Coordination of Foliar and Wood Anatomical Traits Contributes to Tropical Tree Distributions and Productivity along the Malay-Thai Peninsula [PDF]
, 2009 Drought is a critical factor in plant species distributions. Much research points to its relevance even in moist tropical regions. Recent studies have begun to elucidate mechanisms underlying the distributions of tropical tree species with respect to ...

IOP Conference Series: Earth and Environmental Science, 2019 An experimental test circuit was built with submerged nozzle with diameter 1.2 mm and inlet pressure 200 bar. Several specimens of different cavitation resistant materials used for hydraulic turbines (e.g. 13Cr4Ni) and coatings (e.g. tungsten and chromium carbides) were tested.

Archives of Foundry Engineering, 2016 The main reason of a cavitational destruction is the mechanical action of cavitation pulses onto the material’s surface. The course of cavitation destruction process is very complex and depends on the physicochemical and structural features of a material.

Cavitation-Resistant Coatings for Hydropower Turbines [PDF]
, 2011 Abstract : Operating hydropower turbines to obtain the ultimate power output often results in cavitation (the rapid formation and collapse of vapor pockets in a flowing liquid in regions of very low pressure) in the turbine area. The level of cavitation typically destroys organic coatings in a relatively short time.

Xylem Hydraulics of Two Temperate Tree Species with Contrasting Growth Rates
PlantsHydraulic functionality is crucial for tree productivity and stress tolerance. According to the theory of the fast–slow economics spectrum, the adaptive strategies of different tree species diverge along a spectrum defined by coordination and trade-offs ...

Stem hydraulic capacitance decreases with drought stress : implications for modelling tree hydraulics in the Mediterranean oak Quercus ilex [PDF]
, 2017 Hydraulic modelling is a primary tool to predict plant performance in future drier scenarios. However, as most tree models are validated under non-stress conditions they may fail when water becomes limiting.

Effects of Ce, Sm and Yb on cavitation erosion of NAB alloy in 3.5% NaCl solution
Ultrasonics Sonochemistry, 2022 The influences of Ce, Sm and Yb on cavitation erosion of NAB alloy in 3.5% NaCl solution are evaluated using mass loss, SEM, 3D morphology and Tafel plot, respectively. The results show that the addition of Ce or Sm or Yb enhances the mechanical property

Causes of Quality Loss of Cut Flowers - A Critical Analysis of Post-Harvest Treatments [PDF]
, 2009 Temperature is one of the most important factors in the postharvest phase to control quality losses, yet temperature is still poorly managed, partly because its effects are not always understood well.

Numerical simulation of grain-size effects on creep crack growth by means of grain elements [PDF]
, 1998 The effect of grain size on creep crack growth is investigated by means of a numerical technique in which the actual crack growth process is simulated in a discrete manner by grain elements and grain boundary elements.
