NN-AirPol: a neural-networks-based method for air pollution evaluation and control
A method for air pollution evaluation and control, based on one of the most popular neural networks – the backpropagation algorithm, is proposed. After the backpropagation training, the neural network, based on weather ...
Urban Air Pollutants are Significant Risk Factors for Asthma and Pneumonia in Children: The Influence of Location on the Measurement of Pollutants
(EDICIONES DOYMA S ABARCELONA, 2012)
Background: Air pollution is associated with a substantial burden on human health; however, the most important pollutants may vary with location. Proper monitoring is necessary to determine the effect of these pollutants ...
Air pollution dispersion inside a street canyon of Göttinger Strasse (Hannover, Germany): New results of the analysis of full scale data
(Inderscience Enterprises, 2010-01)

Effects of ambient levels of air pollution generated by traffic on birth and placental weights in mice
(ELSEVIER SCIENCE INC, 2008)
Objective: To examine whether there is an association between fetal and/or placental weight and exposure to ambient levels of air pollution in mice. Design: Chronic experiments on mice that were exposed to polluted vs. ...
Variations in peak expiratory flow measurements associated to air pollution and allergic sensitization in children in Sao Paulo, Brazil
Background In the last 20 years, there has been an increase in the incidence of allergic respiratory diseases worldwide and exposure to air pollution has been discussed as one of the factors associated with this increase. ...
Association between household air pollution exposure and Chronic Obstructive Pulmonary Disease outcomes in 13 low- and middle-income country settings
(American Thoracic Society, 2018)
RATIONALE: Forty percent of households worldwide burn biomass fuels for energy, which may be the most important contributor to household air pollution. OBJECTIVES: To examine the association between household air pollution ...
