Similarities and differences for describing the mean mass granule diameter from these are discussed.
The nebulizer generated particles with a mean mass median diameter of 5.4 μm at an output of 2.2 ml/min.
All institutions utilize nebulizers that generate an optimal mean mass aerodynamic diameter of the aerosol particles of 1 5 μm for delivery of aerosolized colistin [ 10].
Particle size (mean mass aerodynamic diameter (MMAD)) of the nebulised formulation was measured using a Mercer-style impactor (In-Tox Products INM., Moriarty, NM, USA) operated at approximately 2.0 l min−1.
All subjects were pre-treated with 180 μg albuterol administered by metered-dose inhaler and then inhaled nebulized sterile 3% saline for 20 min from an ultrasonic nebulizer [DeVilbiss Ultra-Neb 99; DeVilbiss Air Power Co., Jackson, TN; this nebulizer generates particles of a mean mass median diameter of 3.5 μm and has an output of 5.9 mL/min].
Mean maximum mass diameter was 25.4±0.9 mm.
Through various in vitro characterizations, it was shown that drug loaded microparticles had a high drug loading with promising aerosolization characteristics (mean volume diameter (Dv50) 3–4 μm, experimental mass mean aerodynamic diameter (MMADe) 4 4.5 μm, fine particle fraction (FPF%) 40 45%, emitted dose (ED%) 94 95%).
The values of length, mass, diameter, geometric mean diameter and sphericity of wild plum fruit were established as 28.14 mm, 15.33 g, 30.16 mm, 29.47 mm and 1.04, respectively.
The fruit mass, diameter, volume, geometric mean diameter, sphericity and projected area were measured as 11.98 g, 27.68 mm, 13.68 cm3, 28.86 mm, 0.92, and 9.25 cm2, respectively.
We measured size-fractionated 24-hr mean mass concentrations (μg/m) of quasi-UFPs, 0 0.25 μm in diameter (PM0.25); accumulation-mode particles, 0.25 2.5 μm in diameter (PM0.25 2.5); and coarse mode particles, 2.5 10 μm in diameter (PM2.5 10).
