Effect of surface finish on the mechanical behaviour of Dacron© 360 woven
2013
Abstract In the present paper some experimental analyses of Dacron© 360 woven with and without surface treatment are presented to evaluate the effect of this treatment on the constitutive behaviour. This woven, widely adopted in sail manufacturing, is obtained by weaving polyethylene terephthalate (PET) yarn and it shows some peculiar features due to the manufacturing process. The experimental tensile tests, clearly show the orthotropy behaviour of the material. The effect of the treatment results in a stiffer behaviour especially along the warp and bias direction and in an increment of ultimate strength in all directions.
Restraining approach for the spurious kinematic modes in hybrid equilibrium element
2013
The present paper proposes a rigorous approach for the elimination of spurious kinematic modes in hybrid equilibrium elements, for three well known mesh patches. The approach is based on the identification of the dependent equations in the set of inter-element and boundary equilibrium equations of the sides involved in the spurious kinematic mode. Then the kinematic variables related to the dependent equations are reciprocally constrained and, by application of master slave elimination method, the set of inter-element equilibrium equations is reduced to full rank. The elastic solutions produced by means of the proposed approach verify the homogeneous, the inter-element and the boundary equi…
Il metodo e la storia
2006
The present volume aims to examine the relationship between some models of articulation of the system of art theory and the methodological reflection on the history of aesthetics in 20th-cen- tury Germany. Starting from Erwin Panofsky, this volume analyz- es various aspects of the debate of the 1920s and 1930s (the de- velopment of neo-Kantian methodology, historical phenomenolo- gy, and the beginning of the “history of ideas”), up to the great crisis caused by the rise of Nazism. The author discusses Panofsky’s theoretical essays from 1915 to 1932 and his renowned book Idea; Baeumler’s works on aesthetic historiography and his revision of Panofsky’s historiographic mo- del; Rothacker’s con…
Omologia e analogia
2016
Il numero mira a comprendere la polarità omologia/analogia, e a esplorarne gli usi nei diversi ambi- ti in cui essa ricorre nel dibattito contemporaneo in filosofia, nelle scienze della vita e nelle arti. La storia di questa coppia concettuale mostra la capacità pervasiva di costruire relazioni tra i diversi oggetti della conoscenza e, cosa ancor più interessante, la possibilità di raggiungere una sintesi concettuale fra approcci metodologici differenti. Il concetto di analogia stabilisce una relazione di somiglianza tra differenti caratteri in base a una considerazione funzionale degli organismi, mentre il concetto di omologia vede piuttosto l’identità sistemica fra i caratteri: l’omologia…

The citizens’ feedback on the EU management of the migration crisis
2017
The view of European citizens about the response of the EU to the immigration crisis is assessed in this paper by delving into Euro Barometer survey data. In the first sections, the analysis is framed by discussing the nature and causes of the present, mostly forced, migration flows, and the reasons why many Europeans want to keep the migrants out, despite the documented need of foreign workers. The remaining sections scan a set of Euro Barometer data to highlight the citizens’ concern with the migration issue and their reaction to the crisis management developed by the EU leaders in the past six years. The opinion of the citizens appears to be influenced by the convoluted negotiation of th…

Itália: esquerda convertida à defesa do capital sofre derrota histórica para ultra-direita
2001
Itália. Abril de 1996. Aquele que fora o maior partido comunista do Ocidente vence as eleições italianas. O Partido da Refundação Comunista, nascido quando o PCI mudara de nome – Partido dos Democratas de Esquerda, PDS –, assumindo-se social-democrata, apoiara, de fora, a coligação. A vitória era completa, ao fim de seis meses de governo de Berlusconi, desorganizado por greves contra as privatizações, cortes sociais etc. Romano Prodi, em menos de dois anos, saneou as finanças, dobrou a inflação, relançou as exportações. Para realizar o milagre, comprimiu salários, cortou investimentos, privatizou bens públicos, causou graves seqüelas sociais. O governo de centro-esquerda dependia do apoio d…
Modelling of phase transitions and residual thermal stress of CTBN rubber modified epoxy resins during a pultrusion process
2007
Abstract The implicit finite difference and fourth order Runge-Kutta method are used both to solve the heat transfer problem in the pultrusion reaction and to calculate the temperature and conversion distributions within a thermoset composite profile. The aim of our work is to study the influence of a rubbery phase added to the epoxy matrix in production conditions. The results have shown that the rubber modified systems have a low exothermic temperature peak value, so that neither the amount of cured resin nor the final product properties are limited. First of all we will show that the phase transition (gelation and vitrification) zones within the die change as the amount of rubber varies …
