ABSTRACT: The Rio Pardo salient, the large antitaxial curve described by the Araçuaí fold-and-thrust belt along the southeastern edge of the São Francisco craton, is one of the most prominent and one of the least studied features of the Brasiliano Araçuaí-West Congo orogenic system (AWCO). In addition to the Archean/Paleoproterozoic basement, the salient is comprised of metasedimentary rocks mainly from the Neoproterozoic Macaúbas Group and the Salinas Formation. Its western limb occupies a portion of the Espinhaço ridge, where the NS-trending structures of the Araçuaí belt progressively curve NE and E, thereby defining the hinge zone along the Serra Geral on the Minas-Bahia boundary. The eastern limb is NW-trending and marked by a major shear zone. In models postulated to generate the AWCO through the closure of the Neoproterozoic Macaúbas basin, this large curve plays a critical kinematic role. Yet, in spite of this, its development is still not fully understood. How did this curve originate? Which factors controlled its generation? Our field study performed in the northern Araçuaí orogen characterized the kinematic picture of the salient, and led to a model that addresses these questions. The results we obtained indicate that the Rio Pardo salient developed in response to four deformation phases. The contractional D1 and D2 phases are coaxial and responsible for a craton-directed tectonic transport along the salient’s outer arc, which is coupled with an overall southward motion of the inner arc, thereby giving rise to a rather complex kinematic picture. Furthermore, structures of the D1/D2 phases define a zigzag pattern with alternating NE- and NW-trending segments along the salient’s leading edge. Along the NE-trending segments, the metasedimentary rocks are thrust northwestwards on top of the craton basement, while along the NW-trending segments, the supracrustal rocks are displaced along dextral to reverse-dextral transpressional shear zones located on the basement/cover contact. Structures of the D3 phase, which are well developed in the hinge zone, record a final WSW-ENE contraction, which was responsible for rotation of the preexistent fabric elements around NNW-trending axes and the enhancement of the salient curvature. The D4 phase is extensional and is recorded by two large-scale structures, the Chapada Acauã and Tingui normal shear zones, as well as by the normal-sinistral reactivation of the Itapebi strike-slip shear zone that marks the salient eastern limb. We interpret the initiation of the Rio Pardo salient during the collisional 565-575 Ma D1/D2 phases essentially as a primary arc that is mainly controlled by the geometry of the Macaúbas precursor basin. The thickened internal portion of the Rio Pardo salient was affected by extensional tectonism at c. 530 Ma, and is recorded by the D4 deformation phase, which is currently ascribed to the extensional collapse of the Araçuaí-West Congo orogen.

Após 10 anos da promulgação da Lei nº 10.436/2002, constata-se que a presença de alunos surdos nas salas de aula comuns já é uma realidade. Com a regulamentação do Decreto Federal nº 5.626/2005, notam-se avanços no que concerne ao acesso e à inclusão dos alunos surdos nos ambientes educacionais, consolidando lutas históricas da comunidade surda. Nesse sentido, a busca por novas estratégias de ensino e de avaliação da aprendizagem faz-se necessária. No entanto, percebe-se que muitos tradutores/intérpretes de língua de sinais (TILS) possuem dificuldades para interpretar os conceitos científicos, muitas vezes distantes da sua formação. O objetivo deste trabalho é fornecer aos professores e TILS, das séries iniciais do Ensino Fundamental, subsídios para o ensino dos conceitos relacionados à astronomia. Para isso, foi realizada uma pesquisa de levantamento dos sinais relacionados à astronomia, indicados pelos Parâmetros Curriculares Nacionais (PCNs), presentes em dois principais dicionários de Libras em circulação no país e em um dicionário especializado em Astronomia. Por meio desse levantamento, foram analisados 49 conceitos e suas definições, fazendo uma releitura e indicando uma definição mais adequada para os TILS e professores. Constatouse que as definições de alguns sinais presentes nos dicionários possuem distorções, redundâncias e conteúdos que demandam uma formação mais específica para sua abordagem. A releitura permitiu a construção de uma redação mais simples e ofereceu a possibilidade da sugestão de conceitos ainda não constituídos na Libras.

Ten years after the enactment of the 10.436/2002 law, it is clear that the presence of deaf students in regular classrooms has become a reality. After the regulation of the Federal decree nº 5.626/2005, advances can be noted regarding access and inclusion of deaf students in educational environments, consolidating historical efforts by the deaf community. As a result, there is a demand for pursuing new strategies for teaching and for learning assessment. However, we have noticed that many sign language translators/interpreters (TILS) have problems interpreting scientific concepts, with which they are often unfamiliar. The aim of this study is to provide teachers and TILS working in first year elementary level classes with assistance for teaching concepts related to astronomy. To this end, we conducted a survey of signs related to astronomy, according to vocabulary indicated in the Brazilian National Curriculum Parameters (PCN). The signs were available in the two main Libras dictionaries used in the country, as well as in a dictionary specialized in Astronomy. This survey enabled us to analyze 49 concepts and their definitions, by means of which we conducted a rereading of same and indicated more adequate definitions for TILS and teachers. We found that definitions of some signs presented in the dictionaries were distorted and redundant, requiring greater specificity in the explanations. This revision enabled us to produce simpler entries and allowed us to suggest concepts that have not as yet been coined in Libras.

OBJETIVO: Analisar o perfil epidemiológico de crianças e adolescentes na faixa etária de 0 a 19 anos atendidos no pronto atendimento do Hospital Escola Municipal, de maneira a monitorar a rede de saúde de São Carlos, no estado de São Paulo. MÉTODOS: Estudo descritivo e transversal com coleta dos dados de prontuários, entre agosto de 2008 e setembro de 2009 (14 meses), sendo uma amostra aleatória, ao acaso, de 15 dias dos atendimentos em 50% das consultas mensais, somando-se 13.339 prontuários de um total de 26.678 atendimentos. Foi construído um banco de dados no programa Epi-Info para análise descritiva. RESULTADOS: Do total, 48,3% dos pacientes eram do sexo feminino, 55% com idades entre zero e quatro anos e 95% oriundos de demanda espontânea. Isso corresponde a um esboço de 41% da população entre 0 e 19 anos de idade que teve somente este tipo de atendimento. Houve predomínio das doenças do aparelho respiratório (48,5%), nos meses de outono e inverno. As regiões que mais utilizaram o pronto atendimento compreenderam bairros das regiões norte, nordeste e noroeste de São Carlos, as quais possuem ampla densidade populacional. CONCLUSÕES: Os resultados apontaram a difícil realidade, com alta demanda espontânea, de crianças de zero a quatro anos no pronto atendimento pediátrico, sem acolhimento prévio a esses pacientes. A situação da rede de saúde aponta para a necessidade de medidas urgentes que fortaleçam a assistência das unidades básicas de saúde e de saúde da família.

OBJECTIVE: To analyze the epidemiological profile of children and adolescents aged between 0 to 19 years, assisted by the emergency department of a City School Hospital in order to monitor the health care system of São Carlos, São Paulo, Southeast Brazil. METHODS: This is a descriptive and cross-sectional study that collected data from medical records, from August 2008 to September 2009 (14 months). The random sample was taken from 15 days of each month, 50% of the total of 26,678 patients seen during that period of time, accounting for 13,339 medical records. The Epi-Info software was used to build the database; results were evaluated by descriptive statistical analysis. RESULTS: Among the analyzed medical reports, 48.3% were female patients, 55% of the patients were aged between 0 and 4 years. Most of the children (95%) came by spontaneous demand. During that period, 41% of the population aged 0 to 19 years-old sought for only this type of health care. The most prevalent diseases were respiratory diseases, which showed 48.5% incidence during fall and winter. Most patients came from the north, northeast, and northwest regions of São Carlos, which have high-population density. CONCLUSIONS: The results showed a sad reality, with high spontaneous demand of children aged from zero to four years-old for pediatric emergency care. Most patients had not received prior care from other doctors. The health network situation indicates the need for urgent measures to strengthen the primary care assistance for basic health care centers and family physicians.

OBJETIVO: Analizar el perfil epidemiológico de niños y adolescentes en la franja de edad de 0 a 19 años, atendidos en el Servicio de Urgencias (SU) del Hospital Escuela Municipal, de modo a monitorear la red de salud de esa ciudad. MÉTODO: Estudio descriptivo y transversal con recolección de datos de prontuarios, entre agosto de 2008 y septiembre de 2009 (14 meses), con muestra aleatoria, al azar, de 15 candidatos de los servicios en 50% de las consultas mensuales, sumando 13.339 prontuarios de un total de 26.678 atenciones. Se construyó una base de datos en el EpiInfo para análisis descriptivo. RESULTADOS: Del total, el 48,3% de los pacientes eran del sexo femenino, el 51,7% del sexo masculino, el 55% con edad entre 0-4 años y el 95% originarios de demanda espontánea, correspondiendo a un bosquejo del 41% de la población entre 0 a 19 años de edad que tuvo solamente ese tipo de atención. En 48,5%, hubo predominio de las enfermedades del sistema respiratorio los meses de otoño e invierno. Las regiones que más utilizaron el SU comprendieron barrios de la región norte, nordeste y noroeste de la ciudad, que poseen gran densidad de población. CONCLUSIONES: Los resultados señalaron la dura realidad, con alta demanda espontánea, en niños de 0 a 4 años de edad en el servicio de urgencias pediátrico, sin acogida previa a esos pacientes. La situación de la red de salud apunta a la necesidad de medidas urgentes para el fortalecimiento de la asistencia en unidades básicas de salud y de salud de la familia.

Foi investigada a associação entre os polimorfismos de base única (SNPs) T2411C e T3266G da leptina e as características de carcaça em suínos F2 procedentes do cruzamento de machos da raça Piau com matrizes comercias de composição genética Landrace, Large White e Pietrain. As análises de associação foram feitas usando um modelo estatístico que incluía genótipo, sexo e lote como efeitos fixos, e pai e erro como efeitos aleatórios. O SNP T2411C esteve associado ao peso da copa sem pele e sem gordura (BSW), à espessura de gordura subcutânea na altura da última costela a 6,5 cm da linha média (P2), ao peso da paleta sem pele e sem gordura e ao peso do filezinho (SLW). O SNP T3266G foi associado a idade de abate, peso do bacon, BSW, espessura da gordura subcutânea entre a última e a penúltima vértebra lombar, na linha média, espessura da gordura subcutânea na altura da última costela na linha média, P2 e peso da costela. Os genótipos combinados para ambos os SNP estiveram associados a P2, peso total da copa, rendimento de carcaça e peso do filezinho. Os SNPs analisados têm potencial para ser explorados como marcadores para composição de carcaça em suínos.

It was investigated the association between leptin gene single nucleotide polymorphisms (SNPs) T2411C and T3266G with carcass traits in F2 pigs obtained by crossing native Brazilian Piau with commercial sows composed of Landrace, Large White and Pietrain breeds. Association analyses were performed using a statistical model that included genotype, sex, and batch as fixed effects, sire and error as random effects. The T2411C SNP was associated with skinless and fatless boston shoulder weight (BSW), backfat thickness at last rib, 6.5 cm from the midline (P2), skinless and fatless picnic shoulder weight, and sirloin weight (SLW). The T3266G mutation was associated with slaughter age, bacon weight, BSW, midline backfat thickness between last and last but one lumbar vertebra, midline backfat thickness at last rib, P2 and rib weight. Phenotypic associations were also performed by combining genotypes for both SNPs. Associations with P2, carcass yield, total boston shoulder weight, and SLW were observed. The results obtained demonstrate that the SNPs analyzed have potential to be explored as markers for carcass composition in pigs.

Investigou-se neste trabalho a associação entre o marcador microssatélite IGF-I em uma população F2 (N=459) gerada pelo acasalamento entre suínos nativos brasileiros e fêmeas comerciais com características de desempenho, cortes de carcaça e qualidade da carne. A análise de associação foi feita por meio de um modelo que incluiu genótipo, sexo e grupo como efeitos fixos e pais como efeito aleatório. Os genótipos do IGF-I apresentaram associação significativa com nove características quantitativas, resultados que corroboram análises prévias de QTL obtidas para essa região cromossômica em suínos. Efeitos aditivos de dominância, assim como a interação genótipo × sexo, foram estimados e estão descritos neste trabalho. De acordo com os resultados obtidos, este marcador será útil nas análises de QTL na população analisada.

This study investigated the association between IGF-I microsatellite marker in an F2 population (N=459) generated by mating of native boars to Brazilian commercial sows with performance, carcass cut, and meat quality traits. Association analyses were carried out using a statistical model that included genotype, sex, and group as fixed effects and sire as random effect. The IGF-I genotypes were significantly associated with different quantitative traits and these results corroborate with previous QTL analyses obtained for this chromosome region in swine. Additive and dominance effects, as well as a genotype-sex interaction, were estimated and discussed in the text. According to the results obtained, this marker is suitable for QTL search in the genotyped population.

The PSS genotypes of 596 F2 pigs produced by initial mating of Brazilian native boars commercial sows and were characterized by PCR-RFLP and their carcass and performance traits were evaluated. Among the 596 animals analyzed, 493 (82.72%) were characterized as NN and 103 (17.28%) as Nn. With respect to carcass traits, Nn animals presented higher (p < 0.05) right half carcass weight, left half carcass weight, loin depth and loin eye area, and lower shoulder backfat thickness, backfat thickness between last and next to last but one lumbar vertebrae and backfat thickness after last rib at 6.5 cm from the midline compared to NN animals. Nn animals also showed (p < 0.05) higher values for most of the cut yields, indicating higher cutting yields for animals carrying the n allele and lower values for bacon depth, confirming lower fat deposition in carcass. In addition, Nn animals presented (p < 0.05) lower values for the performance trait weight at 105 days of age. These results indicate that animals carrying the PSS gene generate leaner carcasses, higher cut yields, and that the effects of the gene can be observed even in divergent crosses.
