Microbial Contribution to Soiling and Its Impact on Photovoltaic Module Soiling in Arid Zones of the Atacama Desert

open access: yesAdvanced Sustainable Systems, EarlyView.
Microorganisms colonizing photovoltaic surfaces in the Atacama desert form biofilms that enhance particle adhesion and reduce energy yield. This study identifies UV‐resistant bacteria and carotenoid‐producing strains that interfere with PV performance.

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields

open access: yesAdvanced Science, EarlyView.
Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

Centrifuge modeling of the behaviour of helical piles in cohesive soils from installation and axial loading

open access: yesSoils and Foundations, 2022
Centrifuge modeling offers a viable tool for research in the soil-pile interaction, but this technique has not been used for helical piles in cohesive soils.

Fluid - Structure - Soil Interaction of Cylindrical Liquid Storage Tank Subjected to Horizontal Earthquake Loading [PDF]

open access: yes, 2019
Shallow founded tanks are strategic structures used to store a variety of kind of liquids. The fluid develops hydrodynamic effect on solid domain of container during an earthquake. This paper provides the theoretical background for numerical model on

Mechanical Properties of Soil-cement Composites Made with Cohesive or Non-Cohesive Soil

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
The paper discusses results of mechanical and technological tests of soil-cement composites made with cohesive or non-cohesive soil. The compositions of the soil-cement mixtures analysed differed in terms of their cement paste volume fractions and water-cement ratios.

MGM as a Large‐Scale Pretrained Foundation Model for Microbiome Analyses in Diverse Contexts

open access: yesAdvanced Science, EarlyView.
We present the Microbial General Model (MGM), a transformer‐based foundation model pretrained on over 260,000 microbiome samples. MGM learns contextualized microbial representations via self‐supervised language modeling, enabling robust transfer learning, cross‐regional generalization, keystone taxa discovery, and prompt‐guided generation of realistic,

Laboratory study on the effects of hydraulic and granulometric parameters on the response of granular soil to internal erosion [PDF]

open access: yes, 2019
Erosion is a major environmental problem to agricultural land as well as to civil engineering infrastructures. Rainwater infiltration into granular soils can lead to the migration of fine particles by suffusion.

Use of rare earth oxides as tracers to identify sediment source areas for agricultural hillslopes [PDF]

open access: yes, 2010
Understanding sediment sources is essential to enable more effective targeting of in-field mitigation approaches to reduce diffuse pollution from agricultural land.

Studies on soil cohesion (Part 1) theory of cohesion in ideal soil [PDF]

open access: yesSoil Science and Plant Nutrition, 1956
Abstract 1. Historical. Theory of an ideal soil due to capillary films was first studied by W. B. Haines (1925),1) and this was corrected and developed by R. A. Fisher (1926). 2)

Pile Aging in Cohesive Soils [PDF]

open access: yesJournal of Geotechnical and Geoenvironmental Engineering, 2013
AbstractThis paper presents the results of a field investigation into pile aging in soft clay that was conducted over a period of 10 years. Static load tests were conducted after the excess pore pressure generated by the installation of 6-m-long, driven concrete piles were fully equalized.
