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

A criação e os esforços para manter os periódicos das associações profissionais e científicas foram fundamentais para consolidar o processo de formação da cultura técnica moderna no Brasil, a partir da segunda metade do século XIX. Ainda limitadas às dificuldades de circulação e a um reduzido corpo técnico, essas publicações configurariam uma arena pública que incorporou debates nacionais articulados desde então: necessidade de conhecimento e de integração do território, políticas centrais de circulação e comunicação, entre outros. Nesse contexto, a Revista da Sociedade de Geografia do Rio de Janeiro empenhava-se em desvelar um Brasil pouco conhecido. Compreender o papel desse periódico na construção de um pensamento próprio sobre a região Nordeste constitui o objetivo deste trabalho. A análise documental se faz a partir do material publicado entre 1885, ano da sua criação, e 1932, quando divulga artigo emblemático sobre o tema. Os estudos sobre os índices pluviométricos irregulares, a descrição da paisagem física e as crônicas de viagem à região proporcionaram novo olhar cujos contornos aprofundam a discussão acerca da conformação da “dimensão técnica das secas” e permitem o entendimento da formulação dos projetos nacionais (de transformação e controle do território) no âmbito técnico-científico, na virada para o século XX.

Este trabalho visa o ensino da Geografia, que se constitui em uma preocupação recorrente para os professores que buscam contribuir para uma educação de qualidade, comprometida com a formação de novos cidadãos, visto a importância de se estudar a natureza (relevo, solo, vegetação, hidrografia) abordando de forma integrada, a discussão ambiental, atividades produtivas, econômicas e sociais. A busca por práticas inovadoras que permita ao professor, estimular a participação ativa do aluno no processo de aprendizagem e a descoberta do conhecimento dentro das orientações metodológicas de um ensino diferenciado foi o motivo para utilizar maquetes interativas como recurso didático. Assim pretende-se contribuir na compressão e interpretação de conteúdos geográficos auxiliando o aluno no seu desenvolvimento perceptivo, estimulando a capacidade de observar, pensar, interpretar a realidade física e humana da Terra. Elaborou-se também um caderno de apoio explicativo e instruções para a confecção da maquete interativa, servindo de apoio em aulas práticas. O trabalho com maquetes serve como um recurso didático interessante que proporciona ao aluno, dependendo do seu desenvolvimento cognitivo, dominar conceitos espaciais e as representações em diversas escalas. Proporcionando desta forma melhor entendimento dos fenômenos geográficos através do estudo integrado entre as diferentes formas de relevo e a relação com os elementos do sistema ambiental, sua evolução e a transformação da paisagem de forma prática e construtiva.

The goals of this study are to identify the potencialities avaiable in elementary public schools for the development of an educational process wich includes environmental issues helpping to find its integration with university in order to contribuite raises teaching levels for a better comprehension of regional environmental problems. Research data were collected through questionnaires and interviews with geography teachers analyising theirs activities and perspectives on the environmental crisis and environmental education. The study also offers sugestions for the devellopment of interdisciplinaires programs trying to contibute for the construction of citizenship showing the importance of better comprehension from environmental problems which includes physical, economics, social, political and cultural aspects.

Tomato postharvest losses are very high in Brazil and the goal of this research was to evaluate the effect of handling and the transport of tomato fruits, cultivar Romana on the steps of harvesting, weight and transportation to the packinghouse, pointing some critical points. Tomatoes were harvested at plastic boxes, weighted and shipped to a packinghouse. Fruits taken directly from the plant were determined as reference. The parameters evaluated were weight loss and mechanical injury and tomato physical quality after storage during 21 days. It was observed an increasing on the weight loss, external damage, and postharvest losses, after storage. Handling and transportation were the cause of an increase in 6.6% in external damage and 1.93% of weight loss after storage, when comparing harvested fruits and fruits evaluated on the packing-house. The main reason for postharvest losses was due to mechanical injury caused during transportation mainly due to the compressure force among fruits and against the plastic boxes.

Rice husk, employed as an energy source at milling industries in Brazil generates, after burning, a dark ash. This residue is not yet conveniently disposed, being currently dumped on large areas, causing environmental problems. This research intended to evaluate the applications of residual rice husk ashes (RHA) as a partial replacement of cement for mortar production. Rice husk ash was chemically characterized through X-ray fluorescence, determination of carbon content, X-ray diffraction, and laser granulometric analysis. Mortar specimens were submitted to two different exposure conditions: internal and external environments at a maximum period of five months. Physical-mechanical testing were compressive strength and ultrasonic pulse velocity (UPV). Although presenting good mechanical performance, the mortar based on ash (RHA) did not present pozolanicity but it can be employed in cement matrices as inert material (filler).

This work indicates presuppositions for the qualitative research in Physical Education, starting with a literature review based on the cultural frame of reference. Firstly, we introduce the debate concerning the natural and the human sciences and implications for the Physical Education; we then use a cultural axis as a ground basis for the research in the area, proposing the 'dense description' as a possibility for knowledge building; finally, we bring up examples of studies conducted with such an approach. This theoretical methodological approach allows the study of the human being as a cultural being, thus opposed to the naturalised view of a human - predominant in Physical Education.

Our aim was to verify the influence of a physical activities proposal in the quality of life and self image of incontinent women. This study was comparative and exploratory and was developed in 16 weeks. Thirty-seven women with and without urinary incontinence (IU) participated in the study. After the study, significant improvement in general health perception (p < 0.001), UI impact (p = 0.035), physical limitations (p = 0.015), personal relations, (p = 0.048), sleep and disposition (p = 0.012) and concerned with the gravity measurements (p = 0.011) was observed. Concerning self image, alterations in appearance were not observed; however, concerning body satisfaction, the women felt less satisfied with their bodies (p = 0.007). There was a reduction in the number of regions where they felt pain (p = 0.0003) and that they did not like (p = 0.0017). In conclusion, the Physical Education professionals using a systematized and integrated physical activities program can lead the women with IU to significant improvement in the perception of their quality of life and health concerning their self image with improvement of the IU symptoms and reduction of frequency and amount of urinary loss.
