Many patients have incorrect aerosol inhalation technique with metered dose inhalers (MDI). Several inhalation aids have been developed and marketed for these patients. Even those who have correct inhalation technique may benefit from these devices. We compared bronchodilator efficacy of two puffs of albuterol aerosol administered either directly from a MDI mouthpiece, or from an inhalation aid...

East China is among the fastest developing area in Asia, where atmospheric aerosol loading is high due to heavy urban and industrial emission. The Moderate Resolution Imaging Spectroradiometer (MODIS) level 2 aerosol products (2000–2007) were used to study aerosol spatial and temporal distributions, as well as their variations with local meteorological conditions over East China. By combining A...

Black carbon (BC), one of the major components of atmosphere aerosol, could be the second dominant driver of climate change. We reconstructed historical trend of BC fluxes in Sanjiang Plain (Northeast China) through peat record to better understand its long-term trend and relationship of this atmosphere aerosol with intensity of human activities. The BC fluxes in peatland were higher than other...

CS aerosol (o-chlorobenzylidene malonitrile) is a low to moderate toxicity irritant used by Australian Defence Force for respiratory protection training. It is classified as a hazardous substance with an occupational exposure limit of 0.39 mg/m3 (STEL-C). Currently the ADF has no means of measuring the concentration of CS aerosol used within the Mask Test Facilities (MTF) during CBRN training. ...

Aerosol optical depth measurements over Bahrain acquired through the ground-based Aerosol Robotic Network are analyzed. Optical depths obtained from ground-based sun/sky radiometers showed a pronounced temporal trend, with a maximum dust aerosol loading observed during the March to July period. The aerosol optical depth probability distribution is rather narrow with a modal value of about 0.25....

Aerosolized antibiotics are potentially useful in intensive care. At State University of New York at Stony Brook we developed a human model of tracheobronchitis in intubated patients. The model provides daily specimens of airway secretions, allowing serial studies of airway inflammation and testing of therapy modes. The presence of local infection is defined by a unique method of quantified spu...

[1] Using internally consistent albedo, aerosol, cloud, and surface data from the Multiangle Imaging Spectroradiometer (MISR) instrument onboard the Terra satellite, top-of-atmosphere (TOA) spectral albedo change (da) in the presence of aerosols over land is estimated and its dependence on aerosol and surface properties is analyzed. Linear regressions between spectral TOA albedo and aerosol opt...
