Extração de amônio de filtros de amostragem, coleta e determinação pelo método da gota suspensa
(Editora Unesp, 2000-01-01)
A amostragem de amônia no ar é feita usualmente com filtro impregnado com ácido. O ácido ascórbico, quando usado como impregnante, é facilmente oxidado em meio básico e aquoso, gerando uma solução fortemente colorida que ...
Water quality in six sequentially disposed fishponds with continuous water flow
(2010-01-27)
This study evaluated selected limnological variables in inlet water in six sequentially distributed semi-intensive fishponds. Data were collected during 15 consecutive days in three distinct grow-out periods (May, October ...

Self‐consistent reaction field calculations on the proton transfer in ammonia‐formic acid systems as a model for hydrogen bonding in amino acids in solution
(1988)
The reaction field (RF) model of solvent effects, implemented within the SCF‐CNDO/2 scheme of calculation, has been applied to analyze the proton transfer in the NH3…HCOOH system in the presence of several polarizable ...
Environmental factors associated with heterotrophic nitrogen-fixing bacteria in water, sediment, and riparian soil of Suquía River
(Elsevier Gmbh, 2014-07)
In this study we investigated the environmental factors associated with biological nitrogen (N) fixation (BNF) in water, sediments, and riparian soil along a polluted river (Suquía River of Córdoba, Argentina). Here, we ...
Exploring the Catalytic Mechanism of Human Glutamine Synthetase by Computer Simulations
(American Chemical Society, 2016-10)
Glutamine synthetase is an important enzyme that catalyzes the ATP-dependent formation of glutamine from glutamate and ammonia. In mammals, it plays a key role in preventing excitotoxicity in the brain and detoxifying ...
