Chemical and spectroscopic characteristics of humic acids

2013
To characterise soil humic acids (HAs) extracted from Spanish marshes formed under different vegetation types (Spartina maritima (GSp), Juncus maritimus (GJc), Phragmites australis (GPh), and Scirpus maritimus (VSc)), soil depths (0-20, 20-40 and 40-60 cm), physiographic position (low and high marshes), wetland types (salt marshes and lagoons) and ...

Proton MR spectroscopic characteristics of pediatric pilocytic astrocytomas.

AJNR. American journal of neuroradiology, 1998
We report the common characteristics of juvenile pilocytic astrocytomas revealed by proton MR spectroscopy.Eight children with pilocytic astrocytomas were studied with proton MR spectroscopy. The selected sampling volume was approximately 4 cm3, obtained from solid tumor.

Spectroscopic characteristics of metalloporphyrins used in photodynamic therapy.

Oftalmologia (Bucharest, Romania : 1990), 2004
The photodynamic therapy (PDT) became more and more widely used in the treatment of different malignant tumors. For present studies, porphyrins and haematoporphyrin derivatives, in the conditions of N2 laser radiation, were chosen because their strong absorption along a large spectral range; this makes possible the excitation of their fluorescence at ...
