Brick manufacturing requires a considerable amount of energy and land, but these numbers have been difficult to quantify in rural parts of the developing world. The environmental impact of unfired bricks in India is investigated through modeling the effects of materials composition and processing on energy consumption, carbon dioxide equivalent emissions, and land surface area use. The analysis uses a cradle-to-gate life cycle assessment to quantitatively estimate these impacts. The depth of soil extraction has a significantly affects the land use required for bricks; changing this depth in practice or through regulation has the potential to reduce environmental impact without affecting brick performance. The impact of unfired bricks depends greatly on composition, in particular the amount and type of stabilizer and the incorporation of fly ash. While stabilizers increase the environmental burden, the performance gain is potentially worth these effects when compared to energy intensive fired bricks. Future work could expand the model to quantify the relevant cost and performance tradeoffs with environmental impact.

The current and projected growth of India's economy and population will continue to lead to increased demand for buildings and infrastructure, and there is a real need to consider what this increase means in terms of natural resource depletion, air pollution, contributions to global warming through greenhouse gas emissions during production and transport, and energy demands to be placed on an already strained energy network. Fired-clay bricks are the most commonly used building material in India, but recently, masonry units that don't require firing (stabilized bricks) have penetrated the market. There has been an exploration of the amalgamation of traditional earthen building materials combined with chemical binders. While these masonry materials are often considered superior in terms of environmental impact due to their lack of firing in visceral, black smoke-producing kilns, as well as their typically local (even on-site) production, there has been limited research into their actual environmental footprint. This thesis establishes models for robust analysis, and analyzes the environmental and cost tradeoffs associated with various building materials' choices to evaluate the hypothesis that the optimal materials choice is heavily dependent on the local soil composition and industrial ecosystem. That is, there is likely not one answer to the question of which is better: traditional fired clay bricks (red bricks) or alternative, cementitious materials, and instead, decision making must be assisted by analysis of the overall environmental impact of the upstream production and transportation of each material. Because of the variety of conditions throughout India, there is a need for this sort of tool to perform these analyses to determine the conditions under which different building materials have better environmental and/or economic outcomes. The analyses performed in this thesis conclude that there is the potential for alternative materials to break into the market, particularly in areas where red bricks are not produced on an industrial scale.

O aspecto teÃrico à o momento em que os conteÃdos sÃo discutidos de maneira explicativa; jà na prÃtica, tais conteÃdos sÃo desenvolvidos experimentalmente. Considerando este fato e as pesquisas realizadas para a confecÃÃo deste trabalho em uma escola indÃgena, notou-se que os conteÃdos da disciplina de QuÃmica desta escola estavam sendo ministrados apenas teoricamente, sem a realizaÃÃo de aulas prÃticas. Por essa razÃo, atualmente, os alunos pertencentes ao Ensino MÃdio da Escola Diferenciada de Ensino Fundamental e MÃdio Ãndios Tapebas se sentiam insatisfeitos por nÃo serem contemplados com aulas prÃticas. Sobre um estudo feito na referida escola, foi realizada uma pesquisa de campo na qual foram verificadas, por meio de questionÃrios, as principais insatisfaÃÃes dos alunos. Uma delas à a falta de um LaboratÃrio de CiÃncias ou de QuÃmica para a Escola IndÃgena. Portanto, verificou-se que tanto os professores como os alunos dos 1Â, 2 e 3 anos do Ensino MÃdio desta escola necessitavam de aulas prÃticas, mesmo que estas fossem improvisadas em sala. Foi entÃo que surgiu a ideia de se construir um Manual de prÃticas elaboradas a partir dos conteÃdos de QuÃmica do ensino mÃdio. Esse Manual foi construÃdo atravÃs da descriÃÃo de atividades realizadas com diversos materiais utilizados no cotidiano dos alunos da Escola IndÃgena. Para essas prÃticas experimentais foram utilizados alguns materiais naturais e artificiais, e a maior parte deles estava disponÃvel na escola pesquisada. Esse manual à composto de 15 prÃticas, e tem o objetivo de contribuir para melhorar a qualidade do ensino e da aprendizagem nas aulas teÃricas de QuÃmica, atravÃs de sua complementaÃÃo por meio de aulas prÃticas adequadas e destinadas Ãs escolas que nÃo possuem laboratÃrio.

Impedance-based Non-Destructive Evaluation for Additive Manufacturing (INDEAM) is a quality control approach for detecting defects in structures. As indicated by the name, impedance-based evaluation is discussed in this work in the context of qualifying additively manufactured (3D printed) structures. INDEAM fills a niche in the wider world of nondestructive evaluation techniques by providing a less expensive means to qualify structures with complex geometry. Complex geometry complicates inspection by preventing direct, physical access to all the surfaces of a part. Inspection approaches for parts with complex geometry suffuse a structure with energy and measure how the energy propagates through the structure. A prominent technique in this space is CT scanning, which measures how a structure attentuates x-rays passing through it. INDEAM uses piezoelectric materials to both vibrate a structure and measure its response, not unlike listening for the dull tone of a cracked bell. By applying voltage across a piezoelectric patch glued to a structure, the piezoelectric deforms itself and the bonded structure. By monitoring the electrical current needed to produce that voltage, the ratio of applied voltage to current draw---impedance---can be calculated, which can be thought of as a measure of how a system stores and dissipates energy. When the applied voltage oscillates near a resonant frequency of a structure (the pitch of a rung bell, for example) the structure vibrates much more intensely, and that additional movement dissipates more energy due to viscosity, friction, and transmitting sound into the air. This phenomenon is reflected in the measured impedance, so by calculating the impedance value over a large range of frequencies, it is possible to identify many resonances of the structure. So, the impedance value is tied to the vibrational properties of the structure, and the vibration of the structure is tied to its geometry and material properties. One application of this relationship is called impedance-based structural health monitoring: taking measurements of a structure when it is first built as a reference, then measuring it again later to watch for changes that indicate emerging damage. In this work, the reference measurement is established by measuring a group of control structures that are known to be free of defects. Then, every time a new part is fabricated, its impedance measurements will be compared to the reference. If it matches closely enough, it is assumed good. In both cases, impedance values don't indicate what the change is, just that there was a change. A large portion of this work is devoted to determining the types and sizes of defects that can be reliably detected through INDEAM, what effect the part material plays, and how and where the piezoelectric should be mounted to the part. The remainder of this work discusses new methods for conducting impedance-based evaluation. In particular, overcoming the extra uncertainty introduced by moving from part-to-itself structural health monitoring comparisons to the part-to-part quality control comparisons discussed in this work. A new method for mathematically comparing impedance values is introduced which involves extracting the resonant properties of the structure rather than using statistical tools on the raw impedance values. Additionally, a new method for assessing the influence of piezoelectric mounting conditions on the measured impedance values is demonstrated.

Full textDuring the XIXth century, the beggining of industrialisation of perfumery in the world. Specifically inFrance and in Grasse. Resulted in an augmentation in raw materials in spite of the invention and theincrease of the synthetic molecules in the perfume and aromatic composition. In order to supply itselfin raw materials, many French and Grasse society organise trade relations with foreign countries, likeItaly and Bulgaria. In the same time, the increasing establishment of the perfumers in Africa, Asia,America and Oceania, corresponds in diversified strategies according to the mobilized colonies : inthe Maghreb, they extend the culture of mediterranean raw materials ; in Indo-China and Guyana,they are supplied out of specific raw materials like the star anise or the rose wood ; while Africa andOceania, they serve as a laboratory for multiple acclimatizations of mediterranean raw material andalso tropical species, like vanilla or ylang-ylang. Among these « colonial laboratories », the islandsof the Indian Ocean, for which ylang-ylang, geranium, clove or vanilla, were, until the XIXth century,completely unknown. They became one of the principal world production centers of raw materialsunder the influence of the French and Grasse perfumers. The objective of this thesis is to considerthis singular trajectory, since the rise of the first factories in France until the creation of a worldnetwork of supply. It also questions the links and the relations between the various producing zonesand the Grasse perfumery

Full textBrief of Conclusion : Environmental pollution due to anthropogenic sources of vehicular exhausts and industrial emissions is rapidly becoming a critical issue of public concern worldwide. Industrialization, urbanization, population growth and associated increase in energy demands have resulted in a profound deterioration of environmental quality in urban India. Specifically, burning of fossil fuels in industries and transport sector has led to increase in concentrations of particulate pollutants in the environment leading to pollution, which can threaten the health of human beings and affect the quality of environment. The increasing pollution level day-by-day has prompted policy makers, scientists, environmental organizations to opt for fast, cost effective, complimentary yet reliable tools against the existing traditional time consuming, cost intensive and destructive tools for quick information. Environmental magnetism is one such tool which has been widely used to investigate the degree, source, scope and spatio-temporal evolution of anthropogenic pollution related to industrial and other human activities in this thesis. The determination of different magnetic mineral sources, called magnetic components, is an important task in environmental magnetism. The premise is based on that human activities constitute an additional source of magnetic components, which can be utilized for pollution monitoring. Technical challenges in recognition of anthropogenically produced magnetic particles in high magnetic background values from Deccan Trap basalts pose difficulties in order to define accurately a standard magnetic reference level. For the first time, two case studies of a successful pollution screening from Deccan Trap basalts employing integrated environmental magnetic, geochemical and microscopic investigations were carried out. Further, in situ susceptibility survey and laboratory measurements of a suite of rock magnetic parameters were carried out for obtaining information on spatial magnetic dust/soil, carrying a load of environmentally relevant heavy metals. Mineral magnetic measurements as a tool for mapping heavy metal contamination of road dusts and topsoils around a power plant were reported here. As aforementioned, virtually all types of magnetic matter generated by anthropogenic mechanisms outlined were within coarser particle range from 0.2 m up to tens of m. Thus for representative particulate nature of the road dusts and contaminated topsoils and for minimization of natural magnetic contamination of the basaltic environment, the dust samples <44 µm and topsoil samples <63 µm fraction were analyzed in detail. This fractionation process ensured removal of coarse grains of basaltic material and contained a large component of the anthropogenic dust particulates of airborne origin. We briefly summarize the results and provide a brief of the future scope of the present thesis work.

Full textThe synthesis and characterization of aromatic substituted titanium oxo-entities as well as their utilization in hybrid materials is presented. Two main routes have been chosen for the synthesis, in respect to the structure and morphology of the obtained entities: - The first one is the reaction of titanium alkoxide with a slightly excess of carboxylic acid, which yields in well-defined titanium oxo-alkoxo clusters of formula Ti6O4(C6H5COO)8(OR)8 (with R = Et, Prn or Bun) or TixOy(CH2=CH-C6H4COO)z(OPri)z. - The second route is the reaction carried out with a large excess of carboxylic acid to remove all isopropoxide groups. Therefore well-defined oxo-carboxo cluster of formula Ti8O8(C6H5COO)16. (C6H5COOH)2. H2O, or titanium oxo-entities functionalized with amino, nitro and hydroxy groups could be obtained. Afterward the use of the former synthesized products in organic and/or inorganic-organic hybrid materials, particularly for modification of thermal and optical properties, is outlined

Full textFor our study, we visited a Government Lower Primary School in India to inquiry about how a school in another schooling context teaches mathematics. Our research questions were: How does an Indian Government Lower Primary School work with mathematics? What are the teachers' perceptions of the school’s teaching approach? In addition to these questions and to inquire deeper into this subject, we also investigated How do the teachers’ perceptions and method of teaching connect to Yackel and Cobb’s framework of the different kinds of norms operating in the classroom?We did a qualitative study, staying at the school for three weeks to interview teachers about their method of teaching mathematics as well as observing how they were teaching mathematics and the norms that operated in the classroom. We also gathered information about their mathematics laboratory. During our interviews and observations we came to the conclusion that the school worked with activity-based learning by using manipulative materials. All teachers as well as the principal cooperatively strived to meet the curricula objectives, with the same teaching approach. We also found that the teachers’ values and beliefs about how mathematics should be taught, affect the norms operating in the classroom.This study cannot be generalised for all schools in India or even in this area. This study is a minor study which only considered one particular school which used an interesting teaching method, activity-based learning with manipulatives.

Full textThe Sierra Nevada of Santa Marta (Colombia) has been a threatened land by the armed conflict, development projects, hydrocarbon exploitation, mining, drug traffic and tourism. In this context, the survival of indigenous peoples and their main resource the water are at risk. To face this, the indigenous communication groups of the Wiwa, Arhuaco (Iku), and Kogi villages have used audiovisual productions, since 2002, as a symbolic and political tool, to defend their territory, showing their realities and narrate themselves. Indigenous representation and self-representation from the cinema, photography and media of communication has taken two main theoretical approaches. On the one hand, it implies, how indigenous has been represented by the Church, the State, multinationals, anthropology, film documentaries and tourism, in contexts of evangelization, colonialism, exploitation and the extractive economy. On the other hand, indigenous self-representation has implied the appearance of what some scholar has called: symbolic resistance, cultural activism and visual sovereignty. This research proposes an ethnography of images as a theoretical and methodological approach. It focuses on the use of production, circulation and significance of images of the Iku community (arhuaco). I argue that the production of photosynthetic images from indigenous has socio-political and cultural implications. From a socio-political approach, I said that the indigenous communications of the Sierra Nevada are configuring new ways to understand ethnicity in contemporary Colombia. These transformations are linked to social practices of image production, in the context of multiculturalism and cosmopolitanism, which has allowed the indigenous to expand their space political experience. From a cultural perspective, photosynthetic images allow us to approach "ways of seeing", which refer to the temporal variables of sensitivity and perception. Ethnographic work was developed through the elicitation of image, in different multi-site contexts within the Sierra Nevada de Santa Marta and outside it. At the same time, an accompaniment was made to the Arhuaco Communications Collective Yosokwi and his director Amado Villafaña in the viewing and production of audiovisuals. As a result of this collaboration, we made the film Wàsi (to see).

Full textHistorically, light was a centre of interest for numerous inquisitive people: the philosophers who were interested in its nature and the scientists who wanted to interpret its associated phenomena. Optics is playing a pivotal role in many of our day to day applications.The refractive index is one of the most significant parameters in photonics. An increase in the efficiency of the photonic devices, like Light Emitting Diodes, Solar Cells, etc., can be achieved by reducing the refractive index mismatch of materials used in the optical devices.This thesis throws some light into the tailoring the refractive index of materials, by giving detailed aspects of refractive index and engineering of the refractive index using polymer nanocomposite. This introductory chapter evolves into a wider discussion on the refractive index and the types of refractive index and the potential leverage that can be obtained by engineering the refractive index. Polymer thin films were prepared and the nanoparticles were introduced so as to modify the refractive index. Similarly, thick polymer films were prepared using PMMA and Polystyrene and these were utilized to optically and morphologically characterize the prepared samples. Multiple methods have been utilized to prepare the polymer films. Ultra thin polymer films were also prepared using the spin coating technique and later the thickness of the polystyrene film was changed so as to understand its impact on the refractive index. There were multiple challenges to overcome while carrying out the research like the preparation of ultra pure substrate, uniformity in the prepared polymer thin film, adherence of the polymer thin film on to the substrates after solvent casting etc. All the challenges were overcome using the innovations, which are detailed in the thesis

Full textAn experimental programme has been performed on three types of bituminous mixes with variable recycling rates and the possible addition of rejuvenator. The mix composition and the production process have been defined in order to perform a comparative analysis. The coating process modifies the physico-chemical parameters of the binders, like consistency, glassy transition temperature, cristallizable moiety, aromatics and asphaltenes rates; the above variations are limited by using the rejuvenator. As the RAP content increases, the compactibility and the rutting of the mixes decrease and the viscoelastic stiffness increases, but the rejuvenation reduces these variations. Globally, RAP increases the fatigue resistance of the mixes and flattens the Wöhler curve. Rejuvenation enhances ɛ6 fatigue parameter; fatigue performances increase with R&B temperature and colloidal index of the binder and as the viscous component of the mixes decreases. The positive impact of a high rate of RAP and of the rejuvenation on the allowable traffic has been evaluated from the structural design of a threelayered pavement. At low temperature, the deterioration of the tension ductility and of the stress restrained failure temperature produced by the RAP, is limited by the rejuvenation; a compromise with the fatigue resistance has to be found. The rejuvenated mixes laid as surface layers on a provincial road have experienced a smaller evolution that non rejuvenated mixes

Full text- Utiliser des multitraitements de surface peut se faire en scindant les différentes requêtes en sous-ensembles, de manière à ce que chaque traitement réponde à l’un d’eux. Dans quel ordre ces requêtes doivent-elles être introduites par rapport au substrat ?
- Comment sélectionner les traitements de surface répondant à chaque requête individuelle ?
- Comment classer des multitraitements en termes d’adéquation au problème posé ?
Dans ce travail, les première et troisième questions sont abordées, en explorant les requêtes concernant habituellement les dispositifs de moulage de l’aluminium :
- Résistance aux contraintes d’origine thermique.
- Résistance à la corrosion par les métaux fondus.
- Résistance au frottement.
L’analyse de la bibliographie relative aux traitements de surface utilisés dans ces systèmes a été analysée et des « architectures »-types ont été identifiées (chapitre 3). On prévoit, par exemple, un traitement conférant la résistance à la fatigue superficielle, ainsi qu’un revêtement étanche et résistant à l’aluminium fondu. Une barrière thermique est parfois préconisée.
Pour chacune des architectures, des traitements de surface individuels peuvent être sélectionnés. Un « facteur de performance » permettant de classer les solutions par rapport au problème de la fatigue thermique a été construit (chapitre 4) et discuté dans deux situations :
- Lorsqu’un revêtement est présent, et que les contraintes d’origine thermique (différence de dilatation thermique couche-substrat) menacent de le rompre lors de l’immersion dans un milieu corrosif à haute température. Des essais de corrosion dans de l’aluminium fondu ont été réalisés sur un acier revêtu par du nitrure de chrome dopé à l’aluminium, synthétisé par déposition physique en phase vapeur (chapitre 5 – collaboration :Inasmet).
- Lorsque des variations thermiques rapides menacent de rompre le substrat et la (les) couches. Des essais de fatigue thermique ont été réalisés sur de l’acier à outils pour travail à chaud non traité, boruré ou recouvert d’un multitraitements (zircone yttriée / NiCrAlY / boruration / acier). Le revêtement en zircone yttriée a été obtenu par projection par plasma. L’essai de fatigue thermique a été modélisé et le facteur de performance, discuté (chapitre 6).
Au chapitre 7, les architectures-types ont été introduites dans une méthodologie de sélection des multi-traitements de surface, qui a été appliquée dans deux cas :
- Celui des moules de fonderie, devant résister à la fatigue thermique et à la corrosion par l’aluminium fondu. Le facteur de performance a été extrapolé à d’autres situations qu’aux chapitres 5 et 6. Les solutions habituellement proposées pour résoudre ce problème sont retrouvées.
- Celui de deux pièces en acier frottant l’une contre l’autre en présence d’aluminium fondu.
To select surface treatments, one must account for the required functional properties, the substrate features and the solicitations the substrate must endure. Certain combinations of these parameters make it difficult to select a single surface treatment, a reason why several successive treatments are preferred. To select them, one needs to determine:
- How to divide the several requests into groups and how to stack up these groups from the substrate to the outer surface, so that each treatment deals with one specific group of requests/properties.
- How to select individual layers for each group of properties.
- How to rank the multi-treatments in terms of relevance for a given application.
In this work, one tries to answer the first and the third questions, by studying the case of aluminium foundry, in which the industrial devices frequently face the following solicitations:
- Thermal stress (thermal fatigue, thermal expansion mismatch).
- Presence of corrosive molten metal.
- Sliding wear.
In the literature, several “standard” architectures are proposed (chapter 3), like a diffusion layer reducing superficial fatigue plus a corrosion barrier layer. A thermal barrier coating is also sometimes proposed.
For each of these architectures, one can select individual treatments. To rank them, one devised a “performance index” for thermal stress (chap.4), which is discussed for two cases:
- For large differences between layer and substrate thermal expansion coefficients, when both are put into contact with a high temperature corrosive medium, the layer may be damaged. One discusses this case by examining the corrosion caused by molten aluminium for a steel substrate coated by anticorrosive chromium nitride doped with aluminium. The layer is produced by physical vapour deposition (chap. 5 – cooperation: Inasmet).
- Repeated fast surface temperature transients can also damage the substrate and/or the layer by thermal fatigue. One conducted thermal fatigue tests with samples of hot work tool steel, respectively untreated, simply borided and protected by a multilayer. In the last case, top coat is yttria stabilised zirconia, followed by a nickel superalloy and then a borided layer (undercoat). One synthesized the zirconia coating by plasma spray and one modelled the thermal fatigue (chap. 6).
In chap. 7, architectures from chap. 2 are introduced in a multi-treatment selection routine, which is applied in two cases:
- Foundry moulds for molten aluminium, withstanding both thermal fatigue and corrosion. The devised performance index is extrapolated beyond the tests of chap. 5 and 6 to treatments for this industrial application, thereby quantifying their respective merits.
- A foundry device exposed to molten metal and sliding wear.
