Effects of Wetting-drying Cycles on Bulk Density and Saturated Hydraulic Conductivity of Soils

Guan'gai paishui xuebao, 2022
【Objective】 Changes in density and hydraulic conductivity of soil not only modulate subsurface hydrological processes but also affect root growth and root uptake of water and nutrients from soil.

Physical properties of kernels from modern maize hybrids used in Croatia [PDF]

Journal of Central European Agriculture, 2020
The physical properties of maize are a result of kernel structure, they indicate chemical properties of the kernel, and hence, its nutritive value. This research aimed to explore the physical traits of kernels of 80 commercial maize hybrids from nine ...

S-wave superconductivity near a surface

, 2003
We study the superconducting order parameter near a surface with the Bogoliubov-de Gennes formalism. For definiteness we use the attractive Hubbard model.

Soil compaction caused by 450C Timber Jack wheeled skidder (Shefarood forest, northern Iran)

Journal of Forest Science, 2007
In forest harvesting operations usually after using skidding machinery (skidders), traces of soil damage in the form of soil compaction and wheel and logs ruts can be seen in the forest soil. Soil bulk density, which represents soil compaction, decreases

Bulk modulus-density systematics [PDF]

Journal of Geophysical Research, 1969
The elastic constants of crystals show a general tendency to increase as the mean molar volume 〈V〉 = 〈M〉/ρ decreases. The role of other factors, such as cation radius, crystal field effects, and anion-cation coordination, can now be discussed with available elastic constant data.

Bulk Density Protocol [PDF]

, 2003
The purpose of this resource is to measure the bulk density of each horizon in a soil profile. In the field, students collect three soil samples from each horizon in a soil profile using a container with a measured volume.

Fluctuations of water near extended hydrophobic and hydrophilic surfaces

, 2009
We use molecular dynamics simulations of the SPC-E model of liquid water to derive probability distributions for water density fluctuations in probe volumes of different shapes and sizes, both in the bulk as well as near hydrophobic and hydrophilic ...

Low density instability in a nuclear Fermi liquid drop

, 1998
The instability of a Fermi-liquid drop with respect to bulk density distortions is considered. It is shown that the presence of the surface strongly reduces the growth rate of the bulk instability of the finite Fermi-liquid drop because of the anomalous ...
