abstract: This dissertation presents research findings regarding the exploitation of localized surface plasmon (LSP) of epitaxial Ag islands as a means to enhance the photoluminescence (PL) of Germanium (Ge) quantum dots (QDs). The first step of this project was to investigate the growth of Ag islands on Si(100). Two distinct families of Ag islands have been observed. “Big islands” are clearly faceted and have basal dimensions in the few hundred nm to μm range with a variety of basal shapes. “Small islands” are not clearly faceted and have basal diameters in the 10s of nm range. Big islands form via a nucleation and growth mechanism, and small islands form via precipitation of Ag contained in a planar layer between the big islands that is thicker than the Stranski-Krastanov layer existing at room-temperature. The pseudodielectric functions of epitaxial Ag islands on Si(100) substrates were investigated with spectroscopic ellipsometry. Comparing the experimental pseudodielectric functions obtained for Si with and without Ag islands clearly identifies a plasmon mode with its dipole moment perpendicular to the surface. This observation is confirmed using a simulation based on the thin island film (TIF) theory. Another mode parallel to the surface may be identified by comparing the experimental pseudodielectric functions with the simulated ones from TIF theory. Additional results suggest that the LSP energy of Ag islands can be tuned from the ultra-violet to the infrared range by an amorphous Si (α-Si) cap layer. Heterostructures were grown that incorporated Ge QDs, an epitaxial Si cap layer and Ag islands grown atop the Si cap layer. Optimum growth conditions for distinct Ge dot ensembles and Si cap layers were obtained. The density of Ag islands grown on the Si cap layer depends on its thickness. Factors contributing to this effect may include the average strain and Ge concentration on the surface of the Si cap layer. The effects of the Ag LSP on the PL of Ge coherent domes were investigated for both α-Si capped and bare Ag islands. For samples with low-doped substrates, the LSPs reduce the Ge dot-related PL when the Si cap layer is below some critical thickness and have no effect on the PL when the Si cap layer is above the critical thickness. For samples grown on highly-doped wafers, the LSP of bare Ag islands enhanced the PL of Ge QDs by ~ 40%. / Dissertation/Thesis / Doctoral Dissertation Physics 2015

L'apparition des Systèmes d'Information ubiquitaires ou pervasifs est issue de l'émergence de nouvelles technologies fournissant au système une vision de son environnement, de l'environnement de ses utilisateurs ainsi que de leurs profils. Grâce à ces données formant le contexte de l'application, il est possible de fournir des services personnalisés, pertinents et ciblés. Mais, le problème qui se pose à ce niveau concerne le degré d'adaptation, de prise de décision à la place de l'utilisateur et de l'identification des données contextuelles nécessaires et suffisantes pour ces services. Ceci est dû à un déséquilibre entre les avancées des technologies et de leurs applications (qui reçoivent un grand intérêt de la part de la recherche et de l'industrie) et les méthodes et démarches de développement et d'ingénierie spécifiques aux systèmes ubiquitaires. Notre objectif dans ce travail de thèse est de proposer une méthode d'ingénierie des SI ubiquitaires en considérant les différentes exigences reliées à la nature mobile et grande échelle de ces systèmes. Cette méthode est basée sur une démarche de développement qui fait usage d'un ensemble de métamodèles et de langages génériques favorisant la spécification complète de ces systèmes. Cette démarche sépare les spécifications fonctionnelles, techniques et ubiquitaires. Les spécifications ubiquitaires permettent de définir des modèles structurels et événementiels du contexte respectant les exigences des utilisateurs et les contraintes de sécurité et supportant les fonctionnalités d'adaptation et de sensibilité au contexte. Cette approche orientée évènements est consolidée par l'adoption d'une architecture de traitement des évènements. Notre démarche E-CARe est une intégration des spécifications ubiquitaires dans une démarche classique de conception des SI pour garantir la couverture des spécifications fonctionnelles et techniques. Les applications d'assistance représentent un cas d'étude idéal pour cette démarche qui s'intéresse au domaine des transports, fortement dépendant de l'environnement et des évènements ambiants. / Ubiquitous Information Systems appeared as a consequence to emerging and evolving communication and mobile technologies providing the system with information on its environment, the environment of its users and their profiles. These data constitute the application context and are used to provide personalized, targeted and relevant services. However, ubiquitous services face some difficulties and challenges concerning specially needed contextual data, adaptation degree and computerized decision making. This is due to the gap between advanced ubiquitous services and their applications, and methods and processes for developing and engineering ubiquitous systems. Our goal in this thesis is to propose an engineering method for ubiquitous Information Systems considering different requirements resulting from the mobile and high scalable nature of these systems. The proposed method is based on a development process and a set of generic metamodels and languages facilitating a complete system specification and implementation. The proposed process separates functional, technical and ubiquitous specifications. Ubiquitous specifications enable the structural and event based context models definition while considering user requirements and security requirements. Adaptation and context awareness functionalities are supported by structural and dynamic context models. The proposed event oriented approach is enhanced by the adoption of an event processing architecture. Ubiquitous specifications are integrated into a classical information systems engineering process to constitute the E-CARe process including functional and technical specifications. Our propositions are used to design a user assistance application in the transport domain, highly dependent on the ambient environment and events.

Entretanto, considerando o elevado grau de intemperização em que se encontram os solos tropicais, os teores de silício disponíveis nestes solos são baixos. Nesse contexto o objetivo deste trabalho foi avaliar, em cana-de-açúcar sob condição de casa de vegetação, a escória de siderurgia como corretivo da acidez do solo e como fonte de silício e a sua interação com a adubação nitrogenada na produção de matéria seca, no teor de N e nos teores de silício no solo. Os tratamentos foram constituídos por duas fontes de corretivos (calcário e escória de siderurgia) em três doses (a metade, uma vez e duas vezes a dose recomendada), duas doses de N (uma vez e duas vezes a dose indicada), um tratamento controle (sem corretivo e sem nitrogênio). O delineamento experimental utilizado foi inteiramente casualizado com esquema fatorial 2x3x2 +1, com quatro repetições. A matéria seca, a altura de plantas e o ângulo foliar não foram influenciados pelas doses de N. Houve interação C X N, para matéria seca, N na planta, Si na planta e no solo e altura da planta. / The mineral fertilization is an important factor in enhancing the productivity of sugar cane. Among the essential nutrients, the nitrogen (N) is highlighted by the amount absorbed and removed. It should also give importance to the elements called non-essential, such as silicon (Si), which is supposed to increase production of sugar cane, specially under high doses of N. The Si content of tropical soils, however, is very low due to the advanced weathering degree. The objective of this work was to evaluate the growth of sucar cane in greenhouse conditions and the effects of nitrogen (N) and silicon (Si) doses on dry matter production, N content; Si soil and plant contents. The experimental design was a randomized blocks with treatments organized in 2x3x2+1 in factorial scheme ( two types of corrective material, tree corrective material rates, two nitrogen rates plus o control treatment), with four replications. The experimental units were pots filled with 40 dm3 of medium texture Oxissol. The slag improved soil concentrations of Si as well as its plant contents. Under recommended doses, the slag do not differ from lime on the leaves angle, and plant hight and dry matter. Levels of N alone do not affect the measured plant variables. However, the increasing on N levels reduced Si availability in the soil, but increased Si levels in the plant.

For a successful infection, these viral proteins must interact with host factors, modulating metabolic pathways and coordinating a complex network of biochemical and molecular interactions in the pathogen s favor. A subtractive library constructed from susceptible tomato plants infected by the plant potyvirus Pepper yellow mosaic virus (PepYMV) identified several genes which are putatively involved in the initial steps of the viral infection process, including those that code for the Translationally Controlled Tumor Protein (TCTP) and the tomato homologue of the Saccharomyces cerevisae Gal83 (Sl-Gal83), a protein of the SNF1 complex. TCTP is a highly conserved protein in eukaryotes, and is involved in several fundamental cellular processes such as cell growth, cell cycle progression, programmed cell death and protection against different types of stresses. SNF1 plays an important role in transcriptional activation and expression of genes involved in the cellular response to different stresses, such as nutrient limitation, high salinity, heat shock and virus infection. The objectives of this work were to study the roles of TCTP and Sl-Gal83 during PepYMV infection in susceptible hosts. Transgenic tomatoes (cv. 'Moneymaker') silenced for these genes were generated and were mechanically inoculated with PepYMV. ELISA and qRT-PCR were performed to verify the phenotype resulting from Sl-Gal83 and TCTP silencing. The results showed that non-transformed plants were infected, while all ten silenced plants remained symptomless, were ELISA negative and had reduced viral load. The subcellular localization of TCTP in healthy and PepYMVinfected plants was analyzed by confocal microscopy using a TCTP-YFP fusion. In healthy plants the subcellular localization of TCTP is cytoplasmatic, as described for other organisms. Forty-eight hours after PepYMV infection, TCTP is relocated to the nucleus. To determine which PepYMV protein(s) promotes nuclear targeting of TCTP, each viral protein (P1, HC-Pro, P3, PIPO, P3N-PIPO, CI, 6K2, NIa, NIb and CP) was coexpressed individually with pYFP-TCTP. Results showed that TCTP accumulates predominantly in the nucleus when co-infiltrated with CI and NIa, and is distributed equally in the nucleus and cytoplasm when co-infiltrated with P1, PIPO, P3N-PIPO, 6K2 and NIb. In plants co-infiltrated with HC-Pro, P3 and CP, TCTP remained in the cytoplasm. In order to identify and characterize additional viral and host factors involved in the TCTP-mediated network of plant-potyvirus interactions, TCTP was cloned as a TAP (tandem affinity purification) tag fusion.Protein complexes were purified using TAP, and its constituents were analyzed by mass spectrometry. However,it was not possible to identify the proteins. The probable limiting factor for a more efficient detection was the low concentration of protein eluted. Thus, it is necessary to optimize the protocol of extraction/elution to obtain a higher concentration of proteins complexed with nTAPi- TCTP. Together, the results of this work indicate that both TCTP and Sl-Gal83 play critical roles in the tomato-PepYMV interaction, being necessary for the establishment of a systemic infection. Further studies should be conducted to improve our understanding of the nature and mechanisms of the interactions between TCTP, Sl-Gal83 and PepYMV. / O genoma da maioria dos vírus que infectam plantas codifica apenas 4-10 proteínas, que são necessárias para completar o ciclo de infecção, incluindo as etapas de replicação do genoma viral, movimento célula-a-célula e movimento sistêmico. Para uma infecção bem sucedida, as proteínas virais devem interagir com fatores do hospedeiro, modulando processos metabólicos e coordenando uma rede complexa de interações bioquímicas e moleculares a favor do patógeno. Uma biblioteca subtrativa foi construída a partir de plantas de tomateiro suscetíveis infectadas pelo potyvírus Pepper yellow mosaic virus (PepYMV). Foram identificados vários genes potencialmente envolvidos nas etapas iniciais do processo de infecção viral. Dentre os genes identificados encontram-se os genes que codificam as proteínas Translationally controlled tumor protein (TCTP) e o homólogo de tomate de Saccharomyces cerevisae Gal83 (Sl-Gal83), uma proteína do complexo Sucrose non-fermenting-1 (SNF1). TCTP é uma proteína altamente conservada em eucariotos, e está envolvida em vários processos celulares básicos, como crescimento celular, progressão do ciclo celular, morte celular programada e proteção contra diversos tipos de estresses. SNF1 desempenha um papel importante na ativação da transcrição e expressão de genes envolvidos na resposta celular aos diferentes tipos de estresses, tais como limitação de nutrientes, salinidade elevada, choque térmico e infecção viral. O objetivo deste trabalho foi estudar o papel das proteínas TCTP e Sl-Gal83 durante o processo de infecção pelo PepYMV em hospedeiros suscetíveis. Plantas transgênicas de tomate cv. Moneymaker silenciadas para estes genes foram produzidas e inoculadas mecanicamente com o PepYMV. O estabelecimento da infecção viral foi avaliado por ELISA e qRT-PCR. Plantas não-transformadas foram infectadas, enquanto as plantas silenciadas permaneceram assintomáticas. Nas plantas silenciadas o ELISA apresentou resultado negativo e a carga viral foi reduzida. A localização subcelular de TCTP em plantas sadias e infectadas pelo PepYMV foi analisada por microscopia confocal utilizando-se uma fusão YFP-TCTP. Em plantas sadias a localização subcelular de TCTP é citoplasmática, conforme descrito para outros organismos. Quarenta e oito horas após a infecção pelo PepYMV, TCTP foi redirecionada para o núcleo. Para determinar qual é a proteína viral que direciona a relocalização de TCTP para o núcleo, cada uma das proteínas virais (P1, HC-Pro, P3, PIPO, P3N-PIPO, CI, 6K2, NIa, NIb e CP) foi coinfiltrada individualmente com pYFP-TCTP. Os resultados mostraram que TCTP acumula predominantemente no núcleo quando co-infiltrada com CI e NIa, e está igualmente distribuída no núcleo e citoplasma, quando co-infiltrada com P1, PIPO, P3NPIPO, 6K2 e NIb. Em plantas co-infiltradas com HC-Pro, P3 e CP, TCTP permaneceu no citoplasma. Para identificar possíveis proteínas virais e/ou do hospedeiro que interagem com TCTP foi realizado um ensaio de purificação por afinidade em tandem. A análise por SDS-PAGE de extratos protéicos de plantas expressando nTAPi-TCTP mostrou duas bandas entre 40 e 50 kDa presentes no extrato purificado. Os fragmentos foram analisados por espectrometria de massa, porém não foi possível identificar as proteínas. Provavelmente o limitante para uma detecção mais eficiente foi a baixa concentração de proteínas eluídas. Com isso, torna-se necessário a otimização do protocolo de extração/eluição para a obtenção de uma maior concentração de proteínas complexadas com nTAPi-TCTP. Em conjunto, os resultados obtidos neste trabalho sugerem que tanto TCTP quanto Sl-Gal83 possuem papéis fundamentais na interação PepYMV-tomate, sendo necessárias para o estabelecimento de uma infecção sistêmica. Estudos adicionais devem ser realizados para melhor compreensão da natureza e dos mecanismos das interações entre TCTP, Sl-Gal83 e o PepYMV.

Este é o resumo mais resumo dessa dissertação. Mas, pede a formalidade da linguagem acadêmica que o resumo seja mais amplo. Pois bem. Temos então: esta dissertação é a compreensão de alguns aspectos desencadeados por uma pesquisa, desenvolvida a partir da perspectiva sócio-histórica (FREITAS, 2003), junto a duas turmas de 8º ano do Ensino Fundamental de uma escola pública da rede estadual na cidade de Rio Claro/SP. Considerando quinze diários disponibilizados pelos autores-alunos, bem como os diários de campo da professora-pesquisadora e os post its que a mesma foi escrevendo ao longo da compreensão dos dados, por meio do paradigma indiciário de Ginzburg (1996), esta dissertação busca compreender a escrita de diários pessoais como forma de constituição dos sujeitos envolvidos na pesquisa, a partir das marcas de autoria que os mesmos instituíram no gênero discursivo diário pessoal. Na sequência, adentra a intimidade, pensada como amizade, enquanto aspecto inerente das relações estabelecidas entre os sujeitos na escrita dos diários pessoais, a fim de percebê-la como espaço da constituição do “eu” junto ao “outro”, bem como a relevância da responsabilidade ética das relações de intimidade estabelecidas na pesquisa com/na escola e, consequentemente, na/com a aula de Língua Portuguesa. Por fim, traz considerações acerca de “práticas outras” na aula de Língua Portuguesa, na pesquisa com/na escola e na escrita da dissertação. É preciso ressaltar também que esta dissertação é um feito-a-mão, uma feitura textual que busca a arte, por meio do processo de ficcionalização no gênero discursivo crônica, escolhido para compreender a autoria e a intimidade instituídas no gênero diário pessoal, bem como pelo tricotar, bordar, enfim, tecer um texto com as memórias que tenho da minha avó-artesã / A handmade of self-writing, authorship and intimacy from the writing of personal diaries in the Portuguese class. This is the smaller summary of this dissertation. But the formality of the academic language requires that the abstract be broader. Well. We have then: this dissertation is the understanding of some aspects triggered by a research, developed from the socio-historical perspective (FREITAS, 2003), together with two groups of 8th grade Elementary Public School in the city of Rio Claro, São Paulo State. Considering fifteen diaries made available by the author-students, as well as the field diaries of the teacher-researcher and the post-ones she has been writing along the data comprehension, through the Ginzburg (1996) indicium paradigm, this dissertation seeks to understand the writing of personal diaries as a form of constitution of the subjects involved in the research, based on the authorship marks that they instituted in the personal diary discursive genre. In the sequence, intimacy, thought as friendship, enters as an inherent aspect of the relations established between the subjects in the writing of the personal diaries, in order to perceive it as the space of the constitution of oneself next to the "other", as well as the relevance of the ethical responsibility of the relations of intimacy established in the research with / in the school and, consequently, in / with the Portuguese class. Finally, it brings considerations about "other practices" in the Portuguese class, in the research with / in the school and in the writing of the dissertation. It should also be pointed out that this dissertation is a handmade, textual work that seeks the art, through fictionalization process in the chronic discursive genre, chosen to understand the authorship and intimacy instituted in the personal diaries genre, as well as by knitting, embroidering, finally, weaving a text with the memories from of my grandmother-artisan.
