Ver, lembrar e narrar: a conformação das memórias sobre a ditadura militar na recepção assistida do audiovisual

Subjective and socially constructed instance, the memory is not a natural phenomenon, but an area of contention between various social organizations for control and legitimation of a past. With the development of writing and the advent of new technical devices, it creates new ways to store and transport information. The memory is no longer restricted to the limits of the here and now of the subject and undergoes transformations. In this scenario, the media start to play an important role in publicizing and construction of embodiments of memory. This study aims to analyze the conformation of the memory of political groups during the process of receiving audiovisual fiction. For this purpose, a corpus of four chapters of the soap opera Love and Revolution was used as a cognitive device for remembering. The television series, broadcast by SBT between April 2011 and January 2012, went back to the beginning and development of the military dictatorship in Brazil, in the cities of Rio de Janeiro and São Paulo. Three militants of various affiliations Communists who acted against the regime in Rio Grande do Norte and neighboring states, were participants in this study. Using the method of oral history, the research was divided into two stages: in-depth interviews, which dealt with the history of life of employees with the militancy in the Communist parties and other social movements, and the assistance of a drive dramatic soap opera Love and Revolution. Comparing these two phases of the study, we analyze the flow of mediations that crossed memories of militancy and media framework; shifts the narrative of remembrance during reception, and the opposition between memory and represented the experiences of the receivers

O ensino da língua portuguesa na televisão: uma análise através do programa afinando a língua

The present dissertation aims to an approach of the teaching of Portuguese language on television, trying to find how possible is the contribution of this communication media in the sense to give a higher classroom dynamism and to excite the students for that subject. The TV show Afinando a Língua (roughly, putting the language in tune ), a Canal Futura feature, have as one of these main purpose be shown on the classrooms as a tool that could enlarge the possibilities of a subject often took as particularly difficult. Blocked by the traditional grammatical teaching, the Portuguese lessons have been for years pictured as hermetic and far from the Brazilian speakers reality. So, people create myths around the language that earns adjectives as complicate and inaccessible and that Brazilians can t speak the Portuguese really good, because it only happens in Portugal, the original country of the language. These myths start exactly because the teaching orientation take their basis only on the standard language, in fact just one of the language variations by the way, anywhere in the world dictated by ancestral rules, once produced in Portugal. The regular school don t accept the Portuguese variation as a natural fact for a huge country as Brazil, with almost 190 million people, regarding it as a wrong way of talking. The repression that follows the students from the early school days make them repel the language supposedly learned at school. In fact, they normally face it as something unfamiliar, different from the language that they have use to learn at home, from the family and neighbors Instead of giving new possibilities for the language learning, the television, a powerful audiovisual device, only reinforces the idea that everyone, in any life situation, should talk the standard Portuguese, turning its back to the learning acquired much earlier that any person reach the school. This conservative attitude brings almost no changes, between the shows that try to teach the idiom and the traditional Portuguese lessons, wasting valuable tools that could lead to the possibility to open the classroom to the outside world, and to the wider knowledge of the differences from each Brazilian region culture, a positive attitude that could much enlarge the cultural and linguistic students universe

O vídeo didático Conhecendo o Solo e a contribuição desse recurso audiovisual no processo de aprendizagem no ensino fundamental

O uso de recursos audiovisuais no ensino de solos, como estímulo para os alunos, pode auxiliar na construção de um conhecimento crítico e reflexivo. Este trabalho objetivou analisar a contribuição do vídeo Conhecendo o Solo no ensino e na aprendizagem dessa temática no nível fundamental. Com o intuito de estimular os alunos a perceber a importância dos solos nos ambientes, esse vídeo foi aplicado como conteúdo de ensino. em seguida, foi aplicado um questionário, em que os alunos descreveram as principais ideias transmitidas por esse, especificando os pontos positivos e negativos do recurso utilizado. A análise do questionário revelou que o uso do vídeo foi um facilitador da aprendizagem. Porém, as respostas dos estudantes indicaram que alguns aspectos necessitam de adequações, como o dinamismo, a interatividade, a quantidade de informações e a narração. Mesmo assim, o recurso foi classificado pela maioria dos alunos como adequado, e o repertório de conteúdos apresentou similaridade com o exposto no vídeo, caracterizando-o como um recurso de influência positiva no processo de ensino e aprendizagem.

Paracoccidioides brasiliensis antigen batches from the same isolate show immunological and biochemical differences

We investigated the occurrence of antigenic and biochemical variability among Paracoccidioides brasiliensis antigen batches prepared according to the same protocol. Initially (experiment 1), we analyzed two antigen lots of two human isolates (Bt1 and Bt2), cultured in two media (PYG: bactopeptone, yeast extract, glucose; MMM: McVeigh and Morton medium) in SDS-PAGE and in two immunological tests (immunodiffusion-ID and footpad swelling test-FPT). Afterwards (experiment 2), we compared the antigenic profile of three antigen hatches from three human isolates (Bt1, Bt2 and Bt3) by two-dimensional immunoelectrophoresis (2 D-IEP) against a reference system for P. brasiliensis antigens. In experiment 1, there were important intra- and inter-strain antigenic differences between batches of the fungal isolates cultured on both media. The block titration of the antigen batches for the immunological tests revealed correlation between protein concentration and biological activity in ID and no correlation in FPT. In experiment 2, the reference system for P brasiliensis showed 26 antigen peaks. There were important differences between batches prepared from the same isolate and between batches from different isolates. Our data suggested the occurrence of instability in the synthesis of antigenic components by a same P. brasiliensis isolate, under controlled incubation conditions.

Mouse extensor digitorum longus and soleus show distinctive ultrastructural changes induced by veratrine

We investigated whether veratrine (5 μl, 10 ng/kg) injected into the mouse extensor digitorum longus (EDL) (fast-twitch) and soleus (SOL) (slow-twitch) muscles provokes distinctive ultrastructural disturbances 15, 30 and 60 min later. The mitochondria in SOL were affected earlier (within 15 min) than in EDL. Swelling of the sarcoplasmic reticulum terminal cisternae was more marked in EDL than in SOL and caused distortion of sarcomeres so that fragmentation of myofilaments was more pronounced in EDL. Hypercontracted sarcomeres were seen mainly in SOL and veratrine caused infoldings of the sarcolemma only in this muscle. In both muscles, the T-tubules remained unaffected and by 60 min after veratrine most of the above alterations had reverted to normal. Pretreatment with tetrodotoxin prevented the alterations induced by veratrine. This suggests that most of the alterations resulted from the enhanced influx of Na+ into muscle fibers. These results emphasize the importance of considering the type of muscle when studying the action of myotoxic agents.

Nodule growth and nitrogen fixation of Calopogonium mucunoides L. show low sensitivity to nitrate

It is well established that nitrate is a potent inhibitor of nodulation and nitrogen fixation in legumes. The objective of this study was to demonstrate the relative insensitivity of these processes to nitrate with Calopogonium mucunoides, a tropical South American perennial legume, native to the cerrado (savannah) region. It was found that nodule number was reduced by about half in the presence of high levels of nitrate (15 mM) but nodule growth (total nodule mass per plant) and nitrogen fixation (acetylene reduction activity and xylem sap ureide levels) were not affected. Other sources of N (ammonium and urea) were also without effect at these concentrations. At even higher concentrations (30 mM), nitrate did promote significant inhibition (ca. 50%) of acetylene reduction activity, but no significant reduction in xylem sap ureides was found. The extraordinary insensitivity of nodulation and N2 fixation of C. mucunoides to nitrate suggests that this species should be useful in studies aimed at elucidating the mechanisms of nitrate inhibition of these processes. © 2010 Springer Science+Business Media B.V.

From widespread to microendemic: Molecular and acoustic analyses show that Ischnocnema guentheri (Amphibia: Brachycephalidae) is endemic to Rio de Janeiro, Brazil

Many species of tropical amphibians are restricted to very small ranges, and this microendemism coupled with ongoing habitat loss and susceptibility to emerging pathogens imperils the long-term persistence of these species. Incomplete taxonomic and distributional knowledge may obscure conservation assessment, particularly in putatively widespread species that are typically considered to be of Least Concern in Red List assessments, but that in fact may constitute complexes of partly microendemic species. Such is the case in the Steindachner's Robber Frog, Ischnocnema guentheri which, together with the recently recognized Ischnocnema henselii, is thought to occupy most of the Brazilian Atlantic Forest. To test whether these taxa may constitute a species complex of range-restricted and thus potentially threatened species, we analyzed 160 samples of I. guentheri and/or I. henselii for two molecular markers, 16S rRNA (16S) and recombination activation gene 1 (RAG1). To verify the monophyly of the complex, closely related species were also included in the 16S analysis. Congruent evidence from the molecular data and from analyses of advertisement calls support the existence of six distinct species within the complex: I. guentheri and I. henselii as well as four candidate new species. The lineages are distributed as a mosaic in the Atlantic Forest and are sympatric at some localities without indication of admixture. Their phylogeographical pattern partially agrees with paleo-models for the Atlantic Forest, but also suggests the existence of micro-refugia in less stable areas. I. guentheri, previously considered to be widespread, was found only in its type locality, a reserve within the urban area of Rio de Janeiro city. Although none of the species studied appears highly threatened with extinction, we recommend their IUCN threat status to be re-evaluated carefully for the next comprehensive update of the Red List of Brazil's amphibians. © 2013 Springer Science+Business Media Dordrecht.
