The phrase "and thirdly by using" is correct and usable in written English.
It can be used when enumerating points or arguments in a structured manner, particularly in essays or presentations.
Example: "The benefits of exercise can be summarized in three ways: firstly by improving physical health, secondly by enhancing mental well-being, and thirdly by using it as a social activity."
Alternatives: "and thirdly through" or "and thirdly by means of".
Thirdly, by using a representative sample of practitioners and patients it seems appropriate to generalize findings to the entire population of patients and general practices.
Thirdly, by using the Lyapunov theory, the stability of the proposed algorithm is proven.
Thirdly, by using the 3-D finite element method, the power generation performances of the proposed PHE-LVM are evaluated.
Firstly using the multi-allelic loci detected by single SSR, RFLP or SNP markers, secondly using sequence information from these markers and thirdly using repulsion phase analysis.
Thirdly, the reliability of the identified target-relationship pairs of miRNAs-mRNAs was assessed and confirmed by using both TargetScan and miRanda databases.
Thirdly, composites prepared by using BC in conjunction with other polymers are explored, and the research on BC for application in skin tissue engineering is addressed.
Thirdly, we confirmed by using CD21 immunostaining for follicular dendritic cell that inflammation destroys these cells, hence reducing the number of potentially positive samples (fig 1).
Thirdly, composite hydrogels prepared by using cellulose in conjunction with other polymers through blending, formation of polyelectrolyte complexes, and interpenetrating polymer networks (IPNs) technology are addressed.
Thirdly, the hexapod robot with bounding gait was controlled by proportional-derivative control algorithm and was carried out by using spring loaded inverted pendulum model.
Table 5 presents the number of adverse events found in this study summarised by system organ class (SOC), firstly as coded by SKB using ADECS, secondly as reported by Keller and colleagues (who reported only adverse events that occurred at frequency of more than 5%), and thirdly as coded by us using MedDRA.
