Poisson, Charles. "Optimisation de films complexes PE/Liant/PA à propriétés d'usage maîtrisées." Lille 1, 2005. http://www.theses.fr/2005LIL10152.
Full textThe modification of the microstructure and the interdiffusion as well as the intermolecular interactions induced by addition of EVA in the PE layer PE/binder/PA packaging films improve the seal ability and the optical properties without degradation of the mechanical and adhesion performances. Only the sleep ability is deteriorated. The addition of EVA in the tie layer improve the PEgMAH/PA6-66 adhesion properties modification of the type and the density of the intermolecular interactions between tie layer, PA and EVA. The substitution of a linear PA6 by a branched leads to a degradation of the PEgMAH/PA6 adhesion properties which is mainly controlled by the contact time between the polymers. The slip ability was adjusted by addition of slip agents in the (PE+EVA) layer whose efficiency is limited by the presence of the adjacent layers and the formation of a non-uniform lubricating layer. The use of nanofillers in the PA6 layer leads to an improvement of the mechanical properties but a limited reduction of the gas permeability
Liu, Yazhao. "Photo-responsive systems in aqueous solution : from model polyelectrolytes to polyelectrolyte-surfactant complexes." Thesis, Strasbourg, 2021. http://www.theses.fr/2021STRAE007.
Full textThis thesis aims at designing, synthesizing and characterizing model photo-responsive systems in aqueous solution. These systems are based on polyelectrolytes (PEs) and surfactants. The photo-sensitivity arises from the presence of azobenzene (Azo) groups that undergo a transition from a trans to a cis isomer. We first considered a hydrophilic PE on which we grafted Azo groups. This system forms globular aggregates in solution due to chains collapse and intermolecular associations. The size of the aggregates varies under UV irradiation. It also depends on the molar mass of the PEs and the Azo content. We then considered surfactants in which Azo groups have been introduced (Azo-surfactants). We studied their complexation with oppositely charged PEs. These systems show a pearl necklace organization. The PEs decorate the micelles and penetrate inside (co-micellisation). Under UV irradiation, the size of the pearls decreases without really modifying the general organization of the complexes. Finally, we were interested in the self-assembly of Azo-surfactants and co-surfactants. This mixture leads to the formation of wormlike micelles and the creation of a gel. Under UV irradiation, a gel - fluid transition is observed. The origin of this phenomenon is linked to a morphological transition of the micellar aggregates (wormlike micelles - globular micelles)

Resumo: O estado de Pernambuco passa por um período de reestruturação econômica e territorial dinamizado, entre outros vetores, pela construção e consolidação de uma infraestrutura logística voltada para o mercado externo ¿ com destaque para o porto de Suape e sua estratégia de concentrar cargas a nível internacional; por empreendimentos estruturadores lastreados pelo governo federal ¿ com destaque para a Refinaria Abreu e Lima - RNEST, a Petroquímica Suape ¿ PQS e o Estaleiro Atlântico Sul - EAS, todos no Complexo Industrial e Portuário de Suape - CIPS; e por investimentos privados atraídos por incentivos fiscais. Objetiva-se verificar se os investimentos recentes no CIPS ocorrem de forma articulada de modo a promover a integração inter setorial da economia local e/ou no sentido de integrá-la aos circuitos de valorização de capitais extra-locais, nacionais e internacionais. A hipótese que se demonstrará é que tais investimentos não ocorrem de formar a aumentar a integração da estrutura produtiva pernambucana, mas obedecem a outras determinações impostas pelo atual padrão de acumulação capitalista
Abstract: The state of Pernambuco is going through a dynamic economic and territorial restructure period, among others, the construction and consolidation of a dedicated logistics infrastructure for external market ¿ special highlight to the port of Suape and its strategy to become an international hub port; by structuring ventures backed by the federal government ¿ especially the Abreu e Lima refinery ¿ RNEST, the Petrochemical Suape ¿ PQS, and the South Atlantic Shipyard ¿ EAS, all in the Industrial and Port Complex of Suape - CIPS; and private investments attracted by tax incentives for the same region. The purpose is to verify whether recent investments in CIPS occurs in an articulated manner to promote economic and territorial restructure to strength the integration of the local economy and/or to integrate it to the circuits of extra-local capitals.Thus, this study will consider the hypothesis that such investments do not pccur in an articulated manner to integrate productive structure of Pernambuco, but follow other determinations imposed by the new pattern of capitalist accumulation

Full textEstuda os possíveis impactos socioambientais da implantação do Complexo Turístico Imobiliário The Reef Club na cidade de Barreiros-PE. Estes empreendimentos resultam da integração dos resorts com o turismo residencial, demandam investimentos na casa dos bilhões de reais e provocam fortes transformações onde se instalam. Se expandem rapidamente na costa nordestina em função de condições extremamente favoráveis para a expansão do capital especulativo. O fio condutor do estudo foi comprovar a incapacidade do The Reef Club , e o modelo que ele representa, de promover a reversão da fragilidade socioambiental e econômica de Barreiros. Para que isto fosse possível foi estabelecido como objetivo principal a identificação dos possíveis impactos socioambientais que a comunidade poderá sofrer com a chegada do The Reef Club , possibilitando ao final a identificação de alternativas à este modelo que possibilitassem a melhoria das condições de vida, justiça social, respeito a natureza e o fortalecimento do capital social da comunidade barreirense. Os objetivos específicos estabelecidos foram a análise da atual situação da atividade turístico-imobiliária no Brasil e no exterior; o atual quadro de ocupação da zona costeira nordestina pela atividade turística; o processo de desenvolvimento do turismo tradicional, face a inexistência de projetos turísticos imobiliários em fase efetiva de funcionamento na região; e por último a análise do projeto de implantação do empreendimento The Reef Club e da estrutura socioambiental, econômica e institucional do município de Barreiros. Para que os objetivos fossem atingidos a pesquisa se desenvolveu de forma exploratória e qualitativa com base na triangulação de métodos (MINAYO, 2005), se utilizando de técnicas como a pesquisa bibliográfica, pesquisa documental, entrevista, observação assistemática e registro fotográfico. A análise e interpretação dos dados da pesquisa permitiram que ao final fosse possível concluir pela incapacidade do modelo turístico-imobiliário de reverter o grave quadro de fragilidade social de Barreiros, haja vista seu caráter eminentemente capitalista e especulativo, e que diante desta da fragilidade o quadro deverá se agravar. Ao final sugere-se que outras pesquisas se aprofundem no tema, tendo em vista a incipiência de estudos que abordem a problemática do excessivo processo de ocupação da zona costeira nordestina pela atividade turístico-imobiliária. Com forma de contribuir com a reversão da fragilidade socioambiental e econômica de Barreiros, sugerem-se alternativas, como a da Prainha do Canto Verde, no Ceará, que passam por modelos baseados na educação, participação e envolvimento da comunidade, que ao mesmo tempo em que a empoderam, possibilitam a formação do capital social, em um ciclo virtuoso que, ao contrário do capital econômico, não se acaba, pondo fim aos nativos mudos , formando-se, então, uma rede de solidariedade e comportamento recíproco, onde os valores sociais e culturais são partilhados

Na fase primária da infecção pelo HIV, o vírus penetra no Sistema Nervoso Central (SNC) e estabelece um reservatório viral protegido. A infecção crônica do SNC pode levar a complicações neurodegenerativas com a possibilidade de gerar transtornos da função cognitiva e déficits dos processos mentais, tais como atenção, aprendizado, memória, rapidez do processamento de informações, capacidade de resolução de problemas e sintomas sensoriais e motores. O Distúrbio Neurocognitivo Associados ao HIV (HAND) tem merecido atenção devido ao potencial em determinar impacto funcional desfavorável na vida das pessoas vivendo com HIV (PVHIV), como dificuldade na execução das atividades da vida diária e necessidade de assistência para garantir adesão às medicações. Além disso, os pacientes apresentam dificuldade em manter seus empregos, necessitando de uma melhor assistência social. O diagnóstico clínico do HAND é idealmente baseado no desempenho dos testes neuropsicológicos. Entretanto, a aplicação destes testes é impraticável em muitos cenários clínicos, principalmente em países subdesenvolvidos. A Escala Internacional de Demência pelo HIV (IHDS) é um teste de triagem rápido, validado para a população brasileira que, de acordo com o ponto de corte estabelecido, pode detectar todas as formas do HAND (assintomática, leve e demência). Realizamos um estudo transversal, com comparação de grupos, para estimar a freqüência do HAND por meio da IHDS. As variáveis quantitativas foram descritas por meio de média, enquanto que as qualitativas foram representadas por distribuição de freqüência. As associações dos fatores relacionados ao HAND foram testadas utilizando o teste Qui-Quadrado de Pearson. Foram estudadas 98 PVHIV entre 18 e 50 anos, sem outras doenças neurológicas e psiquiátricas, atendidas nos ambulatórios de dois centros de referências para o tratamento do HIV em Recife- PE. Também foram excluídas da pesquisa as pessoas em uso de efavirenz e drogas ilícitas nos 30 dias que antecederam a entrevista. Utilizou-se como critério diagnóstico do HAND um ponto de corte ≥ 11 na IHDS, cuja sensibilidade e especificidade é de 78% e 52%, respectivamente. Encontrou-se uma elevada prevalência (66,7%) do HAND e uma associação entre o distúrbio e as pessoas com mais idade e do sexo feminino. O diagnóstico de depressão e o uso de terapia antirretrovial (TARV) com menor penetração no SNC (CPE < 8) foi mais freqüente entre as mulheres e essa associação foi estatisticamente significante (P = 0,001 e P = 0,028, respectivamente), o que poderia justificar a maior prevalência do HAND no sexo feminino. Esse trabalho alerta para a necessidade de se realizar uma triagem nas PVHIV para o HAND uma vez que parece uma comorbidade frequente, principalmente entre as pessoas com mais idade e do sexo feminino, com a finalidade de auxiliar nas estratégias de melhoria à adesão terapêutica e na oferta de TARV com maior efetividade de penetração no SNC e de medicações psicotrópicas quando necessárias.

The main goal of this study was to evaluate the structure of a forest fragment in the municipal district of Catende/PE, seeking to subsidize future actions that can conserve and/or recover the forest fragment of Usina Catende. The study was accomplished in the fragment denominated “Forest of the Chinkens”, located in the Engenho Huimatá. The phytosociologic structure was determined with use of 14 plots of 10x25m (250m2), distributed in parallel lines with 50 meters among lines and plots. It was measured all the sampled trees with circumferences at the breast height (CBH) equal or superior to 10 cm. In the trees with bifurcation all the trunks were measured. The following phytosociologic variables were measured: density, frequency, dominance, importance value (IV) and sociological position. The estimate of the phytosociologic parameters were obtained with the use of the software “Native Forest”. The analysis of sampling sufficiency of the floristic composition was accomplished through the methodology of the specie distribution curves by area. For the diameters and height distribution it was considered class of 5 cm and 2 m, respectively. With the sample sufficiency accomplished it was observed 438 tres/3.500m2 with 63 species distributed in 29 families which 46 were identified at the species level, 11 at gender level, 2 at the family level e 4 were not identified. The families that presented larger frequency were Moraceae, Lecythidaceae,Mimosaceae and Anacardiaceae. The fragment presented index of diversity of Shannon-Weaver of 3,43 nats./ind. being compatible with other studies in Pernambuco. The ten species with larger values of IV were Brosimum discolor, Parkia pendula, Eschweilera ovata, Thyrsodium spruceanum, Tapirira guianensis, Protium heptaphyllum, Casearia arborea, Helicostylis tomentosa, Dialium guianense and Schefflera morototoni, tha represented 57,99; 41,74; 64,60 and 54,78%, of density, frequency, dominancy and importance value of the total sampled species. In the evaluation of the height it was observed a minimum height of 3,6 m and maximum of 22,00 m, with average of 8,67 m and standard deviation of 4,04 m. it was verified that 10 species were in three strata: Brosimum discolor, Brosimum sp.,Casearia arborea, Cecropia palmata, Dialium guianense, Escweilera ovata, Himatanthus phagedaenicus, inga fagifolia, Protium heptaphyllum and Thyrsodium spruceanum. The studied fragment presents low floristic diversity although it presents compatible diversity with other studies accomplished in Atlantic Forest. The families of larger importance in the study were Moraceae, Anacardiaceae and Lecythidadeae. Among the main sampled just the Brosimum discolor, Eschweilera ovata and Thyrsodium spruceanum presented a regular sociological position. The total diameter structure was similar to even aged forests, with the distribution in decreasing geometric form (inverted J). The studied fragment possesses little relevance; however, if considered jointly with other fragments of the area, its diversity is significant, justifying efforts to its conservation and management in landscape scale.
Objetivou-se avaliar a estrutura de um fragmento florestal no Município de Catende/PE, visando subsidiar futuras ações que possam conservar e/ou recuperar os fragmentos da Usina Catende. O estudo foi realizado no fragmento florestal denominado Mata das Galinhas, localizado no Engenho Humaitá. A estrutura fitossociológica foi determinada com o uso de 14 parcelas de 10 x 25 m (250 m2) distribuídas em linhas paralelas com 50 m entre linhas e entre parcelas. Foram mensuradas todas as árvores com circunferência igual ou superior a 10 cm a altura de 1,30m solo (CAP). Para cada árvore amostrada, mediu-se CAP e estimou a altura. Nas árvores com bifurcações foram mensurados todos os fustes. Em seguida foram estimados os valores da fitossociológica tais como: densidade, freqüência e dominância e valor de importância (VI), e determinou-se, ainda, a posição sociológica. A estimativa da diversidade foi obtida utilizando-se o índice de diversidade de Shannon. Os cálculos das estimativas dos parâmetros fitossociológicos foram obtidos por meio do uso do programa de informática Mata Nativa. A análise da suficiência amostral da composição florística foi realizada através da metodologia de curva de distribuição de espécies por área. Para o estudo da distribuição hipsométrica e diamétrica foram consideradas amplitudes de classe de 2 m e 5 cm, respectivamente. De acordo com a análise de suficiência amostral realizada, o número de parcelas utilizadas pôde contribuir com resultados confiáveis da composição florística mais representativa da vegetação estudada, bem como, das estimativas dos parâmetros fitossociológicos encontrados. No levantamento da composição florística foram observados 438 indivíduos/3500m2 e 63 espécies, distribuídas em 29 famílias, as quais 46 foram identificadas ao nível de espécie, 11 ao nível de gênero, 2 ao nível de família e 4 não identificadas. As famílias que apresentaram maior freqüência foram a Moraceae, Lecythidaceae, Mimosaceae e Anacardiaceae. O fragmento apresentou índice de diversidade de Shannon-Weaver de 3,43 nats/ind, sendo compatível com outros estudos em Pernambuco. As dez espécies com maiores valores de VI foram Brosimum discolor, Parkia pendula, Eschweilera ovata, Thyrsodium spruceanum, Tapirira guianensis, Protium heptaphyllum, Casearia arborea, Helicostylis tomentosa, Dialium guianense e Schefflera morototoni, e representaram 57,99, 41,74, 64,60 e 54, 78%,respectivamente, da densidade, da freqüência, da dominância e do valor de importância do total das espécies amostradas. Na avaliação da altura observou-se uma altura mínima de 3,6 m e máxima de 22,00 m, tendo como média 8,67 m e desvio padrão igual a 4,04 m. Verificou-se que 10 espécies encontram-se nos três estratos, que são: Brosimum discolor; Brosimum sp.; Casearia arborea; Cecropia palmata; Dialium guianense; Eschweilera ovata; Himatanthus phagedaenicus; Inga fagifolia; Protium heptaphyllum e Thyrsodium spruceanum. O fragmento estudado apresenta baixa riqueza florística, embora apresente diversidade compatível com outros estudos realizados em Mata atlântica. As famílias de maior importância no estudo foram Moraceae, Anacardiaceae e Lecythidaceae. Entre as principais espécies amostradas, apenas o Brosimum discolor Schott., Eschweelera ovata e Thryrsodium spruceanum apresentaram uma posição sociológica regular. A estrutura diamétrica total da floresta apresentou comportamento previsto para florestas ineqüiâneas, com a distribuição em forma geométrica decrescente (J invertido). O fragmento estudado possui pouca relevância; entretanto, se considerado conjuntamente com outros fragmentos da área, sua diversidade é significativa, o que justificaria esforços para sua conservação e manejo em escala de paisagem

Full textThe present contribution deals with the coordination chemistry of ambiphilic ligands, featuring both Lewis base and Lewis acid sites. In particular, the role that can play the Lewis acid within the coordination sphere of the metal is investigated, thanks to combined experimental and computational analyses. The first chapter introduces the context and main goals of this work. The second chapter focuses on the study of metal->Lewis acid interactions supported by ambiphilic ligands. A description of the very nature of the Au->B interaction is proposed in the case of diphosphine borane complexes. The influence of the nature of the metallic fragment on the M->B interaction strength is also assessed through in depth study of seven isoelectronic triphosphine borane complexes. The third chapter tackled the limit of existence of M?B interactions by combining a weakly basic metal with flexible ligands. Multi-centre coordination modes are evidenced within a family of copper mono- and di- phosphine borane complexes. This study demonstrates the ability of ambiphilic ligands to adapt their coordination to the electronic demand of the metal centre. In the forth chapter, the influence of the Lewis acid nature on the coordination mode of ambiphilic ligands is investigated. Unexpectedly, the complexation of di- and tri- phosphine alane ligands to gold leads to zwitterionic complexes, resulting from the internal activation of the M-X bond by the Lewis acid. In contrast, the complexation of phosphine gallane ligands affords both neutral and zwitterionic coordination isomers, isolable or exchanging depending on the number of donor buttresses

O que as paisagens tem a dizer sobre a sociedade e/ou comunidades? A paisagem é especificada pela subjetividade cultural assim como se refere a objetos concretos e ecossistemas ecológicos, é a interação complexa desses termos. Contudo, as paisagens estão imbuídas de significados e significantes, que dependem do parâmetro tempo, da historicidade. A memória conecta com um passado imagético, ajuda a reconhecer nos elementos simbólicos e nas representações sociais valores socioculturais e ambientais. Desta forma, aquela contribui para a avaliação de mudanças na paisagem. Nesta dissertação, a paisagem a ser estudada é a da Comunidade Quilombola Onze Negras no Cabo de Santo Agostinho, Pernambuco. As imagens nos arquivos mentais pessoais podem ser acessados com um trabalho construído por uma outra imagem, a fotográfica. Esta estimula a expressão individual e coletiva, mostra mais das histórias de um povo do que qualquer documento descritivo individual, que se pretende verificar. Quando as imagens são captadas pela própria comunidade quilombola por suas representantes mulheres, revelam seus valores, elementos simbólicos e a análise do discurso visual permitirá esclarecer como está a paisagem, o ambiente e assim propiciar uma ação ambiental que resulta na práxis de estimular a superação da contradição opressor-oprimidos . Esta contradição está presente na cultura da mata sul pernambucana dentro da fábrica no campo , a indústria da cana de açúcar. Não se sabe, porém, se este modelo continuará a ser reproduzido no novo sistema econômico que se estabelece na região: o complexo industrial portuário. Sabe-se que a atividade industrial influi diretamente no montante do PIB, elevando a renda, que está ligado ao IDH, índice que avalia se o desenvolvimento está se convertendo em benefício social, mas não em qualidade de vida. A proposta desta discussão é avaliar como está a paisagem e suas mudanças na comunidade quilombola Onze Negras, verificar uma correlação entre as imagens, a paisagem e os índices; e se as melhorias dos índices são reproduzidas pelas imagens

This study aims to understand the territorial transformations that is related to the advent of scientific-technical-information period, through which Ipojuca town has been undergone. Ipojuca is located in Pernambuco State, in Brazil. We have tried to understand how the techniques and standards imposed by hegemonic agents have been vertically articulated to suit the territory to the market needs. As a methodological design, this research has been developed from bibliographic survey and visits to Ipojuca in order to understand the roles played by several elements that are part of this process, thus, enabling the comprehension of its social and territorial dynamics. The study also shows that the profound transformations that refigure the territory of Ipojuca started in 1975 with the implementation of the Industrial Port Complex of Suape (IPSC) which generated conflicts, concerning the use and occupation of the soil. It has been observed that the connection between the Capital and the State created the conditions necessary for the installation of a new technical system represented by the IPSC, as well as standards that ensured the adequacy of this territory to the imperative of the market. Thus, it has resulted in an exclusive process of the division of territory. One of the consequences of the actions of this mega-enterprise was the expulsion of the local communities who had lived there more than 200 years and were forced to occupy part of this territory with the construction of slums and stilts. On the other hand, the economic agents, through public funding, modernized portions of this territory with the construction of urban projects, such as, “Planned Neighborhoods”. This dynamic made oppositions when it comes to the fact that, on one side, the population is living in irregular land occupations and, on the other hand, those with better economical power is expanding the social and territorial segregation. The relationship between the hegemonic agents of the national/international capital have been using the technique, science and information intensively, as well as the various State entities in their favor to impose the logic business where space is only seen by its exchange value, neglecting its value in use. Thus, it has been noted that both the technical and the legal system have been seen as factors that increase the of social and territorial inequalities and vulnerabilities which have been observed in Ipojuca town.
Este trabalho busca entender as transformações territoriais pelas quais passa o município do Ipojuca localizado no Estado de Pernambuco-Brasil, relacionadas ao advento do período técnico-científico-informacional. Procurou-se compreender como as técnicas e as normas impostas verticalmente pelos agentes hegemônicos foram se articulado para adequar o território as necessidades do mercado. A pesquisa foi desenvolvida a partir de levantamento bibliográfico e de visitas a este município para o entendimento dos papéis desenvolvidos pelos diversos elementos que fazem parte desse processo, possibilitando a compreensão de sua dinâmica socioterritorial. O estudo mostra que as profundas transformações que reconfiguram o território do Ipojuca começam a partir de 1975 com a implantação do Complexo Industrial Portuário do Suape (CIPS) que gerou conflitos relativos ao uso e ocupação do solo. Observou-se que a comunhão entre Capital e Estado criou as condições necessárias para a instalação de um novo sistema técnico representado pelo CIPS, e normas que garantiram a adequação deste território ao imperativo do mercado, tendo como consequência um processo excludente de divisão do território. Uma das consequências das ações deste megaempreendimento foi a expulsão das comunidades locais que ali residiam a mais de 200 anos e que foram obrigadas a ocupar parte deste território com a construção de favelas e palafitas. Por outro lado os agentes econômicos imobiliários, através de financiamentos públicos, modernizam parcelas deste território com a construção de projetos urbanísticos denominados ‘Bairros Planejados’. Esta dinâmica opondo, de um lado, a população que mora em ocupações irregulares e, do outro, aquelas com melhores poderes aquisitivo está ampliando a segregação socioterritorial. A relação entre os agentes hegemônicos do capital nacional e internacional utilizando-se intensivamente da técnica, da ciência e da informação e os diversos entes do Estado vai impondo uma lógica corporativa onde o espaço é visto apenas pelo seu valor de troca negligenciando seu valor de uso. Desta maneira, tanto o sistema técnico, quanto o normativo, constituiram-se como fatores de ampliação das desigualdades e das vulnerabilidades sociais e territoriais observadas no município do Ipojuca.

No ultimo quartel do século XX, o processo genericamente chamado de reestruturação produtiva alterou significativamente a relação entre o capital e o trabalho. O novo cenário é marcado, sobretudo, pela flexibilização dos direitos historicamente adquiridos pelos trabalhadores, o que implica na precarização das condições de trabalhado. Diante disso, os sindicatos e o sindicalismo são chamados a responder à altura os novos desafios colocados. Sendo assim, a presente pesquisa tem como objetivo reconstruir descritivamente a greve dos trabalhadores da construção civil, ocorrida entre fevereiro e março de 2011 no Complexo Industrial e Portuário de Suape. Através da reconstituição refletimos como tem ocorrido a articulação politica e mobilização social desses trabalhadores. Recompomos o processo da greve através da utilização das atas das audiências ocorridas na Procuradoria Regional do Trabalho (PRT – 6ª Região) bem como a partir de entrevistas semi-estruturadas realizada com sujeitos participantes do processo. Para a reconstrução da greve, aproximamos-nos do contexto e da dinâmica do sindicalismo no Brasil, analisando seus momentos de crise e ascensão. Situamos, também, a emergência e consolidação do Complexo Industrial e Portuário de Suape (CIPS). A partir da reconstrução descritiva da greve em questão, identificamos quem foram os principais atores envolvidos, a dinâmica conflitiva da relação entre esses atores, bem como as formas de articulação e mobilização especificas forjadas por estes atores que atuam no setor da construção civil. Destacamos, em particular, a questão da relação entre os órgãos sindicais e trabalhadores.

CAPES
O presente estudo tem como objetivo geral compreender as transformações socioespaciais a partir da implantação do Complexo Industrial e Portuário de Suape (CIPS) e seu impacto para as mudanças no território frente às novas dinâmicas socioespaciais. Para tanto, nos apoiamos no materialismo histórico dialético, com o intuito de desvelar os processos socioespaciais que ora ocorrem na área de estudo. O estado de Pernambuco figura entre as maiores economias da região nordeste quando tratamos de desenvolvimento regional, este impulso é motivado em grande parte, pelos investimentos públicos e privados realizados no porto de Suape, que iniciou sua operacionalização em abril de 1984, e hoje possui um dos maiores complexos industriais e portuários do país. O interesse pelo tema surgiu em virtude da constatação da importância que o Complexo Industrial e Portuário de Suape (CIPS) tem para o crescimento socioeconômico no estado de Pernambuco, onde o território estratégico de Suape se transformou em uma região com grandes potenciais de geração de emprego e desenvolvimento, o que impulsiona uma nova dinâmica socioespacial e fortes transformações no território, modificações nem sempre harmoniosas na relação porto e cidade. Dessa forma, chamamos a atenção para as externalidades advindas da dinâmica socioespacial e do processo de territorialização do Complexo Industrial e Portuário de Suape - PE. Assim, os procedimentos metodológicos desenvolvidos primaram pela pesquisa bibliográfica, documental e de campo. Na pesquisa bibliográfica realizamos uma reflexão teórica acerca das questões territoriais, e do processo de globalização e como isso impulsionou o desenvolvimento das cidades portuárias.
This study has the general objective to understand the socio-spatial transformations from the implementation of the Industrial and Port Complex of Suape (CIPS) and its impact on the changes in the territory in the face of new dynamics sociospatial. For this, we rely on historical dialectic materialism, in order to reveal the socio-spatial processes that sometimes occur in the study area. The state of Pernambuco is among the largest economies in the northeast when dealing with regional development, this impulse is motivated largely by private and public investments in the port of Suape, which started its operation in April 1984, and today it has a the largest industrial complex and port of the country. Interest in the subject arose because of the realization of the importance that the Industrial and Port Complex of Suape (CIPS) has for socio-economic growth in the state of Pernambuco, where the strategic territory of Suape has become a region with great potential for employment generation and development, which drives a new socio-spatial dynamics and strong changes in the territory, changes not always harmonious relationship in the harbor and city. Thus, we call attention to the externalities arising from socio-spatial dynamics and Industrial Complex territorialization process and Port of Suape - PE. Thus, the developed methodological procedures were conspicuous by their literature, documentary and field. In the literature we carried out a theoretical reflection about the territorial issues, and the process of globalization and how it spurred the development of port cities.

Full textThis study analyzes the formalization of manufacturing industrial enterprises in the city of Caruaru. The region of Agreste Pernambucanoé's Clothing Complex is composed of several municipalities, including Caruaru, with a significant production of clothing articles. This productive cluster was formed during the 1950s, and its activities have been developing informally from the outset. However, since 1990, it has been undergoing increasing processes of modernization, industrialization and a growing overlap with the capitalist dynamic, attracting the action of the state and of the capital. One of the main changes is the tax regularization of productive plants. Considering this reality, we observe the industry formalization process: workshops which began operations predominantly in households with family and informal labor force and became confection factories. The research problem considers that historical and dominant informality, both of production units as of labor relations, is being reconfigured by the formalization process. The analysis mobilizes the conceptual discussion of informality, flexibility and precariousness. Considering that the flexibility of the production process and working relations has a current flexible capitalism paradigm, that the familiar, informal and precarious labor force is a historical and constitutional status of this region and that there is a growing movement of overlap with the capitalist dynamics whose formalization processes are an expression, we ask: what is the meaning of formalization? From the formalization of enterprises, that is constituted as (new) standard in terms of labor relations? The central theoretical debate revolves around the concept of informal processes, by Maria Cristina Cacciamali (2000, 2011), which serve as ground for the discussion of new informality, which has been developed mainly by Angela Maria Carneiro Araújo (2011), Maria da Graça Druck (2011a) and Roberto Véras de Oliveira (2011/b). The methodological base is composed of semi-structured interviews, observation of production and dealing sites and data collection on secondary sources. From the analysis of the process of industrial enterprises formalization and with the resumption of transformations that this production cluster has passed through, we considerer that a pattern of formalization is consolidating: institutional formalization that engenders informal labor relations. In this sense, informality has been able to preserve, reproduce, and, above all, be re-signified by the action of entrepreneurs and through new methods of business management, such as business process outsourcing and subcontracting production in the context of the Complex, and it also finds a favorable and fertile atmosphere due to the "naturalization" of informal work.

Full textThis research initially presents the theory of complexity as a basis of understanding of complex adaptive systems, and the application of some variants of this theory such as fractal theory, in the field of strategic management in organizations. To achieve a better understanding of these approaches, the study has been divided into two stages: 1) Development and evolution of chaos and complexity in administration; 2) The Paradigm of dynamicity and application of the fractal approach in the field of business management and its study. The constant development of science and technology applied to the management and paradigm shifts presented throughout its evolution from the industrial revolution to the age of knowledge has led to the application of various scientific theories whose initial application was far from focusing on business management and which, however, has contributed to a better understanding of it. This is the case of the theory of fractality whose origin in abstract sciences resulting from the transition from classical geometry to fractal geometry. The contribution of the theory of complexity to facilitate the understanding of organizational phenomena will be shown; translating its application in the development of figures such as the “fractal factory- fractal organization” to support the debates of the science and technology of administration or its use as support for the design and construction of systems, subsystems, models, methods and procedures. It shows the evolution of the main theoretical contributions regarding the theory complexity, its bases or definitions, principles and applications and, finally, behavior as complex systems exposed in organizations.

Full text--- Peru, which is a rich country in amount of ores and gold reserves, moreover; it has an attractive minerals sector to the world and of great importance in national economic development. However, in the metallurgy of gold ores, there are minerals called refractory or complex, where free fine gold is trapped or associated with sulfides (pyrite and arsenopyrite), this problem can be seen in the concentrator Tamboraque, which uses inefficient conventional metallurgical processes and of high operating costs. Hence, the present research found an alternative treatment for this type of complex mineral, consisting in a total flotation in a first stage and then a special differential flotation in the second stage, obtaining as a result a reduction of 76.82 % treatment volume, 78.31 % the consumption of reagents, 63.64 % presence of toxic reactive in general tailings, 55.85 % and 55.04 % the volume of water and operating expenses used in flotation circuits in thereof. Furthermore, it was determined that a minimum investment of U.S. $ 406,160.73, this proposal can be implemented using only their own facilities and resource, generating an annual income of U.S. $ 222,486.01, and significant advantages in the environmental, technical and economic aspect.

Esta tese teve como objetivo geral analisar as articulações entre memória social e processos identitários no contexto de uma situação concreta de mudança sociocultural e econômica. A implantação do Complexo Portuário e Industrial de Suape, nas cidades do Cabo de Santo Agostinho e Ipojuca, no estado de Pernambuco, acarretou mudanças profundas no seu território, em termos ambientais, econômicos, sociais e culturais. A desterritorialização dos lugares tradicionais trouxe alterações nas relações de gênero, na sociabilidade e na reprodução da vida material. Em decorrência dessas mudanças, a população foi afetada também nas esferas da memória e da identidade. Para investigar estes processos, foram realizados dois Estudos, na cidade do Cabo, baseados teoricamente nas perspectivas que admitem que a memória e a identidade são construídas socialmente, nas relações entre os diferentes grupos e nas relações que os indivíduos ou grupos estabelecem com o seu meio material e simbólico, estando, pois, sujeitas a mudanças, estas, fruto de negociações, ajustes, esquecimentos, resistências e adesões. No primeiro estudo foi efetuada a descrição e a análise das relações grupais encontradas num processo em andamento no Cabo, que visa forjar uma memória compartilhada acerca das origens da cidade, sendo para tal proposta a narrativa de um mito fundador, o espanhol Pinzón. No Estudo 2 buscou-se apreender os conflitos e divergências gerados por posições grupais diferentes na sociedade e o impacto dessas mudanças geradas pela globalização representada pela Empresa Suape nos moradores das áreas ocupadas pela empresa e, mais especificamente, as transformações no registro da memória e da identidade desses sujeitos. No conjunto os estudos percebemos dinâmicas memoriais e identitárias heterogêneas, que apontam para variados efeitos de proximidade com o Complexo Suape, indo de uma adesão à narrativa hegemônica da globalização, processos de resistência e reconfigurações da memória e da identidade.
The overall objective of this thesis was to analyse the links between social memory and identity processes, in the concrete context of sociocultural and economic change. The implementation of the Complexo Portuário e Industrial de Suape, in the cities of Cabo de Santo Agostinho and Ipojuca, in the Brazilian, state of Pernambuco, led to profound environmental, economic, social and cultural changes in their territory. The deterritorialization of traditional lands caused transformations in gender relations, sociability and the reproduction of material life. As a result of these changes, the local population was also affected in the areas of memory and identity. In order to investigate these processes, two studies were conducted in the Cabo, theoretically grounded on perspectives that consider memory and identity to be socially constructed, on the relationships between different groups and on the relationships that individuals or groups establish with their material and symbolic environments. These perspectives are, therefore, subject to change due to new negotiations, adjustments, lapses in judgment, resistances and adherences. The first study endeavored to describe and analyse the ongoing group relations in the Cabo, which aims to forge a shared memory around the origins of the city through the narrative of a founding myth--the Spanish Pinzón. The second study sought to understand the conflicts and divergences resulting from different group positions in society, as well as the impact of changes brought about by globalization--represented by the Complexo Suape--on the residents of areas occupied by the Company and, more specifically, the transformations and changes in the memory and identity of these people. Through these studies, we have perceived heterogeneous memory and identity dynamics, which point to various effects of proximity with the Complexo Suaape, from adherence to a hegemonic globalization narrative, to processes of resistance and reconfigurations of memory and identity.

Full text-- This work presents the implementation of the recursion method proposed by Roger Haydock in the 80’s, for the calculation of the electronic density of states (DOS) projected on a specific atomic site (local DOS) of the system under study. This method does not solve the Schr¨odinger equation but the corresponding Green function. The main advantage of this method is that it can be applied to study large-size systems which are not possible with standard tools, as direct diagonalization of the Hamiltonian. To verify the performance of the method, I applied it to the calculation of the DOS of known systems such as finite linear chains, and finite square and cubic grids. After comparing the results employing the recursion and direct diagonalization methods a good agreement is found. To show tha relevance of the recursion method I studied the DOS of two different nanoscopic systems: copper nano-particles and finite graphene grids. In the first case I determined the threshold where the DOS of the copper nano-particles changes from a size-depending DOS to a typical DOS of the solid copper. The results indicate that the DOS of nano-particles of 2000 atoms; ie 3 nm diameter, do not present differences with the DOS of their solid counterparts. For the case of the finite graphene grids I studied the influence of the cutting edge on the DOS. The DOS of finite graphene grids of rhombic, triangular, square, ribbon and disc edge has been studied showing three kind of atoms with different local DOS: atoms with one, two and three first neighbours. In each finite grid the number of the surface atoms (with one and two first neighbours) changes producing different total DOS. The finite graphene grids that present minor influence of the surface are those of rhombic, hexagonal and ribbon edge type.

A study is made of the typology of architecture: housing, focused on social housing, and the elements necessary for residents and visitors to inhabit and enjoy the spaces that it can provide. In the process, different types of housing and strategies are compared, like national and international regulations. Likewise, various housing modules that meet the basic needs of the user were analyzed. Finally, the result of these studies is applied in the thesis Project resulting in a housing complex of social interest in the district of San Martin de Porres in the city of Lima. This, has as first approach the mixed use, a commercial base and housing towers. The Project, responds to the need for animation in the area and housing deficit, mentioned above. The second focus of the Project is at the level of meeting spaces that provide residents with leisure and common use areas, which complement daily activities and personal relationships, projecting flexible, versatile spaces in the various scales of the Project both in the common, social and private areas. As a result, a Project is achieved that revalues the urban space in which it is located and provides quality of life to its residents.

Full textThe project of the pisco tourism complex, located in the district of Lunahuana; in the province of Cañete, south of Lima, it is an architectural – landscape intervention. Whose objective is based on consolidating the local pisco route in addition to promoting activities in the area. So that the district achieves better development and the wineries begin to change their intervention scheme, considering that they are located in natural landscapes, which unfortunately are not considered in the design stage. This project involves a natural landscape; which is the Lunahuana valley, and it is studied to understand the relationships and interactions of this ecosystem in order to adapt without affecting its general composition. That is why the proposal seeks to create a link between the natural and the artificial. The propose is developed based on mimesis with the valley, respecting its characteristics and in the same cases even imitating them. Four volumes scattered on the land are developed, allowing them to be surrounded by nature and prioritizing the views on the valley at all times. The first volume develops, the reception, the production warehouse, the diffusion areas, the nursery and the service areas. The second volume is focused on the complementary areas of the complex and finally the rooms are located in the last two volumes. Finally, it is concluded that the proposal will help to promote and consolidate the activities in the area; allowing a better development of our flagship product, pisco.

Full textThe objective of this study was to evaluate the in situ effect of two commercial enzymes on the digestibility and kinetics of the dry matter sugarcane bud (Saccharum officinarum). The sugarcane bud was dried at 65°C for 48 hours, ground with a 3 mm sieve, and incubated for 30 minutes with the Allzyme Vegpro ® enzymes (T1), and the Rovabio Excel ® enzyme (T2). The enzymes were used at 1% of the body weight. The substrate without treatment was considered the control treatment (T0). It was used a randomized experimental design, with four periods, three treatments (T0, T1 and T2), and two replicates for treatment period. The samples were weighing (1.8 g), imputed in dracon bags and placed alpaca 1 compartment. The bags were removed after digestion in different hours (6, 12, 24, 48, 72, and 96), proceeding to the wash and then drying and weighing. The parameters evaluated in digestion kinetics were: initial digestibility, degradable fraction, degradation rate, potential digestion and average time. The results were analyzed using two-way ANOVA and Tukey's test is used to mean multiple differences. This study showed that digestibility in situ dry matter (ISDMD) did not improve. It was found only small differences (p<0.05) at 6, 12 and 48 hours but without biological significance. There were no differences among treatments (p>0.05) for initial digestibility, degradation rate, potential digestion and the average time, but there was difference (p<0.05) in the degradable fraction between T1 vs. T0 and T2. It is concluded that in the used dose fibrolytic enzymes do not increase digestibility or kinetics of digestion of the sugarcane bud (Saccharum officinarum). Key words: Enzyme fibrolytic, sugarcane bud, in situ digestibility, Alpaca

Full textThe Huaca Garagay Site Museum project, located in San Martín de Porres district, in Lima, is an architectural-urban intervention, whose purpose seeks to protect and reinforce the importance of an archaeological space abandoned, destroyed and invaded during its history, consolidating this sector in a metropolitan public space. By doing this, I integrate this sector with the city of Lima, but also, this project will create a community space for the residents of the area, seeking to protect the architectural monument already existing in the place. This project is based on theoretical bases, which means that have been developed on the research process, giving importance to the resources that have been taken in the last 20 years to harmoniously intervene in an archaeological site, resulting in a proposal that materializes in generating a link between Pre-Hispanic architecture and Contemporary Architecture. The proposal seeks a mimesis between what exists (the Huaca Garagay) and what is new (the Museum), generating one only building. On its first level, as an excavation, will have community spaces (library, workshops) that will allow recreation and rest in a "sunken plaza” central. The second level, which will be at street level, will have the development of the Site Museum and the Auditorium, and the last level, the restaurant. Everything connected to research, administration and services area. Finally, it is concluded that the proposal has a positive result in society, the city and the environment.

Full textThe Housing complex in the Rímac arises from the need to densify the city correctly and implement diverse and balanced spaces that contribute to the good social development of the inhabitants. One of the current concerns is urban densification lacking urban spaces for health, safety, leisure, and green areas. Therefore, this thesis seeks to present a model of set rooms that fulfills and rescues urban identity and customs, which have been altered over the last few years by focusing on real estate projects of limited capacity by excluding both urban equipment, social areas and green areas. The project adapts to the existing urban fabric through the arrangement of volumes that allow an adequate location without altering urban readability. Another important importance is that it rescues existing urban morphologies and housing typologies based on modern architecture that predominates in this sector of the Rímac. It also achieves social inclusion through the accessibility of all environments and the flexibility of housing adaptation for the disabled. Finally, a sustainable architectural design and construction system is applied through technological advances such as the use of cell concrete partitioning, high pressure compact sheet facade coating and conventional reinforced concrete construction system.
