3. Estudo da correlação entre resistência mecânica e velocidade ultrassônica para um material terroso
This dissertation presents the studies carried out on the applicability of ultrasound as a non-destructive evaluation method of the structural conditions of earth structures designed to building rammed earth. To this purpose the ultrasound was defined as a proposal for utilization of a non-destructive method on the evaluation of the relation of earthy materi

4. Compactação do solo e desenvolvimento de couve-brócolo sob diferentes intensidades de tráfego de tratores
Intensive and mechanised agriculture took care of the necessities of the increasing world-wide demand for agricultural products, and at the same time, was the cause of negative effect in the fertility in the soil, the preservation of the natural resources and in the development and productivity of plants. This work compared the levels of compacting in the so

5. Análise de curvas de retenção e distribuição de poros de um latossolo vermelho distrofico submetido aos sistemas de plantio convencional e direto
Para avaliar os impactos ambientais gerados pelos sistemas de plantio, é necessário avaliar as variações provocadas por eles na estrutura do solo. O espaço poroso é o melhor indicador da qualidade estrutural do solo, pois é responsável, dentre muitos fatores, por fenômenos de transporte de água e solutos em seu interior e retenção de água por el

6. Compacting of the ground under agricultural traffic / CompactaÃÃo do solo sob trÃfego agrÃcola
A compactaÃÃo do solo tem sido apontada como um dos grandes problemas da agricultura moderna. No Brasil e no mundo existe grande preocupaÃÃo com o aumento das Ãreas agrÃcolas mecanizadas que apresentam problemas de compactaÃÃo. Este estudo foi realizado no NÃcleo Experimental de Engenharia AgrÃcola da Universidade Estadual do Oeste do Paranà - UNI

7. INFLUÊNCIA DAS CARACTERÍSTICAS FÍSICAS DO SOLO NAS PERDAS DE ÁGUA POR ESCOAMENTO SUPERFICIAL NO SUL DO BRASIL E URUGUAI / SOILS PHYSICAL CHARACTERISTICTS INFLUENCES IN THE RUNOFF IN SOUTH OF BRAZIL AND URUGUAY
The objective of this work was to modeling runoff in soils with different physical characteristics, with three simulated rainfall intensities (30, 60 and 120 mm h-1) in Rio Grande do Sul and Uruguay. For simulated rainfall was used a portable rainfall simulator of multiple nozzles. Six plots were delimited by metal sheet borders (0,5 m2), with a runoff colle

8. Estudo comparativo dos ensaios de CBR e Mini-CBR para solos de UberlÃndia-MG / Comparative study of tests of CBR and Mini-CBR for soils of UberlÃndia - MG
This present work shows a comparative study between the tests of CBR and the tests of Mini-CBR to the soils of UberlÃndia - MG, aiming at to extend the use of the Mini-CBR, in view of its advantages in relation to the CBR. The main advantages of the test of Mini-CBR are more practical, demands a smaller amount of samples, it has a faster execution procedure

9. Influence of either operational speed and the pressure applied on compress wheels in the initial establishment of the maize crop under no-till system / Influência da velocidade operacional e da carga aplicada pelas rodas compactadoras sobre o estabelecimento inicial da cultura do milho em sistema de plantio direto
Since Brazil is one of the main maize producers throughout the world, this crop becomes an important target for research. To obtain the successful implantation of the crop, a good soil-seed contact should be promoted, besides to be careful about the good distribution of the plantlets. The no-till planting minimizes the undesirable effects from the preparatio

10. ContribuiÃÃo ao Estudo da ImprimaÃÃo Betuminosa das Bases RodoviÃrias do Estado do Cearà / CONTRIBUTION TO THE STUDY OF BITUMINOUS PRIME COAT ON ROADÂS BASE LAYERS OF CEARà STATE
Bituminous prime coat can be defined as the application of an asphalt film layer on a granular base, for the improvement of its technological qualities. In pavements subjected to the role of the prime coats is even more important due to the reduced thickness of the surface and its low or inexistent structural function. The purpose os this work is to investig

11. Projeto, ConstruÃÃo e ValidaÃÃo de um Sistema de CompressÃo Uniaxial para Estimativa da CompactaÃÃo do Solo
The compaction of the agricultural soils has worldwide importance because of the increasing of the farm with machinery resulting in the increasing of heavy machines for cultivation system, mainly, in the developed countries. The term, soils compaction refers to the compression carried out on the non-saturated soil, during which an increase of bulk density ex

12. Aplicação de geoprocessamento para o aumento da eficiência de percurso em operações agrícolas na cultura da cana-de-açúcar (Saccharum spp.). / Aplication of geoprocessing for increase the way eficient on the agricultural machines operations on the sugar cane (Saccharum spp.) crop.
The use of machines and agricultural implements in cultures annual or semi-perennial in Brazil is one of the factors that more demands financial resources, due to the cost in fuels, labor and machinery depreciation. Besides, if badly used, can happen environmental damages, such as erosion and compacting soil. Precision Agriculture is growing in Brazil and it
