The before Fig. (2a) and after Fig. (2b) UV exposure spectra are qualitatively similar, suggesting that the UV exposure does not degrade the lipid layer.
To remove all signatures that are not the result of exposure, the spectrum after 10 min of exposure, within each exposure series, was subtracted from all the other spectra.
The IRAS spectra were recorded in absorbance units (−log(R/ R0)), where R is the reflectance of the exposed sample and R0 is the reflectance of the sample before exposure (background spectrum).
Upon hexane exposure, a spectrum of putative transporters, including five transporters involved in bicarbonate transporting (Slr0041, Slr0043, Sll0834, Slr1512, Sll1734), two involved in cation transporting (Slr2131, Sll0672), two involved in Na+ and K+ transporting (Sll0689, Sll0493), one involved in mercuric transporting (Ssr2857), were up-regulated (Table 1).
While after Pb II) exposure the spectra showed the major peaks of Pb II) with 30.9, 14.2, 21.6 mass percent by replacing the peaks for K and Cl and decreased the mass percent of other elements (C, O, P).
However, through the magic of long exposure photography, a spectrum of colours is visible.
Amongst the risk factors for invasive fungal infections is exposure to broad spectrum antibiotics and fungal colonisation of mucosal surfaces.
Doppler Effect has then a small influence on the sound exposure; the receiver spectrum in the forward arc is shifted to higher frequencies where the sound absorption increases.
