13. Numerical combination for nonlinear analysis of structures coupled to layered soils
This paper presents an alternative coupling strategy between the Boundary Element Method (BEM) and the Finite Element Method (FEM) in order to create a computational code for the analysis of geometrical nonlinear 2D frames coupled to layered soils. The soil is modeled via BEM, considering multiple inclusions and internal load lines, through an alternative fo

14. Soil profile, relief features and their relation to structure and distribution of Brazilian Atlantic rain forest trees
In tropical forests, the environmental heterogeneity can provide niche partitioning at local scales and determine the diversity and plant species distribution. Thus, this study aimed to investigate the variations of tree species structure and distribution in response to relief and soil profile features in a portion of the largest remnant of Brazilian Atlanti

15. Prediction of stress-settlement curve on tropical sandy soils based on seismic cone test / Previsão da curva tensão-recalque em solos tropicais arenosos a partir de ensaios de cone sísmico
Apresenta-se neste trabalho a aplicação de um método para a previsão da curva tensão-recalque de fundações diretas assentes em solos tropicais arenosos a partir de resultados de ensaios de cone sísmico (SCPT). Os locais estudados foram os campos experimentais de fundações da EESC/USP - São Carlos e da UNESP-Bauru, onde existem resultados de provas

16. Desempenho de bananeiras irrigadas em resposta a diferentes profundidades efetivas do solo na Chapada do Apodi - CE / Performance of banana in response to different irrigation effective soil depth in the Apodi Plateau - CE
The production of banana can be affected whether plants are cropped in sites with physical impedances, as those found in shallow soils. The aim of this research was to verify if irrigated banana plants performance is affected by effective soil depth, and for this purpose were evaluated both soil physical and chemical attributes, as well as plants nutritional

17. Avaliação da aptidão agrícola de solos do projeto de Assentamento Alegria, município de Pium, Tocantins.
ABSTRACT: The Alegria Rural Settlement Plan is a result of Land Reform politics of the INCRA, located in the town of Pium, Tocantins, in order to use unproductive lands for rural settlement development. The soil of the Alegria PA is generally shallow or very shallow (Haplic Inceptisols, Quartzipsamments Entisols), with low fertility and degraded by the manag

18. Características estruturais, fitossociológicas e produtividade de um campo sobre basalto supercial / Phytosociological, structural and productivity characteristics of a native pasture on basaltic litolic soil
Few studies had adequately described the characteristics and productive capacity of natural grasslands associated to shallow basaltic soils in Pampa Biome. This study was carried out on natural pasture at Santana do Livramento municipality, in the Campanha region of Rio Grande do Sul, Brazil aiming to describe their floristic and structural diversity and to

20. Evaluation of the lisem model for the simulation of hydrosedimentologic processes in a small rural catchment on the basalt slopes of Rio Grande do Sul, Brazil / Avaliação do modelo LISEM na simulação dos processos hidrossedimentológicos de uma pequena bacia rural localizada nas encostas basálticas do Rio Grande do Sul
The intensive cultivation of the areas of southern Brazil that have poor agricultural potential (shallow soils on steep, basaltic hillsides) has contributed to the degradation of the environment by increasing rates of soil erosion and sediment yields. In this study, traditional monitoring methods have been combined with concurrent mathematical modeling to ve

21. Soil properties for different uses in irrigated perimeter of Sertão in Pernambuco State. / Atributos do solo em função dos diferentes usos em perímetro irrigado do Sertão de Pernambuco
The semiarid Northeast Brazil, represented by the Caatinga biome is characterized as an environment of low water availability and shallow soils, which require regional scientific community, further studies directed at understanding and managing these resources, for their preservation in a sustainable way. Thus, this study aims to evaluate the chemical, physi

In spite of the great importance of the soil organic matter for the sustainability of the natural systems and of agricultural production, its study remains incipient in the area of the Edge of the Rio Grande do Sul Plateau, where different research have been reporting negative aspects of the inadequate soil use. In that sense, the carbon distribution evaluat

23. Soil quality in native forest and pasture eco-systems in the eastern Acre region of Western Amazon / Qualidade do solo em ecossistemas de mata nativa e pastagens na região leste do Acre, Amazônia Ocidental
The state of Acre is presently at the initial stage of converting its forests into pastures. Around 12% of its total area (19.200 km2) has been deforested. Out of this, approximately 81% (13.352 km2) have been utilized by several productive segments in Acre (farmers, land settlers, extractivists, riverine farmers and cattle producers), with extensive pasture

24. Airborne geophysical and geological data applied to the selection of groudwater potential areas in crystalline rocks of Ceara, Brazil / Dados aerogeofisicos e geologicos aplicados a seleção de areas favoraveis para agua subterranea no dominio cristalino do Ceara, Brasil
The location of water well in Northeast Brazil is usually based on the interpretation of structural lineaments in aerial-photographs and electromagnetic and electrical resistivity ground geophysics surveys. However, the success of these techniques is variable, and the small coverage area is another limitation. This Thesis favors a different approach, the use
