Attractors for a non-linear parabolic equation modelling suspension flows
No full textIn this paper we prove the existence of a global attractor with respect to the weak topology of a suitable Banach space for a parabolic scalar differential equation describing a non-Newtonian flow. More precisely, we study a model proposed by Hébraud and Lequeux for concentrated suspensionsou
Reminiscences of a radio astronomer
No full textInternational audienceThe author belongs to the second generation of radio astronomers. He started observing in 1954 with a German Riese-Würzburg radar transformed into a radio telescope, then in 1959-1963 with a two- Würzburg variable-spacing interferometer. He participated in the construction of the Nançay Large Radio Telescope, and used the Owens Valley Observatory interferometer during a stay in Caltech (1968-1969). He was deeply involved in the genesis of the French-German-Spanish Institute of Radio Astronomy at Millimeter waves (IRAM). His contacts with radio astronomers worldwide are described. In recent years, he participated in a series of seven papers devoted to the history of radio astronomy in France, published in this journal
P-31 Solid-State NMR Study of the Chemical Setting Process of a Dual-Paste Injectable Brushite Cements
No full textThe composition and evolution of a brushite-type calcium phosphate cement was investigated by Solid-State NMR and X-ray during the setting process. The cement is obtained by mixing beta-tricalcium phosphate [Ca-3(PO4)(2), beta-TCP] and monocalcium phosphate monohydrate [Ca(H2PO4)(2)center dot H2O, MCPM] in presence of water, with formation of dicalcium phosphate dihydrate or brushite [CaHPO2 center dot 2H(2)O, DCPD]. Analysis of the initial beta-TCP paste has shown the presence of beta-calcium pyrophosphate [Ca2P2O7, beta-CPy] and that of the initial MCPM a mixture of MCPM and dicalcium phosphate [CaHPO4, DCP]. Follow-up of the chemical composition by P-31 Solid-State NMR enables to show that the chemical setting process appeared to reach an end after 20 min. The constant composition observed at the end of the process was similarly determined. (C) 2009 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater 91 B: 46-54, 2009LT
Static and dynamic contact lines on a deformable coating of controled thickness
No full textInternational audienceFigure: From left to right: (a) drop on a soft substrate (water on PDMS), (b) structure near contact line, (c) non-linear simulations of the shear stress distribution below the contact line, whose intensity is encoded by the colours. Gel layers bound to a rigid substrate are used in cell culture to control differentiation and migration and to lower the friction and tailor the wetting of solids. Their thickness, often considered a negligible parameter, affects cell mechanosensing or the shape of sessile droplets [1]. We show first that the adjustment of thickness provides control over energy dissipation during the spreading of flowing matter on a gel layer [2]. We combine experiments and theory to uncover a scaling law that predicts the dynamic contact angle between the three phases as a function of the properties of the coating and the velocity of the contact line. We also demonstrate that thickness gradients can guide moving droplets. Our study shows that thickness is another parameter, besides surface energy and substrate mechanics, to tune liquid spreading and wetting on compliant coating, with potential applications to dew collection and free-surface film flow control. In a second step, we investigate numerically and theoretically the problem when the slope of the gel surface becomes non-negligible, the material reaching a regime of finite deformations, with non-linearities of geometrical origin. We show that both statics and dynamics are completely modified, a singular force displacing the well-known Neumann balance of forces at contact line [3]. We provide a general framework allowing to develop approximate analytical calculations, and give general laws governing the static and dynamic contact angle in this complex, non-linear regime. [1] J.

Birth, evolution and death of stars
No full textIt has been known for a long time that stars are similar to our Sun. But it was only in 1810 that they were shown to be made of an incandescent gas. The chemical composition of this gas began to be determined in 1860. In 1940, it was demonstrated that the energy radiated by the stars is of thermonuclear origin. How stars form from interstellar matter and how they evolve and die was understood only recently, with our knowledge still incomplete. It was also realized recently that close double stars present a wide variety of extraordinary phenomena, which are far from being completely explored. This book explains all these aspects, and also discusses how the evolution of stars determine that of galaxies. The most interesting observations are illustrated by spectacular images, while the theory is explained as simply as possible, without however avoiding some mathematical or physical developments when they are necessary for a good understanding of what happens in stars. Without being a textbook for specialists, this book can be profitably read by students or amateurs possessing some basic scientific knowledge, who would like to be initiated in-depth to the fascinating world of stars. The author, an emeritus astronomer of the Paris Observatory, worked in various domains of astronomy connected with the subject of this book: interstellar matter and evolution of stars and galaxies. He directed the Marseilles observatory from 1983 to 1988 and served for fifteen years as Chief Editor of the professional European journal Astronomy & Astrophysics. He has written many articles and books about physics and astronomy at different levels
