(2002-12-29)The atmospheric processes prior to and during the outbreak of 2 galernas (July 25, 1995 and May 30, 1996) are analyzed. Data from surface stations, meteorological satellites, the Punta Galea wind profiler radar and numerical ... -
Analysis of multivariate stochastic signals sampled by on-line particle analyzers: Application to the quantitative assessment of occupational exposure to NOAA in multisource industrial scenarios (MSIS)
(IOP Publishing, 2015)In multisource industrial scenarios (MSIS) coexist NOAA generating activities with other productive sources of airborne particles, such as parallel processes of manufacturing or electrical and diesel machinery. A distinctive ... -
Analysis of summer O3 in the Madrid air basin with the LOTOS-EUROS chemical transport model
(Copernicus, 2019-11)Tropospheric O-3 remains a major air-quality issue in the Mediterranean region. The combination of large anthropogenic emissions of precursors, transboundary contributions, a warm and dry aestival climate, and topographical ... -
Analysis of the effect of temperature reaction time on yields, compositions and oil quality in 3 catalytic and non-catalytic lignin solvolysis in a formic acid/water media using experimental design.
(Elsevier, 2017-03-01)[EN] The catalytic solvolysis of Norway spruce (Picea abies L.) lignin in a formic acid/water media was explored at different temperatures and reaction times (283–397 °C and 21–700 min, respectively). Non-catalyzed experiments ... -
Antioxidant, Antifungal and Phytochemical Investigations of Capparis spinosa L.
(MDPI, 2021-10-19)The antioxidant and antifungal activities of crude hydro-ethanolic extract from Capparis spinosa L. (Capparidaceae) leaves and their fractions, obtained by liquid-liquid extraction (LLE) using solvents with increasing ... -
Application des huiles essentielles dans le domaine des embalages alimentaires.
(2020-02-29)The overall objective of this work was to study the suitability of Poly Lactic Acid (PLA) and starch containing natural agents, as active packaging. For this, we chose several natural actives substances such as essential ... -
Application of a Combined Adsorption−Ozonation Process for Phenolic Wastewater Treatment in a Continuous Fixed-Bed Reactor
(MDPI, 2021-08-22)This work studied the removal of phenol from industrial effluents through catalytic ozonation in the presence of granular activated carbon in a continuous fixed-bed reactor. Phenol was chosen as model pollutant because of ... -
