Abstract:

Este trabalho estuda o processo de trefilação combinada do aço SAE 1045, que consiste nas etapas de pré-endireitamento com múltiplos rolos, jateamento, trefilação, corte e endireitamento por rolos, tendo como produto final barras acabadas trefiladas. Este produto final é empregado na fabricação de hastes de amortecedores para indústria automotiva. O Objetivo do estudo é de entender como são geradas e como se comportam as principais heterogeneidades mecânicas do material processado e a influência dos parâmetros do processo e das características do material na formação e modificação dessas heterogeneidades, buscando como resultado parâmetros otimizados para o processo. Foram variados no processo três parâmetros e avaliadas a interação existente entre eles. Os parâmetros modificados foram ângulo da ferramenta de trefilação (fieira), o ângulo de endireitamento e polimento por rolos cruzados (PERC) e a colocação de revestimento de carbo-nitreto de titânio (TiCN) no núcleo da ferramenta de trefilação (fieira). Foi realizada caracterização do aço, como microestrutura, composição química e microdureza. As tensões residuais superficiais das amostras foram caracterizadas utilizando o método de difração de raios-X. Após avaliação das tensões residuais superficiais, foi analisada a variação das tensões com a profundidade através do método do furo cego (hole-drilling), A classificação das inclusões foi de acordo com o método microscópico A (“piores campos”) da norma ASTM E45-97, feita através da maior severidade encontrada analisando o material aleatoriamente através de varredura com microscópio em sua superfície. Os resultados obtidos permitiram conhecer a combinação de ângulo de fieira e de endireitamento por rolos cruzados (PERC) mais favoráveis para gerar níveis baixos de tensões residuais. Além do ângulo, foi possível verificar que a geometria das zonas da ferramenta de trefilação (fieira) influência os níveis de tensões residuais após a trefilação. O núcleo da fieira com revestimento em todos os ensaios realizados apresentou menores níveis de tensões residuais, mostrando ser uma condição importante para a otimização do processo principalmente para a redução das tensões trativas após a trefilação.
This paper studies the process of cold drawing combined SAE 1045 steel, which consists of the steps with multiple pre-straightening rolls, sandblasting, drawing, cutting and straightening by rollers, with the final product finished extruded bars. This final product is used in the manufacture of rods of shock absorbers for the automotive industry. The objective of the study is to understand how they are generated and how they behave the main mechanical heterogeneities of the processed material and the influence of process parameters and material characteristics of the formation and modification of these heterogeneities, seeking as a result the optimized parameters for the process. We varied three parameters in the process and evaluated the interaction between them. The parameters were modified angle of wire drawing tool (spinneret), the angle of straightening and polishing rolls (PERC) and the placement of coating titanium carbo-nitride (TiCN) in the core of the wire drawing tool (spinneret). We performed characterization of steel, such as microstructure, chemical composition and microhardness. The surface residual stresses of the samples were characterized using the method of X-ray diffraction. After evaluation of surface residual stresses, we analyzed the variation of stress with depth by the method of blind hole (hole-drilling), Classification of inclusions was according to the microscopic method ("worst fields") of ASTM E45 -97, made more severe by analyzing the material found randomly through scanning with microscope on its surface. The results obtained allow us to know the combination of angle stringer and straightening by rollers (PERC) more favorable to generate low levels of residual stresses. In addition to the angle, we found that the geometry of the areas of wire drawing tool (spinneret) influence the levels of residual stress after wire drawing. The core of the spinneret clad in all tests had lower levels of residual stress, proving to be an important condition for the optimization of the process mainly to the reduction of tensile stress after wire drawing.

Abstract:

År 1054 skedde en splittring mellan kristendomens två största inriktningar, den ortodoxa och den katolska kyrkan. Detta skedde efter århundraden av oenigheter, missförstånd, maktkamper med mera. Förutom maktkamperna berör konflikterna Kristi natur och Filioque tillägget. Uppsatsen berör även relationerna mellan den ortodoxa och den katolska kyrkan efter splittringen. Undersökningen visar att det finns skillnader i hur olika författare återger de historiska händelserna. Detta förstärker bilden av två kyrkor som inte är eniga om vems fel splittringen var och vilka händelser som var mest avgörande.

Abstract:

Psalm 104 paints a picture of Yahweh dressed in the royal robes of both Aten and Baal. The variety of references to Ancient Near Eastern gods points to a rich and complicated history of the origins of Psalm 104, Israel and Israelite theology. The origins of Psalm 104 in all likelyhood include oral traditions, cultic contexts and years of redactional rearrangement and rewriting. Akhenaten used a centralised cult and monolatrism to achieve political stability in Egypt. Years later Hammurabi used Marduk as chief deity in Babylonia to centralise power and create political and religious stability in his kingdom. It is within this Ancient Near Eastern tradition of using religion and one specific deity to achieve political stability that Psalm 104 finds its origins and cultic context. The early Israelite monarchy finds itself amidst uncertain political circumstances. The early kings used a centralised monarchy and monolatrism to achieve economic and political stability. The early Israelite government also used other Egyptian influences including governing methods, policies and the use of Egyptian scribes. The monarchy used cultic personal to communicate politically sanctioned theology and contact between cultic personal and Egyptian scribes intertwined with a Canaanite heritage has a cosmopolitan and culturally diverse Psalm 104 at its end. The psalm is used as a war liturgy, with Chaoskampf-motifs to legitimise the Israelite king s military action and kingship. This is done by ritual re-enactment on cultic level connecting Yahweh s mythic action to that of the king s present conflict.

Abstract:

This thesis attempts to examine and define the degree of influence which the Turks exerted on Islamic art of the Seljuqid period (1040--1194 AD) specifically, and on Islamic art of the medieval period generally. As this thesis represents a first investigation of the topic, it was necessary to retrace Turkish history from its beginnings to fully understand its dynamic, but also to analyze the art historical and cultural past of the Turkish peoples in order to assess the degree of probability of Turkish influence on Islamic art as well as the means of its penetration. The vaster arena of this research is the field of Central Asian history and the growing awareness of the important cultural ramifications of its widespread Indo-Buddhist culture.
Due to the complexity of the thesis topic, a simple method has been followed to present the material. The thesis is divided into three chapters, each addressing a major issue. The first chapter introduces the four major Turkish steppe dynasties and their art in so far as archaeology permits. The second chapter deals with the process of Islamicization of the Turks, while the third chapter broaches the issue of Turkish influence on Islamic art of the Seljuqid period under four headings: architecture, architectural decoration, animal imagery, and figurative iconography. The basic premise of this paper is the assumption that, if the Turks played such a major role in the political developments of medieval dar al-islam, they must have also contributed, consciously or not, to the formation of medieval Islamic art.

Thesis (MDiv (Practical Theology and Missiology))--University of Stellenbosch, 2007.
ENGLISH ABSTRACT: According to the researcher, there is a crisis in the faith formation of the adolescent within the family. He is of the opinion that the crisis is a faith identity crisis that is the result of the sucking effect of a secular democracy that manifest in a materialistic orientation of Christian parents. That in turn, influences the faith formation of and the “passing of the faith” to the adolescent negatively, through the fact that they also get caught up in this materialistic culture. The aim of the research is therefore to determine the extent and depth of the crisis of the Christian family’s spirituality in post apartheid South Africa. The researcher thereby wishes to present certain principles for a new partnership between the church and the family. The researcher firstly studies the true nature and composition of the family by gaining a theological perspective on it. He also tries to show that covenant education is also faith formation. To prove this assumption that nuclear families are in an identity crisis, a study is undertaken about the nature of culture and how a change in culture also changes the present worldview of Christians. These changes also give rise to a youth culture that is maintained by the mass media, which influences adolescents’ faith formation further. The empirical research aims to validate the literature study, by investigating the material contexts and orientation of adolescents and parents, as well as their spiritual growth. From the empirical study the inferences are made that parents doesn’t take full responsibility for the faith formation of adolescents. In stead, parents model their vulnerability against a materialistic secular culture that works negatively in on adolescents’ faith formation. To address this problem, a holistic, comprehensive partnership between the church and the family is necessary. This will also contribute to the fact that the church will be healthier and more faithful in her witness to the world.

Abstract:

Submitted to the Faculty of Arts in fulfillment of the requirements for the Degree Mater of Arts in the Department of Criminal Justice at the University of Zululand, South Africa, 1992.
The prisoner, and especially the "board prisoner", is confronted with the possibility of becoming institutionalised. While being incarcerated in the conventional prison, his life world is of necessity institutionally ruled and governed- Upon release he is confronted with a world where he once more has to make his own decisions; he has to be prepared for his reintroduction into a free society and for taking up his responsibilities and obligations as a free citizen. This entails much more than finding accommodation or employment - the question arises whether the conventional prison is the appropriate place for this process of reintegration into community life. The establishment and efficient functioning of transitional havens may be instrumental in preparing the prisoner, who is still under sentence and whose treatment programme makes provision for admittance to such an institution, for reintroduction into free society. The objective of this study was to undertake an investigation of existing research literature relating to transitional havens, in order to describe the origin and development as well as the structure and functioning of these institutions. Arising from the "reintegration model" with its emphasis on community treatment and community integration, the prisoner is assisted and supported towards returning to society as Cx5 a responsible and accountable person- As a community-based release preparatory approach, transitional havens offer a unique opportunity towards addressing the needs of the prisoner. The creation and development as well as the structure and functioning of transitional havens are described. The rapid expansion of transitional havens was originally based on the theoretical assumption that these havens would lower residivism, ensure more humane treatment and reduce expenditure. Apart from different names given to transitional havens by different countries, or even states within countries, it appears that control of these havens may rest with the state or private welfare organisations. Transitional havens controlled by the state are run at lower cost that those controlled by private institutions. State controlled havens utilise the services of personnel, who also serve in conventional prisons, on a rotating basis. It has been found that, with regard to the selection of residents, different criteria is adopted. The intervention programme includes, inter alia, personal counselling, family and marital therapy, reality therapy and social ski1Is training. The transitional haven is regarded as the focus point for the mobilisation of community members and community sources towards addressing the needs of ex-prisoners by facilitating co-operation with existing organi- sations, such as training centres, businesses and service centres. The haven encompasses Cxi> the very important possibility that convicted persons may be transferred there directly, allowing them to continue with professions held prior to conviction. The creation of transitional havens will therefore serve two important objectives: firstly, it wil1 counteract institutional dependency amongst prisoners who qualify for admittance and secondly, it will contribute considerably towards the prisoner's reintegration into community life- > Based on this study it is recommended, as a matter of priority, that the creation of transitional havens by the Department of Correctional Services, be considered-

Full text

Abstract:

In all coating applications, a liquid film displaces air in contact with a dry solid substrate. At a low substrate speed a thin uniform wetting line is formed on the substrates surface, but at a high speed the wetting line becomes segmented and unsteady as air becomes entrained between the substrate and the liquid. These air bubbles affect the quality of the coated product and any means to postpone this at higher speeds without changing the specifications of the coating liquid is desirable. This research assesses the validity of a theoretically based concept developed by Blake and Rushack [1] and exploited by Cohu and Benkreira [2] for dip coating. The concept suggests that angling the wetting line by an angle ß would increase the speed at which air is entrained by a factor 1/cos ß. In practice, if achieved this is a significant increase that would result in more economical operation. This concept was tested in a fast coating operation that of curtain coating which is already enhanced by what is known as hydrodynamic assistance [2]. Here we are effectively checking an additional assistance to wetting. The work, performed on a purposed built curtain coater and a rotating die, with a range of fluids showed the concept to hold but provided the data are processed in a way that separate the effect of curtain impingement from the slanting of the wetting line.

Abstract:

The feasibility of using oriented polymer technology in the design and manufacture of mechanical power transmission belts has been investigated. Working from an initial selection of polymers a die-drawing technique for orienting the polymers was devised, and the static and dynamic mechanical properties of the oriented polymers were investigated. These results indicated that PP, PBT, PPS and PEEK were suitable for further research. Of these 4 materials PBT was selected as the most appropriate material for belt manufacture based on cost, processability (drawing temperature, natural draw ratio) and limitations of laboratory equipment. A technique based on free-tensile drawing combined with simultaneous rotational motion was designed and used to manufacture oriented PBT flat belts from cylindrical injection moulded preforms. The technique used a tensile machine with two pulley-clamps, a fitted heated chamber and an electric motor to provide rotational motion to the belt during drawing. Two types of oriented PBT flat belts with different cross sections were produced successfully, termed 'thick' and 'thin'. These belts were tested on a purpose-built rig comprising two equal diameter pulleys, one driven by an electric motor and the other connected to a generator to provide load. The belt life and power transmission performance was investigated at various conditions of speed, transmitted torque and tension, and the results indicated that despite their smaller cross section 'thin' flat belts demonstrated up to 3 times longer life. However life was only 100hours, which was very low compared with conventional flat belts that last for many thousands of hours at higher speeds and much greater power transmission capacity. Synchronous belts were then produced through the same manufacturing method used for flat belts. This aspect of the research concentrated on the initial pitch design and size, i.e. the timing. Initially a rectangular tooth profile was selected for its simplicity in terms of manufacture. The produced belts exhibited high pitch length variation as well as deformed teeth and were not usable for synchronous power transmission. An extra timing feature was included to control orientation; reducing the pitch length variation enabling consistent tooth production. It was observed that the areas between the extra timing feature and the tooth edges did not orient completely with some regions remaining undrawn. Finite Element Analysis (FEA) was used to predict the drawing behaviour of different shapes and dimensions of the timing features. The results suggested that a 4mm wide and 7mm long slot provided the highest possible extension and the minimum non-oriented regions on the groove. Whilst, the thickness and width of the drawn belt timing features showed differences to the FEA predictions, manufactured synchronous belts based on that design had much better controlled dimensions and the lowest achieved pitch length variation ( ±1%), compared to initial attempts. It is concluded that oriented polymers have the potential to be used in power transmission belts since they offer higher stiffness, tensile strength and creep resistance compared with isotropic polymers that are currently used in commercially available belts such as thermoplastic polyurethane (TPU) and polyvinyl chloride (PVC). The main disadvantages were the lack of dimensional stability and number of cycle to failure.

Thesis, University of Bradford, 2010. http://hdl.handle.net/10454/5223.

Full text

Abstract:

As a preliminary starting point for the present study, physical and mechanical properties of polypropylene nanocomposites (PPNCs) for samples received from Queen's University Belfast have been evaluated. Subsequently, polymer/clay nanocomposite material has been produced at Bradford. Mixing and processing routes have been explored, and mechanical properties for the different compounded samples have been studied. Clay intercalation structure has received particular attention to support the ultimate objective of optimising tensile and fracture behaviour of isotropic and die-drawn PPNCs. Solid-state molecular orientation has been introduced to PPNCs by the die-drawing process. Tensile stress-strain measurements with video-extensometry and tensile fracture of double edge-notched tensile specimens have been used to evaluate the Young's modulus at three different strain rates and the total work of fracture toughness at three different notch lengths. The polymer composite was analyzed by differential scanning calorimetry, thermogravimetric analysis, polarizing optical microscopy, wide angle x-ray diffraction, and transmission electron microscopy. 3% and 5% clay systems at various compatibilizer (PPMA) loadings were prepared by three different mixing routes for the isotropic sheets, produced by compression moulding, and tensile bars, produced by injection moulding process. Die-drawn oriented tensile bars were drawn to draw ratio of 2, 3 and 4. The results from the Queen's University Belfast samples showed a decrement in tensile strength at yield. This might be explained by poor bonding, which refers to poor dispersion. Voids that can be supported by intercalated PP/clay phases might be responsible for improvement of elongation at break. The use of PPMA and an intensive mixing regime with a two-step master batch process overcame the compatibility issue and achieved around 40% and 50% increase in modulus for 3% and 5% clay systems respectively. This improvement of the two systems was reduced after drawing to around 15% and 25% compared with drawn PP. The work of fracture is increased either by adding nanoclay or by drawing to low draw ratio, or both. At moderate and high draw ratios, PPNCs may undergo either an increase in the size of microvoids at low clay loading or coalescence of microvoids at high clay loading, eventually leading to an earlier failure than with neat PP. The adoption of PPMA loading using an appropriate mixing route and clay loading can create a balance between the PPMA stiffness effect and the degree of bonding between clay particles and isotropic or oriented polymer molecules. Spherulites size, d-spacing of silicate layers, and nanoparticles distribution of intercalated microtactoids with possible semi-exfoliated particles have been suggested to optimize the final PPNCs property.

Abstract:

This thesis presents a model for the procedures of manufacturing Fused Filament Fabrication (FFF) components by calculating required process parameters using empirical equations. Such an empirical model has been required within the FFF field of research for a considerable amount of time and will allow for an expansion in understanding of the fundamental mathematics of FFF. Data acquired through experimentation has allowed for a data set of geometric characteristics to be built up and used to validate the model presented. The research presented draws on previous literature in the fields of additive manufacturing, machine engineering, tool-path programming, polymer science and rheology. Combining these research fields has allowed for an understanding of the FFF process which has been presented in its simplest form allowing FFF users of all levels to incorporate the empirical model into their work whilst still allowing for the complexity of the process. Initial literature research showed that Polylactic Acid (PLA) is now in common use within the field of FFF and therefore was selected as the main working material for this project. The FFF technique, which combines extrusion and Computer Aided Manufacturing (CAM) techniques, has a relatively recent history with little understood about the fundamental mathematics governing the process. This project aims to rectify the apparent gap in understanding and create a basis upon which to build research for understanding complex FFF techniques and/or processes involving extruding polymer onto surfaces.

Flow visualisation of layers formation in a 3-layers slide coating die, measurement of their thicknesses and interfacial and free surface flow instabilities." Thesis, University of Bradford, 2016. http://hdl.handle.net/10454/18262.

Full text

Abstract:

Coating onto a moving substrate several films simultaneously on top of each other is a challenging exercise. This is due to the fact, depending on operating conditions (thickness and velocity of individual layers and the physical properties of the coating fluids), flow instabilities may arise at the interfaces between the layers and on the top layer. These instabilities ruin the application of the final multi-layered coating and must be avoided. This research addresses this coating flow situation and seeks to develop guidelines to avoid these instabilities. Following a critical literature survey, this thesis presents a novel experimental method that visualises multi-layered coating flow down an inclined multi-slot die. The visualisation is obtained using a unique configuration including a high-speed camera, telecentric objective lens and illumination. The results show for a single layer, as the die angle and Reynolds number increases, the flow becomes more unstable and for a dual layer flow, as Re increases the peak to peak amplitude and the frequency decreases at the free surface and interface. The latter was unexpected and does not conform with existing literature. The triple layer results show either a monotonically increasing or increasing from first to second layer viscosity stratifications are the most stable flows along with flow heights in the first and second layers of <22% and >18% of the total thickness respectively, which concur with current literature. The visualisation additionally obtained other instabilities including single layer back-wetting and vortices, and multilayer slot invasion with the findings concurring with current literature.

To attain this aim, a literature study was undertaken to: a) define and describe distance learning, b) describe the nature of learning, c) describe the nature of self-regulated learning and its implications for distance learning, and d) define and classify learning strategies and indicate the relationships between self-regulated learning, the use of learning strategies, and successful learning. Literature indicated a positive relationship between self-regulation, the use of learning strategies, learning success, and academic achievement: learning success results whenever pre-formulated learning goals are attained through the use of self-regulation and applicable learning strategies; and attainment of learning goals results in positive academic achievement. Self-regulated learners, who plan their learning, formulate learning goals, motivate themselves intrinsically, instruct themselves, apply different learning strategies to attain learning goals, continuously monitor and self-evaluate themselves during the learning process, are able to attain the formulated learning goals successfully and perform well academically. The literature review also revealed a high level of self-regulation as one of the prerequisites for performing successfully as a distance learner. Planning personal learning goals, using a variety of learning strategies to attain the goals, determining the correct personal learning tempo, monitoring learning progress, and self evaluating learning outcomes are typical characteristics of self-regulation necessary for effective distance learning and academic progress. The population of the research includes the PU vir CHO - Open Learning Academy-learners registered for the Further Diploma in Educational Management, module PSD 511 (Teaching and Learning) in the North West region of South Africa. The total number of students attending the three contact sessions in September 2000 at five sentra in the North West Province, and who participated in the research, was 143. Three questionnaires were used to obtain personal information, as well as information regarding self-regulation in the learners, namely, a biographical questionnaire, the Motivated Strategies for Learning Questionnaire (MSLQ) and the Self Regulated Learning Questionnaire (SRLQ). The data was statistically analized by means of: a) factor analyses, b) multiple regression analyses, and c) stepwise regression analyses. A difference was found to exists between the variables that determine the academic achievement of successful versus unsuccessful distance learners. Successful distance learners have better developed self-regulated learning skills than unsuccessful distance learners.

Abstract:

The conception of the unity of God in al-Juwayni, one of the latest thinkers in the early Islamic kalam, is the subject of this thesis. Al-Juwayni, though an Ash'arite thinker was quite often open to Mu'tazilite thought, particularly that of Abu Hashim al-Jubba'i. He was also influenced by the philosophers.
With al-Juwayni the kalam's theory of the unity of God reached its ultimate resolution. That is to say, the theory of the unity of God was based on specific epistemological grounds, in the early period of the kalam. It had assumed its shape, and was therefore open to the possibility for establishing a new approach to the unity of God in the ontological sense.
The first chapter deals with the long historical debate about the unity of God. It introduces many aspects of al-Juwayni's thought, and touches on how al-Juwayni proceeding from an Ash'arite background adopted many of the Mu'tazilite's themes, in its Basrian branch.
The second chapter analyzes the theory of al-Juwayni on these issues and shows his contribution to the notion of the unity of God in his book al-Irshad.
The third is a conclusion which throws light on the possibilities opened by al-Juwayni to approaching the unity of God from different ontological angles. Such possibilities had, infact, emerged in al-Juwaynis thinking when he began to use different concepts, particularly in his book al-'Aqidah al-Nizamiyah. Thus after he provided in al-Irshad that God is existence itself, he generally avoided using the terms atoms and accidents. Instead, he viewed the universe as two kinds, necessary Being and possible beings. In this context the attributes of God as aspects of His essence would play a different ontological role, comprehended in the term al-takhsid s.

Abstract:

This research is the first systematic investigation of solid-state orientation as a novel method for controlling drug release from biodegradable polymers. The effect of various degrees of polymer orientation was studied in oriented Poly (L-lactic acid) (PLA) films containing curcumin and theophylline as model drugs. Additionally, direction specific drug release was studied from oriented PLA rods containing paracetamol. The films oriented to 2X uniaxial constant width (UCW) or 2X2Y biaxial draw ratio showed retardation of drug release, when their nematic structure was stabilised by the presence of crystalline theophylline. Contrarily, the same films when contained solid solution of curcumin, shrunk in the release medium and exhibited a release profile similar to the un-oriented films. All films oriented to the UCW draw ratio ≥ 3X contained α crystalline form of PLA and showed acceleration of drug release proportionate to the draw ratio. According to the proposed mechanism augmented formation of water filled channels in these films was responsible for faster drug release. Similarly, the paracetamol loaded PLA rods die-drawn to uniaxial draw ratios ≥ 3X exhibited enhancement of drug release. Importantly, the amount of drug released along the oriented chain axis was significantly larger than that in the perpendicular direction. Drug release from the die-drawn rods was accelerated by a greater degree than that observed from the oriented films. This can be correlated to the differences in their size, geometry and the crystalline form of PLA. In conclusion, the current study provided substantial evidence that solid-state orientation can offer a control over drug release from PLA.

Abstract:

Trees are expected to modify their distribution and abundance in response to climate change with important consequences on forestry management practices and forest diversity. Whereas Species Distribution Models have been commonly used to relate known occurrence of species to the current climate as a first step to project future suitable environmental space, modeling abundance patterns using Species Abundance Models (SAMs) remains a challenge. This research aimed to: 1) evaluate the predictive performance of SAMs in predicting the current abundance of 105 tree species in eastern North America in response to climatic, topographic and edaphic predictors, and 2) explain the variation in SAMs' performance among species. The relative importance values of 105 tree species were first related to environmental predictors using Random Forest. The predictive performance of SAMs for each tree species was then assessed using the coefficient of determination (R²). Finally, multiple linear regression was performed to explain the variation in SAMs' performance among species (R²) using biogeographical and spatial attributes of species as explanatory variables. Predicting the current relative abundance of tree species using a combination of climatic, topographic, and edaphic variables was only partially successful. The coefficients of determination (R²) for all SAMs ranged from 0.000 to 0.857 with a mean of 0.258 and a standard deviation of 0.18. Black spruce (Picea mariana) had the best predictive model and Florida maple (Acer barbatum) the worst. Forty-one species out of 105 (39 %) had R² ≥ 0.3. These species had climate as the best and/or second best environmental predictor, except for Quercus macrocarpa, Pinus rigida, Pinus resinosa, and Ulmus alata, which were best predicted by non-climatic variables. The variation in the performance of SAMs among species was best explained by the range of relative abundance values and the spatial aggregation of species. This study highlighted the challenge in accurately predicting the relative abundance of trees in relation to current and therefore future climate, and identified species for which modeling approach worked best and for which abundance patterns would likely respond to climate change.
Les arbres sont susceptibles de modifier leur distribution et leur abondance en réponse aux changements climatiques avec d'importantes conséquences pour la gestion des ressources forestières et la biodiversité des forêts. Alors que les Modèles de distribution des espèces ont été couramment utilisés pour mettre en relation l'occurrence des espèces avec le climat actuel comme première étape dans l'évaluation des changements potentiels futurs, la modélisation des abondances à l'aide de Modèles d'abondance des espèces reste un défi. Cette recherche avait pour but : 1) d'évaluer la performance de modèles d'abondance pour prédire l'abondance relative actuelle de 105 espèces d'arbres de l'est de l'Amérique du Nord en réponse aux variables climatiques, édaphiques et topographiques, et 2) d'expliquer la variation entre les espèces dans les performances de ces modèles. L'importance relative des 105 espèces a d'abord été reliée aux variables environnementales à l'aide de l'algorithme mathématique Random Forest. La performance des modèles pour chaque espèce a été évaluée avec le coefficient de détermination (R²). Finalement, une régression linéaire multiple a servi à expliquer la variation des performances entre les espèces (R²) en utilisant les attributs biogéographiques et spatiaux des espèces comme variables explicatives. La prédiction de l'abondance relative des arbres avec les variables utilisées n'a été que partiellement réussie. Les coefficients of détermination (R²) allaient de 0.000 à 0.857 avec une moyenne de 0.258 et un écart-type de 0.18. L'épinette noire (Picea mariana) a montré la meilleure performance et Acer barbatum a obtenu la pire performance. Quarante et une espèces sur 105 (39 %) ont eu des R² ≥ 0.3. Ces espèces avaient le climat comme premier et/ou second prédicteur, sauf pour Quercus macrocarpa, Pinus rigida, Pinus resinosa, et Ulmus alata, qui ont répondu en priorité aux variables non-climatiques. La variation dans les performances des modèles entre espèces s'expliquent par l'étendue de leurs valeurs d'abondance relative et leur agrégation spatiale. Cette étude a démontré les limites à prédire l'abondance relative des arbres en fonction du climat présent et donc futur, et a permis d'identifier les espèces pour lesquelles l'approche de modélisation est possible et pour lesquelles l'abondance relative pourrait conséquemment être sensible aux changements climatiques.

Full text

Abstract:

This thesis is a study of 'Abd al-Jabbar's theory of i'jaz al-Qur'an (the miraculous inimitability of the Qur'an) as expounded in his magnum opus, al-Mughni fi abwab al-tawhid wa al-'adl, part XVI, and in his other works which are related to the subject. The importance of these works lies in the fact that the author was an erudite scholar and a respected leader of the Basra School of the Mu'tazila, and also because his Mughni/ is considered by many as the Encyclopedia of Mu'tazilite philosophy.
As a Mu'tazilite, 'Abd al-Jabbar demonstrates the inimitability of the Qur'an in the light of both his doctrine of mu'jiza (the apologetic miracle of a prophet) and khalq al-Qur'an (the createdness of the Qur'an). This thesis argues that although his theory of mu'jiza is incredibly similar to that of the Ash'arites, 'Abd al-Jabbar's rendering of it and his main sources are not the Ash'arites but rather the "School of Jubba'i"
Besides demonstrating the Qur'anic inimitability through kalam, 'Abd al-Jabbar also discusses its unsurpassable nature, in terms of the Holy Book's literary uniqueness, fasaha. This argument is distinctly different from the theories of his predecessors. As such, the thesis examines his predecessors' and contemporaries' works on i'jaz in order to shed light on the peculiarity of 'Abd al-Jabbar's theory.

O zinco ? um micronutriente importante para o crescimento das plantas, mas pode ser um problema quando presente em grandes quantidades, sendo a extra??o sequencial uma ferramenta promissora para se entender melhor o comportamento do Zn no solo. Objetivou-se com este trabalho observar o crescimento, a absor??o e o ac?mulo de Zn em cinco gram?neas forrageiras e entender o comportamento do Zn no solo ap?s o cultivo. Realizou-se um experimento em casa de vegeta??o em Latossolo Vermelho-Amarelo distr?fico. O delineamento foi inteiramente casualizado em esquema fatorial 5x4 com tr?s repeti??es, sendo os fatores: gram?neas forrageiras (Panicum maximum cv. Aruana e cv. Tanz?nia, Brachiaria decumbens cv. Basilisk, Brachiaria brizantha cv. Xara?s e cv. Marandu) e doses (0, 100, 300 e 900 mg kg-1 de Zn). O material vegetal coletado foi analisado separadamente, obtendo-se o peso de massa seca da parte a?rea, do coleto e das ra?zes e analisado o teor e ac?mulo de Zn em cada parte. Avaliou-se a disponibilidade de Zn atrav?s dos extratores Mehlich-1, DTPA a pH 7,3, USEPA 3051 e 3052 e o comportamento do Zn no solo foi avaliado atrav?s da extra??o sequencial do Zn analisando as fra??es troc?vel, ligada a carbonato, ligada a mat?ria org?nica, ligada a ?xidos, residual e total. As doses de Zn no solo provocaram redu??o de crescimento em todas as forrageiras avaliadas. Para a produ??o de massa seca a cv. Aruana foi a que mais produziu massa seca. Os maiores teores de Zn foram encontrados nas ra?zes da Tanz?nia e Marandu e na parte a?rea de Aruana, Xara?s e Basilisk. A ordem de acumula??o das forrageiras foram Aruana > Basilisk > Tanz?nia > Xara?s > Marandu. No geral a cv. Aruana se mostrou melhor para extrair Zn do solo. A ordem de extra??o foi DTPA a pH 7,3 < Mehlich-1 < USEPA 3051 < USEPA 3052, sendo que a metodologia USEPA 3051 mostrou resultados semelhante ao Mehlich-1, portanto eficiente em demonstrar a disponibilidade do Zn no solo. A distribui??o de Zn entre as fra??es no solo foi residual > carbonato > troc?vel > mat?ria org?nica > ?xidos.

Zinc is an important micronutrient to plant growth, but it can be problem when present in large amountsbeing the sequential extraction a promising tool to better understand the behavior of Zn in the soil. The objective of this study was to observe the growth, Zn absorption and accumulation in five forage grasses and to understand the behavior of Zn in soil after cultivation. We conducted an experiment in a greenhouse in Red-Yellow Dystrophic Latosol. The design was completely randomized in a factorial scheme 5x4 with three replicates, being the factors: forage grasses (Panicum maximum cv. Aruana e cv. Tanz?nia, Brachiaria decumbens cv. Basilisk, Brachiaria brizantha cv. Xara?s e cv. Marandu) and doses (0, 100, 300 e 900 mg kg-1 of Zn). The collected plant material was analyzed separately to obtain the dry matter weight of the shoot, the collar and roots and analyzed the content and Zn accumulation in each part. We evaluated the Zn availability using the extractors Mehlich-1, DTPA with pH 7,3, USEPA 3051 and 3052 and Zn behavior in the soil was evaluated by Zn sequential extraction analyzing the exchangeable fractions, linked to carbonate,to the organic matter and to oxides, residual and total. The doses of Zn in soil caused growth reduction in all forages. For dry matter production Aruana cv. was the one that most produced dry matter. The higher levels of Zn were found in the roots of Tanzania and Marandu and also in the shoots of Aruana, Xara?s and Basilisk. The order of accumulation of forage was Aruana > Basilisk > Tanz?nia > Xara?s > Marandu. Overall Aruana cv. proved to be the best to extract Zn from the soil. The order of extraction was DTPA with pH 7,3 < Mehlich-1 < USEPA 3051 < USEPA 3052, whereas the 3051 USEPA methodology showed results similar to Mehlich-1, therefore efficient in demonstrating the availability of Zn in soil. The distribution of Zn between fractions in the soil was residual> carbonate> exchangeable> organic matter> oxides.

Abstract:

Varje resa börjar och slutar på en station. Då tågresandet i Sverige under de senaste åren ökat och fortsätter att öka så spelar start- och slutdestinationen för resan en stor roll för hur tjänsten som helhet uppfattas. Järnvägsstationen är denna plats som kan komma att påverka främst resenärer, men även andra människor som vistas där, och deras uppfattningar om en tågresa. Med denna uppsats syftar vi därför till att ta reda på vad människorna i och runt järnvägsstationen påverkas utav, vad är viktigt på stationen, vad det är som gör att de trivs och vad kan göras för att de ska trivas bättre. Något som även kommer att undersökas är hur man på bästa sätt kan göra denna undersökning, vilken metod som lämpar sig bäst för just detta.

Enligt olika teorier, avhandlingar och undersökningar visade det sig att en kvantitativ metod med en enkätundersökning var det bästa alternativet för att nå syftet. Denna enkätundersökning utfördes på två i förväg bestämda järnvägsstationer och dessa belägna i Norrköping och Linköping. I den utförda enkätundersökningen såg vi vissa fördelar men även vissa nackdelar som kunde ha gjort enkätverktyget bättre.

Den genomförda undersökningen visade på en rad olika faktorer som påverkar resenärerna på järnvägsstationen. En punkt som kom att visa sig vara väldigt viktig, och samtidigt som var väldigt dålig på de båda stationerna var renligheten. Både renligheten gällande toaletterna men även stationens renlighet som helhet. Den här delen var något som visade sig påverka resenärens helhetsuppfattning om stationen, och något som även andra undersökningar och teorier har visat på. En annan aspekt som även det påverkade resenärernas helhetsuppfattning var beroende på vilket humör de var på. Det är dock svårt att göra någonting åt då humöret kan påverkas utav så många olika faktorer.

Resultatet av undersökningen visar att det finns ett antal olika förbättringsåtgärder både gällande enkäten som utformades, men även gällande resenärerna och vad som är viktigt för dem.

Abstract:

This thesis seeks to sketch the outer contours of the epistemological universe in which the science of us&dotbelow;ul al-fiqh was elaborated in classical Islam. The task is accomplished by analyzing arguments both for and against qiyas and ta`lil as presented by two major jurists of the 5th century of the Hijra representing opposite ends of the Islamic theological spectrum: (1) the H&dotbelow;anafite Mu`tazilite jurist Abu l-H&dotbelow;usayn al-Bas&dotbelow;ri (d. 436/1044) and (2) the Z&dotbelow;ahirite Abu Muh&dotbelow;ammad `Ali ibn H&dotbelow;azm al-Andalusi (d. 456/1064). After detailing each author's stance regarding the justifiability of qiyas and ta`lil, the thesis analyzes the underlying theological and epistemological premises and assumptions that can be extrapolated from each author's position. This analysis focuses on three fundamental sets of questions, namely: (1) What can be inferred from each author's position regarding the nature and provenance of knowledge in general, and of the relative status of certain (qat&dotbelow;`i, yaqini) versus suppositional (z&dotbelow;anni ) knowledge in matters of Shari`a? (2) What, according to each author, was the moral-legal status of acts before the promulgation of the Shari`a, and what can be inferred from this about the nature and provenance of moral-legal norms as conceived in the Islamic world view? Finally, (3) What can we conclude, on the basis of each jurist's arguments for or against qiyas and ta`lil, about the purposefulness of Divine acts in general and of the Shari`a in particular?

Im Kloster Altzelle an der Freiberger Mulde wurden nicht nur Bücher verwahrt und kopiert, Altzelle war ebenso ein Ort der Gelehrsamkeit, an dem auch neue Werke entstanden, wie vermutlich der zwischen 1220 und 1235 entstandene Urtext des Sachsenspiegels – wie wir erst seit Kurzem wissen. Es sprechen einige Indizien dafür, dass der Sachsenspiegel möglicherweise nicht – wie früher vermutet – auf der Burg Falkenstein im Ostharz oder in der Stiftsbibliothek von Quedlinburg, sondern in Altzelle geschrieben wurde. Mit dieser These sorgte der Münchner Rechtshistoriker Peter Landau bereits 2004 für eine regelrechte Sensation. Wichtige Argumente fand Peter Landau in der Altzeller Klosterbibliothek: Könnten doch alle im Altzeller Bücherverzeichnis von 1514 aufgeführten Werke, auf die sich Eike von Repgow im Sachsenspiegel bezog, bereits um 1220 in der Abtei vorhanden gewesen sein.

Abstract:

The goal of this research is to investigate the combined effects of glass fibre reinforcement and molecular orientation in polypropylene-short glass fibre composites. Specimens have been fabricated using the injection moulding process and drawn using a small die drawing rig. The effects of die drawing on the fibre composites are complex, with the drawing process orienting both the polymer molecules and the glass fibres. This may be accompanied by the creation of voids in the polymer matrix and their destruction in the compressive stress field thus restoring the interfacial contact area between fibre and matrix. Unfilled and short glass fibre filled polypropylene specimens, with fibre content 7% wt, 13%wt, 27%wt, and 55%wt, were injection moulded prior to the die drawing process. An experimental program of die drawing within an oven at elevated temperature was conducted for polypropylene filled to various levels and at different strain rates. The specimens drew to draw ratios in the range ¿=1.41 to ¿=5.6. Mechanical characterization of the test materials has been conducted by examining the tensile stress strain and fracture behaviour under uniaxial conditions. The influence of glass fibre content and drawing conditions (draw ratio) on the fracture toughness and crack propagation was investigated using the double edge notched fracture test. The notch lengths ranged from 1.5 to 2.5 mm for 10 mm wide specimens. The critical stress intensity factor increased as the fibre content increased up to a limiting filler level. The fracture toughness of both unfilled and fibre filled polypropylene were found to be highly dependent on draw ratio. The results were analysed to find out the optimal draw ratio and fibre content that yielded the maximum modulus, strength and fracture toughness. Data showed that, at a given draw ratio, modulus, strength and fracture toughness increased with increasing fibre content to a maximum and then decreased. The optimum material was obtained at a draw ratio of 2.5 and filler loading 13wt%.

Abstract:

This thesis applies interdisciplinary approaches to explore interactions between two forms of community governance in Acholiland from 1898 to 2010, locating itself within Peace Studies. One form, kaka, was “traditional”, featuring varied forms of “facultative mutualisms” among two or more gangi agnates – with one gang as dominant in the realm. Gangi were kinship-based polities. Like kaka, gangi manifested autopoietic attributes and strong internal “fiduciary cultures”. Then in the 1900s, kaka as governing systems were reshuffled under colonialism and a tribal unit, the Acholi Local Government was created and was subordinated to the Uganda state. Unlike kaka, Acholi Local Government was hierarchal and has consistently been redesigned by various postcolonial governments in their attempts to renegotiate, reshape and control the Acholi people. The study advances a concept of community governance as “socialpolitical” and moral, and counters that kaka was about brotherhoods - not rulersubject relationships. It further distinguishes what was “traditional” from “customary” systems, and demonstrates how colonialism in Acholiland, and a crisis of legitimacy manifested in a trifurcation of authorities, with: i) the despotic civil service - the “customary system”, fusing modernity and the African tradition, ii) a reshuffled kaka system as traditional, and, iii) the cross-modern, manifested as kinematic lugwok paco, linking ethno-governance with the nascent national and global arenas. The study concludes that both colonialism and “coloniality” have reshuffled the mores of kaka along an African neo-patrimonial legitimacy. Conversely, Acholiland is a “limited statehood” – manifesting a higher order of societal entropy - where the “rule by law and customs” dovetail with violence and poverty, demonstrating a genre of exceptionalism.

Abstract:

This study was undertaken in an attempt to determine the degree to which second year Mathematics education students consider critical thinking dispositions and attitudes to be important and to develop a curriculum-based mediational approach based on the data, to encourage the critical thinking dispositions and attitudes that appeared to be in need of encouragement. A literature study was undertaken to determine the positive critical thinking dispositions and attitudes students should possess. In addition it was also determined which teaching learning approaches will benefit the development of critical thinking dispositions and attitudes the most. The advantages as well as the processes and components that should form part of the mediational approach for the development of critical thinking dispositions were examined. A two-phase, sequential, explanatory mixed method study was subsequently undertaken with second-year Mathematics students at a South African university. The quantitative study made use of a self-developed questionnaire to determine the degree to which students consider critical thinking dispositions and attitudes important. Data emanating from the questionnaires were analysed and questions that had to be answered in narrative format were set for each student according to their own responses on the questionnaire. Narratives formed part of the qualitative component of the study in which students had to indicate factors that influence their critical thinking dispositions and attitudes, what could be done to improve the apparent unimportant critical thinking dispositions and attitudes and whether they regard the critical thinking dispositions and attitudes as important. Narratives were analysed and the results were used to explain the quantitative data. Results revealed that second year Mathematics education students do not consider critical thinking dispositions and attitudes, in particular inquisitiveness but also judiciousness, open-mindedness, systematicity, truth-seeking, analyticity and confidence in critical thinking to be very important and therefore these critical thinking dispositions and attitudes appeared to require encouragement. A curriculum-based mediational approach based on a section in the existing Mathematics module for second year education students was developed in order to encourage critical thinking dispositions in Mathematics. The study concluded with recommendations to encourage critical thinking dispositions and attitudes as well as proposals for future studies.

alities. The extensible Markup Language (XML) is used for data storage and message exchange, Extensible 3D (X3D) Graphics for visualization and XML Schema-based Binary Compression (XSBC) for data compression. The AUV Workbench provides an intuitive cross-platform-capable tool with extensibility to provide for future enhancements such as agent-based control, asynchronous reporting and communication, loss-free message compression and built-in support for mission data archiving. This thesis also investigates the Jabber instant messaging protocol, showing its suitability for text and file messaging in a tactical environment. Exemplars show that the XML backbone of this open-source technology can be leveraged to enable both human and agent messaging with improvements over current systems. Integrated Jabber instant messaging support makes the NPS AUV Workbench the first custom application supporting XML Tactical Chat (XTC). Results demonstrate that the AUV Workbench provides a capable testbed for diverse AUV technologies, assisting in the development of traditional single-vehicle operations and agent-based multiple-vehicle methodologies. The flexible design of the Workbench further encourages integration of new extensions to serve operational needs. Exemplars demonstrate how in-mission and post-mission event monitoring by human operators can be achieved via simple web page, standard clients or custom instant messaging client. Finally, the AUV Workbench's potential as a tool in the development of multiple-AUV tactics and doctrine is discussed.

Abstract:

The goal of this research is to investigate the combined effects of glass fibre reinforcement and molecular orientation in polypropylene-short glass fibre composites. Specimens have been fabricated using the injection moulding process and drawn using a small die drawing rig. The effects of die drawing on the fibre composites are complex, with the drawing process orienting both the polymer molecules and the glass fibres. This may be accompanied by the creation of voids in the polymer matrix and their destruction in the compressive stress field thus restoring the interfacial contact area between fibre and matrix. Unfilled and short glass fibre filled polypropylene specimens, with fibre content 7% wt, 13%wt, 27%wt, and 55%wt, were injection moulded prior to the die drawing process. An experimental program of die drawing within an oven at elevated temperature was conducted for polypropylene filled to various levels and at different strain rates. The specimens drew to draw ratios in the range γ=1.41 to γ=5.6. Mechanical characterization of the test materials has been conducted by examining the tensile stress strain and fracture behaviour under uniaxial conditions. The influence of glass fibre content and drawing conditions (draw ratio) on the fracture toughness and crack propagation was investigated using the double edge notched fracture test. The notch lengths ranged from 1.5 to 2.5 mm for 10 mm wide specimens. The critical stress intensity factor increased as the fibre content increased up to a limiting filler level. The fracture toughness of both unfilled and fibre filled polypropylene were found to be highly dependent on draw ratio. The results were analysed to find out the optimal draw ratio and fibre content that yielded the maximum modulus, strength and fracture toughness. Data showed that, at a given draw ratio, modulus, strength and fracture toughness increased with increasing fibre content to a maximum and then decreased. The optimum material was obtained at a draw ratio of 2.5 and filler loading 13wt%.
