Full textThe aim of this dissertation is to show that theater is an effective way of selfrepresentation as well as a powerful weapon used in order to subvert hegemonic values. When considering contemporary drama, mainly the one produced by the so-called minority groups, it is possible to find several authors who made of their works site for protest against oppression, violence and discrimination imposed by the excluding colonial discourse. One clear example of such a work is the play A Raisin in the Sun written by the African-American writer Lorraine Hansberry. The author shows that theater can represent a possibility for the historically excluded groups to bring into public awareness the situation of oppression lived by their community, protesting against it and subverting the hegemonic discourse which tends to value just canonical works and stories. In contemporary times, many stories/histories taken for a long time as marginal or ex-centric, such as the African-Americans for example, became known through transgressive and subverting productions that came out as an attempt to express the self, giving voice to groups so far excluded - or as Hutcheon referred to them, marginalized - rewriting their stories/histories. After some initial considerations related to the theory of drama, we intend to highlight some of the challenges that the Other faces while searching for his/her identity and better opportunities promised by the American Dream in the play A Raisin in the Sun. We also intend to present some of the challenges presented by such work during the translation process due to its strong cultural peculiarities. Besides, we intend to discuss some of these challenges to be faced by Intercultural Translation in A Raisin in the Sun

Full textEste trabalho pretende analisar as peças A Raisin in the Sun, de Lorraine Hansberry, Dutchman, de Amiri Baraka, e Blues for Mister Charlie, de James Baldwin, concernente a performance da masculinidade afro-americana de seus protagonistas homens. Escritas no ápice dos Movimentos dos Direitos Civis da década de sessenta nos Estados Unidos, estas peças carregam uma crítica forte sobre a sociedade americana em geral, o que permite uma percepção mais clara dos obstáculos, reações e conciliação envolvidos na construção da maturidade masculina do homem afro-americano. Para fundamentar esta pesquisa foi necessário revisitar os estudos de gênero para localizar os problemas da construção de masculinidade referente à questão das masculinidades hegemônicas. Somente após a observação dos padrões relativos às delimitações das masculinidades hegemônicas dos brancos na sociedade americana é que as masculinidades subjugadas, assim como a dos afro-americanos, podem ser delimitadas e compreendidas. A construção de masculinidades a que os personagens Walter Jr., Clay e Richard se submetem exemplificam a teoria usada na observação e descrição dos obstáculos e reações que os homens afro-americanos encaram para alcançar sua maturidade como homens. Cada personagem, a sua maneira, confronta obstáculos semelhantes, assim como reage a eles de forma similar, ilustrando um padrão para os obstáculos e reações dos homens afro-americanos na construção da masculinidade negra. Além disso, o processo é doloroso para os personagens nas três peças, e a dor causada, muitas vezes, só cessa com a morte. Não obstante, é no processo de cura das feridas que se evidencia o aspecto mais paradoxal, pois é justamente no suporte oferecido pela figura feminina de suas mulheres, que eles finalmente alcançam sua maturidade como homens

Full textThe study takes into account the polyphenolic composition of Meriot, Cabernet-Sauvignon and Tannat grapes and wines fTom vineyards located in the South of Uruguay. Different cultural and environmental situations were considered, including vines conducted in lyre and trellis in the three varieties, cluster thinning in veraison in Meriot and Cabernet-Sauvignon and cordon Royat pruning and Guyot pruning in Tannat lyre. Tannat grapes presented the highest contents of sugar, total polyphenols, total and extractable anthocyanins, non-acylated and coumarylic anthocyanins. Tannat wines presented the highest contents of alcohol, total acidity, dry extract, total polyphenols, total and ftee anthocyanins, catechins and proanthocyanidins. They also were the most coloured, the reddest and darkest wines and those with the highest proportions of ionised anthocyanins and the most polymerised and condensed tannins. The average anthocyanic profiles of the wines of the three varieties were similar to those obtained in the respective skin extracts. Tannat grapes and wines had the highest non-acylated glucosides, petunidin and delphinidin proportions; Cabernet-Sauvignon presented the highest acetylated glucosides and malvidin proportions, whereas Meriot presented the highest coumarylic glucosides and peonidin proportions. Lyre conduction in Meriot allowed to obtain the highest yields and the grapes with the highest sugar and anthocyanin contents. Consequently, wines of this variety conducted in lyre had the highest alcohol, polyphenols and anthocyanins contents than those ftom trellis. Ln aIl the situations studied, the "year" effect was very significant, especially in relation to the polyphenolic composition of grapes and wines of the three varieties. The definition of the duration of the maceration for each variety, on the basis of the indices determined for the grapes in the maturity, the assays in the laboratory and the follow up of the polyphenols extractions in the vinification, allowed to establish extremely high correlations between the polyphenolic potential of the grapes and the colour and the phenolic composition of the wine. The knowledge of the anthocyanic and tannins richness of the grapes and its extractability allow to improve the management of the vinification and the prediction of some of the wines characteristics, such as its colour and phenolic composition

Full textThe growth of grapevine berries and their water and carbon supply are studied on fruiting cuttings under controlled conditions. Fluorescent probes were used to follow xylem and phloem transport to the berry. During the first growth period, there is a symplastic continuity between the mesocarp cells and the sieve tubes of the peripherie vascular network. At the onset of ripening, the circulation of the fluorescent probes stops in the tracheids and in the sieve tubes of the peripherie network. During ripening a symplastic discontinuity between the vascular bundles and the mesocarp cells could occur. The analysis of berry growth reveals two growth periods. During the first one, the berry is characterized by high transpiration and respiration rates and by water imports mainly through the xylem pathway. The seeds store half of the carbon accumulated in the whole berry. Organic acids represent 20 % of the carbon in the pericarp. At the beginning of the second period, berry growth resumes rapidly. Metabolic changes occur suddenly. Transpiration rates are much lower. Water is imported through the phloem pathway. Consequently carbon and mineraI nutrient imports are stimulated. Hexoses account for at least 40 % of the carbon stored in the pericarp. Respiration rates are reduced. During the first period, berry growth is very sensitive to a reduction in leaf area. Malic acid accumulation is affected. The onset of ripening is also delayed. There is no effect of this early limitation on berry growth and sugar accumulation during ripening if carbon supply is restored at veraison. On the contrary, a limited carbon supply during ripening does not reduce the fresh weight increase, but strongly affects sugar accumulation. During the first period, berry growth is under the control of source activity. During maturation, the regulation of imports to support growth occurs mainly in the berry

Full textMicrobial population of grapes is important from a technological point of view because it determines the quality of wine. But few studies have focused on fungal populations of grapes. A better knowledge of the fungal diversity on grapes, particularly as concerns species responsible for wine defects, may help efforts to control their development.We report the development of a PCR ITS-RFLP method as a fast and easy technique for identifying species of fungal genera present on grapes. By this methode, 41 different fungal species among 43 studied species belonging to 11 genera were characterized at the species level. Only P. thomii remained indistinguishable from P. glabrum. Using this PCR-ITS-RFLP, 96.3% strains tested could be differentiated to the species level with only four enzymes and 41.5% only with two enzymes. Moreover this work has contributed to the enriching of the database of fungal ITS sequences.Thus 199 isolated strain were on grapes in Burgundy vineyard were chacacterized at species level indepdantly of the genus by this method. P. spinolusum was the most frequently isolated species of Penicillium in Burgundy for 2008 vintage. Paralelly, the quantification of Botrytis cinerea, used as model, was developped by qPCR. The assay contained an internal amplification control to compensate for variations in DNA extraction and the various compounds from grapes, had high efficiency and the limit of detection was estimated to be 6.3 pg DNA (corresponding to 540 spores). This method was applied to assess the effects of various treatment strategies against Botrytis in the vineyard and demonstrates the importance of the prophylactic method

Full textThe wine-producing sector, notably in region Languedoc-Roussillon, is touched by the Ochratoxine A problem. Ochratoxine A is a fungal toxin with nephrotoxic, neurotoxic, carcinogenic and teratogenic effects. The wine is considered as the second cause in the ingestion of this toxin in the food behind cereal. Therefore, the European rule fixed the maximal limit of OTA content of wines and juice to 2 µg/Kg. The production of toxin is due to contamination of the grape by fungal strains of Aspergillus section Nigri. To help to fight against this problem, the fungal biodiversity of grapes and the toxigenesis of contaminants identified as well as the content in toxin of grape juices were characterized and followed for 4 years of harvest, on various geographical zones, various grape varieties and according to the treatment of the vine. A natural active treatment as stimulating of the defences was compared with a chemical treatment to assure the sanitary protection of the grape and the wine against the fungal ochratoxigenic contaminants. The main results allowed to show an important diversity of fungal strains according to grape variety, the treatment, the geographical region and the year of harvest. The use of the biological treatment leads to a maximal reduction from 50 to 80 % of the rate of OTA on 60 % of the samples of grape juices and wines. To understand and explain mechanisms involved in the action of the alternate treatments, the analyses of composition of grapes and volatile compounds of leaves were realized. The production of leaves and fruits can, indeed, be modified by stimulation of the natural defences and can lead to the production of factors of selection or inhibition of the fungal growth or the toxigenesis. The obtained preliminary results let see that there is, indeed, an action at the level of grapes treated biologically which have more thick skins and contents in acids different from grapes treated chemically, what could hamper the penetration of moulds in berries and interfere with their toxigenesis. Furthermore, differences of composition and content in volatile compounds of leaves stemming from 2 types of treatment are observed, with notably contents in aldehydes more raised after stimulation of the defences of the plant. Some of these compounds could have an antifungal action being translated by a decrease of the growth and the toxigenesis of ochratoxigenic contaminants

Full textThe total surface of vineyards worldwide is about 7.9 millions ha, which corresponds to an annual production of 67 millions tons berries. The annual world production of wines is about 300 millions hl/year. The French wineyard occupies 843 000 ha, among which 481 000 ha are dedicated to high quality wines (VQPRD) and 362 000 ha to table wines. Modern viticulture must deal with three major and related challenges : reduce the use of organic and inorganic phytochemicals, adapt the vineyard to climatic change and control the quality and the typicity in order to keep or gain new markets.In 2007, the grapevine became the first perennial fruit species whose genome was sequenced. This scientific breakthrough opens new pespectives in terms of functional genomics (set of methods allowing to characterize the function of genes) and integrative biology (set of methods allowing to study the global functioning of the plant and its response to the environment). These perspectives mainly depend on our ability to analyze large sets of data with adequate informatic tools.Functional approaches on candidate genes, and high throughput transcriptomic approaches have allowed to identify some genes or some gene families involved in the development and ripening of the grape berry, but when this Ph. D work started, no paper based on integrative biology was published on grapevine. The present work, which describes the collection and analysis of transcriptomic and metabolomic metadata related to the response of the berry to sun exposure. The exposure of the berries to the sun was controlled through a partial defoliation after veraison. This allowed to study the effects of sun exposure (exposed or shaded berries), of the position of the cluster (east, west) and of the anatomical position of the berry (outside or inside the berry). Berries were collected at 5 different time points after defoliation and used for metabolomic and transcriptomic analysis. Their content in sugars, amino acids, organic acids, anthocyanins and flavonols was analyzed by enzymatic assays and high performance liquid chromatography. For the berries whose metabolic content differed the most (exposed, west and outside berries vs shaded, east and inside berries), gene expression was studied with microarrays bearing a set of probes covering the whole genome of grapevine (29600 genes). Correlative and statistical analysis were conducted in order to (a) determine the metabolites that are the most responsive to the treatment, and the most important factors that control them (b) determine the genes that respond to the treatment and seem to be co-regulated (c) to precise the networks of genes and metabolites which seem related. Defoliation does not affect the sugar and tartaric acid contents, hardly affects amino acids, but it increases flavonol content and decreases malic acid content. It affects more specifically genes associated with abiotic stress, secondary metabolism, transport and hormonal metabolism. Additional experiments allowed us to identify genes that are specifically associated with the thermal component of sun exposure, among which genes encoding HSP, ABC transporters, and enzymes of flavonoid metabolism. Networks relating genes and metabolites could be constructed. These networks associate secondary metabolites with genes of known function and new candidate genes for which the function will have to be precised

La necesidad de aumentar la capacidad instalada de la matriz energética del país es un tema que en la última década se ha instalado en la agenda nacional, dado que el crecimiento económico de Chile implica un mayor consumo eléctrico. A su vez, la estrechez energética se ve representada con mayor profundidad en la industria de la minería, especialmente en el norte grande de Chile. El sector minero, además de ser el principal consumidor de energía eléctrica del país, ha experimentado desde el año 2000 una caída sostenida en su productividad, entre otros factores, por los mayores consumos y costos de la energía eléctrica, enfrentando actualmente uno de los precios más altos de América Latina1. Dado lo anterior, el Gobierno está asumiendo un rol más activo, definiendo una Agenda de Energía que incluye como uno de sus ejes el compromiso que un 45% de la capacidad eléctrica que se instalará en el país hasta el año 2025 sean energías renovables no convencionales (ERNC) y, de esta forma, cumplir con la meta de la Ley 20/25 de ingresar a la matriz energética un 20% de ERNC para dicho año. En este sentido, la energía fotovoltaica es una alternativa técnicamente viable para cubrir el consumo eléctrico, principalmente en el norte grande del país, dado que posee un importantísimo potencial solar. El propósito del presente plan de negocios es evaluar la factibilidad económica y financiera de ingresar al negocio de las energías renovables no convencionales, de una manera no convencional. Más allá de este juego de palabras, dado que la mayoría de los proyectos de generación de energía limpia se basan en el modelo de negocios tradicional, o sea generando e inyectando energía al sistema y transando los precios en el mercado spot, la oportunidad de negocio se visualiza en vender directamente la energía a la industria minera, sin intermediarios ni costos de transmisión relevantes. La industria eléctrica nacional está dividida en tres segmentos: generación, transmisión y distribución de energía eléctrica. Las actividades de transmisión y distribución tienen el carácter de monopolio natural. El sector de generación opera en condiciones de competencia, no obstante se caracteriza por ser un mercado altamente concentrado. Asimismo, existen cuatro sistemas eléctricos siendo los dos más importantes el SING (Sistema Interconectado del Norte Grande) y el SIC (Sistema Interconectado Central). La matriz energética del SING se alimenta en un 95% de fuentes térmicas (carbón, diésel, gas natural). En cuanto al desarrollo de proyectos ERNC, a pesar que el país posee condiciones naturales favorables para las energías solar y eólica, recién en el año 2014 se observó un “despegue” de las ERNC en Chile, materializándose proyectos con una capacidad instalada de casi 1.000 MW. Además, a nivel mundial la curva de aprendizaje en el costo de fabricación y operación de la tecnología solar fotovoltaica, ha permitido alcanzar precios competitivos respecto a las fuentes convencionales de energía. El mercado objetivo se concentra en el segmento de generación, a través del suministro eléctrico en base a energías renovables no convencionales, específicamente solar tipo fotovoltaica, para las empresas mineras (cobre) ubicadas en las regiones de Tarapacá y Antofagasta, ya que reúnen las condiciones de vida útil de la faena minera y disponibilidad de terrenos, de acuerdo a la propuesta de valor del proyecto. El modelo de negocios consiste en satisfacer parte de la demanda de energía eléctrica de las empresas mineras señaladas en el párrafo anterior, por medio de una planta solar fotovoltaica de 3 MW de potencia instalada y a través de un contrato de suministro tipo PPA (Power Purchase Agreement) a 20 años. La ventaja competitiva consiste en ofrecer una tarifa estable durante el período del contrato más baja que su tarifa actual en base a generación convencional, lo cual permitirá al cliente capturar y proyectar el ahorro en sus costos operativos. Además, la propuesta tiene la característica que la planta se construirá in-situ, aprovechando la superficie disponible en la faena minera, generando valor compartido en la economía de escala por el costo del terreno y línea de transmisión y conexión eléctrica. La operación y mantenimiento de la planta fotovoltaica estará a cargo de nuestra empresa. Para el desarrollo del negocio, dado que implica montos de inversión relevantes (USD 5,6 millones para cada planta) y se requiere de un respaldo tecnológico y logístico para realizar ese tipo de proyectos, se creará una Unidad Estratégica de Negocio (UEN) denominada “SUN POWER ENERGY” (SPE), bajo la estructura organizacional de E.CL S.A., una de las empresas principales que operan en el SING. Finalmente, en la evaluación financiera se contempla la ejecución de tres plantas solares dentro de los primeros seis años, con un total de aporte de capital requerido de USD 10 millones. Se ha considerado el apalancamiento financiero del proyecto, mediante la obtención de préstamos bancarios por USD 7,8 millones. Como resultado, través del valor actual de los flujos de caja libres descontados a una tasa del 7,5%, se obtiene un valor de la empresa sin deuda de USD 52.382, con una TIR del 7,5% y un periodo de recuperación de la inversión (payback) de 12 años. La TIR del inversionista alcanza al 7,9% con un VAN ajustado de USD 576.161.

Full textIn recent years there has been a significant increase in interest in smaller satellites as lower cost alternatives to traditional satellites, particularly with the rise in popularity of the CubeSat. Due to stringent mass, size, and often budget constraints, these small satellites rely on making the most of inexpensive hardware components and sensors, such as coarse sun sensors (CSS) and magnetometers. More expensive high-accuracy sun sensors often combine multiple measurements, and use specialized electronics, to deterministically solve for the direction of the Sun. Alternatively, cosine-type CSS output a voltage relative to the input light and are attractive due to their very low cost, simplicity to manufacture, small size, and minimal power consumption. This research investigates using coarse sun sensors for performing robust attitude estimation in order to point a spacecraft at the Sun after deployment from a launch vehicle, or following a system fault. As an alternative to using a large number of sensors, this thesis explores sun-direction estimation techniques with low computational costs that function well with underdetermined sets of CSS. Single-point estimators are coupled with simultaneous nonlinear control to achieve sun-pointing within a small percentage of a single orbit despite the partially underdetermined nature of the sensor suite. Leveraging an extensive analysis of the sensor models involved, sequential filtering techniques are shown to be capable of estimating the sun-direction to within a few degrees, with no a priori attitude information and using only CSS, despite the significant noise and biases present in the system. Detailed numerical simulations are used to compare and contrast the performance of the five different estimation techniques, with and without rate gyro measurements, their sensitivity to rate gyro accuracy, and their computation time. One of the key concerns with reducing the number of CSS is sensor degradation and failure. In this thesis, a Modified Rodrigues Parameter based CSS calibration filter suitable for autonomous on-board operation is developed. The sensitivity of this method's accuracy to the available Earth albedo data is evaluated and compared to the required computational effort. The calibration filter is expanded to perform sensor fault detection, and promising results are shown for reduced resolution albedo models. All of the methods discussed provide alternative attitude, determination, and control system algorithms for small satellite missions looking to use inexpensive, small sensors due to size, power, or budget limitations.

Full textThe effects of different anthropogenic activities (vineyard, winery) on fungal populations from grape to wine were studied. To characterize these effects, it was necessary to access to the overall diversity of populations (pyrosequencing and spectroscopy FT-IR) but also to intra-specific diversity (FT-IR). Spectroscopy FT-IR has been validated for their ability to characterize the global population and to discriminate the strains for three species of non-Saccharomyces yeasts (NS). For the first time, it is shown that the grape berry is a limited source for NS yeasts while the winery seems to be a significant source; the air is an important vector for dissemination of these yeasts. In addition, persistence of NS yeast strains from year to year in the winery has been demonstrated. The studied anthropogenic activities modify the fungal diversity. Thus, lower biodiversity of grapes from organic modality was measured for the three vintages considered. The pressing / clarification step revises strongly fungal populations and the influence of the winery flora is confirmed. The addition of SO2 changes the population dynamics and favors the dominance of the species S. cerevisiae. The non-targeted chemical analysis shows, for the first time, that these wines can be distinguished at the end of the alcoholic fermentation (with or without SO2) depending on plant protection. Thus, the existence in wines of chemical and microbiological signatures associated with vineyard protection mode is highlighted

Full textAn analysis of an existing building is performed, with an eye to its strengths and weaknesses as a residence. It is an interesting challenge for an architect to take an undistinguished building - one designed for a bygone age of surplus energy - to identify those substantive elements to be retained and reused, those which are to be eliminated or substantially altered, and then harmonize them, in conjunction with a new plan, in order to create a warm, energy efficient, aesthetically appealing, and ultimately livable family residence. The possibilities concerning the highest and best changes to be made to improve the use of an existing structure are first identified.
This thesis shows how a physically and spiritually cold, unattractive, and unremarkable building, one of little or no architectural merit, can be transformed - through improved natural light and heat - to create a better environment for a family.
