Boron deficiency responses in maize (Zea mays L.) roots
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

Measuring method for membrane penetration capacity of coarse-grained soil in triaxial tests
The membrane penetration effects displayed in the coarse-grained soil tests will distort the measurement of volume deformation of samples, thereby affecting the measuring accuracy of strength and deformation index.

A Constitutive Model Incorporating Mixed Soil Slurry for Interface [PDF]
In projects, mixed soil slurry between cut-off wall and coarse-grained soil always exists. It may influence on or change mechanical properties of interface between coarse-grained soil and structure.
