Cisneros' Cantorales: from Hispanic chant to Neo-Mozarab chant

Tesis de la Universidad Complutense de Madrid, Facultad de Geografía e Historia, Departamento de Musicología, leída el 10/04/2019La tesis doctoral titulada “Los Cantorales de Cisneros: del canto hispánico al canto neomozárabe” explora la restauración que el Cardenal Jiménez de Cisneros hizo a principios del siglo XVI del llamado canto hispánico, tratando de demostrar cómo se construyeron las melodías de los Cantorales de Cisneros. Tras la lectura de varios trabajos precedentes, se ha planteado una hipótesis alrededor de la cual gira toda esta investigación y que parte de la idea de que existe una conexión directa, demostrable objetivamente, entre el canto hispánico medieval y las melodías restauradas en el siglo XVI. El trabajo que sigue tiene por objeto corroborar esta hipótesis o bien, rebatirla. Para trabajar alrededor de esta hipótesis se han planteado una serie de objetivos que han dado como resultado una tesis doctoral dividida en tres partes bien diferenciadas. En la primera parte se aborda el estudio de la la comunidad mozárabe de Toledo, su evolución y rasgos distintivos, algunos intentos de restauración o apoyo del rito hispánico anteriores a Cisneros y, finalmente, la última y definitiva recuperación del Cardenal que se sustentaría en varios frentes: una capilla propia, unos libros litúrgicos y unas melodías identificables como mozárabes. El principal resultado de esta primera parte ha sido la constatación de la desaparición de la identidad mozárabe, cuya denominación se mantuvo a lo largo del tiempo sobre todo en forma de una serie de privilegios reales; sin embargo, el deterioro progresivo del rito hispánico fue inevitable y sus manuscritos quedaron como una especie de reliquias que albergaban unas melodías en forma de neumas indescifrables hasta que el Cardenal Cisneros consiguió revitalizarlo, incluyendo la música...This doctoral dissertation, titled “Cisneros’ Cantorales: from Hispanic chant to Neo-Mozarab chant”, explores the restoration of the so-called Hispanic chant carried out in the early 16th Century by Cardinal Jiménez de Cisneros, trying to show how the melodies from Cisneros’ Cantorales were constructed. After reading several previous works on the subject, a hypothesis around which this investigation revolves is formulated, namely the idea that there is an objectively demonstrable, direct link between medieval Hispanic chant and the melodies restored in the 16th Century. The purpose of the following research is either to corroborate it or to refute it. To work around this hypothesis a number of objectives are specified, resulting in a doctoral dissertation with three well-defined parts. The first part addresses the study of the Mozarab community in the city of Toledo, its evolution and distinctive characteristics, as well as some attempts at restoring or supporting the Hispanic chant made before Cisneros, and finally, the recuperation ultimately carried out by Cisneros with the creation of a special chapel, some liturgical books and an assortment of melodies of Mozarab character. The main result of this first part is the identification of the dissolution of Mozarab identity, a denomination that was held for some time in Spain, especially in the form of a number of royal privileges; however, the progressive deterioration of the Hispanic rite was inevitable and their manuscripts were kept as some kind of ancient relics containing melodies in the form of undecipherable neumes, until Cardinal Cisneros was able to revitalize them, including the music...Depto. de MusicologíaFac. de Geografía e HistoriaTRUEunpu

Influence of temperature on the interaction between Pd clusters and the TiO2 (110) surface

The behavior of a Pd nanocluster on the rutile TiO2 (110) surface has been analyzed by extensive first principles molecular dynamics simulations between 100 K and 1073 K. Calculations predict a steep change in the morphological and electronic cluster structure around 800 K in excellent agreement with previous experimental evidence. At low temperature, the cluster geometry is mainly controlled by the substrate structure; however, upon the transition temperature, the cluster-substrate interaction decreases appreciably, and the cluster adopts a geometry more stable in vacuum and becomes metallic. These results illustrate at an atomistic level the influence of temperature on the geometrical and electronic properties of oxide-supported clusters.Ministerio de Educación y Ciencia MAT2005-0187

Oxygen vacancies on TiO2 (110) from first principles calculations

We have carried out a systematic study of oxygen vacancy formation on the TiO2 ~110! surface by means of plane-wave pseudopotential density-functional theory calculations. We have used models with the mean number of vacancies per surface unit cell being u50.25 and u50.5. The study comprises several kind of vacancies within the outermost layers of the surface. The use of a suitable set of technical parameter is often essential in order to get accurate results. We find that the presence of bridging vacancies is energetically favored in accordance to experimental data, although the formation of sub-bridging vacancies might be possible at moderate temperatures. Surprisingly, the spin state of the vacancy has little influence on the results. Atomic displacements are also analyzed and found to be strongly dependent on the particular arrangement of vacancies.Dirección General de Enseñanza Superior e Investigación Científica.

¿Cómo evaluamos las nanopartículas?

IX Congreso Nacional de Evaluación de Impacto Ambiental. Zaragoza 28-30 Marzo 2017El uso de nano materiales en los últimos años, supone el desarrollo de nuevas oportunidades y retos en nuestras vida diaria. Los nanomateriales permiten el desarrollo de nuevas tecnologías que servirán para proteger el medio ambiente y al mismo tiempo ya se están liberando al medio ambiente nanopartículas de diferente composición y origen que pueden producir potenciales impactos ambientales. En el momento actual, no existe un marco regulatorio consensuado por la comunidad científica que permita valorar los efectos toxicológicos ni ambientales de estas nanopartículas ni en los organismos ni sistemas. En esta comunicación se presenta una breve revisión del estado del arte de los principales retos a los cuales hay que enfrentarse para acometer con éxito un procedimiento de  evaluación ambiental basándonos en el análisis de casos de éxito.Peer reviewe

Effect of hyperlipidic diets on normal and abnormal aortic valves in the Syrian hamster: A preliminary study

Effect of hyperlipidic diets on normal and abnormal aortic valves in the Syrian hamster: A preliminary study. MC Fernández 1,2, J Moncayo-Arlandi 1, MT Soto 1, MA López-Unzu 1, B Fernández 1,2 and AC Durán 1,2. 1 Department of Animal Biology, Faculty of Science, University of Málaga, Spain. 2 Biomedical Research Institute of Málaga (IBIMA), University of Málaga, Spain. Bicuspid aortic valve (BAV) is the most frequent human congenital cardiac malformation. It frequently becomes stenotic due to calcification by an atherosclerosis-like process. Hyperlipidic diets have been classically used to induce atherosclerosis in laboratory animals, including Syrian hamsters. The aim here is to evaluate the effect of hyperlipidic diets in hamsters having different incidence of BAVs. We used a unique inbred strain of Syrian hamsters with a high ( 40%) incidence of spontaneous BAV, morphologically similar to that in man, another inbred strain with a low ( 4%) incidence of BAV, and an outbred, second control line, acquired from Charles River Laboratories. Three experimental groups were fed with standard diet supplemented with 2% cholesterol plus 15% butter during five months. In parallel, three control groups were fed with unmodified standard diet. Hyperlipidic diets induced lesions in the aortic valve and ascending aortic wall, i.e. subendothelial lipid deposits, valve sclerosis, and neo-intima in the aorta. We performed a preliminary, qualitative, comparative study of the lesions associated with the different animal populations and valvular phenotypes. Our results indicate that (1) the type and severity of the lesions varied among the three hamster populations, suggesting that genetic factors may be involved; (2) the aortic valve morphology seems not to determine the severity of the valvular lesions. We conclude that our hamster strain with high incidence of BAV is a promising animal model for studies on human aortic stenosis. This work was supported by P10-CTS-6068.Universidad de Málaga.

Functional activation and connectivity of the left inferior frontal gyrus during lexical and phonological retrieval

Being language a paradigm of structural and functional asymmetry in cognitive processing, the left Inferior Frontal Gyrus has been consistently related to speech production. In fact, it has been considered a key node in cortical networks responsible for different components of naming. However, isolating these components (e.g., lexical, syntactic, and phonological retrieval) in neuroimaging studies is difficult due to the use of different baselines and tasks. In the present study, functional activation and connectivity of the left inferior frontal gyrus was explored using functional magnetic resonance imaging. Participants performed a covert naming task (pressing a button based on a phonological characteristic). Two conditions were compared: drawings of objects and single letters (baseline condition). Differences in activation and functional connectivity were obtained for objects and letters in different areas of the left Inferior Frontal Gyrus. The pars triangularis was involved in the retrieval of lexical-phonological information, showing a pattern of connectivity with temporal areas in the search for the name of objects and with perisylvanian areas for letters. Selection of phonological information seems to involve the pars opercularis both to letters and objects but recruiting supramarginal and superior temporal areas to letters, probably related to orthographicphonological conversion. The results support the notion of the left Inferior Frontal Gyrus as a buffer forwarding neural information across cortical networks responsible for different components of speech productionThis research was funded by the Spanish Ministerio de Economía y Competitividad (Grant number: PSI2013 43594-R), Consellería de Cultura, Educación e Ordenación Universitaria, Xunta de Galicia (Grant number: ED431C-2021/04, from the EDRF/FEDER) and by a post-doctoral fellowship from Consellería de Cultura, Educación e Ordenación Universitaria, Xunta de Galicia (Grant number: ED481B2016/078-0).
