Continuum of solutions for an elliptic problem with critical growth in the gradient

David Arcoya, Colette De Coster, Louis Jeanjean, Kazunaga Tanaka

We consider the boundary value problem(Pλ)u∈H01(Ω)∩L∞(Ω):-δu=λc(x)u+μ(x)|∇u|2+h(x), where Ω⊂RN, N≥3 is a bounded domain with smooth boundary. It is assumed that c{greater-than but not equal to}0, c, h belong to Lp(Ω) for some p>N/2 and that μ∈L∞(Ω). We explicitly describe a condition which...

Influence of sodium borate on the early age hydratation of calcium sulfoaluminate cement

Jean-Baptiste Champenois, Mélanie Dhoury, Céline Cau Dit Coumes, Cyrille Albert-Mercier, Bertrand Revel, Patrick Le Bescop, Denis Damidot

Calcium sulfoaluminate (CSA) cements are potential candidates for the conditioning of radioactive wastes with high sodium borate concentrations. This work thus investigates early age hydration of two CSA cements with different gypsum contents (0 to 20%) as a function of the mixing solution...

Influence of heat and ultrasonic treatments on the setting and maturation of a glass-ionomer cement

Marion Dehurtevent, Etienne Deveaux, Jean-Christophe Hornez, Lieven Robberecht, Nicolas Tabary, Feng Chai

Purpose: To compare the effect of different treatments (heat capsule, ultrasound, and dual treatments) on the setting kinetics and maturation properties of a conventional GIC (EQUIA, GC) to that of standard setting. Methods: The optimal durations of the heat and ultrasonic treatments were...

Nodal properties of eigenfunctions of a generalized buckling problem on balls

Colette De Coster, Serge Nicaise, Christophe Troestler

In this paper we are interested in the following fourth order eigenvalue problem coming from the buckling of thin films on liquid substrates: ∆^2 u + κ^2 u = −λ ∆ u in B_1 , u = ∂_r u = 0 on ∂ B_1 , where B_1 is the unit ball in R^N. When κ > 0 is small, we show that the first eigenvalue is...

Odontological information along cone splines

Cindy González, Marco Paluszny

Developable surfaces are a subset of ruled surfaces, which can be mapped onto a plane without deformation. Due to this property, they have considerable relevance in several applications. In the medical area, regarding information visualization along sections of organs, they could be useful in...

Effect of Nitrogen on Properties of Na 2 O-CaO-SrO-ZnO-SiO 2 Glasses

Ahmed Bachar, Cyrille Albert-Mercier, Arnaud Tricoteaux, Jean-Christophe Hornez, Anne Leriche, Claudine Follet-Houttemane, Bertrand Revel, Stuart Hampshire, Mark Towler

Glasses in the Na2O–CaO–SrO–ZnO–SiO2 system have previously been investigated for suitability as a reagent in Al-free glass polyalkenoate cements (GPCs). These materials have many properties that offer potential in orthopedics. However, their applicability has been limited, to date, because of...
