The key measures "degree of difficulty of conversion" and "degree of exhaustion" are introduced to define the optimal modes in more general terms.
This large energy difference indicates the difficulty of the conversion of structures (b) to (c) which argued the step wise process of nucleophilic attack.
Nevertheless, due to the reported efficacy of total hip arthroplasty and the typical age group in those patients with osteonecrosis, it has recently been questioned whether these invasive procedures are appropriate, given the potential difficulty of later conversion to a hip replacement [ 4, 40].
Lengthening of the PF further increases the difficulty of lateral bond conversion by increasing the conversion barrier height (4→5, Fig. 7b, right panel).
The difficulties of a conversion by a Catholic Archbishop and Prince-elector of the Holy Roman Empire had been faced before: Hermann von Wied had also converted to Protestantism, and had resigned from his office.
On the one hand, the inherent difficulty in conversion of lignocellulosic biomass into biofuels calls for development of robust biofuel-producing microbes.
However, the micropore of SAPO-11 inhibits its application in long-chain paraffin isomerization, due to their difficulty of mass transfer and catalytic conversion inside the pores.
It should be noted that these nanoparticles usually have very small diameters (2 to 5 nm), and thus, it is difficult for them to form a well continuous inorganic network, leading to the difficulty of electron transfer and low photoelectric conversion efficiency[33].
In our study, the conversion rate decreased from 22.2%% in phase 1 9 % in phase 2; while reasons of conversions in phase 1 was intra-operative complications, in phase 2 it was due to the unexpected finding (intra-operative difficulties including ventilation problems due to high adiposity) restricting the operating technique.
Or he'd get the conversion done and the difficulty of running the school would overwhelm him.
