Effect of pH and nitrite concentration on nitrite oxidation rate

Jiménez Douglas, Emérita; Giménez García, Juan Bautista; Ruano García, María Victoria; FERRER, J.; Serralta Sevilla, Joaquín (Elsevier, 2011-07-29)

The effect of pH and nitrite concentration on the activity of the nitrite oxidizing bacteria (NOB) in an activated sludge reactor has been determined by means of laboratory batch experiments based on respirometric techniques. ...
Influence of Hydraulic Conductivity and Wellbore Design in the Fate and Transport of Nitrate in Multi-aquifer Systems

Mejía, Amanda; Cassiraga, Eduardo Fabián; Sahuquillo Herráiz, Andrés (Springer Verlag (Germany), 2012)

Nitrate concentrations in multi-aquifer systems are heavily affected by the presence of wellbores (active or abandoned) that are screened in several aquifers. The spatial variability of hydraulic conductivity in the confining ...
Influence of nutrient inputs from a wetland dominated by agriculture on the phytoplankton community in a shallow harbour at the Spanish Mediterranean coast

Sebastiá Frasquet, María Teresa; Rodilla Alamá, Miguel; Sanchís Blay, José Andrés; Altur Grau, Vicent Jesús; Gadea Pérez, María Isabel; Falco Giaccaglia, Silvia Laura (ELSEVIER SCIENCE BV, 2012)

[EN] The Safor Wetland (Western Mediterranean) is a protected ecosystem declared Site of Community Importance under the Habitats Directive. Agricultural practices have been part of this ecosystem throughout history, and ...
Modelling Temporal Changes of Nitrogen Dioxide Concentrations in an Urban Area

Capilla, Carmen (Witpress, 2012)

Meteorological variability must be taken into account in the modelling of temporal changes in air pollutants to evaluate emissions reduction strategies. In this paper nitrogen dioxide (NO 2) hourly data are analyzed at two ...
Monitoring and forecasting nitrate concentration in the groundwater using statistical process control and time series analysis: a case study

García-Díaz, J. Carlos (Springer Verlag, 2011-03)

Contaminated water resources have important implications on health and the environment. Nitrate contamination of the groundwater is a serious problem in the European Union. A method based on the statistical process control ...
New sources of resistance to PepMV in tomato

Soler Aleixandre, Salvador; López Del Rincón, Carmelo; Prohens Tomás, Jaime; Nuez Viñals, Fernando (Eugen Ulmer, 2011-10)

Pepino mosaic virus (PepMV) disease causes important losses in tomato (Solanum lycopersicum) yield around the world. In order to find new sources of resistance to this virus, a collection of accessions from different ...
Secondary organic aerosol formation from the photo-oxidation of benzene

Borrás García, Esther Mª; Tortajada Genaro, Luis Antonio (Elsevier, 2012-02)

The production of condensate compounds from the degradation of benzene by OH radical chemistry was studied. Secondary organic aerosol (SOA) formation was investigated in the EUPHORE (European Photoreactor) simulation ...
