The phrase "a defined preparation" is correct and usable in written English.
It can be used when referring to a specific and clearly outlined process or method of preparing something.
Example: "Before starting the experiment, we need to ensure that we have a defined preparation for all the materials involved."
Alternatives: "a specified preparation" or "a detailed preparation".
To conclusively validate the role of A β oligomers, we treated non-transgenic cultures with defined preparation of A β42 oligomers at sublethal concentrations.
Electropolymerisation is a technique for the tightly controlled and defined preparation of polymeric structures.
In recent years defined preparation of thin films has become highly desired since many technological applications or fundamental studies depend on the reliable and controlled fabrication of organic, inorganic, or metallic thin films.
In this study we developed a reliable, rapid real-time PCR assay that detects a 225 bp segment of the hexon gene of both the HAdV-14p and -14a genomes on the J.B.A.I.D.S. and LightCycler 2.0 thermocycler platforms, and validated the assay using both defined preparations of isolated virus and original clinical throat swabs from recognized HAdV-14 outbreaks in military populations.
In conclusion, further research is needed to determine the optimal approach to transition preparation, with a focus on defining preparation activities that are important determinants of young adult diabetes self-care success.
The Convention provides that "a preparation is subject to the same measures of control as the psychotropic substance which it contains," and defines "preparation" as "any solution or mixture, in whatever physical state, containing one or more psychotropic substances". See 32 U. S. T., at 546, Art.
Embossed tablets or identified capsules are cross-referenced in the Physician's Desk Reference (PDR) and are traceable to a defined, standardized drug preparation manufactured to rigid FDA standards.
A major problem with the study of glycogen as a regulatory molecule is that it does not have a defined structure, so different preparations may behave quite differently.
The typical workflow (Fig. 1b) starts with the preparation of a defined suspension of microorganisms followed by the ARTP treatment.
The second objective of this study was therefore to compare the response of PMNs to two chitosan preparations of a defined DDA, namely 80 M chitosan and 95% deacetylated (95 M) chitosan.
