Maillot, Charlotte. "Quantification and impact of microcarrier collisions during mesenchymal stem cell culture in bioreactors." Electronic Thesis or Diss., Université de Lorraine, 2022. http://www.theses.fr/2022LORR0314.
To date, bottlenecks persist concerning deep scientific understanding of how various process parameters will impact the Mesenchymal Stem Cell production. Specifically applied to microcarrier-based expansion processes of WJ-MSC's, very little information is available to characterize the impact of microcarrier concentration on MSC growth and death rates or on critical quality attributes which may have crucial and possibly dangerous clinical impacts. As a result, the following work proposes to rationally describe the impact of particle concentration on MSC growth through a pluri-disciplinary characterization of microcarrier-microcarrier interactions in agitated conditions. In order to do so the biological and physical aspects of this work will be presented. To begin with, a quantitative approach to estimate cell growth and death kinetics caused by microcarrier-microcarrier collisions in both Erlenmeyer Flasks and Spinner Flasks is described. For this, cells were grown at various microcarrier concentrations using two microcarrier types : Cytodex-1 and Synthemax II. Complementary cultures were performed by adding various concentrations of particles with the same size and density as microcarriers in view of providing specific information on how additional particles may impact MSC growth on microcarriers. In addition, elements of MSC characterization were performed for these experiments to understand not only the impact of microcarrier-microcarrier interactions on growth but also on defined elements of cell quality. In parallel, in order to estimate the amount and intensity of microcarrier-microcarrier collisions in a specific tank geometry, experiments were performed using both the attenuation of light by Cytodex-1 microcarriers (to estimate local microcarrier concentration) and the acoustic signal which comes from particles colliding with a hydrophone (to estimate microcarrier-sensor collision frequency and intensity). These experiments provided elements to estimate the amount of particle collisions that MSC's may perceive during specific dynamic and steady phases of cell culture in STR's. Lastly, a bioreactor-based approach to MSC manufacturing will be presented focusing on biological aspects of how particle concentration and agitation impacts MSC growth and quality attributes. For this, various MSC cultures were performed in STRs with varying particle concentrations and agitation strategies. The MSC's produced in these conditions were then characterized to define if certain critical quality attributes could be affected by parameters such as microcarrier concentration and/or agitation

Syftet: Vårt mål är att förstå hur multinationella företag integrerar kulturellt mångfald i deras företagskultur. För att uppnå detta mål jämför vi medarbetarnas uppfattning med företagets syn i ämnet. Design / metod / tillvägagångssätt: En kvalitativ fallstudie genomförs med tre uppsättningar av frågeformulär. Två av frågeformulären utformades för utländska och lokala anställda. Den tredje uppsättningen skapades för personalavdelningschefen som representerade företagets uppfattning. En analys görs genom att jämföra teorierna med det empiriska resultatet av studien. Resultat: Resultatet visade att företagskulturen är inspirerad av den nationella kulturen. Genom att implementera en organiserad rekryteringsprocess, socialisering och lagarbete, kan multinationella företagen integrera kulturell mångfald framgångsrikt i sin företagskultur. Flera verktyg så som att erbjuda språkkurser, utskick på bägge språken, ett välkomshäfte för det nya landet, mentorer, anonym feedback om kulturella frågor och sport eller kulturutflykter föreslås för att hantera kulturell mångfald. Dessa verktyg kan användas för både utländska och lokala anställda. Integrationen bygger på både de anställda och företaget. Högre befattningar bör dock stödja personalavdelningen för att hitta lösningar för integration av en multikulturell arbetskraft. Praktiska åtgärder: Samtidsstudier som verktyg så som mentorprogram är kostsamma och kan skapa fördomar samtidigt när man vill behandla ämnet. Den här studien föreslår verktyg som är kostnadseffektiva och funktionella för att integrera och hantera kulturella mångfald hos de anställda. Bidrag: Tidigare studier betonar inte företagskulturens roll i att integrera kulturell mångfald hos anställda. Denna studie fokuserar på det empiriska gapet av medarbetarnas uppfattning om företagskulturens roll för att integrera den kulturella mångfalden. Det föreslås, för att hantera kulturell mångfald bör företagen bara fokusera på den nationella kulturen och företagskulturen och inte nödvändigtvis på medarbetarens kultur.
Zomer, Helena Debiazi. "Estabelecimento de cultura de células de pluripotência induzida a partir de células tronco derivadas do tecido adiposo de coelhos." Universidade de São Paulo, 2013. http://www.teses.usp.br/teses/disponiveis/10/10132/tde-18072014-103412/.
Induced Pluripotent Stem (iPS) cells were first reported in 2006 by Takahashi e Yamanaka and has been intensively studied since then. Through the technique, adult somatic cells acquire behavior very similar to embryonic stem cells, reducing the ethical issues related to the use of such research. However, biological mechanisms of iPS cells are not yet fully elucidated. Thus, further research is needed to ensure the safety and efficacy for their possible use in future therapies. Rabbits, as experimental models, are advantageous by their ideal size for surgical procedures and easy and economic maintenance. Adipose Derived Stem Cells (ADSC) consists of multipotent mesenchymal stem cells that stand for ease, speed and safety of collection and processing. The ADSC were collected and characterized by analysis of cell growth curve, doubling time, viability after cryopreservation, ability of fibroblast colony formation, osteogenic, adipogenic and chondrogenic differentiation, immunocytochemistry and flow cytometry. They showed to have the basic characteristics of mesenchymal stem cells, standing out by a high and fast proliferative capacity. Induction of pluripotency was performed in rabbits ADSC by the introduction of four transcription factors (OCT4, SOX2, cMYC, and KLF4) by lentiviral vector STEMCCA (Millipore). Five protocols were tested and analyzed. The resulting cells after induction were characterized by alkaline phosphatase activity and phenotypic profile by flow cytometry. The great proliferation of ADSC seems to be detrimental for the reprogramming efficiency. From these data, it is expected to contribute to the development of a Brazilian technology still unpublished in rabbits, and to add important information to the literature about the properties of iPS cells, aiming their use as an experimental model for future therapies.

Resumo: Este texto analisa a formação de professores, realizada no âmbito das políticas públicas decorrentes dos acordos MEC/USAID/UNESCO, no pós Segunda Guerra Mundial, que resultaram na criação dos Centros de Formação de Professores Primários, entre 1961 e 1983, no município de Catalão, Goiás. Estes cursos de formação, de orientação tecnicista na educação, foram iniciados no Governo Mauro Borges após o Golpe Militar de 1964, com o intuito de planejar, racionalizar os investimentos no setor educacional. Os acordos firmados tinham como elemento chave a formação de uma sociedade "massificada" através da democratização da educação, de bens e de consumo para o mercado. O material didático utilizado nesse processo de formação era elaborado por equipes de trabalho orientadas e vinculadas ao Programa Brasileiro-Americano para o Ensino Primário (PABAEE). As especificidades desta formação, em tempo integral, em regime de internato, se propunha a melhorar a produtividade e a qualidade do ensino do 1º grau e Normal. As principais fontes primárias, inéditas, utilizadas nesta pesquisa foram localizadas no arquivo do Núcleo de Estudos e Pesquisas em Educação de Catalão (NEPEDUCA), da Universidade Federal de Goiás (UFG), Campus Catalão, onde pudemos ter acesso aos projetos para instalação dos Centros Experimentais de Formação de Professores, aos planos de cursos, planilhas, avaliações e textos produzidos pelos professores e bolsistas. A análise das referidas fontes evidenciaram conluio de interesses no período de internacionalização da economia brasileira, criando as condições materiais, técnicas e humanas para a execução dos acordos Brasil/USAID. A interpretação das fontes revelaram-nos que as teorias e metodologias usadas pelos Centro reproduzia uma orientação escolanovista, já ultrapassada nos Estados Unidos, mas que passa a ser usada durante a Ditadura Militar como mecanismo de controle social sem recorrer a violência explícita, pois aplicadas nas escolas, lócus de preservação e distribuição cultural. Os relatos dos bolsistas indicam que mudanças foram sutilmente introduzidas alterando seus valores, comportamentos e práticas pedagógicas, assim como sua percepção de escola, da cidade e das relações socioculturais e políticas engendradas entre as instâncias do poder constituído e a sociedade catalana. As representações construídas pelos bolsistas revelam que os conteúdos transmitidos foram assimilados e condicionaram sua percepção de mundo, de sociedade, e que para o bom funcionamento da cidade havia uma hierarquia entre poderes e posições sociais a ser respeitado, sem contestação e cabia ao indivíduo, agora identificado com os valores da pátria, assumir para si os encargos públicos antes atribuídos ao Estado.
Abstract: This text analyses the teacher training, carried out according to the public policies reached in MEC/USAID/UNESCO agreements, in the post Second World War, which resulted in the creation of Primary Teaching Training Centers, from 1961 to 1983, in Catalão, Goiás. These training courses, with technical orientation on education, started to run during Mauro Borges' Government after the Military Coup in 1964, in order to plan and rationalize the investments in education. The key element of the agreements signed, was the formation of a "mass" society through the democratization of education, of material goods and through the acquisition of things, the market. The material used in this teaching process was developed by teams which were orientated and linked to the Brazilian-American Program for the Primary Education (PABAEE). The specifics of this formation which took place in boarding schools in a full-time period aimed to improve the productivity and the quality of the Elementary School and the "Normal" School. The main primary sources used in this research were found in the files of the "Núcleo de Estudos e Pesquisas em Educação de Catalão (NEPEDUCA) (Study and Research Center for Education, in Catalão), located in the Federal University of Goiás (UFG), Catalão Campus, where it was allowed our access not only to the projects to set up the Experimental Centers for Teaching Training, but also to the lesson plans, worksheets, evaluations and texts created by teachers and scholars with a scholarship. The analysis of the aforementioned sources made it quite clear that during the period of internationalization of the Brazilian economy, the technical, human and material conditions were settled in order to reach Brazil / USAID agreement. The interpretation of the sources showed that the theories and methodologies used by the Centers reproduced a "escolanovista" orientation which wasn't popular in the United States anymore, but which started being used during Military Coup as a social control mechanism without the necessity to make use of explicit violence, as applied in schools, locus of cultural preservation and distribution. The scholars with a scholarship reported that changes were subtly introduced altering values, behaviors and pedagogical practices. Their perception of the school, of the city and of the political and socio-cultural relationships engendered between the power which was constituted and the Catalana society was also altered. The representations built by the scholars with a scholarship show that the contents taught were learnt and understood. Their perception of the world, and the society were conditioned and in order to make the city works and operates well there was an hierarchy of power and social positions to be respected, without any kind of objection, and the individuals, now identified according to the values of the homeland, had to take over public charges previously attributed to the State.

Neste trabalho, descreve-se e analisa-se o repertório de brinquedos e brincadeiras vivenciadas por crianças indígenas Pataxós (MG) e crianças moradoras do bairro Taquaril em Belo Horizonte. Interessou-nos compreender como crianças de diferentes contextos socioculturais experienciam a prática da brincadeira, suas dinâmicas e significados. Investigou-se, ainda, que elementos próprios da inserção sociocultural surgem nessa experiência, entendendo o brincar como forma própria de compreensão e apreensão do mundo pelas crianças. As principais referências teóricas deste trabalho são estudos contemporâneos dos campos da sociologia, antropologia e história da infância, voltados para o entendimento da criança como sujeito sócio-histórico e cultural, produtor de uma cultura singular, construída na interação com a cultura adulta. Com base na compreensão de cada contexto sociocultural no qual os diferentes grupos de crianças observados vivem, foi realizada uma investigação sociológica de quotidianos infantis para se apreender o repertório de práticas culturais de cada um dos grupos, suas interações e a produção de sentidos sobre o que fazem. Nesse exercício, assumem destaque os diferentes usos dos espaços e tempos do brincar em cada contexto e as relações estabelecidas com os adultos e elementos da cultura adulta na prática da brincadeira. Da análise das relações entre brincadeiras e brinquedos de diferentes contextos, da cartografia de similaridades, especificidades e, principalmente, da apreensão da dimensão cultural dessa prática, emergem características singulares, universais e sazonais que constituem esse repertório de brinquedos e brincadeiras. Revelam-se ainda, nessas práticas, as condições de se viver a infância, bem como traços indentitários e de pertencimento cultural de cada grupo. Nesse sentido, este trabalho, à medida que busca a compreensão do brincar como linguagem infantil que significa o mundo, contribui para a constituição de um modo de ver da criança em sua singularidade, suas formas de apreender e se relacionar com seus pares e seu entorno, mas, principalmente, para a elaboração das imagens construídas sobre as múltiplas infâncias na contemporaneidade.
Vermillac, Michel. "Mac Luhan et la modernité." Nice, 1993. http://www.theses.fr/1993NICE2021.
History of ideas works like a riddle : some authors are selected, some not. Thinking of this, Bateson talks about a real ecology of mind. Herbert Marshall Mac Luhan (1911-1980) was a living paradox : introducing modernity with his concept of marconi galaxy, he was ignored by french thinkers of the late sixties. Or, the same ideas will be taken again, without refering to him, by post modernity philosophers. What are the reasons of such a contempt ? Why an essayist as famous as Mac Luhan was not accepted by the french intelligentzia of 1968 ? Was he a prophet, when he was annoucing the future of technology ? Not with standing his attacks against rationality, mac luhan was an humanist, maybe a fideist : if it's difficult to build a clear vision of the world, because of the stength of illusion, relationship between men must give a meaning to modern life

O estudo teve como objetivo geral discutir a reapropriação do espaço público na cidade por grupos sociais e os fluxos informacionais criados a partir da interação entre eles. Nos últimos anos, a ênfase no viés econômico por parte do Estado vem trazendo restrições a moradores e frequentadores no uso dos lugares da vida cotidiana pública. A liberdade de circulação esbarra em iniciativas de privatização de locais antes destinados ao encontro de pessoas e a outras experiências coletivas. A pesquisa, de caráter qualitativo, teve como objeto de análise empírica o Duelo de MCs, movimento hip-hop que ocupa, nas noites de sexta-feira, a área sob o Viaduto Santa Tereza, no Centro de Belo Horizonte, e reúne jovens, na sua maioria negros, com diversos níveis socioculturais e de diferentes regiões da capital mineira para batalhas entre MCs, a partir da improvisação de rimas e ao som do rap. A fundamentação teórica pautou-se pela discussão das culturas pós-modernas e a conceituação de público, cidade informacional, direito à cidade, cidadania cultural e informação enquanto fenômeno social. Além disso, apresentou-se um breve histórico dos últimos movimentos de ocupação das cidades no Brasil e no mundo. A metodologia contemplou o trabalho de campo, com o acompanhamento do Duelo de MCs entre agosto e dezembro de 2012; entrevistas com organizadores do movimento; análise de conteúdo dos versos das batalhas do conhecimento uma das modalidades do Duelo de MCs que sugere um tema antes das disputas , bem como de letras de música, cartazes e graffitis presentes sob o viaduto e panfletos e fanzine distribuídos; entrevistas estruturadas com o público e netnografia dos organizadores e seus seguidores nas redes sociais digitais. Concluiu-se que as trocas informacionais entre esses jovens revelam, no Centro da cidade, uma cultura emergente, cujo repertório ficava restrito a zonas periféricas, como favelas e aglomerados. Além disso, elas possibilitam a construção de novas representações simbólicas e de um espaço de pertença coletiva e resistência cultural da juventude negra periférica em Belo Horizonte. Como movimento de ocupação, o Duelo de MCs promove a reflexão crítica de grupos historicamente alijados das políticas públicas, tensiona a noção de público e reivindica questões ligadas à liberdade de expressão, identidade cultural e cidadania.

O presente trabalho visa compreender a trajetória da relação do Ministério da Cultura com o Ministério da Educação, quanto ao processo de construção de ações, programas e política cultural propriamente para as instituições de ensino superior brasileiras, durante o período de 2003 a 2013. Para um maior aprofundamento da análise dessa articulação, busca-se adotar como estudo de caso o processo de criação de dois programas específicos: Cultura e Universidade, criado em 2010 por meio de portaria assinada apenas pelo MinC, e o Programa Mais Cultura nas Universidades, por sua vez criado em 2013, a partir de portaria interministerial envolvendo os dois Ministérios, MinC e MEC. Durante o período de 2003 a 2013, nota-se que os termos universidades ou instituições de ensino superior estão presentes em instrumentos legais, programas e ações estratégicas do Ministério da Cultura e, mais pontualmente, com a participação do Ministério da Educação. Propõe-se assim, identificar uma trajetória cronológica a partir do mapeamento dessas iniciativas do MinC voltadas para o campo cultural das universidades, visando facilitar a reflexão sobre possíveis transformações, no âmbito das políticas públicas culturais voltadas para as instituições de ensino superior. Além da investigação de instrumentos normativos, documentos oficiais e recursos orçamentários alocados, a pesquisa buscará contextualizar como a criação dos Programas Cultura e Universidade e Mais Cultura nas Universidades parecem apontar para diferentes formas de articulação entre o MinC e o MEC, na formulação de políticas culturais para as universidades.

El presente proyecto nace de la necesidad de reconocer dentro de la ciudad de Constitución hitos arquitectónicos y/o urbanos de interés patrimonial que no presenten una protección ni reconocimiento legal, lo que no quiere decir que para la propia comunidad sean elementos irrelevantes, sino todo lo contrario, son elementos que los sienten como propios, como parte de su paisaje urbano y de su memoria histórica. En esta idea, es que el proyecto toma el caso de una vivienda familiar urbana de finales del siglo XIX muy característica de la zona central del país, cuyos propietarios son los descendientes del destacado político chileno Enrique Mac Iver Rodríguez. Con este panorama, es que el proyecto intenta salvaguardar este patrimonio arquitectónico de la ciudad generando una re funcionalización en su programa, entregando un espacio a la comunidad que por mucho tiempo estuvo completamente cerrado y que actualmente sufre las consecuencias del abandono.

The development of foreign activities by MNC (Multinational Corporations) raises the question of how do cultural differences affect their managerial practices, such as strategic planning which has always been source of academic debates and one of most widely used managerial tools. The cultural context in China is regarded as unique because of its continued evolution under the influence of traditional values, communist ideological factors and modern-day economic globalization. This research is interested in describing the practice of strategic planning of French MNCs in China, draw conclusions and formulate propositions related to the cultural context effects. Starting with a three-pronged analysis of strategy as practice, we then cross-examine the five current features of strategic planning in Western literature and the six groups of national and organizational cultural dimensions that MNC encounter in the Chinese context. Then, drawing from a qualitative case study, the experiences of French expatriates and Chinese managers help us construct a model of strategic practice, rendered accessible by using the metaphor of a "train", which includes both our conceptual and operative propositions

This Project Research is the result of our Master Thesis, which concerns the attitude of sharing knowledge among managers and employees across countries inside a Multinational Corporation.
This thesis deals with the question of how multinationals work with knowledge embedded in people which must be transferred within the company itself and among this latter and its subsidiaries.
According to the premise that knowledge is arguably one of the most important factor in today's economy, the key challenge for companies, therefore, is to develop, apply and then transfer knowledge, in order to improve the competitive advantage. On the bases of it, we would like to analyze the overall transfer knowledge process and from a human resources management point of view, we would like to individuate the stones which block this process and then to discuss the probable implications for multinationals.
We have chosen PROACT Group, a consultancy services, support and systems firm in the fields of storage and archiving as our case study.
This study involves a survey on thirty-two participants among managers and employees from the eight international subsidiaries of the PROACT Group. We have used a multilevel analysis, including top line level and bottom line level to retrieve comprehensive data on knowledge sharing to do an in-depth analysis of the staff's knowledge sharing in the organization. At bottom line level, this research tries to identify the employee's cognitive feelings of shared knowledge. At top line level, the manager's knowledge sharing behaviours with employees and the factors affecting knowledge sharing behaviours in teams. We also test moderating factors in both levels in order to get the willingness to share their knowledge in the organization.
This study examines three keys aspects which include transfer knowledge process, culture influences and incentives to deal with the barriers.

Organizational culture is a central theme within the field of organizational theory and it is essential to note that the cultural dimension affects all aspects of an organization. It informs the way individuals within a company think, value and react to ideas, opinions and notions that are in their essence cultural (Alvesson, 2015). The purpose of the study was to gain an increased understanding of a multinational corporation’s organizational culture within the digital camera industry, by comparing two offices located in different countries. One in the United Kingdom and the other in Sweden. This was achieved through a comparative study in order to shine a light on potential similarities and differences that might exist within a multinational corporation, where an individual’s cultural norms and values may shape the landscape of the organizational culture. Semi-structured interviews were conducted with a number of people with a leadership position within the company to gain insight on the culture within their respective offices. The result showed both commonalities and differences between the two offices regarding the organizational culture. Both offices shared practices regarding the distribution of work and held similar views on the treatment of coworkers. A prominent difference between the office's culture was the tone of communication and relationship between superiors and subordinates. The swedish office had quite a flat hierarchy and an informal style of communication compared to the british office, which leaned in the opposite direction to a degree.

CAPES
A partir do entendimento de que a deficiência é também produzida pela linguagem, buscamos, nesta tese, investigar qual a representação cultural da deficiência nos discursos midiáticos do Portal do Professor do MEC, especificando suas articulações com os saberes e poderes que operam na constituição desses sujeitos. O suporte teórico foi buscado em Michel Foucault e em autores ligados ao campo teórico dos Estudos Culturais de vertente pós-estruturalista, como Silva, Costa, Veiga - Neto, Wortmann, Silveira, entre outros. Michel Foucault oferece-nos as ferramentas teóricas e metodológicas com as quais podemos analisar os discursos, valendo-nos, também, das noções de saber, poder e objetivação. O corpus de análise consiste em um conjunto de documentos que vão desde as aulas produzidas no ―espaço da aula‖, passando pelas publicações no ―jornal do professor‖, em que se encontram artigos ligados à deficiência, aos discursos dos profissionais da educação veiculados nos vídeos institucionais, até músicas, artigos de revistas, histórias em quadrinhos (HQs), vídeos do youtube, textos da literatura infantil, que tomaram a deficiência por tema e a constituíram como objeto de conhecimento e de arte. Os achados da pesquisa mostram que a produção da deficiência, no espaço formativo do Portal, acontece por meio da articulação de diferentes discursos, evidenciando que esses sujeitos são construídos através dos saberes e poderes de diversas ciências, levando-nos a reconhecer que a deficiência nada mais é que a regularidade de certos temas, imagens e falas que se repetem em diferentes discursos. Em outras palavras, podemos dizer que os sujeitos que enunciam no Portal se apropriam e fazem circular discursos sobre a deficiência oriunda do campo da medicina, da psicologia, da pedagogia, do discurso da diversidade, da inclusão, além do discurso religioso, que se ocupam em nomear e narrar essas pessoas, fazendo surgir múltiplas representações culturais. Constatamos também que o discurso sobre a deficiência apresenta-se híbrido, pois, ao mesmo tempo em que se fundamenta num discurso inclusivo, afirmando o direito de ser diferente e enfatizando tudo aquilo que torna as pessoas com deficiência indivíduos verdadeiramente individuais, em contrapartida, atacam essa individualidade, fazendo aparecer um sujeito universal, reduzido nas conceitualizações médicas e psicológicas da deficiência. Outros achados revelam que a representação da deficiência fundamenta-se em um discurso antagônico, evidenciando que esses sujeitos vão sendo constituídos e significados de maneiras múltiplas, mas nem sempre de maneira harmônica ou linear. Assim, se por um lado temos a produção do herói deficiente, representado por discursos que enaltecem as capacidades sobre-humanas desses sujeitos, por outro lado temos os discursos que apresentam os sujeitos com deficiência a partir de suas incapacidades, de suas limitações e supostas ―faltas‖. Assim, poderíamos dizer que a pessoa com deficiência é, ao mesmo tempo, selvagem (monstro), e ainda o mais obediente e puro dos seres; ele é a encarnação do herói e, todavia, incapaz de realizar as tarefas mais simples; ele é inocente como uma criança e, todavia, é incitado a falar dos detalhes mais íntimos de sua vida amorosa e sexual. Nesse sentido, esperamos que nossa tese contribua de alguma forma para questionar as lentes com que as pessoas com deficiência são vistas, e com que enunciados esses indivíduos com deficiência são falados nos processos formativos virtuais, como aqueles que acontecem no Portal do Professor do MEC.

Biotechnology has for many years operated a large collection of microorganisms in food and health sectors. Today, this field fits perfectly into the ecological transition of chemical and environmental sectors, by designing high-performance processes to replace petroleum products. Filamentous fungi represent important organisms in industrial biotechnologies, widely used for the production of metabolites with strong commercial interests such as antibiotics, enzymes or organic acids. Their implementation in submerged environment is continually attracting new research to overcome issues associated with their behavior. Indeed, this mode of cultivation generates different fungal morphologies, mainly dependent on their intrinsic biological properties but also on physico-chemical conditions within their environment. This characteristic of filamentous fungi very often influences their implementation and their productivity.This thesis proposes an original study to identify and control the underlying phenomena that influence fungal morphogenesis. To this end, we propose research combining fundamental and applied studies on several strains of strong industrial interest. We have investigated and developed various pioneering techniques for the control of fungal morphology. Microparticles implementation and development of a microfluidic encapsulation technique allowed us to confirm and deepen the aggregation mechanisms of fungal conidia. On the other hand, the addition of mineral salts in the culture medium prevented hyphae aggregation. To validate an extrapolation of these results towards an industrial process, these tools were also implemented during the first steps of scale-up. These works bring results and perspectives in the control of bioprocesses involving filamentous fungi

The soil is a key component for the functioning of the Earth system and lies on the surface of the planet at the interfaces of the atmosphere, pedosphere, biosphere and lithosphere. However, this resource is affected by human pressures leading to an increase in degraded areas which eventually, become lost for agricultural purposes. This multidisciplinary research aimed to evaluate the expansion of sugarcane in the State of São Paulo, Brazil, considering climate projections and soil degradation resulting from erosion. Thus, the first methodological phase of this study established estimates of soil loss rates for the State of São Paulo by the Universal Soil Loss Equation (USLE), a model widely used in soil conservation studies. From this estimate, the Soil Lifetime Index was calculated, a diagnostic tool to assess the land degradation level, defined by the estimated erosion and soil renewal rates. This methodology was applied in two steps: i) first, we estimated the remaining time of degradation of the solum profile (horizons A + B) until reaching a critical depth of 1 m; ii) second, the remaining time for erosion loss of the nutrient-rich soil surface layer of 0.25 m. The results of these steps showed that the average estimated soil loss rate was 30 Mg ha$^{-1}$ yr$^{-1}$ and that the estimated soil loss rates exceeded the average tolerance limit, found in the literature, of 12 Mg ha$^{-1}$ yr-1, in 59\% of the area. Thus, in this part of the study, the conclusion was drawn that measures must be taken for the entire state of Sao Paulo in relation to soil conservation, especially with regard to agricultural management. The second methodological stage consisted in creating a model of sugarcane expansion to simulate the expansion of sugarcane fields in the State of São Paulo using LuccME, a modeling framework developed at the Center for Earth System Science (CCST), the National Institute for Space Research (INPE). Simulations were performed from 2005 to 2010, validation in 2012, resulting in projections for 2050. The data used were simulated air temperature and precipitation data of the Representative Concentration Pathway (RCP 4.5 and 8.5 from projections generated by the Hadley Centre Global Environment Model, version 2-Earth System (HadGEM2-ES) of the Coupled Model Intercomparison Project Phase 5 (CMIP5). These projections indicated an increase in air temperature and precipitation for the scenarios analyzed, as well as higher sugarcane yields in the future or future sugarcane yields, estimated by the Integrated Model of Surface Processes (INLAND). The climate projections RCP 4.5 and 8.5 were also considered in the simulations and both indicated yield increases, especially for 8.5 RCP. The results of the sugarcane expansion model showed a peak or an extreme result of 68.89\% compared with the CANASAT project for the same year. These results, compared to the results of the first phase of the work (soil degradation by erosion), indicated that by 2050, under the climate predictions of RCP 4.5, sugarcane expansion in the state of São Paulo will result in losses with regard to soil degradation, since the sugarcane fields will most likely have reached erosion-susceptible regions.

Those grains planted during summer are very important for the Brazilian economy because over 80\% of its' yearly production are grown during this season. So the objective of this work was to discriminate the summer cultures by the integration of multi-temporal data, obtained during several agricultural cycles, using the following data: TM/Landsat 5 images and cartographic data, an image analysis system, a geographic information system, and a relational data bank. The crops studied were: soybean (Glycine max (L) Merrill), maize(Zea mays L.) and cotton (Gossypium hirsutum L.). During field campaigns the following data were obtained: ground truth data for these crops referring to agricultural years 89/90 and 90/91, the intentions of planting for 91/92 in the region around the town of Guaíra, São Paulo State. The gray levels of the six reflected bands from TM/Landsat were extracted and transformed to reflectance values after atmospheric correction. Using data from bands TM (3), TM (4)and TM (5) the images were classified during the phases of soil preparation (Phase 0) and ripening/harvest (Phase 3). During the agricultural year 91/92, using the hybrid image classification method, and after performing "crossed tabulation" (GIS/INPE), were made projections that is, forecast of areas to be planted for each crop in that agricultural year. The main conclusions derived from this study are: the use of historical data referring to only two agricultural years (89/90 and 90/91), stored in a multi-temporal data bank, contributed to increase the classification accuracy of the image from Oct. 21st '91 to more than 80\%; the use of the imaqe from March 13th '92 did not show up a good result for the Fourth Projection, because by this time, over 25\% of the area was already harvested and over 70\% of the fields were at Phase 3 of the agricultural cycle. The result of this was confusion, specially at those fields with prepared soils. Being so, we suggest the use of images of an earlier date to obtain the Fourth Projection. The interface among Relational data bank/SITIM/GIS was easy to handle and allowed a good performance of image classification from Oct. 21st '91. The diversity of phenologic stages of summer crops that varied from fields of recently-germinated cultures to fields with completely dry cultures and soils in different stages of preparation, suggest the establishment of a larger number of data banks to improve the classification accuracy.

Problem addressed in this work is the development of a rational protocol for determining the reduction of viruses by membrane filtration in conditions close to those encountered in water treatment. To do this, were researched among the operating conditions, those leading to the largest transfer, in order to reveal possible weaknesses in the materials tested. In this study, bacteriophages MS2 and Qbeta were chosen as indicators. Their behaviors in suspension in various solvents, in static during contact with interfaces and in dynamic during filtration were studied. The protocol developped was then tested in various laboratory scales using virgin membrane and through membranes with one defect (hole). Finally the validation of the protocol has been conducted on pilot scale facilities supplied by two manufacturers. The detection and quantification methods used and compared are the cell culture (PFU method) and RT-PCR with and without extraction. These methods allow in a sample the determination of the various forms in which viral particles are likely to be present: infectious, disactivated and broken
Carmo, Inês Miguel Troles Duarte do. "Food waste valorization through the production of polyhydroxyalkanoates by mixed microbial cultures." Master's thesis, Faculdade de Ciências e Tecnologia, 2013. http://hdl.handle.net/10362/10454.
Polyhydroxyalkanoates (PHAs) are polyesters of hydroxyl fatty acids, which are accumulated in microbial cells as carbon/energy reserves. PHAs are bio-based and biodegradable and display a wide range of thermoplastic properties, being a promising alternative to conventional plastics. Presently, industrial PHA production was primarily based on pure microbial cultures. Although this process has high PHA production efficiency, it presents high costs associated with the use of chemically-defined feedstocks, and to the need for sterility. An attractive feature of mixed microbial cultures (MMCs) PHAs production is the ability to use waste/surplus feedstocks. Many industrial wastes are seasonally produced making it necessary find the best method of utilization of this feedstock on PHA production process. Two different approaches might be taken account: (1) stock of industrial wastes during their production for their use throughout the year. However, the high fermentability of these agro-industrial wastes makes them susceptible to degradation during storage period; (2) the use of different feedstocks over the year according its availability. It is thus important to study MMC’s response to different feedstocks. The aim of this work is study how MMC PHA production process is affected by a feedstock shift, using cheese whey (CW) and sugar cane molasses (SCM) as model feedstocks. The use of waste based feedstock by MMCs requires a previous conversion of sugars to organic acids (OAs), which is achieved through anaerobic fermentation. In this study, a three-stage MMC PHA process was used, comprising: (1) anaerobic fermentation of surplus feedstocks to produce OAs in a membrane bioreactor (AnMBR); (2) PHA accumulating culture selection in a sequencing batch reactor (SBR) under feast and famine conditions using fermented feedstocks; and (3) PHA production using the selected cultures and the OAs produced in the earlier stages. Initially the effect of both feedstocks (CW and, SCM) in the acidogenic fermentation (stage 1) was assessed. Firstly, the AnMBR was operated under steady state with CW. When the feedstock was changed to SCM an adaption period of about 10 to 15 days was observed. When SCM was replaced by CW a faster adaptation response, approximately 7 days, was observed. The AnMBR reached similar OAs profiles in both phases when CW was fed (% g-COD HAA/g-COD OAs): 65% acetate, 10% propionate, 22% butyrate, 2% valerate, and 1% lactate. These results demonstrate that the system’s performance is reproducible. On the other hand, the anaerobic fermentation of a different feedstock, SCM, resulted in a different OAs profile (%g-COD HAA/g-COD OAs): 24% acetate, 38% propionate, 19% butyrate, and 19% valerate. In a second phase, different fermented feedstocks were used in the selection of PHA-storing organisms under a feast and famine regime in a SBR (stage 2). Initially the SBR was fed with a synthetic OAs solution; then fermented SCM (fSCM) and fermented CW (fCW) were subsequently fed as they were produced in the AnMBR. The adaption of the MMC to fSCM was faster than the adaptation to fCW. Whenever steady state was reached, PHA accumulation tests were performed using the enriched MMC fed with the corresponding feedstock (stage 3), namely synthetic OAs solution, fSCM, and fCW. Storage yields of 0.74, 0.49, and 0.73 C-mol PHA/ C-mol OAs were obtained with synthetic OAs solution, fermented molasses, and fermented CW, respectively. The culture reached a maximum PHA content of 60%, 56% and 65%, when feedstock fed were synthetic OAs solution, fSCM and fCW, respectively. A direct relation between the used feedstock and the polymers composition was observed, which was related with the different OAs profile. Even though, the shift of complex feedstock in three-stage MMC PHA process is still at a very early stage of development, this work illustrates the advantage of favoring the selection of cultures with the capacity to adapt its metabolism to different feedstocks. This will offer the possibility of using numerous substrates and improving strategies to optimize acidogenic fermentation, culture selection and polymer production.

Brazilian agriculture is well-known for its significant role in the countrys economy and because of its importance in global markets. Although most regions of the country have high crop yields, this is not the case in large areas of the semiarid of Brazil-BSA. Low-income farmers of the region usually grow crops under rainfed conditions have low technological resources and almost no access to capital. Since most of the production of poor farmers is used for self-consumption and animal feed, typically maize, there is a close link between crop yield and food security. In this way, the ability to predict and monitor crop yields throughout the growing season is crucial to decision makers for the preparation of mitigation actions when needed. In this regard, the aim of this study was to demonstrate the feasibility of using regional climate model Eta operational seasonal forecasts as input to the FAO crop simulation model (AquaCrop) to predict maize crop yield in the BSA. To achieve this goal, field data from 37 controlled experiments in 13 municipalities were used to calibrate and validate the AquaCrop model, for the period from 1995 - 2010. Seasonal climate forecasts of precipitation, maximum and minimum temperature and evapotranspiration from 2001 through 2010 were bias corrected before use them in AquaCrop simulations. Soil hydraulic properties were derived from pedotransfer functions (PTFs). To simulate an operation crop forecast system, tat anticipate crop forecast, it was used seasonal climate forecast in combination with observed meteorological data. The calibration of the AquaCrop model proved to be efficient to remove systematic errors, which provided good precision of the maize yield estimates for BSA. The AquaCrop model estimates, using seasonal climate forecasts provided by Eta model, showed an excellent performance in predicting maize yield in the BSA with at least 30 days before harvest. In many of the municipalities analyzed, prediction with good accuracy can be achieved 60 days in advance. The best maize forecasts occurred in the EBSA region, related to the frequency of precipitation events in that region. The crop forecasting system presented in this study is a valuable tool to support the development of public policies related to the BSA region.
Oliveira, Pedro Valle de Carvalho e. "Detecção de culturas agrícolas em áreas desflorestadas para auxiliar a moratória da soja." Instituto Nacional de Pesquisas Espaciais, 2011. http://urlib.net/sid.inpe.br/mtc-m19/2011/04.12.16.23.
The Soy Moratorium was established in order to reduce deforestation caused by soybean expansion in the Amazon biome. It expresses the commitment of the Brazilian Association of Vegetable Oil Industries (ABIOVE) and the Brazilian Association of Grain Exporters (ANEC) not to trade soy produced in deforested areas after July 24$^{th}$, 2006. Currently, the presence of soybean in these areas is identified in two steps: 1) through satellite images from the MODIS sensor to identify crop areas; and 2) through an air survey to detect soy plantation. This study aims to improve the crop detection processes in deforested areas in order to assist the Soy Moratorium in Mato Grosso state. To accomplish this task it was first necessary to classify the deforested areas according to their shape and size; to evaluate the Enhanced Vegetation Index (EVI) spectral-temporal behavior for crop and non-crop sites, in order to identify patterns that facilitate the distinction among those land uses; to calculate different Rates of Change in EVI (TVE) in all MOD09Q1 composed images product, between July 2009 and February 2010 and to identify the TVE that presents best result for crop detection. Afterwards, each of the 127 polygons that were flown in Mato Grosso were classified as "small", "narrow", "small and narrow" and "normal". The EVI2 time-series analysis, calculated from the MOD09Q1 product for the 127 detected polygons in Mato Grosso, allowed identifying a crop pattern and several non-crop patterns. Based on this information, the TVE was calculated with 32, 40 and 48-day intervals with three different limit dates for each interval. It was observed that for rates greater than 0.4 the presence of agricultural crop was evident. It was noticed that, although the TVE with a 48-day interval, estimated on 11/02/10, presented the greatest accuracy (80.3\%) to identify crop and non-crop, it detected less soybean areas when compared to the 32 and 40-day TVE. The 32-day interval of TVE, estimated at 25/12/09 and 10/01/10, detected most of the number of polygons with soybean (42 and 53 of 56 polygons, respectively). The omission of agricultural polygons occurred only in those classified as "small" and "small and narrow". Thus, it is possible to conclude that, the crop detection process to assist the Soy Moratorium in the state of Mato Grosso can be improved using TVE.

The climate is related with all economic activities, especially to agriculture, which is the most dependent on climatic factors, and changes in these factors affect the productivity of crops with a direct impact on agribusiness. For Brazil, sugarcane crop has a great economic importance, considering that the country is the pioneer and leader in research and production of ethanol from sugarcane. Considering the importance of the culture and the influence that the elements of the climate, mainly the soil water deficits, can exert on its development, this work had the objective to evaluate this influence, in three states with greater production of sugarcane: Paulo, Minas Gerais and Paraná, besides estimating the agricultural productivity through a simple model and evaluating the performance of the same in relation to the references of the Brazilian Institute of Geography and Statistics (IBGE) and thus to provide subsidies for new strategies in the face of climatic variability. Rainfall and temperature meteorological data were used forobtaining the climatic standards of São Paulo, Minas Gerais and Paraná, from 1980 to 2010, as well as, to serve as input parameters of the agrometeorological model, to estimate sugarcane productivity. Agrometeorological simulations allowed to adequately estimates the potential productivity and estimated productivity through water deficit, varying from 140 Ton/ha in Minas Gerais to 107 Ton/ha in São Paulo, the highest losses occur in phase 3, growth of stems and vary from 40\% in São Paulo to 53\% in Minas Gerais. The values of productivities showed that the State of Minas Gerais was the one that presented the lowest values with 39 Ton/ha and the state of Paraná the largest, around 70 Ton/ha. Productivity percentages ranged from 53\% to 61\% in São Paulo, 27\% to 37\% in Minas Gerais and 54\% to 63\% in Paraná. The highest penalties occur in Minas Gerais with 53\% and the lowest losses in the State of Paraná and São Paulo, around 36\% to 38\%, showing that the crop is suitable for the climate in these regions. In the performance evaluation of the model, errors ranged from 6\% to 11\% in São Paulo, 11\% to 22\% in Minas Gerais and 11\% to 20\% in the State of Paraná, allowing the model to be considered an important tool for monitoring and estimation of the reduction of productivity in the sugarcane crop through water penalty.

A dissertação aqui apresentada insere-se no campo dos estudos sobre políticas públicas e gestão da educação, com o recorte de raça. O entendimento de que as leis são estabelecidas para um povo, uma nação e não para parcela dela faz parte deste estudo. Assim, a compreensão da implementação do artigo 26 A da Lei de Diretrizes e Bases (LDB) e de suas diretrizes como políticas públicas de educação é de interesse público e nacional e um preceito legal do Estado Brasileiro (Saviani, 2008, Cury, 2005 & Santos, 2003). Para tanto, o trabalho inicia-se com uma visão geral de como se constituiu uma ordem racista no Estado brasileiro, a história da educação no Brasil, com sua lógica excludente e a contribuição da eugenia para propagação do racismo na sociedade. Apresenta, ainda, parte dos estudos realizados pela Unesco, referentes à raça, que tinham o intuito de apresentar "um elogio da mestiçagem, assim como enfatizar a possibilidade do convívio harmonioso entre diferentes grupos humanos nas sociedades modernas" Fernandes, (2007:14), mas ao final, com as análises Roger Bastide e Florestan Fernandes, para a cidade de São Paulo, demonstraram as "falácias do mito": Ao invés da democracia, o que apareceu foi a discriminação e, no lugar da harmonia, o preconceito (idem). Neste trabalho, serão apresentados alguns fatos que levaram o Estado Brasileiro a impregnar-se com as ideologias de inferiorização do negro, como: a degenerescência do mestiço, o mito da democracia racial e o racismo individual, institucional e cultural, estes últimos baseados nos estudos de Jones, (1973). Tais fatos são decisivos para fazer do racismo uma atitude de senso comum no seio da sociedade. No campo da gestão da política pública de educação, a ênfase está na omissão que os gestores demonstram no que tange a presença das questões etnicorraciais nas ações do Ministério da Educação. Para isso, foram realizadas doze entrevistas, com diretores, coordenadoras e técnicos educacionais de duas secretarias do MEC, Secretaria de Educação Básica (SEB) e Secretaria de Educação Continuada, Alfabetização e Diversidade (Secad), nas quais os gestores puderam emitir suas opiniões sobre a implementação das políticas públicas e gestão da educação para o ensino de história e cultura Afro-brasileira e africana no âmbito do MEC. As análises das entrevistas tiveram por base os estudos culturais de Bogdan e Biklen, (1994), o método de análise de conteúdos e os procedimentos qualitativos de Triviños, (2008) e Creswell, (2007). _________________________________________________________________________________ ABSTRACT
This dissertation concerns studies on public policies and education management, with emphasis on race. Here, we discuss the perception that laws are established for the whole population and nation, and not parts of it. Hence, the understanding of the implementation of article 26 A of LDB and its directives as public policies of education is of public and national interest and a legal precept of the Brazilian Estate (Saviani, 2008, Cury, 2005 & Santos, 2003). This work begins with a general view of how a racist order was constituted in the Brazilian Estate, the history of education in Brazil, along with its excluding logic and the contribution of “Eugenia” to the propagation of racism in society. We also present part of the studies made by Unesco, where they intended to present “um elogio da mestiçagem”, as well as a highlight on the possibility of a harmonious relationship between different human groups in modern societies” (Fernandes 2007:14), but ended up, with the analysis of Roger Bastide e Floretan Fernandes, for the city of São Paulo, demonstrating the “fallacies of the myth”. Instead of democracy, they showed discrimination and instead of harmony, prejudice. In this work, we will present a number of facts that drove the Brazilian Estate to absorb ideologies that led to undervalue black people, such as the degeneration of the “mestiço”, the myth of racial democracy and individual, institutional and cultural racisms, these last ones based on the studies of Jones (1973). These facts are crucial to turn racism into an attitude of common sense in the midst of society. Concerning the management of educational public policies, emphasis is given to the disregard showed by managers towards the presence of etnicracial questions in the acions of the Ministry of Education (MEC). In order to assess this issue, twelve interviews were undertaken with directors, coordinators and educational technicians of two MEC Secretaries, the Secretary of Basic Education (SEB) and the Secretary of Continued Education, Alphabetization and Diversity (Secad). Here, the managers emitted their opinions about the implementation of public policies and about management of education for the teaching of Afro-Brazilian and African culture and history in the ambit of MEC. The analyses of the interviews were based on the cultural studies of Bogdan and Biklen (1994). The content analysis as well as the qualitative procedures followed the methods of Triviños, (2008) e Creswell, (2007).

The mapping of sugar cane cultivated area is important for the sugar and ethanol sectors, supporting decision making and the definition of market strategies. Traditionally, sugar cane monitoring has been performed through visual classification based on time series of medium resolution images. Although it provides accurate results, it is a time-consuming method due to the vast extensions of sugar cane crops in Brazil. As a result, the aim of this research was to develop a methodology that can automate the sugar cane mapping task. For this, we tested the integration of two major approaches of Artificial Intelligence: Object Based Image Analysis (OBIA) and Data Mining (DM). The study area comprises the cities of Ipuã, Guará and São Joaquim da Barra, located in the northwestern region of São Paulo state, which well represents the conditions of agriculture in the southern and southeastern regions of Brazil. The AIOO was used to emulate the interpreter knowledge in the process of sugar cane mapping, but the most important task in knowledge-based systems, and often difficult to achieve, is the acquisition of knowledge. Thus, MD techniques were employed for automatic generation of the knowledge model. The MD algorithm used was C4.5, which generates decision trees (DT) from a training set. A time series of Landsat images was acquired in order to represent the wide patterns variability within the sugar cane cycle. The objects were generated by the application of the multiresolution segmentation algorithm implemented in Definiens Developer$\textregistered$. Thereafter, the knowledge extraction process begins, which ends with the acquisition of DT. Once properly trained, the DT was applied to the Landsat time series and then generated the thematic map. In the way to compare the obtained results with conventional systems of automatic classification, a classification with the ISOSEG algorithm was generated using the same data base used by OBIA. Then, the results of both classification methods were cross-checked with a reference map for validation and comparison of performance. AIOO classification showed significantly superior performance, achieving an overall accuracy of 94\% against 81.81\% of ISOSEG classification. The result shows that it is possible to automate the sugar cane classification process with the proposed methodology.

Resumo: O câncer de próstata (PCa) é o segundo tipo de câncer mais frequente e tem a segunda maior taxa de morbidade e mortalidade entre os homens. A cultura de células prostáticas LNCaP e PC3 tem sido utilizada para investigar possíveis alvos e vias de sinalização celular importantes para o crescimento e progressão do CaP. Trabalhos anteriores do nosso laboratório demonstraram que a presença de fibronectina no meio de cultura altera significativamente o padrão de expressão gênica dessas células. Também, bacteriófagos recentemente usados como agentes terapêuticos no tratamento de vários tipos de câncer, diretamente ou portadores de moléculas antitumorais, incluindo câncer de próstata, foram relatados. Estudos anteriores mostraram que bacteriófagos podem interagir com proteínas de membrana de células de mamíferos, incluindo integrinas que reconhecem sequências de RGD em proteínas virais, bem como fibronectina e outras moléculas da matriz extracelular. O objetivo deste projeto foi caracterizar a interação de três bacteriófagos com as duas linhagens celulares epiteliais prostáticas LNCaP e PC3. Estas duas linhas celulares foram cultivadas em seus meios de cultura, nos quais foram adicionados bacteriófagos com concentrações definidas. As células foram coletadas após 24 horas de tratamento. A expressão gênica de genes relacionados as vias integrinas ITGA5, ITGAV, ITGB1, ITGB3, ITGB5, AKT, PI3K, MAPK1, MAPK3, HSP27, HSP90, receptor de androgênio AR, STAT3, PGC1A foi analisada por qPCR.

Agriculture, besides providing food and energy, is one of the most prominent economic activities in Brazilian exports. Products derived from soy, corn and sugar cane are some examples of exported agricultural commodities. Thus, information related to the acreage and the production of these crops are essential, since this affects the price of these products. The adoption of remote sensing data for research in agricultural areas is a viable and complementary alternative to current surveying methods, providing updated and continuous information. These surveys generally use spectral information as the main variable for several purposes such as mapping, forecast yield, biomass estimation, etc. However, different management practices (with or without irrigation, planting time, etc.) employed in the production process can alter the spectral characteristics of the crop. In this sense, the present work has as hypothesis that the intraspecific spectral variation of corn, soybean and sugarcane from multitemporal OLI sensor spectral data, is smaller than the interspecific variation, independently of the management practices adopted during crops development. Thus, the objective of this work was to analyze the spectrumtemporal profile of soybean, maize and sugarcane crops grown in an area of the mesoregion of Campinas, SP, in two full agricultural years (2014/2015 and 2015/2016 ), from OLI/Landsat-8 sensor images, and to verify the spectral-temporal differences of the cultures. Time series of OLI images were used to acquire the spectrum-temporal profile of the three species cultivated at different times (springsummer and summer-fall) and under different management (irrigated and nonirrigated). Six spectral bands (B2-B7) of the OLI sensor and two vegetation indices (NDVI and EVI) were used, which were calculated from the reflectance value of the bands. Based on the spectral-temporal information (bands and vegetation indices), a hierarchical cluster analysis was performed. From the results, it was possible to identify that the spectral bands (B2-B7) were more efficient when compared with the vegetation indexes, for the division and generation of clusters of each culture, thus, to analyze the influence of cultural practices. In addition, a set of spectral bands, formed by the three bands (B5-B6-B4) commonly used for visual interpretation of agricultural targets, generated the same result of the analysis based on the six bands. With the results, it is possible to infer that the intraspecific spectrum-temporal variation is smaller than the interspecific spectral-temporal variation, independently of the management practices employed.
