Résumé :

L’oggetto di questa tesi è stato lo studio della mineralogia dei sedimenti fluviali ed eolici attuali generati dall’erosione della catena Himalayana, con lo scopo di definire con precisione le segnature composizionali dei diversi domini tettono-stratigrafici dell’orogene. All’approccio basato sulla identificazione e quantificazione delle associazioni di minerali pesanti (densità > 2.90 g/cm3), sono stati affiancate diverse tecniche analitiche complementari, che comprendono la petrografia e la geochimica del sedimento totale, lo studio di dettaglio al microscopio elettronico a scansione e allo

Résumé :

Relying on computing systems that become increasingly complex is difficult: with many factors potentially affecting the result of a computation or its properties, understanding where problems appear and fixing them is a challenging proposition. Typically, the process of finding solutions is driven by trial and error or by experience-based insights. In this dissertation, I examine the idea of using provenance metadata (the set of elements that have contributed to the existence of a piece of data, together with their relationships) instead. I show that considering provenance a primitive of compu

Résumé :

The Datalog programming language has recently found increasing traction in research and industry. Driven by its clean declarative semantics, along with its conciseness and ease of use, Datalog has been adopted for a wide range of important applications, such as program analysis, graph problems, and networking. To enable this adoption, modern Datalog engines have implemented advanced language features and high-performance evaluation of Datalog programs. Unfortunately, critical infrastructure and tooling to support Datalog users and developers are still missing. For example, there are only limit

Résumé :

Traditionally, an archival fonds is conceptualized as an aggregate of records which are mutually relevant. This mutual relevance is often attributed to the origin of member records in a common context – with this context typically understood as the context of an organization, and more specifically, a department. It is considered difficult to identify mutually relevant records in modern organizations. This difficulty is often attributed to frequent administrative changes which disrupt departmental contexts.

Advances in mass spectrometry in the second half of this century allowed very accurate measurements of isotopic compositions of various elements. In turn it was discovered that due to the radiogenic origin of some of these isotopes their composition often reflects the geochemical history of minerals and rocks. Terrestrial lead is composed of four isotopes, of which three are radiogenic in origin as daughters of uranium and thorium. In geochronology the isotopic composition of minerals helps in dating the ore and rock formations. However, if there is enough diversity amongst the isotopic compos

Résumé :

Pleistocene New Jersey shelf sedimentology is strongly influenced by glacially driven sea level changes. A combination of regressive shoreline processes, subaerial exposure, fluvial downcutting, and deposition and reworking during transgression has influenced the NJ shelf sediment composition. Sediment provenance and transport history may be determined on a shelf environment through analysis of grain size distribution, heavy mineral content, magnetic mineral concentrations, and isotopic dating methods. A combination of surface grab and stratigraphic samples were analyzed within the study area.

Sediment petrography and heavy mineral analysis represent two key techniques to decipher the pieces of information stored in the sedimentary record, shedding light on source rocks compositon, weathering conditions and paleodrainages.

L'analyse de la provenance a été faite par des études pétrographiques en grès à cinq coupes stratigraphiques représentatives des séquences considérées appartenant au Crétacé inférieur et au Miocène dans le secteur nord du bassin Austral. D'autres études préliminaires de diffraction des rayons X à un profil (appe

Résumé :

L'obsidienne a été utilisée comme matière première de l'industrie lithique au cours de périodes préhistoriques. Ce matériau possède des propriétés spécifiques qui caractérisent son lieu d'origine. La rareté de ses sources et l'intérêt dont l'obsidienne a fait l' objet par le passé en font pour le préhistorien un marqueur remarquable d'échanges et de contacts humains à grande distance. Nous montrons les avantages relatifs, pour la détermination de la composition chimique, de l'analyse sous faisceau d'ions par PlXE -Particle InducedX-ray Emission-, qui permet des mesures non destructives, et par

Résumé :

The Central Asian Orogenic Belt formed by accretion subsequent to the contraction of the Palaeo-Asian Ocean that ultimately disappeared along the Solonker Suture Zone in East Asia. Since typical regional collisional features are absent, the tectonic evolution of the suture remains speculative. Integrated sedimentary provenance analyses across the accretionary collision zone between the Mongolian Arcs and the North China Craton place new constraints on the events that led to final suturing.

Résumé :

Glass is one of the oldest materials produced and extensively used by man, thanks to its unique mechanical and chemical-physical properties. For these reasons it has a great importance in both archaeological and artistic fields. So far, notwithstanding the essential lines of development of glass production are known, there are still some particular ‘critical moments’ in the history of glass production. In this context the present work investigated the evolution of glass technology in a particular geographical area, the northern Adriatic Italy, which, for its peculiar position, had a central ro

Résumé :

The northern hemisphere plant <i>Arnica montana</i> L. can be found across Europe on high alpine slopes with acidic soils. The flowers are well documented as a source of natural products, particularly, active compounds associated with anti-inflammatory properties. The high demand for this extract has meant that wild plant numbers have reduced dramatically and now in many countries, it is illegal to harvest <i>A. Montana </i>from the wild. As a result, flowers from the non-endangered <i>A. chamissonis</i> Less. Have been employed for the production of extracts with similar properties. <i>A. mon

Résumé :

The Middle Ordovician Ancell Group, including the St. Peter Sandstone, Glenwood Shale and Starved Rock Formation, records intracontinental basin development during eustatic sea level changes in Iowa and Illinois. The St. Peter Sandstone overlies the Prairie du Chien Group across an erosional unconformity that marks a major sequence boundary, whereas upper contact of the St. Peter Sandstone with the Glenwood Shale also is a second sequence boundary. Data from 80 wells, selected well logs, and 20 cores were integrated to refine the high-resolution sequence stratigraphy of the Ancell Group. Two m

Résumé :

L'objectif de cette thèse est de développer et d'analyser des techniques numériques basées sur la méthode e Boltzmann sur réseau (LBM) pour résoudre des systèmes non linéaires de type advection-réaction-diffusion provenant de la physique et de la biologie. Avec la LBM, des problèmes portant sur des quantités moyennées densité, potentiel, vitesse, etc) sont exprimés à l'échelle particulaire. Nous approchons la solution de l'équation e Boltzmann relative au comportement d'un champs de particules puis nous recomposons les quantités moyennées solutions des équations traitées.
