An experiment was implemented to study fluid flow in a pressure media. This procedure successfully combines nuclear magnetic resonance imaging with a pressure membrane chamber in order to visualize the non-wetting and ...

Liquid-phase nonpoint source pollution dispersion and removal on sustainable urban drainage systems (SUDS) is an important issue for urban pollution mitigation which remains a challenge, as current researches mostly focus ...

A flow-focusing device with circular cross-section to produce monodispersed air bubbles and foams in several gelatine solutions is presented. Four flow regimes were studied by varying the gas pressure: dripping, bi-disperse ...

Constructed wetlands (CW) have been widely used to treat different types of water, including acid mine drainage (AMD). However, little is known about their performance in the removal of As from AMD. In this study, a ...

From a hydrological perspective, is specially necessary to face the challenge of obtaining a complete spatial arrangement of the drainage network on floodplains with extremely flat relief, impermeable soils and exposed to ...

The very stable boundary layer occurs on nights with light wind and clear skies, which cause strong radiative cooling on the surface, changing the structure and some characteristics of the normal stable boundary layer. ...

An on-line scandium preconcentration and determination system implemented with inductively coupled plasma optical emission spectrometry associated with flow injection was studied. Trace amounts of scandium were preconcentrated ...

This work presents propositions of improvements for Avenue Unisinos, located in the district Cristo Rei, in the city of São Leopoldo / RS. In the geometry question, it is sought to give greater fluidity to the transit by ...
