Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Journal of Supercritical Fluids, 55 (2011). http://dx.doi.org/10.1016/j.supflu.2010.09.030Rosmarinus officinalis (rosemary) extracts were obtained in a supercritical pilot-scale plant. Based on experimental information available in the literature for analytical or low-scale processes, extraction temperature and pressure were selected to be 313 K and 30 MPa. At these extraction conditions, the kinetic behavior of the pilot-scale overall
extraction curve were determined with respect to yield, antioxidant activity and carnosic
acid content. The overall extraction curve was represented using Sovova’s model; the
average deviation between measured and calculated yields was lower than 2%. Mass
transfer coefficients in the fluid and solid phases were determined and were compared with previous data reported in the literature for low-scale rosemary supercritical extraction.
A two-stage depressurization procedure was accomplished and the effect of both on-line fractionation and extraction time on the antioxidant activity of the samples collected was studied. The antioxidant activity of the different fractions could be straight correlated with the carnosic acid content with a regression coefficient of 0.92This work has been financed by Universidad Autónoma de Madrid and Comunidad Autónoma de Madrid (ALIBIRD-S2009/AGR-1469) and project FUN-C-FOOD, CSD2007-00063 (CONSOLIDER-INGENIO) from Ministerio de Ciencia e Innovación, Spain
Paralelización con CUDA de algoritmos de verificación facial
Los delitos y fraudes derivados de la suplantación de identidad generan pérdidas millonarias para empresas y naciones. Hoy en día existen diversos métodos biométricos para la verificación de identidad. Entre ellos se encuentra la verificación facial, de gran interés práctico por su carácter no intrusivo.
Los algoritmos que se aplican para la verificación facial tienen un alto coste computacional, dificultando su uso en aplicaciones de tiempo real. Sin embargo estos algoritmos presentan un alto grado de paralelismo a nivel de datos que podría explotarse xon plataformas multicore.
En la actualidad uno de los principales exponentes de las plataformas multicore son las unidades de procesamiento gráfico (GPU). En este proyecto se ha abordado la implementación de diversos algoritmos de verificación facial en GPU. Los resultados en términos de rendimiento han sido altamente satisfactorios, llegando a obtenerse speedups superiores a 200 en comparación con implementaciones paralelas tradicionales (OpenMP). Asimismo se ha desarrollado una interfaz gráfica que permite realizar la verificación de la identidad de una persona apartir de dos fotografías con cualquiera de los métodos implementados.
[ABSTRACT]
Crime and fraud derived from identy theft produce loss of millions to enterprises and nations. Nowadays there exist several biometric methods for identity verification. One of them is facials recognition, of great practical interest due to its non-instructive character.
The algorithms applied to facial verification demand high computational cost, making it difficult to use them in real-time applications. However, these algorithms show a large degree of data-level parallelism which could be exploited with multi-core platforms.
One of the main current representatives of multi-core platforms are graphics processing units (GPUs). This project deals with the implementation of several face verification algorithms in GPUs. The performance results were highly satisfactory, reaching speedups of 200 when compared to traditional parallel implementations (OpenMP). Furthermore, a graphical interface that allows performing identity verification of a person with any of the implemented methods was developed
Integral field spectroscopy of HII regions in M33
Integral field spectroscopy (IFS) is presented for star forming regions in
M33. A central area of 300 x 500 pc^2 and the external HII region IC 132, at a
galactocentric distance {\sim} 19arcmin (4.69 kpc) were observed with the
Potsdam Multi Aperture Spectrophotometer (PMAS) instrument at the 3.5 m
telescope of the Calar Alto Hispano- Alem\'an observatory (CAHA). The spectral
coverage goes from 3600 A to 1{\mu}m to include from [OII]{\lambda}3727 A to
the near infrared lines required for deriving sulphur electron temperature and
abundance diagnostics. Local conditions within individual HII regions are
presented in the form of emission line fluxes and physical conditions for each
spatial resolution element (spaxel) and for segments with similar H{\alpha}
surface brightness. A clear dichotomy is observed when comparing the central to
outer disc HII regions. While the external HII region has higher electron
temperature plus larger H{\beta} equivalent width, size and excitation, the
central region has higher extinction and metal content. The dichotomy extends
to the BPT diagnostic diagrams that show two orthogonal broad distributions of
points. By comparing with pseudo-3D photoionization models we conclude that the
bulk observed differences are probably related to a different ionization
parameter and metallicity. Wolf-Rayet features are detected in IC 132, and
resolved into two concentrations whose integrated spectra were used to estimate
the characteristic number of WR stars. No WR features were detected in the
central HII regions despite their higher metallicity.Comment: 72 pages, 37 figure
Application of a liquid scintillation counter to the measurement of tracing radioactivity in experiments on suspended matter uptake in aquatic environments
The experiments on the study of the kinetic transfer coefficients of conservative and non-conservative radionuclides, in aquatic environments, need to determine radionuclide activity in large number of samples. Different radioactivity measurement techniques can be selected for analyses, but the liquid scintillation technique is preferred due to its easy sample treatment and its low time consumption. Samples are initially traced with a known activity of a selected radionuclide (2 3 9Pu, M IAm or "Tc). The transference of radionuclides, from the water to the suspended matter, is studied through the determination of the residual activity in aliquots of water sample, which are successively collected with time. In this work, we present the experimental procedures used for the 2 3 9Pu, 2 4 1Am and "Tc activity measurement by liquid scintillation counting, using a Wallac Quantulus 1 2 2 0 spectrometer. Results of the application of this technique to traced water samples are also shown in this study.ENRES
Volatile organic compounds and consumer preference for meat from suckling goat kids raised with natural or replacers milk
Most of European Union goats are slaughtered with carcase weights between 5 kg and 11 kg. Some farmers rear kids with milk replacers to produce cheese with the dams’ milk. The aim of this experiment was to study the volatile compounds (VOCs) of meat of suckling light kids reared with natural milk or milk replacers and to study the influence of consumers’ psychographic characteristics on the sensory preference for meat. Gas chromatography-mass spectrometry was performed to identify the VOCs and consumers evaluated the flavour, juiciness and overall acceptability. Thirty-five VOCs were detected and 44.3%, 25.1%, 6.9% and 2.3%, were aldehydes, hydrocarbons, ketones and alcohols, respectively. The influence of the rearing system on VOCs clearly depended on the breed. The use of milk replacers did not affect the percentage of linear aldehydes compared to the use of natural milk. However, the major aldehyde, hexanal (34.8%), was related to the use of natural milk and correlated positively with both the flavour (r = 0.21) and overall acceptability (r = 0.24). On the other hand, hydrocarbons such as hexane were related to MR, and 2-methyl-pentane and 3-methyl pentane were correlated with the acceptability of flavour (r = −0.22 and −0.25, respectively) and with the overall acceptability (r = −0.21 and −0.24). The 2-penthyl furan and 2-ethyl-1-hexanol were correlated with the overall acceptability (r = −0.22 and −0.22, respectively). Therefore, the acceptability of meat from suckling kids fed natural milk was greater for older consumers and people with a moderate consumption of meat.Unión Europea, Ministerio de Economía y Competitividad (MINECO).
