Resumo: Analisa- se a biologia, epidemiologia e tratamento da infestação pelo Pediculus capitis,. discutindo a recrudecência rnundial, ocorrida a partir dos anos sessenta, suas possíveis causas e consequências. Para dimensionar sua ocorrência e estudar variáveis epidemioógicas: entre crianças brasileiras, examInaram-se 1596 pré-escolares da cidade de Paulínia, SP, no período de rmarço a julho de 1989. o coeficiente de prevalência da amostra foi de 35,75%, sendo de 27, 50 % entre as crianças do sexo masculino e de 43, 13% no sexo feminino (p0, 57) . A taxa de infestação não foi estatisticamente diferente entre os diversos comprimentos de cabelo, sendo de 33,30% nos: curtos, 39,44% nos médios e de 40,53 % nos longos (p > 0,03). Baseado na literatura e dados da investigação, conclui-se que a pediculosis capitis é um problema de saúde pública no Brasil, semelhante ao que ocorre em muitos outros países. Enfatiza-se a necessidade de se ter uma visão epidemológica da infestação, incorporando conceitos da interação parasita-hospedeiro, e se investir em tratamentos coletivos nas comunidades afetadas, para que possamos conseguir seu controle.
Abstract: The biology, epidemiology and treatment of Pediculus capitis infestation is reviewed, as well as the consequences and possible causes of its worldwide increase recognized in the sixties. A survey of 1696 preschool children was done in Paulínia, SP, Brazil, from March to July 1989. The prevalence coeficient of the sample 'was 35, 75% - 27,60% in boys and 43,13% in girls (pO,57). There are no significant difference in regard to hair length - 33,30% among those, with long hair, 39,44% with median and 40,53% w'ith short hair (p>O,03) . The results of the survey and a review of current and past literature, lead to the conclusion that pediculosis capitis as a public health problem In Brazil is similar to other countries, industrialized or not. Emphasis 1S given to an epidemiological understanding of the infestation and the need of colletive approaches to treatment as the only way to attain its control.

Resumo: A pediculose, doença causada pelo artrópode Pediculus humanus capitis é considerada um problema de saúde pública, pois afeta milhões de pessoas em todo o mundo, no entanto, crianças em idade escolar são as mais acometidas. É de conhecimento popular que alguns indivíduos são mais suscetíveis à parasitose que outros, porém, fatores inerentes ao hospedeiro, que podem influenciar na suscetibilidade à essa doença não estão totalmente esclarecidos. Assim, o objetivo do presente estudo foi isolar e identificar a microbiota do couro cabeludo e analisar se determinadas caracteríscas da morfologia do cabelo (tipo, cor, comprimento, escamas e diâmetro) podem interferir na predisposição à doença. Para a análise da microbiota do couro cabeludo, 10 crianças com pediculose (grupo A) e 10 crianças sem pediculose (grupo B) foram analisadas. As amostras da microbiota do couro cabeludo foram coletadas através de swabs que foram friccionados na cabeça e acondicionados em meios de transporte Stuart. O isolamento da microbiota fúngica foi feito em Ágar Sabouraud (SBA) com tetraciclina e o isolamento bacteriano foi feito em ágar sangue. A identificação molecular foi realizada através de sequenciamento da região 16S e ITS do DNA ribossomal bacteriano e fúngico, respectivamente. Um total de 186 isolados foram obtidos sendo 35 bactérias e 40 fungos (grupo A) e 47 bactérias e 64 fungos (grupo B). Os resultados sugerem que a microbiota isolada pode estar envolvida na suscetibilidade à pediculose. Em relação à microbiota bacteriana, no grupo A, Staphylococcus captis foi significativamente diferente (P<0.01) em relação Sthaphylococcus epidermidis presente no grupo B. Dentre os fungos isolados, foi observado que Debaryomyces sp. foi o fungo mais frequente (15,6%) no grupo B e (2,5%) no grupo A (P<0.01). No grupo B, ocorreu uma maior diversidade em relação ao grupo A. Essa diversidade foi demonstrada pela presença de bactérias como Staphylococcus hominis (2,1%), Klebsiella oxytoca (4,2%), Pseudomonas stutzeri (4,2%), Acinetobacter nosocomialis (2,1%), e Bacillus muralis (4,2%), enquanto que no grupo A, apenas Pseudomonas sp. (5,7%) e Phychrobacter sp. (2,8%) foram encontrados. Desta forma, acredita-se que a diversidade da microbiota do couro cabeludo pode interferir na preferência do piolho. Em relação às análises das características dos fios de cabelo, das 154 crianças analisadas, através da regressão logística multivariada, O cabelo encaracolado é aquele que apresenta o maior risco de pediculose, quando comparado com o gênero, idade e cabelos longos. O cabelo escuro também está associado ao risco de pediculose. Acredita-se que que a cor escura facilitaria a camuflagem de piolhos em cabelos escuros. Assim, meninas de cabelo comprido, escuro, encaracolado, escamas estreitas e diâmetro do fio de cabelo menor apresentaram maior risco para a pediculose. Referente a prevalência de piolhos, das 658 crianças (338 meninas e 320 meninos) analisadas, as meninas estavam mais infestadas (54,1%) que meninos (36,8%) (P> 0,05). No entanto, quando comparado os grupos etários, meninos com idades de 2-3 anos estavam mais infestados que as meninas. Palavras-chave: Piolho; cabelo; bactérias; fungos e prevalência.
Abstract:Pediculosis, a disease caused by the arthropod Pediculus humanus capitis is considered a public health problem as it affects millions of people around the world. However, school children are the most affected. It is popular knowledge that some individuals are more susceptible to parasitosis than others, but factors inherent to the host that may influence the susceptibility to this disease are not well understood. In this context, the objective of the present study was to isolate and identify the scalp microbiota and to analyze if certain characteristics of hair morphology (scales, type, color, length and diameter) may interfere with predisposition to the disease. For analysis of the scalp microbiota, 10 children with pediculosis (group A) with 10 children without pediculosis (group B) were analyzed. Samples of the scalp microbiota were collected through swabs that were rubbed on the children's heads and packed into Stuart transport medium. Isolation of the fungal microbiota was done in Sabouraud Agar (SBA) with tetracycline and bacterial isolation was done on blood agar. Sequencing was done for the 16S and 18S region of the bacterial and fungal ribosomal DNA, respectively. A total of 186 isolates were obtained from group A, from these 35 bacteria and 40 fungi and for group B, 47 bacteria and 64 fungi were isolated. The results suggest that the isolated microbiota may be involved in pediculosis susceptibility. In relation to the bacterial microbiota, in group A, Staphylococcus capitis was significantly different (p <0.01) in relation to Staphylococcus epidermidis present in group B. Among the isolated fungi, it was observed that Debaryomyces sp. was the most frequent fungus (15.6%) in group B and (2.5%) in group A (p <0.01). In group B occurred in a higher diversity in relation to group A, demonstrated by the presence of bacteria such as Staphylococcus hominis (2.1%), Klebsiella oxytoca (4.2%), Pseudomonas stutzeri (4.2%), Acinetobacter nosocomialis (2.1%), and Bacillus muralis (4,2%), while in group A only Pseudomonas sp. (5.7%) and Phychrobacter sp. (2.8%) were found. Thus, it is believed that the diversity of the scalp microbiota may interfere with the preference of the lice. Regarding the analyzes of hair characteristics by multivariate logistic regression, of the 154 children analyzed, the curly hair is the one that presents the highest pediculosis risk, even exceeding the gender and age. In this study, it was observed that dark hair is also associated with the risk of pediculosis. It is believed that a higher percentage of dark-colored lice would facilitate the camouflage of dark-colored lice. So, girls with long, dark, curly hair, narrow scales and smaller hair diameter presented greater risk for pediculosis. Regard to the prevalence of lice, of the 658 children (338 girls and 320 boys) analyzed, the girls were more infested (54.1%) than boys (36.8%) (P> 0.05). However, when compared to age groups, boys aged 2-3 years were more infested than girls. Keywords: Head lice; hair; bacterium; fungi and prevalence

Resumo: Baccharis milleflora (Less.) DC. popularmente conhecida como carqueja, carqueja do lajeado, possui poucos estudos registrados na literatura. É utilizada na medicina popular como diurética e estomáquica. O objetivo desse trabalho foi realizar a análise morfoanatômica, caracterizar o óleo essencial (OE) e avaliar as atividades antioxidante, antimicrobiana, pediculicida, citotóxica e imunomoduladora. Por meio de microscopia óptica e de microscopia eletrônica de varredura foram evidenciados estômatos anomocíticos e actinocíticos, tricomas glandulares capitados bisseriados, tectores flageliformes simples e dutos secretores de produtos lipofílicos. Os compostos majoritários identificados por CG/EM nas quatro estações do ano foram: trans-cariofileno, ?-humuleno, germacreno D e o biciclogermacreno. A atividade antioxidante pelo método DPPH apresentou IC50 entre 15,45 ?g/mL - 21,06 ?g/mL e pelo método ABTS IC50 entre 3,85 ?g/mL - 4,60 ?g/mL. A atividade antioxidante pelo fosfomolibdênio foi de 77,9% a 79,81%. O índice antioxidante pelo TBARS variou de 12,60% a 29,06%. Foi verificada atividade frente a S. aureus nas quatro estações por microdiluição em caldo. A atividade pediculida apresentou um IR de 80,65% e um KT50 de 10,63 min. O OE apresentou citotoxicidade frente às linhagens Jurkat, Raji e HL-60 pelo ensaio de redução do brometo de 3-(4,5-dimetil-tiazol-2-il)-2,5- difenil-tetrazólio (MTT) e inibiu a proliferação celular (30 e 100 ?g/mL) por afetar o conteúdo de DNA. A 10 ?g/mL diminuiu significativamente o conteúdo de DNA nas três linhagens tumorais mediante o ensaio com o iodeto de propídeo. O óleo essencial a 60 ?g/mL gerou parada em G0/G1 com uma diminuição no número de células nas fases S e G2/M. A coloração com EB/AO e Hoechst 33342 demonstrou que o OE provoca a morte celular por mecanismos de necrose e apoptose. O índice de seletividade de 3,97 obtido reforça a seletividade deste óleo frente às células malignas Raji. Frente às células J774 o óleo essencial (30 e 100 ?g/mL) apresentou moderado efeito citotóxico pelo ensaio do MTT e da sulforodamina com valores de IC50 independentes do tempo de exposição. As células J774 incubadas com OE (8 ?g/mL) apresentaram uma redução estatisticamente significativa na produção de óxido nítrico. A 10 e 20 ?g/mL o OE não inibiu a produção de espécies reativas de oxigênio nos tempos avaliados. A capacidade fagocítica do OE utilizando partículas não opsonizadas de zimozan foi de aproximadamente 40%, sugerindo atividade imunomoduladora. Palavras-chave: Antioxidante. Baccharis milleflora. Cultura celular. Óleo essencial. Pediculicida.
Abstract: Baccharis milleflora (Less.) DC. popularly known as carqueja, carqueja do lajeado, has few studies registered in the literature. It is used in folk medicine as diuretic and stomatal. The objective of this work was to perform the morphoanatomic analysis, to characterize the essential oil (EO) and to evaluate the antioxidant, antimicrobial, pediculida, cytotoxic and immunomodulatory activities. Scanning electron microscopy and optical microscopy revealed anomocytic and actinocytic stomata, bisserial capillary glandular trichomes, simple flagelliform tectonics and secretory ducts of lipophilic products. The major compounds identified by GC/MS in the four seasons were: trans-caryophyllene, ?-humulene, germacrene D and bicyclogermacrene. The antioxidant activity by the DPPH method presented IC50 between 15.45 ?g/mL - 21.06 ?g/mL and by ABTS method IC50 between 3.85 ?g/mL - 4.60 ?g/mL. The antioxidant activity by fosfomolibdenium was 77.9% to 79.81%. The antioxidant index by TBARS ranged from 12.60% to 29.06%. Activity against S. aureus was verified in the four seasons by broth microdilution. The repellent activity had an repellency index of 80.65% and a KT50 of 10.63 min. Essential oil showed cytotoxicity against the Jurkat, Raji and HL-60 cells by the MTT assay and inhibited cell proliferation (30 and 100 ?g/mL) for affecting the DNA content. At 10 ?g/mL significantly decreased the DNA content in the three tumor lines by the propidium iodide assay. The essential oil at 60 ?g/mL generated a G0/G1 arrest with a decrease in the number of cells in the S and G2/M phases. The staining with EB/AO and Hoechst 33342 demonstrated that EO causes cell death by mechanisms of necrosis and apoptosis. The selectivity index of 3.97 obtained reinforces the selectivity of this oil against the Raji malignant cells. The EO (30 and 100 ?g/mL) presented a moderate cytotoxic effect in J744 cells by the MTT and SRD assay with IC50 values independent of the exposure time. J774 cells incubated with EO (8 ?g/mL) showed a statistically significant reduction in nitric oxide production. At 10 and 20 ?g/mL EO did not inhibit oxigen-reactive species production at the times evaluated. The phagocytic capacity of EO using nonopsonized zimozan particles was approximately 40%, suggesting immunomodulatory activity. Key-words: Antioxidant. Baccharis milleflora. Cell culture. Essential oil. Pediculicide.

Este trabalho foi desenvolvido com 35 escolas do Município de Itaboraí/RJ em parceria com o Departamento de Biologia do Instituto Oswaldo Cruz/FIOCRUZ-RJ e Secretaria Municipal de Educação, respaldada em estratégias que visam a articulação entre a Formação Continuada de Professores e Pesquisa Qualitativa em Educação. Para coleta de dados foi utilizada a Pesquisa Documental do tipo técnico e pessoal. Para a análise e interpretação dos dados e conteúdos presentes nas falas das educadoras e nos documentos construídos durante a Formação, buscamos suporte na Análise de Conteúdo e Análise Descritiva. O trabalho tem como eixo temático na área de Biociências e Saúde, o tema piolho/pediculose, numa perspectiva de Educação em Saúde e de Educação para a Saúde, preconizadas nos Parâmetros Curriculares Nacionais (PCN): Temas Transversais – Meio Ambiente e Saúde, objetivando a construção conjunta de estratégias educacionais participativas, por meio das educadoras participantes da Formação Continuada em Pediculose: Quando o Piolho Invade a Aula e o (a) Professor (a) afasta o aluno. Após a Formação Continuada, as educadoras implementaram em suas Unidades Escolares Projetos Pedagógicos, ações pontuais ou ações continuadas sobre piolho/pediculose visando à saúde das crianças, importância do uso diário do pente fino como forma de prevenção a pediculose e alternativa não medicamentosa para o controle dessa ectoparasitose causada pela infestação por piolhos e lêndeas. A Formação Continuada pretendeu no ano de 2004, dar continuidade ao processo de Formação iniciado em 2003 e aos projetos iniciados e/ou discutidos. No todo, a Formação, atendeu 50 professoras/educadoras, representando na sua totalidade 35 escolas, nas modalidades de Creche, Educação Infantil a 4a série, Educação Infantil a 8a série, 1a a 4a série e 1a a 8a série. Como resultado da Formação Continuada, 10 escolas implementaram projetos pedagógicos e 9 apontam para a diminuição de alunos (as) infestados (as) por piolhos, 14 escolas desenvolveram ações pontuais e/ou ações continuadas conforme as suas demandas e necessidades e 13 afirmaram ter diminuído o número de alunos e alunas parasitados (as); 11 escolas não desenvolveram qualquer tipo de ação educativa. Os resultados alcançados são animadores, pois, sinalizam que o fazer pedagógico voltado para ações educativas alicerçadas na saúde e na sua construção pessoal e coletiva, contribui para a aquisição e o compartilhamento de informações mais corretas, para o processo de construção do conhecimento gerando mudanças de hábitos e atitudes na comunidade escolar, devido à compreensão da necessidade dos cuidados com a parasitose e, oportunizando o processo de construção e internalização do conhecimento construído e pronto a ser socializado. Essas ações educativas são de suma importância, pois, levam a uma diminuição da incidência e prevalência frente a essa morbidade que, no senso comum, oportuniza o exercício do preconceito, da discriminação, do agravamento da pediculose e do aparecimento de doenças físicas, doenças sociais, doenças emocionais, tais como, as miíases e o impetigo, a exclusão do convívio por outros (as) escolares, o constrangimento, apelidos pejorativos, o bullyng, a baixa-estima e dificuldades de aprendizagem.
This study was developed in 35 schools of the municipal district of Itaboraí/RJ in partnership with the Biology Department of the Oswaldo Cruz Institute/FIOCRUZ-RJ and Municipal Educational Department, based on strategies that aim the link between Teachers’ Continued Formation and Qualitative Research in Education. To collect these data a technical and personal documental research was used. To the analysis and interpretation of the data and contents present in the speech of the educators and in the documents built during the Formation, we looked for support in the Contents Analysis and Descriptive Analysis. The study is centered in the area of Bioscience and Health, the theme lice/pediculosis, in a prospective of Health Education and Education for Health, preconized in the National Curricular Parameters (PCN): Transversal Themes – Environment and Health, having the goal to build participative educational strategies altogether, by means of teachers/educators who took part in the Pediculosis Continued Formation: When The Louse Invades The Class And The Teacher Repels The Student. After the Continued Formation, educators implemented pedagogical projects in their schools, through sharp actions or continued actions about lice/pediculosis, viewing the children’s health and the importance of the daily use of toothcombs as a way of preventing pediculosis and non-medicamental alternative to the control of this ectoparasitosis caused by lice and nits infestation. The Continued Formation wished, in 2004, to continue the Process of Formation begun in 2003 and the projects already started and discussed. On the whole, the Formation, attended 50 educators, representing a total of 35 schools, such as nursery school, kindergarten, primary school and elementary school. As a result of the Continued Formation, 10 schools implemented pedagogical projects and 9 pointed out to a decrease of lice infested students, 14 schools developed sharp actions and/or continued actions according to their demands and necessities and 13 assumed to have diminished the number of infested students; 11 schools did not develop any kind of educational action. The results obtained are encouraging, because they demonstrate that the pedagogical managements directed to educational actions based on health and in its personal and collective construction, contribute to the acquisition and the sharing of correct information, to the process of the building knowledge causing changes in habits and attitudes in the schools community, due to the comprehension of the necessity of the care with parasitosis and promote the building process, and the internalization of the acquired knowledge ready to be socialized. These educational actions are very important, because they lead to the decrease of the incidence and prevalence of this morbidity that, in common sense, collaborate to prejudice, discrimination, pediculosis aggravation and the uprising of physical, social and emotional diseases, such as myiasis and impetigo, the social contact exclusion by other scholars, the coercion, the pejorative nicknames, the bullying, the low esteem and the learning difficulties.

Small wild mammals, including rodents and marsupials, have ecological and epidemiological importance for being prey and predators in ecological chains, hosts of ecto and endoparasites and pathogens reservoirs. In Northeast Brazil, only a few studies have evaluated the diversity of ectoparasites and their hosts in the Caatinga biome. This study aimed to identify the hosts and their ectoparasites, with morphometric analysis and chaetotaxy and to determine the rates of parasitic Prevalence, Abundance and Medium Intensity of ectoparasites collected from rodents and marsupials, proceeding from the Experimental Station Rafael Fernandes, Rio Grande do Norte, Brazil, at the Universidade Federal Rural do Semi-Árido (UFERSA). The animals were captured between January 2014 and February 2015, in a fragment of 26 hectares, divided into six equally spaced transects (20m). Tomahawk and Sherman traps were distributed in six consecutive nights of each month and in 100 capture stations. The captured animals were identified by morphology and submitted to ectoparasites collection. All the collected ectoparasites were classified based on morphometric characters, chaetotaxy and taxonomic keys, as well as DNA extraction, PCR and sequencing of the amplified products. 78 small mammals were captured, from which 69 were classified as Didelphimorphia order: Gracilinanus agilis (Burmeister, 1854) and Monodelphis domestica (Wagner, 1842); and nine Rodentia: Wiedomys Hershkovitz, 1959, Thrichomys Trouessart, 1880 and Rattus norvegicus Berkenhout, 1769. It was collected ectoparasites identified as: Amblyomma (Koch, 1844), Amblyomma parvum, Aragão 1908, Amblyomma auricularium (Conil, 1878), Ornithodoros mimon Kohls, Clifford e Jones 1969, Ornithodoros Kohls, Clifford e Jones 1837, Quadraseta Brennan, 1970, Eutrombicula Ewing, 1938, Metachiroecius Fain, 1996, Aeromychirus Fain, 1976, Amlistrophorus Fain, 1981, Radfordia Ewing, 1938, Listropsoralges aff. similis, Ornithonyssus pereirai (Fonseca, 1935), Tur lativentralis (Fonseca 1936), Polyplax spinulosa (Burmeister, 1839) and Eogyropus lenti lenti (Werneck 1936). As for the parasitic rates were noted that for the Ixodidae and Argasidae studied, M. domestica presented higher parasitism values for A. auricularium; G. agilis, O. mimon and Thrichomys sp., to A. parvum and A. auricularium. As for mites, the prevalence was the same in M. domestica and to all its studied Listrophoridae. Also for rodents, it was observerd the same prevalence rate for Laelapidae mites and Polyplacidae lice in the Thrichomys sp. All of those records of small mammals and ectoparasites shown are unprecedented to Mossoró, Rio Grande do Norte. This study supports evidences from the literature that ectoparasites use marsupials and wild rodents as hosts for immature stages. Justifies the importance of maintaining a legal reserve area in the Caatinga biome for preservation of these animals. In addition, this research increases knowledge about the occurrence of Acari, Phthiraptera and its ectoparasitic association with the wildlife in Northeast Brazil
Os pequenos mamíferos silvestres, dentre eles os roedores e marsupiais, apresentam importância ecológica e epidemiológica por serem presas e predadores nas cadeias ecológicas, hospedeiros de ecto e endoparasitos e reservatórios de agentes patogênicos. No Nordeste do Brasil, poucos estudos avaliaram a diversidade de ectoparasitos e seus hospedeiros no bioma Caatinga. Objetivou-se identificar os hospedeiros e seus ectoparasitos, realizar morfometria e quetotaxia e determinar os índices parasitários de Prevalência, Abundância e Intensidade Média dos ectoparasitos coletados de roedores e marsupiais, procedentes da Estação Experimental Rafael Fernandes da Universidade Federal Rural do Semi-Árido (UFERSA). Capturou-se animais de janeiro de 2014 a fevereiro de 2015, em um fragmento de 26 hectares da Estação, divididos em seis transectos equidistantes (20m). Foram distribuídas armadilhas Tomahawk e Sherman em seis noites consecutivas de cada mês e em cem estações de captura. Os animais capturados foram identificados pela morfologia e submetidos à coleta dos ectoparasitos. Estes foram classificados com base em caracteres morfométricos, quetotaxia e chaves taxonômicas, além de extração de DNA, PCR e sequenciamento dos produtos amplificados. Foram capturados 78 pequenos mamíferos, dos quais 69 foram classificados na ordem Didelphimorphia: Gracilinanus agilis (Burmeister, 1854) e Monodelphis domestica (Wagner, 1842); e nove Rodentia: Wiedomys Hershkovitz, 1959, Thrichomys Trouessart, 1880 e Rattus norvegicus Berkenhout, 1769. Coletou-se ectoparasitos identificados como: Amblyomma (Koch, 1844), Amblyomma parvum Aragão, 1908, Amblyomma auricularium (Conil, 1878), Ornithodoros mimon Kohls, Clifford e Jones, 1969, Ornithodoros Kohls, Clifford e Jones 1837, Quadraseta Brennan, 1970, Eutrombicula Ewing, 1938, Metachiroecius Fain, 1996, Aeromychirus Fain, 1976, Amlistrophorus Fain, 1981, Radfordia Ewing, 1938, Listropsoralges aff. similis, Ornithonyssus pereirai (Fonseca, 1935), Tur lativentralis (Fonseca 1936), Polyplax spinulosa (Burmeister, 1839) e Eogyropus lenti lenti Werneck 1936. Quanto aos índices parasitários, observou-se que para os Ixodidae e Argasidae estudados, M. domestica apresentou maiores valores de parasitismo para A. auricularium; G. agilis, para O. mimon e Thrichomys sp., para A. parvum e A. auricularium. Quanto aos ácaros, a prevalência foi igual em M. domestica e para todos os seus Listrophoridae estudados. Igualmente, para os roedores, observou-se mesmo valor de prevalência para os ácaros Laelapidae e para os piolhos Polyplacidae em Thrichomys sp. Todos os registros dos pequenos mamíferos e ectoparasitos apresentados são inéditos para Mossoró, Rio Grande do Norte. Este estudo corrobora evidências da literatura dos ectoparasitos utilizarem marsupiais e roedores silvestres como hospedeiros em fases imaturas. Justifica a importância da manutenção de uma área de reserva legal no bioma Caatinga para conservação destes animais. Em adição, a presente pesquisa aumenta o conhecimento sobre ocorrência de Acari, Phthiraptera e sua associação ectoparasitária de vida selvagem, no Nordeste do Brasil

A bionomia de Chelopistes meleagridis fora do hospedeiro foi observada com o objetivo de compreender aspectos relacionados ao ciclo de vida desta espécie. Para isto, adultos de C. meleagridis foram coletados e colocados em condições controladas para se reproduzir, oferecendo-se pena como alimento. Da prole destes adultos, foi observado o desenvolvimento de 150 indivíduos desde o ovo até a fase adulta. Para 75 destes, foi oferecida a dieta composta de pena, enquanto para os outros 75 a dieta foi composta de pena e pele do hospedeiro (peru, Meleagris gallopavo). Ao verificar que a dieta “pena + pele” foi a que resultou no maior número de adultos, foram observadas a fertilidade, fecundidade e a longevidade de piolhos criados in vitro desde o primeiro ínstar alimentados com esta dieta. Valores altos relacionados à reprodução desta espécie foram encontrados em relação a outros piolhos da subordem Ischnocera, destacando-se: número de ovos produzidos por dia e número de ovos produzidos por fêmeas durante a vida (médias de 2,54 e 26,61 ovos, respectivamente, para fêmeas selvagens e 2,11 e 29,33 ovos, respectivamente, para fêmeas criadas in vitro.). A inclusão de pele na dieta foi determinante para o desenvolvimento até o estágio adulto, uma vez que 48% dos piolhos alimentados com essa dieta atingiram a fase adulta. Quando foi oferecido apenas pena, 1,3% dos piolhos atingiram a maturidade. O tempo de desenvolvimento de machos e fêmeas foi semelhante (média de 29,38 dias) sem haver diferença na proporção sexual dos adultos.
Bionomics of the large louse turkey Chelopistes meleagridis off host was evaluated to comprehend aspects related to life cycle. To this, adults was collected and put in controlled conditions for reproduce, offered feathers as food. From offspring of these adults were observed the development of 150 lice from eggs to adults. To 75 of them was given only feathers as resource of food while to others 75 lice the diet was composed by feathers and skin debris from the natural host, Meleagris gallopavo. When verified that diet composed by feather + skin resulted in more adults, was evaluated fertility, fecundity and longevity of this specie reared in vitro from first nymphs to adults feed with this diet. High values related to reproduction of this specie were found in comparison with others avian Ischnocera, like: number of eggs produced by day and number of egg produced during the lifespan of females (means of 2.54 and 26.61, respectively to wild females and 2.11 and 29.33 respectively to females reared in vitro). The addition of skin in diet was determinant to development to adult stage, once time 48% fed with this diet reared to adults while the lice feed with feathers only 1.3 % of then became adult stage. The time of development of males and females was the same (29 days). The sex rate of adults reared in vitro was 1:1.

Apesar da grande diversidade de aves silvestres no Brasil, poucos são os estudos sobre seus ectoparasitos. Informações sobre as espécies de piolhos mastigadores (Phthiraptera: Amblycera e Ischnocera) que ocorrem em sanhaçu-cinzento (Tangara sayaca) e aves do gênero Turdus são escassas, o que dificulta compreender a relação parasitária entre esses animais.Dessa forma, no primeiro capítulo, objetivou-se verificar a presença de piolhos em T. sayaca em diferentes fragmentos de Mata na Zona da Mata de Minas gerais. Foram coletados 39 indivíduos de T. sayaca, sendo que destes 25 (64,10%) estavam parasitados por piolhos. Brueeliasayacae foi relatada pela primeira vez em T. sayaca no Brasil, enquanto Ricinussubangulatus e Machaerilaemustangarae foram registrados pela primeira vez em T. sayaca. Além destes novos relatos, a espécie Myrsideaseminuda também foi encontrada em T. sayaca, sendo este o segundo relato desta associação no Brasil. Já o segundo capitulo teve como objetivo identificar os piolhos das aves do gênero Turdus capturadas no Jardim Botânico da Universidade Federal de Juiz de Fora, Juiz de Fora, Minas Gerais, bem como analisar a dinâmica da estrutura populacional destes parasitos durante estações seca e chuvosa. As aves foram capturadas entre os meses de março de 2013 a dezembro de 2015, por redes de neblina. Foram capturadas quatro espécies do gênero Turdus: Turdusalbicollis, Turdusflavipes, Turdusleucomelas e Turdusrufiventristotalizando 146 indivíduos, das quais 77 estavam parasitados por piolhos. Cinco espécies de Phthiraptera foram encontradas: Brueeliasp.,Sturnidoecussarwatae, Sturnidoecusrehanae, Myrsidearegius e Menacanthuseurysternus, totalizando 1023 espécimes coletados. Turdusrufiventris foi a espécie com o maior número de indivíduos capturados. M. regius representa o primeiro registro parasitário para T. rufiventrise é o primeiro relato no Brasil. S. sarwatae representa o primeiro registro parasitário para T. lecomelas e T. albicollis no Brasil. Para T. flavipes, as três espécies de piolhos aqui encontradas são registros novos de parasitismo. S.rehanae além de ser um novo registro de hospedeiro em T. flavipes, é o primeiro relato no Brasil. O presente trabalho amplia o conhecimento geográfico destes parasitos e mostra a sua dinâmica parasitária em aves silvestres em fragmentos de Mata Atlântica em Minas Gerais.
Despite the great diversity of wild birds in Brazil, there are few studies on their ectoparasites. Information on chewing lice species (Phthiraptera: Amblycera andIschnocera) occurring on the tanager (Tangarasayaca) and thrushes (Turdus genus) are scarce, hindering the comprehension of the parasitary relations of these animals. On this sense, in the first chapter, we aimed to verify the presence of louse in T. sayaca in different forest fragments in Zona da Mata, Minas Gerais state. We collected 39 T. sayacaindividuals, and 25 of these were parasitized by louse (64.10%). Brueeliasayacaewas recorded for the first time in T. sayacain Brazil, while Ricinussubangulatus andMachaerilaemustangaraewere related for the first time on the species. Aside from these new records, the species Myrsideaseminuda was also found on T. sayaca, making it the second record for this association in Brazil. In the second chapter, our goal was to identify the louse on birds of the Turdusgenus captured at the Botanic Garden of Federal University of Juiz de Fora in Juiz de Fora, Minas Gerais state, and to analyze the population dynamics of such parasites during the dry and the rainy seasons. Birds were captured between the March 2013 and December 2015 through mist nets. Four species of Turdus were captured: Turdusalbicolis,Turdusflavipes, Turdusleucomelas andTurdusrufiventris, totaling 146 individuals, of which 77 were parasitized by louse. Five species of Phthiapterawere found: Brueelia sp.,Sturnidoecussarwatae, Sturnidoecusrehanae, Myrsidearegiusand Menacanthuseurysternus, totaling 1023 sampled specimens. Turdusrufiventris was the species the highest number of captured individuals. Myrsidearegius represents the first parasitary record for T. lecomelas and T. albicolis in Brazil. For T. flavipes, all three species of lice found in our study are new parasitary records. Sturnidoecusrehanae is not only a first host record in T. flavipes but also a first record in Brazil. Our work widens the parasites’ known geographic distribution and shows their parasitary dynamic in wild birds in Atlantic Forest fragments in Minas Gerais.

Abstract:
Gli anni di piombo sono un periodo storico che ha lasciato una traccia indelebile nella società italiana. La presente tesi è un`analisi del modo in cui gli eventi degli anni di piombo vengono rappresentati e riproposti nella cinematografia prodotta nei quarant`anni successivi. Nell`analizzare una così vasta ed eterogenea filmografia si é cercato di individuare l`esistenza di una tendenza di carattere generale che fosse comune alla maggioranza delle pellicole prodotte sull`argomento, in modo da rivelare che tipo di correlazione esiste tra i film analizzati ed il contesto storico, sociale e culturale in cui sono stati prodotti. I film analizzati sono stati raggruppati in tre aree tematiche riguardanti, rispettivamente, i film dedicati al terrorismo di sinistra, quelli dedicati al terrorismo di destra e, infine, la cinematografia che affronta l`eredità lasciata dagli eventi degli anni di piombo sulla società italiana. Nel corso di tale analisi, ciò che è emerso è una produzione cinematografica che risulta estremamente sintomatica del contesto storico e culturale entro il quale è stata prodotta. I film in esame, tutti, seppur in modalità estremamente differenti, alle prese con la ricerca di quel superamento del trauma che gli eventi degli anni di piombo avevano causato, risultano infatti sintomatici delle circostanze storiche e culturali in cui sono emersi: si tratta, quindi, di un corpus cinematografico che rappresenta eventi, circostanze e sentimenti che sono tutti profondamente ancorati nel proprio contesto storico e culturale.

A possibilidade de produzir etanol de resíduos lignocelulósicos tem se tornado cada vez mais atrativo. Dentre os diferentes tipos de resíduos o piolho de algodão gerado na indústria têxtil e a palha de cana de açúcar proveniente das lavouras de cana de açucar podem ser uma alternativa viável em processos fermentativos para a produção do bioetanol. Clostridium thermocellum possui alta capacidade de hidrólise de diferentes biomassas pela presença do complexo multienzimáticocelulossoma. O objetivo deste trabalho foi caracterizar as melhores condições de cultivo de C. thermocellum isolado (B8), obtido a partir do material do rúmen de caprino da raça Moxotó e mapear as proteínas secretadas na presença de piolho de algodão, palha de cana de açúcar e celulose cristalina, além de avaliar a expressão de alguns genes envolvidos na formação do complexo celulossomal. C. thermocellum B8 apresentou melhor condição de crescimento a 60°C, pH 7,0 e após 48 horas de incubação. Nas amostras do sobrenadante da cultura e nas frações eluídas dos susbtratos residuais: celulose (FEC), piolho de algodão (FEP) e palha de cana (FEPA) foi registrada atividade enzimática de Avicelase, CMCase, FPase e Xilanase. A taxa de expressão de genes quantificados por RT-qPCR, envolvidos na formação do celulossoma mostrou diferentes perfis de expressão em relação ao tempo de cultivo e ao tipo de substrato utilizado. A espectrometria por meio de nanoUPLC-MSE foi capaz de identificar 80 proteínas nas frações eluídas dos substratos residuais sendo que destas 32 em FEC, 25 em FEP e 23 em FEPA. Estavam presentes proteínas responsáveis pela formação da estrutura do celulossoma, proteínas do metabolismo de carboidratos, proteínas estruturais, de transporte de solventes e íons e de defesa. Os resultados apresentados podem ajudar a conceber estratégias para a otimização do cultivo de C. thermocellumB8em piolho algodão e palha de cana em grande escala para a hidrólise enzimática desses resíduos e possível produção de etanol.
The possibility of producing ethanol from lignocellulosic waste has become increasingly attractive. Among the different types of waste cotton louse generated in the textile industry and sugar cane straw from the sugar cane fields can be a viable alternative fermentation processes for the production of bioethanol. Clostridium thermocellum has high capacity hydrolysis of biomass by different complex multienzymaticcellulosome presence. The objective of this study was to characterize the best growing conditions of C. thermocellum isolated B8, obtained from Moxotó of goat rumen materials and map the proteins secreted in the presence of cotton louse, sugarcane straw and crystalline cellulose, and to evaluate the expression of genes involved in the formation of celulossomal complex. C. thermocellumB8 showed better growth condition of 60° C, pH 7.0 and after 48 hours of incubation. Samples of the culture supernatant, and eluted in the fractions of residual susbtratos: celullose (FEC), cotton louse (FEP), and sugarcane straw (FEPA) was recorded enzymatic activity of Avicelase, CMCase, and FPaseXylanase. The level of gene expression quantified by RT-qPCR involved in the formation of cellulosome showed different profiles of expression in relation to culture time and the type of substrate used. The spectrometry using nanoUPLC-MSE was able to identify 80 the proteins eluted fractions of residual substrates among these FEC 32, FEP 25 and 23 FEPA. Were present proteins responsible for the formation of cellulosome structure, carbohydrate metabolism of proteins, structural proteins, transport of ions and solvents and defense. These results can help develop strategies to optimize the cultivation of C. thermocellum B8 cotton louse and sugarcane straw on a large scale for the enzymatic hydrolysis of these residues and possible production of ethanol.

Abstract:
Fino a pochi anni fa l’economia dei paesi più sviluppati non teneva in nessun conto l’esauribilità delle risorse del pianeta. La crescita dei paesi cosiddetti emergenti ci ha messo di fronte ad un problema enorme: ciò che la terra produce non è più sufficiente per i consumi di tutti. In particolare è aumentato a dismisura il fabbisogno energetico di questi paesi: per soddisfarlo ogni risorsa viene utilizzata senza tenere conto degli effetti inquinanti. Si cominciano già a vederne i primi, di cui il più evidente è il cambiamento climatico, che può portare a veri e propri scompensi ambientali anche nel breve periodo fino a vere e proprie catastrofi (se l’aumento di temperatura supererà i 3°C). Questo problema non è risolvibile istantaneamente ma è fondamentale cominciare a fare qualcosa: un sistema di incentivi che promuova il rinnovabile e adottare nuovi sistemi di sfruttamento dell’energia. In tale ambito sono stati fatti grandi passi, ma bisogna continuare in questo senso. Risulta quindi fondamentale l’utilizzo di energie rinnovabili, che hanno il grande vantaggio di non essere inquinanti ma allo stesso tempo, non essendo programmabili, per poterle sfruttare al meglio e in modo istantaneo necessitano di sistemi di accumulo che permettano all’utente di soddisfare immediatamente la richiesta. Studiamo quindi il comportamento di un sistema di approvvigionamento alimentato da fonte rinnovabile non programmabile per la produzione di idrogeno, che permette un semplice stoccaggio in bombole a una pressione relativamente bassa (10 bar), consentendone l’utilizzo sia come idrogeno purissimo che in un metanatore. In particolare verificheremo il comportamento del sistema di accumulo a gel di piombo; per ottenerne il miglior rendimento, ricercandone la migliore efficienza e le curve di funzionamento. Per ottenere la migliore efficienza del sistema occorre che i componenti vengano progettati, studiati ed utilizzati nelle più performanti condizioni di lavoro.

Abstract:
I camici protettivi in piombo, grazie alle elevate proprietà di assorbimento e di attenuazione delle radiazioni da parte del materiale, sono sempre stati i principali dispositivi di protezione personale utilizzati nel campo della diagnostica radiologica e nelle procedure interventistiche. Nella campo della radioprotezione in Medicina Nucleare invece, è molto vivo il dibattito tra coloro i quali ritengono che l’utilizzo dei DPI, come i camici in gomma al Piombo, non sia particolarmente efficace e quelli che, al contrario, ne suggeriscono l’uso. Obiettivo di questo lavoro di tesi, è stata la valutazione dell’efficienza dei camici in gomma al piombo nel campo della Medicina Nucleare secondo un approccio di tipo Monte Carlo. E’ stato cosi realizzato in FLUKA e successivamente validato, un modello di tubo radiogeno attraverso il quale studiare le proprietà di attenuazione del materiale e la sua equivalenza al piombo per i due spessori maggiormente usati nella caratterizzazione dei camici protettivi, ovvero 0.25 mm Pb e 0.50 mm Pb. E’ stato cosi realizzato un camice in gomma al piombo modellato sulla geometria voxel del fantoccio di riferimento ICRP, importato in FLUKA e utilizzato in diverse situazioni di irraggiamento mediante la definizione di tre sorgenti puntiformi di 18 F, 131 I e 99m TC. I risultati delle simulazioni sono state infine oggetto di un analisi dosimetrica sul fantoccio per valutare l’efficienza della protezione in gomma al Pb.

Abstract:
The anned stmggle carried out by leftist groups in Italy during the 1970s and 1980s has been the subject ofmuch debate in tenns of both public opinion and the mass media from its very start to the present day. It represents a fundamental and dramatic phenomenon in recent Italian history, a phenomenon that involved the death of 128 victims (and of 68 militants), hundreds of serious woundings and robberies; it was a long-lasting and widespread movement, supported by - at least - 30,000-40,000 people and involving a number ofactive groups. This research concentrates on the personal image of some of the militants in the largest of such groups, the Brigate Rosse (Red Brigades). Two kinds of images are analysed: the ones created by the mass media and the ones the militants produced through their own autobiographical writings (more than twenty such texts have been published). This thesis analyses what was said or written about the militants in question during the Seventies and Eighties, not only in magazine and newspaper articles and historical essays, but also in movies, songs and biographies. The analysis aims to reach a better understanding ofhow Italian society views these individuals today, and how those views have been produced. Most Italians see the 'ex brigatisti' just as they did thirty years ago, and the juxtaposition of these public frozen identities with the personal ones held by the militants, as revealed in their autobiographies, is one of the two main goals ofthis study. A second, related goal of this research, is to carry out a detailed textual analysis of four selected texts (the autobiographies of Curcio, Peci, Franceschini and Balzerani), tracing the writers' stylistic and stmcturai choices in order to understand how they attempt to create their personal identity and present it to the reader. The Primary Sources of my research consist in the texts published by exmilitants, which include primarily autobiographies, but also essays, poetry, novels, and other material. Secondary Sources consist mostly of texts about the anned stmggle in Italy written by Italian and foreign experts. These include newspaper articles, biographies, interviews, and critical works on the creation ofpersonal and collective identity.

Ostrich is an ratit bird that originated from Africa. In Brazil is found manly in commercial farms. The number of farms that raise ostriches is growing in Brazil due to the great reproductive potential of these birds and the great economic value of its products. Because of this increase in raising of ostriches, parasites have appeared of which little is known or studied, thus raising the need for study and description of these parasites to the scientific community and breeders. With the objective of studying the presence of parasitess in ostriches from commercial farms in the Rio Grande do Sul State, heads, respiratory and digestive systems were examined individually from 34 ostriches as well as a collection of their feathers. The material was collected during the slaughter in the Castilhense Abattoir, located in the city of Julio de Castilhos, RS. The contents and mucous membrane of the small intestine, cecum and large intestine were examined; as well as the mucous of the esophagus, proventriculus and gizzer; lung, trachea and pancreas were examined; as well as the exterior, oral, nasal and ocular cavities of the head. Nematodes were found in the digestive and respiratory systems and lice and mites in feathers. The nematodes were clarified with lactophenol and identified as Libyostrongylus douglassii, L. dentatus and Codiostomum struthionis. The lice were clarified using metil salicilate, the mites with lactophenol and identified respectively as Struthiolipeurus rheae and Struthiopterolichus sculpturatus. This is the first description of C. struthionis in ostriches in the Rio Grande do Sul state and L. dentatus in Brazil, as well as the simultaneous parasitism of L. douglassii and L. dentatus in the same host in these country. This is also the first report of S. rheae and S. sculpturatus in ostriches from the Rio Grande do Sul state.
Avestruz é uma ave ratita originária da África. No Brasil é encontrada, principalmente, em criatórios comerciais, os quais vem se expandindo no país devido ao alto potencial reprodutivo destas aves, bem como pelo valor econômico de seus produtos. Devido a esse aumento na criação comercial tem ocorrido a detecção de parasitos pouco conhecidos ou estudados, havendo a necessidade de descrição desses à comunidade científica e aos criadores, pois podem causar um impacto negativo no plantel. Com o objetivo de pesquisar parasitos em avestruz de criatórios comerciais do RS, examinaram-se individualmente as cabeças e os sistemas digestório e respiratório de 34 aves, bem como, coletivamente, suas plumas. O material foi coletado durante o abate no frigorífico Castilhense localizado no município de Júlio de Castilhos, RS. Os conteúdos e as mucosas do intestino delgado, ceco e intestino grosso; mucosas do pró-ventrículo, moela e esôfago; pulmão, traquéia e pâncreas foram examinados, além da superfície externa da cabeça bem como as cavidades oral, nasal e ocular. Encontraram-se nematóides no sistema digestório e piolhos e ácaros nas plumas. Os nematóides encontrados foram clarificados em lactofenol e identificados como Libyostrongylus douglassii, L. dentatus e Codiostomum struthionis. Os piolhos foram clarificados em salicilato de metila, os ácaros em lactofenol e identificados, respectivamente, como Struthiolipeurus rheae e Struthiopterolichus sculpturatus. Faz-se o primeiro registro de C. struthionis em avestruz no RS e L. dentatus no Brasil, assim como o parasitismo simultâneo de L. douglassii e L. dentatus. Registra-se também a ocorrência de S. rheae e S. sculpturatus pela primeira vez em avestruz no Rio Grande do Sul.

Abstract:
This thesis considers some of those who were killed in politically-motivated attacks, often referred to as ‘terrorism’, which took place during Italy’s anni di piombo. Six works written by victims’ children will be used as a lens through which to examine the collective memory and the victims’ place therein. In recent years, there has been a shift in the way that this period of Italian history - the anni di piombo – has been remembered. Where previously the perpetrators of the violence of those years dominated public discourse, in the last decade the principal narrative has become more victim-centred. The biographical works written by victims’ children have inevitably contributed to this change in the memory narrative. The techniques employed in their writing in order to change the existing public image of their fathers will be analysed in this thesis, along with certain themes that recur throughout the six works and broader victim-centred discussion of this period. Analysis begins with a thorough outline of the political and historical context of the anni di piombo, including case studies of two of the most famous victims of this period and a consideration of the written works of some of the former terrorists. Following this preliminary contextualisation, each of the six books and their authors will be studied in detail to provide a foundation for the analysis contained in the final three chapters. The themes examined in the second half of the thesis are second-generation writing, forgiveness and commemoration. Using these themes as a framework, a rigorous investigation of the place that the victims hold in collective memory; the role their children’s writing has played in shaping and maintaining their public image and the longer-term impact that these changes can be seen to have had within a broader societal and political perspective is undertaken. On the basis of this study, it is evident that the victims’ place in the collective memory of the anni di piombo has changed dramatically since that period of violence concluded. The victims’ children have been very significant in enacting this change and their writing has placed them in a position from which they can continue to exert influence and promote a victim-centred approach to history.

Abstract:
Según Duclos (2017, p. 199), en los años ochenta y noventa del siglo pasado, los mercados de pulgas se desarrollan en diversas ciudades de Europa, son formas de economía popular, callejeras, mercantiles e informales, en las que prevalecen relaciones cara a cara y la alteridad compartida, entre ellos, los mercados de pulgas parisinos. Los mercados de pulgas informales de Paris, son espacios de resocialización para quienes han perdido lazos laborales, son también puerta de entrada a la ciudad para inmigrantes recién llegados, estos mercados son lugares de socialidad. Por su parte Salazar (2010, p. 93) dice que los tianguis urbanos en la Ciudad de México tienen alta valoración, aun cuando las autoridades en diferentes niveles han intentado regular o restringir el comercio en tianguis, éstos continúan siendo masivamente visitados, y tanto tianguistas como consumidores se desenvuelven en un ambiente de seguridad y confianza, sustentado por las mismas prácticas de convivencia de los sujetos involucrados en las transacciones comerciales.
La ciudad es una construcción social en constante transformación. Entre otras, están las prácticas sociales derivadas de encuentros de los individuos realizadas en un espacio dado; donde confluyen diferentes maneras de percibir y construir lo cual genera lo mismo afinidades que conflictos. Por ejemplo, las prácticas del comercio callejero con el comercio formal en un área o lugar, donde convergen relaciones de identidad entre vendedores y compradores y, la no aplicación de ordenanzas formales por otras sociales. El comercio en la vía pública (fijo, semifijo y ambulante), históricamente ha construido espacio público tanto como espacio social como lugar de generación de trabajo, es una forma de vida. En las ciudades, sin embargo, se observan zonas con demanda social por lo público, donde el espacio comercial suple esa carencia, por ello requiere replantearse el papel de lo público, de la apropiación simbólica y ocupación de los espacios urbanos.

Abstract:
Memoria para optar al Título Profesional de Médico Veterinario
El piojo de mar (Caligus rogercresseyi) es un copépodo ectoparásito que afecta a la industria del cultivo de salmónidos en el sur de Chile, disminuyendo el estado de salud de los peces y produciendo pérdidas económicas directas e indirectas. Miembros de la industria han notificado niveles de infestación crecientes desde 2004, alcanzándose los máximos niveles en 2007. En respuesta a esta situación, el Servicio Nacional de Pesca (SERNAPESCA) desarrolló un sistema de vigilancia, cuyo primer paso consistió en realizar una revisión general a lo largo de los centros de cultivo de salmónidos. Esta incluyó la medición de los niveles de infestación en los peces y el registro de varios factores derivados de condiciones de manejo y ambientales. El objetivo del presente estudio fue identificar los factores de riesgo para los niveles observados de infestación, derivados de las variables ambientales y de manejo registradas en dicha etapa. La información fue analizada utilizando el método de los modelos lineales de efectos mixtos (MLM), el cual permite la estimación del efecto de los factores de riesgo y la descomposición de la variación no explicada, asignándola a los diferentes niveles de anidamiento del sistema productivo, en este caso subzona, centro de cultivo y jaula. Las variables zona geográfica, especie de los peces, tratamientos contra el piojo de mar aplicados un mes antes del muestreo, densidad de cultivo, peso de los peces y salinidad del agua, estuvieron significativamente asociadas con los niveles de infestación con piojo de mar. Tratamientos dos y tres meses antes del muestreo, uso del fotoperiodo en las balsas jaula y la temperatura del agua no resultaron significativas. La variación no explicada fue significativa en todos los niveles de anidamiento, siendo la variación a nivel de centro de cultivo la mayor. Entre las causas de tal variación pueden participar diversos factores, incluyendo diferencias en las corrientes marinas locales, en la distribución de los hospederos silvestres, en el estatus sanitario de los centros, o de las jaulas dentro de estos, y diferencias en prácticas o eventos potencialmente estresantes, como tratamientos con medicamentos y vacunas inyectables, o ataques de lobos marinos y pájaros, entre otros. Finalmente, se proponen futuras áreas de investigación que permitan mejorar la comprensión y el control de esta enfermedad.

Full text
Abstract:
GABAA receptors are the major inhibitory ligand-gated ion channels in the mammalian CNS. They mediate their physiological effects via two temporally and spatially distinct forms of signalling, denoted as phasic and tonic inhibition. These two forms of inhibition are mediated by distinct GABAA receptor subtypes, with phasic inhibition relying on the activation of synaptically-located γ2 subunit-containing receptors, and tonic inhibition requiring the activation of extrasynaptic receptors, predominantly thought to contain δ-subunits. The importance of tonic inhibition in regulating cell and network excitability has become increasingly apparent. Moreover, elevated tonic currents accompany neurological disorders such as stroke and absence epilepsy, suggesting that selectively reducing tonic inhibition might be therapeutically useful. Due to a lack of δ-selective antagonists, the theoretically predominant antagonist profile of the weak partial agonist, 4-PIOL, was studied as a potential mechanism for selectively reducing tonic inhibition. The functional effects of 4-PIOL were investigated firstly on whole-cell GABA-activated currents of several recombinant γ2- and δ-containing receptors expressed in HEK293 cells. As expected for a partial agonist, 4-PIOL exhibited both agonist- (at γ2-subunit GABAA receptors) and antagonist-type (at δ-subunit receptors) behaviours, depending on the GABA concentration. 4-PIOL was then assessed on tonic and phasic currents of cerebellar granule cells (CGCs), hippocampal pyramidal neurons and thalamic relay-neurons. In CGCs, 4-PIOL inhibited tonic currents, without affecting spontaneous inhibitory postsynaptic currents (sIPSCs); whereas in hippocampal and thalamic relay neurons, 4-PIOL enhanced, or reduced, tonic currents depending on the extrasynaptic GABA concentration, consistent with an action at extrasynaptic γ2-containing receptors. Moreover, 4-PIOL antagonised sIPSCs in these two brain regions, in accord with targeting presynaptic and postsynaptic GABAA receptors. In conclusion, the therapeutic potential of GABAA receptor partial agonists, such as 4-PIOL will be critically dependent on not only the ambient GABA concentration, but also on the relative expression of different GABAA receptor subtypes.

Abstract:
In recent decades, insect sex pheromones are playing an increasingly important role in the detection, monitoring and control of pests, becoming part of Integrated Management strategies and helping to reduce the amount and use of conventional pesticides. The implementation of control techniques based on pheromones makes it necessary to obtain these substances through organic synthesis. Oleander Scale, Aspidiotus nerii Bouché, 1833, is a cosmopolitan and polyphagous pest that attacks more than 100 plant families. In Spain, it is a coccoid pest of medium-importance for citrus crops, after California red scale (Aonidiella aurantii Maskell), Chaff scale (Parlatoria pergandii Comstock) and Purple scale (Lepidosaphes beckii Newman). Conventional chemical control against Oleander scale is sometimes ineffective due to the biology of the pest and the increasing restrictions on the number of available pesticides; thus, a possible treatment of this pest based on its sex pheromone would be highly valuable. The sex pheromone of A. nerii was identified by Einhorn et al. in 1998 as (1R,2S)-cis-2-isopropenyl-1-(4¿-methyl-4¿-penten-1¿-yl)cyclobutaneethanol acetate. Its synthesis has been approached by various authors but the synthetic routes described until now have a high number of synthetic stages and a low overall yield, which makes it not suitable for a multigram scale synthesis. It can be highlighted the synthesis of Einhorn et al., in 1998, involving 17 steps and an overall yield of 0.40% or the total synthesis developed in the same year by Guerrero et al., with 15 steps and an overall yield of 5.6%. For these reasons, this thesis addresses the development of a synthetic route that improves the existing ones to obtain the sex pheromone of A. nerii at a multigram scale. The synthetic route developed in this work is based on low cost commercial substrates such as 3-hydroxypropanenitrile, which can be transformed into the pheromone of interest using only 10 steps and with an overall yield of 10.3%. The proposed route employs simple purification procedures and several reactions including a Blaise reaction and a [2 + 2] photocycloaddition as key reactions. In addition, some of the synthetic intermediates obtained in this proposed route have high interest to improve the synthesis of the aggregation pheromones of Diaprepes abbreviatus Linnaeus and Trypodendron lineatum Olivier, which represent important pests in different countries. The possibility of obtaining a sufficient amount of A. nerii sex pheromone has allowed the realization of field trials, which are expected to contribute significantly to the development of alternative techniques for the control of this pest in crops of interest in Spain and other countries.
El uso de las feromonas sexuales de insectos para la detección, seguimiento y control de plagas ha ido creciendo de manera constante en los últimos años, convirtiendo a estas sustancias en una de las herramientas más importantes en la lucha contra poblaciones de insectos dentro del Manejo Integrado de Plagas, ayudando así a reducir la cantidad y el uso de plaguicidas convencionales. La aplicación de estas técnicas hace necesaria la obtención de estas sustancias mediante síntesis orgánica. El piojo blanco del limón Aspidiotus nerii Bouché, 1833, también conocido como piojo de la adelfa (Oleander scale), es una plaga cosmopolita y polífaga que ataca a más de 100 familias de plantas. En España constituye una plaga de cóccidos de importancia media en el cultivo de cítricos después del piojo rojo de California (Aonidiella aurantii Maskell), el piojo gris (Parlatoria pergandei Comstock) y serpeta gruesa (Lepidosaphes beckii Newman). Su tratamiento mediante plaguicidas tradicionales es en ocasiones poco efectivo debido a la biología de la plaga y a las crecientes restricciones en cuanto al número de plaguicidas disponibles, por lo que un posible tratamiento de esta plaga basado en su feromona sexual tendría un alto interés. Hasta el momento la síntesis de la feromona sexual de A. nerii, identificada por Einhorn et al. en 1998 como acetato de 2-[(1R,2S)-cis-2-isopropenil-1-(4¿-metil-4¿-pentenil)-ciclobutano]etilo, ha sido llevada a cabo por diversos autores pero las rutas sintéticas descritas para obtener esta feromona, presentan un elevado número de etapas sintéticas y un rendimiento global bajo, no resultando adecuadas para llevarlas a escala multigramo. Se puede destacar la síntesis de Einhorn et al., en 1998, que involucra 17 etapas y un rendimiento global de 0.40% o la síntesis total desarrollada por ese mismo año por Guerrero et al. con 15 etapas y un rendimiento global de 5.6%. Por estas razones, en la presente tesis se aborda el desarrollo de una ruta sintética que mejore las existentes para obtener la feromona sexual del piojo blanco del limón (A. nerii) a escala multigramo. La ruta sintética desarrollada en este trabajo parte de sustratos comerciales de bajo coste como el 3-hidroxipropanonitrilo, el cual puede ser transformado en la feromona de interés empleando únicamente 10 etapas y con un rendimiento global de 10.3%, con procedimientos de purificación sencillos y mediante diversas reacciones que incluyen como reacciones clave una reacción de tipo Blaise y una fotocicloadición de tipo [2+2]. Asimismo, algunos de los intermedios sintéticos obtenidos en esta ruta propuesta son de alto interés para mejorar las síntesis de las feromonas de agregación de Diaprepes abbreviatus Linnaeus y de Trypodendron lineatum Olivier, las cuales representan plagas importantes en diferentes países. La posibilidad de obtener cantidad suficiente de la feromona sexual de A. nerii, ha permitido la realización de ensayos en campo, y se espera generar un aporte significativo en el desarrollo de técnicas alternativas para el control de esta plaga en cultivos de interés en España y en otros países.
L'ús de les feromones sexuals d'insectes per a la detecció, seguiment i control de plagues ha anat creixent de manera constant en els darrers anys, convertint aquestes substàncies en una de les eines més importants en la lluita contra poblacions d'insectes dins el Control Integrat de Plagues, ajudant així a reduir la quantitat i l'ús de plaguicides convencionals. L'aplicació d'aquestes tècniques fa necessària l'obtenció d'aquestes substàncies mitjançant síntesi orgànica. El poll blanc de la llimona Aspidiotus nerii Bouché, 1833, també conegut com poll del baladre (Oleander scale), és una plaga cosmopolita i polífaga que ataca més de 100 famílies de plantes. A Espanya constitueix una plaga de còccids d'importància mitjana en el cultiu de cítrics després del poll roig de Califòrnia (Aonidiella aurantii Maskell), el poll gris (Parlatoria pergandei Comstock) i serpeta gruixuda (Lepidosaphes beckii Newman). El seu tractament mitjançant plaguicides tradicionals en ocasions és poc efectiu a causa de la biologia de la plaga i a les creixents restriccions pel que fa al nombre de plaguicides disponibles, de manera que un possible tractament d'aquesta plaga basat en la seua feromona sexual tindria un alt interès. Fins al moment la síntesi de la feromona sexual d'A. nerii, identificada per Einhorn et al. el 1998 com a acetat de 2-[(1R,2S)-cis-2-isopropenil-1-(4'-metil-4'-pentenil)-ciclobutàn]etil, ha estat portada a terme per diversos autors però les rutes sintètiques descrites per obtenir aquesta feromona, presenten un elevat nombre d'etapes sintètiques i un rendiment global baix, no resultant adequades per al pas a escala multigram. Es pot destacar la síntesi de Einhorn et al., El 1998, que involucra 17 etapes i un rendiment global de 0,40% o la síntesi total desenvolupada per aquest mateix any per Guerrero et al. amb 15 etapes i un rendiment global de 5.6%. Per aquestes raons, en la present tesi s'aborda el desenvolupament d'una ruta sintètica que millore les existents per obtenir la feromona sexual del poll blanc de la llimona (A. nerii) a escala multigram. La ruta sintètica desenvolupada en aquest treball parteix de substrats comercials de baix cost com el 3-hidroxipropanonitril, el qual pot ser transformat en la feromona d'interès emprant únicament 10 etapes i amb un rendiment global de 10.3%, amb procediments de purificació senzills i mitjançant diverses reaccions que inclouen com a reaccions clau una reacció de tipus Blaise i una fotocicloaddició de tipus [2 + 2]. Així mateix, alguns dels intermedis sintètics obtinguts en aquesta ruta proposada són d'alt interès per millorar les síntesis de les feromones d'agregació de Diaprepes abbreviatus Linnaeus i de Trypodendron lineatum Olivier, les quals representen plagues importants en diferents països. La possibilitat d'obtenir quantitat suficient de la feromona sexual d'A. nerii, ha permès la realització d'assajos en camp, i s'espera generar una aportació significativa en el desenvolupament de tècniques alternatives per al control d'aquesta plaga d'importància en cultius d'interès en Espanya i en altres països.

Abstract:
Les enquêtes historiques menées ces dernières années sur la préciosité et les précieuses ont permis de mettre en valeur le rôle tenu par ces dernières dans la société du XVIIe siècle et leur place dans la constitution du champ littéraire. Reconsidérer alors la vie et l'œuvre de Mme de Lafayette à la lumière de la préciosité a permis de manifester la vérité du jugement des frères de Villers qui, en 1658, affirmaient que la comtesse était « une des prétieuses du plus haut rang et de la plus grande volée ». Sa vie le confirme en effet, qui la place au cœur d'un réseau précieux et révèle une personnalité, un tempérament, une psychologie propres aux précieuses. L'étude des œuvres susceptibles de constituer la culture précieuse de Mme de Lafayette, l'Heptaméron de Marguerite de Navarre, le théâtre de Corneille, l'Astrée d'Honoré d'Urfé et la production romanesque de Mlle de Scudéry ont permis une lecture nouvelle des œuvres de Mme de Lafayette, invitant à y reconnaitre des thèmes, une éthique, voire une esthétique, ainsi qu'une vision du monde propres à la préciosité. Les investigations ainsi menées ont permis de faire un portrait de la comtesse en précieuse et de mettre en valeur, à travers une œuvre originale, ce qui fut, parmi d'autres, une stratégie possible de la préciosité.

Full text
Abstract:
Cette thèse explore le discours éditorial des féministes à travers trois revues phares du mouvement québécois, Québécoises deboutte!, Les têtes de pioche et La Vie en rose, afin de saisir les stratégies de positionnement des féministes. Ces dernières adaptent leur rhétorique de manière à définir un mouvement qui se construit à travers une prise de parole collective, laquelle se transforme à mesure que le champ sociopolitique québécois des années 1970 se configure lui aussi. Nous avons ainsi constaté trois tendances qui se dégagent des textes. Dans un premier temps, Québécoises deboutte! oriente sa rhétorique de manière à ratisser largement le terrain militant et à capter l’attention d’alliés potentiels entre les pôles marxiste et contre-culturel. La revue Les têtes de pioche a pour sa part opéré un retranchement vers la zone spécifiquement féministe afin de se distinguer des autres luttes présentes dans le champ et de travailler à expliquer et combattre, par la prise de parole, l’oppression spécifique des femmes. Finalement, La Vie en rose se présente comme porte-étendard d’un féminisme qui se veut pluriel, présentant à la fois les acquis du féminisme radical et les aspirations des féministes d’une génération nouvelle. L’émergence des revues féministes au Québec reste indissociable d’une perspective sociale en regard de la place qu’occupent les féministes dans les champs culturel, intellectuel et littéraire. Notre recherche se développe en deux parties complémentaires visant à mettre en lumière l’organisation du discours féministe à travers différentes revues et à analyser l’évolution de cette littérature d’idées de manière interne (discours) et externe (effets de champ). À travers vingt années de militantisme textuel, la démarche éditoriale globale des féministes forme aussi un tout cohérent. Les initiatives journalistiques du féminisme présentent en effet une logique interne qui se circonscrit au fil des ans pour, ultimement, constituer un système discursif – et rhétorique – singulier, où l’argumentation par l’éthos occupe une fonction prépondérante. La thèse se penche sur les caractéristiques littéraires des textes, nous étudions l’émergence de la presse féministe comme un phénomène plus large dépassant le cadre de la page, car elle concerne aussi l’histoire et la structure du champ littéraire, de même que les problématiques – tant formelles que sociales – qui lui sont reliées.
This thesis explores the feminist’s editorial speech among three well-known feminist magazines of Quebec which are Québécoises deboutte!, Les têtes de pioche and La Vie en rose in order to understand the strategies and the posture of the feminists. Feminists adapt their rhetorics in order to define a movement that builds itself through a collective speech which is evolving as the sociopolitical context of Quebec in the seventies is. We have been able to observe three major tendencies among the texts. First of all, Québécoises deboutte! builds a speech to wrap up the different forms of activism together and to obtain the attention of potential allies who may be between the marxist and the counter-cultural poles. Secondly, Les têtes de pioche orients its speech toward a specifically feminist zone in order to distinguish itself from the other social fights. That magazine also works to explain and fight by using words the specific oppression of women. And finally, La Vie en rose presents itself as the standard bearer of the plurality of the feminist voices, showing at the same time the wins of radical feminism and the hopes of a new generation of feminists. In Quebec, the rise of the feminist magazines is an integral part of a social perspective which shows us the implication of the feminists in the fields of culture, philosophy and literature. Our research develops in two complementary parts which try to show the mechanism of the feminist speech by analyzing the content of different magazines and the evolution of this literature of ideas in an internal way (speech) and an external (field effects) one. Through twenty years of textual activism, we see that the editorial approach of the feminists forms a consistent whole. The journalistic efforts of feminism reveal an internal cohesion that consolidates itself year after year to, ultimately, become a system of ideas – and rhetorical – which is unique and into which the argumentation is mainly based on the ethos. Our thesis particularly study the literary aspects of the texts, the rise of the feminist press as a phenomenon that goes beyond the paper – because it concerns the history and the constitution of the literary field – the social and the formal problematics that are related to it.

Abstract:
Dans ce travail à visée interprétative, une analyse systématique du lexique de Mme de Lafayette (la fréquence des mots ou leur rareté, les hapax et les absents) a permis ces conclusions : - c’est en réalité par la Comtesse de Tende, sa nouvelle posthume, qu’elle a inauguré sa carrière narrative. - La suspicion tenace ne résiste pas à notre étude : la comtesse de Lafayette est le seul auteur d’une oeuvre qu’on lui a souvent contestée ; les concours amis furent réels, mais jamais décisifs. - On s’est bien sûr intéressé surtout à la Princesse de Clèves : - on a approfondi deux énigmes : l’effacement de Dieu dans un monde qui ne cesse de l’invoquer, et l’explosion sensuelle de la nuit de Coulommiers dans un roman si discret sur les desseins du corps et même son dessin. - On a fait litière d’explications souvent avancées : la vertu, le poids de l’éducation, la conscience d’une culpabilité. - Telle est, dans l’histoire littéraire du renoncement, la singularité de la princesse : l’heure de la liberté (son mari meurt…) ne la livre pas éblouie à la promesse du bonheur partagé avec le duc de Nemours, mais – au terme d’une série de crispations – lui dicte un refus de vivre fondé sur la certitude que la réel détruit la passion. - La solitude choisie par Mme de Clèves est crépusculaire. Vient seule l’atténuer la conjonction de la mémoire et de l’imaginaire ; il faut croire à cette présence de l’Absent. Quand Segrais, l’une des plumes prêtées à la romancière par la rumeur, inspire cette question rhétorique à l’une de ses héroïnes : « Mais qui peut vivre sans aimer ? », le roman propose sa leçon d’abîme : la princesse peut aimer sans vivre. - Le stoïcisme de Du Vair, l’analyse cartésienne des passions, Pascal et l’univers de Port-Royal : on a étudié la curiosité de Mme de Lafayette pour ces mondes intellectuels et les limites de sa sympathie
In this interpretive work, a systematic analysis of Mme de Lafayette's lexicon (the frequency of the words or their rarity, the hapaxa and the absentees) allowed these conclusions: - It is really by La Comtesse de Tende, her posthumous short story, that she inaugurated her narrative career. - This study pots an end to the oft-debated authorship controversy: The Countess de La Fayette is the only author of her work. There is no denying that she was assisted by friends, but never decisively. - We were naturally interested especially in La Princesse de Clèves : - We have fathomed two enigmas: the disappearance of God in a world which does not stop calling upon him, and the sensual explosion of the night in Coulommiers in a novel which tells so little about the intentions of the body and even its representation. - We have discarded oft-advanced explanations: virtue, the weight of education, the consciousness of a fault. - Here is, in the literary history of the renonciation, the peculiarity of the Princes: the time for freedom (her husband dies. . . ) does not deliver her into dazzling promises of happiness shared with the Duc de Nemours, but - at the end of a series of tensings - dictates her a refusal to live based on the certainty that the reality destroys the passion. - The solitude chosen by Mme de Clèves is in the twilight. Only the conjonction of the memory and the imagination cornes to ease it; it is necessary to believe in the presence of the Absentee. While Segrais, one of the presumed pens credited to the novelist by the rumour, inspired this rhetoric question to one of his heroines: "But who can live without loving?", the novel proposes to explore the depths of despair: the princes can love without living. - We have shown Mme de Lafayette's interest in Du Vair's Stoicism, the Cartesian analysis of the passio ns, Pascal and the philosophy of Port Royal as well as the limits of her sympathy with these intellectual worlds

Los piojos de mar (Caligus rogercresseyi) son los ectoparásitos que causan las mayores pérdidas productivas en la industria de la acuicultura, especialmente en Chile. El salmón del Atlántico (Salmo salar) y la trucha arcoíris (Oncorhynchus mykiss) son las especies de salmónidos más susceptibles a su infestación, una situación que ha promovido la búsqueda de estrategias para resolver el problema. Este estudio tiene como objetivo determinar genes candidatos en el salmón del Atlántico y la trucha arcoíris que pueden participar en el mecanismo de resistencia contra el piojo de mar, y determinar la ortología entre los genes obtenidos en ambas especies. Para esto, 2.626 individuos de salmón del Atlántico y 2.643 de trucha arcoíris de poblaciones comerciales fueron desafiados con piojos de mar y se les realizó un genotipado con un panel de SNP 50k. Se obtuvieron heredabilidades moderadas a bajas con valores de 0,19 para S. salar y 0,08 para O. mykiss para el logaritmo de la densidad del caligus (como medida de resistencia del huésped). Mediante un estudio de asociación genómica identificamos una serie de genes presentes las regiones genómicas asociadas al carácter en ambas especies, tales como Serine/ threonine kinase y Tripartite motif-containing protein 16-like. El análisis de ortología nos permitió identificar dust8 y dust10 como genes que participan en la respuesta inmune activando los leucocitos, favoreciendo la migración, como también al receptor de ácido lisofosfatidico junto a un receptor acoplado a proteína G los cuales pertenecen a regiones sinténicas asociadas al carácter en ambas especies. Este es un primer enfoque para comprender los genes involucrados en la resistencia contra el piojo de mar utilizando genómica comparativa en salmónidos. Sin embargo, se necesitan investigaciones adicionales en ambas especies para validar los genes identificados como candidatos
Sea lice (Caligus rogercresseyi) are the ectoparasites that cause the greatest productive losses in the aquaculture industry, especially in Chile. Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) are the salmonid species most susceptible to their infestation, a situation that has promoted the search for strategies to solve the problem. This study aims to determine candidate genes in Atlantic salmon and rainbow trout that can participate in the mechanism of resistance against sea lice, and determine the orthology between the genes obtained in both species. For this, 2,626 individuals of Atlantic salmon and 2,643 of rainbow trout from commercial populations were challenged with sea lice and genotyped with a SNP 50k panel. Moderate to low heritabilities were obtained with values of 0.19 for S. salar and 0.08 for O. mykiss for the logarithm of sea lice density (as a measure of host resistance). By means of a study of genomic association we identified a series of genes present the genomic regions associated with the character in both species, such as Serine / threonine kinase and Tripartite motif-containing protein 16-like. The orthology analysis allowed us to identify dust8 and dust10 as genes that participate in the immune response activating the leukocytes, favoring migration, as well as the lysophosphatidic acid receptor together with a G protein-coupled receptor which belong to syntenic regions associated with the character in both species. This is a first approach to understand the genes involved in resistance against sea lice using comparative genomics in salmonids. However, additional research is needed in both species to validate the genes identified as candidates

Abstract:
Cette thèse propose une réflexion sur la peinture sur pierre en Italie dans les années 1530-1630. Elle se compose de trois volumes dont le premier est constitué de trois parties qui s'organisent autour de thématiques, de centres – Rome, la Vénétie, Florence, la Lombardie et la Ligurie - et d'artistes clefs. Les interrogations sur l'origine et la diffusion de la technique par le biais de l'analyse des traités et des pierres constituent notre première partie. Puis, deux types bien distincts de production orientent nos analyses : la peinture sur ardoise et la peinture sur pierres imagées. Sebastiano del Piombo, artiste vénitien, est à l'origine du développement de cette technique à Rome. Ces premières expérimentations sur ardoise, liées au problème de conservation, servent rapidement de modèles aux artistes présents à Rome. Des peintures d'autel aux peintures de chevalet, la technique connaît un important engouement sur l'ensemble du territoire italien à partir des années 1530 jusqu'au milieu du XVIIe siècle. Parallèlement, la passion accordée à la culture de la curiosité et de la préciosité explique l'emploi de pierres semi-précieuses à partir des années 1580. Ces deux tendances organisent l'ensemble de notre réflexion. Le second volume complète nos propos en fournissant des documents d'archives, un catalogue raisonné qui a contribué à déterminer les axes à étudier. Enfin, le troisième volume sert de supports visuels à nos écrits. This thesis gives a reflexion on painting on stone in Italy during the years 1530-1630. It consists of three volumes. The first one has three parts organized around thematic, centers – Rome, Florence, Liguria, Venetia, and Lombardy – and famous artists. The first part approaches the origins and the development of painting on stone by studying the treatises and the characteristic of stones. The second part recalls the practice of painting on slates and the third one the painting on precious stones like lapis-lazuli. Sebastiano del Piombo starts to paint on stone and gives an example for all Italy which explains different types of productions – from altars to small pictures – and development from 1530 until the middle of the XVIIe century. But his experience is really different from painting on precious stone, practice which starts around 1580. This supports deals with the taste for curiosity and preciosity and has nothing to do with experimentations on slate. The second volume contains supplements with records documents and a descriptive catalogue of all the works we found during the research. This catalogue helps us in choosing the different themes we had to speak about. The third volume gives reproductions.

Rien que par l'etude du vocabulaire utilise par l'auteur, on se rend compte de la place preponderante qu'occupe la feinte dans l'oeuvre de madame de lafayette. Le milieu qu'elle met en scene etant la cour, on utilise pour les divertissements (bals masques, ballets, tournois) des masques et des deguisements ; tandis que pour leurs jeux politiques comme pour leurs amours, les heros sont souvent obliges de cacher leurs sentiments pour les mener a bien. On rencontre pourtant dans cette oeuvre, des personnages qui aiment la verite, ainsi que des instants de verite. Mais, celle-ci n'est jamais totale. La societe de la cour favorise le mensonge. Ici, il n'y a que l'apparence qui compte. La curiosite des autres, leur indiscretion, et les regles de la bienseance empechent que l'on se montre tel qu'on est. A cela, viennent s'ajouter les limites de la morale elle-meme ainsi que l'esthetique adoptee par l'auteur qui se sert des jeux de la feinte et de la verite pour faire evoluer l'action romanesque
By the mere study of the vocabulary used by the author, one can realize the prominent part played by make-believe in madame de lafayette's work. The social class she depicts being the court, masks and fancy-dress are used for entertainment such as fancy-dress balls, ballets and tournaments-whilst for their political games as well as in love-making, the heroes are often bound to hide their feelings to bring them to a successful issue. One sometimes meets in this work, however, characters who love truth, as well as moments of truth : but this very truth is never complete. The world of courtiers favours untruth : there, only appearance is taken into account. The others' curiosity, their indiscretion and rules of propriety prevent one from showing one's real self. To this must be added the limits of morals as well as the aesthetics adopted by the author who uses the processes of make-believe and of truth to make romantic action evolve

Abstract:
Esta tesis describe la situación del control biológico del piojo rojo de California, Aonidiella aurantii (Maskell) (Hemiptera: Diaspididae), por parasitoides en la Comunidad ValencianaEl piojo rojo de California es una de las plagas más importantes de cítricos en España. Esta plaga, a pesar de todos los tratamientos químicos que se realizan para su control, se encuentra por encima del umbral económico de daños.En este trabajo se constata, tras un muestreo realizado a lo largo de un año, que Aphytis chrysomphali (Mercet) (Hymenoptera; Aphelinidae) es el parasitoide mayoritario de esta cochinilla en la Comunidad Valenciana, a pesar de todas las sueltas realizadas desde los años 70 de la especie Aphytis melinus DeBach, parasitoide más eficaz en otros países. Junto a estas dos especies se ha verificado el establecimiento de Aphytis lingnanensis Compere en Castellón, tras repetidas sueltas, así como se ha descrito la presencia de dos nuevas especies de parasitoides sobre A. aurantii: Aphytis hispanicus (Mercet), parasitoide habitual de Parlatoria pergandii (Comstock) (Hem.; Diaspidadae) pero no de A. aurantii en España; y una especie que podría tratarse de un nuevo taxón para la ciencia y que hasta el momento de su próxima descripción se ha denominado Aphytis sp. grupo lingnanensis. De esta especie destacan como características principales la pigmentación casi absoluta de la pupa (fundamentalmente cabeza y tórax), la exuvia también oscura y la crénula solapada en el adulto. Junto a este grupo de ectoparasitoides, también se ha realizado la introducción de dos nuevos endoparasitoides del piojo rojo de California en la península Ibérica, dentro de un programa de control biológico clásico: Comperiella bifasciata (Howard) (Hym.; Encyrtidae) y Encarsia perniciosi (Tower) (Hym.; Aphelindae). Sólo se ha establecido la segunda especie en Castellón, tras ser transferida su cría al insectario de Sanidad Vegetal de Almazora (Castellón) y en colaboración con la unidad de entomología del Instituto Valenciano de Investigaciones Agrarias. Durante el periodo de estudio también se ha localizado a Comperiella lemniscata Compere y Annecke (Hym.; Encyrtidae), nueva especie de endoparasitoide de Chrysomphalus dictyospermi (Morgan) (Hem.; Diaspididae) en España.Se ha verificado que A. chrysomphali en campo parasita fundamentalmente cochinillas macho, lo cual --y tal y como se demuestra en la tesis-- afecta negativamente al tamaño del parasitoide, a su longevidad y fecundidad. Sin embargo, en condiciones de laboratorio, esta especie prefiere un hospedador de mayor tamaño como la hembra joven, y por tanto la elección en campo de un hospedador de menor calidad obedece a cuestiones de tipo ecológico. Entre estas variables, podrían ser determinantes aspectos como la estructura de la población de la cochinilla en campo donde predominan estados inmaduros, hecho que a su vez podría ser responsable de la baja densidad de la población de A. melinus que requiere estados más avanzados para su correcto funcionamiento.Por otro lado, se ha observado que A. chrysomphali está infectada por la bacteria endosimbionte Wolbachia. En este trabajo se demuestra como esta bacteria en A. chrysomphali induce la partenogénesis telitoca, de tal modo que si se elimina la bacteria mediante tratamientos antibióticos se revierte el porcentaje de sexos hacia la producción de una descendencia formada exclusivamente por machos. Además, a medida que disminuye la densidad de la bacteria en los progenitores, su fecundidad, y la supervivencia de los estados inmaduros, se ve reducida. Por otro lado, los machos obtenidos presentan un comportamiento de cópula normal a diferencia de las hembras, infectadas o curadas, que no se muestran receptivas e impiden la cópula, concluyendo que la reproducción partenogenética telitoca exhibida por la hembra es de tipo irreversible.

Abstract:
Si sono analizzate sperimentalmente e analiticamente alcune strategie di gestione dei flussi di potenza all’interno della microrete sperimentale presente nel Laboratorio del CIREA - UniBo Centro Interdi- partimentale di Ricerca per l’Energia e L’Ambiente con sede a Ravenna. In particolare é stato analizzato un modello matematico per la rappresentazione e previsione del voltaggio batteria , parametro che risulta essere strettamente legato al suo livello di carica. Tale tensione é funzione appunto dello stato di carica della batteria, dei parametri caratteristici della stessa e della corrente erogata. Con tale modello si é caratterizzato il pacco batterie presente in laboratorio analizzando l’accuratezza del modello sui livelli di tensione. Inoltre è stata analizzata la fase di carica del pacco batterie, concentrando lo studio sull’efficienza di tale processo e in generale su quella del completo ciclo di carica scarica. E' stato analizzato un modello matematico che descrive tale efficienza di carica in funzione dello stato di carica attuale e della corrente disponibile alle batterie e tramite i dati sperimentali ho definito i valori del rendimento di carica delle prove effettuate, analizzando alcune possibili strategie per l’ottimizzazione del processo. Piú in dettaglio, ho valutato diversi valori dei rendimenti ottenibili per diverse condizioni operative. L’analisi ha dimostra- to, tra l’altro, che data la potenza disponibile proveniente dai pannelli solari al momento delle prove, una riduzione della suddetta potenza in ingresso alla batteria nelle fasi finali di carica, puó migliorare il rendimento globale del ciclo carica-scarica. La riduzione di potenza in ingresso é giustificata dal fatto che il modello per l’efficienza di carica definisce una corrente di ottimo, funzione dello stato di carica SOC, che garantisce un rendimento minimo di carica imposto a priori. Nelle prove da me effettuate tale paramentro é stato fissato al 97%.

Abstract:
Madame de La Fayette's La Princesse de Clèves was written between 1671 and 1677 at a time in French history when women's rights were beginning to find a voice in the "salons" of a few prominent female members of the leisure class. Although an immediate success with the reading public of seventeenth-century France, Madame de La Fayette's novel attracted a great deal of critical attention of the type that did not convince her to cast off her anonymity and come forth as the rightful author. As a roman d'analyse, La Princesse de Clèves stepped out of the conventions of vraisemblance and bienséance (plausibility and propriety) by the manner in which it followed the rites of passage of a young girl from maidenhood to self-evolved womanhood through the use of the medium of human relationships. In taking the idea of a psychological study one step further, into the realm of mythology, the reader is able to gain greater insight into the motivational forces at work within the principal character's psyche. Madame de Clèves' mythical journey towards a greater sense of self-awareness is activated by a deep-seated need, found in varying degrees in both women and men but in general more predominantly in women, to establish and maintain positive, creative relationships with others. This need goes back to the essential and eternal bonding between mother and daughter and the more tenuous bonding between mother and son. Placed within a mythological framework, the princesse's fictional development can be described through the intermediary motif of the quest. The princesse, unconsciously at first, sets out on a search for Self - a search for the centre of undistorted recognition of one's essence. She is stirred to action by feelings of dissatisfaction, loss and incompleteness arising from deep within her being. The initial phase of the journey entails a pulling away from the intense Mother bonding (without totally separating from it) by means of initiation through the "masculine" (her platonic lover Nemours). She is then able to accept and appreciate the parts of her inner nature she had been taught to avoid as a young girl (passion, moodiness, rage) and begin the difficult task of redeeming the Feminine within, in both her beauty and her destructiveness. During the process of looking at her own life, her own immediate past, the princesse finds herself drawn to the myths of a more distant past as well. She comes in touch with her mythical beginnings, with the unconscious dreams of an ancient people who, unlike their successors, were more at peace with their connection to life's mysterious truths personified by the oldest revered divinity: the ancient Great Goddess, "Union of all things related one to another." The result for Madame de La Fayette's heroine is a self-realized existence far from the culturally dictated role that society had allotted for her. In her moving away from the French court to the world of wholeness and integrity of country home and convent, the princesse is able to taste the fruits of freedom. She is able to become filled with the "goddess energy" of all aspects of her life and join past and future in her personal quest to bring inner healing to herself and to others.

Sin embargo, su compleja biología y comportamiento ha obstaculizado en muchos casos evaluar su verdadero papel como agentes de Control Biológico. En su mayor parte, los estudios sobre depredadores se han concentrado en las relaciones simples entre los depredadores especialistas y sus presas ya que estos sistemas son más fáciles de parametrizar. No obstante, existe un creciente interés en el control ejercido por los depredadores generalistas, debido a su capacidad de mantener las densidades de presas en equilibrios estables en formas no dependientes de la densidad de las mismas. Los estudios realizados en este trabajo se localizaron en parcelas de clementinos ubicadas en la Provincia de Valencia y Castellón. Los estudios de laboratorio se llevaron a cabo en las instalaciones del Instituto Valenciano de Investigaciones Agrarias (IVIA). En el primer estudio presentado, se reevalúa la importancia de la depredación como factor de mortalidad biótica de una plaga clave bajo un sistema de control biológico por conservación. Para éste, se tomó como modelo al piojo rojo de California, Aonidiella aurantii, en el cultivo de clementinos. Por medio de la utilización de técnicas de exclusión a campo y de detección de ADN de la presa en el contenido intestinal de los depredadores registrados, mediante la técnica de PCR, se logró dilucidar cómo un rico complejo de depredadores generalistas y estenófagos indígenas o naturalizados son los principales factores de mortalidad de la plaga en estudio. Como segundo objetivo se planteó identificar en otro grupo de plagas claves del cultivo de clementinos, cuáles son los factores limitantes y reguladores que no permiten que las poblaciones de estos fitófagos superen el umbral de daño económico. A través de un muestreo semanal de las poblaciones de pulgones, de A. spiraecola y A. gossypii, y de sus depredadores asociados, como también de las observaciones fenológicas de los clementinos y utilizando información meteorológica de la zona, se evaluó la dinámica de los niveles de infestación producidos por pulgones. El análisis de la información obtenida nos permite considerar que la única variable que limita el desarrollo de las poblaciones de estas plagas es el estado fenológico de su huésped. También se confirma que los depredadores son un importante factor regulador en el control de las poblaciones de pulgones. Entre estos depredadores, los micrococcinélidos podrían tener el papel más significativo. Según nuestros datos podemos considerar que, para que exista un buen control de las poblaciones de pulgones en la cuenca mediterránea, deben generarse las condiciones favorables para que el hospedero limite el desarrollo de las colonias de estas plagas y que los depredadores actúen regulando sus poblaciones. Debido a que se registran dos especies de pulgones como plagas claves en los clementinos (A. spiraecola y A. gossypii) y se identifican dos especies de micrococcinélidos (Scymnus subvillosus y S. interruptus) como sus depredadores más abundantes y de mayor relevancia, en un tercer objetivo se evaluó en laboratorio y campo el efecto de estas presas sobre los parámetros de desarrollo, supervivencia y reproducción de estos depredadores. De esta forma, la presente tesis reevalúa el papel de la depredación como factor regulador en las poblaciones de las plagas clave en los agroecosistemas de cítricos e investiga los mecanismos ecológicos y biológicos que llevan al éxito o al fracaso de este importante componente de mortalidad biótica. Los resultados presentados aquí apoyan firmemente un cambio de paradigma en los enfoques de control biológico que se está llevando a cabo en los últimos años, destacando la importancia de comprender el contexto ecológico en el que se desarrolla el control biológico
[CAT] Dins dels enemics naturals de plagues als agroecosistemes, els depredadors han sigut considerats com un dels grups de major importància. No obstant això, la seua complexa biologia i comportament ha obstaculitzat en molts casos l¿avaluació del seu vertader paper com a agents de control biològic. En la seua major part, els estudis sobre depredadors s'han centrat en les relacions simples entre els depredadors especialistes i les seues preses, ja que aquests sistemes són més fàcils de parametritzar. Malgrat açò, existeix un creixent interès en el control exercit pels depredadors generalistes, a causa de la seua capacitat de mantenir les densitats de preses en equilibris estables en formes no depenents de la densitat d¿aquestes. Els estudis realitzats en aquest treball es localitzaren en parcel·les de clementins situades en la Província de València i Castelló. Els estudis de laboratori es van dur a terme en les instal·lacions de l'Institut Valencià d¿Investigacions Agràries (IVIA). En el primer estudi presentat, es reevalúa la importància de la depredació com a factor de mortalitat biòtica d'una plaga clau sota un sistema de control biològic per conservació. Per a aquest, es va prendre com a model el poll roig de Califòrnia, Aonidiella aurantii, al cultiu de clementins. Per mitjà de la utilització de tècniques d'exclusió a camp i de detecció d'ADN de la presa en el contingut intestinal dels depredadors registrats, mitjançant la tècnica de PCR, es va aconseguir dilucidar com un ric complex de depredadors generalistes i estenófagos indígenes o naturalitzats són els principals factors de mortalitat de la plaga en estudi. Com a segon objectiu es va plantejar identificar en un altre grup de plagues clau del cultiu de clementins, quins són els factors limitants i reguladors que no permeten que les poblacions d'aquests fitófags superen el llindar de dany econòmic. A través d'un mostreig setmanal de les poblacions de pugons, de A. spiraecola i A. gossypii, i dels seus depredadors associats, també així com de les observacions fenológiques dels clementins i utilitzant informació meteorològica de la zona, es va avaluar la dinàmica dels nivells d'infestació produïts per pugons. L'anàlisi de la informació obtinguda ens permet considerar que l'única variable que limita el desenvolupament de les poblacions d'aquestes plagues és l'estat fenológic del seu hoste. També es confirma que els depredadors són un important factor regulador en el control de les poblacions de pugons. Entre aquests depredadors, els micrococcinélids podrien tindre el paper més significatiu. Segons les nostres dades podem considerar que, perquè existisca un bon control de les poblacions de pugons en la conca mediterrània, han de generar-se les condicions favorables perquè l'hoste limite el desenvolupament de les colònies d'aquestes plagues i que els depredadors actuen regulant les seues poblacions. Per tant, una estratègia de gestió del cultiu que afavorisca l'aparició dels micrococcinélids de forma primerenca i abundant, podria contribuir al fet que les poblacions d'aquestes plagues clau no excedisquen el llindar de dany econòmic i d'aquesta manera reduir l'ús de pesticides per al seu control. Com que es registren dues espècies de pugons com a plagues clau en clementins (A. spiraecola i A. gossypii) i s'identifiquen dues espècies de micrococcinélids (Scymnus subvillosus i S. interruptus) com els seus depredadors més abundants i de major rellevància, en un tercer objectiu es va avaluar en laboratori i camp l'efecte d'aquestes preses sobre els paràmetres de desenvolupament, supervivència i reproducció d'aquests depredadors. La informació generada en aquest estudi, proporciona indicis sobre les relacions entre les espècies de Scymnus amb les espècies de pugons que es troben als cultius de clementins de la conca mediterrània. Es reafirma la teoria que la qualitat de la dieta influeix en els paràmetre
[EN] Predators have been considered as one of the most important groups of pest natural enemies in agroecosystems. However, their complex biology and behaviour have hindered in many cases evaluating its true role as biological control agents. Studies on predators have mostly focused on the simple relationships between specialist predators and their prey since these systems are easier to parameterize. Though, there is a growing interest in the control exerted by generalist predators owing to their ability to keep prey densities in stable equilibrium in ways not dependent on their density. The importance of predation as a biotic mortality factor of key citrus pests in systems under conservation biological control management strategies was assessed. The California red scale, Aonidiella aurantii, was used as a model pest in clementine citrus groves. Through the use of field exclusion techniques and PCR detection of prey DNA in the gut content of predators, it was found that a rich complex of indigenous and naturalized generalist and stenophagous predators are the main mortality factor of this pest. Limiting and regulating factors modulate severity of pest infestations in agroecosystems. The second objective was to identify how these variables explain the current patterns of spring aphid infestations in clementine citrus crops of the Mediterranean basin. Populations of Aphis spiraecola and A. gossypii as well as of their associated predators were sampled weekly. Phenological changes in citrus trees were also observed. Abiotic variables (temperature and precipitation) influence was also taken into account. The analysis of the relationships between all these variables showed that the only factor able to limit aphid infestations under Mediterranean conditions is the phenological state of their host. Nevertheless citrus phenology was found to be strongly mediated by temperature. Results also confirmed that predators are an important regulatory factor of aphid demography, being micrococcinellids the only natural enemies found to have a significant role. According to our study, in order to have effective aphid control in clementine citrus of the Mediterranean basin, favourable conditions must be generated so that the host limits the development of aphid colonies and predators exhibit their highest regulation potential. A crop management strategy that favours the presence of micrococcinellids early in the season could contribute to keep the populations of these key pests more frequently under their economic thresholds thus reducing the frequency of pesticide applications for their control. Because two species of aphids are registered as key pests in clementines (A. spiraecola and A. gossypii) and two species of micrococcinellids of the same genus (Scymnus subvillosus and S. interruptus) are identified as the most abundant and important aphid predators, in a third objective it was evaluated under laboratory and field conditions the effect of these preys on the parameters of development, survival and reproduction of these predators as well as on the predator demography. The information generated in this study provides essential clues to understand the relationships between the two Scymnus species and the aphid species found in clementine crops in the Mediterranean basin. The theory that the quality of the diet influences the development, fertility and population parameters of the predators was reaffirmed. In this case, A. gossypii is considered the most suitable for the Scymnus species. In conclusion, the present thesis reassess the role of predation as a regulating factor of key pests in citrus agroecosystems and inquires into the ecological and biological mechanisms laying behind the success and failures of this important biotic mortality component of citrus phytophagous. The knowledge generated through these studies will permit to develop more effective conservation biological control strategies for citrus agroecosystems.

Abstract:
Tout au long de la chronologie de l'oeuvre de mme de lafayette, plusieurs themes sont reconnus, comme des composantes principales: la peinture de la cour, l'amour, la retraite et la mort. Cette derniere, malgre sa presence importante chez cet ecrivain, n'a pas encore ete etudiee dans l'ensemble de sa creation. Cette etude est destinee a decouvrir pourquoi et comment les mentalites et les pensees funebres de l'epoque se refletaient sur l'activite creative et litteraire d'une femme et son recit de mort. Dans les textes romanesques de meme que ceux de memoires, la destinee des personnages est representee par leur maniere de mourir: la mort sociale, la mort solitaire et sans dignite, la mort absurde et violente, la belle mort. Or, l'amour est trop dangereux dans la societe de cour, ou le mariage se fait sans amour mais par interet. L'heroisme de l'age precedent n'existe plus pour les personnages, ce qui correspond bien a la vision pessimiste du monde au xviie siecle. Cependant, sans doute inspiree par la destinee et la mort de madame, la romanciere cree dans la princesse de cleves, une heroine qui cherche, malgre son destin tragique, a garder sa dignite humaine et gagner le repos de son ame en entrant dans une retraite edifiante pour renoncer a toutes choses du monde. Enfin, ses derniers memoires, rediges juste avant sa disparition, semblent etre son memento mori. L'oeuvre de la comtesse lui a permis de chercher son moi, qu'elle a trouve dans la pensee de la mort.

Abstract:
The California red scale Aonidiella aurantii is considered a key citrus pest. Parasitoids of genus Aphytis are the most important natural enemies of A. aurantii. In the Mediterranean basin, the native A. chrysomphali and the introduced A. melinus are the most abundant parasitoids of A. aurantii. The introduced has completely displaced the native A. chrysomphali in the south, whereas they coexist in the north-east of the Iberian Peninsula. We have used this well-known host-parasitoid system to investigate some gaps on the behavioural ecology of hymenopteran parasitoids, which have been exposed in the introduction. This knowledge will contribute to improve their use in biological control programs, especially in the case of A. aurantii in the Mediterranean basin.
El piojo rojo de California, Aonidiella aurantii, se considera una de las plagas de los cítricos más importante a nivel mundial. Los principales enemigos naturales de A. aurantii son los parasitoides del género Aphytis, siendo los más abundantes en la cuenca mediterránea el nativo Aphytis chrysomphali y el introducido A. melinus. En las zonas del sur de la Península Ibérica, A. melinus ha desplazado completamente al nativo A. chrysomphali, mientras que en el noreste ambos parasitoides coexisten. Durante el desarrollo de esta tesis, hemos utilizado este conocido sistema de parasitoides-hospedante para investigar algunos aspectos poco conocidos en la ecología del comportamiento de los parasitoides himenópteros, los cuáles han sido mencionados en la introducción de la tesis. Este conocimiento contribuirá a mejorar su uso en programas de control biológico, especialmente en el caso de A. aurantii en la cuenca mediterránea.

Abstract:
Cette thèse propose conjointement d’étudier l’activité de grimpeurs en escalade glacière tout en développant des perspectives pour la conception. Pour cela, elle s’appuie sur un programme de recherche empirique d’anthropologie cognitive énactif et un programme de recherche technologique ergonomique d’évaluation des situations d’appropriation. La première partie de ce travail s’attache à décrire la construction de « l’objet piolet » en faisant le lien entre innovation et pratique tout en déterminant la relation entre pratiquant et objet technique afin de construire les bases d’une « pensée de la technique » nécessaire à la constitution d’un programme de recherche technologique pour la conception. La deuxième partie poursuit une visée a) épistémique en produisant des connaissances sur le rôle de médiation joué par les piolets dans l’activité des glaciéristes, et b) transformative, en développant la situation d’appropriation comme objet de conception. Pour ce faire, nous mettons en avant a) l’utilisabilité des objets techniques (étude 1) puis b) l’appropriabilité de ces derniers (étude 2) pour ensuite c) mettre en oeuvre l’objet théorique cours d’in-formation en exploitant des données issues de l’activité soumise et non soumise à la conscience pré-réflexive pour documenter l’appropriation (étude 3). La troisième partie, quant à elle, poursuit une visée transformative et s’attarde à définir des critères pertinents pour développer le programme de recherche et enrichir la conception
The aim of the present thesis is twofold: first, it gives an overview onice climbers’ activity, based on an enactive empirical research program of cognitive anthropology, while developing a technological research program toevaluate appropriation situations and perspectives for design. The first part of this work focuses on the link between innovation and practice while identifying the relationship between the climbers and the technical object in order to build a technological research program focusing on the appropriation of objects. The second part is an epistemic work inculding two steps: a) to produce knowledge on the mediation role of ice axes for novice climbers and b) to develop design objects for the improvement of the research program. To this end, the usability of artifacts is highlighted (study 1) as well as the appropriability of artifacts (study 2) and then c) the theoretical object course of information is implemented using data from the activity subject and non-subject to pre-reflective consciousness to document the appropriation (study 3). The third section, however, seeks to bring about change and focuses to define the relevant criteria for the research program development and to improve the design

Abstract:
Au 17e siècle, la Princesse de Clèves est une contribution incontestable au développement du genre romanesque. L'état des débats actuels sur l'art romanesque inspire notre tentative de lecture et le but de notre recherche. Elle concerne la logique que l'auteur confère aux sous-ensembles du roman et les rapports entre structures globale et partielles. Nous posons les questions suivantes : comment naît chaque récit? Comment s'agence-t-il? En quoi participe-t-il à la composition du roman? Nous essayons de mettre en évidence l'idée que chacun d'entre eux, même à première vue inutile, est indispensable à la construction générale. Nous examinons comment les récits secondaires étrangers en apparence à l'intrigue principale s'en approchent progressivement pour s'y imbriquer. Puis nous examinons l'avancée de l'intrigue centrale se détachant sur l'arrière-plan des récits secondaires. Nous observons qu'infrastructure des récits secondaires et superstructure du récit principal s'entrelacent organiquement, aussi indissociables que l'ombre et la lumière. Ainsi se dégage une logique de composition fort minutieuse qui répond aux questions posées. La modernité de l'auteur se justifie par la primauté accordée au système constructif
In the seventeenth century. The Princess of Cleves is a major contribution to the development of the genre of the noval. This research is an attempt at a reading based in as far as possible on the perspectives which the present state of reflection on the art of the novel has opened up. It seeks to describe the logic which the author confers on the underlying form of the novel and the relation-ship between the overail structure and its constituent parts. The first part is concerned with the process of interweaving whereby the secondary stories, apparently unconnected with the main plot, are slowly drawn into it and merge with it. The second part is concerned with how the principal stories which form the main plot are united together as they emerge from the background of secondary stories during the development of the novel. Through this research. It can be observed how in this novel the secondary stories and the main stories interiace organically and become interdependent. It is concluded that the attitude of its creator, mme de lafayette, who seemed to consider a novel as a litterary construction, enabled her novel to achieve modernity

Abstract:
Le mot et le theme de "desir" saturent l'oeuvre narrative de charles pinot - duclos (1742- 1761 ) tiennent a la predation et au libertinage en subvertissant le modele de la princesse de cleves. . Le "libertinism", selon les reperages de robert darnton a propos de la litterature clandestine, le"sensualisme", la pensee contingente, avec l'enracinement novateur dans le point de vue individuel, les assises autobiographiques du roman-memoires au xviii e siecle, la langue, favorisent le "discours" de duclos, capteur du discours libertin, par la classe montante qu'il represente, sa mobilite litteraire. Le "desir", sceptique, feministe, de l'auteur, a l'instar des salons litteraires de l'epoque, affirme le "desir" comme theatre et representation, resolution du bonheur et son "discours", parfois erotique et feroce, annonciateur du marquis de sade, mais nullement pornographique, reduit au discours amoureux et a ses strategies, sur un mode et une ecriture deja stendhaliens, repond aux emergences naturelles du desir par le talent litteraire et l'emergence" dans la vie. Nous avons procede a un releve des emergences du "desir", a une exploration analytique des strategies discursives , en alignant sur la production lineaire romanesque de l'auteur, la progression de sa reflexion et mise a distance moraliste la these repose sur la conflagration de deux textes porteurs, le roman archetype de la princesse de cleves , et l'oeuvre narrative de charles pinot duclos, et propose un eclairage, contournant et rejoignant les travaux et analyses de jacques brengues
The word and the theme of "desire" saturate the narrative works of duclos, and relate to the theme of predation and libertinism in the subversion of the model provided by la princesse de cloves. "libertinism", as designated by robert darnton in clandestine literature, "sensualism", contingent thought, with its original rooting in the individual point of view, the autobiographical foundation provided by novel-memoirs in the 18th century, the language, all favour the "discourse" of duclos, which captures the essence of libertin discourse, the rising social milieu it represents and its literary mobility. The sceptical and feminist "desire" of the author, like the literary salons of the period, affirms desire as theatre and representation, resolution of happiness; and his "discourse", sometimes erotic, sometimes ferocious, announcing that of sade, but not pornographic, reduced to the discourse of love and to love's strategies, providing a literary model which will be followed by stendhal, responds to the natural emergence of desire by the demonstration of literary talent and "emergence" in life. We have recorded the occurrences of "desire" and analysed the rhetorical strategies at work, comparing the novels written by the author in linear, chronological order with the progression of his thought and moralist mise a distance. The thesis is based on the conflagration of two main texts, the archetypal novel of la princesse de cleves and the narrative works of duclos, and proposes a commentary which meets with the works and analyses of jacques brengues

Abstract:
Cette etude propose, plus sous la forme d'un essai que d'une these, une approche de la casuistique amoureuse et de la rhetorique du desir dans l'oeuvre romanesque de madame de lafayette. Elle insiste particulierement sur le premier grand roman de ce corpus, zaide, anterieur a la princesse de cleves. Que signifient les questions d'amour issues de la preciosite? ont-elles constitue, en leur temps, une reponse linguistique aux passions du coeur? des elements de reponse sont apportes, dans un premier temps, a travers quatre courts chapitres ayant trait a la sensibilite litteraire, puis a travers une double hypothese portant sur la genetique de l'amour et la genese du recit, ensuite sous la forme d'une analyse du concept de casuistique et de quelques fragments de "cas", enfin par l'examen du "discours amoureux" propre a madame de lafayette, discours qui constitue une veritable rhetorique du desir. Ces elements de reponse sont, en conclusion, replaces dans une perspective morale. Destinee individuelle et univers romanesque prennent leur place dans l'histoire des sensibilites
This study, in essay rather than thesis form, suggests an approach to the love casuistry and rhetoric of desire in the novels of madame de lafayette. It deals principally with the first important novel, zaide, written before la princesse de cleves. What do questions about love stemming from preciosity signify? did they form, during this period, a linguistique response concerning passions of the heart? this question is first adressed in four short chapters dealing with literary sensibility, then by a double hypothesis focussing on the generic of love and the genesis of narrative, followed by an analysis of the concept of casuis try along with "case studies", and, finally, by a study of mme de lafayette's own discourse of love, a discourse which forms a veritable rhetoric of desire. These issues are, in conclusion, put into a moral perspective. Individual destiny and the universe of the novel assume their place in the history of sensibilities
