Atos discursivos interativos nas variedades do português falado

This paper aims to analyze and to characterize the structure of some linguistic expressions that, in the view of Functional Discourse Grammar (HENGEVELD; MACKENZIE, 2008), are called Interactive Acts because they show the Speaker, the Addressee and the Illocution positions filled in. To do so, we analyse data composed of representative texts of Portuguese spoken in Portugal, in Brazil, in African countries (those that have Portuguese as official language) and in East Timor

A new Coniacian-Santonian conchostracan genus from the Bauru Group, south-east Brazil: Taxonomy, palaeobiogeography and palaeoecology

Abundant conchostracans occur in Coniacian-Santonian dark grey, argillaceous, lacustrine sediments of the Sao Carlos Formation, Bauru Group, Parana Basin, in the central part of São Paulo State, south-east Brazil. They are ascribed to a new genus and species, Bauruestheria sancarlensis, included in the family Jilinestheriidae. The new taxon is similar to some Late Cretaceous species from China and Mongolia. It probably evolved from a Late Jurassic-Early Cretaceous ancestral form (Migransia), which first lived in West Gondwana, and later dispersed to Europe and Asia, originating distinct parallel lineages with increasing ornamental complexity. The conchostracans probably lived in oxygenated marginal areas of a very calm, perennial lake with an anoxic bottom, and were transported in suspension to the depositional site by weak turbidity currents or storm-induced flows. Great concentrations of juvenile conchostracans in some thin layers can be related to mass mortality, episodes caused by convection and dispersion of anoxic water during storms.

Produtividade e resistência à ferrugem do cafeeiro (Hemileia vastatrix BERK. ET BR.) de progênies F5 de catuí amarelo com o híbrido de timor

Foram estudadas 18 progênies na geração F5 do híbrido H 419, provenientes do cruzamento entre o Híbrido de Timor (UFV 445-46) e o Catuaí Amarelo IAC 30 (UFV 2143), 5 progênies na geração F5 do híbrido H 516, proveniente do cruzamento entre o Híbrido de Timor (UFV 446-08) e o Catuaí Amarelo IAC 86 (UFV 2154) e como controle o Catuaí Vermelho IAC 44 ( UFV 2144 ) com e sem controle da ferrugem. em relação a produção de café cereja por planta e ao ataque da ferrugem as progênies H419-3-1-1-14 e a H516-2-1-1-18, foram as que apresentaram maiores produtividades e resistência a ferrugem ( nota 1 ), seguidas da H419-6-3-6-12, porém com resistência parcial à ferrugem. Essas progênies também foram as que apresentaram maior comprimento do ramo plagiotrópico, que influenciou em 37,73% (R²) na produção de café cereja por planta. O comprimento do ramo plagiotrópico, diâmetro do tronco e altura das plantas foram os atributos que mais correlacionaram r= 0.5977, r= 0.3316 e r= 0.2848, respectivamente p< 0.01, com as produtividades dessas progênies, concordando com resultados obtidos por Dhaliwal (1968). em relação a resistência ao fungo Hemileia vastatrix Berk. et Br.,as progênies apresentaram herdabilidade no sentido amplo elevada (h a² = 0,80 entre e h a² = 0,96 entre e dentro das progênies), mostrando variabilidade genética alta para seleção de material resistentes à ferrugem do cafeeiro.

A new titanosaur from western São Paulo State, Upper Cretaceous Bauru Group, south-east Brazil

Material from a new titanosaur from the Bauru Basin (Bauru Group), Brazil is described and compared with well-known titanosaurs. Adamantisaurus mezzalirai gen. et sp. nov. is based on six articulated anterior caudal vertebrae and two haemapophyses collected from the Adamantina Formation, which is considered to be Campanian-Maastrichtian? in age. Adamantisaurus mezzalirai is characterized by the following combination of characteristics: anterior caudal vertebrae with straight or slightly backwardly-projecting neural spines with strongly expanded distal ends, stout prespinal lamina, very wide pre- and postzygapophyseal articular facets, and concave postzygapophyseal articular facets on anterior caudal vertebrae. Although our cladistic analysis has produced equivocal results, Adamantisaurus mezzalirai shares with DGM 'Series B' (Peiropolis titanosaur) and Aeolosaurus the presence of postzygapophyses with concave articular facets, and shares with DGM 'Series B' the presence of laterally expanded neural spines and stout prespinal lamina. Additionally, A. mezzalirai shares with DGM 'Series' C (other titanosaur from Peiropolis) the presence of short neural spines.

Geological evolution of the basement rocks in the east-central part of the Rondonia Tin Province, SW Amazonian craton, Brazil: U-Pb and Sm-Nd isotopic constraints

On the basis of geologic, petrologic, and U-Pb geochronologic data the basement rocks in the east-central part of the Rondonia Tin Province (RTP, southwestern Amazonian craton) are grouped into five lithologic associations: (1) tonalitic gneiss (1.75 Ga); (2) enderbitic granulite (1.73 Ga); (3) paragneiss; (4) granitic and charnockitic augen gneisses (1.57-1.53 Ga); and (5) fine-grained granitic gneiss and charnockitic granulite (1.43-1.42 Ga). The first three are related to development of the Paleoproterozoic Rio Negro-Juruena Province and represent the oldest crust in the region. The tonalitic gneisses and enderbitic granulites show calc-alkaline affinities and Nd isotopic compositions (initial epsilon(Nd) = +0-1 to -1.5; T-DM of 2.2-2.1 Ga) that suggest a continental arc margin setting for the original magmas. The paragneisses yield T-DM values of 2.2-2.1 Ga suggesting that source material was primarily derived from the Ventuari-Tapajos and Rio Negro-Juruena crusts, but detrital zircon ages and an intrusive granitoid bracket deposition between 1.67 and 1.57 Ga. The granitic and charnockitic augen gneisses show predominantly A-type and within-plate granite affinities, but also some volcanic arc granite characteristics. The initial epsilon(Nd) values (+0.6 to +2.0) indicate mixing of magmas derived from depleted mantle and older crustal sources. These rocks are correlated to the 1.60-1.53 Ga Serra da Providencia intrusive suite that reflects inboard magmatism coeval with the Cachoeirinha orogen located to the southeast. The fine-grained granitic gneiss and charnockitic granulites represent the first record of widespread magmatism at 1.43-1.42 Ga in northern Rondonia. Their geochemical signatures and the slightly positive initial epsilon(Nd) values (+0.7 to +1.2) are very similar to those of the most evolved granites of the calc-alkaline Santa Helena batholith farther southeast. U-Pb monazite and Sm-Nd whole-rock-garnet ages demonstrate that a high-grade tectonometa-morphic episode occurred in this region at 1.33-1.30 Ga. This episode attained upper-amphibolite conditions and is interpreted as the peak of the Rondonian-San Ignacio orogeny. The U-Pb and Sm-Nd data presented here and data published on rapakivi granites elsewhere indicate that the east-central part of the RTP is a poly-orogenic region characterized by successive episodes of magmatism, metamorphism, and deformation between 1.75 and 0.97 Ga.

Range extension for buff-fronted owl Aegolius harrisii in south-east Brazil.

Buff-fronted Owl Aegolius harrisii is a poorly known species. Field records are rare and sparse, with large gaps throughout its distribution. We present five new records of A. harrisii in south-east Brazil, in the states of São Paulo and Minas Gerais, and the second ever nest description. In São Paulo, records from Franca are >300 km from previous records, while the new record in Minas Gerais is 600 km from the only previous state record. More nocturnal field work is required to better evaluate the true distribution of A. harrisii.

Incidence of Leptospirosis infection in the East Zone of Sao Paulo City, Brazil

Background: Leptospirosis is a zoonosis which is spread through contamined running water. This contaminations is seriously affected by the flooding which occurs in the area surrounding the Aricanduva river. The transmission of the disease results mainly from the contact of water with soil contaminated by the urine of infected animals. We aimed to conduct an epidemiological survey on Leptospirosis cases in Sao Paulo East Zone area. Method. The analysis conducted in this study was based on data collected from the health authorities of that region close the Aricanduva river between 2007 and 2008 years, which give the rates of confirmed cases, mortality and death from human Leptospirosis. Other information concerned with the relationships among rainfall index, points of flooding and incidence of Leptospirosis. Results: We observed a direct and important water contamination. Records of flooding points and dates of the reported cases in the region showed a direct relationship from which the period of higher rainfall also recorded an increase in cases. The annual record of the city and the region and rainfall regions also presented correlation. Conclusion: The association between the indices of flooding and Leptospirosis cases indicates that preventive measures are necessary to avoid exposing the community. © 2013 Miyazato et al.; licensee BioMed Central Ltd.
