Повний текст джерелаRiver dynamics involves complex feedbacks between channel morphology, water flow and sediment transport. The aim of this work is to understand these feedbacks for gravel bed rivers, in which morphology channel is entirely controlled by bedlaod transport. In the first part, we investigated the influence of flow regime on the river morphodynamics and showed that the latters are primarily driven by the interaction between morphology and bedlaod transport, and that flow regime is only secondary. We confirmed this for different scales from the evolution of the longitudinal profile to the grain scale. The second part of this work was devoted to investigation of bedforms in order to understand the coupling between morphology and sediment transport. In particular, our results show the importance of a relaxation effect, i. E. Sediment flux does not immediately adapt to varying topography. This relaxation effect is an important physical parameter to describe the morphology-transport interactions in a river and it is now being recognized as an important effect controlling the developpment of bedforms. However, despite its importance, the majority of bedload transport laws proposed in the literature ignore this relaxation effect. Theses laws implicitly consider particle flux to be in equilibrium with the shear stress. In order to overcome this limitation, in the third part of this work, we focused on the physical origin of this relaxation effect and how to develop a model of bedload transport which accounts of this effect. To do this, we studied the bedload transport at the grain scale through an experimental investigation and analysed the experimental results within the frame of the erosion-deposition model proposed by Charru (2006)

Повний текст джерелаFor a long time, the relations between communication networks and castral sites have been associated with seigniorial taxation (tolls) or military activities (by stopping the trafic). Nevertheless, the coordination of roads, rivers, waterways and castles make appear many dynamic relationships between territories, their economic, political or social organization. The decisive question is to integrate these new perspectives into a representation of the practice of territories to define the real conditions of interrelationship between castral sites and communication networks during the end of the early medieval period and the late Middle Ages. The geographical framework of this thesis, the Lot valley from its source to its confluence, on a course of 485 kilometers (301 miles), allows us to consider the reciprocal permanence of social and spatial relations characterized by a plurality of political groups and struggles of influence between individuals. These different powers (great territorial princes, modest lordships, oligarchy and local aristocracy), whose seigniories and castral domains obtrude along this river, can make spaces, politics, societies and economy interact together to explain the dynamic phenomena that relate to the road, river and castles of the territories observed. This study is enriched by the analysis of archives collected, in nine departmental archive repositories, at the National Library of France (BnF), at the national archives of France or at the Public Record Office of London. This historical work focuses on the various actors of power bordering the Lot and their instruments of land domination in order to understand their logic of power and territorial management regardless of their social rank

Повний текст джерелаThis dissertation examines the evolution of law in Red River (Assiniboia) through the systems, ideas and events that informed the inhabitants’ concepts of rights, from the colony’s creation until its entry into the Canadian Confederation (as the province of Manitoba). Assiniboia was founded in 1811 in the unsettled Indian Territories which were used as hunting grounds by fur-trading companies, who developed the codes and practices of a lex non scripta on-site to regulate social norms, trade and competition. In the 1820s, the District of Assiniboia came under the management of the Hudson’s Bay Company and was placed under its jurisdiction, and, until the late 1860s, it was the only settlement of the western interior to have its own government and institutions. By looking at the legislative and judicial records of the district, the narratives, correspondence and journals composed by settlers, missionaries and rulers of Red River, this dissertation studies the uses of the law as a form of symbolic violence and a normative tool in the social context of the colony. This study contends that, half a century after its creation, Assiniboia was a hybrid legal space ruled simultaneously by customary and institutional law. It demonstrates the population’s active role in its own governance, and the gradual establishment of a legal pluralism that recognized and respected Red River’s multicultural society, one composed of French and English speaking settlers, Amerindians, and a majority of semi-nomadic people of mixed descent. Ultimately, this study highlights the fundamental role played by the Métis and their Native background in all of the changes to the territory’s legal system

Повний текст джерелаThis research provides a history of the relationship between political parties, trade unions and intellectuals from mid Fifties to late Sixties (1956-1967) that focuses on the making of intellectual connections that gave birth to some of the most important reviews of the Italian New Left: «Ragionamenti», «Officina», «Quaderni Rossi», «Classe operaia», «Quaderni Piacentini. Special relevance is accorded to philosophical issues as the renewing of a Marxist perspective and the Italian reception of Lukács and of the Frankfurt School as well as to the major topic of the debate on literature: the question of neo-realism, the new links between industry and literature, populism in contemporary Italian literature, and criticism of cultural industry. Great part of the work consists in an analytical account of Italian political and social history. Some chapters focuses on political matters as the growing of class-struggle and strikes in early Sixites, the economical crisis of ’63-’64, the strategies and the alliances made respectively by the Communists and the Socialists, from the soviet invasion of Hungary to the international struggles of late Sixties (In Vietnam, in Latin America, Africa and with the widespreading of civil rights movements in the West). Some chapters are dedicated to a specific intellectual personality or to a particular book. Raniero Panzieri, socialist leader and founder of «Quaderni Rossi», Franco Fortini, who wrote two deeply influencing books: Dieci Inverni and Verifica dei poteri, Renato Solmi and Cesare Cases of whom is studied the work of diffusion of German philosophy, Asor Rosa and Mario Tronti that are at the origin of Italian workerism with their works Scrittori e popolo and Operai e Capitale. The questions of the political limits and conditions of the intellectual intervention in class-struggle and the role of culture in a neo-capitalist society can be considered the general frame of the entire work.

Повний текст джерелаMany rivers worldwide have seen vegetation establish within their beds throughout the 20th century. In the case of managed rivers, this trend is usually linked to direct geomorphological alterations (sediment mining, diking, etc.) as well as anthropic alterations of flow regime and sediment supply. These pressures have stabilized river beds, allowing vegetation to establish permanently. This vegetation increases the risk of flooding by decreasing flow velocities and increasing water levels. In addition, the associated reduction in availability of pioneer habitats characteristic of these stabilized environments typically degrades biodiversity. Managing hydrology in a way that would limit vegetation establishment on bars presents an interesting management option. In this context, our study was aimed at understanding the impacts of floods of varying magnitude on vegetation removal, as well as identifying and quantifying the underlying mechanisms. This work focused on the Isère River, a heavily managed gravel bed river located in the western French Alps.Vegetation removal was studied at the reach scale using hydrological data, aerial photographs, and topographic data available between 1996 and 2015. At the bar scale, field monitoring before and after floods from april 2014 to september 2015 allowed us to document the impact of floods on sediment mobility and vegetation. A 2D numerical model was used to document fine scale hydraulics.At the reach scale, we found a strong correlation between water volume flowing through the river channel and the amount of vegetation removal. Discharges with return intervals of less than one year seem to have an impact on vegetation removal. The main mechanism observed from aerial photographs was lateral erosion; surface processes were negligible in comparison. However, global vegetation removal was modest: since 1996, on average 3,4 % of vegetated area was removed annually. At the bar scale, our study period permitted monitoring of a series of high frequency floods (return interval < 1 year) and a 10-year food event. Only the largest flood partially removed pioneer vegetation from bars. Young vegetation removal occurred through four different mechanisms: 1) uprooting by surface scour > 20 cm, 2) burial under a thick layer of coarse sediments > 30 cm, 3) uprooting by a combination of surface scour and sediment deposition resulting in no net topographic change, and 4) lateral erosion of bars. Vegetation removal was always associated with significant sediment mobility.We conclude that on the Isere River a very important flood is required to remove vegetation by mobilizing bar surfaces. In contrast, high but not exceptional flows (return interval < 1 an) are capable of removing vegetation through lateral erosion. However, artificial floods alone are unlikely to maintain the full width of the channelized bed of the Isere River free of vegetation. In the future, vegetation removal needs to be studied in the context of alternate bar dynamics with or without vegetation. It seems necessary to consider sediment transport as well as hydrology to understand the overall dynamics of the bed

Повний текст джерелаField and laboratory investigations indicate that gravel bed rivers with poorly-sorted grain size distribution and low lateral confinement, such as in the case of multi-thread, braided and transitional rivers but also wandering single-thread rivers, can simultaneously present active channel variations, both in the planimetric and altimetric directions, together with planimetric and vertical sorting.Actually channel adjustments present a complex interaction with sorting processes. transport and depositional processes of heterogeneous sediment mixtures induce the formation of various sorting patterns, among which free migrating patches such as sorting waves also known as bedload sheets. Such sorting waves are mainly observed by the alternation of bands of finer and coarser material in the streamwise direction.This PhD research investigates the sorting processes of a bimodal grain size distribution both in the lateral and in the vertical direction, with particular focus on the study of bedload sheets.The main aim of this work is to investigate the effects of lateral confinement on river bed morphodynamics and in particular on grain sorting processes; and besides, given that grain sorting plays a crucial role in affecting longitudinal river profile, as well as sediment patterns and bed forms, being indeed the connection between bed topography and bed sediment composition close, we would like to provide simple theoretical analyses and tools able to predict morphodynamic bed river variations driven by sortingDifferent methodologies are applied to successfully achieve this purpose.Firstly, a deep investigation of the state of knowledge of mixed-size sediment morphodynamics, sorting processes, sorted sediment patterns and bedload sheets is carried out.Then, a 1D linear stability analysis of a uniform flow above an erodible bed composed by a bimodal mixture of sediments is performed and investigation of the associated eigenvectors, amplitude of perturbations and migrations rate is discussed. Results are presented in terms of arising instabilities dominated by sorting. Although the monodimensional shallow-water framework, the simple flow model adopted allows for the formulation of an algebraic eigenvalue problem that can be solved analytically, allowing for a deep insight into the mechanisms that drive instabilities.Then, small scale flume experiments are carried out by reproducing three different flow confinement configurations and involving a bimodal mixture of natural sediments. All the configurations show large fluctuations of parameters characterising bed system in terms of bed sediment composition, slope, active channel width and sediment transport rate. The analysis of such parameters allows defining feedbacks among morphological variables. Results of such investigations shed light on the role of lateral confinement on sorting processes and morphodynamics of barebed rivers

Повний текст джерелаCurrently, the Loire river, sees its geodynamic increasingly deteriorated. The deficit of sediment transport causes erosion of the bed on several areas of the basin. This results in a gradual destabilization of structures (dams, bridges), erosion or clogging of banks or a decline in piezometric level alluvial.Treating these problems requires a better understanding of the processes of erosion and river incision, the second succeeding the first, once the alluvial material of the bottom was completely removed, revealing a bed outcrop.This complex phenomenon is currently found in various parts of the Loire river, in the plain of Forez.We propose three approaches for this analysis.The first approach is based on numerical modeling using the equations of Barre-de-Saint-Venant, for flow, coupled with the equations of Exner and Meyer-Peter Müller for sediment transport. This monodimensional model allows the simulation of riverbed changement and sediment discharge, right each calculation point of grid mesh.The second approach is mechanistic and consists of determining the rate of marly bedrock incision by a semi-empirical method by the use of two major variables: the total hydraulic power and an abrasion coefficient. The hydraulic power is calculated using a hydraulic model, while the abrasion coefficient is a mechanical property of the marl which is determined from laboratory tests.The third approach is the geochemistry. It consists in determining the provenance of the materials from tributaries and in the main chanel by analyzing their geochemical signatures. This has been the subject of laboratory tests on samples taken across the linear from Grangent to Balbigny.The results obtained show that these independent approaches are complementary and provide both a qualitative and quantitative description of the incision of the Loire river in the study area

Повний текст джерелаPer quanto riguarda il primo Novecento italiano, sulla scorta di quanto affermato da Calvino, la critica letteraria si è solitamente limitata ad esaminare una produzione fantastica di stampo «intellettuale», anziché «emozionale». In realtà, per il nostro paese, è proprio la nascita di svariate riviste di taglio popolare (e dalle larghe tirature) a contribuire alla diffusione d’un racconto fantastico finalizzato alla meraviglia o al raccapriccio del lettore. “La Domenica del Corriere”, oltre ad essere la più venduta, offre un perfetto esempio di come questo tipo di narrativa acquisti sempre più spazio, contribuendo alla creazione di una scuola di autori prolifici, seppur ai limiti del dilettantismo, e proponendo – spesso per la prima volta – le traduzioni a puntate dei romanzi esteri polizieschi, fantastici o semplicemente avventurosi più noti all’epoca. La citazione nel titolo riprende la risposta, all’interno dell’anonima rubrica “Piccola Posta”, fornita a un lettore che aveva inviato un racconto giudicato dalla redazione «troppo semplice». Il "sale", le "droghe", gli "eccitanti" su cui viene posto l’accento, ben esemplificano il favore accordato dalla testata alla narrativa di genere. È in questi anni che, all’interno dei giornali, il fantastico nostrano diviene una specifica e organizzata espressione della cultura di massa, e non una curiosa e occasionale presenza, e “La Domenica del Corriere” ne rappresenta senz’altro il modello più riuscito.

Повний текст джерелаExploratory qualitative study, to analyze the meetings of the Family Health Strategy team, considering the Pichonian reference of an operational group. It was sought to characterize this practice regarding the organizational and logistic aspects, touching on certain points, and also to identify the aspects that dynamize and create obstacles in group dynamics, based on the look of the team. The data were collected in May-August 2007, in a municipality of the state of Rio Grande do Sul, using the Non-Participant Direct Observation Techniques and Focus Groups. Five meetings conducted by the team according to a protocol were observed, and five Focus Group meetings were held. Two Family Health Strategy teams participated in the study, characterized as a double team, with 18 individuals, including: nurses, physicians, dentists, nurse technicians, dental office assistants and community health agents. The material was organized as proposed by Minayo (2007) and the pichonian perspective of an operational group was adopted to analyze it. The preliminary results of observation were the triggers for the Focus Group sessions and all the results were grouped into three thematic lines: characterization of team meetings regarding the organizational and logistic aspects, dynamizing aspects and those of obstacles to group dynamics, and a few insights to break down the stereotype. For the participants, the team meetings are seen as important meetings spaces with a view to the collective construction of day-to-day work. However, the practice adopted focused on responding to technical issues, touching on aspects related to the group process, a condition considered essential for team work in the Family Health Strategy. From the standpoint of the subjects, the aspects of organization and logistics of the team meetings were not considered relevant, although they lack a certain amount of care, especially when establishing the agenda, recording the minutes and meeting duration. Difficulties in expressing ideas and presenting contrary opinions emerged as obstacles in the group dynamics, indicating that adopting a critical attitude led to segregation from the group, showing that the main weaknesses were associated with the process of team relations. At the end, a few insights favored awareness, and thus the illusion of a “perfect team” was shown not to be true, with a gradual recognition that this concept was rather a matter of idealization than of reality, proper. In a participatory movement with the subjects 13 themselves, it was identified that the team had to be instrumented to manage aspects related to the group process, considering that knowledge on the referential of an Operational Group might contribute to the work involving groups, since this is currently an initiative that has become a tendency of health care work. Thus, getting to know and managing to identify the main phenomena present in the field of groups allows the teams to conduct their meetings in an operational form, considering not only the results , but above all the process used by the subjects until the task is fulfilled, with a view to group learning.
Estudio exploratorio, cualitativo, con el objetivo de analizar las reuniones de equipo de la Estrategia Salud de la Familia, desde el referencial pichoniano de grupo operativo. Puntualmente, se buscó caracterizar esa práctica con relación a los aspectos organizacionales y logísticos, bien como identificar a los aspectos dinamizadores y obstaculizadores de la dinámica grupal, a partir del punto de vista del equipo. Los datos fueron recolectados en el período entre mayo y agosto de 2007, en una municipalidad del estado del Rio Grande do Sul, por medio de las Técnicas de Observación Directa No Participante y de Grupos Focales. Fueron observadas cinco reuniones protocolares del equipo y realizados cinco encuentros de Grupos Focales. Participaron del estudio dos equipos de la Estrategia Salud de la Familia, caracterizados como equipo doble, agregando 18 sujetos, entre ellos: enfermeros, médicos, dentistas, técnicos de enfermería, auxiliares de consultorio dentario y agentes comunitarios de salud. El material fue organizado según propone Minayo (2007), siendo adoptada la perspectiva pichoniana de grupo operativo para análisis del mismo. Los resultados preliminares, oriundos de la observación, se constituyeron en los disparadores de las sesiones del Grupo Focal y los resultados, en el conjunto, fueron agrupados en tres ejes temáticos: caracterización de las reuniones de equipo en cuanto a los aspectos organizacionales y logísticos, aspectos dinamizadores y obstaculizadores de la dinámica grupal y algunos insights para romper con la estereotipia. Para los participantes, las reuniones de equipo son comprendidas como importantes espacios de encuentro con vistas a la construcción colectiva del trabajo cotidiano. Sin embargo, la práctica adoptada se centraba en la atención a cuestiones técnicas, pasando al lado de los aspectos relacionados al proceso grupal, condición considerada necesaria al trabajo en equipo, en la Estrategia Salud de la Familia. Según la óptica de los sujetos, los aspectos de organización y logística de las reuniones de equipo no fueron considerados relevantes, sin embargo carecían de ciertos cuidados, especialmente en la elaboración de la pauta, en la utilización del libro-acta y en el tiempo de duración de las reuniones. Dificultades de expresar ideas y emitir opiniones contrarias emergieron como obstáculos en la dinámica grupal, indicando que la condición de adoptar una postura crítica llevaba a la segregación del grupo, apuntando que las 11 principales fragilidades estaban asociadas al proceso relacional del equipo. Al final, algunos insights favorecieron la toma de consciencia y, así, se desveló la ilusión de “equipo perfecto”, ocurriendo gradual reconocimiento de que esta concepción permanecía más en el plano de la idealización que, propiamente, de la realidad. En un movimiento participativo con los propios sujetos, se identificó que había necesidad de instrumentación del equipo para manejar aspectos relacionados al proceso grupal, considerando que el conocimiento acerca del referencial de Grupo Operativo podría contribuir para el trabajo que envuelve grupos, visto tratarse de una iniciativa que se haya configurado en una tendencia del trabajo en salud actualmente. De ese modo, conocer y conseguir identificar los principales fenómenos, presentes en el campo grupal, posibilitan a los equipos conducir sus reuniones de forma operativa, considerándose no solamente los resultados, pero, sobretodo, el proceso recorrido por los sujetos hasta el alcance de la tarea, con vistas al aprendizaje grupal.

Повний текст джерелаQuesta tesi è dedicata a esplorare gli sviluppi - letterari, editoriali, critici - della fantascienza Italiana a partire dai primi anni Cinquanta fino agli ultimi anni Settanta. Il lavoro si suddivide in tre macrosezioni. La prima, di carattere introduttivo e preliminare, fornisce lo sfondo teorico e storico alle due seguenti. Ho indicato alcuni riferimenti teorici relativamente al concetto di genere e in particolare alla circoscrizione del genere fantascientifico, adottandone una concezione tassonomica, ossia intendendo il genere fantascientifico piuttosto che come un insieme al quale le opere possono appartenere o meno, come un repertorio di topoi e temi tipici, passibili di un riuso stereotipizzato o rifunzionalizzante a seconda delle intenzioni dell'autore. Ho anche cercato di dare almeno in parte conto del complesso dibattito che accompagna il problema definitorio e che si riflette nelle numerose posizioni storiografiche relativamente alle origini del genere e alla sua periodizzazione. Infine una ricostruzione delle vicende della fantascienza in Italia ha offerto l'occasione per tentare di rispondere ad alcune domande fondamentali: ci sono precedenti italiani alla fantascienza del secondo Novecento? Come mai nel secondo dopoguerra la fantascienza viene principalmente importata da altri paesi attraverso le traduzioni dall'inglese e dal francese? Chi ha letto fantascienza in Italia in questi decenni? E, infine, quale è stato il rapporto che la critica letteraria italiana ha avuto con la fantascienza? Il problema dei rapporti tra letteratura fantascientifica e critica ha offerto anche l'occasione di posizionare il presente lavoro nel panorama degli studi esistenti, fornire alcuni rilievi metodologici e motivare la circoscrizione dell'oggetto di studio. Se come momento iniziale del percorso è stato scelto simbolicamente il 1952, anno di nascita delle prime pubblicazioni specializzate e di invenzione del termine “fantascienza”, il termine ad quem del lavoro è invece posto alla fine degli anni Settanta, in virtù del fatto che in un breve torno d'anni vi furono alcuni importanti studi e convegni (il più importante dei quali tenutosi a Palermo nel 1978), che segnarono l'entrata del genere nell'ambito degli studi universitari. Dunque il periodo considerato comprende i primi tre decenni in cui la fantascienza è stata scritta, pubblicata e letta come tale in Italia, ossia con la consapevolezza, da parte degli attori in gioco, di aver a che fare con un genere codificato, dotato di un suo repertorio di topoi e di un suo canone di modelli. Alle principali pubblicazioni specializzate di questi anni è dedicata la seconda sezione: «Urania» di Mondadori (1952-corrente), «I Romanzi del Cosmo» di Ponzoni (1957-'67), la romana «Oltre il Cielo» (pubblicata da Armando Silvestri, 1957-'70), la piacentina «Galassia» (dell'editore La Tribuna, 1961-'79), la romana «Futuro» (edita dalla piccola sigla omonima, 1963-'64), «Robot», pubblicata a Milano da Armenia (1976-'79). Si tratta di riviste o serie periodiche vendute in edicola: la prima fantascienza italiana si presenta come un genere contraddistinto da una vocazione popolare e, almeno inizialmente, assente dalle librerie. Di ciascuna pubblicazione ho ricostruito la storia e la politica editoriale: che tipo di editore la pubblicava, chi ne era il curatore e chi vi collaborava, che tipo di testi - narrativi, critici, informativi, venivano pubblicati e, dunque, che interpretazione ciascuna di esse dava del genere fantascientifico e a che pubblico si rivolgeva. Le fonti adoperate comprendono, oltre alle testate medesime, studi, testimonianze appositamente raccolte e carte d'archivio edite e inedite. Le significative differenze che corrono tra questi periodici danno conto di un'ampia serie di concezioni possibili del genere: se la mondadoriana «Urania» si inserisce a pieno titolo nel settore periodici del grande editore industriale con tirature che arrivano a superare le 40.000 copie a numero negli anni Sessanta, tra le altre testate «Oltre il Cielo», rivista in cui la narrativa affianca gli articoli di missilistica e aeronautica, sopravvive soprattutto grazie agli abbonamenti sottoscritti dal Ministero dell'aeronautica, «I Romanzi del Cosmo» non superano le 20.000 copie di tiratura, «Galassia» le 10.000, fino alle 5.000 di «Futuro». Così, mentre «Urania» sosteneva con una distribuzione capillare la politica editoriale dei curatori (Giorgio Monicelli prima, Fruttero e Lucentini in seguito) rivolta un pubblico il più possibile ampio, e «I Romanzi del Cosmo» ne inseguivano i successi presso un pubblico giovane e desideroso di intrattenimento, le altre si rivolgevano piuttosto a nicchie particolari di pubblico. «Galassia» ad esempio, sotto le successive direzioni di Roberta Rambelli, Ugo Malaguti, Vittorio Curtoni e Gianni Montanari, offriva agli appassionati più raffinati le tendenze recenti e sperimentali della fantascienza internazionale e vantava traduzioni integrali e di qualità; «Futuro», creata da Lino Aldani, Carlo Lo Jacono e Giulio Raiola tentava la via di una fantascienza letterariamente impegnata, e così via. Altrettanto differenziati sono stati gli atteggiamenti di queste pubblicazioni - o meglio: di ciascun curatore - nei confronti degli autori italiani. Svantaggiati dalla concorrenza di una produzione angloamericana cospicua e già pronta da tradurre, gli scrittori italiani che si sono cimentati col genere hanno dovuto fare i conti con le opere tradotte anche in termini di modelli letterari e di repertori tematici consolidati. La relativa ristrettezza del mercato delle pubblicazioni specializzate e le sue periodiche contrazioni non hanno favorito d'altronde la professionalizzazione degli scrittori, che in molti casi si sono rivolti anche ad altri settori del lavoro intellettuale. La seconda e la terza sezione del lavoro ritraggono insomma la fitta rete di legami tra produzione editoriale e produzione letteraria. Proposito in particolare della terza sezione è esemplificare gli esiti di queste dinamiche, attraverso la lettura critica ravvicinata della produzione di tre autori e un'autrice: Lino Aldani, Gilda Musa, Vittorio Curtoni e Vittorio Catani. Si tratta di scrittori che hanno esordito sulle pubblicazioni considerate prima, e in molti casi ne sono stati a lungo lettori, collaboratori o curatori. Le opere di questi quattro autori incarnano modi differenti di intendere la fantascienza, come differenti sono i percorsi da cui ciascun autore proviene. Aldani si impadronisce dei meccanismi e dei topoi tipici del genere per dar vita a una narrativa in cui coesistono un'anima avventurosa e una distopica. Musa coniuga elementi tipicamente fantascientifici a una spiccata sensibilità linguistica, adoperando il genere per riflettere sui destini dell'uomo nella modernità e soprattutto per raggiungere un pubblico più ampio di quello delle sue raccolte poetiche. Curtoni sperimenta le tendenze più recenti della fantascienza anglosassone proponendo racconti che guardano a modelli come quelli di Philip K. Dick e James Graham Ballard. Infine Catani offre l'esempio di una fantascienza italiana meno concentrata sulla sperimentazione formale, ma in grado di incorporare elementi tecnologici e scientifici nelle sue tematiche profonde - dal rapporto tra tecnologia e corpo umano al ruolo dell'economia finanziaria nel mondo post-industriale. Nel complesso questi autori dimostrano non solo l'esistenza di una fantascienza italiana, ma l'esistenza di una fantascienza italiana di qualità.

Повний текст джерелаThe overarching objective in fluvial geomorphology is to explain river morphology and its temporal and spatial evolution. The multiplication of studies led to the realization that geomorphic systems are complex and difficult to understand. The observed river morphology is more than the sum of the individual processes which govern them because of the superimposition of process interactions and non-linear feedback loops at multiple scales. In this context, the goal of this thesis is to explore new avenues of research in order to comprehend more accurately the complexity of gravel-bed river dynamics by using methodological and analytical approaches focusing on the interactions between the flow, transport of sediments as bedload and the bed morphology. This orientation of the thesis is in line with the fact that current paradigms in fluvial geomorphology have not succeeded in explaining adequately the natural variability of the sediment transport and its consequences on the river bedforms. Five avenues are developed in the form of articles based on case studies: 1. The study of the scales of variation of the flow allows us to integrate the turbulent flow structures into flow pulsations at larger scales and to potentially improve our understanding comprehension of bedload sediment transport variability. 2. The quantification of the rates of change of the flow magnitude (acceleration /deceleration) during a flood explains as much the variability of bedload transport fluxes as the flow intensity itself. 3. The use of complementary measurement techniques of bedload processes can reveal new river bed dynamics in gravel-bed rivers: the dilation and contraction of the bed resulting from a flood. 4. The investigation of the generally accepted fact that bedload sediment transport is correlated with the intensity of the morphological changes reveals that the two processes do not relate directly due to their different characteristic scales. 5. The systemic approach of river dynamics based on the use of multivariate analytical techniques is better suited for the study of complex linear and non-linear interactions and feedbacks in the evolution of a river channel. This analysis has shown the importance of the recent history of the morphological changes in response to a flood. The conceptual orientation of this thesis results from a deep reflection on the traditional approaches previously used for several decades in fluvial geomorphology. It is based on a single very extensive data set collected during 21 flood events in a small gravel-bed river, Béard creek (Quebec). The experimental protocol aimed at the simultaneity of processes measurements in order to focus the analysis on the interactions between the flow, the channel morphology and the bedload sediment transport rather than on the individual processes, an approach seldom used in fluvial geomorphology. Each chapter reports on a new concept or a new approach making it possible to resolve some of the issues met in fluvial geomorphology. This work has important implications for the understanding of river bed dynamics and fluvial habitats and is a starting point for new developments.

Повний текст джерелаIn gravel-bed rivers, bedload transport is an intermittent process related to many variables of the fluvial system whose prediction is still unreliable. Available models for prediction of bedload transport use mean hydraulics variables and generally do not consider turbulence even if coherent turbulent flow structures in rivers are highly energetic. New approaches to bedload transport investigation can shed light on this very important process in alluvial channels. In this thesis, we document these components of the fluvial system in a gravel-bed river during a flood. The objectives of the research are to: 1) investigate the effect of discharge on turbulent variables and turbulent coherent flow structures, 2) investigate the effect of discharge on bedload transport events statistics detected with a newly developed and tested algorithm and 3) link turbulent flow characteristics to individual bedload transport events. Turbulence data shows that at high water level, the decelerated flow has a low coherency and an isotropic turbulence where coherent turbulent flow structures have a short duration. These observations differ from those made at low water level where the accelerated flow corresponds to what is generally observed in uniform flows of gravelly channels. Frequency distributions of bedload transport events variables (mean bedload transport rate, event duration and time interval between successive bedload events) have different shapes for the two investigated flood intensity. At high water level, bedload transport is less intermittent that at low discharge where distributions are more characterised by rare events. Flow velocity acceleration on a short time scale has a positive effect on bedload transport, but mainly when the mobilizing flood is under bankfull stage. Results from the study show that turbulence properties and complex relationships between turbulence and bedload transport are a function of discharge.
