Hommage à Goulven Madec Actes du colloque international organisé à Paris les 8 et 9 septembre 2011 Dans son étude d’Augustin, Goulven Madec n’a jamais dissocié le philosophe du prédicateur ; il s’est intéressé aux auteurs dont la lecture a été décisive pour Augustin, qu’il s’agisse de Cicéron ou de Porphyre, mais aussi à la réception de l’œuvre augustinienne. Les contributions rassemblées dans ce volume pour lui rendre homm..

Salt conservation, free surface, and varying levels: a new formulation for ocean general circulation models
No full textIn order to clarify the link between ocean salt content (OSC) conservation and the freshwater flux formulation in ocean general circulation models (OGCMs), a varying level thickness, nonlinear free surface version of the OPA is presented. Linear/nonlinear free surface equations are solved using an original approach based on an explicit damping of fast external gravity waves. The method leaves both the potential vorticity equation and the equilibrium state unchanged. Its numerics and cost are quite similar to those of implicit schemes. When nonlinearities are kept, a variable first level thickness is required. Its discretization is determined by volume and energy constraints. The OSC conservation depends on the surface kinematic equation used. Four formulations are presented: (1) virtual salt flux (fixed ocean volume and no volume flux), (2) natural (fixed ocean volume and volume flux), (3) linear free surface (fixed volume and volume flux computed from a linear free surface equation), and (4) assumption free (variable volume computed from a nonlinear free surface equation). Their impact is illustrated in 25 year low-resolution global OGCM simulations. In all cases the first-order ocean response is quite similar, as the concentration-dilution effect always exists. Formulations 4 and 2 ensure a strict conservation of the OSC. Nevertheless, the difference in formulation 3 is not strong enough to play a significant role: the conservation is almost perfect. Only formulation 1 neglects fresh water-driven surface pumping. This mainly modifies the sea surface salinity of the ocean basin where river runoffs are strong. No significant difference is found between the other formulations as a large time step dampens high-frequency free surface motion. The best compromise for climate is the linear free surface formulation. It allows a nearly exact OSC conservation, introduces the fresh water-driven pumping, and runs faster than all the other formulations
MADEC. Material Design Culture
No full textDue to the increased complexity of materials and production processes, the responsibility of the development of a design is often left in the hands of technicians and production personnel. This lack of knowledge about materials thus effectively creates a barrier between the designer and the product. Bridging this gap represents a challenge to designers and especially to the design schools. Designers cannot know everything but they can open their minds and develop a more conscious understanding of this new field of design practice starting from a cultural point of view. This paper wants to present a re-search promoted by the Design Department of Politecnico di Milano and funded by FARB (University Funds for Basic Re-search), for the creation of a Research Centre named MADEC, with the ambition of recognizing peculiarities of Italian Mate-rial Design Culture, and tracking their evolution in the contemporary era of “tailor made materials” as technological para-digma. The paper is divided into three parts: the first part concerns reasons, motivations and the state of the art of the research; the second part describes in detail the research activities developed during the first year of the project; and the third part is dedicated to conclusions with some critical considerations and future actions

MADEC: Exploring new methodologies to transfer material knowledge into design disciplines
No full textDue to the increased complexity of materials and production processes, the responsibility of
the development of a design is often left in the hands of technicians and production
personnel. This lack of knowledge about materials thus effectively creates a barrier between
the designer and the product. Bridging this gap represents a challenge to designers and
especially to the design schools. (Bak-Andersen 2013, p.69) Designers cannot know
everything but they can open their minds and develop a more conscious understanding of
this new field of design practice starting from a cultural point of view.
MADEC is a research group based in the Design Department of Politecnico di Milano in
2014 with the initial support provided by FARB founding (Fondi di Ateneo per la Riceca di
Base), which deals with the relation between design and materials in design history and
actuality. The center carries out researches on the “Italian Culture of Materials Design”,
intended as the capacity of the Italian design to “interpret” materials and technologies to
generate products and environments innovation.
The main goal of MADEC is to develop vocational students’ and apprentices’ design-related
competencies, integrating design into materials’ research and development, to better
support commercial and societal applications benefiting from a cultural and multidisciplinary
knowledge.
This paper will report in particular two significant experiences carried on during the first year
of MADEC: the e-journal issue “Italian Material Design: learning from history” and the open
lectures cycle “The Ideas and the Matter”.
The general project has been basically divided in four main activities: creating a open source
on-line platform and a research and co-design network; enhancing academic papers and
publications both concerning design history studies and contemporary topics; organizing
transdisciplinary symposiums, workshops and seminars; participating to European projects
seeking for collaboration between researches, designers and material suppliers and
manufacturers.
To the conclusion the paper will try to figure out the points of force and weakness of the
research project and to trace future guidelines to improve its research and educational
methodology

Family history of hypertension, anthropometric parameters and markers of early atherosclerosis in young healthy individuals
No full textThe predisposition to thrombogenesis is increased in essential hypertension, and hypertensive patients are prone to develop more vulnerable atherosclerotic plaques. To evaluate the possible influence of family history of hypertension on some indicators of early atherosclerosis, we studied eighty-five healthy normotensive individuals with (FH+) or without (FH-) family history of essential hypertension by measuring metabolic profile and concentrations of P-selectin, interleukin 6 and matrix metalloproteinase (MMP)-2, MMP-9, and tissue inhibitor of metalloproteinase (TIMP)-1. In a subset of individuals, MMP-9 activity was assessed in monocytes by zymography, and TIMP-1 expression by western blot. As compared with FH- individuals, FH+ individuals had significantly higher P-selectin but similar interleukin-6 levels. Although no difference was observed in MMP-2 levels between the two groups, MMP-9 and TIMP-1 were higher in FH+ individuals, who also had higher intracellular MMP-9 levels and TIMP-1 protein expression. P-selectin (r=-0.32; P<0.01), MMP-9 (r=-0.37; P<0.001) and TIMP-1 (r=-0.23; P<0.05) levels were inversely related to high density lipoprotein (HDL) cholesterol. P-selectin was also directly related to serum triglycerides (r=0.30; P<0.01). We conclude that a positive family history of hypertension is associated with an initial increase in markers of inflammation and plaque instability in otherwise healthy young normotensive individuals, likely conveying a predisposition to develop early atherothrombosis
