Most land trees, including redwoods, have xylem(木质部), or a system of small, tube-like cells. But without a pump, what makes water move through the xylem? Water evaporates (蒸发)from the leaves, pulling other water molecules(...

Water uptake regulation in peach trees with split‐root systems The water uptake of 3- to 4-year-old peach trees 'May-crest/ Prunus Damas' grown in an aerated nutrient solution was studied using a split-root system. Eac... T Simonneau,R Habib - 《Plant Cell & Environment》 被引量: ...
The system recently developed is a supercapacitor. This is a capacitor with two conducting sur-faces on which a charge of energy is stored. The energy it stores can be used later. The energy could power an LED light or a type of electronic. Researchers described their new model May 11, ...
Integrating data-driven ecological models in an expert-based decision support system for water management in the Du river basin (Vietnam) In this study, classification trees were combined with the Water Framework Directive (WFD)-Explorer, a modular toolbox that supports integrated water manag... ...

An erosion control system is disclosed which includes a seawall for protecting dunes or bluffs located adjacent a body of water. The seaward side of the seawall is notched or concave to direct incoming waves upwardly and outwardly, away from the base of the seawall and the bluff. The land...
Experimental data have been discussed on the effect of smoke blocking and temperature reduction by a water system in a reduced-scale tunnel, with and without forced longitudinal ventilation. Experimental data concerns temperature fields, extracted from thermocouple trees at different longitudinal positions ...
We acknowledge, however, that in addition to the observed enhanced flow rates near the cut, water stored in the sapwood of the trees21 could have partly mitigated transport constraints during the day. The results of this experiment suggest a considerable over-capacity in the conduit system of ...
