Cova dels Jurats at Calescoves (Alaior, Minorca). A Cave Shrine in the Talayotic context?

Excavations carried out in the Cova dels Jurats between 2010 and 2012 served to establish that, unlike the rest of the caves Calescoves, this one functioned as a sanctuary, with two different phases. The first one corresponds to the Final Talayotic Period, as the first cave shrine documented in the Talayotic culture. In Roman times, the place was still used as a sanctuary, but with a totally different ritual, linked to the inscriptions discovered at the entrance of the cave.

"Et occidetur virtute Domini Antichristus a Mikaele arcangelo". Paisaje y escatología en Sant Miquel de Llíria (s. XIV d. C.)

El presente articulo intenta determinar las razones por las que el santuario de Sant Miquel de Llíria, uno de los más importantes de la actual provincia de Valencia, se consagró al arcàngel guerrero. Se estudia para ello la historia de su culto en Occidente, haciendo hincapié en aspectos como su relación con los lugares elevados y la frecuente proximidad de sus santuarios con aquellos dedicados a la Virgen. Atenderemos también a aspectos fundamentales del contexto histórico, como los movimientos de renovación espiritual medievales, la influencia del médico y teólogo Arnau de Vilanova en la Valencia de principios del siglo XIV y las profecías escatológicas vinculadas a la llegada del Anticristo.

Effect of the Electrolyte Formulation on the Performances of Edlc and Li-Ion Batteries

One of the most important components in electrochemical storage devices (batteries and supercapacitors) is undoubtedly the electrolyte. The basic function of any electrolyte in these systems is the transport of ions between the positive and negative electrodes. In addition, electrochemical reactions occurring at each electrode/electrolyte interface are the origin of the current generated by storage devices. In other words, performances (capacity, power, efficiency and energy) of electrochemical storage devices are strongly related to the electrolyte properties, as well as, to the affinity for the electrolyte to selected electrode materials. Indeed, the formulation of electrolyte presenting good properties, such as high ionic conductivity and low viscosity, is then required to enhance the charge transfer reaction at electrode/electrolyte interface (e.g. charge accumulation in the case of Electrochemical Double Layer Capacitor, EDLC). For practical and safety considerations, the formulation of novel electrolytes presenting a low vapor pressure, a large liquid range temperature, a good thermal and chemical stabilities is also required.

This lecture will be focused on the effect of the electrolyte formulation on the performances of electrochemical storage devices (Li-ion batteries and supercapacitors). During which, a summary of the physical, thermal and electrochemical data obtained by our group, recently, on the formulation of novel electrolyte-based on the mixture of an ionic liquid (such as EmimNTf2 and Pyr14NTf2) and carbonate or dinitrile solvents will be presented and commented. The impact of the electrolyte formulation on the storage performances of EDLC and Li-ion batteries will be also discussed to further understand the relationship between electrolyte formulation and electrochemical performances. This talk will also be an opportunity to further discuss around the effects of additives (SEI builder: fluoroethylene carbonate and vinylene carbonate), ionic liquids, structure and nature of lithium salt (LiTFSI vs LiPF6) on the cyclability of negative electrode to then enhance the electrolyte formulation. For that, our recent results on TiSnSb and graphite negative electrodes will be presented and discussed, for example 1,2.

Radiative rates for E1, E2, M1, and M2 transitions in Br-like ions with 43≤Z≤50

Energies and lifetimes are reported for the eight Br-like ions with 43≤Z≤50, namely Tc IX, Ru X, Rh XI, Pd XII, Ag XIII, Cd XIV, In XV, and Sn XVI. Results are listed for the lowest 375 levels, which mostly belong to the 4s²4p⁵, 4s²4p⁴4ℓ, 4s4p⁶,4s²4p⁴5ℓ, 4s²4p³4d², 4s4p⁵4ℓ, and 4s4p⁵5ℓ configurations. Extensive configuration interaction among 39 configurations (generating 3990 levels) has been considered and the general-purpose relativistic atomic structure package (grasp) has been adopted for the calculations. Radiative rates are listed for all E1, E2, M1, and M2 transitions involving the lowest 375 levels. Previous experimental and theoretical energies are available for only a few levels of three, namely Ru X, Rh XI and Pd XII. Differences with the measured energies are up to 4% but the present results are an improvement (by up to 0.3 Ryd) in comparison to other recently reported theoretical data. Similarly for radiative rates and lifetimes, prior results are limited to those involving only 31 levels of the 4s²4p⁵, 4s²4p⁴4d, and 4s4p⁶ configurations for the last four ions. Moreover, there are generally no discrepancies with our results, although the larger calculations reported here differ by up to two orders of magnitude for a few transitions.

Sistema de seguridad social integral: Artículo 43. Constitución Política de Colombia, Ley 100 de 1993

Por fin en Colombia se ha puesto atención a una necesidad social que, aunque siempre ha existido, ha sido más sentida en el mundo actual: la seguridad social. Es un tema actual, ya que se hace necesario establecer normas que redunden en beneficio de toda la sociedad mundial y en particular de la nuestra, la colombiana; es preciso organizar las vidas de esta gran cantidad de seres humanos que habitan un espacio hasta ahora limitado: el mundo.

Symmetry reduction due to gallium substitution in the garnet Li6.43(2)Ga0.52(3)La2.67(4)Zr2O12

Single-crystal structure refinements on lithium lanthanum zirconate (LLZO; Li7La3Zr2O12) substituted with gallium were successfully carried out in the cubic symmetry space group I [Formula: see text]3d. Gallium was found on two lithium sites as well as on the lanthanum position. Due to the structural distortion of the resulting Li6.43(2)Ga0.52(3)La2.67(4)Zr2O12 (Ga-LLZO) single crystals, a reduction of the LLZO cubic garnet symmetry from Ia[Formula: see text] d to I [Formula: see text]3d was necessary, which could hardly be analysed from X-ray powder diffraction data.

Review: Head and neck squamous cell carcinoma in sub-Saharan Africa

Aim Review the literature from 1990 to 2013 to determine known anatomic sites, risk factors, treatments, and outcomes of head and neck squamous cell carcinoma (HNSCC) in sub-Saharan Africa. Methods Using a systematic search strategy, literature pertaining to HNSCC in sub-Saharan Africa was reviewed and patient demographics, anatomic sites, histology, stage, treatment, and outcomes were abstracted. The contributions of human immunodeficiency virus (HIV), human papillomavirus (HPV) and behavioural risk factors to HNSCC in the region were assessed. Results Of the 342 papers identified, 46 were utilized for review, including 8611 patients. In sub-Saharan Africa, the oropharyngeal/oral cavity was found to be the most common site, with 7750 cases (90% of all cases). Few papers distinguished oropharyngeal from oral cavity, making identification of possible HPV-associated oropharyngeal squamous cell carcinoma (SCC) difficult. SCC of the nasopharynx, nasal cavity, or paranasal sinuses was identified in 410 patients (4.8% of all cases). Laryngeal SCC was found in 385 patients (4.5% of all cases), and only 66 patients (0.8% of all cases) with hypopharyngeal SCC were identified. In 862 patients with data available, 43% used tobacco and 42% used alcohol, and reported use varied widely and was more common in laryngeal SCC than that of the oropharyngeal/oral cavity. Toombak and kola nut use was reported to be higher in patients with HNSCC. Several papers reported HIV-positive patients with HNSCC, but it was not possible to determine HNSCC prevalence in HIV-positive compared to negative patients. Reports of treatment and outcomes were rare. Conclusions The oropharyngeal/oral cavity was by far the most commonly reported site of HNSCC reported in sub-Saharan Africa. The roles of risk factors in HNSCC incidence in sub-Saharan Africa were difficult to delineate from the available studies, but a majority of patients did not use tobacco and alcohol.

La expansión del incidente de nulidad de actuaciones por motivos procesales. A propósito de la STC 43/2010, de 26 de julio

En este artículo el autor realiza un estudio detallado de la trascendental STC (1.ª) 43/2010, de 26 de julio, que marcó un hito en la interpretación que el Alto Tribunal realizó del art. 241 LOPJ, tras la reforma legislativa operada en el año 2007, a través de la LO 6/2007, de 24 de mayo. En esta sentencia se otorga el amparo porque un Juzgado de Primera Instancia había producido una clara indefensión a los recurrentes, consistente en la imposibilidad de éstos de conocer y comparecer en un proceso ejecutivo en el que resultaban afectados directamente sus intereses, pues se subastó y adjudicó una vivienda de su propiedad pese a haber sido advertido el Juzgado, por diferentes conductos, de que ellos eran los titulares registrales de dicho bien inmueble. La especial relevancia de la STC (1.ª) 43/2010, de 26 de julio —con claras concomitancias con la STC (2.ª) 40/2005, ya que ambas tienen su origen en actos procesales del mismo procedimiento judicial de ejecución, aunque los demandantes de amparo fueran distintos—, radica en resaltar el reforzado protagonismo, en aras de la defensa del derecho fundamental a la tutela judicial efectiva, que ha adquirido el incidente de nulidad de actuaciones, tras la reforma operada en el art. 241.1 LOPJ por la LO 6/2007, de 24 de mayo, por la que se modifica la Ley Orgánica 2/1979, de 3 de octubre, del Tribunal Constitucional. El TC cambia su postura y viene a afirmar, sin ambages, que el incidente de nulidad de actuaciones se ha erigido en el instrumento clave para la tutela del derecho fundamental a la tutela judicial efectiva sin indefensión, como última vía que permite la reparación ante la jurisdicción ordinaria, máxime si se tiene en cuenta el nuevo sistema, mucho más restrictivo, de admisión a trámite del recurso de amparo ante el TC (sólo si concurre una «especial trascendencia constitucional»).
