The dynamic and small-scale spatial variability of bio-optical processes that occurs in coastal regions and inland waters requires high resolution satellite ocean color feature detection. The Visual Infrared Imaging Radiometer Suite (VIIRS) currently utilizes five ocean color M-bands (410,443,486,551,671 nm) and two atmospheric correction M-bands in the near infrared (NIR; 745,862 nm) to produc...

the reaction of ch3o2 radicals with acetaldehyde on the solid surface of nh4no3 has been studied in a flow capillary reactor at low pressure and room temperature. the experiments were performed using epr spectrometer combined with the kinetic method of radicals freezing. peroxy radicals revealed an oscillation complex behavior during the process regarding to the phenomenon of radicals multiplic...

This field study investigated the relationship between indoor and outdoor concentrations of airborne actinomycetes, fungal spores, and pollen. Air samples were collected for 24 h with a button inhalable aerosol sampler inside and outside of six single-family homes located in the Cincinnati area (overall, 15 pairs of samples were taken in each home). The measurements were conducted during three ...

inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. the present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (pec) based microparticles containing antibacterials for the treatment of lung infections.chitosan polyelectrolyte complex...

background: welding is one of the most exercised industrial processes which welders are exposed to chemical and physical hazardous agents. this study was conducted to evaluate occupational and environmental exposures to aerosols generated by welding processes in a factory. methods: a total of 28 samples of aerosols were collected at 4 different locations including indoor, outdoor, source of wel...

The effect of the surface roughness of solid atmospheric aerosol particles on their heterogeneous nucleation capability has been examined using the concept of Aself-affineB rough surfaces. The surface roughness has a great influence on the contact angle between the particle surface and the nucleating liquid droplets. Roughness enhances wetting and the rate of heterogeneous nucleation from the v...
