The fictitious degrees of polymerization of styrene (FDPs) for DPE-NMe2 and DPE-SiH/NMe2 were calculated to be 37 and 13, respectively, suggesting that using DPE derivatives containing an electron-withdrawing group in the synthesis of sequence-controlled polymers might lead to a more precise structure.
Additionally, we used these initial optimized structures (one for HF and two for SO3) as input files for next optimization at the stronger basis set of 6-31G (d,p)/(B3LYP, lanl2dz for Pt) to get more precise structure properties.
Comparing characteristics of seismic wave propagation between the southwestern Japan and Kanto area examined in this study could reveal more precise structure and fluid distribution in the subducting oceanic crust of the Philippine Sea plate.
To establish a more precise structure of general thoracic surgery a working group has been established by the European Association for Cardio-thoracic SurgEACTSEandS) and the ESTS.
Sequence analyses confirmed the presence of well-conserved DIRS1-like retrotransposons in 28 species, including at least 14 species that were not previously known to host such elements, and allowed us to define a more precise structure of the DIRS1-like retrotransposons, especially in their terminal repeats.
This is more or less the structure of all subsequent versions, printed or filmed; what differs is first the scene with which the process begins and, more important, the precise structuring principle of the movement itself.
Its protolytic centers are neutral, as the core parent is derived from the source structure by adding/removing the appropriate number of protons (to be more precise, the structure as a whole is neutralized).
By making the blade in smaller sections, it's possible to make more precise aerodynamic structures, improving performance, he says.
Recently, the remarkable advancement of technologies for studying seismic refraction and reflection (e.g., GPS navigation systems, Ocean Bottom Seismographs (OBS), analytical methods, calculation performance of computers) has allowed for the acquisition of more precise velocity structures (e.g., Kasahara et al., 2007; Oshida et al., 2008).
The more precise three dimensional structure of the carbon nanotubes and activated carbon can be revealed by using 3D-TEM combined with HRTEM.
