OBJECTIVE The aim of this study was to evaluate the exercise tolerance by expired gas analysis during stress test in patients with Systemic Sclerosis (SSc). METHODS Eighteen women (mean age 48.56+/-12.48 years) affected by SSc were studied. A complete echocardiographic examination including pulmonary artery systolic pressure estimation, pulmonary function(More)
This paper addresses a three-dimensional model for isothermal stress-induced transformation in shape memory polycrystalline materials in presence of permanent inelastic effects. The basic features of the model are recalled and the constitutive and the three-dimensional quasi-static evolution problem are proved to be well-posed. Finally, we discuss the(More)
We prove regularity results for minimizers of functionals F(u, Ω) := Ω f (x, u, Du) dx in the class K := {u ∈ W 1,p(x) (Ω, R) : u ≥ ψ}, where ψ : Ω → R is a fixed function and f is quasiconvex and fulfills a growth condition of the type L −1 |z| p(x) ≤ f (x, ξ, z) ≤ L(1 + |z| p(x)), with growth exponent p : Ω → (1, ∞).
Copyright line will be provided by the publisher We prove C 0,α regularity for minimizers u of functionals with p(x)-growth of the type F(w, Ω) := Z Ω f (x, w(x), Dw(x)) dx, in the class K := {w ∈ W 1,p(x) (Ω; R) : w ≥ ψ}, where the exponent function p : Ω → (1, ∞) is assumed to be continuous with a modulus of continuity satisfying lim sup ρ→0 ω(ρ) log " 1(More)
For minimizers u ∈ W 1,p(x) (Ω) of quasiconvex integral functionals of the type F [u] := Ω f (x, Du(x)) dx with p(x) growth in the class K := {u ∈ W 1,p(x) (Ω) : u ≥ ψ}, where ψ ∈ W 1,p(x) (Ω) is a given obstacle function, we show estimates of Calderón-Zygmund type, i.e. |Dψ| p(·) ∈ L q =⇒ |Du| p(·) ∈ L q , for any q > 1, provided that the modulus of(More)
We consider a model system describing the two-dimensional flow of a conducting fluid surrounded by a ferromagnetic solid under the influence of the hysteretic response of the surrounding medium. We assume that this influence can be represented by the Preisach hysteresis operator. Existence and uniqueness of solutions for the resulting system of PDEs with(More)
After pointing out the need for reconstruction of the nipple-areola complex and the restoration of symmetry between the two breasts after radical mastectomy for cancer, the paper briefly examines the techniques currently available for the achievement of these "finishing touches" that usually take longer then the primary and fundamental breast reconstruction.
We address the thermal control of the quasi-static evolution of a polycrystalline shape memory alloy specimen. The thermomechanical evolution of the body is described by means of an extension of the phenomenological Souza-Auricchio model [6, 7, 8, 57] accounting also for permanent inelastic effects [9, 11, 27]. By assuming to be able to control the(More)
