1. Water balance in soil covered by regenerating rainforest in the Paraíba Valley region, São Paulo, Brazil
Resumo Objetivou-se avaliar o balanço hídrico em Latossolo Vermelho-Amarelo coberto por floresta tropical em regeneração há 30 anos, na bacia do rio Una entre abril de 2016 e março de 2017. Os valores da capacidade de campo (FC) e ponto de murcha permanente (PWP) usados para calcular a capacidade de água disponível (AWC) no solo foi determinado pela

2. Glyphosate commercial formulation effects on preoptic area and hypothalamus of Cardinal Neon Paracheirodon axelrodi (Characiformes: Characidae)
ABSTRACT In Colombia the use of glyphosate commercial formulations (Roundup™) for spraying have left deleterious effects on animals and humans. Much of this spraying takes place at the Orinoco basin, habitat of one of the most exported ornamental fish in Colombia, Cardinal neon. To evaluate the effect of Roundup Activo™ four experimental treatments were

3. Stock assessment of the peacock bass Cichla temensis (Humboldt, 1821), an important fishing resource from the middle Negro river, Amazonas, Brazil
Resumo O tucunaré Cichla temensis é uma importante espécie de peixe da bacia Amazônica, uma vez que esta espécie é simultaneamente explotada pela pesca comercial e de subsistência. Além disso, é preferida pelos pescadores esportivos que atuam na região do rio Negro, o segundo maior afluente do rio Amazonas. Foram usados dados de pescarias experimen

4. CH4 and CO2 monitoring in the air of underground coal mines in southern Brazil and GHG emission estimation
Abstract This study aims to assess methane (CH4) and carbon dioxide (CO2) concentrations in the ventilation systems of two coal mines (A and B) in the Santa Catarina coal deposit in southern Brazil (Paraná Basin, Bonito Formation), and estimate their greenhouse gas (GHG) emissions. The highest CH4 levels (1.8%) were recorded in strong methane emanation area

5. Modeling of Soil Losses on a Yellow Argisol Under Planted Forest
ABSTRACT Erosion prediction models are a useful tool for soil use planning and soil conservation. This study aimed to apply the Universal Soil Loss Equation (USLE) in an experimental sub-basin located in the municipality of Teixeira de Freitas, in the southern end of the state of Bahia, Brazil. The following variables were calculated: rainfall erosivity fac

6. COMPARISON OF METHODS FOR ESTIMATING REFERENCE EVAPOTRANSPIRATION: AN APPROACH TO THE MANAGEMENT OF WATER RESOURCES WITHIN AN EXPERIMENTAL BASIN IN THE BRAZILIAN CERRADO
ABSTRACT This study aimed to compare methods for estimating reference evapotranspiration using an experimental basin in the Brazilian Cerrado, for water management purposes. For that, we estimated daily reference evapotranspiration over a certain period (time series between 1982 and 2012) through different empirical methods. These methods consisted of Blaney

7. SMART MONITORING AND DECISION MAKING FOR REGULATING ANNULUS BOTTOM HOLE PRESSURE WHILE DRILLING OIL WELLS
Abstract Real time measurements and development of sensor technology are research issues associated with robustness and safety during oil well drilling operations, making feasible the diagnosis of problems and the development of a regulatory strategy. The major objective of this paper is to use an experimental plant and also field data, collected from a basi

8. Experimental investigation of the enhanced oil recovery process using a polymeric solution
Enhanced oil recovery methods are becoming an important source of oil production of wells that have already been explored and, by these methods, of increase of the total volume of oil extracted. An important example is the injection of polymeric solutions after the injected water has reached the breakthrough point. In the present work an experimental apparat

9. Effects of flooding and shading on growth and gas exchange of Vochysia divergens Pohl (Vochysiaceae) of invasive species in the Brazilian Pantanal
Vochysia divergens Pohl (commonly known as cambara) is a pioneer tree species that is native to the Amazon Basin but has been invading the seasonally flooded wetlands of the Brazilian Pantanal, forming monospecific communities. The physiological aspects associated with cambara invasion, including the effects of flooding and shading on growth and leaf gas exc

10. Bacias de dissipação por ressalto hidráulico com baixo número de Froude : análise das pressões junto ao fundo da estrutura
Atualmente, está se tornando cada vez mais usual, na engenharia brasileira e internacional, aproveitamentos hidroelétricos com baixa queda e elevada vazão específica, resultando em um escoamento na entrada do dissipador de energia hidráulica com baixos números de Froude (Fr1). Os aproveitamentos da UHE Santo Antonio, da UHE Jirau e da AHE Belo Monte pe

11. Social and reproductive physiology and behavior of the Neotropical cichlid fish Cichlasoma dimerus under laboratory conditions
In this work we describe for the first time the social and reproductive behavior of the Neotropical fish Cichlasoma dimerus (Heckel, 1840) [Perciformes: Cichlidae], endemic to the Paraná River basin, using a comprehensive-integral approach, including morphological and physiological features. This substrate breeding fish has biparental care of the fry and pr

12. Estudo do processo sedimentológico na bacia experimental do Ribeirão Concórdia-SC / Study of sedimentological process in the Ribeirão Concórdia experimental basin
O movimento de solutos e material particulado das vertentes das bacias em direção aos corpos de águas superficiais, produz uma interação entre os atributos físicos e químicos dos solos e a qualidade dos sedimentos encontrados em rios, lagos e reservatórios, afetando diretamente a qualidade dos mesmos. Na bacia do ribeirão de Concórdia, situada no m
