13. Desempenho mecÃnico do solo condicionado com lodo de esgoto calcinado / Mechanical performance of the soil conditioned with burned sewage sludge
Amongst the global problems that most rouse studies and solutions before the environment crisis arise the ones concerning the destination of waste and the sewage system. The sustainable development requires the creation of solutions aiming the reduction or the elimination of the impacts on the environment. The waste may become an Engineering solution. The ai

14. ADIÇÃO DE RESÍDUO DE ARGAMASSAS MISTAS NA PRODUÇÃO DE TIJOLOS MODULARES DE SOLO-CIMENTO / ADDITION OF THE MIXED WASTE OF MORTAR PRODUCTION OF BRICKS OF MODULAR SOIL-CEMENT
Studies that use alternative materials and techniques of construction have assumed a great importance and relevance in engineering in the current context of environmental preservation and use of residues. This research had as a general objective studying the technical feasibility of applying the cement residue and sand, originally from the civil construction

15. Modelagem e quantificaÃÃo da compactaÃÃo de latossolos cultivados com eucalipto / Pattern and quantification from compactation in the Latosols cultivated with eucalypt.
The harvest operations and wood transport involves intensive traffic of machines on the soil, which may traffic in a same line several times, or randomly. Besides the passes number, the wood load transported also may affect the soil compaction, when the applied pressures for the machines exceed its bearing support capacity, altering the place where the root

16. Efeito da umidade do solo e carga aplicada pela roda compactadora no ambiente solo-semente em sistema de plantio direto na cultura da soja / Effect of water content and load applied by the press wheel on the soil-seed environment in the soybean direct planting system
The soils physical conditioning around the seeds is important to the initial cultivation development and to assure an adequate plant population. An appropriate soil-seed contact is required to a rapid emergence and a good effectiveness of cultivation. The present work aimed to study the effects of the combination between the soil water contents of the soil a

17. Effects of soil preparation systems and Efficient Microorganisms (EM) on soil physical properties, and improvement of potato yield and quality / Efeito de sistemas de preparo de solo e do uso de microrganismos eficazes nas propriedades físicas do solo, produtividade e qualidade de batata
As propriedades físicas do solo são preponderantes para a qualidade e produtividade da cultura da batata. Assim, o objetivo do presente trabalho foi avaliar algumas propriedades físicas do solo e a produtividade e qualidade dos tubérculos de batata. O experimento foi instalado em áreas de produção de batata na Chapada Diamantina (BA), de abril a agost

18. Soil compactation on Producing Layers Through No-Tillage and Minimum Tillage Systems / CompactaÃÃo do solo nas camadas agricultÃveis nos sistemas de plantio direto e cultivo mÃnimo
The handling systems can affect physical qualities of agricultural soils as density and porosity, as well as the organic matter reserves distributed on agricultural layerâs profile. This trial aimed at evaluating the effect of no-tillage and minimum tillage systems: no-tillage system during four consecutive years (NT4); minimum tillage after four consecutiv

19. Compaction of a Oxisol under no- tillage and grain yield of wheat, soybean and maize / CompactaÃÃo de um latossolo vermelho escuro sob sistema plantio direto e rendimento de grÃos de trigo, soja e milho
Essa pesquisa foi estabelecida com o intuito de avaliar o efeito dos estados de compactaÃÃo dos atributos fÃsicos do solo como: densidade, macroporosidade, microporosidade, porosidade total e, tambÃm, a resistÃncia à penetraÃÃo do solo, velocidade de infiltraÃÃo, desenvolvimento das plantas e rendimento de grÃos das culturas de trigo, soja e milho

20. Recuperação de solo de area de emprestimo com lodo de esgoto
The effect of the sewage sludge mud was evaluated in the recovery of an underground degraded due to the retreat of thick layer of original soil (loan area) more than 30 years ago, for occasion of the construction of the Ilha Solteira Hydroelectric Power Plant. The area is located in the municipal district of Selvíria, MS State, having been used in the const

21. Diagnose of water use on irrigation of crops in hydrological basin of Jundiai-Mirim river / SP / Diagnostico do uso da agua na irrigação de culturas na bacia do Rio Jundiai-Mirim / SP
Recent researches demonstrate that the use of water for agriculture represents 60% of total consumption of freshwater in Brazil and that many irrigation systems do not have any control of the use of water for this activity. Also, it is estimated that 40% of the water applied in irrigation is misused by percolation and superficial drainage, what generates a g

22. Caracterização hidrológica de duas microbacias visando a identificação de indicadores hidrológicos para o monitoramento ambiental do manejo de florestas plantadas. / Hydrological characteristics of experimental catchments for the identification of hydrological indicators for the environmental monitoring of forest plantations.
The present work consisted of the hydrological characterization of two catchments aiming to identify hydrologic criteria and indicators that can contribute for the implementation of better management practices of Eucalyptus plantations, as well as the evaluation of possible impacts of these activities on catchment yield and quality. The experimental catchmen
