Putting two water transport models to the test under wet and dry conditions [PDF]

, 2013
In order to improve fruit quality and quantity, accurate monitoring of the water status is necessary. The water status can be continuously predicted by using a mechanistic water transport and storage model (e.g. Steppe et al., 2006; 2008).

Parameter Variation in Planetary Ball Milling of Titanium Aluminide Powder in XHV‐Adequate Atmosphere

Advanced Engineering Materials, EarlyView.
This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

HYDRAULIC CIRCULATION PERFORMANCE OF A CURVILINEAR MARINA

Coastal Engineering Proceedings, 1980
An innovative coastal engineering concept has been developed to maximize the hydraulic circulation and water quality of dredged backshore harbors and boat basins. The concept represents a radical departure from the hydraulic design of existing artificial boat basins in that the basin geometry and entrance channel are primarily sized for hydraulic ...

Hydraulic conductivity of a dense prehydrated GCL: impact of free swell and swelling pressure [PDF]

, 2008
Exposure to liquids with high electrolyte concentrations or high cation valence present in landfill leachates can cause significant increases in hydraulic conductivity of clays due to a reduction in the thickness of the double layer.
