Partindo desse contexto hist?rico como cen?rio, temos as obras liter?rias Malinche (2005) e In?s del alma m?a (2006), narrativas de extra??o hist?rica escritas por Laura Esquivel e Isabel Allende, respectivamente, que apresentam um olhar voltado para figuras femininas que participaram de modo significativo na ocupa??o do M?xico e do Chile pelos espanh?is. A presen?a de protagonistas femininas ? um tra?o recorrente em ambas as escritoras latino-americanas e, no caso das narrativas que nos propusemos analisar, esta caracter?stica se mant?m, acrescida da mem?ria como elemento fundamental na constru??o dos textos. Desse modo, buscamos neste trabalho, analisar como Esquivel e Allende constroem suas narrativas dando voz ? mulher como protagonista na conquista da Am?rica e como o abandono, presente na vida de Malinalli e In?s Su?rez, influenciou significativamente seus destinos, deixando marcas em suas mem?rias, elementos que s?o resgatados pelas autoras.

Este trabajo de carácter empírico documenta la presencia de la forma de tratamiento su merced durante el siglo XIX, en particular, en textos literarios latinoamericanos que representan el habla de africanos y de sus descendientes, tomados de Lipski (2005a, 2005b), y en textos literarios presentes en CORDE. El texto muestra también otros usos de su merced ligados a contextos de comunicación oficial escrita a partir de estudios anteriores. Asimismo, en este trabajo, se revisa la bibliografía sobre la forma en cuestión, se documenta el uso de su merced y se concluye que esta forma de tratamiento aparece en el contexto de relaciones sociales asimétricas y, muy marcadamente, en variedades de español habladas por africanos o descendientes de africanos en el siglo XIX.AbstractThis paper is an empirical study of the presence of the address form su merced in the XIX century, particularly in Latin American literary texts representing the speech of Africans and their descendants, based on examples taken from Lipski (2005a, 2005b) and texts included in CORDE. Based on data found in other corpora, the discussion also includes uses of su merced in official written communication. It reviews earlier studies about su merced in Latin America and concludes that this address form appears in the context of asymmetrical social relations between groups and especially in the speech of Africans and their descendants.Keywords: su merced – Bozal Spanish – XIX century – language contact

Os fundamentos para os métodos algébricos unidimensionais baseados na álgebra de momentum angular su(2)(clássica e deformada) são apresentados numa forma adequada à descrição de vibrações moleculares de sistemas diatômicos e de sistemas poliatômicos planares com simetria C_{2v}. Aplicações detalhadas envolvendo os estados vibracionais e seus respectivos potenciais foram exaustivamente desenvolvidas para os dois primeiros estados eletrônicos (A-X Sigma) dos sistemas diatômicos LiH (e seus isotopômeros), NaH, KH, RbH, CsH, e Li2. Alguns outros estados eletrônicos mais excitados também foram analisados algebricamente. Os potenciais vibracionais semi-clássicos foram calculados via estados coerentes do grupo SU(2). Calculamos também fatores de Franck-Condon usando as autofun{ções de Morse diretamente, sem qualquer necessidade de linearizações. O presente trabalho é a análise algébrica mais detalhada até o momento sobre moléculas diatômicas, pois envolve um grande número de moléculas distintas e seus estados eletrônicos excitados, os quais ainda não haviam sido analisados algebricamente. Além disto, outras propriedades físicas, como os fatores de Franck-Condon e potenciais vibracionais foram discutidos aqui em detalhes pela primeira vez. O propósito deste trabalho foi de servir como um laboratório para futuras aplicações de modelos algébricos unidimensionais a sistemas moleculares maiores, onde suas potencialidades e, principalmente, suas limitações pudessem ser testadas de forma clara. Além disto, devemos destacar também o aumento expressivo na quantidade de trabalhos sobre moléculas diatômicas e triatômicas devido à importância destas em questões de interesse mundial, como o efeito estufa, e questões de relevância acadêmica, como a espectroscopia em tempo real e de moléculas frias.

Para apreender a conjuntura inserida com a Política Nacional de Resíduos Sólidos no âmbito municipal, foi feita uma explanação do contexto nacional, seguido dos desdobramentos no Estado do Rio de Janeiro, para assim chegar ao município de Paraíba do Sul. Por serem os municípios os principais responsáveis pela implementação da lei, que esse estudo visa compreender como a questão socioambiental dos resíduos sólidos urbanos foi sendo delineada no município e de que modo se aproxima das exigências estabelecidas pela nova legislação. Para isso, foram feitos levantamentos bibliográficos sobre os conceitos norteadores da presente pesquisa e os contextos fundamentais, seguido de uma contextualização da gestão de resíduos sólidos urbanos e dos desdobramentos da Política Nacional de Resíduos Sólidos a partir de dados oficiais disponibilizados pelos órgãos estatais públicos. A pesquisa empírica foi ordenada através de visitas à Secretaria do Ambiente e Desenvolvimento Agrário municipal e ao lixão, sendo acompanhadas de entrevistas semiestruturadas e observações sistematizadas. Os resultados obtidos revelam o quão distante encontra-se a realidade do município diante das prerrogativas exigidas pela Lei nº 12.305/10. As dificuldades técnicas e financeiras apontadas pelos gestores públicos de Paraíba do Sul expressam as desarticulações que atravessam a estruturação da Política Nacional de Resíduos Sólidos. No aspecto social, foram observados os grandes desafios que perpassam os órgãos públicos, no que tange a reorganização do trabalho dos catadores de materiais recicláveis, conforme preconiza a legislação. Contudo, verifica-se a necessidade premente de um reordenamento das diretrizes que orientam a Lei nº 12.305/10, de modo articulado e coerente com as diferentes realidades socioambientais, já que sozinho dificilmente o município será capaz de atender aos ditames proclamados pela lei. Enquanto as diferentes instâncias da Federação não assumirem seus compromissos de forma eficiente, dificilmente a PNRS tornar-se-á uma realidade nacional. / This work addresses the socio-environmental issue of municipal solid waste in the city of Paraíba do Sul / RJ, through interfaces with the National Solid Waste Policy, sanctioned by Federal Law 12.305, in August 2010. In order to understand the conjuncture inserted with the National Solid Waste Policy at the municipal level, an explanation was made of the national context, followed by the developments in the state of Rio de Janeiro, to reach the municipality of Paraíba do Sul. The municipalities are the main responsible for the implementation of the law, which this study aims to understand how the socio-environmental issue of solid urban waste has been delineated in the municipality and how it approaches the requirements established by the new legislation. For this, bibliographical surveys were carried out on the guiding concepts of the present research and the fundamental contexts, followed by a contextualization of the solid urban waste management and the unfolding of the National Solid Waste Policy from official data made available by the public state agencies. The empirical research was ordered through visits to the Secretariat of the Environment and Agrarian Development municipal and to the dump, being accompanied by semi-structured interviews and systematized observations. The results show how distant the city reality is in the face of the prerogatives required by Federal Law 12.305 / 10. The technical and financial difficulties pointed out by the public managers express the dislocations that cross the structuring of the PNRS. In the social aspect, the great challenges that the public agencies, in relation to the reorganization of the work of the collectors of recyclable materials, were observed, according to the legislation. However, there is a pressing need for a reorganization of the guidelines that govern Federal Law 12.305 / 10, in a way that is articulated and coherent with the different socio-environmental realities, since it is difficult for the municipality alone to comply with the dictates proclaimed by law. As long as the different instances of the Federation do not take their commitments efficiently, the PNRS will hardly become a national reality.

In this thesis, we introduce EPOSIC channels, a class of SU(2) -covariant quantum channels. For each of them, we give a Stinespring representation, a Kraus representation, its Choi matrix, a complementary channel, and its dual map. We show that these channels are the extreme points of all SU(2) -irreducibly covariant channels. As an application of these channels to the theory of quantum information, we study the minimal output entropy of EPOSIC channels, and show that a large class of these channels is a potential example of violating the well-known problem, the additivity problem. We determine the cases where their minimal output entropy is not zero, and obtain some partial results on the fulfillment of their entanglement breaking property. We find a bound of the minimal output entropy of the tensor product of two SU(2) -irreducibly covariant channels. We also get an example of a positive map that is not completely positive.

Shan’ge 山歌 is a collection of popular songs in Wu dialect by the late Ming scholar Feng Menglong 冯梦龙 (1574-1646). Due to a lack of detailed literary analysis of the songs, and a lack of appreciation of these songs from the perspective of rhetorical aesthetics, I aim to provide a close reading of the siqing (私情) songs in Shan’ge. With the intention to offer a fresh perspective into the depiction of emotions and sentimental feelings, as well as the various ways of presenting the people’s perception of love and sexual desire in these songs, I endeavor to both enrich the understanding of Shan’ge and call critical attention to the subject mater of siqing. In my thesis, I argue that these Siqing songs are strong spokesmen and representatives of genuineness promoted by Feng Menglong in the preface of Shan’ge. I will examine how genuineness was promoted by the late Ming scholars and particularly, how Feng Menglong views genuineness and how he utilizes genuineness in the songs as a means to promote vernacular literature. The representative siqing songs will be categorized and explored in three sections, with the purpose of answering the following questions: How could Feng’s promotion of these popular songs be situated in the late Ming discourse of genuineness? How does Shan’ge vividly create a world that not only celebrates true and romantic love but also allows the display of the vent of irresistible desire, and the rustic expression of sex? How are carriers of genuine qing explicitly portrayed in these songs through their ingenious conversations and tricks in love affairs? And lastly, how do the songs in different ways showcase a vivid and dynamic picture of a sexually liberate and joy-oriented late Ming Suzhou?

Microfluidic paper-based analytical devices (microPADs) are an emerging platform for point-of-care diagnostic tests for use by untrained users with potential applications in healthcare, environmental monitoring, and food safety. These devices can be developed for a multitude of different tests, many of which employ enzymes as catalysts. Without specialized treatment, some enzymes tend to lose their activity when stored on microPADs within 48 hours, which is a major hurdle for taking these types of devices out of the laboratory and into the real world. This work focused on the development of simple methods for stabilizing enzymes by applying polymers to chromatography paper. The longterm stabilization was exlored and SU-8 of various concentrations was found to stabilize horseradish peroxidase for times in excess of two weeks. A variety of microPAD fabrications, enzyme dispensing methods, and substrate delivery techniques were explored.

Stable Unbonded Fibre Reinforced Elastomeric Isolators (SU-FREI) have been investigated extensively for seismic applications, with over 20 years of literature supporting their use in isolation of structures as an alternative to conventional Steel Reinforced Elastomeric Isolators (SREI). Preliminary investigations have been conducted into their potential use as bridge bearings, where they could provide an alternative to unreinforced and steel reinforced elastomeric bearings. SU-FREI offer a number of potential advantages in this application relative to SREI, including compactness due to thinner reinforcement layers, ease of installation, rotational tolerances, and ease of manufacture. Recently, SU-FREI have been installed under certain highway bridges along the 407 ETR where the previous unreinforced elastomeric bearings had experienced failure. Monitoring has been conducted by Associated Engineering for the 407 ETR Corporation. Data was collected from this monitoring program and field visits have been conducted to observe the condition of the bearings. The original design process used for the SU-FREI bearings has also been reviewed. The monitoring data was compared against design calculations, and the behavior of the SU-FREI analysed to determine whether they meet performance expectations and are suitable for further use as bridge bearings. It was found that some SU-FREI had experienced degradation, including the appearance of an unidentified liquid. The causes of deterioration were investigated and postulated to be primarily related to design limitations imposed by the geometry of the bridges, original design calculation assumptions, and installation issues. Where these factors were not present, the SU-FREI bearings were found to have experienced little to no deterioration. Furthermore, it was determined through comparative design calculations that the FREI outperformed equivalent SREI with regard to rotational capacity. Recommendations have been developed for future deployment of SU-FREI as bridge bearings. Based on the results of initial deployments, larger-scale employment of SU-FREI in this application should be considered. / Thesis / Master of Applied Science (MASc) / Concrete and steel bridges deform due to temperature changes, traffic motion, and other factors. To allow these deformations without inducing large forces or damage, bearings are employed between the bridge deck and supports. One type of bearing consists of alternating layers of rubber and steel: steel strengthens the bearing, while the rubber provides lateral and rotational flexibility. A relatively new type of bearing has been developed and tested that replaces the steel layers with carbon fibre. Recently, several of these new SU-FREI bearings have been installed on actual highway bridges. The focus of this thesis is on the performance of SU-FREI installed as bridge bearings. The goal was to observe their performance, identify any unexpected behavior, and create recommendations for future consideration whenever SU-FREI are to be used as bridge bearings. Generally, it was found that their performance is satisfactory provided they are designed and used appropriately.

This dissertation presents a method for fabricating integrated hollow and solid optical waveguides on planar substrates. These waveguides are antiresonant reflecting optical waveguides (ARROWs), where high-index cladding layers confine light to hollow cores through optical interference. Hollow waveguides that can be filled with liquids or gases are an important new building block for creating highly-integrated optical sensors. The method developed for fabricating these integrated waveguides employs standard processes and materials used in the microelectronics industry, allowing for parallel, low-cost fabrication. Dielectric cladding layers are deposited on a silicon wafer using plasma-enhanced chemical vapor deposition (PECVD). After the lower cladding layers have been deposited, a sacrificial material is deposited and patterned using photolithography to produce the hollow-core shape. After the sacrificial cores are defined, they are coated with additional PECVD dielectric layers to form the sides and tops of the waveguides. Integrated solid-core waveguides can be easily created by etching a ridge into the top dielectric cladding layer. Finally, the ends of the sacrificial cores are exposed and removed with an acid solution, resulting in hollow waveguides. Improved optical performance for integrated ARROW platforms can be achieved by only using a single over-coating for the cladding on the sides and top of the hollow waveguide. Such a structure resulted in 70% improvement in optical throughput for the platforms and increased sensitivity for optical manipulation and fluorescence detection of single particles, including viruses. Reduced loss for the hollow waveguides can be obtained by surrounding the core with a terminal layer of air on the sides and top of the waveguide. Such devices were created by forming the hollow waveguides on top of a pedestal on the silicon substrate. This process produces the ideal geometry for hollow ARROW waveguides, and loss measurements of waveguides with air-filled cores had loss coefficients of 1.54/cm, which is the lowest achieved for air-core ARROWs.
