A fourth strategy uses source apportionment analysis or "receptor modeling", a widely used technique that distinguishes emission sources, especially for PM, by apportionment using profiles and source impacts [ 27].
Biallelic polymorphism in the TPMT (thiopurine S-methyltransferase) gene, wt/wt (G/G), mut/mut (C/C), and wt/mut (G/C), were distinguished as emissions in green, red, and yellow, respectively; the colors were identified even by the naked eye.
To clearly distinguish the emission peaks from a single QD, we fabricated small mesa structures with size ranging from 200 to 700 nm and measured the μPL spectrum near 920 and 940 nm, where the density of QDs is relatively low.
The ratio of indeno(1,2,3-cd pyrene/[indeno(1,2,3-cd pyrene/[indeno(g,h,i)perylene] for the two biomass boilers was lower than those of the reference data for other burning devices, which can probably be used as an indicator to distinguish the emission of biomass boilers from that of industrial coal-fired boilers and residential stoves.
In the specific example of Fig. 2, top, one can distinguish the emission of S (from the surfactant) and of argon (from the gas in the measurement chamber) which may serve for normalization, and the emission of K+ and of Cs+.
And yet many accounting schemes do not distinguish between emissions for local consumption and emissions for export.
This may be due to the difficulty in designing studies that distinguish between emissions from road tunnels and emissions from general surrounding traffic. 1 2 Only one study has investigated the association between exposure to emissions from a road tunnel ventilation stack and health effects.
Due to the impossibility of distinguishing emissions from the different types of waste with direct measurements, models have to be developed.
We ruled out unspecific binding to the cells by previous blocking, so spider silk could be distinguished by fluorescence emission at the appropriate wavelength.
Additionally, both eqFP611 and GFP fluorescences can be easily distinguished by their emission spectra.
