Four levels of vibration and noise (none, low, medium and strong) were presented to subjects, in every possible combination.
It was suggested that basicity and weak acidity are intrinsic features of the clay structure, while medium and strong acidities are induced by the exchangeable cation.
Sodium titanate nanotubes doped with potassium showed a higher amount of medium and strong basic sites than the pure sodium counterpart (NaTNT) used as a reference.
However, for crosspeaks pairs associated with the intra-residue H8/6 to H2' and H3', upper distance limits of 4.2 and 3.2 Å were employed for NOEs of medium and strong intensity, respectively48.
We set and examined two hypotheses about effects of ramp slope (1 6, 1 8, 1 10, 1 12, and 1 14) by varying ramp height (0.15 m, 0.30 m, and 0.45 m) and pushing force of wheelchair users (weak, medium, and strong group).
For this purpose, the experimental design took into consideration different factors including 3 different flour strengths (weak, medium and strong), 4 levels of TG (0, 0.05, 0.1 and 0.2% of flour weight), two levels of VG (0 and 1% of flour weight) and 4 different resting times (45, 70, 90 and 135 min).
According to CMRR, roof can be classified into three types: weak roof, medium roof and strong roof.
Generally, the acid sites were classified into the weak (≤200 °C), medium (200 350 °C) and strong (≥350 °C) acid sites [21].
The neck is of medium length and strong, often slightly arched.
Results were classified as negative, trace, weak positive, medium positive, and strong positive.
Results were read after five minutes and classified as negative, trace, weak positive, medium positive, and strong positive.
