The phrase "a fixed depth and" is correct and usable in written English.
It can be used when describing a specific measurement or characteristic that is constant or unchanging, often in technical or scientific contexts.
Example: "The tank was designed to hold water at a fixed depth and maintain a stable environment for the aquatic life inside."
Alternatives: "a constant depth and" or "an unchanging depth and".
Over the course of the year, the ground temperature only varies slightly at a fixed depth and during the hot summer months when temperature in Muscat can rise to 47 °C (Directorate General of Meteorology, Oman, PACA) the subsurface temperature is significantly lower.
Proton therapy allows for high-dose radiation to be deposited very accurately at a fixed depth, and is particularly advantageous when the target lies close to critical normal tissue structure, such as in the treatment of the brain stem and in pediatric malignancies [ 22].
Is it then correct to use the calcium at the outermost shell to activate these mechanisms or one should use a fixed depth (e.g. 0.1 micrometre) and find the corresponding shell for each segment and use the calcium accumulated in that shell as the activating calcium and as the calcium transient generated in the cell?
Solute transport is described by assuming complete mixing of the element input within one homogeneous soil compartment with a constant density and a fixed depth (representing the root zone).
Analysis suggests that the duration of the noneroding portion of the ballistic event is neither governed by a fixed time, nor by a fixed depth of penetration, but rather by a fixed, permissible level of deformation in the penetrator.
Consider the signals in (18), and assume that the object is scanned at a fixed depth r = d k across all possible azimuths and elevations such that the object is still within the beam.
The main shaft is aligned parallel to the wave crests and submerged at a fixed depth.
In Figs. 10 and 11, a wider recess width has a higher drive current and lower resistance under a fixed depth of 62 nm.
In fact, newborns are believed to have a fixed depth of focus (Salapatek, Bechtold, & Bushnell, 1976), and in many cases, they even present some degree of astigmatism (Atkinson, 2000).
It is generally considered that the vertical stress is close to the overburden pressure and changes little with position for a fixed depth.
Failure to account for all related soil features on a landscape by ignoring features below a fixed depth (e.g., 2 m) can result in (i) inconsistent genetic interpretations and (ii) an inaccurate and disjointed depiction of soils on the landscape.
