Influences of the Fish-Mouth Project and the Groins on the Flow and Sediment Ratio of the Yangtze River Waterway

A depth-integrated two-dimensional numerical model of current, salinity and sediment transport was proposed and calibrated by the observation data in the Yangtze River Estuary. It was then applied to investigate the flow and sediment ratio of the navigati

Pool Boiling In Microgravity: Recent Results And Perspectives For The Project Depa-Sj10

Two research projects on pool boiling in microgravity have been conducted aboard the Chinese recoverable satellites. Ground-based experiments have also been performed both in normal gravity and in short-term microgravity in the Drop Tower Beijing. Steady boiling of R113 on thin platinum wires was studied with a temperature-controlled heating method, while quasi-steady boiling of FC-72 on a plane plate was investigated with an exponentially increasing heating voltage. In the first case, slight enhancement of heat transfer is observed in microgravity, while diminution is evident for high heat flux in the second one. Lateral motions of bubbles on the heaters are observed before their departure in microgravity. The surface oscillation of the merged bubbles due to lateral coalescence between adjacent bubbles drives it to detach from the heaters. The Marangoni effect on the bubble behavior is also discussed. The perspectives for a new project DEPA-SJ10, which has been planned to be flown aboard the Chinese recoverable satellite SJ-10 in the future, are also presented.

H. D. Mandrioni y la psicología : homenaje al maestro

Resumen: La producción del Dr. Pbro. H. D. Mandrioni metafóricamente podemos decir que configura un tetraedro, un espacio establecido entre cuatro planos: Teología (propuesto como carabase), Filosofía, Psicología y Arte. Expondremos su posición acerca de la Psicología, a partir de sus textos filosóficos, poéticos, y de sus clases. Recorreremos diferentes temáticas: psicología como ciencia, problemas en el abordaje de su método y objeto. Desde allí reflexionaremos acerca de lo psíquico, su estructuración, su desarrollo u ontogénesis del yo; el proyecto vocacional y las dificultades que éste encuentra en el mundo actual, mundo de la tecnociencia, culminando con la relación entre psicología y arte, dando especial importancia a la “novela” en la formación del psicólogo.
