Testo completoAbstract (sommario):
Now-a-days, the major challenge that’s being faced by the concrete industry is the cleaning of concrete handling equipment. Concrete consists of aggregates, which harden with time, and the transportation of concrete mixture within the plant is a significant problem. This will not only increase the overall maintenance cost, but will lead to loss of raw materials, affect the rate of production, and reduce the lifetime of concrete handling equipment.
The present study focuses on the design and implementation of an adaptive cleaning mechanism in the concrete industry and its importance in achieving efficient cleaning, which is tested to verify its performance in the Paver production plant. The goal of this study is to provide practical evidence about the importance of adaptive cleaning mechanisms for industrial applications.
The first chapter gives a detailed introduction about pavers and the production process, the cause of material loss that occurs during transportation of wet concrete mixture inside a paver plant, and its effect on handling equipment and work environment. The second chapter explains design and working of the paver machine push bar mechanism, which can be implemented in a hydraulic press production process of pavers. The third chapter includes analysis and results of the mechanism obtained using Solidworks and Autodesk Inventor followed by observations that are achieved based on practical application of this mechanism in a paver production plant.

Testo completoAbstract (sommario):
The growth in the international usage of flexibly bedded pavers since World War II has brought about the need fully to understand how pavers bedded in sand function. The design methods are based upon the concept of making pavers and their bedding sand equivalent to conventional pavement construction materials. Experience has shown that pavers do not behave as a collection of individual units but rather interlock so that they behave in a manner close to that of flexible materials. The nature of a pavement surfaced with pavers is therefore depending on the pavers, the joints, and the way in which the two relate as well as the foundation on which the pavers rest. In this Thesis, a way in which pavers distribute stresses resulting from rolling loads has been investigated and an understanding of the interlocking process thereby developed. This Thesis explains the theoretical analysis and demonstrates how it can be used to establish the nature and value of interlock. Chapter 1 concentrates on this process by starting to introduce concrete paver pavements and goes on outlining the principles upon which the remainder of this Thesis is based. The achievement of full interlock in the surface level of a paver pavement is an essential part of any successful paver pavement. It is important to understand the principles and specifications for the materials and construction process in order to satisfy the requirements of paver pavement components. Because of this reason, Chapter 2 outlines the major contents of UK specifications for the materials and construction methods likely to be used for the construction of paver pavements. Chapter 3 is concerned with the existing structural design of concrete paver pavements carrying vehicular traffic ranging from trucks to heavy industrial vehicles and aircrafts. Design criteria for such pavements are established and a range of methods for their analysis and design are reviewed. Chapters 4 and 5 show how the variations of patch loading on the surface of pavers can be calculated. Chapter 6 presents the bedding sand stress calculation method which can be used to determine the patterns of stress within the bedding material and it shows how these patterns develop as a patch loading rolls across pavers. All possible eccentric load patches on the surface and their all vertical compressive stress distributions in bedding sand were calculated for chamfered rectangular pavers (with and without interlock), non-chamfered rectangular and nine proprietory shaped pavers. The nine proprietory shaped pavers analysed in this Thesis are commercially important on a worldwide basis. Chapters 7,8 and 9 explains how the bedding sand stress calculation method can be applied to proprietory shaped pavers. A common proprietory shaped paver has been selected as an example in Chapter 7 to show how all possible vertical compressive stress regimes of proprietory shaped pavers can be calculated for all realistically possible load patches. The remaining proprietory shaped pavers are analysed in Chapter 8. The results of the analyses presented in Chapters 5,7 and 8 are shown in Chapter 9. The results are being used in the development of paver jointing systems and it is now possible to assess more effectively the tolerances required in paver installation. Although paver pavements appear to be very simple structures they are in reality very complicated, possibly one of the most complicated of all civil engineering structures. In order to predict the future performance of paver pavements, a vast number off simplifications must therefore be made. One of the most promising approaches to this is to apply accurate modelled Finite Element Analysis obtaining the data related with systematic behaviour of paver pavements on the surface level from the results of this Thesis.

Orientador: Cesar Fabiano FioritiResumo: O crescimento da população e do seu poder aquisitivo mudaram a geração de resíduos. Atualmente se produz resíduos diferentes em qualidade e volume diferentes daqueles produzidos por gerações passadas. Entre os resíduos gerados atualmente se encontram os resíduos de PET, oriundos de embalagens descartáveis, que acarretam problemas ambientais devido ao descarte incorreto. Este trabalho se propõe em estudar a aplicação destes resíduos para a produção de pavers de concreto, observando suas características de desempenho em relação aos pavers produzidos com concreto convencional, ambos produzidos por procedimentos manuais. Para atingir o objetivo proposto foram realizados ensaios de trabalhabilidade, ensaios de massa específica em estado fresco e endurecido, ensaios de absorção de água, medição da incorporação de ar, ensaios de resistência à compressão, tração e impacto e microscopia eletrônica de varredura para os traços produzidos com 5%, 10%, 15% e 20% de substituição em volume dos agregados miúdos e graúdos. Dessa maneira, foi possível buscar informações a respeito do comportamento obtido por meio da substituição parcial dos agregados pelos resíduos de PET produzindo peças com características semelhantes àquelas proporcionadas pelos pavers convencionais, atingindo a resistência à compressão de 35 MPa, definida em norma, em 4 traços produzidos, mesmo com valores de absorção superiores aos 6% estipulados em norma.
Abstract: Population growth and purchasing power changed waste generation. Currently the wastes produced differs in quality and volume than that produced by past generations. Amongst the waste currently produced are the PET waste, originating from disposable packaging, which generate environmental problems due to incorrect disposal. The purpose of this work is to study the application of these residues in concrete pavers production, observing the performance characteristics in comparison to those produced with conventional concrete, both produced by manual procedures. To achieve the proposed goal were performed workability tests, specific weight in both fresh and hardened conditions, water absorption tests, air content tests, compressive strength, splitting tensile strength and impact tests and scanning electron microscopy for the concrete designs containing 5%, 10%, 15% and 20% by volume of both fine and coarse aggregate. Thus, it was possible to achieve information about the concrete behavior produced with partial substitution of the aggregates by the PET waste, producing pavers with similar characteristics of those provided by pavers produced with conventional concrete, achieving the compressive strength of 35 MPa, required by standard, in 4 mixtures with substitution, although the absorption values were above the 6% required by standard.

What in fact is an author?s style? It is the point of view from which an
author sees the given subject. Which style he uses when recording the
action, to which extent he enters into it and tries to influence it, what shooting angles and image interpretation he uses, in what way he works with sound. We can agree upon the fact that only few directors have such a distinct and characterful author?s style as Pavel Koutecký does. He was a director always searching for new possibilities and forms of artistic expression. In my diploma paper I survey his fundamental films and give a general overview of his work.

Testo completoAbstract (sommario):
Firefighters and asphalt pavers are exposed to polycyclic aromatic hydrocarbons (PAHs) during various work activities. The purpose of this study was to evaluate urinary PAH levels and compare these bio-monitoring levels among firefighters, asphalt pavers, and non-occupationally exposed individuals. The National Institute of Standards and Technology (NIST) urinary PAH levels were used for non-occupationally exposed controls. When compared to the NIST standard for smokers and non-smokers, firefighters demonstrated statistically significant differences in urinary concentration differences for the following metabolites: 2-OH-fluorene, 3-OH-fluorene and 1-OH-pyrene, which were lower in firefighters than the NIST mean for smokers. 1-OHphenanthrene, 2-OH-phenanthrene and 3-OH-phenanthrene were higher among world trade center exposed firefighters than the NIST mean for smokers. When firefighters were compared to the NIST non-smoker standard, firefighters demonstrated elevated levels in all tested PAH biomarkers due to a mixture of smokers and non-smokers in the firefighter cohort.
Asphalt workers had statistically significant higher urinary concentration elevations in 2OH-fluorene, 1-OH-phenanthrene and 3-OH-phenanthrene as compared to the NIST smoker mean. When asphalt pavers were compared to the NIST non-smoker mean, asphalt pavers had statistically significant increases in all tested PAH biomarkers, with the exception of 2-OHphenanthrene. While firefighters did not demonstrate a substantial change in urinary PAH metabolite levels compared to control populations of smokers and non-smokers, asphalt pavers experienced concentrations that were in some cases increased by orders of magnitude compare to NIST controls. Future research may be needed to evaluate any potential health risk posted to occupational exposed asphalt pavers.

CAPES
Peças de concreto intertravadas para pavimentação (pavers) coloridas com pigmento de óxido de ferro (vermelho) são utilizadas em projetos de urbanização. Entretanto, esse tipo de pigmento, além de encarecer de 20 a 30% o valor das peças, prejudica as propriedades dos concretos secos moldados sob vibrocompressão. Diante disso, propõe-se incorporar resíduo de cerâmica vermelha (RCV) como matiz colorimétrica em prol da redução de pigmento em pavers coloridos, tendo em vista também a possibilidade de melhoria de suas propriedades por efeitos filler e pozolânico. A fim de investigar o efeito do pigmento e do RCV no compósito estudado, as formulações foram: (a) traço padrão pelo método de dosagem da ABCP para blocos e pavers; (b) adição de pigmento ao traço padrão (2% e 4%); (c) substituição da areia média pelo RCV no traço padrão (50%, 75% e 100%); (d) adição de RCV ao traço padrão (20%, 30%, 40% e 50%); (e) adição de pigmento (2%) e RCV concomitantemente ao traço padrão (20%, 30%, 40%, 50%, 100% e 150%). Para todos os traços (exceto aqueles das formulações de substituição), foi feita a correção do consumo de cimento em relação ao traço padrão. Resistência à compressão, absorção de água e resistência à abrasão foram avaliadas de acordo com a norma NBR 9781:2013; além disso, foi realizada uma avaliação das cores dos compósitos desenvolvidos por inspeção visual. Pastas de cimento vibroprensadas com baixa relação água-cimento (padrão, 3% pigmento, 15% RCV e 3% pigmento – 15% RCV) também foram moldadas para avaliações de cunho microestrutural, cristalográfico e de análise térmica das reações de hidratação dos sistemas. O traço padrão foi 1:2,29:1,76:0,95 (cimento:areia média:areia muita grossa:pedrisco) com relação água-materiais secos 0,80. De uma maneira geral, adições de apenas pigmento (2% e 4%) reduziram em até 73% a resistência à compressão do paver padrão cinza (sem adições). Redução nos produtos de hidratação (CH e C-S-H) foram observadas. As substituições de areia média pelo RCV também foram prejudiciais a esse sistema. Já as adições de apenas RCV, bem como as de RCV concomitantemente com pigmento foram positivas em ganhos ou manutenção de propriedades (resistência à compressão, absorção de água, resistência à abrasão e cor) em relação ao paver padrão colorido (4% de pigmento), destacando-se a formulação 2% de pigmento e 50% de RCV. Assim, a adição de RCV é uma possibilidade técnica promissora, sustentável e economicamente viável na fabricação de pavers avermelhados.
Concrete interlocking blocks colored with pigment iron oxide (red) are used in urbanization projects. However, that kind of pigment increases around 20 to 30% the value of the pavers, as well as affect the properties of the dry concrete molded by vibrocompression. Therefore, it is proposed to incorporate red ceramic waste (RCW) as colorimetric hue in order of pigment content reduction in colored pavers, considering also the possibility of improving their properties by filler and pozzolanic effect. In order to investigate the effect of pigment and RCW in the studied composite, the formulations were: (a) reference paver designed by ABCP method for blocks and pavers; (B) adding pigment to the reference paver (2% and 4%); (C) substitution of medium sand by RCW in the reference paver (50%, 75% and 100%); (D) adding RCW in the reference paver (20%, 30%, 40% and 50%); (E) addition of pigment (2%) and RCW concurrently in the reference paver (20%, 30%, 40%, 50%, 100% and 150%). For all mixtures (except those of replacement formulations), it was made the correction in cement consumption related to the reference mix proportion. Compressive strength, water absorption and abrasion resistance were measured according to the ABNT NBR 9781: 2013 standards; besides that, the color and texture of all manufactured formulations were observed by visual inspection. Cement pastes made by vibrocompression with low water-cement ratio (reference paste, 3% pigment, 15% RCW and 3% pigment RCW - 15% RCW) were also molded for microstructural, crystallographic and thermal analysis of systems hydration reactions. The reference mix proportion was 1:2.29:1.76:0.95 (cement: medium sand: thick sand: gravel) with ratio water-dry material 0.80. In general, additions of only pigment (2% and 4%) up to 73% reduced the compressive strength of the reference paver (no additions). Reduction in hydration products (C-S-H and CH) was observed. The substitution formulations of medium sand by RCW were also harmful to the systems. Additions of only RCW and RCW concomitantly with pigment were positive in gains or maintaining of properties (compressive strength, water absorption resistance and abrasion resistance) compared to the reference colored paver (4% pigment), especially the formulation of 2% pigment and 50% RCW. Thus, the addition of RCW is a promising, economic and sustainable technique in the production of red pavers.

La ville de pavie a ete le siege de l'une des premiere experiences italiennes de creation de structures institutionnelles visant a favoriser la participation des citoyens a la vie publique. L'enthousiasme et les ambitions avec lesquels elle fut concue au debut des annees 70 ont depuis longtemps laisse la place a l'insatisfaction unanime des acteurs politiques et sociaux concernes. Cette these se propose d'etre un instrument pour aller au-dela d'un debat qui tend a s'exprimer exclusivement en termes de responsabilites subjectives. En cette perspective, on y analyse: la relation entre la nature de la mobilisation sociale spontanee et la qualite des structures participatives; la pratique de la participation par rapport aux contenus des politiques sociales et de la planification urbaine; l'impact sur l'experience pavoise des changements institutionnels qui interviennent au fur et a mesure au niveau national; les changements sociaux et demographiques, et les transformations culturelles qui leur sont liees. Cette approche permet de montrer comment les formes de participation actuelle ont desormais epuise leur tache, et de definir un modele alternatif approprie au niveau contexteThe city of pavia was one of the first italian cities to provide an institutional structure for community participation in local decision making. When this structure was devised in the 1970's there was great enthusiasm about the idea and great expectations regarding its practical application. This thesis attempts to provide a way to go beyond a debate which tends to express only subjective responsability, by examining the objective factors in play. In this context the following are analyzed: the relationship between the nature of spontaneous social mobilization and the quality of the community structure; the practice of community democracy in relationship to the contents of social politics and urban plnning; the impact of various institutional changes at national level on the pavia experience and finally social and demografic changes together with the cultural changes connected with them. Using this approach it is shown that the currently existing forms of participation have outlived their function and a new, more adeguate model is proposed. However, by now the political and social actors involved in the structure feel frustated by it

Geotextiles have been widely promoted for pavement structure over the past 30 years. However, there is a lack of well-instrumented, full-scale experiments to investigate the effect of geotextile reinforcement on the pavement design. In this study, full–scale accelerated tests were conducted on eight lanes of pavement test sections. Six out of these eight sections had granular bases reinforced with different types of woven geotextiles. The reinforced base sections and the control sections (with unreinforced base) were paved with Superpave hot-mix asphalt. Base and subgrade materials were the same for all sections while the test sections had different asphalt and base layer thicknesses. Each section was instrumented with two pressure cells on top of the subgrade, six strain gages on the geotextile body, six H-bar strain gages at the bottom of the asphalt layer, two thermocouples and one Time Domain Reflectometer (TDR) sensor. The sections were loaded to 250,000 to 500,000 repetitions of an 80-kN single axle load of the accelerated pavement testing machine. The mechanistic response of each section was monitored and analyzed at selected number of wheel passes. Results indicate that properly selected and designed geotextile-reinforced bases improve pavement performance in term of rutting and reduced pressure at the top of the subgrade. Finite element (FE) models were developed and verified using results from the full-scale accelerated pavement tests. The calibrated model was used to investigate the effects of geotextile properties on the pavement responses. FE analysis shows that benefits of reinforcement are more evident when stiffer geotextile is used.

Geocellular confinement systems (geocells), three-dimensional honeycomb-like structures containing an infill of available materials such as sand or crushed limestone, vastly improve shear strength of infill materials. Geocells are potential solutions for challenges associated with low-volume paved road reconstruction. The objectives of this study were to test geocell designs with various infill materials and a thin hot-mix asphalt overlay under full-scale traffic load and to numerically model this problem. Therefore, eight pavement test sections were constructed at the Civil Infrastructure System Laboratory at Kansas State University, Manhattan, Kansas. Repeated loads (80-kN, single axle) were applied to the pavement sections using an accelerated pavement testing machine till failure. Pavement sections were modeled three-dimensionally using Abaqus, a commercially available finite element software package. Effects of geocell height and location were simulated in the geocell-reinforced bases, and pavement structures were modeled as three-layered systems. Results showed that proper geocell height, infill material and cover depth to protect the geocells during construction are necessary to ensure long-term performance of geocell-reinforced pavements. Such pavement structures with low- quality infill materials can perform as well as conventionally-constructed pavement structures.

Čurda, Martin. "Analytical and hermeneutical perspectives on the music of Pavel Haas". Thesis, Cardiff University, 2017. http://orca.cf.ac.uk/100017/.
Testo completoAbstract (sommario):
The Czech composer Pavel Haas (1899–1944) is commonly positioned in the history of twentieth-century music as a representative of Leoš Janáček‘s compositional school and as one of the Jewish composers imprisoned by the Nazis in the concentration camp of Terezín (Theresienstadt). However, the nature of Janáček‘s influence remains largely unexplained and the focus on the context of the Holocaust tends to yield a one-sided view of Haas‘s oeuvre. The existing scholarship offers limited insight into Haas‘s compositional idiom and does not sufficiently explain the composer‘s position with respect to broader aesthetic trends and artistic networks in inter-war Czechoslovakia and beyond. The purpose of this thesis is to enhance the knowledge and understanding of Haas‘s music through analytical and hermeneutical interpretation as well as cultural and aesthetic contextualisation, and thus reveal the rich nuances of Haas‘s multi-faceted work which have not been sufficiently recognised so far. Following a survey of Czech inter-war avant-garde discourse, undertaken in Chapter 1, I argue in Chapter 2 that Haas‘s works from the 1920s were profoundly influenced by the Czech avant-garde movement known as Poetism. In Chapter 3, I discuss the emergence of Neoclassical tendencies in Haas‘s music from the 1930s. In Chapter 4, I analyse Haas‘s compositional language through Janáček‘s notion of ‗sčasování‘, focusing particularly on the relationship between rhythm and form. Chapter 5 looks into Haas‘s enigmatic opera Charlatan from the perspective of literary types and genres, questioning its relevance to the impending horrors of Nazism. The final chapter explores the portrayal of troubled subjectivity in Haas‘s song cycle from Terezín. Throughout the thesis, I discuss the composer‘s fascination with the recurrent topoi of carnival and the fairground, as well as his preoccupation with semantic ambiguity resulting from ironic subversion of meaning, grotesque exaggeration and distortion, and collage-like juxtaposition of incongruous elements.

Olamide, Ibrahim Nurudeen. "Paved with good intention? The African Union counter terrorism agenda". Diss., University of Pretoria, 2012. http://hdl.handle.net/2263/36787.
Testo completoAbstract (sommario):
Africa has for a long time been embattled by differing acts of terrorism, with divergent
manifestations such as suicide bombing, killings and hijacking. Accordingly, the
Organisation of African Unity and subsequently the African Union took up the
responsibility of developing strategies to counter the menacing trend of terrorism on
the continent. To this end, several counter terrorism interventions were created. The
first of Africa's interventions was developed as early as 1992, when the Organisation of
African Unity (OAU) member states adopted a Resolution to strengthen cooperation
and coordination among African states against different manifestations of extremism.
Although, there is abundance of scholarly literature on the subject of understanding of
terrorism and its human rights implications and also on the impact of terrorism on
political pluralism, there is a dearth of scholarly writings on the activities of the African
Union in relation to terrorism in Africa, particularly on whether the Union is
responding positively to its counter terrorism agenda. Yet, the role of the African Union
in this regard on the continent cannot be over emphasised. This study is therefore carried out to scrutinise the counter terrorism agenda of the African Union and explore
its counter terrorism activities from inception till date.
In ascertaining the necessity for the African Union to develop ways to adequately
implement its counter terrorism agenda, the study carries out an assessment of the
agenda and established its link with the United Nations counter terrorism framework.
Recommendations about how best the agenda can be realised concludes the study.
Specifically, the research explores the activities of the African Union with the aim of
determining whether the agenda was merely paved with good intentions.
While many weaknesses of the agenda were discovered and discussed in depth, the
research concludes, that despite the gap that exists between the agenda and its
implementation and the problem of resources bedevilling the implementation of the
agenda, it will be unfair to describe the African Union counter terrorism agenda as
merely paved with good intentions in the lights of numerous positive steps that have
been taken towards translating the agenda into full implementation.Dissertation (LLM)--University of Pretoria, 2012.

The production of waste from urban and industrial activities is one of the factors of environmental contamination and has aroused attention of the scientific community, in the sense of its reuse. On the other hand, the city of Salvador/Ba, with approximately 262 channels, responsible for storm water runoff, produces every year, by the intervention of cleaning and clearing channels, a significant volume of sediments (dredged mud), and thus an appropriate methodology for their final destination. This study aims to assess the influence of incorporation of these tailings in arrays of clay for production of interlocked block ceramic, also known as ceramic paver. All the raw materials from the metropolitan region of Salvador (RMS) were characterized by x-ray fluorescence, x-ray diffraction, thermal analysis (TG and TDA), particle size analysis and dilatometry. With the use of statistical experimental planning technique, ternary diagram was defined in the study region and the analyzed formulations. The specimens were prepared with dimensions of 60x20x5mm?, by uniaxial pressing of 30 MPa and after sintering at temperatures of 900?, 1000? and 1100?C the technological properties were evaluated: linear shrinkage, water absorption, apparent porosity, apparent specifies mass, flexural rupture and module. For the uniaxial compression strength used cylindrical probe body with ? 50 mm. The standard mass (MP) was prepared with 90% by weight of clay and 10% by weight of Channel sediment (SCP), not being verified significant variations in the properties of the final product. With the incorporation of 10% by weight of manganese residue (PFM) and 10% by weight of the Ceramic waste (RCB) in the mass default, in addition to adjusting the plasticity due to less waste clay content, provided increased linear firing shrinkage, due the significant concentration of K2O, forming liquid phase at low temperature, contributing to decreased porosity and mechanical resistance, being 92,5 MPa maximum compressive strength verified. After extract test leachate and soluble, the piece containing 10% of the PFM, was classified as non-hazardous and inert material according to NBR10004/04 ABNT. The results showed the feasibility on using waste, SCP, RCB and PFM clay mass, at temperatures above 900?C, paver ceramic production, according to the specifications of the technical standards, so that to exceed the 10% of the PFM, it becomes imperative to conduct studies of environmental impacts

Testo completoAbstract (sommario):
This study investigates product development of complex products in a modular environment at the paver manufacturer Dynapac. It is determined how the complexity of a modular product constrains product development.Product development in a modular enviornment is a popular research topic in previous literature. However there is limited literature regarding in what ways the complexity of a modular product constrains product development in form of new product variants demanded by the market. A more comprehensive research within this field is interesting for manufacturing companies producing complex products in a modular environment since it could ease and optimize their product development processes. An efficient product development process is crucial to stay competitive and to be able to serve the market rapidly with qualitative and desired products, which increases the importance of this study.With the aim to address the limitations of the existing literature on product development based from modular complex product systems a case study was conducted. The constraints of developing a new paver model demanded by the market caused by the complexity of the paver design were identified.The findings of the research have both theoretical and managerial implications. The theoretical contribution consists mainly of the identification of a new type of overall constraints in modular complex product systems which I call ‖architectural functional constraints‖. These constraints cause an unexpected chain reaction of affected modules in the product system when a change to one module is made, even if the change ostensibly only should affect the module in question. The results show that the effects of this type of constraints is a constraining factor on product development of new product variants in a modular environment. The effects of the architectural functional constraints constrain product development since they trigger time consuming activities in order to avoid a dysfunctional product, or a product that has a high level of commonality with other product offerings. Further the effects oppose a rapid and cost-efficient product development which is regarded to be two of the main benefits with modularity.The managerial implications include a decision process for new product development projects that can be used when architectural functional constraints are found in a product in order to ensure an economic sustainable development of new product variants. Hence managers can use the decision process as a tool to both make and communicate current and future decisions in a structured way.The study is a starting point for further studies investigating how the complexity of modular products might constrain product development efforts. It is expected that the results of the study can be used by other manufacturing companies operating in a similar context, producing complex product systems in a modular environment.

Mänskliga handlingar förstör dagligen planeten vi bor på, men trots att vi numera är medvetna om problematiken görs det ändå inte tillräckligt för att förändra detta beteende. Undervisningen i den svenska skolan syftar bland annat till att främja elevernas respekt för miljön och visa dem ett hållbart levnadssätt. Syftet med denna uppsats är att utvärdera potentialen hos ett arbetssätt som kombinerar svenskämnets läsning av skönlitteratur med miljöfrågor. Med hjälp av begreppen ekocentrism och antropocentrism gör vi en ekokritisk läsning av Michelle Pavers Vargbröder. Utdrag ur boken används också som grund för att diskutera hållbar utveckling med en klass elever i årskurs 6, för att se vilka värderingar som framträder. Resultatet visar att det finns stor potential att öka elevers ekolitteracitet med hjälp av gruppdiskussioner och ekokritiska resonemang utifrån en skönlitterär bok, men att arbetssättet kräver mycket tid och vidare forskning. Eleverna visar ett stort intresse för läsningen och för frågorna, och även om deras konkreta kunskaper brister en del, visar de att de tycker att det är viktigt att människan tar hand om vår planet.

Testo completoAbstract (sommario):
The sources of the theories underlying Czech Cubist architecture before World War I have been only sketchily studied to date. To analyze these theories and identify their sources, I focus on the work of architect and theorist Pavel Janak (1882-1956), an early proponent of Cubist architecture in Bohemia. The thesis incorporates my translation of Janak's unpublished journal for 1911-1914, the dominant years of Czech Cubism. Through this journal and Janak's published writings, together with an examination of his own readings, I trace the development of his theories, and situate his sources, within their historical context. Janak was no mere imitator of French Cubism but was concerned to develop innovative architecture that yet possessed both historical continuity and universal validity, thanks to its space-creating qualities.The thesis includes a facsimile of Janak's journal with its numerous sketches, a translation en face, and a complete bibliography of his sources.

Transportation agencies report the localization of roadway anomalies that could cause serious hazards to the traveling public. However, the high cost and limitations of present technical prevent scaling the road monitoring to all roadways. Especially the unpaved road, because of the complexity of unpaved road. Using smartphone application as road condition data collection tool offer an attractive alternative because of its potential to monitor all roadways in real time and its low cost. However, the sensor sensitivity and sampling frequency of different smartphones may vary significantly, which challenge the confidence of using smartphones for actual pavement condition assessment applications. This study tends to solve this challenge by calibrating different smartphones using two different calibrating methods including calibrating towards reference or average road roughness.

Testo completoAbstract (sommario):
Pavel A. Florensky (1882-1937), considéré comme un des plus grands "philosophes religieux" russes, a abordé des questions théologiques d'un grand intérêt en faisant converger sa propre expérience spirituelle, ses larges connaissances scientifiques et la Tradition de l'Église d'Orient. Après une biographie qui fournit l'horizon de l'œuvre de l'auteur, la thèse en histoire des religions affrontera la pensée de Florensky dans ce qui la rend actuelle : comment se situe, du point de vue de la connaissance du mystère de Dieu, l'expérience personnelle et le langage symbolique dans la théologie orthodoxe. Ce qui est en jeu, c'est le fondement et la possibilité de cette connaissance dans l'expérience et son expression par le symbole. L'intuition de Florensky est que, plus que "définir" l'objet de la connaissance, le langage symbolique l'indique, ou mieux, invite l'homme à entrer en relation personnelle avec le mystère afin que Dieu puisse s'y révélerPavel A. Florenskij (1882-1937) is one of the greatest of Russian "religious philosophers". He discussed theological questions of burning interest and brings together his own spiritual experience, his wide scientific knowledge and the Tradition of the Orthodox Church. After giving an account of his life, to provide the background to his work, the thesis is a study of those qualities of Florenskij's thought that are of contemporary relevance: with regard to the knowledge of the mystery of God, where does one place personal experience and symbolic language in orthodox theology. What is at stake here is the foundation and the possibility of this knowledge in experience and its expression in symbol. Florenskij's intuition is that rather than "defining" the object of this knowledge, symbolic language indicates it, or better than this, it invites man to enter into a personal relationship with the mystery so that God can reveal himself through this

While the design and the technology behind the vehicles we drive has gone a long way, the main principle in which we construct our roads today, the materials and the machinery we use to do it has hardly changed for the last 40 years.This project takes a fresh look at an industry that has remained stagnant for several decades. Looking into a future in which large Mega-Cities will develop, the aim of this project will be to develop a new solution for constructing and maintaining the transport arteries in those cities. This project was performed in collaboration with Dynapac, a leading manufacturer of road construction equipment, with supporting feedback from NCC roads, the Scandinavian road construction group.

Testo completoAbstract (sommario):
Cette thèse sur la poésie religieuse d’Ennode de Pavie (473/4-521), homme d’Église et homme de lettres de l’Antiquité tardive, vise à un double objectif. D’une part, proposer la première traduction française de l’ensemble des épigrammes et des hymnes que l’auteur composa pour l’Église ambrosienne durant son diaconat à Milan. Il n’existait en effet à ce jour qu’une traduction partielle en italien, du reste fondée sur le texte latin édité par F. Vogel à la fin du xixe s. Or ce dernier ne prend donc pas en compte les témoins manuscrits de l’ensemble des opera de l’auteur découverts récemment, ni les nombreuses attestations isolées de trois de ses hymnes, jamais recensées ni étudiées jusque-là, qu’on trouve dans divers livres liturgiques copiés entre le xie et le xve s. En Italie du Sud, entre autres. D’autre part, procéder à une étude thématique et esthétique exhaustive de ses carmina religieux, d’ordinaire assimilés à ses poèmes mondains, et frappés du même discrédit qu’eux en raison de leur écriture maniérée jugée vaine et source d’obscurité. Une telle assimilation est néanmoins réductrice, car les tituli et les hymni en question, en prise, de deux manières distinctes, avec la vie spirituelle milanaise, témoignent d’un réel engagement de la part d’Ennode au service de son Église : en s’effaçant derrière l’évêque alors en place, dont il était le porte-parole, il s’est fait le chantre officiel de l’Église de Milan qui, à la faveur de la paix retrouvée, aspirait alors à renouer avec son illustre passé ambrosienThis PhD thesis on the religious poetry of Ennodius of Pavia (473/4-521), man of Church and man of letters from the late Antiquity, consists of a double objective. On one hand, it proposes the first French translation of all epigrams and hymns composed by the author for the ambrosian Church during his diaconate at Mailand. There was indeed until here only a partial translation in Italian, based on the Latin text edited by F. Vogel at the end of XIXth century. However, this edition does not take into account the manuscripts with all the opera of the author discovered recently, neither the numerous isolated liturgical books (never listed nor studied up to there) in which we find three of his hymns : most of them have been copied between the XIth and the XVth century in south Italy. On the other hand, it proceeds to an exhaustive thematic and aesthetic study of its religious carmina, usually assimilated to his worldly poems, and like the latter depreciated because of their affected writing considered vain and source of darkness. Such a comparison is nevertheless reducing, because these tituli and hymni, linked of two different manners to the Milanese spiritual life, testify a real commitment of Ennodius for his Church: hidden behind the bishop in place, whose he was the spokesman, he made himself the official bard of the milanese Church which, thanks to the new area of peace, wanted then to take up with her illustrious ambrosian past

Testo completoAbstract (sommario):
Le succès éditorial et critique de l'Oraison sur l'origine et l'office de la littérature (1809) de Foscolo a laissé dans l'ombre les autres textes du corpus des cours que l'écrivain italien assura à l'Université de Pavie. Ce travail souhaite éclairer cet aspect de l'œuvre de Foscolo, souvent négligé par la critique littéraire. A cette fin nous reconstruisons l'activité d'enseignement de Foscolo à Pavie et la place qu'elle assume dans sa réflexion littéraire et philosophique. Les cours concentrent à eux tous seuls bon nombre de motifs-clé de sa production littéraire. Ils catalysent les suggestions provenant de ses lectures et des débats littéraires des années précédentes qui avaient nourri une réflexion restée jusque-là à l'état fragmentaire tout en préparant la systématisation de sa pensée critique qui caractérise la production de sa période anglaise (1817-1827). En particulier, dans ces cours, Foscolo poursuit deux objectifs principaux : 1) définir la fonction civique de l'homme de lettres à travers une nouvelle caractérisation éthique et politique de l'éloquence ; 2) formuler un projet éducatif qui s'adresse à la classe moyenne, d'où émerge la nécessité de créer une langue unitaire et une tradition littéraire nationale et la revendication d'un nouveau modèle d'historiographie qui dépasse les limites de l'érudition du XVIIIe siècle. Cette étude est complétée par la reconstruction de l'histoire éditoriale des cours et leur commentaire. Le texte revu et corrigé critiquement (par rapport à la dernière édition, celle d'Emilio Santini, qui ne rend pas compte d'importantes corrections et variantes) sert de base pour le commentaire, une annotation critique et historique qui illustre les sources utilisées par Foscolo et de usage, direct ou indirect, qu'il en fit dans sa réflexion littéraire, philosophique et linguistiqueThe positive reviews – both editorial and critical – achieved by Foscolo's 1809 lecture On the origin and duty of literature have overshadowed the Italian author's text corpus of the classes he's given at the University of Pavia. This study is willing to explain this specific aspect of Foscolo's work, often skipped by literary criticism. For this aim we reenact Foscolo's teaching experience in Pavia and the importance of it in His philosophical and literary thought. His classes alone include a good number of key themes of His literary work. Those catalyze the suggestions coming from his readings and the literary debates of the previous years, that have fed His thinking, at that time still in development , but soon to be settled in His critical thought, clearly visible in His English period work (1817-1827). In these classes particularly, Foscolo tries to reach two primary goals: 1) to define the civil duties of a literary man by a new ethical and political definition of oratory; 2) to create an educational project for the middle class; hence it bursts the need for creating a common unitary language and a national literary tradition as well as the assert of a new historiographical model, able to go beyond the Eighteenth Century scholarship boundaries. This study is concluded with a timeline reconstruction of the publishing history of His classes and their commentary. Such text lessons, critically revised and corrected (compared to their last edition available – edited by Emilio Santini – that failed to consider important revisions and different versions) are the foundation of the commentary, a critical and historical marginalia showing the sources used by Foscolo and of the use – either directly or indirectly – he made in His literary, philosophical and linguistic thought

Testo completoAbstract (sommario):
A utilização de resíduos tem se mostrado como uma boa alternativa na redução do impacto causado pelo consumo desordenado de matéria-prima e pela redução das áreas de disposição, em virtude do grande volume de resíduos descartados a cada ano em todo mundo. Neste contexto se inserem os resíduos de pneus provenientes da recauchutagem. Este trabalho foi desenvolvido com o objetivo de estudar algumas propriedades de pavers de concreto, com substituição parcial do agregado por resíduos de pneus. Para a produção dos pavers foram consideradas as faixas de consumo de cimento Portland de 292,84 kg/m³, 323,06 kg/m³ e 347,00 kg/m³, e os níveis de incorporação dos resíduos estudados foram de 8%, 10%, 12%, 15% e 20%, em volume. As propriedades foram: resistência à compressão, absorção de água, resistência ao impacto, resistência à abrasão profunda e expansão por umidade. Os resultados mostram que ocorre queda na resistência à compressão. Na absorção de água, não podemos afirmar que essa propriedade é afetada de maneira negativa. Os pavers demonstraram grande capacidade de absorção de energia (tenacidade). Os resultados de resistência à abrasão mostram-se interessantes para a aplicação em ambientes com baixas solicitações. A expansão por umidade não afetará o intertravamento dos pavers. Dessa forma, os resultados mostraram viabilidade na utilização dos pavers com resíduos de pneus em pavimentação intertravada com solicitações leves.Concerns regarding the environment and shortage of natural resources have led the way for sustainable alternatives. The recycling process seems to be a suitable alternative to minimize the use of natural resources as well as the lack of proper disposal sites caused by the large amounts of discarded waste worldwide. Within this context, rubber residues from recapped tires are used for insertion. This work was developed with the objective of studying some of the properties of concrete paving, with partial substitution of the aggregate for tire residues. For the production of pavers the bands of Portland cement consumption was considered at 292,84 kg/m³, 323,06 kg/m³ and 347,00 kg/m³, and the levels of residues incorporation at 8%, 10%, 12%, 15% and 20%, in volume. The studied properties were: compressive strength, water absorption, impact resistance, deep abrasion and expansion resistance to humidity. The results show decrease in the compressive strength. The water absorption does not undergo negative influence. Pavers demonstrated substantial capacity for energy absorption (tenacity). The results of abrasion resistance reveal interesting applications for locales with low degree of demands. Expansion by humidity will not affect the interspersing of pavers. However, the results have shown viability in the use of pavers interspersed with tire residues in asphalt with light load demands.

The present research proposes a technical evaluation for the use of the waste generated in the Water Treatment Plant, Eng. Rodolfo José Costa e Silva, located in the city of Goiânia, State of Goiás, Brazil, as a partial substitute for the fine aggregates of cementitious elements. The study conducted the analysis of the residues, from the material science point of view, through the physical and mineralogical characterization, as well as the investigation concerning the possibility of pozzolanic activity of the material. Therefore, the parameters found were compared based on specific literature and current normalizations, and the study evaluated the similarity between the residue characteristics and the traditional raw materials used in the production of cementitious materials, such as sand, clay, and limestone; in this context, an experiment was carried out with the application of WTP residues in a component used in construction: concrete floor (Paver). The results of the mechanical tests were statistically analyzed to see the influence of the residue, age and interaction between these variables in the results. It was found that the proportion of 5% of residue significantly improved the mechanical resistance of Pavers (33.5%) at 28 days in the control sample, but water absorption increased (68.8%). In this way, a sustainable alternative of insertion of the waste in the productive chain of the construction was sought, producing a cement element, and at the same time contributing to reduce the environmental impact caused by the release of the residues in the springs. Aiming at reducing the environmental liabilities of the water industry, as well as reducing the extraction of raw material for cement production.
A presente pesquisa propõe uma avaliação técnica para utilização dos resíduos gerados na Estação de Tratamento de Água Eng°. Rodolfo José Costa e Silva, que utiliza o sulfato de alumínio no tratamento e está localizada em Goiânia-Goiás, como substituto parcial dos agregados miúdos em componente cimentício - Paver. A pesquisa analisou a incorporação de resíduos, sob o ponto de vista da ciência dos materiais, por meio da caracterização física, química e mineralógica, bem como, com uma investigação referente à possibilidade de atividade pozolânica do material. Dessa maneira, os parâmetros encontrados nos ensaios, foram comparados às bases da literatura específica e normas vigentes, levantadas na revisão bibliográfica, e posteriormente o estudo avaliou a similaridade das características do resíduo com as matérias primas tradicionais utilizadas para produção de materiais cimentícios, como: areia, argila e pedra calcária, dentre outras; nesse sentido, foi elaborado um experimento com aplicação de resíduos de ETA em componente utilizado na construção civil: o piso de concreto Paver. Os resultados dos ensaios mecânicos foram analisados estatisticamente para perceber-se o grau de influência do teor de resíduo, idade e interação entre essas variáveis nos resultados. Constatou-se que a proporção de 5% de resíduo melhora significativamente a resistência mecânica dos Pavers (33,5%) aos 28 dias, em relação a amostra de controle, porém a absorção de água aumentou (68,8%). Assim, encontrou-se uma alternativa sustentável de inserção do resíduo na cadeia produtiva da construção, produzindo um elemento cimentício, e ao mesmo tempo contribuindo para reduzir o impacto ambiental causado pelo lançamento dos resíduos nos mananciais. Objetivando a redução do passivo ambiental da indústria da água, bem como a diminuição da extração de matéria prima para produção dos elementos cimentícios.
