In order to define a statistical method of the analysis of mass heterogeneous structures, we have formulated stochastic and dynamic mass distribution in these structures. The expressions derived were used to calculate some of the basic characteristics of the heterogeneous structures at room and high

The lignin distribution between the middle lamella and the cell wall of spruce fibers has been determined by a new technique based on a mercurization of the lignin and a concomitant determination of mercury by the SEM-EDXA technique. The ratio of lignin in the middle lamella at the cell comers to th
A lignin-carbohydrate material from black spruce (Picea mariana) was treated with a hemicellulase mixture. The carbohydrates in the remaining material were studied by the following methods, a) Treatment with 0.1 M NaOH in the presence of sodium borohydride followed by selective hydrolysis of the fur
