ASIAN SOYBEAN RUST INTEGRATED MANAGEMENT POTENTIAL: DISEASE SEVERITY, PLANT DEVELOPMENT AND YIELD COMPONENTS, CULTIVAR MG/BR-46 (CONQUISTA)

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 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.

Quantum chemical topological analysis of hydrogen bonding in HX…HX and CH3X…HX dimers (X = Br, Cl, F)

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.

Análise e reflexão sobre a educação especial inclusiva em Maringá/BR e em Guadalajara /ES

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.

Synthesis and characterization of [Ru(eta(6)-C10H14)(dppf)X][PF6] (X = Cl, Br, I, SnF3) compounds: The X-ray structure of [Ru(eta(6)-C10H14)(dppf)Cl][SnCl3]center dot 0.45CH(2)Cl(2)

The arene-ruthenium complex [Ru(eta(6)-C10H14)(dppf)Cl]PF6 (1) was used as a precursor for the syntheses of the [Ru(eta(6)-C10H14)(dppf)Br]PF6 (2), [Ru(eta(6)-C10H14)(dppf)I]PF6 (3). [Ru(eta(6)-C10H14)(dppf)SnF3]PF6 (4) and [Ru(eta(6)-C10H14)(dppf)Cl][SnCl3]center dot 0.45CH(2)Cl(2) (5) complexes by its reactions with KBr, Kl, SnF2 and SnCl2. respectively. All of the compounds were characterized by NMR, IR, Fe-57 and Sn-119-Mossbauer spectroscopy, and cyclic voltammetry. The single-crystal X-ray structure analysis of the [Ru(eta(6)-C10H14)(dppf)Cl] [SnCl3]center dot 0.45CH(2)Cl(2) complex revealed the expected piano-stool geometry. Cyclic voltammograms of the complexes showed only one quasi-reversible electrochemical process, involving the oxidation of Fe(II) and Ru(II) at the same potential, which was confirmed by exhaustive electrolysis experiments. Fe-57-Mossbauer parameters obtained for the complexes (1-5) were fitted with one doublet corresponding to a site of one iron(II). The Sn-119-Mossbauer parameters of the complex (4) indicate that tin is tetra covalent. (c) 2012 Elsevier Ltd. All rights reserved.

Pavimentando Roraima: a BR-174 como exemplo das lógicas neoliberais de transnacionalização do território na Amazônia Ocidental

Este artigo discute a pavimentação da BR-174 na metade da década de 1990 e as suas consequências socioespaciais no estado de Roraima. O caso é apresentado como um exemplo da transformação das intervenções territoriais na Amazônia no contexto da neoliberalização do Estado e da produção de um espaço econômico transnacional. Os investimentos federais para o desenvolvimento rodoviário e infraestruturas auxiliares trouxeram conectividade sem precedentes para o estado de Roraima, além de gerar crescimento econômico. Todavia, o artigo argumenta que, além dos novos discursos de desenvolvimento regional sustentável, as lógicas dominantes dos projetos, tais como o melhoramento da BR-174, são as de um neoliberalismo em expansão transnacional, no qual o Estado empreendedor torna-se um parceiro para o estabelecimento de mercados externos mais do que o principal agente da integração do território nacional. Assim, no desenho da BR-174, Roraima aparece, principalmente, como um espaço estratégico de conexão transfronteiriça que liga a Amazônia brasileira aos portos do Caribe. Entretanto, passada mais de uma década desde a conclusão do projeto, a concentração territorial tem se aprofundado ao passo que emergem novas desigualdades socioespaciais intimamente atreladas às funções e fluxos que a integração rodoviária criou.

Binary liquid-liquid equilibria for systems of mono or disubstituted haloakanes (Cl,Br) and pyiridinium based ionic liquids. Advances in the experimentation and interpretation of results

[EN]This work presents the measurements made to define the temperature−composition curves for a set of binary systems composed of several pyridinium-based ionic liquids (ILs) [bpy][BF4] and [bYmpy][BF4] (Y = 2,3,4) with mono- and dihaloalkanes (Cl and Br) in the temperature interval [280−473] K and at atmospheric pressure. With the exception of the short chain dichloroalkanes (1,1- and 1,2-), all the compounds present some degree of immiscibility with the ionic liquids selected.

Molecular phylogeography of the European coastal plants Crithmum maritimum L., Halimione portulacoides (L.) Aellen, Salsola kali L. and Calystegia soldanella (L.) R. Br.

The intraspecific phylogeography of four European coastal plants, Crithmum maritimum, Halimione portulacoides, Salsola kali and Calystegia soldanella, was inferred from AFLP and ITS data. Only in C. maritimum, H. portulacoides and S. kali, a spatial genetic structure was revealed. The phylogeographic similarities and dissimilarities of these species include: (1) All three have distinct Black/Aegean and Adriatic Sea clusters. (2) Salsola kali and H. portulacoides show a distinct Atlantic/North Sea/Baltic Sea cluster, while Atlantic and eastern Spanish material of C. maritimum clustered together. (3) In the west Mediterranean, only S. kali forms a single cluster, while both H. portulacoides and C. maritimum display a phylogeographic break in the vicinity of the southern French coast. For S. kali, AFLP and ITS data concur in identifying separate Atlantic, east and west Mediterranean clades. All these patterns are postulated to result from both temperature changes during the last glacial and contemporary sea currents. No geographic AFLP structure was revealed in C. soldanella, both at the range-wide and population level. This was attributed to the remarkable seed dispersal ability of this species and possibly its longevity and clonal growth, preserving a random pattern of genetic variation generated by long-distance seed dispersal over long time periods.

Temperatur- und ortsabhängige Zustandsdichte des organischen Supraleiters Kappa-(BEDT-TTF) 2 Cu[N(CN) 2]Br

Im Rahmen dieser Arbeit wurde die temperatur- und ortsabhängige Zustandsdichte des organischen Supraleiters kappa-(BEDT-TTF)2Cu[N(CN)2]Br mit Rastertunnelspektroskopie bei tiefen Temperaturen untersucht.rnZusätzlich zur bereits bekannten supraleitenden Energielücke wird dabei eine logarithmische Unterdrückung der Zustandsdichte an der Fermikante beobachtet, die auch oberhalb der kritischen Temperatur erhalten bleibt. In der vorliegenden Arbeit wird gezeigt, dass sich dieses Verhalten durch ein für ungeordnete elektronische Systeme entwickeltes Modell unter Berücksichtigung von Coulomb-Wechselwirkungen beschreiben lässt. Die daraus resultierenden Fluktuationen der elektronischen Struktur führen zu einer Verbreiterung der gemessenen supraleitenden Energielücke, die sich durch sehr kleine Kohärenzmaxima im entsprechenden Quasiteilchenanregungsspektrum äußert. Dieses Verhalten wurde bereits beobachtet, konnte jedoch bisher nicht erklärt werden. Die theoretische Beschreibung der logarithmischen Unterdrückung trägt somit zusätzlich zum Verständnis des supraleitenden Beitrags bei, sodass die gesamte Zustandsdichte vollständig beschrieben werden kann. Die Analyse der gemessenen supraleitenden Energielücke wurde für verschiedene Symmetrien des Ordnungsparameters durchgeführt, wobei die beste Übereinstimmung für die Annahme einer d-wellenartigen Symmetrie mit zwei unterschiedlich stark ausgeprägten Energielücken gefunden wurde. Der Paarbildungsmechanismus, der zur Bindung zweier Elektronen zu einem Cooper-Paar führt, kann mit einer $d$-wellenartigen Symmetrie nicht durch die in konventionellen Supraleitern gefundene Elektron-Phonon-Kopplung erklärt werden. Stattdessen wird in Analogie zur Hochtemperatur-Supraleitung eine durch antiferromagnetische Spin-Wechselwirkungen induzierte Kopplung der Elektronen vermutet. Dies wird zum einen durch die oberhalb der kritischen Temperatur auftretende, zweite Energielücke und zum anderen durch die zwischen 4,66 und 5,28 liegende Kopplungsstärke 2Delta/(kB Tc) unterstützt, die deutlich größer als für konventionelle Supraleiter mit Elektron-Phonon-Kopplung ist.
