Discharge-calcium concentration relationships in streams of the Amazon and Cerrado of Brazil: soil or land use controlled
(SPRINGER, 2011)
Stream discharge-concentration relationships are indicators of terrestrial ecosystem function. Throughout the Amazon and Cerrado regions of Brazil rapid changes in land use and land cover may be altering these hydrochemical ...
Recuperação da água de concentrado salino de eletrodiálise reversa por cristalização visando seu reuso na indústria
(Universidade Federal de Minas GeraisUFMG, 2015-03-27)
The decrease of water availability in the last years has motivated researchers to investigate alternative ways to reduce water consumption and improve reuse of water in many industries. The main objective of this work was ...
Determination of leachate toxicity through acute toxicity using Daphnia pulex and anaerobic toxicity assays
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2017-01-01)
The municipal solid waste (MSW) of large cities, in particular in developing countries, is mainly disposed of in landfills (LFs), whose inadequate management generates the emission of greenhouse gases and the production ...
Intra and interannual variability in the Madeira River water chemistry and sediment load
(SPRINGER, 2011)
Concentrations of cations (Na(+), Ca(2+), Mg(2+), K(+), NH(4) (+)), anions (HCO(3) (-), Cl(-), NO(3) (-), SO(4) (2-), PO(4) (3-)) and suspended sediments in the Madeira River water were determined near the city of Porto ...
Experimental cardio-depressant effects of clonixin
(1989)
1. The cardiovascular effects of CLX were studied. 2. CLX induced hypotension, bradycardia, negative chronotropism and negative inotropism. 3. Electrophysiological studies showed a decrease of sinus venosus discharge ...
Estudo da ruptura dielétrica durante a anodização de zircônio e o seu efeito sobre o processo de dopagem anódica de ZrO2
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2012-05-09)
In this work the fundamental aspects of electrolytic breakdown in ZrO2 films were investigated. The electrolytic breakdown is a type of dielectric breakdown that occurs during galvanostatic growth of anodic oxides. To ...
