Compatible measurements of volumetric soil water content using a neutron probe and Diviner 2000 after field calibration. [PDF]

, 2006
Field calibrations for a neutron probe and a capacitance sensor (Diviner 2000) for measuring the soil water content of a shrinking–swelling clay soil were substantially different from commonly used default values. Using our field calibrations, the two

Experimental study on water transfer of soil-rock mixtures under freezing action

Yantu gongcheng xuebao
The frost-heaving failure of earth-rock dam slopes is mainly caused by the combined action of sand and gravel cushion, frost heaving of dam fills and water migration.

Estimation of Soil Hydraulic Parameters with Measurment of Soil Water Content, Pressure Head or Measurment the Simultaneously by Inverse Method [PDF]

علوم و مهندسی آبیاری, 2014
Most processes of soil and water in the field occur in unsaturated conditions.In the field, It’s possible to estimate soil hydraulic properties by measurement of soil water content and soil water pressure head in different times, using inverse method. In

Soil Water Content at Planting Affects Determining Agricultural Drought for Rainfed Spring Wheat

Atmosphere, 2023
Agricultural drought often refers to water deficit in soil caused by a shortage of precipitation during a specific period in crop growing season, thus leading to final crop production failure. However, soil water content during planting may be related to

Improving wheat yield and water use efficiency through soil water-guided furrow irrigation and hydraulic simulation

Agricultural Water Management
Despite the increasing adoption of precision irrigation technologies including drip and sprinkler systems, traditional methods such as furrow irrigation remain widely used among small-scale farmers due to their lower costs and simpler management ...

Vertical distribution of soil organic and inorganic carbon under different vegetation covers in two toposequences of the Liudaogou watershed on the Loess Plateau, China

, 2018
Understanding the carbon (C) cycle of the terrestrial ecosystem and estimating the C sequestration potential in soils are critical to evaluate ecosystem function and security.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Experimental Study on the Variation of Soil Dielectric Permittivity under the Influence of Soil Compaction and Water Content

Geofluids, 2022
The dielectric permittivity of common soils is mainly controlled by water content and porosity, while the latter is closely related to the characteristics of compaction.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...
