The water content dynamics in the upper soil surface during evaporation is a key element in land–atmosphere exchanges. Previous experimental studies have suggested that the soil water content increases at the depth of 5 to 15 cm below the soil surface duri ...
High-porosity dunite channels are important pathways for melt migration in the mantle. To better understand the first order characteristics of the high-porosity melt channel and its associated peridotite lithologies in an upwelling mantle, we conducted hig ...
In this technical note we compare silica gel grains and quartz sand as sediment media for vegetation root growth in laboratory experiments for ecohydrology and ecohydraulics. Silica gel grains become quite transparent when saturated with water. This would ...
Semi-impregnated fabrics, or semipregs, are fabrics alternating dry and resin impregnated areas along the fibre bed surface. Due to their increased initial through thickness permeability to gas flow, these could constitute an alternative to prepreg in the ...
Increased sediment production resulting from the erosion of unprotected soil in a catchment may result in severe changes in the morphodynamics and hydrodynamics of mountain rivers. Sediment overfeeding can lead to the degradation of salmonids' spawning sit ...
Two-step sintering of nanocrystalline zirconia powder stabilized with 8 mol% yttria resulted in remarkable enhancement of the electrical conductivity and significant suppression of the accelerated grain growth. The electrical conductivity of the nearly ful ...
Granular surfaces subjected to forces due to rolling wheels develop ripples above a critical speed. The resulting pattern, known as washboard or corrugated road, is common on dry unpaved roads. We investigated this phenomenon theoretically and experimental ...
The use of low-energy femtosecond laser beam combined with chemical etching has been proven to be an efficient method to fabricate three-dimensional structures in fused silica. For high-volume application, this technology – like other serial processes – su ...
What is the influence of sand grain shapes on an hourglass accuracy, and how does it affect the jamming probability? We study such a question using numerical simulation and our recently introduced spheropolyhedral particles. Spheropolyhedra constitute a ve ...
Laboratory tests and inverse methods are used for the determination of the thermophysical properties of a CuCrZr alloy. The solidification path (temperature versus solid fraction curve) is determined using the Single Pan Thermal Analysis (SPTA) technique d ...
