White piedra is a superficial fungal infection of the hair. Several species of fungus that live in soil or dirty water can cause it. Piedra is the Spanish word for stone. White piedra appears as ...

Molecular fluorescence is typically reduced or “quenched” by dissolved oxygen present ... resulting in a more accurate determination of the static quenching constant. Absorption spectra obtained at ...

THE fluorescence spectrum of anisole in the vapour state has been developed following the technique of Bass and Sponer 1. The vapour was contained in a cell fitted with quartz windows and the ...

White matter hyperintensities (WMH) are the most prevalent imaging marker in cerebrovascular ... We used a completely data-driven approach to evaluate the differences in the power spectra between the ...

In this study, we quantitatively investigated spectral-spatial features of multi-photon excitation fluorescence in normal and diseased livers. For morphometrics of multi-photon excitation spectra, we ...
