The phrase "at three different steps" is correct and usable in written English.
It can be used when describing a process or procedure that involves multiple stages or phases.
Example: "The project will be completed at three different steps: planning, execution, and evaluation."
Alternatives: "in three distinct stages" or "across three separate phases".
Debonding propagation in specimen A-25-0-0 A-25-0-0 A-25-0-0 A-25-0-0ferent steps of the fisillustrated simulation in four 11.
The depositions of thin films were done at two different steps and conditions: TiO2 thin film was deposited first using 120 W for 40 min time deposition using radio frequency (rf) in pure oxygen.
To calculate the proportion of relevant records missed by each partial search, we first tallied the number of records identified at two different steps of the search process (see Table 1, Columns A and B).
Argon was added at two different steps: at the top of the gas liquid separator, carrier gas, and after the PTFE membrane, additional gas.
The phenol-oxidase cascade is inhibited, at two different steps, by Spn27A [ 18, 19] and Spn28Dc [ 20]; while tracheal melanization is regulated by Spn77Ba [ 21].
In the light of these NaPaC properties, we attempted to inactivate locally VEGF165 secreted by A431 cells at two different steps of xenograft development: by early administration of NaPaC, starting at tumour cell inoculation; and late treatment, beginning 1 week later when tumours were well established.
Changes occurring when the Gnd concentration is decreased stepwise cover a larger concentration scale of Gnd than the reverse protocol, allowing one to suggest that the resulting conformational changes in the subdomain IA of BSA involve at least three different steps.
Processing of the SP-B precursor includes proteolytic cleavage of N- and C-terminal domains in at least three different steps.
The protonation at low pH prevented three different steps: (i) the acquisition of a 3D intramolecular rearrangement required for the toxin monomer to associate (conformational gating), the formation of one of the two interfaces present per subunit and finally a transition from a non native to a native pentameric conformation.
