Abstract:
Surface pasting is an interactive hierarchical modelling technique used to construct surfaces with varying levels of local detail. The concept is similar to that of the physical process of modelling with clay, where features are placed on to a base surface and attached by a smooth join obtained by adjusting the feature. Cylindrical surface pasting extends this modelling paradigm by allowing for two base surfaces to be joined smoothly via a blending cylinder, as in attaching a clay head to the body using a neck. Unfortunately, computer-based pasting involves approximations that can cause cracks to appear in the composite surface. In particular this occurs when the pasted feature boundary does not lie exactly over the user-specified pasting region on the base surface. Determining pasted locations for the feature boundary control points that give a close to exact join is non-trivial, especially in the case of cylinders as their control points can not be defined to lie on their closed curve boundary. I propose and compare six simple methods for positioning a feature cylinder's control points such that the join boundary discontinuities are minimized. The methods considered are all algorithmically simple alternatives having low computational costs. While the results demonstrate an order of magnitude quality improvement for some methods on a convex-only curved base, as the complexity of the base surface increases, all the methods show similar performance. Although unexpected, it turns out that a simple mapping of the control points directly onto the pasting closed curve given on the base surface offers a reasonable cylindrical boundary pasting technique.

Includes bibliographical references (leaves 21-22).
Clinical documentation by physicians and nurses has struggled to evolve with advancing technology and societal requirements. Originally designed as a physician's personal notes for a patient, the modern medical record functions as a patient record, communication tool between providers, and instrument for financial reimbursement. Technology has played a pivotal part in advancing the role of the medical record. Advantages and disadvantages inherent in the introduction of each new technology have prompted much debate, but none more than the introduction of electronic documentation systems within electronic medical records. Electronic systems provide clear advantages of information exchange as well as decision and diagnostic support. They have also proven quite controversial, particularly in the initial implementation stages. One aspect of electronic documentation, electronic copying and pasting, provides a tool for the clinician that is not clearly beneficial or detrimental, with proponents on each side. In this paper we explore the social, economic, and legal issues surrounding electronic copying and pasting in clinical documentation, review the literature on this subject, and propose a model for future research in this topic to help shape how clinicians use and process patient information from multiple sources.

Abstract:
The physicochemical, morphological, pasting and softening kinetics of rice varieties selected from West-African countries were investigated. The studies conducted were aimed at enhancing the adoption and use of these local varieties in improving food security in Africa through the development of acceptable new rice-based products .The varietal, morphological and physiochemical impacts on appearance, pasting, textural properties and softening kinetics were also analyzed. To unravel structural properties of the respective isolated rice starch from the selected rice varieties, scanning electron microscopic analysis was also carried out. The varieties studied were Faro 61, Faro 60, Faro 44, Tox 3145 and Nerica 3. Microscopic studies carried out on the isolated starch indicated that the starch granules were 4.43 -5.62 µm. The structural variations observed did not clearly provide an explanation for the pasting and textural properties of the studied rice varieties. Morphological studies also revealed that the rice granules were polyhedral, irregular in shape and tightly packed. Proximate studies indicated that the rice varieties were composed of 0.35 - 0.52% fat, 0.32 - 0.57% ash , 8.97 - 10.35% protein, 88.63 - 90.08% carbohydrate and 22.4 - 28.50% amylose. The proximate results indicates that these varieties are high protein containing waxy rice varieties. Color parameters (L*and b*) studies of uncooked rice flour samples indicated high values of L* and low values of b* for all the rice varieties. The order of increasing whiteness was found to be Faro 61 > Faro 44 > Faro 60 > Nerica 3 > Tox 3145 while the b* values ranged from 5.09 - 7.26. The high degree of whiteness and low values of yellowness of these rice varieties indicate that their flours would be highly acceptable by most consumers. Results of the pasting properties studies indicated significant differences in the peak viscosity , trough viscosity, final viscosity and set back viscosity of the rice flours. Faro 44 showed a higher peak viscosity value (3984.5 cP) while Nerica 3 indicated the lowest peak viscosity value (2850.5 cP). Faro 44 and Tox 3145 had the highest and lowest trough viscosities, respectively. Break down viscosities were within the 546.5 and 1164 cP range for the rice varieties. Faro 44 had significantly higher breakdown viscosities than other varieties. The result indicated that Faro 44 flour is suitable for the production of value added products such as noodles, due to the ability of its paste to swell sufficiently while remaining intact and stable during sheering. Setback viscosity varied from 865.5 to 2138.5 cP. Faro 44 showed the highest setback viscosity (2138.5 cP) while Faro 61 showed the least (865.5 cP). The pasting temperature of Faro 44 was higher than the other rice varieties and found to be 85.50C. Textural studies indicated hardness decreased with increase in cooking time. When cooked from 5 minutes to 25 minutes, there was gross disintegration of the rice granular structure . These structural changes provide an explanation for the corresponding changes in the tissue strength and elasticity of the studied rice varieties. In addition, the rate of textural changes related with the cooking temperature utilized in this study was found to confirm with two pseudo first-order kinetic mechanisms. The kinetic model utilized indicated that the apparent rate constants K1 a varied from 0.03776 to 0.4468 min-1 while K1 b varied from 0.008475 to 0.013665 min-1 . Over all, variations were observed in the morphological, physicochemical, pasting and softening kinetic properties of all the studied rice varieties. These studies are vital in ensuring an improving quality of rice by thermal processing.
Les variétés de riz étudie étaient Faro 61, 60 Faro, Faro 44, Tox 3145 et Nerica 3. Les observations microscopiques réalisées sur l'amidon isolé ont indique que les granules d'amidon variaient eutre 4.43 et 5.62 µm. Ces variations structurelles n'expliquait pas clairement les propriétés texturales et collantes des variétés de riz étudie. Des études morphologiques ont aussi révélé que les granules d'amidon de riz étaient polyédriques, serre et de forme irrégulière. L'analyse immédiate des macronutriments a révélé que les variétés de riz sont composées de 0.35 à 0.52% de matières grasses, de 0.32 à 0.57% de cendres, 8.97 à 10.35% de protéines, de 88.63 à 90.08% de glucides et, enfin, 22.4 à 28.50% d'amylose. Ces résultats indiquent que ces variétés sont les variétés de riz sont riches en protéines.L'étude sur les paramètres de couleur (L* et b*) des échantillons de farine de riz non cuite indique de valeurs élevées de L* et de faibles valeurs de b* pour toutes les variétés de riz. L'ordre croissant de blancheur a été jugée être Faro 61> Faro 44> Faro 60> Nerica 3> Tox 3145, tandis que les valeurs de b* variaient entre 5,09 et 7,26. Un haut degré de blancheur combine a un faible de jaunissement de ces variétés de riz indiquent que ces farines seraient bien acceptées par la plupart des consommateurs. Les résultats des études des propriétés collantes ont dénoté des différences significatives pour la viscosité maximale, minimale, finale et la viscosité de rechute des farines de riz. Faro 44 a montré une valeur de viscosité maximale élevée (3984,5 cP), tandis que le Nerica 3 indique la valeur du sommet de la viscosité moins grande (2850,5 cP). Faro 44 et Tox 3145 avaient respectivement les plus hautes et les plus basses viscosités minimales. Les viscosités de dégradation se rangeaient entre 546,5 et 1164 cps pour toutes les variétés de riz. Faro 44 avait une viscosité de dégradation nettement plus élevés que les autres variétés. Ce résultat indique que la farine de riz Faro 44 est appropriée pour la production des produits à valeur enrichie, tels que les nouilles, en raison de la capacité de la pâte de gonfler suffisamment tout en restant intacte et stable pendant le cisaillage. La viscosité de rechute varie de 865,5 à 2138,5 cP. Faro 44 a montré la viscosité de rechute la plus élevé (2138,5 cP), alors que Faro 61 a montré la moindre (865,5 cP). La température de gélatinisation de Faro 44 était plus élevée que les autres variétés de riz et établie à 85.5°C. Le etudes texturales ont indiqué que la dureté diminue avec la hausse du temps de cuisson. À la fin du cuisson de 5 minutes à 25 minutes, il y a eu une désintégration brute de la structure granulaire de riz. Ces changements structurels fournissent une explication pour les changements correspondants dans la solidité du tissu et l'élasticité des variétés de riz étudiées. En outre, le taux de changements de texture en rapport avec la température de cuisson utilisée dans cette étude correspond à deux mécanismes cinétiques de pseudo premier ordre. Le modèle cinétique utilisé a indiqué que les constantes de vitesse apparentes K1 a ont varie de 0,03776 à 0,4468 min-1, tandis que K1 b se rangeaient entre 0,008475 et 0,013665 min-1. Ces études sont essentielles afin d'assurer et améliorer la qualité du riz par traitement thermique. Dans l'ensemble, les variations des variétés du riz étudiées ont été observées en tant que leur caractéristiques morphologiques, physico-chimiques, les propriétés de gélatinisation, ramollissement ainsi que les propriétés cinétiques.

Many natural starches do not have specific characteristics for industrial processing. Therefore, these starches are modified in order to give them desirable properties such as texture, appearance, softness, etc. The modifications produced in the starches generally change some of their physical properties, such as pasting temperature, viscosity, viscosity breakage, and retrogradation tendency. Hydrothermal treatments modify the physical and chemical properties of the starches without destroying their granular structure, and do not add other kinds of chemicals to the treated samples; in other words, the starch continues to be natural. Studies indicate that these modifications change the functional properties in respect to resistance to the actions of enzymes present in the high digestive treatment, and thus increasethe concentration of resistant starches. Therefore, one aim of the present study was to assess the effects of annealing and heat-humidity hydrothermal treatments on samples of starch from four varieties of cassava, in respect to pasting resistance and concentration properties. A second aim was to analyze the profiles of the pasting resistance and concentration properties of starches from two varieties of cassava in different stages of development. The cassava starches Fécula Branca, Cascuda, Capora and IAC 576/70, both in natura and modified with the annealing and heat-moisture treatments, were evaluated regarding their pasting and concentration properties of resistant starch. The Fécula Branca and Cascuda varieties, with physiological ages of 10, 11, 12, 13, 14 and 15 months, were analyzed for their pasting and concentration properties of resistant starch.

Abstract:
Ferrets are amusing, flexible creatures that have been under represented in computer models. Because their bodies can assume almost any curved shape, splines are the natural tool for modelling ferrets. Surface pasting is a hierarchical method of modelling with spline surfaces, where features are added onto a base surface. Existing surface pasting techniques are limited to modelling rectilinear shapes. Using the task of modelling a ferret as a driving force, I propose a method of pasting cylinders in world space; I looked at methods for reducing distortion of pasted features; and I created a method for pasting trimmed features to allow for features that do not have the rectilinear shape of standard pasting. With my methods, modelling ferrets with surface pasting is easier, and the resulting models are closer to a real ferret.

To realize the full potential of waxy wheat flours in food applications, six advanced hard waxy wheat lines were studied. Pasting properties of waxy wheat flours as well as factors governing the pasting properties were investigated. Waxy wheat starch granules swelled more extensively and were more prone to α-amylase degradation than normal wheat starch. A combination of endogenous α-amylase activity and protein matrix contributed to a large variation of pasting properties of waxy wheat flours. Bi-axial extension properties classified dough from waxy wheat as in-elastic. Waxy wheat flour had higher water absorption and lower mixing time than normal wheat flour. Waxy wheat starch affected protein hydration but not protein extractability after optimum dough mixing. Presence of some non-protein free thiol contents and some gliadins acting as chain terminators could be the underlying reasons for waxy wheat flours producing slack dough. In an effort to improve functionality of waxy wheat flours, hydro-thermal processing was used. Two temperatures (140 and 160°C), three moisture contents (0, 12.4 and 20%), and four exposure times (0, 5, 15, 30 and 60 min) were employed. Hydrothermal processing resulted in non-cohesive waxy wheat flours with high viscosity and greater acid stability than native waxy wheat flour. A closer investigation revealed the possible role of endosperm proteins in improving pasting properties of waxy wheat flours. Upon thermal processing, waxy wheat flours demonstrated a long hydration time before forming dough. Heating decreased protein solubility while no changes in starch molecular weight distribution were observed. Our results indicate that hydro-thermal processing results in increased starch protein interaction. As part of application of waxy wheat, bread was baked by replacing normal wheat flour with two hard waxy wheat flours at 15, 30, and 45% levels. Substitution with waxy wheat flour resulted in higher loaf volume and softer loaves. However, substitution at > 30% resulted in excessive post-bake shrinkage and a ‘key-hole’ shape with an open crumb structure. Bread crumb microstructure indicated a loss of starch granule rigidity and fusing of starch granules. Soluble starch content was significantly higher in bread 1-day old crumb containing waxy wheat flour than in control bread.

Abstract:
The buckwheat is a naturally gluten-free pseudocereal, rich in phytochemicals, phenols and functional proteins, however, the functional characteristics of its flour in baking process are not as performing as those of wheat flour. The aim of this thesis was to analyse how the functional, viscosimetric and antioxidant properties of two variety of buckwheat (Polish and Italian) flours change in response to an ultrasound (US) pre-treatment carried out on different solid:liquid ratio. For this, in the differently treated Polish buckwheat samples some functional properties (water absorption index, water solubility index, swelling power, water holding capacity, water absorption capacity, foaming capacity and stability, emulsifying activity and emulsion stability) were analysed. Moreover, the thermoviscous test, antioxidant capacity and polyphenol content were quantified. Finally, bread samples, obtained with treated and untreated Polish buckwheat flour were analysed for baking loss, specific volume, colour analysis of crust, porosity and hardness. The obtained results showed that the US pre-treatment increased the water holding capacity, improved the foam stability, but decreased the ability to form foams and emulsions as well as the viscosity of the treated flour samples. The breads formulated with US treated flours had a more uniform pore distribution in the crumb and were softer than the breads formulated with untreated flour. Moreover, US pre-treatment had no effects on surface colour and phenolic content of obtained bread. In conclusion, the application of US on buckwheat flour can be a good alternative to the use of additives in formulation in order to obtain gluten-free and nutritionally rich final products.

Abstract:
O amido é um ingrediente com grande versatilidade de aplicação, e as sementes de jaca, fruto bem difundido, porém pouco aproveitado no Brasil, contêm uma quantidade considerável de amido, sendo ainda fonte de ferro e proteínas. Dessa maneira, os objetivos desse projeto foram a obtenção da farinha de sementes de jaca das variedades mole e dura, a extração do amido utilizando diferentes solventes, e a caracterização de suas propriedades físico-químicas, estruturais e funcionais, bem como a caracterização reológica de dispersões/géis de amido em cisalhamento estacionário e oscilatório. A extração alcalina do amido, além de reduzir significativamente o conteúdo de lipídeos e proteínas, deixando o amido mais puro, promoveu um aumento no teor de amilose e influenciou diretamente as características de inchamento e solubilidade, que apresentaram aumento significativo a partir da temperatura de 70 °C. O aumento da temperatura ocasionou aumento no poder de inchamento e solubilidade, que foi mais pronunciado para a variedade dura, porém esses valores ainda foram considerados baixos (< 17%). Os amidos de sementes de jaca apresentaram grânulos lisos, arredondados e em forma de sino, com formato mais truncado para o amido extraído com hidróxido de sódio. O diâmetro médio dos grânulos de amido foi menor para a extração alcalina, mas sempre com comportamento monomodal. Foi observado um padrão de difração de Raios-X do tipo A para todas as amostras estudadas, e o índice de cristalinidade foi maior para os amidos de sementes de jaca dura, com uma redução estimada em 70% para os amidos obtidos por extração alcalina. A temperatura de gelatinização dos amidos de semente de jaca foi considerada alta (70-100 °C). Os amidos de sementes de jaca dura obtidos na extração com água apresentaram maiores valores de viscosidade de pico e de Breakdown, que representa menor resistência mecânica. A extração com solução de NaOH 0,1 M aumentou a tendência a retrogradação de ~36% (extração aquosa) para 64% e 45% dos amidos de sementes de jaca das variedades mole e dura, respectivamente. Todas as amostras apresentaram comportamento pseudoplástico (n < 1) nas concentrações e temperaturas estudadas, e as dispersões e/ou géis de amido obtidos pela extração alcalina com NaOH apresentaram menor tixotropia e maiores valores de viscosidade. Os modelos Lei da Potência e Herschel Bulkley apresentaram ótimos ajustes aos pontos experimentais (R² ~0,998) para as amostras com 2 e 6 % de amido, respectivamente, porém para a concentração de 5%, o melhor modelo foi função da variedade do fruto usado na obtenção do amido. A dependência das propriedades reológicas com a temperatura foi analisada pela equação de Arrhenius e a energia de ativação foi baixa (15-25 kJ/mol). Quanto ao comportamento viscoelástico, as amostras com 5 e 6% de amido apresentaram comportamento de gel fraco e o aumento da concentração desse polissacarídeo produziu um aumento na elasticidade do material. Os módulos de armazenamento (G\') associados à elasticidade do gel de amido aumentaram durante o seu resfriamento nos ensaios de varredura de temperatura, o que pode ser relacionado à recristalização da amilose durante esse processo e mantiveram-se praticamente constantes no aquecimento isotérmico a 80 °C, sugerindo boa estabilidade térmica do gel. A farinha isolada da semente de jaca pode ser considerada fonte de fibras e apresentou elevados teores de proteínas (~14-16%) e ferro (~85-150 mg/kg). A distribuição do tamanho de partículas da farinha apresentou comportamento bimodal, com grânulos arredondados, presença de fibras e uma matriz proteica envolvendo os grânulos de amido. As propriedades de pasta revelaram maior pico de viscosidade para a farinha de semente de jaca mole. As características encontradas sugerem que os amidos de semente de jaca poderiam ser aplicados na produção de filmes biodegradáveis, e a farinha da semente de jaca poderia ser utilizada em substituição parcial à farinha convencional na fabricação de bolos e biscoitos.
Starch is an ingredient with great versatility of application, and the seeds of jackfruit, a well spread fruit but little exploited in Brazil, contain a considerable amount of starch, being a source of iron and proteins. Thus, the aimes of this project were to obtain the jackfruit seed flour of hard and soft varieties, extraction of starch using different solvents and characterization of its physicochemical, structural and functional properties, as the rheological characterization of dispersion/gels starch under steady and oscillatory shear. Alkaline extraction of starch significantly reduced the content of lipids and proteins, leaving to a purest starch, and promoted an increase in amylose content, besides, directly influenced the swelling and solubility characteristics, which showed a significant increase from the temperature of 70 ° C. The increase in temperature caused an increase in the power of swelling and solubility, which was more pronounced for the hard variety, but these values are still considered low (<17%). Jackfruit seeds starch granules showed smooth, rounded, bell-shaped, and they had more truncated form when starch was extracted with sodium hydroxide. The average diameter of the starch granules was lower for alkaline extraction, but always with monomodal behavior. It was observed diffraction pattern of X-rays of type A for all samples, and the crystallinity index was higher for the starches of hard jackfruit seeds with an estimated reduction of 70% to starches obtained by alkaline extraction. The gelatinization temperature of starches jackfruit seed was considered high (70-100 °C). The hard jackfruit seed starches obtained in the aqueous extraction had higher peak viscosities and Breakdown, what means lower mechanical strength. Extraction with 0.1 M NaOH solution increased the retrogradation of ~ 36% (aqueous extraction) to 64% and 45% of jackfruit seed starch varieties of soft and hard, respectively. All samples exhibited pseudoplastic behavior (n <1) at the concentrations and temperatures studied, and starch dispersions and /or gels obtained by alkaline extraction with NaOH showed lower thixotropy and higher viscosities. Power Law and Herschel Bulkley models showed great adjustments to the experimental points (R² ~ 0.998) for samples with 2 and 6% starch, respectively, but for the concentration of 5%, the best model was a function of the fruit variety used on starch extraction. The dependence of the rheological properties with temperature was examined by the Arrhenius equation and activation energy was low (15-25 kJ / mol). In concern to the viscoelastic behavior, samples of 5 and 6% of starch showed a behavior of weak gel and the increase in concentration of this polysaccharide produced an increase in the elasticity of the material. The storage modulus (G \') associated with the elasticity of the starch gel increased during its cooling in the temperature sweep tests, which may be related to the recrystallization of amylose during this process and remained practically constant in the isothermal heating at 80 °C, suggesting good thermal stability of the gel. The isolated jackfruit seed flour may be considered source of fiber and showed high levels of proteins (~ 14-16%) and iron (~ 85-150 mg / kg). Particle size distribution of the flour showed bimodal behavior with rounded beads, fibers and the presence of a protein matrix surrounding the starch granules. Pasting properties revealed higher peak viscosity for the soft jackfruit seeds flour. The characteristics found suggest that jackfruit seed starch could be applied in the production of biodegradable films, and jackfruit seed flour could be used in partial replacement of conventional flour in the manufacture of cakes and cookies.

Abstract:
Ce travail de recherche vise à évaluer le comportement au fluage de nouvelles structures composites en associant trois matériaux: le bois, le béton fibré ultra-haute performance (BFUP) et des armatures polymères renforcées de fibres de carbone (PRFC). Le but de la conception d'une telle section hybride est de faire usage des meilleures caractéristiques de chaque matériau afin d'augmenter sa capacité portante à l'ultime et/ou en service. Aussi, d'un point de vue du comportement mécanique, cette solution de renforcement vise à apprécier et hiérarchiser l'intérêt d'une telle solution liée aux effets déférés, particulièrement au fluage. La première étape consiste à mener une analyse expérimentale sur le comportement en statique de poutres hétérogènes bois-BFUP. Elle est exécutée afin de mieux comprendre le mécanisme d'endommagement ainsi que la performance pour définir le comportement au fluage. Pour cela, une campagne expérimentale en flexion quatre points portant sur trois poutres, dont une poutre témoin, a été conduite sous sollicitation statique. Les résultats obtenus confirment que les poutres hétérogènes Bois-BFUP apportent une optimisation de capacité portante ainsi que de la rigidité. Les poutres hybrides ont permis d'obtenir le même mode de rupture en flexion et la première rupture s'est produite dans la partie comprimée de BFUP supérieur. La seconde partie de la recherche est consacrée à l'analyse du comportement au fluage de poutres hétérogènes bois-BFUP nécessaire pour prédire les déformations à long terme dans des structures composites hybrides. Dans cette étude, deux types d'essai ont été réalisés : essai en environnement contrôlé et essai en environnement non contrôlé (extérieur). En environnement contrôlé les essais fluage ont commencé sous une charge constante de 24 kN dans le laboratoire avec des températures de 20±5 °C et une humidité relative entre 40% et 60%. Ces conditions climatiques peuvent être considérées comme un environnement de classe 1, conformément à l'Eurocode 5. Les résultats ont montré que la flèche de fluage de la poutre renforcée augmente peu tout au long de l'essai. A l'inverse de ces résultats, l'essai de fluage en environnement variable à l'extérieur du laboratoire, qui peut être considéré comme environnement de classe 3 suivant l'Eurocode 5, montre que les effets différés du bois et du béton jouent un rôle très important dans l'évolution de la flèche finale
This dissertation aims to evaluate the creep behaviour of a new composite structure combined three materials: the wood, the ultra-high performance fibre-reinforced concrete (UHPFRC) and the polymer fibre reinforced carbon (CFRP) according to their advantages and performances. The conception of such hybrid section is to use the best characteristics of each material to increase its bearing capacity in the ultimate and / or in service. Furthermore, from the point of view of design, this strengthening solution is to assess and prioritize the interests to reduce the deformation caused by the delayed effects, particularly caused by creep. The first part investigated an experimental analysis of the static behaviour of the wood-UHPFRC beam, and should be performed to understand the mechanism of the hybrid beam as well as the performance which are the directions to identify the creep behaviour. A four-points bending test setup on three beams, one beam witness, was conducted under static loading. The results confirm that heterogeneous Timber-UHPFRC beams provide an optimization of bearing capacity and stiffness. The hybrid beams have produced the same flexural mode of failure and the first crack occurred in the upper part of compressed UHPFRC. The second part of the research is devoted to the analysis of creep behaviour of heterogeneous wood beams UHPC necessary to predict long-term deformations in composite structures. In this study, two types of test setups were conducted: test in a sheltered and outdoor environment. In the sheltered environment, the creep test began under a constant load of 24 kN in the laboratory with temperatures of 20 ± 5 °C and a relative humidity between 40% and 60%. These climatic conditions can be considered as the service class 1, according to Eurocode 5. The results showed that the creep deflection of the reinforced beam gradually increases throughout the test. Unlike these results, the creep test in a variable environment outside the laboratory, which can be considered Class Service 3 to Eurocode 5, shows that the effect of time dependency behaviour of wood and concrete plays a very important role in the evolution of the creep deflection of the hybrid beams

Abstract:
As a major group of agricultural commodities, legume grains are widely grown and consumed globally, but are often utilised in the whole form. With increasing evidence of nutritional benefits, these grains are potentially sources of novel ingredients including starches. Accordingly the objective of this study has been to investigate legume starches, particularly their isolation, characterisation and incorporation into selected food products. Using chickpea, faba bean, lentil and mung bean, extraction procedures for the practical isolation of legume starches have been evaluated. A relatively simple method has been established, involving grain cracking, steeping in a mildly alkaline solution, followed by washing, double blending, double sieving and sedimentation. The starches collected for the four legumes were oven dried and the recoveries ranged between 29 and 38%. Compositional analyses confirming that the isolation procedure gave relatively pure starches and scanning electron microscopy showed that the granules were typically ellipsoidal. Laser particle size analysis showed mono-modal distributions with mean diameters between 19.6 and 23.9µm. X-ray diffractograms of legume starches were of the typical C-type, with variations in the intensities and peak distribution indicating some differences in the crystallinity of the starches. Suitable conditions for the measurement of starch gelatinisation characteristics by differential scanning calorimetry were investigated. When optimised conditions were applied, the temperature of gelatinisation ranged from 58.9 for lentil to 65.7 °C for mung bean with corresponding enthalpy values of 9.2 and 5.7 Jg-1. Hot-stage optical microscopy confirmed gelatinisation patterns. The starch pastes demonstrated opalescence with some variation in the degree of clarity. The pasting and viscosity properties measured by the Rapid Visco-Analyser showed some variation in pasting temperatures and considerable differences in peak readings with faba bean starch having lowest and mung bean the highest with values of 307 and 676 RVA units, respectively. In order to study the incorporation of the legume starches, two Asian food products having starch as an ingredient, were selected and adapted as model foods. In this context, vermicelli represented a savoury product and coconut cake a sweet product. Vermicelli and coconut cake samples that incorporated chickpea starch were both preferred by most of the panellists over those containing the other legume starches. The overall conclusions are that the starch extraction method adapted in this investigation was a practical approach, producing relatively pure, white starches. The characteristics of the four legume starches showed many similarities, but there were some variations in the properties, indicating that there may be different applications for their incorporation into food formulations. Sensory evaluations confirmed the usefulness of the starches as food ingredients that provide attractive mouthfeel and textural characteristics. Therefore legume starches offer potential as novel food ingredients warranting further evaluation and larger scale feasibility studies.

Abstract:
Les catégories supérieures sont des structures algébriques constituées de cellules de différentes dimensions et équipées d'opérations de composition. Elles ont trouvé plusieurs applications en mathématiques (en particulier, dans le domaine de la topologie algébrique) et en informatique théorique. Ce sont des structures notoirement complexes, dont la manipulation est technique et sujette aux erreurs. Le but de cette thèse est d'introduire plusieurs outils informatiques pour les variantes strictes et semi-strictes des catégories supérieures qui facilitent l'étude de ces objets. Afin de répresenter les catégories supérieures par des données finies, de sorte que ces dernières puissent être transmises comme entrée à un programme, on utilise la structure de polygraphe, initialement introduite par Street et Burroni pour les catégories strictes, et généralisée par Batanin à toute théorie algébrique de catégorie supérieure, qui permet de présenter des catégories supérieures par des systèmes de générateurs. Le premier problème abordé par cette thèse est celui du problème du mot sur les catégories strictes, qui consiste à déterminer si deux composées formelles de cellules d'une catégorie stricte représentent la même cellule. On donne une solution implémentable et relativement efficace pour ce problème en améliorant la procédure de décision initialement donnée par Makkai. Ensuite, nous traitons les formalismes pour les diagrammes de recollement. Ces derniers permettent de représenter efficacement les cellules de catégories strictes en utilisant des structures ensemblistes et pour lesquels une implémentation efficace est désirable. On étudie en particulier les trois principaux formalismes qui ont été introduits jusqu'ici : les complexes de parité de Street, les schémas de recollement de Johnson et les complexes dirigés augmentés de Steiner. Notre étude révèle que les axiomatiques des deux premiers est défectueuse, ce qui motive l'introduction d'une nouvelle structure, appelée complexe sans torsion, dont les axiomes ont de bonnes propriétés et généralisent ceux des autres formalismes. On montre que cette nouvelle structure est adéquate pour représenter informatiquement les catégories strictes en en donnant une implémentation. Pour finir, on considère le problème des présentations cohérentes de structures algébriques exprimées dans les catégories faibles de dimension 3, ces dernières étant connues pour être équivalentes aux catégories de Gray. En s'inspirant d'un résultat important de Squier dans le context des monoïdes, on adapte les résultats classiques de la théorie de la réécriture au contexte des catégories de Gray et relions la cohérence de présentations de catégories de Gray à la confluence de branchements critiques d'un système de réécriture associé. Avec ce résultat, nous déduisons une procédure semi-automatique pour produire des présentations cohérentes de catégories de Gray, et nous l'appliquons sur plusieurs exemples
Higher categories are algebraic structures consisting of cells of various dimensions equipped with notions of composition, which have found many applications in mathematics (algebraic topology in particular) and theoretical computer science. They are notably complicated structures whose manipulation is technical and error-prone. The purpose of this thesis is to introduce several computational tools for strict and semi-strict variants of higher categories that ease the study of these objects. In order to represent higher categories as finite data, so that they can be given as input to a program, we use the structure of polygraph, initially introduced by Street and Burroni for strict categories and then generalized by Batanin to any algebraic theory of higher category, which allows presenting higher categories by means of systems of generators. The first problem tackled by this thesis is then the one of the word problem on strict categories, which consists in deciding whether two formal composites of cells of strict categories represent the same cell. We give an implementable and relatively efficient solution for it by improving the decidability procedure initially given by Makkai. Then, we turn to pasting diagram formalisms for strict categories, which enable to efficiently represent cells of strict categories using set-like structures and for which a reliable implementation is desirable. We consider the three main formalisms which have been introduced until now, namely Street's parity complexes, Johnson's pasting schemes and Steiner's augmented directed complexes. Our study reveals that the axiomatics of the first two ones are defective, which motivates the introduction of a new structure, called torsion-free complexes, whose axioms have nice properties and generalize those of the three other formalisms. We also show that they are amenable to concrete computation, by providing an implementation of those. Finally, we consider the problem of coherence of presentations of algebraic structures expressed in 3-dimensional weak categories, the latter being known to be equivalent to Gray categories. Taking inspiration from a celebrated result given by Squier in the context of monoids, we adapt the classical tools from rewriting theory to the setting of Gray categories and relate the coherence of presentations of Gray categories to the confluence of the critical branchings of an associated rewriting system. From this result, we deduce a semi-automated procedure to find coherent presentations of Gray categories that we apply on several examples

This study was conducted to evaluate the chemical, physical-chemical, biochemical and rheological properties of starch from Solanum lycocarpum. The pulp from Solanum lycocarpum fruits was used as raw material for extraction of starch, resulting in a yield of 51%. The starch granules were heterogeneous in size, presenting a conical appearance, very similar to those from high-amylose cassava starch. The elemental analysis (CHNS) revealed 64.33% carbon, 7.16% hydrogen and 0.80% nitrogen. FT-IR spectroscopy showed the peaks characteristic of polysaccharides and NMR analysis confirmed the presence of the α-anomer of D-glucose. The S. lycocarpum starch was characterized by high value of intrinsic viscosity (3515 mPa s) and estimated molecular weight around 645.69 kDa. Furthermore, this starch was classified as a C-type and high amylose content starch, presenting 34.66% of amylose and 38% crystallinity. Endothermic transition temperatures (To = 61.25°C; Tp = 64.5°C; Tc = 67.5°C), gelatinization temperature (∆T = 6.3°C) and enthalpy changes (∆H= 13.21 J g−1) were accessed by DCS analysis. The thermogravimetric analysis of S. lycocarpum starch showed a typical three-step weight loss pattern. Microscopy revealed significant changes in the granule morphology after thermal treatment. Samples treated at 50°C for 10 min lost 52% of their crystallinity, which was partially recovered after storage for 7 days at 4°C. However, samples treated at 65°C for 10 min became were totally amorphous. This treatment was sufficient to completely disrupt the starch granule, as evidenced by the absence of an endothermic peak in the DSC thermogram. The RVA of S. lycocarpum starch revealed 4440.7 cP peak viscosity, 2660.5 cP breakdown viscosity, 2414.1 cP final viscosity, 834.3 cP setback viscosity, and a pasting temperature of 49.6°C. The low content of resistant starch (10.25%) and high content of digestible starch (89.78%) in S. lycocarpum suggest that this starch may be a good source for the production of hydrolysates, such as glucose syrup and its derivatives. These results make the S. lycocarpum fruit a very promising source of starch for biotechnological applications.
Este trabalho foi realizado para avaliar as propriedades químicas, físico- químicas, bioquímicas e reológicas do amido de Solanum lycocarpum. Polpas dos frutos de Solanum lycocarpum foram utilizadas como matéria-prima para a extração de amido, resultando em um rendimento de 51%. Os grânulos de amido apresentaram tamanho heterogêneo, com aparência cônica, muito semelhante ao amido de mandioca, com alto teor de amilose. A análise elementar (CHNS) revelou 64,33% de carbono, 7,16% de hidrogênio e 0,80% de nitrogênio. A espectroscopia FT-IR revelou picos característicos de polissacarídeos e a análise de RMN confirmou a presença do carbono αanomérico da D-glicose. O amido de S. lycocarpum apresentou elevada viscosidade intrínseca (3515 mPa s) e peso molecular estimado de 645,69 kDa. Além disso, este amido foi classificado como um amido do tipo C, apresentando 34,66% de amilose e 38% de cristalinidade. Através de análises por DCS determinou-se as temperaturas de transição endotérmica (To = 61,25°C; Tp = 64,5°C; Tc = 67,5°C), a variação da temperatura de gelatinização (∆T = 6,3°C) e a variação de entalpia (∆H = 13,21 J g-1). A análise termogravimétrica do amido de S. lycocarpum apresentou um padrão típico de perda de peso de três etapas. A microscopia revelou alterações significativas na morfologia dos grânulos após o tratamento térmico. As amostras tratadas a 50°C, durante 10 minutos, perderam 52% de sua cristalinidade, a qual foi parcialmente recuperada após armazenamento a 4°C, por 7 dias. No entanto, as amostras tratadas a 65°C, por 10 minutos, perderam totalmente sua cristalinidade, apresentando estrutura totalmente amorfa. Este tratamento foi suficiente para romper completamente o grânulo de amido, conforme evidenciado pela ausência do pico endotérmico na curva do DSC desta amostra. O RVA do amido de S. lycocarpum revelou um pico de viscosidade de 4440,7 cP, quebra de viscosidade 2660,5 cP, viscosidade final 2414,1 cP, tendência a retrogradação 834,3 cP e temperatura de pasta de 49,6°C. O baixo teor de amido resistente (10,25%) e o elevado teor de amido digerível (89,78%) sugerem que este amido pode ser uma boa fonte para a produção de hidrolisados, tais como xarope de glicose e seus derivados. Os resultados obtidos neste estudo fazem do fruto de S. lycocarpum uma fonte promissora de amido para aplicações biotecnológicas.

The theme of my thesis is analysis and evaluation of development of wood pastures at several locations in the Elbe lowlands from the first half of 19th century up to the present. The area is characterized by its fertility and the large share of arable land. The data analysis was developed using a geographic information system (GIS). The basic documents were maps and written operate of Stationary cadaster. The results of the work are map compositions depicting the change trajectories of wood pastures (extinct, continuous and new), graphs show the area of individual trajectories and evaluate the utility of written operate of the Stacionary cadastre. We have put the obtained information about the natural and social-economic development of the area into context. We got a possible explanation of development, therefore, why the old wooded pastures vanish and new ones arisen elsewhere. Changes of wood pastures were influenced by socio-economic development of the area and probably by distance from a watercourse. The informations obtained from written operate of Stacionary cadaster are useless for this thesis.

Abstract:
Freshwater ecosystems are extremely important, both socially and ecologically, in Aotearoa/New Zealand. However, through detrimental practices of land-use change and the introduction of non-indigenous aquatic species, the health of freshwater areas is increasingly under threat. Coarse fish are one group of non indigenous fish that are largely perceived to have a negative effect on freshwater biodiversity and water quality. Despite this, there are people in New Zealand that value coarse fish highly, and consider their lives to be enriched through the practice of coarse angling. This thesis examines the diversity of perceptions and values ascribed to coarse fish by a variety of different environmental managers and resource users to understand how these multiple meanings influence approaches to freshwater biodiversity management in Aotearoa/New Zealand. As coarse anglers are often considered responsible for deliberate translocation of coarse fish, a space for communication and compromise between these stakeholder groups is also identified. Additionally, appropriate and effective educational methods to raise awareness of freshwater ecosystem restoration and non-indigenous invasive fish are discussed. Social factors are often the primary determinants of whether conservation efforts succeed or fail. Grounded in the theoretical perspectives of social construction, environmental perception, political ecology, and critical environmental adult education, this thesis provides an important contribution to the practice of interdisciplinary research by demonstrating the ways in which social science complements scientific approaches to environmental management. Utilising semi structured interviews with multiple stakeholder groups and an internet survey targeted at coarse anglers this research found that, while a multitude of perceptions of coarse fish exist, there is also willingness on both sides to engage in communication and develop effective practices to aid in managing the freshwater environment. A number of suggestions for improving legislation that addresses invasive freshwater fish, and several ideas regarding education and compliance, also emerged.

Abstract:
Vicente Ferreira Pastinha, mais conhecido como Mestre Pastinha é a mais importante referência da prática que se convencionou chamar capoeira angola, e também um de seus principais pensadores. Nascido em Salvador no final do século XIX, sua vida perpassa momentos cruciais da experiência Afro-Brasileira das classes subalternas de Salvador ao longo do século XX. A partir da década de 1940, Pastinha leva adiante a proposta de preservar um estilo de capoeira, mobilizando um elemento cultural que ainda carregava negativos marcadores sociais de raça, cor e classe. Ao fazê-lo, procura inscrever também uma biografia que silencia aspectos de seu passado em favor de outros, consolidando-se como um importante intelectual da cidade gingada noção que será desenvolvida em oposição à ideia de cidade letrada. As distâncias, aproximações, travessias e tensões entre esses dois universos são os eixos da presente análise, que destaca o ambiente formador da experiência de Mestre Pastinha no período pós-abolição e seus percursos até 1971. Durante este período, o mestre sai de uma relativa invisibilidade entre os praticantes de capoeira para consolidar o Centro Esportivo de Capoeira Angola (Ceca) no Pelourinho, alcançando um amplo reconhecimento que o leva a percorrer vários estados do Brasil e a visitar a África participando do Primeiro Festival Mundial de Artes Negras no Senegal. Nesse sentido, nosso objetivo é analisar, por meio da trajetória de Vicente Ferreira Pastinha, quais são as condições de emergência, experimentação, consolidação e reconhecimento de saberes subalternos e racializados na Bahia do século XX. Ao mesmo tempo, procura-se apreender os processos de formação e modificação da subjetividade de Pastinha nos entre lugares de dois polos dinâmicos de saberes: a ginga e a letra. Subjaz a esta investigação, o suposto de que Mestre Pastinha contribuiu para a construção de uma versão da democracia racial na Bahia e no Brasil, mas, paradoxalmente, para evidenciar alguns dos controversos limites dessa imaginação nacional.
Vicente Ferreira Pastinha, better known as Mestre Pastinha, is the main reference to the practice of capoeira angola (the Afro-Brazilian martial art) and also, one of its great thinkers. Born in the end of the XIX century in Salvador, Bahia, Pastinhas life evolved in parallel with crucial moments in the historiography of Afro-Brazilian subaltern classes along the XX century. From the 1940s onwards, Pastinha carries forward a proposal to preserve a traditional style of capoeira, a practice still negatively correlated with the social markers of race, colour and class. In doing that, Pastinha looks to create a biography that silences certain dimensions of his past while it privileges others. In the same process, he also affirms himself as an important intellectual of the gingada city (cidade gingada) a notion we define as opposed to the concept of the lettered city. The distances, approaches, crossings and tensions between those two dimensions are the main focus of this analysis, which underlines the role of the environment in Pastinhas experience during the pos abolition period and his pathway until 1971. Along this time, the Mestre emerges from a situation of invisibility among capoeira practitioners, to lead the initiative for the Centro Esportivo de Capoeira Angola (Capoeira Angolas Sport Center) at Pelourinho (Salvadors Historic Center). The wide recognition of Pastinhas experience at Ceca allows him to travel across many Brazilian cities to exhibit the practice of capoeira and to become one of the Brazilian representatives at the First World Festival of Black Arts in Senegal in 1966. Thus, our main goal is to analyse, through Vicente Ferreira Pastinhas trajectory, the conditions of emergence, experimentation, consolidation and recognition of subaltern and racialized knowledges in the XX century Bahia. Additionally, the research aims to comprehend the formation and modification of Pastinhas subjectivity while being in-between two very dynamic poles of knowledge: the letter and the ginga, or the writing and the capoeira. One of the assumptions underlying this research is that Mestre Pastinha contributed to the design of one form of the racial democracy in Bahia and Brazil. However, paradoxically, its trajectory also made visible some controversial limits of that national imagination.

Nous présentons une définition des omega-catégories faibles formulée en théorie des types proposée initialement par Finster et Mimram, suivant des idées provenant à la fois de la théorie homotopique des types et d’une définition des omega-catégories faibles due à Grothendieck et Maltsiniotis. Les avantages d’une telle approche sont multiples : Le langage de la théorie des types permet une définition qui se réduit à quelques règles seulement, et il fournit une syntaxe explicite sur laquelle il est possible de raisonner par induction. Cela donne également un algorithme pour implémenter un assistant de preuve dédié à l’exploration des omega-catégories faibles. Le travail que nous présentons est organisé selon deux axes principaux : Nous étudions les fondements théoriques de cette définition et la relions aux autres définitions connues de omega-catégories faibles, et nous présentons l’assistant de preuve basé sur cette théorie avec des considérations pour rendre cet outil plus utilisable en pratique. Nous considérons également des généralisations de cette approche à d’autres structures supérieures similaires.Nous commençons par présenter une introduction à la théorie des types dépendants sur laquelle repose les définitions que nous étudions, en introduisant à la fois une syntaxe et sa sémantique catégorique. Nous présentons ensuite les omega-catégories faibles avec une théorie des types pour les définir. Nous détaillons la sémantique catégorique de cette théorie et notre contribution principale dans cette direction établit une équivalence entre les modèles de cette théorie et la définition antérieure des omega-catégories faibles due à Grothendieck et Maltsiniotis. Cette définition nous a permis d’implémenter un assistant de preuves capable de vérifier si un morphisme donné est correctement défini dans la théorie des omega-catégories faibles; nous présentons cette implémentation accompagnée de quelques exemples illustrant à la fois les possibilités de l’outil, et l’impraticabilité de son utilisation dans sa version native. Pour corriger ce problème, nous présentons deux fonctionnalités additionnelles permettant une automatisation partielle : La suspension et la fonctorialisation. Ces deux opérations sont définies par des techniques similaires, par induction sur la syntaxe de la théorie des types. Nous généralisons ensuite cette définition des omega-catégories faibles et présentons un cadre pour étudier des théories des types, qui est à la fois suffisamment modulaire pour permettre de définir d’autres structures supérieures, et suffisamment contraint pour étudier précisément sa sémantique. Cela nous permet d’esquisser une connexion avec la théorie des monades à arités. En se reposant sur ce cadre, nous introduisons et étudions deux autres définitions de structures supérieures : les omega-catégories faibles monoidales et les omega-catégories faibles cubiques. Par un raisonnement syntaxique, nous définissons des traductions dans les deux sens entre les théories des types qui définissent les omega-catégories faibles et les omega-catégories faibles monoidales. L’un de nos résultats principaux est de montrer que ces traductions induisent une équivalence au niveau des modèles, montrant que les omega-catégories faibles monoidales sont équivalentes aux omega-catégories qui ont un unique objet justifiant l’appellation de monoidal. Nous donnons ensuite une présentation alternative de la théorie des types pour définir les omega-catégories faibles monoidales, qui diverge de notre cadre, mais qui est plus indépendante, et la prouvons équivalente à la présentation précédente. Finalement nous introduisons dans notre cadre une définition de la théorie des omega-catégories faibles cubiques, et étudions sa sémantique. Notre résultat principal dans cette direction est la caractérisation des modèles de cette théorie des types, en extrayant une définition mathématique qui leur est équivalente
We study a type theoretic definition of weak omega-categories originally introduced by Finster and Mimram, inspired both from ideas coming from homotopy type theory and from a definition of weak omega-category due to Grothendieck and Maltsiniotis. The advantages of such an approach are multiple: The language of type theory allows for a definition restricted to only a few rules, it also provides an explicit syntax on which one can perform inductive reasoning, and gives an algorithm for implementing a proof-assistant dedicated to exploring weak omega-categories. The work we present about this type theory is organized along two main axes: We investigate the theoretical grounds for this definition and relate it to an other known definition of weak omega-categories, and we present the proof-assistant based on this theory together with practical considerations to improve its use. We also consider a generalization of this approach to other related higher structures.We start with an introduction to the language of dependent type theory that we rely on to introduce our definitions, presenting both the syntax and the semantics that we study by means of categorical tools. We then present weak omega-categories and a type theory that defines them. We detail the categorical semantics of this theory and our main contribution in this direction establishes an equivalence between its models and the prior definition of weak omega-categories due to Grothendieck and Maltsiniotis. This definition has enabled us to implement a proof-assistant capable of checking whether a given morphism is well-defined in the theory of weak omega-category, and we present this implementation together with a few examples demonstrating both the capabilities of such a tool, and its tediousness in the vanilla version. To improve this issue, we present two main additional features allowing to partially automating its use: The suspension and the functorialization. These two operations are defined by similar techniques of induction on the syntax of the type theory. We then generalize this definition of weak omega-categories and present a type theoretic framework that is both modular enough to allow for defining higher structures, and constrained enough to precisely understand its semantics. This enables us to sketch a connection with the theory of monads with arities. Using this framework, we introduce and study two other definitions of higher structures: Monoidal weak omega-categories and cubical weak omega-categories. By using syntactic reasoning we are able to defines translations back and forth between the type theory defining weak omega-categories and the one describing monoidal weak omega-categories. One of our main result is to show that these translations imply an equivalence at the level of models: It shows that the monoidal omega-categories are equivalent to the omega-categories with a single object thus justifying the correctness of the appellation monoidal. We then give an alternate presentation of the type theory defining monoidal weak omega-categories, which diverges from our framework but is more standalone, and prove it to be equivalent to the previous presentation. We finally introduce in our framework a definition of cubical weak omega-categories and study its semantics, our main result along these lines is to characterize the models of this type theory and extract a mathematical definition equivalent to them

Cataloged from the official version of thesis.
Includes bibliographical references (pages 77-79).
Studies have shown that participating in creative hobbies is important for our physical and mental health. It has also been proven to boost our productivity and creativity at work. Yet, despite these benefits, we still have not seen the rise of a cultural movement similar to the exercising craze that has taken hold in the last two decades. Why are we not intentionally setting aside time to spend on our hobbies in the name of wellbeing and longevity? The answer is that creative hobbies are not "cool," and that is mainly because young urban professionals, the trendsetters of their communities, have not fully bought into them yet. The purpose of this thesis is to carve out a new space for a creative hobbies movement based on Mihaly Csikszentmihalyi's concept of flow. Through both a human centered design and systems architecture approach, we look at the time allocation behavior of our target audience and determine how to best market this new space to them. We propose a set of design recommendations that are aimed at elevating creative hobbies and eventually bringing them into the cultural mainstream. Finally, we imagine the positive impact this could have on our society. Firstly, by offering more meaningful alternatives to today's most popular pastimes (watching TV and surfing the web) and secondly, by offering more equitable avenues to finding purpose.

Abstract:
L'objectif du projet de recherche PASTIS est la construction d'une machine de vision dans le domaine du dessin au trait. Dans ce cadre, nous avons etudié un traitement de niveau intermédiaire dans la hiérarchie visuelle : la vectorisation d'image, c'est-à-dire l'extraction à partir d'une image de sa description sous forme de droites. En regard aux techniques coûteuses et sensibles au bruit, telles que l'approximation polygonale, diverses méthodes existent qui proposent soit une évaluation rapide de l'existence ou non de droites dans l'image : transformée de Hough, ou simplement le renforcement de caractéristiques locales par des méthodes de filtrage: template matching ou érosion et dilatation morphologiques. A la suite de celles-ci, nous proposons une démarche cellulaire d'extraction de segments orientés. Ces segments sont ensuite regroupés pour former des droites orientées, à la manière de la transformée de Hough. Cette méthode n'est pas très sensible aux petits bruits, par exemple la perte de connexité de pixels. Elle permet un fonctionnement de type essai-erreur, en modulant par divers paramètres sa propre acuité. L'exploration de cet algorithme ne se conçoit pas sans une recherche appliquée pour obtenir une architecture réalisant celui-ci en temps raisonnable: le linéaire est une obligation, si l'on tente, comme l'oeil, de traiter cent millions de points élémentaires en une dizaine de millisecondes. Pour cela, nous avons spécifié, conçu et réalisé deux circuits ASIC (application-specific integrated circuit), en technologie CMOS 1,5 m. Ceux-ci forment la base d'un processeur rapide de rotation, qui aux dépens de la précision dépassé de loin les réalisations similaires existantes

Capes
A cultura musical da capoeira apresenta processos que envolvem narrativas e personagens, que, através da transmissão oral, permitem que uma tradição perpasse décadas e permaneça através das gerações, usando procedimentos como observação, imitação, repetição, correção e erro, que caracterizam tais ambientes de educação. Esta tese é fruto de uma pesquisa em Educação Musical vinculada ao Programa de PósGraduação da Escola de Música da Universidade Federal da Bahia, PPGMUS UFBA, e tem como personagem principal Mestre João Pequeno de Pastinha. Mais especificamente está ligada à subárea educação musical em ambientes sócioculturais de transmissão e tradição oral de ensino, é um estudo de caso qualitativo e descritivo de práticas musicais de capoeira angola na Academia de João Pequeno de Pastinha, localizada no Centro Histórico de Salvador, BA. O objetivo foi identificar, sistematizar e analisar os processos de ensinar e aprender música neste ambiente. Os dados, colhidos entre 2013 e 2016, foram extraídos de publicações acadêmicas sobre capoeira e educação; pesquisa de campo, com entrevistas direcionadas a um ex-aluno do Centro Esportivo de Capoeira Angola, CECA, fundado por Mestre Pastinha, e a mestres, contramestres, discípulos e familiares de Mestre João Pequeno. Mesmo depois do seu falecimento em 2011, este continua uma das principais referências da capoeira angola, com filiações de seu trabalho em todo o Brasil, países da Europa e América do Norte. O texto traz primeiramente uma abordagem crítico/histórica sobre as representações sociais desta prática popular afro-brasileira originalmente marginal, mas que se tornou patrimônio da humanidade e instrumento pedagógico, com possibilidades de utilização em disciplinas escolares, entre elas, a educação musical. Em seguida, o trabalho apresenta uma descrição dos procedimentos de ensino e aprendizagem de música utilizados nesta capoeira. A análise sugere que os valores de cooperação, respeito e autonomia, presentes nesta prática musical, contrapõem-se a valores de padronização e às relações de dominação tão impregnadas na escola tradicional.

Baseball has often been seen as America’s Pastime, etched into the cultural landscape of the United States for over 100 years. However, recent shifts both in cultural landscape and the sport industry puts this moniker into question. Whether Americans consider baseball the national pastime is currently up for debate. The crux of that debate for individuals may be influenced by their emotional attachment to the sport or an emotional attachment to competing sports.

Weir, Gillian. "Spelling, punctuation and material culture in the later Paston letters." Thesis, University of Glasgow, 2018. http://theses.gla.ac.uk/30912/.

Full text
Abstract:
This thesis examines the spelling practices and letter-writing conventions to be found in the letters and papers of the Paston family and their circle during the sixteenth and seventeenth centuries. Hitherto, most scholarly attention has been on the fifteenth-century material found in Paston archives, with comparatively little research undertaken on the extensive later materials. This thesis is intended as a partial attempt to address this lacuna, drawing on new approaches to the study of early modern English letters. It draws upon a new comprehensive diplomatic transcription of the materials, consisting of approximately 500 documents containing 200,000 words. Building on an earlier pilot study (Weir 2009), the thesis falls into three main chapters, each addressing the collection from a distinct perspective, framed by a contextualising introduction (chapter 1) and a conclusion summarising the findings of the thesis and offering suggestions for future work (chapter 5). Chapter 2 begins with a key question: (1) How did letter-writing conventions of address and subscription alter and develop - if at all - through the Early Modern period, and are these changes reflected in the Paston family correspondence? The thesis demonstrates how the letters preserved in London, British Library, Additional MSS 27447, 27448 and 36988 displayed adherence to formulaic usages, even though, across the 150 years of their construction, there is a notable shift towards shorter constructions. Further research questions linked to these issues involved in address and subscription engage with the material culture of the correspondence: (2) What materials are used for the letters in question? (3) How do writers relate text to space? (4) How were the letters delivered to their recipients, and how and for what reasons were they preserved? Across the collection of letters, there was a clear development in the material culture of letter-writing, most notably through the development of the postal networks in the period, even though letter-writing tools remained relatively unchanged for centuries. Chapter 3 examines spelling practices in the letters. It addresses the following research questions: (1) How standardised were the Paston letters? (2) To what extent do spelling practices differ between male and female letter- writers? (3) Where such practices vary within an individual’s lifetime is it possible to identify the social factors which contributed to that change? (4) To what extent – and if so why -- do these habits vary between generations of the same family? In order to answer these questions, the spelling habits of Robert Paston and his family were examined, along with a number of letters by identifiable female letter-writers. The thesis demonstrates that the letters in the collection displayed a move towards more standardised spellings, but that the use of personal spelling systems and non-standard variants was still very much in evidence. Chapter 4 focuses on further pragmatic features characteristic of Early Modern English correspondence, with a special focus on the function of punctuation. Research questions addressed include: (1) If punctuation is used at all, in what context is it deployed? (2) How – if at all -- does the use of punctuation vary between male and female correspondents? In addition, this chapter will look at communicative acts within the letters including politeness, terms of address, and the use of formulaic constructions, leading to a further question: (3) To what extent do more general pragmatic features vary across the generations and genders of letter-writers? The thesis finds that punctuation practices of female writers vary considerably, even within the output of single individuals, but also that such variation and unconventional usage was not restricted to them. However, during the period covered by the archive there is a clear progression from the use of virgules and limited punctuation through to the deployment of punctuation broadly recognisable to present-day readers.

Abstract:
Pastis est un nouveau système de gestion de fichier pair à pair qui se démarque des systèmes existants par son architecture entièrement décentralisée et sa capacité à supporter un grand nombre d'utilisateurs. Pastis s'appuie sur la table de hachage distribuée Past, qui lui fournit ses propriétés d'auto-organisation, de tolérance aux fautes, de disponibilité et de passage à l'échelle. Pastis propose trois modèles de cohérence, permettant aux applications de choisir le compromis adéquat entre performance et cohérence des accès au système de fichiers. Ces modèles tirent parti des propriétés de localité de Past pour optimiser les accès réseau et augmenter les performances du système. Pastis garantit l'intégrité des données en s'appuyant sur des techniques cryptographiques et en implémentant un contrôle d'accès utilisant des ACL partagées. L'évaluation de Pastis en environnement émulé et simulé suggère que ses performances sont comparables ou supérieures à celles des systèmes existants.

Full text
Abstract:
In the form of a potable spirit, an extract of grapefruit skin has been found to develop an attractive opalescence when diluted to below about 38 % ethanol (v/v). This phenomenon is analogous to the pastis effect, called louching, common in many drinks popular in some countries bordering the Mediterranean. The main objective of this research was to develop spirit liquor with commercial potential from grapefruit skin, largely a waste commercial product, as the dominant if not exclusive ingredient other than alcohol and water. This would require making extracts by distillation of undried skins, which would develop a dense opalescence significantly below 40 % v/v ethanol, the common alcoholic strength of spirits as sold in New Zealand. The product concept was thus a clear liquid which when poured over ice for example, would yield a cool opalescent drink with a characteristic grapefruit flavour. In the case of citrus, the chemical basis of louching is the greater solubility of citrus skin terpenes, principally limonene, in ethanol than in water. The louch point is synonymous with the chemical expression critical micelle concentration, detected here by light scattering at the arbitrary wavelength of 450 nm. Early results with an obvious opalescence showed that the alcohol concentration at which the terpenes ceased to be soluble in the grapefruit distillate was about 38 % (v/v). This point was similar to that for pastis (Pernod brand), where the principle louchable ingredient is anethole. However, the light scattering was much greater for pastis. Thus, a grapefruit spirit sold at 40 % ethanol with the louching intensity of pastis should require increasing the solubility of limonene in solutions with a lower ethanol concentration. This in turn should allow higher concentrations of limonene in true solution in 40 % ethanol, theoretically resulting in a more intense louch in the final drink. Thus, a broad range of hydrocolloids and surfactants was tested in an attempt to increase the solubility of limonene in lower ethanol concentrations. None of hydrocolloids or surfactants lowered the louch point of a standard limonene concentration in ethanol/water. The informal flavour assessment showed that the spirit flavour from grapefruit zest alone lacked intensity. It was then thought that better flavour might be obtained by using the whole grapefruit (zest, pith, and juice) rather than zest alone. The additional of pith or pith plus juice caused no significant change in the louch point or light scattering. However, the final flavour was informally judged to be more intense than that derived from zest alone. The problem still remained that the light scattering of grapefruit distillate was never as high as that achieved by pastis, even though it was found (by gas chromatography) that the concentration of limonene (w/w) in the grapefruit spirit was at least as high as that of anethole in pastis. The cause was due to the fact that as a louched compound, anethole was a solid with a flat crystal structure because the melting point (21.4C) is well above that of a cool drink (Handbook of Chemistry and Physics, 1947). By contrast, limonene remains a liquid even in an iced drink because its melting point is far below 0C. Flat crystals would obviously scatter light far more than would a micelle containing a liquid, in this case limonene. Although such a grapefruit distillate did not louch as well as pastis, it could still have market potential on the basis that it would be made from the distinctive New Zealand cultivar of grapefruit. Thus a formal sensory assessment was conducted, using a focus group. The grapefruit distillates at 40 % ethanol were perceived by most panellists as refreshing, clean, fruity, and citrusy in aroma, but somewhat deficient in grapefruit flavour, and there was a common perception of strong chemical finish. At this stage of development a commercial proposition cannot be sensibly made.

Abstract:
The study examines the character of Margaret Paston through a selective reading of Paston Letters and Papers of the fifteenth century. Consideration is given to the problems posed by the letter form, to the identification of an authentic "voice" in the letters of a woman who was probably unable to write, and to the constraints of an incomplete historical record. Margaret is viewed by means of her own words and her relationships with her immediate and extended family, and in the light of the social and political circumstances of the time. It is concluded that by examining Margaret in this way, there is sufficient material in the epistolary record to make an assessment of her character.

Abstract:
Magíster en gestión cultural
El presente trabajo tiene como objetivo investigar acerca del patrimonio cultural existente en Capitán Pastene, un pueblo ubicado en la región de la Araucanía, donde se asentó un grupo de ochenta y ocho familias italianas, llegadas a Chile durante los años 1904 y 1905, buscando mejores oportunidades de vida y de desarrollo en el ámbito de la agricultura. Desde entonces, ya existen cinco generaciones de pasteninos que han desarrollado su vida, tradiciones y cultura en este lugar. Sin embargo, cabe preguntarse si, con el paso del tiempo y la asimilación cultural, aún persisten vestigios patrimoniales del proceso de asentamiento que dio origen a este pueblo. La pregunta de investigación se aborda a través de la reconstrucción bibliográfica del proceso histórico realizado por los inmigrantes, junto con una serie de entrevistas en profundidad y observaciones en terreno acerca de la existencia del patrimonio tangible e intangible que dé cuenta de dicho proceso. Esta investigación adquiere especial significado en el rescate identitario de los habitantes de Capitán Pastene, especialmente en el de los descendientes de los italianos fundadores, pero también representa la posibilidad de rescatar una parte de la pluralidad cultural que conforma al pueblo de Chile.

Full text
Abstract:
This thesis questions the prevailing historical models of the medieval family, using the Paston family as a test case. It reviews the theories of three prominent historians of the medieval family: Lawrence Stone, Ralph Houlbrooke and Joel Rosenthal. Whether the Paston family and particularly the women fit the models of families as defined by the above mentioned historians is the underlying question. If the Paston family does not fit these models, what does that tell us about the current assumptions made concerning the fifteen th century family? The thesis illustrates that the family models of Stone do not always apply to the Pastons. Houlbrooke's and Rosenthal's ideas on family are much more reflective of the lives actually led by the Pastons. Therefore, while we can not say that the Pastons were average, they were certainly not exceptional. The lives of the women did not fit the models as established by Stone. Their power came from the home itself, as they managed the estates, educated their children, protected their property and looked after the future financial interests of the family. Houlbrooke allows for this form of power in his studies on women. Rosenthal tends to skirt the issues of women focusing more on the power that they received as widows not as wives. If the theories of our three historians were correct or encompassing enough they would have enfolded the Paston family. Houlbrooke's theories did this. Rosenthal's arguments did not include all aspects of the family, particularly children and education. Stone's arguments, with few exceptions, did not fit the Pastons at all. If we allow for a diversity of family structures and a diversity of roles and relationships within that structure, then we will have a much more accurate picture of the fifteenth century family.

Dissertação de Mestrado Integrado em Medicina Veterinária
Anthelmintic resistance in horses has increased in recent years and the continuous search for alternative control methods has led to the development of complementary approaches such as biological control. This approach can make use of parasiticide fungi, such as Duddingtonia flagrans and Mucor circinelloides, in parasite population control and recent research has been focused on the development of new administration methods. Following this line of research, a new and alternative formula has been developed by using a lyophilized product that contained both D. flagrans and M. circinelloides spores for the control of gastrointestinal nematodes in horses. After the product manufacture and the normal spore morphology were assessed, these were tested for in vitro growth. A total of 20 Petri dishes were assembled with a mix of 0.1 g of product and 0.5 ml of water in solid media. The assembled plaques were kept at 25ºC in total darkness and all showed the development of new fungi spores after 10 days. Following the in vitro assessment, the product was administered per os to horses in order to observe their effect in the faecal egg count (FEC) of eggs per gram (EPG). Thus, one group of 5 horses in a pasture was chosen to receive 10 g of product (with M. circinelloides spores and a total of around 105 D. flagrans chlamydospores per horse), 3 days a week starting in September, and another group of 7 horses in an adjacent pasture remained as control. Following treatment with Ivermectin pour-on in September 2017, a faecal sample was collected from each horse on a monthly basis and FEC was assessed using a Modified McMaster technique. Only gastrointestinal nematode eggs, namely strongyle eggs, were observed with this technique. The EPG average from each group was compared for each individual month and overall to see the reduction effect achieved with the fungi treatment. Statistically significant differences were found between the two groups in February (72% reduction), March (64% reduction), and overall, 66% reduction. The horses in the test group only reached a cut-off value of 300 EPG two months after the horses in the control group. In November and January, faecal culture method was applied to all faecal samples, showing only the presence of cyathostomin larvae. This study allowed the successful development of a new formula for the administration of parasiticide fungi to horses, based on lyophilized product, which increases the possibilities for future product development and application. New and improved ways of biological control should be developed and implemented to increase parasite control and reduce anthelmintic resistance cases.
RESUMO - NOVA FÓRMULA DE ADMINISTRAÇÃO DE FUNGOS PARASITICIDAS PARA PREVENIR INFEÇÃO POR NEMÁTODES GASTROINTESTINAIS EM CAVALOS DE PASTOREIO (LUGO, ESPANHA) - A resistência a anti-helmínticos em cavalos tem vindo a aumentar recentemente e a procura por métodos de controlo alternativos levou ao desenvolvimento de abordagens complementares como o controlo biológico. Esta abordagem usa fungos parasiticidas, como Duddingtonia flagrans e Mucor circinelloides, no controlo da população parasitária e estudos recentes têm-se focado no desenvolvimento de novos métodos de administração. Seguindo esta tendência, uma fórmula nova e alternativa foi desenvolvida utilizando um produto liofilizado que contém esporos de D. flagrans e M. circinelloides para o controlo de nematodes gastrointestinais em cavalos. Após fabrico do produto e verificação da morfologia normal dos esporos, estes foram testados para crescimento in vitro. Um total de 20 placas de Petri foram semeadas com uma mistura de 0.1 g de produto e 0.5 ml de água em meio sólido. As placas foram mantidas a 25ºC em escuridão total e todas demonstraram desenvolvimento de novos esporos passados 10 dias. Após a verificação in vitro, o produto foi administrado per os a cavalos para observar o seu efeito nas contagens fecais de ovos (CFO) por grama (OPG). Assim, um grupo de 5 cavalos em pastoreio foi escolhido para receber 10 g de produto cada (com esporos de M. circinelloides e um total de cerca 105 clamidosporos de D. flagrans por cavalo) 3 vezes por semana, de setembro a março. Outro grupo de 7 cavalos numa pastagem adjacente foi utilizado como controlo. Após tratamento com unção contínua de Ivermectina em setembro de 2017, uma amostra fecal de cada cavalo foi colhida mensalmente e o CFO foi avaliado utilizando a técnica de McMaster modificado. Apenas ovos de nemátodes gastrointestinais, nomeadamente estrongilídeos, foram observados com esta técnica. A média de OPG de cada grupo foi comparada para cada mês e no total do estudo para observar o efeito de redução do tratamento fúngico. Diferenças estatisticamente significativas entre os dois grupos foram observadas em fevereiro, redução de 72%, março, redução de 64%, e no total, 66% de redução. Cavalos no grupo de teste só passaram o limiar de 300 OPG dois meses depois dos cavalos do grupo controlo. Em novembro e janeiro foram realizadas culturas fecais em todas as amostras, demonstrando apenas a existência de larvas de ciatostomíneos. Este estudo permitiu com sucesso o desenvolvimento de uma nova fórmula para administração oral de fungos parasiticidas para cavalos com base num produto liofilizado, aumentando as futuras possibilidades de desenvolvimento e aplicações de produtos. Novas e aperfeiçoadas formas de controlo biológico devem ser desenvolvidas e implementadas para aumentar o controlo de parasitas e diminuir os casos de resistência a anti-helmínticos.

Abstract:
This investigation into the origin of a collection of nineteenth century lanternslides revealed evidence of the social, intellectual and cultural importance of various scientific societies in Oxford, and the contributions made by those involved, particularly the creator of the lanternslides, H. M. J. Underhill, (1855–1920). Evidence gathered from primary sources showed a fluidity of relationships between the supposed ‘town and gown’ in late nineteenth century Oxford which consisted of a community of citizens, amateurs and academics, all of whom were linked by a growing interest in the real and mythological British past. Following a discussion of the key intellectual and social influences in Britain during the latter half of the nineteenth century, including the implications of the emerging evidence of an ancient human past, the thesis focuses on individual case studies. They illustrate the roles of overlooked or neglected individuals whose work contributed to the growth of today’s discipline of British prehistory. Several people, now forgotten, including Underhill were contemporaries of Arthur Evans and Edward Tylor whose social circumstances made it easier for them to become prominent academics. The results of this research indicate that a new approach is required in the history of archaeology; one that would draw attention to the vital contributions made by forgotten or overlooked individuals, societies and popular publications. Further attention to these issues will shed new light on the way that prehistoric archaeology moved from an antiquarian pastime to an academic discipline between 1850 and 1900.

Abstract:
Called “The Pride of the Bluegrass,” Elmendorf Farm changed the style and substance of commercial pedigree breeding in early twentieth-century America. Between 1897 and 1914, James B. Haggin readily transformed the Kentucky farm first as a nationally preeminent horse stud, famous for its bloodlines and scales, and second as a premier dairy operation, exceptional for its sanitation, science, and size. Here rested the large-scale production of the world’s fanciest Thoroughbreds and finest milk. At the same time, Haggin’s farm reflected a lifestyle that has come to be celebrated and cherished as the ideal Kentucky landscape. A factory-style plant of large scales, of specialization, and vertical integration was disguised with the lavish iconography of portico mansions, rolling lawns, and white-planed fences, behind which million-dollar animals grazed on lush bluegrass. But a crucial, and significant, characteristic of this farm was the wage laborers who performed the back-breaking work. The labor and lives of the farm’s black workers, in particular, shows how Elmendorf helped reinforce a system of labor relations in central Kentucky, one peculiar to horse business and one segmented by race. Ultimately, this study of Elmendorf Farm shows the unforgettable imprint of Haggin’s complex personality, as well as his modern philosophies of business, but it also demonstrates conclusively the fallacy of an acquisitive nature and aggressive impulses in commercial animal breeding. As a powerful financier in the late nineteenth-century, Haggin’s perpetual objective was ever “large economies of scale.” Haggin made and lost fortunes by creating great industrial enterprises, and his Bluegrass stud proved no different—even if his individual actions meant defying the norm and jeopardizing entire industries. This best explains why the world’s greatest breeding and milking farm, in many ways, failed. When Haggin applied a dual logic of industrial and aristocratic expansion to a Kentucky breeding farm, the pedigree industry, however fragile and vulnerable, was pushed to extremes and instability of both horse and milk industries resulted. Those famed marble columns, the remaining evidence of Elmendorf Farm, now stands in a lush Bluegrass field, representing one of the most spectacular failures in modern agricultural history.
