The act of containing water is one of the most practiced by the civilizations along history, in the will to increase the offer of water to many uses. The raise of environmental worries surround many human activities has given a big attention to dams. Indeed, the environmental consequences about dams are proporcional to their size, what gives to the big dams a more detailed Project and a bigger political concerning that increases the built, estability and maintenance of them. Then, the projects of medium and small dams are weak, limitaded to handbooks, textbooks and empirical recommendations, while the constructions of small dams are growing everytime more. With that being said, the present work intends to analise the geological and geotechnical conditionants that can cause break of small earth dams by making a case study in the Jaguari Mirim Watershed, located in the city of São João da Boa Vista (SP), and can be used to encourage the concern with small dams. In the area of study were identificaded, from satellite images, 248 dams. The map of physiographical compartmentalization defined by Pilachevsky (2013) was used to define the locations in the study área that would have bigger risk to the break of dams. Then, 9 of this dams were analised in field research, using references made by Cerri, Reis e Giordano (2011) and the risk of the analised dams were defined. A study about this type of structure is highly necessary to avoid big damages. An analysis of the geological and geotechnical conditionants that can cause break of dams guides the project in a way to avoid adverse consequences, especially when integrated with locacional conditions observed in the place of the dam’s building

O Ensino de Ciência do Sistema Terra constitui o eixo articulador de um programa, que integra ações educacionais e de investigação, tendo por objetivo central o desenvolvimento e aplicação de propostas educacionais que incorporam princípios da complexidade. O programa articula as ações educacionais no âmbito de uma investigação-ação. As ações são realizadas em contextos de educação formal e envolvem comunidades escolares da rede pública do município de São José do Rio Preto (SP, Brasil). Os trabalhos e as ações consideram as diretrizes curriculares e as políticas educativas vigentes e seus resultados revelam-se na construção de materiais e práticas polidisciplinares, que exploram as conexões existentes entre as diferentes áreas do conhecimento para ensinar os conteúdos curriculares, em prol de uma educação científica mais efetiva e pertinente. Os resultados, até então obtidos, revelam alguns contributos das ações educacionais e de investigação do programa que, ao potenciar e incentivar o trabalho colaborativo, o diálogo multidisciplinar e a reflexão crítica, favorecem o desenvolvimento de uma percepção mais acurada do significado e alcance da educação científica para a formação do indivíduo e das sociedades.

Biodiversity is a result of millions of years of biological evolution, and is the component of the system which supports life on our planet. Besides the intrinsic value of each species, all of them as a whole, as well as of the interactions among the species, and their interaction with the physical and chemical environment, result in ecosystem services vital for supporting life on Earth. Because of that, the science of biodiversity is largely recognized as a priority area of scientific investigation both in developed and developing countries. In Brazil, the research on biodiversity can be divided in three parts: 1) discovery and characterization of biodiversity – including marine and human-altered landscapes – systematics and taxonomy; 2) understanding the functioning of ecosystems and environmental services, including in marine and human-altered landscapes; 3) bioprospecting of the chemical diversity of the Brazilian biota.

Always seeking the maximum profit under the reduced production time and lower number of failures, companies are increasingly evolving and going after continuous improvement in order to remain competitive in the market. Thus, increasingly there is investment in the management system Lean manufacturing. Lean system is very important, because through it, the maximum value is added in the final product. Being measured by the efficiency and reducing failures to zero. In the studied company, Lean manufacturing system came into effect through the kanban system for purchasing, control and distribution of bulk material used in the assembly of the final product, which are earth-moving machines. It is very important to check the great change made in the company with the implementation of kanban. All inventory management becomes visual, elements are arranged in an organized manner, with addresses in structures, calculated in special boxes and finally, assemblers have the guarantee of an item supply, with the distribution cars located on their assembly area. This study participates effectively assuring the supply. Avoiding any failure on the lack of material, non-compliance of delivery times to the customer and maintenance of over-stock or obsolete inventory, in which case both cause financial loss to the company

From the agri-food crisis of 2007/2008, we live an intensifying period in the global land rush. The land grabbing is analyzed as a process that occurs on a global scale, especially to countries in Africa and Latin America, the main targets of the current global competition for land, because beyond the earth have low prices and the legislation be flexible, low and ineffective supervision of the state (especially in the issue of environmental and labor laws), also have vast tracts of arable land, with fertile soils and high availability of water resources (the latter element has become relevant in that case analysis). In addressing the land foreignization in the XXI century it is necessary to speak about the issue of biofuels and bioenergy, since it is these that define the current phase of land foreignization in Brazil. In the 1970s occurred the first incentive to produce ethanol in the sugarcane cultivation, with the policy of the National Alcohol Program (PROALCOOL). From the 2000s this interest again sharpened up and foreign capital began to see in Brazil a great opportunity for a production facility and purchase of old agro-processing plants that were implanted in PROALCOOL period but who were disabled. This is the case of Umoe Bioenergy, Norwegian company that in 2006 started its production in the municipalities of Narandiba and Sandhurst, located in the Pontal do Paranapanema region that, in turn, is the region of São Paulo with larger agrarian conflicts, settlements land reform, land grabbing and high poverty rates...

This article discusses the Brazilian land problem related to property rights of rural land. After emphasizing the importance of land policies in order to define and distribute rural land properties rights, we show how in Brazil the institutions of rural land registering and cadastering as separated processes debilitates the property rights, making them vulnerable to the effective occupying actions. In order to illustrate it, in this article we analyze Data based in a Case Study of conflict and property rights distributions in an important farming and mining region of southern Para state, in Brazil.
