Hidrogeoquímica do aqüífero guarani na área urbana de ribeirão preto (SP)

This work evaluated the hydrogeochemistry of the Guarani Aquifer in the urban area of Ribeirão Preto, São Paulo State. Thirty one sampling points were established and it was carried out field campaigns in 7 and 8 July 2005, analyzing the following parameters: conductivity, temperature, pH, turbidity, color, dry residue, dissolved oxygen, Ca2+, Mg2+, Na+, K+, Fe3+, Al3+, HCO3-, SO42-, PO43-, NO3-, Cl- and F-. The results indicated that the groundwaters in the urban area of Ribeirão Preto pH possess slightly acid, low conductivity, turbidity, color and dissolved oxygen inside the limits established for drinking waters. The ionic composition indicated that the groundwaters have low cations and anions concentration, being they classified as soft water and calcium-bicarbonated. Statistical tests suggested that conductivity and pH are controlled for the calcite dissolution (CaCO3) during the water/rock interaction process. Besides, it is possible to conclude that the high NO3- and PO43- concentrations found in the groundwater in the urban area of Ribeirão Preto are originated due to anthropogenic activities.

Concepções de surdez: A visão do surdo que se comunica em língua de sinais

At this time, diverse views on deafness are present in society. Such views, in general, arecharacterized by theoretical disputes between communicative possibilities - either oral or gestural - based onthe importance of having appropriated oneself of a language code for the development of language, which isessential in the constitution of subjectivity of human beings. Thus, this study aimed to identify the conceptionsof deaf people had about their condition. To collect the data we used semi-structured interviews, applied toten participants who were deaf adult users of the Brazilian Sign Language - Libras. The interviews were taped,transcribed and subjected to content analysis. The results indicate that the conceptions of deafness constitute amultifaceted view on this condition, infl uenced by social relations throughout each person's life trajectories. Theresearchers perceived that learning Libras enabled deaf persons to constitute their own assertiveness as someonewho is different, with different needs.

A variedade léxica da língua espanhola em dicionários bilíngues espanhol-português para aprendizes brasileiros

Due to factors such as globalization and the demography of Hispanic countries, the Spanish language has influenced worldwide, especially since the last decade of the 20th century, mainly countries which are geographically close to Spanish American countries, such as Brazil. In this context, it is necessary to think of the linguistic variation of the Spanish language, in which we emphasize the lexical variation. As any language, Spanish has a colossal and wealthy lexicon with different varieties related to the characteristics from each region: history, culture, customs etc. This diversity influences the development, the amplification and the renewal of a language, as well as the teaching-learning process. Thus, we proposed to analyze the lexicon varieties of Spanish language entries in some Spanish-Portuguese bilingual dictionaries for Brazilian learners. In order to achieve this goal, we selected some examples of lexical variety in a corpus organized with texts of different textual genres and we verified if these lexical items are registered in the dictionaries chosen. As the corpus is organized from texts present in didactic manuals used in Brazil, our goal is to verify if the vocabulary which the Brazilian learner has contact in formal education is registered in the analyzed dictionaries.

Geotermometria das águas hipertermais do Sistema Aquífero Guarani no estado de São Paulo

Several geothermometers have been employed to determine the expected temperature in the groundwater reservoirs, most part of them based on the chemical equilibrium between thermal groundwaters and minerals which constitute the aquifer framework. Based on this principle, groundwater from Guarani Aquifer System, which presents temperatures upon to 38°C, classified as hyperthermal by the Brazilian Mineral Water Code, had their chemical composition evaluated with the main purpose to determine the expected temperatures in the reservoir based on the application of several geothermometers. These groundwaters can be classified as Na-HCO3 type evolving to Na-HCO3-Cl-SO4 type due the increase in sulphate and chloride concentrations. Measured groundwater temperatures show a good correlation with the depth of the aquifer, indicating an average geothermal gradient of 27.7°C/km. The lowest geothermal gradients, bellow 25°C/km, are observed in the central portion of the study area; meanwhile the highest gradients are observed in NE and W portions of the study area. Quartz equilibrium based geothermometers return temperature over the measured temperatures, meanwhile chalcedony geothermometer returns temperatures near the measured in the wells, except for the wells located in the area which presents the lowest geothermal gradients. The geothermometers based on the equilibrium between Na/K have returned temperatures diverse from the measured at the field, meanwhile the geothermometer based on the equilibrium between Na/K/Ca has presented good match with groundwater which present temperatures under 50°C, due the thermodynamic equilibrium between these waters and feldspars. Geothermometers show evidences about mixtures between groundwaters from GAS and underlying units, especially in wells located in the SW portion of the study area.

O processo de conscientização na sala de aula de língua espanhola

This article discusses the awareness process of students in a Spanish as a foreign language classroom, at a Centre of Language Studies in a city in the state of São Paulo, Brazil. The frame of reference is Paulo Freire's pedagogy (FREIRE, 1980, 1984, 1987, 1999, 2000), Wallerstein (1983) and Schleppegrell (1997)'s investigations which are important to the comprehension of the relation between Freirean's pedagogy and the language teaching. This is a qualitative research and it focuses on action research practice in a Spanish language classroom, in which a syllabus based on Paulo Freire's pedagogy was implemented in order to verify how the target language was used in the classroom (MENEGHINI, 2001). Data analysis and discussion are based on data triangulation and classroom interactions are taken on primary data. The implementation of this research suggests that the problem posing tasks on themes chosen from the student's realities are the way which leads to the awareness.

High-resolution aquifer analog of fluvial-aeolian sediments of the Guarani aquifer system

The Guarani aquifer system (GAS) represents one of the biggest aquifers in the world and is the most relevant groundwater resource in South America. For the first time, by combining field and laboratory measurements, a high-resolution aquifer analog model of fluvial-aeolian sediments of the GAS in São Paulo State (Brazil) is constructed. Three parallel sections of frontal outcrops, 28 m × 5.8 m, and two parallel sections of lateral outcrops, 7 m × 5.8 m, are recorded during open-pit mining of sandy sediments and describe in detail the three-dimensional distribution of the local lithofacies and hydrofacies. Variations of hydraulic conductivity, K, and porosity, n, are resolved on the centimeter scale, and the most permeable units of the fluvial-aeolian facies association are identified. The constructed aquifer analog model shows moderate hydraulic heterogeneity and a mean K value of 1.36 × 10-4 m/s, which is greater than the reported range of K values for the entire GAS in São Paulo State. The results suggest that the examined sedimentary unit constitutes a relevant portion of the GAS in São Paulo State in the context of groundwater extraction and pollution. Moreover, the constructed aquifer analog is considered an ideal basis for future numerical model experiments, aiming at in-depth understanding of the groundwater flow and contaminant transport patterns at this GAS portion or at comparable fluvial-aeolian facies associations. © 2013 Springer-Verlag Berlin Heidelberg.
