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

SOIL SURFACE CRUST: ITS SIGNIFICANCE, TYPES AND MECHANICS OF FORMATION. A REVIEW [PDF]
Mesopotamia Journal of Agriculture, 2020 Most of the agricultural soils around the world suffer from increased soil degradation and erosion and reduce moisture conservation, which is the decisive factor in agricultural crop production, and among these problems is the phenomenon of Surface Soil ...

Soil–Water–Structure Interactions
Geotechnics, 2023 Interactions between soil, fluids (e.g., water), and structures are intrinsic to most geotechnical problems. However, these can be extremely complex and further understanding is needed in this field. Soil–water–structure interactions can be studied on many different scales (micro to macro) and perspectives (experimental, numerical, and theoretical). In

Géotechnique, 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 ...

Mycorrhizas and soil structure [PDF]
New 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 ...

Soil-Structure Interaction in Nonlinear Soil [PDF]
, 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.
