Abstract:

The frequency with which individuals do not develop their third molars, or wisdom teeth, is increasing worldwide. This current topic of human evolution is relevant to the research of anthropologists, geneticists, dentists, and other researchers involved in the study of human dentition. Many explanations have been offered to account for the prevalence of molar agenesis including, evolutionary, environmental, and genetic theories. The purpose of this research project is to determine the frequency of third molar agenesis and investigate the relationship between third molar agenesis and maxilloman

Abstract:

Un'architettura software è erosa (o degradata) se mostra una progressiva perdita di integrità strutturale a causa di violazioni dei principi di progettazione. I sistemi erosi soffrono di Architectural Technical Debt (ATD), lo sforzo aggiuntivo richiesto agli sviluppatori per gestire i difetti causati dall'erosione. Un sintomo dell'accumulo di ATD è la presenza di Architectural Smells (AS), decisioni di software design che hanno un impatto negativo sulla qualità interna del sistema software. I sistemi affetti da AS soffrono di maggiori costi di manutenzione e sono più difficili da evolvere. Que

Abstract:

The Kohistan arc, situated in the northwestern Himalaya of North Pakistan, is a Cretaceous intra-oceanic island arc which was erected during subduction of the Tethys Ocean consequent on the northward flight of India. Following accretion to the Asian margin, the arc behaved as an Andean-type continental arc prior to the collision of India with the Asian continent, which uplifted the arc and tilted it, thus providing a unique opportunity to study a complete succession of rocks from the very earliest stages of arc evolution.

Abstract:

The Tyrone Igneous Complex of Northern Ireland forms an integral part of the Grampian-Taconic orogen, linking the well documented sectors of Scotland, western Ireland and Newfoundland. The orogen records the accretion of a series of peri-Laurentian affinity arcs, ophiolites and microcontinental blocks to the Laurentian margin between the Late Cambrian and Middle Ordovician. The Tyrone Igneous Complex is broadly divisible into two distinct units: the c. 484-480 Ma ophiolitic Tyrone Plutonic Group and the structurally overlying c. 475-469 Ma arc-related Tyrone Volcanic Group.

This study concerns the evolution of electrical contact erosion in low voltage 42V DC (24A) applications. The aim is to describe the erosion mechanisms of a single arc discharge at both contact surfaces during operation. To this end the experiments conducted are designed to produce results that enable close examination of the surface profile changes, volumetric contact material movements, and relative quantities of metallic and gaseous species in the arc discharge. The experimental procedure is arranged so that the contacts undergo a low number of operation cycles in order to limit the cumulat

From the four core, 124 samples were retrieved and analyzed for major and trace elements. Two main rock types were identified: FAB and boninite. FAB is a Mid-Ocean Ridge Basalt (MORB)-like tholeiite with variable fluid mobile element enrichment such as Rb, Ba, and Sr, and low Ti/V ratios more similar to an island arc volcanic than a mid-ocean

Soufriere of St. Vincent is the most active subaerial volcano in the Lesser Antilles arc, and is composed of basalts and basaltic andesites. Eruptive style has tended to alternate between predominantly effusive and explosive, although magma compositions show no systematic variations with time. New Ar-Ar and 14C dates help to constrain the geological evolution of the (- 0.6 Ma) volcano. Parental, possibly primary, magmas at Soufriere had MgO contents exceeding 12 wt.% (mg# 75) and were probably nepheline-normative.

Coral terrace surveys and U-series ages of coral and mollusk shells yield a surface uplift rate of ~0.6 m/ka for Kisar Island. The small island is located NE of Timor in the active Banda Arc of Indonesia. Based on this rate, Kisar first emerged from the ocean as recently as ~450 ka. Terrace surveys show warping that follows a pattern of east-west striking folds, which are along strike of thrust-related folds of similar wavelength imaged by a seismic reflection profile just offshore. This deformation shows that the emergence of Kisar can be attributed to forearc closure along the south-dipping

Les archives géologiques sont souvent difficiles d'accès ou bien simplement mal préservées à cause de déformations importantes. Le bassin avant arc d'Hawke Bay de la marge Hikurangi en Nouvelle-Zélande constitue un objet d'étude privilégié. En effet, il est peu déformé, partiellement émergé et actif pendant le Pléistocène, période au cours de laquelle l'âge des séries sédimentaires et certains facteurs comme le climat et l'eustatisme sont bien contr

Abstract:

Petrographic and age analysis of sandstones, detailed structural analysis and gravity modeling were conducted to investigate the origin of the Gondwana Sequence in the Timor Region, and to better constrain the tectonic evolution of the active Banda Arc. Our field studies and U/Pb zircon age analysis helped assign most units to either Asian or Australian affinity. Detrital zircon from uplifted Banda forearc units (Asian affinity) have U/Pb ages as young as 80 Ma (Standley and Harris, in press). In contrast, analysis of detrital zircon from Gondwana Sequence sandstones accreted to the Banda Arc

Abstract:

Cette thèse cible l'évolution Néogène de la branche sud de l'arc alpin occidental. Une approche multi-méthodes associant études de terrain, sismotectonique et thermochronologie basse température y met en évidence un régime tectonique complexe ainsi qu'une évolution morphologique et structurale originale au sein de l'arc. La fracturation s'organise autour d'un faisceau d'accidents NW-SE, à jeu principalement dextre, accompagnant la courbure de l'arc et commandant structure et morphologie. Par ailleurs, à l'échelle des massifs, une structuration en failles normales conjuguées NE-SW traduit une e

Abstract:

The Palaeoproterozoic evolution of the central Outer Hebrides can be explained by modern plate-tectonic processes and is consistent with the products of a Wilson cycle. Local continental crust comprising c. 2.8 Ga tonalitic orthogneiss underwent extension and rifting leading to the deposition of clastic sediments derived from a late Archaean source, and was followed by the emplacement of c. 2 Ga mafic dykes. The latter are probably not directly equivalent to the Scourie dykes of the Scottish mainland. Rupturing and the formation of an ocean basin followed, and this was subsequently subducted a

Full text

Abstract:

The amalgamation of the Central Asian Orogenic Belt in the southwestern Tian Shan in Tajikistan is represented by tectono-magmatic-metamorphic processes that accompanied late Paleozoic ocean closure and collision between the Karakum-Tarim and Kazakh-Kyrgyz terranes. Integrated U-Pb geochronology, thermobarometry, pseudosection modeling, and Hf geochemistry constrain the timing and petro-tectonic nature of these processes. The Gissar batholith and the Garm massif represent an eastward, along-strike increase in paleodepth from upper-batholith (similar to 21-7km) to arc-root (similar to 36-19km)

Abstract:

L’orogène de collision du Zagros appartient aux chaînes Alpines et résulte de la convergence entre l’Arabie et l’Eurasie et de la disparition de la Neotéthys. Cette longue histoire de convergence s’est traduite notamment par la subduction océanique, depuis la fin du Trias – début du Jurassique, l’obduction d’une lithosphère océanique au Crétacé supérieur, puis la collision, au Tertiaire, et le raccourcissement qui se poursuit aujourd’hui. Afin de mieux contraindre l’évolution géodynamique du Zagros, cette étude s’est focalisée sur son enregistrement par les unités de la plaque supérieure, dite
