Il concorso esterno tra diritto e processo. Aspettando il coraggio del legislatore
2012
L'autore affronta la tormentata questione del concorso esterno all'indomani di importanti pronunzie di merito e di legittimità che hanno in qualche modo rimesso in discussione la legittimità dogmatica e la plausibilità politico criminale dell'istituto. Al termine di un'analisi dettagliata degli orientamenti giurisprudenziali, il saggio si conclude con l'auspicio di una rapida e coerente riforma legislativa
Desarrollo y evaluación psicométrica de una forma abreviada de la escala de posicionamiento ante el diagnóstico enfermero
2013
El Position on Nursing Diagnosis (PND) es una escala que utiliza la técnica del diferencial semántico para medir las actitudes hacia el concepto diagnóstico enfermero. El estudio objetivó desarrollar una forma abreviada de la versión española de esta escala, evaluar sus propiedades psicométricas y eficiencia. Se utilizó un doble enfoque empírico-teórico para obtener una forma reducida del PND, el PND-7-SV, que fuera equivalente a la original. Mediante un diseño transversal a través de encuesta, se evaluó la fiabilidad (consistencia interna y fiabilidad test-retest), validez de constructo (análisis factorial exploratorio, técnica de grupos conocidos y validez discriminante) y de criterio (va…
Suzuki polycondensation with a hairpin monomer.
2009
Two straight monomers were subjected to an AA/BB-type Suzuki polycondensation with a hairpin-shaped 1,8-anthrylene monomer as the counterpart leading to a novel polyarylene which should have the preferred conformation of a folded chain. The molar masses were determined by gel permeation chromatography and dynamic light scattering and found to be M(w) = 14,000 and M(n) = 7,000. MALDI-TOF MS analysis of a fraction provides a fingerprint of the step-growth nature of this polymerization.
Lattice-Boltzmann and finite difference simulations for the permeability of three-dimensional porous media
2002
Numerical micropermeametry is performed on three dimensional porous samples having a linear size of approximately 3 mm and a resolution of 7.5 $\mu$m. One of the samples is a microtomographic image of Fontainebleau sandstone. Two of the samples are stochastic reconstructions with the same porosity, specific surface area, and two-point correlation function as the Fontainebleau sample. The fourth sample is a physical model which mimics the processes of sedimentation, compaction and diagenesis of Fontainebleau sandstone. The permeabilities of these samples are determined by numerically solving at low Reynolds numbers the appropriate Stokes equations in the pore spaces of the samples. The physi…
The study of correlation between microstructure of ferrites and their complex permeability spectra
2013
Theoretical model for complex permeability of polycrystalline ferrite (based on effects arising from realities of typical microstructure of sample) is correlated with experimental data. In the case of NiZn-ferrites there is observed a close agreement with the model and the data; for samples of MnZn-ferrites this agreement is only for small-sized cores; for bigger ones the dimensional effects (dimensional resonance) appear and the model cease to be valid.

The dynamical region of the measured calibration curves is investigated using the results of the theory published previously. The kinetic constants of the flow-equilibrium are calculated from the measurements according to two different models for a spontaneous polymer diffusion of the transported P-mer from sol into gel of the Phase Distribution Chromatography (PDC)-column. The corresponding lateral concentration profiles in the gel are found by analytical integration of Fick's second law under the corresponding boundaries. An energetic model of this flow-equilibrium is stated, giving the activation enthalpy and -entropy of the rediffusion of the polymer from gel into sol after some retarda…
Magnetic Field and Short-Circuit Reactance Calculation of the 3-Phase Transformer with Symmetrical Amorphous Core
2006
Magnetically symmetric, 3- phase transformer has been analysed. For the two variants of the windings, the calculation results have been compared with the measured ones. Magnetic flux density components were calculated in and out of the core. The flux distribution and short-circuit reactance have been verified experimentally and a good agreement has been obtained.
Essential elements of professional nursing environments in Primary Care and their influence on the quality of care
2018
Objectives Nursing work environments (NWE) are key determinants of care quality. Our study aimed to evaluate the characteristics of nursing environments in primary care settings in the Canary Islands, and identify crucial components of such environments to improve quality. Method We conducted a cross-sectional study in primary care organisations using the Practice Environment Scale - Nursing Work Index (PES-NWI) tool. We collected sociodemographic variables, PES-NWI scores, and selected the essential items conducive to optimal care. Appropriate parametric and non-parametric statistical tests were used to analyse relations between variables (CI = 95%, error = 5%). Results 144 nurses particip…
Design of experiment approach applied to reducing and oxidizing tolerance of anode supported solid oxide fuel cell. Part I: Microstructure optimizati…
2011
The main drawback of Ni/YSZ anode supports for solid oxide fuel cell application is their low tolerance to reducing and oxidizing (RedOx) atmosphere changes, owing to the Ni/NiO volume variation. This work describes a structured approach based on design of experiments for optimizing the microstructure for RedOx stability enhancement. A full factorial hypercube design and the response surface methodology are applied with the variables and their variation range defined as: (1) NiO proportion (40-60 wt% of the ceramic powders), (2) pore-former proportion (0-30 wt% corresponding to 0-64 vol.%), (3) NiO particle size (0.5-8 mu m) and (4) 8YSZ particle size (0.6-9 mu m).
La disputa fronteriza entre India y China: origen y evolución de la controversia
2008
Con la emergencia de la India independiente y de la China maoísta a mediados del siglo pasado, los dos nuevos gobiernos de Delhi y Pekín comenzaron a convivir en un marco de armonía bajo los principios de coexistencia pacífica y una política de hermandad entre ambos pueblos, conocida como Hindi-Chini Bhai Bhai. Sin embargo, a pesar de estas actitudes amistosas iniciales, la herencia colonial británica en la India y las consecuencias de la anexión china del territorio tibetano, vinieron a desestabilizar este equilibrio, con el enfrentamiento de las pretensiones soberanistas de ambos Estados emergentes sobre distintas zonas fronterizas.El análisis del origen y la evolución de la controvertida…
