    Large-scale slope failure involving Triassic and Middle Miocene salt and shale in the Gulf of Cádiz (Atlantic Iberian Margin) (2003)

    Notes: Sheets of salt and ductile shale advancing beyond the thrust front of the Gibraltar Arc (Iberian–Moroccan Atlantic continental margin) triggered downslope movements of huge allochthonous masses. These allochthons represent the Cádiz Nappe, which detached from the Gibraltar Arc along low-angle normal faults and migrated downslope from the Iberian and Moroccan continental margins towards the Atlantic Ocean. Extensional tectonics initiated upslope salt withdrawal and downslope diapirism during large-scale westward mass wasting from the shelf and upper slope. Low-angle salt and shale detachments bound by lateral ramps link extensional structures in the shelf to folding, thrusting and sheets of salt and shale in the Gulf of Cádiz. From backstripping analyses carried out on the depocentres of the growth-fault-related basins on the shelf, we infer two episodes of rapid subsidence related to extensional collapses; these were from Late Tortonian to Late Messinian (200–400 m Myr−1) and from Early Pliocene to Late Pliocene (100–150 m Myr−1). The extensional events that induced salt movements also affected basement deformation and were, probably, associated with the westward advance of frontal thrusts of the Gibraltar Arc as a result of the convergence between Africa and Eurasia. The complexities of salt and/or shale tectonics in the Gulf of Cádiz result from a combination of the deformations seen at convergent and passive continental margins.

    Notes: A 48-year-old man with a history of psoriasis, who had received no oral pharmacologic treatment, presented in March 2000 with a progressive, cutaneous, pruritic eruption that began on his arms and legs, and became generalized. Examination revealed discrete, purpuric elements disseminated over the entire cutaneous surface, and in some areas confluent, large, erythematous, purpuric patches (〈link href="#f3-1 #f3-2"〉Figs 1 and 2). The palmoplantar surfaces and mucous membranes were spared. No lesions suggesting parapsoriasis or the usual presentation of cutaneous T-cell lymphoma (CTCL) were present.〈figure xml:id="f3-1"〉1〈mediaResource alt="image" href="urn:x-wiley:00119059:IJD1774:IJD_1177_f3-1"/〉Confluent, large, erythematopurpuric patches with sharply pointed purpuric elements on the buttocks〈figure xml:id="f3-2"〉2〈mediaResource alt="image" href="urn:x-wiley:00119059:IJD1774:IJD_1177_f3-2"/〉Similar lesions on the lower limbsHistopathologic examination of a cutaneous specimen showed numerous atypical lymphocytes in the superficial dermis, slight changes at the dermo-epidermal junction, and an intense epidermotrophism, with atypical lymphocytes in the epidermis. These intraepidermal atypical lymphocytes were present both isolated and forming aggregates of 4-7 cells (〈link href="#f3-3"〉Fig. 3). Immunohistochemical studies demonstrated that these lymphocytes were T-helper cells.〈figure xml:id="f3-3"〉3〈mediaResource alt="image" href="urn:x-wiley:00119059:IJD1774:IJD_1177_f3-3"/〉Atypical lymphocytes in the superficial dermis, slight changes at the dermo-epidermal junction, and intense epidermotrophism, with atypical lymphocytes.

Direct examination of peripheral blood, coagulation, antinuclear antibody (ANA) immunofluorescent test, body scanner, and bone marrow study were normal.CTCL stage IB was diagnosed and psoralen plus UVA (PUVA) therapy was initiated.

    The regularity of solutions of reaction-diffusion equations via Lagrangian coordinates (1996)

    Notes: Abstract In this paper we study the regularity of nonnegative solutions and their interfaces for the nonlinear reaction-diffusion equation $$u_t = \left( {u^m } \right)_{xx} + f\left( u \right),\left( E \right)$$ wherem〉1 andf(u) is aC 1 function withf(0)=0 and is subject to some other technical conditions. This equation has the property of finite propagation which gives rise to interfaces separating regions whereu=0 andu〉0. The analysis is carried out by means of Lagrangian coordinates, formally viewing the reaction-diffusion equation as the equation governing the evolution of the density of a certain continuum. Lagrangian coordinates have been successfully applied to study nonlinear diffusion equations posed in one space dimension. The usual formulation applies to equations which can be written in the form of a conservation law, which is not the case here because of the reaction term. In problems exhibiting interfaces such technique has the merit of rendering the interfaces straight lines, much simplifying the analysis. In this paper we present anon-standard Lagrangian formulation that works innon-conservation cases. Equation (E) is then translated into this framework and we find in a natural way the necessary estimates to prove theC 1 regularity of moving interfaces and the regularity of the weak solution near such an interface, that allows us to establish the dynamic properties of the interface for the solutions. We end the paper by describing how the method can be applied to similar problems inseveral space dimensions with radial symmetry.

    Notes: Abstract During calcination of OCM catalyst precursors, Li...Cs spectacularly lower the amorphous silica → α-cristobalite phase transition temperature, shown here to be a critically important requirement for production of effective catalysts. Incorporation of W switches on OCM activity and newly discovered K/W and Rb/W formulations exhibit unsurpassed ethylene selectivity at high methane conversion. Addition of Mn significantly improves the performance of the former. An alkali-stabilised tungsten oxo species is thought to be the OCM active site.

    Necessary and sufficient conditions for complete blow-up and extinction for one-dimensional quasilinear heat equations (1995)

    Notes: Abstract We characterize the occurrence of complete or incomplete blow-up (and extinction) for a general quasilinear heat equation of the form $$(HE){\text{ }}u_t = (\phi (u))_{xx} \pm f(u){\text{ in }}R \times (0,T)$$ in terms of the constitutive functions φ and f We assume that φ′(u)〉0 for u〉0 and that f(u)≧0. For the positive sign + before f(u) in (HE), with f(u) superlinear as u→∞, blow-up occurs in finite time: sup x u(x, t)→∞ as t→T〈∞. For the negative sign, we consider the case of singular absorption: f(u)→∞ as u→0. Then initially positive solutions vanish at some point in finite time (extinction), and a singularity in the equation occurs there. An important aspect of blow-up or extinction problems is the possibility of having a nontrivial extension of the solution for t〉T, i.e., after the singularity occurs. If such continuation exists, we say that the blow-up (extinction) is incomplete; otherwise it is called complete. Our characterization is based on the qualitative behaviour of the family of travelling-wave solutions and a proper use of the Intersection-Comparison argument. The analysis applies to other nonlinear models, like the equations with gradient-dependent diffusivity.

    Regularity of Interfaces in Diffusion Processes under the Influence of Strong Absorption (1999)

    Notes: Abstract .We present a method of analysis which allows us to establish the interface equation and to prove Lipschitz continuity of interfaces and solutions which appear in a large class of nonlinear parabolic equations and conservation laws posed in one space dimension. Its main feature is intersection comparison with travelling waves. The method is explained on the following study case: We consider the Cauchy problem for the diffusion-absorption model: $$ u_t = \left( u^m \right)_{xx} - u^p, \quad u\ge 0, $$ in the range of parameters $m〉1,\ 0〈p〈1,\ m+p\ge2$, i.e., we have slow diffusion combined with strong absorption. Contrary to the case $p\ge 1$ , or the purely diffusive equation $u_t=(u^m)_{xx},\ m〉1$ , where the support of the solution expands with time and the motion is governed by Darcy's law, in the strong absorption range there might appear shrinking interfaces and the interface evolution obeys a different mechanism. Previous methods have failed to provide an adequate analysis of the interface motion and regularity in such a situation.

    Notes: Abstract We study the nonnegative solutions of the initial-value problem ut=(ur|ux|p-1ux)x,u(x, 0)∈L 1(ℝ), where p〉0, r+p〉0. The local velocity of propagation of the solutions is identified as V = -vx| vx|p-1 where v =cuα (with r +p - 1)/p and c (r +p/(r +p- 1)) is the nonlinear potential. Our main result is the a priori estimate (vx|vx|p-1)x≥- $$\frac{1}{{(2p + r) t}}$$ which we use to establish: i) existence and uniqueness of a solution of (1), ii) regularity of the free boundaries that appear when r+p〉1, and iii) asymptotic behavior of solutions and free boundaries for initial data with compact support.
