  • Odour Control at Pesticide Facilities: Eliminating volatile compounds

    Chemical formulation plants are susceptible to emissions of unpleasant and malodorous volatile compounds, a fact which makes the implementation of efficient odour control measures essential. North-western Spain is home to one of the country's oldest industrial sites for the manufacture of phytosanitary products, with some facilities located relatively close to populated areas. Recently, the ...

  • Determination of P-Y Curves Using Inclinometer Data

    Derivation of p-y curves from lateral load tests on deep foundations is a tedious and expensive task, requiring large numbers of strain gages along the length of the pile to develop bending moment versus depth relationships. A method is proposed which allows derivation of p-y curves from simple inclinometer data using a least-squares regression technique. Inclinometer measurements can and have ...

  • El nuevo marco normativo en materia de suelos contaminados y el sector inmobiliario

    Uno de los problemas ambientales que más preocupan en la actualidad y que afecta directamente, entre otros agentes, a los sectores industrial e inmobiliario, es el reconocimiento de la gravedad de la contaminación de suelos y aguas subterráneas. Aparte de los costes que el saneamiento de estos terrenos puede conllevar y que en muchas ocasiones puede hacer inviable un proyecto de promoción ...

  • Synthesis, activity and thermal stability of gold nanoparticle on modified nh4-y type zeolite for cooxidation

    Carbon monoxide (CO) is a gaseous pollutant which enters the atmosphere from four major sources: fossil fuel combustion and industrial emissions, biomass burning, oxidation of CH4, and oxidation of hydrocarbons. The presence of CO causes problems to human health, particularly in cases of locally high concentrations, and affects the oxidizing capacity of the troposphere. Automobile emissions are ...

  • Spectral nodal method for numerically solving two-energy group X,Y geometry neutron diffusion eigenvalue problems

    We describe in this paper the recent advances in spectral nodal methods applied to diffusion problems in Cartesian geometry for neutron multiplying systems. In particular, we present a constant spectral nodal method for two-energy group X,Y geometry applied to neutron diffusion eigenvalue problems. We consider an arbitrary rectangular spatial grid defined on a two-dimensional rectangular domain ...
