Avaliação de NO2 na atmosfera de ambientes externos e internos na cidade de Araraquara, São Paulo
(Sociedade Brasileira de Química, 2009-01-01)
The seasonal behavior of NO2 concentration shows a maximum occurring during sugarcane crop and this suggests that the biomass burning is significant source of emission at this time of the year. Along the day, the variation ...
Absorption Kinetics of Sulfur Dioxide in Flint Corn during Steeping
(Elsevier Science, 2001-08)
A mathematical model was proposed to simulate simultaneous sulfur dioxide absorption and reaction during corn steeping. The parameters of the model, the diffusion coefficient and the reaction rate constant, were determined. ...

Colorimetric determination of sulfur dioxide in air using a droplet collector of malachite green solution
(Academic Press Inc., 1999-06-01)
The measurement of sulfur dioxide in air at the parts-per-billion level is described. The experimental arrangement consists of two optical fibers placed on opposite sides of a liquid droplet of malachite green solution. ...

Soil Physical Properties, Carbon dioxide Emissions and Their Relationships under Different Management Systems in Semi-arid Region of Eastern Tunisia
(2021-01-01)
In agricultural systems, soil carbon dioxide emissions and physical properties are thought to depend largely on management practices. This field study was carried out in a semi-arid region of eastern Tunisia to evaluate ...
