The statistical approach identified the effect of five independent parameters on the selected performance characteristics and the effectiveness of heat and mass transfer processes in the channels of the cross-flow M-cycle exchanger was found to be significantly influenced by supply airflow mass flow rate, inlet air temperature and relative humidity.
On the 27 trials realized in three rats, we never observed a slow rhythm induced by a continuous nasal airflow whatever the flow rate condition (Figure S2).
From Fig. 15, the flow control valve smoothly changed the airflow except at low flow rate.
If the particle can be separated from the airflow at the minimum flow rate, which is the minimum volume flow rate of the ECP fan, then it must be possible to separate it by centrifugal force when the flow rate is higher than the minimum flow rate.
First, we tested the effect of the presence of a respiration-modulated deodorized airflow (nasal airflow ON, 500 ml/min at the basal flow rate) versus its absence (nasal airflow OFF) in the nasal cavity on OB spontaneous activity (96 trials for each condition, with 45 cells detected).
After blotting dry, seeds were transferred to a laminar airflow cabinet with an air flow rate of 880 m min−1 (measured using a heavy-duty Vane anemometer model 407113; Extech Instrument Corporation, Waltham, MA, USA).
At diluting airflows 0.5-4.0 0.5-4.0nd vacuum fL/minand 5 ml/min/well through the exposure module, mean particle deposition was in the range 8.65 ± 1.51 μg/cm2-0.72 ± 0.13 μg/cm2.
Comparatively, it can be said that the effect of airflow in airflow window is proportional to inlet temperate and flow rate, but the effect of temperate is higher than the effect of flow rate.
At the time of the treadmill test, 2 rats were simultaneously placed on a 2-track treadmill (Columbus Instruments, Columbus, OH) at a constant 5% grade enclosed by a metabolic chamber (Oxymax Deluxe, Columbus Instruments) through which airflow was maintained at a constant flow rate.
The work was performed in two stages: 1) monitoring of the fluidization regimes during the development of the coating process without control and 2) control of the airflow rate and of the coating suspension flow rate using PI controllers.
