Construções com tópico marcado em cartas pessoais brasileiras dos séculos XVIII, XIX E XX

This dissertation is a research on the marked topic construction (CT) in Brazilian personal letters from eighteenth, nineteenth and twentieth centuries. The goal of our research is to verify if CT are present in the writing of Brazilians born in the centuries in question. Our research focus is based on the assumptions of generative theory (CHOMSKY 1981; 1986), which states that grammar is internalized in the mind / brain of the writers, with the emphasis on studies of grammatical change, as pointed texts by Paixão de Sousa (2004), Carneiro (2005); Galves, Namiuti and Paixão de Sousa (2006) and Martins (2009). Our corpus was extracted from Projeto Para a História do Português Brasileiro (PHPB) and Cartas Brasileiras coletânea de fontes para o estudo do português. We selected forty-six correspondents who should be inserted into the two criteria set out in this research: to be Brazilian and be born in the centuries mentioned above, so that we could find legitimate topic constructions of PB. This work is based on researches by Pontes (1987), Mateus et al. (2003), Araujo (2006, 2009), Berlinck, Duarte and Oliveira (2009), which actively support us in the study of this linguistic phenomenon in Portuguese. The results show that the marked topic construction in our corpus appear on the writing of Brazilians since the second half of the eighteenth century, while the typical constructions in Brazilian Portuguese locative topic, subject topic and copy topic - are already reflected in the I-language of the writers born in the second half of the nineteenth century and the first of the twentieth century

Efeito da estrutura etária nas taxas de homicídios em regiões metropolitanas brasileiras (Natal - Recife - São Paulo)

Este estudio examina el fenómeno de asesinato, desde la perspectiva de cambiar la estructura de edad de la zona metropolitana de Natal, Recife y Sao Paulo, utilizando los datos del Sistema de Información de Mortalidad-SIM/DATASUS, del Ministerio de Salud. Se llevaron a cabo ejercicios teóricos estandarización directa con las estructuras de diferentes edades para evaluar el efecto de los cambios en la estructura de la población en las tasas de mortalidad por homicidio. Los resultados presentados en las pirámides de edad y las cartas apuntan a la población de edad avanzada en las tres áreas metropolitanas de la serie analizada, así como las que muestran un mayor riesgo de victimización en las personas, hombres, de edades comprendidas entre 15 y 39 años. Hemos utilizado diversos ejercicios de las tasas de homicidios con patrones estandarizados de distintas edades, incluyendo una población proyectada para el año 2020 de la Región Metropolitana de São Paulo, cada vez más evidente que cuando la población se vuelve más edad con menos gente en los grupos de mayor riesgo tienden a tener menores tasas de muertes por homicidio, también puede presentar otros resultados siempre la misma línea de razonamiento

Evaluation of ten tropical grasses in the northwest region of the state of Sao-Paulo Brazil

The experiment was carried out in the northwest region of the State of São Paulo-Brazil to evaluate ten grasses recently introduced in the region. The grasses studied were: Cynodon nlemfuensis cv. Tifton 68, C dacrylon cv. Tifton 78, Cynodon spp. cv. Tifton 85, C. dactylon cv. Florakirk, C. nlemfuensis cv. Florico, C nlemfuensis cv. Florona, C dactylon cv. Coastcross, Paspalum notation cv. Tifton and NDF (717 to 749 g.kg(-1)) were observed in the Cynodon cultivars while lower values of CP (102 and 107 g.kg(-1)) and NDF (697 and 705 g.kg(-1)) were registered in the cvs. Marandu and Tanzania 1. The contents of ADF were higher in the the cvs. Tanzania 1 and Tifton 9. The average values of IVDMD differed (Ppound0.05) among grasses and were all above 564 g.kg(-1), except for cv. Tifton-9 (499 g.kg(-1)). The results obtained in this work allowed to conclude that the cvs. Tifton 78, Tifton 85, Coastcross, Florona, and Tanzania 1 are interesting options for pastures establishment in the northwest region of the State of São Paulo-Brazil.

Chemical composition of tropical macrophyte Echinochloa polystachya (HBK) Hitchcock in Jurumirim Reservoir (Sao paulo, Brazil)

Seasonal variations of C, N and P concentrations and stocks in the emergent macrophyte Echinochloa polystachya (H.B.K.) Hitchcock, of the Paranapanema River mouth zone at Jurumirim Reservoir (SP, Brazil), were examined. Marked variation in nutrient concentrations (from 287.6 to 463.2 mg C g DW-1; 3.4 to 37.8 mg N g DW-1; 0.13 to 2.31 mg P g DW-1) and stocks (from 3.8 to 11.9 t C ha(-1); 96.3 to 400.6 kg N ha(-1), 3.6 to 44.3 kg P ha(-1)) were observed along the year (August 1993 - July 1994). Peaks in concentrations and stocks were observed in January, February and March 1994. As nutrient concentrations in water and sediments are low and stocks in the plant high, the local nutrient dynamics seem to be controlled by this macrophyte. Leaf blades and sheaths participate most in recycling, while stems contain the principal nutrient stock.

Biology and shell relationship in Clibanarius vittatus (Bosc, 1802) (Crustacea, Diogenidae) from Sao Vicente, SP, Brasil.

This study aimed to characterize the populational structure of Clibanarius vittatus (Bosc, 1802), as well as to determine the morphometric relations between the animal's size and the variables: length of their chelar propodus and the size of the shell opening. C. vittatus is a relatively abundant pagurid on the west Atlantic coast, it occurs in the intertidal region from 38 degrees N to 28 degrees S. The animals in this study were randomly sampled every month on the Paranapu (a) over tilde Beach (46 degrees 23' S e 23 degrees 59' W), S (a) over tilde $ o Vicente (SP), Brazil. The biometrics data were adjusted to the power equation (y = ax(b)), by means of the minimum square method. A total of 427 individuals were collected. The size of the cephalothoraxic shield ranged from 2.5 to 12.7 mm, evidencing a representative sample of the population. The of most commonly genus of Gastropoda shells occupied by the hermits was Thais (97,26%). In relation to the morphometric analyses performed, it was observed a positive correlation between the animal size and the variables length of the chelar propodus and the size of the shells.

A model for the plankton system of the Broa reservoir, Sao Carlos, Brazil

In this paper a model, called ELLOBO running in STELLA II, was set to describe the plankton system of the Broa reservoir (SP). The three state variables of the model are: phytoplankton, zooplankton, and the fish Astyanax fasciatus. The forcing variables are: temperature, nitrate, phosphorus and solar radiation. The model did not consider the cycling of nutrients inside the reservoir. The results show that: temperature is the principal forcing variable in the phytoplankton dynamic and in the subsequent evolution of the whole system. The zooplankton predation was described by Odum's equation, and there is a strong random component in zooplankton grazing, which was essential for the model, because zooplankton estimates have high variance. One must collect data in a short space of time (maybe daily) to better explain the zooplankton and phytoplankton variation. Validation was performed using simple statistics (arithmetic mean, standard deviation) and the results show concordance between observed and simulated values. Overhead was used to calibrate some parameters and to validate the model. The highest overhead value (5%) imply in the better accordance between estimated and;observed state variables values. We believe this approach in Broa reservoir will provide an useful tool for future research and it could be used comparatively in other continental aquatic ecosystems. (C) 2000 Elsevier B.V. B.V.

Social and financial aspects of the artisanal fisheries of Middle Sao Francisco River, Minas Gerais, Brazil

The presence or absence of motorized boats, partnerships and multispecies catches characterize the fisheries of Sao Francisco River, Minas Gerais, Brazil. Fishing activity based on 109 interviews, carried out in the wet (high water: February and March) and dry (low water: July and August) seasons, with professional fishermen are described. Aiming to identify the fishery income components, a covariance model was proposed, with the income as the response variable, related to the factors: fishing ground, use of motorized or paddle boat; seasonality; presence of fishing assistant, and the following covariates: capture in weight in the week Frier to the interview, fisherman experience in yrs; and distance (km) travelled for fishing. The results indicated that the main contributions to income were the absence of an engine (because of high price of the fuel), the absence of a partner (because of low capture) and the amount of fish caught by the fishermen.

Diversity and distribution of crustaceans from 13 sheltered sandy beaches along Sao Sebastiao Channel, south-eastern Brazil

The crustacean species composition in the intertidal zones of 13 sheltered unconsolidated marine beaches in south-eastern Brazil is described. Fifty-three crustacean species were collected, adding 46 species to the total reported by previous studies in the same region. Decapods dominated the community, in contrast to exposed sandy beaches where peracarids normally predominate. The species were distributed irregularly among the beaches. Richness varied markedly among sites, and was positively related to a combination of factors such as fine sand grains, high organic matter content, and relatively low silt-clay content. The presence of rock fragments enabled both rocky shore and sandy beach crustaceans to occur oil the same beaches. Richness and abundance of crustaceans showed no clear relationship to sediment grain size and slope, in contrast to the norm for exposed sandy beaches. The dominance of the tanaid Kalliapseudes schubarti in sonic areas may be a result of organic matter pollution in the region. These beaches showed higher species richness than typical sheltered and exposed sandy beaches, indicating that this sheltered, highly heterogeneous seascape is an important area for conservation.

Resources Taken to the Nest by Protopolybia exigua (Hymenoptera, Vespidae) in Different Phases of the Colony Cycle, in a Region of the Medio Sao Francisco River, Bahia, Brazil

The present study aimed to identify what resources were taken to the nest by workers of Protopolybia exigua (de Saussure), to verify if there is a relationship between physical factors of weather and phases of colony development and the collection of different resources and also to observe if the wasps carry macerated prey in the crop. The species collected nectar (62.8%), wood pulp for nest building (6.1%), water(2.9%), prey (0.8%) and resin (0.2%). Moreover, workers of P exigua do carry macerated prey in the crop. There was a positive correlation (r = 0.85, p = 0.0004) between the presence of larvae in the nest and the carrying of solid contents in the crop, which provides strong evidence that this species macerates its prey while still in the field, before taking it to the nest. There was positive influence of the temperature on the collection of nectar (r = 0.89, p = 0.0001) and water (r = 0.46, p = 0.0066) and negative influence of relative air humidity on the collection of the same resources (r = - 0.88, p = 0.0001 and r = - 0.37, p = 0.0160, respectively). Luminosity influenced the gathering of water (r = 0.43, p = 0.0089) and Pulp for nest building (r = 0.31, p = 0.0274) and the wind speed did nor influence the collection of any resources. Nectar is the main item taken to the nest during all phases of the colony.
