In the article, a new air-blowing vacuum membrane distillation (AVMD) process is proposed, and it forms the air-liquid flows in the membrane by forcedly blowing airs to the hot feed liquids circularly flowing in the hollow fiber membrane, and forms the AVMD system to enhance the turbulent degree of the liquids. The intense disturbance of air bubbles and the strong cutting power at the surface o...

Eryngium caucasicum Trautv. (Apiaceae) is a perennial herbaceous plant with about one meter height, an endemic species that has been distributed in the northern parts of Iran. The plant leaves are normally used in medicine and food industries in Iran.The plant has several medicinal properties including enforcing generative power, diuretic, lenitive and appetizer. In this research differents par...

We calculate the spectral function A ρ of the ρ meson in nuclear matter. The calculation is performed in the low density approximation , where the in-medium self energy Σ med is completely determined by the vacuum ρ N forward scattering amplitude. This amplitude is derived from a relativistic resonance model. In comparison to previous non-relativistic calculations we find a much weaker momentum...

1,3-butadiene, bd is produced from c4-cut by extractive distillation. the separation of 1,3-butadiene from c4-cut is not possible through the conventional distillation processes, because several mixtures have consisted of close boiling points constituents and make azeotrope. the basf extraction distillation process in bd unit of jam and amirkabir petrochemical company improves the relative vola...
