No full textPhotograph of Mateo S. Perez (September 19, 1908 - December 25, 1995) near a window surrounded by plants, undated. He was from San Mateo, Rizal, Philippines and arrived in Washington, D.C. in 1929. He was married to Consuelo Perez and had a daughter, Amelita (Perez) Mondonedo. An article with excerpts from an interview between Mateo Perez and Rita Cacas can be found on the Rita M. Cacas Foundation website here: http://rmcacas.foundation/1994-washington-post-article.html. This photograph may have been taken 1993-1994, during Rita Cacas's interview with Mr. Perez

Mateo Alemán, from Judge to Author: Articulations of Authority from the informe secreto (1593) to Guzmán de Alfarache (1599)
No full textThe present article studies Mateo Alemán’s authorial persona in both his nonliterary
and his literary work. Using the notion of the author function, we will discuss
continuities and fissures between the Informe secreto and Guzmán de Alfarache. In doing so,
we shall explore the ways in which the construction of the figure of the author manifests itself
beyond the fictional/factual divide
ON THE MASS DISCREPANCY OF THE CEPHEID STARS
No full textIn this paper we examine the problem of the mass discrepancy of Cepheid stars in the young, rich LMC cluster NGC 2157 observed by Mateo and coworkers, which is known to possess three Cepheids. The simultaneous fit of the color-magnitude diagram with theoretical simulations based on models for intermediate-mass stars incorporating either semiconvection or overshoot in the central cores, and with suited chemical composition (the evolutionary masses of the Cepheids are therefore automatically known), and the derivation of the pulsational masses from the Cepheid models of Chiosi & Wood allow us to show that the problem of mass discrepancy likely originates from the adoption of semiconvective models and insufficient accuracy in the determination of the mass by one of the two methods. When this is feasible, as in the ideal laboratory given by the young LMC clusters with Cepheids, the discrepancy no longer exists. Finally, an independent estimate of the distance modulus based on the equality between the evolutionary and pulsational mass of the Cepheid stars is presented. The new method gives a distance modulus in agreement with previous determinations

Acid hydrolysis of olive tree leaves: Preliminary study towards biochemical conversion
No full textOlive tree leaves, an abundant agricultural by-product without enough industrial market outlets, are presented in this study as a relevant resource of available carbohydrates to be chemically treated for monomeric sugar production. Characterization of two main granulometric fractions is the starting point for testing the specific effect and the relevance of three main factors (time, temperature, and sulfuric acid concentration) on diluted acid hydrolysis with respect to oligosaccharides, simple sugars, and fermentation inhibitory compounds production. The selected conditions (100°C, 90 min, and 6% w/w H2SO4) to perform the small scale hydrolytic process, considering response surface methodology (23 factorial design with center points), implied production of acetic acid and hydroxymethylfurfural in concentrations not exceeding 1.10 kg m-3 and 0.25 kg m-3, respectively. Thus, these experimental conditions were the reference framework to evaluate the effect of a meaningful scaling stage in a hydrolysis reactor, considering kinetic parameters based on hydrolysis rates and D-glucose and D-xylose generation
THE STAR FORMATION HISTORY OF THE LARGE MAGELLANIC CLOUD
No full textWe present deep photometric observations of stars in three fields of the Large Magellanic Cloud (LMC) and interpret these data using synthetic color-magnitude diagrams (CMDs) and luminosity functions (LFs) generated from the overshoot models of Bertelli et al., Bressan et al., and Aparicio et al. We can successfully model the field CMDs and LFs with a star formation rate that experienced a large increase (4 +/- 0.5) x 10(9) yr ago. The precise age of this "burst" depends sensitively on the characteristics of the models. Classical (i.e., nonovershoot) models yield a burst age about 2 x 10(9) yr younger than the value we obtain. An initial mass function with slope of 2.35 (the Salpeter value) and a mean field star metallicity of [Fe/H] approximately -0.7 are consistent with the photometric data and LFs. Furthermore, our primary conclusion, that is, the possibility of a single burst of star formation, depends on the distance modulus adopted for LMC. If (m - M)0 = 18.4, we find evidence for a single burst throughout the LMC. If (m - M)0 = 18.6, this is no longer possible. Given the differences between the ages derived using overshoot and classical models, the age distribution we derive for LMC field stars older than about 1 x 10(9) yr is similar to that found by earlier studies using deep photographic observations of other fields throughout the LMC, and with the observed age distribution of intermediate-age and old LMC star clusters. This suggests that the star formation rate in the LMC was globally quite low during at least the first half of its lifetime, and that a major event triggered a substantial and relatively sudden increase in the star formation rate throughout the entire LMC which persisted for several 10(9) yr and even up to the present epoch in some parts of that galaxy

El efecto San Mateo
No full textThe author refers to the verse 13 of chapter 19 of the Gospel attributed to Matthew, which reads: "because whoever has, more will be given to him, and he shall have abundance: but whosoever hath not, even what he has will be taken", and links this to the sociology of science, stating the "Matthew effect"-eminent scientific researchers reap much more nourished applause, than other researchers, less known, for equivalent contributions- for exposing the social stratification of scientific communities.El autor recoge el versículo 13 del capítulo 19 del Evangelio atribuido a San Mateo reza así : "porque a cualquiera que tiene, le será dado, y tendrá más; pero al que no tiene, aún lo que tiene le será quitado", y lo vincula a la sociología de la ciencia, para a través del "efecto San Mateo" -los investigadores científicos eminentes cosechan aplausos mucho más nutridos, que otros investigadores, menos conocidos, por contribuciones equivalentes- exponer la estratificación social de las comunidades científicas
