    El campo Humapa, es un campo petrolero ubicado en la región central del paleocanal de Chicontepec el cual ha sido afectado su desarrollo por el demandante y acelerado ritmo de desarrollo de la industria energética en México. Ejemplo de este es el no contar con un modelo petrofísico sustentado en análisis de núcleos, que permita reducir el umbral interpretativo asociado a las evaluaciones petrofísicas. Esta tesis de maestría centra su atención en la generación de un modelo petrofísico afianzado en los resultados obtenidos en los núcleos tomados en los diferentes pozos en la región sur del campo Humapa y en los registros geofísicos en esta misma área, para con esto reducir la incertidumbre y poder generar un modelo geoestadistico que permita ser predictivo con las propiedades petrofísicas que se encuentran en las localizaciones que aún no han sido perforadas y con esto poder dirigir de manera eficiente el desarrollo de la explotación del campo Humapa. ABSTRACT The Humapa field is an oil field placed in the central region of the Chicontepec reservoir, the development of this field has been affected by the accelerated development rhythm of the energy industry in Mexico. Example of this is has not have a petrophysical model based in core analysis that enables to reduce the interpretative spectrum associated with the petrophysical evaluations. This master thesis focus its attention in the generation of a petrophysical model, based on the results of the different core analysis and petrophysical logs taken in the oil wells in the southern region of the Humapa field, in order to be able to reduce the uncertainty and create a geostatistical model that allow us to predict petrophysical properties in oil wells that has not been drilled yet, and with this be able to lead efficiently the development of the exploitation of the Humapa fiel

    Processing and characterisation of Calcium SulfoAluminate (CSA) eco-cements coated with a hybrid organo-inorganic material for photocatalytic applications

    Get PDF
    On the one hand, Calcium SulfoAluminate (CSA) eco-cements are receiving increasing attention since their manufacture produces up to 40% less CO2 than ordinary Portland cement (OPC). In addition, they show interesting properties such as high early-age strengths, short setting times, impermeability, sulfate and chloride corrosion resistance and low alkalinity. On the other hand, water treatment is a key issue and it will become much more important in the decades ahead. We have developed a photocatalytic material capable to degrade contaminants in water, under both UVA and visible radiations. In both cases, it works more effectively than nano-TiO2 (Evonik P25). The environmental benefits of the use of CSA eco-cements with a photocatalyst are two folds: the photocatalytic treatment of contaminated water, and lower CO2 emissions because of the use of eco-cements rather than OPC. However, before preparing the coating, different parameters need to be under control. This includes the effect of the photocatalyst onto the eco-cement (setting time, phase assemblage, and so on), and the effect of the eco-cement on the photocatalyst. This work deals with the processing and characterisation of coatings onto CSA eco-cement pastes, including rheological behaviour, setting time, adhesion, and so on.Universidad de Málaga.

    A presente tese de doutoramento tem como objetivo compreender e aprofundar os conhecimentos sobre a relevância da dança popular no processo de formação do bailarino clássico e contemporâneo na ETBB. Buscando uma comunicação interpessoal para se chegar a esta compreensão a partir dos significados das experiências vividas pelos participantes do estudo, utilizou-se a entrevista semiestruturada e foram observadas aulas de danças populares e contemporânea. O Projeto Político e Pedagógico e fontes primárias e secundárias da ETBB também foram utilizados para consultas. Os participantes do estudo eram os alunos concluintes de dança clássica (N=3), de dança contemporânea (N=3), professores (N=4), bailarinos da Companhia Jovem da ETBB (N=4), diretor e coordenadora (N=2). As análises foram desenvolvidas dentro da perspectiva fenomenológica, com abordagem qualitativa, a partir de uma triangulação realizada com os dados obtidos onde surgiram categorias (ensino, filosofia, currículo, metodologia, disciplinas essenciais, disciplinas complementares, bailarino, técnica, relação pessoal, motivação) que formaram nosso eixo de análises. Verificou-se que a ETBB possui uma estrutura de ensino da dança reconhecida oficialmente pelo sistema estadual da educação do estado de Santa Catarina no Brasil, pelo Ministério da Educação e pela Escola Coreográfica de Moscou. O currículo foi desenhado dentro de uma perspectiva tradicional, composto por diferentes componentes curriculares, divididos em essenciais e complementares, na qual nesse último a dança popular se encontra. O professor é reconhecido como figura central no processo de ensino; aos alunos cabe o comprometimento com as aulas e com o seu desenvolvimento técnico. Os alunos, após passarem os quatro primeiros anos de formação na escola, e que não atingem os objetivos como o corpo ideal e as competências exigidas, tem que deixar a ETBB. Depois de graduarem-se, mesmo encarando a escassez de oportunidades de emprego na área, os alunos têm conseguido encontrar trabalho em diferentes funções da dança e em diferentes países. A dança popular ocupa um pequeno espaço em número de aulas na matriz curricular, porém ocupa bom espaço nos espetáculos realizados pela escola, juntamente com a dança clássica e contemporânea. Ficou evidente que os alunos sentem-se felizes nessas aulas, e que os professores concordam entre si sobre os benefícios destas aulas para seus alunos, tanto nos aspectos motores, afetivos, sociais quanto no artístico. Devido ao número restrito de aulas semanalmente, estas são focadas no ensaio do repertório coreográfico da escola para as apresentações. Após as análises realizadas, apresentamos uma proposta metodológica para o ensino da dança popular que se chama “Dança popular, espaço coletivo de saberes”. Entendemos que esta metodologia para o ensino da dança popular pode oportunizar aos professores o uso de novas estratégias pedagógicas favorecendo o reconhecimento da cultura brasileira, de novos processos criativos, em dar “voz” aos alunos, aumentando a autonomia nas decisões tomadas, formação cidadã. Esta reflexão realizada em torno das estruturas do vivido na ETBB fez surgir a proposta que foi baseada em princípios da arte e educação, gerando novas possibilidades de trabalhar o corpo sob a perspectiva de dança popular de matriz tradicional.The present thesis aims to understand and deepen the knowledge about the relevance of popular dance in the process of training the classical and contemporary dancer at the Bolshoi Theater School in Brazil (ETBB). Is seeks an interpersonal communication to arrive at this understanding from the meanings of the experiences lived by the participants of the study, and for that, the semi structured interview was used during the conversation with the participants and classes of popular and contemporary dances were observed. The Political and Pedagogical Project of the ETBB and primary and secondary sources of this school were also used for consultation. The participants of the study were the graduating students of classical dance (N=3), contemporary dance (N=3), teachers (N=4), dancers of the Companhia Jovem da ETBB (N=4), director and coordinator (N=2). The analyzes were developed from the phenomenological perspective, with a qualitative approach, based on a triangulation performed with the data obtained where categories emerged (teaching, philosophy, curriculum, methodology, essential disciplines, complementary disciplines, dancer, technique, personal relation, motivation) which formed our analysis axis. It was verified that the ETBB has a dance teaching structure officially recognized by the state education system of Santa Catarina, the Ministry of Education from Brazil and the Moscow Choreographic School. The curriculum was designed from a traditional perspective, composed of different curricular components, divided into essential and complementary components, and in this last one the popular dance is found. The teacher is recognized as a central figure in the teaching process; the students are committed to the lessons and their technical development. Students who do not achieve goals such as the ideal body and the required skills after having passed the first four years of schooling, must leave the ETBB. After graduating, even facing the scarcity of employment opportunities in the area, students have been able to find work in different roles of dance and in different countries. The popular dance occupies a small space in number of classes in the curricular matrix of the ETBB, but occupies good space in the spectacles realized by the school, along with the classic and contemporary dance. It became clear that students feel happy in these classes, and that teachers agree among themselves on the benefits of these classes for their students, both in the motor, affective, social and artistic aspects. Due to the limited number of lessons per week, these classes are focused on the choreographic repertoire of the school for presentations. After the analyzes done, we presented a methodological proposal for the teaching of popular dance that is called "Dança popular: espaço coletivo de saberes". We understand that this methodology for teaching popular dance can provide teachers with the use of new pedagogical strategies favoring the recognition of Brazilian culture, new creative processes, giving "voice" to students, increasing autonomy in decisions taken, formation for citizenship. This reflection carried out around the structures of the lived in the ETBB gave rise to the proposal based on principles of art and education, generating new possibilities of working the body under the popular dance related to tradition
