In this work, a novel thinner derived from natural botany Chinese Larch Tree was obtained by combination lignin with phenol using H2O2 as oxidant and the acting efficiency of lignosulfonate in the drilling fluids is greatly enhanced after oxidation with H2O2. Both the chemical structure and the adsorptive ability of the oxidation...

Proactive silviculture treatments (e.g., thinning) may increase C sequestration contributing to climate change mitigation, although, there are still questions about this effect in Mediterranean pine forests. The aim of research was quantify the storage biomass and soil organic carbon Pinus forests along a climatic gradient from North South Iberian Peninsula. Nine experimental spp trials were se...

Self-thinning is a dynamic equilibrium between forest growth and mortality at full site occupancy. Parameters of the self-thinning lines are often confounded by differences across various stand and site conditions. For overcoming the problem of hierarchical and repeated measures, we used hierarchical Bayesian method to estimate the self-thinning line. The results showed that the self-thinning l...

This article is a comprehensive survey of thinning methodologies. It discusses the wide range of thinning algorithms, including iterative deletion of pixels and nonpixel-based methods, whereas skeletonization algorithms based on medial axis and other distance transforms will be the subject matter of a subsequent study. This self-contained paper begins with an overview of the iterative thinning ...

It remains unclear if changes of the cerebral cortex occur gradually from childhood to adulthood, or if adolescence marks a differential period of cortical development. In the current study of 90 healthy volunteers aged 5-32years (48 females, 85 right handed) with 180 scans (2 scans for each participant with ~4year gaps), thinning of overall mean thickness and across the four major cortical lob...
