Geofísica aplicada no diagnóstico preliminar do antigo lixão do município de Rio Claro - SP

The issue of solid waste disposal and urban growth are conflictive, since the areas where old uncontrolled refuse disposal were away from the city today are incorporated to the urban area population. Thus, now population is closer to the degradation of contaminants coming from waste disposal, and, in some cases, these areas become housing subdivisions. This work aims to support the diagnosis of a former landfill in the municipality of Rio Claro (SP), using geophysical methods through resistivity anomalies. In order to develop the diagnostic, it was utilized water and soil analysis of a preliminary report and techniques of vertical electrical sounding and electrical profiling. The areas influenced by the garbage presented less resistivity than the one of the natural subsoil. Through the interpretation of results, the local potentiometric map was elaborated, as well as a map of calculated resistivity. The interpretation of these products indicated a disagreement between the groundwater flow and the current topography, leading to an identification of a preferential direction of the contamination plume in the NE-SW. These observations prove the applicability of geoelectrical methods in areas of former waste disposal with little information.

Uma Nova Abordagem do Ciclo Reprodutivo dos Machos e Fêmeas, e da Origem e Desenvolvimento dos Oócitos dos Ostariophysi e Perciformes Neotropicais Aplicada a Representantes da Série Otophysi, Gymnotus sp. (Gymnotidae), Hoplias Malabaricus (Erythrinidae), Sorubim Lima (Pimelodidae) e Tanichthys Albonubes (Cyprinidae), e dos Perciformes, Cichla Temensis (Cichlidae)

Nos peixes, durante a vida reprodutiva o desenvolvimento gonadal é cíclico e anual. As alterações estruturais das gônadas de machos e fêmeas provêm parâmetros úteis para a sua classificação macroscópica e microscópica. Porém, o desenvolvimento das células germinativas, nem sempre é consoante com os diferentes tipos de classificação e, machos e fêmeas nem sempre parecem concatenados. Neste estudo, aplicando-se propostas recentes, utilizadas primariamente para peixes derivados, notadamente os Perciformes marinhos, e tomando como modelo experimental representantes da série Otophysi, Hoplias malabaricus (Characiformes), Tanichthys albonubes (Cypriniformes), Sorubim lima (Siluriformes) e Gymnotus sp. (Gymnotiformes), e dos Perciformes Neotropicais, Cichla temensis, foram descritos, comparativamente, os eventos iniciais da oogênese e da espermatogênese, assim como o desenvolvimento oocitário a fim de traçar um paralelo entre grupos basais e derivados. A partir dos resultados, verificou-se que a maioria dos eventos morfológicos durante o desenvolvimento oocitário é similar entre grupos basais e derivados. Os Perciformes de água doce divergem dos grupos basais por duas características: a presença de inclusões lipídicas, que surgem no citoplasma perinuclear após o início da formação dos alvéolos corticais e deposição de vitelo e por uma tênue proteólise do vitelo durante a maturação final. A foliculogênese e espermatogênese não apresentam divergências e parecem ser processos conservados entre os Teleostei. Durante a fase de Regeneração, os eventos iniciais desses processos em fêmeas e machos, respectivamente, são responsáveis por altos índices de proliferação das células germinativas, quando comparado às demais fases. Além disso, analisou-se ...(Resumo completo, clicar acesso eletrônico abaixo)

Carta geológico-geotécnica aplicada ao planejamento urbano da região do Córrego Bertini, município de Americana - SP

This paper focuses on the implementation of a geological and geotechnical mapping to the planning of the region stream Bertini, territorial expansion area of the municipality of Americana (SP), a medium-sized city in the countryside of Sao Paulo state, with great potential for growth industrial and residential. To this end, based on the methodology established by the Institute for Technological Research, the charters geological and geotechnical aimed at exposing the capabilities and limitations of the soil. The analysis of similar soil characteristics such as geology, geomorphology, slope, geotechnical testing and the current use and land cover was possible to recognize four geotechinical units. The units I and III are related to areas of top and concave and convex parts of the study area, shown to be sites of low occupancy restriction. However the units II and IV, respectively allocated in the floodplain of the Piracicaba River and the banks of the stream Bertini and some of its drainage, showed a more restricted area due to proximity to water bodies and drainages that offer higher slopes.

Uma nova abordagem do ciclo reprodutivo dos machos e fêmeas, e da origem e desenvolvimento dos oócitos do Ostariophysi, e Perciformes neotropicais aplicada ao Anostomidae, Schizodon nasutus e ao Sciaenidae, Plagioscion squamosissimus

Nos peixes, durante a vida reprodutiva o desenvolvimento gonadal é cíclico e anual. As gônadas passam por alterações de forma, de tamanho, de cor e de textura que são utilizadas como parâmetros para a sua classificação macroscópica. Porém, o desenvolvimento das células germinativas, nem sempre é consoante com essa classificação e, machos e fêmeas nem sempre parecem concatenados. Novas propostas de classificação vêm surgindo na tentativa de compatibilizar as informações macroscópicas e histológicas, considerando a atividade do epitélio germinativo de machos e fêmeas. Ocorre, no entanto, que essas propostas vêm sendo desenvolvidas em estudos com Perciformes marinhos. Aqui, tomando-se como modelo o Characiformes, Schizodon nasutus e o Perciformes, Plagioscion squamosissimus analisou-se comparativamente o ciclo reprodutivo de ambas as espécies, frente às classificações tradicionais e às novas propostas de classificação adicionadas das características histológicas das gônadas, e pode-se perceber que a análise macroscópica das gônadas, muitas vezes, não corresponde a sua verdadeira fase do ciclo reprodutivo, analisado microscopicamente. Isso se dá porque muitas das características cruciais para distinção das fases não são visíveis a olho nu, como folículos atrésicos, maturação do oócito ou anastomose de túbulos ou lóbulos testiculares. Assim, para determinação das fases reprodutivas, deve-se sempre contar com a análise microscópica e, no presente estudo, foi considerado que a melhor classificação para tal é a proposta de Brown-Peterson e colaboradores (2009), que divide o ciclo reprodutivo em seis fases reprodutivas, bastante detalhadas. A partir da descrição do ciclo reprodutivo feminino e masculino em S. nasutus e P. squamosissimus, os dados foram correlacionados com o índice gonadossomático, determinando, assim, que o período...

Análise comparativa de concepções de cartografia geomorfológica aplicada a ambientes litorâneos

The intense urbanization in coastal environments can cause environmental changes due to the susceptibility of these areas. It is therefore of utmost importance to understand the environmental quality of coastal area and the geomorphological features are essential to make it possible, as well as the geomorphological maps that are used as an instrument to analyze the relief. However, there is no standardization among the geomorphological mapping techniques, since the proposals vary according to the taxonomy of the relief, the adopted scale and the objective of the researcher. This paper aims to carry out geomorphological mappings of sectors of the city of Mongaguá, in São Paulo state, according to the conceptions of Verstappen and Zuidam (1975) and Gustavsson, Kolstrup and Seijmonsbergen (2006), seeking to verify the possibilities and constraints that each one can provide for environmental management. Verstappen and Zuidam’s design (1975) is a classical international bibliography proposal indicating the symbols and colors that will be used to represent the relief according to the origin shape of the geomorphological features; Gustavsson, Kolstrup and Seijmonsbergen's conception (2006) is a latest international proposal which also uses symbols and colors that can be combined to represent various forms of relief, coming from different origins. The mappings in this research are although not presented as a mainstream map, but as a cartographic representation in which the symbols are superimposed on the digital ortophoto map to provide the reader an association between symbolism and the relief represented. The result is a comparative analysis among the symbols that were used in each mapping, in which is discussed what design is the most appropriate, considering the adopted scale and the geomorphological features of the mapped area

Proposta de elaboração de carta de sensibilidade ambiental aplicada a postos de combustíveis em Rio Claro-SP

Leaking of hydrocarbon in fuel underground storage tanks constitute object of concern for urban environmental management, because therefore they provoke damages to the physical, biological and socioeconomic environment. Though laws that regulate this essential activity exist, aiming at to prevent contamination with hydrocarbon, we observe that this still happens. This fact evidences that the selection of places for installation of gas stations has not considered the characteristics of the natural environment, implying in more critical consequences associated to the leaking. The objective of this work is to elaborate a chart applied to the gas stations in Rio Claro/SP. The determination of the Index of Environmental Sensitivity for elaboration of such chart was carried through breaking the selection of factors of Environmental Sensitivity of physical, biological and socioeconomic environment. The balance of these factors was given by means of Ad hoc consultation. The crossing of the information was carried through using the method of overlapping of overlays. The result is a chart that shows us areas with classes of high, middle and low Environmental Sensitivity. One gives credit that this type of material can be used as criterion in the selection of adjusted areas for installations of new gas stations and management of the already installed gas stations. The diagnosis of the current situation of the gas stations in the area and recommendations had also been elaborated.

Modelagem matemática aplicada a precificação de opções

The mathematical models are critical to determine theoretical prices of options and analyze whether they are overrated or underrated. This information strongly influence in operations carried out by the investor. Therefore, it is necessary that the employee model present high degree of reliability and be consistent with the reality of investment to which it is intended. In this sense, this dissertation aims to apply the steps of mathematical modeling in the Pricing of options for decision making in the investment of a hydroelectric power plant. Was used a Monte Carlo simulation, with the Latin Hypercube Method, to determine the volatility of returns of the project. In order to validate the proposed model, compared to the results found by the Binomial Model, which is one of the models most used in this type of investment. The results reinforce the hypothesis that the mathematical modeling with the Binomial Model is critical to investment decision-making in hydroelectric power
