Tratamiento del síndrome de sufrimiento del mediano en el tunel carpiano

En 3 de los 8 casos se llevó a cabo la intervención quirúrgica: la carnicera, una costurera y el lechero acromegálico (en ambos dedos). Exponemos con detalle la técnica empleada. Los resultados fueron buenos, precoces y brillantes sobre las parestesias, más tardíos y moderados, pero evidentes, sobre las atrofias

Translating and validating scale positive and negative experiences in Spanish adolescents

The objective of this study was to adapt and validate the scale of positive and negative experiences (SPANE) with Spanish adolescents, and to evaluate its relation with different scales of Subjective Well-being. SPANE is a recently developed questionnaire about affective well-being that can be considered an alternative to the instruments commonly used to evaluate positive/negative affects. The transcultural adaption process included translation and back translation stages, a panel of judges evaluating translations, and running a pilot test before obtaining a final version. The sample was formed by adolescents recruited for the study (N=1,060, Mean age=16.23 yrs). The adolescent’s version of this questionnaire showed good reliability, validity and internal consistency. It is an easy instrument to understand and is quick to complete, so it is considered useful for evaluating positive and negative experiences. The exploratory factorial analysis (EFA) clearly showed that both SPANE-P and SPANE-N presented 56.8% of accumulated variance (SPANE-P explained 31.30%, SPANE-N accounted for 24.88% of this variance for well-being), and both were capable of explaining the unique variance for well-being. These results evidence SPANE’s validity with adolescents, and support its use as a measuring instrument to evaluate experiences and predict well-being

Strain smoothing for compressible and nearly-incompressible finite elasticity

We present a robust and efficient form of the smoothed finite element method (S-FEM) to simulate hyperelastic bodies with compressible and nearly-incompressible neo-Hookean behaviour. The resulting method is stable, free from volumetric locking and robust on highly distorted meshes. To ensure inf-sup stability of our method we add a cubic bubble function to each element. The weak form for the smoothed hyperelastic problem is derived analogously to that of smoothed linear elastic problem. Smoothed strains and smoothed deformation gradients are evaluated on sub-domains selected by either edge information (edge-based S-FEM, ES-FEM) or nodal information (node-based S-FEM, NS-FEM). Numerical examples are shown that demonstrate the efficiency and reliability of the proposed approach in the nearly-incompressible limit and on highly distorted meshes. We conclude that, strain smoothing is at least as accurate and stable, as the MINI element, for an equivalent problem size

Coupled-Channel Theory of Photoionization Microscopy

We develop a quantum-mechanical coupled-channel theory to simulate spatial distributions of electron current densities, produced in photoionization for nonhydrogenic atoms in the presence of a uniform external electric field. The coupled Schrodinger equations are numerically solved using the renormalized Numerov method. The expression for the outgoing wave function for photoelectrons ejected from the nonhydrogenic atomic source is derived. The theory is applied to investigations of photoionization for ground-state Li atoms. The distributions of electron current densities are computed and compared to the corresponding experimental images. Excellent agreement is obtained. It is, furthermore, found that the presence of the nonhydrogenic residual ion significantly changes the differential cross sections and/or electron current densities with respect to the hydrogenic case. Finally, the implications of the presence of the atomic core for quantum resonance tunneling are also analyzed
