13. Albedo of an Amazon tropical rainforest: field measurements, remote sensing, modeling, and its influence on the regional climate / Albedo de uma floresta tropical Amazônica: medições de campo, sensoriamento remoto, modelagem, e sua influência no clima regional
Albedo is defined as a ratio between reflected solar radiation and incoming solar radiation over a surface. It is a main factor that affects the terrestrial radiation balance and has been frequently considered in the global and regional climate studies. Amazon is one of planets regions where the response of regional atmospheric circulation is more intense. S

14. CaracterizaÃÃo do processo de salinizaÃÃo do aqÃÃfero Marituba no bairro do Mutange, Lagoa Mundaà - Maceià - Alagoas
The Marituba aquifer belongs to the Barreiras / Marituba system and is located inside of Alagoas Sedimentary Basin, in Alagoasâ coastal region. Since the 1970âs, aquifers play an important role in urban and industrial water supply to the city of MaceiÃ, involving mainly wells from the Bebedouro and MutangeÂs group. MaceiÃÂs demand for water has been in

15. Análise por métodos hidrológicos e hidroquímicos de fatores condicionantes do potencial hídrico de bacias hidrográficas - Estudo de casos no Quadrilátero Ferrífero (MG)
As surface water and groundwater are continuously interacting, any external influence is able to affect them in the long or short term. Because of this interconnection, aquifer information can be obtained by the analysis of drainage flow pattern (hydrological approach). This approach is based on the analysis of baseflow recession, i.e., the study of the aqui

16. Desenvolvimento de mudas de cafeeiro produzidas em tubetes, sob malhas termo-refletoras e malha negra. / Development of coffee seedlings produced in plastic tubes, under termo-reflective and black screens.
This experiment evaluated, in greenhouse conditions, the development of coffee seedlings produced in plastic tubes, under the effect of screens used for shading. The treatments were black screen 50%, known commercially as "sombrite" or as "black screen", considered standard for the development of these seedlings, and thermo-reflective screens with four diffe

18. Modelling lucerne (Medicago sativa L.) crop response to light regimes in an agroforestry system
The general goal of this research was to understand the agronomic and physiological changes of a lucerne crop in distinct physical radiation environments and to verify the potential of lucerne to grow under shaded conditions. To achieve this, the research was conducted in four main steps: (i) firstly, experimental data collection in the field using two artif

19. Floristic and structure of tree species under several physiographic conditions in a seasonal semidedicuous florest fragment in Minas Gerais, Brazil / Composição florística e estrutura de vegetação arbórea em fragmento de floresta estacional semidecidual secundária, na Zona da Mata de Minas Gerais
The remnant forests in the Southeastern Brazil are highly fragmented and degraded. To maintain or increase its biodiversity, management plans should be based on the understanding of the floristic and the structure of tree species and its environmental conditions. The present study was carried out in a hilly region, in Paula Cândido county (20522 latitude So

20. Caracterização microclimática, ecofisiológica e fitossociológica em uma floresta estacional semidecidual secundária, em Viçosa, MG / Microclimatic, ecophysiological and phytosociological characterization of a secondary semideciduous seasonal forest, in Viçosa, MG, Brazil
A study in the domain of the Atlantic Forest was carried out in ten sites with different slope, aspect and topographic position at the Estação Experimental Mata do Paraíso, in Viçosa, Minas Gerais State, Brazil (20o45 Latitude South, 42o55 Longitude West and an average altitude of 690 m). The spatial and temporal characterization of the photosyntheticall

21. A novel fiber-optic photometer for in situ stability assessment of concentrated oil-in-water emulsions
The purpose of this research was to evaluate a novel fiberoptic photometer for its ability to monitor physical instabilities occurring in concentrated emulsions during storage. For this, the fiber-optic photometer was used to measure transmission of oil-in-water emulsions stabilized with hypromellose (HPMC) as a function of oil volume fraction and droplet si

22. Two Bacteria Phylotypes Are Predominant in the Suiyo Seamount Hydrothermal Plume
Microbial diversity and populations in a hydrothermal plume that was present inside the caldera of the Suiyo Seamount, a submarine volcano on the Izu-Bonin Arc, were investigated by performing a phylogenetic analysis of the 16S rRNA gene and by using fluorescence in situ hybridization (FISH). Corresponding to transmissivity, an indicator of turbidity, the ve
