O presente trabalho teve como objetivo, mapear o uso da terra das sub-bacias dos córregos São José e Água do Ventura no ano 2000, e verificar, como esta ocupação vem atuando nos processos de assoreamento dos corpos de água. O estudo teve como base, um mosaico em escala nominal aproximada de 1:10.000, produzido a partir de fotografias aéreas verticais do ano 2000, em escala nominal aproximada 1:30.000. Os resultados permitiram constatar que a pastagem foi a maior ocupação do solo, com 430,89 ha, correspondente a 65,21% da área estudada. Devido ao manejo inadequado do solo, é a cobertura vegetal que mais produz sedimentos por ocasião das chuvas, merecendo cuidados especiais para evitar os processos erosivos do solo. Foi constatado também, que os serviços de adequação e melhoria de estradas rurais, executados nas estradas municipais BRU-030 (antiga Bauru/Piratininga) e variante da BRU-030, atingiram seus objetivos, pois, praticamente, acabaram com a erosão das estradas, permitindo tráfego o ano inteiro, reduzindo o custo de manutenção das estradas e aumentando o abastecimento do lençol freático, além de outros benefícios.

There is little research on the practices of sanitary inspection in the chain of production of vegetables to the consumer, especially those eaten raw, they are liable to serve microorganism such as bacteria, fungi and parasites, contributing to possible health hazards. The aim of this study was to assess qualitatively contamination by parasites and / or commensals of medical interest in lettuce leaves (Lactuca sativa) fresh market in the municipality of Quata Sao Paulo. A total of 15 random samples were analyzed every other day of the three different places that sell vegetables a grocery store, a supermarket and a vegetable garden during the month of May 2011. The parasites and / or commensals found in lettuce were Entamoeba coli (67%), Entamoeba histolytica (20%), Giardia sp (13%) and Ascaris lumbricoides (7%). The analysis showed the presence of parasites and / or commensals in all samples, except in the cultivated garden which showed poor sanitary conditions, probably due to contamination in the shipping and handling by third parties in supermarket and grocery store. The parasite monitoring sanitary conditions of vegetables sold in urban environments becomes relevant for preventive measures to avoid the continued parasitic cycle and possible future health complications.

This work presents the results obtained in analyzes of aggregates from construction and demolition waste produced by the plant of the City of Guaratinguetá. Using this data and comparing with the specifications of NBR 15115, it was found that the materials do not possess the requisite minimum characteristics to be utilized as a basis for low-pavement traffic. In order to identify the main reasons of the material does not fit in the standard, we used the data obtained in a study conducted by Professor. Dr. Luiz Eduardo de Oliveira at the plant of the company AB Environmental Solutions Ltd., located in Pindamonhangaba. With different characteristics, the aggregates from construction and demolition waste produced by this plant showed the possibility of using pavements. The use of these residues in paving reduces the impact on the environment caused by construction.

This work is resulted of studies about the urban circulation in the modern cities. It was developed from two case studies: the city of São Paulo, specifically Santo Amaro's neighborhood and the city of Regensburg in Germany. The urban circulation of these places was analyzed starting from the premise that the daily of the inhabitants is a relevant factor to be considered. It was researched the types of transportation, the accessibility, and the clearance of public transportations. One of the main purposes of this work was to present general guidelines for the improvement urban circulation in the modern cities, as well as to supply didactic material that contribute to the reflection about urban circulation focusing priorly on the problems of traffic of driving force vehicles

La circulation urbaine dans les villes brésiliennes a été marquée par l'influence directe de l'automobile. Grâce aux possibilités découlant de l'automobile, les villes se développent de plus en plus désordonnées et exigent la création de nouveaux moyens pour maintenir le flux du trafic. Cependant, la création de nouvelles routes est venu de collaborer avec les embouteillages, parce que plus les routes ont été construites, plus elles ont généré le besoin de transport. La question du développement durable a commencé à être traités de 1987 et alors, les premières idées pour résoudre, entre autres, le problème de la circulation urbaine. Une des solutions suggérées par les études est l'utilisation de transports non-motorisés. Ainsi, le vélo est devenu le grand pari pour un transport plus durable. Au Brésil, le vélo est largement utilisé, mais n'est pas considéré comme un réel moyen de transport, qui conduit à de mauvais investissements et incitations. Par conséquent, des mesures sont nécessaires pour encourager le transport à vélo pour se obtenir, avec d'autres mesures, un transport plus durable. Enfin, l'étude de cas dans deux villes, Guaratinguetá et Lorena, montre l'influence de l'automobile dans la formation de ces deux villes, qui a fini par nuire les autres modes de transport qui auraient pu être mieux utilisés

Sabe-se que na atualidade, é grande a preocupação da comunidade científica mundial, em relação à resistência microbiana frente às substâncias convencionais, utilizadas indiscriminadamente, por isso, é crescente a motivação da pesquisa básica na bioprospecção de novas substâncias, que apresentem atividade antimicrobiana e antifúngica e que possam ser uma alternativa segura e eficaz contra esses microorganismos no tratamento das doenças causadas por eles. As dermatofitoses, por exemplo, são processos infecciosos de pele, pêlo e unhas que acometem muitas pessoas, de todas as faixas etárias, no mundo todo, provocando as chamadas tinhas ou tineas, denominadas corporis, pedis, cruris, capitis, unguium(onicomicose) e outras (dependendo o local do corpo onde estão), causadas pelo dermatófito filamentoso, Trichophyton rubrum. Estudos envolvendo este patógeno são cada vez mais importantes, devido ao aparecimento de linhagens resistentes aos medicamentos antifúngicos disponíveis no mercado, e ao comportamento invasivo deste agente em pacientes com o sistema imune comprometido. Porém, somente a descoberta de novas drogas não é suficiente, é preciso desenvolver produtos eficazes e seguros, que possam veicular essas substâncias sem causar prejuízo ao paciente. Sendo assim, a proposta desse trabalho é desenvolver uma emulsão A/O, contendo óleo essencial de Melaleuca alternifolia (TTO), verificar sua estabilidade preliminar e caracterizá-la realizando o estudo reológico da formulação, determinar a concentração inibitória mínima (CIM) e a concentração fungicida mínima (CFM) do TTO e averiguar a atividade antifúngica in vitro da emulsão frente ao T. rubrum, agente patogênico ao qual se destina o uso do produto

In this work was developed a program capable of performing automatic counting of vehicles on roads. The problem of counting vehicles is using expensive techniques for its realization, techniques which often involve manual counting or degradation of the pavement. The main motivation for this work was the importance that the vehicle counting represents to the Traffic Engineer, being essential to analyze the performance of the roads, allowing to measure the need for installation of traffic lights, roundabouts, access ways, among other means capable of ensuring a continuous flow and safe for vehicles. The main objective of this work was to apply a statistical segmentation technique recently developed, based on a nonparametric linear regression model, to solve the segmentation problem of the program counter. The development program was based on the creation of three major modules, one for the segmentation, another for the tracking and another for the recognition. For the development of the segmentation module, it was applied a statistical technique combined with the segmentation by background difference, in order to optimize the process. The tracking module was developed based on the use of Kalman filters and application of simple concepts of analytical geometry. To develop the recognition module, it was used Fourier descriptors and a neural network multilayer perceptron, trained by backpropagation. Besides the development of the modules, it was also developed a control logic capable of performing the interconnection among the modules, mainly based on a data structure called state. The analysis of the results was applied to the program counter and its component modules, and the individual analysis served as a means to establish the par ameter values of techniques used. The find result was positive, since the statistical segmentation technique proved to be very useful and the developed program was able to count the vehicles belonging to the three goal..
