Polarity switch of PMMA powder transported through a PMMA duct [PDF]
arXivDuring pneumatic conveying, powder electrifies rapidly due to the high flow velocities. In our experiments, the particles even charge if the conveying duct is made of the same material, which might be caused by triboelectrification between two asymmetric contact surfaces.

Complex resonance frequencies of a finite, circular radiating duct with an infinite flange [PDF]
arXiv, 2009 Radiation by solid or fluid bodies can be characterized by resonance modes. They are complex, as well as resonance frequencies, because of the energy loss due to radiation. For ducts, they can be computed from the knowledge of the radiation impedance matrix.

Method for Observing Intravascular BongHan Duct [PDF]
arXiv, 2002 A method for observing intra blood vessel ducts which are threadlike bundle of tubules which form a part of the BongHan duct system. By injecting 10% dextrose solution at a vena femoralis one makes the intravascular BongHan duct thicker and stronger to be easily detectable after incision of vessels.
