Se comentan algunos táxones herborizados en los alrededores de la laguna de Villa y en los Andes Centrales, que presentan cierto interés ecológico y corológico.

Imagen y pliegue: en torno a una teoría de la cultura en "Paradiso" de José Lezama Lima

Estudio de la teoría de la cultura en la novela Paradiso (1966) del escritor José Lezama Lima en relación a las menciones a obras de pintura, escultura, arte-objeto, arquitectura y música, así como a los aspectos claves que la constituyen. La metodología utilizada se basa en la teoría del pliegue desarrollada en los postulados culturales y estético-filosóficos de Gilles Deleuze. La tesis consta de los siguientes capítulos: Introducción: El peso de lo irreal: Imagen, cultura, poética. I, Paradiso: La maison baroque. II, Galería de coral: Estudio libre de pintura y escultura. III, Arquitectura de la Imagen. IV, Sinfonía de la Imagen: con la música por dentro. El último capítulo realiza la interpretación y conclusión general, centrándose en las tres nociones que sustentan la teoría cultural del escritor: lo barroco como expresión cultural del ser americano, la imagen como clave cultural y el mito como espacio de la cultura.

The application of Near-Infrared Reflectance Spectroscopy (NIRS) to detect melamine adulteration of soya bean meal

Soya bean products are used widely in the animal feed industry as a protein based feed ingredient and
have been found to be adulterated with melamine. This was highlighted in the Chinese scandal of
2008. Dehulled soya (GM and non-GM), soya hulls and toasted soya were contaminated with melamine
and spectra were generated using Near Infrared Reflectance Spectroscopy (NIRS). By applying chemometrics
to the spectral data, excellent calibration models and prediction statistics were obtained. The coefficients
of determination (R2) were found to be 0.89–0.99 depending on the mathematical algorithm used,
the data pre-processing applied and the sample type used. The corresponding values for the root mean
square error of calibration and prediction were found to be 0.081–0.276% and 0.134–0.368%, respectively,
again depending on the chemometric treatment applied to the data and sample type. In addition, adopting
a qualitative approach with the spectral data and applying PCA, it was possible to discriminate
between the four samples types and also, by generation of Cooman’s plots, possible to distinguish
between adulterated and non-adulterated samples.

The use of handheld near-infrared reflectance spectroscopy (NIRS) for the proximate analysis of poultry feed and to detect melamine adulteration of soya bean meal

The use of handheld near infrared (NIR) instrumentation, as a tool for rapid analysis, has the potential to be used widely in the animal feed sector. A comparison was made between handheld NIR and benchtop instruments in terms of proximate analysis of poultry feed using off-the-shelf calibration models and including statistical analysis. Additionally, melamine adulterated soya bean products were used to develop qualitative and quantitative calibration models from the NIRS spectral data with excellent calibration models and prediction statistics obtained. With regards to the quantitative approach, the coefficients of determination (R2) were found to be 0.94-0.99 with the corresponding values for the root mean square error of calibration and prediction were found to be 0.081-0.215 % and 0.095-0.288 % respectively. In addition, cross validation was used to further validate the models with the root mean square error of cross validation found to be 0.101-0.212 %. Furthermore, by adopting a qualitative approach with the spectral data and applying Principal Component Analysis, it was possible to discriminate between adulterated and pure samples.
