Water erosion under simulated rainfall in different soil management systems during soybean growth
(2007) [Artigo de periódico]O manejo do solo influencia a cobertura superficial pelo resíduo cultural e, juntamente com a cobertura do solo pela copa das plantas, afeta a erosao hídrica. O objetivo do estudo foi quantificar as perdas de água e solo ... -
Water-food-energy nexus tradeoffs in the São Marcos river basin
(2021) [Artigo de periódico]Given its potentialities and characteristics, energy generation, food production, and water availability have a strong interdependency and correlation. Water is needed to produce energy and food, while energy is required ... -
Water hyacinth composting as a waste management strategy : a systematic review
(2022) [Artigo de periódico]Macrophytes proliferation problem is worldwide know resulting in impacts on natural environment, human health and economic activities. These organisms have several parameters resilience, which ensures high rate of reproduction ... -
“Water immersed inverted pendulum” : a physiomechanical model of shallow water walking at different depths and speeds
(2021) [Dissertação]During walking, the human body operates a mechanical energy exchange as an inverted pendulum. At each stride, there is an exchange between the forward kinetic energy and the gravitational potential energy of the center of ... -
Water in soybean oil microemulsions as medium for electrochemical measurements
(2003) [Artigo de periódico]Microemulsões de água em óleo de soja (w/o ME) foram preparadas com dodecil sulfato de sódio (SDS) como surfactante e com os álcoois amílico ou isoamílico, como co-surfactantes. A composição 40,0% de óleo, 43,2% de álcool, ... -
Waterlike anomalies in a two-dimensional core-softened potential
(2018) [Artigo de periódico]We investigate the structural, thermodynamic, and dynamic behavior of a two-dimensional (2D) core-corona system using Langevin dynamics simulations. The particles are modeled by employing a core-softened potential which ... -
Waterlike hierarchy of anomalies in continuous spherical shouldered potential
(2008) [Artigo de periódico]We investigate by molecular dynamics simulations a continuous isotropic core-softened potential with attractive well in three dimensions, introduced by Franzese [J. Mol. Liq. 136, 267 (2007)], that displays liquid-liquid ... -
Water protector project for Payment for Ecosystem Services (PES) of Vera Cruz, RS: analysis of the motivations and perceptions of participating landowners
(2020) [Dissertação]As a result of the decrease in the quantity and quality of water and the difficulties to reduce its degradation in rural areas, government agencies and institutions have developed and implemented policies for Payment for ... -

Water quality assessment of the Sinos River, Southern Brazil
(2010) [Artigo de periódico]A Bacia Hidrográfica do Rio dos Sinos localizada a nordeste do Estado do Rio Grande do Sul, entre as coordenadas geográficas de 29° 20’ a 30°10’ de latitude Sul e de 50° 15’ a 51° 20’ de longitude Oeste. As províncias ... -
Water saturation stress in Mimosa scabrella seedlings
(2019) [Artigo de periódico]The stress caused by water saturation has negative consequences for plants. The search for species tolerant to flooded soils can make feasible the use of areas with these characteristics. The objective of this study was ... -
A water soluble 3-n-propyl-1-azonia-4-azabicyclo[2.2.2]octanechloride silsesquioxane grafted onto Al/SiO2 surface : chromium adsorption study
