Fe y esperanza. Los juicios de valor en el pensamiento de E.H. Gombrich
2002
Este artículo trata de las teorías de E.H. Gombrich sobre la fundamentación de los juicios de valor histórico y estético, así como de sus puntos de vista sobre el canon histórico-artístico, el relativismo cultural, el gusto artístico, y la tradición. Por un lado señala la innecesaria confusión entre relevancia histórica y valor histórico en que incurre Gombrich; por otro, resalta su decisión al defender el compromiso y los valores como un elemento clave para el conocimiento histórico-artístico. La base de este estudio se encuentra en su conferencia La historia del arte y las ciencias sociales, y en un texto de Francis Haskell, ambos de 1973.

Influence of substrate and temperature on the biodegradation of polyester-based materials: Polylactide and poly(3-hydroxybutyrate-co-3-hydroxyhexanoa…
2020
[EN] The extended use of polymers from renewable resources such as aliphatic polyesters or polyhydroxyalkanoates boosted the necessity to understand their behaviour in an end-of-life scenario. Although they can be degraded in reasonable shorter times than traditional polymers, understanding the degradation mechanisms under dissimilar conditions will contribute to further developments in this field. This work aimed to study the effect of temperature and substrate in the degradation of polylactide (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) in a simulated laboratory scale to ascertain their contribution, separately or in combination. For this purpose, nine parallel degradat…
Religious Self-definition, Mass Attendance, Importance of God, and Hopelessness among Spanish Undergraduates
2011
The aim of this work was to examine the relationship between religious self-definition, attending Mass, the importance of God, and hopelessness under the hy-pothesis that these religious variables and hopelessness are negatively related. The par-ticipants were 273 Spanish undergraduates who were incidentally recruited. and who completed three religious items and the Spanish version of a Hopelessness Scale. The Chi-squared test and Bonferroni test were used in the statistical analysis. The results indicate that there were no statistically significant differences between the religious self-definition and attending Mass groups in relation to hopelessness, whereas there were differences between…
Millares Carlo en el exilio
2010
El artículo describe la trayectoria del conocido historiador y paleógrafo Agustín Millares Carlo, exiliado tras la guerra civil: su carrera en España, sus destinos y aportaciones científicas en México; en especial, su vinculación con la Universidad Nacional Autónoma de México, a través del expediente académico. Así como las consecuencias que supuso el exilio de profesores para las universidades españolas. El fraude cometido por el estado franquista durante la postguerra al editar obras de exiliados a nombre de otros… Acaba el trabajo con una breve consideración sobre la universidad. This article describes the trajectory of the well-known historian and paleographer Agustín Millares Carlo, ex…
Influence of agents that act on DNA and RNA synthesis on the activity of poly(ADP-Rib) polymerase
1975
The activity of poly(ADP-Rib) polymerase is enhanced in the presence of spermine and spermidine. Among the adenosine-like antibiotics tested, only formycin B and showdomycin cause an inhibition of the enzyme, which is competitive to NAD. The activity of poly(ADP-Rib) polymerase is not reduced by rifamycin, alpha-amanitin and 2-phenylethanol.

On Adcatomus ciudadus Karsch 1880, a remarkable spider species from Lima, with comments on South American Sparassidae (Arachnida, Araneae)
2008
The ♂-holotype of Adcatomus ciudadus Karsch 1880 was located in the Zoologisches Museum der Humboldt-Universitat Berlin and recognized as a representative of the spider family Sparassidae. A redescription of the holotype is given and the systematic position of the species is discussed. A review on taxonomic work on South American Sparassidae is also given. Der ♂-Holotyp von Adcatomus ciudadus Karsch 1880 wurde im Zoologischen Museum der Humboldt-Universitat Berlin ausfindig gemacht und als Vertreter der Spinnenfamilie Sparassidae identifiziert. Der Holotyp wird beschrieben und seine systematische Stellung diskutiert. Es wird ein zusammenfassender Ruckblick auf taxonomische Arbeiten uber sud…
Sparassidae of Japan. I. New Species of Olios, Heteropoda, and Sinopoda, with Notes on Some Known Species (Araneae: Sparassidae: Sparassinae and Hete…
2000
Four new species of the spider family Sparassidae are described from Japan under the names Olios japonicus sp. nov., Heteropoda simplex sp. nov., Sinopoda okinawana sp. nov. and S. tanikawai sp. nov. The genus Olios is recorded for the first time from Japan. Taxonomical notes and new records of some known species and comments on diagnostic characters of the subfamilies and genera of the Japanese Sparassidae are presented.
First records of the genera Pseudopoda, Sinopoda, and Olios from Taiwan with descriptions of four new species (Araneae: Sparassidae)
2001
Four new species of the spider family Sparassidae are described from Taiwan: Pseudopoda serrata sp. nov. (male and females), Pseudopoda recta sp. nov. (female), Sinopoda exspectata sp. nov. (male), and Olios scalptor sp. nov. (male). These represent first records of the three genera for Taiwan. A record of Heteropoda venatoria (Linne 1767) is also reported.
