Estudio de materiales para evitar la formacion de espuma en plantas de agua pesada. Estabilidad termica. Pte. 2. (Antifoaming materials in G.S. (Girlder sulfide) heavy water plants. Thermical stability. Pt. 2).
1986-01-01

In Girlder sulfide (G.S.) heavy water plants hydrogen sulfide-water systems are inherentely foaming, so the adding of antifoaming materials is of great importance. These may be of high volatility, pyrolizable or chemically unstable in plant operation cond...

RESUMEN. La presencIa de flujos coljmados asocjados con objetos estelares j6venes es un fen6meno comun en reglones de formacI6n estelar. Estos chorros frecuentemente muestran una cadena de reglones de lineas de emjsI6n, a varIas de las cuales se les conoce desde bace mucho tlempo objetos HerbIg-Haro (HAl). En el presente trabajo examjnamos la poslbIlI dad de que estos nudos sean condensaciones ...
