Soybean rust caused by Phakopsora pachyrhizi Sydow & P. Sydow is one of the major diseases of the soybean crop. The aim of this study was to evaluate the effects of sowing dates, plant populations and reduced doses of fungicides on soybean rust severity and its effects on plant development and yield, cultivar MG/BR46 (Conquista). Field experiments were conducted in the 2009/2010 and 2010/2011 harvests, under natural rust infestation of soybean rust. As from the appearance of the first disease symptoms, also began the fungicide spraying and the disease severity assessments. To understand the nature and extent of the effects of different treatments, a multivariate analysis of factors was applied. For the majority of the agronomic characters and factors, one-third to two-thirds of their variability can be explained by changes in plant populations or by differences in the fungicide treatments, and the remainder, was explained by sowing date variations. The fungicide treatments and sowing dates are determinants in disease severity and its interference on crop productivity. The characters of plant growth are more dependent on plant population variations. Treatments with azoxystrobina + ciproconazol promoted smaller disease severities, reflecting in productivity increase. The plant populations can be reduced up to 160.000 plants ha(-1) without losses in the disease control and the soybean yield. In general, the earliest sowings provided increase in the plant development, although the rust control was less efficient.

The lithium industry has changed and the producers of lithium carbonate form South America play a dominant role in the world. This paper discusses the South American geological resources, production and producers of lithium considering the potential growth in lithium consumption for electric vehicle batteries. Taking into account the manufacturing companies and their external connections, their participation in corporate groups and the international market for the stocks of metal, in addition to facts and updates that affect this market and its key growth trends. This inventory of the most important reserves takes into account the geological context of the formation of these deposits, including a description of the types of deposits exploited in the world today. Besides the general description was made a brief description of the South American resources, more exploited by the media (Salar de Atacama, Salar de Hombre Muerto, Salar de Uyuni) and Pegmatites of Província Pegmatítica Oriental do Brasil and Província Seridó-Borborema).

The N6 Plateau presents an iron-ore occurence in Carajás Mineral Province, standing near to actually operating deposits. Geological mapping in 1:10,000 scale and integration of geochemical, geophysical, petrography and drilling turns possible interpretation of his geological evolution. The mapped area has lithotypes from Archean Grão Pará Group, comprising very lowgrade metamorphic basic rocks and iron formation and an Proterozoic sedimentary association of conglomeratic sandstones called as Caninana Unity. The structural geology in given by a regional scale homoclinal, where the Grão Pará Group strata dips towards SW, as a part of the Northern Limb of the Carajás Fold. Subsequent deformation associated to the installation of the Carajás Shear Zone presents as E-W fold axis. Geochemical evidence permits to consider de Parauapebas Formation as the rocks which has been hydrothermally-altered to outsourcing fluids responsible to deposition of iron formations in the oceanic system, including different signatures which can be interpreted as possible sub-embayments in the Carajás Basin. The iron ore in the area occurs in subsurface as very fine friable hematite generated by supergenous enrichment of the iron formation. The conceived geologic model differs from the current academic proposal on the fact that hydrothermal alteration has been involved on the jaspelite enrichment. Metamorphism on the Parauapebas Formation presents paragenesis considered as ocean-floor metamorphism which precedes de deformation insofar as the rocks show no tectonic fabric referring to shallow crust evolution. Geophysical methods such as magnetometry and gravimetry presents excellent results for structural interpretation in uneven exposed terrain

The Mesozoic acid volcanism of the Paraná-Etendeka Province can be considered as one of the biggest events of its kind in the Earth's surface, and its study have attracted special interest in characterizing the end of magmatism that preceded the rupture process and the formation of continental Africa and South America Although significant, the acid volcanism featuring Members Chapecó Palmas and Serra Geral Formation represents only 2.5% of the total generated by the magmatic rocks and perhaps therefore the existing literature on these rocks is well less significant than that on the basalts. However, there are still aspects still unclear about the origin and evolution of these rocks in relation to the associated basalts. Thus, two profiles were selected, called RA and TA, which be a systematic collection of samples from the base where the Botucatu Formation sandstones occur at the top, where they observe Palmas acid rock type. These samples should be analyzed for major, minor and trace elements and treated in specific diagrams to define the vertical variation lithochemistry and their possible relationships with the associated basalts

This paper presents and discusses initiatives taken in a public university in the state of São Paulo in order to collect and organize a corpus composed of argumentative texts to be part of Br-ICLE – a subcorpus of ICLE1 – which is composed of texts produced by Brazilian students enrolled in the courses of Arts and Languages and Translation. The discussion is based on a three-year project in which we could observe underuse and overuse features in the texts produced by Brazilian undergraduate students.

We present a systematic investigation of the nature and strength of the hydrogen bonding in HX···HX and CH3X…HX (X = Br, Cl and F) dimers using ab initio MP2/aug-cc-pVTZ calculations in the framework of the quantum theory of atoms in molecules (QTAIM) and electron localisation functions (ELFs) methods. The electron density of the complexes has been characterised, and the hydrogen bonding energy, as well as the QTAIM and ELF parameters, is consistent, providing deep insight into the origin of the hydrogen bonding in these complexes. It was found that in both linear and angular HX…HX and CH3X…HX dimers, F atoms form stronger HB than Br and Cl, but they need short (∼2 Å) X…HX contacts.

The purpose of this study is to know the route of Special Education in different contexts, the city of Maringa/Brazil and Guadalajara/Spain and analyze the bases underlying the organization, structure and operation of this mode of education having as starting point the process inclusive school. This investigation is based on the theoretical and methodological principles of the historical-cultural notion by Vygotsky. He argues that the existence of fundamental principles underlying the development of children with disabilities. If, on the one hand, the disability imposes limitations on the individual, hindering its development, on the other, just by causing difficulties, enables the movement to compensate, increasing the development of other capabilities. The deficit itself is less. Therefore, it is a field research carried out by means of observations, literature search and document analysis in early childhood education institutions visited in the cities mentioned above. The results showed that there are peculiarities of its path, organization and functioning of Special Education in each of the contexts analyzed. Referentemente the inclusive education movement, it is clear that Spain is a precursor of this process therefore has the right conditions in different ways to conduct the service children with special needs, and on the other hand, schools have the resources and specialized materials they need. While in Brazil the operationalization of these measures occurs more slowly. Thus, we can say that this process of inclusive education does not happen in a linear fashion within mainstream schools and so little action in the different forms of special education in two contexts analyzed.
