Un viaje a Santiago del autor entrega una experiencia de recorrido de la ciudad y del río Mapocho, que muchas veces no somos capaces de ver y comprender. La existencia de una particular topografía y del cauce del río son determinantes de un paisaje, una trama urbana compleja y de situaciones particulares que enriquecen la ciudad.An author’s trip to Santiago offers an experience of the city’s and Mapocho River’s promenade, which we are often not able to see and understand. The existence of a particular topography and a river bed are the determinants of landscape, a complex urban scheme, and the particular situations that enrich the city

Una tesis urbanística sobre Córdoba
Reseña sobre la tesis doctoral Córdoba y el Guadalquivir, permanencia y flujo. Cuatro miradas ciudad-río, atravesando el tiempo, defendida en la Universidad de Granada, en 2013, por el arquitecto Fernando Osuna Pérez
La ciudad histórica: detrás de las fachadas, la forma del suelo
The starting point is a teaching experience at the ETSAG (School of Architecture, Granada), which proposed to the students the feeling walking around through the city. The paper, after outlining this experience, continues arguing on the complex nature of urban change and recommends paying more attention to the urban morphology and to the processes of evolution of particular cities, commonly neglected by urban stories that are anchored in general, national, social and economic factors. It describes the processes of commercial and tertiary specialization and the residential emptying of our historic centers, where the meaning of space-time is fading. Arterial streets, specialized for traffic, are an example of this loss. The morphological study is proposed as the basis for an encounter with memory.Se parte de una experiencia docente en la ETS de Arquitectura de Granada que propuso a los alumnos el ejercicio de hacer y sentir unos paseos por la ciudad. Tras esbozar esta experiencia, se prosigue reflexionando sobre la compleja naturaleza delas transformaciones urbanas y la necesidad de prestar más atención a la forma urbana y a los procesos de evolución de cada ciudad en particular, comúnmente desatendidos por las historias urbanas que se anclan en factores generales de las naciones. Se describen los procesos de especialización comercial y terciaria y de vaciado residencial de nuestros centros históricos, cuyo significado espacio-temporal se va desvaneciendo. La calle especializada para circular es un ejemplo de esta pérdida. El estudio morfológico y parcelario se plantea como la base de un reencuentro con la memoria
Feshbach-like study of He resonant states in Debye plasmas using explicitly correlated wave functions
ABSTRACT: We present a study on the 1;3Se, 1;3Po and 1;3De He resonant states below the He+ (N=2) threshold under the in uence of a plasma environment, when the Debye screening length is varied. The interaction between all charged particles is modeled with Yukawa-like screened Coulomb potentials. We make use of the Feshbach
projector method to characterize resonant states, implemented by using explicitly correlated CI-wave functions
Feshbach projection approach to study plasma effects on doubly excited autoionizing states in helium
ABSTRACT: We have implemented a method based on the Feshbach formalism along with an explicitly correlated configuration interactionmethod to perform a systematic study on the behavior of resonance parameters (energies and lifetimes) of the autoionizing states of plasma-embedded He 1,3Se, 1,3Po, and 1,3De, as a function of the screening strength. In particular, we study the evolution of the lowest states in the series located below the He+(N = 2) ionization threshold in the unscreened case. At variance with one-electron atoms (where shape resonance widths vary monotonically with the screening strength) the evolution of the Auger width with respect to screening is found to be different for each series represented by (K,T )A pseudoquantum numbers until resonances merge into the upper electronic continuum, when crossing the He+(2s) threshold. We conclude from our ab initio calculations that, although resonances pertaining to the same (K,T )A series share a similar tendency in their widths against the screening strength, general propensity rules for the robustness of lifetimes, based on the isomorphic series in the (K,T )A classification, cannot be established in plasma embedded helium

Renal Function Impact in the Prognostic Value of Galectin-3 in Acute Heart Failure
[Abstract] Introduction: Galectin-3 (Gal-3) is an inflammatory marker associated with the development and progression of heart failure (HF). A close relationship between Gal-3 levels and renal function has been observed, but data on their interaction in patients with acute HF (AHF) are scarce. We aim to assess the prognostic relationship between renal function and Gal-3 during an AHF episode.
Materials and methods: This is an observational, prospective, multicenter registry of patients hospitalized for AHF. Patients were divided into two groups according to estimated glomerular filtration rate (eGFR): preserved renal function (eGFR ≥ 60 mL/min/1.73 m2) and renal dysfunction (eGFR <60 mL/min/1.73 m2). Cox regression analysis was performed to evaluate the association between Gal-3 and 12-month mortality.
Results: We included 1,201 patients in whom Gal-3 values were assessed at admission. The median value of Gal-3 in our population was 23.2 ng/mL (17.3-32.1). Gal-3 showed a negative correlation with eGFR (rho = -0.51; p < 0.001). Gal-3 concentrations were associated with higher mortality risk in the multivariate analysis after adjusting for eGFR and other prognostic variables [HR = 1.010 (95%-CI: 1.001-1.018); p = 0.038]. However, the prognostic value of Gal-3 was restricted to patients with renal dysfunction [HR = 1.010 (95%-CI: 1.001-1.019), p = 0.033] with optimal cutoff point of 31.5 ng/mL, with no prognostic value in the group with preserved renal function [HR = 0.990 (95%-CI: 0.964-1.017); p = 0.472].
Conclusions: Gal-3 is a marker of high mortality in patients with acute HF and renal dysfunction. Renal function influences the prognostic value of Gal-3 levels, which should be adjusted by eGFR for a correct interpretation.Grant No. RD06-0003-0000

The urban project. The end of degree project
Ésta es una publicación que explica nuestra experien¬cia docente en la invención de estrategias para el territorio urbano, basadas en el proyecto como instrumento de in¬tervención; un método que presenta características de los planes a la vez que de los proyectos arquitectónicos, con ideas que van más allá del artefacto que proponen y del lugar estricto en que se implantan.
Comoquiera que este libro se dedica a presentar los pro¬yectos fin de carrera de los estudiantes de Arquitectura que han elegido elaborar propuestas que siguen esta línea arquitectónico-urbanística.
Desde nuestra joven Escuela de Arquitectura de Granada, quisiéramos ver arraigar y desarrollar algunos de los atributos que se presentanen el prólogo de Joan Busquets, destacado urbanista y pro¬fesor. Obviamente, la generosa autoriza-ción para publicar este texto, quiere significar para noso¬tros, y así lo sugerimos a nuestros alumnos y lectores, una referencia de calidad para seguir profundizando y mejoran¬do en el camino emprendido. Que no es otro que el empeño de contribuir al bienestar más igualitario de los ciudadanos en los territorios en que transcurren sus vidas.
The implication of the University in the problems of the so¬ciety and the territory of its environment and of its time, constitutes a major exigency more the university institution spreads toal most all the cities of our country, all more cons¬cience is of that the knowledge is an essential vector of our time and major they are the requirements of innovation to face the emergent problems of extensive urbanization and environmental deterioration.
Thisuniversitycommitmentwithitsenviromentissufficientlyrecognizedwhenonespeaksaboutinvestigation but is re comforting also to recognize it in educational efforts like that here we preface.
The teaching is formation of human resources and frame of possible confluence of universal concepts with the local conditions. To the margin of this confrontation of generic values with a few historical - social precise and local needs, those resources would not conform as share capital, as so¬lidary with a collective project.
In these publications of the a Area of Urban development and Land management of one of its years in the Technical Top School of Architecture, it is necessary to admit this effort of commitment between the global thing and the lo¬cal thing, between the knowledge and the practice, between culture and society. It is necessary to recognize, to support its continuity and contagious diffusion it and it be grateful to all by those, teachers and pupils, who have collaborated both in the curses and in the publications.Junta de Andalucía y Universidad de Granad
