In order to achieve this goal, the study was based on memories of life stories of immigrants who lived in the neighborhoods of Coqueiral de Aracruz and Barra do Riacho, both located in the municipality of Aracruz, in north of the State of Esp?rito Santo (ES), Brazil, between the 1970s and 1980s. In the study period of time, those transformations were commonly attributed to industrial development and migrant influx. Therefore, it revealed the influence and predominance of these phenomena (industrialization and migrant movement) on the path of these psychosocial and urban transformations. For this purpose, the study addressed the creation of these neighborhoods, their history and, through comparative analysis, we presented aspects that consolidate the transformations identified from the 1970s to 2010. The research permeated qualitative aspects by allowing us to understand the reasons, interactions, actions and group relationships. The methodology employed for gathering and analyzing data is grounded on Social Psychology, supporting the Theory of Migrations and Study Field of Social Memory. / O presente estudo identificou transforma??es psicossociais e urbanas em Aracruz examinando-as ? luz da Psicologia Social. Para o alcance desse objetivo tomou-se por base as mem?rias contidas nas hist?rias de vida dos migrantes residentes nos bairros Coqueiral de Aracruz e Barra do Riacho, ambos situados em Aracruz, munic?pio do norte do Estado do Esp?rito Santo/ES, entre as d?cadas 1970 e 1980. Comumente, no per?odo temporal pesquisado, atribu?a-se tais transforma??es ao desenvolvimento industrial e movimento migrat?rio. Desvelou-se, portanto, a influ?ncia e preponder?ncia destes fen?menos (industrializa??o e movimento migrat?rio), no percurso destas transforma??es psicossociais e urbanas. Para tanto, discorreu-se sobre a funda??o os bairros, sua hist?ria e, por meio de an?lise comparativa, foram apresentados aspectos que consolidam as transforma??es identificadas a partir da d?cada de 1970 at? o ano de 2010. A pesquisa permeou metodologicamente aspectos qualitativos por propiciar discernimento que se referem aos motivos, intera??es, a??es e rela??es grupais. A metodologia aplicada no levantamento e an?lise de dados firmou-se na Psicologia Social, sustentando-se na Teoria das Migra??es e Campo de Estudo da Mem?ria Social.

A NiTi wire with 2.5 mm in diameter, received in the work hardened state, was submitted to annealing heat treatments at 450 ?C and 500 ?C in order to verify the calorimetric and microstructural changes. The microstructure in the work hardened condition and after the annealing heat treatments was analyzed, which showed a coarsening of the martensite plates for higher temperatures and longer heat treatment times. The determination of the transition temperatures (As, Af, Ms, Mf) and the change in the transformation temperatures between the as received worked hardened and annealed material, were determined. Microhardness measurements did not reveal any significant influence of the annealing or subzero heat treatments on the mechanical behavior of the alloy.

(RN), that is, a black catholic fellowship on the sert?o potiguar. The devotion to Nossa Senhora do Ros?rio, in colonial Brazil, organizes itself through black catholic men as fellowships. They blossomed in Brazil until the abolition, getting support from the Catholic church, from owners of slaves and from the population in general − unlike others afro-Brazilian religious expression. Today, these fellowships remain active, against the sentimental pessimism of the folklore studies, and they also have a highlight position in the calendar of many cities in Brazil, and in particular in Serid?. The research s foothold is the apparent valorization of the fellowship by the local elite, attitude that hides asymmetric relationships between the group of negros do Ros?rio and the local authorities, having as its consequence that the members occupy a subaltern position inside their own fellowship. This subalternity take place, mainly, in the public area, where the negros do Ros?rio cannot represent themselves neither political nor discursively. To discuss this idea, it s done a brief historical of these catholic institutions as well as a description of the relationship between the negros do Ros?rio and the elites of the city. Then, the phenomenon is analyzed as folklore and/or religion , under the perspective of many agents that participate in this process. In other moment, it is going to be presented how the group formulates their own representation of the history, of the devotional forms and of their own political-religious experiences. In this sense, an ethnography of the subalternity is understood as an analysis of the process that leads the negros do Ros?rio to become a subaltern group. It s also outlined the perception that the group has of its own position, through an ethnography essay of the subaltern subject. The research, focused in the group of Ros?rio, was done between August 2010 and January 2012 and includes other agents (like treasurers, priests and intellectuals). Besides that, as a methodological complement, there are documental research, photography, as well as shoots of the party days and public presentation / O objeto deste trabalho ? a irmandade de S?o Sebasti?o e Nossa Senhora do Ros?rio da cidade de Jardim do Serid? (RN), irmandade negra no sert?o potiguar. A devo??o a Nossa Senhora do Ros?rio, no Brasil col?nia, organizou-se institucionalmente atrav?s de irmandades cat?licas de homens pretos. Estas floresceram no Brasil at? a aboli??o e receberam o apoio da Igreja, dos senhores e da popula??o em geral, ao contr?rio de grande parte das express?es religiosas afro-brasileiras. Hoje, contrariando o pessimismo sentimental dos folcloristas, elas ainda continuam ativas e ocupam um lugar de destaque no calend?rio festivo de v?rias cidades no Brasil, e em particular no Serid?. O ponto de partida da pesquisa ? a aparente valoriza??o da irmandade por parte da elite local, postura que esconde rela??es assim?tricas entre os negros do Ros?rio e as autoridades locais, tendo como consequ?ncia o fato de os integrantes da irmandade ocuparem uma posi??o subalterna dentro dela pr?pria. A referida subalternidade se d?, principalmente, na esfera p?blica, pois os negros do Ros?rio n?o se representam politicamente e nem discursivamente. Para discutir essa ideia, faz-se um breve hist?rico dessas institui??es cat?licas, bem como uma descri??o das rela??es entre os negros do Ros?rio e as elites da cidade. Em seguida, o fen?meno ? analisado enquanto folclore e/ou religi?o e sob a perspectiva dos v?rios agentes que interv?m no processo. Em outro momento, ser? apresentada a maneira como o grupo formula suas pr?prias representa??es da hist?ria, das formas devocionais e de suas viv?ncias pol?ticoreligiosas. Nesse sentido, ? tra?ada uma etnografia da subalternidade pensada como a an?lise do processo que leva os negros do Ros?rio a se tornarem um grupo subalterno. ? delineada, tamb?m, a percep??o que este grupo tem da sua posi??o, a partir de um ensaio de etnografia do sujeito subalterno. A pesquisa de campo, centrada no grupo do Ros?rio, foi realizada entre agosto de 2010 e janeiro de 2012 e incluiu outros agentes (como tesoureiros, padres e intelectuais). Al?m disso, como complementa??o metodol?gica, foram utilizadas pesquisa documental, fotografias, bem como filmagens das festas e apresenta??es p?blicas

Arises from the fact that the dance has specific characteristics that can not be neglected by the historical account. In this sense, it was initiated by the raising of a theoretical framework that speaks to the indicated issues and unfolds through a field study, which included collecting testimonies from people who participated in the show, documentary research, gathering material traces and finally consists a practical part by transposing elaborated historical knowledge into the body through a creative process, resulting on this moment, in the construction of a duo dance / Esta pesquisa investigou o espet?culo de dan?a Caldo da Cana que estreou em Jo?o Pessoa-PB, em setembro de 1984.

Through an autobiographic narrative, in a qualitative approaching, the intent is to stand up aspects about the individual history and collective memories, starting in a simple question: what did they remember? A question that turns into many others, as how the remember and under which circumstances. So, the lived and remembered moments are the subject of this paper, as these testimonials shows and reveals the citizens typical aspects, intending to telling (again) the city s history by the memories of this people. By oral statements and the analysis that followed, subjective aspects that made a social memory, highlight in violent episodes, that, now remembered, occurred in the historical sediment, which connects several social times, establishing a narrative standard. In Jandu?s, this standard is about the memory that sticks out their individual ways, and the collective life, in the past, standing out the fair and the events that occurred on it, as the most remembered place, where the memories go stronger. When they narrate are incorporated others facts, the story is reinvented, connecting the past to the future. The paper also revels builders subjects aspects of a social memory, as historical sediment that joins the social times. At the present moment, the fair, to them, is a place that doesn t exist anymore; for the city, is a place of enlargement of women s presence at the trending spaces, which means a place of social transformation. That being said, the fair, in both times, present and past, turns into a analysis object, with important elements to reference narrative s time and place. And how the narrative update the past recorded in the old citizen s memory. What was intended to do was articulate the memory and the history form temporal and special etching that define the place and the narrative context: the lived and the remembered at the group s day by day. In that way, were identify the collective memory s common elements, enunciating the memory and the narratives that update that history, influencing and being influenced, forming in memories in a collective phenomenon fueling the local imaginary / Evidencia a mem?ria de um grupo de idosos, como experi?ncia substantiva na constru??o de uma mem?ria social da cidade de Jandu?s, Rio Grande do Norte, locus da pesquisa. Por meio de uma narrativa autobiogr?fica, numa abordagem qualitativa, busca-se evidenciar aspectos da trajet?ria individual e da mem?ria coletiva do grupo, partindo de uma pergunta comum: o que eles lembravam?

Thereon, two currents are perceived. The first was marked by a nostalgic bias about the past, being formulated by intellectuals from the region that was turning as Northeast. This group of intellectuals emphasized values and traditions of the agrarian aristocracy of the region that was losing visibility in the political and economic Brazil scene. Already the other current has a more modern and industrial feature, was formed by intellectuals from the Southeast that in detriment of the first, was rising. This group, on the other hand, was intended to give a new face to Brazil and break with the "roots" of our delay that in their view were linked to our agrarian past. This resulted in different perceptions and interpretations of our historical past, and the construction of different profiles to the Brazilian. Accordingly, our work seeks to understand how was produced the writing that silenced the mixed ancestry of Auta de Souza (1876-1901) considering the position that she should occupy in the intellectuals projects who were in charge of forming a memory for our state. Auta as a relevant historical character in this project of potiguares intellectuals, she was raised to the condition of a model woman and elected in the pantheon of the most beloved poets of Rio Grande do Norte, however, to occupy such prestigious position she had her racial ancestry concealed in the writings that these same intellectuals had written about her, what is still spreaded in memory and rituals places of religious and civic features / Na primeira metade do s?culo XX diferentes grupos de intelectuais estiveram engajados na busca de um ideal de brasilidade. Nisso, duas correntes s?o percebidas. A primeira foi marcada por um vi?s saudosista em rela??o ao passado, sendo formulada pelos intelectuais da regi?o que ent?o gestava-se como Nordeste. Esse grupo de intelectuais ressaltava valores e tradi??es da aristocracia agr?ria da regi?o que perdia visibilidade no cen?rio pol?tico e econ?mico do Brasil. J? a outra corrente, de car?ter mais moderno e industrial, foi formada pelos intelectuais da regi?o Sudeste que em detrimento da primeira, estava em ascens?o. Este grupo por sua vez, objetivava dar um novo rosto ao Brasil bem como romper com as ra?zes do nosso atraso que na vis?o deles estavam ligadas ao nosso passado agr?rio. Isso resultou em diferentes percep??es e interpreta??es sobre nosso passado hist?rico, e na constru??o de diferentes perfis para o brasileiro. Nesse sentido, nosso trabalho busca entender como se produziu uma escrita que silenciava a ancestralidade mesti?a de Auta de Souza (1876-1901) haja vista a posi??o que ela deveria ocupar dentro do projeto dos intelectuais que ficaram a cargo da forma??o de uma mem?ria para o nosso estado. Auta enquanto personagem hist?rica relevante nesse projeto dos intelectuais potiguares foi al?ada ? condi??o de mulher modelo e elegida no pante?o das poetas mais amadas do Rio Grande do Norte, todavia, para que pudesse ocupar tal posi??o teve sua ancestralidade racial escamoteada nos escritos que esses mesmos intelectuais fizeram sobre ela, o que, por sua vez, se estendeu em lugares de mem?ria e em rituais de car?ter religioso e c?vico

Readings were made seeeking to emphasize the processivity of the play that navigates between permanence and change. The study starts with a social context of the community, in dialogue with the life history of the owner of the epiphany, Raimundo Mil?: strong figure who, along with his family networks, as well as networks of patronage and friendship, struggles for the resistence of the play. The description of the ceremony of Kings, with its constituent parts, punctuates the remarkable character of Cip? community epiphany. This detailed understanding of the play favors the understanding of some of the social vines that serve as the basis for the warp of this cultural practice: modernization vine, where we explore the general motivation of Cip? community epiphany transformations - modernity; family and community exchange vine, which describes the scheme that holds the permanence of the play; masculinity vine, explains the strong gender system that crosses Cip? community epiphany; reinvented tradition vine, where we locate the uniqueness of Cip? community epiphany tradition and its dialogues with modern dynamism; conflict between generation vine, depicts the differences between generations and how they contribute to the dialogue between the traditional and the new; theatrical spectacle vine, describes the play as a performative activity.

A primeira, numa escala menor, ? um conjunto de c?lulas sincronizadas, que funcionam de forma transit?ria como um sistema fechado de processamento; a ?ltima, numa escala maior, corresponde ? ativa??o sequencial de assembleias de c?lulas neuronais capazes de representar percep??es e comportamentos. Atualmente, o registro de grandes popula??es neuronais permite a detec??o simult?nea de diversas assembleias neuronais. No ?mbito da teoria de Hebb, o pr?ximo passo l?gico ? a an?lise das sequ?ncias de fase. Neste trabalho investigamos seq??ncias de fase como padr?es de ativa??es consecutivas de assembleias, analisando a rela??o entre comportamento animal e atributos de grafos de assembleias. Foram estudados trens de disparo neuronal registrados no hipocampo e neoc?rtex de 5 ratos adultos, antes, durante e depois da explora??o de novos objetos (per?odos experimentais). Para definir um grafo de assembleia, cada assembleia correspondeu a um n?, e cada aresta correspondeu ? sequ?ncia temporal de ativa??o de n?s consecutivos. A soma da ativa??o de todas as assembleias foi proporcional ? taxa de disparo, mas a atividade de assembleias individuais n?o. O repert?rio de assembleias permaneceu est?vel ao longo dos per?odos experimentais, indicando que a experi?ncia com novos objetos n?o criou novas assembleias no rato adulto. Os atributos de grafos das assembleia, por outro lado, variaram significativamente entre os estados comportamentais e per?odos experimentais e foram distintos o suficiente para permitir a classifica??o autom?tica dos per?odos experimentais (classificador Naive Bayes; AUROCsm?ximas variaram entre 0,55 a 0,99) e estados comportamentais (vig?lia, sono de ondas lentas e sono de movimento r?pido dos olhos; AUROCs m?ximas variaram entre 0,64 e 0,98). Nossos achados refor?am a teoria Hebbiana de que as assembleias neuronais correspondem a estruturas primitivas de representa??o, quase inalteradas na maturidade, enquanto as seq??ncias de fase s?o inst?veis entre os estados comportamentais e mudam ap?s novas experi?ncias. Os resultados s?o compat?veis com um papel das sequ?ncias de fase no comportamento e cogni??o. / Hebb proposed that synapses between neurons that fire synchronously are strengthened, forming cell assemblies and phase sequences. The former, on a shorter scale, are ensembles of synchronized cells that function transiently as a closed processing system; the latter, on a larger scale, correspond to the sequential activation of cell assemblies able to represent percepts and behaviors. Nowadays, the recording of large neuronal populations allows for the detection of multiple cell assemblies. Within Hebb?s theory, the next logical step is the analysis of phase sequences. Here we detected phase sequences as consecutive assembly activation patterns, and then analyzed their graph attributes in relation to behavior. We investigated action potentials recorded from the adult rat hippocampus and neocortex before, during and after novel object exploration (experimental periods). Within assembly graphs, each assembly corresponded to a node, and each edge corresponded to the temporal sequence of consecutive node activations. The sum of all assembly activations was proportional to firing rates, but the activity of individual assemblies was not. Assembly repertoire was stable across experimental periods, suggesting that novel experience does not create new assemblies in the adult rat. Assembly graph attributes, on the other hand, varied significantly across behavioral states and experimental periods, and were separable enough to correctly classify experimental periods (Na?ve Bayes classifier; maximum AUROCs ranging from 0.55 to 0.99) and behavioral states (waking, slow wave sleep, and rapid eye movement sleep; maximum AUROCs ranging from 0.64 to 0.98). Our findings agree with Hebb?s view that neuronal assemblies correspond to primitive building blocks of representation, nearly unchanged in 10 the adult, while phase sequences are labile across behavioral states and change after novel experience. The results are compatible with a role for phase sequences in behavior and cognition

A tese foi dividida em quatro experimentos. No primeiro, foi realizada a estimativa e descri??o das caracter?sticas histol?gicas e ultraestruturas dos fol?culos pr? antrais (FOPA) de cutias (Dasyprocta leporina), nos quais foram estimados 4419.8 ? 532.26 e 5397.52 ? 574.91 fol?culos para os ov?rios direito e esquerdo, respectivamente, sendo a maioria (86,63%) pertencente a categoria de fol?culos primordiais (P<0,05). A maior parte da popula??o consiste de fol?culos morfologicamente normais (70,78%), apresentando n?cleo oocit?rio grande e central, com citoplasma uniforme. Na avalia??o ultraestrutural verificou-se a presen?a de um grande n?mero de mitoc?ndrias arredondadas e gotas de lip?dios. No segundo experimento, foi realizada a estimativa e a descri??o das caracter?sticas dos FOPA de pre?s (Galea spixii), bem como avalia??o do efeito da vitrifica??o em superf?cie s?lida (VSS) sobre a morfologia de FOPA in situ. O total de 416,0 ? 342,8 FOPA foi estimado por par de ov?rios e a presen?a de uma grande quantidade de fol?culos prim?rios foi evidenciada (P<0,05). A maior parte dos FOPA apresentou-se morfologicamente normal (94,6%), possuindo n?cleo oocit?rio contendo gr?nulos condensados de heterocromatina. Mitoc?ndrias com formato arredondado ou alongado representaram as organelas mais abundantes. Quanto a VSS, o protocolo utilizando o dimetilsulf?xido (DMSO) 3M possibilitou a preserva??o de 69,5% de FOPA morfologicamente normais, sendo evidenciado atrav?s da an?lise por microscopia de luz e eletr?nica de transmiss?o. No terceiro experimento, foi realizada a avalia??o do efeito da VSS sobre a morfologia e viabilidade de FOPA in situ de catetos (Pecari tajacu). N?o foram observadas diferen?as entre os tratamentos, onde o uso dos crioprotetores DMSO, etilenoglicol (EG) e dimetilformamida (DMF), independente da concentra??o utilizada (3 ou 6 M) promoveu a preserva??o da morfologia de mais de 70% dos FOPA. Quanto a viabilidade, os crioprotetores DMSO e EG, demonstraram melhor manuten??o da mesma. O quarto experimento teve por objetivo avaliar o efeito do ? MEM+ ou TCM199 associados ou n?o a 50 ng de FSHr sobre a morfologia, ativa??o e crescimento de FOPA de catetos, cultivados in vitro (CIV) durante 1 ou 7 dias e o efeito sobre a matriz extracelular (MEC). Ap?s 7 dias de CIV apenas o TCM199/FSH manteve a propor??o de FOPA intactos similar ao dia 1 (63,2%), contudo nenhuma diferen?a foi observada entre os tratamentos (P>0,05). Adicionalmente, um aumento na propor??o de FOPA em desenvolvimento foi verificada (P>0.05). Atrav?s da an?lise com Ag-NOR, observou-se que apenas o tratamento com TCM199/FSH manteve a propor??o de prolifera??o celular similar ao dia 1 (P>0.05). A colora??o com picrosirius red revelou que a MEC permaneceu intacta em todos os tratamentos (P>0.05). Assim, como conclus?o geral, o uso da MOIFOPA nas referidas esp?cies permitiu o conhecimento de aspectos relacionados a sua morfofisiologia reprodutiva, possibilitando tanto a conserva??o do material gen?tico destas esp?cies, com a possibilidade de forma??o de bancos de germoplasma, como a elucida??o de mecanismos relacionados a sobreviv?ncia e desenvolvimento dos FOPA in vitro. / The objective of the present thesis was to use the manipulation of oocytes enclosed in preantral follicles (MOEPF) as a tool for the female gametes rescue and optimization, from wild species of Caatinga biome. The thesis was divided into 4 experiments. At first experiment, it was performed the estimative and description of the agouti (Dasyprocta leporina) preantral follicles (PF) histologic and ultrastructural features, in which it was estimated 4419.8 ? 532.26 and 5397.52 ? 574.91 follicles for the right and left ovary, respectively, and the majority (86,63%) belonged to the primordial follicles category (P<0.05). Most of the population consists of morphologically normal follicles (70.78%), presenting a large and central nuclei and uniform cytoplasm. At ultrastructural evaluation it was verified the presence of a great number of round mitochondrias associated to lipid droplets. In the second experiment, it was performed the estimative and description of yellow-toothed cavies (Galea spixii) PF characteristics, also, the evaluation of the effect of solid surface vitrification (SSV) on the in situ PF morphology. The total of 416.0 ? 342.8 PF was estimated for the ovary pair and the presence of a large quantity of primary follicles (P<0.05) was evidenced. Most of the PF was morphologically normal (94.6%), in which the oocyte nuclei presented condensed granules of heterochromatin. Round or elongated shaped mitochondria constituted the most abundant organelles. In regard of the SSV, the protocol using the dimethylsulfoxide (DMSO) 3M possibility the preservation of 69.5% of morphologically normal PF, which was evidenced by the light and transmission electronic microscopy. At third experiment, the evaluation of the SSV procedure on the morphology and viability in situ PF form collared peccaries (Pecari tajacu) was performed. No differences were observed among treatments, in which the use of DMSO, ethylene glycol (EG) and dimethylformamide (DMF) as cryoprotectants, regardless its concentration, promoted the morphology preservation of much than 70% of PF. Concerning the PF viability, the DMSO and EG promoted the best preservation. The fourth experiment aimed to evaluate the effect of ? MEM+ or TCM199 associated or not to 50 ng of FSHr on the morphology, activation and growth of collared peccaries PF, in vitro cultured (IVC) during 1 or 7 days and the effect on the extracellular matrix (ECM). After 7 days of IVC only the use of TCM199/FSH maintained the proportion of intact PF, similar to day 1(63.2%), however, no differences were observed among treatments (P>0.05). Also, an improvement of the proportion of intact growing PF was verified (P>0.05). By the Ag-NOR analysis it was observed that only the treatment using TCM199/FSH promoted the maintenance of cell proliferation similar to day 1 (P>0.05). The picrosirius red stain revealed that ECM remained intact in all treatments (P>0.05). Thus, as the general conclusion, the use of MOEPF in the refereed species allowed the knowledge of aspects related to its reproductive morphology and physiology, enabling the germplasm conservation, with the possibility of germplasm bank formation, as the elucidation of mechanisms related to the PF survive and in vitro development.
