MACROMOLECULAR STRUCTURES OF HUMIC SUBSTANCES

open access: closedSoil Science, 1980
ABSTRACTWe investigated humic substances by surface pressure and viscosity measurements at different pHs and neutral salt concentrations to elucidate their macromolecular configurations. We observed that such configurations were not unique; they varied with the changes in the medium.

Clearance of macromolecular and particulate substances from the cerebrospinal fluid system of the rat

open access: closedJournal of Neurosurgery, 1979
✓ Arachnoid villi in the intracranial dural sinuses constitute the principal sites for absorption of proteins and particulates from the cerebrospinal fluid (CSF) system. Although arachnoid villi in the rat are morphologically less complex than those found in other mammals, their resistance to CSF outflow, as assessed by a graded series of constant flow

Characterization of Water-Soluble Macromolecular Substances in Cloud Water

open access: closedJournal of Atmospheric Chemistry, 2004
In this contribution we present to our knowledge the first investigations of macromolecular, often called humic-like substances (HULIS) in cloud water samples and compare them with water-soluble extracts from atmospheric PM2.5, soils and waters to study its possible origin.
