Emprego do método eletromagnético (em) na investigação e mapeamento de contaminações geradas por cemitérios: o caso de Monte Alto/SP

The use of geophysical methods in the analysis and mapping of likely contamination plumes has shown a huge value in the development of researches related to environmental issues. Among the main geophysical methods applied to this purpose, the geoelectrical methods stand out, being based on the use of electric and electromagnetic fields. The electromagnetic method (EM) uses physical environment responses created by electromagnetic field propagation, consisting of an alternated electric output and a magnetization force, used to obtain the electric conductivity (σ) of the subsurface materials. It has a broad application in the mineral exploration and prospection, and its use has been also efficient in environmental researches. By the electromagnetic method, this work examined and mapped possible contaminations created by cemetery leachate in the Saudade's Cemetery, located in the city of Monte Alto, Sao Paulo, where sedimentary rocks of the Bauru Group are exposed. Cemetery leachate is a putrefactive liquid, generated from the decomposition of organic matter, which contains substances that can contaminate soil and groundwater. Results achieved in this work show that the use of the electromagnetic method is an important indirect tool in the investigation of environmental contaminations in areas with highly contrasting physical properties

Espacialização do uso da terra da microbacia do Córrego Monte Belo - Botucatu (SP), obtido por imagem de satélite de 2011 e fotografias aéreas coloridas de 2000

O presente trabalho teve como objetivo avaliar as variações de uso e ocupação do solo entre os cenários de 2000 e 2011 da microbacia do córrego Monte Belo – Botucatu (SP). Para tanto, utilizou-se de geotecnologias, sendo a integração de informações realizada no Sistema de Informações Geográficas (SIG) - IDRISI, aliada ao uso de cartas digitais do IBGE, escala 1:50.000, além de fotografias aéreas (2000) e imagens de satélite LANDSAT - 5 (2011). Através dos dados obtidos, foram detectadas três classes de uso do solo sendo que em 2000, elas correspondem ao reflorestamento, pastagem e mata ciliar e em 2011, reflorestamento, mata ciliar e solo exposto. Desta forma, pode-se concluir que as ferramentas de análise baseadas em SIGs trazem a possibilidade de analisar as variações no espaço e no tempo além de resultar em informações que podem subsidiar o planejamento da microbacia do Córrego Monte Belo.

Aplicação da Simulação de Monte Carlo no estudo de testes de fadiga em rodas agrícolas

Due to the increasing demand from clients and the search for better performances in the heavy vehicles industry, a progressive evolution in technology in a general way was needed. This paper uses a scientific method to validate, prior to its manufacture, the project of an agricultural wheel for sugar cane harvesters. Monte Carlo Simulation is used in conjunction with Finite Elements Method, in order to simulate the wheel's behavior in a cornering test, identify possible failure regions and get an estimate for its life under fatigue. To this end, test conditions according to EUWA Standards were simulated and obeyed, relevant to fatigue. Simulation results were interesting, according to industry experts involved in the project and manufacture of the product in question, and have provided important elements for the decision making regarding improvements that could be made on the product project before its execution
