Basal density
웹The basal area of a stand of trees is the sum of the cross-sectional surface areas of each live tree, measured at DBH, and reported on a per unit area basis. Basal area is a measure of tree density, and widely used in forestry, wildlife, and other natural resource management professions. To calculate basal area, assume that a tree is cut off at 4.5 ft above ground … 웹2024년 7월 20일 · Corneal sub-basal inflammatory cell density was significantly higher in SS patients compared with control subjects (p < 0.0001). Furthermore, the mean corneal superficial epithelial cell density and area, inflammatory cell density, corneal sub-basal nerve fiber density, and morphological abnormality of nerve fibers, were improved with topical …

웹2024년 11월 22일 · Gravity-dependent atelectasis occurs due to a combination of reduced alveolar volume and increased perfusion. Due to gravity, it usually has a dependent and subpleural distribution. It is very commonly seen in the posterior lung bases on CT, particularly in elderly individuals. In normal lung, gravity gradients exist in end-inspiration between ... 웹2024년 4월 12일 · Three colour and depth (RGB-D) devices were compared, to assess the effect of depth image misalignment, resulting from simultaneous localisation and mapping (SLAM) error, due to forest structure complexity. Urban parkland (S1) was used to assess stem density, and understory vegetation (≤1.3 m) was assessed in native woodland …
웹However, their performance is bottlenecked by the inertness of the basal plane. The present study demonstrates alloying as a viable route to address such limitation. A machine learning workflow based on density functional theory (DFT) calculations has been established to predict the HER activity and stability for a series of 2D cation-mixed TMDC alloys of various … 웹2024년 12월 21일 · Pyroclastic density currents (PDCs) are a significant volcanic hazard. However, their dominant transport mechanisms remain poorly understood, in part because of the large variability of PDC types and deposits.
