Uniform angle index
-
In this study, our overall goal is to characterize spatial attributes of neighborhood trees by applying the current techniques of nearest neighbor statistics. For a better understanding of structural units, we three structural units for each species analyses, such as mingling - index, mingling - dominance and dominance uniform angle index.

The results showed that (1) the dominant species in the three forest types had a species mingling degree ranging from medium to complete mixture; (2) the target trees were found to have a dominant height compared to their nearest neighbors; (3) the distribution patterns of trees in the stands varied from regular to clumped; and (4) the crowding index indicated a distribution density of trees from sparse to dense.

Aiming to describe spatial patterns, species mingling and dominance of species at fine spatial scales, we applied the quantitative analyses based on relationships of nearest neighboring trees. In two 1- ha plot of tropical evergreen forest stands in Babe National park, northern Vietnam, all tree individuals with diameter at breast height-DBH ≥ 2.5 cm were mapped and their characteristics (i.e., DBH and species) were recorded.

The spatial structural parameters offer direct information and valuable about spatial structure forest stand. Those information can be used in thinning of sustainable forest management, modelling and restoration.

Application of waste bulk moulded composite (BMC) as a filler for isotactic polypropylene composites
The aim of this study was to produce isotactic polypropylene based composites filled with waste thermosetting bulk moulded composite (BMC). The influence of BMC waste addition (5, 10, 20 wt%) on composites structure and properties was investigated. Moreover, additional studies of chemical treatment of the filler were prepared. Modification of BMC waste by calcium stearate (CaSt) powder allows to assess the possibility of the production of composites with better dispersion of the filler and more uniform properties.

The effects of micronization methods, mechanical and jet millings, on the physico-chemical properties of mushroom (Lentinus edodes) powder were investigated in contrast to shear pulverization. The powders of dried mushroom cap and stipe were prepared to obtain six powders. Compared to shear pulverization, mechanical and jet millings effectively reduced particle size and brought about a narrow and uniform particle size distribution.
