ORIENTE E OCCIDENTE ALL'EXPO OSAKA 1970
2013
The writer remarks the technological innovation and contamination developed at the first World’s Fair held in Asia. He analyzes issues and methods of the master plan for the Osaka EXPO ’70, through a critical reading of Pavillon Plaza and Festival Plaza designed by Kenzo Tange and Arata Isozaki the emblematic covered area, facing the central EXPO square, reminds the utopia of the 60th architecture.
Oriente en la Exposición Universal de Osaka 1970
2016
La Exposicion Universal de Osaka en 1970 se propone como posible modelo de una nueva ciudad, en la cual los elementos efimeros tienden a estarmucho más presentes que la arquitectura misma, la cual se limita a definir el esqueleto del sistema constrùctivo. El tema propuesto pretende evidenciar un nuevo acercamiento a las consecuencias de la ideologia del progreso de la civilisación y la tecnologia con referencia a la Segunda Guerra Mundial como ejemplo destructivo del knowhow cientifico.
Pheromone-binding proteins of scarab beetles.
1998
: We have characterized Pheromone binding proteins (PBPs) present in the antennae of several species of scarab beetles. In most cases there was only one class of PBP, which was expressed in both sexes. Both Anomala osakana and Popillia japonica possess a single PBP, highly homologous to each other. In each species the same PBP seems to recognize both enantiomers of japonilure, which have opposite biological functions, i.e., the sex Pheromone and the behavioral antagonist (stop signal). The purified PBP of A. osakana binds both enantiomers apparently with the same low affinity. Unexpectedly, these ligands were bound by moth PBPs, which utilize Pheromones with unrelated structures. These find…
Biosynthesis of scarab beetle pheromones. Enantioselective 8-hydroxylation of fatty acids
1999
Chemical communication in scarab beetles (Coleoptera: Scarabaeidae) is achieved with a wide variety of pheromones, but one typical structure is the γ‐lactone having a long unsaturated hydrocarbon chain. Several species utilize (R,Z)‐5‐(–)‐(oct‐1‐enyl)‐oxacyclopentan‐2‐one (buibuilactone), (R,Z)‐5‐(–)‐(dec‐1‐enyl)‐oxacyclopentan‐2‐one and (S,Z)‐5‐(+)‐(dec‐1‐enyl)‐oxacyclopentan‐2‐one [(R)‐japonilure and (S)‐japonilure]. Using deuterated precursors, we have demonstrated that these compounds are biosynthesized from fatty acids. (9,10‐d4)‐Palmitic acid, (9,10‐d4)‐stearic acid, (9,10‐d2)‐palmitoleic acid, (9,10‐d2)‐oleic acid, (9,10‐d2)‐8‐hydroxypalmitoleic acid and (9,10‐d2)‐8‐hydroxyoleic acid…
