Article Synopsis
- The study focused on pure and mixed plantations of larch and birch in the Saihanba area, analyzing how tree species, stand density, and tree size impact larch productivity.
- A total of 668 tree core samples were taken to assess factors affecting larch growth, revealing that competition and tree dimensions significantly influenced its basal area increment.
- Results indicated that birch positively impacts larch growth in denser mixed forests, while lower density mixed plantations showed reduced productivity compared to pure ones due to insufficient interaction between species.
Article Synopsis
- Litter decomposition is crucial for nutrient cycling in forest ecosystems, and a study in Saihanba, China examined how different forest types influence this process.
- The results revealed that pure L forests had slower decomposition rates compared to mixed forests, with mixed litter (LBQ) showing the fastest decomposition.
- Nutrient contents changed consistently across all treatments, with N and P increasing while C and K decreased, and enzyme activities related to decomposition varied, showing a positive correlation with catalase, urease, and acid phosphatase, but a negative correlation with sucrase.
Fennel-like nanoaggregates based on polysaccharide derivatives and their application in drug delivery.

January 2014
Biodegradable polymeric nanoparticles, which hold hierarchical morphologies, are of importance for controlled drug delivery. In this work, nanoparticles with fennel-like morphology were prepared from graft copolymers of hydroxyethylcellulose and poly(p-dioxane). The effect of microstructure parameters on the morphological transition of the nano-aggregates was studied and the nanoparticles were investigated as a carrier of hydrophobic drug.
