Demulsification of water/sunflower oil emulsions by a tangential filtration process using chemically impregnated ceramic tubes
(Elsevier B.V., 2007-02-15)
A tangential filtration process was implemented in this study using porous ceramic tubes made of alpha-alumina produced by the slip-casting technique. These tubes were sintered at 1450 degrees C and characterized by mercury ...

Analisys of thermal efficiency of a modified solar collector type evacuated tube
(2014)
The need of renewable energy sources due to climate change and thus the search for clean energy sources, justify the growing investment on new types of solar collectors. The research has contributed to this expansion in ...
Two competing crack growth mechanisms in very high pressures tubes
(Elsevier, 2010-09-25)
This work addresses the influence of autofrettage in the occurrence of repeated leaks of thick wall straight and curved 4333M4 steel tubes from a high pressure petrochemical reactor, comprised by straight and curved tubes ...
Performance evaluation of a nonimaging secondary reflector on a commercial parabolic trough concentrator
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2010-05-16)
Parabolic trough concentrators are a proven technology in the field of solar power. Solar radiation is reflected by a linear parabolic mirror and concentrated onto the surface of an absorber tube with the purpose of ...
Changes during the menstrual cycle in cytosolic and nuclear concentrations of progestagen receptor in the human Fallopian tube
(1984)
[3H]R5020 was bound to cytosolic and nuclear samples of human Fallopian tube with high affinity and specificity. The cytoplasmic and nuclear concentrations of progestagen receptor varied, throughout the menstrual cycle, ...
Coeficiente de operación de un sistema formado por un refrigerador doméstico acoplado a un acumulador de agua caliente para la recuperación de energía
(2012-07-09)
An experimental apparatus containing a domestic refrigerator coupled to a vertical hot water storage tank was used for energy recovery. The original condenser of the refrigerator was maintained, but modified with a concentric ...
