< Cooking can generate appreciable aerosol within the area where cooking takes place. < Cooking aerosol is largely within the respirable size range. < Fatty acids and dicarboxylic acids are major components. < Other constituents are alkanones, alkanals, lactones, PAH, sterols and alkanes. < Raw food, cooking oil, cooking style and temperature affect aerosol composition. a r t i c l e i n f o

The MODerate resolution Imaging Spectroradiometer (MODIS) aboard both NASA's Terra and Aqua satellites is making near global daily observations of the earth in a wide spectral range (0.41 to 15 μm). These measurements are used to derive spectral aerosol optical thickness and aerosol size parameters over both land and ocean. The aerosol products available over land include aerosol optical thickn...

Nebulizers convert solutions or suspensions into aerosols with a particle size that can be inhaled into the lower respiratory tract. There are pneumatic jet nebulizers, ultrasonic nebulizers, and mesh nebulizers. Newer nebulizer designs are breath-enhanced, breath-actuated, or have aerosol-storage bags to minimize aerosol loss during exhalation. Nebulizers can be used with helium-oxygen mixture...

Aerosols have proven to be an effective form of drug delivery. Nevertheless, the development of devices as well as medical agents for aerosolization to treat mechanically ventilated newborns still presents a substantial challenge.1 Low tidal volumes and functional residual capacity, high breathing frequency, short aerosol particle residence time, and small airway diameters cause low aerosol dep...

The stable aerosol retrieval algorithm needs a prior assumption of lidar ratio (the extinction-to-backscatter ratio), and the known aerosol type that is the prerequisite of the assumption, so how to identify the clouds from lidar profile is fundamental to acquire atmospheric optical parameter. CALIPSO is a space-borne lidar and it can observe the aerosol characteristic, but can not penetrate th...

Atmospheric aerosols play very important roles in climate change and air particulate pollution. Due to their highly variable optical and physical properties as well as to short atmospheric lifetimes and large spatial and temporal gradients, the aerosol impact on climate models and air pollution is really a complex task. Lidars based on elastic scattering have been largely used to measure aeroso...

We investigated the large-scale connection between African aerosol and precipitation in the West African Monsoon (WAM) region using 8-year (2000–2007) monthly and daily Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol products (aerosol optical depth, fine mode fraction) and Tropical Rainfall Measuring Mission (TRMM) precipitation and rain type. These high-quality data further confi...

[1] The aerosol water content and volumetric growth factors of fine particulate matter were measured during July–August 2001 and January–June 2002 in an urban park about 6 km from downtown Pittsburgh, Pennsylvania. Most of the aerosol during the study was transported to the region from other areas, and its composition and concentration were characteristic of the regional particulate matter in t...

Humid conditions are expected in the containment during severe LWR accidents. In these conditions steam can condense on the containment structures and on existing aerosol particles or new particles may be formed by water vapor nucleation. In this paper the relative importance of each of these phenomena is evaluated. A mechanistic approach (NAUA-HYGRDS code) by solving the aerosol General Dynami...
