Résumé :
En las últimas dos décadas el “Calcio Fiorentino” ha experimentado un proceso de difusión considerable, principalmente gracias a los nuevos medios de comunicación, que han despertado cierto interés por lo que se ha definido como el “deporte más violento del mundo”. La proyección internacional del Calcio Fiorentino ha creado una importante cantidad de material de estudio, fuentes de información relevantes que nos invitan a re-interpretar este fenómeno, entre patrimonio cultural y deportivo. El carácter de representación histórica y de re-evocación de una tradición popular se mezcla con los elementos propios de la actividad deportiva: la competición, el agonismo, la fuerza física y la violencia. Este artículo se centra en la doble vertiente del Calcio Fiorentino, sólo aparentemente contradictoria: historia y presente permiten captar características específicas del deporte actual y su relación con espacios, tradiciones culturales y nuevos conflictos. Por un lado, el carácter de representación y re-evocación del calcio fiorentino sugiere una reflexión sobre la transformación de la violencia en el deporte moderno. Por otro lado se considera el delicado equilibrio entre tradiciones, identidades y conflictos, en contexto de metamorfosis urbanas.

Résumé :
En este trabajo se presenta un análisis integral del registro sedimentario y paleopedológico en una secuencia edafo-sedimentaria encontrada en la terraza baja del arroyo Tinajas, estado de Sonora. El objetivo de esta investigación es establecer los mecanismos de formación de dicha secuencia que permitan hacer una reconstrucción de las condiciones paleoambientales. La secuencia consiste de un suelo moderno y once paleosuelos intercalados con sedimentos fluviales. Se determinaron sus propiedades físicas (color, granulometría), químicas (pH, conductividad eléctrica, contenido de calcio total), de magnetismo de rocas y micromorfológicas. Así mismo, se hizo la identificación de la mineralogía de arcilla por difracción de rayos X. Prácticamente todos los paleosuelos están decapitados. Debido a la falta de horizontes A, el marco cronológico de la secuencia se obtuvo usando una pequeña cantidad de materia orgánica encontrada en el paleosuelo 8. Para concentrar la materia orgánica, se hizo una extracción por desmineralización con ácido fluorhídrico. Esta materia orgánica desmineralizada se dató por 14C por la técnica de AMS (Accelerator Mass Spectrometry), arrojando una edad de 8415 ± 39 años cal AP (Beta 473502). Los resultados muestran que los paleosuelos tienen un bajo grado de desarrollo. A pesar de ello, es posible establecer las principales tendencias pedogenéticas: la parte baja de la secuencia muestra paleosuelos de granulometría fina, con fuertes rasgos reductomórficos y propiedades vérticas. En contraste, los paleosuelos superiores son de textura más gruesa, con mayor porosidad biogénica e, inclusive, con revestimientos arcillosos. A partir del paleosuelo 7, se aprecia un cambio en la energía del relieve, dado por variaciones sedimentológicas (gradación inversa, aumento del tamaño de grano del sedimento), el cual es más evidente en los paleosuelos 2, 3 y 4, dada la alta concentración de gravas, mal seleccionadas y angulosas, que se asocian con procesos fluvio-coluviales. Suponemos que este cambio en el tipo de pedogénesis, sumado a las variaciones sedimentológicas, es debido a oscilaciones climáticas ocurridas en el Holoceno medio a nivel regional, ya que no se tiene documentada actividad tectónica reciente que pudiera influir.

Résumé :
El moderno término «consonante» deriva evidentemente del latino consonans, que, a su vez, es un calco semántico del griego σύμφωνον. El presente trabajo trata de rastrear la historia de uno y otro término y someter a crítica algunos de los tratamientos modernos de que han sido objeto. Tradicionalmente, se ha considerado como primera aparición de la denominación σύμφωνα para designar al conjunto de las que hoy llamamos consonantes la que muestra la Τέχνη γραμματική atribuida al filólogo alejandrino Dionisio Tracio (siglo II a. C.), cuya autenticidad, sin embargo, es, cuando menos, sospechosa para la moderna crítica. Por su parte, el término latino consonans está acreditado por primera vez en Quintiliano, a finales del siglo I d. C.

Résumé :
According to the results of the study of soils in the Northwest of the Black Sea region, it is determined that here, in the profile of vorony-calcic and calcic Chernozems, both residual and weak alkalinity are manifested. It was found out, nowadays, in the national soil science, there are no clear criteria for the selection of sodic soils and for the determination of their alkalinity degree. Furthermore, there is also the question of the differentiation of the actually sodic and residual-sodic soils. It has been established that on the territory of the Northwest of the Black Sea region polygenetic soils – vorony-calcic and calcic Chernozems weakly and residual-sodic were formed and the diagnostics of their classification and taxonomic position for the moment is rather ambiguous. The diagnostic of the alkalinity degree of vorony-calcic and calcic Chernozems in the Northwest of the Black Sea region was carried out in four methodological approaches. It was established, that it is impossible to carry out precise and unambiguous diagnostics of the alkalinity degree of soils of the territory of the study according to existing methods. Thus, the sodic and residual-sodic soils, according to classification of 1977, are almost entirely positioned as weakly sodic in accordance with the “Field determinant of soils”. In turn, taking into account the Novikova approach, the status of these same soils varies from non-sodic to solonetzes according to the degree of illuviation, the final diagnosis of which, however, contradicts the low content of exchangeable sodium. An integral approach to the determination of the alkalinity degree of soils is proposed, which is based on the chronological features of the course and direction of the sodification process. According to this approach, if the alkalinity of the studied soils is relict, its degree should be diagnosed by the illuviation of silt and by the content of exchange Na+ (Ni> 8 %, Na+<3 % – residual-sodic soils, Ni> 8 %, Na+ ≥ 3 % –sodic soils).In turn, in the case of the modern alkalinity, its degree should be determined by the ratio Ca2+/Mg2+ (<4,8) and by the content of the exchangeable Na+ (<3 % – residual-sodic soils, and ≥3 % – sodic soils). Key words: Chernozems, the alkalinity degree, diagnostic, steppe, the Northwest of the Black Sea region.

Trouver le texte intégral
Résumé :
Il 13 maggio 2017 la S.P.A.L. , ha ottenuto la promozione in Serie A. Da qui l'esigenza di programmare dei lavori di ristrutturazione e ampliamento dello stadio Paolo Mazza, per soddisfare i criteri infrastrutturali imposti dalla Lega. In questa tesi si propone un progetto che non si limita ad adeguare l'impianto a tali parametri, ma è finalizzato a trasformare il Paolo Mazza in un'arena moderna e multifunzionale. Si prevede la costruzione della nuova Tribuna Nord, della Curva Est e dei quattro curvini necessari a raccordare tutti i settori dello stadio. Si propone la realizzazione di un nuovo sistema di copertura, che garantisca un riparo a ogni spettatore. Attraverso questa serie di interventi, si prevede di raggiungere la capienza complessiva di 16˙078 posti a sedere. La tesi è suddivisa in sei capitoli. Nel primo capitolo vengono analizzate le peculiarità costruttive degli stadi realizzati da Pier Luigi Nervi, uno dei più grandi progettisti dello scorso secolo. Nel secondo capitolo si pone l’attenzione sulle caratteristiche degli impianti moderni, utilizzando alcuni esempi significativi. Gli stadi di ultima generazione ospitano diversi tipi di eventi e servizi, mantenendo l’impianto sempre attivo anche al di fuori del singolo evento sportivo. Nel terzo capitolo viene ripercorsa la storia dello stadio Paolo Mazza, soffermandosi sulle diverse ristrutturazioni che hanno interessato l’impianto nel corso degli anni. Nel quarto capitolo si descrive dal punto di vista architettonico la ristrutturazione proposta per il Paolo Mazza. Il quinto capitolo riporta i calcoli strutturali effettuati per il predimensionamento del sistema di copertura della Curva Ovest. La tesi si conclude con considerazioni sulla funzione chiave che può avere uno stadio moderno, se inserito opportunamente nella città di Ferrara. Un'opera di questo genere costituirebbe un polo di attrazione, non alternativo ma sinergico con il centro storico, e consentirebbe di valorizzare la città estense.

Résumé :
Aims: To investigate in vitro the effect of Calcium Phosphate delivering technologies: Tooth Mousse (10% w/v CPP-ACP), MI paste Plus (10% w/v CPP-ACP, 900 ppm F), Clinpro 5000 (Tri-Calcium Phosphate, 5000 ppm F), Clinpro Tooth Crème ( Tri-Calcium Phosphate, 950 ppm F) in the remineralisation of artificial enamel subsurface lesions of bovine teeth and compare it with the effect of 1450 ppm F, 5000 ppm F, and 0 ppm F toothpastes using Quantitative Light-induced Fluorescence (QLF) technology. Materials and Methods: Artificial enamel subsurface lesions were created in bovine enamel slabs (N=182) which were assigned randomly to seven groups; (1) Fluoride-free Toothpaste (negative control), (2) 1450 ppm F toothpaste (positive control), (3) 5000 ppm F toothpaste, (4) 1450 ppm F toothpaste + Tooth Mousse (10% w/v CPP-ACP), (5) 1450 ppm F toothpaste + MI Paste Plus (10% w/v CPP-ACP, 900 ppm F), (6) Clinpro 5000 (Tri-Calcium Phosphate, 5000 ppm F), and (7) Clinpro Tooth Crème ( Tri-Calcium Phosphate, 950 ppm F). All the experimental products were used according to the manufacturer recommendation of dosage. The enamel slabs were cycled for 28 days, QLF images were taken at the baseline and at the endpoint of the experiment. Data analysis was carried out using one-way analysis of variance (One way ANOVA). Results: There were significant improvements in QLF values with all remineralising agents at the end of the study compared with baseline values within each group (P < 0.05). All groups showed a statistically significant improvement in ΔQ and Area of the lesion values compared with negative control (0 ppm fluoride) (P < 0.05). In term of ΔF values measurement, Clinpro Tooth crème was significantly more effective than high fluoride toothpaste (5000 ppm F) (P < 0.05). 5000 ppm fluoride toothpaste was not different significantly to either Clinpro 5000 or the fluoride-free toothpaste (P > 0.05). Conclusion: All group products were significantly more effective as remineralising agents of artificial early enamel subsurface lesions as compared with the negative control 0 ppm F. Calcium Phosphate delivering technologies; CPP-ACP with and without fluoride and Tri-Calcium Phosphate products were as effective as fluoridated toothpastes (1450 ppm F and 5000 ppm F) in remineralising artificial early enamel subsurface lesions. Tooth Mousse was as effective as MI Paste Plus when used in conjunction with 1450 ppm F toothpaste in remineralising artificial early enamel subsurface lesions in bovine teeth assessed using QLF technology.

Simon, Bertrand. « Ordonnancement de graphes de tâches sur des plates-formes de calcul modernes ». Thesis, Lyon, 2018. http://www.theses.fr/2018LYSEN022/document.

Texte intégral
Résumé :
Cette thèse porte sur trois thématiques principales liées à l'ordonnancement de graphes de tâches sur des plates-formes de calcul modernes. Un graphe de tâches est une modélisation classique d'un programme à exécuter, par exemple une application de calcul scientifique. La décomposition d'une application en différentes tâches permet d'exploiter le parallélisme potentiel de cette application sans adapter le programme à la plate-forme de calcul visée. Le graphe décrit ces tâches ainsi que leurs dépendances, certaines tâches ne pouvant être exécutées avant que d'autres ne soient terminées. L'exécution d'une application est alors déterminée par un ordonnancement du graphe, calculé par un logiciel dédié, qui décrit entre autres quelles ressources sont allouées à chaque tâche et à quel moment. Les trois thèmes étudiés sont les suivants: exploiter le parallélisme intrinsèque des tâches, utiliser des accélérateurs tels que des GPU, et prendre en compte une mémoire limitée.Certaines applications présentent deux types de parallélisme que l'on peut exploiter: plusieurs tâches peuvent être exécutées simultanément, et chaque tâche peut être exécutée sur plusieurs processeurs afin de réduire son temps de calcul. Nous proposons et étudions deux modèles permettant de régir ce temps de calcul, afin d'exploiter ces deux types de parallélisme.Nous étudions ensuite comment utiliser efficacement des accélérateurs de calcul tels que des GPU, dans un contexte dynamique où les futures tâches à ordonnancer ne sont pas connues. La difficulté principale consiste à décider si une tâche doit être exécutée sur l'un des rares accélérateurs disponibles ou sur l'un des nombreux processeurs classiques. La dernière thématique abordée concerne le problème d'une mémoire principale limitée, et le recours à des transferts de données coûteux. Nous avons traité ce problème via deux scénarios. S'il est possible d'éviter de tels transferts, nous avons proposé de modifier le graphe afin de garantir que toute exécution ne dépasse pas la mémoire disponible, ce qui permet d'ordonnancemer les tâches dynamiquement au moment de l'exécution. Si tout ordonnancement nécessite des transferts, nous avons étudié le problème consistant à minimiser leur quantité.L'étude de ces trois thèmes a permis de mieux comprendre la complexité de ces problèmes. Les solutions proposées dans le cadre d'étude théorique pourront influencer de futures implémentations logicielles
This thesis deals with three main themes linked to task graph scheduling on modern computing platforms. A graph of tasks is a classical model of a program to be executed, for instance a scientific application. The decomposition of an application into several tasks allows to exploit the potential parallelism of this application without adaptating the program to the computing platform. The graph describes the tasks as well as their dependences, some tasks cannot be initiated before others are completed. The execution of an application is then determined by a schedule of the graph, computed by a dedicated software, which in particular describes which resources should be allocated to each task at which time. The three studied themes are the following: exploit inner task parallelism, use accelerators such as GPUs, and cope with a limited memory.For some applications, two types of parallelism can be exploited: several tasks can be executed concurrently, and each task may be executed on several processors, which reduces its processing time. We propose and study two models allowing to describe this processing time acceleration, in order to efficiently exploit both types of parallelism.We then study how to efficiently use accelerators such as GPUs, in a dynamic context in which the future tasks to schedule are unknown. The main difficulty consists in deciding whether a task should be executed on one of the rare available accelerators or on one of the many classical processors. The last theme covered in this thesis deals with a available main memory of limited size, and the resort to expensive data transfers. We focused on two scenarios. If it is possible to avoid such transfers, we propose to modify the graph in order to guarantee that any execution fits in memory, which allows to dynamically schedule the graph at runtime. If every schedule needs transfers, we studied how to minimize their quantity.The work on these three themes has led to a better understanding of the underlying complexities. The proposed theoretical solutions will influence future software implementations

Résumé :
Questo elaborato ha avuto come obiettivo la modifica di un modello matematico di potenziale d’azione ventricolare umano per migliorare la relazione che lega la durata del potenziale d’azione all’incremento degli intervalli diastolici, al fine di riprodurre correttamente i risultati sperimentali noti in letteratura. Ruolo principe nell’analisi e nell’implementazione di tale modello è stato quello dello ione calcio, coinvolto in numerosi processi chimici all’interno della cellula cardiaca, e responsabile anche della sua contrazione. Tutte le modifiche effettuate sono state fatte preservando la dipendenza inversa tra la durata del potenziale d’azione e le variazioni di calcio extracellulare, che costituiva il punto di forza del modello considerato rispetto alla sua versione originale. Le modifiche effettuate hanno riguardato in parte la struttura del modello (compartimenti, volumi) e in parte il calcium handling, ovvero la gestione del Ca2+ all’interno della cellula, in termini di flussi e correnti. Il modello così ottenuto, denominato “newORk”, è stato validato rispetto a numerosi protocolli sperimentali (sia di voltage-clamp, sia di current-clamp) presenti in letteratura e i risultati di simulazione hanno dimostrato un comportamento coerente con i risultati in vitro. In particolare la risposta del modello al protocollo S1S2, che non era fisiologica nel modello precedente, viene adesso riprodotta correttamente dal nuovo modello, presentando un aumento dell’APD all’aumentare dell’intervallo diastolico considerato. Il modello qui descritto può quindi essere ritenuto un importante, per quanto specifico, miglioramento nella descrizione matematica della elettrofisiologia cardiaca umana e potrà essere utilizzato per esplorare contesti clinici in cui le concentrazioni di calcio nel sistema cardiocircolatorio si modificano, come per esempio la terapia dialitica.

Résumé :
Il seguente elaborato affronta lo sviluppo di un modello di calcolo per la compressione e lo stoccaggio dell’idrogeno in forma gassosa tramite un compressore volumetrico a membrana, inserito all’interno del progetto internazionale Zero Emission Hydrogen Turbine Center (ZEHTC). L'analisi dal punto di vista termodinamico delle fasi di compressione e stoccaggio è stata effettuata nell'ambiente Visual Basic for Application (VBA) ed il modello elaborato consente di effettuare una previsione affidabile delle condizioni fisiche reali in ogni sezione del compressore a membrana e nel serbatoio di accumulo, tramite una serie di procedimenti iterativi che coinvolgono le pressioni e le temperature in gioco. Fondamentale è stato l'utilizzo del fattore di comprimibilità Z all'interno dell'equazione di stato, che lega pressione, temperatura e volume specifico relativi all'idrogeno gassoso, al fine di ottenere un buon riscontro dei dati con la realtà del fenomeno. Applicando questo modello alla sezione dell'impianto ZEHTC, deputata alla produzione e stoccaggio dell'idrogeno, e variando la potenza installata del fotovoltaico, il grado di riempimento del serbatoio e la taglia dell'elettrolizzatore, si è determinata la migliore configurazione che massimizza la produzione di idrogeno tramite elettrolisi, utilizzando l'energia elettrica proveniente dall'impianto fotovoltaico e quella prodotta da una turbina a gas, alimentata da una miscela di gas naturale ed idrogeno.

Résumé :
Questo lavoro di tesi, svolto presso AVIO S.P.A, sede di Colleferro (RM), divisione spazio, si inserisce all'interno del progetto Theseus, che ha come scopo finale lo sviluppo di un dimostratore di un motore ibrido a combustibile solido e ossidante gassoso. In particolare, in questo momento è richiesto un codice di calcolo, preciso ma allo stesso tempo abbastanza contenuto nei tempi di calcolo, che permetta l'analisi e le previsioni della balistica interna di tale motore ibrido. Il codice di calcolo si basa su una versione già esistente per i motori a solido (CUBIC) scritto in ambiente FORTRAN, ed è stato riadattato ai motori ibridi. In particolare è stata scritta una routine per il calcolo della velocità di combustione che tiene conto di diversi fattori, tra cui blowing e il fenomeno di entrainment presente in superficie. Sempre per quanto riguarda la velocità di combustione, nel suo calcolo si tiene conto dell'impingement dell'iniettore sul grano e del valore locale (per quanto riguarda la temperatura di fiamma) dell'O/F. Inoltre è stato anche modellato il comportamento termodinamico delle eventuali protezioni termiche presenti internamente al motore, considerando tutti i fenomeni di pirolisi e ablazione che caratterizzano tali materiali. In fine il modello completo è stato testato e validato grazie al fatto che si disponeva di alcuni tiri al banco di un motore ibrido, effettuati presso il dipartimento di Ingegneria Aerospaziale dell'Università di Napoli Federico II.

Résumé :
INTRODUZIONE. In oncologia, lo studio perfusionale consente di individuare i processi angiogenici tipici dei tumori e di monitorare gli effetti delle terapie anti-angiogeniche sulle sedi target. Una delle tecniche di imaging funzionale è la Tomografia Computerizzata perfusionale (TCp) eseguita con mezzo di contrasto (MdC), che consente di ricostruire le Time Concentration Curve (TCC) del MdC nei vasi sanguigni e nel tessuto. La convoluzione tra la TCC vascolare e la Impulse Residue Function (IRF) restituisce la TCC tessutale. Valutare la perfusione significa calcolare l’apporto di sangue al tessuto, mediante l’analisi della cinetica del MdC. Tra i metodi preposti vi sono il Maximum Slope (MS) e la deconvoluzione, che vuole stimare la IRF dalle TCC estratte, risolvendo quindi il problema inverso. OBIETTIVI. Il lavoro di Tesi nasce per calcolare i parametri perfusionali epatici, con modello mono compartimentale dual input. A questo scopo, si volevano approfondire le relazioni esistenti tra i diversi elementi coinvolti nel processo diretto di convoluzione, con particolare interesse per la IRF. METODI. È stato individuato un set di curve idonee a rappresentare la IRF e ne sono stati definiti metodi di calcolo automatici dei parametri, traendo informazioni dalle TCC reali. È stato quindi sviluppato un simulatore per generare TCC di tessuto, attraverso la convoluzione della IRF con TCC vascolari. Si è studiato un metodo di calcolo dei parametri perfusionali, effettuati sugli output del simulatore. I dati perfusionali sono stati analizzati con un classificatore non supervisionato, per individuare gruppi significativi di pazienti. RISULTATI. Il metodo è stato applicato per lo studio perfusionale di 10 pazienti. I dati ottenuti sono stati confrontati con quelli calcolati indipendentemente con MS sulle stesse curve, ottenuta correlazione e proporzionalità tra le misure. Inoltre, sono stati rilevati gruppi di esami con caratteristiche cliniche simili.

Durant de longues années, la stabilité dans le paradigme d'architecture a facilité la portabilité de performance des grands codes en Calcul de Haute Performance d'une génération à l'autre de supercalculateurs.L'effondrement programmé de la loi de Moore - qui règle les progrès en gravure des micro-processeurs - bouscule ce modèle et requiert un effort nouveau du côté logiciel.Une modernisation des codes basée sur une algorithmique adaptée aux futurs systèmes est ainsi nécessaire.Cette modernisation repose sur des principes de base connus tels que la concurrence des calculs et la localité des données.Cependant, la mise en œuvre de ces principes dans le cadre d'applications réelles en milieu industriel – lesquelles applications sont souvent le fruit d’années d’efforts de développement - s’avère bien plus compliquée que ne le laissait prévoir leur simplicité apparente.Les contributions de cette thèse sont les suivantes :D’une part, nous explorons une méthodologie de modernisation de codes basée sur l’utilisation de proto-applications et la confrontons à une approche directe, en optimisant deux codes de simulation dévéloppés dans un contexte similaire.D’autre part, nous nous concentrons sur l’identification des principaux défis concernant l’adéquation entre applications, modèles de programmation et architectures.Les deux domaines d'application choisis sont la dynamique des fluides et l'électromagnétisme
For many years, the stability of the architecture paradigm has facilitated the performance portability of large HPC codes from one generation of supercomputers to another.The announced breakdown of the Moore's Law, which rules the progress of microprocessor engraving, ends this model and requires new efforts on the software's side.Code modernization, based on an algorithmic which is well adapted to the future systems, is mandatory.This modernization is based on well-known principles as the computation concurrency, or degree of parallelism, and the data locality.However, the implementation of these principles in large industrial applications, which often are the result of years of development efforts, turns out to be way more difficult than expected.This thesis contributions are twofold :On the one hand, we explore a methodology of software modernization based on the concept of proto-applications and compare it with the direct approach, while optimizing two simulation codes developed in a similar context.On the other hand, we focus on the identification of the main challenges for the architecture, the programming models and the applications.The two chosen application fields are the Computational Fluid Dynamics and Computational Electro Magnetics

Texte intégral
Résumé :
Autoclaved aerated concrete is a building material with good thermal insulation properties, which it receives through the pore structure. The production of autoclaved aerated concrete consists of two phases. In the first stage, a porous structure is formed by the reaction of calcium hydroxide and aluminum powder to form hydrogen. In the second stage, the lime and siliceous components react under hydrothermal conditions to form crystalline calcium hydrosilicates which form a binder component in the material. In this paper, the degree of crystallization of calcium hydrosilicates is studied depending on the quantity and fineness of the admixture of the fireclay waste. The effect of three different sizes of the specific surface of the fireclay waste on the microstructure and physico-mechanical properties of the autoclaved aerated concrete was monitored. At the same time, the influence of sand substitute for waste was monitored. The amount of the substitute was 10%, 30% and 50%. Finally, the influence of the fireclay waste admixture on the autoclaved aerated concrete porous structure was assessed. The microstructure was analyzed by X-ray diffraction. Based on the achieved values, it can be said that the admixutre of fireclay waste has a positive effect on the crystallisation of calcium hydosilicate phases. Fireclay waste substitution is possible up to 50%. With a higher amount of substitution, the increasing pressure of autoclaved aerated concrete compression is monitored.

Résumé :
Calcium silicate composites are a widely used building material, especially autoclaved aerated concrete or sand-lime bricks. The physico-mechanical properties of these materials depend on their microstructure. Microstructure is characterized by the content of crystalline calcium silicate compounds that arise during autoclaving. This is in particular the tobermorite mineral, which carries the mechanical strength of the composite. This paper focuses on the influence of secondary raw materials on properties and microstructure of the calcium silicate composite. Secondary raw materials were selected as slag from the combustion of lignite and ground glass. Mixtures of composites were selected with respect to the required C/S molar ratio of 0.73. The hydrothermal treatment was carried out at a temperature of 190 °C and a residence time of 4, 8 and 16 hours. The microstructure of calcium silicate composites and autoclaved aerated concrete was studied. The use of slag resulted in an increase in the intensity of the diffraction line of tobermorite by X-ray diffraction analysis as well as the use of glass. The difference was particularly evident in the shape of the tobermorite crystals. Long strong crystals were detected in the sample with slag, while the sample with glass exhibited low tobermorite leaves. Porous structure of autoclaved aerated concrete with slag was uniform, unlike samples with glass. Both materials have a positive effect on the increase in compressive strengths of the samples.

Texte intégral
Résumé :
Un fantasma recorre el pensamiento político de la izquierda, el fantasma de la soberanía. Sobre su validez se construye un debate central en torno a la idea de pueblo, patria, democracia y satisfacción de derechos. Y su abordaje refleja una pareja contrapuesta de problemas.El más elemental, y de calado teórico, refleja la crisis de los "grandes relatos" y, por extensión, de legitimación fuerte del modelo político representativo. Está crisis, característicamente postmoderna, supone la erosión de los fundamentos del sujeto político moderno. Y el desafío del mismo desde propuestas pluralistas que, como hace Negri, ofrece una impugnación general y teóricamente consistente de los presupuestos del Estado Moderno. La subjetividad de la multitud, si acaso esto no es un contrasentido, se despliega en paralelo al modelo moderno de soberanía e inaugura un régimen político de construcción colectiva y administración del conflicto completamente ajeno a la unidireccionalidad del poder soberano.Esta posición, sin embargo, no agota la vitalidad del problema contemporáneo en torno a la soberanía. De hecho, desde un eje diferente radicalmente diferente y, tal vez, más práctico y orientado a materialidad de la política, la soberanía se viene problematizando como la única clave para dotar de contenido al proceso de reivindicación y ampliación de derechos dentro del marco nacional en un contexto institucional claramente postnacional. Según los defensores del modelo "soberanista" no sería tanto la modernidad, como abstracción fundamental, lo que se habría quebrado, sino el único marco posible de reivindicación y satisfacción de derechos. A ojos de Fusaro, por señalar a su portavoz más abiertamente polémico, solo dentro de las fronteras nacionales y desde la subjetividad hegemónica tiene sentido la reivindicación democrática (poniendo en cuestión la validez política de la diversidad y del cosmopolitismo).El contraste entre ambos marcos es doblemente instructivo: en primer lugar, porque sirve para tomar el pulso de la actualidad de pensamiento que se sigue reclamando dentro de la tradición marxista. En segundo lugar, porque ilustra un escenario práctico para la izquierda política que funciona en direcciones contrapuestas.En esta ponencia nos proponemos estimular ese contraste, señalar sus horizontes (sobre todo los que se diluyen en el ruido de un debate) y poner a prueba la validez teórico-práctica, esto es, la potencia emancipadora, de ambas aproximaciones.

Abstract. Research is devoted to the possibility of obtaining a composition based on a microdispersed ash additive and a plasticizer. Waste from sewage sludge ash used. They are formed at thermal power plants. Such ashes are distinguished by the presence of a large amount of organic matter and a low calcium content. Therefore, they are rarely used in construction. The activation of the waste fuel and the use of a plasticizer can improve the performance of cement compositions with the inclusion of sewage sludge ash.

Résumé :
Las concreciones carbonáticas de tipo septaria objeto del presente estudio se localizan en las proximidades de Tortuero (Guadalajara), en el flanco noroeste (NO) de un sinclinal tumbado en el límite entre el Dominio nororiental del Sistema Central Español y la Cuenca de Madrid. Las concreciones se encuentran en facies mixtas correspondientes a la Capa de Margas de Alcorlo (Turoniense Medio, Cretácico Superior). Esta unidad pertenece a la Mesosecuencia I del Cretácico Superior y corresponde a un máximo regresivo. La metodología empleada para la caracterización mineral y textural ha permitido inferir un posible modelo genético para explicar el origen de estas concreciones carbonáticas. Las concreciones presentan dos formas: una esferoidal y otra discoidal, con diversos tamaños. En su interior se reconocen dos zonas, una interna caracterizada por la presencia de silt (limo) y carbonato (calcita) y una externa de micrita peloidal microbiana, con porosidad secundaria de tipo shrinkage (septarias). Esta porosidad estáparcialmente rellena de un cemento fibroso de calcita. Se deduce que las concreciones se desarrollaron por debajo de la interfase sedimento-agua en un ambiente palustre asociado a la línea de costa. La interrupción de la sedimentación favoreció el crecimiento concrecionar entorno a un núcleo no determinado/visible a partir de aguas continentales freáticas. El origen de las septarias se relaciona con procesos de deshidratación del sedimento por desecación y cementación posterior, característicos de ambientes palustres.

Résumé :
This open file reports geochemical data for stream and groundwater samples collected around the Casino porphyry Cu-Au-Mo deposit, one of the largest and highest-grade deposits of its kind in Canada. The calc-alkaline porphyry is hosted in a Late Cretaceous quartz monzonite and associated breccias in the unglaciated region of west central Yukon. Water chemistry around the deposit was investigated because: (i) the deposit has not yet been disturbed by mining; (ii) the deposit was known to have metal-rich waters in local streams; and (iii) the deposit has atypically preserved ore zones. Stream water samples were collected at 22 sites and groundwater samples were collected from eight sites. Surface and groundwaters around the Casino deposit are anomalous with respect to Cd (up to 5.4 µg/L), Co (up to 64 µg/L), Cu (up to 1657 µg/L), Mo (up to 25 µg/L), As (up to 17 µg/L), Re (up to 0.7 µg/L), and Zn (up to 354 µg/L) concentrations. The stable isotopes of O and H of the groundwaters are essentially identical to the surface waters and plot close to the local and global meteoric water lines, indicating that the waters represent modern recharge, consistent with the generally low salinities of all the waters (total dissolved solids range from 98 to 1320 mg/L). Sulfur and Sr isotopes are consistent with proximal waters interacting with the Casino rocks and mineralization; a sulfide-rich bedrock sample from the deposit has delta-34S = -1.2 permille and proximal groundwaters are only slightly heavier (-0.3 to 3.1 permille). These geochemical and isotopic results indicate that surface water geochemistry is a suitable medium for mineral exploration for porphyry-style mineralization in the Yukon, and similar unglaciated regions in Canada. The atypical geochemical signature (Mo, Se, Re, As, Cu) of these types of deposits are typically reflected in the water chemistry and S isotopes provide a more local vectoring tool.
