OBJECTIVE: to review the evolution of acute respiratory distress syndrome (ARDS) definitions and present the current definition for the syndrome. DATA SOURCE: a literature review and selection of the most relevant articles on ARDS definitions was performed using the MEDLINE®/PubMed® Resource Guide database (last ten years), in addition to including the most important articles (classic articles) that described the disease evolution. DATA SYNTHESIS: the review included the following subjects: introduction; importance of definition; description of the first diagnostic criterion and subsequently used definitions, such as acute lung injury score; definition by the American-European Consensus Conference, and its limitations; description of the definition by Delphi, and its problems; accuracy of the aforementioned definitions; description of most recent definition (the Berlin definition), and its limitations; and practical importance of the new definition. CONCLUSIONS: ARDS is a serious disease that remains an ongoing diagnostic and therapeutic challenge. The evolution of definitions used to describe the disease shows that studies are needed to validate the current definition, especially in pediatrics, where the data are very scarce.

Effects of bentazon, metolachlor, trifluralin, imazethapyr, imazethapyr+lactofen, haloxyfop-methyl, glyphosate and chlorimuron-ethyl at rates of 2 and 10 times the equivalent commercial dose on soil microbial activity was evaluated in soil samples extracted from a field never treated before. Global soil microbe respiration, estimated by CO2 production at 2, 4, 8, 12, 16, 20, 24 and 28 days of soil incubation and enzymatic activities (dehydrogenase and fluorescein diacetate hydrolysis) at 8 and 28 days were used as bioindicators. Bentazon and mixture imazethapyr+lactofen at the highest rate and haloxyfop-methyl at both rates, inhibited soil respiration although with differences in timing and duration. None of the herbicides affected FDA hydrolysis. Dehydrogenase activity was inhibited at 8 days of incubation with bentazon and imazethapyr at high rates but it was stimulated by metolachlor and imazethapyr at low rate and glyphosate at the highest rate. Herbicide effects on soil microbial activity was detected with higher sensitivity by global soil microbe respiration and dehydrogenase activity than by FDA hydrolysis. Only dehydrogenase activity and soil respiration estimations at 8 days of soil incubation had significant correlation. Results indicated the need of multiple estimations when evaluating herbicides effects on soil microbiota

Os conceitos e aplicações da ergonomia estão em constante discussão no âmbito acadêmico, caracterizando um corpus de conhecimento de grande expressividade para a própria ciência ergonômica e demais áreas tecnológicas correlatas, a saber: engenharias, design, arquitetura, e outras. Entre as demandas para ampliar as análises em torno dessa disciplina apresenta-se sua evolução histórica, a qual está completa de controvérsias e discussões. De fato, há ainda uma grande dificuldade em relatar suas etapas históricas dentro do âmbito geográfico e a participação de seus precursores nessas fases. Assim, o propósito dessa coletânea foi o de reunir os estudos realizados pelos alunos da linha de pesquisa ergonomia, associados ao Laboratório de Ergonomia e Interfaces - LEI, no Programa de Pós-graduação em Design - PPGDesign, da Faculdade de Arquitetura, Artes e Comunicação da Universidade Estadual Paulista, e apresentar subsídios para ampliação da discussão e reflexão evolutiva da ergonomia. Os primeiros capítulos relatam os precursores da ergonomia, com destaque para Leonardo da Vinci e seus estudos na área da anatomia; Bélidor, Patissier e suas contribuições para a organização do trabalho; o Taylorismo e os aspectos da organização científica do trabalho, bem como a contribuição de Jules Amar nesse âmbito. Os demais capítulos abordam a origem e evolução da ergonomia na Europa, na Rússia (ex URSS), Estados Unidos da América, América Latina e Brasil, com ênfase a criação de laboratórios e associações não governamentais. De modo geral, os estudos ora apresentados preenchem lacunas ainda existentes dentro da ergonomia e procuram estabelecer um elo de ligação para a continuidade futura das pesquisas na área

This study aimed the geological characterization at scale 1:50.000 of an area belonging to the southern sector of the Brasilia Belt, located in the western portion of the Passos Nappe, near the town of Cássia, MG. In this region, outcrops rock types belonging to Araxá Group, composed of metasediments associated with metavolcanics which form a tectonometamorphic terrain of great importance for understanding the geological evolution of southeast and midwest regions of Brazil. With the development of work was possible to group the rocks in 10 lithostratigraphic units and had been identified 3 different zones of metamorphism generated during the peak metamorphism. The structural pattern of the area shows that the main foliation has average dip 30 ° NW and mineral lineation parallel to the stretching direction with 290 °. Still, we can conf irm that this inverse gradient metamorphic rocks of the Passos Nappe, described by several authors. Also, were seen lithotypes of economic interest, some already in exploitation, such as clay and sand, and other mineral commodities, which are occurring and can be used: quartz, quartzite, garnet, kyanite, rutile and zircon.

This study presents the trajectory of domestic federal public debt from Brazil in the years 2003 to 2010. Scales the amount spent on financial burden to pay the debt in relation to what was spent on items related to social development, health, education and welfare. The study concludes that Brazil despite an increase in social spending, with effective results, expenditures for the cost of domestic federal debt were much higher than social spending. The numbers were expressive in the maintenance of debt and very tiny in relation to social spending
