Mycorrhizas and soil structure [PDF]

open access: yesNew Phytologist, 2006
SummaryIn addition to their well‐recognized roles in plant nutrition and communities, mycorrhizas can influence the key ecosystem process of soil aggregation. Here we review the contribution of mycorrhizas, mostly focused on arbuscular mycorrhizal fungi (AMF), to soil structure at various hierarchical levels: plant community; individual root; and the ...

Effect of soil permeability on soil–structure and structure–soil–structure interaction of low-rise structures

open access: yesGéotechnique, 2022
Earthquake-induced soil liquefaction can generate excessive damage to building structures due to significant reduction in soil effective stress. With increasing urbanisation and population growth, the performance of closely spaced buildings, such as those in towns and cities, is of greater concern where structure–soil–structure interaction (SSSI) may ...

Identification of Group II Intron RmInt1 Binding Sites in a Bacterial Genome

open access: yesFrontiers in Molecular Biosciences, 2022
RmInt1 is a group II intron encoding a reverse transcriptase protein (IEP) lacking the C-terminal endonuclease domain. RmInt1 is an efficient mobile retroelement that predominantly reverse splices into the transient single-stranded DNA at the template ...

Comparison of Fuzzy and ANN models performance for monthly flow forecast using short time data [PDF]

open access: yesعلوم و مهندسی آبیاری, 2010
Regarding the bottom outlet gates, the optimal hydraulic design to ensure non-occurrence of destructive vibrations is very important. Forces inserted into the gates due to the flow with high hydrostatic pressure under the gates may cause creation of ...

Soil-Structure Interaction in Nonlinear Soil [PDF]

open access: yes, 2009
A two-dimensional (2-D) model of a building supported by a semi-circular flexible foundation embedded in nonlinear soil is analyzed. The building, the foundation, and the soil have different physical properties. The model is excited by a half-sine SH wave pulse, which travels toward the foundation.
