La interpretación jurídica con perspectiva de género : Un decálogo de estándares interpretativos
2021
: The Argentine legal system is part of the constitutional paradigm. In this case, the gender perspective is an essential condition to make a legal correct interpretation because its postulates influence any notion and course of legal action. On this matter, I assume a theoretical foundation of the gender theory and I recommend a decalogue of interpretative standards which receive its vision.
Effect of high temperature annealing (T > 1650 °C) on the morphological and electrical properties of p-type implanted 4H-SiC layers
2019
This work reports on the effect of high temperature annealing on the electrical properties of p-type implanted 4H-SiC. Ion implantations of Aluminum (Al) at different energies (30-200 keV) were carried out to achieve 300 nm thick acceptor box profiles with a concentration of about 10(20) at/cm(3). The implanted samples were annealed at high temperatures (1675-1825 degrees C). Morphological analyses of the annealed samples revealed only a slight increase of the surface roughness RMS up to 1775 degrees C, while this increase becomes more significant at 1825 degrees C (RMS = 1.2 nm). Room temperature Hall measurements resulted in a hole concentration in the range 0.65-1.34 x 10(18)/cm(3) and m…
Concepts for medium-high to high temperature thermoelectric heat-to-electricity conversion: a review of selected materials and basic considerations o…
2015
Within the last decade, novel materials concepts and nanotechnology have resulted in a great increase of the conversion efficiency of thermoelectric materials. Despite this, a mass market for thermoelectric heat-to-electricity conversion is yet to be opened up. One reason for this is that the transfer of the lab records into fabrication techniques which enable thermoelectric generator modules is very challenging. By closing the gap between record lab values and modules, broad industrial applications may become feasible. In this review, we compare three classes of materials, all designed for medium-high to high temperature applications in the field of waste heat recovery: skutterudites, half…

En torno a la casa de Medinaceli en el País Valenciano. El régimen enfitéutico en Segorbe, 1550-1737
1995
Este estudio sobre la distribución, usos del suelo y evolución del dominio útil constituye una primera aproximación a la caracterización de la compleja estructura de la propiedad segorbina. Aunque no se conoce el alcance de las posesiones francas o alodiales sitas en su término, los establecimientos efectuados desde 1612 de los bienes que habían pertenecido a los moriscos (en calidad de dominio útil) consolidaron el régimen enfitéutico en Segorbe. De todos modos, las conclusiones obtenidas han de ser tomadas con cautela; entre ellas destacarían las siguientes: que si bien figuraba todavía en 1737 un colectivo importante de enfiteutas con unas superficies medias que posiblemente les asegurar…
Identification of a novel mutation in the alpha-galactosidase A gene in patients with Fabry disease.
2012
Abstract Objectives Mutation analysis of the alpha-galactosidase A (GLA) gene is a valuable tool for the diagnosis of affected families. In our work, we analyze about one thousand samples per year from patients suspected of having Fabry disease (FD). Design and methods We carried out high resolution melting analysis (HRM) and DNA sequencing of all the exons of the GLA gene. We also assayed the alpha-galactosidase A activity in patients' blood. Results In some members of one family, we identified a new mutation in the GLA gene, c.614delC. This is a deletion of a single nucleotide, a cytosine, in exon 4 of the gene which causes a frameshift mutation. Conclusions Patients with the c.614delC mu…
Effect of Static Disorder in an Electron-Fabry Perot Interferometr with Two Quantum Scattering Centers
2007
In a recent paper -- F. Ciccarello \emph{et al.}, New J. Phys. \textbf{8}, 214 (2006) -- we have demonstrated that the electron transmission properties of a one-dimensional (1D) wire with two identical embedded spin-1/2 impurities can be significantly affected by entanglement between the spins of the scattering centers. Such effect is of particular interest in the control of transmission of quantum information in nanostructures and can be used as a detection scheme of maximally entangled states of two localized spins. In this letter, we relax the constraint that the two magnetic impurities are equal and investigate how the main results presented in the above paper are affected by a static d…
Angiokeratoma: decision-making aid for the diagnosis of Fabry disease
2012
Isolated angiokeratomas are common benign cutaneous lesions, generally deemed unworthy of further investigation. In contrast, diffuse angiokeratomas should alert the physician to a possible diagnosis of Fabry disease, a rare X-linked lysosomal storage disorder, characterized by a-galactosidase deficiency. Glycosphingolipids accumulate in cells throughout the body resulting in progressive multi-organ failure. Difficulties are encountered when trying to interpret the significance of angiokeratomas because they may also occur in other lysosomal storage disorders and rarely in an isolated manner in Fabry disease. We present an algorithm for the classification of angiokeratomas which might prove…
The tools like evidences of metal working? : strike supports, abrasives and burnishers, sharpening tools and crushing tools
2013
Lots of lithic tools are present in Metal Ages, but few are studied. In metal production, they are especially constitued by strike supports, abrasives, burnishers, sharpening tools and crushing tools. A part of them are in metal ( strike supports) or in ceramic (abrasives, sharpening tools). Contemporary forms of these tools are too different to permit a dierct comparison. It is necessary to work on the function of the tools, deduced from the analysis of these structure. Strike supports used for metal working are easily identifiable. They allow to reproduce more or less precisely the objects that they were fabricated with. Abrasives are difficult to relate to a material, but the traces of u…
The politics and process of abridgment
2011
Este trabajo examina el arriesgado proceso de la adaptación y, en particular, el de la edición abreviada de las obras canónicas de la literatura para público infantil; utilizo mis propios esfuerzos para adaptar Los viajes de Gulliver como punto de partida para este análisis. En última instancia, la historia de Gulliver, como cualquier cuento canónico, va más allá de un texto fijado, pues existe en gran medida a través de la memoria y de la oralidad, un proceso colectivo que, en vez de fijar la historia, la libera, asegurando tanto su fluidez como su estabilidad mediante la adaptación y la readaptación. El proceso de reescribir Los viajes de Gulliver se convierte, de esta manera, en problemá…
