Previous issue date: 2017-08-31 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Brazil is one of the 5 most megadiverse countries in the world, presenting 14% of all the biodiversity known worldwide. Brazil also has a greater tropical vegetation covering the world, presenting a high number of endemic species, becoming one of the most important countries in the world for investments in bird conservation. The district of Cacaria, in the municipality of Pira?, Rio de Janeiro, Brazil, has an extensive vegetation cover area, but is affected by local cattle breeding, as well as other anthropogenic actions. Birds can have a high diversity of parasites, such as ectoparasites, helminths and coccidia. Coccidian parasites are the main cause of enteritis, behavioral and reproductive changes in most species of birds. . Coccidia studies are relevant both to animal health and to knowledge of the biodiversity of these parasites. In this context, the objective of this study was to examine the feces of wild birds captured in fragments of Atlantic Forest in the district of Cacaria, in southeastern Brazil, to identify and quantify the coccidian parasites that were present, besides relating them to some ecological characteristics of birds. 14 expeditions were carried out on three fragments of Atlantic Forest in Cacaria, resulting in the capture of 143 birds, with 20 of them positive for coccidia. Among the positive samples, coccidia of Isospora and Eimeira classification were found in 12 species of birds. These coccidia were identified according to the literature, species of coccidia not described in the literature until the present moment were considered morphotypes. There was no relation between the bird species and the positive samples, with their respective oopds (Oocyst by defecation). Regarding the ecological characteristics, only living habits in forest environments were significant, showing that the birds of forest environments are less susceptible to infection. Regarding eating habits, there were no significant results / O Brasil ? um dos 5 pa?ses mais megadiversos do mundo, apresentando 14% de toda a biodiversidade conhecida mundialmente. O Brasil tamb?m tem uma maior vegeta??o tropical cobrindo o mundo, apresentando um elevado n?mero de esp?cies end?micas, tornando-se um dos pa?ses mais importantes do mundo para investimentos em conserva??o de aves. O distrito de Cacaria, no munic?pio de Pira?, Rio de Janeiro, Brasil, tem uma extensa ?rea de cobertura vegetal, mas ? afetado pela cria??o de gado local, al?m de outras a??es antr?picas. As aves podem ter uma alta diversidade de parasitas, como ectoparasitas, helmintos e coccidia. Os parasitas coccidianos s?o a principal causa de enterite, altera??es comportamentais e reprodutivas, na maioria das esp?cies de aves. Os estudos de coccidia s?o relevantes tanto para a sa?de animal quanto para o conhecimento da biodiversidade desses parasitas. Neste contexto, o objetivo deste estudo foi examinar as fezes de aves silvestres capturadas em fragmentos de Mata Atl?ntica no distrito de Cacaria, no sudeste do Brasil, para identificar e quantificar os parasitas coccidianos que estavam presentes, al?m de relacion?-los a algumas caracter?sticas ecol?gicas das aves. Foram realizadas 14 expedi??es em 3 fragmentos de Mata Atl?ntica em Cacaria, resultando em captura de 143 aves, com 20 delas positivas para cocc?dios. Dentre as amostras positivas foram encontradas cocc?dios de classifica??o Isospora e Eimeira, em 12 esp?cies de aves. Esses cocc?dios foram identificados de acordo com a literatura, as esp?cies de cocc?dios n?o descritas na literatura at? o presente momento foram consideradas morfotipos. N?o se obteve rela??o entre as esp?cies de aves e as amostras positivas, com seus respectivos oopds (Oocisto por defeca??o). Em rela??o as caracter?sticas ecol?gicas, apenas h?bitos de viv?ncia em ambientes florestais foi significante, apresentando que as aves de ambientes florestais s?o menos suscept?veis a infec??o. J? em rela??o aos h?bitos alimentares, n?o se obteve resultados significativos.

Morphologie, évolution latérale et signification géodynamique des discontinuités sédimentaires. Exemple de la marge Ouest du Bassin du Sud-Est (France)HAMON, Youri 16 December 2004 (has links) (PDF)
La série liasique du Seuil Caussenard, située sur la marge Sud-Ouest du Bassin du Sud-Est Français est constituée de dépôts dolomitiques hettangiens épais, suivis de faciès à dominante calcaire, d'âge Hettangien supérieur à Lotharingien. Cette série carbonatée est coiffée par un niveau condensé durci, associé à de l'érosion, qui marque la transition Lias calcaire – Lias marneux (Toarcien). Le levé banc par banc de onze coupes géologiques balayant l'intervalle Sinémurien s.l., a permis de montrer que cette série s'organise en deux ensembles sédimentaires correspondant à deux types de plates-formes carbonatées qui se relaient au cours du temps. <br />Le premier ensemble voit surtout se développer des faciès de faible énergie (de replat de marée, de lagune). Le second ensemble voit la disparition des faciès dolomitiques et la multiplication des faciès ouverts, profonds. L'étude régionale de la répartition latérale de ces faciès a montré des variations rapides et sur de très faibles distances (de la centaine de mètres au kilomètre). De plus, il s'avère impossible de définir une réelle polarité « amont-aval » entre une zone continentale et un domaine marin franc à l'échelle régionale et il est rapidement apparu comme impossible de hiérarchiser les faciès sédimentaires le long d'un profil de dépôts de plate-forme barrée classique. Nous proposons donc un nouveau modèle de dépôts basé sur ces observations. La région de Lodève est envisagée comme une mosaïque de zones hautes, très peu profondes, à caractère inter- à supratidal, entre lesquelles peuvent se développer des zones plus profondes, infralittorales à circalittorales. Le contexte tectonique local, caractérisé par la présence de nombreux réseaux de failles SW-NE et NW-SE, dont certaines ont joué de façon synsédimentaire, contrôle la formation de ces zones hautes et basses, et affecte la sédimentologie et l'épaisseur de la série du Lias calcaire.<br />Cette première phase de l'étude a permis de définir le contexte géodynamique régional, dans lequel se développent les nombreuses discontinuités sédimentaires. En se basant sur différents critères, d'ordre morphologique, biologique ou diagénétique, les discontinuités ont été classées en quatre grandes catégories : surfaces d'émersion (surfaces karstiques, paléosols, coupelles de dessiccation) ; niveaux de condensation de différents types (softgrounds, firmgrounds, différents types de hardgrounds) ; surfaces d'érosions sous-marines ; surfaces composites présentant en association des critères d'érosion, d'émersion et de condensation. L'étude sédimentologique et le découpage en unités génétiques ont permis de proposer des corrélations régionales dans ces dépôts du Lias et d'examiner le « comportement latéral » des différentes discontinuités limitant ces unités (continuité, changement de morphologie ou de nature, maturité, etc...). Il a également été possible de discuter de leur répartition verticale dans la série en fonction du cadre séquentiel et suivant le contexte paléotopographique et tectonique local.<br /><br />Les corrélations réalisées entre la série du Seuil Caussenard, la marge Ardéchoise et la marge de Sologne (Bassin de Paris) ont enfin permis de déterminer l'existence de discontinuités majeures. Le hardground au sommet du Lotharingien marque un évènement tectonique pluri-régional (connu sous le nom de crise Lotharingienne) enregistré dans les Causses, le Quercy ou encore le Bassin de Paris. La transition Hettangien-Sinémurien bien visible dans le Bassin de Paris ne se marque, sur le Seuil Caussenard, que par un « niveau diagnostique », au sein duquel s'observent plusieurs surfaces karstiques.

Decoding lysine-11 signals in ubiquitinationGrice, Guinevere January 2018 (has links)
The diverse outcomes of ubiquitination primarily relate to the flexibility of ubiquitin in forming homo- or heterotypic chains on each of its seven lysine residues which in turn stimulate distinct downstream signaling pathways. These ubiquitin signals must be selectively initiated on the substrate protein and subsequently decoded to facilitate the desired cellular function. These initiation and decoding steps often involve additional post-translational modifications and ubiquitin receptor proteins, but the enzymes and ubiquitin chains involved for many ubiquitinated substrates are not clear. Here, I have explored the initiation and decoding of ubiquitin signals, focusing on lysine-11 (K11) linked polyubiquitin chains and their role in protein degradation. I established in vitro assays to understand how K11-chains are decoded and whether these chains act as a signal for proteasome-mediated degradation. Pure homotypic K11-chains did not bind the proteasome or its associated ubiquitin binding proteins, but did bind to the mitophagy ubiquitin receptors, MyosinVI and TAX1BP1. Heterotypic K11/K48 linkages not only bound the proteasome but also stimulated degradation of the cell cycle substrate, cyclin B1. To further explore the functions of K11-chains I focused on the hypoxia inducible transcription factor (HIF) pathway, as K11-ubiquitination had been implicated in proteasome-independent degradation of the transcription factor. I established an in vitro assay to initiate HIF ubiquitination, via prolyl hydroxylation, and determine the type of ubiquitin chains involved. Recombinant HIF isoforms were rapidly hydroxylated when incubated with cell extracts. Moreover, the levels of iron and small molecule metabolites within the lysates regulated HIF hydroxylation. However, this hydroxylation was insufficient to reproducibly promote HIF ubiquitination or determine the ubiquitin chains involved. While the nature of the polyubiquitin chains formed in the HIF pathway remain elusive, my studies identify distinct roles for homotypic and heterotypic K11-polyubiquitination in proteasome-mediated degradation.

Previous issue date: 2015-04-20 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico - CNPq / As brom?lias constituem importante microhabitat para a herpetofauna, pois s?o
bastante utilizadas como abrigo contra predadores, al?m de sua arquitetura foliar
possibilitar manuten??o de umidade e temperatura relativamente constantes no seu
interior, compondo um ambiente favor?vel para os anf?bios e r?pteis, especialmente em
?reas sob estresse h?drico. No entanto, os estudos que tratam dessa rela??o ainda s?o
incipientes e mais concentrados sobre as brom?lias fitotelmatas acumuladoras de ?gua.
No caso das brom?lias rup?colas n?o fitotelmatas do g?nero Encholirium, que se
desenvolvem em afloramentos rochosos e abrigam esp?cies de regi?es semi?ridas como
as Caatingas, as rela??es animais-plantas s?o praticamente desconhecidas. Nesse
contexto, este estudo teve como objetivos estudar a fauna herpetol?gica habitante das
brom?lias macambiras, Encholirium spectabile, analisando a ocupa??o e uso destas
brom?lias pelos diferentes t?xons, e a ecologia comportamental do largarto Psychosaura
agmosticha, buscando identificar os fatores associadas com esta rela??o estrita em ?rea
de Caatinga. Uma ampla revis?o da literatura mundial acerca do tema lagartos em
brom?lias subsidiou este estudo sob a perspectiva ecol?gica dessa associa??o. O trabalho
de campo foi realizado na Fazenda Tanques, munic?pio de Santa Maria/RN, mesorregi?o
do Agreste potiguar, com as observa??es e/ou coletas diurnas e noturnas efetuadas
mensalmente, durante tr?s dias consecutivos, de Janeiro de 2011 a Agosto de 2012,
totalizando 450 horas.homem de esfor?o amostral. Registraram-se dezesseis esp?cies,
seis de lagartos (Fam?lias Mabuyidae, Tropiduridae, Gekkonidae e Phyllodactylidae), seis
de serpentes (Fam?lias Boidae e Dipsadidae) e quatro de anf?bios da Fam?lia Hylidae. O
efeito da borda da mata sobre a distribui??o das esp?cies ao longo do afloramento foi
significativo, com a maioria das esp?cies encontradas nas bordas do afloramento.
Constataram-se diferen?a significativa entre alguns pares de esp?cies com rela??o ao uso
2
das brom?lias, e sobreposi??o de nicho quase total no uso de microhabitat. 62.5% das
esp?cies s?o de h?bito noturno e utilizaram essas plantas para abrigo, reprodu??o e
alimenta??o. Quanto ?s rela??es entre o lagarto Psychosaura agmosticha e as brom?lias
macambiras, foram registrados os comportamentos de termorregula??o e de forrageio nas
esta??es seca e chuvosa. Os per?odos de atividade foram concentrados entre 07 e 10 h e
entre 15 e 17 horas nas duas esta??es, demostrando um padr?o claramente bimodal. A
esp?cie usou basicamente as folhas verdes e n?o houve diferen?as significativas entre
machos e f?meas na utiliza??o das brom?lias. Associa??es positivas foram encontradas
entre a temperatura do corpo e temperaturas das brom?lias e do ar. Esta esp?cie passou
em m?dia 1.95 ? 3.8% do tempo em movimento (PTM) e se movimentou em m?dia 0.36
? 2.1 segundos por minuto (MPM), com diferen?as significativas entre as esta??es
chuvosa e seca para PTM, e tamb?m entre o tempo m?dio da parada e dura??o m?dia dos
movimentos, sendo considerada forrageadora sedent?ria. Psychosaura agmosticha, na
?rea estudada, ? bromel?cola, utilizando as macambiras principalmente para
termorregula??o e forrageio. Os resultados deste estudo destacam as brom?lias rup?colas
Encholirium spectabile como elementos chaves para a manuten??o de anf?bios e r?pteis
a ela associados, e uma clara associa??o vantajosa para a conserva??o dos grupos
envolvidos. / Bromeliads are an important microhabitat for the herpetofauna, for being widely
used as refuge from predators and their leaf architecture allows humidity maintenance
and relatively constant temperature inside, setting a favorable environment for
amphibians and reptiles, especially in areas under hydric stress. However, studies
addressing this relationship are still incipient and more concentrated in fitotelmatas
bromeliad. For non-fitotelmatas rupicolous bromeliads of the gender Encholirium, which
develops into rocky outcrops and contains species of semi-arid regions such as the
Caatinga, animal-plant relationships are almost unknown. In this context, this study aimed
to know the herpetological fauna inhabitant of macambiras bromeliads, Encholirium
spectabile, analyzing occupation and use of these bromeliads by different taxa, and the
behavioral ecology of the lizard Psychosaura agmosticha, seeking to identify factors
associated with this strict relationship in Caatinga. An extensive review of the world
literature on the subject ?lizards in bromeliads? subsidized this study from the ecological
perspective of this association. The field work was carried out at Fazenda Tanques,
municipality of Santa Maria / RN, mesoregion of Agreste Potiguar. The observations
and/or data collection in daytime and in the evening was conducted monthly during three
consecutive days, from January 2011 to August 2012, totaling 450 hour.man of sampling
effort. Sixteen species were registered: six lizards (Mabuyidae, Tropiduridae, Gekkonidae
and Phyllodactylidae Families), six snakes (Boidae and Dipsadidae Families) and four of
amphibians of Hylidae Family. The effect of the forest edge on the distribution of species
along the outcrop was significant, with most species found in outcrop edges. Significant
difference was found between some pairs of species concerning use of bromeliads, and
almost total niche overlap in the use of microhabitat. 62.5% of the species are nocturnal
and use these plants for sheltering, breeding and feeding. Regarding the relations between
4
the lizard Psychosaura agmosticha and macambiras bromeliads, behaviors of
thermoregulation and foraging in the dry and wet seasons were recorded. Activity periods
were concentrated between 7 and 10 am and between 3 and 5 pm in both seasons, showing
a clear bimodal pattern. The species basically used the green leaves and there were no
significant differences between males and females in the use of bromeliads. Positive
associations were found between body temperature and temperatures of bromeliads and
air. This species spent 1.95% ? 3.8 of the time moving (PTM) and moved on average 0:36
? 2.1 seconds per minute (MPM), with significant differences between the wet and dry to
PTM, and between the average time of stop and average duration of movements, being
considered a sedentary forager. Psychosaura agmosticha, in the study area, is
bromelicolous and uses macambiras primarily for thermoregulation and foraging. The
results of this study elevate the rupicolous bromeliads Encholirium spectabile as key
elements for the maintenance of amphibians and reptiles associated with it, and a clear
advantageous association for the conservation of the groups involved.

Previous issue date: 2014-02-27 / The theme and delimitation of this study comprises the sexual exploitation of adolescents in the municipalities of San Borja and Itaqui/ RS and its relationship with the social vulnerability of families assisted at the Specialized Protection and Assistance to Families and Individuals (PAEFI). The relevance of this research lies in the fact of giving visibility to the particularities of sexual exploration as a theme that needs further debate and appropriation by professionals who work in social policies and in the adolescent?s system for the guarantee of the rights of children and adolescents. The objective is to identify the relationship of sexual exploitation of adolescents with social vulnerability of families and how the PAEFI contributes to confront this phenomenon in order to provide insight to enhance public policies to address this form of violence. In this sense, the study seeks to answer the following problem: What are the dimensions of social vulnerability that adolescents in sexual exploitation are exposed and how these vulnerabilities are recognized and addressed by professionals linked to PAEFI? This is a qualitative research constructed from the critical dialectical framework. Regarding the procedures and techniques we used semi-structured interviews with application forms containing open and closed questions at seven ( 07 ) professionals who work at CREAS in the municipalities of San Borja and Itaqui, as well as for ( 01 ) female teenager, over 14 years of age served by PAEFI. Documentary analysis of professional documents related to the care and monitoring provided to fourteen ( 14 ) adolescent victims of sexual exploitation was also carried out. The free observation also composed the procedures and techniques, making himself present during the conduct of all research. Among the results, it is emphasized that prostitution was the most prevalent form of sexual exploitation attended by PAEFI; and the totality of cases were comprised by female victims. The main situations of social vulnerability present in the everyday life of families refer to illiteracy and low educational level of their parents, unemployment and precarious insertion in the labor market, low pay, poor housing conditions, weakening and breaking of family ties, history of sexual abuse, drug addiction, involvement of adolescents with older men in exchange for money and access to goods and services. One can also notice that the PAEFI lacks investment in human and material infrastructure. Among the challenges presented to the qualification of social policies in regard to combating sexual exploitation of children and adolescents highlights the need for training and qualification of the PAEFI as well as those working in different public services and policies that make the safety net for children and adolescents; incorporation of different forms of sexual exploitation (child prostitution, sex tourism, child pornography, trafficking for sexual exploitation) in the documents and reports used by professionals of PAEFI to characterize the demands of care related to this type of sexual violence; conducting an interagency and intersectoral work that focuses on social vulnerability and social needs that give rise to the sexual exploitation of children and adolescents. Based on the results and problematizations developed, this study confirms the thesis that social vulnerability situations experienced by families contribute to the production and reproduction of the relations of sexual exploitation of children and adolescents. These situations have several determinations, highlighting gender inequality and class, consumption as a means of social inclusion, the different manifestations of poverty, precariousness in the labor, family breakdown in the face of the reproduction of social and political relations that insufficiently seek answers to the demands and social needs of families. Such determinations do not occur in isolation. On the contrary, they are mutually related reaching a particular way the families of adolescents exposed to sexual exploitation. In other words, they constitute themselves as expressions of the conflict between capital and labor. / O tema e a delimita??o deste estudo compreendem a explora??o sexual de adolescentes nos munic?pios de S?o Borja e Itaqui/RS e sua rela??o com a vulnerabilidade social das fam?lias atendidas no Servi?o de Prote??o e Atendimento Especializado a Fam?lias e Indiv?duos (PAEFI). A relev?ncia dessa investiga??o reside no fato de dar visibilidade as particularidades da explora??o sexual enquanto tem?tica que carece de maior apropria??o e debate pelos (as) profissionais que atuam nas pol?ticas sociais e no sistema de garantia de direitos da crian?a e do adolescente. O objetivo da pesquisa ? identificar a rela??o da explora??o sexual de adolescentes com a vulnerabilidade social das fam?lias e de que forma o PAEFI contribui para o enfrentamento deste fen?meno, a fim de oferecer subs?dios para potencializar as pol?ticas p?blicas de enfrentamento a esta forma de viol?ncia. Nesse sentido, o estudo busca respostas para o seguinte problema: Quais as dimens?es de vulnerabilidade social que os (as) adolescentes em situa??o de explora??o sexual est?o expostos e como essas vulnerabilidades s?o reconhecidas e enfrentadas pelos profissionais vinculados ao PAEFI? Trata-se de uma pesquisa qualitativa, constru?da a partir do referencial dial?tico cr?tico. Em rela??o aos procedimentos e t?cnicas utilizou-se de entrevistas semiestruturadas com aplica??o de formul?rios contendo quest?es abertas e fechadas para sete (07) profissionais que trabalham junto ao CREAS dos munic?pios de S?o Borja e Itaqui, bem como para uma (01) adolescente, maior de 14 anos de idade atendida pelo PAEFI. Tamb?m foi realizada an?lise documental de documentos profissionais, elaborados a partir do atendimento e acompanhamento prestados a quatorze (14) adolescentes v?timas de explora??o sexual. A observa??o livre tamb?m comp?s os procedimentos e t?cnicas, fazendo-se presente durante a realiza??o de toda a pesquisa. Dentre os resultados, destaca-se que a prostitui??o foi a modalidade de explora??o sexual mais atendida pelo PAEFI; a totalidade das v?timas compreende o sexo feminino; as principais situa??es de vulnerabilidade social presentes no cotidiano das fam?lias referem-se ao analfabetismo e baixa escolaridade dos pais, desemprego e inser??o prec?ria no mercado de trabalho, baixa remunera??o, prec?rias condi??es de moradia, fragiliza??o e rompimento de v?nculos familiares, hist?rico de abuso sexual, drogadi??o, envolvimento de adolescentes com homens mais velhos em troca de dinheiro e acesso a bens e servi?os. Pode-se perceber tamb?m que o PAEFI carece de investimentos na infraestrutura material e humana. Dentre os desafios apresentados para a qualifica??o das pol?ticas sociais no que se refere ao enfrentamento da explora??o sexual de crian?as e adolescentes destaca-se a necessidade de capacita??o e qualifica??o dos profissionais do PAEFI, bem como daqueles que trabalham em diferentes servi?os e pol?ticas p?blicas que comp?em a rede de prote??o ?s crian?as e adolescentes; incorpora??o das diferentes modalidades de explora??o sexual (prostitui??o infantil, turismo sexual, pornografia infantil, tr?fico para fins de explora??o sexual) nos documentos e relat?rios utilizados pelos profissionais do PAEFI para caracterizar as demandas de atendimento no que se refere a esse tipo de viol?ncia sexual; a realiza??o de um trabalho interinstitucional e intersetorial que tenha como foco as situa??es sociais de vulnerabilidade e as necessidades sociais que d?o margem para a explora??o sexual de crian?as e adolescentes. Com base nos resultados e problematiza??es desenvolvidas, confirma-se a tese de que as situa??es de vulnerabilidade social vivenciadas pelas fam?lias contribuem para a produ??o e reprodu??o das rela??es de explora??o sexual de crian?as e adolescentes. Estas situa??es possuem diversas determina??es, destacando-se a desigualdade de g?nero e de classe, consumo como forma de inser??o social, as diferentes formas de manifesta??o da pobreza, a precariza??o no mundo do trabalho a desagrega??o familiar em face da reprodu??o das rela??es sociais e pol?ticas sociais que de forma insuficiente buscam dar respostas ?s demandas e necessidades sociais das fam?lias. Tais determina??es n?o se manifestam de forma isolada, pelo contr?rio, estabelecem m?tua rela??o entre si, ao passo que atingem de forma particular as fam?lias das adolescentes em situa??o de explora??o sexual. Em outras palavras, constituem-se como express?es do conflito entre capital e trabalho.

Previous issue date: 2015-12-18 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / This research paper discusses about the photographic production of the Photo Klos studio in Panambi (RS) in the 1930s and 1940s. Founded in 1913 in Panambi in the Northwest region of Rio Grande do Sul by immigrant Wilhelm Adam Klos, the studio remains as venture family until the present day, accounting a century of existence. The time frame established by the survey corresponds to the period when Frieda Doeth Klos took over the administrative activities and photographic studio. The research aimed to understand the moments that involved the negotiation for the production of family images consumption and circulation of photographs. Besides consulting the private studio collection - pictures and documents - interviews and reproduction of the images to used in the study produced by glass negatives were also made. Among the results of the research it is said that the photographs were used as a means of legitimizing the family outside the local society and the family and friends far away, seeing that the most of those portrayed in the being twentieth century, who besides be remembered, sought through images demonstrate their material progress. / O presente trabalho de pesquisa problematiza a produ??o fotogr?fica do est?dio Foto Klos em Panambi (RS) nas d?cadas de 1930 e 1940. Fundado em 1913 em Panambi na regi?o Noroeste do Rio Grande do Sul pelo imigrante Adam Wilhem Klos, o est?dio se mant?m como empreendimento familiar at? os dias atuais, contabilizando um s?culo de exist?ncia. O recorte temporal estabelecido pela pesquisa corresponde ao per?odo em que Frieda Doeth Klos assumiu as atividades administrativas e fotogr?ficas do est?dio. A pesquisa buscou entender os momentos que envolveram a negocia??o para a produ??o das imagens de fam?lia, o consumo e a circula??o das fotografias. Al?m da consulta ao acervo particular do est?dio - imagens e documentos -, tamb?m foram realizadas entrevistas e a reprodu??o das imagens utilizadas no trabalho a partir de negativos de vidro. Entre os resultados da pesquisa destaca-se que as fotografias foram utilizadas como forma de legitimar a fam?lia perante a sociedade local, familiares e amigos distantes, visto que a maioria dos retratados no in?cio do s?culo XX eram imigrantes ou descendentes, que al?m de serem lembrados, buscavam por meio das imagens demonstrar seu progresso material.

Previous issue date: 2016-07-18 / The objective of this study is to evaluate the implementation of a social development
program, o Servi??o de Prote????o e Atendimento Integral ??s Fam??lias (PAIF), that
happens in the Social Assistance Reference Centers (CRAS), unit considered the
gateway to the social policy assistance. The PAIF is responsible for performing
actions on prevention and social promotion, working in coordination with the main
cash transfer program in Brazil, the Bolsa Fam??lia Program (PBF). Therefore, this
study focuses on one of the social protection structures in Brazil designed to the
principles of the welfare state. Throughout this work, will be presented theoretical
discussions of the welfare state and the history of the implementation of social
programs in the Brazil after 1988, the democratic period. It will also be presented a
research of the implementation process of public policy, considering the studies
carried out on implementation evaluation of social programs and the possible
influences of the professionals in this activity. To get in the objective of analyze and
evaluate the implementation of the PAIF a mixed methods research was used in the
CRAS units in the Federal District that offered the program. It was applied a
questionnaire identifying the profile of Higher Education Professional and were
interviewed four professionals that works in high social vulnerability areas of the
Federal District. This research provided an assessment of the implementation of the
PAIF and offers reflections for program settings and the future implementation of new
programs. / O objetivo deste trabalho ?? avaliar a implanta????o de um programa de
desenvolvimento social, o Servi??o de Prote????o e Atendimento Integral ??s Fam??lias
(PAIF), ofertado nos Centros de Refer??ncias de Assist??ncia Social (CRAS), unidade
considerada porta de entrada para a pol??tica de Assist??ncia Social. O PAIF ??
respons??vel por executar a????es de preven????o e promo????o social, trabalhando de
forma articulada com o principal programa de transfer??ncia de renda do Brasil, o
Programa Bolsa Fam??lia (PBF). Portanto, este estudo foca em uma das estruturas de
Prote????o Social do Brasil concebida ?? luz dos princ??pios do Welfare State. Ao longo
do trabalho, ser??o apresentadas as principais discuss??es te??ricas sobre o Welfare
State, o hist??rico da implementa????o de programas sociais no per??odo democr??tico
brasileiro ap??s 1998. Ser?? apresentado tamb??m um levantamento sobre o processo
de implementa????o de pol??ticas p??blicas, considerando os estudos j?? realizados
sobre avalia????o de implementa????o de programas sociais e as poss??veis influ??ncias
dos profissionais nesta atividade. Para alcan??ar o objetivo de analisar e avaliar a
implementa????o do PAIF, realizou-se uma pesquisa de m??todos mistos nas unidades
de CRAS do Distrito Federal que executam o programa. Foi aplicado um
question??rio identificando o perfil dos profissionais de N??vel Superior das unidades e
foram entrevistados quatro profissionais de unidades localizadas em ??reas de
grande situa????o de vulnerabilidade social no Distrito Federal. Esta pesquisa
proporcionou uma avalia????o sobre a implementa????o do PAIF e contribuiu com
reflex??es para ajustes do programa e na futura implementa????o de novos programas.

Genèse du Système Hydrothermal à Fluorine-Barytine-Fer de Chaillac, (Indre, France)Sizaret, Stanislas 05 December 2002 (has links) (PDF)
Le système hydrothermal de Chaillac est situé à la limite du Massif Central et du bassin de Paris. Il se compose d'un gisement stratiforme de barytine (Les Redoutières et La Raillerie), connecté à un gisement filonien de fluorine (Le Rossignol).<br />Le filon du Rossignol recoupe le socle métamorphique hercynien. Ce filon est une structure ouverte remplie à la faveur de deux stades paragénétiques : le premier stade appelé Fv-v est constitué de fluorine verte et violette et de quartz montrant des fabriques sédimentaires intrafiloniennes. Ce stade s'est formé à 135°C à partir d'une solution de faible salinité. Les compositions isotopiques du Sr et Nd évoquent une source liée aux roches acides de la croûte supérieure. Le second stade (Fj-Ba) se compose de fluorine jaune, de sulfures et de barytine ; trois sous-stades ont été définis : (i) fluorine dominante, (ii) barytine dominante et enfin (iii) brèche à ciment de fluorine. Les sous stades (i) et (ii) sont présents en continu de la racine du système jusqu'aux filons horizontaux (plateures) du gisement stratiforme. L'ensemble du stade Fj-Ba s'est formé à partir de saumure (≈20% wt Eq. NaCl) à environ 100°C. Les signatures isotopiques du Sr et Nd évoquent des compositions de roches basiques d'origine profonde.<br />Le gisement stratiforme des Redoutières est encaissé dans des sables hettangiens (205 – 201 Ma) du bassin de Paris. A proximité du filon du Rossignol, le grès est cimenté par de la fluorine qui passe latéralement et verticalement à de la barytine puis à une association barytine-gœthite ; ces variations de la nature du ciment sont corrélées avec les sous-stades (i) et (ii). A l'aplomb du filon du Rossignol, des « filons » verticaux N-S, E-W et horizontaux forment un sinter très original à barytine et gœthite puissant de 5 à 8 m. Les structures de ce dernier démontrent une mise en place synchrone d'une tectonique d'ouverture E-W et N-S. L'âge hettangien de cette minéralisation est attesté par la présence de galets de barytine dans les grés hettangiens, les modifications de la nature du sédiment (gœthite détritique), les textures de type sinter et l'absence de minéralisation dans les calcaires sinémuriens. L'étude de l'anisotropie de susceptibilité magnétique (ASM) des formations filoniennes et stratiformes riches en gœthite, couplée à la géochimie des traces a permis de démontrer et de quantifier une phase de latéritisation tardive supperposée à l'hydrothermalisme à l'Eocène. Par ailleurs, l'étude des fabriques magnétiques permet de tracer les directions des paléoécoulements hydrothermaux.<br />L'ensemble des résultats permet de proposer un modèle génétique. Celui-ci suggère la venue d'un fluide hydrothermal profond à Ba, F, Fe qui entre en ébullition vers 1,6 km de profondeur. La phase vapeur se condense pour donner le fluide formant le stade Fv-v et la saumure résiduelle migre pour déposer tardivement de la fluorine, de la barytine par mélange avec des fluides continentaux de surface et des oxy-hydroxydes de fer.

Une détermination des caractéristiques mécaniques résiduelles de versants naturels : méthodes à l'équilibre limite et des éléments finisAl Hayari, Mohamed 26 April 1989 (has links) (PDF)
L'objectif principal de ce travail est de mettre à la disposition des géotechniciens une gamme de valeurs de caractéristiques mécaniques, en l'occurrence angle de frottement interne et cohésion, propre à des séries sédimentaires du Sud-Est de la France dont l'instabilité pose souvent des problèmes. Pour la prévision du comportement du terrain de talus ou de remblais, la pratique courante est d'introduire, dans les calculs, des paramètres tirés d'essais (au laboratoire ou en place), ce qui suppose une homogénéité satisfaisante des terrains concernés, Au contraire, pour les glissements de versants naturels, on n'est nullement assuré d'avoir affaire à des masses homogènes. et il faut bien admettre que les paramètres mécaniques intervenant tout au long de la surface cinématique sont variables. Dans ces conditions, plutôt que de recourir à des essais ponctuels, il semble plus logique d'en chercher une évaluation en faisant appel à l'analyse inverse, méthode globale qui lisse les irrégularités locales. Cette méthode a donc été appliquée, dans l'hypothèse de l'équilibre limite, à des glissements de dimensions diverses, survenus dans des conditions hydrogéologiques comparables. Parmi les quatre formations analysées - Houiller, Lias, Terres Noires, Argiles litées - ces dernières, vu leur homogénéité, ont même pu faire l'objet d'un traitement spécifique (mesures ponctuelles classiques et mise on oeuvre de la Méthode des Eléments Finis). Les valeurs paramétriques proposées semblent susceptibles de servir de référence au moins pour des calculs menés en phase d'études préliminaires.

Etude de la couverture sédimentaire de la bordure ouest du massif des Grandes Rousses ( Bourg d'oisans) - IsèreBornuat, Michel 01 November 1961 (has links) (PDF)
Au départ, notre étude ne devait porter que sur les formations sédimentaires, mais nous avons dû l'élargir à la tectonique des massifs cristallins qui commande en partie celle de la couverture . Celle-ci, d 'un point de vue géographique et structural, peut être subdivisée en deux parties : - le "synclinal liasique d ' Allemont " entre Belledonne et les Grandes Rousses ; - le placage sédimentaire d'Auris , conservé grâce à l'ensellement du substratum entre les Grandes Rousses et l ' extrémité NW du massif du Pelvoux . A l 'échelle des Alpes, l'ensemble est reconnu depuis longtemps conme faisant partie intégrale de la zone dauphinoise .
