Identificação de áreas de risco na região urbana do município de Guaratinguetá, SP, quanto à ocorrência de inundações e processos erosivos

The city of Guaratinguetá, SP, presents in its history, several instances of property damage and human losses, conditional on the event of flooding and mass movement of soil, resulting from the development of erosion processes. The extent and severity of these events that affect humans and their properties is the result of the illegal occupation of these areas as potential geohazard. Thus, it is of great importance to physical characterization and identification of such areas within the map of the same city as a way to minimize the effects and mitigate the consequences of these events. Thus, this graduate report presents a series of field campaigns, geotechnical laboratory testing, consultation with maps and satellite images, representative of the physical environment, and the city plan as a means conclusive for the delimitation of risk areas with potential for occurrence of erosion and / or flooding on the map representing the urban area of Guaratinguetá, SP. Also featured are the descriptions of the main characteristics of those areas identified as being at risk, along with proposals to avoid or minimize the impact of problems related to flooding and erosion processes on the local population

As transformações do espaço geográfico e sua relação com os processos erosivos de uma área do noroeste de Regente Feijó/SP

O presente trabalho discute a relação sociedade e natureza a partir do estudo de caso dos processos erosivos identificados em um recorte espacial, localizado no Noroeste do município de Regente Feijó/SP. As dinâmicas socioeconômicas que se processaram no Oeste Paulista e, consequentemente, no município de Regente Feijó, ao longo das décadas de ocupação, são evidências das lógicas de apropriação ancoradas em pressupostos de exploração massiva dos recursos naturais, tendo em vista a produção de gêneros agrícolas valorizados no mercado internacional, tais como o café, o algodão e a cana-de-açúcar. Além disso, a pecuária também se constituiu como importante base econômica regional e, somada aos demais usos agrícolas, contribuiu para o depauperamento dos solos, o assoreamento dos cursos d’água e o surgimento de erosões (laminares e lineares) nas áreas rurais e urbanas. Neste sentido, além da discussão envolvendo os problemas desencadeados pelo agravamento dos processos erosivos aos pequenos produtores rurais e aos moradores do Distrito de Espigão, é evidenciada a importância das práticas conservacionistas como forma de contingenciamento de tais fenômenos

A utilização de modelos matemáticos para a otimização de processos

This dissertation has as main theme the discuss about how the use of mathematical models for process optimization. The current scenario of strong competition to conquer the consumer market necessitates the development of improvements to better performance of the process as a whole, is to reduce costs, increase efficiency or effectiveness. Thus, the use of methodologies to assist in this process is becoming increasingly viable. Methodologies developed in the past are being studied and improved. An example is the Desirability, the object of the present study, which was developed in the 80's and has been improved over time. To understand and study this methodology was applied to the desirability function in three instances, where it was used Design of Experiments (DOE), taken from scientific papers, using the Solver tool (Excel ®) and desirability (Minitab ®). Thus, in addition to studying the methodology, it was possible to compare the performance of tools used for optimization in different situations. From the results of this study, it was possible to validate the superiority of one of the models studied compared fairly

Construtivismo e métodos tradicionais: uma análise dos processos de alfabetização atuais

The constructivist methodology of literacy has been adopted in many schools, however, there are many criticism regarding the way teacher are devising the way how to teach children. To reflect on this aspect this research were carried out theoretical studies about the subject, as well as observations and reflections about the current process of literacy in Brazilian schools. Thus, in this research, the constructivist methodology of literacy was analyzed from its bases, in order to observe if the teachers are actually accomplishing their practice according to this “theory”, as well as the difficulties encountered by students on this methodology. Also was analyzed the methodology syllabic literacy, to be able to make a mapping of the positive aspects and the limitations presented by this method, in this way being able to reflect about adequacy of the analyzed methods of a better learning process of written language by children. This research aims to show that more important than the stark choice between a literacy method and the another is the commitment of the literacy teacher with the students who want to alphabetize, noting that the teacher should used, sometimes several methods to get the largest number of literate children in the classroom, emphasizing the work with good texts, so that children feel the taste and enjoyment of reading in their daily lives
