Methods In this study, the VHC called Tipshaler (Protec’som, France) was evaluated with fluticasone (Flixotide, 50μg/dose, GSK, France) and beclomethasone (QVAR, 100μg/dose, MEDICIS, Canada). The method according to the European Pharmacopoeia used a constant flow rate (30 L / min) was used. Particle size distribution was measured using a NGI cascade impactor (Copley Scientific, Nottingham, Unit...

In this study a new passive, large particle impactor (PLPI) (PM<10) was developed and evaluated in a wind tunnel. The PLPI is designed to be isoaxial and isokinetic to enable large particles sampling without bias. The PLPI can provide representative sampling without requiring a mass flowmeter controller or pump. The PLPI is especially useful for aerosol wind tunnel studies to evaluate particle ...

The manuscript describes measurements of the viscosity of secondary organic aerosol (SOA) samples derived from the oxidation of the anthropogenic precursor toluene using poke-flow and bead mobility techniques. The results are compared with previous measurements for the system derived from impactor measurements and uptake measurements of ammonia, and contrasted with previous measurements for SOA...

This review covers studies dealing with simplified analytical models for ballistic penetration of an impactor into different solid media, namely, metals, soil, concrete, and composites at high speeds, but not at hypervelocities. The overview covers mainly papers that were published in the last decade, but not analyzed in previous reviews on impact dynamics. Both mathematical models and their en...

Glassy ejecta are associated to a limited number of impact craters, and yet hold key information about hypervelocity processes. Here we report on the discovery ∼650 km2 glass strewnfield in Central Depression Atacama Desert. These cm-sized splash-form objects, that refer as atacamaites, essentially composed dacitic formed by high-temperature melting local magmatic rocks, with addition variable ...

Somatosensory evoked potentials (SEPs) were obtained from 15 rats that were inflected with graded injury using the NYU Impactor. SEPs, in response to stimuli to the nerves in the limbs, were recorded from the cranium. Spectral coherence was used to analyze these signals. Results obtained from the investigation show that this technique is capable of providing a quantitative measure of spinal cor...
