in the present study, experimental investigations about the hydrodynamics of the conical cap tray (concap tray) have been carried out. the concap tray is an innovative and novel type of cap trays. the effect of the different weir height (2.5, 5 and 7 cm) on the weeping, entrainment and the total pressure drop for the concap tray was measured, compared and correlated. the hydraulic experiments w...

This paper addresses an experimental investigation in the hydrodynamic behavior of a modified slotted sieve tray. Slotted sieve tray (Push valve sieve tray) is a sieve tray that the push valves have been utilized on the tray deck to eliminate liquid gradients and non-uniformity of liquid distribution on the tray. The air-water system was used in an industrial scale experimental rig with an inte...

Atopic eczema (also known as atopic dermatitis) is a very common inflammatory skin condition.(Guidelines 2006) It is characterised by an itchy red rash that typically tends to involve the skin creases (e.g. behind the knees, folds of elbows, around the neck), and is usually relatively mild.(Emerson 1998) In the acute stage, eczematous lesions are poorly defined and red with oedema, vesicles, an...

Arbuscular mycorrhizal fungi (AMF) are mutualistic symbionts associated with most terrestrial plants. HMA communities vary in composition and life histories affected by land use management. The caldén forests (Prosopis caldenia Burkart) the province of San Luis have suffered a considerable reduction their area. Currently, its relics part landscape made up lands cultivated Medicago sativa L. (al...
