Here, the incident and scattered waves are related via the transition matrix, or simply “T-matrix,” which depends only on the properties of a particle and the choice of coordinate system, but not on the incident wave. The T-matrix method is used in a variety of situations of interest ...
Hence the choice of sampling position(s) is a key factor in any determination of fire effluents, and the position(s) chosen will often depend on the required end use of the data. For example fundamental combustion studies may require sampling directly from a flame, with toxicity/life threat ...
Bioaerosols in public transportation systems raise critical environmental concerns, seriously threatening passenger health and safety. In this study, we investigate the spread characteristics of bioaerosols in a standard type-B subway compartment using b
A laboratory micro X-ray fluorescence spectrometer based on polycapillary X-ray optics (PXRO) was used to carry out the quantitative X-ray fluorescence analysis of single aerosol particles with smaller size than that of focal spot of PXRO. The minimum detection limits measured with the thin-fil...
Different degrees of spatial heterogeneity of the AOD were found, which were indexed by Moran's I index giving values of 0.940, 0.715, and 0.680 in BTH, YRD, and PRD, respectively. For the spatial heterogeneity, geographically weighted regression (GWR) was employed to carry out a spatial ...
By separating the impacts of cloud and aerosol on the POAI, it is found that clouds are responsible for the most reduction of POAI in the SC, while aerosols and clouds are equally important for the NI region. The frequent occurrences of low and middle level clouds with high optical depth...
In these trials, the patients on budesonide and formoterol fumarate dihydrate had a mean age of 38 years and were predominantly Caucasian (82%). The incidence of common adverse events in Table 2 below is based upon pooled data from three 12-week, double-blind, placebo-controlled clinical ...
dosed either daily or on alternate days, could increase the likelihood of HPA suppression compared to a therapeutic dose of either one alone. Therefore,Azmacort (triamcinolone acetonide (inhalation aerosol))Inhalation Aerosol should be used with caution in patients already receiving prednisone treatment...
A complete capture (i.e., 100% efficiency) of the large aerosols in a challenging feed stream with polydispersed aerosol sizes provides a good indication on the formation of the cake layer. When the efficiency of the reference aerosol size reaches 100%, cake or surface filtration would have...
Although much is known about atmospheric aerosols, in general, the specific composition is a matter of much debate. This is especially so because of its dependence on the source type, and its chemical reactivity and age.12 The typical composition of an aerosol particle is shown in Figure 1, ...
