Cette thèse est la première monographie sur l’œuvre de l’écrivain et journaliste italien Nico Orengo (Turin, 1944-2009), auteur de recueils de poèmes, de récits et de romans, de comptines et récits pour enfants. Bien que la critique ait reconnu la valeur et l’intérêt de son œuvre et qu’elle ait présenté Orengo comme étant l’une des voix les plus originales de la littérature italienne contemporaine, aucun travail d’interprétation et d’approfondissement ne lui avait encore été consacré. Ce travail aspire à combler ce vide en démontrant qu’Orengo a été un précurseur eu égard tant aux sujets traités qu’aux modalités d’écriture choisies. Tous ses textes ont été étudiés à l’aune du paysage. L’intérêt de cette perspective relève de la place primordiale accordé dans son œuvre à un paysage bien défini et reconnaissable, celui de la Ligurie occidentale, à la frontière entre France et Italie, terre d’origine de sa famille. Cela nous a permis de vérifier comment l’auteur exploite la réalité du paysage, comment il l’exprime dans son écriture et quelles significations il lui attribue ; cela, dans but d’éclairer la nature de l’écriture d’un paysage. Sur le plan méthodologique nous nous appuyons sur la notion de paysage telle qu’elle a été élaborée par Michel Collot. L’approche thématique, alliée des outils d’analyse à disposition par la linguistique, la stylistique et la phénoménologie, est à la base de notre travail. / This thesis is the first monograph about the work of the Italian writer and journalist Nico Orengo (Turin, 1944-2009), the author of poetry collections, short stories and novels, nursery rhymes and children’s short stories. Even if critics have admitted the value and the interest of his work and despite portraying Orengo as one of the most original voices of contemporary Italian literature, not a single work of interpretation and analysis has yet to be written about him. This work aims to fill that void, showing that Orengo was a precursor for both the themes he approaches and the modalities of his writing style. All of his texts have been analysed through the landscape. The interest of this choice lies in the fact that Orengo, although a native of Turin, set almost all of his work in Liguria, focusing on a particularly defined and distinguishable landscape; the far west landscape, between France and Italy, the original region of his family. This allows us to show how Orengo uses this landscape reality, how he re-elaborates it in his writings and the meanings he gives to it, if he makes a coherent construction of it or, on the contrary, whether this construction changes over time and according to the genre of literature. The aim is to show what landscape writing consists of. Composed of three parts, this thesis is introduced by a preamble that defines the subject of this analysis, explaining the issues of research on the landscape in literature. On the methodological level, it is based on the perspective of landscape as proposed by Michel Collet and is inspired by his approach, appealing to thematic critics, but also to linguistics, stylistics and phenomenology.

The method is based on a cobalt phthalocyanine tetrasulfonate and 1-methyl-3-octylimidazolium tetrafluoroborate ionic liquidmodified nanotubes paste electrode. Images Scanning Electron Microscopy and Spectroscopy Fourier Transform Infrared were used to characterize the materials. The thiocholine oxidation process was investigated by cyclic voltammetry (CV) and chronoamperometry. The AChE enzyme was immobilized on the composite electrode surface by cross-linking with glutaraldehyde and chitosan. The synergistic action of NTCPM/CoTSPc/AChE showed excellent electrocatalytic activity with low applied potential for the detection of thiocholine. Parameters affecting the biosensor response such as enzyme loading, incubation time, pH and concentration of the buffer solution were optimized utilizing acetylthiocholine chloride (ATChCl) as substrate. The results showed that the fenitrothion, dichlorvos and malathion can lead to a reversible inhibition process of the enzyme. This biosensor showed low detection limit, good reproducibility, high stability and was used to determine pesticides in water samples. Linear relationships were found for fenitrothion (1.0-1000.0 pmol L-1), dichlorvos (2.0-8000.0 pmol L-1) and malathion (16.0-5000.0 pmol L-1. The biosensor has been successfully applied for river water samples and the results showed that there is no interference from the biological matrix. Recovery studies were performed to evaluate the accuracy of the method yielding a percentage of recovery between 99.12% and 103.05% for fenitrothion, 94.12% and 102.17% for dichlorvos and 100 03% and 100.96% for malathion.

Al?m disso, foram otimizadas as condi??es cromatogr?ficas por CLAE-UV para a an?lise destes compostos. O GLY foi selecionado para o estudo por ser um herbicida amplamente utilizado para o controle de pragas que, junto ao seu principal metab?lito secund?rio (AMPA) apresenta potencial risco toxicol?gico para a sa?de humana e para o meio ambiente. Devido aos seus efeitos delet?rios, alguns m?todos anal?ticos t?m sido desenvolvidos a fim de monitorar seus res?duos no meio ambiente. M?todos cromatogr?ficos t?m sido preferencialmente usados, contudo as mol?culas em estudo apresentam baixa volatilidade e aus?ncia de grupos crom?foros, sendo necess?rio adicionar etapas de derivatiza??o. Neste trabalho foram avaliadas duas metodologias para derivatiza??o das mol?culas de GLY e AMPA: com piririna e N-O(bistrimetilsilil)trifluoroacetamida (BSTFA) para an?lises por CG-EM e com cloroformiato de 9-fluorenilmetila (FMOC-Cl) para an?lises por CLAE-UV.

Finalmente, as condi??es ?timas de an?lise por CLAE-UV foram estudas e determinou-se que a fase m?vel composta por acetonitrila/tamp?o fosfato, comprimento de onda 260 nm, gradiente com propor??o de 25:75 v/v (0-2,5 minutos), 65:35 v/v (4,5-10 minutos) e 25:75 v/v (11-12 minutos) apresentaram melhores resultados. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Qu?mica, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2013. / ABSTRACT This study aimed to optimize both methodologies for derivatization of glyphosate (GLY) and aminomethylphosphonic acid (AMPA) for analysis by gas chromatography-mass spectrometry (GC-MS) and high performance liquid chromatography with ultraviolet detector (HPLC-UV). Moreover, the chromatographic conditions were optimized by HPLC-UV for the analysis of these compounds. The GLY was selected for the study because it is a herbicide widely used for pest control that, with its main secondary metabolite (AMPA) has potential toxicological risk to human health and the environment. Due to the deleterious effects, some analytical methods have been developed to monitor their residues on the environment. Chromatographic methods have been used preferentially, however the molecules in study have low volatility and absence of chromophoric groups being necessary to add derivatization steps. In this work were evaluated two methodologies for derivatization of GLY and AMPA molecules: pyridine and N-O(bistrimethylsilyl)trifluoroacetamide (BSTFA) for analysis by GC-MS and 9-fluorenylmethyl chloroformate (FMOC-Cl) for analysis by HPLC-UV. The use of pyridine:BSTFA in ratio 60:100, respectively, without ultrasonic vibration and adjustment pH result in better analyses conditions by GC-MS. Already for analysis by HPLC-UV, borate buffer 200 mmol L-1, FMOC-Cl 500 mg L-1, homogenization for 5 minutes, analysis immediately after reaction and washing with diethyl ether promoted satisfactory results. Finally, the optimal conditions for analysis by HPLC-UV were studied and it was determined that the mobile phase consisting of acetonitrile / phosphate buffer, wavelength 260 nm, ratio gradient 25:75 v / v (0-2.5 minutes ), 65:35 v / v (4.5-10 minutes), 25:75 v / v (11-12 minutes) showed better results.

Nowadays, it?s known how these forms of consumptions can contribute to the consumer?s well-being, either by conceiving episodic pleasures, or by leading to some personal growth. Despite a number of studies exploring how services and products can individually be a source of these experiences, little has been dedicated to comprehending how both a product and a service can be consumed at the same time and space. This restricted scope has limited the knowledge of some ?ornamented consumption?, on which, with the intention of live a richer experience, the consumer deliberately bring a complementary product to be consumed during a service. Willing to comprehend how the consumers can use such products to create symbiotic experiences with a service, and how these consumptions can benefit his or her well-being, the present dissertation explored the ?cosplay experience?. The cosplayers bring and wear their own cosplays at geek conventions, intentionally enriching their experiences inside these spaces by characterizing themselves as some fictional character from the geek culture, widening their range of interactions and activities during the con, such as posing to some photos or playing the character in an improvised scene in front of a crowd of other consumers. Through the observation of geek conventions and a series of videographic interviews with cosplayers, this study assessed how the cosplay can shift the way the consumer interpret the geek convention, becoming seemed as just a stage for the use of cosplays; with the cosplay being used both as a way to intensify the ludic and escapist aspects of the convention experience, and/or a form of self-expression and personal challenge, evoking multiple long term benefits to the consumer well-being, as self-comprehension, social skills and body acceptance. / Consumidores costumam comprar e consumir diversos produtos e servi?os na inten??o de viver experi?ncias l?dicas. Hoje em dia se compreende que tais formas de consumos possuem impactos sobre o bem-estar de uma pessoa, seja por conceder um prazer epis?dico, seja por contribuir para o crescimento pessoal do consumidor. Apesar de diversos estudos explorarem como um servi?o ou um produto em espec?fico podem ser fontes de experi?ncias que contribuem para o bem-estar, pouco se explorou como ambos podem ser consumidos em um mesmo espa?o e tempo. Este escopo restringido limita a compreens?o de consumos ornamentados, onde, com a inten??o de consumir uma experi?ncia mais rica, o consumidor leva um produto complementar para ser consumido durante um servi?o. Visando compreender como o consumidor pode usar estes produtos para criar esta experi?ncia simbi?tica com o servi?o, e como este consumo contribui para o seu bem-estar, a atual disserta??o explorou a experi?ncia cosplay. Os cosplayers levam e vestem os seus pr?prios cosplays nos eventos geek, intencionalmente enriquecendo as suas experi?ncias nestes espa?os ao se caracterizarem e interpretarem algum personagem fict?cio da cultura geek, ampliando o seu leque de intera??es e atividades no evento, como posar para fotos e realizar encena??es improvisadas em frente a uma plateia de outros consumidores. Atrav?s de observa??es participantes em eventos geek e entrevistas videogr?ficas com cosplayers, este estudo averiguou que o uso do cosplay altera a forma como o cosplayer interpreta o evento geek em geral, se tornando somente um palco para o uso do cosplay; com o cosplay podendo ser consumido tanto como uma forma de intensificar as atividades l?dicas e escapistas da experi?ncia no evento, quanto como um meio para express?o e desafio pessoal, gerando diferentes retornos a longo prazo, como autocompreens?o, habilidades sociais e aceita??o corporal.

The objective of this work was to analyze the strategies developed by the portals of Electronic Commerce in Brazil as for the use of search engines for the diffusion of the information and popularization. They were selected and analyzed the largest portals of Electronic Commerce of sale to the consumer in agreement with the ranking of the magazine Info Exame of May of 2003. The researched companies were selected and analyzed using an adaptation of the model of CZUCHRY (2002). it was made a quantitative study of cases in way to observe relevant characteristics for the success of companies of this type. The strategies used for each portal were analyzed in terms of products, services, payment conditions, association to mechanisms of searches and electronic shopping centers, delivery logistics and marketing actions and publicity. The action of each site of Electronic Commerce is linked to the objective of each company. Linked Sites to companies that act at the traditional market possess a form of acting different from sites that only act in the virtual world. These should be more efficient, because they cannot take advantage of of the coming savings of the existence of a structure logistics to assist the physical store. On the other hand, the existent stores only in the virtual world they possess the largest agility, exactly for they be not connected to a pr?-existent structure. The success in the electronic retail comes from the offer of quality products with a good price, associated the services rendered with high excellence level. To know to take advantage of the advantages of the Electronic Commerce is key so that one can obtain the largest volume of sales and possible profitability. It was possible to identify that, in general, the great portals of I Commerce Electronic they don't locate among the first ones put in the search mechanisms to the if he/she researches the products marketed by the largest Portals Brazilian B2C. Just some portals present a good collation in the mechanisms of search in solid and independent way of the researched product. These portals also present a good collation in the ranking of the magazine Info Exame, suggesting that a strategy of diffusion of information through search mechanisms can help to resulted best of those companies. On the other hand, the search mechanisms have been neglectful for a significant portion of the companies. The need exists of looking for insert strategies in these important tools of the net. The consumer can compare, through the internet, price and conditions, besides the characteristics of each product in a fast and efficient way. Portals that possess not a solid strategy of diffusion of information through search mechanism can lose sales in the measure in that the Internet and their tools become more and more popular. / A Tecnologia da Informa??o tem modificado a forma que as empresas operam e a maneira pela qual elas se relacionam com seus clientes e fornecedores.

3D VLSI with a CoolCube TM process allows vertically stacking several layers of devices with a unique connecting via density above a million/mm2. The thermal budget allowed to process the top transistor is currently limited by NiPt silicide stability of the bottom transistor. To extend the upper transistors thermal process window, Pre-Amorphization Implant (PAI) and Si-Capping were used to improve the stability of NiPt 15% on SiC:P and SiGe 30% :B accesses. While PAI enhances the silicide stability on SiC:P substrate from 600°C 2h to 700°C 2h, neither PAI nor Si-Capping improve silicide stability on SiGe 30% :B. To provide a solution for P accesses stability, NiCo 10% silicidation has been developed. Combined with PAI and Si-Capping, the germano-silicide offers a higher stability (up to 600°C 2h) than its NiPtSi 15% counterpart.

The single taxation model has stood out due to its apparent simplicity and economic efficiency, being considered as a solution to the current complex and costly tax structures. In this way, the feasibility of the single tax is questioned in the current legal systems. Through an instrumental bibliographical procedure, the deduction was used to answer such problematic. For that, a priori, the history of the single tax, from the first records in France and the studies of Physiocracy, to the current Brazilian debate on the single federal tax on financial transactions was reported. In the second moment, the proposal was evaluated under the prism of the main theories of the optimal taxation of Smith, Musgrave, Neumark and Stiglitz. Finally, the last chapter developed the contemporary debate on the single tax, explaining its advantages and disadvantages, and then concluding on its viability or not. / A presente Disserta????o tem o escopo de apresentar o instituto do imposto ??nico e analis??-lo ?? luz dos princ??pios da tributa????o ??tima.

No segundo momento, a proposta foi avaliada sob o prisma das principais teorias da tributa????o ??tima de Smith, Musgrave, Neumark e Stiglitz. Por fim, o ??ltimo cap??tulo desenvolveu o debate contempor??neo acerca do imposto ??nico, explicitando suas vantagens e desvantagens, para, ent??o, concluir sobre sua viabilidade ou n??o.

Seu uso indiscriminado tem frequentemente evidenciado rea??es indesej?veis nos usu?rios destes produtos. A literatura cient?fica dispon?vel n?o esclarece, de forma conclusiva, a etiologia dos efeitos adversos que podem ocorrer a partir da sua inje??o. A presente pesquisa teve por objetivo avaliar, por meio da an?lise cl?nica e histol?gica, a resposta tissular local e sist?mica de duas concentra??es de AH em l?ngua de ratos. Cinquenta e quatro ratos f?meos (Rattus norvegicus, Wistar) foram distribu?dos em 3 grupos de tratamento (AH 5,5mg/mL, AH 25mg/mL e NaCl 0,9 % - controle) e 3 tempos experimentais (7 dias, 60 dias e 90 dias). Antes da eutan?sia, procedeu-se a avalia??o cl?nica, atrav?s de par?metros de presen?a e aus?ncia de sinais. Posteriormente, removeu-se l?ngua e rim direito para an?lise microsc?pica. Nos cortes de l?ngua corados por hematoxilina e eosina (HE), mensurou-se par?metros de aus?ncia ou presen?a de rea??o inflamat?ria, sendo esta classificada como leve, moderada ou severa. Nos cortes corados com picros?rius, estabeleceuse o percentual de fibras col?genas presentes. Nas amostras obtidas do rim (HE), foram observadas a presen?a ou aus?ncia de resposta inflamat?ria em toda a extens?o da l?mina. As altera??es cl?nicas presentes n?o foram estatisticamente significativas entre os grupos (Kruskal-Wallis; p>0,05). Histologicamente, os grupos AH apresentaram maior grau de inflama??o que os controles em todos os tempos do experimento (Kruskal-Wallis, p< 0,01). Quanto ? fibroplasia, o grupo AH 25mg/mL tendeu a formar mais col?geno se comparado ao grupo controle (ANOVA Mixed Models; p=0.016). Em 100% das amostras de rim analisadas, n?o se observou resposta inflamat?ria. A partir da metodologia utilizada neste estudo, os resultados obtidos permitem concluir que (1) O AH nas concentra??es de 5,5 e 25mg/mL provocou altera??es cl?nicas vari?veis e ocasionais em todos os per?odos; (2) O AH nas Atr 14 concentra??es utilizadas, em at? 7 dias, promoveu um grau moderado de inflama??o tecidual; (3) A rea??o inflamat?ria circunjacente ?s part?culas do AH diminuiu de intensidade entre 60 e 90 dias, reduzindo a possibilidade de rea??es adversas pelo uso do material; (4) O AH 25mg/mL suscitou maior forma??o de col?geno se comparado ao grupo controle; (5) N?o houve resposta inflamat?ria e/ou migra??o sist?mica renal a partir da inje??o do AH a 5,5mg/mL e 25mg/mL em at? 90 dias de observa??o.

Memoria para optar al t?tulo de Ingeniero Civil Industrial / Cuponatic es una empresa de cupones de descuento online. Su modelo de negocios consiste en ser nexo entre locales comerciales y potenciales clientes a trav?s de su portal web www.cuponatic.com. Actualmente, un 16% de las entregas de productos sufre retrasos, de las cuales un 5% conllevaron a la devoluci?n del dinero a los clientes. A su vez, un 25,6% de las consultas recibidas por el Servicio al Cliente corresponden a reclamos por el retraso en la entrega de productos, de los cuales un 19,3% derivan en un reclamo formal contra la empresa. Se estima que la p?rdida de utilidades mensuales por aumento de costos de entrega y reembolsos asciende a m?s de $ 1.676.000, esto sin considerar el da?o a la imagen de Cuponatic y con ello menores ventas a futuro. El objetivo general del trabajo fue proponer un redise?o del proceso de entrega de productos a los clientes, para mejorar el nivel de calidad del servicio en cuanto al cumplimiento de los tiempos bajo las condiciones de despacho seleccionada por el comprador. Los objetivos espec?ficos fueron definir los procesos cr?ticos en la entrega de productos en conjunto con Cuponatic, realizar un diagn?stico de la situaci?n actual, proponer un redise?o sobre los procesos cr?ticos de la cadena de suministro y finalmente definir y mejorar los indicadores que apoyen y controlen el proceso. El marco conceptual utilizado es el de redise?o de procesos a trav?s de patrones del profesor Oscar Barros. La t?cnica para modelar los macro-procesos es la metodolog?a IDEF0, mientras que para modelar los procesos espec?ficos se us? la metodolog?a BPM. Del an?lisis de la situaci?n actual se concluy? que los clientes no est?n satisfechos con la actual gesti?n de la entrega de productos, en donde los procesos cr?ticos detectados que causan esta problem?tica son el env?o de productos entre bodega, el env?o de productos a Cuponatic por parte de sus proveedores y el despacho de productos a domicilio por parte de CorreosChile. Se observa que no existe coordinaci?n entre Cuponatic y sus proveedores, no se controla ni exige el cumplimiento de los plazos de entrega de los productos acordados entre ambos, en donde no son gestionados ni controlados los retrasos en los procesos de Log?stica. En base a lo anterior, las variables del redise?o principales son la coordinaci?n e integraci?n de los procesos conexos, desde la creaci?n de la oferta comercial hasta la entrega del producto al cliente. En espec?fico, se generan reportes que eval?en punto a punto el estado de entrega del producto, desde su recepci?n por Cuponatic del proveedor hasta la entrega final al cliente, unificando la informaci?n log?stica de CorreosChile y los proveedores en las plataformas tecnol?gicas de Cuponatic. Los reportes contienen indicadores de gesti?n que apoyan y controlan los procesos. Asimismo se definen responsables de la gesti?n a lo largo de la cadena de suministro. Gracias al redise?o propuesto ser? posible disminuir el incumplimiento de los proveedores en la entrega de productos a Cuponatic y as? mejorar los niveles de servicio a los clientes. A su vez, permite alinear a los responsables en la cadena de suministro al cumplimiento de las promesas de entrega y con ello realizar una gesti?n efectiva de toda la cadena.
