As soil solutions pass through forested mineral soils, the chemical and structural compositions of dissolved organic carbon (DOC) can alter substantially due to interactions with soil particle surfaces. Typically, adsorption processes dominate in mineral soils and the resulting concentration of DOC is reduced substantially. We studied changes in the molecular and structural compositions of DOC during...
The recent emphasis on rough energy landscapes for protein folding reactions by theoreticians, and the many observations of complex folding kinetics by experimentalists provide a rationale for a brief literature survey of various empirical approaches for validating the underlying mechanisms. The determination of the folding mechanism is a key step in defining the energy surface on which the folding...
To develop a specified method to estimate humus contents in natural fresh waters, the colour of humic water samples was measured for fractionated and original water samples by spectrophotometry. The results were compared to those of the comparator method and they support the use of 400 or 465<space>nm. The combination of absorbance and fluorescence measurements proved to be the more reliable...
