The resulting total current is then proportional to the number concentration of the sampled particles over the collected size range.
Decantation removes these particles along with other fine particles, ultimately biasing the method to retain larger sized particles within the collected size range.
In addition, based on the chemical analysis of the collected size-fractioned particle samples, results indicated that the pellet addition did not increase the corrosion risk of the boiler.
A battery-powered eight-stage aerosol impactor (i.e. a Davis Rotating-drum Unit for Monitoring), mounted at the top of a 10 m meteorological tower in the burn zone, collected size- and time-resolved aerosol samples with 19.45 min resolution for 24 h during the burn.
A two-stage streaker sampler was exposed to collect size-fractionated aerosol samples in Genova.
With this purpose, detailed sampling surveys were performed to collect size distribution data at the steady state conditions of the cement grinding circuits at different plants.
Sampling methodology was developed to collect size-fractionated particulate matter from the smokestack of either a coal-fired or an oil-fired power plant.
Cancer registries should as a matter of routine collect size of breast cancers and the screening status to enable further monitoring of the impact of mammographic breast cancer screening.
Drops in the size range between OPC and LDDS were collected and sized by an off-line method.
Further, if browse occurred before an individual's size data was collected or size was otherwise unavailable, we used linear imputation (Gelman and Hill 2006) to estimate its size (412 instances of size imputation out of 1481 total size records).
