In this report, we present a boy with lower lip pits, distinct craniofacial dysmorphism with cleft lip and palate, central nervous system malformation, and severe mental retardation. Similar but less pronounced facial findings were present in his mentally normal mother and maternal grandfather, both presenting with lower lip pits. Cleft lip was present in patient's father. Analysis of the VWS1 and VWS2 regions were performed to elucidate the molecular basis of the phenotype of the propositus. Screening or mutations at the IRF6 gene detected a pathogenic mutation (c.960G > C) in the propositus and in his mother; and a single nucleotide polymorphism (c.175-5C > G) in the propositus and in his father. Clinical and genetic aspects of this case are discussed.

This research comprises a study on the values and ideals attributed to Dix-sept Rosado, by the Coleção Mossoroense journal. Local researchers demonstrate how the Coleção Mossoroense constructs an image of Mossoró, forming in the members of the city an identity with the place, a social cohesion or creating one forms to see and to say about the Mossoró city. The Coleção Mossoroense, through Vingt-un Rosado together with its family, established a form of seeing and identifying of the Mossoró s population with the city, just because it associated and it was, at the same time, a movement at the same time social (civic parties for example), political (the domination of the Rosado s family) and cultural (the books and theatrical parties about the city). The conjunction of the Coleção Mossoroense as and with a social movement, cultural and political was capable to establish a social identity, a subjective constituent . With this background, it was possible to make a study of the image attributed to Dix-sept Rosado, by the Coleção Mossoroense, through an analysis of the inherent discourse in the works by Bakhtin (1989) and Bourdieu (2000), of and on Dix-sept Rosado in the Coleção Mossoroense based on. The image of Dix-sept Rosado was constructed by the Coleção Mossoroense after its death, and the responsible for this was Vingt-un Rosado, which was the chief-editor of the Coleção Mossoroense up to 2006, year of its death. The Coleção Mossoroense built an image of Dix-sept Rosado as an enterprising man, progressive and innovator, of great capacity of leadership and oratory (a conductor of the crowds ), popular and charismatic, an honest and dynamic politician. This image made by the Coleção Mossoroense, although when enhancing in surplus the qualities of Dix-sept Rosado have as objective to transmit an image of a heroic personage, it has some relation with the reality. Dix-sept Rosado was a man identified with its locality. This can resemble a regional nationalism. The attitudes of Dix-sept Rosado must be understood inside of a broader social context, of a time marked by the populist politics. Qualities also appreciated and developed inside of a specific historical context and determined both national and locally. The Coleção Mossoroense enhances the qualities of Dix-sept Rosado so that the current politicians of the Rosado s family can establish a link of continuity in its contemporary political practice

In this work a detailed thermodynamic analysis for an extraction-condensation steam turbine capable to drive a 40 MVA electricity generator in a sugar-alcohol factory was carried out. The use of this turbine in the cogeneration system showed that its efficiency contributed to increase the power generation, although the condensation reduces the overall efficiency of the plant. Sensibility analyses were performed to evaluate the behavior of the overall energy efficiency of a plant with the extraction-condensation turbine in function of the boiler efficiency, the specific consumption of steam in the processes and the condensation rate in the turbine. It was observed that the plant efficiency is very sensible to the condensation rate variation and it increases when there is an increase in the demand of steam for processes.

This work measured the effect of milling parameters on the surface integrity of low-carbon alloy steel. The Variance Analysis showed that only depth of cut did not influence on the workpiece roughness and the Pearson's Coefficient indicated that cutting speed was more influent than tool feed. All cutting parameters introduced tensile residual stress in workpiece surface. The chip formation mechanism depended specially on cutting speed and influenced on the roughness and residual stress of workpiece.

The objective of this study was to analyze variability, linear and spatial correlations of forage dry mass yield (FDM) and dry matter percentage (DM%) of Brachiaria decumbens with the bulk density (BD), gravimetric (GM) and volumetric (VM) moisture, mechanical resistance to penetration (RP) and organic matter content (OM), at depths 1 (0-0.10 m) and 2 (0.10-0.20 m), in a Red Latosol (Oxisol), in order to select an indicator of soil physical quality and identify possible causes of pasture degradation. The geostatistical grid was installed to collect soil and plant data, with 121 sampling points, over an area of 2.56 ha. The linear correlation between FDM × DM% and FDM × BD2 was low, but highly significant. Spatial correlations varied inversely and positively, respectively. Except for DM% and BD, at both depths, the other attributes showed average to high variability, indicating a heterogeneous environment. Thus, geostatistics emerges as an important tool in understanding the interactions in pasture ecosystems, in order to minimize possible causes of degradation and indicate better alternatives for soil-plant-animal management. The decrease in FDM and increased BD1 are indicators of physical degradation (compaction) of Red Latosol (Oxisol), particularly in the places with the highest concentration of animals and excessive trampling, in Cerrado conditions, in the municipality of Selvíria, Mato Grosso do Sul State, Brazil.

Uma alternativa para suprir o aporte anual de palha exigido para manutenção do sistema plantio direto (SPD), nas regiões tropicais, é o cultivo de milho consorciado com urochloas. Com o objetivo de identificar o melhor sistema de cultivo de duas espécies forrageiras (Urochloa brizantha e Urochloa ruzizienses) em consórcio com o milho (Zea mays L.) em sistema plantio direto, foi realizada a presente pesquisa. O milho foi semeado em consórcio com as forrageiras em cinco sistemas de cultivo. Foi utilizado o delineamento em blocos ao acaso, em esquema fatorial (2x4+1), com quatro repetições. Foram avaliadas: massa seca de palha do milho, massa seca da palha de urochloa, massa seca total de palha, população de plantas de milho, massa de 1000 grãos e produtividade de grãos. Os resultados demonstraram que o consórcio de milho com urochloa não apresentou efeito negativo na produtividade do milho e incrementou o aporte de matéria seca no sistema de produção sob plantio direto. A escolha de determinado sistema de cultivo depende do gerenciamento e da disponibilidade de máquinas, visto que todos os sistemas apresentaram comportamento positivo em relação à produtividade de grãos e à produção de palhada.

Avaliando o comportamento do feijoeiro inoculado com cinco estirpes de Rhizobium tropici e a adubação mineral com nitrogênio, sobre alguns fatores relacionados à sua produtividade, utilizou-se um delineamento experimental de blocos ao acaso, com oito tratamentos constituídos pela inoculação do feijoeiro cultivar IAC Carioca com cinco estirpes de Rhizobium tropici (CIAT 899 - estirpe referência; F35; F54; F81 e CM255), dois controles sem inoculação sendo um adubado com N na semeadura e em cobertura e outro sem adubação e um cultivar não nodulante (NORH 54) adubado; com seis repetições. Avaliaram-se: número de nódulos por planta; massa de material seco da parte aérea; teor de N nas folhas; número de vagens por planta; número de grãos por planta; número de grãos por vagem; peso de 100 grãos e produtividade de grãos. A inoculação de estirpes eficientes de Rhizobium em cultivar nodulante de feijoeiro, ou o cultivo deste em solos com população nativa eficiente, pode possibilitar a não utilização de nitrogênio em cobertura na cultura do feijoeiro, sem afetar a produtividade.

Em fruticultura, existe hoje uma grande tendência de aumento da densidade de cultivo, procurando com isso uma maior produção por área. Pretendeu-se, neste trabalho, desenvolvido em Ilha Solteira-SP, estimar e analisar comparativamente o custo de produção e a lucratividade de bananeira-'Nanicão Jangada', sob duas densidades de cultivo: 1666 plantas (3,0mx2,0m) e 2500 plantas (2,0mx2,0m). Para o cálculo do custo, utilizou-se a estrutura do custo total de produção (CTP). Considerando os dois ciclos produtivos do bananal, o espaçamento de plantio mais adensado (com maior número de plantas por área) apresentou resultados econômicos mais satisfatórios que os obtidos para o cultivo menos adensado. A cultivar 'Nanicão Jangada' é uma alternativa de cultivo viável para a região de Ilha Solteira-SP.
