However this may be explained by two possible reasons, it may mean that the selection pressure shaping probe C associated rifampicin resistance is absent in our setting and secondly the small sample size may have limited this likelihood.
Firstly, the effect of scaling the brick and mortar joints to half scale was assessed, and secondly, the effect of scaling the size of the specimen without scaling the brick and mortar size was assessed.
Secondly, the size and depth distributions of the embedded Ag NPs can be controlled by choosing implantation parameters and post-implantation thermal treatment [19], which can tune the SPR spectrum of Ag NPs to match the absorption edge of TiO2.
Secondly, the size and diversity of the patient sample was limited.
This transformation seems to be closely related to the process of reordering by the growth of chemically ordered domains as, first, their boundaries interact with dislocations, and secondly, the reduction in the grain size is reached at 370 °C (cf. Fig. 6), at which temperature the LRO is already pronounced (cf. Fig. 3).
Secondly, the size of amplified fragments was between 191 bp and 427 bp, and the difference between any two fragments surpassed 100 bp, not only reducing the amplification efficiency imbalance problem [ 26], but also making the bands easy to distinguish on the electrophoretogram.
Secondly, the size of the population is relatively small.
Secondly, the size of the formed silver nanoprisms is almost identical regardless the concentration of NaBH4.
Secondly, the size of the household had a positive relationship with the probability of switching to GSU water.
Secondly, the size of the reclamation strip is usually large, which results in an uneven and occasionally shallow surface soil that isn't sufficiently deep to support plant growth.
