Use of the HDS system (hydric depuration with soils) associated to other constructed wetlands techniques for public water supply
Two projects of water treatment for public water supply were developed and operated by using combined systems of constructed wetlands. One of the projects was carried out in the town of Analandia, Sao Paulo, Brazil and ...
An hydrochemical answer to a legislative demand involving health risk related to water quality
Effluents and surface waters around an area involved with the inking of tissues at Itatiba municipality, São Paulo State, Brazil, were chemically analyzed with the purpose of evaluating the influence on the water quality ...
Nano-based surface treatm effects on swelling, water sorption and hardness of wood
(Universidad del Bío-Bío, 2011)
Elemental composition of surface waters in the Antarctic Peninsula and interactions with the environment
(KLUWER ACADEMIC PUBL, 2003-09)
The fast changes in chemical and biological properties of many coastal and inland waters in the last decades reflect the pressure of man on the environment. The surface waters of the Antarctic Peninsula, located far from ...
Evolution equation for short surface waves on water of finite depth
(Elsevier B.V., 2009-08-15)
We address the question of determining the evolution equation for surface waves propagating in water whose depth is much larger than the typical wavelength of the surface disturbance. We avoid making the usual approximation ...
Surface pressure-area isotherms for Langmuir monolayers and a docking molecular orientation of perylene tetracarboxylic derivatives on a water surface
(Spectroscopy Soc Canada, Ottawa, 2004-01-01)
The surface pressure-molecular area (pi-A) isotherms for Langmuir monolayers of four perylenetetracarboxylic (PTCD) derivatives, measured with varying subphase temperatures and compression speeds, are reported. The behavior ...
Aging of plasma-activated copper and gold surfaces and its hydrophilic recovery after water immersion
(Elsevier B.V., 2014-01-01)
A significant increase of surface hydrophilicity of copper and gold surfaces was obtained after atmospheric pressure plasma treatment using the surface dielectric barrier discharge with specific electrode geometry, the ...
Detection of Giardia and Cryptosporidium cysts/oocysts in watersheds and drinking water sources in Brazil urban areas
The protozoan parasites Giardia and Cryptosporidium have been described as important waterbone disease pathogens, and are associated with severe gastrointestinal illnesses. The objective of this paper was to investigate ...
