A influência das características morfométricas e de uso da terra na morfodinâmica: um estudo da alta bacia do Rio Itanhaém - Baixada Santista/SP

Diante do desenfreado uso da terra, gerando impactos muitas vezes irreversíveis, o planejamento ambiental insere-se como uma ferramenta atualmente necessária. Visto que é sob o relevo que se consolidam as atividades antrópicas, a cartografia do relevo surge como um importante instrumento, indicando setores cujas características naturais impõem limites ao uso da terra. Assim, o objetivo desta pesquisa é analisar as características geomorfológicas da alta bacia do Rio Itanhaém, com ênfase à questão morfográfica e morfométrica do relevo, avaliando também as modificações impostas a este em decorrência do uso da terra, contribuindo, portanto, com a gestão ambiental desta área. Para tanto, foram elaborados documentos cartográficos capazes de evidenciar as características do relevo que impõem limites ao uso antrópico, a saber: as cartas morfométricas (carta de declividade, carta de dissecação vertical, carta de dissecação horizontal e carta de energia do relevo), que são documentos que evidenciam a suscetibilidade potencial do relevo sob a influência da ação das águas e gravitacional; a carta geomorfológica (cenário de 1962), que possibilita a espacialização das formas do relevo, contribuindo para a análise da morfodinâmica; e as cartas de uso da terra (cenário de 1962 e 2000), que, em conjunto com os documentos já especificados, possibilitam a análise da influência da atuação antrópica sob o sistema relevo. De maneira geral, pôde-se detectar problemas na morfodinâmica da área de estudo, evidenciados pela presença de feições denudacionais localizadas, tais como sulcos erosivos, voçorocas, ravina e cicatrizes de escorregamentos, os quais vinculam-se ao potencial natural que o relevo da área de estudo possui ao desencadeamento de processos morfogenéticos; à dinamização de processos naturais pela atuação antrópica...

Geotecnologias para a análise da bacia hidrográfica do Córrego Wenzel - Rio Claro/SP: proposta de gestão de recursos hídricos

The expansion of urban in medium-sized citie, increase the importance of action planning and management of natural resources, among which water is the most important. Such action should include the integration of physical and man-made elements involved. In this context, it becomesimportant for watershed analysis and the use of geotecnologies. Thus, the objective was to demonstrate the contribution of the geo, as a tool for managing a river basin, allowing the integration of physical data and the analysis of anthropogenic environmental scenarios in urban areas. The area chosen, the basin of the Wenzel, is located in Rio Claro / SP, a city whose urbanization process has been intense and continuous. Thematic maps were generated from the physical environment: soil, slope and geological, as well as maps of land use. With regard to land use maps, these were drawn from the visual interpretation of material aerophotogrammetric, considering the years 1995 and 2010, performing an evolutionary analysis. It was observed that the area presents small variation in the physical and structural aspects, with lithological and geomorphological formation favoring the occurrence of floods, erosion and siltation. These processes are accelerated by the forms of land use, with intense urbanization during the period between 1995 and 2010, and poor preservation of permanent preservation areasand. In the floodplain areas there is a high waste disposal is the most notable environmental problem

o ensino de leitura na escola: um olhar sobre as concepções de professores do 1º ciclo do ensino fundamental de uma escola municipal de Bauru - SP

This research is being read, thus rendering text on the pole of understanding, as a practice effective dialogue and therefore responsive through which the reader, author, text and context interact. To this end, the reader must turn their knowledge systems and relate them to the linguistic materiality. Thus, aimed to investigate whether the teaching of reading in the early years of elementary school literacy builds skills related to this cultural practice and its relationship to the conceptions of classroom teachers of reading, as well as the teaching and learning methodologies practiced in class classroom. Therefore, I base this research on the theoretical basis of linguistic studies and expository sociointeractionist redefine that, among other things, the concepts of language, genre and text. As for the methodological framework, this study followed the methodology of literature research and fieldwork. The fieldwork took place from the perspective of observing the pedagogical practice of teaching reading, in order to investigate how the educational activities are conducted in a reading room for the third year of elementary school, part of the municipal education Bauru- SP. Were used as instruments of data collection the questionnaire given to school teachers and the school studied the direct observation of teaching practice of one of these professionals. The results of data analysis indicate that the teachers surveyed know key content for teaching reading, as well as renovations of the theoretical and methodological studies of reading, with the consequence that the practices of reading done in the classroom limit the role of student as a reader and does not guarantee the formation of the reader

Fácies, diagênese e arquitetura estratigráfica de reservatórios deltaico-lacustres da fase rifte (formação pendência), campo Serraria da Bacia Potiguar

Of the four lacustrine deltaic models, which were found in the Pendência formation, two are represented in the Serraria field. Respectively the deltaic models 1 and 3 shows the reservoir zones A and B. The Zone A is divided into six sub-areas. Each is representing a smaller cycle of development of sigmoidal lobes of deltaic front. Zone B produces in reservoirs of Model 3, or so called Full delta. The Zone B is formed by overlapping the deltaic plain system over the deltaic/prodeltaic front (model 1). This work uses the method of zooming with the aim to contextualize the geometric aspects of the sand bodies, highlighting the analysis of facies and diagenesis with help of pictures and testimonies of thin sections. The sigmoidal lobes of Zone A are fine to very fine sandstones, well sorted, with a arcosian composition.;practically with a weak compaction and cementation of a kind of film of clay (if very fine) and overgrowth feldspar (fine texture). This silicate phases are succeeded by cementation of poiquilotópica calcite, and after this a stage of dissolution, containing only regular permoporosity for this reservoir. Zone B has a combination of two types of deltaic plain reservoir. One is the rarest of distributary channel and the other the most common of lobes of crevasse. In the channel coarse to medium-grained and poor to moderate sorted sandstones are formed (tuning up), and with a lytic arcosiana nature. Rarely there are cements, including growth of feldspar and rhombohedral dolomite, which prevent a high permoporosity of the reservoir. In the crevasse lobes, the sandstones are laminated, fine and well sorted, arkosic, rarely with overgrowth feldspar and calcite poiquilotópica, and with a good intergranular permoporosity

Estudo da distribuição e das densidades larvais do bivalve invasor Limnoperna fortunei (Dunker, 1857) nos principais corpos d’água da bacia do rio da Prata

O mexilhão-dourado (Limnoperna fortunei) é um bivalve de água doce pertencente à família Mytilidae. Originário de rios e arroios da China e do sudeste asiático, foi introduzido acidentalmente na América do Sul em 1991, no estuário do rio da Prata, provavelmente através de água de lastro. Como encontrou condições propícias para o seu desenvolvimento, se expandiu através dos rios Uruguai, Paraná e Paraguai, sendo atualmente o principal responsável pelo macrofouling em ecossistemas de água doce do continente. O presente estudo compreende uma área de grande extensão na bacia do Rio da Prata, onde foram amostrados pontos estratégicos nos rios Paraná (e seus principais afluentes), Uruguai e Paraguai. A partir de coletas de organismos do plâncton, realizadas por arrasto vertical, foram quantificadas as densidades de larvas de L. fortunei em cada local de amostragem. Assim, obteve-se um panorama atual da ocorrência do mexilhão, registrando-se, inclusive, alguns limites de sua distribuição. As densidades mostraram-se, no geral, elevadas, provavelmente em decorrência do período de amostragem (verão 2010), onde a atividade reprodutiva da espécie é maior devido às altas temperaturas. Porém, grandes variações ao longo da bacia foram registradas, o que pode estar relacionado ao grau de antropização, disponibilidade de substratos, velocidade da corrente, tempo de introdução, entre outras variáveis

A escolha da profissão docente: perfil dos alunos do curso de Pedagogia da UNESP/Bauru no ano de 2011

Several aspects interfere when it comes to choose a career. Some of which are family and cultural influence; and even lack of opportunities. Such aspects were greatly taken into consideration for defining the subject of this research which is to analyze the reasoning Pedagogy students from UNESP (Universidade Estadual Paulista – University of São Paulo State) used when choosing their academic career, and to assess the students’ profile who were taking this course in 2011 as well as the influence of students’ socioeconomic conditions. An empiric approach with a qualitative survey was chosen to develop this research which was conducted with a questionnaire appliance and with a semi-structured interview with randomly selected students. A theoretical study about the specifics of the academic career and a fully comprehension of the legal / regulatory aspects of this profession in Brazil were also conducted. The survey results showed that most students were women, supporting the fact that this career has become a female profession. Characteristics such as vocation and mission, presented on literatures as the specifics of this profession were clearly seen in the survey results. Several students went to public schools and are labeled into the classes C and D in social economical status; furthermore almost 50% had not chosen Pedagogy as a first choice for a major. However, most of the students do not think that their social economical status had influence in their choice. Nevertheless some students claimed that their options were not their first wish and their choice was made by the easier possibility of entering and concluding the course besides the prompt need of these professionals after graduating in the job market. The students’ education background were also discussed in the research... (Complete abstract click electronic access below)

Avaliação das taxas de erosão química e física na bacia hidrográfica do Ribeirão Jacutinga (SP)

Currently with the growing technological advancement and global, new areas are being devastated, and as a result, the erosion became more frequent causing loss of soil, infiltration capacity of the surface and weathering of rocks. In this way, environmental studies are increasingly frequent to understand the environment in which we live, but also to avoid any degradation of the same and of finite natural resources, which are essential for human life. From this, this work has as main goal, analyzing the rates of chemical and mechanical erosive watershed of Ribeirão Jacutinga, at its mouth, in the city of Rio Claro, supporting environmental studies and sustainable development today. Order to reach these values were measured and total dissolved solids in suspension in the stream during the months from January to July 2012. As results included higher rates of both physical and chemical weathering in the rainy months, especially january

Perfil epidemiológico dos pacientes internados na unidade de tratamento de queimaduras do Hospital Estadual de Bauru

Burns are frequent accidents, and they are among the major causes of morbidity and mortality in our society. In Brazil, statistical data on such lesions are relatively scarce, and they are concentrated in a few treatment centers. Data on such accidents allow for specific care to be timely and properly taken in order to provide patients with a better prognosis, in addition to enabling the development of prevention programs as well as fire-prevention safety laws. To characterize the epidemiological profile of users at the Burn Treatment Unit of Bauru State Hospital. Collection of epidemiological data through the e-pront system and from charts of burned inpatients from April 2005 to April 2010. During the studied period, 906 hospitalizations of burned patients occurred, with an annual average of 181.2 individuals. Their mean age was 28.4 years, with a predominance of males. The mean hospitalization period was of 27.6 days, with a median of 16 days and a maximum of 216 days; 14.7% developed to death, with the highest mortality rate in the first two weeks of hospitalization. Second-degree burns were the most frequent; 36.8% of the patients burned less than 10% of their body surface, and there was a gradual frequency reduction when a larger burned surface was taken into account; the greater the affected areas, the higher the number of deaths; 91% resulted from thermal agents, 6% from electric and 2% from chemical agents; scalding was the major cause among all agents, followed by alcohol associated with fire and direct flame. The major area affected areas were the upper limbs. The study shows the need for educational and preventive measures, particularly for the young adult population, by means of educational programs and prevention campaigns

Diversidade genética por marcadores microssatélites de progênies de Tabebuia heptaphylla da região da bacia do médio Tietê

Os recursos genéticos existentes, atualmente, são de suma importância para garantir a preservação de espécies florestais, uma vez que parte delas vem sofrendo excessiva exploração por se tratar de espécies economicamente importantes ou simplesmente devido à ação antrópica. Tendo em vista este panorama, o presente trabalho foi realizado com o objetivo de fornecer subsídios genéticos para a conservação da espécie ipê-roxo. Analisou-se 31 progênies de Tabebuia heptaphylla da região da Bacia do Médio Tiête. Utilizaram-se três locos, sendo um dos primers desenvolvido para o gênero Tabebuia e os outros para outros gêneros. O parâmetro Fst analisado mostrou haver uma menor diversidade entre progênies (21,47%) que dentro delas (78,53%). O coeficiente médio de endogamia, Fis, para a espécie, apresentou um valor relativamente alto (0,276) quando comparado com a literatura para espécies florestais. A taxa de cruzamento foi de 0,808, revelou que a espécie tem sistema reprodutivo misto, com tendência para a alogamia. As autofecundações foram de 19,2%, a percentagem de irmãos completos foi de 11,23%, de meios-irmãos foi igual a 69,57% e o coeficiente de coancestria ( xy) foi de 0,1776

Caracterização dos reservatórios do grupo Macaé no Campo de Garoupa - Bacia de Campos - por meio de interpretação sísmica e perfis de poço

The study area is the Garoupa Field, located 75 km from the coast of Rio de Janeiro in bathymetric elevation of 125 m and it is the first important offshore discovery of the Campos Basin with hydrocarbon production in the Albian carbonates. The high significance of carbonate rock reservoirs for the global oil industry and its degree of complexity, combined with the fact that the Garoupa Field is a mature field, make this research project interesting to develop a re-exploratory vision of the study area. The objective of this paper is to characterize the physical properties of the Macae Group reservoirs in the Garoupa Field through well correlation techniques, petrophysical analysis and seismic interpretation (3D), in order to evaluate qualitatively and quantitatively the response of geophysical data to the presence of carbonate rock reservoirs. From the analysis of well profiles (gamma ray, resistivity, density and sonic) it was possible to identify six reservoir levels in the Quissamã Formation. As a result, the reservoirs have good correlation between the wells in the Garoupa Field and show lateral facies variation. In the seismic interpretation, structural contour maps were generated in time (ms) from the top of the Macae Group and two horizons that correspond to the reservoir levels. These maps show that the oil producing area of this field is a structural high located at the west of the interpreted seismic cube, and it was classified as a rollover limited by lateral faults forming a horst. The seismic attribute maps show a good response to the reservoirs of the Garoupa Field because they are associated with amplitude anomalies, verified by the correlation between the physical properties of the reservoir rock and seismic data through cross plots, with emphasis in a linear correlation between the resistivity profile and the values of Maximum Absolute Amplitude and RMS Amplitude attributes

Grãos em carbonatos marinhos cretácicos da Bacia Potiguar: formações Ponta do Mel e Jandaíra

This work aims to identify and photograph grains that compose important Cretaceous carbonate units of the Potiguar Basin, represented by the Ponta do Mel and Jandaíra formations (Albian-Campanian). Petrographic investigation of thin sections was essential. The samples studied come from wells and surface samples from the collection UNESPetro – UNESP, Rio Claro. In the Ponta do Mel Formation, the grains consist of ooids, oncoids, peloids and bioclasts. Regarding to the identified bioclasts, the solenoporacean red algae, mollusks (bivalves and gastropods), echinoids, foraminifera, ostracods and worms were the dominant elements. In the Jandaíra Formation, the grains are composed by ooids, peloids and bioclasts, which are represented by green algae, mollusks (bivalves and gastropods), benthic foraminifera miliolids, worms, echinoderms and ostracods. The grains found in the Ponta do Mel Formation are somewhat similar to those found in the Jandaíra Formation, with the exception of calcareous algae. The subsurface material from the Ponta do Mel Formation is derived from the upper part of the unit, representing marine high-energy carbonates, which also contains ooids and Trocholina. The samples of Jandaíra Formation, collected in outcrops, often contain green algae, mollusks and miliolids, and come from inner shelf and lagoon facies previously described

Reconstrução paleogeográfica da área da bacia do rio Jequitaí - MG

Os solos, assim como as rochas, materiais inconsolidados e regolíticos, apresentam propriedades e características específicas, relativas a seus ambientes de formação. A partir de então o solo torna-se uma fonte de informação de toda a história evolutiva de uma região em seus mais variados parâmetros. Uma das formas de entender essa evolução dinâmica da paisagem é gerando um modelo de paleosuperfícies a partir da interpolação de confluências de drenagem. O trabalho objetivou reconstruir a paleogeografia da área inserida na bacia do Rio Jequitaí, a partir do Método de Isobases Confluentes, procurando analisar e identificar a evolução dos solos. A área está localizada na região centro-norte de Minas Gerais, sendo o Rio Jequitaí um afluente do Alto Rio São Francisco. O trabalho consistiu, na primeira etapa, em levantamento biblio/cartográfico da área em estudo. Durante esse levantamento, além de detectar as características físicas, bióticas e sócio-econômicas de modo a completar, reorganizar e adequar as informações da área, foi levantado um banco de dados base para a geração das Isobases, o qual foi constituído por modelos digitais de elevação (DEM) do programa ASTER e de dados vetoriais da principal rede de drenagem da bacia do Jequitaí. Na segunda etapa, as paleosuperfícies foram geradas usando aplicativos do programa ArcGis da ESRI. O produto final são as proto-superfícies para cada ordem de confluência. Assim no término do trabalho tem-se uma reconstrução da paleopaisagem correspondente, bem como das pro-estruturas equivalentes às condições de equilíbrio dinâmico daquele momento. A partir dos resultados obtidos foi possível concluir que a metodologia das Isobases Confluentes permite correlacionar os dados palinológicos, geocronológicos e geomorfológicos obtidos durante o estudo, para a reconstrução dos ambientes...
