The phrase "a water gradient" is correct and usable in written English.
It can be used in contexts related to environmental science, hydrology, or any discussion involving the variation of water concentration or flow in a given area.
Example: "The study focused on the effects of a water gradient on local plant species and their growth patterns."
Alternatives: "a moisture gradient" or "a hydric gradient".
Instead of 'brain,' think 'network.' It seems to be that many higher organisms are internally networked in such a way that local changes," such as the way that roots respond to a water gradient, "cause very local responses which benefit the entire organism".
The model and the experimental results also confirmed that a water gradient (2 3%) still existed in the dried sample around the walls of the cells that are located at the centre of the tissue.
Recently, Baslow proposed that the NAA cycle itself might serve as a neuronal mechanism to remove large amounts of water generated during action potential development.[1], [5] To prevent swelling of neurons, this metabolic water has to be eliminated, which has been to occur energy driven and against a water gradient.
These pots would allow a water gradient to form in the pot; the upper roots would dry out first.
Since fatty acids and other lipids in human milk may interfere with cholesteryl ester separation [ 29], we included a water gradient (15% to 0% H2O, 16.5% to 19.4% reagent alcohol with acetonitrile in the first 5 min of the separation) before the isocratic gradient used for validation run 1.
However, the acronym HILIC was suggested to distinguish it from NP, as NP is typically performed with nonaqueous, non-water-miscible solvent buffers, while HILIC is performed with water-miscible solvents and elution is achieved by a water gradient [ 2, 9, 17, 18].
Cleavage from the resin and removal of protecting groups was effected by a mixture of trifluoroacetic acid (95%), triisopropylsilane (2.5%) and water (2.5%).Peptides were purified by reverse-phase liquid chromatography using a linear acetonitrile:water gradient and masses were verified by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry.
The mobile phase comprised a methanol to water gradient and 0.1% formic acid (which protonated the sample compounds).
Even if it's not a air temperature gradient, it's a water temperature gradient.
The injected peptides were trapped and desalted for 3 min at 100 µL/min and then separated in 6 min by an 8% 40% acetonitrile:water gradient at 40 µL/min.
This is accomplished by imparting a water concentration gradient through the polymer membrane, thereby increasing the back diffusion rate of water.
