Delta Store #3033 in Indianola, MS is suspected of having had a release of petroleum, which may have contaminated the underlying soil and shallow groundwater. Exploratory boring/monitoring wells were drilled on-site noting all soil formations and groundwater encountered. The soil facies encountered show a fining upward sequence, representative of a fluvial depositional environment. Soil contamination is mostly confined to the surficial soil; however, evaluation of lab data, boring logs, and cross sections suggests it is likely the contamination migrated through the surficial confining layer into the underlying strata. The hydraulic conductivity of 1.2 x 10-5 cm/sec, surficial geology consisting mostly of low and some high plasticity clays (CL and CH), a hydraulic gradient of 0.01 to 0.02 ft/ft, and the presence of an overlying concrete pavement suggests that any recent release of hydrocarbons should be confined to the immediate vicinity under the site.

Chemical Mechanical Polishing, (CMP), pads made of polyurethane material are utilized in the Integrated Circuit, (IC), industry to planarize wafers between successive process steps. The properties of such pads and their behavior must be known in order to determine under what conditions and for how long they can be used efficiently. This research involved the development of a system to study the properties of such pads. The system developed during this research enabled the pads to be tested under varying physical conditions. The setup used a combination of several instruments to provide excitation to the pad and acquire a measure its response. A central computer controlled the instrumentation system employed. In this research the determination of the physical properties of CMP pads was accomplished through the use of Ultra Sound testing. Ultra sound methods offer a non-destructive method of characterizing pads to be used in the production of IC wafers. Ultra sound characterization is currently one of the most widely used techniques utilized for non-destructive inspection. This report provides a detailed account of the hardware instruments involved and the method of integration of those instruments into a system that could easily, rapidly and accurately characterize CMP pads. The pad response was measured in terms of the signal voltage transmitted through the pad to the ultrasound sensor. The software stored these readings for every set of testing conditions. Changing the temperature, humidity and depth from the pad's surface where measurements are made changed the test conditions. These data were analyzed statistically to determine the behavior of the pad. This research was part of a larger research effort that provided the statistical tool required to determine the uniformity of a CMP pad.

La mise en forme à froid des alliages d’aluminium peut être limitée par les transferts de matière sur la surface des outillages pouvant mener au grippage. L’objectif de ce travail de thèse est de contribuer à une meilleure compréhension de ces mécanismes pour permettre à terme d’optimiser les procédés de formage d’un alliage Al-Mg-Si. Une approche couplée expérimentale et numérique est développée afin d’alimenter une base de données d’indicateurs de dégradations des surfaces. L’approche expérimentale développée au cours de ces travaux repose sur l’utilisation de l’essai de compression-translation. Ce dispositif permet de reproduire une large gamme de conditions de contact rencontrées en mise en forme à froid. Une méthode d’analyse des surfaces reposant sur des mesures par profilométrie optique et des analyses au microscope électronique à balayage est développée afin d’évaluer le volume de matière adhérée sur les outils de chaque configuration d’essai. Le comportement rhéologique de l’alliage Al-Mg-Si est caractérisé à l’aide du simulateur thermomécanique GLEEBLE 3500 sur la gamme de températures de 298 à 423 K et à deux vitesses de déformation de 0,1 et 1 s-1. Un modèle de comportement physique reposant sur l’analyse du taux d’écrouissage et l’utilisation du modèle de la contrainte mécanique seuil est développé puis implémenté dans un logiciel éléments finis. Un modèle numérique de l’essai de caractérisation tribologique est développé. Il s’agit d’une analyse thermomécanique utilisant la formulation arbitrairement lagrangienne-eulérienne. Les données locales telles que la pression de contact et la vitesse de glissement calculées par ce modèle permettent de mieux comprendre les mécanismes de collage observés expérimentalement. Enfin, un programme de traitement des résultats numériques est développé afin de réaliser les modifications géométriques de la surface de l’outil en fonction du dépôt relevé expérimentalement. Un modèle d’usure basé sur le travail des forces de frottement est identifié. Ce dernier est un bon indicateur de la tendance au collage et permet une première approximation de ce mécanisme. / Cold forming of aluminium alloys can be limited by a severe material transfer to the die surfaces, compromising the process viability. The purpose of this research work is to contribute to a broader understanding of the galling mechanisms which would further allow the optimisation of the forming processes of an Al-Mg-Si alloy. A methodology combining experimental and numerical approaches is introduced in order to build up a database of surface degradations indicators. The experimental approach is carried out by means of upsetting-sliding tests which reproduce a wide range of contact conditions experienced at the tool/workpiece interface during cold forming operations. To evaluate the amounts of adhered material on the tools of each test configuration, surface topography acquisitions are performed by optical profilometry and coupled to scanning electron microscope analyses. Axisymmetric compression tests are carried out by means of the GLEEBLE 3500 thermomechanical simulator to determine the deformation behaviour of the Al-Mg-Si alloy at high strains, in the temperature range of 298 to 423 K and strain rates of 0.1 and 1 s¡1. A constitutive model based on both the Mechanical Threshold Stress model and the analysis of the work-hardening rate is proposed and then implemented in a finite element code. A finite element simulation of the upsetting-sliding test, which is a thermomechanical analysis using the arbitrary lagrangian-eulerian formulation, is introduced. The local contact variables such as the contact pressure and the sliding velocity are evaluated through this simulation and allow a better understanding of the galling mechanisms observed experimentally. Finally, a post-processing program, which analyses the results of the finite element simulation and updates the tool shape according to the amount of adhered material determined experimentally, is developed. A wear model based on the friction work is introduced. This model is a good indicator of the galling tendency and allows a first approximation of this mechanism.

<p><em>With the advent of huge multicore processors, complex hardware, intermingled networks and huge disk storage capabilities the programs that are used in the system and the code which is written to control them are increasingly getting large and often much complicated.

Ce mémoire porte sur l’utilisation des unités sémiotiques temporelles en tant qu’outil compositionnel. Les UST sont définies par François Delalande comme des segments musicaux qui présentent une signification temporelle précise due à leur organisation morphologique. La démarche suivie – axée sur leur emploi à des fins expressives – conduit à une plus consciente maîtrise du phénomène temporel. Par suite d’un renversement de leur fonction conventionnellement analytique, ces unités participent activement au processus poïétique et abordent la condition intérieure du matériau sonore. Les analyses présentées dans ce mémoire suggèrent que la manipulation du temps de l’écoute – lorsqu’elle est fonction des stratégies cognitives de l’auditeur – constitue une partie importante de l’expérience esthétique. Ainsi, les UST peuvent représenter une ressource puissante au service d’une communication musicale efficace. / This thesis investigates the use of temporal semiotic units in music composition. Temporal semiotic units have been defined by François Delalande as musical segments that possess a precise temporal signification linked to their morphological organization. This research focuses on how their descriptive function can be exploited as a mean for music composition, contributing to the overall aesthetic and expressive qualities of music. By reversing their conventional analytical function, these units can actively engage in the poietic process, addressing the inner conditions of the sound material. The artistic research outlined by this thesis suggests that a thorough control of time – which relates to the cognitive strategies of listening – plays a powerful role in shaping the musical experience of the listener. Therefore, these units can represent a useful resource for effective communication in music.

Bakgrund: Knäskador är vanligt förekommande bland yngre fysiskt aktiva personer. Ofta skadas flera strukturer samtidigt vilket medför att den mekaniska stabiliteten i knäleden försämras samt att den neuromuskulära funktionen i benet försämras, vilket påverkar den posturala kontrollen samt stabiliteten på knät. För att upptäcka instabilitet behövs mer utmanande och specifika test som Star Excursion Balance Test (SEBT). I dagsläget saknas studier gjorda med SEBT på en svensk population. Fysioterapeuter är beroende av tillförlitliga instrument för att kunna göra en korrekt bedömning. Syfte: Syftet med studien var att undersöka test-retest reliabiliteten för SEBT samt att undersöka samtidig validitet mellan SEBT och Unilateral Stance test (UST) för personer med knäproblematik.Syftet var dessutom att undersöka hur den posturala kontrollen var för personer i åldrarna 20-30 år med knäproblematik mätt med SEBT och UST. Metod: Studien var gjord med en icke experimentell design som var både deskriptiv och korrelerande. Alla tester gjordes vid ett tillfälle med 5 minuters vila mellan testerna. I studien ingick 30 personer med diagnostiserad alternativt självupplevd knäproblematik i åldern 20-30 år som studerade på Biomedicinskt centrum vid Uppsala Universitet. Resultat: Den posturala kontrollen för testpersonerna (n=30) var uppmätt till god både mätt med både SEBT och UST. Validiteten mellan SEBT och UST var låg r=0,3 (p=0,12). Test-retest reliabiliteten för SEBT var god r=0,74 (p=0.00013). Konklusion: SEBT har en god interbedömarreliabilitet. Korrelationen mellan UST och SEBT var låg. SEBT är ett test som är ett väldigt specifikt test där man behöver både material och tid för utförandet. Det behövs mer studier för att få fram om testet går att användas effektivt på allmänna kliniker som ett utvärderingsinstrument för postural kontroll.

Changing patterns of marital and reproductive behavior of young women in the urban settlement (on the example of Ust-Kamenogorsk, East Kazakhstan oblast, Kazakhstan) Abstract This study primarily addresses nuptiality and fertility patterns among youth in East Kazakhstan region. The data are obtained from censuses, vital statistics and two surveys "Marital and reproductive behavior of young women in Ust-Kamenogorsk" conducted in 2009 and 2016. The survey data collection has been supported by Center of International programs of Kazakhstan "Bolashak" and Charles University in Prague. The thesis examines demographic behaviours of two main ethnicities (Kazakh and Russian) in East Kazakhstan oblast and influence of such factors like ethnicity, education, place of residence and socio- economic conditions on their marital and reproductive behaviour. East Kazakhstan oblast, compared with other regions of Kazakhstan, has lower birth and marriage rates, higher divorce rates, higher share of non-native ethnicities residing in urban areas and higher proportion of female workers employed in the industrial sector. The author tries to evaluate the importance of marriage to young females and its relation to their reproductive and marital behaviour. The general tendency observed from the conducted survey was that young women...
