Soil decontamination by supercritical extraction

Some of the existing techniques for soil decontamination are reviewed, giving particularemphasis to supercritical extraction (SCE), an environmental friendly technique whose applications to thetreatment of effluents and soil remediation are only emerging now. The experimental apparatus andanalytical technique used in our laboratory to study the extraction of atrazine from contaminated soil bySCE with carbon dioxide is described

Automatic Upload of Professional Profiles Directly from Sources

Globalization of education and employment is a fact [1]. Also, according to one International Labor Organization report [2], 6% of the world's work force was without job in 2012. Finally, a high development of information and communications technology (ICT) until 2020 is possible [3]. Why, then, should we go on using the conventional, complex, irksome, bureaucratic process of gathering our CV from often remote Sources, and share it with remote Recruiters who often don’t trust on it? Alternatively, it should be possible to solely supply our national identification to an Interface, and get, through national platforms, or else, our CV, expeditiously, and directly from those Sources; and to use it to apply to the Recruiting Entities, or to use them in internet platforms (LinkedIn, #1 Naukri, Times Jobs, Monster India, EURES, EUROPASS, Guardian’s and so). We propose a methodology, and ICT system, to upgrade the CV’s delivery to an expeditious and cheaper process.info:eu-repo/semantics/publishedVersio

Digital Complex Correlator for a C-band Polarimetry survey

The international Galactic Emission Mapping project aims to map and characterize the polarization field of the Milky Way. In Portugal it will cartograph the C-band sky polarized emission of the Northern Hemisphere and provide templates for map calibration and foreground control of microwave space probes like ESA Planck Surveyor mission. The receiver system is equipped with a novel receiver with a full digital back-end using an Altera Field Programmable Gate Array, having a very favorable cost/performance relation. This new digital backend comprises a base-band complex cross-correlator outputting the four Stokes parameters of the incoming polarized radiation. In this document we describe the design and implementation of the complex correlator using COTS components and a processing FPGA, detailing the method applied in the several algorithm stages and suitable for large sky area surveys.Comment: 15 pages, 10 figures; submitted to Experimental Astronomy, Springe
