The design of the geometry and bypass positioning in a mixing section, and the idea of regulation, as well as integration, with a suction nozzle duct was described.
Surgical silk sutures (6/0, CP Medical, Portland, OR) were inserted into the cheek skin to gently pull them laterally to prevent occlusion of the naso-palatine duct during suction.
Following a second delay of 40 s, a solenoid controlling suction to the nasopalatine duct was opened and 1 2 ml of Ringer's solution was passed through the nostril and out the nasopalatine duct to cleanse the VNO.
In this study, the concept of an R744 ejector with a bypass duct of a suction nozzle was presented.
Pressure measurements show that, the origin of the duct thrust is suction effect induced by the propeller in converging part (forebody) of the duct, and magnitudes of pressure coefficients inside forebody diminish with increasing advance ratio.
For many years a small group of investigators pioneered methods to collect fluids and exfoliated cells from the breast ducts by applying suction (nipple aspiration) to the openings, and exfoliative cytology revealed that breast cancer-associated abnormalities could be detected in these samples [ 1- 6].
To allow for cleaning the nasal cavity and the VNO between different stimulus presentations (see below), a plastic tube was inserted below the mouth to allow suction of fluid through the nasopalatine duct.
It may be theoretically possible to pump in style, but breast-feeding does not readily lend itself to automation: where a baby's mouth presses intelligently on the breast to release milk from the duct, the Medela employs a suction method abetted by a hard, ill-fitting breast shield with a bottle dangling from it.
Interestingly, all 11 DL samples demonstrating aberrant methylation were from ducts that yielded fluid with nipple suction aspiration.
