THE INSERTION LOSS OF POROELASTIC PLATE SILENCERS IN A FLOW DUCT [PDF]

, 2008
Idealized silencers consisting of cavity-backed clamped porous elastic plates parallel to the direction of flow can result in low frequency attenuation of noise in the duct.

Morphology of the patent arterial duct : features relevant to treatment [PDF]

, 2008
Patent ductus arteriosus (PDA), one of the most common congenital heart defects, is an abnormal persistence of a patent lumen in the arterial duct due to an arrest of the natural process of closure after it has served its function as a vital channel ...

Efficient computation of spinning modal radiation through an engine bypass duct

, 2008
The aim of this work is to accurately and efficiently predict sound radiation out of a duct with flow. The sound propagation inside a generic engine bypass duct, refractions by the shear layer of the exhaust flow, and propagation in the near field are ...

The ultrastructure of the ejaculatory duct in the springtail Orchesella villosa (Geoffroy) (Hexapoda, Collembola) and the formation of the spermatophore

, 2012
The initial part of the ejaculatory duct of Orchesella villosa contains a “valve” and a “sorter” avoiding respectively the reflow and allowing the separation of the secretion for the spermatophore stalk from the sperm fluid.

Analytical modelling of sound transmission in a lined duct

, 2013
The focus of this thesis is on the prediction of sound attenuation through a lined duct, based on a mathematical model. Ducts with a single section as well as multi-segmented sections are discussed. The duct of interest has a rectangular cross-section as

The sex-peptide DUP99B is expressed in the male ejaculatory duct and in the cardia of both sexes.

, 2003
Mating elicits two postmating responses in many insect females: the egg laying rate increases and sexual receptivity is reduced. In Drosophila melanogaster, two peptides of the male genital tract, sex-peptide and DUP99B, elicit these postmating responses
