The long-term interactions of aromatic amines with soils are important in defining the fate and transport of these compounds in the environment. Abiotic loss of aniline from the aqueous phase to the soil phase occurs with ...

The applicability of a distributed parameter model for describing the distribution of aniline and α-naphthylamine between soil and aqueous phases at short contact times was assessed. Mass action equations considered in the ...

Release profiles of p,p′-DDT, p,p′-DDD, and p,p′-DDE from sediment collected from Indian Creek, Alabama, were measured with a gas purge-induced desorption technique and compared to a model developed in this work. DDT entered ...

Ambient Intelligent are usually emerged in contexts like health, education, business and so on. However there are not many researches focusing on social aspects as public administrations. In these kinds of contexts, some ...

A novel ring resonator configuration with Bragg gratings is presented. The stability of this configuration is studied by a z-transform technique. A router design with a FWHM of 17 MHz, a -40-dB rejection ratio, and a 15-dB ...

In 1949 the world bank sent 14 international advisers to Colombia. These expert in foreign exchange, transportation, industry, agriculture, and others represented the first mission of its kind to attack "underdevelopment" ...

A novel reconfigurable fibre based tuneable filter is proposed. The module relies on a cascaded connection of Mach-Zehnders and an amplified fibre ring resonator. MHz range adjustable FHWM bandwidths and high crosstalk are ...

En esta memoria se reflejan los aspectos más relevantes de los programas de la Universidad Especializada de las Américas, sobre todo aquellas acciones realizadas en las unidades académicas, de investigación , extensión, ...
