Teatro galego e construción nacional : os Cadernos da Escola Dramática Galega (1978-1994)

Garcia-Vidal, David January 2010 (has links)
Taking Itamar Even-Zohar’s ‘polisystem theory’ and Pierre Bourdieu’s ‘theory of the field of cultural production’ as a starting point, the objective of this research is to analyse the development of Galician theatre and the re-configuration of the literary system during the period of institutionalization of the Galician culture after Franco’s death and the coming of democracy and political autonomy. By studying the 105 Cadernos published by the Escola Dramática Galega between 1978 and 1994, which cover a wide range of literary activities, the conflicts and tensions between different models and repertoires as well as the position and the contradictions of the Escola Dramática Galega during that process are brought to light. Gonzalez Millán’s theoretical concepts of ‘literary nationalism’ and ‘national literature’ will be useful in order to analyse the role that drama had on the nation-building process in Galicia and the consequences that that fact had on the development of the system. Conclusions are also drawn concerning the determinations imposed on the development of contemporary drama by the historical subsidiary position of the Galician literary system.

Chuva braba : o testemunho Claridoso de Manuel Lopes

Costa, Elga Cristina Vilela Viana Pereira da January 2002 (has links)
The thesis aims to bring together the combined knowledge and research currently available relating to Manuel Lopes and his literary production, and seeks to provide further insight into the testimony of the author Manuel Lopes and his role and purpose within the Claridade movement. The study analyses the everyday reality of the Cape Verde Islands, its people and lands, and this is compared with the author's fictional representation, the characters, the principal themes, the author's main preoccupation with his fellow islanders, his style, and his purpose of supplanting the traditional literary theme of emigration with a radically new but simple one: the option of staying on the islands. The seven chapters of this study start with a theoretical discussion introducing the history of Cape Verde, the phenomenon of emigration as a constant of everyday existence on the islands, the four major waves of this constant exodus and their causes and consequences. This is followed by a brief biographical portrait of the author and then a discussion of how his own experiences brought him to explore the facts of life on the islands and insert them into his central literary themes. The literary portrayal of these realities, setting man's great love for the land against the ambiguous call of emigration, would thus lead him to lay down the bases for a new definition of Cabo-verdianidade. This leads into a general discussion of the new Claridade generation of writers, of which Lopes was a major exponent. Chapter six presents an analysis of the work Chuva Braba focusing on the characters who influence the protagonist Mané Quim either for or against leaving, thus revealing a clear pattern whereby the main theme of emigration becomes a debate between Partir and Ficar, between an abandonment of the islands and a new sense of loyalty towards the land of their birth.

Configurations identitaires dans Cascalho et Além dos marimbus de Herberto Sales / Identity configurations in Cascalho and in Alem dos marimbas by Herberto Sales

Garcia, Frédéric Robert 18 December 2013 (has links)
Ce travail est centré sur l’œuvre de l’écrivain baianais Herberto Sales et se propose d’analyser les éléments constitutifs de l’univers de la Chapada Diamantina en tant que construction identitaire de l’individu et de son milieu. Nous soulignons l’importance de l’étude de l’identité dans la littérature brésilienne, plus précisément celle de la région de Bahia, à travers les romans Cascalho et Além dos marimbus qui constituent le corpus de la recherche. Cette étude prétend démontrer comment se manifeste la mise en place d’un dialogue entre la littérature et les autres discours sociaux, dans une perspective interdisciplinaire. Nous étudions la place de l’auteur dans le contexte de la littérature brésilienne, le « projet littéraire de Herberto Sales ». Nous nous penchons sur les formes sociales des constructions identitaires et leurs relations avec le pouvoir. Nous soulignons en particulier comment s’articulent la connivence et la réciprocité avec l’Etat dans ces interrelations et comment se met en place le réseau de soutien du « coronelato » à travers un projet légitimant. Nous analysons également les constructions identitaires sous le jour de l’importante contribution de l’oralité, des mythes, des croyances populaires et de leur poids dans la culture locale. Nous abordons les représentations du territoire dans l’univers romanesque de la Chapada diamantina, territoire de « passage » qui représente un croisement de plusieurs cultures et incarne aussi bien une image de terre promise, Eldorado, que celle d’un enfer sur terre. Enfin, nous mettons en avant les différentes représentations de la nature et la dimension épique des romans / Centered on the works of Baian writer Herbert Sales, this dissertation aims to analyze the founding elements of the universe of Chapada Diamantina as identity construction of the individual and his environment. We emphasize the importance of the study of the identity in the Brazilian literature, specifically the literature of Bahia through the analysis of the two novels that constitute the corpus of this research : Cascalho and Além dos marimbus.This study aims to demonstrate how dialogue is etablished between literature and other social discourses, from an interdisciplinary perspective. We highlight the place of the author in the context of Brazilian literature : the " literary project of Herbert Sales ". We analyse the social forms of identity constructions and their relation to the power, collusion and reciprocity of the state in these interrelationships, and how the support network to "coronelato" is articulated towards its legitimating project. We also focused on the identity constructions through the important contribution of orality, myths and popular beliefs in the local culture. We address the representations of territory in the fictional universe of Chapada diamantina, as a crossing space of diverse cultures, “territory of passage”, which embodies both the Eldorado and hell on earth. Finally, we highlight the different representations of nature and its epic dimension in the novels under analysis

A study on wireless communication error performance and path loss prediction

Isnin, Ismail January 2011 (has links)
One channel model that characterises multipath fading effect of a wireless channel is called Flat Rayleigh Fading channel model. Given the properties of Flat Rayleigh Fading channel, an equation to find the capacity of a Flat Rayleigh fading channel with hard decision decoding is derived. The difference of power requirement to achieve the Additive White Gaussian Noise (AWGN) capacity over a Flat Rayleigh Fading channel fading is found to increase exponentially with Es /N0 . Upper and lower bounds of error performance of linear block codes over a Flat Rayleigh Fading channel are also studied. With the condition that the excess delay of a channel is known earlier, it is shown that a correlator with shorter length, according to excess delay of the channel, can be constructed for use in wireless channel response measurements. Therefore, a rule of construction of a shorter length correlator is defined, involving concatenation of parts of a Constant Amplitude Zero Auto-Correlation (CAZAC) sequence. Simulation of [136,68,24] Double Circulant Code with Dorsch List Decoding is also done in order to evaluate error performance of the channel coding scheme over one of the IEEE Wireless Metropolitan Area Network (WirelessMAN) channel models, the Stanford University Interim Channel Model No. 5 (SUI-5) channel. Performance of the channel cod- ing was severely degraded over the SUI-5 channel when it is compared to its performance over the AWGN channel. Indoor path losses within three multifloor office buildings were investigated at 433 MHz, 869 MHz and 1249 MHz. The work involved series of extensive received signal strength measurements within the buildings for all of the considered frequencies. Results have shown that indoor path loss is higher within a square footprint building than indoor path loss in a rectangular building. Parameters of Log-Distance Path Loss and Floor Attenuation Factor Path Loss models have been derived from the measurement data. In addition, a new indoor path loss prediction model was derived to cater for path loss pre- diction within multifloor buildings with indoor atriums. The model performs with better prediction accuracy when compared with Log-Distance Path Loss and Floor Attenuation Factor Path Loss models.

A Parametric Study On Hydrothermal Synthesis Of Zinc Oxide Nanowires With Various Zinc Salts

Akgun, Mehmet Can 01 March 2012 (has links) (PDF)
ZnO is a promising semiconducting material for manufacturing optoelectronic devices. Its most important properties are its wide and direct band gap and its high electron-hole binding energy. Synthesis of ZnO in bulk and thin film form has been investigated intensively over recent decades. Likewise, nanomaterials have been in the point of focus for their different properties compared to their bulk form. The vastly increased ratio of surface area to volume and change in electronic properties with great reduction in particle size enable improved performance in conventional applications where their bulk counterparts have been used for decades. As a result of this trend, research on synthesis of ZnO nanowires and their incorporation in prototype optoelectronic devices has been intensive in recent years. Therefore, synthesis of ZnO nanowires in a cost effective way and understanding the factors influencing the ZnO nanowire growth is essential for contribution to ongoing research. V In this thesis, hydrothermal synthesis of ZnO nanowires, which is a solution based method enabling vertically aligned ZnO nanowire array fabrication over large areas, is investigated. In the first part of this thesis, the effect of using various zinc salts as zinc sources on ZnO nanowires is investigated by monitoring pH, temperature and light transmittance of growth solutions. In the second part, a detailed parametric study on the use of zinc acetate dihydrate salt is provided with regard to the existence of its unique properties compared to other two zinc salts. The effect of growth time, temperature, ratio of concentration of precursor chemicals and precursor chemical concentrations is investigated. The results show that hydrothermal synthesis method could replace the conventional ZnO nanowire fabrication methods. It was shown that specific nanowire lengths for any application can be obtained simply by adjusting the parameters of hydrothermal growth system.

An Archaeometric Application To A Group Of Early Ottoman Ceramics From Iznik

Kirmizi, Burcu 01 September 2004 (has links) (PDF)
This study investigates the physical, mineralogical and chemical characteristics of a group of pottery sherds that are mostly Miletus-ware ceramics, belonging to the Early Ottoman period and excavated during 2003 season, from the The sherds examined are mostly characterized by cobalt-blue designs which are occasionally coupled with black, green and purple paintings. After grouping the sherds according to their stylistic and color differences / petrographic, X-ray diffraction, scanning electron microscope coupled with energy dispersive X-ray and Fourier Transform Infrared analyses were carried out for investigating the mineralogical and chemical properties. Most of the ceramic samples have slip and glaze on both sides. The glaze part is mostly fresh without any devitrification products. Bodies of the ceramics have tones of reddish yellow and/or red, indicating abundant amount of iron in their raw material. Grains consist mainly of metamorphic rock fragments (quartz-mica schist), quartz, feldspar, hornblende, hematite and biotite. Pyroxene, epidote, chert, muscovite, opaque minerals, chlorite are also encountered. Micritic calcite occurs in some of the pores. Ceramic bodies investigated are usually fine-grained and well-sorted. Clay raw material used for the production of the ceramics seems to be originated from a metamorphic source. Bodies usually show a low degree of vitrification with few exceptions, indicating a rather simple technology with non-uniform and low degree of firing, probably not exceeding 900&deg / C. Technological characteristics of the sherds examined do not seem to have changed much between 14th and 16th century.

Synthesis Of Mfi Type Zeolite Membranes In A Continuous System

Culfaz, Pinar Zeynep 01 July 2005 (has links) (PDF)
MFI type zeolites, are the most widely studied zeolites for membrane separations. Conventionally, zeolite membranes are prepared in batch systems by hydrothermal synthesis in autoclaves. This method has several disadvantages for use in industrial scale for the synthesis of membranes with large areas and complex geometries that are commonly used in membrane modules. The objective of this study is to prepare MFI type zeolite membranes on tubular alumina supports in a continuous system where the synthesis solution is circulated through the tubular supports. Syntheses were carried out using clear solutions, at atmospheric pressure and at temperatures below 100&deg / C. The membranes were characterized by N2, SF6, n-butane and isobutane permeances, X-ray diffraction and scanning electron microscopy. A 2-&amp / #956 / m membrane was synthesized using the composition 80SiO2: 16TPAOH: 1536H2O at 95&deg / C in the continuous system. The membrane showed N2 permeance of 4.4 x 10-7 mol/m2.s.Pa and N2/SF6 selectivity of 11. The membrane synthesized in the batch system showed a N2 permeance of 3.4 x 10-7 mol/m2.s.Pa and a N2/SF6 selectivity of 27. Both membranes showed n-butane/isobutane mixture (50%-50%) selectivities of about 6 at temperatures of 150 and 200&deg / C. Among many zeolite membranes reported in literature, these membranes are one of the few zeolite membranes synthesized in a flow system and the first MFI type membranes synthesized in a continuous flow system with circulation of the synthesis solution. The permeances and selectivities of the membranes synthesized in the continuous system are comparable with the MFI type membranes synthesized in batch systems in literature.

Synthesis And Characterization Of Clinoptilolite

Guvenir, Ozge 01 August 2004 (has links) (PDF)
Clinoptilolite is the most abundant zeolite mineral in nature. In this study a reproducible synthesis recipe for clinoptilolite was established and the limits of the crystallization field were developed by changing synthesis parameters such as temperature, composition and the nature of reactants. Clinoptilolite was reproducibly synthesized as a pure phase and in high yield at 140oC using a benchmark batch composition of 2.1 Na2O:Al2O3:10SiO2:110.1 H2O. Clinoptilolite was crystallized from 10wt% or 28wt% seeded systems while it was not formed if no seeds were present. Clinoptilolite was also crystallized as a pure phase when the cation in the benchmark batch composition was Na,K mixture, or when alkali salts such as carbonates or chlorides were used besides alkali hydroxides, or when the SiO2/Al2O3 ratio was in the range of 10-12. Clinoptilolite was still crystallized as a single phase when alkali hydroxides in the batch were reduced by 20%. With the benchmark batch composition, clinoptilolite was crystallized in pure phase form at 100oC, 120oC, 140oC and 160oC while synthesis at 175oC resulted in the formation of pure mordenite. At 140oC clinoptilolite was crystallized together with Linde L when cation in the benchmark composition is only potassium. Phillipsite crystallized together with clinoptilolite at SiO2/Al2O3 ratio of 8 to 9. At SiO2/Al2O3 ratios of 6 or 4, phillipsite or analcime was formed as pure phase respectively. When the alkali hydroxides in the batch was increased by 20%, sanidine was formed. Use of reactive aluminosilicate gels enhanced the formation of clinoptilolite while attempts to use mineral raw materials were unsuccessful. For both Na and (Na,K)-clinoptilolite, Si/Al ratio of products were greater than four. Thermal stability of synthetic clinoptilolites were comparable with natural clinoptilolite and potassium ion increased thermal stability of clinoptilolite.
