Consequently, the dominant drying mechanism found in PA is evaporation at the free surface of water islands within the specimen, followed by water vapor diffusion to the top surface and its subsequent convection by airflow.
In these circumstances, it is likely that the nebulized saline assisted the expectoration of copious overnight secretions in the airways with some subsequent improvement in airflow.
Subsequent treatment of the obstructive nasal airflow is described.
Although an improvement in hyposmia was the only benefit noted with initial oral steroid treatment in subjective outcomes, the objective outcomes confirmed the additional treatment effect, at least in polyp size reduction and increased nasal airflow, of oral steroids on subsequent nasal steroids in nasal polyposis.
For example, there is evidence from dryland southern Africa that the delayed increase in leaf area that follows rainfall reinforces subsequent winds and precipitation such that 'the vegetation draws airflow toward itself in a self-sustaining way' (Chikoore and Jury 2010).
16, 62 However, recent prospective CT-based studies suggest mild emphysema, in the absence of airflow limitation, may lead to overinflation (from air trapping) that heralds subsequent accelerated FEV1 decline.
Allergic asthma has been regarded as an atopic disease involving allergen exposure, allergic (IgE-mediated) sensitization with a Th2 CD4+ lymphocyte response and subsequent interleukin (IL -5-mediated eosIL -5-mediatedays IL -5-mediatedreosinophilicenhairwaysronchinflammationty and resultinge ainflow obstruction [ 1].
Contrary to the key early evidence in the late 1960s to early 1980s that laminar airflow and body exhaust suit reduced wound contamination and SSIs, 1 34 a number of subsequent studies in the 1980s and 1990s found no convincing evidence that laminar airflow was effective in reducing SSIs compared with conventional ventilation.
The combination of airflow turbulence, the physical epithelial mucosal barrier, the trapping of particulates in mucus and their subsequent removal via mucociliary transport, results in the nose and upper airways largely preventing entry of particles greater than 2 μm (Nicod, 2005).
Five consecutive cycles were performed, yielding complete removal of CO2 from a continuous airflow containing 500 ppm of CO2 within a residence time of 1.3 s during each carbonation step, and subsequent complete release of CO2 and regeneration of the CaO reacting particles during the calcination step.
