A experiência de Fauzi - dramaturgia em processo / -

Pinto, Pedro Vicente de Azevedo Alves 30 November 2018 (has links)
Investigação sobre a noção de \"alquimia do teatro\" a partir da leitura do livro autobiográfico Mare Nostrum - sonhos, viagens e outros caminhos, de Fauzi Arap, realizada como estudo para a criação de uma dramaturgia baseada no depoimento. À partir da narrativa, que contempla o envolvimento do artista numa psicoterapia experimental baseada no uso psiquiátrico do LSD, identifica-se um paralelo entre a trajetória do autor e a dinâmica do mito associado à arte teatral - o mito grego Dioniso - e se reflete sobre as circunstâncias em que se deu a criação de sua obra, com foco no período da contracultura histórica brasileira. Buscando delinear a noção sugerida no capítulo 20 do livro \"o teatro da alquimia e a alquimia do teatro\", discute-se a questão do \"teatro ritual\" e se resgata a qualidade alquímica do mito de Dioniso, esboçando-se a noção de uma \"alquimia dionisíaca\". / Research on the notion of \"theater alchemy\" from reading the autobiographical book Mare Nostrum - dreams, travels and other ways, by Fauzi Arap, carried out as a study for the creation of a dramaturgy based on the testimony. From the narrative, which contemplates the artist\'s involvement in experimental psychotherapy based on the psychiatric use of LSD, a parallel is identified between the trajectory of the author and the dynamics of the myth associated with theatrical art - the Greek myth Dioniso - and is reflected on the circumstances in which the creation of his theatrical work took place, focusing on the period of Brazilian historical counterculture. Seeking to outline the notion suggested in Chapter 20 of the book \"The Theater of Alchemy and the Alchemy of Theater,\" the question of \"ritual theater\" is discussed and the alchemical quality of the Dionysian myth is rescued, outlining the notion of a \"Dionysian alchemy\".

No. of bitstreams: 1 Diogo de Lima e Calazans.pdf: 3887746 bytes, checksum: 240e2acdafb6e62450bd00c5f427d721 (MD5) Previous issue date: 2012-05-14 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / The objective of this dissertation is to analyze criticism to Jungian interpretation of Alchemy in the field of History of Science. Considering this discussion, we will also review important historical aspects related to Carl Gustav Jung´s trajectory leading to his encounter with the field of Alchemy. We considered this topic while realizing that many of the hypotheses developed by Jung in the field of Analytical Psychology have an effect on the usual perception of Alchemy, and furthermore, in the field of History of Chemistry itself, as we have found references to C.G. Jung´s work in the works of important historians of science. This research is based on the complete works of Jung, focusing on Psychology and Alchemy, and on a number of books and papers on History of Chemistry. In our analyses, we have found works, whose authors found in C.G.Jung´s hypotheses on the one hand a contribution from Psychology, complementary to the vision of History of Science, and, on the other hand, an incomplete or unsatisfactory model / O objetivo deste trabalho é analisar a crítica à interpretação junguiana da alquimia no campo da historia da ciência. Tendo em vista essa discussão, também passamos em revista importantes aspectos históricos relacionados à trajetória de Carl Gustav Jung rumo ao seu encontro com a alquimia. Consideramos a escolha desse tema ao averiguar que muitas das hipóteses criadas por Jung, no âmbito da psicologia analítica, vêm exercendo efeito sobre a percepção comum da alquimia, assim como no próprio campo da história da química, sendo encontradas referências à obra do psiquiatra nos trabalhos de importantes historiadores da ciência, assim como nas pesquisas de autores de menor expressão. Para a realização desta dissertação fizemos uso das obras completas de Jung, com foco no livro Psicologia e Alquimia, assim como de diversos livros e artigos de estudiosos da história da química. Em nossas análises nos defrontamos com trabalhos de autores que enxergaram nas hipóteses do psiquiatra, desde uma contribuição da psicologia, complementar à história da ciência, até aqueles que o consideraram um modelo incompleto ou insatisfatório

Creating art or vexing nature? : ethics and the manipulation of nature, a critical study of arguments from Nature

Kirkham, Georgina Katharine January 2008 (has links)
This dissertation comprises a series of five separate papers, arranged as chapters, linked thematically and also in their conclusions. The thematic connection between the chapters is that, in each, I investigate some aspect, either historical or contemporary, of how moral limits have been, or might be, applied to the human manipulation of nature through technology. More specifically, I explore how the concept of naturalness has been, and still is, employed in ethical arguments that seek to place limits upon or defend the use of various technologies. In each chapter, I argue that arguments which appeal to nature or naturalness as a normative concept make proper sense only when understood from the perspective of virtue ethics. The conclusions of each chapter are connected, and connected to the conclusions of the dissertation as a whole: firstly, that what I call 'arguments from nature', as they are used in debates about the moral limitations on the use of technology, are defensible only from within a virtue ethics framework; secondly, that such arguments have an important, although limited, role in such debates; and, finally, that virtue ethics more broadly can inform debates about the ethics of technology and the environment. In the first two chapters, by comparing contemporary debates over the ethics of technological manipulation of nature with historical debates over the proper relationship between art and nature, I demonstrate that virtue ethics have played, and still do play, a significant role in our ethical understanding of our relationship with the non-human world. I argue that the ethical issues that arise from our relationship with the non-human world, in response to advances in technology and to problems with the environment, indicate the need for an understanding of ethics that goes further than the mere consideration of rights and utility. In chapters three and four, I argue that virtue ethical theory provides the most promising understanding of the argument from nature as it is applied in attempts to place limits on the human manipulation of nature. In the final chapter, I explore what a modern environmental or technological virtue or vice might be. I explain and defend the environmental and technological virtue of 'living in place' and, in doing so, bring together and validate the claims made in previous chapters that the appeal to human nature does have a role as a normative guide for our ethical evaluations of how we should live and, more generally, that virtue ethical theory can be of guiding and foundational significance in an overarching ethics of the environment and technology.

Characterization And Utilization Potential Of Class F Fly Ashes

Acar, Ilker 01 February 2013 (has links) (PDF)
In this thesis, characterization of two class F fly ashes (FA) from &Ccedil / atalagzi and Sug&ouml / z&uuml / thermal power plants were carried out and their utilization potentials in three different fields were examined. Characterization of sintered samples and determination of their utilization potentials in ceramic industry is the first research area in this thesis. For this purpose, the class F fly ash samples were first pressed into cylindrical specimen without the addition of any organic binders or inorganic additives, and then sintered to form ceramic materials. Effects of sintering temperature and time on sintering characteristics were investigated. In the experiments, the cylindrical specimens were first preheated to 300oC for 1 h to remove moisture and any other gases. The specimens were then fired at the temperatures of 1000oC, 1050oC, 1100oC and 1150oC for the sintering times of 0.5, 1.0, 1.5 and 2.0 hours. Heating rate of 10oC/min was kept constant throughout the experiments. Quality of sintered samples was evaluated in terms of ceramic specifications such as density, water absorption, porosity, shrinkage and splitting tensile strength. In addition, mineralogical and microstructural changes during sintering were determined with X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses. According to literature data, better microstructure, the highest density and strength with the lowest porosity, water absorption and shrinkage values are the indications of the optimum sintering conditions. Based on these specifications, Sug&ouml / z&uuml / fly ash gave better results compared to &Ccedil / atalagzi fly ash, and the optimum conditions were achieved at the sintering temperature of 1150oC for the sintering time of 1.5 hours for both samples. Pozzolanic reactivity of the fly ashes and their utilization potentials in civil engineering applications were also examined in detail during this study. For this purpose, &Ccedil / atalagzi (CFA) and Sug&ouml / z&uuml / (SFA) fly ashes were first subjected to a specific hydraulic classification process developed at CAER (University of Kentucky, Center for Applied Energy Research) to recover ultrafine fly ash particles. The overflow products with average particle sizes of 5.2 &mu / m for CFA and 4.4 &mu / m for SFA were separated from the respective as-received samples with average particle sizes of 39 &mu / m and 21 &mu / m. After the classification stage, the pozzolanic activities of these ultrafine fly ash fractions (UFA) and as-received samples were examined by preparing a number of mortar (mixture of Portland cement (PC), FA or UFA as partial cement replacement, sand and water) and paste (mixture of PC, FA or UFA as partial cement replacement and water) specimens. Control samples containing only PC were also prepared and tested through the experiments for the comparison of the results. In the mortar experiments, three different PC replacement ratios by FA and UFA (10%, 20% and 30%) were used to examine the effects of FA and UFA samples on the fresh and hardened mortar properties such as water requirement, compressive strength, drying shrinkage and water expansion. These mortar tests indicated that ultrafine fractions of &Ccedil / atalagzi (CUFA) and Sug&ouml / z&uuml / (SUFA) fly ashes provided more than 10% reduction in water demand compared to the control sample for 30% PC replacement. The mortar cubes containing CUFA and SUFA samples exhibited also higher strength development rates after 14 days compared to the ones with as-received samples and PC only. At the end of the curing age of 112 days, both CUFA and SUFA provided more than 40% increase in compressive strength compared to the control sample for the PC replacement ratios higher than 20%. As a comparison, SUFA gave better results than CUFA in both water demand and compressive strength tests. The mortar bars prepared with the both FA and UFA samples exhibited very low shrinkage and expansion values. These values decreased generally with increasing PC replacement ratio especially after 14 days. In the paste experiments, thermogravimetric analyses (TGA) of the paste specimens prepared by using only with 20% PC replacement were carried out to determine pozzolanic reactivity of the samples. The difference between the remaining Ca(OH)2 (portlandite) contents in the paste specimens containing the fly ashes and the reference PC paste was used as a measure of pozzolanic reactivity. After 112 days, 68.56% and 62.68% Ca(OH)2 content of PC only pastes were obtained with the pastes containing CUFA and SUFA samples, respectively, corresponding to 11% and 13% more Ca(OH)2 consumptions in reference to the respective as-received samples. X-ray diffraction (XRD) analyses were also performed for comparison of main portlandite peak intensities in the paste specimens containing FA or UFA with those in the PC only paste during cement hydration. According to these XRD analyses, portlandite content in PC/UFA pastes decreased significantly after 14 days compared to the PC only paste. All of these tests and analyses showed that a highly reactive lower cost pozzolan with very fine particle size and higher surface area compared to regular fly ash pozzolans can be produced from both &Ccedil / atalagzi and Sug&ouml / z&uuml / fly ashes using a relatively simple hydraulic classification technology. Cenosphere recovery potentials from &Ccedil / atalagzi and Sug&ouml / z&uuml / fly ashes were also studied in this thesis. Determination of cenosphere content was done under optical microscope by particle counting on the basis of point and area. Based on the point-counting data, CFA and SFA samples originally contain 11.30% and 4.50% cenospheres, respectively. Variations of cenosphere contents in the fly ash samples were examined by using float-sink, screening and air classification tests. The results pointed out that cenosphere contents decreased with decreasing size and increasing density for both samples. According to the float-sink tests, &Ccedil / atalagzi fly ash has much more floating products and more cenospheres than Sug&ouml / z&uuml / fly ash for the same density interval. Based on the air classification results, cenospheres were concentrated in the underflow products, and cenosphere contents increased with increasing air pressure and decreasing motor speed for both samples. The most efficient cenosphere separation technique among the examined methods was screening. Cenosphere contents of CFA and SFA increased to 21.65% and 11.83%, respectively by only using simple screening through 38 &mu / m.

Cap Rock Integrity In Co2 Storage

Dalkhaa, Chantsalmaa 01 August 2010 (has links) (PDF)
One way to reduce the amount of CO2 in the atmosphere for the mitigation of climate change is to capture the CO2 and inject it into geological formations. The most important public concern about carbon capture and storage (CCS) is whether stored CO2 will leak into groundwater sources and finally into the atmosphere. To prevent the leakage, the possible leakage paths and the mechanisms triggering the paths must be examined and identified. It is known that the leakage paths can be due to CO2 - rock interaction and CO2 &ndash / well interaction. The objective of this research is to identify the geochemical reactions of the dissolved CO2 in the synthetic formation water with the rock minerals of the Sayindere cap rock by laboratory experiments. It is also aimed to model and simulate the experiments using ToughReact software. Sayindere formation is the cap rock of the Caylarbasi, a southeastern petroleum field in Turkey. The mineralogical investigation and fluid chemistry analysis of the experiments show that calcite was dissolved from the cap rock core as a result of CO2- water- rock interaction. Using the reactive transport code TOUGHREACT, the modeling of the dynamic experiment is performed. Calcite, the main primary mineral in the Sayindere is dissolved first and then re-precipitated during the simulation process. The decreases of 0.01 % in the porosity and 0.03% in permeability of the packed core of the Sayindere cap rock are observed in the simulation. The simulation was continued for 25 years without CO2 injection. However, the results of this simulation show that the porosity and permeability are increased by 0.001 % and 0.004 %, respectively due to the CO2-water-rock mineral interaction. This shows that the Sayindere cap rock integrity must be monitored in the field if application is planned.

Post tenebras spero lucem : Alquimia y ritos en el Quijote y otras obras cervantinas

Magriñá Badiella, Carles January 2014 (has links)
This study focuses on two areas: alchemy (Part I) and rituals of initiation (Part II) in the works of Miguel de Cervantes, focusing on Don Quijote de la Mancha as my main case study. The first part analyses the function of alchemy and how it can be interpreted throughout the works and various literary genres of Cervantes. It will demonstrate that the texts of Cervantes contain both explicit and implicit allusions to, as well as different aspects of alchemy, such as operative and spiritual alchemy and how these are ultimately used by Cervantes as a means of expression. The author draws from this rich source and modifies these means of expression in order to achieve various results: sometimes with wit or in relation to fraud; at other times it focuses on inner alchemy relating to chivalry in what I have called spiritual chivalry, which has the aim of self-improvement and ultimately, gnosis.  Regarding the chivalric rituals of initiation, according to this investigation chivalry serves as both satire and representation of the alchemical process in the case of Don Quijote, which finds its key moments during the rituals. In this sense alchemy and chivalry are studied as two sides of the same coin, in which the search for something higher, an object (the philosopher stone, the beloved), subjects the protagonist to continuous transmutations and puts him in contact with the transitory, that is, liminal states, people and spaces. From this perspective Don Quixote de la Mancha is built upon liminal poetics. My approach, which follows the tenets of analogical hermeneutics, is included within the framework of the Western Esotericism Studies. The 16th and 17th centuries were a fertile age for alchemy throughout Europe. In Spain, alchemy and other esoteric disciplines co-existed with the Spanish Inquisition and its body for the control of ideas and texts: censorship. By being ambiguous and putting into dialogue different ideas of alchemy, Cervantes not only allowed readers to reach their own conclusions, he also protected his work from censorship.

Synthesis Of Ferrocenyl Substituted Pyrazoles

Gormen, Meral 01 July 2005 (has links) (PDF)
Pyrazoles have been studied for over a century as an important class of heterocyclic compounds and continue to attract considerable interest due to the broad range of biological activities they possess. The incorporation of the essential structural features of pyrazoles with a ferrocene moiety could provide new derivatives with unexpected and/or enhanced biological activities since several ferrocene derivatives have already been shown to be active against a number of tumors. For this reason, we investigated the synthesis of ferrocenyl-substituted pyrazoles, such as 1-alkyl/aryl-5-ferrocenylpyrazoles, by employing the reaction between (2-formyl-1-chlorovinyl)ferrocene and hydrazine derivatives. Although this reaction is known, it was not studied in much detail and the low yields of ferrocenyl pyrazoles were obtained. Thus, we have reinvestigated this reaction and improved the yields of pyrazoles by optimizing the reaction conditions. (2-Formyl-1-chloro vinyl)ferrocene was first reacted with the excess amount (3 equivalents) of hydrazine derivative at 25 0C in dioxane under argon for 2 hours, and the resulting mixture was then heated at 100 0C for 6 hours in the same solvent. Under our optimized conditions, these reactions afforded 1-alkyl/aryl-5-ferrocenylpyrazole derivatives in moderate to good yields as a single or major product of the reaction. In some cases, 1-alkyl/aryl-3-ferrocenylpyrazole derivatives resulted from these reactions as very minor products.

A ALQUIMIA DA PALAVRA: FERNANDO PESSOA E AS CIÊNCIAS OCULTAS. / THE WORD S ALCHEMY: FERNANDO PESSOA AND THE OCCULT SCIENCES

Oliveira, Anderson Amaral de 21 December 2011 (has links)
Fernando Pessoa has changed his country s culture driving his nation to a vanguard position on modern culture. He abdicated enjoying life to transform it into his work, built up considering the author s deep knowledge in theories of occult sciences, making alchemy and occultism an important authorial strategy, transforming his knowledge to an esthetic resource for his work, from the very first until the last poem as the biggest alchemic work ever seen in a literature. Such realization maybe doesn t have the same effects for the occult sciences, however its symbolic, metaphoric and analogical power depurate the literature, at the same time, it looks towards to sublimate the poet s life through his work. / Fernando Pessoa modificou radicalmente a cultura de seu país, levando sua nação para a posição de vanguarda na cultura moderna. Abdicou de gozar sua vida para transformá-la na sua obra que foi construída levando em consideração seus vastos conhecimentos de teorias das ciências ocultas, fazendo da alquimia e do ocultismo uma importante estratégia autoral, transformando-os em recurso estético para sua obra que pode ser vista do primeiro ao último poema como o maior tratado de alquimia em uma obra literária. Tal realização talvez não tenha grandes efeitos dentro das ciências ocultas, mas seu poder simbólico, metafórico e analógico depura a literatura, ao mesmo tempo em que busca sublimar a vida de um poeta através de sua obra.
