Microbialitos da formação Codó (Aptiano Superior) às margens do rio Tocantins em São Miguel do Tocantins (TO)

The southwestern region of the São Luís-Grajaú Basin has a rare outcrop of the Codó Formation (upper Aptian) with seven outstanding microbialite bioherms along the left margin of the Tocantins river, near Imperatriz (MA). Resting on sandstones of the Grajaú Formation, the Codó Formation presents: 1) a 20 cm thick basal calcilutite with gypsite pseudomorphs and some fossil tree stems; 2) metric dark shales with carbonate nodules and thin intercalated carbonate layers, enclosing some microbial laminites; 3) a 2 cm thick upper breccia composed of microbialite fragments and other carbonate clasts, with halite hoppers on the top; 4) the carbonate bioherms, which partially overlie the extensive shales and interrupt them laterally, as well as the breccia. The bioherms in the northern part of the outcrop are thicker (<2 m) and have interbedded dark shales, whereas the southern are thinner and continuous in the vertical direction. In general, they are composed of irregular gently to strongly wavy microbial laminites, sometimes with pseudocolumnar to conical lamination. All microbialites with highest synoptic relief (<20 cm) look like columnar stromatolites on weathered lateral expositions. In plan view, the horizontal sections of these microbialites are circular to slightly elliptic, sometimes forming very small channels (N60W) filled with fine breccia. The highest bed of the northern bioherm has mixed microbial laminites and columnar stromatolites, where intercolumnar spaces were filled with microbialite clasts, fish bones, plant fragments and very small probable crustacean coprolites. Several fractures and deformation in this upper bed indicate an initial brecciation process probably caused by subaerial exposure. In microscopic scale, the lamination is smooth, diffuse, defined by subtle granulation differences of very fine granular calcite crystals within micrite, but oxide levels, dissolution surfaces or thin precipitated calcite veneers...

Caracterização química e legalidade em bebidas não alcoólicas de maçã

Apple is a fruit that offers promising prospect for industrialization as it has favorable characteristics for this purpose and can obtain products with good acceptance. In Brazil, approximately 15% of the production is processed into juice, and a portion is exported. Among the fresh fruit and juice, apple adds US$ 30 million annually to the Brazilian foreign exchange earnings. The aim of this study was to characterize, using chemical analysis, concentrated juices, commercial apple juice, nectar, and soft drink. In addition, to compare them with their respective Quality and Identity Standards (PIQ) published by the Ministry of Agriculture, Livestock and Food Supply (MAPA) and Codex Alimentarius. Concentrated juices and commercial beverages were analyzed in triplicate for soluble solids content (Brix), pH, total acidity (AT), and ratio. In concentrated juices, the Total Sugar Reducer (ART) was also assessed. The results obtained in the laboratory were compared with the PIQ and Codex Alimentarius to verify compliance with applicable regulations. Seven concentrate juices, five juices, six nectars, and three apple-flavoured soft drinks were analyzed. The Brix of pulpy and clarified concentrated juices were, respectively, 71.16±1.29 and 40.40±0.57°Brix. In all concentrated juices, the Brix was in accordance with Codex Alimentarius. The Brix and AT in sweetened clarified juices were 11.50±0.14°Brix and 0.18±0.04g of malic acid/100g sample. In pulpy whole juices the values ​​were 11.20±0.70°Brix and 0.30±0.06g of malic acid/100g sample. The values of Brix and AT in apple-flavoured soft drinks were 11.03±0.93°Brix and 0.18±0.04g of malic acid/100ml sample. Commercial juices and soft drinks also presented °Brix and AT in accord with the PIQ established by MAPA. The apple nectars could not be compared with the standards because they are not published by MAPA or Codex Alimentarius. The definition of the PIQ is an important tool for quality control of beverages manufacture in Brazil. Therefore, it is recommended for the control agencies to define the parameters that are not established.

Aspectos tradutórios em Ma vie ne sait pas nager de Élaine Turgeon

The work Translational aspects in Ma vie ne sait pas nager by Élaine Turgeon approaches the entire translation process of this francophone children's work. The theme choice was due to the interest in deepening the translational knowledge, in addition to performing an analysis of the own translation work done. Thus, the theoretical aspects related to the translation are reported throughout the work, a succinct exhibition of the history of translation, a brief view of the children's editorial market (in the world and more specifically in Brazil), the book theme and author style, and finally, the drawbacks overcome during the realization of the work - based upon the theoretical body of work consulted - and the solution encountered for this. At the end of this same work, some considerations are drawn, as well as some reflections upon the translation realized (with the studied texts attached in the body of work); accompanied by some findings observed concerning the theory

Here is the Plan: So What is the Question?

In this action research study of my classroom of 5th grade mathematics students, I investigated their understanding of the mathematical operations by having them write problems to match given equations. I discovered that writing a story to match an equation does provide insight into a student’s understanding of mathematical concepts, however, reading comprehension is a factor in the understanding. Readers who struggle with comprehension do struggle with understanding and writing math story problems. The discussion that follows the writing of a math story problem and the solving of the written problems helps to strengthen the students’ mathematical abilities as well as their communication skills and confidence levels. Through my study, students learned that it was alright to make mistakes because the learning from those mistakes is what is important. As a result of this research, I plan to continue to have students write stories to match given equations as a source of information about student understanding. I will continue to give opportunities to revisit those written problems as a tool to increase students’ comprehension and communication skills, as well as their confidence.

Possible early foraminiferans in post-Sturtian (716-635 Ma) cap carbonates

Foraminifera are an ecologically important group of modern heterotrophic amoeboid eukaryotes whose naked and testate ancestors are thought to have evolved similar to 1 Ga ago. However, the single-chambered agglutinated tests of these protists appear in the fossil record only after ca. 580 Ma, coinciding with the appearance of macroscopic and mineralized animals. Here we report the discovery of small, slender tubular microfossils in the Sturtian (ca. 716-635 Ma) cap carbonate of the Rasthof Formation in Namibia. The tubes are 200-1300 mu m long and 20-70 mu m wide, and preserve apertures and variably wide lumens, folds, constrictions, and ridges. Their sometimes flexible walls are composed of carbonaceous material and detrital minerals. This combination of morphological and compositional characters is also present in some species of modern single-chambered agglutinated tubular foraminiferans, and is not found in other agglutinated eukaryotes. The preservation of possible early Foraminifera in the carbonate rocks deposited in the immediate aftermath of Sturtian low-latitude glaciation indicates that various morphologically modern protists thrived in microbially dominated ecosystems, and contributed to the cycling of carbon in Neoproterozoic oceans much before the rise of complex animals.

The 1420 Ma Indiavai Mafic Intrusion (SW Amazonian Craton): Paleomagnetic results and implications for the Columbia supercontinent

The configuration and the timing of assembly and break-up of Columbia are still matter of debate. In order to improve our knowledge about the Mesoproterozoic evolution of Columbia, a paleomagnetic study was carried out on the 1420 Ma Indiavai mafic intrusive rocks that crosscut the polycyclic Proterozoic basement of the SW Amazonian Craton, in southwestern Mato Grosso State (Brazil). Alternating field and thermal demagnetization revealed south/southwest ChRM directions with downward inclinations for sixteen analyzed sites. These directions are probably carried by SD/PSD magnetite with high coercivities and high unblocking temperatures as indicated by additional rock magnetic tests, including thermomagnetic data, hysteresis data and the progressive acquisition of isothermal remanent magnetization. Different stable magnetization components isolated in host rocks from the basement 10 km NW away to the Indiavai intrusion, further support the primary origin of the ChRM. A mean of the site mean directions was calculated at Dm = 209.8 degrees, Im = 50.7 degrees (alpha(95) = 8.0 degrees, K = 22.1), which yielded a paleomagnetic pole located at 249.7 degrees E, 57.0 degrees S (A(95) = 8.6 degrees). The similarity of this pole with the recently published 1420 Ma pole from the Nova Guarita dykes in northern Mato Grosso State suggests a similar tectonic framework for these two sites located 600 km apart, implying the bulk rigidity of the Rondonian-San Ignacio crust at that time. Furthermore these data provide new insights on the tectonic significance of the 1100-1000 Ma Nova Brasilandia belt-a major EW feature that cuts across the basement rocks of this province, which can now be interpreted as intracratonic, in contrast to previous interpretation. From a global perspective, a new Mesoproterozoic paleogeography of Columbia has been proposed based on comparison of these 1420 Ma poles and a 1780 Ma pole from Amazonia with other paleomagnetic poles of similar age from Baltica and Laurentia, a reconstruction in agreement with geological correlations.

Tectonic implications of the 1419 Ma Nova Guarita mafic intrusives paleomagnetic pole (Amazonian Craton) on the longevity of Nuna

The Nuna supercontinent was probably assembled in the Paleoproterozoic, but its paleogeography and the timing for its demise are stills matter of debate. A paleomagnetic and geochronological study carried out on the Mesoproterozoic Nova Guarita dyke swarm (northern Mato Grosso State, SW Amazonian Craton) provides additional constraints on the duration of this supercontinent. Paleomagnetic AF and thermal treatment revealed south/southwest (northeast) magnetic directions with downward (upward) inclinations for 19 analyzed sites. These directions are carried by PSD magnetite with high unblocking temperatures as indicated by additional magnetic tests, including thermomagnetic curves, hysteresis loops and the progressive acquisition of isothermal remanence in selected samples. A positive contact test with the host granite in one of the studied dykes further attests to the primary origin of the characteristic magnetic component. A mean site direction was calculated at D-m = 220.5 degrees, I-m = 45.9 degrees (alpha(95) = 6.5 degrees, K = 27.7), which yielded a paleomagnetic pole located at 245.9 degrees E, 47.9 degrees S (A(95) = 7.0 degrees). Ar-40/Ar-39 dating carried out on biotites from four analyzed dykes yielded well-defined plateau ages with a mean of 1418.5 +/- 3.5 Ma. The Nova Guarita pole precludes a long-lived Nuna configuration in which Laurentia, Baltica, North China, and Amazonia formed a long and continuous block as previously proposed for the Paleoproterozoic. It is nevertheless fully compatible with a SAMBA (Amazonia-Baltica) link at Mesoproterozoic times. (C) 2011 Elsevier B.V. All rights reserved.

Aplicação de regressão baseada no uso do solo para predizer a concentração de material particulado inalável no município de São Paulo, Brasil

O estudo teve por objetivo construir um modelo de regressão baseada no uso do solo para predizer a concentração material particulado inalável (MP10) no município de São Paulo, Brasil. O estudo se baseou na média de MP10 de 2007 de 9 estações de monitoramento. Obtiveram-se dados demográficos, viários e de uso do solo em círculos concêntricos de 250 a 1.000 m para compor o modelo. Calculou-se regressão linear simples para selecionar as variáveis mais robustas e sem colinearidade. Quatro variáveis entraram no modelo de regressão múltipla. Somente tráfego leve em círculos concêntricos <250 m permaneceu no modelo final, que explicou 63,8% da variância de MP10. Verificou-se que o método de regressão baseada no uso do solo é rápido, de fácil execução. Entretanto, este modelo se baseou em medições de MP10 de poucos locais.
