Predicting trabecular bone microdamage initiation and accumulation using a non-linear perfect damage model

Studies evaluating the mechanical behavior of the trabecular microstructure play an important role in our understanding of pathologies such as osteoporosis, and in increasing our understanding of bone fracture and bone adaptation. Understanding of such behavior in bone is important for predicting and providing early treatment of fractures. The objective of this study is to present a numerical model for studying the initiation and accumulation of trabecular bone microdamage in both the pre- and post-yield regions. A sub-region of human vertebral trabecular bone was analyzed using a uniformly loaded anatomically accurate microstructural three-dimensional finite element model. The evolution of trabecular bone microdamage was governed using a non-linear, modulus reduction, perfect damage approach derived from a generalized plasticity stress-strain law. The model introduced in this paper establishes a history of microdamage evolution in both the pre- and post-yield regions

An analysis of Ibn al-'Arabi's al-Insan al-Kamil, the Perfect Individual, with a brief comparison to the thought of Sir Muhammad Iqbal

This thesis analyzes four philosophical questions surrounding Ibn al-'Arabi's concept of the al-iman al-kamil, the Perfect Individual. The Introduction provides a definition of Sufism, and it situates Ibn al-'Arabi's thought within the broader context of the philosophy of perfection. Chapter One discusses the transformative knowledge of the Perfect Individual. It analyzes the relationship between reason, revelation, and intuition, and the different roles they play within Islam, Islamic philosophy, and Sufism. Chapter Two discusses the ontological and metaphysical importance of the Perfect Individual, exploring the importance of perfection within existence by looking at the relationship the Perfect Individual has with God and the world, the eternal and non-eternal. In Chapter Three the physical manifestations of the Perfect Individual and their relationship to the Prophet Muhammad are analyzed. It explores the Perfect Individual's roles as Prophet, Saint, and Seal. The final chapter compares Ibn al-'Arabi's Perfect Individual to Sir Muhammad Iqbal's in order to analyze the different ways perfect action can be conceptualized. It analyzes the relationship between freedom and action.

Violence, sexualité et double : les représentations féminines dans Perfect Blue et Paprika de Kon Satoshi

Le présent mémoire consiste en une analyse thématique des représentations féminines dans l’œuvre de Satoshi Kon, de Perfect Blue à Paprika. L’objectif de ce travail est de démontrer que ces images de la femme reflètent la place des femmes dans la société japonaise contemporaine. À cet effet, nous avons examiné les films du réalisateur selon l’approche des études féministes du cinéma. Nous avons divisé notre analyse en trois thèmes : la violence, la sexualité et le double. Il apparaît que les représentations féminines des longs-métrages de Kon possèdent effectivement des parallèles au sein la société nippone actuelle. Le réalisateur emploie des figures et des motifs narratifs communs au Japon et l’anime afin de produire et reproduire les stéréotypes de genre. Par ailleurs, il utilise les éléments filmiques et les particularités du médium de l’anime pour appuyer ces définitions des rôles sexuels. Cette étude est originale par son angle d’approche féministe et psychanalytique qui est rarement adopté par les théoriciens de l’anime. Les études portant sur ce médium sont d’ailleurs récentes et s’intéressent généralement à l’esthétique de l’anime ou à la formation d’une identité nationale japonaise plutôt qu’à la construction du genre dans un média de culture populaire.

Problemas conceptuales en el aprendizaje de segundas lenguas : la adquisición del present perfect simple para los hablantes de español : un caso paradigmático.

Esta investigación intenta facilitar la comprensión del proceso de aprendizaje de una segunda lengua y los posibles mecanismos del lenguaje involucrados, a partir del problema concreto de la adquisición del 'present perfect simple' en inglés para los hablantes del español.. El trabajo consta de dos partes centrales. La primera, dedicada a los fundamentos teóricos en los que se apoya el estudio, y la segunda, dedicada a un aproximación empírica, en donde se realizan varios estudios con distintos tipos de materiales que ponen a prueba las hipótesis de partida. Se formulan dos tipos de análisis con este fin: dos cuestionarios y tres experimentos. Ambos se centran tareas de reconocimiento y de producción del 'present perfect simple' y de sus usos.. Es necesario comprender que las dificultades de aprendizaje de algunos conocimientos, como el uso del 'present simple', radican en su dimensión conceptual, y no en su complejidad sintáctica o morfológica. Por esta razón, La autora considera indispensable comprender la naturaleza de los problemas de enseñanza de segundas lenguas para poder pensar así una práctica concienzuda de la docencia..

Searching for the perfect surface area normalizing term - a comparison of BET surface area-, geometric surface area- and mass-normalized dissolution rates of anorthite and biotite

Dissolution rates were calculated for a range of grain sizes of anorthite and biotite dissolved under far from equilibrium conditions at pH 3, T = 20 degrees C. Dissolution rates were normalized to initial and final BET surface area, geometric surface area, mass and (for biotite only) geometric edge surface area. Constant (within error) dissolution rates were only obtained by normalizing to initial BET surface area for biotite. The normalizing term that gave the smallest variation about the mean for anorthite was initial BET surface area. In field studies, only current (final) surface area is measurable. In this study, final geometric surface area gave the smallest variation for anorthite dissolution rates and final geometric edge surface area for biotite dissolution rates.

Evaluating the potential for statistical decadal predictions of sea surface temperatures with a perfect model approach

We explore the potential for making statistical decadal predictions of sea surface temperatures (SSTs) in a perfect model analysis, with a focus on the Atlantic basin. Various statistical methods (Lagged correlations, Linear Inverse Modelling and Constructed Analogue) are found to have significant skill in predicting the internal variability of Atlantic SSTs for up to a decade ahead in control integrations of two different global climate models (GCMs), namely HadCM3 and HadGEM1. Statistical methods which consider non-local information tend to perform best, but which is the most successful statistical method depends on the region considered, GCM data used and prediction lead time. However, the Constructed Analogue method tends to have the highest skill at longer lead times. Importantly, the regions of greatest prediction skill can be very different to regions identified as potentially predictable from variance explained arguments. This finding suggests that significant local decadal variability is not necessarily a prerequisite for skillful decadal predictions, and that the statistical methods are capturing some of the dynamics of low-frequency SST evolution. In particular, using data from HadGEM1, significant skill at lead times of 6–10 years is found in the tropical North Atlantic, a region with relatively little decadal variability compared to interannual variability. This skill appears to come from reconstructing the SSTs in the far north Atlantic, suggesting that the more northern latitudes are optimal for SST observations to improve predictions. We additionally explore whether adding sub-surface temperature data improves these decadal statistical predictions, and find that, again, it depends on the region, prediction lead time and GCM data used. Overall, we argue that the estimated prediction skill motivates the further development of statistical decadal predictions of SSTs as a benchmark for current and future GCM-based decadal climate predictions.
