1. Growth and yield of soybean cultivated in agroforestry systems
ABSTRACT Agriculture has caused numerous concerns regarding the preservation of natural resources. In this context, agroforestry systems are emerging as a more sustainable alternative. The present study aimed to evaluate growth characteristics, radiation use efficiency, biomass partition, and yield of soybean grown in two agroforestry systems and full sun. A

2. Agroforestry systems and understory harvest management: the impact on growth and productivity of dual-purpose wheat
Abstract: The objective of the study was to evaluate the growth and production efficiency of forage-grain dual-purpose wheat in two arrangements and four agroforestry systems (Intercrop-I and Intercrop-II), as well as to evaluate crop management for the wheat crops in two planting seasons (Crop Season I-2014 and Crop Season II-2015. The experiment was condu

3. Use of hydrogeophysical data to determine the role of faults in the geometry of the Barreiras Aquifer, Brazil
Abstract Characterizing the geometry of an aquifer is fundamental for determining the locations of more productive wells. Commonly, flow and hydraulic parameters, such as transmissivity, are related to the thickness of the aquifer, which emphasizes the importance of regional hydrogeophysical characterization. Shuttle radar imagery, well profiles and geoelect

4. Dynamics of solar radiation and soybean yield in agroforestry systems
Abstract Soybean (Glycine max L.) monocropping have had a great socio-economic and environmental impact on the world and agroforestry systems has been considered an alternative for more sustainable production. The aim of this study was to evaluate the effect of different arrangements of agroforestry systems of the species E. urophylla x E. grandis and P. dub

5. Transmissivity of Aquifer by Capture Zone Method: An Application in the Sete Lagoas Karst Aquifer, MG, Brazil
ABSTRACT Transmissivity is an important hydraulic parameter to determine the amount of water passed horizontally across a given saturated thickness of an aquifer. The techniques to quantify this parameter, such as grain size analyses or pumping tests, can have limitations of time/spatial scale, viability, or economically. One technique that can be used, but

7. ESTIMATIVA DE PARÂMETROS HIDRODINÂMICOS DE AQUÍFEROS EM ÁREAS DE EMBASAMENTO ATRAVÉS DE MÉTODOS INDIRETOS / ESTIMATIVA DE PARÂMETROS HIDRODINÂMICOS DE AQUÍFEROS EM ÁREAS DE EMBASAMENTO ATRAVÉS DE MÉTODOS INDIRETOS
The recession represents the period when the rivers flow is maintained predominately by subterranean water return, so establishing the base flux. In hydrographic basins, the recession coefficient (or of drain) can be determined in an indirect manner by several graph methods using series of hydrologic data. From this coefficient is possible to calculate other

8. Analysis microclimatic of mangroves in Barra of river Ribeira-Iguape / SP / Análise microclimática dos manguezais da Barra do Ribeira-Iguape/SP
The mangrove is defined as a coastal ecosystem of transition between terrestrial and marine environments and is characterized by salinized environment and the constant flooding caused by tides. With emphasis in the area of coastal systems Cananéia - Iguape, its importance is more related to the production of biomass, inserted in the natural bioenergy system

9. Propriedades termo-eletrônicas da molécula do DNA
This thesis presents a comprehensive and up-to-date account of some physical properties of the DNA molecule, such as its thermodynamics (specific heat) and electronic (electronic transmissivity and localization factor, among others) aspects. The DNA molecule can be considered as a symbolic sequence of a four letter alphabet, namely guanine (G), adenine (A),

10. Estruturas de bandas e propriedades de simetria dos modos eletromagnéticos em um cristal fotônico unidimensional
We perform in this work, through the techniques of transfer matrix, an analytical study of the photonic band structure and the density of states of a one dimensional photonic crystal consisting of a super-lattice composed by two alternating layers of air and GaAs of thicknesses a and the b, respectively. We find photonic band gaps, as expected, and also null

11. Characterization and nanoestructural control of silican made by flame aerosol synthesis / Caracterização e controle nanoestrutural da silica para fotonica produzida pelo metodo de aerosol em chama
The nanostructured silica preform made by the flame aerosol method represents a strategical precursor for technological applications in photonics, such as special optical fibers and high optical transmissivity lenses for ultraviolet radiation. In order to attain such a properties, it becomes particularly important to control the nanostructured characteristic

12. The dynamics of groundwaters in the estuary of the River Itanhaem, the south coast of the State of São Paulo / A dinamica das aguas subterraneas no estuario do Rio Itanhaem, litoral sul do Estado de São Paulo
The present work studied the influence of the tide in the coastal aquifers by identifying hydrodynamic and chemical alterations in the aquifiers. The research was carried out in the Itanhaém river estuary in two localities: in the Sitio de Pesquisa with 7 installed wells situated on the banks of the Acima river, 3,5 km from the ocean, and in the CePeRio - C
