST) shifts to lower and T 1/s (liquid/solid, segregation of PEO) to higher temperatures by several degrees as the shear rate, γ, is increased up to 500 s -1 . The normalized shift …

Il nobile casato dei Ventimiglia e Donna Felice Ventimiglia Barberini

2017

Nella prima parte del saggio (R.F. Margiotta, Il nobile casato dei Ventimiglia dalla Liguria alla Sicilia) si delinea la storia dei Ventimiglia, provenienti dalla Liguria, insediatisi in Sicilia sin dal Duecento, da Francesco I a Francesco IV Rodrigo, padre di Felice Ventimiglia, e ci si sofferma sulle opere più rappresentative da loro commissionate. Nella seconda parte (M.C. Di Natale, Felice Ventimiglia Barberini dal principato di Castelbuono a Roma) si prende in esame la figura di donna Felice Ventimiglia e se ne ripercorrono le vicende della vita attraverso due significativi documenti: l'inventario dotale della nobildonna, stilato nel 1693, in occasione delle nozze con il principe di pa…
