Above- and below-ground competition in high and low irradiance: tree seedling responses to a competing liana Byttneria grandifolia [PDF]
: In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of above- and below-ground resources and differ between tree species.

Computational analysis of helicopter main rotor blades in ground effect [PDF]
Numerical investigation of an isolated representative helicopter main rotor has been performed in ANSYS FLUENT 16.2. In general, flow field around the rotor is unsteady, three-dimensional, complex and vortical.

ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Measurements of a rotor flow in ground effect and visualization of the brown-out phenomenon [PDF]
Quantitative and qualitative results of a series of experiments conducted on a rotor in ground effect at low forward speeds are presented. The velocity over a wide area of the ground effect wake was measured using Particle Image Velocimetry (PIV), and ...

Investigation of Heaving-pitching Airfoil in Ground Proximity using Large Eddy Simulations [PDF]
This study examines the aerodynamics of a wing-in-ground (WIG) airfoil subjected to heaving (plunging) & pitching motion, specifically examining the distinctions in flow between transitional and turbulent states, which are essential for assessing its ...
