Abstract The little layer of tree plantations provides primary nutrients for uptake, buffers changes in soil moisture, and habitat substrate to epigeic fauna. However, this eucalypt is often removed reduce fuel load during the fire season Brazilian savanna (Cerrado). Therefore, it necessary quantify effects litter dynamics on function these plantations, key nutrient cycling processes fauna dive...

Atmospheric pollution critically affects forest ecosystems around the world by directly impacting the assimilation apparatus of trees and indirectly by altering soil conditions, which subsequently also leads to changes in carbon cycling. To evaluate the extent of the physiological effect of moderate level sulfate and reactive nitrogen acidic deposition, we performed a retrospective dendrochrono...

The study on the diameter and volume increment of black locust (Robinia pseudoacacia L.) stand (age 10-27 years, yield class II) have shown that in comparison to periodic annual breast height tree I, trees II reached 83.3%, while III only 43.9. same relations for were found 59.0% 24.5%, respectively. mean values whole close those II. According distribution between 10 27 years age, 50% 2.00 and1...

The vertical distribution of the cross-sectional area increment lower trunk in aged Sugi (Cryptomeria japonica) trees was analyzed using annual ring data from disks. We collected three approximately 90-year-old mature plantations under different density management and old-growth stands 160 years or more. Of nine sample thinning experiment plots, only had significantly higher increments at a rel...

Self-priming pumps, as important two-phase fluid machinery, are widely used in disaster relief and emergency fields. The flow characteristics of the air–liquid play an essential role self-priming pump performance. However, traditional simulation employed single-diameter bubbles for analysis, which cannot reflect internal field characteristics. Therefore, this article, Population Balance Model (...

BACKGROUND Arterial diameter and intima-media thickness (IMT) enlargement may each be related to the atherosclerotic process. Their separate or combined enlargement may indicate different arterial phenotypes with different atherosclerosis risk. METHODS We investigated cross-sectional (baseline 1987-89: n = 7956) and prospective (median follow-up = 5.9 years: n = 4845) associations between bas...
