BACKGROUND Inhaled recombinant human DNase I (rhDNase) improves clearance of visco-elastic secretions in patients with cystic fibrosis. Because of their portability, newer-generation vibrating-mesh nebulizers offer greater convenience for the patient, but their efficiency in delivering rhDNase has not been determined. METHODS We compared a newer-generation vibrating-mesh nebulizer (Omron Micr...
The mechanism of vibration energy transfer in a vibrating fluidized bed (VFB) is reported in this paper. A series of sensors was employed to simultaneously detect pressure wave propagation signals at different positions at various heights in the fluidized bed. The mechanism of vibration energy transfer in an VFB is found by wave propagation. The pressure wave was produced from a vibrating base ...
Nanocrystalline strontium hexaferrite (SrFe12O19) powders have been successfully synthesized using the facile Co-precipitation method. The ferrite precursors were achieved from mixtures of strontium and ferric chloride in an aqueous medium without any surfactant and soft template. The as-received powders were calcined at 800 and 1000 ˚C for 2 hours in air. The final powders were characterized b...
