The phrase "a tool for defining" is correct and usable in written English.
You can use it when discussing instruments or methods that help clarify or establish definitions in various contexts, such as education, technology, or research.
Example: "The glossary serves as a tool for defining key terms used throughout the report."
Alternatives: "an instrument for clarifying" or "a means of establishing".
Metabolomics is therefore a tool for defining observable molecular characteristics (or molecular phenotypes) that are associated with metabolism.
We argue here that the classical Configural Superiority Effect (CSE, described in Pomerantz, Sager and Stoever3) can be used to make progress in this context, as it may serve as a tool for defining Gestalts operationally, allowing us to assess their neural correlates and their generality (a critical step forward towards a theory of perceptual organization).
We therefore suggest the use of SRS for the selection of refractory RA patients who may be treated with biological therapies but not as a tool for defining treatment in secondary SS.
As a tool for defining sepsis and selecting patients for enrollment in clinical sepsis trials, SIRS is nonspecific, and for ≥ 3 fulfilled criteria it lacks sensitivity.
Histopathological scoring of adrenocortical tumours provide a tool for defining malignancy, survival and the risk of metastases as shown by van't Sant et al (2007).
As a tool for defining the role of Shc adaptor in TRK-T3 signal transduction we used the ShcY317F mutant of the 52 kDa Shc isoform, in which the tyrosine 317 has been changed to phenylalanine.
All these advantages make experimental design a powerful tool for defining an optimized recombinant protein production process.
Segmentation is also a powerful tool for defining spatial dependency where, by this tool, an image can be divided into homogenous regions.
Therefore, this index represents a powerful tool for defining more appropriate façade solutions for exposures that result in atmospheric water penetration.
Comparative analysis of E12.5 and E14.5 autopods revealed proteoglycan-rich fibrils maintain connections between the epidermis and the underlying tendon and cartilage, indicating a role for the ECM during musculoskeletal assembly and demonstrating that our method can be a powerful tool for defining the spatiotemporal distribution of the ECM during embryogenesis.
In light of the observation that iPS cell derivation takes place under the same culture conditions used for ES cells [20], we hypothesized that these human feeder cells could offer a stable tool for defining molecular hallmarks during conversion of differentiated somatic cells to the pluripotent state.
