Estimation of vegetation water content using hyperspectral vegetation indices: a comparison of crop water indicators in response to water stress treatments for summer maize

open access: yesBMC Ecology, 2019
BackgroundVegetation water content is one of the important biophysical features of vegetation health, and its remote estimation can be utilized to real-timely monitor vegetation water stress. Here, we compared the responses of canopy water content (CWC),

Water content, not stiffness, dominates Brillouin spectroscopy measurements in hydrated materials [PDF]

open access: yesNature Methods, 2017
Brillouin microscopy measures compressibility, but is being increasingly used to assess stiffness of cells and tissues. Using hydrogels with tunable properties, we demonstrate that Brillouin microscopy is insensitive to stiffness of hydrated materials ...

Glacial varves at the distal slope of Pandivere-Neva ice-recessional formations in western Estonia [PDF]

open access: yesBulletin of the Geological Society of Finland, 2012
The distribution and varve thickness data of Late Weichselian varved clay were analyzed to describe the proglacial sedimentary environment, ice recession and water-level changes in the Baltic Ice Lake at the distal position of Pandivere–Neva (13.5–13.1 ...

Structure, Organization and Heterogeneity of Water-Containing Deep Eutectic Solvents [PDF]

open access: yes, 2022
The spectroscopy and structural dynamics of a deep eutectic mixture (KSCN/acetamide) with varying water content is investigated from 2D IR (with the C-N stretch vibration of the SCN$^-$ anions as the reporter) and THz spectroscopy. Molecular dynamics simulations correctly describe the non-trivial dependence of both spectroscopic signatures depending on

Age-related changes in local water and protein content of human eye lenses measured by Raman microspectroscopy [PDF]

open access: yes, 1991
The Raman microspectroscopic method was used to determine the local water and protein content in human lenses. In 18 lenses of varying age position-defined water/protein content measurements were carried out along the visual and the equatorial axis.\ud ...

Research on the Optimum Water Content of Detecting Soil Nitrogen Using Near Infrared Sensor

open access: yesSensors, 2017
Nitrogen is one of the important indexes to evaluate the physiological and biochemical properties of soil. The level of soil nitrogen content influences the nutrient levels of crops directly.

OsDOF11 Affects Nitrogen Metabolism by Sucrose Transport Signaling in Rice (Oryza sativa L.)

open access: yesFrontiers in Plant Science, 2021
Carbon and nitrogen antagonistically regulate multiple developmental processes. However, the molecular mechanism affecting nitrogen metabolism by sucrose transport remains poorly defined. Previously, we noted that Oryza sativa DNA BINDING WITH ONE FINGER
