No full textLo scopo della tesi è valutare gli effetti di un programma di riabilitazione cardiorespiratoria in pazienti in esiti di chirurgia valvolare aortica e/o con cardiopatia ischemica cronica rivascolarizzata, incentrato sul training aerobico, sull'efficienza cardiopolmonare, sulla risposta cronotropa e pressoria tramite test di valutazione funzionale ed emodinamici nella fase post acuta. Il periodo di training riabilitativo avverrà in un regime ospedaliero presso la Clinica Hildebrand, Centro di riabiliazione Brissago (cH), nell'immediata fase post-chirurgica in collaborazione con il Dott.Cardiologo Davide Girola
Classical theta constants vs. lattice theta series, and super string partition functions
No full textRecently, various possible expressions for the vacuum-to-vacuum superstring amplitudes has been proposed at genus g = 3, 4, 5. To compare the different proposals, here we will present a careful analysis of the comparison between the two main technical tools adopted to realize the proposals: the classical theta constants and the lattice theta series. We compute the relevant Fourier coefficients in order to relate the two spaces. We will prove the equivalence up to genus 4. In genus five we will show that the solutions are equivalent modulo the Schottky form and coincide if we impose the vanishing of the cosmological constant
Rencontrer des personnes sans abri. Une anthropologie réflexive
No full textAnthropologisf s methodological itinerary : reflexivity, a theoretico-methodological choice or how to go beyond the story of the presentation.
Claudia M. Girola [87-98].
Through a presentation of a fragment of her methodological itinerary in the study of homeless people's identity strategies, the author underlines the importance of field-work as the matrix for understanding the social reality being observed. The multiplicity of identities, both of the researcher and of the agents of the study emerge from their encounter ; which is viewed as a process of mutual understanding and self-knowledge. Here in lies the fertility of this reflexive approach especially when working with people experiencing extreme pauverty and continual stigmatization. For such an analysis undermines reducing representations of these «solitary and rootless figures», thus revealing the complexities of their biographical histories, in a social context.Itinéraire méthodologique d'un anthropologue : la réflexivité, un choix théorico-méthodologkjue ou comment dépasser le récit de la présentation.
Claudia M. Girola [87-98].
En exposant un fragment de son itinéraire méthodologique dans l'étude des stratégies identitaires des personnes sans-abri, l'auteur a voulu signaler l'importance du travail de terrain (d'un point de vue d'une anthropologie réflexive) comme l'instance même de la production de la connaissance de la réalité sociale qu'on se propose de comprendre. Dans la rencontre entre chercheur et acteurs de la recherche considérée comme un processus d'interconnaissance active émerge la multiplicité de leurs appartenances réciproques. C'est là toute la richesse de cette démarche réflexive, surtout losqu'on travaille avec des personnes en situation de précarité extrême et de stigmatisation permanente. Ce processus analytique contribue à briser les images et les représentations réductrices dont sont «victimes» ces «hommes seuls, sans lien ni lieu» en permettant la reconnaissance de la complexité de leurs appartenances individuelles dans un monde social.Girola Claudia M.

Tecnología: ¿Ideología e Imaginario? Aproximaciones teórico-empíricas desde México
No full textFirst, this paper proposes to make a brief conceptual revision between the notions of social imaginaries,
social representations, mentalities and ideology. Second, differentiate the technological ideology from
technological social imaginary. Finally, the author tries to illustrate the tendency to the predominance of
technological imaginary in Mexican society.En primer lugar, este artículo se propone hacer una breve revisión conceptual, entre las nociones de

El surgimiento de la megaurbanización Nordelta en la Región Metropolitana de Buenos Aires: consideraciones en torno a las nociones de ciudad-fragmento y comunidad purificada / The Emergence of the Nordelta Megaurbanization in the Metropolitan Region of Bu
No full textEn este artículo se focaliza uno de los procesos más generalizados y polémicos que se registran en las grandes ciudades contemporáneas: el desarrollo de conjuntos residenciales que cuentan con seguridad y que sirven de vivienda permanente a los sectores medios y altos de la población. Más concretamente, intentamos cuestionar y examinar –desde una perspectiva etnográfica– las visiones sobre estos conjuntos ancladas en torno a la categoría de fragmentación urbana, a partir del análisis de un ejemplo específico: la emergencia de grandes emprendimientos en la Región Área Metropolitana de Buenos Aires; en este caso se trata de una singular ciudad privada y periférica. AbstractThis article focuses on one of the most generalized, polemic processes recorded in major contemporary cities: the development of residential complexes with security that serve as permanent housing for the middle and upper classes of the population. More specifically, the author attempts to use an ethnographic perspective to question the views on these complexes placed within the category of urban fragmentation on the basis of the analysis of a specific example; the emergence of major developments in the Metropolitan Area of Buenos Aires; in this case, an unusual private, peripheral city.</jats:p

Session A5: A Dam Removal in Robledo de Chavela (Madrid, Spain) and River Restoration
No full textPresenting Author Bio: Mr. Miguel Antolín Martínez, Dr. Ingeniero de Caminos, Canales y Puertos (this means, pure Civil Engineer), is the current President of the Tajo River Basin Authority since March 2012. Before being elected for this position, he was in charge of the International Affairs Unit of the Directorate General for Water (Ministry of Agriculture, Food and Environment), and previously Head of Water Director Support Unit, and, therefore, more than 25 years of professional career within the public management of water.Abstract: The Robledo de Chavela dam removal can be considered a milestone in river restoration as, due to its 23 meters high, is the highest dam ever demolished in Spain and probably in all Europe. The dam was located in Cofio river (belonging to Tajo river basin), 70 km northwest from Madrid. It was built for supplying purposes during the early sixties, but few years later it became unusable, due to water quality problems caused by livestock discharges from upstream. On June 8th, 2012, the Tajo River Basin Authority (Confederación Hidrográfica del Tajo, CHT) detected a water leak from the drain line impossible to repair, and, consequently, launched urgent measures to avoid an extreme fish death in the reservoir and also sediment transport downstream. The CHT carried out a massive electric fishing in order to transfer fish population from the empty reservoir to downstream. For security reasons, sediments were analyzed to confirm that heavy metal concentration, ecotoxicity and irritability were under legal limits. When dry enough, sediments were removed from the reservoir to an old meander upstream. Slopes were reprofiled and reinforced by a breakwater wall. To prevent erosion, revegetation was accomplished by hydroseeding and native trees and bushes plantation. On September 2014 the final crucial task was achieved: the dam removal. A highly specialized company was hired in order to reach the goal of an efficient detonation, taking into account that more than 9.000 m3 of concrete had to be reduced into small pieces. Next three months were spent in removing the concrete waste from the river. The main part of it was crushed and used to restore paths in the surroundings, and the rest was disposed in the lower parts of the river banks to prevent erosion
Tradução: Encontrar-se com as pessoas em situação de rua. Uma antropologia reflexiva
No full textItinerário metodológico de um antropólogo: reflexividade, uma escolha teórico-metodológica ou como ultrapassar o relato da apresentação. Expondo um fragmento de seu itinerário metodológico no estudo das estratégias identitárias das pessoas que moram na rua, a autora quis assinalar a importância do trabalho de campo (de um ponto de vista de uma antropologia reflexiva) como o instante mesmo da produção do conhecimento da realidade social que se propõe compreender. No encontro entre pesquisador e atores da pesquisa, considerado como um processo de interconhecimento ativo, emerge a multiplicidade de seus pertencimentos recíprocos. Está aí toda a riqueza deste procedimento reflexivo, sobretudo quando se trabalha com pessoas em situação de precariedade extrema e de estigmatização permanente. Este processo analítico contribui a quebrar as imagens e as representações redutoras de que são “vítimas” estes “homens sozinhos, sem vínculo nem lugar” permitindo o reconhecimento da complexidade de seus pertencimentos individuais no mundo social.

International validation of the Metabolic Exercise test data combined with Cardiac and Kidney Indexes (MECKI) score in heart failure
No full textBackground: Current European heart failure (HF) Guidelines suggests the use of risk score: among them, the Metabolic Exercise test data combined with Cardiac and Kidney Indexes (MECKI) score has demonstrated to be one of the most accurate. However, the risk scores are still poorly implemented in clinical practice, also due to lack of strong evidence regarding their external validation in different populations. Thus, the current study was designed as an external validation test of the MECKI score in an international multicentre setting. Methods: The study cohort consisted of patients diagnosed with HF with reduced ejection fraction (HFrEF) across international centres (not Italian), retrospectively recruited. Collected data included demographics, HF aetiology, laboratory testing, ECG, echocardiographic findings, cardiopulmonary exercise testing (CPET) results as described in the original MECKI score publication. Results: 1042 patients across 8 international centres (7 European and 1 Asian) were included and followed up from 1998 till 2019. Patients were divided according to the calculated MECKI scores into 3 subgroups: (i) MECKI score <10%; (ii) 10-20%; (iii) ≥20%. Survival analysis comparison among the 3 MECKI score subgroups showed a worse prognosis in patients with higher MECKI score value: median event-free survival times were 4396 days for MECKI score <10%; 3457 days for 10-20%; 1022 days for ≥20% (p<0.0001). ROC curves and the AUC curves were like those reported in the original internal validation studies. Conclusion: In patients diagnosed with HFrEF, the power of the MECKI score was confirmed in terms of prognosis and risk stratification, supporting its implementation as advised by the HF Guidelines
Prognostic role of atrial fibrillation in patients affected by chronic heart failure. Data from the MECKI score research group
No full textAtrial fibrillation (AF) is common in heart failure (HF). It is unclear whether AF has an independent prognostic role in HF. The aim of the present study was to assess the prognostic role of AF in HF patients with reduced ejection fraction (EF)
