L’étude des résidences aristocratiques dans l’ancien comté d’Astarac résulte de travaux réalisés entre 2003 et 2011. Elle s’inscrit dans l’enquête sur les forteresses médiévales de Midi-Pyrénées qui a débuté en 1994 et qui vise à procéder à l’évaluation du patrimoine régional. L’objectif principal a été d’inventorier les différentes formes de fortification liées à la résidence seigneuriale. Le corpus final, composé d’ouvrages de terre fortifiés (mottes, plates-formes et enclos fossoyés), de tours, salles et tours-salles, constitue la base de notre réflexion. Il ressort de cette enquête que le Gers méridional a connu l’implantation d’un grand nombre de fortifications seigneuriales et de résidences aristocratiques médiévales entre le Xe siècle et le XVIe siècle. Près de 320 sites, dispersés sur 10 cantons ont ainsi été répertoriés. Cette étude a été enrichie par le dépouillement des sources écrites disponibles. Un travail historique sur le comté d’Astarac et les seigneurs de cette zone, constituant l’aristocratie locale généralement peu évoquée dans les études analogues, a également été entrepris afin de mieux cerner le statut des propriétaires des habitats fortifiés repérés. Les informations recueillies sur le terrain et dans les sources consultées ont ainsi permis de réaliser un travail de réflexion sur le peuplement et l’organisation du territoire comtal astaracais. / This study of the aristocratic residences of the ancient county of Astarac results from works done between 2003 and 2011. It is part of general survey of the medieval fortresses of Midi-Pyrénées which started in 1994 and aims at evaluating the patrimony of this region. The main purpose was an inventory of fortresses such as mottes, castral platforms, moated sites and ringworks and so aristocratic residences as towers, salas and towers-salas. It shows that the southern part of the Gers department witness the implantation of a number of fortified sites seigniorial and aristocratic residences between the X century and the XVI century. A list of more 320 sites, scattered over 10 cantons was thus drawn up. This work has been completed according to examinations of written documents. An historic work of the ancient county of Astarac and the seigniorial power has been realized to identify proprietary’s statute. Informations from field researches and archival sources made possible an assessment of the populating and the county’s organization.

Les processus érosifs constituent la cause majeure des ruptures des ouvrages hydrauliques comme les digues ou les barrages en terre. Ils touchent également de nombreux ouvrages comme les remblais d'infrastructure de transport ou les fondations de piles de ponts. Les phénomènes d'érosion sont des processus complexes qui dépendent de multiples paramètres. Il est donc indispensable de les caractériser au travers d'essais dédiés. Deux mécanismes principaux d'érosion sont généralement distingués sur les ouvrages linéaires en terre : l'érosion interne et la surverse. La dispersivité du sol est également un facteur important dans ces processus. Le présent travail étudie ces phénomènes à l'aide de trois dispositifs expérimentaux : l'essai d'érosion de trou (HET « Hole Erosion Test ») qui étudie l'agrandissement d'un canal circulaire par analogie à l'érosion interne (érosion de conduit), l'érodimètre à jets mobiles (MoJET « Mobile Jets Erosion Test ») qui érode la surface du sol par des jets perpendiculaires avec des analogies à l'érosion de surface et l'essai d'émiettage amélioré (ECT « Enhanced Crumb Test ») qui évalue le potentiel de désagrégation d'une texture de sol en absence de sollicitation mécanique. Dans une première partie, nous nous sommes intéressés à développer et améliorer ces trois dispositifs expérimentaux, leur protocole d'essai ainsi que leur interprétation pour une application plus pertinente sur les ouvrages. Ainsi, pour le HET, une nouvelle méthode d'interprétation indépendante de l'hydraulique de l'écoulement est proposée. Le dispositif a également été adapté pour réaliser des essais sur des éprouvettes peu perturbées et les plages de sollicitations ont été étendues pour rendre l'essai à la fois applicable sur des sols très résistants et sur des sédiments très sensibles à l'érosion. Le dispositif de MoJET a été utilisé pour effectuer des campagnes d'essais sur ouvrages pilotes avec un mode opératoire révisé. Enfin, le dispositif d'essai d'émiettage a été amélioré pour effectuer un suivi temporel quantitatif de la désagrégation du sol dans l'eau et un protocole a été défini pour la réalisation d'essais sur les sols reconstitués ou prélevés. Dans une seconde partie, les différentes méthodes d'expérimentation ont été appliquées sur deux études pratiques. La première étude porte sur l'utilisation de chaux pour traiter les sols utilisés dans les ouvrages hydrauliques. Nous montrons au travers de campagnes d'essais en laboratoire et sur ouvrages pilotes que l'utilisation d'un tel traitement diminue considérablement la sensibilité à l'érosion des sols traités. La seconde étude porte sur l'influence de la salinité de l'eau (environnante ou constitutive du sol) sur les phénomènes d'érosion et de dispersion. L'utilisation des différents essais a permis de discuter l'influence de plusieurs paramètres et de caractériser le comportement des sols face aux différents aspects des processus érosifs / Erosion Erosion processes are the major cause of failures in hydraulic earthworks such as levees and earth dams. They affect as well many structures including transport infrastructure embankments or foundations of bridge piers. Erosion phenomena are complex processes depending on multiple parameters. It is therefore essential to characterize them through direct measurements. Two principal mechanisms of erosion are generally distinguished on earthworks: internal erosion and overtopping. Dispersivity of the soil is also an important factor in these processes. The present work studies these phenomena using three experimental devices: the Hole Erosion Test (HET), which examines the enlargement of a circular channel simulating internal erosion (piping), the Mobile Jets Erosion Test (MoJET) that erodes the by jets perpendicularly to soil surface by analogy to surface erosion and the Enhanced Crumb Test (ECT) which quantifies the disintegration potential of a soil texture in the absence of mechanical loads. In the first part, we were interested in developing and improving these three experimental devices, their testing protocol and interpretation methods for a more relevant application on earthworks. Thus, for the HET, a new interpretation method independent of the hydraulic flow is proposed. The device has also been adapted to perform tests on undisturbed soil samples and the ranges of stresses have been extended to make the test applicable from highly sensitive sediments to highly resistant soils. The MoJET device was used to perform series of tests on problematic earthworks with a revised procedure. At last, the Crumb Test has been enhanced to perform quantitative monitoring of disaggregation of soil specimens in water and a protocol has been defined for conducting tests on reconstituted or undisturbed soil specimens. In the second part, the different test methods were applied to two practical studies. The first study focuses on the application of lime treatment to hydraulic earthworks. It has been found through series of tests in the laboratory and on experimental earthworks that the application of such treatment technique reduces significantly the sensitivity to erosion of soils. The second study examined the influence of water salinity (pore water or eroding/permeant water) on erosion and dispersion. The use of different tests led to discuss the influence of several parameters and characterize the behavior of soils in various aspects of erosion processes

In 1992 and 1993 the Archaeological Resources Management Service (ARMS) of Ball State University in conjunction with the Upper White River Archaeological Society (UWRAS) conducted limited research of Windsor Mound located in Randolph County, Indiana. The project consisted of obtaining accurate profiles of an amateur excavation that began in 1986 and backfilling the excavation. This thesis provides a synthesis of the previous studies on Windsor Mound, an analysis of the materials recovered and the results of the limited UWRAS/ARMS excavations. / Department of Anthropology

I have organized this paper into four chapters: "The Environmental Situation," "Space and Place," "Art and the Natural Environment," and "Creating Work of My Own." Chapter 1 explains human beings' intrinsic interconnection to the natural environment, outlining why humans should be concerned about the current degraded state of the natural world. Chapter 2 discusses the concepts of space and place. It analyzes how human beings interact with and experience spaces, developing their sense of place - within physical, theoretical, and spiritual realms. It finally illustrates the importance that spaces and places have in humans' lives. Chapter 3 describes the Land Art phenomenon: its development, the different forms within it, and artists producing Land Artworks. The forms and artists included are those that have been inspirational for the development of my own work. It also emphasizes Land Art as a fundamental form for improving humans' relationship with the natural environment and the new realm of eco-feminism that resonates with Land Art ideals. Chapter 4 recounts the development of my art throughout my college career. It describes my work as site-specific, sculptural installations that use natural materials. It also states why this format is the most effective for my senior art thesis project. Focusing mainly on "Ecological Reawakening: organic DNA," it explains the mentality in designing, creating, installing, and completing the work. Overall, Chapter 4 emphasizes the work's two main goals: to demonstrate a new avenue for comprehending humankind's place within earth's environmental spaces, and to advocate for an environmental paradigm shift during the twenty-first century. Finally, Chapter 5 describes the transformation of "Ecological Reawakening: organic DNA" as it developed over time during the spring honors senior thesis course. It details my mentalities in adding living plant matter to the structure, incorporating a stool into the piece, and creating "Evolution," the digital photography composition that documents "Ecological Reawakening" and was included in the Scripps Senior Art Exhibition in the Ruth Chandler Williamson Gallery from May 1 – May 17, 2009.

This thesis on the topic of Technology verification in the field of wheel excavators and its excavations in the first general part deals with the analysis of the work carried out on the construction site. Wheel excavator analysis tools have been developed and used. The study included ?wheel excavators and the technical parameters and analysis with the binding on the size category of wheel excavators?. The second part of the work deals with the evaluation of the results of the data collection for the determination of the actual times of working wheel excavators; and resultant cycles, depending on the work carried out. In addition, there are factors that affect the intended performance wheel excavators and how it works in the implementation of specific operations. Part of the work is the determination of the values of the correction coefficients for the calculation of the actual performance and the determination of the actual wheel excavators, and subsequent analysis of the excavators? performance dependent upon carried out working operations. In conclusion, on the results gained from the analytical process, proposals and guidelines for the optimal use of wheel excavators within the construction industry have been attained.

Urban development demands on construction aggregates are set to rise dramatically over the coming years within the Stockholm region and a significant environmental challenge will be associated with the large flows of construction aggregates and excavated materials in and out of future development projects respectively.   Material banks receive construction and demolition waste (CDW), process this waste and supply recycled aggregates to the construction industry helping to reduce the demand on natural construction minerals.  The transportation of these material flows between the material banks and development areas is predominantly by road in the Stockholm region.  With the transport sector responsible for almost one third of green-house-gas (GHG) emissions in Sweden, there is a motivation for investigating the environmental benefits of minimising transportation distances of construction aggregates.  Quantities of CDW in the form of excavated granular soil and rock from future development locations within a case-study area comprising three municipalities; Botkyrka, Huddinge and Haninge, in the south of Stockholm, have been estimated based on their municipal comprehensive plans up to the year 2030.  This has been done with the assistance of an earthworks estimation tool, the ESAR model, developed by Ecoloop AB.  Distances between existing and planned material banks and future development areas together with the estimated material quantities have been combined to approximate total vehicle-kilometres for the transportation of these materials under a business-as-usual scenario up until 2030.  A comparison has been made to an alternative scenario of strategically located material banks within the case-study area, whereby a methodology has been developed within this study to strategically locate material banks utilising GIS software ArcMap together with land availability map layers for siting material banks previously developed under a separate related study.  In comparison to the business-as-usual scenario, one strategically located material bank within the case-study area reduces total material haulage distances of excavated granular soils and rocks from development areas to the material banks by approximately 42% or 3.67 million vehicle-kilometres, equating to a reduction of 3478 tonnes of CO2e throughout the time horizon of this study.  Another output from the ESAR model is the estimated construction aggregate demand for sub-surface earthworks backfilling activities.  A material flow analysis for the strategically located material bank indicates that the material bank is able to satisfy the sub-surface backfilling construction aggregate demand in the form of recycled aggregates throughout its operation.  Considering the flow of recycled aggregates back to development areas for backfilling earthworks activities, a total combined reduction of 45% or 5.54 million vehicle-kilometres of material haulage distance is achievable, equating to a saving of 5248 tonnes of CO2e.  Reductions in GHG emissions from strategically located material banks are likely to also be significant beyond the boundaries of this study and warrant further research.

The main objective of my thesis was to project a design of a concrete chosen section of the cycling trail in the vicinity of the village of Kamenný Újezd, which is located in Southern Bohemia, south-west of České Budějovice. I propose two alternative cycling trails in accordance with the applicable standards, laws and technical conditions. A better alternative in terms of transport, economy, ecology and aesthetics, I elaborated to the phase of documentation for the notification of the construction of road according to Decree 104/1997 Sb.. In the project, I propose a direction solution, vertical solutions, width layout, road construction, earthworks, drainage, equipment and traffic signs. I analyzed property relations in the proposed cycling route and existing bicycle trails in the given locality. I suggested a cycling communication, which is multifunctional, therefore not only used by cyclists but also pedestrians, in-line skaters, and when appropriate, for occasional agricultural transport.
