Abstract: A new cyprinid species is described based on morfometric, meristic and genetic characters. The new species identified, Yuriria amatlana sp. nov., inhabits the high Ameca Basin in the central plateau of Mexico. This Mexican minnow differs from Yuriria alta and Yuriria chapalae in terms of the following characters: (50-52) 53-54 pored lateralline scales; 10 upper transverse-line scales, 5-6 lower transverse-line scales and 8-10 gill rakers. Body coloration is light yellowish-brown. Compared to Yuriria alta and Yuriria chapalae, the new species has a less conspicuous dark grey band running from the start of the dorsal fin to the head. Cytochrome b gene sequences differ from those of Yuriria alta and Yuriria chapalae in terms of 29 fixed nucleotide positions (molecular autopomorphies). Calculated genetic divergences for the cytochrome b gene were: `DHKY = 3.8 (3.2-4.4%) between Yuriria amatlana sp. nov. and Y. alta; `DHKY = 5 (4.8-5.2%) between Y. amatlana sp. nov and Y. chapalae; and `DHKY = 2.6 (2.1-3.3%) between Y. chapalae and Y. alta. Se describe una nueva especie, Yuriria amatlana sp. nov., en base a caracteres morfométricos, merísticos y genéticos. La nueva especie proviene de la parte alta de la cuenca del río Ameca en la Meseta Central de México. Esta especie se diferencia de Yuriria alta y Yuriria chapalae por una combinación de los siguientes caracteres: (50-52) 53-54 escamas en una serie longitudinal, 10 escamas en una serie transversal por encima de la línea lateral y 5-6 escamas por debajo de la línea lateral y 8-10 branquiespinas. El color del cuerpo es amarillo-marrón claro. La nueva especie tiene una banda gris oscura menos marcada en el cuerpo desde el comienzo de la aleta dorsal hacia la cabeza con respecto a Yuriria alta y Yuriria chapalae. La nueva especie se diferencia de Yuriria alta y Yuriria chapalae en 29 posiciones nucleotídicas fijadas (autopomorfias moleculares) para el citocromo b. La divergencia genética entre Yuriria alta y Yuriria amatlana sp. nov. para el citocromo b fue de `DHKY = 3.8 (3.2-4.4%); entre Y. amatlana sp. nov. y Y. chapalae fue `DHKY = 5 (4.8-5.2%) y entre Y. chapalae y Y. alta fue `DHKY = 2.6 (2.1-3.3%).

Abstract: Objetivo/Método: Varón que presenta absceso y endoftalmitis por flora mixta (Estafilococo Aureus y Cándida Albicans) al mes del transplante de córnea. Resultados: Se realizan dos aspiraciones de humor acuoso y vítreo con administración intravítrea de Vancomicina y Anfotericina B. Tras estar asintomático 1 mes, recurre el absceso y se trata con Vancomicina y Ciprofloxacino intravenosos. A los 15 días de retirar el tratamiento, se reactiva la endoftalmitis que tratamos con antibióticos y antifúngicos intravenosos e intravítreos y vitrectomía, recuperando la visión. Conclusiones: La vitrectomía retardada fue necesaria para la eliminación de gérmenes acantonados y la desaparición de los brotes recurrentes.

New Insight on the Increasing Seismicity during Tenerife's 2004 Volcanic Reactivation
I. Domínguez Cerde?a,C. del Fresno,L. Rivera
Physics , 2012, DOI: 10.1016/j.jvolgeores.2011.06.005
Abstract: Starting in April 2004, unusual seismic activity was observed in the interior of the island of Tenerife (Canary Islands, Spain) with much evidence pointing to a reawakening of volcanic activity. This seismicity is now analyzed with techniques unprecedented in previous studies of this crisis. The 200 earthquakes located onshore during 2004 and 2005 have been classified by cross-correlation, resulting in a small number of significant families. The application of a relative location algorithm (hypoDD) revealed important features about the spatial distribution of the earthquakes. The seismic catalogue has been enhanced with more than 800 additional events, detected only by the closest seismic station. These events were assigned to families by correlation and as a consequence their hypocentral location and magnitude were estimated by comparing them to the earthquakes of each family. The new catalogue obtained by these methods identifies two major seismogenic zones, one to the northwest and the other to the southwest of the Teide-Pico Viejo complex and having a separation of at least 10 km between them. These regions alternate their activity starting in January 2004, i.e., three months earlier than previously thought. We propose a simple model based on the results of this work which will also concur with all previous geophysical and geochemical studies of the 2004 crisis. The model proposes a single magma intrusion affecting the central part of the island with lateral dikes driven by the rifts to the northwest and southwest.
Planck Scale Induced Speed of Sound in a Trapped Bose-Einstein Condensate

Physics , 2013, DOI: 10.1209/0295-5075/106/60005
Abstract: In the present work, we analyze the corrections caused by an anomalous dispersion relation, suggested in several quantum gravity models, upon the speed of sound in a weakly interacting Bose--Einstein Condensate, trapped in a potential of the form $V(r)\sim r^{2}$. We show that the corresponding ground state energy and consequently, the associated speed of sound, present corrections respect to the usual case, which may be used to explore the sensitivity to Planck--scale effects on these relevant properties associated with the condensate. Indeed, we stress that this type of macroscopic bodies may be more sensitive, under certain conditions, to Planck--scale manifestations than its constituents. In addition, we prove that the inclusion of a trapping potential, together with many--body contributions, improves the sensitivity to Planck--scale signals, compared to the homogeneous system.

Abstract: Introduction: According to the World Health Organization, malocclusion ia a higly risky entity that is placed in the 3rd position worldwide within oral diseases. There is a great relation among dento-maxillofacial disorders, dental vestibulo version, open bite and speaking disorders. Occlusion disorders can be more or less severe and can involve almost all the structures of the oral cavity. Objective: To check the usefulness of the modified Hawley′s device in patients with dental malocclusion produced by deforming habits and carriers of dyslalia. Method: Observational, analytico-comparative study carried out at the elementary school ¨Guerrillero Heroico¨ from Cienfuegos Municipality . A non-probabilistic sample of 32 patients was taken for this study; patients to whom 2 measurements were made. The variables under study were: Number of the Clinical record, Files, Dentomaxilofacial anomalies, sucking of the thomb, atypical deglussion, analysis of the pronunciation and levels of articulation. Hawley′s device was placed with an oval perforation at the level of the palatal folds changing the traditional form of the device. Result: There is a prevalence of malocclusion Class I. The most common maxillofacial disorders are: vestibulo version (87,5%), increased enhancement (84,4 %) and abnormal bilabial closure (68,8 %). Dyslalias were reduced during treatment from 81,2 % to 28,1 % at the end of treatment. Fundamento : La maloclusión es, según la OMS, una entidad que ocupa el tercer lugar entre las enfermedades estomatológicas que constituyen riesgo para la salud. Existe una gran relación entre las anomalías dentomaxilofaciales, api amiento, vestíbulo versión, mordida abierta, y los trastornos del habla. Las alteraciones de la oclusión pueden ser de mayor o menor gravedad y comprometer casi todas las estructuras de la cavidad oral. Objetivo : Comprobar la utilidad del aparato de Hawley modificado en pacientes con maloclusiones dentarias producidas por hábitos deformantes y portadores de dislalias. Métodos : Estudio observacional, analítico, comparativo, realizado en la escuela primaria ¨Guerrillero Heroico¨ del municipio de Cienfuegos. Se tomó una muestra no probabilística de 32 pacientes a los cuales se les realizaron dos mediciones. Se estudiaron las siguientes variables: Número de historia clínica, expediente, anomalías dentomaxilofaciales, hábitos como succión digital, deglusión atípica, análisis de la pronunciación y niveles de articulación. Se colocó Hawley con perforación en forma ovalada, a nivel de las rugosidades palatinas, lo que cambia la forma tradi

Abstract: RESUMEN El objetivo de este estudio es determinar la trascendencia que tienen en el juego de balonmano las transformaciones del sistema de ataque y las consecuencias que pueden extraerse para el entrenamiento. Para ello se ha utilizado como muestra a los cuatro primeros equipos de la liga ASOBAL en la temporada 2001-2002, analizándose todos los enfrentamientos entre estos cuatro equipos (24 partidos). Los resultados muestran que el juego con transformación del sistema de ataque inicial alcanza al 24,06% del tiempo de ataque en puestos específicos. El P. San Antonio logró una mayor eficacia en el juego con transformaciones que en el juego posicional (p =,003). Del mismo modo se identificó que el P. San Antonio es más eficaz en el juego con transformaciones que el F.C. Barcelona (p = ,046) En cuanto al perfil del juego de ataque con y sin transformaciones se identificaron tiempos más reducidos en la consecución de la eficacia jugando mediante transformaciones (entre 3 y 6 seg.) que sin ellas. Respecto a la distancia de finalización se encontraron igualmente diferencias significativas para el juego con transformación en su comparación con el juego sin transformación desde la distancia de más de 9 m. (p = ,0003) PALABRAS CLAVE: balonmano, transformación del sistema de ataque, eficacia ABSTRACT The objective of this study is to determine the transcendency that they have in the handball game the transformations of the attack system and the consequences that can be extracted for the training. For it has been used it as sample to the first four teams of the league ASOBAL in the season 2001-2002, being analyzed all the confrontations among these four teams (24 games). The results show that the game with transformation of the system of attack initial reaches to 24,06% of the time of attack in specific positions. The P. San Antonio achieved a bigger effectiveness in the game with transformations that in the game without transformations (p = ,003). In the same way it was identified that the P. San Antonio is more effective in the game with transformations that the F.C. Barcelona (p = ,046) as for the profile of the attack game with and without transformations more reduced times they were identified in the attainment of the effectiveness playing by means of transformations (between 3 and 6 seconds) that without them. Regarding the distance they met significant differences equally for the game with transformation in their comparison with the game without transformation from the distance of more than 9 m.

Abstract: La separación entre propiedad y gestión, junto con la presencia de accionistas minoritarios ha provocado la necesidad de mecanismos de control que permitan la aproximación de los objetivos de accionistas y directivos. Dentro de estos mecanismos destacan la divulgación de información a accionistas y el gobierno corporativo. El presente trabajo analiza la tipología de dicho vínculo para las sociedades mercantiles espa olas no-financieras que cotizan en un mercado organizado. Los resultados obtenidos, en contra de los esfuerzos actuales dirigidos a perfeccionar ambos mecanismos, ponen de manifiesto una relación sustitutiva, es decir, la divulgación de menores volúmenes de información para las compa ías cuyos consejos de Administración son más eficaces.
